Description

Technical Field

[0001] The utility model relates to the technical field of copper tube processing, in particular to a copper tube pushing device for a necking machine. Background Art

[0002] Copper tubes are generally used in evaporators as connectors to connect internal components of the evaporator, or to absorb and release heat through the copper tubes during use, so that the evaporator can be used normally and its performance is intact. Different copper tubes need to be connected during use to ensure the diversity of their uses. Since copper tubes are not easy to connect, some copper tubes need to be shrunken before connection to facilitate the connection and installation of the copper tubes.

[0003] After searching, it was found that the publication number is CN214601521U, and the name is a shrinking machine for copper tube processing with high stability. The application puts forward the problem that the existing shrinking machine for copper tube processing needs manual loading during use. The operator's momentary negligence during use may cause damage to the raw materials and bring danger. Feeding the clamping column directly through the feeding box increases the convenience and safety during use. The groove plate installed inside the feeding box can place the pipe to be shrunken, which is convenient for the output of the pipe, and a return spring is installed under the groove plate. The elastic force of the return spring will lift the pipe placed inside the groove plate so that the pipe can be smoothly output. Since a feeding trough is provided at the top of the feeding box, and a drawer plate is embedded in the feeding trough, when feeding is required When feeding, the draw plate is pulled to make the pipe pop out to the top, and through the joint action of the positioning column and the discharge column, the pipe is made to enter the inside of the clamping column to fix the pipe, and after the pipe is used up, the material changing door is opened, and the handle installed on the groove plate is pulled to add raw materials to the inside of the groove plate. However, this application needs to manually pull the draw plate when feeding and pushing, which is more troublesome. At the same time, the positioning of the return spring is not delicate and reliable enough, and the positioning is not accurate enough. The feeding trough can arrange multiple copper tubes side by side, and several copper tubes are taken out in time, which has a relatively large impact on the downward pressure of the return spring. The return spring is very easy to stretch at this moment, causing the feeding trough to move upward, affecting the positioning and discharge of materials, and affecting the pushing and fixing. Further improvements can be made. At the same time, the wear caused by the sliding of the copper tube is large, which can also be further improved.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
