Description

Technical Field

[0001] The utility model relates to the technical field of piston rod processing, in particular to a quenching device for piston rod processing. Background Technique

[0002] The piston rod is a connecting component that supports the piston to do work. Most of it is used in the moving components of oil cylinders and air cylinders. It is a moving component with frequent movement and high technical requirements. Quenching is to heat the steel to a certain temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), hold it for a period of time to make all or part of it austenitized, and then quickly cool it at a cooling rate greater than the critical cooling rate to below Ms (or isothermal near Ms) for martensite (or bainite) transformation heat treatment process. After the piston rod is processed, a quenching operation needs to be carried out to make the piston rod stronger.

[0003] The clamping structure of the existing quenching equipment adopts a hard clamping method. After clamping, the clamping structure will no longer move. At this time, if the clamping part is deformed, it will cause the clamping to loosen, resulting in the direct dropping of the component and affecting the quenching effect. Therefore, in view of the above defects, this application proposes a quenching device for piston rod processing. Content of the Utility Model

[0004] The purpose of the utility model is to provide a quenching device for piston rod processing to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: It includes a quenching box and a first clamping component. Above the quenching box, there is an upper frame, and a support guide rod is arranged at the lower end inside the upper frame. The first clamping component is located at one end of the support guide rod, and the first clamping component includes a moving plate, a telescopic rod, a telescopic sleeve, an air box, a connecting head, and a clamping head. The lower end of the moving plate is connected with the telescopic rod, and the end of the telescopic rod away from the moving plate is connected with the telescopic sleeve. The end of the telescopic sleeve away from the telescopic rod is connected with the air box, and a connecting head is arranged at the upper end of the air box. The end of the air box away from the telescopic sleeve is connected with the clamping head.

[0006] Preferably, a piston rod body is connected to the side of the first clamping component close to the central axis of the quenching box, and a second clamping component is connected to the end of the piston rod body away from the first clamping component.

[0007] Preferably, a motor is connected to the end of the second clamping component away from the piston rod body, and a clamping traction rope penetrates through the upper end of the second clamping component.

[0008] Preferably, a flame nozzle is installed through one side of the upper frame, and a pushing component is installed at the upper end of the upper frame.

[0009] Preferably, the pushing assembly includes a cylinder, a pushing plate and a spring. The upper end of the cylinder is connected to the pushing plate, and a spring is arranged in the middle of the upper end of the pushing plate.

[0010] Preferably, the pushing assembly further includes a guide rod, a connecting plate and a traction rod. Guide rods are connected to both sides of the upper end of the pushing plate. The upper end of the spring is connected to the connecting plate, and traction rods are connected to both sides of the connecting plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. During the working process of the device, heat will cause the gas inside the air box to expand, so that the telescopic rod extends from the telescopic sleeve, making the clamping of the clamping head more stable, and preventing the deformation of the clamping head after long-term use, which affects the clamping effect.

[0013] 2.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. 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 without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown in the figure, the present invention provides a technical solution: including a quenching tank 1 and a first clamping assembly 4. There is an upper rack 2 above the quenching tank 1, and a support guide rod 3 is arranged at the lower end inside the upper rack 2. The first clamping assembly 4 is located at one end of the support guide rod 3. The first clamping assembly 4 includes a moving plate 401, a telescopic rod 402, a telescopic sleeve 403, an air tank 404, a connector 405 and a clamping head 406. The lower end of the moving plate 401 is connected to the telescopic rod 402, and the end of the telescopic rod 402 away from the moving plate 401 is connected to the telescopic sleeve 403. The end of the telescopic sleeve 403 away from the telescopic rod 402 is connected to the air tank 404, and a connector 405 is arranged at the upper end of the air tank 404. The end of the air tank 404 away from the telescopic sleeve 403 is connected to the clamping head 406;

[0021] During the working process, heat will cause the gas inside the air tank 404 to expand, so that the telescopic rod 402 extends out of the telescopic sleeve 403, making the clamping of the clamping head 406 more stable, and preventing the deformation of the clamping head 406 after long-term use, which affects the clamping effect.

[0022] As Figure 1 and Figure 2 shown, a piston rod body 5 is connected to the side of the first clamping assembly 4 close to the central axis of the quenching tank 1. The end of the piston rod body 5 away from the first clamping assembly 4 is connected to a second clamping assembly 6. The end of the second clamping assembly 6 away from the piston rod body 5 is connected to a motor 7. A clamping traction rope 8 penetrates through the upper end of the second clamping assembly 6. A flame nozzle 9 is installed through one side of the upper rack 2, and a pushing assembly 10 is installed at the upper end of the upper rack 2;

[0023] The structures of the first clamping assembly 4 and the second clamping assembly 6 are the same. The motor 7 drives the second clamping assembly 6 to rotate, thereby driving the piston rod body 5 to rotate, making the heat evenly distributed. The flame nozzle 9 can continuously heat the piston rod body 5. The clamping traction rope 8 pulls the first clamping assembly 4 and the second clamping assembly 6 to realize the clamping of the piston rod body 5. The pushing assembly 10 controls the operation of the clamping traction rope 8.

[0024] As Figure 4As shown in the figure, the pushing component 10 includes a cylinder 1001, a pushing plate 1002 and a spring 1003. The upper end of the cylinder 1001 is connected to the pushing plate 1002, and the middle of the upper end of the pushing plate 1002 is provided with a spring 1003. The pushing component 10 further includes a guide rod 1004, a connecting plate 1005 and a traction rod 1006. The two sides of the upper end of the pushing plate 1002 are connected to the guide rod 1004, the upper end of the spring 1003 is connected to the connecting plate 1005, and the two sides of the connecting plate 1005 are connected to the traction rod 1006;

[0025] Relying on the elastic telescopic structure formed between the connecting plate 1005, the guide rod 1004 and the spring 1003 and the pushing plate 1002, the connecting plate 1005 will continuously drive the traction rod 1006 to push, so that the clamping traction rope 8 is formed with a continuous traction force, increasing the clamping stability of the equipment.

[0026] Working principle: First, place the piston rod body 5 between the second clamping component 6 and the first clamping component 4, then open the cylinder 1001 to push the pushing plate 1002, so that the traction rod 1006 drives the clamping traction rope 8 to traction the first clamping component 4 and the second clamping component 6, so that the first clamping component 4 and the second clamping component 6 move under the support of the support guide rod 3, so that the first clamping component 4 and the second clamping component 6 clamp the piston rod body 5. Relying on the elastic telescopic structure formed between the connecting plate 1005, the guide rod 1004 and the spring 1003 and the pushing plate 1002, the traction rod 1006 forms a continuous traction effect on the clamping traction rope 8, increasing the clamping effect of the equipment. Then open the flame spraying head 9 to heat the piston rod body 5, and then turn on the motor 7 to drive the second clamping component 6 to rotate, so that the second clamping component 6 drives the piston rod body 5 to rotate, facilitating the uniform heating of the piston rod body 5. During the heating process, the gas in the air box 404 is heated and expands, which will push the telescopic rod 402 inside the telescopic sleeve 403, so that the clamping head 406 is stressed, increasing the clamping stability of the clamping head 406 on the piston rod body 5. The rotational connection between the moving plate 401 and the telescopic rod 402 facilitates the rotation of the piston rod body 5. When the heating is completed, loosen the clamping through the cylinder 1001, so that the piston rod body 5 falls into the box body 101 for cooling, completing quenching.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
