Automatic pipe cutting machine

Abstract

The invention relates to an automatic pipe cutting machine and belongs to the technical field of pipe cutting equipment. The automatic pipe cutting machine mainly solves the problem that an existing pipe cutting machine is not suitable for cutting square pipes. The automatic pipe cutting machine is mainly characterized by comprising an automatic material storage and distribution frame, an automatic material taking mechanism, a material conveying rail, a material pushing system, a cutting system, a sizing and locating mechanism and a discharging frame, wherein the cutting system comprises an automatic clamping mechanism and an automatic cutting mechanism; the sizing and locating mechanism is composed of a sizing and locating box, a large guide rod, an upper girder, uprights, an oil cylinder and a large linear bearing; the sizing and locating box comprises a front panel, a rear panel, a small linear bearing, a small guide rod, a locating striking board, a spring pressing board, a spring clamp, a nut, a spring and a sensor; the uprights at the two sides of the sizing and locating mechanism are fixed to beams at the two sides of the upper end of the discharging frame respectively. The automatic pipe cutting machine has the advantages that the length of a product needing cutting is not limited, automatic material distribution, automation material taking, automatic material conveying and automatic clamping are achieved, and the automatic pipe cutting machine is mainly used for automatically cutting rectangular pipes.

Description

technical field [0001] The invention belongs to the technical field of pipe cutting equipment. In particular, it relates to an automatic pipe cutting machine which is especially suitable for cutting rectangular pipes. Background technique [0002] The raw material of the pipe material is automatically taken to the feeding track by the feeding mechanism on the storage and distribution rack of the automatic pipe cutting machine, and the pushing system automatically pushes it forward until it reaches the positioning and sizing mechanism on the blanking rack. The sizing mechanism accurately determines the sizing and positioning, and sends a signal to the controller, and the cutting system completes automatic clamping and automatic cutting. Each cut product is passed to the next process by the blanking rack or falls into the lower box of the blanking rack. Every time a pipe material is cut, its tail is pushed into the tail box, and in one case, it is automatically pushed into t...

AI Technical Summary

Problems solved by technology

[0003] At present, square pipe cutting is mainly manual cutting machine cutting and semi-automatic cutting, both of which have a high scrap rate, and the cut products have poor precision and poor product consistency.

Manual cutting has the disadvantages of high labor intensity, poor environment, potential safety hazards, large errors in cut products, and large saw kerfs.

Semi-automatic cutting has the following disadvantages: (1) Each tube material needs to be manually placed in the feeding fixture, and the head section of each tube material still needs to be manually positioned; (2) The material is fed from the second section of cutting The mechanism adopts servo, hydraulic, pneumatic and other power feeding methods. The length of each feeding is limited by the length of the linear guide rail, which does not exceed 500mm. When the product to be cut is long, it needs to be clamped and fed multiple times, which will affect the production efficiency and accuracy, and the efficiency is low. , the repeated positioning error is large, and it needs to be clamped and fed multip...
