Description

Technical Field

[0001] This invention belongs to the technical field of metal profile forming and processing equipment, and specifically relates to a sheet metal through-type pressing device. Background Technology

[0002] A milling machine is a welding auxiliary device that uses a high-speed milling cutter head to cut weld bevels on steel plates before welding. It is widely used in boiler, pressure vessel, shipbuilding, power, petroleum, chemical machinery, and engineering machinery manufacturing. It can process straight edges, upper and lower bevels, U-shaped bevels, etc. of various medium and low carbon steel plates, stainless steel plates, and aluminum plates before welding.

[0003] When milling sheet metal, it is necessary to clamp the sheet metal to prevent it from shifting and to ensure the accuracy of the processing. Traditional milling machines require the sheet metal to be fixed on the worktable, which is a cumbersome process with low clamping efficiency. When the milling unit moves to mill the sheet metal, the milling cutter head is exposed, which easily generates metal chips during processing, causing not only environmental pollution but also posing a serious threat to the personal safety of the operators. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a plate-through pressing device.

[0005] This invention is achieved through the following technical solution: A through-type pressing device for sheet metal includes a frame, characterized in that: a pressing roller device and a support roller device are installed on the frame for pressing sheet metal; the pressing roller device consists of several pressing roller groups, and large pressing rollers or small pressing rollers are installed on the pressing roller groups, with the large pressing rollers and small pressing rollers arranged alternately; the support roller device consists of large support rollers and small support rollers arranged alternately, with the large support rollers corresponding to the large pressing rollers and the small support rollers corresponding to the small pressing rollers.

[0006] The large or small pressure roller is mounted on the pressure roller seat, which is connected to the cylinder via a connecting flange. The cylinder is mounted on the horizontal plate, which is fixed to the frame.

[0007] The top of the pressure roller seat is connected to a linear shaft, which is mounted on a linear bearing, and the linear bearing is fixed to the horizontal plate.

[0008] The large and small rollers are mounted on the roller base.

[0009] The large pressure roller, small pressure roller, large support roller, and small support roller are respectively mounted on the axle via bearings.

[0010] The large pressure roller, small pressure roller, large support roller, and small support roller are respectively equipped with inner and outer covers on their inner and outer sides.

[0011] The beneficial effects of this invention are: the pressure roller and the support roller clamping device work together to ensure smooth feed when milling the bevel of the plate; the pressure roller and the support roller form a stepped layout, which reduces the distance of the plate protruding from the roller, effectively suppresses the vibration generated when milling the plate, and improves the processing accuracy.

[0012] The multi-unit combined structure balances rigidity and space utilization. It is composed of milling units and pressure roller housing, which can be flexibly separated and closed, balancing working stability and maintenance convenience. Attached Figure Description

Detailed Implementation

[0015] The attached figure illustrates a specific embodiment of the present invention. This embodiment includes a frame 1, on which a pressure roller device 2 for pressing the plate and a support roller device 3 are mounted. The pressure roller device 2 consists of several pressure roller groups 4, each with a large pressure roller 5 or a small pressure roller 6, arranged alternately. The support roller device 3 consists of large support rollers 7 and small support rollers 8 arranged alternately, with the large support rollers 7 corresponding to the large pressure rollers 5 and the small support rollers 8 corresponding to the small pressure rollers 6.

[0016] A large pressure roller 5 or a small pressure roller 6 is mounted on a pressure roller seat 9. The pressure roller seat 9 is connected to a cylinder 11 via a connecting flange 10. The cylinder 11 is mounted on a horizontal plate 12, which is fixed to the frame 1. A linear shaft 13 is connected to the top of the pressure roller seat 9. The linear shaft 13 is mounted on a linear bearing 14, which is fixed to the horizontal plate 12. A large support roller 7 and a small support roller 8 are mounted on a support roller seat 15.

[0017] The large pressure roller 5, the small pressure roller 6, the large support roller 7, and the small support roller 8 are respectively mounted on the axle 17 via bearings 16. Inner cover 18 and outer cover 19 are respectively installed on the inner and outer sides of the large pressure roller 5, the small pressure roller 6, the large support roller 7, and the small support roller 8.

[0018] The plate-passing clamping device of the present invention consists of a frame 1, a pressure roller device 2, and a support roller device 3. The frame 1 is welded from steel plates, with a reasonable and compact structure and good rigidity. After the frame 1 is combined with the milling unit box, it forms a closed cavity structure. This structure can realize the closed linkage of the box in the working state, completely eliminating the risk of iron filings flying, and automatically separating during maintenance. It not only ensures the stability of processing, but also provides sufficient operating space for tool replacement and equipment maintenance, and improves operational safety.

[0019] The pressure roller device 2 consists of a horizontal plate 12, a cylinder 11, a connecting flange 10, a linear shaft 13, a linear bearing 14, a roller assembly, and a pressure roller seat 9. The pressure roller device 2 has a stepped structure, where the roller assembly is assembled from rollers, bearings 16, axles 17, and inner and outer covers. The pressure roller seat 9 has two sets of pressure rollers on both sides, arranged in a stepped layout, with an additional enclosed structure on the outer side to prevent milling chips from entering the device.

[0020] The horizontal plate 12 is fixed to the frame 1 with screws. The cylinder 11 and the linear bearing 14 are installed on the horizontal plate 12. The pressure roller seat 9 is connected to the output end of the cylinder 11 via the connecting flange 10. The linear shaft 13 and the linear bearing 14 are precisely matched to achieve the guiding function. Driven by the cylinder 11, the roller group can be driven to complete the automatic pressing action on the plate.

[0021] The roller support device 3 consists of a roller support assembly and a roller support seat 15. The roller support assembly is arranged in a stepped manner on the roller support seat 15. The entire device is installed on the frame beam. The stepped design of the frame 1 and the pressure rollers form a matching structure, which can be adapted to the milling requirements of the upper and lower bevels of the plate.

[0022] This device, together with the milling unit, forms a fully enclosed machining space, fundamentally avoiding the problem of metal shavings flying due to exposed milling cutters and ensuring the personal safety of operators. Simultaneously, the coordinated clamping of the upper and lower stepped roller groups achieves zero movement during sheet metal milling, significantly improving machining accuracy. The device's split-type linkage structure allows for both stable operation in working mode and convenient operation in maintenance mode, greatly enhancing the overall performance of the equipment.
