[0002] The metal products industry includes structural metal products manufacturing, metal tool manufacturing, container and metal packaging container manufacturing, stainless steel and similar daily metal products manufacturing, etc. With the progress of society and the development of science and technology, metal products are used more and more widely in industry, agriculture and various fields of people's lives, and they also create more and more value for society. Metal processing is divided into many different manual methods, such as casting, which means that the metal is heated and melted, and then poured into the model, which is suitable for processing parts with complex shapes.

[0003] For example, the public document with application number 202122194133.5 discloses a calendering device for metal products. The utility model facilitates the adjustment of the distance between the calendering rollers and is simple to operate. The cooling structures distributed up and down cool it down to avoid damage caused by overtemperature, thereby improving the utilization efficiency of the calendering device. However, in the calendering device for metal products, the calendering rollers are belt-driven to each other. When adjusting the upper and lower calendering rollers, reducing the distance between the calendering rollers will keep the circumference between the belts unchanged, that is, the belts will be redundant and difficult to stably fit the pulley surface, which in turn leads to the inability to effectively transmit the transmission, affecting the stable rotation of the calendering rollers.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a rolling device for metal products is proposed. Utility Model Content

A groove 10 is provided on the surface of the pulley 8, and a groove 10 is provided on the upper right side of the surface of the left support plate 2 above the surface of the base 1, and a through cavity 11 is provided on the surface of the right support plate 2, and the size and position of the groove 10 and the through cavity 11 are the same, and a screw rod 12 is provided on the inner surface of the groove 10 through a bearing, and a guide block 13 is provided on the inner surface of the through cavity 11 for sliding fit, and the surface of the screw rod 12 is located in the inner thread connection of the groove 10 with an internal threaded hole block 14, and the right end of the internal threaded hole block 14 is provided with a movable calendering roller 15 through a bearing, and the right end of the movable calendering roller 15 is also rotatably connected with the guide block 13 through a bearing, and the support plate The surface of the support plate 2 is opposite to the side thereof, and a positioning calendering roller 16 is rotatably arranged below the groove 10 and the through cavity 11 through a bearing, and the positioning calendering roller 16 and the movable calendering roller 15 are of the same size and shape, and the right ends of the positioning calendering roller 16 and the movable calendering roller 15 respectively penetrate the support plate 2 and the guide block 13 and are fixedly connected to the corresponding pulleys 8 on the upper and lower sides, and the left end of the positioning calendering roller 16 penetrates the left support plate 2 and is provided with a driving motor 17, and a guide plate 18 is fixedly installed in front of the positioning calendering roller 16 on the surface of the support plate 2, and the upper surface of the guide plate 18 is at the same level as the round top end of the roller body of the positioning calendering roller 16 line, a water tank 19 is fixedly installed in the middle of the upper part of the surface of the base 1, and a booster pump 20 is fixedly installed at the lower left side of the surface of the left support plate 2, and the water suction port of the booster pump 20 is connected with the inside of the water tank 19 through a pipeline penetrating the support plate 2, and a drain pipe 21 is fixedly installed on the upper end of the booster pump 20, and two cross bars 22 are correspondingly arranged at the upper and lower ends of the rear of the opposite side of the support plate 2, and a nozzle 23 is fixedly arranged on the outer surface of the cross bar 22 facing the side, and a multi-way pipe 24 is installed inside the cross bar 22, and the multi-way pipe 24 is connected with the nozzle 23, and the left end of the multi-way pipe 24 penetrates the cross bar 22 and the left support plate 2 and is connected with the drain pipe 21.

[0024] Furthermore, the internal threaded hole block 14 slides and fits with the inner surface of the groove 10, and the guide block 13 slides and fits with the inner surface of the through cavity 11. When the screw 12 rotates, the internal threaded hole block 14 stably drives the movable calendering roller 15 to move up and down under the limitation of the groove 10 and the guide block 13, so that the distance between the movable calendering roller 15 and the positioning calendering roller 16 can be adjusted according to the thickness of different metal products.

[0025] Furthermore, the driving motor 17 drives the positioning calendering roller 16 to rotate, and then the lower pulley 8 is rotated, and the synchronous belt 9 is used to drive the upper pulley 8 to rotate, so that the movable calendering roller 15 rotates. Because the synchronous belt 9 is wound in an "∞" shape, the pulley 8 rotates in the opposite direction, and then the rotation directions of the movable calendering roller 15 and the positioning calendering roller 16 are opposite, so that the metal plate is transported and calendered in the same direction.

[0026] Furthermore, when the movable calendering roller 15 and the positioning calendering roller 16 are adjusting the spacing, since the pulley 8 is fixed to the movable calendering roller 15 and the positioning calendering roller 16, the position of the pulley 8 will also change, and the upper pulley 8 moves downward to loosen the synchronous belt 9. The thrust spring 5 is used to always maintain the backward driving force to push the movable arm 6 to move backward along the slide groove 4, thereby driving the tensioning wheel 7 to move backward, and then re-tightening the synchronous belt 9 to ensure the fit between the synchronous belt 9 and the upper and lower pulleys 8 to ensure a stable transmission effect.

[0027] Furthermore, the water inlet end of the booster pump 20 is connected to the inside of the water tank 19 through a pipe, and can absorb water in the water tank 19, and discharge it to the nozzle 23 through the drainage pipe 21 and the multi-way pipe 24, so as to evenly water the metal plate and the upper and lower surfaces of the calendering mechanism in the calendering process to cool it down.

[0028] Furthermore, the water tank 19 is arranged in the middle of the base 1. After being filled with water, the weight of the lower end of the entire device can be greatly increased, thereby also improving the overall stability of the device.

[0029] Working principle: When using the calendering device for metal products, first, place the metal piece to be calendered on the guide plate 18, and then rotate the screw 12 according to the calendering thickness of the metal piece. The internal threaded hole block 14 can drive the movable calendering roller 15 to move up and down under the limit of the groove 10, thereby changing the distance between the positioning calendering roller 16 and the positioning calendering roller 16. When the distance between the positioning calendering roller 16 and the movable calendering roller 15 is adjusted, the pulley 8 will follow the adjustment. When the upper pulley 8 moves downward, the synchronous belt 9 becomes loose. At this time, the thrust spring 5 will push the movable arm 6 to move backward along the slide groove 4, thereby driving the tensioning wheel 7 to move backward, and then re-tighten the synchronous belt 9. If the upper pulley 8 moves upward, the tensioning wheel 7 and the movable arm 6 are pulled to move forward through the pulling force of the synchronous belt 9. The thrust spring 5 is used to always maintain the backward driving force to ensure that the tensioning wheel 7 can make the synchronous belt 9 tightened no matter how the pulley 8 moves. The step belt 9 maintains effective transmission with the upper and lower side pulleys 8, and then the drive motor 17 is started. The drive motor 17 drives the positioning calendering roller 16 to rotate, and then the lower pulley 8 is rotated. The synchronous belt 9 is used to drive the upper pulley 8 to rotate, so that the movable calendering roller 15 rotates. Because the synchronous belt 9 is wound in an "∞" shape, the pulley 8 rotates in the opposite direction, and then the rotation directions of the movable calendering roller 15 and the positioning calendering roller 16 are opposite. The metal parts are then pushed between the movable calendering roller 15 and the positioning calendering roller 16 to carry out the same-direction conveying and calendering of the metal parts. During the calendering process, the booster pump 20 can suck water from the water tank 19 and input it into the drain pipe 21. With the continuous output of water pressure, the water will enter the multi-way pipe 24 and then be sprayed out through the nozzle 23 to evenly pour the metal plate and the upper and lower surfaces of the calendering mechanism during the calendering process to cool them down. This is the working principle of the calendering device for metal products.
