Description

Technical Field

[0001] The utility model relates to the technical field of valve processing, in particular to a novel quenching device. Background Art

[0002] The function of the valve is to input air into the engine and discharge the exhaust gas after combustion; from the engine structure, it is divided into intake valve and exhaust valve; the function of the intake valve is to suck air into the engine and mix it with fuel for combustion; the function of the exhaust valve is to discharge the exhaust gas after combustion and dissipate the heat; the valve is composed of a valve head and a stem; the temperature of the valve head is very high (intake valve 570~670K, exhaust valve 1050~1200K), and it also bears the pressure of the gas, the force of the valve spring and the inertia force of the transmission component, and its lubrication and cooling conditions are poor, requiring the valve to have certain strength, rigidity, heat resistance and wear resistance.

[0003] At present, when quenching the valve stem, the valve stem is usually directly placed in a quenching pool for quenching and cooling after the valve stem is heated. After the valve stem performs free fall, the valve stem and the quenching pool will collide, which may easily cause the valve stem to deform and be damaged, so improvement is needed. Utility Model Content

[0004] The utility model aims to provide a novel quenching device to solve the problem in the background art that the valve stem is prone to collide with the inner wall of the quenching pool and thus deform.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a novel quenching device, comprising a quenching pool, wherein a plurality of buffer components are arranged inside the quenching pool;

[0006] The buffer assembly comprises an air disk fixed inside the quenching pool, one end of the air disk is connected to a delivery pipe, a one-way valve is arranged on the delivery pipe, and an air pump is arranged on one side of the delivery pipe.

[0007] Preferably, a base is provided at the bottom of the quenching tank, and an air pump is installed on the base.

[0008] Preferably, a through hole is provided on the gas disk, and a baffle is hingedly connected to the inner side of the through hole.

[0009] Preferably, the baffles are symmetrically distributed on both sides about the bisector of the through hole, and the baffles are rotatably connected to the gas disk.

[0010] Preferably, a support spring is fixed to the inner wall of the through hole of the gas disk, and one end of the support spring is connected to the baffle.

[0011] Preferably, a quenching liquid inlet pipe is provided on one side of the quenching pool, and a quenching liquid outlet pipe is provided on the other side of the quenching pool.

[0012] Preferably, valves are provided on both the quenching liquid inlet pipe and the quenching liquid outlet pipe.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) This device can prevent the valve stem from colliding with the inner wall of the quenching pool, thereby preventing the valve stem from deforming.

[0015] (2) The device sets buffer components on the left and right sides of the inner wall of the quenching pool and on the bottom of the quenching pool. Gas at a certain pressure enters the quenching pool to push the quenching liquid in the quenching pool to flow, pushing the valve stem to the middle position of the quenching pool, preventing the valve stem from being too close to the inner wall of the quenching pool, thereby ensuring the safety of the valve stem entering the quenching pool.

[0016] (3) The device sets a one-way opening baffle and a one-way valve on the gas disk. The baffle can play a role in intercepting the quenching liquid to a certain extent, thereby preventing the quenching liquid from flowing out of the gas disk. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Working principle: When using the new quenching device, first, when the valve stem is added to the quenching pool 1, the air pumps 64 on the left and right sides of the inner wall of the quenching pool 1 and the buffer assembly 6 at the bottom of the quenching pool 1 are started. After starting, the air pump 64 delivers air of the same pressure to the inside of the delivery pipe 62. The air enters the inside of the gas disk 61 through the delivery pipe 62, and then pushes the baffle 65 inside the top through hole of the gas disk 61, so that the baffle 65 is opened by rotating through the hinge, and the support spring 66 connected to the bottom of the baffle 65 is in a stretched state. At this time, the gas enters the quenching pool 1 and pushes the quenching liquid inside the quenching pool 1 to flow, while concentrating the valve stem to the middle position of the quenching pool 1. When the quenching work is completed, the air pump 64 is turned off, and as the pressure decreases, the support spring 66 slowly contracts. During the contraction of the support spring 66, the baffle 65 is driven to rotate to close the top through hole of the gas disk 61.
