Description

Technical Field

[0001] The utility model relates to the technical field of resistance welding machines, in particular to a resistance welding machine with a cooling function. Background Art

[0002] Resistance welding equipment is a device that connects two metal materials together through high temperature and high pressure. Its working principle is to generate heat at the joint through electric current, so that the temperature of the joint increases and the two materials fuse together. Resistance welding equipment must maintain a certain temperature during use to ensure that the current flowing through the joint can generate enough heat. In order to ensure the stability and safety of resistance welding equipment during operation, the temperature of the equipment needs to be reduced in time. Therefore, resistance welding equipment usually needs to use cooling methods to reduce the temperature of the equipment, and common cooling methods include air cooling, water cooling, etc.

[0003] Existing equipment, such as the patent with publication number "CN 217571267 U", discloses a resistance welding machine with cooling function. Through the cooperation of a water storage tank, a first cooling box, a second cooling box, a lower welding head, a second heating device, a circulation pipe, a baffle and a semiconductor refrigeration plate, it is convenient to cool the upper welding head and the lower welding head through the water inside the semiconductor refrigeration plate, and the water after cooling is recycled to avoid waste of resources. During the operation of the resistance welding machine, the upper and lower welding heads will maintain a high temperature, and the lower welding head will maintain a high temperature, which may cause the welding material to burn or oxidize, affecting the welding quality. At this time, the lower welding head needs to be cooled. In the cooling process of the above patent, only the bottom of the lower welding head can be partially cooled during the cooling process of the lower welding head. However, during the welding work, the bottom end of the upper welding head is usually in contact with the top of the lower welding head to generate a large amount of heat. Only cooling the bottom end of the lower welding head cannot take away the heat from the top of the lower welding head in time. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a resistance welding machine with a cooling function, comprising a machine body, a welding head and a welding table, the welding head is connected to the bottom of the welding rod, the welding rod is connected to the top level of the machine body through a connecting rod, the welding table is connected to the middle level of the machine body through a fixing rod, the welding table is located directly below the welding head, the bottom end of the machine body is connected to a workbench, the workbench is connected to a water collecting trough, the water collecting trough is located directly below the welding table, the inner bottom of the machine body is connected to a water storage tank, the water collecting trough and the water storage tank are connected through a connecting pipe, the water storage tank is connected to a water pump, the water pump is connected to a water pipe, the other end of the water pipe is connected to the welding table, empty grooves are arranged around the inner and outer edges of the welding table, a cavity is arranged at the inner bottom of the welding table, the empty grooves are connected to the cavity, the water pipe is connected to the empty groove, the cavity is also connected to a water pipe, and the water pipe is located in the water collecting trough.

[0006] The working principle of the utility model is as follows: during welding work, the water pump operates to transport the cooling water in the water tank to the welding table through the water pipe, the cooling water is poured into the empty slots and cavities in the welding table, and the water pipes connected to the cavities fall into the water collecting tank, and the cooling water returns to the water tank through the connecting pipe to enter the next cycle.

[0008] Furthermore, the space formed by the slot and the cavity is a cooling chamber, and a spiral water channel is provided in the cooling chamber, spiraling downward around the central axis of the welding table, and the top and bottom of the spiral water channel are both connected to the water pipe. Through the arrangement of the spiral water channel, the cooling water can flow down from the top to take away the heat when flowing through the cooling chamber, avoiding the mixing of the cooling water in the cooling chamber with the cooling water in the cooling chamber when entering the cooling chamber, and thus failing to achieve the best cooling effect.

[0009] Furthermore, a contactor is provided in the welding table, and the contactor is electrically connected to the welding table. Through the arrangement of the contactor, the welding table can be heated evenly, and the influence of excessive local temperature on welding work can be avoided.

[0011] Furthermore, the outer top of the machine body is connected with a serpentine tube, and the serpentine tube is connected with a light bulb. Through the arrangement of the light bulb, when processing smaller products, light can be focused on the welding table, and the welding points can be welded more clearly.

[0012] Furthermore, there are multiple welding heads, and the welding heads are detachably connected to the welding rod. Through the provision of multiple welding heads, a suitable welding head can be selected according to the product to be processed during work. BRIEF DESCRIPTION OF THE DRAWINGS
