Description

Technical Field

[0001] The utility model relates to the technical field of tin processing, in particular to a precision molding device for tin materials. Background Art

[0002] Tin soldering rods are welding rods used for soldering. Tin soldering can be used for sealed metal welding without requiring high temperature and high pressure. According to the different critical points of liquidus temperature, solder bars are divided into high-temperature solder bars and low-temperature solder bars. Among them, the solder bars with liquidus temperature higher than the eutectic melting point of tin-lead at 183 degrees are high-temperature solder bars. High-temperature solder bars are formed when a high proportion of silver, antimony or lead is added to the solder alloy. High-temperature solder bars are mainly used for component assembly that does not change during motherboard assembly. Existing solder bars need to be cast during production.

[0004] Although the above patent can adjust the distance between the sealing piston plate and the pouring port according to the scale, and thus can process tin bars of different lengths according to production needs, it has the following disadvantages. When in use, after the tin pouring is completed, it takes a long time to cool before the tin bar can be taken out. Natural cooling will cause uneven temperature distribution of the tin during the solidification process, resulting in excessive cooling of some areas and stress concentration, thereby causing thermal cracks and shape deformation, affecting the quality of the tin bar, and further improvement is needed. For this reason, we propose a precision molding device for tin materials. Utility Model Content

[0013] Preferably, the output end of the motor movably passes through the left inner wall of the bracket and is fixedly connected to the left end of the rotating plate.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The cooling efficiency can be improved by arranging water pipes, electric valve pipes and cooling grooves to cooperate with each other. When in use, cold water is transported to different electric valve pipes through water pipes, and then transported to different cooling grooves to cool the tin bars in the forming grooves, so that the tin bars are cooled quickly, and the temperature distribution of the tin bars is uniform during the solidification process, so as to avoid stress concentration caused by excessive cooling in some areas, reduce the occurrence of thermal cracks and shape deformation, ensure the quality of the tin bars, and make the tin bars precisely formed. By arranging multiple cooling grooves, the tin bars in different forming grooves can be cooled separately and simultaneously, so that the tin bars can be cooled at the same time, thereby improving production efficiency, and ensuring that the tin bars in each forming groove reach the required cooling temperature, thereby improving product quality;

[0016] 2. The guide plate can delay the time of cooling water in the cooling tank, so that the cooling water flows in a curved manner in the cooling tank, effectively delaying the flow rate of the cooling water, and prolonging the time it stays in the cooling tank, thereby increasing the contact time with the forming tank and improving the cooling efficiency. At the same time, it can reduce the use of cooling water, save water resources, and reduce production costs;

[0017] 3. By setting up a water tank and a conveyor to work together, the material can be automatically received. When in use, pour water into the water tank, and the demoulded tin bar falls into the water tank and falls on the conveyor belt of the conveyor. The resistance of the water can effectively slow down the falling speed of the tin bar, thereby reducing the impact force generated when the tin bar hits the ground, which helps to protect the surface of the tin bar from damage, and then it is transported to the designated location through the conveyor.
