Description

Technical Field

[0001] This utility model relates to the field of steel cylinder processing technology, specifically to a cooling device for steel cylinder stamping production. Background Technology

[0002] In the stamping production of high-pressure gas cylinders, the cooling device plays a crucial role in ensuring product quality and production efficiency. Because the cylinders must withstand high pressure, their production process is extremely demanding, making cooling indispensable. Appropriate cooling temperatures can prevent cracking and other phenomena during stamping, effectively improving the yield rate.

[0003] Currently, there are significant problems with the piping arrangement connecting the cooling equipment and the upper die in the cylinder stamping unit. To prevent the piping from entering the stamping area, it is typically fixed to the upper die at a point. However, the upper die operates in a high-frequency reciprocating motion, causing the piping connection points to be subjected to repeated bending forces. Over time, this makes the piping highly susceptible to breakage due to material fatigue.

[0004] If a pipeline breaks, it will not only cause leakage of the cooling medium, affecting the cooling effect and thus reducing the quality of cylinder stamping production, but may also cause production stoppages, increasing maintenance and time costs, and seriously affecting the continuity and stability of production. Therefore, a cooling device for cylinder stamping production is proposed to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a cooling device for steel cylinder stamping production. This device solves the technical problem mentioned in the background art: to prevent the pipes connecting the cooling equipment of the steel cylinder stamping device to the upper mold from entering the stamping area, most of the pipes are fixed to the upper mold at points. During the reciprocating lifting and lowering process of the upper mold, the pipe connection points are prone to repeated bending, which leads to material fatigue and breakage of the pipes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for steel cylinder stamping production, comprising:

[0007] The refrigeration unit is equipped with an air supply port;

[0008] The winding drum has a hollow structure and is rotatably mounted on the refrigeration unit. The air supply port is located inside the winding drum, and the winding drum is also connected to an air outlet.

[0009] The cooling pipe is connected at one end to the stamping machine and at the other end to the winding drum and fixedly connected to the air outlet.

[0010] A support wheel is rotatably mounted on the refrigeration unit, and the cooling pipes are mounted on the support wheel; and

[0011] A reset assembly is disposed on the winding drum and connected to the refrigeration unit to drive the winding drum to reset after it rotates.

[0012] In a preferred embodiment, a connecting flange is provided on one side of the refrigeration unit, and a retaining ring is provided on the connecting flange. An annular retaining bracket is provided on one side of the winding drum, and the retaining bracket is engaged with the retaining ring.

[0013] In a preferred embodiment, a support rod is provided on the connecting flange, a support frame is slidably sleeved on the support rod, a set screw is screwed onto the support frame, the end of the set screw abuts against the support rod, and a support wheel is rotatably mounted on the support frame.

[0014] In a preferred embodiment, the air outlet is provided with a screw-in connector, and one end of the cooling pipe is detachably connected to the connector.

[0015] In a preferred embodiment, the reset assembly includes a constant force spring, a mounting bracket is provided on one side of the refrigerator, one end of the winding drum is rotatably disposed in the mounting bracket, one end of the constant force spring is fixedly connected to the winding drum, and the other end is fixedly connected to the mounting bracket.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This device uses a refrigeration unit for cooling. If gas cooling is used, cold air is delivered to the upper die of the stamping machine through the winding drum and cooling pipes. If liquid cooling is used, a cold water pipe runs through the winding drum and cooling pipes and connects to the upper die. During the reciprocating motion of the upper die, support wheels support the cooling pipes, preventing them from entering the stamping machine. The cooling pipes drive the winding drum to rotate, and the drum can be reset by a reset component after rotation. This allows the cooling pipes to adapt to the movement of the upper die and keeps them taut at all times. This transforms the traditional single-point stress into overall stress on the cooling pipes, effectively preventing material fatigue caused by prolonged reciprocating bending at a single point, reducing wear, increasing service life, and eliminating the need for frequent pipe replacements.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0025] Example:

[0026] like Figures 1 to 3 As shown, this utility model provides a cooling device for steel cylinder stamping production, including a refrigeration unit 1. A gas supply port 2 is provided on one side of the refrigeration unit 1, through which the cold air or coolant produced by the refrigeration unit 1 can be discharged. A winding drum 10 is rotatably mounted on the refrigeration unit 1. The winding drum 10 has a hollow structure, and the gas supply port 2 is located inside the winding drum 10. An outlet 12 is also connected to the winding drum 10. One end of a cooling pipe 14 is connected to the stamping machine. A screw-connected connector 13 is provided on the outlet 12. One end of the cooling pipe 14 is wound around the winding drum 10 and detachably connected to the connector 13. If gas cooling is used, cold air can enter the winding drum 10 and then enter the cooling pipe 14 through the connector 13 until it is supplied to the press for cooling. The rotation of the winding drum 10 does not affect the flow of gas. If coolant cooling is used, the coolant water pipe can be connected to the press through the winding drum 10 and the cooling pipe 14, and a certain length of coolant water pipe is reserved inside the winding drum 10 to provide a certain space for the reciprocating rotation of the winding drum 10.

[0027] like Figure 2 , 3As shown, in this embodiment, a connecting flange 4 is provided on one side of the refrigeration unit 1, and a retaining ring 5 is provided on the connecting flange 4. An annular retaining bracket 11 is provided on one side of the winding drum 10, and the retaining bracket 11 is engaged with the retaining ring 5. The winding drum 10 is rotatably mounted to the refrigeration unit 1 through the engagement of the retaining bracket 11 and the retaining ring 5. A support wheel 9 is rotatably mounted on the refrigeration unit 1. The cooling pipe 14 is mounted on the support wheel 9. A support rod 6 is mounted on the connecting flange 4. A support frame 7 is slidably mounted on the support rod 6. A set screw 8 is screwed onto the support frame 7. The end of the set screw 8 abuts against the support rod 6. The support wheel 9 is rotatably mounted on the support frame 7. By setting the support wheel 9, the middle section of the cooling pipe 14 can be supported, effectively preventing the cooling pipe 14 from scattering and entering the stamping machine. Furthermore, by sliding the support frame 7 on the support rod 6 and fixing the position of the support frame 7 with the set screw 8, the support wheel 9 can be adjusted to the middle height of the upper die lifting stroke of the stamping machine. This allows the upper die of the stamping machine to pull the cooling pipe 14 with the shortest distance during the lifting process, reducing the rotation angle of the winding drum 10.

[0028] like Figure 1 , 2 As shown, a reset assembly connected to the refrigeration unit 1 is provided on the winding drum 10. The reset assembly drives the winding drum 10 to reset after it rotates. The reset assembly includes a constant force spring 15. A mounting bracket 3 is provided on one side of the refrigeration unit 1. One end of the winding drum 10 is rotatably mounted in the mounting bracket 3. One end of the constant force spring 15 is fixedly connected to the winding drum 10, and the other end is fixedly connected to the mounting bracket 3.

[0029] When the upper die of the stamping press moves, it drives the winding drum 10 to rotate through the cooling pipe 14. During the rotation of the winding drum 10, the constant force spring 15 is deformed. Then, when the upper die is raised and lowered to be flush with the support wheel 9, the winding drum 10 is reversed under the action of the constant force spring 15, so that the cooling pipe 14 is always in a taut state. This effectively prevents the cooling pipe 14 from loosening and entering the stamping press. At the same time, it transforms the traditional single-point force into the whole force of the entire cooling pipe 14, making the force more uniform, avoiding material fatigue, reducing wear, and improving the service life of the cooling pipe 14.

[0030] The specific usage and beneficial effects of this utility model are as follows:

[0031] The device uses a chiller 1 for cooling during operation. If gas cooling is used, cold air is delivered to the upper die of the stamping machine through the winding drum 10 and cooling pipe 14 for cooling. If liquid cooling is used, a cold water pipe runs through the winding drum 10 and cooling pipe 14 and connects to the upper die of the stamping machine. During the reciprocating lifting and lowering process of the upper die, the cooling pipe 14 is supported by support wheels 9 to prevent it from entering the stamping machine. The cooling pipe 14 drives the winding drum 10 to rotate. After rotation, the winding drum 10 can be reset by a reset component, allowing the cooling pipe 14 to adapt to the movement of the upper die and keeping it taut at all times. This transforms the traditional single-point force application into overall force application for the cooling pipe 14, effectively preventing material fatigue caused by prolonged reciprocating bending of a single point, reducing wear, increasing the service life of the cooling pipe 14, and eliminating the need for frequent replacement.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
