Description

Technical Field

[0001] The present application relates to the technical field of bending torsion spring ends, and in particular to a bending and shaping mechanism of torsion spring processing equipment. Background Art

[0002] In many mechanical devices, torsion springs must be mounted on specific structures. For example, in small mechanical switches, the ends of the torsion springs are bent to fit into the switch's slots. Bending the ends of the torsion springs allows for precise installation, reducing or preventing problems such as displacement or falling off during use.

[0003] The existing bending of the torsion spring ends generally adopts a bending machine to assist in bending. However, the existing bending machine is only capable of bending one end of the torsion spring. When both ends need to be bent, the first end needs to be bent first and then removed before bending the next end. This bending method is prone to the problem of incorrect bending direction due to lack of concentration. At the same time, due to the lack of corresponding shaping mechanism, the error in the length after bending is too much during the bending process of the two ends, which affects the use.

[0004] The above content is only used to assist in understanding the technical solution of this application and does not constitute an admission that the above content is prior art. Utility Model Content

The second cylinder is arranged on the workbench, the output end of the second cylinder is connected to the connecting plate, and the positioning rod is arranged on the connecting plate.

[0011] As a preferred solution of the present application, the clamping assembly includes a guide groove, a spring and a pressure block. The guide groove is provided on the sliding frame, the pressure block is slidably connected to the guide groove, and the spring is provided between the guide groove and the pressure block.

[0012] As a preferred solution of the present application, the pad is provided with a groove that is adapted to the size of the torsion spring end.

[0014] As a preferred solution of the present application, a limiting ring is further included, and the limiting ring is provided on the positioning rod.

[0015] The bending and shaping mechanism of the torsion spring processing equipment provided by the present application, when in use, can play the role of preliminary positioning of the torsion spring by placing the two end parts of the torsion spring on the placement component, and then use the positioning component to penetrate the spiral part of the torsion spring to further shape and position the torsion spring, ensuring that the torsion spring does not fall off when bending at both ends. At the same time, the position of the torsion spring after placement can be fine-tuned to ensure that the lengths of the two end parts of the torsion spring on the placement component are consistent. After the placement is completed, the positioning rod, torsion rod and drive component are used to achieve simultaneous bending of both ends of the torsion spring. Compared with the traditional single-end bending machine, the bending efficiency is higher. Furthermore, since both sides are bent at the same time, there is no need to remove the torsion spring, which can avoid the problem of incorrect bending angle due to wrong direction placement after the torsion spring is removed.

[0028] Furthermore, it also includes a control panel and a control box. The workbench 2 is provided with a control panel, which is electrically connected to the control box provided on the base 1 , and the control box is electrically connected to the positioning component 4 and the driving component 7 .

[0029] It can be understood that the bending and shaping mechanism of the torsion spring processing equipment provided by the present application, when in use, can play the role of preliminary positioning of the torsion spring by placing the two end parts of the torsion spring on the placement component 3, and then use the positioning component 4 to penetrate the spiral part of the torsion spring to further shape and position the torsion spring, ensuring that the torsion spring does not fall off when bending at both ends. At the same time, the position of the torsion spring after placement can be fine-tuned to ensure that the lengths of the two end parts of the torsion spring on the placement component 3 are consistent. After placement is completed, the positioning rod 403, the torsion rod 6 and the drive component 7 are used to achieve simultaneous bending of both ends of the torsion spring. Compared with the traditional single-end bending machine, the bending efficiency is higher. Furthermore, since both sides are bent at the same time, there is no need to remove the torsion spring, which can avoid the problem of incorrect bending angle due to incorrect placement of the torsion spring after removal.

[0030] For details, please refer to Figure 1 , Figure 4 , Figure 5 On the basis of the above embodiment, it also includes a lifting component 8 and a clamping component 9. The lifting component 8 is connected to the clamping component 9. The lifting component 8 is composed of two first cylinders 801 and a sliding frame 802. The two first cylinders 801 are arranged on the workbench 2, and a sliding frame 802 is connected between the output ends of the two first cylinders 801, and a clamping component 9 is arranged on the sliding frame 802; further, the clamping component 9 includes a guide groove 901, a spring 902 and a pressing block 903. The sliding frame 802 is provided with a guide groove 901, and the pressing block 903 is slidably connected to the guide groove 901, and a spring 902 is provided between the guide groove 901 and the pressing block 903; it can be understood that by setting the clamping component 9, the end part of the torsion spring can be clamped and fixed, thereby reducing the situation where the torsion spring shakes excessively or falls during the bending process.

[0031] For details, please refer to Figure 3 , Figure 5On the basis of the above embodiment, the placement component 3 includes a placement block 301 and a pad 302. The placement block 301 is set on the workbench 2, and the placement block 301 is provided with a pad 302. The pad 302 is used to place the end of the torsion spring; further, the pad 302 is provided with a groove that is adapted to the size of the end of the torsion spring 902. It can be understood that by setting the groove, the end of the torsion spring can be partially placed therein to achieve the effect of preliminary positioning.

[0032] For details, please refer to Figure 1 , Figure 3 Based on the above embodiment, the driving assembly 7 includes a motor 701, a rotating shaft 702 and a bevel gear set 703. The motor 701 is arranged on the base 1, one end of the rotating shaft 702 is connected to the torsion rod 6, and the other end of the rotating shaft 702 is connected to the base 1. The rotating shaft 702 is connected to the output shaft of the motor 701 through a bevel gear.

[0033] For details, please refer to Figure 1 , Figure 3 Based on the above embodiment, the positioning assembly 4 includes a second cylinder 401, a connecting plate 402 and a positioning rod 403. The second cylinder 401 is arranged on the workbench 2, and the output end of the second cylinder 401 is connected to the connecting plate 402, and the positioning rod 403 is arranged on the connecting plate 402.

[0034] For details, please refer to Figure 1 , Figure 3 On the basis of the above embodiment, the horizontal plane of the pad 302 is higher than the horizontal plane of the placement block 301. It can be understood that the height of the pad 302 is higher than the placement block 301, which can avoid the rigid contact between the placement block 301 and the surface of the pressure block 903. At the same time, the pad 302 is made of flexible materials such as rubber, which can play a role in buffering and shock absorption.

[0035] For details, please refer to Figure 3 On the basis of the above embodiment, a limiting ring 10 is further included. The limiting ring 10 is set on the positioning rod 403. By setting the limiting ring 10, the movement of the torsion spring can be effectively limited.

[0036] In summary, when the bending and shaping mechanism of the torsion spring processing equipment is in use, the two end parts of the torsion spring are respectively placed on the grooves of the pad 302, and then the second cylinder 401 is started through the control panel on the workbench 2. The second cylinder 401 drives the positioning rod 403 to move, and the positioning rod 403 extends into the spiral part of the torsion spring. At this time, the fine adjustment of the torsion spring position is completed to ensure that the protruding lengths of the two ends of the torsion spring placed on the pad 302 are consistent. Then the first cylinder 801 is started. During the retraction process of the first cylinder 801, the sliding frame 802 is driven to move in the direction close to the torsion spring, and the rubber pad on the pressure block 903 is used to contact the surface of the torsion spring and press the end part of the torsion spring. Finally, by starting the two motors 701 on the base 1, the torsion rod 6 is driven to rotate. The torsion rod 6 squeezes the end part of the torsion spring during the rotation, and is combined with the fixed rod 5 to achieve simultaneous bending of the two ends of the torsion spring. Through the above settings, compared with the traditional torsion spring single-end bending mechanism, the present application can have higher bending efficiency and higher accuracy after bending.
