Description

Technical Field

[0001] This utility model relates to the field of metal sheet cutting machine technology, and in particular to a metal sheet cutting machine that facilitates workpiece orientation adjustment. Background Technology

[0002] Metal sheet cutting machines are a type of equipment used for separating various metal sheets such as steel, aluminum, and copper plates into fixed lengths, fixed widths, or irregular shapes. For example, a metal sheet cutting machine that facilitates workpiece orientation adjustment (publication number: CN109396521B) places the metal sheet on the cutting table, aligning the area to be cut with the cutting blade. The metal sheet is manually pressed down, which in turn pushes the lifting mechanism's push rod downwards. The drive motor is then activated, causing the cutting blade to move and cut the metal sheet. After one cut, the worker removes the pressure on the metal sheet. In its natural state, the push rod is lifted upwards by the buoyancy of the airbag and the restoring force of the tension spring, providing a fulcrum. The worker can then easily rotate the metal sheet and adjust its orientation towards the cutting blade for cutting different areas.

[0003] Although the orientation of the board material was adjusted by using a lifting mechanism and manual rotation, relying entirely on manual intervention has the following obvious drawbacks: manual rotation based on experience, the lack of angle rulers or limit devices, the inability to guarantee repeatability, and the large cumulative error during multiple cuts, resulting in subsequent dimensional deviations or uneven splicing gaps.

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] like Figures 1-6 As shown, a metal sheet cutting machine that facilitates workpiece orientation adjustment includes a cutting table 1. Two parallel mounting frames 3 are fixedly installed on the table surface of the cutting table 1, and one of the mounting frames 3 is equipped with a;

[0029] The displacement mechanism includes a first slider 2 inserted into one of the mounting brackets 3 and sliding horizontally. An electric push rod 8, which extends and retracts towards the cutting table 1, is fixedly mounted on the side of the first slider 2. A coaxially distributed connecting shell 9 is fixedly mounted on the telescopic end of the electric push rod 8. In actual use, the position of the first slider 2 on the mounting bracket 3 is adjusted according to the position of the workpiece on the cutting table 1. Then, the electric push rod 8 extends to push the connecting shell 9 downwards. Several hydraulic rods 16, arranged in a circular array around the electric push rod 8, are fixedly mounted through the bottom edge of the connecting shell 9. The telescopic ends of the hydraulic rods 16 penetrate the bottom of the connecting shell 9. Below the connecting shell 9 are longitudinal rollers 19, transverse rollers 18, and two rotating rollers 17. The hubs of the longitudinal rollers 19, transverse rollers 18, and two rotating rollers 17 are arranged in a circular array around the electric push rod 8 and are fixedly connected to the telescopic ends of the hydraulic rods 16. The tire center axes of the longitudinal rollers 19 and transverse rollers 18 are perpendicularly distributed. The tires of the rotating rollers 17 are arranged in a circular array around the electric push rod 8. In actual use, the extension of the hydraulic rods 16 at different positions can push the corresponding longitudinal rollers 19, transverse rollers 18, or rotating rollers 17 to descend and use the tires to press against the workpiece surface. Different tires produce different effects when pressing against the workpiece surface. Specifically, the longitudinal rollers 19, transverse rollers 18, and rotating rollers 17 used in this solution are all commercially available electric wheels. When the longitudinal roller 19 descends to press against the workpiece surface, its tires rotate and, under the action of friction, can drive the workpiece to move along the length direction of the cutting table 1. When the transverse roller 18 descends to press against the workpiece surface, its tires rotate and, under the action of friction, enables the workpiece to slide along the width direction of the cutting table 1. When the two rotating rollers 17 descend to press against the workpiece surface, the friction between their tires and the workpiece enables the workpiece to rotate around the center of the connecting shell 9 on the cutting table 1. Therefore, the displacement mechanism is used for workpiece position adjustment.

[0030] In addition, when the longitudinal roller 19, the transverse roller 18 and the rotating roller 17 simultaneously press against the surface of the workpiece, the position of the workpiece can be fixed.

[0031] Another mounting bracket 3 is equipped with a cutting assembly;

[0032] The cutting assembly includes a second slider 11 slidably connected to another mounting bracket 3. A longitudinally lifting rail 14 is inserted into one side of the second slider 11. A cutting machine 10 is fixedly installed at the bottom end of the rail 14. A pneumatic telescopic rod 15 is provided between the top end of the rail 14 and the top edge of the second slider 11. The cutting assembly is used for workpiece cutting. The table surface of the cutting table 1 is through the cutting machine 10 in the sliding direction. In actual use, the extension of the pneumatic telescopic rod 15 causes the rail 14 to drive the cutting machine 10 to rise, creating a distance between the cutting machine 10 and the table surface of the cutting table 1, which facilitates the passage of the workpiece and makes it easy to adjust the width of the workpiece to be cut. In actual cutting, the retraction of the pneumatic telescopic rod 15 causes the rail 14 to drive the cutting machine 10 to fall and cut the workpiece. The second slider 11 slides along the surface of the mounting bracket 3, allowing the cutting machine 10 to slide along the through-hole of the table surface of the cutting table 1, thus achieving the cutting of the workpiece.

[0033] The mounting bracket 3 is rotatably connected to an electric lead screw 20 relative to the inner wall. The two electric lead screws 20 are respectively threaded to the side of the first slider 2 and the second slider 11. By driving the electric lead screw 20 to rotate by installing a motor on the outside of the mounting bracket 3, the first slider 2 or the second slider 11 with the corresponding threaded connection can slide along the surface of the mounting bracket 3.

[0034] The cutting table 1 is equipped with;

[0035] The auxiliary mechanism includes several rollers 4 embedded and rotatably mounted on the surface of the cutting table 1. The central axis of the rollers 4 is set parallel to the sliding direction of the first slider 2. The rollers 4 facilitate the movement of the workpiece along the width direction of the cutting table 1 by rolling to reduce the friction between the workpiece and the bottom of the workpiece. The auxiliary mechanism is used to assist in the adjustment of the workpiece direction. The auxiliary mechanism also includes several frame plates 5 embedded in the surface of the cutting table 1. The outer side of the frame plate 5 is rotatably connected to the end face of the adjacent roller 4. A connecting plate 6 is set inside the frame plate 5. Several balls 7 are embedded and rotatably mounted on the upper surface of the connecting plate 6. A lifting frame 12 that penetrates the bottom surface of the cutting table 1 is fixedly installed on the lower surface of the connecting plate 6. An electric telescopic rod 13 is set between the lifting frame 12 and the bottom of the cutting table 1. Specifically, the electric telescopic rod 13 is retracted to make the lifting frame 12 drive the connecting plate 6 to rise to a height higher than the rollers 4. The balls 7 on the upper surface of the connecting plate 6 can be used to support the bottom of the workpiece. The rolling of the balls 7 facilitates the sliding of the workpiece along the length direction of the cutting table 1 and the rotation of the workpiece on the cutting table 1.

[0036] Working principle: During the workpiece cutting process, the electric push rod 8 extends to push the connecting shell 9 down until the longitudinal roller 19, transverse roller 18 and rotating roller 17 simultaneously press against the workpiece surface to fix the workpiece position. When it is necessary to adjust the direction and position of the workpiece, the cutting machine 10 first rises a certain height, and the connecting shell 9 rises a certain distance. According to the direction of adjustment, the hydraulic rods 16 at different positions in the connecting shell 9 extend to make the longitudinal roller 19, transverse roller 18 or rotating roller 17 descend and press against the workpiece surface with tires. When the transverse roller 18 or rotating roller 17 presses against the workpiece surface, the bottom surface of the workpiece is supported and lifted by the ball bearings 7 on the surface of several rising connecting discs 6, so that the workpiece can move along the length direction, width direction or rotate along the cutting table 1.

[0037] The wiring diagrams for the electric push rod 8, cutting machine 10, electric telescopic rod 13, pneumatic telescopic rod 15, hydraulic rod 16, and motor in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the electric push rod 8, cutting machine 10, electric telescopic rod 13, pneumatic telescopic rod 15, hydraulic rod 16, and motor will not be explained in detail.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
