Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metal processing, in particular to a metal quenching device. Background Art
[0002] Metal quenching is to improve hardness and strength. By rapidly cooling, the internal structure of the metal changes to form hard phases such as martensite, thereby enhancing wear resistance and impact resistance.
[0003] For relatively long metal parts, such as metal parts in the shape of rods over 3 meters long, due to their long dimensions, a relatively large quenching pool is required. When quenching, the metal parts need to be moved up and down for picking and placing, and then moved left and right for removing and moving in. The operation directions are at least two, which is rather troublesome. To reduce the operation complexity, in the existing technology, quenching is generally carried out by spraying water. The metal parts are quenched by passing them under the nozzles. In this way, the metal parts only need to be conveyed in one direction. However, this quenching method has a short quenching time and poor quenching effect. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the shortcoming of poor quenching effect of relatively long metal parts in the existing technology, and to propose a metal quenching device.

The quenching device further includes an inner box body and a liquid infusion component. Along the first direction, the inner box body is provided with an inlet slit and an outlet slit for the quenching parts to enter and exit. The inner box body is filled with a quenching solution, and the second liquid level of the quenching solution is higher than at least part of the inlet slit and higher than at least part of the outlet slit. The liquid infusion component can convey the quenching solution into the inner box body, and the liquid infusion speed of the liquid infusion component is greater than or equal to the total liquid discharge speed of the inner box body.
[0007] The quenching device further includes an outer box body located outside the inner box body. The outer box body can hold the quenching solution flowing out of the inner box body. The liquid level in the outer box body is defined as the first liquid level, and the height of the first liquid level is lower than the height of the second liquid level.
[0008] The liquid infusion component includes a circulation pump. The inner box body has a water inlet hole, and the outer box body has a drain hole. The liquid inlet end of the circulation pump is communicated with the drain hole, and the liquid discharge end of the circulation pump is communicated with the water inlet hole.
[0009] The liquid infusion component further includes a cooling device that can cool the quenching liquid. The cooling device is located between the liquid inlet end of the circulation pump and the drain hole.
[0010] The conveyor line includes a conveyor chain, and a number of connectors are installed at the bottom of the conveyor chain, and hanging members capable of fixing quenching parts are installed at the bottom of the connectors.
[0011] The inlet slit portion includes a penetration hole for the quenching part to pass through and a penetration slit communicating with the penetration hole. The connector can enter the inner box through the penetration slit. The discharge slit portion includes a penetration hole for the quenching part to pass through and a discharge slit communicating with the penetration hole.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0017] Refer to Figure 1 - Figure 2 , a metal quenching device includes a suspended conveyor line 8 for suspending and conveying quenching parts in a first direction. The quenching device further includes an inner box 3 and a liquid delivery assembly 18. Along the first direction, the inner box 3 is provided with an inlet slit portion 19 and a discharge slit portion 20 for the quenching parts to enter and exit. The inner box 3 is filled with a quenching solution, and the height of the second liquid level 17 of the quenching solution is higher than at least a part of the inlet slit portion 19 and higher than at least a part of the discharge slit portion 20. The liquid delivery assembly 18 can deliver the quenching solution into the inner box 3, and the liquid delivery speed of the liquid delivery assembly 18 is greater than or equal to the total liquid discharge speed of the inner box 3.
[0018] When the device is working, it continuously drives the quenched parts to move in one direction along the conveyor line 8 by adopting a hanging method. Refer to Figure 1 , the conveyor line 8 drives the quenched parts to enter from the inlet slit 19 of the inner box 3 and discharge from the outlet slit 20. When the quenched parts move inside the inner box 3, since the height of the second liquid level 17 is higher than at least part of the inlet slit 19 and higher than at least part of the outlet slit 20, the quenched parts are always immersed in the quenching solution. During operation, the quenching solution inside the inner box 3 will overflow from the inlet slit 19 and the outlet slit 20. The liquid delivery component 18 of this device can deliver the quenching solution into the inner box 3, and the liquid delivery speed of the liquid delivery component 18 is greater than or equal to the total liquid discharge speed of the inner box 3, ensuring that the height of the second liquid level 17 can immerse the quenched parts.
[0019] With this device, the purpose of immersing long-sized parts in quenching can be achieved, and the quenched parts only need to be conveyed in one direction, reducing the complexity of operation.
[0020] Furthermore, the quenching device further includes an outer box 10. The outer box 10 is located outside the inner box 3. The outer box 10 can hold the quenching solution flowing out of the inner box 3. Define the liquid level in the outer box 10 as the first liquid level 16, and the height of the first liquid level 16 is lower than the height of the second liquid level 17. By using the outer box 10 to hold the quenching solution flowing out of the inner box 3, splashing of the quenching liquid everywhere is avoided.
[0021] Preferably, the liquid delivery component 18 includes a circulation pump 14. The inner box 3 has a water inlet hole 12, and the outer box 10 has a drain hole 13. The liquid inlet end of the circulation pump 14 is communicated with the drain hole 13, and the liquid discharge end of the circulation pump 14 is communicated with the water inlet hole 12. The quenching liquid held in the outer box 10 is re-delivered into the inner box 3 by the circulation pump 14 to achieve dynamic balance.
[0022] Of course, a cooling device 15 can be set as required. The cooling device 15 can cool the quenching liquid. The cooling device 15 is located between the liquid inlet end of the circulation pump 14 and the drain hole 13. The quenching liquid is cooled by the cooling device 15. The cooling device 15 can adopt the method of pipeline plus air cooling in the existing technology.
[0023] As a conveying method, the conveyor line 8 includes a conveyor chain. A number of connectors 7, such as iron chains, are installed at the bottom of the conveyor chain. A hanging member 9 capable of fixing the quenched parts, such as a sling, is installed at the bottom of the connector 7. The rod-shaped quenched parts are suspended by two slings.
[0024] Refer to Figure 1, the inlet seam part 19 includes a penetration hole 6 for the quenching part to pass through and a penetration seam 5 communicating with the penetration hole 6. The connecting member 7 can enter the inner box body 3 through the penetration seam 5. The discharge seam part 20 includes a discharge hole 2 for the quenching part to pass through and a discharge seam 1 communicating with the discharge hole 2. The connecting member 7 can move to the outside of the inner box body 3 through the discharge seam 1. The height of the second liquid level 17 is higher than the highest points of the discharge hole 2 and the penetration hole 6.
[0025] The discharge seam 1 and the penetration seam 5 are provided for the connecting member 7 to pass through the inner box body 3. The larger-sized discharge hole 2 and penetration hole 6 are provided for the quenching part to pass through. The liquid inside the inner box body 3 is continuously supplied upward by the circulation pump 14 while continuously discharged from the discharge seam 1, the discharge hole 2, the penetration seam 5, and the penetration hole 6, so that the height of the second liquid level 17 is higher than the highest points of the discharge hole 2 and the penetration hole 6, ensuring that the quenching part can be immersed in the quenching liquid.
[0026] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, any technical solution, concept, and design obtained by equivalent replacement or change should be covered within the protection scope of the present invention.
