Description

Technical Field

[0001] This invention belongs to the field of automotive parts manufacturing technology, specifically a stamping device for processing automotive brackets. Background Technology

[0002] Currently, the production of automotive driveshaft brackets requires the use of a stamping device to stamp flat sheet metal into an arc-shaped structure that matches the driveshaft. The arc-shaped bracket body provides stable support for the driveshaft, thereby ensuring the stability of the driveshaft during rotation.

[0003] In existing technologies, continuous stamping of automotive brackets mostly involves manually placing a flat sheet metal on the upper part of the die, and then using a drive mechanism to move the punch downwards. As the punch moves downwards, it presses the flat sheet metal into the die, thus completing the stamping process. After stamping, the drive mechanism moves the punch upwards, and at the same time, the ejector mechanism ejects the arc-shaped bracket body that is stuck inside the die. Then, the operator removes the ejected arc-shaped bracket body and places a new sheet metal. It can be seen that the existing continuous stamping of automotive brackets requires too much manual intervention, which is not conducive to the continuous and efficient stamping of automotive brackets. Summary of the Invention

A magnet is provided at the bottom of the die seat. A connecting rod is fixedly provided at the upper part of the die seat. A first sliding rod is fixedly provided on the side wall of the connecting rod. The end of the first sliding rod away from the connecting rod extends into the interior of the transverse sliding groove and slides in cooperation with the transverse sliding groove. A bottom rod is fixedly provided at the upper end of the connecting rod. A first push rod and a second push rod are respectively fixedly provided at the two ends of the upper part of the bottom rod, which are vertically oppositely distributed.

[0015] The drive assembly includes a rotating shaft, a rotating rod, a motor, and a rotating wheel. The motor is fixedly mounted on the side wall of the bracket plate. One end of the rotating shaft is connected to the output end of the motor, and the other end is connected to the rotating rod. The end of the rotating rod away from the rotating shaft is rotatably connected to the rotating wheel. The rotating wheel extends between the first push rod and the second push rod.

[0016] As a further improvement of the present invention: the punch seat has a vertically distributed first slide rail inside, one end of the first slide rail extends to the upper surface of the punch seat, a first push rod is movably inserted inside the first slide rail, and a first elastic element is provided inside the first slide rail to provide elastic support for the first push rod.

[0017] As a further improvement of the present invention: a second vertically distributed slide rail is provided inside the die holder, one end of the second slide rail extends to the inner wall of the arc-shaped stamping opening, a second push rod is slidably disposed inside the second slide rail, and a second elastic element is provided inside the second slide rail for providing elastic tension to the second push rod.

[0018] The side wall of the die holder has a slot communicating with the second slide rail, and a second slide rod is fixedly installed on the side wall of the second push rod. The end of the second slide rod away from the second push rod extends from the slot to the outside of the die holder.

[0019] The unloading assembly includes a V-shaped plate, which is fixedly installed on the side wall of the support plate.

[0020] As a further improvement of the present invention: a discharge chute is provided on the upper part of the stamping platform at the position between the punch seat and the feeding area.

One end of the third elastic element is connected to the bottom of the top support slider, and the other end is connected to the inner bottom wall of the vertical groove, for providing elastic support to the top support slider.

[0022] As a further improvement of the present invention: the first elastic element, the second elastic element and the third elastic element are springs or metal sheets.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] In this embodiment of the invention, when continuous stamping of an automotive bracket is required, a set of sheet metal constituting the automotive bracket can be placed on a placement area. Then, a drive assembly moves a die holder above the placement area, allowing the die holder to carry the sheet metal. After the die holder carries the sheet metal, the drive assembly moves the die holder towards a punch. When the die holder carries the sheet metal above the punch, the die holder and punch cooperate to stamp the sheet metal, forming an arc-shaped bracket body. Subsequently, the drive assembly moves the die holder towards the placement area, simultaneously moving the arc-shaped bracket body. When the die holder carries the arc-shaped bracket body between the punch and the unloading area, an unloading assembly removes the arc-shaped bracket body carried by the die holder. The die holder moves unloaded above the unloading area to carry the sheet metal placed there again. After the die holder carries the sheet metal again, the drive assembly moves the die holder towards the punch to move the sheet metal above the punch again, enabling the sheet metal to be stamped again. After the sheet metal is stamped into an arc-shaped support body, the drive assembly moves the die holder towards the unloading area again. The unloading assembly removes the arc-shaped support body carried by the die holder, and the die holder moves unloaded again above the unloading area. This cycle repeats, enabling continuous automatic stamping of automotive brackets. Compared with existing technologies, this method enables continuous automatic stamping of automotive brackets without much manual intervention, resulting in better stamping effect and higher stamping efficiency.

Detailed Implementation

[0032] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0033] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] Please see Figure 1 , Figure 2 as well as Figure 3This embodiment provides a stamping device for processing automotive brackets, including a stamping table 10, a punch holder 20, a die holder 30, a drive assembly 50, and an unloading assembly 60. A support plate 101 is fixedly mounted on the upper part of the stamping table 10. The punch holder 20 is fixedly installed at one end of the upper part of the stamping table 10. A feeding area is provided at the upper end of the stamping table 10 away from the punch holder 20. The die holder 30 is movably disposed on one side of the support plate 101. The drive assembly 50 is mounted on the support plate 101 and is used to drive the die holder 30 to move within the feeding area. The feeding area reciprocates between the punch seat 20 and the die seat 30. When the die seat 30 moves from the feeding area to the punch seat 20, it carries the sheet metal to be stamped. When the die seat 30 moves from the punch seat 20 to the feeding area, it carries the stamped arc-shaped support body. The unloading assembly 60 is installed on the side wall of the support plate 101. When the die seat 30 carries the stamped arc-shaped support body to the space between the punch seat 20 and the feeding area, the unloading assembly 60 removes the arc-shaped support body carried by the die seat 30.

[0035] When continuous stamping is required for automotive brackets, a set of sheet metal constituting the bracket can be placed on the placement area. Then, the drive assembly 50 moves the die holder 30 above the placement area, allowing the die holder 30 to carry the sheet metal. After the die holder 30 carries the sheet metal, the drive assembly 50 moves the die holder 30 towards the punch holder 20. When the die holder 30 carrying the sheet metal moves above the punch holder 20, the die holder 30 and the punch holder 20 cooperate to stamp the sheet metal, forming an arc-shaped bracket body. Subsequently, the drive assembly 50 moves the die holder 30 towards the placement area, at which time the die holder 30 moves synchronously with the arc-shaped bracket body. When the die holder 30 carrying the arc-shaped bracket body moves between the punch holder 20 and the unloading area... The unloading assembly 60 removes the arc-shaped support body carried by the die holder 30. Then, the die holder 30 moves unloaded to the top of the unloading area to carry the sheet metal placed in the unloading area again. After the die holder 30 carries the sheet metal again, the drive assembly 50 drives the die holder 30 to move towards the punch 20 to move the sheet metal above the punch 20 again, realizing the stamping of the sheet metal again. After the sheet metal is stamped into an arc-shaped support body again, the drive assembly 50 drives the die holder 30 to move towards the unloading area again. The unloading assembly 60 removes the subsequent arc-shaped support body carried by the die holder 30 again. The die holder 30 moves unloaded to the top of the unloading area again. This cycle repeats, realizing the continuous automatic stamping and forming of the car bracket.

[0036] Please see Figure 1 , Figure 2 as well as Figure 3In one embodiment, the sidewall of the support plate 101 is provided with a transverse sliding groove 103, and vertical sliding grooves 104 are provided at opposite ends of the transverse sliding groove 103. Each of the two sets of vertical sliding grooves 104 is provided with an elastic support assembly 40. The outer wall of the punch seat 20 is provided with an arc-shaped surface. The bottom of the die seat 30 is provided with an arc-shaped stamping opening 301 adapted to the arc-shaped surface. A magnet is provided at the bottom of the die seat 30. A connecting rod 302 is fixedly provided on the upper part of the die seat 30. A first sliding rod 303 is fixedly provided on the sidewall of the connecting rod 302. The end of the first sliding rod 303 away from the connecting rod 302 extends into the transverse sliding groove 103 and connects with the transverse sliding groove 104. 3. Sliding fit: A base rod 304 is fixedly installed at the upper end of the connecting rod 302. A first push rod 305 and a second push rod 306 are respectively fixedly installed at the two ends of the upper part of the base rod 304. The drive assembly 50 includes a rotating shaft 501, a rotating rod 502, a motor 503, and a rotating wheel 504. The motor 503 is fixedly installed on the side wall of the bracket plate 101. One end of the rotating shaft 501 is connected to the output end of the motor 503, and the other end is connected to the rotating rod 502. The end of the rotating rod 502 away from the rotating shaft 501 is rotatably connected to the rotating wheel 504. The rotating wheel 504 extends between the first push rod 305 and the second push rod 306.

[0037] The motor 503 drives the rotating shaft 501 to rotate in both directions, which in turn drives the connecting rod 502 and the rotating wheel 504 to rotate in both directions. When the rotating wheel 504 rotates in the forward direction, it acts on the side wall of the first push rod 305, thereby pushing the first push rod 305 to push the first slide rod 303 to slide to the right along the transverse slide groove 104. When the first slide rod 303 slides to the right along the transverse slide groove 104, it can drive the connecting rod 302 and the die holder 30 as a whole to move from the punch holder 20 towards the feeding area. When the rotating rod 502 rotates in the forward direction to a horizontal state, the rotating wheel 504 acts on the upper surface of the bottom rod 304, and the first slide rod 303 slides to the right end of the transverse slide groove 103. The elastic support component 40 located in the right vertical slide groove 104 lifts the first slide rod 303. Provided with elastic support, the die holder 30 moves to a position directly above the unloading area. Subsequently, as the rotating rod 502 and the rotating wheel 504 rotate further in the forward direction, the rotating wheel 504 applies downward pressure to the bottom rod 304, causing the first slide rod 303 to slide down along the right vertical groove 104. Simultaneously, the connecting rod 302 and the die holder 30 move vertically downwards. The magnet at the bottom of the die holder 30 acts on the sheet metal in the unloading area, thereby attracting the sheet metal. After the magnet attracts the sheet metal, the motor 503 drives the rotating shaft 501, the rotating rod 502, and the rotating wheel 503 to rotate in the opposite direction. When the rotating wheel 503 rotates in the opposite direction, it moves upwards relative to the bottom rod 304. The elastic support assembly 40 in the right vertical groove 104 pushes the first slide rod 303. The first slide rod 303 slides upward along the right vertical slide groove 104, thereby driving the connecting rod 302 and the die holder 30 to move upward. When the die holder 30 moves upward, it drives the sheet metal upward. When the rotating rod 302 rotates to the horizontal state again, the rotating wheel 504 separates from the side wall of the first push rod 305. As the rotating wheel 504 continues to rotate in the opposite direction, the rotating wheel 504 acts on the side wall of the second push rod 306, thereby pushing the second push rod 306 to make the first slide rod 303 slide to the left along the transverse slide groove 103. The first slide rod 303 drives the connecting rod 302 and the die holder 30 to move from the feeding area to the punch holder 20. During this process, the die holder 30 carries the sheet metal. When the die holder 30 moves to the position directly above the punch holder 20, The first slide rod 303 slides to the left end of the horizontal slide groove 103, the rotating rod 302 rotates to the horizontal state again, the rotating wheel 504 acts on the upper surface of the bottom rod 304 again, and the elastic support component 40 located inside the left vertical slide groove 104 provides elastic support for the first slide rod 303. After that, as the rotating wheel 504 rotates further in the opposite direction, the rotating wheel 504 applies downward pressure to the bottom rod 304 again, causing the first slide rod 303 to slide down along the inside of the left vertical slide groove 104, thereby driving the connecting rod 302 and the die seat 30 to move vertically downward. When the die seat 30 moves vertically downward, the sheet metal acts on the arc surface of the upper part of the punch seat 20. The sheet metal is pressed and adaptably bends into the arc-shaped punch 301, thereby forming an arc-shaped support body.After the sheet metal is stamped into an arc-shaped support body, the motor 503 drives the rotating shaft 501, rotating rod 502, and rotating wheel 504 to move forward again. When the rotating wheel 504 rotates forward, it moves upward relative to the bottom rod 304. The elastic support component 40 in the left vertical slide groove 104 pushes the first slide rod 303, causing the first slide rod 303 to slide upward along the inside of the left vertical slide groove 104, thereby driving the connecting rod 302 and the die holder 30 to move upward. When the die holder 30 moves upward, the arc-shaped support body is embedded in the arc-shaped stamping opening. Inside 301, the die holder 30 can synchronously move the arc-shaped support body upwards. When the first slide rod 303 slides upwards to the left end of the transverse slide groove 103, the rotating wheel 504 separates from the upper surface of the bottom rod 304. As the rotating wheel 504 rotates further in the forward direction, it acts on the side wall of the first push rod 305 again, thereby pushing the first push rod 305 to make the first slide rod 303 slide to the right along the interior of the transverse slide groove 103. The first slide rod 303 drives the connecting rod 302 and the die holder 30 to move to the right again.

[0038] After the die holder 30 and the punch holder 20 cooperate to stamp the sheet metal into an arc-shaped support body, as the die holder 30 moves upward, the arc-shaped support body is prone to become stuck on the punch holder 20 due to friction. At this time, the die holder 30 cannot smoothly carry the arc-shaped support body, thus affecting the subsequent normal unloading. To avoid this phenomenon, please refer to... Figure 4 as well as Figure 5 In one embodiment, the punch seat 20 has a vertically distributed first slide rail 201 inside, one end of the first slide rail 201 extends to the upper surface of the punch seat 20, a first push rod 202 is movably inserted inside the first slide rail 201, and a first elastic member 203 is provided inside the first slide rail 201 for providing elastic support to the first push rod 202.

[0039] Initially, the first ejector pin 202 extends to the top of the punch seat 20 under the elastic support of the first elastic element 203. When the die seat 30 carries the sheet metal down from the position above the punch seat 20, the bottom of the sheet metal acts on the first ejector pin 202, thereby driving the first ejector pin 202 to slide down along the inside of the first slide rail 201. The first elastic element 203 is adaptively compressed. After the sheet metal is stamped into an arc-shaped support body, as the die seat 30 moves up, the first elastic element 203 pushes the first ejector pin 202, causing the first ejector pin 202 to slide up along the inside of the first slide rail 201, thereby pushing the arc-shaped support body away from the outside of the punch seat 20, so that the arc-shaped support body can be smoothly embedded in the arc-shaped stamping opening 301, so that the die seat 30 can smoothly carry the arc-shaped support body.

[0040] Please see Figure 2 , Figure 4 as well as Figure 5In one embodiment, the die holder 30 has a vertically distributed second slide rail 307 inside, one end of the second slide rail 307 extends to the inner wall of the arc-shaped stamping port 301, a second push rod 310 is slidably disposed inside the second slide rail 307, and a second elastic element 308 is disposed inside the second slide rail 310 for providing elastic tension to the second push rod 310. The side wall of the die holder 30 has a slot 311 communicating with the second slide rail 307, and a second slide rod 309 is fixedly disposed on the side wall of the second push rod 310. The end of the second slide rod 309 away from the second push rod 310 extends from the slot 311 to the outside of the die holder 30. The unloading assembly 60 includes a V-shaped plate, and the V-shaped plate is fixedly installed on the side wall of the support plate 101.

[0041] When the first slide rod 303 slides to the right along the transverse slide groove 103, thereby driving the connecting rod 302 and the die holder 30 to move from the punch holder 20 towards the unloading area, the stamped arc-shaped support body is embedded in the arc-shaped stamping opening 301 and moves synchronously with the die holder 30. When the die holder 30 moves to the position between the punch holder 20 and the unloading area, the second slide rod 309 acts on the bottom wall of the V-shaped plate and slides down along the bottom wall of the V-shaped plate. The second slide rod 309 slides down along the inside of the slot 311 and drives the second ejector rod 310 to slide down along the inside of the second slide rail 307. When the second ejector rod 310 slides down, its lower end extends into the arc-shaped stamping opening 301, thereby embedding the arc-shaped support body in the arc-shaped plate. The arc-shaped support body inside the pressure port 301 is pushed away. After being pushed away, the arc-shaped support body automatically falls to the upper part of the stamping table 10, located between the punch seat 20 and the feeding area, so that the die seat 30 can remain unloaded after moving above the feeding area, and then continue to carry subsequent sheet metal. After the arc-shaped support body is pushed away from the inside of the arc-shaped stamping port 301, the second slide rod 309 passes over the lowest end of the bottom wall of the V-shaped plate. Then, the second elastic element 308 pulls the second push rod 310, causing the second push rod 310 to slide upward along the inside of the second slide rail 307, thereby driving the second slide rod 309 to slide upward along the inside of the slot 311, realizing the reset of the second push rod 310 and the second slide rod 309.

[0042] Please see Figure 1 as well as Figure 2 In one embodiment, a discharge chute 102 is provided on the upper part of the stamping table 10 at the position between the punch seat 20 and the feeding area.

[0043] After the arc-shaped support body is pushed away from the inside of the arc-shaped stamping port 301, it can fall into the inside of the discharge chute 102, and then slide down from the inside of the discharge chute 102, and then be automatically removed from the top of the stamping table 10.

[0044] Please see Figure 1 as well as Figure 6In one embodiment, the elastic support assembly 40 includes a top support slider 401 and a third elastic element 402. The top support slider 401 is slidably disposed inside the vertical groove 104. One end of the third elastic element 402 is connected to the bottom of the top support slider 401, and the other end is connected to the inner bottom wall of the vertical groove 104, for providing elastic support to the top support slider 401.

[0045] When the rotating wheel 504 applies pressure to the upper surface of the base rod 304, the first sliding rod 303 pushes the top support slider 401 to overcome the elastic force of the third elastic element 402 and slide down along the interior of the vertical groove 104. At the same time, the first sliding rod 303 slides down along the interior of the vertical groove 104. When the rotating wheel 504 changes its rotation direction and moves upward relative to the base rod 304, the third elastic element 402 pushes the top support slider 401 to slide upward along the interior of the vertical groove 104, thereby resetting the top support slider 401.

[0046] In one embodiment, the first elastic element 203, the second elastic element 308, and the third elastic element 402 can be springs or metal sheets, and there is no limitation here.

[0047] In this embodiment of the invention, when continuous stamping is required for an automotive bracket, a set of sheet metal constituting the automotive bracket can be placed on a placement area. Then, the drive assembly 50 drives the die holder 30 to move above the placement area, so that the die holder 30 carries the sheet metal. After the die holder 30 carries the sheet metal, the drive assembly 50 drives the die holder 30 to move towards the punch holder 20. When the die holder 30 carries the sheet metal above the punch holder 20, the die holder 30 and the punch holder 20 cooperate to stamp the sheet metal, so that the sheet metal forms an arc-shaped bracket body. Subsequently, the drive assembly 50 drives the die holder 30 to move towards the placement area. At this time, the die holder 30 drives the arc-shaped bracket body to move synchronously. When the die holder 30 carries the arc-shaped bracket body to the space between the punch holder 20 and the unloading area, the unloading assembly 60 performs unloading on the arc-shaped bracket body carried by the die holder 30. The die holder 30 is unloaded and then moves to the top of the unloading area to carry the sheet metal placed there again. After the die holder 30 carries the sheet metal again, the drive assembly 50 moves the die holder 30 towards the punch 20 to move the sheet metal above the punch 20 again for re-stamping. After the sheet metal is stamped into an arc-shaped support body, the drive assembly 50 moves the die holder 30 towards the unloading area again, and the unloading assembly 60 unloads the arc-shaped support body carried by the die holder 30. The die holder 30 then moves to the top of the unloading area again. This cycle repeats, enabling continuous automatic stamping of the car bracket. Compared with existing technologies, this method enables continuous automatic stamping of the car bracket, requiring minimal manual intervention during the stamping process, and offers advantages such as good stamping effect and high stamping efficiency.

[0048] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
