Description

Technical Field

[0001] The utility model relates to the technical field of contact wire processing, in particular to a drawing device for rigid contact wire production. Background Art

[0002] A rigid contact wire is a special electrical conductor, commonly used in contact lines in power supply systems. Unlike traditional flexible conductors, rigid contact wires are made of hard metal materials and have higher strength and rigidity. Rigid contact wires are usually used in high-voltage lines in transmission and distribution systems, such as power lines, railway electrification systems, etc. Its main function is to transmit electrical energy from power stations or substations to various users or equipment.

[0003] By comparing a silver-plated copper wire continuous drawing production machine with patent announcement number CN220406664U, in this scheme, the tension applied to the slider by the elastic member enables the limit rod to be retracted toward the center of the positioning frame, which is beneficial to clamp and limit the edge of the wire during the unwinding process, and avoid the wire from loosening and becoming scattered during unwinding. However, when this device pulls the wire, a large friction force will be formed between the wire and the drawing mechanism to cause the wire to deform to complete the drawing operation, so that the wire may leave a certain amount of waste on the inner wall of the drawing mechanism while being pulled. After a long period of accumulation, these wastes will adhere to the inner wall of the drawing mechanism, which is not conducive to cleaning the stains on the inner wall of the drawing mechanism, and the drawing mechanism needs to be replaced frequently, which may reduce the drawing quality of the wire.

Before drawing the contact wire, the lubrication assembly is used to lubricate the surface of the contact wire to reduce the damage to the surface of the contact wire caused by the friction between the contact wire and the drawing die 209. After the drawing die 209 is used for a long time, residual waste chips may adhere to the inner wall of the drawing die 209. Then, the cleaning assembly is used to comprehensively clean the waste chips on the inner wall of the drawing die 209, reduce the adhesion of waste chips on the inner wall of the drawing die 209, reduce the frequent replacement of the drawing die 209, and prevent the residual waste chips from affecting the drawing of the contact wire, thereby improving the quality of the contact wire drawing.

[0035] Working principle: First, drive the guide motor 303 to drive the guide roller 302 to rotate, and drive the conveying motor 306 to drive the conveying roller 305 to rotate. The contact wire to be processed is sequentially passed over the guide roller 302 and the conveying roller 305, then passes through the oil storage chamber 211 and the drawing die 209, and then the drawing die 209 is used to perform a drawing operation on the contact wire. Rotate the rotary handle to drive the bidirectional threaded rod 208 to rotate, and drive the two clamping plates 207 to move away from each other, so that the drawing die 209 can be replaced to adapt to the processing of different types of contact wires.

[0036] Before drawing the contact wire, drive the oil pump 213 to transport the lubricating oil in the oil storage cavity 212 into the oil storage chamber 211, and use the plurality of oil outlet holes on the inner wall of the oil storage chamber 211 to evenly apply the lubricating oil on the surface of the contact wire, so as to reduce the friction between the contact wire and the drawing die 209 when the contact wire contacts the drawing die 209 and reduce the damage to the surface of the contact wire. Secondly, drive the lifting motor 203 to drive the lifting lead screw 202 to rotate, drive the lifting plate 204 to move up and down, and then drive a plurality of drawing dies 209 to move up and down, so as to better reduce the stress generated when the contact wire is drawn and reduce the damage to the contact wire.

[0037] After the drawing operation is completed, the driving adjustment motor 228 drives the adjustment lead screw 216 to rotate, driving the slide rail 217 to move. Then, the driving movement motor 218 drives the movement lead screw 219 to rotate, driving the movement seat 220 to move back and forth within the slide rail 217, thereby driving the brush bar 227 above the movement seat 220 to move back and forth. Then, the air cylinder 221 is driven to drive the lifting seat 222 to move upward, moving the brush bar 227 to the center of the drawing die 209, making the brush bar 227 coaxial with the drawing die 209. Subsequently, the brush bar 227 is inserted into the drawing die 209, and the driving rotation motor 223 drives the dust suction box 224 and the brush bar 227 to rotate, enabling the brush bar 227 to clean the waste chips remaining on the inner wall of the drawing die 209. At the same time, the dust suction fan 225 inside the dust suction box 224 is driven to rotate, and the cleaned waste chips are sucked into the filter screen 226 inside the dust suction box 224 through multiple suction holes on the surface of the brush bar 227, enabling the filter screen 226 to filter and collect the waste chips, thereby completing the cleaning work of the waste chips in the drawing die 209, reducing the adhesion of waste chips to the inner wall of the drawing die 209, reducing the frequent replacement of the drawing die 209, preventing the remaining waste chips from affecting the drawing of the contact wire, and improving the quality of the contact wire drawing.
