Description

Coiled material compressing device Technical Field The utility model relates to the technical field of manufacturing of cold heading forming machines, in particular to a coiled material compacting device. Background The cold heading forming machine is forging forming equipment for thickening the top of a bar or a coiled material at room temperature, and is special equipment mainly used for mass production of fasteners such as nut bolts and the like. Specifically, the cold heading forming machine drives curled steel into a machine body of the cold heading machine through a feeding mechanism, shears the curled steel into a plurality of sections through a shearing mechanism, heading the steel sections through a heading mechanism, and performs the working procedures of forming, chamfering, thread rolling, diameter reducing, trimming and the like, and the steel sections are processed into products such as screws, bolts and the like. In the cold heading forming machine, coiled metal wires are usually selected, and coiled materials are bound and fixed by steel wire ropes or binding belts, but when the binding belts or the steel wire ropes are cut off, the coiled materials rebound and instantly spring open, so that the cold heading forming machine is dangerous. Especially in the case of large machines, heavy injuries to the operator can also occur. In order to perform the operation safely, the market needs a set of coil pressing devices. Disclosure of Invention The utility model aims to provide a coiled material compressing device which solves the problems in the prior art. The coiled material compressing device is applied to a cold heading forming machine and is characterized by comprising a bottom beam of the cold heading forming machine, wherein a first base, a second base and a third base are arranged on the bottom beam, a hydraulic transmission unit is rotatably fixed on the first base, a first connecting rod is hinged on the second base, a connecting rod sliding sleeve with an inner cavity is hinged on the head of the other end of the first connecting rod, a compression rod is hinged on the third base, the compression rod penetrates through the inner cavity of the connecting rod sliding sleeve, a connector is arranged at the front end of a piston rod of the hydraulic transmission unit, and the connector is hinged with the first connecting rod. Compared with the prior art, the utility model has the advantages that the pressing rod can press the bound coiled material through the pulling of the hydraulic transmission unit, and after the binding belt is unwound, the coiled material can be blocked by the pressing rod when being ejected, so that the injury to operators can be avoided. As an improvement of the utility model, the position of the joint of the connecting head and the first connecting rod is at least within half of the whole length of the first connecting rod close to the second base side. The design is selected to ensure that a connector on a piston rod of the hydraulic transmission unit pulls the first connecting rod, and the connecting rod sliding sleeve with the first connecting rod can drive the pressure rod to enlarge the swing amplitude of the pressure rod although the power arm is smaller than the resistance arm. As an improvement of the utility model, the hydraulic transmission unit is a tail-swing type cylinder. The tail-swing type cylinder has the advantages that the tail-swing type cylinder can rotate in a certain amplitude through the hinge device at the tail part, so that the piston rod swings in a small amplitude, and the connecting rod mechanism can run smoothly. As an improvement of the utility model, a linear bearing is arranged in the connecting rod sliding sleeve. The design is selected to ensure that the linear bearing is in point-to-point friction, the friction force is smaller, and the movement of the compression bar in the connecting rod sliding sleeve is smoother. As an improvement of the utility model, the first base and the second base are arranged on the side face of the bottom beam, and the third base is arranged on the front face of the bottom beam. The design is selected so that the first base and the second base are staggered from the plane of the third base, and the parts cannot interfere with each other.
