Multi-head saw cutting device for pipes

Abstract

The invention discloses a multi-head saw cutting device for pipes. The multi-head saw cutting device comprises a horizontal machine base, wherein a guide rail is arranged on the horizontal machine base. The multi-head saw cutting device further comprises at least two saw cutting heads which are connected in series, wherein a base of each saw cutting head is directly or indirectly installed on a guide rail in a sliding mode, and a linkage mechanism is installed between every two adjacent bases. A sliding driving device for driving the saw cutting heads to slide is installed on the horizontal machine base, the sliding driving device is in transmission connection with the base of one saw cutting head, and a middle supporting guide mechanism used for supporting cut-off pipes is further installed between every two adjacent bases. A downstream supporting and guiding mechanism used for supporting the cut-off pipes is installed on the base of the saw cutting head located at the most downstreamposition in the pipe conveying direction. The multi-head saw cutting device can cut pipes shorter and is high in cutting efficiency.

Description

technical field [0001] The invention relates to a multi-head sawing device, which is used for online cutting of pipes. Background technique [0002] At present, the online cutting of pipes is achieved by using flying saws. As the name suggests, flying saws collect pulse signals through electrical measurement components, and use motors to drive the saw car to move along the conveying direction of the pipe. When the saw car reaches the speed of the required cutting material, it is synchronized Clamp to cut, then return to the original position, waiting for the next cut. [0003] However, there is a problem with the current flying saw. The saw car is driven by the motor to accelerate from a standstill to the same speed as the pipe conveying speed and then clamp and cut. After cutting, the clamp of the saw car loosens the pipe and then the sawing slows down to 0, and then the saw car reverses. After acceleration, decelerate and return to the initial position, which is convenien...

Problems solved by technology

[0003] However, there is a problem with the current flying saw. The saw car is driven by the motor to accelerate from a standstill to the same speed as the pipe conveying speed and then clamp and cut. After cutting, the clamp of the saw car loosens the pipe and then the sawing slows down to 0, and then the saw car reverses. After acceleration, decelerate and return to the initial position, which is convenient for sawing again. During the above-mentioned action cycle, the saw car is affected by the conveying speed of the pipe, the acceleration and deceleration of the saw car, and the current flying saw cannot cut more. For short pipes, it takes enough time for sawing to return to the initial position, which also limits the conveying speed of the pipes to not be too fast. Therefore, the current pipe manufacturers need to buy flying saws for online cutting, and then cut the pipes. The pipe is placed on a common sawing machine for secondary cutting

This requires the purchase of multiple sawing machines, resulting in increased costs and low sawing efficiency
