Description

Technical Field

[0001] The utility model relates to the technical field of steel plate processing, in particular to a steel plate flattening machine with high flattening efficiency. Background Art

[0002] For the convenience of storage and transportation, factories often roll steel plates into coils, and then unroll the coils again after transporting them to the next production workshop. However, the processing problems that steel plates often encounter after unrolling are: in the actual steel plate processing environment, processing techniques such as cutting and stamping often have certain requirements for the flatness of the steel plates. However, the surface of thin steel plates has been deformed and bent due to being placed in coils before processing, so the processing accuracy is prone to low. Therefore, a steel plate flattening machine is needed to improve this problem.

[0003] Chinese utility model patent application number 201420506467.9 discloses a multi-purpose, high-efficiency steel plate flattening machine, comprising a frame and a flattening mechanism, the flattening mechanism comprising an upper pressing wheel, a lower pressing wheel, a roller, and a limiting mechanism. The upper and lower pressing wheels are shaft-connected to the frame, and there are three upper and lower pressing wheels, each arranged side by side on the frame. Sprockets are provided on both sides of the pressing wheel and the lower pressing wheel and connected by a chain. The roller shaft is connected to the frame. The limiting mechanism comprises a limiting baffle, and the side of the limiting baffle is provided with two hydraulic rods and seven holes. The hydraulic rods are located at the same height and are connected to a hydraulic motor. The upper and lower pressing wheels and the roller can all pass through the limiting baffle through the holes. Although the steel plate flattening machine of this patent can flatten steel plates, when the steel plate passes through a pair of upper and lower pressing wheels, the upper and lower pressing wheels only perform a single pressing of the steel plate, resulting in low processing efficiency and high energy consumption.

DETAILED DESCRIPTION

[0018] In order to facilitate the understanding of those skilled in the art, the following embodiments and accompanying drawings are provided. Figure 1-2 To further illustrate the present invention, the contents mentioned in the implementation manner are not intended to limit the present invention.

[0019] See Figure 1-2 A steel plate flattening machine with high flattening efficiency includes a base 1, a support frame 2 fixed to one side of the top of the base 1, a flattening mechanism 3 installed on the support frame 2 and used to flatten the steel plate, the flattening mechanism 3 includes N upper pressing wheels 31 installed side by side on the support frame 2, N+1 lower pressing wheels 32 installed side by side below the upper pressing wheels 31, a driving mechanism 4 for driving one of the lower pressing wheels 32 to rotate, and an adjusting mechanism 5 for adjusting the gap between the upper pressing wheels 31 and the lower pressing wheels 32. The N upper pressing wheels 31 and the N+1 lower pressing wheels 32 are arranged in an alternating pattern up and down, and N is a positive integer between 2 and 8. In this example, the support frame 2 includes two mounting plates 22 fixed in parallel and at intervals to the top 1 of the base, and the ends of the upper pressing wheels 31 and the lower pressing wheels 32 are respectively mounted on the two mounting plates.

[0020] The steel plate flattening machine of the present invention arranges the upper pressing wheel 31 and the lower pressing wheel 32 in an alternating manner, so that each time the steel plate passes through the upper pressing wheel 31 or the lower pressing wheel 32, the pressing wheel will flatten the steel plate once. This can reduce processing time, improve flattening efficiency, reduce energy consumption, shorten the flattening distance, reduce equipment size, and has a simple structure and is easy to use.

[0021] In this example, the driving mechanism 4 includes a motor 41, a transmission belt 42 installed at the output end of the motor 41, a reduction gear box 43 connected to the transmission belt 42, and a coupling 44 fixed to the output end of the reduction gear box 43, the other end of the coupling 44 is fixedly connected to the axle at one end of one of the lower pressure wheels 32. Specifically, the output end of the motor 41 is fixed with a driving wheel, the input end of the reduction gear box 43 is fixed with a driven wheel, the transmission belt 42 is connected between the driving wheel and the driven wheel, the motor 41 drives the reduction gear box 43 to operate through the transmission belt 42, the output end of the reduction gear box 43 is fixedly connected to the axle on one side of one of the lower pressure wheels 32 through the coupling 44, and then drives the rotation of the lower pressure wheel 32. After the steel plate is placed in the gap between the upper pressure wheel 31 and the lower pressure wheel 32, it moves forward under the action of the lower pressure wheel 32, and the upper pressure wheel 31 and the lower pressure wheel 32 flatten the steel plate.

[0022] In this example, the support frame 2 is provided with mounting holes (not shown) at the positions corresponding to the two ends of each of the lower pressing wheels 32, and the wheel axles at the two ends of each lower pressing wheel 32 are respectively rotatably connected to the corresponding mounting holes. The provision of the mounting holes facilitates the rotation of the lower pressing wheel 32 and can prevent the lower pressing wheel 32 from shifting during the rotation process. In addition, the connection between the mounting hole wall and the lower pressing wheel 32 can be fully coated with lubricating oil to reduce the resistance of the lower pressing wheel 32 during rotation and reduce energy consumption.

[0023] In this example, the support frame 2 is longitudinally provided with adjustment holes 21 at positions corresponding to both ends of each upper pressing wheel 31. The adjustment mechanism 5 includes a sliding seat 52 slidably connected to each adjustment hole 21. The wheel axles at both ends of each upper pressing wheel 31 are rotatably connected to the corresponding sliding seat 52. The sliding seat 52 can slide up and down in the adjustment hole 21, thereby adjusting the distance between the upper pressing wheel 31 and the lower pressing wheel 32.

[0024] In this example, the support frame 2 has a threaded hole (not shown) longitudinally opened at the top of each adjustment hole 21, which is connected to the top of the adjustment hole 21. The adjustment mechanism 5 also includes an adjustment screw 51 screwed into the threaded hole. The bottom of the adjustment screw 51 passes through the threaded hole and is fixedly connected to the top of the sliding seat 52. By rotating the adjustment screw 51, the sliding seat 52 is driven to move up and down, and the distance between the upper pressure wheel 31 and the lower pressure wheel 32 can be adjusted.

[0025] In this embodiment, the adjustment mechanism 5 further includes a fastening nut 53 screwed onto the middle portion of the adjusting screw 51, with the bottom of the fastening nut 53 abutting against the top of the support frame 2. When the spacing between the upper pressing wheel 31 and the lower pressing wheel 32 is adjusted to a suitable spacing for pressing the steel plate, the fastening nut 53 is adjusted to the corresponding position of the adjusting screw 51 to secure the adjusting screw 51, thereby preventing the sliding seat 52 from moving during the pressing process and maintaining the spacing between the upper pressing wheel 31 and the lower pressing plate 32 unchanged.

[0026] In this embodiment, the top of the adjusting screw 51 extends out of the top of the threaded hole and is fixed with an adjusting dial 54. Turning the adjusting dial 54 clockwise or counterclockwise can move the adjusting screw 51 up and down, thereby driving the sliding seat 52 to move up and down, and further adjusting the distance between the upper pressing wheel 31 and the lower pressing wheel 32.

[0027] In this embodiment, the cross-section of the upper portion of the sliding seat 52 is square, which can reduce the lateral movement of the upper pressure wheel 31, and the cross-section of the lower portion of the sliding seat 52 is semicircular, which facilitates the sliding of the sliding seat 52 in the adjustment hole 21. In other embodiments, the cross-section of the upper portion of the sliding seat 52 and the cross-section of the lower portion of the sliding seat 52 can be any geometric shape, and the sliding seat 52 can be configured as needed.

[0028] In this example, there are two upper pressing wheels 31 and three lower pressing wheels 32. In this example, by driving the middle lower pressing wheel 32 to rotate, the steel plate can be moved from one end of the equipment to the other end. In other embodiments, the number of upper pressing wheels 31 can be three or more, and the number of lower pressing wheels 32 can be four or more. The number of upper pressing wheels 31 and lower pressing wheels 32 can be set as needed.

[0029] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the scope of protection of the present invention.
