Die box tuning roll device on straight wire drawing machine

Abstract

The invention relates to a mold box tuning roller device on a straight wire drawing machine, which includes a rotating shaft and an air cylinder installed on the lower end surface of the mold box mounting plate. The second bearing is connected; the rotating shaft sleeve is connected with one end of the swing arm and one end of the connecting rod respectively, the other end of the swing arm is connected with the guide roller shaft, and the guide roller is set on the guide roller shaft through the first bearing sleeve, and the other end of the connecting rod One end is rotationally connected with the Y-shaped joint, and the Y-shaped joint is connected with the piston rod of the cylinder. A cam is installed on the rotating shaft sleeve, and a displacement sensor is installed on one side of the cam. The connecting rod is connected with the connecting rod through the first pin shaft. The invention avoids the phenomenon that the tuning roller does not rotate well, and avoids the frequent jamming of the tuning shaft of the wire drawing unit and the serious deformation of the shaft to damage the equipment, and improves the equipment start-up rate and product yield rate.

Description

technical field [0001] The invention relates to a tuning device, in particular to a mold box tuning roller device on a straight wire drawing machine. Background technique [0002] The straight wire drawing unit used for continuous drawing of steel wire is composed of multiple drawing units. The tuning roller device is the key device to sense the change of tension to coordinate the speed of each drawing unit. The wire drawing machine with the traditional tuning roller structure has been used for a short time. The tuning stick just has the phenomenon that the swing arm does not rotate properly, causing the steel wire to loosen or mess up and be pulled off. After one year of use, such failures occurred frequently. After the shaft was removed, it was found that the surface of the shaft and the oil on the surface were covered with dust, which affected the rotation of the shaft; If it is larger, it will also cause the shaft to jam. According to the experience of dismantling the...

[0002] The straight wire drawing unit used for continuous drawing of steel wire is composed of multiple drawing units. The tuning roller device is the key device to sense the change of tension to coordinate the speed of each drawing unit. The wire drawing machine with the traditional tuning roller structure has been used for a short time. The tuning rod will have a phenomenon that the swing arm does not rotate properly, causing the steel wire to be loose or messy and broken

After one year of use, such failures occurred frequently. After the shaft was removed, it was found that the surface of the shaft and the oil on the surface were covered with dust, which affected the rotation of the shaft; Larger, will also cause shaft jamming

According to the experience of dismantling the faulty tuning roller device for many times, analyzing various fault phenomena, it is found that the structure of this type of device has the following problems: (1) There is no axial positioning of the rotating shaft, and the gap between the swing arm and the rotating sleeve is difficult Guaranteed, the gap often changes when the equipment is running, so that the swing arm is jammed; (2) The tuning roller shaft is installed at the front end of the mold box, and the wire drawing powder in the mold box is easy to accumulate on the shaft sleeve, and the dust passes through the swing arm and rotates The gap between the shaft sleeves enters the oil groove of the shaft, so that the grease cannot be injected, and finally fouling is formed, which makes the rotation of the shaft in the copper sleeve inflexible, so that the swing arm is jammed; (3) The size of the shaft is too small, the strength is poor, Easy to deform and bend, affecting the free rotation of the shaft
