Description

Technical Field

[0001] The utility model relates to the technical field of rapid quenching equipment for high-speed steel processing, in particular to rapid quenching equipment for high-speed steel processing. Background Art

[0002] When high-speed steel is used as a raw material, its shapes are diverse, such as rods, bars, plates, wires, and strips. During the machining process, high-speed steel strips sometimes need to be quenched to increase their surface hardness. High-speed steel strips are widely used in many industries such as machinery manufacturing and military industry. During the quenching process, high-speed steel strips are generally conveyed through a transmission device, so that the high-speed steel strips are quenched while being conveyed, achieving the purpose of continuous high-frequency quenching. In order to meet the above processing needs, it is necessary to design a rapid quenching equipment for high-speed steel strip processing. Multiple and high-frequency quenching will increase the temperature of the quenching liquid. The lack of a structure to cool the quenching liquid will affect the quenching effect. The harmful gases generated during quenching lack a structure to collect and filter them. The harmful gases diffuse in the air and can damage the health of workers.

[0003] A rapid quenching device for high-speed steel processing disclosed in publication number CN217297928U, although the utility model clamps the high-speed steel placed on the support plate through two fixed clamping devices, the rotating rod drives the rotating block to rotate, the rotating block drives the screw to rotate, the moving block is restricted by the limit rod, and the moving block can only move left and right on the screw. At this time, the two moving blocks are brought close to each other, the moving block drives the fixed rod to move, and the fixed rod drives the clamping block to move, thereby achieving the purpose of clamping the high-speed steel placed between the two clamping blocks, which is convenient for subsequent operations and has high practicality.

[0004] However, this rapid quenching equipment for high-speed steel processing has the following disadvantages:

[0005] Multiple and high-frequency quenching will increase the temperature of the quenching liquid. The lack of a structure to cool the quenching liquid will affect the quenching effect.

[0006] There is no structure to collect and filter the harmful gases produced during quenching, and the harmful gases diffuse in the air, causing damage to the health of workers. Utility Model Content

It solves the problems raised in the above-mentioned background technology that there is a lack of structure to cool the quenching liquid, which affects the quenching effect, and there is a lack of structure to collect and filter the harmful gases generated during quenching.

[0008] To achieve the above objectives, the utility model is implemented through the following technical solutions: a rapid quenching equipment for high-speed steel processing, comprising a quenching tank, the bottom surface of the quenching tank is fixedly connected to a cooling assembly, the top surface of the quenching tank is fixedly connected to a smoke hood, the top surface of the smoke hood is provided with smoke outlets equidistantly from left to right, the top surface of the smoke outlet is fixedly connected to a smoking assembly, and both ends of the quenching tank are fixedly connected to sealing plates.

[0009] Optionally, the cooling assembly includes a circular tube fixedly connected to the bottom of the quenching tank, a plurality of semiconductor refrigeration plates are fixedly connected to the bottom of the circular tube, one end of the circular tube is connected to a connector, and a water inlet pipe is sleeved inside the connector.

[0010] Optionally, a cavity is provided inside the quenching tank, and the cavity is connected to the other end of the circular tube.

[0011] Optionally, the smoking assembly includes an impeller fixedly connected to the top surface of the smoke outlet, the top surface of the impeller is connected to the smoke collecting tube, the top end of the smoke collecting tube is sleeved with a limiting ring, and the interior of the limiting ring is sleeved with a filtering structure.

[0013] Optionally, a liquid outlet is provided on the top surface of the quenching tank and is connected to the cavity, and a stop valve pipe is connected to the top surface of the liquid outlet.

[0014] The utility model provides a rapid quenching equipment for high-speed steel processing, which has the following beneficial effects:

[0015] 1. The rapid quenching equipment for high-speed steel processing sets the cooling temperature of the semiconductor refrigeration plate through the setting of the cooling component. The cooling surface of the semiconductor refrigeration plate is attached to the bottom of the return tube. Then, the quenching liquid entering the return tube from the water inlet pipe is cooled before entering the quenching tank, thereby avoiding the effect of excessively high quenching liquid temperature in the quenching tank due to continuous quenching, which affects the quenching effect.

[0016] 2. The rapid quenching equipment for high-speed steel processing places the high-speed steel to be quenched from the side of the smoke hood into the quenching tank through the setting of the smoke collection component.
