[0036] The following is for reference. Figures 1-4 Describes a wire drawing machine 100 according to an embodiment of the present invention.

[0037] Example 1

[0038] like Figures 1-3 As shown, this embodiment provides a wire drawing machine 100, which includes a worktable 4, a horizontal linear guide rail assembly 2, and a wire drawing mechanism 3.

[0039] Workbench 4 is used to fix the workpiece.

[0040] The horizontal linear guide assembly 2 is positioned above the worktable 4.

[0041] The wire drawing mechanism 3 includes a first mounting member 31, a second mounting member 32, and a wire drawing device 34. The second mounting member 32 is movably mounted on the first mounting member 31 in a vertical direction, and the wire drawing device 34 is fixed on the second mounting member 32. Thus, the second mounting member 32 is used to drive the wire drawing device 34 to approach or move away from the workpiece to be processed, and the wire drawing device 34 is used to draw wires on the surface of the workpiece. The first mounting member 31 is slidably mounted on the horizontal linear guide assembly 2, and the wire drawing mechanism 3 is used to move along the horizontal linear guide assembly 2 under the control of the operator.

[0042] The vertical linear drive device 5 is fixed to the first mounting member 31. The vertical linear drive device 5 drives the second mounting member 32 so that the second mounting member 32 drives the wire drawing device 34 to press against the workpiece surface in the vertical direction. That is to say, the vertical linear drive device 5 provides a vertical driving force to the wire drawing device 34 through the second mounting member 32.

[0043] It should be further explained that the wire drawing device 34 can be moved closer to or away from the worktable 4 by the operator dragging the second mounting part 32 or by the vertical linear drive device 5 driving the second mounting part 32. However, during the wire drawing process after the wire drawing device 34 contacts the workpiece surface, the vertical linear drive device 5 needs to continuously drive the second mounting part 32 to make the force of the wire drawing device 34 pressing on the workpiece surface more stable.

[0044] When using a wire drawing machine 100 to draw wires on the surface of a workpiece, the main steps are as follows:

[0045] S1: The operator fixes the workpiece on the worktable 4.

[0046] S2: Align the wire drawing device 34 with the workpiece in the vertical direction, that is, the projection of the wire drawing device 34 in the vertical direction is located on the workpiece.

[0047] S3: The second mounting component 32 drives the wire drawing device 34 to move in a direction perpendicular to the worktable until the wire drawing device 34 contacts the workpiece.

[0048] S4: In the drawing process, the vertical linear driving device 5 provides driving force in the vertical direction to the drawing device 34 through the second mounting member 32, so as to press the drawing device 34 on the surface of the workpiece, and the operator drives the drawing mechanism 3 to move on the surface of the workpiece. By arranging the horizontal linear guide rail assembly 2, the drawing mechanism 3 can be guided to move along a straight line, which assists the operator to draw a line, makes the drawing more uniform, saves time and labor, and improves the drawing quality. At the same time, compared with manually pressing the drawing device 34, the output force of the vertical linear driving device 5 is more stable, which can further improve the uniformity of the drawing and the drawing quality.

[0049] As shown in Figure 1 , further, the horizontal linear guide rail assembly 2 includes a first linear guide rail 21 and a second linear guide rail 22. The first linear guide rail 21 is arranged above the workbench 4, and the first linear guide rail 21 includes two, the two first linear guide rails 21 are arranged in parallel in the second direction, and each first linear guide rail 21 extends in the first direction. The second linear guide rail 22 extends in the second direction and is slidably arranged between the two first linear guide rails 21, and the first direction, the second direction and the vertical direction are perpendicular to each other.

[0050] It should be further explained that the parallel arrangement here means that the two first linear guide rails 21 are arranged in parallel and spaced apart in the second direction.

[0051] In the related art, although the automatic drawing machine has better drawing effect than the manual drawing machine, the investment cost of the automatic drawing machine is high, with tens of thousands of dollars or more, and the processable workpiece size is limited. Therefore, the applicant improves the manual drawing machine to reduce the cost. At the same time, the lengths of the first linear guide rail 21 and the second linear guide rail 22 can be customized according to actual needs to meet the processing needs of large workpieces.

[0052] As shown in Figure 1 and Figure 2 , in some optional examples, the two ends of the second linear guide rail 22 are provided with first guide blocks 221, the first guide blocks 221 are arranged one by one with the first linear guide rails 21, and the first guide blocks 221 are provided with first guide grooves, and the first linear guide rails 21 can be embedded in the first guide grooves, so as to realize the sliding fit between the first guide blocks 221 and the first linear guide rails 21.

[0053] As shown in Figure 3As shown, in some optional examples, the first mounting member is provided with a second guide block 312, which is in sliding fit with the second linear guide rail 22. The second guide block 312 is provided with a second guide groove, and the second linear guide rail 22 can be embedded in the second guide groove, so as to realize the sliding fit between the second guide block 312 and the second linear guide rail 22.

[0054] In some optional examples, the two ends of the second linear guide rail 22 are provided with first guide rollers, which are arranged in one-to-one correspondence with the first linear guide rail 21. The first linear guide rail 21 is formed with a first guide groove extending in the first direction, and the first guide roller can roll in the first guide groove.

[0055] In some optional examples, the first mounting plate is provided with a second guide roller, and the second linear guide rail 22 is formed with a second guide groove extending in the second direction, and the second guide roller can roll in the second guide groove.

[0056] As Figure 1 shown, in one specific application scenario, the operator drives the wire drawing mechanism 3 to move in the first direction and the second direction, so that the projection of the wire drawing mechanism 3 in the vertical direction is located on the surface of the workpiece, thereby realizing the alignment of the wire drawing mechanism 3 and the workpiece. Then, the operator drives the wire drawing device 34 to move in the vertical direction until the wire drawing device 34 contacts the workpiece. During the wire drawing process, the wire drawing device 34 is pressed on the surface of the workpiece, and the operator drives the wire drawing mechanism 3 to move on the surface of the workpiece. By arranging the first linear guide rail 21 and the second linear guide rail 22, the wire drawing mechanism 3 can be guided to move along a straight line, and the first guide rail and the second guide rail assist the operator to drive the wire drawing mechanism 3 to draw a line, so that the wire drawing is more uniform, and the wire drawing quality is improved.

[0057] As Figure 1 and Figure 2 shown, further, the wire drawing device 34 includes a wire drawing roller 342 and a wire drawing motor 341. The wire drawing motor 341 drives the wire drawing roller 342 to rotate, and the outer periphery of the wire drawing roller 342 is provided with a sand belt. The wire drawing motor 341 is fixed on the second mounting member 32, and the output shaft of the wire drawing motor 341 is fixedly connected to the axis of the wire drawing roller 342.

[0058] Embodiment Two

[0059] As Figure 3As shown, further, the vertical linear drive device 5 comprises a first cylinder 51 and a pressure valve 52 connected to the first cylinder 51, the pressure valve 52 being used to adjust the output pressure of the first cylinder 51. On the one hand, compared with the linear motor drive, the embodiment adopts the cylinder drive, which is lower in cost and has greater load and wider application range; on the other hand, in the actual industrial environment, because the working principle of the cylinder is based on the compression and expansion of gas, as long as the gas source is stable, the movement speed and force output are relatively stable. While the linear motor may be affected by electromagnetic interference, power fluctuations and other factors, resulting in a decline in movement accuracy and stability, thus the cylinder drive is more stable; on the other hand, the maintenance of the cylinder drive is simpler. In the embodiment, by setting the pressure valve 52, the force of the wire drawing device 34 pressing on the surface of the workpiece can be adjusted, further improving the uniformity and quality of wire drawing.

[0060] As shown in Figure 3 As shown, further, the vertical linear drive device 5 further comprises a reversing valve 53 connected to the first cylinder 51 to control the movement direction of the first cylinder 51.

[0061] As shown in Figure 3 As shown, further, the first mounting member 31 is fixedly connected with a third guide rail 313 extending in the vertical direction, and the second mounting member 32 is fixedly connected with a third guide block 323 movably arranged on the third guide rail 313.

[0062] Embodiment three

[0063] The embodiment is basically the same as the first embodiment, and further limits the specific structure of the wire drawing mechanism 3.

[0064] As shown in Figure 3 As shown, further, the first mounting member 31 comprises a horizontal extension 314, a first vertical section 315 and a second vertical section 316, the first vertical section 315 being located above the horizontal extension 314, and the second vertical section 316 being located below the horizontal extension 314. The lower surface of the horizontal extension 314 is in sliding fit with the horizontal linear guide rail assembly 2, the vertical linear drive device 5 is fixed on the first vertical section 315, the first vertical section 315 is connected with the upper surface of the horizontal extension 314 through the reinforcing rib 33, and the second mounting member 32 is slidingly arranged on the second vertical section 316. Thus, the second guide block 312 on the lower surface of the horizontal extension 314 is pressed on the second linear guide rail 22 by the gravity of the vertical linear drive device 5 and the first vertical section 315, improving the stability and reliability of the cooperation between the second guide block 312 and the second linear guide rail 22. By arranging the reinforcing rib 33 between the first vertical section 315 and the horizontal extension 314, the stability and reliability of the structure are improved.

[0065] In combination with the above-described embodiment two, the lower surface of the horizontal extension section 314 is provided with a second guide block 312, which is in sliding fit with the second linear guide rail 22. Alternatively, the lower surface of the horizontal extension section is provided with a second guide roller, which is in rolling fit with the second linear guide rail 22.

[0066] As shown in Figures 1-3 Further, the second vertical section 316 is provided with a guide roller 3161, which is pivotally mounted on the second vertical section 316 and is spaced between the second vertical section 316 and the horizontal linear guide rail assembly 2, and the pivot axis of the guide roller 3161 is parallel to the vertical direction. Different assemblies are distributed on the first vertical section 315 and the second vertical section 316, and the counterweight on the second vertical section 316 is smaller than that on the first vertical section 315, which can cause the second vertical section 316 to abut against the horizontal linear guide rail assembly 2. The guide roller 3161 can space the second vertical section 316 from the horizontal linear guide rail assembly 2, so that the movement of the second vertical section 316 is smoother, and the uniformity and quality of the wire drawing are further improved.

[0067] As shown in Figure 3 Further, the first vertical section 315 is further provided with a switch device 311, which is electrically connected to the wire drawing device 34 to control the operating state of the wire drawing device 34. The position of the first vertical section 315 in the vertical direction is fixed, and the first vertical section 315 is farther away from the wire drawing device 34 than the second vertical section 316. Arranging the switch device 311 on the first vertical section 315 is conducive to improving the safety of operation and avoiding the operator being scratched by the wire drawing device 34.

[0068] Further, the switch device 311 includes a switch button and an emergency stop button.

[0069] In some optional examples, the first mounting member 31 can be configured as a T-shaped plate arranged in one piece.

[0070] As shown in Figure 3 In other optional examples, the first mounting member 31 can be configured as a first L-shaped plate member and a second L-shaped plate member arranged in separate pieces. The first L-shaped plate member includes the first horizontal extension section and the first vertical section 315 connected thereto, and the upper surface of the first horizontal extension section is connected to the first vertical section 315 through the reinforcing rib 33; the second L-shaped plate member includes the second horizontal extension section and the second vertical section 316 connected thereto, and the lower surface of the second horizontal extension section 314 is provided with the second guide block 312. The first horizontal extension section and the second horizontal extension section are fixedly connected through fasteners to form the above-described horizontal extension section 314.

[0071] Embodiment four

[0072] As shown in Figures 1-3As shown, the wire drawing machine 100 further includes a gripping part 6, one end of which is fixedly connected to the second mounting member 32, and the other end of which is inclined upwards in a direction away from the wire drawing device 34. The operator can move the wire drawing device 34 by gripping the gripping part 6. By inclining the other end of the gripping part 6 upwards in a direction away from the wire drawing device 34, the safety and convenience of the wire drawing operation are improved.

[0073] Example 5

[0074] like Figure 3 As shown, the wire drawing mechanism 3 further includes a vibration-absorbing elastic element 35. One end of the vibration-absorbing elastic element 35 is fixedly connected to the first mounting member 31, and the other end of the vibration-absorbing elastic element 35 is fixedly connected to the second mounting member 32. The vibration-absorbing elastic element 35 can absorb vibrations during the wire drawing process, thereby improving the uniformity of the load applied by the wire drawing device 34 to the workpiece surface.

[0075] Example 6

[0076] like Figure 4 As shown, the wire drawing machine 100 further includes a base frame 1 and a lifting assembly 8. The base frame 1 is used to install the first linear guide rail 21. The lifting assembly 8 is installed on the base frame 1 and located below the first linear guide rail 21. The lifting assembly 8 is used to drive the worktable 4 to move in the vertical direction, so that the worktable 4 drives the workpiece to approach the wire drawing device 34 in the vertical direction.

[0077] As can be seen from the above embodiment 2, since the worktable 4 can drive the workpiece to approach the wire drawing device 34 in the vertical direction, the stroke of the vertical linear drive device 5 can be reduced, and the cost of the short-stroke vertical linear drive device 5 is lower.

[0078] like Figure 4 As shown, the lifting assembly 8 further includes two lead screws 81 arranged in parallel in the second direction. Each lead screw 81 is arranged vertically and its bottom end is fixedly connected to a transmission gear 82. The two transmission gears 82 are connected by a transmission chain 83. The worktable 4 is located between the two lead screws 81 and is movably mounted on the lead screws 81. By driving one transmission gear 82 to rotate, the transmission chain 83 drives the other transmission gear 82 to rotate, thereby causing the two lead screws 81 to rotate synchronously and drive the worktable 4 to move in the vertical direction. In this embodiment, the lifting assembly 8 uses this synchronous lifting method to effectively avoid workpiece tilting or positional displacement caused by asynchronous lifting on both sides, thereby improving machining accuracy.

[0079] In one specific example, the lifting assembly 8 also includes an input rocker arm, which is coaxially mounted with one of the drive gears. When the operator turns the rocker arm, it can drive the drive gear to rotate.

[0080] In one specific example, the height of the lead screw 81 is 0.8m~1.2m. The stroke of the vertical linear driving device 5 is 200mm.
