Description

Welding anti-deformation tool

Technical Field

The utility model relates to a welding frock particularly, is a welding anti-deformation frock.

Background

In daily welding work, a steel plate needs to be welded along the circumferential unilateral direction of the cylindrical end face of a workpiece (1), and an A face (2) is required to be welded smoothly after welding, as shown in figure 1. When welding is carried out in a free welding state, the A surface (2) after welding is always outward convex at the center due to the action of welding stress, so that the A surface is uneven, as shown in figure 2. In this case, the shape correction must be performed again to flatten the a-side (2) to meet the requirement in fig. 1.

Disclosure of Invention

An object of the utility model is to provide a welding anti-deformation frock can make the work piece A face after the welding level and smooth, has solved the deformation problem after this kind of structure work piece welding in the past.

The utility model discloses a following technical means realize: a welding anti-deformation tool comprises a body, wherein the cross section of the body is circular; the body is provided with a through hole along the diameter extension direction, the through hole is used for penetrating a hook-shaped pull rod, and a hook part of the hook-shaped pull rod is used for hooking and pressing a workpiece; the rod part of the hook-shaped pull rod is provided with a groove for the pressing device to pass through.

The bottom edge of the through hole is flush with the edge of the workpiece 1. So that the hook-type pull rod can just hook the periphery of the workpiece.

Preferably, the groove is a cuboid; when the hook-type pull rod penetrates through the through hole and hooks and presses the workpiece, the groove extends out of the through hole.

Preferably, the pressing device is a wedge.

Preferably, the number of the through holes is equal to that of the hook-type pull rods.

Preferably, an annular sizing block is arranged between the body and the workpiece.

Preferably, the diameter of the body is larger than the diameter of the workpiece.

Preferably, the through holes are uniformly distributed along the circumferential direction of the body.

The utility model discloses with anti-deformation frock through colluding the type pull rod and catching up and treat welding workpiece to utilize closing device to warp the peripheral opposite direction predeformation to the postweld that warp with work piece tip steel sheet, make the welding accomplish the pine after the complete cooling and fall the frock, the A face can resume the temper.

The utility model provides a deformation problem after this kind of structure work piece welding, saved manpower and materials, improved production efficiency, guaranteed the quality of product.

FIG. 5 is a cross-sectional view of the tool body;

fig. 6 is a schematic structural view of the hook-type drawbar.

Wherein, the workpiece comprises 1 part, 2 part A, 3 part, 4 part through hole, 5 part hook type pull rod, 6 part groove, 7 part wedge iron and 8 part annular sizing block.

Detailed Description

The following examples further illustrate embodiments of the present invention. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Example 1:

a welding anti-deformation tool comprises a body 3, as shown in figure 5, the cross section of the body 3 is circular; the body 3 is equipped with through-hole 4 along its diameter extending direction the utility model discloses in, on the same circumference extending direction, through-hole 4 can be a plurality of, and through-hole 4 is used for wearing to establish and colludes type pull rod 5, and consequently, its quantity is the same with the quantity that colludes type pull rod 5.

As shown in fig. 1, when the workpiece 1 is installed, the hook part of the hook-type pull rod 5 is used for hooking and pressing the workpiece 1; the rod part of the hook-shaped pull rod 5 is provided with a groove 6 for the pressing device to pass through.

Specifically, the groove 6 is a cuboid and penetrates up and down; when colluding type pull rod 5 and passing through-hole 4 and colluding and press the 1 circumferential edge of work piece reason, the partly of groove 6 stretches out in through-hole 4 the utility model discloses in, closing device is drift 7, and the diameter of body 3 is greater than the diameter of work piece 1, through-hole 4 along the circumferencial direction evenly distributed of body 3.

The working principle is as follows: during installation, as shown in fig. 4, an annular sizing block 8 is arranged between the body 3 and the workpiece 1, all the hook-shaped pull rods are inserted into corresponding through holes, wedge irons 8 are inserted into grooves of the hook-shaped pull rods 5, the wedge irons 8 abut against the back surface of the body 3, all the wedge irons 8 are uniformly hit by a hammer, the periphery of a steel plate at the end part of the workpiece 1 is forced to be pre-deformed in the opposite direction of deformation after welding by the wedging force of the wedge irons 4, welding is completed, the tool is loosened after complete cooling, and the surface A2 is enabled to be restored to a flat state.

Example 2:

further, the utility model discloses can also set up the through-hole according to the diameter size of work piece 1 on the circumference of different length diameters for it can adapt to the work piece of equidimension not, and the suitability is wider.

The utility model provides a problem that this kind of structure work piece warp after welding, saved manpower and materials, improved production efficiency, guaranteed product quality.

The embodiments of the present invention have been described in detail with reference to the examples, but the present invention is not limited to the described embodiments.
