Description

Technical Field

[0001] This utility model relates to the technical field of cold rolling of carbon steel, and in particular to a cold rolling apparatus for carbon steel. Background Technology

[0002] Carbon steel is a metallic material primarily composed of iron and carbon. The carbon content directly affects its performance characteristics. Low-carbon steel has good plasticity and is easy to process, medium-carbon steel balances strength and toughness, while high-carbon steel is highly hard and wear-resistant. Due to its low cost, adjustable performance, and wide range of applications, carbon steel is widely used in construction, machinery manufacturing, the automotive industry, and everyday consumer goods, making it an indispensable basic material in modern industry.

[0003] Currently, traditional carbon steel cold rolling equipment generally adopts a single-pass rolling mode, that is, the material is subjected to pressure in one pass using only one set of cold rolling rolls to achieve thinning. Although this single-pass forming process is simple in structure, when faced with large reduction ratio requirements, it is prone to stress concentration inside the material due to excessive deformation in a single pass, resulting in significant work hardening. This not only increases the load on the equipment and roll wear, but may also affect the surface quality and final performance of the product, limiting its application potential in the production of high-precision and high-quality sheet metal. Utility Model Content

[0004] In view of the problems that the existing technology has caused by excessive deformation in a single process, resulting in severe material work hardening, high equipment load, and difficulty in balancing production efficiency and final product quality, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a carbon steel cold rolling device, which aims to solve the problem that the existing technology has serious material work hardening and high equipment load due to excessive single deformation, and it is difficult to balance production efficiency and final product quality.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a carbon steel cold rolling device, including a base frame, and further including a first adjusting mechanism, a second adjusting mechanism and a cold rolling mechanism, wherein the first adjusting mechanism includes a first sliding groove formed on both sides of the base frame, and a first sliding seat is slidably installed inside the first sliding groove; The second adjustment mechanism is provided in three sets. The second adjustment mechanism includes a second slide groove formed on the surface of the first slide seat, and a second slide seat is slidably installed on both sides of the interior of the second slide groove. The cold rolling mechanism includes a cold rolling roll rotatably mounted inside the second sliding seat, and a winding shaft rotatably mounted on the upper side of one side of the base frame.

[0007] In a preferred embodiment of the carbon steel cold rolling device of this utility model, a first motor is fixedly installed on one side of the first chute, a first screw is driven and installed at the output end of the first motor, and the first sliding seat is threadedly installed on the surface of the first screw.

[0008] In a preferred embodiment of the carbon steel cold rolling device of this utility model, a rolling wheel is rotatably mounted on the lower outer side of the first sliding seat, and the rolling wheel rolls on the upper part of the base.

[0009] In a preferred embodiment of the carbon steel cold rolling device of this utility model, a second motor is fixedly installed on the upper part of the second chute, a second screw is driven and installed at the output end of the second motor, and the second sliding seat is threadedly installed on the surface of the second screw.

[0010] In a preferred embodiment of the carbon steel cold rolling device of this utility model, the two sets of second adjusting mechanisms on both sides are slidably disposed on the upper surface of the base frame, and the middle set of second adjusting mechanisms is fixedly installed on the upper surface of the base frame.

[0011] In a preferred embodiment of the carbon steel cold rolling apparatus of this utility model, the spacing between the cold rolling rolls in each group is progressively decreasing on the inner side of the second sliding seat.

[0012] In a preferred embodiment of the carbon steel cold rolling device of this utility model, a fixing column is fixedly installed on one side of the upper surface of the base frame, a third motor is fixedly installed on the upper part of one side of the fixing column, and a first gear is driven at the output end of the third motor.

[0013] In a preferred embodiment of the carbon steel cold rolling apparatus of this utility model, a second gear is fixedly installed at one end of the winding shaft, and the second gear and the first gear mesh with each other.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model, through the setting of three sets of second-gap adjustment mechanisms, allows carbon steel to undergo a first cold rolling process by passing through two sets of cold rolling rolls when it passes inside the first set of second-gap adjustment mechanisms. After a period of cooling, it enters the second set of cold rolling rolls for cold rolling again, and then passes through the third set of cold rolling rolls for cold rolling. The spacing between the three sets of cold rolling rolls gradually decreases, thereby achieving the purpose of gradually extruding and cold rolling carbon steel. This effectively reduces the amount of reduction per pass, significantly reduces the work hardening of the material, and thus reduces the equipment load and energy consumption. At the same time, the step-by-step rolling combined with intermittent cooling ensures the uniformity of the internal structure and the flatness of the surface of the plate. Ultimately, while improving product quality, it also extends the service life of the equipment and rolls.

[0015] 2. This utility model, through the first adjustable spacing mechanism, drives the first screw to rotate via the first motor, which in turn drives the two sets of second adjustable spacing mechanisms on both sides to slide synchronously in opposite directions. This adjusts the spacing between the two sets of cold rolling rolls according to the different materials of the cold-rolled steel, thereby achieving cooling for different durations. This not only ensures that the material obtains the best cooling effect and avoids performance defects caused by insufficient or excessive cooling, but also significantly improves the equipment's adaptability to different processing requirements, thus ensuring the quality stability and process reliability of the final product.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0019] Reference Figures 1-2 The first embodiment of this utility model provides a carbon steel cold rolling device. This carbon steel cold rolling device includes a base frame 1, a first adjusting mechanism 2, a second adjusting mechanism 3, and a cold rolling mechanism 4. The first adjusting mechanism 2 includes a first sliding groove 201 opened on both sides of the base frame 1, and a first sliding seat 204 is slidably installed inside the first sliding groove 201.

[0020] A first motor 202 is fixedly installed on one side of the first slide groove 201. A first screw 203 is driven and installed at the output end of the first motor 202. A first sliding seat 204 is threadedly installed on the surface of the first screw 203.

[0021] A rolling wheel 205 is rotatably mounted on the lower outer side of the first sliding seat 204, and the rolling wheel 205 rolls on the upper part of the base.

[0022] During operation, the first motor 202 is started, and its output drives the first screw 203 to start rotating. Since the first sliding seat 204 and the first screw 203 are threadedly engaged, the rotation of the first screw 203 will drive the first sliding seat 204 to slide precisely in a straight line along the first slide groove 201. During this process, the rolling wheel 205 installed on the lower outer side of the first sliding seat 204 contacts and rolls with the upper surface of the base frame 1, providing stable support and guidance for the movement of the entire sliding seat and reducing frictional resistance. When it is necessary to adjust the overall layout of the subsequent cold rolling mechanism 4 or reserve space for plates of different widths, the operator controls the first motor 202 to rotate forward or reverse, so that the first sliding seat 204 can drive all the components installed on it to move synchronously to the left or right to the predetermined position, thereby realizing the rapid, synchronous and precise adjustment of the lateral position of the entire cold rolling unit on the base frame 1. Example 2

[0023] Reference Figure 1 , Figure 2 and Figure 4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the second adjusting mechanism 3 is provided in three sets. The second adjusting mechanism 3 includes a second sliding groove 301 opened on the surface of the first sliding seat 204. The second sliding seat 304 is slidably installed on both sides of the inner side of the second sliding groove 301. The cold rolling mechanism 4 includes a cold rolling roll 410 rotatably installed on the inner side of the second sliding seat 304. A winding shaft 406 is rotatably installed on the upper side of one side of the base frame 1.

[0024] A second motor 302 is fixedly installed on the upper part of the second slide groove 301. A second screw 303 is driven and installed at the output end of the second motor 302. A second sliding seat 304 is threadedly installed on the surface of the second screw 303.

[0025] Two sets of second adjustment mechanisms 3 on both sides are slidably mounted on the upper surface of the base frame 1, and one set of second adjustment mechanisms 3 in the middle is fixedly mounted on the upper surface of the base frame 1.

[0026] The spacing between each set of cold rolling rolls 410 inside the second sliding seat 304 is set in a progressively decreasing manner.

[0027] A fixing column 402 is fixedly installed on one side of the upper surface of the base frame 1. A third motor 403 is fixedly installed on the upper part of one side of the fixing column 402. A first gear 404 is installed at the output end of the third motor 403.

[0028] A second gear 405 is fixedly installed at one end of the winding shaft 406, and the second gear 405 meshes with the first gear 404.

[0029] During operation, the carbon steel to be rolled first enters the first set of second pitch adjustment mechanisms 3. The second motor 302 in this mechanism drives the second screw 303 to rotate, which in turn drives the second sliding seats 304 on both sides to slide synchronously in opposite directions in the second slide groove 301, thereby accurately setting the initial roll gap of the first set of cold rolling rolls 410 and completing the first cold rolling. Subsequently, the steel plate is naturally cooled during the conveying process and then enters the second set of second pitch adjustment mechanisms 3 fixedly installed on the base frame 1. Its roll gap is smaller than that of the first set, and it is pressed down for the second time. Finally, the steel plate enters the third set of second pitch adjustment mechanisms 3, whose position is controlled by the first pitch adjustment mechanism 2, to complete the third and final cold rolling with the smallest amount of pressing down. After the entire rolling process is completed, the third motor 403 is started. The first gear 404 at the output end meshes with the second gear 405 fixed at one end of the winding shaft 406, transmitting power to the winding shaft 406 and driving it to rotate, thereby smoothly and evenly winding the carbon steel plate formed by three consecutive cold rolling processes into a coil.

[0030] The remaining structure is the same as that in Example 1.

[0031] Based on embodiments 1-2, the working principle of this utility model is as follows: First, according to the material and process requirements of the carbon steel to be processed, the first motor 202 is started. Through the rotation of the first screw 203, the second pitch adjustment mechanisms 3 on both sides are driven to slide synchronously in opposite directions on the base frame 1, thereby precisely adjusting the spacing between the three sets of cold rolling mechanisms 4, thus reserving the optimal cooling time for the material after each rolling pass. Subsequently, for each set of cold rolling mechanisms 4, its independent second motor 302 drives the second screw 303, causing the second sliding seats 304 on both sides to move synchronously towards or away from each other, setting the spacing of each set of cold rolling rolls 410 to a state that gradually decreases from the inlet to the outlet. Once everything is ready, the carbon steel begins to enter the first set of cold rolling rolls 410, completing the first cold rolling with a relatively large reduction. Afterward, it undergoes natural cooling over a set conveying distance. Next, the material enters the second set of cold rolling rolls 410, undergoes a second flattening, and after cooling again, it finally enters the third set of cold rolling rolls 410 for the most refined third cold rolling, achieving gradual and uniform thinning. After the entire three-pass rolling process is completed, the third motor 403 is started, and the power is transmitted to the winding shaft 406 through the meshing of the first gear 404 and the second gear 405, driving it to rotate and flatten and tightly coil the final high-quality carbon steel sheet into a coil, completing the entire processing flow.
