Description

Technical Field

[0001] The utility model relates to a stamping positioning tool for an automobile bearing cover plate. Background Art

[0002] Stamping is a forming method that relies on a press and a die to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. A continuous stamping die refers to a cold stamping die that uses a strip of raw material to simultaneously complete multiple stamping processes at different stations on a die. The strip of material moves a fixed distance, once per stroke, until the finished product is obtained. In order to ensure that the raw material does not shift during stamping, the continuous stamping die must also be equipped with a matching positioning device.

[0003] The automobile bearing cover plate is a sheet metal part, and its processing method is stamping. In order to improve production efficiency, a continuous stamping die is used. However, the positioning device in the existing continuous stamping die for processing automobile bearing cover plates can only fix the strip material from the top. There is a lack of effective constraints on the bottom and front and rear sides of the strip material, which makes it easy for the strip material to shift during stamping, thereby affecting the processing accuracy. At the same time, there is a problem of long positioning stroke, which leads to low positioning efficiency, which needs further improvement. Utility Model Content

[0041] Working principle:

[0042] The strip material is extended horizontally between the pressure plate 2510 and the loading strip 2521 in any positioning assembly 25, and then the telescopic ends of the two lifting cylinders 252 are driven to extend outward to drive the two side blocks 254 and the two first lifting plates 255 to move downward with the help of the second lifting plate 253, and then the telescopic ends of each positioning cylinder 258 are driven to extend outward to drive the pressure plate 2510 to continue to move downward with the help of each lifting block 2511, and at the same time drive the two clamping blocks 259 to move downward, and then with the help of each inclined T-shaped bar 2591 on the clamping block 259 and the corresponding inclined T-shaped groove 2561 on a guide block 256 on the same side, the two clamping blocks 259 are driven to move closer to each other while moving downward, until the inner walls of the two clamping blocks 259 are respectively pressed against the front and rear outer walls of the strip material, at this time, the pressure plate 2510 is just pressed against the top outer wall of the strip material.

[0043] In the above process, it is also necessary to drive the telescopic ends of the two traction cylinders 2518 in each driving unit of the second lifting unit to extend outward, thereby driving the first driving block 2517 and the second driving block 2519 to move backward and forward respectively to approach each other, so as to drive the two traction blocks 2515 to move upward with the help of the cooperation between the two first inclined grooves 25171 on the first driving block 2517 and the two inclined guide strips 25152 in the first guide hole 25151, and then slowly lift up the loading strip 2521 with the help of the loading plate 2514 until the top of the loading strip 2521 is pressed against the bottom outer wall of the strip material, so that the strip material can be reliably fixed from the front, back, up and down directions to achieve positioning, and then the strip material can be stamped with the help of matching stamping tools.

[0044] The utility model can fix the strip material from both upper and lower directions at the same time, thereby shortening the time required for completing the positioning of the strip material, thereby improving the positioning efficiency; and can also clamp and fix the front and rear sides of the strip material during stamping, thereby completely avoiding the displacement of the strip material during stamping, thereby effectively ensuring the processing accuracy.
