Problems solved by technology

The existing equipment relies on the manual operation of workers to realize the rotation of the tube blank; the workers manually move and lift the tube blank according to the measured node height. The accuracy cannot be guaranteed, and the quality of the produced bellows is also difficult to meet the technical requirements of the compensator

Embodiment Construction

[0016] see figure 1 , The composition of the present invention includes a base 22, a central shaft 15, an expansion device 12, a tube blank tray 8, an indexing device, and a feeding device. The tube blank 11 to be processed is fixed on the tube blank tray 8, and each wave node is sequentially processed by the expansion device 12.

[0017] see figure 1 , image 3 , when the bulging device bulges, the tube blank will produce a non-round straight edge section, which needs to be rotated for multiple times to form the tube blank. The indexing device is a device used to replace manual rotation. The indexing device comprises an indexing motor 14, a transmission mechanism, and a chassis 4, a tray 5, and a rotating bracket 6 arranged in sequence from bottom to top. The tray 5 is set on the central shaft 14 of the molding machine and fixed with the chassis 4 . The top of the rotating bracket is fixed with the tube blank pallet 8, and the bottom is fixed with the pallet 5. The trans...

Abstract

A large corrugated pipe forming machine is used to solve the problem of automatic production of large corrugated pipes. The composition includes a base, a central shaft, an expanding device and a tube blank tray, and the special feature is that the machine also includes an indexing device and a feeding device. The indexing device is located at the lower part of the tube blank tray. The frame is fixed to the tube blank tray, and the rotating bracket drives the tube blank tray to shift; the feeding device is located at the lower part of the indexing device and the upper part of the base, and the two lifters of the feeding device are fixed to the chassis of the indexing device, and the lifter drives the indexing The device moves up and down together with the tube blank tray. The invention can greatly reduce the labor intensity of workers, effectively improve work efficiency, realize accurate indexing, accurate feeding, and improve the processing quality of large bellows.

Description

technical field [0001] The invention relates to corrugated pipe manufacturing equipment, in particular to a large-scale corrugated pipe forming machine with a high degree of automation. Background technique [0002] The bellows compensator is a pipeline thermal compensation component used in various industries such as metallurgy, mining, and heat pipe network. The bellows is the core component of the bellows compensator. The processing of bellows is carried out on a bellows forming machine. At present, many corrugated pipe manufacturers are still using equipment with backward technology, especially the processing of large corrugated pipes, which still needs manual operation in many links. For example, during the forming process of a large bellows, it is necessary to sequentially process the corrugated nodes on the tube blank through the expansion of the forming mold. When the mold bulges, a non-circular straight edge section will be produced, and the tube blank needs to be ...
