Description

Technical Field

[0002] The non-slip wire drawing machine is used to draw various fine wires. Since there is no slip between the drive wheel and the wire, the surface quality of the drawn wire is good. The drawing of the wire of the non-slip wire drawing machine is controlled by the swing of the tension swing rod, so that each independent drive wheel is strictly synchronized with the drawing speed. It is not easy to produce sliding friction between the wire and the drive wheel, and non-slip drawing is achieved; non-slip drawing makes the stress of the wire uniform when it is shaped and deformed, which can inhibit scratches or breakage on the wire surface, and can run at high speed. The non-slip wire drawing machine is specially used for drawing fine wires, with the characteristics of high surface quality and low tension.

[0019] The wire drawing unit includes N wire drawing units, each of which includes a wire drawing eye die unit, a driving unit and a tension control unit. In the prior art, the wire drawing eye die unit, the driving unit and the tension control unit in each wire drawing unit are centrally arranged to form a whole. Figure 1 As shown. In the present patent application, the wire drawing eye die parts 701 in each wire drawing unit are concentrated together and sequentially arranged in the eye die seat 7 along the direction from back to front. The eye die seat 7 is fixed on the body 1 of the non-slip wire drawing machine. The driving part and the tension control part in each wire drawing unit are centrally arranged to form a subunit 9. N subunits 9 are divided into M groups, M is a positive integer, and M groups of subunits 9 are arranged on the body 1 along the direction from top to bottom. Each subunit 9 in each group is sequentially arranged on the body 1 along the direction from left to right. In the present embodiment, M is 2.

[0020] The driving part in each subunit 9 includes a driving wheel 901 and a wire-dividing follower wheel 902, which are respectively arranged on the machine body 1 via a connecting shaft. After the wire passes around the driving wheel 901 and the wire-dividing follower wheel 902, the wire coming out of the driving wheel 901 is wound around the tension control part, which includes a second swing rod and a second tension wire wheel 904. The wire coming out of the driving wheel 901 is wound around the second tension wire wheel 904. The structure of the tension control part is the same as that of the tension control part in the non-slip wire drawing machine in the prior art, and will not be described in detail here.

[0021] Among the two adjacent sub-units 9 in each group, the sub-unit 9 on the right side protrudes forward by a preset distance compared to the sub-unit 9 on the left side, so that the positions of each sub-unit 9 in each group along the front-to-back direction correspond one-to-one with the positions of each corresponding wire drawing eye mold part 701 in the eye mold seat 7 along the front-to-back direction; and among the two adjacent groups of sub-units 9 above and below, the leftmost sub-unit 9 in the lower group of sub-units 9 protrudes forward by a preset distance compared to the rightmost sub-unit 9 in the upper group of sub-units 9, and the positions of these two sub-units 9 along the front-to-back direction correspond one-to-one with the positions of the two corresponding wire drawing eye mold parts 701 in the eye mold seat 7 along the front-to-back direction.

After the wire bypasses the driving wheel 901 and the wire dividing wheel 902, the wire coming out of the driving wheel 901 is wound around the second tension wire wheel 904 of the tension control section. After that, the wire passes through the corresponding wire wheels in each wire wheel group (for example, the corresponding wire wheels in the third wire wheel group 10 and the fourth wire wheel group 11) in turn, and then is wound around the next wire wheel in the first wire wheel group 6.
