Description

Technical Field

[0001] This utility model relates to the field of automotive bracket processing technology, specifically to an automotive bracket stamping die. Background Technology

[0002] Automotive bracket manufacturing refers to the process of transforming raw materials into bracket parts for automotive structures through a series of machining processes. Automotive brackets are an important component of automobiles, typically used to support, fix, or connect other parts, such as engine brackets, chassis brackets, and suspension system brackets, to ensure the stability, safety, and functionality of the automotive structure.

[0003] An existing patent (publication number: CN222519610U) discloses a stamping die for an automotive bracket, including a housing with a hydraulic lifting device fixedly installed at the upper end of the housing; it also includes: two lower dies disposed in cavities at the lower end of the housing, and the lower dies are rotatably connected to the housing via a rotating shaft, the inner cavities of the two lower dies forming the forming cavity of the bracket when they are closed; an upper die disposed above the two lower dies, with a lifting block fixedly installed at the upper end of the upper die; and a transmission box disposed at the rear end of the housing, with a rack plate installed inside the transmission box, and transmission gears rotatably installed on both sides of the lower end of the transmission box, a screw fixedly installed at the front end of the transmission gear, and a push rod installed outside the screw. This invention solves the problem that stamping dies cannot improve production continuity while ensuring stamping stability based on the outer contour of the oil pipe.

[0004] The aforementioned document addresses the issue that stamping dies cannot improve production continuity while ensuring stamping stability, based on the outer contour of the oil pipe. However, due to the two lower dies, after stamping, the workpiece tends to adhere to the curved surface of the upper die, causing it to stick to the upper die. Furthermore, since the two lower dies are located deep inside the outer shell, workers need to extend their arms into the shell when removing the workpiece, which is dangerous and increases the probability of accidents. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a stamping die for an automobile bracket, which has advantages such as easy removal and prevention of workpiece adhesion to the punch, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stamping die for an automobile bracket, comprising a body, wherein a demolding component and an anti-sticking component are provided on the upper surface of the body;

[0007] The demolding assembly includes a base, which is fixedly connected to the upper surface of the machine body. A die is mounted on the upper surface of the base. A sliding member is slidably connected inside the base. A cavity is opened inside the sliding member. Two compression cylinders are installed inside the cavity. Two drain pipes are installed on the outer surface of the base. The other ends of the two drain pipes are fixedly connected to the compression cylinders adjacent to them. A spring is fixedly connected to the bottom of each of the two sliding members. The other ends of the two springs are fixedly connected to the base. The sliding member is slidably connected to the bottom of the die.

[0008] The anti-sticking component includes a punch, and two limiting members are bolted to the outer surface of the punch. The upper surface of the two limiting members is provided with an arc-shaped groove. Two elastic claws are fixedly connected to the outer surface of the die, and the two elastic claws are located below the two arc-shaped grooves.

[0009] The above-mentioned design, which incorporates elastic claws, allows the workpiece attached to the punch to be removed when the punch moves away from the die, effectively preventing the workpiece from sticking to or adsorbing onto the punch surface.

[0010] Furthermore, a hydraulic rod is installed at the upper end of the machine body, and the output end of the hydraulic rod is fixedly connected to the upper surface of the punch.

[0011] With the above scheme, the hydraulic rod can push the punch into the die cavity, and the workpiece inside the die cavity is stamped and formed by the pressure of the punch. The release agent inside the die cavity facilitates subsequent demolding after stamping.

[0012] Furthermore, multiple limiting posts are fixedly connected to the upper surface of the body, and the two limiting members are slidably connected to the limiting posts adjacent to them.

[0013] The above scheme allows for the setting of multiple limiting pins to limit the punch, enabling the punch to rise and fall stably and enter the die for stamping.

[0014] Furthermore, both compression cylinders are slidably connected to an extrusion member inside, both extrusion members are slidably inserted into a sliding member, and both extrusion members are fixedly connected to a second spring at their bottom ends, and the other ends of both second springs are fixedly connected to the compression cylinders adjacent to them.

[0015] The above scheme enables the extruder to squeeze the release agent in the compression cylinder after the punch contacts it, allowing the release agent to be discharged onto the inner wall of the die through the drain pipe, facilitating subsequent demolding of the workpiece.

[0016] Furthermore, both of the outer surfaces of the compression cylinders are fixedly connected to inlet pipes, and both the outer surfaces of the inlet pipes and the outlet pipes are equipped with one-way valves.

[0017] The above scheme allows the inlet pipe to facilitate the extraction of mold release agent from the cavity by the compression cylinder and its delivery to the compression cylinder, while the one-way valve prevents the mold release agent from flowing back.

[0018] Furthermore, two blocks are fixedly connected to the inner bottom wall of the base, and the two blocks are symmetrical to each other.

[0019] The above solution allows the stop block to limit the sliding part, ensuring that the sliding part remains horizontal with the inner bottom wall of the die after it reaches its position, which facilitates subsequent stamping of the workpiece.

[0020] Furthermore, a water injection pipe is fixedly connected to the bottom of the cavity, and a valve is installed on the outer surface of the water injection pipe.

[0021] The above solution allows for the convenient injection of release agent into the cavity via a water injection pipe, while the valve can seal the water injection pipe to prevent leakage of the release agent from the cavity.

[0022] Furthermore, a groove is provided on the back of the base, and the water injection pipe is located inside the groove.

[0023] The above solution allows the slot to be opened so that the water injection pipe can follow the sliding component, thus preventing the water injection pipe from affecting the normal sliding operation of the sliding component.

[0024] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0025] This automotive bracket stamping die, by setting a drain pipe, can spray a release agent onto the inner wall of the die when the punch and the sliding part are in contact, effectively reducing the adhesion between the workpiece and the die and facilitating subsequent demolding operations. At the same time, the cooperative design of the sliding part and the spring 1 allows the workpiece to be pushed out by the pushing force of the spring 1 after stamping, ensuring that the workpiece is smoothly removed from the die. In addition, the ejection process occurs during the separation of the punch and the die, which can achieve slow pushing of the workpiece, avoiding the impact on the safe operation of the operator due to the rapid ejection of the workpiece, and reducing the risk of workpiece damage.

[0026] The design of the elastic claw allows the workpiece attached to the punch to be removed when the punch moves away from the die. This effectively prevents the workpiece from sticking or adhering to the punch surface, avoiding the impact of workpieces on the continuity and efficiency of subsequent stamping operations and improving the automation level of production.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] Please see Figure 1 , Figure 2 and Figure 3 The automotive bracket stamping die in this embodiment includes a body 1, and a demolding component 2 and an anti-sticking component 3 are provided on the upper surface of the body 1.

[0039] Please see Figure 2 , Figure 3 and Figure 4The demolding assembly 2 includes a base 201, which is fixedly connected to the upper surface of the body 1. A die 202 is mounted on the upper surface of the base 201. A sliding member 203 is slidably connected inside the base 201. A cavity 204 is opened inside the sliding member 203, and two compression cylinders 205 are installed inside the cavity 204. Two drain pipes 206 are installed on the outer surface of the base 201. The other ends of the two drain pipes 206 are fixedly connected to the compression cylinders 205 adjacent to them. Springs 207 are fixedly connected to the bottom of the two sliding members 203. The other ends of the two springs 207 are fixedly connected to the base 201. The bottom of the 03 and the sliding part 202 are slidably connected. By setting the drain pipe 206, the release agent can be sprayed onto the inner wall of the die 202 when the punch 301 and the sliding part 203 are in contact, which can effectively reduce the adhesion between the workpiece and the mold and facilitate subsequent demolding operations. At the same time, the cooperation design between the sliding part 203 and the spring 207 can push the workpiece out by the pushing force of the spring 207 after the stamping is completed, ensuring that the workpiece is smoothly removed from the mold. In addition, the ejection process occurs during the separation of the punch 301 and the die 202, which can realize the slow pushing of the workpiece, avoid the impact on the safe operation of the operator due to the rapid ejection of the workpiece, and reduce the risk of workpiece damage.

[0040] Please see Figure 2 , Figure 3 and Figure 4 The anti-sticking component 3 includes a punch 301. Two limiting members 302 are bolted to the outer surface of the punch 301. The upper surface of each limiting member 302 is provided with an arc-shaped groove 303. Two elastic claws 304 are fixedly connected to the outer surface of the die 202. Both elastic claws 304 are made of elastic metal and are located below the two arc-shaped grooves 303. The design of the elastic claws 304 can use the elastic force of the elastic claws 304 to remove the workpiece attached to the punch 301 when the punch 301 is away from the die 202. This effectively prevents the workpiece from sticking or adsorbing to the surface of the punch 301, avoiding the workpiece from sticking to the punch 301 and affecting the continuity and efficiency of subsequent stamping work, thus improving the automation level of production.

[0041] Please see Figure 1 , Figure 2 and Figure 4A hydraulic rod 4 is installed at the upper end of the machine body 1. The output end of the hydraulic rod 4 is fixedly connected to the upper surface of the punch 301. The hydraulic rod 4 can push the punch 301 into the die 202. The workpiece in the die 202 is stamped by the pressure of the punch 301. The release agent in the die 202 facilitates the subsequent demolding after stamping. Multiple limiting posts 5 are fixedly connected to the upper surface of the machine body 1. Both limiting members 302 are slidably connected to the limiting posts 5 that are close to them. The multiple limiting posts 5 can limit the punch 301 through the limiting members 302, so that the punch 301 can rise and fall stably and enter the die 202 for stamping.

[0042] Please see Figure 2 , Figure 3 and Figure 4 Both compression cylinders 205 have slidably connected extrusion components 6 inside. Both extrusion components 6 are slidably inserted into the sliding component 203. The bottom end of both extrusion components 6 is fixedly connected to a spring 7. The other end of both springs 7 is fixedly connected to the compression cylinder 205 adjacent to them. The extrusion components 6 are set so that after the punch 301 contacts the extrusion component 6, the extrusion component 6 can squeeze the mold release agent in the compression cylinder 205, so that the mold release agent can be discharged into the inner wall of the die 202 through the drain pipe 206, which facilitates the subsequent demolding of the workpiece. The outer surfaces of both compression cylinders 205 are fixedly connected to the liquid inlet pipes 8. The outer surfaces of the two liquid inlet pipes 8 and the two drain pipes 206 are equipped with one-way valves 9. The liquid inlet pipes 8 can facilitate the compression cylinder 205 to draw out the mold release agent in the cavity 204 and transport it into the compression cylinder 205. The one-way valves 9 can prevent the mold release agent from flowing back.

[0043] Please see Figure 2 , Figure 3 and Figure 4 Two stops 10 are fixedly connected to the inner bottom wall of the base 201. The two stops 10 are symmetrical and can limit the sliding part 203 so that the sliding part 203 can be in a horizontal state with the inner bottom wall of the die 202 after it is in place, which facilitates the subsequent stamping of the workpiece. A water injection pipe 11 is fixedly connected to the bottom of the cavity 204. A valve 12 is installed on the outer surface of the water injection pipe 11. The water injection pipe 11 can facilitate the injection of release agent into the cavity 204. The valve 12 can close the water injection pipe 11 to prevent the release agent from leaking into the cavity 204. A slot 13 is opened on the back of the base 201. The water injection pipe 11 is located inside the slot 13. The slot 13 can facilitate the sliding of the water injection pipe 11 with the sliding part 203 and prevent the water injection pipe 11 from affecting the normal sliding operation of the sliding part 203.

[0044] In this embodiment, an automotive bracket stamping die is provided with a drain pipe 206. When the punch 301 contacts the sliding member 203, a release agent is sprayed onto the inner wall of the die 202, effectively reducing the adhesion between the workpiece and the die and facilitating subsequent demolding operations. At the same time, the cooperative design of the sliding member 203 and the spring 207 allows the workpiece to be ejected by the pushing force of the spring 207 after stamping, ensuring that the workpiece can be smoothly removed from the die. In addition, the ejection process occurs during the separation of the punch 301 and the die 202, which can achieve slow pushing of the workpiece, avoiding the impact on the safe operation of the operator due to the rapid ejection of the workpiece, and reducing the risk of workpiece damage.

[0045] The design of the elastic claw 304 allows the workpiece attached to the punch 301 to be removed by the elastic force of the claw 304 when the punch 301 is away from the die 202. This effectively prevents the workpiece from sticking or adsorbing onto the surface of the punch 301, thus avoiding the workpiece from sticking to the punch 301 and affecting the continuity and efficiency of subsequent stamping work, and improving the automation level of production.

[0046] It should be noted that the tops of the two elastic claws 304 are both hook-shaped with their ends pointing downwards, the two elastic plates 304 are arranged symmetrically, and both elastic plates 304 are integrally formed from elastic steel.

[0047] The working principle of the above embodiment is as follows: When stamping a workpiece, the workpiece is placed in the die 202, and then the hydraulic rod 4 pushes the punch 301 down. When the die 202 contacts the extruder 6, the extruder 6 can squeeze the release agent in the compression cylinder 205, so that the release agent can enter the drain pipe 206 under pressure, and thus be discharged onto the inner wall of the die 202, which facilitates the subsequent demolding of the workpiece. Subsequently, the top of the elastic claw 304 can enter the arc groove 303. When the extruder 6 is squeezed, it can maintain a horizontal state with the upper surface of the sliding member 203. The sliding member 203 will descend under pressure and contact the stop block 10. At this time, the sliding member 203 can maintain a horizontal state with the inner bottom wall of the die 202, which facilitates the cooperation between the punch 301 and the die 202 for stamping. After stamping is completed, the hydraulic rod 4 pulls the punch 301 away from the die 202. At this time, the elastic claw 304 can enter the arc groove 303. The elastic deformation capability of spring 4 will contact the workpiece when sliding in the arc groove 303. As the punch 301 rises, the elastic claw 304 can separate the workpiece from the punch 301, preventing the workpiece from adhering to the punch 301 and affecting subsequent work. When the punch 301 and the die 202 move away from each other, the deformation force of spring 1 207 can push the sliding member 203 out, preventing the workpiece from adhering to the inner wall of the die 202. In addition, the ejection process occurs during the separation of the punch 301 and the die 202, which can realize the slow pushing of the workpiece, avoid affecting the safe operation of the operator due to the rapid ejection of the workpiece, and reduce the risk of workpiece damage. When the punch 301 and the die 202 are completely separated, the deformation force of spring 2 7 can push the extruder 6 to reset, so that the compression cylinder 205 can be in a negative pressure state, so that the release agent in the cavity 204 can enter the compression cylinder 205 through the liquid inlet pipe 8, which facilitates continuous stamping work.
