Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle production, and specifically to a stamping die for new energy vehicle doors. Background Art

[0002] Stamping is a forming process method that applies external forces to plates, strips, tubes, profiles, etc. by a press and a die, causing them to undergo plastic deformation or separation, so as to obtain workpieces (stamped parts) with the required shapes and sizes. When producing new energy vehicle doors, the plates are often formed into the prototypes of the doors by stamping. The die used in the stamping process is called a stamping die. The stamping die is crucial in the manufacturing industry. It is the key equipment to realize the stamping process and can efficiently and accurately process metal or non-metal materials into parts with the required shapes and sizes. Its quality directly affects the accuracy, quality, and production efficiency of the stamped parts, which is related to the product performance and cost. A stamping die for new energy vehicle doors will be used in the production process of new energy vehicle doors.

[0003] When stamping new energy vehicle doors, the edge of the door will be cut by a trimming die. The trimming die is designed with a cutting edge shape that matches the required edge contour of the door. The stamping equipment drives the trimming die to contact the door and applies pressure to cut the cutting edge into the door material, cutting off the excess edge, so as to obtain the edge dimensions and shapes that meet the design requirements. This method can directly cut off the excess material after stamping and is smoothly connected to the overall shape, automatically completing the edge cutting during continuous stamping, improving production efficiency and quality stability.

[0004] The existing stamping dies for new energy vehicle doors still have the following deficiencies: [1]. When the door is not fully stamped and shaped, the cutting edge of the die starts to contact the plate for cutting. Some of the plates that are cut and then stamped will undergo plastic deformation and produce a certain shrinkage, resulting in a certain shrinkage of the shape of the stamped door, and then causing errors in dimensions, so that the stamping quality is poor or even scrapped; [2]. The blade and the die are an integral whole. After the blade is damaged, the entire die often needs to be replaced, and the customization and purchase of the die are relatively expensive, thus increasing the production cost; [3]. The blade is often exposed, and it is easy for the staff to touch the blade during operations such as taking it, resulting in the staff being scratched by the blade, so it is more dangerous to use. Summary of the Invention

[0005] (I) Technical Problems to be Solved In view of the deficiencies of the prior art, the present invention provides a stamping die for new energy vehicle doors, which solves the problems of dimensional errors caused by stamping and cutting at the same time, high equipment maintenance costs, and easy occurrence of danger during the operation of the staff.

[0006] (2) Technical Solution To achieve the above objectives, the present invention is realized through the following technical solutions: A stamping die for a new energy vehicle door includes a bracket. Four corners of the inner side of the bracket are fixedly connected with guide rods. A moving plate is slidably connected to the surfaces of the four guide rods. A moving die is fixedly connected to the bottom of the moving plate. A fixed die is fixedly connected to the inner bottom of the bracket. A receiving groove is formed at the bottom of the moving die. An installation groove is formed inside the moving die. The bottom of the installation groove communicates with the top of the receiving groove. A cutting mechanism is jointly arranged between the inside of the receiving groove and the installation groove. A controller is fixedly connected to the bottom side of the front surface of the bracket. A hydraulic cylinder is fixedly connected to the top of the bracket. A hydraulic rod extends from the bottom end of the hydraulic cylinder. The bottom end of the hydraulic rod passes through the top wall of the bracket and is fixedly connected to the top of the moving plate. Place the plate on the surface of the fixed die so that the plate covers the stamping cavity. Then, extend the hydraulic rod in the hydraulic cylinder downward. The hydraulic rod drives the moving die under the moving plate to move downward until the displacement sensor monitors that the distance between the fixed die and the moving die is zero, that is, after the moving die contacts the fixed die, cut the excess plate through the cutting mechanism. After cutting, the hydraulic rod drives the moving die to move upward to return to the original position. Then, take out the door stamping part that has been stamped and the cut edge material; The cutting mechanism includes an electric telescopic rod. The top end of the electric telescopic rod is fixedly connected to the inside of the installation groove. The number of the electric telescopic rods is multiple. The bottom ends of the multiple electric telescopic rods extend into the inside of the receiving groove and are jointly fixedly connected to a tool holder. A tool bit is arranged at the bottom of the tool holder. A disassembly and assembly mechanism is jointly arranged between the tool holder and the tool bit. When cutting the excess plate after stamping, start the electric telescopic rod to drive the tool holder to move downward. Thus, the tool bit at the bottom side of the tool holder moves downward to cut the excess material, which can ensure that the stamping part is cut for its excess edge material after stamping is completed, preventing the problem of large dimensional errors after cutting when stamping is not completed, and improving the stamping quality of the stamping part. Long-term wear and cutting make the part of the tool bit prone to damage. Thus, the tool bit can be replaced through the disassembly and assembly mechanism. The single tool bit can be replaced without replacing the entire die, saving production costs.

[0007] Preferably, a signal transmitter is fixedly connected to one side of the top of the tool holder. A first signal receiver is fixedly installed inside the receiving groove, and a second signal receiver is fixedly connected inside the receiving groove. The second signal receiver is located on the bottom side of the first signal receiver. The signal transmitter, the first signal receiver, and the second signal receiver are all on the same vertical plane. When the tool head moves downward for cutting, the signal transmitter sends a signal. When the second signal receiver can just receive the signal, at this time, the tool head just moves to the bottom side of the cutting groove, and at this time, the cutting of the excess sheet is completed. Then, the controller controls the electric telescopic rod to stop moving downward, and the electric telescopic rod moves upward again, so that the tool head retracts into the receiving groove until the first signal receiver receives the signal. At this time, the electric telescopic rod drives the tool head to stop moving. Then, the moving die moves upward to open the mold, and the stamped car door is taken out, which can ensure that the cutting is carried out after the stamping is completed.

[0008] Preferably, a displacement sensor is fixedly connected to one side of the top of the fixed die, and the top of the displacement sensor is flush with the upper surface of the fixed die. When stamping the car door of a new energy vehicle, first place the sheet on the surface of the fixed die so that the sheet covers the stamping cavity. Then, the hydraulic rod in the hydraulic cylinder extends downward, and the hydraulic rod drives the moving die under the moving plate to move downward until the displacement sensor monitors that the distance between the fixed die and the moving die is zero, that is, after the moving die contacts the fixed die, the electric telescopic rod starts to drive the tool head to cut the excess sheet.

[0009] Preferably, a cutting groove is formed in the top of the fixed die, and the tool head and the cutting groove are on the same vertical plane, which is convenient for completely cutting off the excess sheet by using the cutting groove.

[0010] Preferably, the disassembly and assembly mechanism includes a plug board, the plug board is fixedly connected to the top of the tool head, and a slot is formed in the bottom of the tool holder, and the plug board is inserted into the slot.

[0011] Preferably, a clamping block is slidably connected inside the tool holder, one side of the clamping block extends into the slot, a clamping groove is formed in one side of the plug board, and one end of the clamping block is clamped inside the clamping groove.

[0012] Preferably, limiting plates are fixedly connected to both sides of the clamping block. A limiting groove is formed inside the tool holder. The limiting plates are slidably connected to the inside of the limiting groove. A pressing spring is elastically connected between the surface of the limiting plate and the inner wall of the limiting groove. When replacing a damaged tool bit, first, start the electric telescopic rod through the controller to drive the tool bit and the tool holder to move downward until both the tool bit and the tool holder are at the bottom of the receiving groove, that is, both the tool holder and the tool bit are exposed. Then, manually pull the pull plate outward to move one end of the clamping block out of the clamping groove, and then take out the insertion plate from the insertion slot, so that the old tool bit can be taken out. When installing a new tool bit, insert the insertion plate into the insertion slot, and then release the pull plate. Under the push of the pressing spring, one side of the clamping block is clamped into the inside of the clamping groove, thus completing the replacement of the tool bit. The arrangement of the limiting groove and the limiting plate can prevent the clamping block from falling out of the tool holder.

[0013] Preferably, a pull plate is fixedly connected to one side of the clamping block. The pull plate is located outside the tool holder. The pull plate can facilitate people to pull or push the clamping block by hand, making the operation more convenient.

[0014] Preferably, a fixing groove is formed at the bottom of the clamping block. A fixing plate is slidably connected to the inside of the fixing groove. A weight block is fixedly connected to the bottom of the fixing plate. After moving one side of the clamping block out of the clamping groove, if the clamping block is directly released, it will return to its original position under the action of the pressing spring, which is not convenient for releasing the hand to pull out other clamping blocks from the clamping groove. Therefore, when pulling out the clamping block, the fixing plate moves downward under the action of the weight block, so that the fixing plate is clamped on one side of the tool holder, and the clamping block can be held stationary, which is convenient for operating other disassembly and assembly mechanisms. And when the clamping block needs to be moved, the fixing block is retracted into the fixing groove, and then the clamping block can be moved. Through the arrangement of the fixing groove, the fixing block and the weight block, it is convenient for people to free their hands to operate other parts of the disassembly and assembly mechanisms, etc., and it is more convenient to use.

[0015] Preferably, heat dissipation holes are formed on the surface of the moving die. One side of the heat dissipation holes communicates with the inside of the receiving groove. The heat dissipation holes can dissipate the heat inside the die, preventing the temperature inside the die from being too high and deforming, thus reducing the stamping quality.

[0016] (III) Beneficial Effects The present invention provides a stamping die for a new energy vehicle door. It has the following beneficial effects: (1). For this stamping die of the new energy vehicle door, through the settings of the cutting mechanism, the receiving groove and the mounting groove, it is possible to cut the excess material at the edge of the stamped part after stamping is completed, rather than cutting while stamping. This avoids insufficient stamping material caused by cutting the sheet just after stamping, thereby preventing the overall shrinkage of the stamped part after stamping. By using the cutting mechanism to perform cutting after the stamping of the stamped part is completed, the dimensional error during the stamping process is reduced, and the quality of the stamped part is improved.

[0017] (2). For this stamping die of the new energy vehicle door, through the setting of the disassembly and assembly mechanism, the tool head part can be replaced individually without replacing the entire die, which reduces the production cost. Moreover, the replacement is convenient and fast, without the need to disassemble and assemble multiple bolts, improving the replacement rate and indirectly increasing the production rate.

[0018] (3). For this stamping die of the new energy vehicle door, through the settings of the receiving groove and the mounting groove, etc., when the staff takes the stamped part, the tool head retracts into the interior of the receiving groove, so that the tool head is not likely to scratch the staff, improving the safety of the die during use. And when using the cutting mechanism for cutting, it is also carried out inside the die, and after cutting is completed, the tool head retracts into the receiving groove, improving the safety during the cutting process.

[0019] (4). For this stamping die of the new energy vehicle door, through the settings of the fixing groove, the fixing plate and the counterweight block, when disassembling and assembling the tool head, the clamping block will not move automatically under the action of the abutting spring, liberating the hands of the staff and facilitating the operation of the staff.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Refer to Figures 1-9 , the present invention provides a technical solution: a stamping die for a new energy vehicle door, the structure of which includes a bracket 1. The inner corners of the bracket 1 are fixedly connected with guide rods 2. A moving plate 3 is slidably connected to the surfaces of the four guide rods 2. The bottom of the moving plate 3 is fixedly connected with a moving die 4. The inner bottom of the bracket 1 is fixedly connected with a fixed die 5. An accommodating groove 6 is opened at the bottom of the moving die 4. An installation groove 7 is opened inside the moving die 4. The bottom of the installation groove 7 communicates with the top of the accommodating groove 6. A cutting mechanism 8 is provided between the accommodating groove 6 and the inside of the installation groove 7. The bottom side of the front surface of the bracket 1 is fixedly connected with a controller 9. A hydraulic cylinder 10 is fixedly connected to the top of the bracket 1. A hydraulic rod 11 extends from the bottom end of the hydraulic cylinder 10. The bottom end of the hydraulic rod 11 passes through the top wall of the bracket 1 and is fixedly connected to the top of the moving plate 3. Place the plate on the surface of the fixed die 5 so that the plate covers the stamping cavity. Then, the hydraulic rod 11 in the hydraulic cylinder 10 extends downward. The hydraulic rod 11 drives the moving die 4 under the moving plate 3 to move downward until the displacement sensor 88 monitors that the distance between the fixed die 5 and the moving die 4 is zero, that is, after the moving die 4 contacts the fixed die 5, the redundant plate is cut by the cutting mechanism 8. After cutting, the hydraulic rod 11 drives the moving die 4 to move upward to return to the original position, and then the stamped and cut door stamping part is taken out; The cutting mechanism 8 includes an electric telescopic rod 81. The top bottom of the electric telescopic rod 81 is connected to the inside of the installation groove 7. The number of the electric telescopic rods 81 is set to be multiple. The bottom ends of the multiple electric telescopic rods 81 extend into the inside of the accommodation groove 6 and are commonly fixedly connected to a tool holder 82. A cutter head 83 is arranged at the bottom of the tool holder 82. A disassembly and assembly mechanism 84 is commonly arranged between the tool holder 82 and the cutter head 83. When cutting the redundant sheet metal after stamping, the electric telescopic rod 81 is started to drive the tool holder 82 to move downward. Thus, the cutter head 83 at the bottom side of the tool holder 82 moves downward to cut the redundant material. After long-term wear and cutting, part of the cutter head 83 is prone to be damaged. Thus, the cutter head 83 is replaced and used through the disassembly and assembly mechanism 84.

[0024] Among them, a signal transmitter 85 is fixedly connected to one side of the top of the tool holder 82. A first signal receiver 86 is fixedly installed inside the accommodation groove 6. A second signal receiver 87 is fixedly connected to the inside of the accommodation groove 6. The second signal receiver 87 is located at the bottom side of the first signal receiver 86. The signal transmitter 85, the first signal receiver 86, and the second signal receiver 87 are all located on the same vertical plane. When the cutter head 83 moves downward for cutting, a signal is sent through the signal transmitter 85. When the second signal receiver 87 can just receive the signal, at this time, the cutter head 83 just moves to the bottommost side of the cutting groove 89. At this time, the cutting of the redundant sheet metal is completed. Thus, the controller 9 controls the electric telescopic rod 81 to stop moving downward, and the electric telescopic rod 81 moves upward again, so that the cutter head 83 retracts into the inside of the accommodation groove 6 until the first signal receiver 86 receives the signal. At this time, the electric telescopic rod 81 drives the cutter head 83 to stop moving. Then, the moving die 4 moves upward to open the mold, and the stamped car door is taken out.

[0025] Among them, a displacement sensor 88 is fixedly connected to one side of the top of the fixed die 5. The top of the displacement sensor 88 is flush with the upper surface of the fixed die 5. When stamping the new energy vehicle door, first place the sheet metal on the surface of the fixed die 5 so that the sheet metal covers the stamping cavity. Then, the hydraulic rod 11 in the hydraulic cylinder 10 extends downward. The hydraulic rod 11 drives the moving die 4 under the moving plate 3 to move downward until the displacement sensor 88 monitors that the distance between the fixed die 5 and the moving die 4 is zero, that is, after the moving die 4 contacts the fixed die 5, the electric telescopic rod 81 starts to drive the cutter head 83 to cut the redundant sheet metal.

[0026] Among them, a cutting groove 89 is formed in the top of the fixed die 5. The cutter head 83 and the cutting groove 89 are located on the same vertical plane. The cutting groove 89 is used to conveniently cut off the redundant sheet metal completely.

[0027] Among them, the disassembly and assembly mechanism 84 includes an insertion plate 841. The insertion plate 841 is fixedly connected to the top of the cutter head 83. A slot 842 is formed in the bottom of the tool holder 82. The insertion plate 841 is inserted into the inside of the slot 842.

[0028] Among them, the inside of the knife seat 82 is slidably connected with a card block 843, one side of the card block 843 extends to the inside of the slot 842, and one side of the inserting plate 841 is provided with a card slot 844, and one end of the card block 843 is connected to the inside of the card slot 844.

[0029] The two sides of the clamping block 843 are fixedly connected to the limiting plates 845, and the interior of the knife holder 82 is provided with a limiting groove 846, and the limiting plate 845 is slidably connected to the interior of the limiting groove 846. The surface of the limiting plate 845 and the inner wall of the limiting groove 846 are elastically connected with a tightening spring 847. When replacing a damaged cutter head 83, the controller 9 is first used to start the electric telescopic rod 81 to drive the cutter head 83 and the knife holder 82 to move downward until the cutter head 83 and the knife holder 82 are both located at the bottom of the accommodating groove 6, that is, the knife holder 82 and the cutter head 83 are exposed to the outside, and then the cutter head 83 is manually The pull plate 848 is pulled outward, so that the pull plate 848 drives one end of the block 843 to move out of the slot 844, and then the insert plate 841 is removed from the slot 842, so that the old cutter head 83 can be taken out. When installing a new cutter head 83, the insert plate 841 is inserted into the slot 842, and then the pull plate 848 is released. Under the push of the tightening spring 847, one side of the block 843 is stuck into the inside of the slot 844, thereby completing the replacement of the cutter head 83. The setting of the limit slot 846 and the limit plate 845 can prevent the block 843 from falling out of the cutter seat 82.

[0030] Among them, a pull plate 848 is fixedly connected to one side of the clamping block 843, and the pull plate 848 is located on the outside of the knife seat 82. The pull plate 848 can facilitate people to pull out or push the clamping block 843 by hand, making the operation more convenient.

[0031] Among them, a fixing groove 849 is provided at the bottom of the block 843, and a fixing plate 8410 is slidably connected to the inside of the fixing groove 849, and a counterweight block 8411 is fixedly connected to the bottom of the fixing plate 8410. After one side of the block 843 is moved out of the slot 844, if you let go of the block 843 directly, the block will return to its original position under the action of the tightening spring 847, making it inconvenient to let go of the hand and pull out other blocks 843 from the slot 844. Then, when the block 843 is pulled out, the counterweight block 8411 causes the fixing plate 8410 to move downward, so that the fixing plate 8410 is stuck on one side of the knife seat 82, which can lock the block 843 and prevent it from moving, thereby facilitating the operation of other disassembly and assembly mechanisms 84, and when the block 843 needs to be moved, the fixing block is retracted into the inside of the fixing groove 849 and the block 843 can be moved.

[0032] Among them, heat dissipation holes 12 are formed on the surface of the moving die 4. One side of the heat dissipation holes 12 communicates with the inside of the receiving groove 6. The heat dissipation holes 12 can dissipate the heat inside the die, preventing the temperature inside the die from being too high and deforming, which reduces the stamping quality.

[0033] Working principle: When stamping the door of a new energy vehicle, first place the sheet on the surface of the fixed die 5 so that the sheet covers the stamping cavity. Then, the hydraulic rod 11 in the hydraulic cylinder 10 extends downward. The hydraulic rod 11 drives the moving die 4 under the moving plate 3 to move downward until the displacement sensor 88 monitors that the distance between the fixed die 5 and the moving die 4 is zero, that is, after the moving die 4 contacts the fixed die 5, the electric telescopic rod 81 starts to drive the cutter head 83 to cut the excess sheet. When cutting the excess sheet after stamping, start the electric telescopic rod 81 to drive the tool holder 82 to move downward. Thus, the cutter head 83 at the bottom of the tool holder 82 moves downward and cuts off the excess material. When the cutter head 83 moves downward and cuts, a signal is sent through the signal transmitter 85. When the second signal receiver �7 just receives the signal, at this time, the cutter head 83 just moves to the bottom of the cutting groove 89, and at this time, the cutting of the excess sheet is completed. Thus, the controller 9 controls the electric telescopic rod 81 to stop moving downward, and the electric telescopic rod 81 moves upward again, so that the cutter head 83 retracts into the inside of the receiving groove 6 until the first signal receiver 86 receives the signal. At this time, the electric telescopic rod 81 drives the cutter head 83 to stop moving. Then, the moving die 4 moves upward to open the die, and the stamped door is taken out. When replacing the damaged cutter head 83 through the disassembly and assembly mechanism 84, first start the electric telescopic rod 81 through the controller 9 to drive the cutter head 83 and the tool holder 82 to move downward until the cutter head 83 and the tool holder 82 are both at the bottom of the receiving groove 6, that is, the tool holder 82 and the cutter head 83 are both exposed. Then, manually pull the pull plate 848 outward, so that one end of the clamping block 843 is removed from the clamping groove 844. After that, take out the insertion plate 841 from the insertion slot 842, and then the old cutter head 83 can be taken out. When installing a new cutter head 83, insert the insertion plate 841 into the insertion slot 842, and then release the pull plate 848. Under the push of the pressing spring 847, one side of the clamping block 843 is clamped into the inside of the clamping groove 844, thus completing the replacement of the cutter head 83. The setting of the limiting groove 846 and the limiting plate 845 can prevent the clamping block 843 from falling off the tool holder 82.
