High Precision Molding and Quality Assurance

1) Orthoscopic feeder unit

Common feeding machines use feeding rollers to feed materials. When the materials touch the block, they can be cut to a specified length. At this time, due to friction between the material and the block, sometimes the material will be scratched and other bad conditions. In order to prevent this phenomenon, a straight-line feeding device is installed, which uses straight-line clamp to clamp material into forging equipment. Because there is no sliding between the material and the clamp, high precision shearing can be achieved even without the block.

２)Punching shear device

When the blank is sheared, because the shearing method is adopted, the shearing inclination will occur and the shearing right angle with good end face cannot be obtained. Increasing the shear speed can improve the sheared edge. In the initial stage of shearing process, the cutter of common shearing machine accelerates at zero velocity and shears at the same time. idling stopping distance is set before the punching shear, and the shearing process begins at the end of the acceleration stage. Therefore, it can obtain about 2m/s shear speed and obtain good blank end face.

3) Gapless extrusion rod device

In order to produce high precision products, it is very important to ensure the accuracy of core deviation to ensure the accuracy of inner and outer diameters of products. Because the extrusion rod is formed by the reciprocating movement of the force piston, the sliding surface must have clearance. This gap will affect the accuracy of the product. Therefore, the accuracy of core deviation can be improved by using roller bearings to slide the sliding surface and making the clearance between the extrusion rod and the sliding surface zero.

4) SP Conveyor Belt to Prevent Injury

The forming machine is a horizontal forging press. In the final forming process, the blank separated from the die will fall freely on the chute at the lower part of the forging and pressing part. Scratches on falling billet will affect product quality. To solve this problem, the SP conveyor belt is developed, which opens through holes on the frame and extends the product discharge conveyor belt below the final conveyor position. Because the product landed soft on the SP conveyor belt under the conveyor manipulator, there were no scratches on the blank.
