Description

Technical Field

[0001] The utility model belongs to the technical field of casting quenching, and particularly relates to an ADI material quenching device for an oil crosshead. Background Art

[0002] Quenching refers to a metal heat treatment process in which a metal workpiece is heated to an appropriate temperature and held for a period of time, and then immediately immersed in a quenching medium for rapid cooling. After quenching, the hardness and wear resistance of the metal workpiece are greatly improved, so it is widely used in various tools, dies, measuring tools and parts requiring surface wear resistance.

[0003] During quenching, the uniformity of the temperature of the quenching medium in the quenching pool and the cooling rate determine the mechanical properties of the quenched parts. This requires that the quenching system has the quenching liquid flowing in the quenching tank. At present, at home and abroad, the stirring of the quenching pool mostly adopts the installation of rotating blades at the bottom of the pool, and the motor drives the blades to rotate to circulate the quenching liquid. The method of bottom stirring in the pool has high requirements for the depth of the quenching pool. And when repairing the rotating blades, it is necessary to transfer all the quenching medium in the quenching pool, which makes the repair time-consuming and difficult.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present invention.

It is only for the convenience of describing the present utility model and does not require the present utility model to be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. The terms "connected" and "coupled" used in the present utility model should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be directly connected or indirectly connected through an intermediate component. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0027] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.

[0028] As Figures 1-3 shown, a quenching device for ADI material of a petroleum crosshead includes a quenching tank, a suction pipe, a diversion pipe, and a partition. The two suction pipes are respectively located at opposite ends of the quenching tank. For example, the quenching tank is rectangular, and the two suction pipes are located at both ends in the length direction of the quenching tank and extend along the width direction of the quenching tank. The length of the suction pipe is adapted to the width of the quenching tank. After the two suction pipes extend out of the quenching tank, they are correspondingly connected to the water inlet end of the circulation pump through a tee pipe.

[0029] The two diversion pipes are spaced apart and distributed in the middle of the quenching tank. Correspondingly, the diversion pipes extend along the width direction of the quenching tank. After the two diversion pipes extend out of the quenching tank, they are correspondingly connected to the water outlet end of the circulation pump through a tee pipe, so as to form an internal circulation of the quenching liquid after the circulation pump is started, ensuring that the quenching liquid can keep the temperature of the quenching liquid around the workpiece at a lower temperature through circulation, thereby improving the quenching efficiency and quality.

[0030] This application is mainly for quenching of smaller products (petroleum crossheads). Therefore, multiple products need to be quenched at one time. For this need, this application supports multiple workpiece products through a partition, so that multiple workpieces can be quenched simultaneously. The partition is adapted to the shape of the inner cavity of the quenching tank and is hung on the side wall of the quenching tank through a connecting piece to be horizontally arranged above the suction pipe, so as not to collide with the suction pipe. The partition is a grid structure welded by square pipes, so that the quenching liquid can flow up and down through the partition, ensuring that the quenching liquid at all angles circulates in the quenching tank without being interfered by the partition.

[0031] In an alternative embodiment, the connecting member is a piston rod, such as an oil cylinder or a pneumatic cylinder. The piston end of the piston rod is perpendicular to the partition plate and is fixed to the partition plate by means of welding, bolts, etc. Hooks corresponding to the side wall of the quenching tank are provided on the cylinder body of the piston rod, thereby restricting the height of the partition plate and enabling adjustment of the position of the partition plate according to actual requirements. During the quenching process, the piston rod is used to drive the partition plate to move up and down longitudinally, thereby improving the circulation effect.

[0032] In this embodiment, four piston rods are provided. The four piston rods are located at the four corners of the partition plate, thereby enabling support and drive of the partition plate. The hooks are provided with hanging holes, through which the partition plate can be lifted by a crane.

[0033] In an alternative embodiment, a sleeve for sleeving the piston rod is provided on the partition plate. The length of the sleeve is less than the length of the piston rod after the piston end is retracted, thereby protecting the piston rod from being eroded by the quenching liquid or the heat of the workpiece.

[0034] In an alternative embodiment, the bottom of the quenching tank is provided with a V-shaped bottom. The V-shaped bottom can collect and guide the sediment during the quenching process. A slag discharge pipe extending along the length direction of the quenching tank is provided at the V-shaped bottom. The slag discharge pipe is located at the lowest point of the V-shaped bottom, and slag discharge holes are evenly distributed on its outer wall. A valve is connected to one end of the slag discharge pipe after it extends out of the quenching tank. After the valve is opened, under the action of water pressure, the quenching liquid mixed with sediment can be discharged. Baffles are provided at both ends of the quenching tank between the V-shaped bottom and the suction pipe, thereby preventing the suction pipe from sucking out the sediment at the bottom. Filter meshes corresponding to the suction pipes are provided at both ends of the quenching tank, thereby preventing sediment or other sundries from entering the circulation pump.

[0035] In an alternative embodiment, uniformly distributed nozzles are provided on the diversion pipe. The nozzles are located on the adjacent sides of the two diversion pipes and extend obliquely upward, thereby discharging the water led out to both ends and above the partition plate to ensure that the water can flow in time to carry away heat.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are within the scope of the claims of the present invention awaiting approval.
