Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wire drawing machines, and in particular to a non-slip wire drawing machine for fine metal wires. Background Technology
[0002] Existing non-slip wire drawing machines typically include a wire feeding section, a wire drawing section, and a wire take-up section. The wire drawing section comprises several wire drawing units, each of which includes a wire drawing die, a drive unit, and a tension control unit. The tension control unit includes a swing arm. The wire drawing units of the wire drawing section are arranged sequentially from left to right.
[0003] The wire drawing die section includes a front guide roller, a wire drawing die, and a rear guide roller. The wire passes through the front guide roller, the wire drawing die, and the rear guide roller in sequence. Because it is difficult to keep the exit point of the front guide roller, the axis of the wire passage hole in the wire drawing die, and the entry point of the rear guide roller in a straight line, and because the force on the wire is very large during the drawing process, the inner wall of the wire passage hole in the wire drawing die will be worn by the wire during the drawing process. Furthermore, since the wire drawing die is stationary, a groove is usually worn radially at a certain position in the wire passage hole of the wire drawing die. This leads to the following problems:
[0004] 1) Reduces the lifespan of wire drawing dies and makes them difficult to repair;
[0005] 2) Reduces the surface quality of the finished wire after drawing;
[0006] 3) Increase the breakage rate of the wire;
[0007] 4) This results in poor straightness of the wire after drawing. Utility Model Content
[0008] In order to solve the problems existing in the prior art, this application proposes a non-slip wire drawing machine for fine metal wires, so that the wire drawing die can be rotated, thereby causing the wire to wear evenly on the inner wall of the wire drawing die's wire passage hole.
[0009] To achieve the above objectives, this application proposes a non-slip wire drawing machine for fine metal wires, including a wire feeding section, a wire drawing section, and a wire take-up section. The wire drawing section includes several wire drawing units, each of which includes a wire drawing die section, a driving section, and a tension control section. It also includes at least one wire drawing die seat drive rotation mechanism for driving the wire drawing die in the corresponding wire drawing die section to rotate about the axis of the wire passing hole of the wire drawing die.
[0010] In some embodiments, when only one wire drawing die holder drive rotation mechanism is included, the wire drawing die holder drive rotation mechanism is used to drive the wire drawing die in the wire drawing die part near the take-up part to rotate.
[0011] In some embodiments, the number of the wire drawing die holder drive rotation mechanism is the same as the number of the wire drawing unit, and the wire drawing die in each wire drawing die part can rotate under the action of the corresponding wire drawing die holder drive rotation mechanism.
[0012] In some embodiments, the structure of the wire drawing die holder drive rotation mechanism is as follows: it includes a first assembly plate, which is fixed on the body of the non-slip wire drawing machine. A motor is provided on the first assembly plate, which can drive a first synchronous pulley to rotate. The first synchronous pulley is connected to a second synchronous pulley via a synchronous belt. The second synchronous pulley is fixed at one end of the shaft of the wire drawing die holder in the corresponding wire drawing die part. When the motor is controlled to operate, it can drive the wire drawing die holder in the wire drawing die part to rotate, so that the wire drawing die assembled on the wire drawing die holder rotates.
[0013] In some embodiments, the wire drawing die part includes a mounting plate fixed to the machine body. A second assembly plate is fixedly provided on the front surface of the mounting plate, and the second assembly plate is perpendicular to the mounting plate. A cooling groove is fixedly provided on the left surface of the second assembly plate, and the cooling groove and the second assembly plate form an accommodating space with an open upper end. A first guide wheel shaft is provided on the mounting plate to the left of the cooling groove, and a front guide wheel is mounted on the first guide wheel shaft. A second guide wheel shaft is provided on the mounting plate to the right of the second assembly plate, and a rear guide wheel is mounted on the second guide wheel shaft. The wire drawing die of the wire drawing die part is located in the accommodating space, and the wire drawing die is mounted on the wire drawing die base. The wire passage hole of the wire drawing die is coaxially arranged with the wire routing hole of the wire drawing die base. The shaft of the wire drawing die base is rotatably connected to the second assembly plate through a bearing. The end of the shaft of the wire drawing die base is located on the right side of the second assembly plate, and a second synchronous pulley is connected to this end.
[0014] The beneficial effect of this application's solution is that the aforementioned non-slip wire drawing machine for fine metal wires is suitable for drawing wires with high requirements for straightness and surface quality. By setting a wire drawing die holder to drive the rotation mechanism, the wire drawing die can be rotated, thereby causing the wire to uniformly wear the inner wall of the wire drawing die's through hole. This gives the non-slip wire drawing machine for fine metal wires involved in this application the following advantages:
[0015] 1) It greatly extends the service life of wire drawing molds and makes them easy to repair;
[0016] 2) The finished wire has good surface quality after drawing;
[0017] 3) The wire breakage rate has decreased significantly;
[0018] 4) The finished wire has good straightness after drawing. Attached Figure Description

The terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0025] like Figures 1-3 As shown, the non-slip wire drawing machine for fine metal wires involved in this application includes a wire feeding section 1, a wire drawing section 2, and a wire take-up section 3. All three can be mounted on the machine body 4, or the wire drawing section 2 can be mounted on the machine body 4, while the wire feeding section 1 and the wire take-up section 3 are positioned at relevant locations as needed. The wire drawing section 2 includes several wire drawing units 21, each of which includes a wire drawing die section 211, a drive section 212, and a tension control section 213. The wire drawing units 21 of the wire drawing section 2 are arranged sequentially from left to right. This structure is the same as that of non-slip wire drawing machines in the prior art, and will not be described in detail here.
[0026] The non-slip wire drawing machine for fine metal wires involved in this application further includes at least one wire drawing die holder drive rotation mechanism 5. The wire drawing die holder drive rotation mechanism 5 is mounted on the machine body 4 and is used to drive the wire drawing die 2115 in the corresponding wire drawing die part 211 to rotate about the axis of the wire through hole of the wire drawing die 2115. When only one wire drawing die holder drive rotation mechanism 5 is included, the wire drawing die holder drive rotation mechanism 5 is used to drive the wire drawing die 2115 in the wire drawing die part 211 near the take-up part 3 to rotate.
[0027] To achieve the best results, in this embodiment, the number of wire drawing die holder drive rotation mechanism 5 is the same as the number of wire drawing units 21, that is, the wire drawing die 2115 in each wire drawing die part 211 can rotate under the action of the corresponding wire drawing die holder drive rotation mechanism 5.
[0028] In this embodiment, the structure of the wire drawing die holder drive rotation mechanism 5 is as follows: it includes a first assembly plate 51, which is fixed on the machine body 4. Specifically, it can be fixed on the rear surface of the support assembly plate of the machine body 4. Each wire drawing unit 21 is installed on the front surface of the support assembly plate of the machine body 4. A motor 52 is provided on the first assembly plate 51. The motor 52 can be a stepper motor, DC motor, etc. The motor 52 can drive the first synchronous pulley 53 to rotate. The first synchronous pulley 53 is connected to the second synchronous pulley 55 via a synchronous belt 54. The second synchronous pulley 55 is fixed at one end of the shaft of the wire drawing die holder 2114 in the corresponding wire drawing die part 211. When the motor 52 is controlled to move, it can drive the wire drawing die holder 2114 in the wire drawing die part 211 to rotate, so that the wire drawing die 2115 mounted on the wire drawing die holder 2114 rotates.
[0029] In this embodiment, the wire drawing die 211 includes a mounting plate 2111, which is fixed to the machine body 4. Specifically, it can be fixed to the front surface of the support assembly plate of the machine body 4. A second assembly plate 2112 is fixed to the front surface of the mounting plate 2111, and the second assembly plate 2112 is perpendicular to the mounting plate 2111. A cooling groove 2113 is fixed to the left surface of the second assembly plate 2112, and the cooling groove 2113 and the second assembly plate 2112 form an accommodating space with an open upper end. A first guide wheel shaft is provided on the mounting plate 2111 to the left of the cooling groove 2113, and a front guide wheel 2116 is mounted on the first guide wheel shaft. A second guide wheel shaft is provided on the mounting plate 2111 to the right of the second assembly plate 2112, and a rear guide wheel 2117 is mounted on the second guide wheel shaft. The structure of the wire drawing die 211 is similar to that of the prior art. The structure of the wire drawing die part 211 is similar and will not be described further here. In this embodiment, the wire drawing die 2115 of the wire drawing die part 211 is located in the receiving space, and the wire drawing die 2115 is mounted on the wire drawing die base 2114. The wire passing hole of the wire drawing die 2115 is coaxially arranged with the wire routing hole of the wire drawing die base 2114. A through hole is provided in the second mounting plate 2112, and a bearing is provided at the through hole. The inner ring of the bearing is connected to the shaft of the wire drawing die base 2114. That is, the shaft of the wire drawing die base 2114 is rotatably connected to the second mounting plate 2112 through the bearing. The end of the shaft of the wire drawing die base 2114 is located on the right side of the second mounting plate 2112, and a second synchronous pulley 55 is connected at this end. The synchronous belt 54 passes through the support mounting plate of the machine body 4 and the mounting hole provided on the corresponding mounting plate 2111 in sequence.
[0030] In practical use, the motor 52 can be controlled to rotate, thereby driving the shaft of the drawing eye die seat 2114 in the drawing eye die part 211 to rotate, which in turn causes the corresponding drawing eye die 2115 to rotate, so that the wire wears the inner wall of the wire passage hole of the drawing eye die 2115 evenly. The inner wall of the wire passage hole of the drawing eye die 2115 is worn evenly along the circumferential direction. Compared with the wear situation in the prior art, the wear degree of the wire passage hole of the drawing eye die 2115 along the radial direction is greatly reduced.
[0031] The non-slip wire drawing machine for fine metal wires involved in this application is suitable for drawing wires with high requirements for straightness and surface quality. By setting a wire drawing die holder to drive a rotating mechanism, the wire drawing die can be rotated, thereby causing the wire to uniformly wear the inner wall of the wire drawing die's through hole. This gives the non-slip wire drawing machine for fine metal wires involved in this application the following advantages:
[0032] 1) It greatly extends the service life of wire drawing molds and makes them easy to repair;
[0033] 2) The finished wire has good surface quality after drawing;
[0034] 3) The wire breakage rate has decreased significantly;
[0035] 4) The finished wire has good straightness after drawing.
