Abstract

The invention discloses a special straightening machine for a stainless steel composite round tube, which is characterized by consisting of a transmission system, a machine body, a base, lead-in rollers, straightening rollers and lead-out rollers, wherein the lead-in rollers, the straightening rollers and the lead-out rollers are correspondingly configured. The transmission system is driven by a 3 KW DC (Direct Current) speed regulation motor, has a rotating speed of 900 to 1,440 revolutions per minute and drives upper rows of drive rolls of the lead-in rollers, the straightening rollers and the lead-out rollers by a transmission shaft, a chain wheel and a chain. The lead-in rollers, the straightening rollers and the lead-out rollers are all characterized by being made of industrial nylon 1010, having basic appearance sizes of outer diameters of phi 200 to phi 220 mm and heights of 80 to 100 mm and being provided with phi 30 center holes and slide stop keyways.

Description

The special straightener of cold-drawing stainless steel bars compound circular tube
Technical field
The present invention relates to cold drawing steel tube straightening technology field, especially relate to the special straightener of a kind of cold-drawing stainless steel bars compound circular tube.
Background technology
Cold-drawing stainless steel bars compound circular tube, is multiple in carbon steel tubing periphery by thin-wall stainless steel outer tube sleeve, is composited through synchronous cold-drawn.Because be subject to powerful cold-pressing deformation effect of stress in process, thereby bending in various degree can occur, aligning is the requisite critical process of cold-drawing stainless steel bars compound circular tube production process.
Disclosed pipe straightener on market, smoothing roll is manufactured by mould steel, and power is large, belongs to universal rubbing, is substantially all the aligning specialized designs of solid drawn tube.The compound pipe of stainless steel, because outer tube wall thickness is thinner, can not stand the strong friction of steel smoothing roll.Because just physical mechanical is compound, easily there is relative motion in thin-wall stainless steel outer tube and inner tube carbon steel tubing in addition under powerful rubbing.
The compound pipe of stainless steel is aligned, and becomes the technical barrier of the compound pipe of stainless steel manufacturing enterprise.At present domestic production producer substantially all adopts the most original artificial aligning or presses and rectify with jack, and not only inefficiency, labour intensity are large, and the rear flexibility of aligning is difficult to be up to state standards.
Summary of the invention
Technical problem to be solved by this invention is to provide the special straightener of the compound pipe of a kind of stainless steel, reduces labor intensity to reach, and increases work efficiency and the free-revving engine of product straightening quality.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
The special straightener of the compound pipe of stainless steel, comprises the compositions such as transmission system, guide-in roller group, smoothing roll group, outlet roller group, drive roll regulating handle.Described transmission system is made up of 3KW DC speed-regulating motor, driving-chain, sprocket wheel and power transmission shaft.Described guide-in roller group, outlet roller group are made up of upper and lower two groups of running rollers respectively, it is characterized in that drawing the compound pipe of stainless steel to be aligned and enter smoothly and derive smoothly.Described smoothing roll by above 3 and below 2 be mutually and stagger and form.Above-listed guide-in roller, smoothing roll, outlet roller are all drive roll, are fixed on power transmission shaft and are driven by motor by chain, sprocket wheel, rotating speed: 900~1440 revs/min.The guide-in roller of following correspondence, smoothing roll, outlet roller are all driven voller, along with the compound pipe of stainless steel is aligned the passive rotation of advancing.Described guide-in roller, outlet roller and smoothing roll are by industrial nylon 1010 manufacture.All running rollers are all processed with that keyway is connected with axle in case rotation relatively.
The present invention has the following advantages: by regulating above-listed all kinds of drive roll position up and down, can align the compound pipe of stainless steel of differently curved degree; By changing the smoothing roll of different size, can meet the compound pipe aligning of different size stainless steel.All running rollers are manufactured by industrial nylon 1010, and not only low, the easy processing of cost, anti-wear performance are good, and have certain elastic modelling quantity, and the outer tube-surface of the compound pipe thin-wall stainless steel of stainless steel is played a very good protection.
Accompanying drawing explanation
Below the mark in this Figure of description 1 expressed content and figure is briefly described:
Accompanying drawing 1 is the special straightener structural representation of the compound pipe of stainless steel of the present invention.
In accompanying drawing 1: 1,2,8,9 is two groups of guide-in rollers, and above-listed 1,2 is drive roll, and following 8,9 is driven voller; 3,4,5,10,11 is smoothing roll, and above-listed 3,4,5 is drive roll, and following 10,11 is driven voller; 6,7,12,13 is two groups of outlet rollers, and above-listed 6,7 is drive roll, and following 12,13 is driven voller; 14 is that transmission system, 15 is that regulating handle, 16 is that body, 17 is the stainless steel compound pipe of plant bottom case, 18 for aligning.
Accompanying drawing 2 is guide-in roller, smoothing roll and outlet roller structural representation.
The specific embodiment
Contrast accompanying drawing below, by the description to optimum embodiment, the specific embodiment of the invention is described in further detail.
As shown in Figure 1, the special straightener of the compound pipe of a kind of stainless steel, is characterized in that being made up of guide-in roller, smoothing roll, the outlet roller of transmission system 14, body 16, base 17 and correspondence system.
According to the compound pipe external diameter of stainless steel to be aligned, all guide-in rollers, outlet roller and the smoothing roll of corresponding specification are installed, regulate above-listed drive roll upper and lower and optimum position, left and right and drafts, the compound pipe 18 of stainless steel to be aligned is imported by 1,2,8,9 liang of group guide-in rollers of guide-in roller, through the rectification of repeatedly bending of 3,4,5,10,11 smoothing rolls, proofread and correct and derive through 6,7,12,13 liang of group outlet rollers again, complete the aligning process of a compound pipe of stainless steel.Because be subject to same drawing deformation effect of stress, the compound pipe of same specification stainless steel, its flexibility is just the same, after first compound pipe aligning of stainless steel is up to standard, be the fixing above-listed all drive rolls of fastening nut positions up and down, until the compound pipe aligning of same specification stainless steel is complete.
More than describing is explanation of the invention, is not limitation of the invention, and limited range of the present invention is referring to claim, and without prejudice to basic structure of the present invention in the situation that, the present invention can do any type of modification.
