Pipe cutting device for machining pipe fittings with different pipe diameters

Abstract

The invention discloses a pipe cutting device for machining pipe fittings with different pipe diameters. The pipe cutting device for machining the pipe fittings with the different pipe diameters comprises a rotary cutter holder and a cutter feeding sleeve, wherein one end of the rotary cutter holder is provided with a pipe cutting assembly and a pipe supporting assembly; a gap for a to-be-processed pipe fitting to pass through is formed between the pipe cutting assembly and the pipe supporting assembly; multiple sets of adjusting paths which are distributed in the radial direction and have different lengths are arranged on the cutter feeding sleeve; adjusting grooves formed in the inner side wall of the cutter feeding sleeve are formed in the two ends of each set of adjusting paths; the adjusting grooves are used for containing and positioning the pipe cutting assembly and the pipe supporting assembly respectively, so that the sizes of gaps between the pipe cutting assembly and the pipe supporting assembly which are located on different adjusting paths are different; the adjusting paths with different lengths are selected to change the sizes of the gaps between the pipe cutting assembly and the pipe supporting assembly, so that the pipe cutting device can machine pipe fittings with the different pipe diameters; and the multiple sets of adjusting grooves with different groove depths are designed in the cutter feeding sleeve, so that the pipe cutting device can machine the pipe fittings with the different pipe diameters, parts do not need to be replaced when the pipe cutting device is used, and the pipe cutting device is convenient to use.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a pipe cutting device for processing pipe fittings with different pipe diameters. Background technique [0002] In the general processing of metal pipe fittings such as copper pipes and aluminum pipes, in order to meet the needs of pipe fitting design, in addition to bending processing steps such as bending the shape of specific parts of the pipe fittings, it also includes the length of the pipe fitting design. In the cutting step, in order to carry out the above-mentioned pipe cutting step, it is commonly used to use a set of pipe cutting devices to perform the pipe cutting operation. [0003] As shown in Figure 1, the existing pipe cutting device includes a rotating seat 1A, a cutter head 2A, a supporting wheel 3A and a knife feed sleeve 4A.

Problems solved by technology

[0003] As shown in Figure 1, the existing pipe cutting device includes a rotating seat 1A, a cutter head 2A, a supporting wheel 3A and a knife feed sleeve 4A. The processing gap 5A that can accommodate the steel pipe inside, the two supporting rollers 3A fix the pipe fittings, the cutter head 2A rotates to cut the steel pipe, the cutter head 2A and the two supporting rollers 3A are installed on the rotating seat 1A through the radial moving block, and the radial moving block The movement of the tool is driven by the feeder sleeve 4A, and the movement of the radial moving block can realize the reduction of the processing gap 5A formed between the cutter head 2A and the support wheel 3A, thereby realizing the cutting of the pipe fittings. The rotation of the rotating seat 1A is driven by the motor. Now In order to save cost and investment, the current long U pipe bender can realize the processing of pipe fittings with different pipe diameters. In order to make the pipe cutting device match the processing of pipe fittings with corresponding pipe diameters, the current routine operation is to replace the corresponding pipe fittings on the long U pipe bender. The pipe cutting device (specifically, replace the corresponding feeder sleeve and the corresponding radial moving block) so that the pipe cutting device can adapt to the processing of pipe fittings with different pipe diameters, but because the entire pipe cutting device needs to be replaced, the replacement time is long, It needs to be adjusted after the replacement, which will slow down the production progress and make the production efficiency low. Moreover, it is necessary to manufacture a set of special pipe cutting devices according to the size of the pipe fittings of each pipe diameter, which makes the production cost high; in addition, the existing The pipe cutting device uses two support rollers 3A to fix the pipe fittings to ensure that the pipe fittings are fixed more stably, but the use of two support rollers 3A to fix the pipe fittings makes the structure of the pipe cutting device complicated, and the radial moving block is generally installed in the sliding groove of the rotating seat. The use of multiple radial moving blocks will increase the processing difficulty of the rotating seat, thereby increasing the manufacturing cost. In addition, the support rollers are fixed by bolts. When replacing the support rollers, all the bolts need to be unscrewed. It is troublesome to replace, and the later maintenance cost is high
