Description

Technical Field

[0001] The utility model belongs to the technical field of necking machines, and particularly relates to an automatic compensation telescopic mechanism of an automatic necking machine. Background Art

[0002] Automatic shrinking machine is an automated mechanical equipment specially used for shrinking various pipes and pipe fittings. It integrates advanced technology and automatic control system, and can complete shrinking operation efficiently and accurately. When working, the material is automatically transported to the designated position. Through the preset program and precise mold, the machine applies appropriate pressure and heat to it, so that the port of the pipe or pipe fitting shrinks as required, so as to achieve specific size, shape and performance requirements. This equipment is widely used in many fields, such as processing the shrinking part of the exhaust pipe in automobile manufacturing to ensure its close connection with other components; shrinking the metal pipe in pipeline engineering to adapt to complex installation environments; in the hardware manufacturing industry, it provides guarantee for the production of high-quality shrinking pipe fittings. The emergence of automatic shrinking machine has greatly improved production efficiency, ensured the consistency and precision of products, and reduced manual labor intensity and production costs.

[0003] In the current existing shrinking machine processing, it is usually held manually and then moved to the shrinking machine to assist in shrinking. With the advancement and development of science and technology, the existing technology has adopted an automatic mechanical feeding structure to assist in feeding. During use, the pipe is placed in the clamp of the automatic telescopic compensation mechanism. During the processing, the pipe is shrunken at this time. The resistance to push forward is relatively large. At this time, the large resistance is very likely to cause the pipe to be clamped and damaged. At the same time, its automatic feeding structure is not easy to disassemble and repair during use. If the motor or the clamp structure on the top is damaged, it is usually necessary to remove the bolts for inspection and maintenance. It can be seen that the disassembly and maintenance during the overall application period is relatively cumbersome and inconvenient, so it needs to be improved. Utility Model Content

[0029] Principle and advantages of use: By setting the driving mechanism 3, the device can be operated by starting the driving motor 322 during use, and the driving motor 322 drives the gear 323 to rotate, and the gear 323 and the rack 321 are meshed for transmission, and the slide 33 can be driven to slide and displace on the slide rail 31. At this time, the sliding displacement of the slide 33 can assist in flexibly driving the clamp 7 to move laterally, and the product to be processed is placed on the inner side of the clamp 7, and the clamp 7 assists in clamping and positioning. At this time, the driving motor 322 can drive the clamp 7 to move toward the necking machine body 2, and the clamped product can be automatically moved to the necking machine body 2. At this time, the device can be automated for production and processing, and the spring buffer 5 assists in automatic expansion and contraction during the processing. When the resistance is large, the spring buffer 5 contracts, and then when the resistance is small, the spring buffer 5 extends to reset and push to continue walking, ensuring that the product can be formed and the pipe will not be clamped, which can improve the stability of the overall production and processing of the device;

[0030] By setting up the mounting mechanism 6, during use of the device, the gear 323 can be rotated to fit the tooth groove of the rack 321. At this time, the top plate 4 is covered on the top of the slide rail 31, and the limit block 66 is inserted into the inner side of the limit groove 62. At this time, the limit spring 64 can be reset to drive the slider 65 to move inward. The inward movement of the slider 65 can drive the clamping block 68 to be inserted into the inner side of the clamping groove 67. The clamping block 68 and the clamping groove 67 are mutually engaged, which can assist in limiting the limit block 66 and clamping it to the inner side of the limit groove 62. At this time, the entire base plate 1 and the top structure thereof can be installed on the top of the slide frame 33. If disassembly and maintenance are required, the push frame 615 can be moved by pressing the push plate 63. The movable frame 615 can be displaced to drive the linkage block 611 to slide on the inner side of the linkage rail 610. The movement of the linkage block 611 can drive the linkage frame 612 to contact the inclined surface of the guide block 613. The roller 614 at the inner end of the linkage frame 612 can contact the guide block 613, thereby assisting the guiding activity, and can prompt the push plate 69 to move inward to drive the slider 65 to retract toward the inner side of the top rail 61. The inward movement of the slider 65 can drive the card block 68 to retract from the inner side of the card slot 67. At this time, the limit block 66 is located inside the limit slot 62 and loses its limit, so that the top plate 4 and the structure on its top can be quickly disassembled and assembled, so that the device as a whole is convenient for quick inspection and maintenance, and the overall ease of use of the device can be improved.
