[0032] like Figure 1 As shown, an embodiment of the utility model provides a wire drilling and punching device, comprising a wire feeding reel 10, a straightening assembly 20, a punching assembly 30 and a center hole processing assembly 40. The wire feeding reel 10 is used to feed the wound wire raw material. Since the wire raw material is wound, the wire needs to be straightened by the straightening assembly 20 to facilitate the subsequent punching and drilling accuracy of the punching assembly 30 and the center hole processing assembly 40.

[0033] At the same time Figure 2 As shown, the wire feeding disc 10 includes a disc seat 11, a disc frame 12, and a wire feeding drive unit. The disc seat 11 is fixedly arranged, the disc frame 12 is rotatably connected to the disc seat 11, and the wire feeding drive unit is arranged on the disc seat 11, and is transmission-connected to the disc frame 12, and is used to drive the disc frame 12 to rotate. Specifically, the wire feeding drive unit includes a wire feeding motor 13, a mutually meshing driving gear 14, and a driven gear 15, the driving gear 14 is connected to the output shaft of the wire feeding motor 13, and the driven gear 15 is connected to the rotating shaft of the disc frame 12, so that the disc frame 12 is driven to rotate by the wire feeding motor 13, and the rotation speed of the disc frame 12 is reduced by the gear meshing ratio.

[0034] As a preferred embodiment, in this embodiment, a limiting rod 16 is further provided on the outer side of the disc rack 12, the bottom of the limiting rod 16 is connected to the disc base 11, and a limiting wheel 17 is provided on the inner surface of the limiting rod 16. The limiting wheel 17 is freely rotatably connected to the limiting rod 16, and the limiting wheel 17 is used to make rolling contact with the outermost layer of the wound iron wire raw material to limit the position of the iron wire roll and prevent it from being completely loosened and detached from the disc rack 12 in the wound state.

[0035] At the same time Figure 3 As shown, the straightening assembly 20 includes a vertical straightening part, a horizontal straightening part and a traction part. The vertical straightening part includes a vertical straightening seat 21 and a plurality of vertical straightening wheels 22 rotatably arranged on the vertical straightening seat 21, and the horizontal straightening part includes a horizontal straightening seat 23 and a horizontal straightening wheel 24 rotatably arranged on the horizontal straightening seat 23. The vertical straightening wheels 22 are vertically distributed in two layers, and the horizontal straightening wheels 23 are horizontally distributed in two rows, so that the wire can be vertically and horizontally straightened by the straightening wheels when passing through, which is convenient for subsequent processing. The traction part includes a traction seat 25, a traction wheel 26 rotatably arranged on the traction seat 25, and a traction motor 27 (with a reducer) that drives the traction wheel 26 to rotate through a gear set, and the traction wheel 26 contacts the wire and drives the wire to be transported by static friction.

[0036] Among them, the vertical straightening seat 21, the horizontal straightening seat 22, and the traction seat 25 are all arranged on the straightening mounting platform 28. The two ends of the straightening mounting platform 28 are respectively provided with a feed pipe 29 and a discharge pipe 210, which are used to guide the feeding and discharging of the iron wire so that the iron wire moves along a preset path.

[0037] At the same time Figure 4 As shown, the stamping assembly 30 includes a stamping die and a hydraulic punch 31. Among them, the hydraulic punch 31 used has a pressure-maintaining function compared with a traditional punch, that is, the stamping state can be maintained after stamping, which is convenient for the center hole processing assembly 40 to process the center positioning hole. The stamping die includes a die seat 32, a guide die 33 and a forming lower die 34, and the guide die 33 and the forming lower die 34 are both arranged on the die seat 32. The guide die 33 is provided with a guide hole 35, and the guide hole 35 is used to guide the straightened iron wire. At the same time, a gap is provided between the guide die 33 and the forming lower die 34, and the gap is used for cutting by the cutting knife 36, so that the iron wire located in the forming lower die 34 is an independent part after cutting.

[0038] In this embodiment, the lower forming die 34 is provided with an introduction hole 37 and a punching groove 38, and the height of the punching groove 38 is lower than the height of the introduction hole 37, so that the punched iron wire is bent into a Z shape to meet the processing requirements. At the same time, the width of the punching groove 38 matches the outer diameter of the iron wire, so that after the punching stroke of the upper forming die 39 is in place, the iron wire part in the punching groove 38 can be completely fixed and positioned, which is convenient for the processing of the center hole processing component 40.

[0039] The cutting blade 36 and the forming upper die 39 are both connected to the output end of the hydraulic punch 31 so as to perform cutting and stamping by hydraulic pressure.

[0040] At the same time Figure 5As shown, the center hole processing assembly includes a drill bit 41, a drilling motor 42 that is transmission-connected to the drill bit 41, and a drilling displacement unit that drives the drilling motor 42 to feed or retract. Among them, the drilling displacement unit includes a linear guide 43 arranged along the feeding direction, a slider 44 fixed to the drilling motor 42, and a driving cylinder 45. The slider 44 is slidably connected to the linear guide 43, and the piston rod end of the driving cylinder 45 is connected to the drilling motor 42. Therefore, in the process of the drilling motor 42 driving the drill bit 41 to rotate continuously, the driving cylinder 45 drives the drilling motor 42 and the drill bit 41 to feed to the extreme position, corresponding to the bottom of the stamping groove 38, that is, the center positioning hole processing of the iron wire is completed. After the drilling processing is completed, the subsequently transported iron wire is inserted into the introduction hole 37 to eject the iron wire that has completed all the processing.

[0041] In summary, the wire drilling and punching equipment provided in this embodiment can automatically, efficiently and with high quality complete the stamping and drilling of a large number of wires through the sequential arrangement of the wire feeding reel 10, the straightening assembly 20, the punching assembly 30 and the center hole processing assembly 40 and the coordination of the process, and is suitable for assembly line production.

[0042] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
