Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a multi-functional bending machine for machining. Background Technology

[0002] A bending machine is a machine that can bend sheet metal. 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. Hydraulic bending machines can be classified according to their synchronization method into torsion shaft synchronization, mechanical-hydraulic synchronization, and electro-hydraulic synchronization. Hydraulic bending machines can also be classified according to their motion method into top-moving type and bottom-moving type.

[0003] In related technologies, traditional bending machines can only bend once, and can only process the required bending once. Their functions are relatively simple. When it is necessary to cut the bent steel, a cutting machine is required. This requires placing the bent steel on the cutting machine, which is too troublesome and reduces work efficiency. Cutting cannot be performed on the bending machine. Therefore, we propose a multi-functional bending machine for machining.

First, the metal sheet to be processed is placed in the placement groove 21 on the placement plate 19. The placement plate 19 is movably mounted on the guide rail 3 by the clamping plate 20 fixed at its lower end to ensure the stability of the sheet. The servo motor 14 on the left mounting bracket 5 drives the positioning baffle to descend to the appropriate position and uses the positioning groove on the guide rail 3 to accurately position the metal sheet. If cutting is required first, the second screw 10 in the plate 9 is adjusted to rotate, driving the mounting block 11 and the cutter 13 below it to move back and forth along the guide rail 3 to the designated position. Then, the telescopic hydraulic cylinder 6 controls the cutter 13 to descend, and the cutting work of the metal sheet is completed through the cutting groove 24 on the placement plate 19. In this step, the position of the cutter 13 is adjustable to avoid interference with the bending head 15. The motion interference; once the sheet metal is ready, the servo motor 14 on the right mounting bracket 5 drives the bending head 15 to descend to a suitable height, and then performs the bending action according to the preset angle. The bending head 15 is replaceable, which means that different shapes or sizes of bending heads 15 can be replaced according to different bending requirements; the bottom of the support plate 1 is equipped with a conveyor belt system, which is driven by the transmission motor 22 to rotate the active roller, thereby driving the entire conveyor belt 17 and the transmission columns located on it to move. These transmission columns will push the transmission baffle under the placement plate 19, so that the placement plate 19 and the metal sheet on it move forward together to achieve automated conveying; as the conveyor belt 17 moves forward, the metal sheet is sent into the processing area and repeats the above-mentioned positioning, cutting (if necessary), bending and other processes, so as to achieve a continuous production process; once the processing is completed, the equipment can be stopped manually or through the control system, the finished product can be taken out and the site can be cleaned up to prepare for the next processing.
