Description

[Detailed description of the device]

[0001]

[Industrial applications]

 In the present invention, in the process of continuously drawing / drawing a wire rod, it is arranged in the vicinity of, for example, a butt welding machine that press-contacts the rear end of the front-stage wire rod and the front end of the rear-stage wire rod. It relates to a device for removing.

[0002]

[Prior art]

 For example, in the process of continuously drawing and drawing a wire rod, the coil unwound from the pay-off reel is straightened by a straightening machine, and then the tip of the coil is butt welded to the rear end of the preceding wire rod. It is pressed and continuously supplied to the drawing machine for drawing.

By the way, a flash 2 is generated at the pressure contact portion between the rear end of the front-stage wire rod 1a and the front end of the rear-stage wire rod 1b, as shown in FIG. Since this flash interferes with the drawing work in the subsequent process, it has to be removed in advance, but in the past, all this flash removal work relied on manual work by an operator using a hand grinder, and heavy work under dust. It was typical of muscle work.

[Action]

 In the deburring device of the wire rod pressure contact portion of the present invention, the clamp mechanism clamps the upstream and downstream sides of the pressure contact portion between the front end of the front wire rod and the front end of the rear wire rod, and then the shift mechanism is driven to drive the wire rod and the cutting blade. If the positions of the holes on the cutting edge are matched, and then the tuning rotation mechanism is driven to rotate the pair of cutting blades at a predetermined angle in synchronization, the holes formed on the pair of cutting blades generate the pressure contact portion. The shavings will be scraped off and can be removed. Further, when a plurality of the hole types provided in the pair of cutting blades are provided so as to correspond to different wire rod diameters, the shift mechanism is driven to change the wire rod and the wire rod when the diameter of the wire rod changes. The burrs of the press contact portion are removed in the same manner as described above by matching the hole type corresponding to the diameter.
