Description

Technical Field

[0001] This utility model relates to the technical field of quenching water spray boxes, specifically a quenching water spray box with a water removal mechanism. Background Technology

[0002] The quenching water spray box is mainly used for water cooling of workpieces after quenching. Patent No.: CN202022052595.9, Patent Name: A High-Stability Quenching Device for Automobile Half Shafts. This patent uses a lifting slide to drive the heating structure and water spraying structure to heat the half shaft clamped on the upper and lower centers, and then spray water to cool it. However, this patent does not dry the half shaft after spraying water. When the operator opens the quenching chamber door, water droplets inside the quenching chamber will drip onto the operator's clothes, wetting them. Moreover, water droplets on the outer surface of the half shaft will cause the operator to slip when picking it up, causing the half shaft to fall and resulting in damage to the outer surface of the half shaft or injury to the operator. At the same time, water droplets on the half shaft will also cause water to be everywhere at the workstation where the half shaft is placed, affecting the operator's movement. In addition, water on the ground can also cause safety accidents. Therefore, a quenching water spray box with a water removal mechanism is proposed. Utility Model Content

[0003] The main purpose of this utility model is to provide a solution that can effectively address the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a quenching water spray box with a water removal mechanism, comprising a water spray box body, wherein the water spray box body includes an inner cylinder and an outer cylinder and upper and lower end plates connecting the inner cylinder and the outer cylinder, wherein a hollow cavity is formed between the inner cylinder and the outer cylinder, characterized in that: a plurality of water pipes and a plurality of air pipes are connected to the outer cylinder, and a plurality of spray holes for spraying water and air are provided on the inner cylinder.

[0005] Preferably, the water spray box body has a ring structure.

[0006] Preferably, the end of the water spray hole near the outer cylinder is higher than the end near the inner cylinder.

[0007] Preferably, the water pipes and air pipes are spaced apart on the outer cylinder.

[0008] This utility model has the following beneficial effects: By setting water pipes and air pipes on the outer cylinder of the water spray box body, after the workpiece is quenched, the water pipe on the outer cylinder of the water spray box body is first connected to a water supply pump. Water enters the hollow cavity of the water spray box body from the water pipe. The hollow cavity is designed to generate pressure in the water entering the hollow cavity. The faster the water enters, the greater the pressure. The water is then sprayed out from the spray hole on the inner cylinder of the water spray box body towards the workpiece to cool it. After the workpiece is cooled, the air pipe on the outer cylinder of the water spray box body is connected to an air pump. Gas enters the hollow cavity from the air pipe and is then sprayed onto the workpiece from the spray hole. This allows the water droplets remaining on the workpiece to be dried quickly, preventing the workpiece from slipping and falling due to water droplets on the surface when the operator picks it up, which could damage the workpiece surface or hit the operator. It also keeps the ground where the workpiece is placed dry, increasing the safety of the production site.

[0009] By setting the end of the spray hole near the outer cylinder higher than the end near the inner cylinder, the water and gas entering the hollow cavity of the water spray box body can be sprayed downwards along the slope of the spray hole, which guides the flow direction and prevents water or gas from splashing upwards.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figure 1-2As shown, a quenching water spray box with a water removal mechanism includes a water spray box body 1. The water spray box body 1 includes an inner cylinder 2 and an outer cylinder 3, as well as upper and lower end plates 4 connecting the inner cylinder 2 and the outer cylinder 3. A hollow cavity 5 is formed between the inner cylinder 2 and the outer cylinder 3. The outer cylinder 3 is characterized by having several water pipes 6 and several air pipes 7 connected to it, and the inner cylinder 2 having several spray holes 8 for spraying water and air. By setting water pipes 6 and air pipes 7 on the outer cylinder 3 of the water spray box body 1, after the workpiece is quenched, the water pipes 6 on the outer cylinder 3 of the water spray box body 1 are first connected to a water pump, and water enters the hollow cavity 5 of the water spray box body 1 from the water pipes 6. In the process, the hollow cavity 5 creates pressure on the water entering it. The faster the water enters, the greater the pressure. The water is then sprayed onto the workpiece through the spray hole 8 on the inner cylinder 2 of the spray box body 1 to cool it. After the workpiece is cooled, the air pipe 7 on the outer cylinder 3 of the spray box body 1 is connected to an air pump. Gas enters the hollow cavity 5 through the air pipe 7 and is then sprayed onto the workpiece through the spray hole 8. This allows the residual water droplets on the workpiece to be quickly dried, preventing the workpiece from slipping and falling when the operator picks it up, which could damage the workpiece or injure the operator. It also keeps the ground where the workpiece is placed dry, increasing the safety of the production site.

[0015] In one embodiment, the water spray box body 1 is a ring structure, coaxially arranged with the quenching device, and can move up and down with the quenching device.

[0016] In one embodiment, the end of the spray hole 8 near the outer cylinder 3 is higher than the end near the inner cylinder 2. By setting the end of the spray hole 8 near the outer cylinder 3 to be higher than the end near the inner cylinder 2, water and gas entering the hollow cavity 5 of the water spray box body 1 can be sprayed downwards along the slope of the spray hole 8, which serves to guide the flow direction and prevent water or gas from splashing upwards.

[0017] In one embodiment, the water pipe 6 and the air pipe 7 are spaced apart on the outer cylinder 3.

[0018] When using this utility model, the water pipe 6 on the outer cylinder 3 of the water spray box body 1 needs to be connected to the water supply pump, and the air pipe 7 needs to be connected to the air pump. The water spray box body 1 is coaxial with the quenching device and can move with the quenching device. After the quenching device completes the quenching process of the workpiece, the water supply pump is first driven to supply water to the water pipe 6, so that the water enters the hollow cavity 5 of the water spray box body 1 from the water pipe 6. Then, water is sprayed onto the workpiece along the spray hole 8 on the inner cylinder 2, which is higher at one end and lower at the other, until the workpiece is cooled. Then, the air pump supplies air to the air pipe 7, and the air enters the hollow cavity 5 of the water spray box body 1. Then, air is sprayed onto the workpiece through the spray hole 8 until the water droplets remaining on the surface of the workpiece are dried.

[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
