Description

TECHNICAL FIELD

[0001] The utility model belongs to PPR tubular product processing technical field, and specifically relates to a tubular product pressing device for tubular product cutting machine. BACKGROUND

[0002] In the cutting operation process of PPR tubular product, currently, many technical problems to be solved are faced. On the one hand, due to the existence of certain dimensional tolerance in the production process of tubular product, inevitable gap exists between the outer diameter size of tubular product and the clamp used. This gap makes tubular product unable to realize close and stable adhesion when being fixed by the clamp, thereby burying unstable factors for subsequent cutting operation. On the other hand, in the layout of the existing cutting equipment, the spacing between the cutting machine and the traction machine and the turnover table is not reasonable, and the distance is too large. This makes tubular product lack sufficient and effective support in the process of being transmitted from the traction machine to the cutting machine and then to the turnover table, and further causes tubular product to easily appear bending phenomenon.

[0003] When being in the cutting state, the above problems can cause tubular product to produce shaking. With the continuous operation of cutting, in the case of more serious situation, tubular product can appear violent jumping. This shaking and jumping have great negative influence on the processing quality and production process of tubular product. First, it seriously affects the flatness of tubular product cut, so that the port of tubular product after cutting is difficult to meet the process requirements of high precision, and increases the difficulty and cost of subsequent processing procedure. Secondly, when tubular product jumps, the port of tubular product can collide with the clamp. This collision not only causes physical damage to the port of tubular product and the clamp, shortens the service life of the equipment, but more seriously, the impact force generated by the collision can trigger the stop protection mechanism of the equipment, causing the equipment to stop. The frequent stop of the equipment seriously interferes with the continuity and stability of production, greatly reduces the production efficiency, increases the production cost, and seriously affects the overall benefit of production operation.
