Description

Technical Field

[0001] The utility model belongs to the technical field of stamping production, in particular to a metal fitting stamping anti-deviation structure. Background Art

[0002] Stamping production is a common metal processing method used to manufacture metal parts and products. It is done by placing a metal sheet in a stamping machine and using the die on the stamping machine to apply pressure to the metal sheet to cause it to undergo plastic deformation, ultimately forming the desired parts or products. In the process of stamping metal accessories, in order to prevent the stamped parts from shifting during stamping, they need to be clamped and fixed.

[0003] After retrieval, the authorization announcement number CN218168360U and the authorization announcement date 2022.12.30 disclose an anti-deviation sleeve for metal stamping, including a base and a stamping lower die. One side of the base is provided with an extension block, and the stamping lower die is arranged on the upper surface of the extension block. Two sets of bidirectional screws are also arranged on the extension block, and the bidirectional screws are provided with limit plates for preventing the stamping parts from deviating. One end of the same side of the two sets of bidirectional screws extends out of the side wall of the extension block and is fixed to the center of the gear. There is an empty groove inside the extension block, and an electromagnet for magnetic adsorption of the stamping parts is placed in the empty groove. The utility model opens a slide groove on the surface of the extension block on the base, and a bidirectional screw is arranged in the slide groove. The forward and reverse motors are used to drive two meshing gears to rotate, so that the rotation of the bidirectional screw changes the spacing between its two nuts, and also changes the distance between the limit plates connected together between the nuts on the two bidirectional screws. The two limit plates are used to squeeze the two sides of the stamping part so that it is not easy to shift on the horizontal plane during stamping.

[0004] However, the existing technology has the following shortcomings:

[0005] 1. When the above-mentioned anti-deviation sleeve for metal stamping is used, the stamping part is placed between two limit plates and the stamping part is located on the upper wall of the lower die to perform the stamping operation. However, in actual operation, when the stamping parts of the same specification need to be mass-produced, the position of the stamping part needs to be adjusted before each stamping so that the stamping part is located at the correct position of the upper wall of the lower die, which reduces the stamping efficiency;

[0006] 2. When the above-mentioned anti-deviation sleeve for metal stamping is in use, the two limit plates are moved to clamp the stamping part and the stamping operation can be carried out. However, in actual use, the two limit plates can only limit the left and right directions of the stamping part, and the force during stamping is extremely large. The action of the electromagnet cannot avoid the forward and backward movement of the stamping part during stamping, resulting in poor anti-deviation effect of the stamping part. Utility Model Content

[0007] The purpose of the utility model is to provide a metal accessory stamping anti-deviation structure, which can position the stamped parts and prevent them from deviating to the left and backward through two positioning plates, and can prevent the stamped parts from deviating to the front and right through two abutment plates. This solves the problem that the prior art needs to adjust the position of the stamped parts before each stamping so that the stamped parts are located in the correct position on the upper wall of the lower mold, which reduces the stamping efficiency. In addition, the prior art cannot avoid the forward and backward movement of the stamped parts during stamping due to the action of the electromagnet, which leads to poor anti-deviation effect of the stamped parts.

[0008] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0009] The utility model is a metal fitting stamping anti-deviation structure, comprising a bottom plate, a lower mold is arranged above the middle position of the bottom plate, a positioning plate is arranged on the left and rear of the lower mold, a mounting box is arranged outside the positioning plate away from the lower mold, a screw sleeve is fixed on the side wall of the mounting box away from the lower mold, and a screw is arranged inside the screw sleeve away from the lower mold;

[0010] Cylinders are arranged on the right and front of the lower mold, abutment plates are fixed to one end of the cylinder close to the lower mold, a movable plate is fixed to one end of the cylinder away from the lower mold, and a second mounting box is arranged outside the lower side of the movable plate.

[0011] Furthermore, the positioning plate is arranged in an L-shape, and reinforcing ribs are fixed at the corners on the lower side of the positioning plate, and the reinforcing ribs are arranged in a triangular shape.

[0012] Furthermore, the positioning plate is clearance-matched with the installation box 1, and a bolt 1 is threadedly connected on the side wall of the installation box 1 away from the lower mold, and the threaded end of the bolt 1 abuts against the corresponding positioning plate.

[0013] Furthermore, bosses are fixed to both side walls of the installation box 1, guide strips are fixed to the outer sides of the bosses corresponding to the upper walls of the bottom plate, and the bosses are slidably connected to the guide strips.

[0014] Furthermore, the screw is threadedly connected to the screw sleeve, a circular plate is fixed to one end of the screw away from the lower mold, and an operating rod is fixed to the edge of the circular plate away from the lower mold.

[0015] Furthermore, a side plate is provided on one side of the circular plate close to the lower mold, and the side plate is fixedly connected to the bottom plate, and the screw is rotatably connected to the side plate via a bearing.

[0016] Furthermore, a cushion block is provided below the lower mold, and the cushion block is fixedly connected to the bottom plate, and the lower mold and the cushion block are detachably fixedly connected.

[0017] Furthermore, the movable plate is clearance-matched with the second installation box, and the second bolt is threadedly connected to a side of the second installation box away from the lower mold, and the threaded end of the second bolt abuts against the corresponding movable plate.

[0018] Furthermore, four corners of the bottom plate are provided with through holes.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model sets a positioning plate, rotates the screw rod to drive the corresponding screw sleeve to move, and finally drives the positioning plate to move, so that the rear end and the left end of the stamping part are both in contact with the corresponding positioning plate, and the stamping part is adjusted to the correct position, thereby realizing the positioning of the stamping part by using the positioning plate. It is suitable for stamping stamping parts of the same specification in large quantities, and improves the stamping efficiency of stamping parts of the same specification in large quantities. At the same time, the positioning plate can also prevent the stamping part from moving backward and leftward.

[0021] 2. The utility model sets an abutment plate and uses the cylinder to make the corresponding abutment plate abut against the right end and the front end of the stamping part, so as to prevent the stamping part from moving to the right and forward. Therefore, through the cooperation of the positioning plate and the abutment plate, the stamping part is prevented from moving forward, backward, left and right, thereby improving the anti-deviating effect of the stamping part during stamping.
