Problems solved by technology

[0004] The traditional domestic pipe row positioning device has no energy absorbing device, which is a "hard-to-hard" impact method, which makes the steel pipe rebound after hitting the positioning device, resulting in inaccurate positioning, which seriously affects the positioning accuracy and the sawing effect and efficiency of the saw machine.
In addition, the fixed length of the pipe row positioning device is limited by the structural design and cannot be adjusted arbitrarily
The pipe row positioning device imported from abroad, the energy absorbing device is a hydraulic circuit composed of an accumulator and a control valve block, and this circuit needs to be connected with an external high-pressure hydraulic system, the structure is complex, and it is inconvenient to adjust

Abstract

The invention belongs to the technical field of mechanical engineering, relates to a row saw cutting device, in particular to a saw cutting device for tube rows with positioned length. The saw cutting device mainly consists of a walking rail track and a row sawmill. A positioning device body consists of a car frame, a walking driving mechanism, a locking mechanism, a walking guide mechanism, a positioning mechanism, a buffering baffle plate and a swing mechanism of the buffering baffle plate, wherein the buffering baffle plate is connected with the car frame through an auxiliary sliding hinge point; two gas-liquid buffers and a response hydraulic cylinder are arranged in the baffle plate, and the gas-liquid buffers and the head of the hydraulic cylinder are simultaneously connected with the working face of the baffle plate. The invention has the advantages of elaborate structure, simple operation, simple control, high length positioning precision and energy saving. The lumber recovery of steel tubes can be increased, and the length positioning requirement of any length can be realized. The invention can be popularized to be applied to the saw cutting or cutting device with positioned length for sectional material, bar material and the like.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, and relates to a row sawing device in the production of steel pipes, in particular to a tube row sawing device to a fixed length. Background technique [0002] Almost all hot-rolled steel pipes have to go through a finishing sawing process after cooling. The sawing methods include single sawing and row sawing, and the operation efficiency of row sawing is several times that of single sawing. . Therefore, the sawing of steel pipes in rows is widely used. [0003] The pipe row precise positioning device is used before and after the steel pipe finishing row sawing machine, and is used for precise positioning along the length direction of the steel pipe when cutting the head, tail and length of the pipe row. [0004] The traditional pipe row positioning device in China has no energy absorbing device, which is a "hard-to-hard" impact method, which makes the steel pipe rebound after hi...
