Description

A high-speed automatic cutting machine

technical field

The utility model relates to the technical field of cutting machinery, in particular to a high-speed automatic cutting machine.

Background technique

Shoemaking and bagmaking are generally made by stitching pieces of different shapes. The pieces of different shapes are obtained by cutting fabrics on a cutting machine with a forming knife mold. The fabrics that can be cut can be leather, cloth, plastic and other materials. . The cutting machine is a common equipment used for fabric cutting and processing. When working, the movable die base installed on the cutting machine is driven by power to move on the guide rail. After moving to the set position, it is installed on the die base. The knife mold presses down to cut the fabric, and cuts out the pieces that are consistent with the shape of the knife mold from the fabric, thus completing the blanking work. The controller is generally used on the cutting machine to control the action of the cutting actuator, including controlling the lateral movement of the die base, vertical cutting action, rotating action of the die die, movement of the cutting table, etc. The controller can be a programmable PLD controller, or it can be It is a programmable computer, which is generally grasped and familiar to those skilled in the field of cutting machines, and belongs to the prior art, and the control of the specially designed cutting machine through the controller according to a specific control method does not belong to the prior art.

The hydraulic cutting machine is a relatively common cutting machine in modern times. Its characteristics are: when the punching head acts on the workpiece through the die, the pressure in the hydraulic cylinder does not reach the rated pressure, and the pressure will follow the contact (cut into the workpiece) ) time increases until the electromagnetic reversing valve receives a signal, the reversing valve changes direction, the punching head starts to reset, and the punching is completed.

In contrast, the cutting action of the mechanical transmission cutting machine is rigid, and its single cutting action time is much shorter than that of the hydraulic cutting machine, which means that the cutting frequency of the mechanical transmission cutting machine can be faster. At present, technicians in the field of cutting machines generally believe that although the cutting machine with mechanical transmission has faster speed, stable operation, and greater punching force, its biggest disadvantage is that it is noisy, so since the 1960s, it has gradually become a cutting machine with hydraulic transmission. machine instead.
