Titanium pipe straightening machine

Abstract

The invention discloses a titanium pipe straightening machine, belonging to the technical field of metal tubular product polishing machinery. The titanium pipe straightening machine comprises a channel beam, a pair of pipe supporting mechanisms, a hydraulic station, an oil cylinder bracket, an oil cylinder and a pressing die, wherein the channel beam consists of a bottom plate, a first side plate and a second side plate; the first side plate is fixed together with one side of the bottom plate; the second side plate is fixed together with the other side of the bottom plate; a pipe supporting mechanism cavity is formed between the two side plates; a pair of guide rails is fixed in the length direction of the bottom plate; the pipe supporting mechanisms are movably matched with the pair of guide rails; the hydraulic station is arranged on one side of the length direction of the channel beam; the oil cylinder bracket corresponds to the upper side of the transverse channel beam, and is positioned between pipe supporting mechanisms; the oil cylinder is fixed on the oil cylinder bracket, and is connected with a hydraulic pipeline of the hydraulic station; an oil cylinder column of the oil cylinder faces downwards; and the pressing die is fixed at the tail end of the oil cylinder column, and corresponds to the upper side of a pipe supporting cavity. Due to the adoption of the titanium pipe straightening machine, the straightening requirements on titanium pipes with different lengths can be met; operation personnel are prevented from being hurt; adaptability to the change of the diameter of the titanium pipe can be realized; and the stress is uniform, the phenomenon of deformation is avoided, and the service life of an oil cylinder bracket can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of metal pipe straightening machines, in particular to a titanium pipe straightening machine. Background technique [0002] After the large-diameter thin-walled titanium tube is produced and formed, due to the subsequent processes such as rolling and heat treatment, it often produces undesired but inevitable bending deformation. It is currently common to use a straightening machine to straighten However, because the wall thickness of the titanium tube is relatively thin compared to other steel tubes such as stainless steel tubes, if a straightening machine is used to straighten the steel tube, it is easy to cause flattening, crushing, etc., that is, secondary Damage will affect the final yield of titanium tubes. [0003] There is no shortage of technical information about pipe straightening machines in the published Chinese patent documents, such as the authorized announcement number CN2075113U (313 steel ...

AI Technical Summary

Problems solved by technology

[0004] A typical patent such as CN202239084U recommends "a steel pipe straightening machine". The technical point of this patent is to move the motor that easily generates heat outside the machine so that the heat can be directly dissipated to the outside to prevent the equipment from being damaged by overheating and delaying the straightening work ( 0008 column and 0014 column of the manual), especially, this patented scheme has certain reference significance for the straightening of large-diameter thin-walled titanium tubes, but objectively there are the following shortcomings: First, due to the tube support mechanism (the patent is called a support frame) Corresponds to the bottom of the hydraulic cylinder in an immovable manner, so it is picky about the length change of the pipe (the patent is called the workpiece); second, because when the pipe is placed on the support frame, there is no protection on both sides of the length of the pipe Therefore, once it rolls down, it is easy to cause safety hazards that may injure the operator, and accidents in this area are not uncommon in steel pipe manufacturers; Poor adaptability to pipe diameter changes; Fourth, due to the unreasonable structure of the cylinder bracket (the patent is called the main box), that is, the side shape is in the shape of the Chinese character "factory", so there is a risk of deformation during use
