Description

Metal part quenching device TECHNICAL FIELD

[0001] The present application relates to the field of quenching equipment, in particular to a metal part quenching device. BACKGROUND

[0002] Quenching is a heat treatment method that changes the internal structure of metal materials by heating them to a certain temperature and then rapidly cooling them to improve their hardness and strength. During quenching, metal materials are first heated to an appropriate temperature and then rapidly transferred to a cooling device for rapid cooling to achieve the desired material properties. This equipment is widely used in mechanical manufacturing, automotive parts, aerospace, and other fields to improve product durability and performance.

[0003] In related technologies, during the quenching process of metal materials, the internal stress of the material changes. When the cooling speed of the material is inconsistent or the cooling positions have a clear sequence, it is very easy to cause the material to deform, and even cause the metal parts to crack, which can seriously affect the forming quality of the material.

[0004] SUMMARY

[0005] The present application provides a metal part quenching device, which aims to maintain a high consistency in the cooling speed of each part of the material during the quenching process, thereby effectively preventing the material from cracking due to inconsistent cooling speed.

[0006] The present application provides a metal part quenching device, which adopts the following technical solution:

[0007] A metal part quenching device, comprising a quenching pool, a quenching device is installed on the left and right sides of the inner wall of the quenching pool, the two quenching devices are slidingly arranged towards each other or away from each other, and a water outlet hole is formed in the quenching device; a support is installed above the quenching pool, a first drive cylinder is installed on the top of the support, the piston rod of the first drive cylinder vertically downward passes through the support, and a metal part is installed at the bottom of the piston rod of the first drive cylinder;

[0008] A water tank and a water pump are installed on the left and right sides of the quenching pool, the water tank and the water pump are connected through a water inlet pipe, and the water pump and the quenching device are communicated through a water outlet pipe;

[0009] A second drive cylinder is additionally provided between the inner wall of the left and right sides of the quenching pool and the two quenching devices, and the two second drive cylinders are used to drive the two quenching devices to move towards each other or away from each other.

[0010] By adopting the technical scheme, when quenching the plate-shaped metal part, the metal part is lowered into the quenching tank by the first driving cylinder, then the two quenchers are slid towards each other until the two quenchers completely cover the metal part. Then the water pump is opened, and the water in the water tank is pumped to the quenchers by the water pump, and the quenchers spray water on the metal part to cool and quench the metal part.

[0011] In this way, the two quenchers cover the metal part, and when the water pump pumps the water in the water tank to the quenchers, the quenchers cool the metal part. Since the two quenchers completely cover the metal part, the water can act on the metal part through the quenchers at the same time, thereby effectively ensuring that the speed of the water sprayed on the metal part by the quenchers is consistent.

[0012] Meanwhile, pumping the water in the water tank by the high-pressure water pump can further increase the flow rate of the water, which makes the water sprayed on the metal part by the quenchers more synchronous, which is more conducive to ensuring the consistency of the speed of the water sprayed on the metal part, thereby preventing the material cooling part from having a clear sequence, and effectively preventing the metal part from cracking due to inconsistent cooling speed, which is conducive to ensuring the forming quality of the metal part.

[0013] Preferably, the water outlet pipe comprises a main pipe and two auxiliary pipes, the quenchers have a "N" shape, and the main pipe is connected between the water pump and the main plate of the quenchers, and the two auxiliary pipes are connected between the water pump and the two side plates of the quenchers.

[0014] By adopting the above technical scheme, the water pump and the quenchers are connected by the main pipe and the two auxiliary pipes. When quenching the metal part, the water pump transmits the water in the water tank to the quenchers through the main pipe and the two auxiliary pipes, which can further ensure the consistency of the speed of the water sprayed on the metal part.

[0015] Preferably, assembly holes are formed in the two side plates of the quenchers.

[0016] By adopting the above technical scheme, the assembly holes are semicircular, and when the two quenchers are spliced together, the assembly holes on the two quenchers form a complete circle. Since the metal part is mounted on the piston rod of the first driving cylinder, the piston rod is often columnar, and when the two quenchers are spliced together to cover the metal part, the two assembly holes can make the two quenchers avoid the piston rod, thereby avoiding the obstruction of the piston rod to the splicing of the two quenchers, and thereby facilitating the tightness of the two quenchers covering the metal part.

[0017] Preferably, the bottom of the quenching tank is provided with a drain hole.

[0018] By adopting the above technical scheme, after the metal parts are water-cooled quenched in the quenching tank, waste water will accumulate in the quenching tank, and the drain hole can timely drain the waste water in the quenching tank to the outside of the quenching tank.

[0019] Preferably, a backwater pipe is installed at the drain hole of the bottom of the quenching tank, one side of the backwater pipe is communicated with the drain hole, the other side of the backwater pipe is communicated with the water tank, and a filter pipe is additionally arranged on the backwater pipe.

[0020] By adopting the above technical scheme, when the metal parts are quenched, the waste water in the quenching tank is drained into the backwater pipe through the drain hole, and then flows back to the water tank through the filter pipe. The backwater pipe and the filter pipe are used to recycle the waste water, thereby saving water resources.

[0021] Preferably, an expansion piece is additionally arranged on the side plate of the quenching device, and the expansion piece is used to adjust the length of the side plate of the quenching device.

[0022] By adopting the above technical scheme, the expansion piece arranged on the quenching device can adjust the length of the side plate of the quenching device, so that the two quenching devices can adapt to metal parts of different specifications and sizes, thereby improving the adaptability of the quenching device.

[0023] Preferably, an insertion slot is arranged at the end of the side plate of the quenching device, one end of the expansion piece connected with the quenching device is integrally formed with an insertion rod, the insertion rod is connected with the corresponding insertion slot through insertion, and an insertion slot is also arranged at the side of the expansion piece away from the quenching device.

[0024] By adopting the above technical scheme, the expansion piece can be further expanded, thereby improving the range of size adjustment of the side plate of the quenching device and making the use more convenient.

[0025] Preferably, the materials of the two quenching devices are high-temperature-resistant materials.

[0026] By adopting the above technical scheme, the quenching device can be prevented from being damaged due to the excessively high temperature of the metal parts.

[0027] In summary, the present application has at least one of the following beneficial technical effects:

[0028] 1. Specifically in quenching plate-shaped metal parts, the metal parts are lowered into the quenching tank by the first drive cylinder, and then the two quenchers are slid towards each other until the metal parts are completely covered by the two quenchers. Then the water pump is opened, and the water in the water tank is pumped into the quenchers by the water pump, and the water is sprayed on the metal parts by the quenchers to cool and quench the metal parts.

[0029] This kind of setting mode, using two quenchers to cover the metal parts, when the water pump extracts the water in the water tank into the quenchers, and the quenchers complete the cooling of the metal parts, since the two quenchers are completely covered by the metal parts, which makes the water act on the metal parts through the quenchers at the same time, and thus can effectively ensure that the speed of water sprayed on the metal parts by the quenchers is consistent;

[0030] At the same time, the water in the water tank is extracted by the high-pressure water pump, which can further speed up the flow rate of the water, which makes the water sprayed on the metal parts by the quenchers have higher synchronicity, which is more conducive to ensuring the consistency of the speed of water sprayed on the metal parts, and thus is conducive to preventing the material cooling parts from having obvious sequence, and thus can effectively prevent the metal parts from cracking due to inconsistent cooling speed, which is conducive to ensuring the forming quality of the metal parts;

[0031] 2. The main pipe and the two pipes are connected to the water pump and the quenchers, when quenching the metal parts, the water in the water tank is transmitted to the quenchers by the main pipe and the two pipes, and the main pipe and the two pipes can further ensure the consistency of the speed of water sprayed on the metal parts;

[0032] 3. The extension piece added to the quenchers can adjust the length of the side plate of the quenchers, so that the two quenchers can adapt to metal parts of different specifications and sizes, which is conducive to improving the adaptability of the quenching device.

[0038] The application will be further described in detail below in combination with the accompanying drawings 1-4.

[0039] Example 1:

[0041] At the same time, referring to FIG. 1, a water tank 6 and a high-pressure water pump 7 are installed on the left and right sides of the quenching pool 1, the water tank 6 and the water pump 7 are connected by a water inlet pipe 8, and the water pump 7 is communicated with the quenching device 2 by a water outlet pipe 9.

[0042] In this embodiment, the quenching device 2 has a whole "N" shape structure, the openings of the two quenching devices 2 are oppositely arranged, and a water outlet hole 3 is formed in the quenching device 2.

[0043] Specifically, when quenching the plate-shaped metal part, the metal part is lowered into the quenching pool 1 by the first drive cylinder 5, then the two quenching devices 2 are slidingly arranged towards each other, until the two quenching devices 2 completely cover the metal part. Then the water pump 7 is turned on, the water in the water tank 6 is pumped into the quenching device 2 by the water pump 7, and the water is sprayed on the metal part by the quenching device 2 to cool and quench the metal part.

[0044] This kind of arrangement, using two quenching devices 2 to cover the metal part, when the water pump 7 pumps the water in the water tank 6 into the quenching device 2, and then the quenching device 2 cools the metal part, since the two quenching devices 2 completely cover the metal part, this makes the water act on the metal part through the quenching device 2 at the same time, and thus can effectively ensure that the speed of the water sprayed on the metal part by the quenching device 2 is consistent;

[0045] Meanwhile, the water in the water tank 6 is extracted by the high-pressure water pump 7, which can further accelerate the flow rate of the water, so that the water sprayed on the metal parts by the quenching device 2 has higher synchronization, which is more conducive to ensuring the consistency of the speed of the water sprayed on the metal parts, thereby preventing the obvious sequence of the material cooling, and effectively preventing the metal parts from cracking due to inconsistent cooling speed, and ensuring the forming quality of the metal parts.

[0046] The embodiment of the application is mainly applied to the quenching of plate-shaped metal parts. In actual production, the specific shape and size of the quenching device 2 can be determined according to the specific workpiece.

[0047] In this embodiment, the materials of the two quenching devices 2 are high-temperature-resistant materials, which are conducive to preventing the quenching device 2 from being damaged due to the high temperature of the metal parts.

[0048] Specifically, referring to FIGS. 1 and 2, the second drive cylinders 10 are arranged between the inner walls of the left and right sides of the quenching pool 1 and the two quenching devices 2. The cylinder bodies of the second drive cylinders 10 are fastened to the inner walls of the quenching pool 1 by fastening bolts, and the piston rods of the second drive cylinders 10 are connected to the quenching devices 2.

The main pipe 11 is connected between the water pump 7 and the main plate of the quenching device 2, and the two auxiliary pipes 12 are connected between the water pump 7 and the two side plates of the quenching device 2. The water pump 7 and the quenching device 2 are connected by the main pipe 11 and the two auxiliary pipes 12.

[0050] Further, referring to FIGS. 1 and 2, assembly holes 13 are formed in the two side plates of the quenching device 2, and the assembly holes 13 are semicircular in shape. When the two quenching devices 2 are spliced together, the assembly holes 13 on the two quenching devices 2 form a complete circle.

[0051] Since the metal parts are installed on the piston rod of the first drive cylinder 5, the piston rod is often columnar, and when the two quenching devices 2 are spliced together to cover the metal parts, the two assembly holes 13 can allow the two quenching devices 2 to avoid the piston rod, thereby avoiding the obstruction of the piston rod to the splicing of the two quenching devices 2, and thereby ensuring the tightness of the covering of the two quenching devices 2 on the metal parts.

[0052] Further, referring to FIG. 1 and FIG. 3, the bottom of the quenching tank 1 is provided with a drain hole 14, after the water-cooling quenching of the metal parts in the quenching tank 1 is completed, the waste water will be accumulated in the quenching tank 1, and the waste water in the quenching tank 1 can be discharged outside the quenching tank 1 in time by using the drain hole 14.

[0054] Specifically, when the quenching of the metal parts is completed, the waste water in the quenching tank 1 is discharged into the backwater pipe 15 through the drain hole 14, and then flows back to the water tank 6 after being filtered by the filter pipe 16, so that the waste water is recycled by using the backwater pipe and the filter pipe 16, thereby being beneficial to saving water resources.

Then the water pump 7 is opened, the water in the water tank 6 is pumped into the quenchers 2 by the water pump 7, and the water is sprayed on the metal parts by the quenchers 2 to cool and quench the metal parts.

[0057] In this way, the metal parts are covered by the two quenchers 2, and when the water in the water tank 6 is pumped into the quenchers 2 by the water pump 7 and then cooled by the quenchers 2, the water can act on the metal parts simultaneously through the quenchers 2 because the two quenchers 2 completely cover the metal parts, thereby effectively ensuring that the speed of the water sprayed on the metal parts by the quenchers 2 is consistent.
