[0026] 2. In the present invention, a driving hydraulic lifting device is installed on the top of the upper die seat through the designed feeding assembly and linkage assembly, and the driving hydraulic lifting device is controlled to drive the upper die seat to move upward. During the upward movement of the upper die seat, the driving teeth associated with the positioning seat are also driven to perform synchronous actions. By utilizing the linkage effect between the driving teeth and the driving gear, the linear force on the upper die seat can be converted into a torque and act on the corresponding first transfer shaft, and the first transfer shaft drives the feeding roller to perform a stable rotation in the first bearing. At the same time, the first transfer shaft also utilizes the linkage effect between the two linkage gears to convert the torque into It is used on another feed roller, and utilizes the meshing relationship between the two linked gears to drive the two feed rollers to rotate, and the rotation directions are opposite to each other, so that the rotation action of the two feed rollers can be utilized to drive the metal belt to feed in the corresponding feed trough, and utilizes the force applied to the upper die base by the driven hydraulic lifting equipment to drive the metal belt to automatically move toward the upper die base and the built-in die cavity of the upper die base, and combines the upper die base and the conveying mechanism of the metal belt, so that the feeding and stamping working frequencies are exactly the same, which effectively ensures the synchronous stability of the feeding, and the conveying structure of the metal belt is simple, easy to maintain, and has a good use effect.

The invention has a wide range of applications and high flexibility.

[0029] 5. In the present invention, by means of the designed smoothing component, when the control-driven hydraulic lifting device drives the upper die seat downward, the pressure wheel will contact the metal belt before the smoothing roller, and the elastic telescopic characteristics of the first elastic telescopic rod can be used to realize the pressing behavior of the pressure wheel, and then the smoothing roller contacts the metal belt. When the smoothing roller encounters resistance, it will rotate through the pin shaft, and then it can drive the smoothing roller to roll on the surface of the metal belt, thereby realizing the smoothing of the metal belt.

[0046] Specifically, the first transfer shaft 402 drives the feed roller 401 to perform a stable rotation in the first bearing 404. At the same time, the first transfer shaft 402 also utilizes the linkage effect between the two linkage gears 403 to apply torque to the other feed roller 401. By utilizing the meshing relationship between the two linkage gears 403, the two feed rollers 401 can be driven to rotate, and the rotation directions are opposite to each other, so that the rotation action of the two feed rollers 401 can be utilized to drive the metal belt to feed in the corresponding feed trough 3.

[0047] The present embodiment is specifically as follows: controlling the driven hydraulic lifting device to drive the upper mold base 1 downward. Since the edge of the bottom of the driving tooth 602 can rotate in the third bearing 605 through the second adapter shaft 604, when it encounters resistance from the driving gear 408, it will rotate by itself, thereby preventing the downward driving force applied by the driven hydraulic lifting device from acting on the feeding roller 401.

[0049] The specific embodiment of the present invention is as follows: a driven hydraulic lifting device is installed on the top of the upper mold base 1, and the driven hydraulic lifting device is controlled to drive the upper mold base 1 upward. During the upward movement of the upper mold base 1, the driving teeth 602 associated with the positioning seat 607 are also driven to perform synchronous movements. By utilizing the linkage effect between the driving teeth 602 and the driving gear 408, the linear force on the upper mold base 1 can be converted into torque and act on the corresponding first transfer shaft 402.

[0051] The specific implementation of this embodiment is as follows: turning the first knob 504 drives the first threaded rod 502 to rotate in the second bearing 503. Under the combined effect of torque and thread engagement force, the two sliding support seats 405 will drive the feed roller 401 to displace on the surface of the first threaded rod 502. The movement directions are opposite to each other, thereby being able to synchronously achieve synchronous regulation of the two feed rollers 401. Moreover, since the modulus of the two linkage gears 403 is relatively large, fine-tuning of the two feed rollers 401 can be achieved according to the thickness of the metal strip.

[0053] The specific embodiment of this invention is as follows: turning the second knob 612 drives the second threaded rod 609 to rotate in the threaded connection groove 610. Under the combined effect of torque and thread engagement force, the initial height of the driving tooth 602 can be controlled, thereby regulating the rotation angle of the driving gear 408 driven by the driving tooth 602 when moving upward, thereby realizing the feeding amount of a single metal strip, and having a wide range of applications.

[0054] Specifically, Figure 7 As shown, a second through-connecting hole 608 is provided at the top of the positioning seat 607, a second threaded rod 609 is sleeved inside the second through-connecting hole 608, an outer threaded surface of the second threaded rod 609 is threadedly connected to an inner threaded surface of a threaded connection groove 610 provided at the top of the linkage seat 601, and a fourth bearing 611 is sleeved on the surface of the second threaded rod 609.

[0055] The present embodiment specifically utilizes the force exerted on the upper die base 1 by the driven hydraulic lifting equipment to drive the metal belt to automatically move toward the upper die base 1 and the inner die cavity of the upper die base 1, and combines the upper die base 1 and the conveying mechanism of the metal belt, so that the feeding and stamping working frequencies are exactly the same, and the synchronous stability of the feeding is effectively guaranteed.

The top of the pressure wheel 701 is fixedly connected to the bottom of the upper mold base 1 through a first elastic telescopic rod 702. A smoothing roller 703 is provided on the side of the pressure wheel 701 close to the feed roller 401, and the smoothing roller 703 is fixedly connected to the inner wall of the feed trough 3.

The surface of the pin shaft 706 is also sleeved with a spring, and one end of the spring is fixedly connected to the surface of the pin shaft 706, and the other end of the spring is fixedly connected to the inner wall of the adapter seat 705.

[0061] The specific embodiment of this invention is as follows: when the control-driven hydraulic lifting equipment drives the upper mold base 1 downward, the pressure wheel 701 will contact the metal belt before the smoothing roller 703, and the elastic telescopic characteristics of the first elastic telescopic rod 702 are utilized to realize the pressing behavior of the pressure wheel 701, and then the smoothing roller 703 contacts the metal belt. When the smoothing roller 703 encounters resistance, it will rotate through the pin shaft 706, and then the smoothing roller 703 can be driven to roll on the surface of the metal belt, thereby realizing the smoothing of the metal belt.

[0062] Working principle: When in use, a driven hydraulic lifting device is installed on the top of the upper mold base 1, and the driven hydraulic lifting device is controlled to drive the upper mold base 1 upward. During the upward movement of the upper mold base 1, the driving teeth 602 associated with the positioning seat 607 are also driven to perform synchronous actions. By utilizing the linkage effect between the driving teeth 602 and the driving gear 408, the linear force on the upper mold base 1 can be converted into a torque and act on the corresponding first transfer shaft 402. The first transfer shaft 402 drives the feed roller 401 to perform a stable rotation movement in the first bearing 404. At the same time, the first transfer shaft 402 also utilizes the linkage effect between the two linkage gears 403 to apply torque to the other feed roller 401. The meshing relationship between the linkage gears 403 can drive the two feed rollers 401 to rotate, and the rotation directions are opposite to each other, so that the rotation action of the two feed rollers 401 can be used to drive the metal belt to feed in the corresponding feed trough 3, and the force applied to the upper die base 1 by the driving hydraulic lifting device is used to drive the metal belt to automatically move toward the upper die base 1 and the internal mold cavity of the upper die base 1, and the upper die base 1 and the conveying mechanism of the upper die base 1 and the metal belt are combined, so that the feeding and stamping working frequencies are exactly the same, which effectively ensures the synchronous stability of the feeding. The conveying structure of the metal belt is simple, easy to maintain, and has a good use effect. The driving hydraulic lifting device is controlled to drive the upper die base 1 downward. Since the edge of the bottom of the driving tooth 602 can pass The second transfer shaft 604 rotates in the third bearing 605, so when it encounters resistance from the driving gear 408, it will rotate automatically, thereby being able to prevent the downward driving force applied by the driving hydraulic lifting equipment from acting on the feeding roller 401, so that the rotation direction of the feeding roller 401 is oriented, ensuring the stability of the metal strip during the conveying process, and the second transfer shaft 604 is also subjected to the elastic supporting force generated by the torsion spring 606, so when the driving tooth 602 disengages from the driving gear 408, it will reset, effectively ensuring the stability of the subsequent power transmission relationship, and turning the first knob 504 drives the first threaded rod 502 to rotate in the second bearing 503. Under the effect of using, the two sliding support seats 405 will drive the feeding roller 401 to displace on the surface of the first threaded rod 502, and the moving directions are opposite to each other, so that the synchronous regulation of the two feeding rollers 401 can be realized synchronously, and because the modulus of the two linkage gears 403 is large, the fine-tuning action between the two feeding rollers 401 can be realized according to the thickness of the metal strip, and the second knob 612 is turned to drive the second threaded rod 609 to rotate in the threaded connection groove 610. Under the combined effect of torque and thread bite force, the initial height of the driving teeth 602 can be controlled, and then the rotation angle of the driving gear 408 driven by the driving teeth 602 when moving upward is regulated, that is, the feeding amount of a single metal strip is realized, which has a wide range of applications.It is also highly flexible. When the control-driven hydraulic lifting device drives the upper die seat 1 downward, the pressure wheel 701 will contact the metal belt before the smoothing roller 703. The elasticity of the first elastic telescopic rod 702 can be used to achieve the pressing behavior of the pressure wheel 701, and then the smoothing roller 703 contacts the metal belt. When the smoothing roller 703 encounters resistance, it will rotate through the pin 706, and then it can drive the smoothing roller 703 to roll on the surface of the metal belt, thereby achieving the smoothing of the metal belt.
