Description

Technical Field

[0001] This utility model relates to a oscillating three-roll forming machine. Background Technology

[0002] Currently, because the temperature of sheet and plate products extruded from extruder dies is very high, the products need to be fed into a three-roll forming mill for cooling and shaping after extrusion. When the product comes into contact with the rollers in the three-roll forming mill, the heat of the product is transferred to the rollers, thereby reducing the temperature of the product and allowing it to cool and solidify. For example, Chinese patent CN217993239U discloses a three-roll forming device for a multi-material co-extrusion sheet production line.

[0003] In actual production, it has been found that to improve the dimensional accuracy and flatness of products and prevent subsequent deformation, it is necessary to strictly control the contact time of the product on the rollers to achieve a better cooling and forming effect. Furthermore, the required contact time varies depending on the product thickness; generally, thicker products require a longer contact time, while thinner products require a shorter contact time. However, existing three-roll forming machines cannot adjust the contact time of the product on the rollers. Therefore, when producing products with significant thickness differences, different three-roll forming machines must be used, which is very cumbersome. For example, a skewed three-roll forming machine is better for thicker products, while a flat three-roll forming machine is better for thinner products, because the contact time between the product and the rollers differs between the two machines.

When producing thinner products, firstly, the feed channel and the discharge channel are reduced, and then the swing angle of the swing frame is adjusted to change the position of the third roller relative to the first roller, thereby shortening the contact time of the product on the three rollers. Therefore, it can adapt to the cooling and forming of products of different thicknesses, and there is no need to change the three-roll forming machine when producing products of different thicknesses, making it more convenient to use. In addition, by adjusting the contact time of the product on the three rollers, the cooling and forming effect of the product can also be improved, which is conducive to improving the forming quality of the product and increasing the product qualification rate.

[0058] The first roller 3 is rotatably connected to the frame 1;

[0059] The swing frame 2 is oscillatingly connected to the machine frame 1 with the central axis of the first roller 3 as the swing axis;

[0060] The first sliding mechanism is slidably connected to the frame 1;

[0061] The second sliding mechanism is slidably connected to the swing frame 2;

[0062] The second roller 4 is rotatably connected to the first sliding mechanism, and a feeding channel for the product 100 to pass through is provided between the second roller 4 and the first roller 3.

[0063] The third roller 5 is rotatably connected to the second sliding mechanism, and a discharge channel for the product 100 to pass through is provided between the third roller 5 and the first roller 3.

[0064] The first adjustment mechanism is connected to the frame 1. The first adjustment mechanism is connected to the first sliding mechanism and is used to drive the first sliding mechanism to move toward or away from the first roller 3, thereby driving the second roller 4 to move toward or away from the first roller 3, so as to adjust the size of the feed channel.

The second adjustment mechanism is connected to the second sliding mechanism and is used to drive the second sliding mechanism to move toward or away from the first roller 3, thereby driving the third roller 5 to move toward or away from the first roller 3, so as to adjust the size of the discharge channel.

[0066] The swing drive mechanism is mounted on the frame 1. The swing drive mechanism is connected to the swing frame 2 and is used to drive the swing frame 2 to swing, thereby driving the third roller 5 to swing around the first roller 3.

[0067] Specifically, after the product 100 is extruded from the mold, it first passes through the feeding channel and wraps around the first roller 3, then passes through the discharge channel and wraps around the third roller 5. During this process, each part of the product 100 will be in contact with the first roller 3, the second roller 4, and the third roller 5 for a period of time. During this contact time, the temperature of the product 100 will be transferred to the three rollers. The time elapsed from the initial contact with the first roller 3 and the second roller 4 to the separation from the third roller 5 is the contact and dwell time of the product 100 on the three rollers. In this embodiment, the swing drive mechanism can drive the swing frame 2 to swing, thereby causing the third roller 5 to swing around the first roller 3. Therefore, by adjusting the swing angle of the swing frame 2, the position of the third roller relative to the first roller 3 can be adjusted, thereby adjusting the contact and dwell time of the product 100 on the three rollers. Figures 7-9As shown, since the moving speed of the product 100 is constant, the longer the contact length between the product 100 and the three rollers, the longer the product 100 stays in contact with the three rollers. When producing a thicker product 100, firstly, the feed channel and the discharge channel are enlarged, and then the swing angle of the swing frame 2 is adjusted to change the position of the third roller relative to the first roller 3, thereby increasing the contact time of the product 100 on the three rollers. When producing a thinner product 100, firstly, the feed channel and the discharge channel are reduced, and then the swing angle of the swing frame 2 is adjusted to change the position of the third roller relative to the first roller 3, thereby shortening the contact time of the product 100 on the three rollers. Therefore, it can adapt to the cooling and forming of products 100 of different thicknesses, and there is no need to change the three-roll forming machine when producing products 100 of different thicknesses, making it more convenient to use. Furthermore, by adjusting the duration of contact and residence of the product 100 on the three rollers, the cooling and molding effect of the product 100 can be improved, which in turn helps to improve the molding quality of the product 100 and increase the pass rate of the product 100.

[0102] In summary, after the product 100 is extruded from the mold, it first passes through the feeding channel and wraps around the first roller 3, then passes through the discharge channel and wraps around the third roller 5. During this process, each part of the product 100 will be in contact with the first roller 3, the second roller 4, and the third roller 5 for a period of time. During this contact time, the temperature of the product 100 will be transferred to the three rollers. The time elapsed from the initial contact with the first roller 3 and the second roller 4 to the separation from the third roller 5 is the contact and dwell time of the product 100 on the three rollers. The swing drive mechanism can drive the swing frame 2 to swing, thereby causing the third roller 5 to swing around the first roller 3. Therefore, by adjusting the swing angle of the swing frame 2, the position of the third roller relative to the first roller 3 can be adjusted, thus adjusting the contact and dwell time of the product 100 on the three rollers. Figures 7-9As shown, since the moving speed of the product 100 is constant, the longer the contact length between the product 100 and the three rollers, the longer the product 100 stays in contact with the three rollers. When producing a thicker product 100, firstly, the feed channel and the discharge channel are enlarged, and then the swing angle of the swing frame 2 is adjusted to change the position of the third roller relative to the first roller 3, thereby increasing the contact time of the product 100 on the three rollers. When producing a thinner product 100, firstly, the feed channel and the discharge channel are reduced, and then the swing angle of the swing frame 2 is adjusted to change the position of the third roller relative to the first roller 3, thereby shortening the contact time of the product 100 on the three rollers. Therefore, it can adapt to the cooling and forming of products 100 of different thicknesses, and there is no need to change the three-roll forming machine when producing products 100 of different thicknesses, making it more convenient to use. Furthermore, by adjusting the duration of contact and residence of the product 100 on the three rollers, the cooling and molding effect of the product 100 can be improved, which in turn helps to improve the molding quality of the product 100 and increase the pass rate of the product 100.
