[0002] The corrugation machine is a device that processes a straight metal tube into a cylindrical thin-walled elastic shell with transverse corrugations. Its main function is to create corrugations on the metal tube to increase the strength and rigidity of the tube, and it can also beautify the appearance.

[0003] The working principle of the corrugating machine is to press the metal pipe into a wave shape through a corrugating die. The corrugating die is usually composed of two upper and lower rollers. The metal pipe is pressed into a corrugated shape through the extrusion of the rollers. It is often used to manufacture products such as corrugated pipes and metal hoses.

[0004] The existing corrugating die of the corrugating machine usually uses two rollers to squeeze the tube wall of the metal tube to form a corrugated shape when pressing the metal tube. During the extrusion process, the metal tube may deviate from the extrusion position due to shaking, resulting in the problem that the corrugations of the manufactured metal corrugated tube are not uniform and the effect is poor. In view of this, we propose a corrugating die for the corrugating machine. Utility Model Content

[0030] like Figures 1 to 6 As shown, the utility model relates to a wave forming mold of a wave forming machine, comprising a support assembly 1 and a wave forming machine body 2, wherein the wave forming machine body 2 is arranged above the support assembly 1, and the wave forming machine body 2 comprises a wave forming assembly 3;

[0031] The support assembly 1 includes a table top 101, the bottom surface of the table top 101 is connected to a support side plate 102, and the side wall of the support side plate 102 is connected to a bottom plate 103;

[0032] The wave machine body 2 includes a motor 205 and a hydraulic cylinder 206 arranged on the top surface of the bottom plate 103, the output end of the motor 205 is connected to a screw rod 204, the output end of the hydraulic cylinder 206 is connected to a push-pull rod 211, the top surface of the table 101 is connected to a guide column 201 and four sliding columns 202, the circumferential side wall of the guide column 201 is provided with a moving disk 203, the top surface of the moving disk 203 is provided with a placement groove 209, the moving disk 203 is penetrated from top to bottom by a screw rod 204, and the top of the screw rod 204 is connected to a top cover plate 212;

[0033] In the embodiment of the utility model, by inserting the metal tube into the guide column 201 and inserting the bottom of the metal tube into the placement groove 209, the metal tube can be fixed to prevent the metal tube from shaking during the corrugation pressing process. Furthermore, the motor 205 drives the screw rod 204 to rotate, and the movable plate 203 is slowly raised during the rotation of the screw rod 204.

[0034] The wave-generating component 3 includes a fixed column 301 connected to the top of the guide column 201, a push groove 302 and a plurality of push holes 303 are provided on the circumferential outer wall of the fixed column 301, a plurality of push blocks 306 are arranged in the push groove 302, a push column 307 is connected to the side wall of the push block 306, the push column 307 passes through the push hole 303, a push plate 308 is connected to the end of the push column 307, a spring 304 is provided on the circumferential outer wall of the push column 307, a pressure block 305 is provided on the side wall of the push plate 308, and the bottom of the pressure block 305 is connected to the push-pull rod 211;

[0035] In the embodiment of the present invention, the push-pull rod 211 is driven by the hydraulic cylinder 206 to do an upward pushing and downward pulling movement. When pulling downward, the push-pull rod 211 pulls the pressure block 305 to move downward. During the downward pressing process of the pressure block 305, multiple push plates 308 are pressed, so that the push plates 308 move toward the circumferential inner wall of the fixed column 301, and the push column 307 is further moved outward from the push hole 303, driving the push block 306 to leave the push groove 302 and press toward the circumferential inner wall of the metal pipe. When the multiple push blocks 306 contact the circumferential inner wall of the metal pipe, the metal pipe can be positioned and fixed to prevent it from shaking. As the pressure block 305 continues to press downward, it drives the multiple push blocks 306 to gradually press outward around the circumferential inner wall of the metal pipe, pressing the side wall of the metal pipe into a corrugated shape. The metal tube is unlikely to shake, which is beneficial to the stability of the pressing process and achieves a better pressing effect. After the pressing is completed, the hydraulic cylinder 206 drives the push-pull rod 211 to do an upward pushing movement, and the pull rod 211 pushes the pressing block 305 to move upward, so that the push plate 308 loses the pressure applied by the pressing block 305. At this time, the push plate 308 is subjected to the elastic force of the spring 304 and moves toward the inside of the fixed column 301, driving the push block 306 back into the push groove 302, and further drives the screw rod 204 to rotate through the motor 205. During the rotation of the screw rod 204, the movable disk 203 slowly rises, driving the metal tube to rise, and the next corrugation is pressed on the metal tube. In this way, multiple corrugations are pressed on the metal tube, and the pressing process is stable, so that the corrugations after pressing are more uniform.

[0036] Specifically, the guide column 201 is a hollow tubular structure, the bottom surface of the guide column 201 is fixed to the top surface of the table 101 by bolts, the push-pull rod 211 passes through the table 101 and extends to the internal space of the guide column 201, and the hollow tubular structure of the guide column 201 provides movement space for the push-pull rod 211.

[0037] Furthermore, the movable plate 203 is penetrated from top to bottom by a guide column 201 and four slide columns 202 , and the holes of the movable plate 203 are slidably connected to the circumferential outer walls of the guide column 201 and the slide column 202 , so as to facilitate the movable plate 203 to move up and down.

[0038] It is worth noting that the movable plate 203 and the screw rod 204 are threadedly connected, and the top of the screw rod 204 and the bottom surface of the top cover plate 212 are rotatably connected, so that the screw rod 204 can rotate and drive the movable plate 203 to move up and down.

[0039] It is worth noting that the fixing column 301 is a hollow tubular structure, and the bottom of the fixing column 301 is threadedly connected to the inner wall of the circumference of the guide column 201. The threaded connection is convenient for disassembly and maintenance of the wave generator component 3.

[0040] It is worth mentioning that a fixed bottom plate 207 is provided on the circumferential outer wall of the guide column 201, and the bottom surface of the fixed bottom plate 207 is connected to the top surface of the movable disk 203. An outer plate 208 and an inner plate 210 are provided on the bottom surface of the fixed bottom plate 207. A placement groove 209 is formed between the side wall of the outer plate 208 and the side wall of the inner plate 210. The placement groove 209 can play a role in positioning and fixing the metal pipe placed therein through the outer plate 208 and the inner plate 210.

[0041] In addition, one end of the spring 304 is connected to the circumferential inner wall of the fixed column 301, and the other end of the spring 304 is connected to the side wall of the push plate 308. The spring 304 cooperates with the inner wall of the fixed column 301 to exert an elastic force on the push plate 308, which is conducive to the push plate 308 being reset by the elastic force.

[0042] Secondly, the pressing block 305 is the shape of a cone without a cone head, and the inner cavity shape of the fixed column 301 matches the shape of the pressing block 305, which is conducive to the pressing process of the pressing block 305. The inner cavity space of the fixed column 301 gradually decreases toward the inner wall, making it convenient to press the push plate 308 to move it toward the circumferential inner wall of the fixed column 301.

[0043] Finally, the side wall of the push plate 308 is an inclined arc surface structure, and the side wall of the push plate 308 fits with the side wall of the pressure block 305, so that the side wall of the pressure block 305 can better push the push plate 308 to move during the downward movement of the pressure block 305. The side wall of the push block 306 is a semi-circular arc surface structure, which is conducive to pressing the metal tube into a more uniform corrugated shape, and the arc surface structure is not easy to crush the tube wall of the metal tube.

[0044] Working principle: This embodiment provides a wave forming mold of a wave forming machine. When in use, the metal tube is inserted into the guide column 201, the bottom of the metal tube is inserted into the placement groove 209, and the push-pull rod 211 is driven by the hydraulic cylinder 206 to push up and pull down. When pulling down, the push-pull rod 211 pulls the pressing block 305 to move downward. During the downward pressing process of the pressing block 305, multiple push plates 308 are pressed, so that the push plates 308 move toward the circumferential inner wall of the fixed column 301, and further the push column 307 moves outward from the push hole 303, driving the push block 306 to leave the push groove 302 and press toward the circumferential inner wall of the metal tube. As the pressing block 305 continues to press downward, multiple push blocks 306 are driven to move. 6 The inner wall of the circle around the metal tube is gradually pressed outward, and the side wall of the metal tube is pressed to form a corrugated shape. After the pressing is completed, the hydraulic cylinder 206 drives the push-pull rod 211 to push upward, and the pull rod 211 pushes the pressing block 305 to move upward, so that the push plate 308 loses the pressure applied by the pressing block 305. At this time, the push plate 308 is affected by the elastic force of the spring 304 and moves toward the inside of the fixed column 301, driving the push block 306 back to the push groove 302, and further drives the lead screw 204 to rotate through the motor 205. During the rotation of the lead screw 204, the movable plate 203 slowly rises, driving the metal tube to rise, and the next corrugation pressing work is performed on the metal tube.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
