Description

Technical Field

[0001] The invention relates to the technical field of copper rods, in particular to a wire drawing device for copper rods. Background Art

[0002] Copper rod is the raw material for the production of wires and cables.

[0003] According to the patent application number CN201922110686.0, the patent evenly sprays lubricant on the copper rod before entering the wire drawing shaping die, reducing the friction between the wire drawing shaping die and the copper rod wire drawing during the wire drawing process. The wire drawing shaping die is not easy to wear, the replacement frequency is low, and the service life is long, thereby reducing production costs and ensuring the smooth progress of wire drawing and the quality of copper rod wire drawing. The copper rod wire drawing can be cooled and cleaned in time when passing through the cooling mechanism, which improves the quality of copper rod wire drawing and ensures the smooth progress of subsequent processing. The above patent achieves the lubrication effect by adding several lubricant nozzles to spray lubricating oil on the surface of the copper rod. However, due to the large amount of lubricating oil sprayed, it is easy to drip to the outside world, which makes cleaning difficult and wastes lubricating oil. It is difficult to achieve the recycling of lubricating oil, which increases economic costs. Moreover, the device can only meet the production of copper wire of a single specification diameter, and it is difficult to adjust the copper wire diameter according to actual needs.

[0037] In an embodiment of the present invention, the bottom of the oil-absorbing sponge 48 passes through the through groove and extends to the inside of the through groove. There are two electric push rods 41 that are symmetrically arranged at the bottom of the inner wall of the collection frame 3. The protruding end of the electric push rod 41 is fixedly connected to the bottom of the surface of the U-shaped push rod 43.

[0038] In an embodiment of the present invention, the liquid inlet mechanism 5 includes a pressure pump 51 fixedly connected to the bottom of the inner wall of the collecting frame 3, an oil storage tank 52 is fixedly connected to the top of the top seat 2, and the front and back of the oil storage tank 52 are connected to an oil inlet pipe 53, and a sealing cover is provided on the top of the oil storage tank 52 to prevent dust from entering. The bottom end of the oil inlet pipe 53 passes through the top seat 2 and is connected to the top of the groove 42. An electromagnetic valve 54 is provided inside the oil inlet pipe 53, and the liquid outlet of the pressure pump 51 is connected to an oil outlet pipe 55 passing through the outside of the collecting frame 3. One end of the oil outlet pipe 55 is connected to one side of the surface of the oil storage tank 52, and a one-way valve is fixedly provided inside the oil outlet pipe 55.

[0043] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0044] When in use, lubricating oil is pre-stored in the oil storage tank 52, and the solenoid valve 54 is opened, so that an appropriate amount of lubricating oil in the oil storage tank 52 is transported to the inside of the groove 42 through the oil inlet pipe 53. At this time, the lubricating oil after entering the groove 42 is absorbed and stored by the oil-absorbing sponge 48, and the external traction device pulls and pulls the end of the copper rod (the traction device is an existing device and is not described in detail in this application document). When passing through the lubricating device, the electric push rod 41 is started, so that the protruding end of the electric push rod 41 drives the U-shaped push rod 43 to move upward along the surface of the support frame. At this time, the top of the U-shaped push rod 43 drives the upper movable seat 44 to push upward, and the upper movable seat 44 drives the buffer spring 45 to be compressed. At the same time, The semi-spherical block 411 can squeeze and push the toggle block 47, so that the two squeezing blocks 410 can squeeze the two sides of the oil-absorbing sponge 48, and the lubricating oil absorbed and stored in the oil-absorbing sponge 48 can be squeezed out to the upper surface of the copper rod through the through groove. The lubricating oil flows along the curved surface of the copper rod and flows into the arc-shaped oil-absorbing pad 7. The lubricating oil enters the lower surface of the copper rod for contact lubrication, thereby achieving uniform lubrication of the surface of the copper rod. During the process of squeezing out the lubricating oil, excess dripping lubricating oil flows into the collection frame 3 for collection and storage. The pressure pump 51 is started, so that the pressure pump 51 re-transports the excess oil in the collection frame 3 through the oil outlet pipe 55 to the oil storage tank 52 for recycling.

[0045] When the lubricated copper rod passes through the adjustment mechanism 1, the motor 12 is started, so that the motor 12 drives the rotating rod 13 to rotate, and then the rotating rod 13 drives the sleeve 15 to rotate, and the sleeve 15 drives the drawing plate 16 to rotate. There are four drawing plates 16, and the diameter specifications of the drawing holes 14 on each drawing plate 16 are different. According to the drawing requirements, the drawing plate 16 corresponding to the drawing hole 14 of the corresponding diameter can be rotated to be directly above, and the copper rod can be drawn into copper wire of the corresponding diameter.
