Description

Technical Field

[0001] This invention relates to the field of bending machine equipment, specifically a high-precision bending center based on numerical control intelligence. Background Technology

[0002] Bending machines are essential equipment in the sheet metal industry for bending and forming workpieces. Their function is to press steel plates into various shapes according to process requirements. Bending machines are divided into manual bending machines, hydraulic bending machines, and CNC bending machines. Manual bending machines are further divided into mechanical manual bending machines and electric manual bending machines. Bending is one of the most important steps in sheet metal manufacturing. The quality of bending directly affects the production of subsequent processes and the overall quality of the product. Currently, manual bending machines are gradually becoming unsuitable for production needs due to their low efficiency and low bending accuracy. Therefore, in order to improve the bending accuracy and work efficiency of sheet metal, an automatic CNC high-precision bending machine is needed to meet the above requirements. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] To meet the above requirements, this invention provides a high-precision bending center based on CNC intelligence. The steel plate to be bent is placed on an electric conveyor table at the front end. The electric conveyor table transports the steel plate to the groove of the bending mold on the bending table. Then, the operator controls the CNC machine via a control panel. The CNC machine issues commands to lower the hydraulic telescopic column, which bends the steel plate through the bending cutter head. After bending, the bending cutter head rises, and the steel plate is then conveyed out of the bending table via the conveyor table. The entire process is controlled by the CNC machine; the operator only needs to place the steel plate on the electric conveyor table and align it, thus achieving automated CNC operation and high-precision bending.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-precision bending center based on CNC intelligence, comprising a main housing, a worktable fixedly mounted on the top of the main housing, a bending table mounted on the top of the worktable, an electric conveyor mounted on the worktable, a bending cutter mounted on the worktable, support columns fixedly mounted at the four corners of the top of the worktable, a top plate fixedly mounted on the top of the four support columns, two hydraulic telescopic columns fixedly mounted at the bottom center of the top plate, and a fixed base at the bottom of the two hydraulic telescopic columns. A lifting plate is provided, which is slidably mounted on four support columns. A hydraulic power unit is fixedly mounted at the top center of the lifting plate, and a row of multiple cutter head mounting seats is fixedly mounted at the bottom center of the lifting plate. A bending cutter head is fixedly mounted inside the multiple cutter head mounting seats. The front end face and the top of the rear end face of the bending cutter head are both fixedly provided with mounting grooves. The bending cutter head is snapped into the inside of each cutter head mounting seat through the mounting grooves. Two fixing bolts are fixedly mounted on each cutter head mounting seat, and the bending cutter head is clamped tightly by each cutter head mounting seat through the fixing bolts.

[0007] Preferably, two partitions are fixedly installed in the middle of the main housing, three hydraulic lifting columns are fixedly installed in the two partitions, a bending table is fixedly installed on the top of the three hydraulic lifting columns, the bending table extends to the top of the workbench, and a placement groove is opened on the top of the bending table;

[0008] The above technical solution allows for the control of the bending table's height via a hydraulic lifting column, thus enabling better coordination with the electric conveyor table and adaptability to steel plates of various thicknesses.

[0009] Preferably, two rows of multiple buffer shock absorbers are fixedly arranged on both sides of the inner side of the placement groove, and a pad is fixedly arranged on the top of the multiple buffer shock absorbers in the same row.

[0010] Preferably, the inner side walls of the placement groove are fixedly provided with limiting grooves, and the outer sides of the two pads are fixedly provided with limiting sliders, and the limiting sliders of the two pads slide in the two limiting grooves respectively.

[0011] By using the above technical solution, a buffer damper is installed at the bottom of the bending die of the bending table. When bending steel plates and other sheet materials, the buffer damper can effectively reduce the rigid damage to the steel plate caused by the bending cutter head, and at the same time, it can also effectively protect the cutter head and the bending table.

[0012] Preferably, a box is fixedly installed at the front and rear ends of the bottom center of the workbench, a rotating motor is fixedly installed inside each of the two boxes, a rotating shaft is fixedly installed at the output end of each of the two rotating motors, a rotating table is fixedly installed on the top of each of the two rotating shafts, and an electric conveyor is fixedly installed on the top of each of the two rotating tables.

[0013] The above technical solution uses an electric conveyor to transport steel plates, thereby achieving the functions of automatic feeding and unloading.

[0014] Preferably, both ends of the bending cutter head are fixedly provided with fixing screw holes, and both ends of the bending cutter head are fixedly installed with fixing blocks through fixing screw holes;

[0015] The above technical solution uses a fixing block to limit the bending cutter head and prevent it from shifting.

[0016] Preferably, a CNC machine is fixedly installed on one side wall of the main housing, and a control panel is installed on the CNC machine via a moving rod;

[0018] Preferably, four bases are fixedly installed at the bottom of the main body, and a main body door is fixedly installed on the front end of the main body.

[0019] Working principle: This high-precision bending center based on CNC intelligence operates by first placing the steel plate to be bent on the electric conveyor table. After the steel plate is placed parallel to the bending table, the operator only needs to input instructions through the control panel to control the electric conveyor table to transport the steel plate to the bending die on the bending table. At this time, the CNC and control hydraulic telescopic column work to lower the bending cutter head to bend the steel plate. After bending is completed, the electric conveyor table transports the bent steel plate out. The whole process is fully automated, achieving the effect of intelligent CNC.

The snap-fit ​​installation method allows the bending head to be disassembled for easy replacement with different bending heads. Simultaneously, the bending die can also be disassembled for compatibility with different bending heads, making it flexible, convenient, and widely applicable. Attached Figure Description
