Description

Technical Field

[0001] The invention relates to the technical field of die casting quenching devices, and more specifically to large-scale integrated casting automatic quenching transfer equipment. Background Art

[0002] Pressure casting is referred to as die casting. It is to inject molten liquid metal into the injection chamber of the die casting machine. Through the movement of the injection punch, the liquid metal passes through the mold pouring system at high speed under high pressure, crystallizes under pressure, and quickly cools and solidifies to form a die casting. The introduction of the die casting production process not only greatly improves the production efficiency of the connecting rod, but also the connecting rod produced by die casting has a higher assembly accuracy. However, aluminum products obtained by casting also have certain defects, such as large stress inside and loose structure, so that its strength and density are difficult to meet the requirements. Therefore, a series of heat treatments are required, such as solid solution, quenching, aging treatment, etc. Quenching is divided into many types according to the medium;

[0003] The quenching treatment using cooling water as the medium is also called water quenching treatment. For some large integrated castings, because the castings are large in size and heavy in weight, some use hoisting to transfer the castings to the quenching pool for quenching. However, the temperature of the castings will drop during the hoisting process, and the ideal quenching treatment cannot be achieved. In addition, during the hoisting process of the castings, the hoisting connection is also more troublesome because the temperature of the castings is relatively high. As a result, the quenching treatment of the castings is more troublesome as a whole and the production efficiency is low. Summary of the invention

[0042] Working principle: The present invention is an automatic quenching transfer equipment, which is suitable for large integrated castings, such as Figure 1 Therefore, the quenching assembly 20 can be moved to the heating device by hoisting, and can be moved to the drainage to drain and change the water;

[0043] After being heated, the casting body 31 on the casting positioning assembly 30 is transferred by a robot and placed on the positioning fixture table 32, and connected to the quenching table 12 of the transfer mechanism 10 by bolts 33;

[0044] Then the transfer mechanism 10 enables the quenching workbench 12 to descend into the water tank 21 of the quenching assembly 20, and the casting body 31 is immersed in the cooling water of the water tank 21; after ensuring that the casting body 31 is completely immersed in the water and quenched for 5 seconds, the transfer mechanism 10 drives the casting body 31 to float up, and then the robot takes the casting;

[0045] In use, the casting pressing assembly 14 can be used to replace the bolt connection. The pressing rod 141 on the casting pressing assembly 14 can be rotated under the drive of the pressing motor 14. When the casting body 31 needs to be positioned, the pressing rod 141 is turned down to press on the casting body 31. When the casting body 31 needs to be taken out of the water tank 21, the pressing rod 141 can be rotated upward to separate from the casting body 31.

[0046] After continuous quenching, the temperature in the water tank 21 will rise, which is monitored by the thermometer 23, and the water inlet pipe 25 and the water outlet pipe 26 are opened to inject cooling water into the water tank 21 to reduce the temperature;

[0047] Moreover, the slag bag waste generated after batch quenching production falls into the water tank 21 and is collected in the slag bag collecting frame 24. The slag bag waste can be dumped by hoisting, avoiding the slag bag waste being placed in the water tank 21 for a long time, causing the cooling water to deteriorate and thus having an adverse effect on the casting.

[0048] The embodiments are used to illustrate the present invention, but not to limit the present invention. Any person skilled in the art may modify the embodiments without violating the spirit and scope of the present invention, and therefore, the scope of protection of the present invention shall be as set forth in the claims of the present invention.
