Automatic hole opening machine for large-diameter plastic winding pipe and hole opening method of automatic hole opening machine

Abstract

The invention discloses an automatic hole opening machine for a large-diameter plastic winding pipe and a hole opening method of the automatic hole opening machine. The automatic hole opening machinefor the large-diameter plastic winding pipe comprises a frame, a first three-axis linkage device, a milling cutter and an auxiliary hole opening device, wherein the first three-axis linkage device isassembled on the frame and is used for controlling hole milling positioning of the milling cutter, the milling cutter is fixed onto an output control end of the first three-axis linkage device, and the auxiliary hole opening device is used for driving a circular pipe to rotate; and according to the hole opening method of the automatic hole opening machine for the large-diameter plastic winding pipe, when hole opening is performed on the circular pipe, while the first three-axis linkage device drives the milling cutter to move, a power mechanism drives all rotating rollers to drive the circularpipe to rotate. The machining efficiency and the machining quality can be improved when the automatic hole opening machine opens holes at different angular positions of the circular pipe, and is suitable for hole opening of circular pipes, such as plastic pipes, steel pipes and the like, especially plastic winding pipes or steel pipes of which the diameters are 200 mm to 5m.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing and relates to automatic opening of round pipes, in particular to an automatic opening machine for large-diameter plastic winding pipes and an opening method thereof. Background technique [0002] At present, when machining the large-diameter plastic winding pipe used on the exhaust gas purification tower, it is necessary to make openings at different angle positions of the plastic winding round pipe for connecting other pipe fittings. In the prior art, manual hand-held milling cutters are often used to open holes at different angles on the round tube. When this method is used, on the one hand, it is often difficult for workers to accurately control the milling cutter, which not only makes the cut uneven, but also reduces the milling holes. On the other hand, the efficiency of workers opening holes is low, which cannot meet the needs of mass production. [0003] In the prior art, th...

AI Technical Summary

Problems solved by technology

However, when manually rotating the plastic winding pipe, it not only consumes labor time, but also has low rotation accuracy, which greatly affects the processing efficiency of the round pipe.

[0005] 2. Poor processing quality

However, when the milling cutter is long, it is easy for the blade to vibrate during the milling process and make the milled hole rougher, thereby reducing the quality of the opening on the round tube and affecting the quality of the processed product.

[0006] 3. Not suitable for cutting pipe sections

In the actual processing process, it is often necessary to cut the entire round pipe into sections according to the production needs. The two methods in the prior art are not suitable for use in the pipe section cutting operation.
