Abstract

The invention relates to a manufacture method of semicircular guide rails for roving circulation of a spinning frame. The manufacture method comprises the following steps that a 2*136mm Q235 cold-rolled steel strip is pulled into a rectangular linear guide rail with the cross section in a shape that the lower part is provided with an opening by a rolling machine, and the distance A of the opening part is 27mm; the linear guide rail formed through stretch bending is sawed into linear guide rail sections with the length being 2500 to 3000mm by a sawing machine, and plastic sheets are filled in rail inner cavities of the linear guide rail sections; a circular profiling mold is leant on middle sections of the linear guide rail sections, and two ends of the linear guide rail sections are pulled by two hydraulic bending arms of a stretch bending machine tool and are inwards pulled at uniform speed by force being 30-50 N, so that the liner guide rail sections are bent into semicircular guide rails with the diameter being 1250 to 1550mm; the connecting end surfaces of the semicircular guide rails formed through stretch bending are sawed into the vertical state by the sawing machine; and holes are drilled on the semicircular guide rails by a drilling mold, in addition, powder is sprayed and coated on the guide rails, and the semicircular guide rails are manufactured. The manufacture method has the advantages that the manufacture process is simple, the processed semicircular guide rails are integrally formed, the precision is high, the quality is good, and the production efficiency is effectively improved.

Description

The manufacture method of half round guide circulating for spinning frame rove

Technical field

The present invention relates to manufacturing technology, be specifically related to a kind of manufacture method of half round guide for the circulation of spinning frame rove.

Background technology

Along with the development of ring spindle yarn machine technology, how to reduce the recruitment of spinning frame, alleviate workman's labour intensity, save management cost, increase economic efficiency and seem very urgent, therefore, the level of spinning frame will directly have influence on the development of textile industry.

In order to improve spinning frame, carry the efficiency of standby rove, tourist bus is normally installed on spinning frame.At present, half round guide on spinning frame is by manually finish line on steel band while processing, steel band is bent to the semicircle of given size, then in semicircular steel band two edges, longitudinally weld the semi-circular strip of steel of given size, in longitudinal semi-circular strip of steel, weld again inside semicircle chimb, make it form rail groove.This processing method is owing to being artificial, and workman's labour intensity is large, and production efficiency is low, and processing is second-rate, and intensity is low, because being adopts the form of welding to make, the rail groove inwall of processing is rough, when the conveying lever of tourist bus moves in rail groove, is easily stuck.

Summary of the invention

Technical problem to be solved by this invention is to overcome above-mentioned deficiency, and a kind of manufacture method of half round guide for the circulation of spinning frame rove is provided, and the method manufacturing process is simple, half round guide monolithic molding of processing, and quality is good, and intensity is high.

Technical scheme of the present invention: the manufacture method of half round guide circulating for spinning frame rove, comprises the following steps:

(1) the Q235 cold-rolled strip of 2 × 136mm is pulled into the rectangle line slideway that cross sectional shape is lower openings by rolling mill, the distance A of opening portion is 27mm;

(2) line slideway in above-mentioned steps (1) is sawn into the line slideway section that length is 2500～3000mm by sawing machine, and with plastic sheet, is filled in the track inner chamber of line slideway section;

(3) circular pattern is leaned against to the interlude of line slideway section, utilize two hydraulic pressure curved booms of stretch bending lathe to hold the two ends of line slideway section, by the strength of 30～50 Ns, at the uniform velocity inwardly draw, make line slideway section bend to half round guide that diameter is 1250～1550mm;

(4) connecting end surface of half round guide of stretch wrap forming is vertical with sawing machine saw;

(5) utilize drill jig to hole on half round guide, and spray powder on guide rail, half described round guide is made.

The present invention compared with prior art has following beneficial effect: manufacturing process of the present invention is simple, half round guide monolithic molding of processing, precision is high, quality is good, the intensity of guide rail is high, the mismachining tolerance of having manufactured while having avoided artificial, reduced workman's labour intensity simultaneously, improved production efficiency, the inner wall smooth of rail groove, half round guide and the line slideway manufactured connect to form annular tourist bus guide rail, can guarantee that the conveying lever of tourist bus moves in rail groove, improve the efficiency of spinning frame conveying rove.

The specific embodiment

The manufacture method of half round guide circulating for spinning frame rove, comprises the following steps:

(1) the Q235 cold-rolled strip of 2 × 136mm is pulled into the rectangle line slideway that cross sectional shape is lower openings by rolling mill, the distance A of opening portion is 27mm, and the width B of rectangular guideway is 50mm, and height C is 36mm, as shown in Figure 2;

(2) line slideway in above-mentioned steps (1) is sawn into the line slideway section that length is 2500～3000mm by sawing machine, and with plastic sheet, is filled in the track inner chamber of line slideway section;

(3) circular pattern is leaned against to the interlude of line slideway section, utilize two hydraulic pressure curved booms of stretch bending lathe to hold the two ends of line slideway sections, by the strength of 50 Ns, at the uniform velocity inwardly draw, make line slideway section bend to half round guide that diameter is 1250mm;

(4) connecting end surface of half round guide of stretch wrap forming is vertical with sawing machine saw;

(5) utilize drill jig to become at half round guide distance guide rail link the hole that 100mm place drill diameter is 7mm, and on guide rail, spray powder, half described round guide is made, as shown in Figure 1.
