Abstract

The invention relates to a production method of a cloth stringing pipe. The production method comprises the following steps: (1) a straight-line pipe is welded; (2) prepressing: a first pressure head is used for pressing a welding line of the straight-line welded pipe; (3) rough pressing: a second pressure head is used for applying a force effect to the welding line of the straight-line welded pipe, so that the straight-line welded pipe is deformed until a shoulder part is formed; the shoulder part is heated; and the second pressure head is continuously used for pressing the straight-line welded pipe; (4) finish pressing: a movable frame groove is used for supporting the straight-line welded pipe; a third pressure head is used for applying a force effect on the welding line of the straight-line welded pipe; and meanwhile, two edge frames of the movable frame groove oppositely move to press an inner ring; and (5) finishing: the rectangular frame groove is used for supporting the straight-line welded pipe; and a flat pressure head is used for applying a force effect to the straight-line welded pipe, so that the straight-line welded pipe is deformed, and the pressing molding is performed. The production method can produce a steel material to the cloth stringing pipe, so that the molding rate is high; and as the outer ring of the produced cloth stringing pipe is square, the structure is more stable in use.

Description

A kind of manufacture method of Cloth crossing tube

Technical field

The present invention relates to a kind of processing method of metal, particularly relate to a kind of manufacture method of Cloth crossing tube.

Background technology

Cloth crossing tube is generally positioned at a tool both sides, and for providing support seat surface cloth and fix, it extends at length direction, also can be used as a bracing frame for tool entirety.If application number is the Chinese utility model patent of 201320648932.8, disclose a kind of bed of lying of Cloth crossing tube structure, it comprises bed surface pipe, flexible bed surface, rear foot tube, seat stay pipe, front foot pipe and leg rest stay tube, two bed surface pipes be arranged in parallel are set to sigmoid curve, flexible bed surface is fixed on bed surface pipe, forms S shape curved surface; Rear foot tube and front foot pipe are fixed on bed surface pipe, and seat stay pipe and leg rest stay tube are articulated on bed surface pipe; By arranging tongue-and-groove on bed surface pipe, be fixed in tongue-and-groove by flexible bed surface, and rear foot tube and front foot pipe be fixed on bed surface pipe, make bed surface pipe provide comfortable support angle to lie for people and lean on, simplify complicated structure, make weight saving, manufacturing cost reduces.

Cloth crossing tube also can be used for setting up of sunshade, as application number a kind of grape shed disclosed in 2009201924514, it comprise column, with its ceiling connecting rod be fixedly connected with, the top cloth that is flexibly connected with ceiling connecting rod by Cloth crossing tube, described ceiling connecting rod besieged city is square, its lower surface activity arranges one group of Cloth crossing tube, and top cloth is connected on described Cloth crossing tube.This utility model adopts Cloth crossing tube to remove erection top cloth, thus makes to push up the function that cloth has easy folding and unfolding, thus is regulated illumination according to weather by the top cloth of easy folding and unfolding, is suitable for the growth of grape.

Right Cloth crossing tube method for making is complicated, and usually adopt aluminum alloy material to process, this also makes the on the high side of Cloth crossing tube.As adopted steel to process, though can reduce costs and promote intensity, propose new requirement to machine-shaping, prior art obviously cannot meet this requirement.

Summary of the invention

The present invention will solve the problems of the technologies described above, thus provides a kind of manufacture method of Cloth crossing tube.

The technical scheme that the present invention solves the problem is as follows:

A manufacture method for Cloth crossing tube, comprises the following steps:

1. welding straight beam pipe: with plane steel for raw material, be rolled into tubulose with rolling machine, and carry out weld seam with welding machine, make ERW;

2. precompressed: carry out support to described ERW with ladder-shaped frame groove, applies the effect of power, makes described ERW generation deformation to described ERW with the first pressure head; In pre-compaction process, described first pressure head is suppressed facing to the weld seam of described ERW;

3. slightly press: with rectangle frame groove, support is carried out to described ERW, with the effect of the second pressure head facing to the weld seam applying power of described ERW, make described ERW generation deformation until form shoulder, to described shoulder heating, the hardness at heating position is made to be starkly lower than non-heated position, continue to suppress ERW with described second pressure head, suppress formed shoulder;

4. pressure-sizing: adopt activity box groove to carry out support to described ERW, with the effect of the 3rd pressure head facing to the weld seam applying power of described ERW, two frames of activity box groove move in opposite directions simultaneously, suppress inner ring;

5. repair: with rectangle frame groove, support is carried out to described ERW, adopt concora crush head to apply the effect of power to described ERW, make described ERW generation deformation, compressing;

Described second pressure head front end is expanded; The protuberance that described concora crush head comprises body and inner ring avalanche can be prevented closed.

Preferred as technique scheme, step 3. in, during to described shoulder heating, adopt flame gun.

Preferred as technique scheme, step 5. in, in dressing process, the power that described concora crush head applies is even to be strengthened post, until the shaping rear stopping intensified pressure of described ERW, carries out pressurize process with maximum pressure.

Preferred as technique scheme, the pressurize processing time maintains 10 ~ 30S.

Preferred as technique scheme, before finishing, also heats two bottom comer of described ERW, makes the hardness at heating position be starkly lower than non-heated position.

The present invention has following beneficial effect:

1, in pressing step of the present invention, adopt ladder-shaped frame groove to carry out support, make the Lower Half of ERW can bear larger power, when making first half generation deformation, Lower Half can also virtual standstill;

2, the present invention slightly presses in step, and the compacting through the second pressure head produces shoulder, then to after shoulder heating, continues, with the second pressure head compacting, to make shoulder that obvious deformation occur, make shoulder become sharp-pointed, for the shaping of next portion lays the foundation;

3, in coining step of the present invention, adopt activity box groove to carry out support, the 3rd pressure head applies the effect of power simultaneously, makes Cloth crossing tube can basic forming;

4, in pre-shaping step of the present invention, the 3rd pressure head adopted has body and protuberance, and body is responsible for exerting pressure, and Cloth crossing tube is repaired and is shaped, and protuberance can prevent inner ring from closing also can prevent inner ring avalanche, has remarkable effect;

5, steel can be made Cloth crossing tube by present invention process, and not only ratio of briquetting is high, and the Cloth crossing tube made due to outer ring be square, therefore use time structure more firm.
