Multi-head pipe cutter

Abstract

The invention relates to the technical field of pipe-shaped material machining, in particular to a multi-head pipe cutter which is provided with a plurality of pipe cutting units and can be used for cutting pipe-shaped materials simultaneously. The multi-head pipe cutter comprises a rack, a pushing device, a power device and at least two sets of pipe cutting units. The power device, the pushing device and the pipe cutting units are all mounted on the rack. Each pipe cutting unit comprises a transmission device and a cutting device, wherein the cutting device is mounted on the transmission device. The power device can drive the cutting devices through the transmission devices. The number of the pushing device is only one, and the pushing device is simultaneously connected with the transmission devices in all the pipe cutting units and can push the cutting devices through the transmission devices. Compared with the prior art, only one pushing device is needed in the entire pipe cutter, the structure is simplified, the failure rate is greatly lowered, more importantly, the synchronicity of the pushing process is guaranteed, and the cutting speed is improved to a great extent.

Description

technical field [0001] The invention relates to the technical field of tubular material processing, in particular to a multi-head pipe cutting machine with a plurality of pipe cutting units for simultaneously cutting tubular materials. Background technique [0002] In the processing industry of pipes, especially metal pipes, it is often necessary to cut the pipes according to certain size requirements. This simple and repetitive work was completely done by manual cutting in the early days. Subsequently, equipment specially used for cutting pipes appeared on the market, that is, pipe cutting machines. [0003] This kind of pipe cutting machine mainly includes a frame on which a set of pipe cutting unit is installed, mainly including a motor, a worm gear and a saw blade. The processed pipe is sent to the saw blade for section-by-section cutting. Although this cutting machine has realized a certain degree of automation, it can only cut one section at a time. If a pipe needs ...

Problems solved by technology

But its defects are also obvious: firstly, each set of its push mechanism needs to be equipped with a push cylinder, which is very costly; secondly, as long as one push cylinder breaks down, it has to be shut down for repairs, therefore, the more push cylinders , the corresponding failure rate is also higher; finally, and most importantly, the pushing stroke of each hydraulic cylinder is independent, it is difficult to adjust to a fully synchronized state, and then it is impossible for multiple cutting mechanisms to complete the cutting synchronously. However, the pipe cutting machine can only proceed to the next round of cutting after all the cutting work is completed, which leads to the cutting speed of the entire equipment being based on the speed of the slowest cutting unit. This "short board effect" greatly affects the equipment. The pipe cutting speed cannot maximize the advantages of the multi-head pipe cutting machine
