Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, and in particular to a roller combination structure that can roll multiple steel strips at once. Background Technology

[0002] A rolling machine is a mechanical device used to roll metal sheets or other plastic materials into round or arc-shaped workpieces.

[0003] Existing rolling machines typically use grooves of different sizes on the surface of the rolling rollers. Changing the rolling rollers allows for the rolling of steel bars with different cross-sections, but only one steel bar can be rolled at a time. This results in low rolling efficiency, failing to meet the processing rhythm of subsequent steps. Furthermore, the size of the grooves is fixed after the equipment is manufactured, while diverse market demands have led to the production of many non-standard sized steel bars. These steel bars with special widths often cannot be precisely matched to the predetermined groove sizes on the rolling rollers. If the width of the steel bar does not match the groove, it is prone to displacement, shaking, or even detachment from the groove during the rolling process. This not only interferes with the normal rolling process but also potentially leads to deviations in the shape accuracy of the rolled steel bar, surface scratches, and other problems, ultimately negatively impacting the rolling effect. This application provides a rolling roller combination structure that can roll multiple steel bars at once to meet this requirement. Summary of the Invention

[0004] This utility model provides a roller combination structure that can roll multiple steel strips at once, in order to solve the problems of existing rolling machines that can only roll one steel strip at a time, resulting in low rolling efficiency, which cannot meet the cycle time of subsequent processing, and the fixed size of the groove, which makes it difficult to adapt to steel strips of different widths.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A roller assembly structure capable of rolling multiple steel strips at once is disclosed. The roller assembly structure includes a rolling machine, wherein a drive roller is sleeved on the main shaft of the rolling machine, and a driven roller is rotatably connected to one side of the rolling machine; and an adjustment component for synchronously adjusting the distance between fixed dies, the adjustment component being connected to the driven roller.

[0007] Optionally, the adjusting assembly includes an adjusting threaded rod, one end of which is rotatably connected to the inside of the driven roller, and a handwheel is fixedly connected to the end of the adjusting threaded rod away from the driven roller. An adjusting rod is threadedly connected to the surface of the adjusting threaded rod.

[0008] Optionally, the surface of the adjusting threaded rod is provided with multiple bidirectional threads, and the adjusting rods are symmetrically screwed onto the bidirectional threaded surface in groups of two.

[0009] Optionally, the driven roller has slots and guide grooves extending from its interior to its surface, and the guide grooves are "L"-shaped.

[0010] Optionally, the inner contours of the slot and the guide groove both match the outer contour of the adjusting rod, and the adjusting rod is slidably connected inside the guide groove.

[0011] Optionally, the adjusting rod has a fixing groove inside, and a fixing mold is engaged inside the fixing groove.

[0012] Optionally, a fixing rod is fixedly connected inside the fixing mold, and the inner contour of the fixing groove matches the outer contour of the fixing rod.

[0013] Optionally, a weakening groove is provided at the end of the fixing groove away from the fixing rod.

[0014] Optionally, a graduated groove is provided on the surface of the driven roller at a position corresponding to the fixed mold.

[0015] Optionally, a pressure roller is sleeved on the surface of the drive roller, and the surface of the pressure roller is provided with protrusions.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above scheme, by setting up an adjustment component, rotating the handwheel drives the adjustment threaded rod to rotate. Utilizing a bidirectional thread design, the adjustment rods can move in opposite directions, allowing for precise adjustment based on the actual width of the steel strip. This adapts to steel strips of different specifications, expanding the equipment's applicability. The adjustment threaded rod surface has multiple bidirectional threads, with an adjustment rod screwed onto each set of threads. When adjusting the spacing of one set of adjustment rods, the spacing of all adjustment rods can be adjusted synchronously. Because multiple sets of adjustment rods are set, placing the steel strip inside the adjustment rods during rolling allows for the simultaneous rolling of multiple steel strips, improving the production efficiency of the rolling operation.

[0018] By setting an adjusting rod and its internal fixing groove, when different shapes of steel bars (such as channel steel) need to be rolled, the fixing rod can be moved along the weakening groove and separated from the adjusting rod by moving the fixing mold. This allows for convenient replacement of the fixing mold without complicated tools and processes, and adapts to diverse production needs. Attached Figure Description

[0033] like Figures 1 to 5As shown, an embodiment of this utility model provides a rolling mill assembly structure capable of rolling multiple steel strips at once. It includes a rolling mill 1, with a drive roller 2 sleeved on the main shaft of the rolling mill 1. The main shaft of the rolling mill 1 uses a universal joint, and the drive roller 2 is rotated by a motor through a reducer, simultaneously allowing for vertical adjustment of the drive roller 2. This is existing technology, which can press the steel strip during rolling and lift the drive roller 2 for easy removal of the steel strip after rolling. A driven roller 3 is rotatably connected to one side of the rolling mill 1, located below the drive roller 2, assisting the drive roller 2 in rolling the steel strip. The end of the driven roller 3 furthest from the rolling mill 1 is rotatably connected inside a fixed platform, which is existing technology and can be... Open; Adjustment component, the adjustment component is used to synchronously adjust the distance between the fixed molds 6. The adjustment component is connected to the driven roller 3. By setting the adjustment component, turning the handwheel 401 drives the adjustment threaded rod 4 to rotate. Utilizing the bidirectional thread design, the two adjustment rods 5 screwed onto the bidirectional thread surface can move in opposite directions. It can be precisely adjusted according to the actual width of the steel strip and can adapt to steel strips of different specifications. At the same time, the surface of the adjustment threaded rod 4 has multiple bidirectional threads, and each set of threads is screwed onto a set of adjustment rods 5. When adjusting the spacing of a set of adjustment rods 5, the spacing of all adjustment rods 5 can be adjusted synchronously, thereby realizing the simultaneous rolling of multiple steel strips and improving the production efficiency of the rolling operation.

[0034] like Figures 2 to 4 As shown, the adjusting assembly includes an adjusting threaded rod 4. One end of the adjusting threaded rod 4 is rotatably connected to the inside of the driven roller 3. The connection method is existing technology and will not be described in detail here. A handwheel 401 is fixedly connected to the end of the adjusting threaded rod 4 away from the driven roller 3. An adjusting rod 5 is threadedly connected to the surface of the adjusting threaded rod 4. The surface of the adjusting threaded rod 4 has multiple bidirectional threads, with adjacent threads having opposite directions. The adjusting rods 5 are symmetrically screwed onto the bidirectional threaded surface in pairs. Rotating the handwheel 401 rotates the adjusting threaded rod 4, thereby adjusting the two adjusting rods in a group. 5. The rollers move in opposite directions, allowing for precise adjustment based on the width of the steel strip, thus improving their applicability. Each section of the bidirectional threaded surface is screwed with an adjusting rod 5, enabling simultaneous adjustment of the distance between all adjusting rods 5 while adjusting the distance between a group of adjusting rods 5. This allows for the simultaneous rolling of multiple steel strips. The roller 3 extends from its interior to its surface and has a slot 301 and a guide groove 302. The guide groove 302 is L-shaped, and the inner contours of the slot 301 and the guide groove 302 match the outer contour of the adjusting rod 5. The adjusting rod 5 is slidably connected inside the guide groove 302.

[0035] like Figure 5As shown, the adjusting rod 5 has a fixing groove 501 inside, and a fixing mold 6 is engaged inside the fixing groove 501. The inner contour of the fixing mold 6 can be changed according to the shape of the rolled steel strip. A fixing rod 601 is fixedly connected inside the fixing mold 6, and the inner contour of the fixing groove 501 matches the outer contour of the fixing rod 601. A weakening groove is provided on the side of the fixing groove 501 away from the fixing rod 601. When the fixing mold 6 needs to be replaced, the fixing platform near the handwheel 401 of the rolling machine 1 can be opened, and the fixing mold 6 can be moved inward. The fixing rod 601 will then follow the weakening groove, disengage from the fixing groove 501, and separate from the adjusting rod 5. Then, the fixing mold 6 can be pushed to the end of the guide groove 302, and the fixing mold 6 can be rotated to slide into the slot 301. The old fixing mold can then be pulled out along the slot 301. Then, according to the shape of the steel strip to be rolled, the new fixed mold 6 is moved along the slot 301 into the guide groove 302 and re-inserted into the fixed groove 501 to complete the fixing. The driven roller 3 has a scale groove 8 at the corresponding position of the fixed mold 6, which can measure the width of the rolled steel strip. The surface of the driving roller 2 is fitted with a pressure roller 7. The surface of the pressure roller 7 is provided with protrusions. During rolling, the pressure roller 7 can be pressed down to press the steel strip and prevent the steel strip from bouncing.

[0036] The workflow of the technical solution provided by this utility model is as follows:

[0037] Before rolling, place the steel strip to be rolled between the driven roller 3 and the driving roller 2. Turn the handwheel 401 to rotate the adjusting threaded rod 4. Because the adjusting threaded rod 4 has a bidirectional thread, the adjusting rod 5 connected to it will move in opposite directions, thereby driving the fixed mold 6 to clamp and fix the steel strip. The adjusting threaded rod 4 has multiple bidirectional threads on its surface, and each set of threads is connected to the adjusting rod 5. Therefore, when adjusting the spacing of a set of fixed molds 6, the distance between all fixed molds 6 can be adjusted synchronously. After completing this step, continue to place the steel strip between the fixed molds 6. Once it is properly placed, the rolling machine 1 can be started. At this time, the rolling machine 1 can press down the driving roller 2, so that the pressing roller 7 tightly presses down on the steel strip to prevent the steel strip from bouncing up during the rolling process. After the steel strip is pressed down, the rolling machine 1 can drive the driving roller 2 to rotate and perform the rolling operation on the steel strip. After the rolling is completed, the rolled blank can be taken out by lifting the driving roller by the rolling machine 1. If a change of shape is required to roll channel steel with different cross-sections, the fixed platform near the handwheel 401 of the rolling machine 1 can be opened, and the fixed mold 6 can be moved inward. The fixed rod 601 will then move along the weakening groove, disengage from the fixed groove 501, and separate from the adjusting rod 5. Then, continue to push the fixed mold 6 to move it to the end of the guide groove 302, rotate the fixed mold 6 to make it slide into the slot 301, and pull out the old fixed mold 6 along the slot 301. Then, according to the shape of the steel strip to be rolled, move the new fixed mold 6 along the slot 301 into the guide groove 302, and re-lock it into the fixed groove 501 to complete the fixing.
