New energy vehicle parts require higher precision, greater durability, and lighter weight, which has driven continuous innovation in mold technology.

[0003] However, when the current mold is used to produce the hook that connects the car base frame, the bending accuracy of the hook cannot be fully controlled during the forming process, so that the accuracy of the bending angle of the hook cannot be guaranteed during the forming process.

[0004] The utility model application number CN202223586686.6 discloses a side bending die for manufacturing automotive parts.

A lower pressure head is provided on one side of the bottom of the upper die base, and a sliding connection block is provided inside the lower pressure head. A side pressure mechanism is fixedly connected to the side of the top of the sliding connection block, and the side pressure mechanism and the lower pressure head are on different sides. A side pressure head is fixedly connected to the side of the side pressure mechanism, and the automotive part body is provided inside the side pressure head. When the mold is closed, the lower pressure head moves vertically downward, simultaneously driving the sliding connection block, the side pressure mechanism, and the side pressure head horizontally toward the side of the automotive part body to achieve bending of the side of the automotive part body. This utility model solves the problem that existing automotive part manufacturing dies are not convenient for automatically bending the sides of automotive parts.

[0005] This application bends the side of the auto part by placing a pressure measuring mechanism on the inner side of the auto part.

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below.

[0027] like Figures 1 to 5 As shown, a forming die for automobile parts includes: a pressing component 1 for pressing a hook, a clamping component 2 for clamping the hook, a fixing component 3, and a detection component 5 for detecting the degree of pressing of the hook.

[0028] During the manufacturing process of automotive parts, the hooks at the bottom of the frame that connect the auto parts play the role of connecting the frame. At the same time, the bending angle of the hook determines the strength of the connection and the difficulty of disassembling the hook, so the bending angle of the hook needs to be effectively and accurately adjusted.

[0029] First, the hook is fixed by the clamping assembly 2, which includes a rotating motor 21, a bidirectional screw 22, a clamping block 23, and a placement platform 24; the output end of the rotating motor 21 is fixedly connected to the bidirectional screw 22, and opposite threads are provided at both ends of the bidirectional screw 22. The bidirectional screw 22 is threadedly connected to the clamping block 23, and the clamping block 23 abuts against the placement platform 24; by placing the hook on the placement platform 24, the hook is wound around the two groups of cylinders of the placement platform 24. At the same time, by starting the rotating motor 21, the two groups of clamping blocks 23 are driven to move toward the placement platform 24 at the same time, which plays a top role on the hook wound on the placement platform 24, and slowly squeezes its bent part to prevent the hook from breaking due to excessive speed;

[0030] At the same time, the clamping block 23 squeezes the hook left and right, which can meet the bending work of hooks of different thicknesses, so that hooks requiring different strength connections can all be subjected to bending forces.

[0031] The cam 32 is pressed against the top of the cam 32 and the cam 33 is engaged with the cam 32, and the cam 33 is engaged with the cam 32.

[0032] A scale bar 6 is provided at the bottom of the fixed component 3, and the sliding push rod 31 is perpendicular to the scale line on the scale bar 6; when moving the sliding push rod 31, by comparing with the scale bar 6, it is possible to clearly know the amplitude by which the sliding push rod 31 needs to be pushed and rotated, so as to accurately make the clamping block 23 squeeze the hook at the required angle, thereby facilitating the forming of the hook and the change of the angle.

[0033] At the same time, the positioning rod 32 can be inserted in multiple places, so that the sliding push rod 31 can rotate around it with a larger range, and the range it can push is also expanded, so as to solve the problem that the position is not easy to change when squeezing the hook.

[0034] At the same time, during the forming process of the hook, squeezing its bending position may cause its vertical direction to deviate, so the top of the hook is clamped by setting a pressing assembly 1, and the pressing assembly 1 is composed of a cylinder 11 and a pressing head 12; the cylinder 11 is fixedly connected to the pressing head 12, and the pressing head 12 is also connected to a press; the cylinder 11 drives the press to press the top of the placement platform 24 to prevent the bending force of the hook from spreading along the vertical direction of the hook during the bending process, causing the hook to tilt;

[0035] As a supplement: an airbag 4 is installed in a vertical position at the bottom of the presser, and vents are opened at both ends of the airbag 4. During the downward movement of the pressing head 12, the presser will squeeze the airbag 4. Since both ends of the airbag 4 are open, the inside is circulated with the outside air. By squeezing the center position of the airbag 4, the internal gas will flow out from the openings at both ends of the airbag 4, blowing air on the hook during bending, preventing burrs and flying chips on its surface from being adsorbed to its surface during the bending process, resulting in the burrs causing wear on the surface of the hook when the hook is squeezed.

[0036] The detection assembly 5 consists of a detection camera 51 and a support 52; the detection camera 51 is slidably connected to the support 52, and a spring is provided at the bottom of the support 52; when the detection camera 51 detects the bent hook to prevent cracks on its surface, the clamp 23 still squeezes the bent hook to prevent further damage to the hook. At the same time, the support 52 limits the height of the detection camera 51 to prevent its viewing angle from leaving the placement platform 24. At the same time, the support 52 is elastically set, and when the angle of the detection camera 51 needs to be adjusted, it can be raised and lowered accordingly.

[0037] Working principle:

[0038] The hook is placed on the placement table 24 so that the hook is wrapped around the two groups of cylinders of the placement table 24. At the same time, by starting the rotating motor 21, the two groups of clamping blocks 23 are driven to move toward the placement table 24 at the same time, which plays a top role for the hook wrapped on the placement table 24 and slowly squeezes its bent part to prevent the hook from breaking due to excessive speed. By pushing the sliding push rod 31, the sliding push rod 31 can be rotated along the positioning rod 32. At the same time, the end of the sliding push rod 31 can be pushed to the end of the clamping block 23 so that when the sliding push rod 31 moves, its end can drive the end of the clamping block 23 to rotate slightly left and right, so that the squeezing direction of the clamping block 23 on the hook is changed, which is convenient for changing the angle of the bending part of the hook. At the same time, the cylinder 11 is started, and the presser is driven by the cylinder 11 to press the top of the placement table 24 to prevent the bending force of the hook from spreading along the vertical direction of the hook during the bending process, causing the hook to tilt.
