Description

Binding wire cutting machine

technical field

The utility model relates to a binding wire cutting machine. the

Background technique

The skeleton of building columns and beams is steel bars, and the bearing capacity of columns and beams is closely related to the rational distribution of internal steel bars and then fixed. The fixing method is to use 18#-22# low-carbon steel wires to bind them. The length of the binding wire is determined by the thickness of the steel bar. There are six types of specifications: 200, 250, 300, 350, 400, and 450 mm. They are cut from low-carbon steel wires with large bundles of pan heads. The cutting method of binding wire on the construction site has always been the old method, that is: from the large bundle of low-carbon steel wire raw materials, randomly take out 100-200 coils of wire, and use the old-fashioned gadolinium knife to cut along the circumferential direction. Obtain segment wires; there are also some construction sites that even use a grinding wheel cutting machine to cut segments along the circumference, and the cutting operation process is very unsafe. The common problems of these backward feeding methods are as follows: first, it is very easy to wind and disorder when taking small strands from a large bundle of coils, and it takes time and material to strip off the messy strands; second, the small strands are along the circumferential direction The cutting is divided by visual inspection, and the lengths of the divided cuts are different. When binding, the length of the wire is not enough to be directly discarded. The 3rd, steel bar binding workers often intentionally divide and cut according to the long specification size to facilitate the binding of both thick and thin steel bars in order to reduce the troubles caused by splitting and cutting multiple specifications, which causes waste of materials artificially. For a building, although steel bar binding wire is a small material, the amount used by the entire construction industry is considerable, causing waste and safety hazards that cannot be underestimated. the

1. Working process of fixed-length feeding transmission route

The output shaft 01 is connected with the incomplete gear 5, and the first gear 7 meshed with it realizes clearance movement, and the right end of the first coupling shaft 02 of the first gear 7 has a second gear 9 which meshes with the third gear 11 with the same number of teeth, thereby Realize that the first shaft coupling shaft 02 and the second coupling shaft 03 rotate at the same speed and stop alternately, and also make a pair of wire feed rollers 13 with equal diameters located at the left ends of the first shaft coupling shaft 02 and the second coupling shaft 03, The wire feed rollers 17 realize synchronous constant speed rotation and stop operation, and as a result, the steel wire sandwiched between the two wire feed rollers completes the fixed-length feeding under the action of friction.
