Description

Technical Field

[0001] This utility model belongs to the field of transmission shaft manufacturing technology, and specifically relates to a heat treatment cooling device for transmission shaft manufacturing. Background Technology

[0002] The heat treatment cooling system for drive shaft production is specifically designed for the rapid and uniform cooling of drive shafts after heat treatment. Its purpose is to adjust the microstructure of the material by controlling the cooling rate, thereby achieving the desired mechanical properties (such as hardness and strength). Common cooling methods include water spray cooling, oil cooling, and air cooling.

[0003] Existing heat treatment cooling devices for drive shaft production use spray nozzles to cool the drive shaft during the conveying process by spraying water. However, because the position of the spray nozzles is fixed, the amount of water contacted between the upper and lower sides of the drive shaft is uneven when spraying water to cool it. This results in uneven cooling on both sides of the drive shaft, leading to unsatisfactory cooling effect and inconsistent cooling rates. This can easily cause local stress concentration and deformation. Such uneven cooling can also cause a large temperature gradient inside the drive shaft, affecting the final microstructure and mechanical properties. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a heat treatment cooling device for transmission shaft production. The upper nozzle can continuously swing back and forth, working in conjunction with the lower nozzle to spray water, which can quickly and evenly cool the transmission shaft during the conveying process, ensuring that all parts receive the same cooling effect. Through uniform cooling, the temperature difference inside the transmission shaft can be effectively reduced, avoiding stress concentration and deformation caused by local overcooling or overheating.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a heat treatment cooling device for transmission shaft production, including a roller conveyor, a mounting frame plate at the upper end of the roller conveyor, multiple hollow blocks rotatably arranged inside the mounting frame plate via a rotating column, multiple upper water spray holes at the lower end of each hollow block, and upper water spray heads arranged inside each of the multiple upper water spray holes, a collection box at the lower end of the roller conveyor, a hollow frame inside the collection box, multiple lower water spray holes at the upper end of the hollow frame, and lower water spray heads arranged inside each of the multiple lower water spray holes, and a drive mechanism inside the mounting frame plate. The drive mechanism can drive the upper spray head to reciprocate. The drive mechanism includes a slide rail frame set inside the upper part of the mounting frame. Multiple sliding blocks are slidably arranged inside the slide rail frame. Each of the multiple rotating columns has a slide groove frame at its right end. The multiple sliding blocks are slidably connected to the adjacent slide groove frames. A lead screw is rotatably arranged inside the slide rail frame. Each of the multiple sliding blocks is threadedly connected to a lead screw. A drive unit for driving the lead screw to rotate is set on the rear side of the mounting frame. The drive unit includes a motor set on the rear side of the mounting frame. The output shaft of the motor passes through the mounting frame and is connected to the rear end of the lead screw through a coupling.

[0006] As a further improvement of this utility model, a water inlet pipe is provided in the through hole opened on the front side of the cavity frame, and the collection box is provided with a clearance hole corresponding to the position of the water inlet pipe.

[0007] As a further improvement of this utility model, a support frame is provided at the lower end of the roller conveyor, and multiple support feet are provided at the lower end of the support frame. The support frame and the support feet are fixed together by welding.

[0008] As a further improvement of this utility model, a water outlet pipe is provided in the water outlet hole at the lower end of the collection box, and a solenoid valve is connected in series in the middle of the water outlet pipe.

[0009] As a further improvement of this utility model, each of the water inlet holes opened at the upper end of the cavity frame is equipped with a connecting telescopic hose.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] Firstly, by controlling the start of the roller conveyor, personnel place the drive shaft that needs to be cooled on the rotating roller of the roller conveyor, so that the drive shaft moves between the cooling water sprayed from the upper and lower water spray heads, thereby quickly and efficiently cooling the drive shaft.

[0012] Secondly, by controlling the forward and reverse operation of the motor, the output shaft drives the lead screw to rotate, which in turn drives the sliding block inside the slide rail frame to move back and forth. Through the sliding rotation relationship of the sliding block on the slide rail frame, the rotating column on the slide rail frame rotates back and forth, causing the upper water spray head at the lower end of the cavity block to swing back and forth about 30 degrees. The upper spray head can continuously swing back and forth, and together with the water spray from the lower spray head, it can quickly and evenly cool the drive shaft during the conveying process, ensuring that all parts can obtain the same cooling effect. Through uniform cooling, the temperature difference inside the drive shaft can be effectively reduced, avoiding stress concentration and deformation caused by local overcooling or overheating.

[0013] Third, the sprayed cooling water can be collected inside the collection tank. Personnel can open the solenoid valve to discharge the collected cooling water from the outlet pipe, making it easy for personnel to recycle and thus save water resources. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 1, 2 As shown in Figure 3, a heat treatment cooling device for drive shaft production includes a roller conveyor 101. A mounting frame plate 201 is provided at the upper end of the roller conveyor 101. Multiple hollow blocks 208 are rotatably arranged inside the mounting frame plate 201 via a rotating column. Multiple upper water spray holes are opened at the lower ends of the multiple hollow blocks 208, and upper water spray heads 206 are provided inside the multiple upper water spray holes. A collection box 301 is provided at the lower end of the roller conveyor 101, and a hollow frame is provided inside the collection box 301. 303, the upper end of the cavity frame 303 is provided with multiple downward water spray holes, and each of the multiple downward water spray holes is provided with a downward water spray head 304. The interior of the mounting frame plate 201 is provided with a drive mechanism, which can drive the upper water spray head 206 to swing back and forth. The water inlet hole at the upper end of the cavity frame 303 is provided with a connecting telescopic hose 202. The through hole on the front side of the cavity frame 303 is provided with a water inlet pipe 302. The collection box 301 is provided with a clearance hole corresponding to the position of the water inlet pipe 302.

[0022] like Figure 2 , 3 As shown in Figure 4, the drive mechanism includes a slide rail frame 204 disposed on the upper part of the mounting frame 201. Multiple sliding blocks 209 are slidably disposed inside the slide rail frame 204. Each of the multiple rotating columns is provided with a slide groove frame 205 at its right end. The rotating columns and the slide groove frame 205 are fixed together by welding. The multiple sliding blocks 209 are slidably connected to the interior of the adjacent slide groove frame 205. A lead screw 207 is rotatably disposed inside the slide rail frame 204. Each of the multiple sliding blocks 209 is threadedly connected to a lead screw 207. A drive unit for driving the lead screw 207 to rotate is disposed on the rear side of the mounting frame 201. The drive unit includes a motor 203 disposed on the rear side of the mounting frame 201. The output shaft of the motor 203 passes through the mounting frame 201 and is connected to the rear end of the lead screw 207 through a coupling.

[0023] like Figure 1 As shown, a support frame 102 is provided at the lower end of the roller conveyor 101. The lower end of the support frame 102 is provided with multiple support feet, which can realize stable support for the cooling device and ensure the quality of cooling of the transmission components.

[0024] When the drive shaft needs to be cooled during the production process, the operator connects the telescopic hose 202 to an external water source, allowing the external water source to deliver water into the cavity block 208. The cooling water is then continuously sprayed out through the upper spray head 206. Then, the water inlet pipe 302 is connected to the external water source, allowing the external water source to enter the cavity frame 303. The cooling water is then continuously sprayed out through the lower spray head 304. Next, the roller conveyor 101 is started by controlling it to run. The operator then places the drive shaft to be cooled on the rotating roller of the roller conveyor 101, so that the drive shaft moves between the cooling water sprayed from the upper spray head 206 and the lower spray head 304, thereby achieving the cooling of the drive shaft.

[0025] When cooling the drive shaft, the motor 203 can be turned on to run in both directions. The output shaft drives the lead screw 207 to rotate, which in turn drives the sliding block 209 inside the slide rail frame 204 to move back and forth. Through the sliding rotation relationship of the sliding block 209 in the slide rail frame 205, the rotating column on the slide rail frame 205 rotates back and forth, and the upper water spray head 206 at the lower end of the cavity block 208 swings back and forth about 30 degrees, so as to achieve uniform spraying of cooling water to cool the drive shaft.

[0026] According to another embodiment of the present invention, such as Figure 1 , 2 As shown in Figure 3, a water outlet pipe 305 is installed in the water outlet hole at the lower end of the collection box 301. A solenoid valve 306 is connected in series in the middle of the water outlet pipe 305. The sprayed cooling water can be collected inside the collection box 301. Personnel can open the solenoid valve 306 by controlling it to discharge the collected cooling water from inside the water outlet pipe 305, which is convenient for personnel to recycle.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
