Description

Technical Field

[0001] This utility model relates to the field of bar rolling technology, and in particular to a rolling mill suitable for multi-slab bar rolling. Background Technology

[0002] Rolling mills are important equipment in the field of metal processing used for rolling metal materials. They are widely used in the production processes of industries such as steel and non-ferrous metals. Their main function is to apply pressure to metal billets, causing them to undergo plastic deformation between the rolls, thereby achieving the required size and shape.

[0003] In the bar rolling process, traditional rolling mills can usually only adapt to the processing needs of a single billet shape. This leads to the need for frequent roll changes or complex equipment adjustments when facing production tasks with diverse billet shapes. This not only increases production costs but also significantly reduces production efficiency. In addition, the adjustment of the roll gap of traditional rolling mills mostly relies on manual operation. This method is not only cumbersome and time-consuming, but also makes it difficult to guarantee the accuracy of the adjustment. It is easy to cause bar quality defects due to unstable roll position, which affects the final quality of the product. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a rolling mill applicable to multi-section bars.

[0005] This utility model is achieved using the following technical solution: a rolling mill suitable for multi-slab bar stock, comprising a base, a first sliding groove support plate fixedly connected to the upper surface of the base, a mounting seat fixedly connected to the surface of the first sliding groove support plate, a first motor fixedly connected to the surface of the mounting seat, a first perforated roll fixedly connected to the output end of the first motor, a second sliding groove support plate rotatably connected to the surface of the first perforated roll, a limit groove formed on the surfaces of both the first and second sliding groove support plates, a sliding block slidably connected inside the limit groove, a right-angle frame fixedly connected to the surface of the sliding block, a second motor fixedly connected to the surface of the right-angle frame, a second perforated roll fixedly connected to the output end of the second motor, and an adjustment mechanism provided on the inner wall of the base;

[0006] The adjusting mechanism includes a drive motor, a worm gear fixedly connected to the output end of the drive motor, a worm wheel meshing with the surface of the worm gear, a screw fixedly connected to the surface of the worm wheel, a telescopic rod threadedly connected to the surface of the screw, an abutment block fixedly connected to the surface of the telescopic rod, and a rotating rod fixedly connected to the surface of the worm wheel.

[0007] Through the above technical solution, the surfaces of multi-hole roll one and multi-hole roll two are provided with multiple holes, which can meet the processing requirements of different billet shapes and bars, improve the applicability of the equipment, and enable the equipment to adapt to various production scenarios without frequent roll replacement. The distance between multi-hole roll one and multi-hole roll two can be flexibly adjusted through the distance adjustment mechanism, which is convenient for personnel to make quick adjustments according to actual processing needs, thereby improving production efficiency. The worm and worm wheel have a self-locking function, which can effectively ensure the stability of multi-hole roll two after it moves to the appropriate position, thus ensuring the stability of the rolling process and the rolling quality.

[0008] As a further improvement to the above solution, the drive motor is fixedly connected to the inner wall of the base.

[0009] As a further improvement to the above solution, the abutment block is fixedly connected to the surface of the right-angle frame.

[0010] The above technical solution enables the right-angle frame to move accurately in a straight line within the limiting slide groove, improving the accuracy of the position adjustment of the multi-hole roll 2, thereby ensuring that the distance between the multi-hole roll 1 and the multi-hole roll 2 meets the processing requirements during the rolling process.

[0011] As a further improvement to the above solution, the worm gear is rotatably connected to the inner wall of the base.

[0012] As a further improvement to the above solution, the rotating rod is rotatably connected to the inner wall of the base.

[0013] Through the above technical solution, the rotating connection of the rotating rod provides stable support for the worm gear, avoiding wobbling or deviation of the worm gear during rotation, and improving the stability and reliability of the adjusting mechanism.

[0014] As a further improvement to the above solution, two sliding blocks are provided, which are fixedly connected to both sides of the right-angle frame respectively.

[0015] As a further improvement to the above solution, the base has a feeding cavity inside.

[0016] As a further improvement to the above scheme, the feeding chamber is located below the multi-hole type roll one and the multi-hole type roll two.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model features multi-hole type roll one and multi-hole type roll two with various hole patterns on their surfaces, allowing for flexible selection based on the processing requirements of different billet shapes, thus improving the applicability of the equipment. In the pitch adjustment mechanism, a drive motor drives a worm gear to rotate, which meshes with a worm wheel, driving a screw to rotate. The screw is threadedly connected to a telescopic rod, and through a contact block, the right-angle frame moves linearly along a limiting slide groove, adjusting the position of multi-hole type roll two and achieving pitch adjustment with multi-hole type roll one. This avoids the tediousness and inaccuracy of traditional manual adjustment, significantly shortening equipment adjustment time and improving production efficiency. The self-locking function of the worm gear and worm wheel ensures that multi-hole type roll two is stable and reliable after adjustment, preventing quality defects in the billet caused by unstable roll position and guaranteeing the stability and quality of the rolling process.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-4This embodiment of a rolling mill applicable to multi-slab bar stock includes a base 1. A slide support plate 2 is fixedly connected to the upper surface of the base 1. A mounting base 3 is fixedly connected to the surface of the slide support plate 2. A motor 4 is fixedly connected to the surface of the mounting base 3. A perforated roll 5 is fixedly connected to the output end of the motor 4. A slide support plate 6 is rotatably connected to the surface of the perforated roll 5. Limiting slide grooves 7 are provided on the surfaces of both the slide support plate 2 and the slide support plate 6. A sliding block 8 is slidably connected inside the limiting slide groove 7. A right-angle frame 9 is fixedly connected to the surface of the sliding block 8. A motor 10 is fixedly connected to the surface of the right-angle frame 9. A perforated roll 11 is fixedly connected to the output end of the motor 10. An adjusting mechanism 12 is provided on the inner wall of the base 1.

[0028] The adjusting mechanism 12 includes a drive motor 121. A worm gear 122 is fixedly connected to the output end of the drive motor 121. A worm wheel 123 is meshed with the surface of the worm gear 122. A screw 124 is fixedly connected to the surface of the worm wheel 123. A telescopic rod 125 is threadedly connected to the surface of the screw 124. A contact block 126 is fixedly connected to the surface of the telescopic rod 125. A rotating rod 127 is fixedly connected to the surface of the worm wheel 123. Motor 121 drives the multi-hole roller 5 to rotate, while the multi-hole roller 11 is driven by motor 10. The drive motor 121 in the adjusting mechanism 12 drives... The worm 122 rotates and meshes with the worm wheel 123. The worm wheel 123 drives the screw 124 to rotate. The screw 124 is threadedly connected to the telescopic rod 125, which in turn drives the contact block 126 to move. The contact block 126 pushes the right-angle frame 9 to move linearly along the limiting slide groove 7, thereby adjusting the position of the multi-hole type roll 11 and realizing the adjustment of the distance between the multi-hole type roll 11 and the multi-hole type roll 5. The surfaces of the multi-hole type roll 5 and the multi-hole type roll 11 are provided with multiple hole patterns. The appropriate hole pattern can be selected according to the actual processing requirements to process bars of different billet shapes.

[0029] The drive motor 121 is fixedly connected to the inner wall of the base 1. When it is necessary to adjust the position of the multi-hole type roll 11, the drive motor 121 starts, drives the worm gear 122 to rotate, and then through the transmission of the worm wheel 123 and the screw 124, the telescopic rod 125 and the contact block 126 are moved, pushing the right-angle frame 9 to perform a limited linear movement along the limiting slide groove 7, and finally adjusting the position of the multi-hole type roll 11.

[0030] The contact block 126 is fixedly connected to the surface of the right-angle frame 9. When the telescopic rod 125 in the adjusting mechanism 12 moves, the contact block 126 will move accordingly and transmit the force to the right-angle frame 9, pushing the right-angle frame 9 to perform a limiting linear movement along the limiting slide groove 7, thereby driving the multi-hole type roll 11 to move, so as to realize the adjustment of the distance between the multi-hole type roll 11 and the multi-hole type roll 5.

[0031] The worm gear 122 is rotatably connected to the inner wall of the base 1.

[0032] The rotating rod 127 is rotatably connected to the inner wall of the base 1. When the worm gear 123 rotates, the rotating rod 127 can rotate stably, playing the role of auxiliary support and transmission, and ensuring the stable connection between the worm gear 123 and the screw 124.

[0033] There are two sliding blocks 8, which are fixedly connected to both sides of the right-angle bracket 9.

[0034] The base 1 has a feeding chamber 13 inside.

[0035] The feeding chamber 13 is located below the multi-hole type roll 5 and the multi-hole type roll 11.

[0036] The implementation principle of a rolling mill applicable to multi-slab bar stock in this application embodiment is as follows: First, the operator needs to select a suitable pass shape according to the actual processing requirements. Multiple passes are opened on the surfaces of multi-slab roll 1 (5) and multi-slab roll 2 (11). The operator selects the pass shape that matches the bar stock to be processed for rolling. Then, the operator starts the drive motor 121, which is fixedly connected to the inner wall of the base 1, providing stable power. The output end of the drive motor 121 drives the worm gear 122 to rotate. The worm gear 122 is rotatably connected to the inner wall of the base 1, ensuring smooth rotation. The worm gear 122 meshes with the worm wheel 123, causing the worm wheel 123 to rotate. A screw 124 is fixedly connected to the surface of the worm wheel 123, causing the screw 124 to rotate. The screw 124 is threadedly connected to the telescopic rod 125, causing the telescopic rod 125 to move under the rotation of the screw 124. A contact block 126 is fixedly connected to the surface of the telescopic rod 125, which is fixedly connected to the surface of the right-angle frame 9. When the telescopic rod... When 125 moves, the abutment block 126 moves accordingly, transmitting force to the right-angle frame 9, pushing the right-angle frame 9 to perform a limited linear movement along the limiting slide groove 7. Two sliding blocks 8 are provided, fixedly connected to both sides of the right-angle frame 9. The two sliding blocks 8 slide synchronously within the limiting slide groove 7, serving to limit and guide the movement, ensuring smooth and linear motion of the right-angle frame 9. A second motor 10 is fixedly connected to the surface of the right-angle frame 9, and the output end of the second motor 10 is fixedly connected to a multi-hole rolling mill. The movement of the right-angle frame 9 drives the movement of the perforated roll 11, thereby adjusting the distance between the perforated roll 11 and the perforated roll 5. During the rolling process, the motor 4 drives the perforated roll 5 to rotate, and the motor 10 drives the perforated roll 11 to rotate. The rolled bar is discharged from the interior of the base 1 through the discharge chamber 13 opened inside the base 1. The discharge chamber 13 is located below the perforated roll 5 and the perforated roll 11, which facilitates the collection and subsequent processing of the bar.
