Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a strong pressure processing device for a spring. Background Art

[0002] The strong pressure treatment of the spring is to press the spring until the stress of the material layer exceeds the yield point, so that negative residual stress is generated on the surface and positive residual stress is generated in the core. There are two process methods. One is static strong pressure, which presses the spring to the required height and stops for 6-48 hours, and then releases it. This method occupies more process devices and equipment, and occupies a larger area, but the performance is more stable and it is suitable for some small springs. Another method is to press the spring to the specified height at a slower speed (about 1min), and then slowly release it (about 1min) to make the spring plastically deformed. Then stand it at this height. This method has the same effect as static strong pressure and is suitable for all kinds of large springs.

[0003] Publication number "CN210676782U" provides a spring pressing machine. When the spring needs to be pressed, the spring is sleeved on the sleeve rod, and then the sleeve rod is inserted into the sliding hole and the mounting block is slidably inserted into the mounting hole, the abutment block is rotated to insert it into the annular groove, and the mounting block is fixed in the mounting hole. At this time, the spring is located between the mounting seat and the support rod, and the driving member drives the mounting seat to slide on the slide rail along the length direction of the sleeve rod. At the same time, the spring abuts against the end wall of the support rod and the mounting block, and the spring is deformed to achieve strong pressing of the spring.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Firstly, the steps of the spring pressing machine in the process of disassembling and assembling the spring are too complicated, resulting in low convenience in disassembly and assembly. Secondly, the mounting seat in the spring pressing machine does not have a structure to block and limit it during the sliding process. As a result, during the process of extruding and pressing the spring, the staff cannot ensure that the mounting seat can be accurately controlled by the driving member to slide to the desired position every time. The sliding mounting seat needs to be continuously fine-tuned to slide it to the desired position. The practicality needs to be improved. Utility Model Content

[0028] A strong pressure component 5 is arranged on the upper end surface of the support box 4, and the strong pressure component 5 is used to perform strong pressure treatment on the spring 1 to be treated. A limit component 3 is arranged on the left side of the upper end surface of the operating table 2, and the limit component 3 is used to limit the leftward displacement range of the strong pressure component 5.

A limiting through hole 36 is provided on the lower side of the inner part of the push plate 53, and the limiting through hole 36 matches the limiting rod 31. The matching limiting through hole 36 and the limiting rod 31 can The blocking sleeve 33 can limit and guide the push plate 53 to prevent the push plate 53 from offsetting or shaking during the left and right displacement. The left side of the annular side of the limit rod 31 is provided with a blocking sleeve 33, and the blocking sleeve 33 can block and limit the leftward movement range of the push plate 53, so that the staff can match and adjust the leftward movement range of the push plate 53 according to the requirements of the strong pressure treatment.

The annular side of the limit rod 31 is provided with a scale line 311, and the scale line 311 is convenient for the staff to observe the required position of the blocking sleeve 33.

[0034] Working principle: During the strong pressure treatment of the spring 1 to be treated, the staff first controls the lifting electric push rod 512 to drive the blocking plate 56 to move down to the position through the connecting plate 59. At this time, the spring 1 to be treated can be placed horizontally and from left to right on the annular side of the center rod 55, and the right end of the spring 1 to be treated is inserted into the limiting cylinder 54. Then, the lifting electric push rod 512 is controlled to drive the blocking plate 56 to move up to the position through the connecting plate 59 (refer to Figure 1 or Figure 3), at this time, the electric hydraulic push rod 52 can be controlled to drive the push plate 53 to move to the left, so that the push plate 53 pushes the spring 1 to be processed to the left. When the spring 1 to be processed moves to the left and contacts with the blocking plate 56, the push plate 53 that continues to move to the left will squeeze the spring 1 to be processed for strong pressure treatment. In this process, the blocking sleeve 33 will block and limit the push plate 53 that moves to the left to prevent the push plate 53 from moving too far to the left and causing the spring 1 to be processed to be squeezed and damaged; when the spring 1 to be processed is subjected to strong pressure treatment, the electric hydraulic push rod 52 is controlled to drive the push plate 53 to move to the right to the initial position, and then the lifting electric push rod 512 is controlled to drive the blocking plate 56 to move down again through the connecting plate 59, so that the staff can put the spring 1 to be processed after the strong pressure treatment The processing spring 1 is moved to the left and removed; in the later use process, the staff only needs to loosen the fixing screw 32 with the help of an external wrench, and then the blocking sleeve 33 can be moved left and right. In this process, when the blocking sleeve 33 is moved to the left for adjustment, the leftward movement range of the push plate 53 will increase accordingly, so that the extrusion pressure of the push plate 53 on the spring 1 to be processed will also increase accordingly; when the blocking sleeve 33 is moved to the right for adjustment, the leftward movement range of the push plate 53 will decrease accordingly, so that the extrusion pressure of the push plate 53 on the spring 1 to be processed will also decrease accordingly, so that the staff can match and adjust the leftward movement range of the push plate 53 according to the strong pressure treatment requirements of the spring 1 to be processed of different lengths, and tighten the fixing screw 32 after the position adjustment of the blocking sleeve 33 is completed.
