All-in-one machine for chipless cutting of plastic pipes

Abstract

The invention discloses a dual-traction chipless cutting machine applied to production of plastic pipes. An upper track, a lower track and a cutter are respectively fixed onto a rack, the upper track is used for pressing and releasing the pipes through a pressing assembly, the height of the lower track can be regulated by a lifting assembly so as to adapt to production of pipes of different specifications and guarantee that a traction center and a cutter center are on one straight line, a synchronous chain wheel is internally provided with a regulation clutch, is arranged on the lower track and is connected with the cutter to form a whole body through a synchronously chain so as to realize synchronization of a tractor and the cutter, a spring self-tension device is arranged at a tension chain wheel and can be used for guaranteeing automatic tension of the chain during production of different pipes, and a return cylinder is fixed onto the rack and is used for resetting the cutter after cutting action is finished, thereby realizing synchronism of the tractor and the cutter and guaranteeing stability of traction and cutting.

Description

technical field [0001] This patent belongs to the field of extrusion auxiliary machinery, in particular to a dual traction chipless cutting integrated machine for extrusion production of plastic pipes. Background technique [0002] At present, the haul-off machine and cutting machine used for the production of plastic pipes have the following disadvantages: 1. The haul-off machine and the cutting machine are split, and the synchronization between traction and cutting is very poor, and the production cannot be carried out normally during high-speed production; 2. Most of the crawlers under the haul-off machine are Fixed type, it is impossible to adjust the center position of the lower track according to different pipe specifications, and the operability is not strong; 3. The synchronization device of the cutting machine mostly uses cylinder synchronization, and the production of pipes with different specifications needs to adjust the pressure of the cylinder, which affects...

AI Technical Summary

Problems solved by technology

[0003] The invention solves the shortcoming that the pulling and cutting of double-outlet plastic pipes cannot be synchronized in the prior art. The invention adopts a mechanical synchronization method to realize the complete synchronization of pulling and cutting, and can solve the problem of the cutting machine running at high speed during pipe extrusion production. The problem of high acceleration and fast acceleration at startup
