Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a positioning tool for stamping automobile parts. Background Art

[0002] Auto parts are the various units that constitute the overall processing of auto parts, as well as the products that serve the processing of auto parts. Auto parts are mostly irregular in shape and have relatively uneven surfaces. Stamping is a forming processing method that relies on a press and a die to apply external force to plates, strips, pipes, and profiles to cause them to undergo plastic deformation or separation, thereby obtaining workpieces of the desired shape and size. Compared with castings and forgings, stamping parts are thin, uniform, light, and strong; stamping can produce workpieces with reinforcing ribs, ribs, undulations, or flanging that are difficult to manufacture by other methods, in order to improve their rigidity. Positioning tooling is usually used when stamping auto parts. Positioning tooling refers to process equipment that positions and fixes auto parts during the processing and manufacturing of auto parts.

[0003] The existing positioning tool for stamping automobile parts does not have a demoulding function. The workpiece after stamping needs to be manually demoulded, which is cumbersome and affects the work efficiency of the staff. Therefore, a positioning tool for stamping automobile parts is proposed.

[0004] A convenient automobile part stamping positioning device disclosed in the announcement number CN220461973U, although, the convenient automobile part stamping positioning device includes a base, a stamping bracket, a fixing component and a stamping component, the two sides of the top of the base are fixedly installed with stamping brackets, the inner side of the base is provided with a placement groove, the inner side of the placement groove is placed with a stamping part, the inner side of the placement groove is movably installed with a fixing component, the upper part of the fixing component is movably installed with a stamping component, the stamping component is arranged below the stamping bracket, the automobile part is stably fixed by the fixing component, and then the fixed automobile part is stamped by the stamping component; the utility model uses the mutual cooperation between the telescopic cylinder, the push plate, the horizontal support plate, the rotating rod, the rotating handle and the lower pressure plate, and drives the push plate to be fixed on the left and right sides by the telescopic cylinder, and the two groups of push plates can be adjusted according to the actual width of the stamping parts. This structure can realize the adjustment and clamping of stamping parts of different widths.

[0005] Although the above patent has achieved the mutual coordination between the telescopic cylinder, the push plate, the cross support plate, the rotating rod, the rotating handle and the lower pressure plate, and the push plate is driven by the telescopic cylinder to fix the left and right sides, the two sets of push plates can be adjusted according to the actual width of the stamped parts. This structure can realize the adjustable clamping processing of stamped parts of different widths; however, the device lacks the function of buffering and shock absorbing the clamping device, which can absorb and disperse the impact force and vibration generated during the clamping process, thereby reducing damage to parts and equipment and extending their service life.

[0006] Therefore, it is necessary to invent a positioning tool for automobile parts stamping to solve the above problems. Utility Model Content
