Abstract

The utility model discloses a clamp device for a tension straightener, relates to a tension straightener for aluminum materials and solves the problems of poor stress situation and inconvenience for replacing a clamp jaw in the conventional structure. The inner part of a clamp body is provided with dovetail grooves which are symmetrical up and down, and the planes of the upper and the lower dovetail grooves are oblique with a certain angle and are provided with sliding plates; an upper slide blocks and a lower slide blocks are respectively arranged in the symmetrical dovetail grooves, a clamp jaw is arranged in each of the upper and the lower slide blocks, and the clamp jaws are connected with the slide blocks by bolts; and the inner part of the clamp body is provided with four hydraulic cylinders, one end of each hydraulic cylinder is fixed on the clamp body through a support, and the other end of the hydraulic cylinder is fixed with the slide through a support. The clamp device for the tension straightener is used in the straightener for aluminum profiles, and has the advantages of being reasonable in stress, and convenient to replace the clamp jaw and the like.

Description

A kind of tension flattening machine gripping mechanism

Technical field

The utility model relates to the straightener of aluminum and its alloy tube, rod section material, particularly a kind of gripping mechanism of tension flattening machine.

Background technology

During tension flattening machine work, fixedly the gripping mechanism of stretching head clamps an end of aluminium, mobile stretching head, move into place according to aluminium length, the gripping mechanism of mobile stretching head clamps the other end of aluminium, and mobile stretching head moves certain displacement under the hydraulic cylinder effect, and aluminium is subject to tension force, certain length that is stretched reaches the purpose of tension straingtening.

The fixedly stretching head of tension flattening machine and mobile stretching head end are gripping mechanism, and the effect of gripping mechanism is that aluminium is clamped, and is unlikely to come off when being subject to certain pulling force; The gripping mechanism jaw can be adjusted simultaneously, satisfies the tension straingtening needs of different cross section shape, different size aluminium.

Traditional tension flattening machine stretching head has inclination certain angle, laterally zygomorphic chute as shown in Figure 7 in the stretching head body, be furnished with up and down two slide blocks in the chute, respectively fills a jaw in the upper sliding block, and jaw and slide block are bolted.When workpiece stretched, because the boosting function on inclined-plane, along with tensile force increases, also more folder was tighter for workpiece.The shortcoming of conventional tension straightener gripping mechanism is that force-bearing situation is bad, and especially the Root Stress at C shape opening is very large, and simultaneously, it is inconvenient to change jaw when stretching different size workpiece.

The utility model content

The purpose of this utility model is exactly for the shortcoming that exists in the prior art, and a kind of tension flattening machine gripping mechanism is provided, and solves the problem that the traditional structure force-bearing situation is bad, change the jaw inconvenience

For achieving the above object, the technical solution of the utility model is as follows:

A kind of tension flattening machine gripping mechanism, comprise caliper, it is characterized in that: described caliper inside is provided with laterally zygomorphic dovetail groove, the plane inclination certain angle of described dovetail groove up and down, and slide plate is housed, upper and lower two slide blocks are set respectively in the laterally zygomorphic dovetail groove, respectively fill a jaw in the upper and lower slide block, jaw and slide block are bolted; Four hydraulic cylinders of the inner installation of described caliper, hydraulic cylinder one end is fixed on the described caliper by bearing, and the other end is fixed by bearing and described slide block.

Described jaw be flat shape by the contact-making surface of sedan-chair section bar.

Described jaw be V-arrangement by the contact-making surface of sedan-chair section bar.

The surface of described jaw is zigzag.

The utility model compared with prior art has the following advantages and beneficial effect:

1, because caliper inside arranges upper and lower slide block and jaw, and by Driven by Hydraulic Cylinder.During work, hydraulic cylinder band movable slider slides, and jaw is closed, clamps the aluminium that needs aligning, and along with the increase of tensile force, aluminium presss from both sides tighter and tighter, reasonable stress.

2, owing to adopt screw fixedly slide block and jaw, jaw is changed convenient, is applicable to the tension straingtening of different cross section shape, different size aluminium.

The specific embodiment

Such as Fig. 1, Fig. 2, Fig. 3 and shown in Figure 5, a kind of tension flattening machine gripping mechanism, caliper 1 is steel-casting, described caliper 1 inside is provided with laterally zygomorphic dovetail groove 1-1, the plane inclination certain angle of described dovetail groove up and down, and slide plate 2 is housed, upper and lower two slide blocks 3 are set respectively in the laterally zygomorphic dovetail groove, respectively fill a jaw 4 in the upper and lower slide block, jaw and slide block are bolted; Four hydraulic cylinders 5 of described caliper 1 inner installation, hydraulic cylinder 5 one ends are fixed on the described caliper 1 by bearing 6, and the other end is fixed by bearing 6 and described slide block 3.

As shown in Figure 2, described jaw 4 be flat shape by the contact-making surface of sedan-chair section bar.If during aligning square-section aluminium 7, only need to replace with, lower plane jaw 4-1.

As shown in Figure 4, described jaw 4 be V-arrangement by the contact-making surface of sedan-chair section bar.If during the aluminium 8 of aligning circular cross-section, only need to change upper and lower V-arrangement jaw 4-2.

As shown in Figure 6, the surface of described jaw 4 is zigzag.Purpose is the frictional force that increases between jaw and the section bar.

During work, the piston rod band movable slider 3 of hydraulic cylinder 5 slides along slide plate 2 in dovetail groove 1-1 inside, and plane jaw 4-1 is closed, the square-section aluminium 7 of needs aligning is clamped, when square-section aluminium 7 is stretched, because the component effect on inclined-plane, along with the increase aluminium of tensile force is also pressed from both sides tighter and tighter.The technical solution of the utility model is disclosed as above by preferred embodiment.

Those skilled in the art should recognize change and the retouching of doing in the situation that does not break away from the scope and spirit of the present utility model that the appended claim of the utility model discloses, all belong within the protection domain of claim of the present utility model.
