Description

Technical Field

[0001] The invention belongs to the technical field of sheet metal stamping dies, and in particular is a sheet metal stamping die for new energy vehicles. Background Art

[0002] Automotive sheet metal is a common component of automobiles. When it is produced in large quantities, it needs to be quickly stamped using a forming die. A pressure processing method is used to apply pressure to the material at room temperature using a die installed on a press to cause separation or plastic deformation, thereby obtaining the required parts.

[0003] The existing continuous stamping process of automobile sheets is roughly as follows: first, the staff places the sheet to be stamped on the top of the punch die, and then the punch in the punch moves down to press the sheet into the corresponding die to complete the processing, and then the punch of the punch moves up and returns to take the formed product out of the die, and then the subsequent sheet to be stamped is placed on the die again, and the punch moves down again... This reciprocating cycle is used to achieve continuous stamping of automobile sheets. The continuous stamping of the above sheets requires the staff to repeatedly place the sheets on the die, and each placement of the sheets can only be carried out after the previous stamping is completed and the punch moves up. Therefore, the time available for placing the sheets is relatively rushed each time, and the position between the sheet and the die is prone to offset when the sheets are placed hastily, resulting in a high defective rate of the products after stamping. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a sheet metal stamping die for a new energy vehicle.

The transfer assembly 20 is slidably arranged on the stamping The first driving component 30 is arranged on the side of the transfer component 20 on the upper part of the punch table 10. When the second driving component 50 drives the punch 40 to move downward and approach the punching groove 101, the first driving component 30 drives the transfer component 20 to slide along the upper part of the punch table 10 to transfer the sheet to be punched to above the punching groove 101. When the punch 40 presses the sheet to be punched into the inside of the punching groove 101, the first driving component 30 drives the transfer component 20 to slide in the opposite direction along the upper part of the punch table 10.

[0029] When stamping automobile sheets, the sheet to be stamped can be placed on the transfer assembly 20, and then the second drive assembly 50 drives the punch 40 to move downward, so that the punch 40 gradually approaches the stamping groove 101. At this time, the first drive assembly 30 drives the transfer assembly 20 to slide along the upper part of the stamping table 10 to transfer the sheet to be stamped to the upper part of the stamping groove 101. Then the downward-moving punch 40 acts on the sheet and presses the sheet into the inside of the stamping groove 101 to realize the stamping forming of the sheet. At the same time, the first drive assembly 30 drives the transfer assembly 20 to slide in the opposite direction along the upper part of the stamping table 10, so that the transfer assembly 20 is removed from the position of the stamping groove 101, so that the staff can promptly place the subsequent sheet to be stamped back on the transfer assembly 20, thereby improving the stamping efficiency of the sheet.

[0030] See also Figure 1 as well as Figure 2In one embodiment, the transfer assembly 20 includes a carrier frame 202 and a limit bar 203 fixedly arranged on the inner wall of the carrier frame 202, the first driving assembly 30 includes a support rod 301, a first rack 302, a gear 303 and a second rack 305, the side wall of the gear 303 is rotatably provided with a support plate 304, the support plate 304 is fixedly installed on the upper part of the stamping table 10, one end of the support rod 301 is fixedly connected to the side wall of the punch 40, and the other end extends to one side of the gear 303, the first rack 302 is fixedly arranged on the side wall of the support rod 301 and can mesh with the gear 303, one end of the second rack 305 is fixedly connected to the side wall of the carrier frame 202, and the other end extends to one side of the gear 303 and meshes with the gear 303.

[0031] By placing the plate to be punched on the inner side of the plate carrier frame 202, and using the limit bar 203 to provide support for the plate from the bottom edge of the plate, when the second driving assembly 50 drives the punch 40 to move downward, the punch 40 drives the support rod 301 and the first rack 302 to move downward, and the meshing action of the first rack 302 and the gear 303 drives the gear 303 to rotate, and then the meshing action of the gear 303 and the second rack 305 drives the plate carrier frame 202 to slide along the upper part of the stamping table 10, and when the plate carrier frame 202 slides, it drives the plate to move toward the stamping groove 101. When the plate carrier frame 202 drives the plate to move to the upper part of the stamping groove 101, the punch 40 just acts on the plate, and then presses the plate into the inside of the stamping groove 101, thereby realizing the stamping forming of the plate.

[0032] See also Figure 1 In one embodiment, a baffle 103 is fixedly provided on the upper portion of the stamping table 10, and one side of the carrier frame 202 is connected to the baffle 103 through a first elastic member 201. The first elastic member 201 is used to provide elastic tension to the carrier frame 202, and a notch is opened on one side of the carrier frame 202 facing the stamping groove 101.

[0033] When the punch 40 moves downward and drives the plate carrier frame 202 to slide along the upper part of the stamping table 10 through the transmission action of the first rack 302, the gear 303 and the second rack 305, the first elastic member 201 is stretched by force. When the punch 40 presses the plate into the inside of the stamping groove 101, the first rack 302 and the gear 303 are disengaged, and the first elastic member 201 pulls the plate carrier frame 202 to make the plate carrier frame 202 slide in the opposite direction along the upper part of the stamping table 10. At this time, the punch 404 moves out from the notch on one side of the plate carrier frame 202, and the plate carrier frame 202 slides away from the upper part of the stamping groove 101, thereby realizing the resetting of the plate carrier frame 202. The staff can place the subsequent plate to be stamped on the inner side of the plate carrier frame 202 again.

[0034] See also Figure 1In one embodiment, a slide rail 102 is fixedly provided on the upper portion of the punching table 10 at the edge of the punching groove 101 , and a slide groove (not shown in the figure) that slidably cooperates with the slide rail 102 is provided at the bottom of the carrier frame 202 .

[0035] The bottom of the plate carrier frame 202 is slidably matched with the slide rail 102 through the slide groove, so that the plate carrier frame 202 can slide smoothly along the upper part of the punching table 10, thereby realizing the smooth transfer of the plate.

[0036] See also Figure 1 and Figure 4 In one embodiment, a socket 105 is provided at the bottom of the stamping slot 101, and a push rod 60 is movably inserted inside the socket 105. A third elastic member (not shown in the figure) is also provided inside the socket 105, and the third elastic member is used to provide elastic support for the push rod 60.

[0037] Initially, the upper part of the push rod 60 is extended into the inside of the stamping groove 101 under the support of the third elastic member. When the punch 40 moves downward and acts on the plate to press the plate into the inside of the stamping groove 101, the push rod 60 is pressurized and moves toward the inside of the socket 105, and the third elastic member is compressed. After the current plate is stamped, the second drive assembly 50 drives the punch 40 to move upward, and the punch 40 moves out of the stamping groove 101. At the same time, the third elastic member pushes the push rod 60, causing the push rod 60 to move upward, and the push rod 60 pushes out the product formed in the inside of the stamping groove 101.

[0038] See also Figure 4 In one embodiment, a push rod 204 is hingedly provided in the notch on one side of the carrier frame 202, and one side of the push rod 204 is connected to the inner wall of the carrier frame 202 through a second elastic member 205, and the second elastic member 205 is used to provide elastic pulling force to the push rod 204.

[0039] After a group of plates are stamped, as the punch 40 moves upward, the push rod 60 pushes the product formed in the stamping groove 101 out of the stamping groove 101, and then the second driving assembly 50 drives the punch 40 to move downward again, and drives the plate carrier frame 202 to slide toward the stamping groove 101 again through the transmission action of the first rack 302, the gear 303 and the second rack 305. During the sliding process of the plate carrier frame 202, the push rod 204 acts on the product pushed out from the stamping groove 101 in advance, and then pushes the product laterally away from the upper position of the stamping groove 101, and then the plate carrier frame 202 transfers the subsequent plate inside it to the upper part of the stamping groove 101, and the punch 40 presses the subsequent plate into the stamping groove 101, and then The subsequent plate is stamped and formed; when the punch 40 presses the subsequent plate into the inside of the stamping groove 101, the first rack 302 is disengaged from the gear 303, and the first elastic member 201 pulls the carrier frame 202 to slide in the opposite direction along the upper part of the stamping table 10, and the punch 40 moves out of the notch to the outside of the carrier frame 202. At the same time, the punch 40 pushes the push rod 204, so that the push rod 204 rotates outward compared to the carrier frame 202, and the second elastic member 205 is stretched by force until the carrier frame 202 slides in the opposite direction to the initial position, and the push rod 204 passes over the side of the punch 40, and the second elastic member 205 pulls the push rod 204 to rotate in the opposite direction, and the push rod 20 rotates inward compared to the carrier frame 202, and then re-enters the inside of the notch, thereby completing the reset.

[0041] In one embodiment, the second driving component 50 can be a hydraulic cylinder or a linear motor, which is not limited here.

[0042] In the embodiment of the present invention, when stamping an automobile sheet, the sheet to be stamped can be placed on the transfer assembly 20, and then the second drive assembly 50 drives the punch 40 to move downward, so that the punch 40 gradually approaches the stamping groove 101. At this time, the first drive assembly 30 drives the transfer assembly 20 to slide along the upper part of the stamping table 10 to transfer the sheet to be stamped to the upper part of the stamping groove 101. Then the downwardly moved punch 40 acts on the sheet and presses the sheet into the inside of the stamping groove 101 to achieve stamping forming of the sheet. At the same time, the first drive assembly 30 drives the transfer assembly 20 to slide in the opposite direction along the upper part of the stamping table 10, so that the transfer assembly 20 moves from The position of the stamping groove 101 is removed so that the staff can promptly place the subsequent sheet to be stamped back on the transfer assembly 20, thereby improving the stamping efficiency of the sheet. Compared with the prior art, when stamping the automobile sheet, the transfer assembly 20 can automatically and accurately transfer the automobile sheet to the upper position of the stamping groove 101, thereby realizing automatic feeding of the sheet, and after the transfer and feeding of the current sheet is completed, the transfer assembly 20 can be promptly returned from the upper position of the stamping groove 101, thereby reserving sufficient time for the placement of the subsequent sheet, thereby improving the continuous stamping efficiency of the automobile sheet and reducing the defective rate of the formed product.
