Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a production device for springs that is convenient for adjusting the truncation length. Background Art

[0002] A spring is a mechanical part that utilizes elasticity. A part made of elastic material deforms under the action of an external force and returns to its original state after the external force is removed. After being wound and formed in spring processing, the two ends of the spring have a spiral lift angle and cannot be placed vertically stably. It is necessary to grind the ends of the spring flat. When processing larger springs, in order to improve production efficiency, generally, the end faces of both ends of the spring are first cut flat by a spring cutting machine, and then grinding is carried out.

[0003] For a spring production and processing device, precise positioning cutting is required during processing. However, the existing spring cutting devices are usually not convenient for adjusting the cutting length when cutting springs, which is time-consuming and laborious for spring production and processing, and cannot meet the requirements of customers, greatly reducing production efficiency.

[0024] Referring to Figure 1-2 , a production device for springs that is convenient for adjusting the truncation length, including a support 1, a first support 2 and a second support 3 that are installed on the support 1 and connected to each other, and a truncation mechanism installed on the support 1. The truncation mechanism includes a limiting component, an adjusting component and a truncation component;

[0025] The limiting component includes a first limiting part 4, a second limiting part 5, a second cylinder 11 and a pressing part 12. The second limiting part 5 and the first limiting part 4 respectively penetrate the upper and lower end plates of the second support 3 and are both fixedly arranged with the first support 2, and there is a gap between the first limiting part 4 and the second limiting part 5. The second cylinder 11 is installed inside the second support 3, and the pressing part 12 is installed at the output end of the second cylinder 11 and moves along the chute of the second support 3;

[0026] The adjusting component is installed in the middle of the support 1 and includes an electric cylinder 6 and a support table 7. The support table 7 is installed at the output end of the electric cylinder 6, and its output end can extend upward from the notch of the support 1;

[0027] The truncation component includes a first cylinder 8, a guide rail 9 and a cutting knife 10. The first cylinder 8 is installed inside the first support 2, the cutting knife 10 is fixed at the output end of the first cylinder 8, and slides inside the first support 2 through the guide rail 9;

[0028] Put the spring down from the second limiting part 5, and the bottom of the spring abuts against the support table 7. Then, according to the required length of the spring to be cut, start the electric cylinder 6 to push the support table 7 up or down to a suitable position until the pre-truncation position of the spring is at the horizontal height position of the cutting knife 10. Then drive the second cylinder 11 to push the pressing part 12 to enter from one side opening of the second limiting part 5 and the first limiting part 4, apply pressure to one side of the spring, at this time the spring is restricted from moving, and then drive the first cylinder 8 to push the cutting knife 10 to move along the guide rail 9, and press and truncate the spring through the cutting knife 10;

[0029] After the spring is truncated, the electric cylinder 6 can be driven to pull the support table 7 downwards, so that the truncated spring can be taken out from the opening at the lower end of the first limiting part 4. When truncating the subsequent springs, only the above operations need to be repeated.

[0030] Notches are provided on the sides of the first limiting part 4 and the second limiting part 5 close to the pressing part 12. The width of the notch is adapted to the width of the pressing part 12, and the lower end of the first limiting part 4 is semi-open; the pressing part 12 can enter from the opening on one side of the first limiting part 4 and the second limiting part 5 to apply pressure to the spring, avoiding the phenomenon of shaking when the spring is cut. Moreover, the width of the sliding groove provided on the upper and lower end plates of the second bracket 3 is adapted to the width of the pressing part 12, which can ensure the stable movement of the pressing part 12 and enable the pressing part 12 to accurately enter the first limiting part 4 and the second limiting part 5.

[0031] The diameter of the support platform 7 is adapted to the inner diameter of the first limiting part 4; the support platform 7 can support the spring, move up and down in the first limiting part 4 to adjust the position. After the spring is cut, the electric cylinder 6 can be driven to pull the support platform 7 downward, so that the cut spring can be taken out from the opening at the lower end of the first limiting part 4.

[0032] The cutting knife 10 and the second cylinder 11 are arranged at the same horizontal height, and the fixing block arranged in the middle where the pressing part 12 is located is also at this height; after the pressing part 12 applies pressure to limit the spring, the first cylinder 8 pushes the cutting knife 10 to cut the spring. At this time, the cutting knife 10 will touch the pressing part 12, and the output end of the second cylinder 11 is fixed to the middle of the pressing part 12. Installing a fixing block in the middle of the pressing part 12 can increase the overall force on the pressing part 12, facilitating the cutting of the spring.
