Description

A school type device for welding frame

Technical Field

The utility model mainly relates to the automatic weld equipment field, concretely relates to school type device for welding frame.

Background

There is a need in the art for welding large frame members that are formed from multiple pieces of material. Because the heat and internal force generated during welding change, the formed product has large deformation, so that the detection and correction calibration needs to be performed after the welding is finished. The traditional correction type is a mode of heating by flame, so that a weldment is rapidly cooled after being locally heated to generate the change of internal stress, the mode is relatively dependent on the requirement of manual operation skills, the universality is not realized, and the following technical problems are solved:

firstly, the model calibration work efficiency is low. Because the welding points of a plurality of tools such as a flame gun, a sizing tool and the like need to be held manually, the welding points are heated and sized and then cooled by adopting the water cooling and other modes, and the welding points of a large frame piece lead to more points which possibly need sizing, so that the sizing working efficiency is extremely low, and the follow-up operation is seriously influenced.

Secondly, the calibration has no uniformity and poor accuracy. Because most of the existing calibration methods are that a workpiece is locally heated and then cooled by water, so that the workpiece is locally subjected to stress change and is deformed, the method depends on the operation skill and experience of workers, the operation skill and experience of manual calibration at each time are not unified, calibration results among frame piece products in different batches or among different welding points of the same frame piece product are not unified, the calibration accuracy is poor, and the quality and the strength of the product are finally influenced.

Thirdly, the labor intensity of the model calibration is high, and a certain point of the model calibration is easy to forget. Due to manual correction, the labor intensity of personnel is high; moreover, as a large frame member has more welding points, the conditions that a certain welding point forgets to correct the shape and skips the shape correction often occur, and the quality and the strength of the product are seriously influenced.

Fourthly, the automation and the intelligence degree are low. The existing calibration operation is not only manual operation, but also manual feeding before calibration and manual blanking after calibration, so that the calibration cannot be used with other automatic equipment (for example, automatic feeding and blanking transmission equipment cannot be connected, and automatic detection equipment cannot be connected before calibration), the calibration cannot meet the operation requirements of high efficiency and automation, and automatic system operation cannot be formed.

Fifthly, the risk of correction is high. Because the butt welding points of a plurality of tools such as a flame gun, a sizing tool and the like need to be held by manpower to heat and size one by one, and then cooling is carried out by adopting the water cooling and other modes, dangerous components such as high temperature, flame, cooling water vapor and the like exist in an operation field, the misoperation danger of staff is easy to occur, and potential safety hazards exist in the field.
