Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a weld cooling device for frame welding. Background Art

[0002] In the manufacturing process of the frame, welding is a key process step. After welding, the cooling speed and uniformity of the weld directly affect the welding quality, material properties and the overall stability of the frame. Therefore, a weld cooling device for frame welding is required for cooling.

[0003] According to a rapid cooling device for mechanical welding disclosed on the patent website (authorization announcement number: CN116944748A), "The present invention discloses a rapid cooling device for mechanical welding, which belongs to the field of welding equipment. In particular, it relates to a welding auxiliary device that cooperates with a welding machine to cool the weld after welding. It includes: a fixed component, an adsorption device is provided at the bottom of the fixed component to adsorb and fix a guide frame body placed on one side of the weld and deflected on the fixed component; a mobile cooling component suspended on the guide frame body; the guide frame body is provided with two sets of parallel guide rails, and the two sides of the mobile cooling component are correspondingly overlapped and placed on the guide rails to move along the guide rails. The mobile cooling component includes a mobile component corresponding to the guide frame body, and a cooling component for cooling the weld. The cooling component includes a group of air cooling components symmetrically placed on both sides of the weld, and a group of plate cooling components covering the weld. By arranging a frame structure on the upper side of the weld, the weld position completed by the welding gun is quickly cooled while moving along the frame body, thereby improving the cooling efficiency."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model sets a frame structure on the upper side of the weld, and while moving along the frame, quickly cools the weld position completed by the welding gun, controls the spacing between the two sets of magnetic seats, adapts to the two sides of the weld, and adjusts the width. However, in actual use, after the spacing of the magnetic seats changes, it is necessary to add a transverse connecting pipe, which will change the width of the guide frame, while the distance between the guide wheels is fixed. After the magnetic seats are adjusted, the power box needs to be replaced, which is cumbersome and wastes resources. Secondly, the jet air pipe does not stop after rotation. During long-term jetting, the position of the jet air pipe will be offset, colliding with the frame and causing damage. Therefore, it is necessary to improve a weld cooling device for frame welding to solve the above problems. Utility Model Content
