Technical Field

[0001] The utility model relates to stamping processing equipment, in particular to a stamping forming die for left and right longitudinal beam parts. Background Art

[0002] During the production process of the left and right longitudinal beam parts of automobiles, a mechanical suction cup is used to pick up the material and place it into the mold for stamping. Since the mold cannot identify whether there is a piece of material, the robot occasionally places the material repeatedly, causing damage to the mold during processing and resulting in high losses. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a stamping die for left and right longitudinal beam parts which can increase the service life of the die.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: the left and right longitudinal beam parts stamping forming die, including an upper die and a lower die, the upper die includes an upper die base, the upper die base is provided with an upper mounting groove, a plurality of nitrogen springs are provided in the upper mounting groove, an upper die floating lifting material block is provided on the nitrogen spring, a plurality of upper pressing material block groups are provided on the upper die floating lifting material block, a plurality of bottom supporting blocks are provided at the bottom of the upper mounting groove, a plurality of upper limit blocks that match the edge of the upper die floating lifting material block are provided around the notch of the upper mounting groove on the upper mounting seat, a pair of upper side forming blocks for forming the large curved surface part of the outer side of the workpiece are provided on the upper die base, and the sides of the upper side forming blocks are provided with wear-resistant blocks;

[0005] The lower die includes a lower die base, a lower mounting groove is provided on the lower die base, a lower forming block is detachably provided in the lower mounting groove, an inner positioning block for limiting the inner edge of the workpiece is provided in the middle of the lower forming block, and a plurality of outer positioning blocks for limiting the outer edge of the workpiece are provided around the notch of the lower mounting groove on the lower die base. The outer positioning blocks are L-shaped and have waist-shaped holes on the part connected to the lower die base.

[0006] A trigger block is hinged on the upper part of at least two outer positioning blocks corresponding to the position of the workpiece. The outer positioning block is provided with a spring to push the trigger block toward the workpiece. A detection device for detecting the trigger block is provided on the outer positioning block at a position corresponding to the position after the trigger block compression spring returns. When the workpiece is placed on the lower forming block, the trigger block will be pressed back and the detection device will be triggered.

[0007] As a preferred solution, the lower die base is detachably provided with a plurality of lower positioning blocks that cooperate with each upper limit block.

[0008] As a preferred solution, a plurality of upper positioning blocks that cooperate with the respective upper limit blocks are detachably provided on the edge of the upper mold floating lift pressure block.

[0009] As a preferred solution, the outer periphery of the upper mold floating lift pressure block is detachably provided with a plurality of side wear-resistant blocks.

[0010] The beneficial effects of the utility model are:

[0011] A detection device is added to this mold. When the robot puts the blank in and the workpiece is placed on the lower forming block, the trigger block will be pressed back and the detection device will be triggered. The robot suction cup will not put the blank in repeatedly, thereby avoiding damage to the stamping mold. This also allows this mold to be used for linked induction production, improving efficiency and production stability.

[0012] Since the lower die base is detachably provided with a plurality of lower positioning blocks that cooperate with the upper limit blocks, the upper limit blocks are prevented from directly hitting the lower die base when the mold is closed, thereby extending the service life of the lower die base.

[0013] Since a plurality of upper positioning blocks cooperating with the upper limit blocks are detachably provided on the edge of the upper mold floating and pressurizing block, the upper positioning blocks are prevented from directly hitting the upper mold floating and pressurizing block, thereby extending the service life of the upper mold floating and pressurizing block.

[0014] Since a plurality of side wear-resistant blocks are detachably provided on the outer periphery of the upper die floating press block, the side wear-resistant blocks can be replaced after being worn, thereby extending the service life of the upper die floating block and reducing the cost of using the die.
