Abstract

The utility model belongs to the technical field of welding, and particularly relates to a butt welding structure which comprises a first body to be welded and a second body to be welded, wherein the first body to be welded and the second body to be welded are oppositely arranged and welded, a gasket for absorbing welding strain is arranged at the position where the first body to be welded and the second body to be welded are oppositely arranged, and the gasket is sealed between the first body to be welded and the second body to be welded during welding, so that the gasket can be used for buffering the crack of the second part to be welded or the first part to be welded caused by stress release.

Description

Butt welding structure

Technical Field

The utility model belongs to the technical field of welding, and particularly relates to a butt welding structure.

Background

The essential operation in the cutter course of working during welding technique, in order to reduce the processing cost when guaranteeing intensity, often adopt the base member welding of two materials together, for example, adopt the cutter arbor of steel material and the butt welding of tool bit of alloy material, welding technique among the prior art is directly welded both together through the welding usually. This has a high probability of causing cracks in the alloy due to weld stress release during rework after welding.

SUMMERY OF THE UTILITY MODEL

The utility model provides a butt welding structure, which aims to solve the problem that cracks appear in processing after welding in the prior art.

The butt welding structure adopts the following technical scheme:

the butt welding structure comprises a first body to be welded and a second body to be welded, wherein the first body to be welded and the second body to be welded are oppositely arranged and welded, and a gasket for absorbing welding strain is arranged at the position where the first body to be welded and the second body to be welded are oppositely arranged.

As a refinement, the gasket is in the shape of a sheet.

As an improvement, the thickness of the gasket is 0.3-0.8 mm.

As an improvement, the gasket is made of a material with hardness lower than that of the first body to be welded and the second body to be welded.

As an improvement, the first body to be welded is made of steel, and the second body to be welded is made of alloy.

As an improvement, the gasket is made of low-carbon steel.

As an improvement, a groove is formed in the first body to be welded, and a convex block matched with the groove is formed in the second body to be welded.

As a refinement, the groove is U-shaped.

The utility model has the beneficial effects that:

the utility model provides a butt welding structure which comprises a first body to be welded and a second body to be welded, wherein the first body to be welded and the second body to be welded are oppositely arranged and welded, a gasket for absorbing welding strain is arranged at the position where the first body to be welded and the second body to be welded are oppositely arranged, and the gasket is sealed between the first body to be welded and the second body to be welded during welding and can be used for buffering the crack of the second part to be welded or the first part to be welded caused by stress release.

reference numerals:

1: a first body to be welded; 2: a second body to be welded; 3: a gasket; 4: and (4) a groove.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention can be embodied in many different forms than those herein described and it will be apparent to those skilled in the art that similar modifications can be made without departing from the spirit and scope of the utility model and, therefore, the utility model is not to be limited to the embodiments set forth herein.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

An embodiment of a butt welding structure of the present invention is, as shown in fig. 1, a butt welding structure including a first body to be welded 1 and a second body to be welded 2, the first body to be welded 1 and the second body to be welded 2 being arranged opposite to each other and welded, and a gasket 3 for absorbing welding strain being provided at a position where the first body to be welded 1 and the second body to be welded 2 are arranged opposite to each other. Specifically, when welding, seal gasket 3 between first body 1 and the second body of welding of waiting, can be used for buffering that stress release brings that the second waits to weld or the first piece that waits to weld bursts apart, have the characteristics that processing is convenient, with low costs, welding effect is good.

The spacer 3 is in the form of a sheet, specifically, the thickness of the spacer 3 is 0.3 to 0.8mm, in this embodiment, the thickness of the spacer 3 is 0.5mm, and in other embodiments, the thickness of the spacer 3 is 0.3mm or 0.8 mm.

The gasket 3 is made of a material with hardness lower than that of the first body to be welded 1 and the second body to be welded 2. In this embodiment, the first object 1 is made of steel, the second object is made of alloy, and the gasket 3 is made of mild steel.

First body 1 of waiting to weld is equipped with recess 4, and second body 2 of waiting to weld is equipped with the lug with recess 4 looks adaptation, and specifically speaking, recess 4 is the U-shaped, and when the welding, above-mentioned lug and recess 4 set up relatively, are the welding seam place during the welding promptly.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention.
