Description

Technical Field

[0001] This utility model relates to the technical field of hinge double torsion spring machines, specifically a high-efficiency hinge double torsion spring machine. Background Technology

[0002] The double torsion spring machine is an automated piece of equipment specifically designed for producing double torsion springs, widely used in industries such as hardware, home appliances, and automotive parts. It employs a dual-rotation assembly and a spiral forming mechanism working in tandem to achieve simultaneous forming of the wire's end arms and the central U-shaped bend, ensuring the symmetry and consistency of the double torsion springs. However, the double torsion springs produced by this machine are exposed during production, and when observed by a user, they can easily fly out and impact the user, causing injury. Therefore, we have proposed a more efficient double torsion spring machine. Utility Model Content

[0003] The present invention aims to solve the problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows: a high-efficiency hinge double torsion spring machine, including a machine body, a protective cover, a front stop, a rear stop, fasteners and blocking components. A processing disc is arranged on the right side of the machine body. The protective cover is inserted through the outside of the processing disc. A first transparent plate is arranged on the protective cover. The front stop is hinged to the front end of the protective cover. The rear stop is hinged to the rear end of the protective cover. A second transparent plate is arranged on both the rear stop and the front stop. The fastener includes a limiting rod inserted through the front stop and a fastening rod arranged at the top of the limiting rod. The blocking component is arranged on the left side of the processing disc.

[0005] Preferably, the front end of the machine body is provided with a sealing door and heat dissipation holes, and a plurality of heat dissipation holes are arranged at equal intervals.

[0006] Preferably, a baffle is provided on the left side of the protective cover.

[0007] Preferably, both the rear door and the front door are provided with insertion holes, and the insertion holes are round holes.

[0008] Preferably, the fastening rod is inserted into the rear door through a socket, and the fastening rod is U-shaped.

[0009] Preferably, both of the blocking components include a stud disposed on the left side of the processing disc, a baffle plate inserted outside the stud, a rotating hole formed in the baffle plate, and a nut threadedly connected to the stud.

[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: The front and rear baffles of this utility model can rotate to cover the protective cover. After the cover is closed, the fastening rod of the fastener can be inserted into the insertion hole of the rear baffle, thereby fixing the front and rear baffles that cover the protective cover. The fixed protective cover can cooperate with the front and rear baffles to cover the processing structure of the machine body, avoiding the double torsion spring from flying out and causing certain injuries to the human body during processing, thus ensuring high safety. At the same time, the baffle can prevent the protective cover from moving further to the right. After being blocked, the baffle can be blocked by the baffle plate. After being blocked, the baffle can be fixed to the machine body by the cooperation of the nut and the stud. Thus, the protective cover can be fixed by the blocking component, achieving the effect of installation and disassembly, so as to facilitate maintenance and replacement of the protective cover.

It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] The following description, in conjunction with the accompanying drawings, describes some embodiments of this utility model that provide a high-efficiency hinge double torsion spring machine.

[0025] Example 1:

[0026] Reference Figure 1-5 This is the first embodiment of the present utility model, which provides a high-efficiency hinge double torsion spring machine, including a machine body 100, a protective cover 200, a front stop 300, a rear stop 400, a fastener 500, and a blocking member 600.

[0027] Specifically, the right side of the machine body 100 is provided with a processing plate 101, and the front end of the machine body 100 is provided with a sealing door 102 and a heat dissipation hole 103. Several heat dissipation holes 103 are arranged at equal intervals. During use, the processing plate 101 facilitates the installation of the protective cover 200 and facilitates the production of double torsion springs. The sealing door 102 provides a sealing effect, and the heat dissipation holes 103 allow for rapid heat dissipation so that the double torsion spring can function normally.

[0028] Specifically, the protective cover 200 is inserted on the outside of the processing tray 101. The protective cover 200 is provided with a first transparent plate 201 and a stop block 202 is provided on the left side of the protective cover 200. In use, the protective cover 200 provides protection to prevent the double torsion spring from flying out and causing certain injuries to the human body. The processing situation can be observed through the first transparent plate 201, and the stop block 202 can block the process so that the protective cover 200 can be installed.

[0029] Specifically, the front shutter 300 is hinged to the front end of the protective cover 200. In use, the front shutter 300 can block the right side of the protective cover 200, thus providing protection and preventing the double torsion spring from flying out and causing injury to the human body.

[0030] Specifically, the rear door 400 is hinged to the rear end of the protective cover 200. Second transparent plates 401 are evenly distributed on both the rear door 400 and the front door 300. Both the rear door 400 and the front door 300 have insertion holes 402, which are round holes. During use, the rear door 400 can block the right side of the protective cover 200, providing protection and preventing the double torsion spring from flying out and causing injury to the human body. The processing can be observed through the second transparent plates 401. Fasteners 500 can be installed on the rear door 400 through the insertion holes 402, and the front door 300 can be inserted and connected to the fasteners 500 through the insertion holes 402, thus securing the rear door 400 and the front door 300.

[0031] Specifically, the fastener 500 includes a limiting rod 501 inserted into the front deflector 300 and a fastening rod 502 disposed at the top of the limiting rod 501. The fastening rod 502 is inserted into the rear deflector 400 through the insertion hole 402. The fastening rod 502 is U-shaped. In use, the limiting rod 501 can move and rotate within the insertion hole 402 of the front deflector 300 so as to drive the fastening rod 502 to be inserted into the insertion hole 402 of the rear deflector 400 for fixation.

[0032] Specifically, the blocking member 600 is arranged on the left side of the processing plate 101. Both blocking members 600 include a stud 601 arranged on the left side of the processing plate 101, a baffle 602 inserted outside the stud 601, a rotating hole 603 opened on the baffle 602, and a nut 604 threadedly connected to the stud 601. In use, the baffle 602 can block the stop block 202, and then the baffle 602 can be fixed on the processing plate 101 by the cooperation of the nut 604 and the stud 601, so that the protective cover 200 can be fixed by the blocking member 600.

[0033] The working principle and usage process of this utility model are as follows: In use, first insert the protective cover 200 into the left side of the machine body 100. After insertion, move the protective cover 200 until the stop block 202 contacts the processing plate 101. Then loosen the nut 604 of the blocking member 600 and rotate the baffle 602 to block the stop block 202. Then tighten the nut 604. The protective cover 200 can be fixed on the processing plate 101 by the blocking member 600. Then rotate the front stop 300 and the rear stop 400 to cover the protective cover 200. After covering, move the limiting rod 501 of the fastener 500 upward and rotate the limiting rod 501 so that the fastening rod 502 is facing the insertion hole 402 on the rear stop 400. Then insert it. The front stop 300 and the rear stop 400 can be fixed by the fastening rod 502. After fixing, the protective cover 200 can provide protection.
