Pipe making machine

Abstract

The invention discloses a pipe making machine which comprises an unwinding area, a forming area, a welding area, a polishing area, a straightening area and a cutting area. The unwinding area, the forming area, the welding area, the polishing area, the straightening area and the cutting area are sequentially arranged along a roll material steel plate conveying direction. An unwinding shelf is placed in the unwinding area and is used for placing roll material steel plates; multiple groups of pipe fitting forming mechanisms are placed in the forming area and are used for gradually forming the steel plates into round pipes; and a welding mechanism is placed in the welding area and is used for welding gaps on the round pipes. The pipe making machine has the beneficial effects that (1) by applying the unwinding shelf to the pipe making machine, materials can be conveniently unwinded and winded, so that the material unwinding and winding efficiency is high, and the 'zero' time for replacementcan be realized by adopting double-station unwinding; and (2) by adopting the side wheel seat forming mechanism, a right-and-left threaded screw rod drives two slide block nuts to gather together toward the middle or be separated toward two sides at the same time, so that the position of a forming mould is quickly adjusted; and the positions of the upper ends of two fixed shafts are adjusted andlimited through an adjusting assembly, so that the position stability of the forming mould in production engineering is ensured.

Description

technical field

[0001] The invention relates to the field of pipe making machines, in particular to a pipe making machine. Background technique

[0002] The pipe making machine is mainly divided into two types: one is the common high-frequency welded pipe machine, the other is the stainless steel pipe machine, the high-frequency welded pipe machine is mainly used to produce various iron pipes, water pipes, etc.; and the stainless steel pipe machine The pipe making machine is mainly used to produce various stainless steel decorative pipes, such as: pipes for stair handrails, pipes for anti-theft doors and windows, pipes for stair handrails, guardrails, etc. It can also produce various automobile exhaust pipes and heat exchanger pipes , Fluid pipes, edible pipes, etc. Its processing technology is generally formed by uncoiling, forming, welding, grinding, sizing, straightening, sizing, cutting and other processes. However, the processing quality of the current pipe making mac...
