Technical Field

[0001] This utility model relates to the field of shoemaking technology, specifically to a punching device for shoe castings. Background Technology

[0002] The production process of shoes is complex and diverse, involving multiple steps such as design, cutting, sewing, assembly, molding, and quality control. A wide variety of materials are used in shoemaking, commonly including leather, synthetic leather, fabric, rubber, and plastic. In shoemaking, the sole, upper, and laces are produced separately before being assembled. The sole, upper, and other footwear components require metal molds or auxiliary parts manufactured using casting processes for production; these are therefore called shoe castings.

[0003] Currently, shoe uppers require perforation during production, typically using hydraulic punching machines. However, different shoe upper materials have different thicknesses and require different perforation depths. Existing hydraulic punching machines are not convenient for adjusting the perforation depth according to different shoe upper materials, thus requiring improvement. Utility Model Content

[0004] The purpose of this invention is to provide a punching device for shoe castings, so as to solve the problem mentioned in the background art that the hydraulic punching machine cannot adjust the punching depth according to different shoe upper materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for shoe castings, comprising a worktable, a top frame and a drilling platform at the top of the worktable, a horizontal frame connected to the bottom of the top frame, a mounting base fixedly connected to the bottom of the horizontal frame, a drilling head assembly mounted at the bottom of the mounting base, the drilling platform located at the bottom of the drilling head assembly, a support frame fixedly connected to the top side of the worktable, an adjusting screw threaded onto the support frame, a limit frame connected to one end of the adjusting screw, a sensor mounted inside the limit frame, and a connecting block fixedly connected to the outer wall of the mounting base, the connecting block being located at the top of the limit frame and contacting the top of the sensor.

[0006] Preferably, the support frame has an "L" shaped structure when viewed from the side, and the support frame has multiple supports on the top side of the limiting frame.

[0007] Preferably, the limiting frame has a "C" shaped structure when viewed from above, with a notch on the top side of the limiting frame and a groove at the bottom of the notch, where a sensor is installed.

[0008] Preferably, the connecting block matches the notch structure on the top side of the limiting frame, and the limiting frame is connected to the lower end of the adjusting screw via a bearing.

[0009] Preferably, a hydraulic cylinder is fixedly connected to the top side of the top frame, and one end of the hydraulic cylinder is fixedly connected to the top side of the cross frame.

[0010] Preferably, a hydraulic sleeve rod and a buffer spring are fixedly connected to the bottom of the crossbar. The buffer spring is sleeved on the outer wall of the hydraulic sleeve rod. A hydraulic telescopic rod is telescopically connected to the lower end of the hydraulic sleeve rod. The lower ends of the hydraulic telescopic rod and the buffer spring are fixedly connected to the top side of the workbench.

[0011] Preferably, the hydraulic telescopic rod, hydraulic sleeve rod, and buffer spring are all symmetrically distributed about the bisector of the crossbeam, and the support frame is located inside the buffer spring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This device allows for easy adjustment of the punching depth of the punching head assembly, which can be adjusted according to different shoe upper materials, thereby improving the punching accuracy and the practicality of the device.

[0014] (2) This device has a manually adjustable adjusting screw on the support frame on the outside of the punching head assembly. The pitch of the adjusting screw corresponds to a certain adjustment depth. By rotating the adjusting screw, the height of the limiting frame can be adjusted. This allows the connecting block on the outer wall of the mounting base to contact the limiting frame during the lifting and lowering of the mounting base and the punching head assembly. This allows the limiting frame to limit the connecting block and the mounting base, thus ensuring the stability of the mounting base and the punching head assembly during the punching process while adjusting the punching depth.

[0015] (3) This device installs a sensor in the groove of the limiting frame. The sensor is a pressure sensor. By applying pressure to the sensor during the descent of the connecting block, the drilling pressure can be monitored in time, thereby ensuring the matching of drilling depth and pressure and avoiding the problem of insufficient drilling.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This utility model provides a technical solution: a drilling device for shoe castings, including a workbench 8, a top frame 2 and a drilling table 13 at the top of the workbench 8, a hydraulic cylinder 1 fixedly connected to the top side of the top frame 2, and one end of the hydraulic cylinder 1 fixedly connected to the top side of the cross frame 3. This structure can automatically lift and lower the cross frame 3, the mounting base 4 at the bottom of the cross frame 3 and the drilling head assembly 12 through the hydraulic cylinder 1, facilitating automatic drilling. The bottom of the top frame 2 is connected to the cross frame 3, and the bottom of the cross frame 3 is fixedly connected to a hydraulic sleeve rod 5 and a buffer spring 6. The buffer spring 6 is sleeved on the outer wall of the hydraulic sleeve rod 5. The lower end of the hydraulic sleeve rod 5 is telescopically connected to a hydraulic telescopic rod 7. The lower ends of the hydraulic telescopic rod 7 and the buffer spring 6 are fixedly connected to the top side of the workbench 8. The sleeve rod 5 and the buffer spring 6 are symmetrically distributed about the bisector of the crossbeam 3. The support frame 11 is located inside the buffer spring 6. This structure of hydraulic telescopic rod 7, hydraulic sleeve rod 5, and buffer spring 6 is a common structure in existing hydraulic punching equipment. It is mainly used to improve the lifting stability of the mounting base 4 and to provide cushioning when the punching head assembly 12 at the bottom of the mounting base 4 comes into contact with the material, thereby improving the service life of the punching head assembly 12 and the mounting base 4. The mounting base 4 is fixedly connected to the bottom of the crossbeam 3. The punching head assembly 12 is installed at the bottom of the mounting base 4. The punching table 13 is located at the bottom of the punching head assembly 12. The support frame 11 is fixedly connected to the top side of the worktable 8. The support frame 11 has an "L" shaped structure when viewed from the side. Multiple support frames 11 are provided about the top side of the limit frame 10. The structure allows for the installation of multiple adjusting screws 9 via multiple support frames 11, ensuring uniform height adjustment across multiple positions of the limiting frame 10. The limiting frame 10, viewed from above, has a "C"-shaped structure. A notch is formed on the top side of the limiting frame 10, and a groove is formed at the bottom of the notch. A sensor 15 is installed inside the groove. This sensor 15 is a pressure sensor, primarily used to monitor the pressure when the connecting block 14 descends. By detecting whether the pressure exceeds a set value, it determines whether the punching depth of the punch head assembly 12 at the bottom of the connecting block 14 meets the requirements. The sensor 15 is controlled by a PLC. The connecting block 14 matches the notch structure on the top side of the limiting frame 10. The limiting frame 10 is connected to the lower end of the adjusting screw 9 via a bearing. This structure allows for height adjustment by rotating the adjusting screw 9. The height of the limiting frame 10 is adjusted to allow for different height limits on the mounting base 4 and connecting block 14. Conversely, different heights of the mounting base 4 and connecting block 14 allow the bottom punching head assembly 12 to achieve different punching depths on the shoe upper. An adjusting screw 9 is threaded onto the support frame 11, with one end connected to the limiting frame 10. A sensor 15 is installed inside the limiting frame 10. A connecting block 14 is fixedly connected to the outer wall of the mounting base 4, with the connecting block 14 located at the top of the limiting frame 10 and contacting the top of the sensor 15. During production, the pitch of the adjusting screw 9 is consistent with the adjustment depth; for example, if the pitch of the adjusting screw 9 is 1mm, then each turn adjusts it by 1mm.This is to improve the accuracy of the height adjustment of the limit bracket 10.

[0024] Working principle: When using this shoe casting drilling device, the drilling depth is first adjusted according to the thickness of the material to be drilled. During adjustment, the adjusting screw 9 on the support frame 11 is rotated. One rotation of the adjusting screw 9 corresponds to 1mm. During the adjustment process, the adjusting screw 9 drives the height of the limiting frame 10 to be adjusted. After adjustment, processing can be carried out. During processing, the shoe upper material is placed on the top of the drilling table 13. Then, the hydraulic cylinder 1 pushes the cross frame 3 down, so that the cross frame 3 drives the drilling head assembly 12 at the bottom of the mounting base 4 to contact the shoe upper material for drilling. At the same time, the connecting block 14 on the outer wall of the mounting base 4 is located in the notch at the top of the limiting frame 10, so that the connecting block 14 contacts the sensor 15 inside the limiting frame 10. The sensor 15 monitors the pressure of the connecting block 14, thereby improving the accuracy of the drilling depth.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
