Technical Field

[0001] The present application relates to the technical field of plate rolling devices, and more specifically, to a steel plate rolling machine. Background Art

[0002] Plate rolling machine is a kind of equipment that uses working rollers to bend and shape sheet materials. According to the rotation and position changes of working rollers of different shapes, it can process parts of different shapes such as elliptical parts, arc parts, cylindrical parts, and conical parts. It is a very important processing equipment. The working principle of plate rolling machine is to use external forces such as hydraulic pressure and mechanical force to move the working rollers, so as to bend or roll the sheet materials.

[0003] In the Chinese invention patent application with the announcement number CN111744995A, an anti-rebound plate rolling machine is proposed, including a plate rolling machine body, the plate rolling machine body includes a fixed plate, a fixed roller, a mounting frame, and a movable rod. The fixed roller is rotatably connected to the fixed plate through a bearing. By setting a pressure roller device, and then controlling the movement of the servo motor and the electric telescopic rod through a programmable PLC controller with a set program, the pressure plate and the roller are controlled to always keep rolling and pressing down on the surface of one end of the plate after being rolled by the fixed roller and the movable roller, so as to prevent one end of the plate from rebounding after rolling.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the plate is easily tilted when entering the plate rolling machine, causing the plate to be rolled into an irregular shape, thus affecting the quality of the product. Summary of the invention

[0005] In order to solve the above problems, the present application provides a steel plate rolling machine.

[0006] The present application provides a steel plate rolling machine adopting the following technical solution:

[0007] A steel plate rolling machine comprises a base, two vertical plates fixed to the upper surface of the base and a plate rolling assembly arranged between the two vertical plates, a material guiding mechanism for preventing the steel to be rolled from tilting is arranged between the two vertical plates, the material guiding mechanism comprises a material guiding assembly and a driving assembly, the material guiding assemblies are provided with two groups and are symmetrically arranged, each group of the material guiding assemblies comprises a horizontal slider arranged on the base and a material guiding track arranged on the horizontal slider, and the driving assembly is used to drive the two horizontal sliders to move closer to or away from each other.

[0008] Through the above technical solution, when the steel to be rolled needs to be rolled, the staff must first use the driving assembly to drive the two horizontal sliders to move closer to or away from each other until the two guide rails cooperate and clamp the steel to be rolled. Then, the staff can use the rolling plate assembly to roll the steel. The guide rails on both sides cooperate with each other, which plays a good guiding role for the rolled steel, reduces the probability of the steel being skewed during the rolling process and affecting the rolling effect, and is beneficial to improving the quality of the rolled steel.

[0009] Furthermore, a horizontal slide groove is provided on the upper surface of the base for sliding connection of the horizontal slider, and the driving assembly includes a driving motor arranged on the base, a driving gear fixedly sleeved on the output shaft of the driving motor, and a bidirectional threaded rod rotatably installed on the inner wall of the horizontal slide groove, the bidirectional threaded rod is provided with two sections of threads with equal pitches and opposite rotation directions, the two horizontal sliders are respectively arranged on the two sections of threads of the bidirectional threaded rod and are threadedly connected to the bidirectional threaded rod, one end of the bidirectional threaded rod passes through the side wall of the horizontal slider close to the driving motor and is rotatably connected to the base, and the end of the bidirectional threaded rod is fixedly sleeved with a first driven gear meshing with the driving gear.

[0010] Through the above technical solution, when the driving assembly is needed to drive the two horizontal sliders to move closer to or away from each other, the staff needs to turn on the driving motor. After the driving motor works, it drives the driving gear to rotate, and the driving gear drives the first driven gear meshing with it and the bidirectional threaded rod fixed to the first driven gear to rotate. Since the bidirectional threaded rod is provided with two sections of threads with equal pitches and opposite rotation directions, the two horizontal sliders are respectively arranged on the two sections of the threads of the bidirectional threaded rod and are threadedly connected to the bidirectional threaded rod, so that the two horizontal sliders move closer to or away from each other until the distance between the two material guide tracks matches the steel to be rolled, and then the driving motor can be turned off, thereby facilitating the two material guide tracks to cooperate and guide the steel to be rolled.

[0011] Furthermore, a lifting cylinder is fixed on the upper surface of the horizontal sliding block, and the upper end of the piston rod of the lifting cylinder is fixedly connected to the bottom surface of the material guiding track.

[0012] Through the above technical solution, when the steel to be rolled needs to be rolled into different shapes, it is usually necessary to adjust the rolling assembly. In order to meet the rolling requirements, the feeding height of the steel also needs to be adjusted. At this time, the staff only needs to adjust the lifting cylinder to extend or shorten the piston rod of the lifting cylinder to adjust the height of the guide rail. When the height of the guide rail meets the steel rolling requirements, stop adjusting the lifting cylinder.

[0013] Furthermore, an upper slide groove is formed through each of the side walls of the vertical plate, a first slide groove is formed at a position of each of the side walls of the vertical plate close to the bottom wall of the upper slide groove, and two second slide grooves are formed on the side walls of the vertical plate on both sides of the first slide groove and are symmetrically arranged with respect to the first slide groove;

[0015] Furthermore, the lifting mechanism includes a transmission assembly and a lifting assembly, wherein the transmission assembly includes a lower rotating rod rotatably mounted on the side wall of the base, a driving wheel fixedly sleeved on the lower rotating rod, a second driven gear fixedly sleeved on the end of the lower rotating rod and meshing with the driving gear, an upper rotating rod rotatably mounted on the side wall of the vertical plate close to the driving motor, a driven wheel fixedly sleeved on the upper rotating rod, a lower transmission belt for connecting the driven wheel and the driving wheel, and a driving bevel gear fixedly sleeved on the upper rotating rod;

[0016] The lifting assembly includes a gantry fixed to the upper surface of the vertical plate, a transmission shaft rotatably mounted at the bottom of the gantry, a driven bevel gear fixedly sleeved on the transmission shaft and meshing with the driving bevel gear, an upper slider sleeved on the transmission shaft and threadedly connected to the transmission shaft, and the upper slider is arranged in an upper slide groove and slidably connected to the upper slide groove;

[0017] A T-shaped slot is provided on the side wall of the upper surface of the base near the edge of the base, a T-shaped slider is installed in the T-shaped slot and is slidably connected to the T-shaped slot, the top of the T-shaped slider is fixed to the bottom of the driving motor, and two positioning holes are provided on the bottom wall of the T-shaped slot, the two positioning holes are respectively located near the position of the bidirectional threaded rod and the position near the lower rotating rod, and a positioning component for positioning the T-shaped slider is provided on the T-shaped slider.

[0018] Through the above technical scheme, when the staff places the steel to be rolled between the upper pressure roller, the first lower pressure roller and the second lower pressure roller, the staff needs to position the assembly so that the positioning effect of the positioning assembly on the T-shaped slider disappears, and then the staff needs to move the T-shaped slider to the side close to the lower rotating rod so that the active gear is meshed with the second driven gear, and use the positioning assembly to fix the T-shaped slider at the positioning hole close to the side of the lower rotating rod so that the position of the driving motor can be fixed. After the staff turns on the driving motor, the driving motor drives the active gear to rotate, and the active gear drives the second driven gear meshed with the active gear, and the lower driven gear fixed with the second driven gear. The rotating rod and the driving wheel fixed to the lower rotating rod rotate, and the driven wheel rotates under the action of the lower transmission belt, so that the upper rotating rod fixed to the driven wheel, the driving bevel gear fixed to the upper rotating rod, the driven bevel gear meshed with the driving bevel gear, and the transmission shaft fixed to the driven bevel gear all rotate. Since the upper slider is threadedly connected to the transmission shaft, the upper slider moves downward along the upper slide until the upper pressure roller cooperates with the first lower pressure roller and the second lower pressure roller and presses against the steel to be rolled. The staff needs to turn off the drive motor, and then the staff needs to turn on the rotating motor. After the rotating motor works, it drives the first lower pressure roller to rotate so that the rolled steel moves forward. When the rolled steel needs to be unloaded, the staff needs to turn on the drive motor and rotate it in the opposite direction, so that the upper pressure roller moves upward in the vertical direction until the upper pressure roller is separated from the first lower pressure roller and the second lower pressure roller, so that the staff can unload the rolled steel conveniently.

[0019] Furthermore, the positioning assembly includes a positioning rod that is penetrated through the horizontal portion of the T-shaped slider and is gap-matched with the T-shaped slider, and a baffle fixed to the upper end of the positioning rod, and the lower end of the positioning rod is plug-fitted with the positioning hole.

[0020] Through the above technical solution, when the positioning assembly is needed to position the T-shaped slider, the staff only needs to align the lower end of the positioning rod with the positioning hole to fix the T-shaped slider in the T-shaped slide groove.

[0021] Furthermore, a spring is sleeved on the positioning rod, the upper end of the spring is fixed to the bottom surface of the baffle, and the lower end of the spring is fixed to the upper surface of the horizontal portion of the T-shaped sliding block.

[0022] Through the above technical solution, under the elastic force of the spring, the lower end of the positioning rod is always plugged into the positioning hole, thereby enhancing the stability of the T-shaped slider and the drive motor during use.

[0023] Furthermore, the two gantries are provided and are symmetrically arranged about the upper pressure roller, the two transmission shafts are provided and are respectively installed on the two gantries, the two upper sliders are provided and are respectively arranged in the two upper slide grooves, the two ends of the upper pressure roller are respectively rotatably connected to the two upper sliders, the two transmission shafts are linked by a linkage assembly, the linkage assembly includes a transmission wheel fixedly mounted on the transmission shaft, the two transmission wheels are provided and are respectively located on the two transmission shafts, and the linkage assembly also includes an upper transmission belt for connecting the two transmission wheels.

[0024] Through the above technical solution, two upper sliders are provided and respectively arranged in two upper slide grooves, and the two ends of the upper pressure roller are respectively connected to the two upper sliders for rotation, thereby enhancing the stability of the upper pressure roller during use. In order to make the upper sliders on both sides move synchronously, after turning on the drive motor, the staff rotates the transmission shaft on the side close to the drive motor, and under the action of the upper transmission belt, the transmission shaft on the side away from the drive motor also rotates, so that the transmission shafts on both sides rotate synchronously, thereby making the upper sliders on both sides and the upper pressure roller move synchronously, which is conducive to enhancing the stability of the upper pressure roller during the up and down movement.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] (1) In the present application, when the steel to be rolled needs to be rolled, the staff first needs to use the driving assembly to drive the two horizontal sliders to move closer to or farther from each other until the two guide rails cooperate and clamp the steel to be rolled. Then, the staff can use the rolling plate assembly to roll the steel. The guide rails on both sides cooperate with each other, thereby playing a good guiding role for the steel to be rolled, reducing the probability of the steel being skewed during the rolling process and affecting the rolling effect, which is conducive to improving the quality of the rolled steel;

[0027] (2) In the present application, when the steel to be rolled needs to be rolled into different shapes, the rolling assembly usually needs to be adjusted. In order to meet the rolling requirements, the feeding height of the steel also needs to be adjusted. At this time, the staff only needs to adjust the lifting cylinder to extend or shorten the piston rod of the lifting cylinder to adjust the height of the guide rail until the height of the guide rail meets the steel rolling requirements, and then stop adjusting the lifting cylinder;

[0028] (3) In the present application, two upper sliders are provided and are respectively arranged in two upper slide grooves, and the two ends of the upper pressure roller are respectively connected to the two upper sliders for rotation, thereby enhancing the stability of the upper pressure roller during use.

[0044] The implementation principle of a steel plate rolling machine in the embodiment of the present application is as follows: when it is necessary to roll the steel to be rolled, the staff first turns on the driving motor 421. After the driving motor 421 works, it drives the driving gear 422 to rotate, and the driving gear 422 drives the first driven gear 424 meshing therewith and the bidirectional threaded rod 423 fixed to the first driven gear 424 to rotate.

When the steel to be rolled needs to be rolled into different shapes, the rolling assembly usually needs to be adjusted. In order to meet the rolling requirements, the feeding height of the steel also needs to be adjusted. At this time, the staff only needs to adjust the lifting cylinder 4111 to extend or shorten the piston rod of the lifting cylinder 4111 to adjust the height of the guide rail 412. When the height of the guide rail 412 meets the steel rolling requirements, stop adjusting the lifting cylinder 4111.

[0045] After the staff places the steel to be rolled between the upper pressure roller 31, the first lower pressure roller 34 and the second lower pressure roller 37, the staff needs to position the assembly 6 so that the positioning effect of the positioning assembly 6 on the T-shaped slider 121 disappears, and then the staff needs to move the T-shaped slider 121 to the side close to the lower rotating rod 511, so that the active gear 422 is meshed with the second driven gear 513, and use the positioning assembly 6 to fix the T-shaped slider 121 at the positioning hole 13 close to the side of the lower rotating rod 511, so that the position of the drive motor 421 can be fixed. After the staff turns on the drive motor 421, the drive motor 421 drives the active gear 422 to rotate, and the active gear 422 drives the second driven gear 513 meshed with the active gear 422, the lower rotating rod 511 fixed with the second driven gear 513, and the lower rotating rod 511 fixed with the lower driven gear 513. The driving wheel 512 fixed by the rotating rod 511 rotates, and the driven wheel 515 rotates under the action of the lower transmission belt 516, so that the upper rotating rod 514 fixed to the driven wheel 515, the driving bevel gear 517 fixed to the upper rotating rod 514, the driven bevel gear 523 meshing with the driving bevel gear 517, and the transmission shaft 522 fixed to the driven bevel gear 523 all rotate. Since the upper slider 524 is threadedly connected to the transmission shaft 522, the upper slider 524 moves downward along the upper slide groove 21 until the upper pressure roller 31 cooperates with the first lower pressure roller 34 and the second lower pressure roller 37 and presses against the steel to be rolled. Then, the staff needs to turn off the driving motor 421, and then the staff needs to turn on the rotating motor 331. After the rotating motor 331 works, it drives the first lower pressure roller 34 to rotate so that the rolled steel moves forward. When the rolled steel needs to be unloaded, the staff needs to start the drive motor 421 and rotate it in the reverse direction, so that the upper pressure roller 31 moves upward in the vertical direction until the upper pressure roller 31 is separated from the first lower pressure roller 34 and the second lower pressure roller 37, thereby facilitating the staff to unload the rolled steel.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
