Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, specifically a combined automotive parts stamping die. Background Technology

[0002] Energy-absorbing boxes are important components in automobiles, installed between the front bumper beam and the front longitudinal beam. In the event of a collision, the energy-absorbing box collapses to absorb energy, cushioning some of the impact and protecting the safety of passengers. In minor collisions, the energy-absorbing box can also absorb energy through its collapse, protecting other parts of the vehicle and reducing repair costs for the owner.

[0003] The structure of the car energy-absorbing box is as follows Figure 10 and Figure 11 As shown, the upper surface of the energy-absorbing box is inclined, and the interior contains multiple independently distributed chambers. There are multiple holes that need to be processed around the outer wall. Therefore, it is necessary to punch holes on multiple sides of the energy-absorbing box. However, the existing punching equipment on the market often adopts single-sided punching operation, punching holes on multiple sides of the energy-absorbing box in multiple steps, which results in low punching efficiency.

[0004] Therefore, the applicant has developed a new technical solution in the actual production process to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a combined automotive parts stamping die, which has the advantage of simultaneously punching multiple sides of the energy-absorbing box.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This invention provides a combined automotive parts stamping die, including a moving die box and a fixed die box for positioning an energy-absorbing box and located on the inner and outer sides of the energy-absorbing box respectively, and a power mechanism for driving the moving die box to rise and fall. The power mechanism drives the moving die box to move vertically out of or into the fixed die box.

[0008] It also includes several punching mechanisms distributed around the periphery of the fixed mold box. Each of the punching mechanisms punches the energy-absorbing box from multiple sides through the fixed mold box and the moving mold box. After the energy-absorbing box is punched, the power mechanism drives the moving mold box to move out of the fixed mold box.

[0009] It also includes a feeding mechanism and a discharging mechanism. The feeding mechanism is located on one side of the fixed mold box and is used to push a single energy-absorbing box to the upper opening of the fixed mold box. The discharging mechanism is located below the fixed mold box and is used to move the punched energy-absorbing box downward out of the fixed mold box. When the punched energy-absorbing box moves downward out of the fixed mold box, the energy-absorbing box to be processed at the upper opening of the fixed mold box falls into the fixed mold box under the action of gravity.

[0010] By adopting the above technical solution, the feeding mechanism pushes the energy-absorbing box to be punched to the upper opening of the fixed mold box. The energy-absorbing box to be punched tends to descend due to gravity. At this time, the energy-absorbing box to be punched is supported by the energy-absorbing box that has been punched previously. As the unloading mechanism moves the energy-absorbing box that has been punched previously out of the fixed mold box, the energy-absorbing box to be processed is also gradually moved into the fixed mold box. The power mechanism drives the moving mold box to be vertically inserted into the fixed mold box, which makes it easier for each punching mechanism to punch the energy-absorbing box on multiple sides at the same time through the fixed mold box and the moving mold box, thereby improving the punching efficiency.

[0011] Preferably, the system includes a base plate for fixing the fixed mold box. The power mechanism and the punching mechanism are both mounted on the base plate. The unloading mechanism includes an exit hole on the base plate for the energy-absorbing box inside the fixed mold box to move downward out of the fixed mold box. The lower end face of the base plate is provided with a limiting member to restrict the position of the energy-absorbing box inside the fixed mold box. After the energy-absorbing box is punched, the power mechanism is equipped with a detachment member to prevent the energy-absorbing box from moving out of the fixed mold box with the moving mold box.

[0012] Preferably, the power mechanism includes a mounting plate disposed on the base plate and extending at one end to the top of the moving mold box, and fixed plates for mounting the moving mold box are distributed above and below the mounting plate, and a power source for driving the fixed plates to move vertically back and forth is provided on the mounting plate;

[0013] The release mechanism includes release plates connected to the lower end face of the fixed plate by various compression springs. The release plates are distributed around the outer wall of the moving mold box and a push plate is provided inside the release plate to push the upper end of the energy-absorbing box downward. The lower end face of the fixed plate is provided with a limiting rod passing through each compression spring. When the moving mold box is inserted into the fixed mold box until the limiting mechanism is reached, the lower end of the limiting rod abuts against the upper end face of the release plate and the compression spring is in a compressed state.

[0014] Preferably, the base plate is supported off the ground by several support plates, and a discharge conveyor belt is provided below the base plate to transport the energy-absorbing box that is removed from the removal hole. The discharge conveyor belt transports the energy-absorbing box to one side of the base plate. The limiting member is equipped with an inclined plate, which pushes the energy-absorbing box onto the discharge conveyor belt after it is removed from the removal hole.

[0015] Preferably, the limiting member includes a limiting plate slidably connected to the lower end face of the base plate and a driving source for driving the limiting plate to reciprocate. The limiting plate is provided with an insertion hole for the lower end of the moving mold box to be inserted. The limiting plate is provided with inclined pushing surfaces on the side away from the driving source. When the limiting plate covers the removal hole, the pushing surfaces separate the energy-absorbing box to be punched from the energy-absorbing box that has been punched, and cause the lower end of the energy-absorbing box to be punched to move upward into the fixed mold box.

[0016] Preferably, the inclined plate is disposed on the lower end face of the limiting plate and there is a gap between it and the pushing surface, and the inclined plate is distributed on the inclined surface of the energy-absorbing box that is moved out by the feeding mechanism.

[0017] Preferably, the discharge conveyor belt is provided with a receiving frame, which receives the energy-absorbing box removed from the removal hole, and there is a gap between the receiving frame and the discharge conveyor belt for the energy-absorbing box to be removed after being tilted.

[0018] Preferably, the feeding mechanism includes a storage conveyor belt and a pusher disposed on the base plate and located on one side of the fixed mold box. The upper surface of the fixed mold box is provided with a baffle that keeps the energy-absorbing boxes vertically distributed. After the storage conveyor belt transports each energy-absorbing box to one side of the upper opening of the fixed mold box, the pusher pushes the energy-absorbing box located on one side of the upper opening of the fixed mold box into the upper opening of the fixed mold box and makes the energy-absorbing box abut against the baffle.

[0019] Preferably, the material storage conveyor belt is provided with a guide plate. When the pusher pushes the energy-absorbing box to move towards the upper opening of the fixed mold box, one side of the outer wall of the energy-absorbing box moves along the guide plate.

[0020] Preferably, each of the punching mechanisms includes an electric cylinder 1 mounted on a base plate, and the piston rod of the electric cylinder 1 is provided with a punch that enters the fixed mold box and the moving mold box.

[0021] The beneficial effects of this invention are as follows: the feeding mechanism pushes the energy-absorbing box to be punched to the upper opening of the fixed mold box. The energy-absorbing box to be punched tends to descend due to gravity. At this time, the energy-absorbing box to be punched is supported by the energy-absorbing box that has been punched previously. As the unloading mechanism moves the energy-absorbing box that has been punched previously out of the fixed mold box, the energy-absorbing box to be processed is also gradually moved into the fixed mold box. The power mechanism drives the moving mold box to be vertically inserted into the fixed mold box, which makes it easier for each punching mechanism to punch the energy-absorbing box on multiple sides simultaneously through the fixed mold box and the moving mold box, thereby improving the punching efficiency.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figure 10 and Figure 11The energy-absorbing box 2 is a rectangular frame with openings at both the top and bottom. The upper surface of the energy-absorbing box 2 is a sloping surface 21. The inner wall is provided with a cross-shaped partition plate 22. The upper and lower ends of the partition plate 22 extend to the upper and lower openings of the energy-absorbing box 2, respectively. The partition plate 22 divides the interior of the energy-absorbing box 2 into four independently distributed and parallel chambers. The outer wall of the energy-absorbing box 2 has multiple holes that need to be processed.

[0037] A type of combined automotive parts stamping die, such as Figure 1 and Figure 2 and Figures 5-7 The system includes a base plate 1 and a movable mold box 11 and a fixed mold box 12, which are used to position the energy-absorbing box 2 and are located on the inner and outer sides of the energy-absorbing box 2, respectively. The fixed mold box 12 is open at both its top and bottom ends. After the energy-absorbing box 2 enters the fixed mold box 12, the height of the energy-absorbing box 2 is distributed along the height of the fixed mold box 12, and the uppermost end of the inclined surface 21 of the energy-absorbing box 2 is flush with the upper end surface of the fixed mold box 12. The lower end of the fixed mold box 12 is fixed to the base plate 1. The base plate 1 is equipped with a power mechanism for driving the movable mold box 11 to move up and down. The power mechanism drives the movable mold box 11 to move vertically out of or into the fixed mold box 12, that is, to move out of or into each cavity of the energy-absorbing box 2 located within the fixed mold box 12. Figure 10 As shown, the energy-absorbing box 2 has four independent chambers, therefore the moving mold box 11 consists of four independently distributed boxes corresponding to the chambers of each energy-absorbing box 2 (e.g., Figure 7 At this time, the moving mold box 11 and the fixed mold box 12 form a combined mold.

[0038] like Figure 3 It also includes several punching mechanisms distributed around the periphery of the fixed mold box 12. Each punching mechanism is fixed on the base plate 1 and the distribution direction is according to the holes that need to be punched on the outer wall of the energy-absorbing box 2. Each punching mechanism punches the energy-absorbing box 2 from multiple sides through the fixed mold box 12 and the moving mold box 11. After punching the energy-absorbing box 2, the power mechanism drives the moving mold box 11 to move out of the fixed mold box 12. Each punching mechanism includes an electric cylinder 13 set on the base plate 1. The piston rod of the electric cylinder 13 is provided with a punch 131 that enters the fixed mold box 12 and the moving mold box 11. The fixed mold box 12 and the moving mold box 11 are provided with punching holes corresponding to the distribution of each punch 131. The punching holes allow the punch 131 to move into the fixed mold box 12 and the moving mold box 11.

[0039] like Figures 1-4 It also includes a feeding mechanism and a discharging mechanism. The feeding mechanism is located on one side of the fixed mold box 12 and is used to push a single energy-absorbing box 2 to the upper opening of the fixed mold box 12. The discharging mechanism is located below the fixed mold box 12 and is used to move the punched energy-absorbing box 2 out of the fixed mold box 12 downwards. The discharging mechanism also supports and limits the energy-absorbing box 2 inside the fixed mold box 12. When the punched energy-absorbing box 2 moves downwards out of the fixed mold box 12, the energy-absorbing box 2 to be processed at the upper opening of the fixed mold box 12 falls into the fixed mold box 12 under the action of gravity.

[0040] like Figures 1-4 The feeding mechanism pushes the energy-absorbing box 2 to be punched to the upper opening of the fixed mold box 12. The energy-absorbing box 2 to be punched tends to descend due to gravity. At this time, the energy-absorbing box 2 to be punched is supported by the energy-absorbing box 2 that has been punched previously. As the unloading mechanism moves the energy-absorbing box 2 that has been punched previously out of the fixed mold box 12, the energy-absorbing box 2 to be processed is also gradually moved into the fixed mold box 12. The power mechanism drives the moving mold box 11 to be vertically inserted into the fixed mold box 12. At this time, the outer wall of the energy-absorbing box 2 is limited by the fixed mold box 12, the inner wall of the energy-absorbing box 2 is limited by the moving mold box 11, and the lower end is limited by the unloading mechanism. This makes it easier for each punching mechanism to punch the energy-absorbing box 2 on multiple sides simultaneously through the fixed mold box 12 and the moving mold box 11, thereby improving the punching efficiency.

[0041] like Figures 1-3 The power mechanism is set on the base plate 1, and the power mechanism includes an L-shaped mounting plate 14 set on the base plate 1. The vertical end of the mounting plate 14 is fixedly connected to the base plate 1, and the horizontal side extends to the top of the moving mold box 11. The mounting plate 141 for mounting the moving mold box 11 is distributed below the horizontal side of the mounting plate 14. Each box of the moving mold box 11 is mounted on the lower end surface of the mounting plate 141. The mounting plate 14 is provided with a power source for driving the mounting plate 141 to move vertically back and forth. The power source is an electric cylinder 142. The electric cylinder 142 is set on the upper end surface of the mounting plate 14, and the piston rod of the electric cylinder 142 extends out of the horizontal side of the mounting plate 14 and is fixedly connected to the mounting plate 141. The electric cylinder 142 drives the mounting plate 141 to move back and forth in the vertical direction.

[0042] like Figures 1-3 In order to improve the stability of the movement of the fixed plate 141, vertically distributed guide rods 143 are provided on the upper surface of the fixed plate 141. The upper end of each guide rod 143 extends through the horizontal side of the mounting plate 14 and is slidably connected to the mounting plate 14.

[0043] like Figure 1 and Figure 2 and Figure 5 and Figure 6 The feeding mechanism includes a material storage conveyor belt 15 mounted on the base plate 1 and located on one side of the fixed mold box 12, and a pushing component. On both sides of the length direction of the material storage conveyor belt 15, limiting plates 151 are provided to restrict the transmission of the energy-absorbing box 2 on the material storage conveyor belt 15. The two limiting plates 151 are distributed on the left and right sides of the length direction of the energy-absorbing box 2, so that the height direction of the energy-absorbing box 2 remains vertically distributed. At this time, the height direction and length direction of the energy-absorbing box 2 are referenced. Figure 1The energy-absorbing box 2 is included; the pushing component includes an electric cylinder 152 mounted on a limiting plate 151. The electric cylinder 152 is located on the limiting plate 151 on the side away from the fixed mold box 12. The piston rod of the electric cylinder 152 extends out of the limiting plate 151, and a pushing plate 153 is provided at the end of the extension to push the energy-absorbing box 2 toward the fixed mold box 12. A groove is provided on the limiting plate 151 for the pushing plate 153 to be inserted, so that when the pushing plate 153 is in the groove, it is flush with the surface of the limiting plate 151, which facilitates pushing the next energy-absorbing box 2. The upper surface of the fixed mold box 12 is provided with a mechanism to facilitate the absorption of energy. The energy-absorbing box 2 maintains the vertically distributed baffles 154. At this time, the baffles 154 are distributed in a U-shape and the opening faces the storage conveyor belt 15. At this time, a limiting plate 151 near the fixed mold box 12 extends to the side near the fixed mold box 12, which does not affect the movement of the energy-absorbing box 2 into the U-shaped baffles 154. After the storage conveyor belt 15 transmits each energy-absorbing box 2 to one side of the upper box opening of the fixed mold box 12, the electric cylinder 3 152 pushes the energy-absorbing box 2 located on one side of the upper box opening of the fixed mold box 12 into the upper box opening of the fixed mold box 12 and makes the outer wall of the energy-absorbing box 2 abut against the baffle 154.

[0044] like Figure 2 and Figure 5 and Figure 6 To increase the stability of pushing the energy-absorbing box 2 towards the fixed mold box 12, a guide plate 155 is provided on the material conveyor belt 15. The guide plate 155 is positioned on one side of the limiting plate 151 where the electric cylinder 152 is located, forming an L-shaped distribution between the guide plate 155 and the limiting plate 151. When the electric cylinder 152 pushes the energy-absorbing box 2 towards the upper opening of the fixed mold box 12, one side of the outer wall of the energy-absorbing box 2 moves along the guide plate 155. The side of the guide plate 155 away from the limiting plate 151 interacts with the U-shaped baffle 1. There is a gap between 54 and it is flush with one side wall of the U-shaped baffle 154, so that when the energy-absorbing box 2 is pushed from the storage conveyor belt 15 to the upper opening of the fixed mold box 12, the energy-absorbing box 2 is guided by the guide plate 155 and the baffle 154, and then completely enters the U-shaped baffle 154. At this time, the outer wall of the energy-absorbing box 2 is flush with the inner wall of the fixed mold box 12 and the outer wall of the energy-absorbing box 2 is supported by the baffle 154 and remains vertical. The lower end of the energy-absorbing box 2 is supported by the energy-absorbing box 2 located inside the fixed mold box 12.

[0045] like Figure 4 and Figure 8 and Figure 9 The feeding mechanism includes a discharge hole 16 on the base plate 1 for the energy-absorbing box 2 inside the fixed mold box 12 to move downward out of the fixed mold box 12. The lower end face of the base plate 1 is provided with a limiting member to restrict the position of the energy-absorbing box 2 inside the fixed mold box 12. After the energy-absorbing box 2 is punched, the power mechanism is equipped with a detachment member to prevent the energy-absorbing box 2 from moving out of the fixed mold box 12 with the moving mold box 11.

[0046] like Figure 5 and Figure 6 and Figure 7 The release mechanism includes release plates 171 connected to the lower end face of the fixed plate 141 by various compression springs 17. The release plates 171 are rectangular frames and distributed around the outer wall of the moving mold box 11. When there is a baffle 154, the release plates 171 are distributed around the outer wall of the baffle 154. The release plates 171 are provided with push plates 172 that push the upper end of the energy-absorbing box 2 downward. The push plates 172 are cross-shaped plates, and their ends are fixed to the inner wall of the release plates 171. The push plates 172 are distributed correspondingly to the partition plates 22 inside the energy-absorbing box 2. At this time, the baffle 154 has a notch 173 for the push plate 172 to move downward to the upper end face of the fixed mold box 12. The lower end face of the fixed plate 141 is provided with a limiting rod 174 that passes through each compression spring 17. When the moving mold box 11 is inserted into the fixed mold box 12 until the limiting member, the lower end of the limiting rod 174 abuts against the upper end face of the release plate 171 and the compression spring 17 is in a compressed state. At this time, the limiting rod 174 restricts the moving mold box 11 from continuing to move downward and plays a positioning role in the downward movement of the moving mold box 11.

[0047] like Figure 1 and Figure 2 The base plate 1 is supported off the ground by several support plates 18. Below the base plate 1 is a discharge conveyor belt 19 that transports the energy-absorbing box 2 that is removed from the removal hole 16. The discharge conveyor belt 19 transports the energy-absorbing box 2 to one side of the base plate 1, making it easy to pick up the energy-absorbing box 2 after punching. The limiting component is equipped with an inclined plate 161. The inclined plate 161 pushes the energy-absorbing box 2 onto the discharge conveyor belt 19 after it is removed from the removal hole 16. The purpose is to reduce the energy-absorbing box 2 from tipping over and falling onto the discharge conveyor belt 19 during the transmission of the energy-absorbing box 2 on the discharge conveyor belt 19.

[0048] like Figure 1 and Figure 2 The discharge conveyor belt 19 and the storage conveyor belt 15 are arranged in an L-shape. One side of the discharge conveyor belt 19 extends out of the bottom plate 1, and the other side is provided with a collection box 162 for collecting waste after punching. The inclined plate 161 guides the waste into the collection box 162.

[0049] like Figure 4 and Figure 8 and Figure 9The limiting component includes a limiting plate 163 slidably connected to the lower end face of the base plate 1 and a driving source for reciprocating movement of the limiting plate 163. The driving source is an electric cylinder 164, which is fixed to the lower end face of the base plate 1, and the piston rod of the electric cylinder 164 is distributed parallel to the transmission direction of the material storage conveyor belt 15. The limiting plate 163 has an insertion hole 165 for the lower end of the moving mold box 11 to be inserted. The insertion hole 165 is a hole that passes through the upper and lower end faces of the limiting plate 163. When the lower end of the limiting rod 174 abuts against the upper end face of the release plate 171, the lower end of the moving mold box 11 enters the insertion hole. The hole 165 is flush with the lower end face of the limiting plate 163. The limiting plate 163 has an inclined push surface 166 on the side away from the drive source. The lower end of the push surface 166 is distributed away from the lower end face of the base plate 1, and the higher end is in contact with the lower end face of the base plate 1. When the limiting plate 163 covers the removal hole 16, the push surface 166 separates the energy absorption box 2 to be punched from the energy absorption box 2 after punching and causes the lower end of the energy absorption box 2 to be punched to move upward into the fixed mold box 12. At this time, the lower end of the energy absorption box 2 to be punched is supported by the lower end face of the limiting plate 163.

[0050] The gap between the upper end face of the discharge conveyor belt 19 and the lower end face of the base plate 1 is gap D. The height of an energy-absorbing box 2 is D1. The vertical distance between the higher and lower height positions of the push surface 166 is D2. D is D1 plus two-thirds of D2.

[0051] like Figure 4 and Figure 8 and Figure 9An inclined plate 161 is disposed on the lower end face of the limiting plate 163 and has a gap with the push surface 166. The purpose is to maintain a gap between the inclined surface 21 and the energy-absorbing box 2 when the push surface 166 pushes the energy-absorbing box 2 to be punched into the fixed mold box 12. One end of the inclined plate 161 is fixed to the limiting plate 163, and the other end extends downward at an angle to directly above the collection box 162. The plate surface of the inclined plate 161 is located directly below the insertion hole 165, which facilitates the collection of waste material after punching that falls out of the insertion hole 165. When the limiting plate 163 opens the removal hole 16, the punched energy-absorbing box 2 moves downward by its own weight and is simultaneously supported by the energy-absorbing box 2 to be punched located at the upper opening of the fixed mold box 12. The downward pressing force causes the punched energy-absorbing box 2 to fall completely out of the removal hole 16. The lower end of the energy-absorbing box 2 to be punched also falls out of the removal hole 16. At this time, the side wall of the inclined plate 161 along the length direction is distributed towards the inclined surface 21 of the energy-absorbing box 2 that is moved out by the feeding mechanism. The push surface 166 is also distributed towards the inclined surface 21 of the energy-absorbing box 2 that is moved out by the feeding mechanism. The push surface 166 is directly facing the lower end of the energy-absorbing box 2 to be punched. When the electric cylinder 164 drives the limiting plate 163 to cover the removal hole 16, the push surface 166 first contacts the lower end of the energy-absorbing box 2 and then generates an upward pushing force on the lower end of the energy-absorbing box 2, so that the lower end of the energy-absorbing box 2 to be punched can enter the fixed mold box 12 and be supported by the limiting plate 163.

[0052] like Figure 4 and Figure 8 and Figure 9 The discharge conveyor belt 19 is provided with a receiving frame 191. The receiving frame 191 is U-shaped and the opening is distributed away from the inclined plate 161. The receiving frame 191 receives the energy-absorbing box 2 that is removed from the removal hole 16. After the energy-absorbing box 2 is removed from the removal hole 16, it enters the receiving frame 191 and is limited by the three side walls of the receiving frame 191. There is a gap between the receiving frame 191 and the discharge conveyor belt 19 for the energy-absorbing box 2 to be removed after being tilted.

[0053] like Figures 1-9 Work steps:

[0054] The first energy-absorbing box 2 entering the fixed mold box 12 is inserted manually, and then automatic feeding can be achieved starting from the second energy-absorbing box 2;

[0055] First, after the first energy-absorbing box 2 is placed into the fixed mold box 12, the limiting plate 163 covers the removal hole 16, so that the lower end of the first energy-absorbing box 2 is supported by the upper end surface of the limiting plate 163, and the upper end is located at the upper opening of the fixed mold box 12.

[0056] In the second step, the electric cylinder 142 drives the fixed plate 141 and the movable mold box 11 on the fixed plate 141 to move vertically into the fixed mold box 12, so that the movable mold box 11 is inserted into the cavity of the first energy-absorbing box 2. After the release plate 171 contacts the upper end face of the fixed mold box 12 and the push plate 172 contacts the upper end face of the fixed mold box 12, as the electric cylinder 142 continues to drive the fixed plate 141 to move towards the fixed mold box 12, the release plate 171 squeezes the compression spring 17. The lower end of the limiting rod 174 gradually approaches the upper end face of the release plate 171 until they abut against each other. At this time, the compression spring 17 is compressed to its shortest state, and the lower end of the movable mold box 11 enters the insertion hole 165. The limiting rod 174 restricts the movable mold box 11 from moving downward and plays a positioning role in the downward movement of the movable mold box 11.

[0057] The third step involves driving the corresponding punches 131 through each electric cylinder 13 to simultaneously enter the fixed mold box 12 and the moving mold box 11 until one end of the punch 131 enters the moving mold box 11. At this point, the punch 131 punches the first energy-absorbing box 2, completing the multi-face punching of the first energy-absorbing box 2, and pushing the punched waste into each moving mold box 11. The lower end of each moving mold box 11 is open and connected to the insertion hole 165, so that the waste can fall onto the inclined plate 161 through the moving mold box 11 and the insertion hole 165, and then be guided into the collection box 162 by the inclined plate 161.

[0058] In the fourth step, the electric cylinder 142 drives the fixed plate 141 to move upward. At this time, due to the presence of the compression spring 17, the moving mold box 11 moves upward with the fixed plate 141 and disengages from the push plate 172 on the plate 171 to generate a downward pushing force on the first energy-absorbing box 2 on the moving mold box 11. This reduces the upward movement of the energy-absorbing box 2 as the moving mold box 11 rises after the stamping is completed, so that the first energy-absorbing box 2 after the punching is completed is retained in the fixed mold box 12.

[0059] In the fifth step, the material conveyor belt 15 transports the second energy-absorbing box 2 to a position that abuts against the guide plate 155, so that the second energy-absorbing box 2 is located on one side of the fixed mold box 12 and the lower end face of the second energy-absorbing box 2 is flush with the upper end face of the fixed mold box 12. The electric cylinder 152 pushes the second energy-absorbing box 2, which is located on one side of the upper opening of the fixed mold box 12, into the upper opening of the fixed mold box 12, so that the outer wall of the second energy-absorbing box 2 abuts against the baffle 154. At this time, the lower end of the second energy-absorbing box 2 abuts against the upper end of the first energy-absorbing box 2, so that the first energy-absorbing box 2 generates a supporting force on the second energy-absorbing box 2.

[0060] In the sixth step, the electric cylinder 164 drives the limiting plate 163 to move away from the removal hole 16 until it is completely moved to the side of the removal hole 16. At this time, the first energy-absorbing box 2 loses the support of the limiting plate 163 and moves downward, and the second energy-absorbing box 2 also moves downward with the first energy-absorbing box 2. During this process, the first energy-absorbing box 2 moves out of the fixed mold box 12, and the second energy-absorbing box 2 enters the fixed mold box 12. When the lower end face of the first energy-absorbing box 2 contacts the discharge conveyor belt 19, the discharge conveyor belt 19 has stopped transmitting, and the lower end face of the second energy-absorbing box 2 also moves out of the removal hole 16.

[0061] In the seventh step, the electric cylinder 164 drives the limiting plate 163 to move closer to the removal hole 16, so that the pushing surface 166 on the limiting plate 163 abuts against the lower end surface of the second energy-absorbing box 2, thereby generating an upward pushing force on the second energy-absorbing box 2. At the same time, as the limiting plate 163 covers the removal hole 16, the inclined plate 161 also gradually abuts against the inclined surface 21 of the first energy-absorbing box 2. Thus, the limiting plate 163 has two functions in the process of covering the removal hole 16. The first function is to push the second energy-absorbing box 2 upward into the fixed mold box 12. The second function is to push the first energy-absorbing box 2 onto the discharge conveyor belt 19 through the side wall of the inclined plate 161.

[0062] Step 8: After the first energy-absorbing box 2 is pushed over, the discharge conveyor belt 19 starts to transport the processed first energy-absorbing box 2 out of the base plate 1.

[0063] The limiting plate 163 provides support to the lower end of the second energy-absorbing box 2, and then the second to eighth steps are repeated in a cyclical manner.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
