Description

Technical Field

[0002] Spring leaves have various shapes and structures due to different uses. According to the appearance, they can be divided into two categories: straight leaf springs and curved leaf springs. According to the shape of the plate, they can be divided into rectangular, trapezoidal, triangular, step-shaped, special-shaped, etc. During production, spring leaves are generally first formed by cold rolling, and then heat treated to eliminate internal stress. This can greatly increase the service life of the spring leaves. The production of spring leaves requires hardware spring leaf production and processing equipment.

[0003] When processing the spring sheet, the existing hardware spring sheet production and processing device can complete the two processes of bending and punching at one time on the same mold. However, when the spring sheet is bent, the bending of the spring sheet will shorten the overall length, so that when punching, the bent spring sheet will shift or pop out inside the mold, causing the punching position to shift, thereby increasing the defective rate of the spring sheet.

[0023] The transmission mechanism includes two second transmission rods 406 hinged on the top of the lifting plate 402 and two fixed blocks 404 hinged on the bottom of the fixed block 404. Two second transmission rods 406 are provided with two rotating shafts at one end away from the lifting plate 402 and two first transmission rods 405 are provided with two rotating shafts. Two rotatable third transmission rods 407 are provided on the two rotating shafts. A power block 408 is hinged at one end of the two third transmission rods 407 away from the two rotating shafts. A first spring 403 is provided between the power block 408 and the lifting plate 402. The third transmission rod 407 is provided with a first spring 403. 07, two grooves are symmetrically arranged, the first transmission rod 405 and the second transmission rod 406 are rotatably installed in one of the grooves through a rotating shaft, two connecting shafts are symmetrically arranged at both ends of the power block 408, and the power block 408 is installed in the other groove through the connecting shaft.

[0024] Two limit blocks 410 are arranged between the lifting plate 402 and the two first transmission rods 405. The two limit blocks 410 are fixed on the outer walls of the two fixed rods 401, and the ends of the two limit blocks 410 away from the fixed rods 401 are provided with arc-shaped chamfers.

[0025] By adopting the above technical solution: When in use, after the raw material of the spring sheet to be processed is placed on the lower mold, when the upper fixed plate moves downward, the upper fixed plate contacts the raised portion, so that the raised portion drives the power block 408 to move downward, and the power block 408 drives the third transmission rod 407 to move downward, so that the third transmission rod 407 rotates around the power block 408, and at the same time the third transmission rod 407 pushes the rotating shaft to move, so that the rotating shaft drives the first transmission rod 405 and the second transmission rod 406 to move, and the first transmission rod 405 is limited by the fixed block 404, so that the second transmission rod 406 drives the lifting plate 402 to move downward, and the lifting plate 402 drives the main pressing plate 409 to move, so that the bottom of the main pressing plate 409 contacts the top of the auxiliary pressing plate 502, and the raw material of the spring sheet is pressed tightly. , a laborious lever is formed by the first transmission rod 405, the second transmission rod 406 and the third transmission rod 407, and the stroke of the lifting plate 402 is controlled by using the dead point formed by the first transmission rod 405, the second transmission rod 406 and the third transmission rod 407, so as to avoid the raw material of the spring sheet being damaged by excessive pressure of the power block 408. When the mold bends the raw material of the spring sheet, the raw material of the spring sheet bends and contracts, so that the raw material of the spring sheet drives the main pressure plate 409 and the auxiliary pressure plate 502 to move, so that the distance between the main pressure plate 409 and the auxiliary pressure plate 502 and the lower fixed plate 3 becomes smaller. While the spring sheet is clamped and limited by the main pressure plate 409 and the auxiliary pressure plate 502, it can also prevent the raw material of the spring sheet from being offset on the mold when it is bent.

[0026] Secondly, refer to Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the lifting mechanism includes two inclined rods 510 hinged on the lifting plate 503, a positioning shaft is arranged between the two inclined rods 510, a propulsion block 511 is fixed on the positioning shaft, a second spring 505 is fixed to the bottom of the propulsion block 511, the two inclined rods 510 are cross-arranged below the lifting plate 503, the free end of the second spring 505 is fixed to the lower fixed plate 3, and the propulsion block 511 is arranged between the two inclined rods 510.

[0027] Two main mounting blocks are fixed at the bottom of the lifting plate 503, and two inclined rods 510 are hinged on the two main mounting blocks. Two auxiliary mounting blocks are arranged at one end of the two inclined rods 510 away from the two main mounting blocks, and the lower fixed plate 3 is provided with sliding grooves adapted to the two auxiliary mounting blocks.

[0028] By adopting the above technical solution: When in use, when the spring sheet drives the secondary pressure plate 502 to move, the secondary pressure plate 502 drives the insertion rod 507 to move, so that the insertion rod 507 moves along the inside of the slot, so that the insertion rod 507 passes through the slot. At the same time, the secondary pressure plate 502 drives the secondary wedge block to move, so that the secondary wedge block moves to the outside of the secondary wedge slot, so that the secondary pressure plate 502 is separated from the base 501, and the second spring 505 releases its elastic force to push the propulsion block 511 to move upward, so that the propulsion block 511 drives the positioning shaft to move upward, so that the positioning shaft drives the inclined rod 510 to move, and the inclined rod 510 drives the lifting plate 503 to move upward, so that the lifting plate 503 drives the secondary pressure plate 502 to move upward through the insertion rod 507, and the secondary pressure plate 502 and the main pressure plate 409 drive the processed spring sheet to move upward, so that the processed spring sheet is separated from the mold, thereby facilitating people to demold the spring sheet and improving the production efficiency of the device.

[0029] Again, reference Figure 8 and Fig. 9 As shown, two clamping plates 504 are symmetrically fixed on the top of the lower fixed plate 3, two L-shaped movable grooves are arranged on the two clamping plates 504, an extension rod 506 is fixed to the outer wall of the insertion rod 507, and two rotating adjustment knobs are symmetrically arranged at both ends of the extension rod 506, and the adjustment knobs are inserted in the movable grooves.

[0030] By adopting the above technical solution: When in use, push the adjusting button downward to move the adjusting button along the moving groove. The adjusting button drives the insertion rod 507 to move downward through the extension rod 506. The insertion rod 507 drives the lifting plate 503 to move downward. The lifting plate 503 drives the auxiliary pressure plate 502 to move downward through the insertion rod 507, so that the auxiliary pressure plate 502 is separated from the main pressure plate 409, thereby taking out the processed spring sheet, further improving the convenience of the device.

[0031] Finally, reference Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, two retractable locking rods 508 are provided at both ends of the lower mold, and positioning grooves matched with the locking rods 508 are provided on the lower mold, and a third spring 509 is provided between the locking rods 508 and the lower fixing plate 3.

[0032] A baffle is provided at one end of the locking rod 508, and a first curved surface is provided on the baffle. A second curved surface is provided at the end of the insertion rod 507 away from the auxiliary pressure plate 502. The first curved surface cooperates with the second curved surface so that the second curved surface can move along the first curved surface, so that the insertion rod 507 can push the locking rod 508 to move.

[0033] By adopting the above technical solution: When in use, when the insertion rod 507 moves downward, the insertion rod 507 pushes the locking rod 508 to move inside the positioning groove of the lower fixed plate 3, compressing the third spring 509. When the adjusting button moves to the inflection point of the moving groove, the third spring 509 releases its elastic force, causing the third spring 509 to push the insertion rod 507 to move through the locking rod 508, so that the insertion rod 507 drives the adjusting button to move along the moving groove through the extension rod 506. At the same time, the insertion rod 507 drives the auxiliary pressure plate 502 to move, so that the auxiliary pressure plate 502 drives the auxiliary wedge block to move into the auxiliary wedge groove, and the auxiliary pressure plate 502 is limited by the cooperation of the auxiliary wedge groove and the auxiliary wedge block, so that the auxiliary pressure plate 502 limits the lifting plate 503 through the insertion rod 507, so that the auxiliary pressure plate 502 and the lifting plate 503 are reset, which is convenient for the subsequent processing of the raw materials of the spring sheet.
