Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a metal rolling and pushing device. Background Technology

[0002] Metal rolling is one of the important processes for plastic forming of metal materials, and it is widely used in automobile manufacturing, aerospace, building decoration and other fields. In the metal rolling process, the metal sheet to be processed needs to be accurately and steadily pushed between the rolls of the rolling equipment by a pushing device to ensure the dimensional accuracy and surface quality of the rolled material.

[0003] A search revealed a metal rolling and pushing device disclosed in Chinese Patent No. CN223250226U. The device uses a worktable to support a metal sheet, a pushing mechanism to move the sheet, and a guide structure to laterally limit the sheet to prevent it from shifting during the pushing process.

[0004] However, in existing technologies, for thin or long metal sheets, the sheet itself is not rigid enough during the pushing process, and warping is easily caused by uneven pushing force or differences in friction on the worktable surface. This leads to interference between the sheet and the pushing device or rolling equipment, affecting the pushing accuracy and rolling quality. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] In view of the above-mentioned background technology, there are shortcomings and defects in the existing technology, such as the easy warping of the board material.

[0006] The metal rolling and pushing device disclosed in this utility model includes a worktable, on which two fixed plates are symmetrically arranged at the upper end. A pushing component is installed on the worktable between the fixed plates. A push plate is provided on the side of the two fixed plates that are close to each other. The push plates are connected to the fixed plates by an electric telescopic rod. An anti-warping component is provided between the two push plates. Multiple anti-warping components are provided.

[0007] Furthermore, the plurality of anti-warping components are evenly distributed, and at least two anti-warping components are provided.

[0008] Furthermore, the anti-tilting component includes two sliding plates, which are mounted on corresponding push plates. A lifting plate is provided at the lower end of the side of the two sliding plates that are close to each other. A universal wheel is rotatably mounted at the lower end of the lifting plate. A guide rail is mounted on the sliding plate. The lifting plate is slidably disposed with the guide rail. A lifting component is provided between the lifting plate and the sliding plate.

[0009] Furthermore, the lifting component includes a screw, one end of which is mounted on the lifting plate. A threaded cylinder is rotatably mounted on the sliding plate and is threadedly connected to the screw. A worm gear is mounted on the threaded cylinder, and a worm is meshed on one side of the worm gear. The worm is rotatably mounted on the lifting plate, and the worms on the same side are connected by a transmission rod. One end of the transmission rod is provided with a drive source, and the drive source is mounted on the corresponding sliding plate.

[0010] Furthermore, a vertical cylinder is provided above the screw, the upper end of the vertical cylinder is fixedly connected to the lifting plate, the lower end of the vertical cylinder is sleeved on the screw, and the screw and the vertical cylinder are slidably disposed.

[0011] Furthermore, a guide rod is provided above the anti-tilting component, and both ends of the guide rod are fixedly mounted on the corresponding fixed plate by mounting plates. The guide rod is slidably disposed with the slide plate.

[0012] Furthermore, the pushing component includes a push block, which is slidably mounted on the worktable. A lead screw is rotatably mounted on the lower end of the worktable. The lead screw is threadedly connected to the push block. A stepper motor is mounted on one end of the lead screw, and the stepper motor is mounted on the worktable.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting multiple evenly distributed anti-warping components between two push plates, can assist in limiting the plate at multiple key positions along the plate's pushing path; in conjunction with the lifting components, the height of the lifting plates and casters can be flexibly adjusted to adapt to metal plates of different thicknesses, ensuring that the casters always fit in contact with the plate surface. This not only prevents the plate from warping due to insufficient rigidity, but also prevents the plate from being pushed through the rolling characteristics of the casters, thus preventing interference between the plate and the device or rolling equipment, ensuring the stability of the pushing process and the dimensional accuracy and surface quality of the rolling process.

[0015] 2. The pushing component of this utility model adopts a structure of lead screw and stepper motor, which can drive the push block to accurately move the plate and ensure the accuracy of the plate pushing position. The push plate between the two fixed plates is connected by an electric telescopic rod, which can flexibly adjust the spacing according to the width of the metal plate to achieve lateral limiting of plates of different widths. Combined with the height-adjustable anti-tilting component, the device can adapt to the processing needs of metal plates of various specifications, effectively expanding the application range of the device, while further enhancing the stability of the pushing process and improving the overall efficiency of metal rolling processing.

[0022] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in the illustrations in a simple schematic manner.

[0023] Please see Figure 1 The metal rolling and pushing device of this utility model includes a worktable 1. A PLC controller is installed on the worktable 1, which integrates stepper motor driver, servo motor driver and sensor signals to realize automated operation. Two fixed plates 4 are symmetrically arranged on the upper end of the worktable 1. A pushing component is installed on the worktable 1 between the fixed plates 4. The pushing component includes a push block 2, which is slidably installed on the worktable 1.

[0024] See Figure 1 , Figure 2 As shown, a lead screw 3 is rotatably mounted on the lower end of the worktable 1. The lead screw 3 is a C7 grade ball screw. The lead screw 3 is threadedly connected to the push block 2. A stepper motor is mounted on one end of the lead screw 3. The stepper motor is mounted on the worktable 1. The stepper motor is a 57 series two-phase stepper motor, equipped with a microstepping driver. Push plates 5 are provided on the side of the two fixed plates 4 that are close to each other. The push plates 5 are connected to the fixed plates 4 by an electric telescopic rod 17.

[0025] See Figure 1 , Figure 3 As shown, a diffuse reflection photoelectric sensor is installed on the inner side of each of the two push plates 5. If the sheet deviates from the push plate 5 during the pushing process, the system immediately stops the stepper motor to prevent the sheet from interfering with the rolling mill rolls. An anti-warping component is set between the two push plates 5. The anti-warping component includes two slide plates 6, which are installed on the corresponding push plates 5. A guide rod 16 is set above the anti-warping component. The two ends of the guide rod 16 are fixedly installed on the corresponding fixed plate 4 through the mounting plate 15.

[0026] See Figure 3 As shown, the guide rod 16 is slidably mounted on the slide plate 6. A lifting plate 7 is provided at the lower end of the side of the two slide plates 6 that are close to each other. A "height scale line" is provided between the lifting plate 7 and the slide plate 6. A universal wheel 8 is rotatably mounted on the lower end of the lifting plate 7. The universal wheel 8 is made of nylon. A guide rail 9 is mounted on the slide plate 6. The lifting plate 7 is slidably mounted on the guide rail 9. A lifting component is provided between the lifting plate 7 and the slide plate 6. The lifting component includes a screw 10. One end of the screw 10 is mounted on the lifting plate 7.

[0027] See Figure 3 , Figure 4 As shown, a vertical cylinder 14 is provided above the screw 10. The upper end of the vertical cylinder 14 is fixedly connected to the lifting plate 7. The lower end of the vertical cylinder 14 is sleeved on the screw 10, and the screw 10 and the vertical cylinder 14 are slidably arranged. A threaded cylinder 11 is rotatably installed on the slide plate 6. The threaded cylinder 11 is threadedly connected to the screw 10. A worm gear 12 is installed on the threaded cylinder 11, and a worm 13 is meshed on one side of the worm gear 12.

[0028] See Figure 2 , Figure 3 , Figure 4 As shown, the worm gear 13 is rotatably mounted on the lifting plate 7. The worm gears 13 on the same side are connected by a transmission rod. One end of the transmission rod is equipped with a drive source, which is mounted on the corresponding slide plate 6. The drive source is a small servo motor, which is connected to the transmission rod through a coupling. Multiple anti-tilting components are provided, and the multiple anti-tilting components are evenly distributed. There are at least two anti-tilting components.

[0029] The implementation principle is as follows: First, place the metal sheet to be rolled on the workbench 1 stably, start the electric telescopic rod 17, and adjust the distance between the two push plates 5 by the telescopic action of the electric telescopic rod 17. Continue to adjust until the two push plates 5 are respectively attached to the two sides of the metal sheet, so as to achieve lateral limiting of the sheet.

[0030] Next, the drive source is started. The drive source drives the worm gears 13 of all anti-tilting components on the same side to rotate synchronously through the transmission rod. The worm gears 13 and worm wheel 12 mesh. When the worm gears 13 rotate, they drive the worm wheel 12 and the threaded cylinder 11 to rotate synchronously. The threaded cylinder 11 is threadedly connected to the screw 10. The rotation of the threaded cylinder 11 will be converted into the up and down linear motion of the screw 10, which in turn drives the lifting plate 7 to slide along the guide rail 9. Continue to adjust until the universal wheel 8 at the lower end of the lifting plate 7 is completely in contact with the upper surface of the metal plate.

[0031] Then, the stepper motor is turned on, which drives the lead screw 3 at the lower end of the worktable 1 to rotate. The rotation of the lead screw 3 is converted into the linear sliding of the push block 2 along the worktable 1. The end of the push block 2 that is in contact with the metal sheet pushes the sheet smoothly and moves it along the worktable 1 toward the rolling mill rollers. During the pushing process, the precise control of the stepper motor ensures that the moving speed and displacement of the push block 2 are controllable, thereby ensuring the accuracy of the sheet pushing position. The universal wheel 8 that is in contact with the surface of the sheet rolls synchronously with the movement of the sheet. The universal wheel 8 holds the sheet in place to prevent it from warping upward or downward due to insufficient rigidity. It also uses the rolling characteristics to avoid generating additional resistance to the movement of the sheet, effectively preventing the sheet from interfering with the pushing device or the rolling equipment.

[0032] When the board moves the slide plate 6 in the pushing direction, the guide rod 16 provides stable guidance for the slide plate 6, preventing the anti-tilting component from deviating and further strengthening the multi-point stability limit of the board.

[0033] When pusher 2 pushes the metal sheet completely into the rolling mill rolls, the sheet pushing task is completed; turn off the stepper motor, the lead screw 3 stops rotating, and pusher 2 stops moving; if the next sheet needs to be processed, the stepper motor can be started in reverse to reset pusher 2 to the initial position along lead screw 3; at the same time, according to the specifications of the next sheet, repeat the steps of "adjusting the spacing of pusher 5 and adjusting the height of anti-warping component" to prepare for the next pushing operation.

[0034] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
