Wire cutting machine

Abstract

The invention discloses a wire cutting machine. According to the wire cutting machine, the automatic counting function is achieved, the tightness degrees of wire feeding mechanisms can be adjusted, and cutting-off force is stable. The wire cutting machine comprises the wire feeding mechanisms, a straightening mechanism, a counting device, a cutting-off mechanism and a controller. Each wire feeding mechanism is formed in the mode that wire feeding shafts penetrate through an upper wire feeding wheel and a lower wire feeding wheel, a wire feeding belt wheel is connected to one end of each upper wire feeding wheel, and the wire feeding belt wheels are connected with a transmission wheel of a wire feeding motor through wire feeding belts to form a belt transmission structure. The counting device comprises a counting wheel, and a counter is installed at one end of the counting wheel, calculates the length of a steel wire by detecting the number of turns of rotation of the counting wheel and is connected to the controller through a line. Air pressure cutting is adopted for the cutting-off device, and the stable cutting-off force can be obtained through high-pressure air impacting. By means of the wire cutting machine, the pressing force of the wire feeding mechanisms can be adjusted at will, the counting function is achieved, and the cutting-off force is stable.

Description

technical field [0001] The invention relates to a wire cutter, in particular to a wire cutter which integrates the functions of steel wire straightening, counting and cutting. Background technique [0002] The most widely used in China at present is a wire cutter that uses a rotary straightener to straighten the steel wire and cuts the steel wire with a punching mechanism. This wire cutter is mainly composed of wire feeding, straightening, cutting, length fixing, wire doffing mechanism, body and transmission system, and has the following defects: [0003] 1. This kind of wire cutter does not have the function of automatic counting and limiting the cutting length, which leads to inaccurate straight length and large error; [0004] 2. The wire feeding mechanism is prone to loosening and the steel wire cannot be clamped tightly; [0005] 3. The cutting mechanism sometimes causes the steel wire to cut continuously due to insufficient cutting force. Contents of the invention ...
