Description

[Technical Field]

[0001] This invention relates to the field of stamping dies, specifically a cover plate stamping die. [Background Technology]

[0002] Stamping dies are important processing tools in modern industrial production. In the previous stamping process of automotive circuit board cover plates, the temperature of the cutting edge rose due to prolonged stamping. The high temperature of the cutting edge caused aluminum to stick to the cutting edge during stamping. The original cooling method was to blow air onto the cutting edge. However, this cooling method caused aluminum chips to splash onto the workpiece and create indentations during stamping. In addition, if the internal cavity size of the workpiece changes, there will be a large gap between the workpiece and the lower module or the workpiece cannot be placed. The positioning part of the lower module does not have a flexible fixing method. At the same time, the lower module is a whole piece, which is not conducive to replacement.

[0003] Therefore, it is necessary to improve existing technologies. [Summary of the Invention]

[0004] The technical problems to be solved by this invention are: the high-temperature blade cooling method and the lack of an elastic fixing method for the lower module positioning part, and the fact that the lower module is a single piece, which is not conducive to replacement.

[0005] The solution to the technical problem of this invention is: a cover plate punching die, comprising:

[0006] The mold foot includes an upper mold foot and a lower mold foot; the upper mold foot is connected to the upper template and is located above the upper template; the lower mold foot is connected to the lower template and is located below the lower template.

[0007] A spring force unit includes: a spring, a spring plate, and a height-equalizing screw. The spring is positioned above and close to the spring plate to provide spring force to the spring plate, enabling it to push the stripper plate connected to the spring plate back to its original position when the die moves upward. The spring plate is positioned above the upper die plate and is connected to the stripper plate through a connecting rod. It cooperates with the spring positioned above it to push the stripper plate back to its original position using spring force when the die moves upward. The spring plate has a water passage hole through which a water supply line passes. The height-equalizing screw passes through the spring and the spring plate and is locked to the upper die plate to provide a track for the movement of the spring plate.

[0008] The upper template is a cuboid with holes on both sides. A guide sleeve is attached below the holes, through which a guide post extends during punching.

[0009] The lower template is a cuboid parallel to the upper template, which is used to support the cylinder fixing unit, the lower guide plate and the limiting post, and has a through hole for accommodating the pipeline required by the cylinder.

[0010] The positioning unit includes guide pillars, guide sleeves, and limiting pillars. The guide pillars are locked onto the lower template and engage with the guide sleeves during punching, extending into the holes of the upper template to fix the overall mold. The guide sleeves are locked onto the lower part of the upper template and engage with the guide pillars during punching to fix the overall mold. The limiting pillars are locked onto the four corners of the lower template to abut against the upper template and create a limiting effect when the die moves downward.

[0011] The punching unit includes: an upper guide plate, a punching blade, a stripper plate, a cylinder fixing unit, and a lower guide plate;

[0012] The upper guide plate is locked to the lower part of the upper template and has a water passage hole through which the water supply pipeline passes. The upper guide plate has a positioning post at each of its four corners. The guide post extends into the hole of the stripper plate and is used to provide a track for the stripper plate to move.

[0013] The punching blade is locked to the four sides of the upper guide plate, and the blade is set at an angle to punch the workpiece.

[0014] The stripper plate is located below the upper guide plate and is connected to the spring plate through a connecting rod. It has a hole at each of its four corners to allow a positioning post in the upper guide plate to extend into, providing positioning during the stripper plate's movement. One side of the stripper plate has a clearance hole to accommodate the protruding part of the workpiece. The stripper plate has a water channel inside, and a water channel hole at the top for a pipeline to extend into. The water channel is arranged in a grid pattern inside the stripper plate, and several water outlets are located on the four sides of the stripper plate. Each water outlet is a hole that connects to the water channel and extends to the outside of the stripper plate. The opening connected to the water channel is smaller than the opening extending to the outside of the stripper plate. The height of the water outlet is set according to the angle of the cutting edge.

[0015] The cylinder fixing unit includes: a fixing plate, a fixing block, a cylinder, a connecting rod, and guide wheels. The fixing plate is mounted on the lower guide plate and has a through hole for accommodating the pipeline required by the cylinder. The fixing block consists of a corner fixing block and four side fixing blocks. The corner fixing block is located at one corner of the fixing plate, and the side fixing blocks are located on the four sides of the fixing plate. There is a gap between the corner fixing block and the two side fixing blocks to accommodate the connecting rod and guide wheels. The fixing block has a groove that matches the shape of the workpiece and is used to cooperate with the cylinder, connecting rod, and guide wheels to fix the workpiece in the punching position. The cylinder is mounted on the fixing plate, with its telescopic part facing the corner fixing block and connected to the connecting rod to drive the connecting rod and guide wheels to press them tightly against the workpiece. The connecting rod is a V-shaped rod with a guide wheel at each end. The guide wheels are used to press the workpiece tightly.

[0016] Preferably, the guide wheel is made of POM;

[0017] The lower guide plate carries the cylinder fixing unit and is mounted on the lower template. It has a through hole for accommodating the pipeline required by the cylinder. [Attached Image Description]
