Description

Technical Field

[0001] The utility model relates to the technical field of spring heat treatment, in particular to a compression shaping device before spring heat treatment. Background Art

[0002] Compression shaping of the spring before heat treatment can make its internal structure more stable and improve the mechanical properties and durability of the spring.

[0003] After searching, the patent number CN219988541U discloses a spring compression shaping device before heat treatment. The shaping device puts the spring on the surface of the spring sleeve rod, and installs the spring extrusion plate through the threaded connection between the threaded rod and the threaded sleeve. After the spring installation mechanism is placed on the surface of the limit bracket, the hydraulic telescopic machine is operated. When the hydraulic telescopic machine is running, it can squeeze the sliding seat to move laterally. When the sliding seat moves, it can drive the spring installation mechanism to slide laterally by driving the limit bracket. When one side of the spring extrusion plate moves to the surface of the fixed pressure seat, the limit bracket can squeeze and compress the shaping bottom plate.

[0004] However, the spacing between the multiple sleeve rods used to place the springs in the above device is fixed. When the width range of the spring to be compressed is large, the arrangement of the sleeve rods will affect the stable placement of the spring and reduce the stability of the spring during compression.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a spring compression shaping device before heat treatment.

[0026] Example 1

[0027] The utility model provides Figure 1-3 A spring pre-heat treatment compression setting device shown comprises a base frame 1, a hydraulic cylinder 2 is fixedly arranged on the inner side of the base frame 1, a cross bar 3 is fixedly arranged at the end of the output shaft of the hydraulic cylinder 2, an extrusion plate 4 is fixedly arranged at the end of the cross bar 3, a mounting frame 5 is fixedly arranged at the top end of the base frame 1 away from the hydraulic cylinder 2, a support plate 6 is fixedly arranged on the side wall of the mounting frame 5, a plurality of moving holes 7 arranged in a symmetrical manner are opened inside the extrusion plate 4 and the support plate 6, a sleeve rod 8 is arranged inside the moving hole 7, a telescopic plate 17 is fixedly sleeved on the outer wall of the sleeve rod 8, and the telescopic plate 17 is fixedly connected to the hole wall of the moving hole;

[0028] The rod wall of the cross bar 3 is rotatably sleeved with an externally threaded tube 9, and the externally threaded tube 9 and the cross bar 3 are rotatably matched through a damping bearing. The tube wall thread sleeve of the externally threaded tube 9 is provided with a movable plate 10, and a connecting plate 11 is fixedly provided at the end of the sleeve rod 8. A plurality of push plates 12 symmetrically arranged in a circular pattern are rotatably provided between the movable plate 10 and the plurality of connecting plates 11. Both ends of the push plate 12 are rotatably connected to the inner wall of the groove and the outer wall of the connecting plate 11 through an axle pin, and a groove for cooperating with the push plate 12 for rotation is provided on the outer wall of the movable plate 10.

[0029] Before compressing and shaping the spring, the width range of the spring is measured, and the spacing between the multiple sleeve rods 8 is adjusted according to its width. First, the external threaded tube 9 needs to be rotated so that the external threaded tube 9 rotates around the cross bar 3 and drives the movable plate 10 to move laterally. At this time, with the rotation cooperation of the push plate 12, the groove and the connecting plate 11, and through the connection limit of the telescopic plate 17, when the movable plate 10 moves laterally, the multiple sleeve rods 8 can slide in the moving hole 7. At this time, the distance between the multiple sleeve rods 8 can be adjusted, and then the spring is put on the sleeve rod 8, and the hydraulic cylinder 2 is started, so that the hydraulic cylinder 2 pushes the extrusion plate 4 forward through the cross bar 3. Since the supporting plate 6 is also provided with a moving hole 7, the sleeve rod 8 can pass through the supporting plate 6, and the spring is compressed and shaped by the cooperation of the extrusion plate 4 and the supporting plate 6.

[0030] Example 2

[0031] Embodiment 2 is based on Embodiment 1, in order to prevent the external threaded tube 9 from rotating as much as possible after the position of the sleeve rod 8 is adjusted. Figure 1-2 As shown, an annular groove is provided on the outer wall of the externally threaded tube 9, a swivel 13 is rotatably provided in the annular groove, a positioning rod 14 is slidably passed through the outer wall of the swivel 13, a pressing plate 15 is fixedly provided at the end of the positioning rod 14, a spring 16 is sleeved on the rod wall of the positioning rod 14, and the two ends of the spring 16 are respectively fixedly connected to the positioning rod 14 and the swivel 13, a plurality of positioning grooves symmetrically arranged in a surrounding manner are provided on the inner wall of the annular groove, and the positioning rod 14 is matched with the positioning grooves.

[0032] Since the external threaded tube 9 and the cross bar 3 rotate through the damping bearing, it is relatively difficult to rotate the external threaded tube 9. At the same time, the swivel 13 cannot drive the external threaded tube 9 when it is not pressed due to the rotation cooperation of the external threaded tube 9. At this time, the external threaded tube 9 can be protected from accidental pushing. When it is necessary to rotate the external threaded tube 9, the pressing plate 15 can be squeezed while holding the swivel 13, so that the pressing plate 15 drives the positioning rod 14 to be inserted into the positioning groove. At this time, the swivel 13 is connected to the external threaded tube 9, and the external threaded tube 9 can be driven to rotate through the swivel 13.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
