Description

Technical Field

[0001] This application relates to the field of wire drawing machine design, and more specifically, to a wire drawing machine with a long die life. Background Technology

[0002] A sliding continuous wire drawing machine generates friction because the circumferential speed of the drum exceeds the wire drawing speed. Common sliding continuous wire drawing machines use emulsion or liquid oil lubricants. The lubricant is contained in the processing tank of the drawing machine, and the drum, wire segment, and die are all immersed in the lubricant. The structure is simple and can ensure continuous lubrication and cooling of the die, drum, and wire.

[0003] However, its disadvantages are: the metal shavings generated during the wire drawing process are constantly agitated by the drum and have no chance of settling. They are continuously carried into the die hole, and the surface of the die hole usually requires a high degree of surface smoothness and is expensive. Long-term friction with metal shavings causes scratches on the die hole, reducing the service life of the wire die and requiring frequent replacement of the wire die, which increases production costs. Summary of the Invention

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section above, some embodiments of this application provide a wire drawing machine with a long die life, comprising: a processing groove; two sets of drums, the two sets of drums being placed in the processing groove and rotating in the same direction; a support frame, placed in the processing groove and located between the two sets of drums, the support frame forming a connected mounting groove and a long groove sequentially from one end facing one set of drums to the other end facing the other set of drums, the width of the long groove being smaller than the width of the mounting groove; and a wire die, placed in the mounting groove and forming a die hole communicating with the long groove.

[0006] Furthermore, it also includes: a filter block; the filter block is installed in the long groove, the filter block forms a through hole, one port of the through hole points to a group of drums, the other port of the through hole communicates with the mold hole of the wire mold, and the diameter of the through hole is 1-2 mm larger than the diameter of the mold hole.

[0007] Furthermore, the through hole includes a chamfered hole section and a straight hole section, with the port of the chamfered hole section facing the drum wheel and the port of the straight hole section communicating with the mold hole.

[0008] Furthermore, the upper end of the filter block forms a discharge groove, and the lower end of the discharge groove is connected to the chamfered hole section.

[0009] Furthermore, annular bristles are provided in the straight section of the through hole, and the side of the annular bristles facing the chamfered section is connected to the lower end of the discharge groove.

[0010] Furthermore, the surface of the filter block forms a protrusion extending radially along the through hole, and the support frame also forms a limiting groove, one end of which communicates with the long groove, and the protrusion is inserted into the limiting groove.

[0011] Furthermore, it also includes: a motor; the motor is provided in two sets, and the output ends of the two sets of motors are connected to the drum in a one-to-one correspondence, so that the two sets of drums rotate in the same direction.

[0012] The beneficial effects of this application are as follows:

[0013] The wire segment is driven by the drum to enter the long groove first. The long groove is narrow, and most of the lubricant around the wire segment is blocked in the processing groove by the end of the long groove. The metal chips are also blocked in the processing groove. Then the wire segment enters the wire mold in the installation groove for stretching, which reduces the friction of metal chips on the mold hole, reduces the frequency of wire mold replacement, and saves production costs.

[0029] Reference Figure 1-5 ,

[0030] A wire drawing machine with a long wire drawing die 4 includes: a processing groove 1, drums 2, a support frame 3, and a wire drawing die 4. The processing groove 1 contains an emulsion-like lubricant with high viscosity. Two drums 2 are arranged parallel to each other in the processing groove 1 and rotatably connected to the side wall of the processing groove 1. The drums 2 are used to pull wire segments. The support frame 3 is placed in the processing groove 1 and fixed to the side wall of the processing groove 1 by bolts. The support frame 3 is located between the two drums 2, and the support frame 3 forms mounting grooves 5 and long grooves 6 sequentially from one end of the support frame 3 towards one set of drums 2 to the other end towards the other set of drums 2. Multiple sets of mounting grooves 5 and long grooves 6 are provided. The mounting grooves 5 and long grooves 6 are connected along the direction of wire segment pulling. The shape of the mounting groove 5 matches the contour of the wire drawing die 4. The wire drawing die 4 is placed in the mounting groove 5, and a die hole for compressing the wire segment is formed in the middle of the wire drawing die 4. The wire segment is driven by the drum 2 and first enters the long groove 6. Since the width of the long groove 6 is smaller than the width of the mounting groove 5, the end of the long groove 6 will block most of the lubricant and metal shavings outside the support frame 3. Then the wire segment will carry a small amount of lubricant attached to itself through the wire mold 4 located in the mounting groove 5. At this time, there are also fewer metal shavings attached to the wire segment, and the friction of the wire segment on the mold hole is reduced when it passes through the mold hole.

[0031] In another embodiment, a filter block 7 is also included. The filter block 7 is installed in the long groove 6 in conjunction with the long groove 6. The filter block 7 forms a through hole, one end of which points to a set of drums 2, and the other end of which communicates with the die hole of the wire mold 4. The through hole and the die hole are coaxial, and the diameter of the through hole is 1 mm larger than the diameter of the die hole. Some metal shavings rub against the long groove 6 for a long time under the drive of the wire segment, which can easily cause excessive wear of the long groove 6. By placing the filter block 7 in the long groove 6, the part that rubs against the metal shavings becomes the filter block 7. After the filter block 7 is excessively worn, only the filter block 7 needs to be replaced, without replacing the entire support frame 3, thus saving costs.

[0032] Specifically, the through-hole includes a chamfered section 8 and a straight section 9. The port of the chamfered section 8 faces the drum 2 that feeds the wire segment into the filter block 7, and the port of the straight section 9 connects to the mold hole. Because the lubricant has a high viscosity, it is difficult for the wire segment to directly enter the through-hole with its small diameter after the lubricant adheres to it. With the chamfered section 8, since the diameter of the chamfered section 8 decreases from large to small, the lubricant adhering to the wire segment is gradually squeezed off by the chamfered section 8 during the process of entering the through-hole, thus allowing the wire segment to smoothly enter the through-hole.

[0033] Specifically, the upper end of the filter block 7 forms a discharge groove 10, and the lower end of the discharge groove 10 is connected to the chamfered hole section 8. During the process of compressing lubricant, some lubricant may remain on the chamfered hole section 8, which can easily cause blockage of the through holes over time. With the discharge groove 10, the lubricant subsequently compressed onto the chamfered hole section 8 will push the previously accumulated lubricant upwards along the discharge groove 10 until it detaches from the upper end of the filter block 7, reducing the probability of lubricant clogging the through holes.

[0034] Specifically, annular bristles 11 are provided in the straight hole section 9 of the through hole, and the annular bristles 11 are glued and fixed to the inner wall of the straight hole section 9. The side of the annular bristles 11 facing the chamfered hole section 8 is connected to the lower end of the discharge groove 10, and the annular bristles 11 directly contact the surface of the line segment entering the through hole, preventing excess lubricant on the discharge groove 10 from falling downward and being carried into the straight hole section 9 by the line segment.

[0035] Specifically, the surface of the filter block 7 forms a protrusion 12 extending radially along the through hole. The support frame 3 also forms a limiting groove 13 that mates with the protrusion 12. One end of the limiting groove 13 communicates with the elongated groove 6. The protrusion 12 is inserted into the limiting groove 13 and engaged with it. When the line segment moves axially along the through hole, the lubricant adhering to the line segment will rub against the filter block 7, causing the filter block 7 to wobble on the support frame 3. The engagement of the protrusion 12 in the limiting groove 13 effectively reduces this wobble.

[0036] Specifically, it also includes: motors. Two sets of motors are provided, and both sets of motors are bolted to the processing groove 1. The two sets of motors are connected one-to-one to the drums 2, and the output ends of the motors are fixedly connected to the end of the processing groove 1 connected to the drums 2 via couplings. The two sets of motors cause the two sets of drums 2 to rotate in the same direction, thereby driving the line segment wound on the drums 2 to move towards the wire mold 4.
