Metal Slitting Machine Work Process

The metal slitting machine is a device for longitudinal cutting of wide roll material. So each industry has the word in use, we can understand from the scope of use.

Metal slitting machine is mainly used for sub-metal coil: This is the current metal cutting equipment in the mainstream products, the market is often visible. Such as strip strip, stainless steel, copper ... ... its main for steel processing manufacturers (steel market operators, rolling mill manufacturers, electrical industry, cars, stamping parts, etc.).


Metal slitting machine structure: from the open book (unwinding), the introduction of materials, sub-slitting, coiling (rewinding) and other components of the equipment. Its main function is to set the length of the wide-length material cut into a narrow size of the coil, for the future to prepare other processing processes.


Metal slitting machine advantages: reasonable layout, easy operation, high degree of automation, high production efficiency, high precision, can be processed all kinds of cold-rolled, hot-rolled coil, silicon steel plate, stainless steel plate, color plate, aluminum and electroplating or After coating all kinds of metal sheet.


Metal slitting machine use: Widely used in automobiles, agricultural vehicles, containers, home appliances, packaging, building materials and other metal sheet processing industry.


The structure and function of metal slitting machine:

1, storage station: for the processing of raw materials to be stored, also known as raw materials standby, generally custom 1-2.


2, transport trolley: the storage station stored in the standby material into the unwinder, and through the rise, fall, before and after the move and other functions of raw materials into the open reel, usually using visual / manual, etc., can also be made Fully automatic "V" plane or roller plane.


3, uncoiler: usually use a single cantilever type, such as the larger weight of raw materials, the need to add the end of the reel in the auxiliary support, open-book base is usually parallel to the direction of movement along the machine, can quickly and accurately complete the raw material, The general use of visual / after the move, can also be made automatically automatic alignment, but need to increase the cost of expensive.


There are also double open head type:

A. Cone-head open-type reel: Cone-head open-top for the cone to the cone within the scope of any diameter of the original material, but easy to cause damage to the inner edge of the raw material, generally applicable to more than 3mm thick raw materials.

B. Ladder-type open-shelf: the way the open head only applies to multi-standard internal diameter of raw materials, generally divided into 2 to 4, but the operation is relatively no single-head cantilever intuitive and convenient, its front and rear movement is usually driven by the cylinder.


4, pinch, leveling and plate shear: folder to send the wheel is usually used hydraulic, pneumatic and electric lifting device, leveling machine generally use electric lift and worm gear structure to ensure the stability of the positioning of the lift, the head shear Usually using hydraulic shear bed to ensure that the raw material into the disc cut the end of the flat. The drive is generally driven by stepless speed motor to ensure that the machine speed and smooth synchronization.


5, living sets of pit: also known as raw material storage buffer pits, usually 2 to 4 meters in depth, the length of 3 to 4 meters, as the raw material in the chucking and shearing machine speed matching buffer device, usually using hydraulic electric lift Platform, the raw materials into the folder and the lateral guide device, the transition board generally use roller and anti-scratch materials as raw materials to contact the transition surface.


6, side guide and clamping device: side guide is as a raw material in the fast forward when the lateral positioning device, usually using vertical roller or vertical plate structure, to ensure that the raw materials in the longitudinal positioning when the slitting, Edge caused by the finished product shear width is poor; clamping device is generally used on the roller, to ensure that the raw material before cutting the flatness.


7, disc scissors: disc scissors, also known as slitting machine, the production of the core of the machine device, through the blade and spacer sets of different combinations to achieve the width of different finished products. The accuracy of the sub-axis of the shaft is very high. Its longitudinal beating, lateral deflection and its mechanical strength have determined the accuracy of sub-finished products. Its accessories round blade, blade spacer and other precision requirements also determine the accuracy of the finished product and row knife time, a direct impact on processing output. The return of the material generally there are two kinds of apron material and pressure plate back to the two, blade and blade spacer sets of nut positioning and more expensive hydraulic shaft lock and so on.


8, the transition platform: the transition platform is to cut the finished product transition to the finished product sets of buffer pits within the device, requiring its close part with the disc can be set off to facilitate the blade set and finished product quality and other functions, in the fixed part of the The tailings press plate prevents the finished product from falling into the darts after the cut.


9, waste side coiler: waste side coiler using a disc-type collection device, the material cut after the waste side of the waste into a bundle, in order to facilitate the waste silk storage and transportation, generally auxiliary screw-type device Or cam link type guide device, which drives the use of variable speed and tension control motor drive, supplemented by emergency stop brake brake, manual unloading and automatic discharge in two ways.


10, finished buffer pits: length of about 3 to 4 meters, depending on the depth of the material thickness, the number of points and raw material diameter and other parameters of the usual depth of about 4 to 7 meters. In the sub-cut a number of thin sheet material, due to the thickness of the original material and the tension of the production station tension uneven factors such as the length of the finished product is not the same phenomenon, live sets of pits from the speed buffer and the amount of storage and other functions.


11, before the separation device: the former separation device is finished into the tension before the production station to give a pre-separation separation, so that the finished product with tension in the extrusion will not appear cross, stacking phenomenon, generally by the two separate positioning and anti- Pressure roller composition, the front section can be used to lift the separation of the shaft, to prevent the pressure plate due to pressure caused by the plastic wheel deformation, separation of the use of movable guide rails can be flexible and easy to pull out the separation axis to facilitate the segregation row.


12, tension production station: tension production station is divided into the traditional plate tension station, the more advanced belt tension station and roller tension station, usually using adjustable hydraulic pressure down to achieve the function of tension, belt and roller A sliding frictional resistance is applied to generate tension.


A. The traditional tension station due to the tension of the beginning of the pad and the relative sliding of the strip may cause the surface easy to scratch the plate scratches, scratches and other phenomena, the resulting tension is almost all the surface is not easy to hurt the thickness of the material or non-bright mirror panel collection.

B. Belt tension station is generated by the difference between the sliding resistance between the belt and the inner tension roller, and is suitable for the protection of the surface of the bright mirror panel. Due to the belt gap and other reasons may be on the individual thickness and narrowband caused by material damage.

C. The roller tension station is suitable for the tension of the sheet below 0.5, and its working principle is to produce tension by the resistance of the roller or the speed difference between the roll and the belt, which may cause the roller surface to damage and can not guarantee its use performance.


Conventional tension generation station due to uniform tension, tension adjustment is simple, simple structure, easy maintenance and other factors, and easily lead to the finished product of the scratches can be resolved through the surface film, and affordable, so favored by the majority of users.


13, pinch and shearing machine: pinch machine for the finished product into the winder when the power supply device or in the shear shearing machine on the finished product after the material into the winder of the power supply device, generally used Gas, oil, electricity and other driving methods to complete its proper function, the shear bed is usually used hydraulic shear bed, in the finished product from the cross-cutting function, followed by finished product guide and flattening wheel.


14, winding machine: winding machine, also known as finished product rewinder, is the finished part of the finished product rewinding volume into the volume of the device, the reel can be used to expand the structure to facilitate the smooth exit of the finished product, with a separate device to prevent the finished product With the cross-belt, the belt and the finished side of the winding surface smooth, the use of hydraulic lift, supplemented by counter-valve in the finished product can be increased when the resistance can be increased automatically, push plate device using hydraulic drive, the finished product from the reel Smooth launch. In the collection of heavier finished product volume, supplemented by auxiliary support device. The drive motor is driven by a constant power DC motor to ensure that the winding force is taken while the large coil material is being wound and the tape is not compressed. There are fast brake brakes, to prevent pull with a knife.


15, unloading trolley: the use of hydraulic lift, "V" -type structure design to ensure that the finished product with the stability of the coil, through the hydraulic or electric drive the finished product roll out of the reel and can reach a convenient place to play. In order to prevent the finished product with overturned, generally have anti-roll up the roller jack.
