Description

Technical Field

[0001] This invention relates to the field of plate rolling machine technology, and in particular to a plate rolling machine and its usage method. Background Technology

[0002] A plate rolling machine is a device that uses work rollers to bend sheet metal into various shapes, such as cylindrical and conical parts. Currently, plate rolling machines are broadly classified into two-roll, three-roll, and four-roll types. A two-roll plate rolling machine has two rollers: an upper roller and a lower roller. A three-roll plate rolling machine has three rollers: an upper roller and two lower rollers. A four-roll plate rolling machine has four rollers: an upper roller, a lower roller, and two side rollers.

[0003] Four-roll plate bending machines typically achieve plate bending by adjusting the lower pressure roller and the side pressure rollers on both sides. However, traditional four-roll plate bending machines rely on manual adjustment. Manual adjustment suffers from insufficient precision in adjusting the height of the upper and lower pressure rollers and the spacing of the side pressure rollers. This can lead to excessive or uneven stress on the pressure rollers, causing plate deformation and jamming. Furthermore, the roller spacing affects the curvature of the rolled plate; manual adjustment also lacks precision, resulting in lower processing accuracy and impacting product quality. Summary of the Invention

[0004] To address the problems of the prior art, this invention provides a plate rolling machine and its usage method. The plate rolling machine includes a lifting device, a side roller device, upper and lower roller devices, and a roller drive device. The lifting device includes a base and a lifting drive assembly, a left lifting mechanism, and a right lifting mechanism mounted on the base. The left lifting mechanism is connected to the left end of the upper and lower roller devices and drives the lifting of the left end of the upper and lower roller devices. The right lifting mechanism is connected to the right end of the upper and lower roller devices and drives the lifting of the right end of the upper and lower roller devices. The lower end of the side roller devices is equipped with a front drive screw assembly and a rear drive screw assembly. This invention enables the plate rolling machine to automatically adjust the height of the upper and lower pressure rollers and the spacing of the side pressure rollers according to processing parameters such as the thickness of the plate material, the type of workpiece, and the curvature of the workpiece. This improves the adjustment efficiency, ensures the accuracy of the plate rolling machine's adjustment of the upper and lower pressure rollers and the front and rear pressure rollers, and improves the production quality of the product.

[0014] A method of using a plate rolling machine, employing the plate rolling machine described above, wherein the machine base is further provided with an operating table, includes the following steps:

[0015] 1. Initialize the settings through the control panel, including setting the thickness of the sheet metal to be processed, selecting the type of workpiece to be processed, and setting the curvature of the workpiece.

[0016] 2. Based on the thickness of the processing plate set in the initial configuration, the connecting rod motor drives the connecting rod to rotate, adjusting the distance between the upper and lower pressure rollers;

[0017] 3. The lifting height of the upper and lower roller devices can be adjusted according to the type of workpiece selected during initialization and the curvature of the workpiece. The left and right lifting mechanisms can be raised and lowered simultaneously or one side can be raised and lowered separately.

[0018] 4. Based on the type of workpiece selected during initialization and the curvature of the workpiece set, the lead screw motor controls the front drive plate and the rear drive plate to move in opposite directions or in opposite directions, and adjusts the distance between the front pressure roller and the rear pressure roller through the front drive plate and the rear drive plate;

[0019] 5. Reset the plate rolling machine after processing.

[0020] The beneficial effects of this invention are that the plate rolling machine includes a lifting device, a side roller device, an upper and lower roller device, and a roller drive device. The lifting device includes a base and a lifting drive assembly, a left lifting mechanism, and a right lifting mechanism mounted on the base. This enables the plate rolling machine to automatically adjust the height of the upper and lower pressure rollers and the spacing of the side pressure rollers according to processing parameters such as the thickness of the plate, the type of workpiece, and the curvature of the workpiece. This improves the adjustment efficiency, ensures the accuracy of the plate rolling machine's adjustment of the upper and lower pressure rollers and the front and rear pressure rollers, and improves the production quality of the product.

[0021] The left lifting mechanism is connected to the left end of the upper and lower roller assembly and drives the lifting of the left end of the upper and lower roller assembly. The right lifting mechanism is connected to the right end of the upper and lower roller assembly and drives the lifting of the right end of the upper and lower roller assembly. When it is necessary to control the curvature of the rolled plate and the left and right lifting mechanisms need to lift simultaneously, the clutch drum of the right lifting mechanism is in the working state. At this time, the lifting motor can control the lifting of the left and right lifting mechanisms simultaneously. When processing tapered parts, only the left lifting mechanism needs to lift. The clutch drum of the right lifting mechanism is in the clutch state, that is, the clutch lever is moved into the second clutch groove. At this time, the lifting motor controls the lifting of the left lifting mechanism alone.

[0022] When the rotating screw wheel or screw motor of the side roller device rotates, it can control the front drive plate and the rear drive plate to move in opposite directions or in opposite directions. By adjusting the distance between the front pressure roller and the rear pressure roller through the front drive plate and the rear drive plate, the curvature of the rolled plate can be controlled.

[0023] The connecting rod motor or connecting rod dial of the upper and lower roller device rotates, driving the connecting rod to rotate. The helical gears at both ends of the connecting rod drive the left slider screw and the right slider screw to rotate respectively. This, in turn, drives the left lower roller slider to move up and down along the left lower roller groove of the left roller seat, and drives the right lower roller slider to move up and down along the right lower roller groove of the right roller seat. This adjusts the distance between the upper and lower pressure rollers to adapt to the processing of plates of different thicknesses. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] like Figures 1-16As shown, the present invention provides a plate rolling machine, which includes a lifting device, a side roller device 6, an upper and lower roller device 7, and a roller drive device 8. The lifting device includes a base 1 and a lifting drive assembly 2, a left lifting mechanism 3, and a right lifting mechanism 4 mounted on the base 1. The lifting drive assembly 2 is connected to the left lifting mechanism 3 by chain drive, and the left lifting mechanism 3 is connected to the right lifting mechanism 4 by chain drive. A clutch lever 5 is installed on the right lifting mechanism 4. The left lifting mechanism 3 is connected to the left end of the upper and lower roller device 7 and drives the left end of the upper and lower roller device 7 to lift. The right lifting mechanism 4 is connected to the right end of the upper and lower roller device 7 and drives the right end of the upper and lower roller device 7 to lift. The roller drive device 8 is connected to the upper and lower roller device 7 by a universal joint 83.

[0044] The base 1 includes an upper fixed plate 11 and a lower fixed plate 12. The upper fixed plate 11 is used for mounting and fixing the side roller device 6, the upper and lower roller devices 7, and the roller drive device 8. The lower fixed plate 12 is used for mounting and fixing the left lifting mechanism 3 and the right lifting mechanism 4. The upper fixed plate 11 and the lower fixed plate 12 are fixedly connected by a connecting plate 13. The lower fixed plate 11 has two side panels 15, a left side panel 16, and a right side panel 17 on its lower perimeter. The lower fixed plate 12 has a partition 14 on its left side. The left side of the lower fixed plate 12 is fixedly connected to the partition 14, and the right side of the lower fixed plate 12 is fixedly connected to the right side panel 17. The lower fixed plate 12 is fixedly connected to the upper fixed plate 11 by the connecting plate 13, the partition 14, and the right side panel 17, which can increase the stability of the lower fixed plate 12 and provide stable support for the left lifting mechanism 3 and the right lifting mechanism 4 installed on the lower fixed plate 12.

[0045] A lifting drive assembly 2 is provided between the partition 14 and the left side plate 16. The lifting drive assembly 2 includes a lifting motor base 21 and a lifting motor 22. The lifting motor 22 is fixedly connected to the upper fixed plate 11 through the lifting motor base 21. The lifting drive assembly 2 is connected to the left lifting mechanism 3 through a chain to provide driving force to the left lifting mechanism 3.

[0046] The left lifting mechanism 3 includes an upper sleeve 31 and a lower sleeve 33. The upper sleeve 31 is fixedly connected to the upper fixed plate 11 via an upper sleeve seat 32, and the lower sleeve 33 is rotatably connected to the lower fixed plate 12 via a lower sleeve seat 34. A lifting screw 35 is provided inside both the upper and lower sleeves 31 and 33, respectively, and is rotatably connected to the upper and lower sleeves 31 and 33 via threads and balls. The lower sleeve 33 is located outside the upper fixed plate 11 and the lower fixed plate 12, and is equipped with an upper rotary drum wheel 36, a clutch drum wheel 37, and a lower rotary drum wheel 38 in sequence. The upper rotary drum wheel 36 and the clutch drum wheel 37 are rotatably connected to the upper sleeve 31 and the lower sleeve 33 of the lead screw, and the lower rotary drum wheel 38 is fixedly connected to the lower sleeve 33 of the lead screw. An upper rotary drum chain gear 3601 is provided on the outer side of the upper end of the upper rotary drum wheel 36. The upper rotary drum chain gear 3601 is connected to the lifting mechanism via a chain. The motor 22 is connected. The lower end of the upper rotating drum 36 is provided with an upper rotating drum engagement gear 3602. The upper end of the clutch drum 37 is provided with a clutch engagement gear 3701, and the lower end of the clutch drum 37 is provided with a clutch insertion gear 3702. A clutch ring groove 3703 is provided in the middle of the lower end of the clutch drum 37. The upper end of the lower rotating drum 38 is provided with a lower rotating drum insertion gear 3801, and a lower rotating drum chain gear 3802 is provided on the outer side of the lower end of the lower rotating drum 38. The clutch drum 3... The lower end of 7 is inserted and connected to the upper end of the lower rotating drum 38, and is engaged by the clutch insertion gear 3702 and the lower rotating drum insertion gear 3801. The lower end of the clutch drum 37 and inside the lower rotating drum 38 is provided with a compression spring 39. Under the elastic force of the compression spring 39, the clutch drum 37 slides upward inside the lower rotating drum 38 until the clutch engagement gear 3701 of the clutch drum 37 engages with the upper rotating drum engagement gear 3602 of the upper rotating drum 36.

[0047] In this embodiment, the lower sleeve 33 of the lead screw is limited between the upper rotating drum wheel 36 and the lower rotating drum wheel 38. The upper rotating drum wheel 36 has an upper rotating drum annular platform inside. The upper end of the upper rotating drum annular platform limits the lower end of the upper sleeve 31 of the lead screw. The upper end of the upper sleeve 31 of the lead screw is fixedly connected to the upper fixed plate 11 through the upper sleeve seat 32. The lower end of the upper rotating drum annular platform limits the upper end of the lower sleeve 33 of the lead screw. The lower end of the lower sleeve 33 of the lead screw is provided with a lower sleeve annular platform. The upper end face of the lower sleeve annular platform is used for the installation of the compression spring 39. The lower end face of the lower sleeve annular platform is limited and connected to the lower rotating drum wheel 38.

[0048] The working principle of the left lifting mechanism 3 is as follows: the lifting motor 22 drives the upper rotating drum wheel 36 to rotate through the chain. The upper rotating drum wheel 36 drives the clutch drum wheel 37 to rotate through the upper rotating drum engagement gear 3602. The clutch drum wheel 37 drives the lower rotating drum wheel 38 to rotate through the clutch insertion gear 3702. Because the lower rotating drum wheel 38 is fixedly connected to the lower sleeve of the lead screw 33, it drives the lower sleeve of the lead screw 33 to rotate. After being limited by the upper rotating drum wheel 36 and the lower rotating drum wheel 38, the lower sleeve of the lead screw 33 can only rotate. The lifting lead screw 35 inside the lower sleeve of the lead screw 33 then performs lifting and lowering movements.

[0049] To save on parts processing costs, the right lifting mechanism 4 has the same structure as the left lifting mechanism 3. The lower rotating drum 38 of the right lifting mechanism 4 and the left lifting mechanism 3 are connected by chain drive. A clutch lever 5 is installed on the clutch ring groove 3703 of the clutch drum 37 of the right lifting mechanism 4. The clutch lever 5 is installed and connected to the clutch ring groove 3703 through a lever fixing block 51. The lever fixing block 51 is installed inside the clutch ring groove 3703 and is fixedly connected to the clutch ring groove 3703. The lever fixing block 51 and the clutch lever 5 are rotatably connected through a rotating column. The right side plate 17 is provided with a first clutch groove 1701 and a second clutch groove 1702. A clutch pressure plate 18 is provided above the first clutch groove 1701 and the second clutch groove 1702. The clutch pressure plate 18 is fixedly connected to the right side plate 17. When the clutch drum 37 of the right lifting mechanism 4 is in the working state, the clutch lever 5 is located in the first clutch groove 1701. When the clutch drum 37 of the right lifting mechanism 4 is in the clutch state, the clutch lever 5 is located in the second clutch groove 1702.

[0050] The left lifting mechanism 3 is connected to the left end of the upper and lower roller assembly 7 and drives the left end of the upper and lower roller assembly 7 to rise and fall. The right lifting mechanism 4 is connected to the right end of the upper and lower roller assembly 7 and drives the right end of the upper and lower roller assembly 7 to rise and fall. When it is necessary to control the curvature of the rolled plate and the left lifting mechanism 3 and the right lifting mechanism 4 need to rise and fall simultaneously, the clutch drum 37 of the right lifting mechanism 4 is in the working state. At this time, the lifting motor 22 can control the left lifting mechanism 3 and the right lifting mechanism 4 to rise and fall simultaneously. When processing tapered parts, only the left lifting mechanism 3 needs to rise and fall. The clutch drum 37 of the right lifting mechanism 4 is in the clutch state, that is, the clutch lever 5 is moved into the second clutch groove 1702. At this time, the lifting motor 22 controls the rise and fall of the left lifting mechanism 3 alone.

[0051] In addition, when processing tapered parts, only when the right lifting mechanism 4 is raised or lowered, the clutch drum 37 of the right lifting mechanism 4 is in the clutch state, that is, the clutch lever 5 is moved into the second clutch groove 1702. At this time, the upper drum chain gear 3601 on the outer side of the upper end of the upper drum 36 is designed as the upper drum lever, so that the raising and lowering of the left and right lifting mechanisms 4 can be manually controlled separately by the upper drum lever.

[0052] The side roller device 6 is installed above the machine base 1. The side roller device 6 includes a left slide rail 61 and a right slide rail 62. The left slide rail 61 is provided with a left first slider 6101 and a left second slider 6102. The left first slider 6101 and the left second slider 6102 are respectively provided with a left front upright plate 63 and a left rear upright plate 64. The right slide rail 62 is provided with a right first slider 6201 and a right second slider 6202. The right first slider 6201 and the right second slider 6202 are respectively provided with a right front upright plate 65 and a right rear upright plate 66. The upper ends of the left front upright plate 63 and the right front upright plate 65 are provided with a front pressure roller 67. The front pressure roller 67 is connected to the left front upright plate 63 and the right front upright plate 65 through bearings. The upper ends of the rear upright plate 64 and the right rear upright plate 66 are provided with rear pressure rollers 68. The rear pressure rollers 68 are connected to the left rear upright plate 64 and the right rear upright plate 66 through bearings. The lower ends of the left front upright plate 63 and the right front upright plate 65 are provided with front drive plates 69. The lower ends of the left rear upright plate 64 and the right rear upright plate 66 are provided with rear drive plates 610. The lower part of the front drive plate 69 is provided with a front drive screw 611. The two ends of the front drive screw 611 are fixedly connected to the machine base 1 through the front screw seat 612. The front drive screw 611 is connected to the front drive plate 69 through the front screw nut 613. The outer side of the front drive screw 611 is provided with a screw wheel 614 and a front screw gear 615.

[0053] A rear drive screw 616 is provided below the rear drive plate 610. The two ends of the rear drive screw 616 are fixedly connected to the machine base 1 through the rear screw seat 617. The rear drive screw 616 is connected to the rear drive plate 610 through the rear screw nut 618. A screw motor 619 is provided on the outside of the rear drive screw 616. A rear screw gear 620 is provided on the outside of the rear drive screw 611. The rear screw gear 620 is meshed with the front screw gear 615.

[0054] The front drive screw assembly consists of a front drive plate 69, a front drive screw 611, a front screw seat 612, a front screw nut 613, a screw wheel 614, and a front screw gear 615. The rear drive screw assembly consists of a rear drive plate 610, a rear drive screw 616, a rear screw seat 617, a rear screw nut 618, a screw motor 618, and a rear screw gear 620.

[0055] The working principle of the side roller device 6 is as follows: rotating the lead screw wheel 614 drives the front drive lead screw 611 to rotate clockwise or counterclockwise. The front drive plate 69, driven by the front lead screw nut 613, then reciprocates along the front drive lead screw 611. Since the rear lead screw gear 620 meshes with the front lead screw gear 615, the rear drive lead screw 616 rotates in the opposite direction to the front drive lead screw 611. Consequently, the rear drive plate 610, driven by the rear lead screw nut 618, reciprocates along the rear drive lead screw 616. At this time, the front drive plate 69 and the rear drive plate 610 move towards each other or in opposite directions.
