Description

Technical Field

[0001] The invention belongs to the technical field of wire drawing machines, and in particular relates to a water tank type wire drawing machine. Background Art

[0002] Wire drawing machines are widely used in industrial applications, and are widely used in machinery manufacturing, hardware processing, petrochemicals, plastics, bamboo and wood products, wire and cable and other industries. In the nail making process, the existing nail making tower wheel wire drawing process mostly uses a wire drawing device with a low-speed tower wheel and a high-speed tower wheel installed on the same shaft. During the working process of the wire drawing machine, its drawing synchronization performance is poor, the equipment wear rate is high, the equipment is easy to be damaged, and its drawing process consumes a lot of wire energy. During the drawing process, the wire is prone to surface abrasion, wire breakage and wire jump, which ultimately causes the problem of poor quality of the finished wire.

[0003] The Chinese invention patent with announcement number CN109940118A discloses a four-sided double-wrap wire drawing machine, and its process flow is as follows: the metal wire raw material wire to be drawn is introduced into the low-speed drawing tower wheel group through the wire drawing die, passes through the low-speed winding tower wheel group, and then passes through the die on the die bracket and is introduced into the low-speed drawing tower wheel group. The wire is thinned according to a certain diameter reduction rate, and after multiple reciprocating drawing, the drawing process of the inner wrapping tower wheel group is completed, and then the wire is introduced into the outer wrapping tower wheel group, and the reciprocating drawing continues to be performed to the required wire specification, and then enters the wire taking-up process through the traction wheel, and the drawing production process is completed. This process realizes that each group of tower wheels is individually wrapped, the high and low speed winding shafts are driven separately, and the wire speed difference is automatically adjusted, which reduces the transmission resistance, reduces the drawing power consumption, and realizes high-precision transmission of the equipment, saves the equipment manufacturing cost and the equipment production and operation cost, and is not prone to wire breakage during operation, thereby improving product quality and work efficiency.

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] like Figure 1-2 As shown, a water tank type wire drawing machine includes a motor 1, a tower pulley shaft A2, a tower pulley shaft B3, a tower pulley shaft 2 4, and a tower pulley shaft 3 5.

[0020] The step pulley shaft A2 is a hollow shaft, and the step pulley shaft B3 passes through the step pulley shaft A2. The output shaft of the motor 1 is fixedly provided with a motor pulley 6, the step pulley shaft A2 is fixedly provided with a step pulley shaft A pulley 7, the step pulley shaft B3 is fixedly provided with a step pulley shaft B small pulley 8, the step pulley shaft 2 4 is fixedly provided with a step pulley shaft 2 pulley 1 9, a step pulley shaft 2 large pulley 2 10, and a step pulley shaft 2 synchronous large pulley 3 11, and the step pulley shaft 3 5 is fixedly provided with a step pulley shaft 3 synchronous small pulley 12 and a step pulley shaft 3 pulley 2 13.

[0021] The motor pulley 6 is connected to the pulley 2 10 of the tower wheel shaft three through a transmission belt, the synchronous small pulley 12 of the tower wheel shaft three is connected to the synchronous large pulley 3 11 of the tower wheel shaft two through a transmission belt, the large pulley 2 10 of the tower wheel shaft two is connected to the small pulley 8 of the tower wheel shaft one B through a transmission belt, and the pulley 1 9 of the tower wheel shaft two and the pulley 7 of the tower wheel shaft one A are connected through a transmission belt.

[0022] The pulley shaft A2 is fixedly provided with a low-speed winding pulley 14, and the pulley shaft 2 4 is fixedly provided with a low-speed drawing pulley 15 corresponding to the low-speed winding pulley 14; the pulley shaft B3 is fixedly provided with a high-speed winding pulley 16, and the pulley shaft 3 5 is fixedly provided with a high-speed drawing pulley 17 corresponding to the high-speed winding pulley 16. The water tank type wire drawing machine includes a water tank, and the low-speed winding pulley 14, the low-speed drawing pulley 15, the high-speed winding pulley 16, and the high-speed drawing pulley 17 are all arranged in the water tank.

[0023] The circumferential rotational speeds of the corresponding parts of the low-speed winding tower wheel 14 and the low-speed drawing tower wheel 16 are the same; the circumferential rotational speeds of the corresponding parts of the high-speed winding tower wheel 16 and the high-speed drawing tower wheel 17 are the same.

[0024] After the motor 1 is started, the raw wire enters the low-speed drawing tower wheel through the drawing die, and then passes through the low-speed winding tower wheel 14, enters the die bracket, and enters the low-speed drawing tower wheel 15 through the die of the die bracket, so that the introduced raw wire is reciprocated and drawn between the low-speed drawing tower wheel 15 and the low-speed winding tower wheel 14; when the raw wire is stretched around the tower wheel group at low speed, it enters the high-speed winding tower wheel 16, and then passes through the die of the die bracket into the high-speed drawing tower wheel 17, and the raw wire is reciprocated and drawn between the high-speed winding tower wheel 16 and the high-speed drawing tower wheel 17, and the finished wire after drawing enters the wire take-up machine.

[0025] In order to ensure that the gap between the step pulley shaft A2 and the step pulley shaft B3 can be well sealed and prevent the water in the water tank from entering the transmission box, a rotating seal structure needs to be set between the step pulley shaft A2 and the step pulley shaft B3. Figure 3 As shown, in this embodiment, the rotary seal structure is as follows:

[0026] A bearing 18, a slip ring mounting seat 19, a slip ring 20 and a slip ring fixing ring 21 are provided inside one end of the pulley shaft A2 located in the water tank; a step portion for positioning the bearing 18 is provided inside the pulley shaft A2, and one end of the bearing 18 rests on the step portion; the slip ring mounting seat 19 is fixedly arranged on the pulley shaft A2 by a locating pin, and the other end of the bearing 18 rests on the slip ring mounting seat 19; the slip ring 20 is fixedly mounted on the pulley shaft B3 by the slip ring fixing ring 21, and the slip ring 20 is rotatably matched with the slip ring mounting seat 19; sealing rings are provided at the contact surfaces of the slip ring mounting seat 19 and the pulley shaft A2, and at the contact surfaces of the slip ring 20 and the slip ring mounting seat 19.

[0027] In this embodiment, the bearing 18 and the low-speed winding tower wheel 14 are installed at the same position of the tower wheel shaft A2. Since the tower wheel shaft A2 is a hollow shaft with low structural strength, the low-speed winding tower wheel 14 is installed on the tower wheel shaft A2 to increase the structural strength of the tower wheel shaft A2 at this location. The bearing 18 is installed inside the tower wheel shaft A2 at this location to better support the tower wheel shaft B3; and because the structural strength of the tower wheel shaft A2 at this location is increased, the tower wheel shaft A2 is not easily deformed, and the wear of the bearing 18 is reduced.

[0028] In addition to the above preferred embodiments, the present invention has other implementation modes. Those skilled in the art may make various changes and modifications based on the present invention. As long as they do not depart from the spirit of the present invention, they should all fall within the scope defined by the claims attached to the present invention.
