Novel wire cutting machine

Abstract

The invention provides a novel wire cutting machine which comprises a wire feeding mechanism, a straightening mechanism, a wire cutting mechanism and a control system. The wire feeding mechanism, the straightening mechanism and the wire cutting mechanism are arranged in sequence. The control system controls the wire feeding mechanism and the wire cutting mechanism. The wire cutting mechanism comprises a pneumatic control device, an impact hammer, a spring, an air cylinder, a collision block, a fixed cutter, a moving cutter, a guide rod and a plate support. The impact hammer, the spring and the collision block are sequentially connected and are arranged in the air cylinder. The pneumatic control device is connected with the air cylinder. The moving cutter is arranged under the collision block. The fixed cutter is provided with a wire passing hole. The moving cutter is provided with a cutter hole. When the pneumatic control device is switched off, the wire passing hole and the cutter hole are coaxial. According to the novel wire cutting machine, the impact hammer in the wire cutting mechanism drives the cutter to move at a high speed under the action of air pressure, cut-off motion can be instantly completed, and the quality of cross sections is guaranteed. Meanwhile, wire feeding wheels in the wire feeding mechanism press metal wires tightly through the air cylinder and are driven by a servo motor to feed the metal wires. The control system is used for automatically and accurately controlling the feeding length of the wires.

Description

technical field [0001] The invention relates to a cutting device, in particular to a new wire cutter for cutting metal wires. Background technique [0002] At present, most wire cutting machines are mainly composed of wire feeding, straightening, cutting, length fixing, fuselage and transmission mechanism. The traditional wire cutting machine uses a mechanically controlled cutter device for cutting, and a length control mechanism for wire length control, but in actual production, due to the low cutting speed of the mechanically controlled cutter device, the quality of the cut surface is poor. The metal wire produced by this traditional wire cutting machine cannot meet special usage requirements, such as the production of wire frames. Contents of the invention [0003] The problem to be solved by the present invention is to provide a new type of shredding machine, which can move quickly in the cylinder with the help of the impact hammer in the shredding mechanism, and the ...
