[0052] like Figures 1 to 11 The diagram shows the processing production line 100 and processing method of the present invention applied to the processing and production of two-section shoe lasts.

[0053] This includes a shoe last blank 200, a shoe last semi-finished product 400, and a shoe last finished product 500; the shoe last blank 200 has an integrally formed positioning post 210 at its top; the shoe last semi-finished product 400 has a top end face 410 at its top, a positioning hole 310 on its side, and an assembly hole 420 on its top end face 410; the shoe last finished product 500 includes a forefoot portion 520 and a heel portion 530.

[0054] The system includes a processing production line 100, which comprises a feeding robot 10, a side hole processing device 20, a milling and drilling device 30, a slanted hole processing device 40, a sawing machine 50, and a finishing machine 60. The side hole processing device 20 includes a clamping fixture 21 and a drilling assembly 22 disposed above the clamping fixture 21. The milling and drilling device 30 includes a feeding mechanism 31, a milling mechanism 32, and a drilling mechanism 33. The feeding mechanism 31 is located at the lower end of the milling mechanism 32 and the drilling mechanism 33. The slanted hole processing device 40 includes a first clamping mechanism 41 and a drilling mechanism 42 disposed above the first clamping mechanism 41. The first clamping mechanism 41 includes a clamping support 411 and a flipping mechanism mounted on the lower end of the clamping support 411. The sawing machine 50 includes a second clamping mechanism 51 and a cutting mechanism 52 connected together, the cutting mechanism 52 dividing the shoe last into a forefoot portion 520 and a heel portion 530; the finishing equipment 60 includes a processing mechanism 61 and a third clamping mechanism 62; the processing mechanism 61 includes a drive motor 611 and a cutting tool 612 connected together, the drive motor 611 driving the cutting tool 612 to cut the shoe last; the third clamping mechanism 62 includes a fixing fixture 621, a first drive module 622 and a second drive module 623 connected together, the shoe last is fixed on the fixing fixture 621, the first drive module 622 drives the shoe last to rotate along the horizontal plane, and the second drive module 623 drives the shoe last to rotate along the vertical plane.

[0055] The aforementioned production line helps improve the production efficiency and precision of shoe lasts. The side hole processing equipment 20 utilizes the connecting part on the shoe last blank 200 to horizontally place the blank 200 within the clamping fixture 21. The drilling component 22 drills vertically downwards, creating vertical positioning holes 310 on the side of the shoe last blank 200. These positioning holes 310 are used for clamping and positioning in subsequent processes. The milling and drilling equipment 30 uses a milling mechanism 32 to flatten the top, forming a top end face 410. The drilling mechanism 33 then processes assembly holes 420 on the top end face 410. The milling and drilling equipment 30 employs a dual-station structure to improve processing efficiency. The oblique hole processing equipment 40 uses a clamping support 411 to fix the shoe last semi-finished product 400 and a tilting component 412 to drive the shoe last semi-finished product 400 to tilt, enabling the processing of connecting holes 510 at various tilt angles. The saw 50 is used to cut the semi-finished shoe last 400 into a forefoot section 520 and a heel section 530, which meets the requirements of a two-piece shoe last. The finishing equipment 60 is equipped with a first drive module 622 and a second drive module 623, which has higher degrees of freedom of movement and can better perform cutting and grinding finishing.

[0056] The processing method includes the following steps:

[0057] Step S1, Injection molding: Injection molding is used to process a shoe last blank 200 with a positioning post 210 at the top;

[0058] Step S2, side hole processing: The shoe last blank 200 is transferred to the side hole processing equipment 20. The shoe last blank 200 is fixed in the clamping fixture 21 with the side facing upward by the positioning post 210. The drilling component 22 processes the positioning hole 310 on the side of the shoe last blank 200 to obtain the shoe last 300 to be processed.

[0059] Step S3, milling: The shoe last 300 to be processed is transferred to the milling and drilling equipment 30. The shoe last 300 to be processed is fixed on the feeding mechanism 31 through the positioning hole 310. The feeding mechanism 31 drives the shoe last 300 to be processed to move below the milling mechanism 32. The milling mechanism 32 cuts off the positioning post 210 and mills out the top end face 410 on the top of the shoe last 300 to be processed.

[0060] Step S4, Assembly hole 420 processing: The feed mechanism 31 drives the shoe last 300 to be processed to move below the punching mechanism 33. The punching mechanism 33 processes the assembly hole 420 on the top end face 410 to obtain the shoe last semi-finished product 400.

[0061] Step S5, oblique hole processing: The shoe last semi-finished product 400 is transferred to the oblique hole processing equipment 40. The shoe last semi-finished product 400 is fixed on the clamping support 411 through the positioning hole 310. The flipping component 412 drives the shoe last semi-finished product 400 to tilt. The drilling mechanism 42 vertically downward processes the oblique connecting hole 510.

[0062] Step S6, Cutting process: The semi-finished shoe last 400 after completing step S5 is transferred to the sawing machine 50. The semi-finished shoe last 400 is fixed on the second clamping mechanism 51 through the positioning hole 310. The cutting mechanism 52 cuts the finished shoe last 500 into a forefoot part 520 and a heel part 530 to obtain a two-section shoe last.

[0063] Step S7, finishing: Install a fixture on the assembly hole 420 of the two-section shoe last. The fixture is assembled and connected with the fixing fixture 621. The processing mechanism 61 cuts and grinds the surface of the two-section shoe last to perform finishing, and obtains the finished shoe last 500.

[0064] By adopting the above processing method, the accuracy of the positioning hole 310, assembly hole 420 and other hole positions is ensured, thereby ensuring the processing precision of the shoe last.

[0065] Furthermore, in step S2, the punching component 22 also processes a lanyard hole on the side of the shoe last blank 200; the lanyard hole is used to thread a lanyard so as to pull out the heel.

[0066] Further, in step S4, there are two assembly holes 420, each with a diameter of 5mm. Additionally, the drilling mechanism 33 also machines a limiting hole on the top end face 410. In step S7, the fixture is connected to the assembly holes 420 via self-tapping screws. The two assembly holes 420 are used to connect the fixture via self-tapping screws, and the limiting hole is used to connect the fixture and provide a limiting function.

[0067] Furthermore, in step S5, the inclined angle of the connecting hole 510 is 30-40°. Drilling a self-tapping screw into the inclined connecting hole 510 allows the forefoot 520 and the heel 530 to be connected as a whole. In step S6, during the machining process, a step needs to be machined between the forefoot 520 and the heel 530. This step can prevent the forefoot 520 and the heel 530 from twisting, ensuring the precision of the finishing process.

[0068] Furthermore, the clamping fixture 21 includes a base 211, a fixing plate 212 fixed to the base 211, and a movable plate 213 movably connected to the base 211; the movable plate 213 is provided with a slidingly connected mounting member 214, and the mounting member 214 is provided with a connecting hole 215, which is used to connect with the positioning post 210. This restricts the direction of the shoe last blank 200, ensuring the verticality of the positioning hole 310 and the lacing hole.

[0069] Furthermore, the feeding mechanism 31 includes a linear module 311 and a clamping seat 312 connected by a drive. The clamping seat 312 is provided with a horizontally arranged positioning pin 313, which is inserted into the positioning hole 310 for fixation. The positioning pin 313 cooperates with the positioning hole 310 to ensure the machining accuracy of the top end face 410 and the assembly hole 420.

[0070] Furthermore, the clamping support 411 is provided with a horizontally arranged limiting pin 413, which is inserted into the positioning hole 310 to achieve fixation and ensure the machining accuracy of the oblique hole.

[0071] Compared to existing technologies, the processing production line 100 and its processing method for shoe lasts involved in this invention employs a side hole processing equipment 20, a milling and drilling equipment 30, an oblique hole processing equipment 40, a sawing machine 50, and a finishing equipment 60 to form the processing production line 100. This automates the processing of shoe lasts, improves production efficiency, and reduces labor costs. The processing method helps improve the processing accuracy of shoe lasts. Specifically, positioning posts 210 are injection molded to facilitate fixing the shoe last to the side hole processing equipment 20, ensuring the accuracy of drilling holes on the side of the shoe last. Positioning holes 310 are machined on the side of the shoe last to facilitate fixed assembly with the milling and drilling equipment 30, the oblique hole processing equipment 40, and the sawing machine 50, thereby ensuring the accuracy of drilling holes 420 and connecting holes 510.

[0072] The above description merely illustrates preferred technical solutions of the present invention, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and the present invention also intends to include these modifications and variations.
