Abstract
The present invention relates to a device for automatically bending both ends of a plastic plating steel wire. A positioning strip is arranged on a machine body of the device; two fixed center pins and the positioning strip are formed into a whole; eccentric pins are respectively arranged on two circular disks; a pressing strip is arranged on an eccentric pin shaft; the center of each circular disk is positioned eccentrically with each center pin; and the pressing strip does not make linear movement correspondingly to the eccentric pins in the process of bending steel wires. A motor drives the circular disks to rotate; a plastic plating steel wire bends and deforms by the pressing strip on each eccentric pin shaft; after both ends are bended, the motor rotates reversely, and the pressing strip retracts to the original position. In the whole process, both ends of the steel wire are simultaneously bended by a hydraulic pressure or pneumatic system. The bending angle is regulated by regulating screws. The device can automatically bend both ends of the plastic plating steel wire into required angles, and the plastic plating layer is not damaged.
Description
Technical field
The present invention relates to a kind of device for automatic bending head of steel wire with plastic plated that steel wire with plastic plated two can be bent to automatically required different angles simultaneously.
Background technology
Be different from the bending of general steel wire for the elbow of steel wire with plastic plated, it often not only needs two is bent to required angle, and requires in crooked steel wire, does not destroy plating and moulds layer.General bend pipe or elbow equipment because bending point force localization or application point move on steel wire, will destroy plating and mould layer, therefore, at present, also be in for the steel wire with plastic plated elbow and manually to reach single elbow and carry out, and labor strength is big, and efficient is low.
Summary of the invention
The purpose of this invention is to provide and a kind of steel wire with plastic plated two can simultaneously be bent to required different angles automatically, do not destroy the device for automatic bending head of steel wire with plastic plated that layer is moulded in plating.
The object of the present invention is achieved like this: this device is equipped with body and a positioning strip of laying steel wire with plastic plated to be curved, positioning strip two respectively is equipped with a fixing centrepin, disk reaches and from disc centre off-centre cylindrical pin is installed, the press strip that can rotate around it is housed on this cylindrical pin, be equipped with a baffle plate on the body, be equipped with an adjustment screw on the baffle plate, disc centre and centrepin center are respectively arranged with the eccentric throw of level and vertical two directions, and disk is connected with rotary actuator.During work, press strip passes through the press strip crooked steel wire by behind the last steel wire by the straight pin that is installed in from disc centre off-centre on the disk.After bending puts in place, drive disk, press strip by rotary actuator, and under the guiding of baffle plate, return original position.
Mould layer for further protection plating and be not destroyed, have the half-arc groove that is harmonious with steel wire on press strip and the plane that steel wire with plastic plated contacts.In order to make smoothly reposition of press strip, the eccentric throw between disc centre and centrepin should make in the whole BENDING PROCESS, by being installed in cylindrical pin on the disk from disc centre off-centre in the disk rotation process, does not have straight line to move relative to press strip.The angle of the required rotation of BENDING PROCESS can be regulated by adjustment screw.
The present invention is owing to adopted the press strip that is contained on the eccentric straight pin of installing; by rotary actuator driver plate, eccentric cylindrical pin, the press strip of installing; make steel wire with plastic plated flexural deformation; owing to do not relatively move between press strip and the steel wire; press strip has disperseed the concentrated active force of the cylindrical pin of eccentric installation again; having protected the steel wire plating to mould under the prerequisite of layer effectively, realized the elbow technology at steel wire with plastic plated two.Because disc centre of the present invention is that cylindrical pin relative press strip in whole elbow process of eccentric installation is not relatively moved with eccentric throw between the eccentric cylindrical pin of installing, thereby has simplified the back body of press strip greatly.Elbow finishes, control rotary actuator backward rotation, and press strip just can be followed disk, by the guiding of baffle plate, returns original position easily.Whole process can make steel wire two finish elbow technology simultaneously automatically by hydraulic pressure or pneumatic system.Angle of bend also can be regulated arbitrarily easily by adjustment screw.
