The cold drawing machine can be roughly divided into three separated machines and a frame machine according to the structure mode of the machine body. According to the transmission mode, the machine can be divided into various types such as chain type, hydraulic transmission type, rack type, screw rod type and the like. The drawing trolley is supported by two I-shaped guide rails and driven by a main oil cylinder, so that the trolley runs along the I-shaped guide rails. The main oil cylinder and the drawing trolley can be axially fixed with the trolley body through an adjustable split piston. When drawing the steel tube, firstly, the core rod is inserted into the inner hole of the tube, then the core head is installed, and then the front end of the steel tube which is inserted with the core head is pushed out of the die drawing seat. And starting the pre-tightening cylinder to enable the threading die to clamp the steel pipe, enabling the drawing trolley to be at the initial position, and starting the main oil cylinder to start drawing. When drawing is finished, the pre-tightening cylinder acts, the screw die loosens the steel pipe fork head to push the drawn finished product pipe to be separated from the vehicle body, and meanwhile the sliding block moves in the opposite direction, so that the plug head rapidly exits from the pipe, so that smooth discharging is realized. And because the volume of the vice is larger in the cold-drawing trolley, the area of the cold-drawing trolley is greatly increased after three vices are arranged, so that the whole volume of the equipment must be greatly enlarged after the positions of the grinding tool and the vices in the die-drawing seat correspond to each other, and meanwhile, the connecting structure of the cold-drawing trolley and the power chain is not reasonable enough, an additional power device is required to drive the tiger hook to be connected with the power chain, and the mechanical control cannot be carried out.
The patent CN207592448U discloses a full-automatic three-wire cold drawing machine, which comprises a main support and a drawing machine, wherein a holding plate is arranged on a frame body in the middle of the main support, the holding plate is welded and fixed with the frame body of the main support, sliding top plates are arranged on two sides of the top end of the main support, a scale is arranged on the sliding top plate on one side, a sliding rail is arranged on one side wall corresponding to the two sliding top plates, the sliding rail is in embedded sliding connection with pulleys on two side ends of the drawing machine, a drawing hole is arranged outside the drawing machine, linking frames are arranged at two side ends adjacent to the drawing hole, one end of each linking frame is welded and fixed with the side end of the drawing machine, and the two ends are embedded in sliding structures, so that the drawn steel pipes are effectively collected and processed in a unified manner, thereby saving a large amount of time for sorting and planning, and the motors are respectively and drawn steel pipes by a main control chip, Information analysis and execution of the drawing equipment and the information receiver realize automation of machine drawing, and therefore fatigue caused by manual supervision is avoided.
The full-automatic three-wire cold drawing machine has the following defects: 1. when the full-automatic three-wire cold drawing machine is used, a large amount of manpower is consumed in production to carry out cold drawing, so that the overall production cost is greatly increased; 2. when the full-automatic three-wire cold drawing machine is used, the products cannot be discharged automatically well, and the automation degree of the whole machine is greatly reduced.
