Abstract

The invention belongs to the aluminum sections straightening mechanical field, in particular to a hydraulic stretching machine for straightening alualloy tube, shaping articles and bar materials. The invention is characterized in that: a guide rail supporting slider provided with a drawing head is arranged on a machine foundation which also supports one end of a fixed stretching cylinder; the drawing head comprises a slewing gear and a jaw; a piston rod of the stretching cylinder is connected with the slider; the other end of the stretching cylinder is fixedly connected with one end of a link bearing which is provided with a guide rail support; the guide rail support is connected with a shifting beam which is provided with a traversing crane; both sides of the traversing crane is provided with double bolts which is coincided with a plurality of location holes on the link bearing; the jaw is arranged on the traversing crane. The invention has the advantages of large tension, capacity of improving the mechanical features of aluminum sections and especial adaptation of being used to straighten alualloy tube, shaping articles and bar materials.

Description

Hydraulic stretcher

Technical field:

The invention belongs to the mechanical field of aluminium section bar aligning usefulness, be specifically related to a kind of hydraulic stretcher that aluminium alloy pipe, section bar, bar are used of aligning.

Background technology:

Existing be used for the hydraulic stretcher that aluminium alloy pipe, section bar, bar are used, mostly be the small-sized tension straingtening equipment that on the aluminium section bar production line, uses, its pulling force only is 500T, eliminating stress, improve mechanical performance and mechanical property aspect, do not reach the specification requirement of product, cause that section bar, bar equal strength are low, bending resistance and resistance to torsion be poor.

Summary of the invention:

It is big to the purpose of this invention is to provide a kind of pulling force, can improve aluminium section mechanical performance and mechanical property, the hydraulic stretcher that especially suitable tension straingtening aluminium alloy pipe, section bar, bar are used.

Technical scheme of the present invention: a kind of hydraulic stretcher, form by support, stretching head, travelling car, connection support, moving beam, stretching oil cylinder, it is characterized in that establishing the guide supporting slide on the support, establish stretching head on the slide, go back support fixation stretching oil cylinder one end on the support; Stretching head is made up of whirligig and jaw; The drawing oil cylinder piston rod links to each other with slide; The stretching oil cylinder other end is with to be connected support one end affixed, connects to establish guide supporting on the support and connect moving beam, establishes travelling car on the mobile cross rail; Some locating holes on the travelling car both sides are established double bolt and are connected support match, and establish jaw on the travelling car.

Owing to adopt technique scheme, it is big that the present invention has a pulling force, can improve aluminium section mechanical performance and mechanical property, especially is fit to the advantage that tension straingtening aluminium alloy pipe, section bar, bar are used.

Description of drawings:

Come technical scheme of the present invention is elaborated below in conjunction with the drawings and specific embodiments.Fig. 1 is a structural representation of the present invention.Fig. 2 is the upward view of Fig. 1.

The specific embodiment:

With reference to figure 1, Fig. 2, a kind of hydraulic stretcher is made up of support 1, stretching head, travelling car 3, connection support 4, moving beam 5, stretching oil cylinder 6, establishes guide supporting slide 2 on the support 1, establish stretching head on the slide, go back support fixation stretching oil cylinder 6 one ends on the support 1; Stretching head is made up of whirligig 7 and jaw 8; Stretching oil cylinder 6 piston rods link to each other with slide 2; Stretching oil cylinder 6 other ends are with to be connected support 4 one ends affixed, connect to establish guide supporting on the support 4 and connect moving beam 5, establish travelling car 3 on the mobile cross rail 5; Some locating holes 10 on travelling car 3 both sides are established double bolt 9 and are connected support 4 match, and establish jaw on the travelling car 3 and get final product.
