Abstract
First guide pipes are disposed on both sides of blasting areas, and second guide pipes are disposed on both sides of the blasting area. A wire rod W is inserted through the first guide pipes and the second guide pipes, penetrating in a conveying direction of the wire rod W. The diameter of each of first insertion holes of the first guide pipes and second insertion holes of the second guide pipes is gradually reduced toward the downstream side in the conveying direction. The second guide pipe is installed in a state in which the downstream-side end portion in the conveying direction is inserted into the first insertion hole from the inlet side of the first guide pipe.
Claims15
A shot processing device comprising:
- a blasting device configured to blast shot media onto a wire rod which is an object to be processed and conveyed in a predetermined conveying direction;
- a cabinet including a blasting area in which the wire rod is surface-processed by the shot media blasted by the blasting device, the blasting area being provided inside of the cabinet;
- first guide pipes disposed on both sides of the blasting area, respectively, each of the first guide pipes having a first insertion hole formed to penetrate in the conveying direction of the wire rod and through which the wire rod is inserted, the first insertion hole having a diameter gradually reduced toward a downstream side in the conveying direction;
- and
- a second guide pipe disposed on at least one of both sides of the blasting area and having a second insertion hole formed to penetrate in the conveying direction of the wire rod and through which the wire rod is inserted, the second insertion hole having a diameter gradually reduced toward the downstream side in the conveying direction, the second guide pipe being installed in a state in which a downstream-side end portion in the conveying direction is inserted into the first insertion hole from an inlet side of the first guide pipe,
- wherein a gap for shot media passage is set at least in a part between a portion of the second guide pipe disposed inside the first guide pipe and an inner surface of the first guide pipe.
