Description

A kind of light high-strength composite pipe and manufacture method thereof

Technical field

The present invention relates to a kind of light high-strength composite pipe and manufacture method thereof, be mainly used in the roller of textile dyeing machinery, leather machine, papermaking equipment.

Background technique

The method of domestic production composite cloth guider body mainly is that employing is made with the structure of " manufacture method of composite cloth guider " of Huangshi Spinning and Weaving Machinery Plant's patent No. 85100913.1 (inventor Du Long merit) at present.Product specification is Ф 100, Ф 125, Ф 150, Ф 180, Ф 200mm, the structure of roll body, and the outer 2-1.5mm corrosion resistant plate that adopts, internal layer adopts the 2-2.5mm Carbon Steel Plate, and rumble is composited in rolling.Its manufacture method is as follows: the roll body skin: 1. blanking, 2. use semicircle concavo-convex mold pressing circle, and 3. clamp the weldering of roll body waypoint, 4. roll extrusion smooth welded seam, 5. full seam welding, 6. roll extrusion weld seam once more, 7. 8. weld seam polishing is fixed on roll body rumble circle in the high-precision mould.Roll body internal layer: be similar to the outer field method of roll body and will press roll body that circle is shaped only behind spot welding, roll extrusion weld seam, roll body in this is pressed into carries out compoundly in the outer roll body,, the roll body material is extended reach rounding and compound tight again through interior rumble.

This method is referred to as presses rumble forming method in the circle, its shortcoming: along with barrel length increases, the increase of diameter constantly increases the weight of roll body, raw material have not only been wasted, the more important thing is because the increase of roll body deadweight, under cloth tension force and friction factor condition of limited, difficult with this roll body normal rotation, and entire machine is moved under heavy load all the time.

Summary of the invention

The purpose of this invention is to provide a kind of light high-strength composite pipe and manufacture method thereof, have higher intensity, conservation alleviates the roll body deadweight simultaneously.

A kind of light high-strength composite pipe is composited by the Clad Steel pipe crimping, outer for approaching corrosion resistant plate pipe crimping formation, internal layer is made of thin Carbon Steel Plate pipe crimping, and according to roll body diameter and length, the thin carbon steel pipe crimping of internal layer is manufactured with the stiffening rib pipe of several concavo-convex alternate shaped.

For increasing the roundness of radial strength and body, have additional several support hoops in the thin carbon steel tubing.

Wherein the cross section semicircular in shape of tongue and groove also can take the shape of the letter U, triangle, trapezoidal etc.

A kind of manufacture method of light high-strength composite pipe is as follows:

1, by the size blanking, 2, sheet material after the blanking is become the sheet material with several concavo-convex alternate shaped with the Mold Making with several concavo-convex alternate shaped, and leave the usefulness 3 of the trimming that stretches together under the surplus, cut edge 4 according to development size, be rolled into cylinder with mould, 5, clamp roll body spot welding, welding 6, with roller in this under tension, carry out shaping 7 with concavo-convex mould, under tension, pair roller body and function mould carries out cold hobbing, reach with outer roll body and carry out the required fit dimension requirement of compound tense, roll body 8 in forming, fixing outer roll body, 9, carry out interior roll body with concaveconvex shape and outer roll body compound; 10, it is cold drawn to have the roll body internal layer of concaveconvex shape to carry out with mould, makes the interior roll body plastic deformation with concaveconvex shape, compound tightr, obtains light high-strength composite pipe, reaches the quality standard that Ministry of Textile Industry works out fabric guide roll.

Because adopt said structure and manufacture method, this composite pipe has higher intensity, the while conservation, roll body can improve the roll body resistance to flexure from heavy and light, and is compound tightr.

Embodiment

Mode of execution 1

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of light high-strength composite pipe is composited by the Clad Steel pipe crimping, outer for approaching corrosion resistant plate pipe crimping 1 formation, internal layer is made of thin Carbon Steel Plate pipe crimping 2, according to roll body diameter and length, the thin carbon steel pipe crimping of internal layer is manufactured with the stiffening rib pipe of several concavo-convex 21 alternate shaped.

For increasing the roundness of radial strength and body, have additional several support hoops 22 in the thin carbon steel tubing.

The cross section semicircular in shape of wherein concavo-convex 21 grooves also can take the shape of the letter U, triangle, trapezoidal etc.

1, by the size blanking, 2, sheet material after the blanking is become the sheet material with several concavo-convex alternate shaped with the Mold Making with several concavo-convex alternate shaped, and leave the usefulness 3 of the trimming that stretches together under the surplus, cut edge 4 according to development size, be rolled into cylinder with mould, 5, clamp roll body spot welding, welding 6, with roll body in this under tension, carry out shaping 7 with concavo-convex mould, under tension, pair roller body and function mould carries out cold hobbing, reach with outer roll body and carry out the required fit dimension requirement of compound tense, roll body 8 in forming, fixing outer roll body, 9, carry out interior roll body with concaveconvex shape and outer roll body compound; 10, it is cold drawn to have the roll body internal layer of concaveconvex shape to carry out with mould, makes the interior roll body plastic deformation with concaveconvex shape, compound tightr, obtains light high-strength composite pipe, reaches the quality standard that Ministry of Textile Industry works out fabric guide roll.

The solution of the present invention is that the outer corrosion resistant plate that approaches that adopts of roll body is made, the roll body internal layer adopts thin Carbon Steel Plate, according to diameter and length, be made into several concavo-convex 21 shape stiffening ribs, roll into tube with mould, with interior roll body 2 under tension, stretch shaping with concavo-convex die drawing, then to roll body 2 under tension, carry out cold hobbing with specific mould, make to cause to reach and carry out the required fit dimension requirement of compound tense, and utilize the internal layer concave-convex shape to have certain elastic reaction, carry out compound with outer roll body 1 in radial direction with outer roll body, and have preferably and combine closely, and utilize the elasticity of concave-convex shape stiffening rib, and remake plastic deformation, make roll body compound tightr reliable.Solved in the prior art, the fabric guide roll body generally all adopts corrosion resistant plate and carbon element plate 2+2 or 1.5+2.5 to carry out compound, the problem of roll body Heavy Weight, according to diameter and length, can be with internal layer with approaching Carbon Steel Plate, be made into several concave-convex shape stiffening ribs, promptly improved the resistance to flexure of roll body, alleviated the weight of roll body again, roll body is easily turned round, for complete machine has alleviated the action load, mainly be applicable to the manufacturing of the roll body series products in textile dyeing machinery, papermaking equipment and the imitation leather machinery.
