DETAILED DESCRIPTION

[0044] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0045] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0046] In addition, the terms "first", "second" and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, features defined as "first", "second" and "third" may explicitly or implicitly include one or more of the features.

[0047] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0048] The following is combined with Figures 1 to 9 The technical solution of the utility model is further illustrated by specific implementation methods.

[0049] The utility model provides a punching and cutting integrated machine head, comprising a mounting body 1, a cutting knife vertical driving device 21, a first rotating driving device 22, a cutting knife 23, a punching assembly 3 and a second rotating driving device 4;

[0050] The cutting knife 23 is movably mounted on the mounting body 1, the cutting knife vertical driving device 21 is used to drive the cutting knife 23 to move up and down, and the first rotating driving device 22 is used to drive the cutting knife 23 to rotate;

[0051] The punching assembly 3 is installed on the installation body 1, and the second rotation driving device 4 is used to drive the punching device 3 to rotate.

[0052] Since the cutting knife 23 and the punching assembly 3 are independently controlled by the first rotary drive device 22 and the second rotary drive device 4, the corresponding drive devices can be started separately as needed when leather processing is performed. This avoids unnecessary synchronous rotation of one tool module while another tool module is working, which reduces the wear of the tool, prolongs the service life of the tool, and reduces the production cost; on the other hand, it improves the working efficiency of the entire system.

[0053] Different tool modules use independent drive devices to make cutting and punching operations more flexible. During the production process, the operation mode can be switched at any time according to production needs, or cutting and punching operations can be performed at the same time to meet different processing needs. Furthermore, independent rotation drive devices mean that energy use is more optimized. When a module does not need to work, its corresponding drive device can be turned off to reduce energy consumption.

[0054] In summary, the integrated punching and shearing machine head of the present application is designed with independent first rotary drive device 22 and second rotary drive device 4 to respectively control the rotation of the cutting knife 23 and the punching assembly 3, thereby effectively improving work efficiency, reducing tool wear and damage, enhancing operational flexibility, simplifying maintenance and servicing, and optimizing energy use, bringing significant technological progress to the leather processing industry.

[0055] Further, the punching assembly 3 includes a piston rod 31, a punch rod 32, a punch 33, a connecting block 34, a piston 35, an upper sealing cover 36 and a lower sealing cover 37;

[0056] The piston rod 31 and one end of the punch rod 32 are connected via the connecting block 34, and the punch 33 is installed at the end of the punch rod 32 away from the connecting block 34;

[0057] The installation body 1 is provided with a first installation hole 11 and a second installation hole 12 which are vertically penetrated, and a manifold 51 is installed on one side of the installation body 1. The manifold 51 is provided with a first gas nozzle 521 and a second gas nozzle 522. The first gas nozzle 521 is communicated with the upper part of the first installation hole 11 through the first gas channel 111, and the second gas nozzle 522 is communicated with the lower part of the first installation hole 11 through the second gas channel 112.

[0058] The upper sealing cover 36 and the lower sealing cover 37 are used to block the upper part and the lower part of the first mounting hole 11 respectively. The piston 35 is installed on the piston rod 31. The top of the piston rod 31 protrudes from the top surface of the upper sealing cover 36, and the bottom of the piston rod 31 protrudes from the bottom surface of the lower sealing cover 37. The piston 35 is movably located between the upper sealing cover 36 and the lower sealing cover 37.

[0059] The punch rod 32 is movably mounted on the second mounting hole 12 .

[0060] In this embodiment, the upper sealing cover 36 and the lower sealing cover 37 are used to block the upper opening and the lower opening of the first mounting hole 11, respectively. The piston 35 is installed on the piston rod 31 and the piston 35 is located between the upper sealing cover 36 and the lower sealing cover 37, so that an upper piston cavity is formed between the upper sealing cover 36 and the piston 35, and a lower piston cavity is formed between the piston 35 and the lower sealing cover 37. Further, the interior of the mounting body 1 and the manifold 51 is provided with a first air passage 111 connecting the first mounting hole 11 and the first air nozzle 521 and a second air passage 112 connecting the first mounting hole 11 and the second air nozzle 522; the piston 35 drives the piston rod 31 and the punch rod 32 to move downward by ventilating the upper piston cavity through the first air nozzle 521 and the first air passage 111; the piston 35 drives the piston rod 31 and the punch rod 32 to move upward and reset by ventilating the lower piston cavity through the second air nozzle 522 and the second air passage 112, so as to realize repeated punching operation on the leather material. It is worth noting that, in the process of the piston rod 31 driving the punch rod 32 to move downward to punch holes, the second rotary drive device 4 drives the punch rod 32 to rotate, so as to punch the leather holes, so that the cut leather material is completely separated from the original material. The first mounting hole 11 can be effectively blocked by providing the upper sealing cover 36 and the lower sealing cover 37, so that the pneumatic system can maintain a high sealing performance during operation, avoiding the reduction of efficiency and safety hazards caused by gas leakage.

[0061] Furthermore, it also includes an upper nut 341 and a lower nut 342;

[0062] The upper nut 341 and the lower nut 342 are respectively screwed to the top of the piston rod 31, and the connecting block 34 can be moved on the top of the piston rod 31. The bottom surface of the upper nut 341 fits with the top surface of the connecting block 34, and the top surface of the lower nut 342 fits with the bottom surface of the connecting block 34.

[0063] Since the end of the connecting block 34 can move up and down on the rod body of the piston rod 31, the height position of the punch rod 32 can be adjusted by adjusting the height position of the connecting block 34 at the piston rod 31, thereby adjusting the stroke of the punch rod 32. When adjusting specifically, if it is necessary to raise the connecting block 34, first rotate the upper nut 341 upward, then move the connecting block 34 upward to the top surface against the upper nut 341, and finally rotate the lower nut 342 upward to the bottom surface of the connecting block 34; if it is necessary to lower the connecting block 34, first rotate the lower nut 342 downward, then move the connecting block 34 downward to the bottom surface against the lower nut 342, and finally rotate the upper nut 341 downward to the top surface of the connecting block 34. The structure is stable, and the adjustment method is also convenient and quick, thereby achieving the effect of improving the adjustment efficiency.

[0064] Furthermore, the second rotation driving device 4 includes a motor 41, a driving wheel 42, a synchronous wheel sleeve 43 and a synchronous belt 44;

[0065] The motor 41 is mounted on the mounting body 1 , the driving wheel 42 is mounted on the driving end of the motor 41 , the synchronous wheel sleeve 43 is sleeved on the outer side of the punch rod 32 , and the synchronous belt 44 is wound around the driving wheel 42 and the synchronous wheel sleeve 43 .

[0066] The motor 41 provides stable and controllable rotational power, the synchronous wheel sleeve 43 is sleeved on the outside of the punch rod 32, and the synchronous belt 44 is wound around the driving wheel 42 and the synchronous wheel sleeve 43, so that the rotation speed and angle of the punch rod 32 can be accurately controlled, ensuring efficient transmission of the punch rod 32.

[0067] Furthermore, it also includes a nut 38 and a first spring 39;

[0068] The nut 38 is mounted on the top of the punch 32;

[0069] The first spring 39 is sleeved on the rod body of the punch rod 32 , one end of the first spring 39 abuts against the nut 38 , and the other end of the first spring 39 abuts against the top of the synchronous wheel sleeve 43 .

[0070] During the punching process, the punch rod 32 and the punch head 33 are driven by the piston rod 31 to perform downward punching. When the punch rod 32 moves downward, the nut 38 compresses the first spring 39. When the punch rod 32 is reset upward after completing one punching, the compressed first spring 39 releases its elastic force and cooperates with the reset drive of the piston rod 31 to push the nut 38 upward to reset. In addition, the spring 38 disposed outside the punch rod 32 can also absorb part of the impact energy, reduce the wear between the punch rod 32 and the installation body 1 or the synchronous wheel sleeve 43, reduce the vibration and noise caused by the impact, and improve the overall stability and service life.

[0071] Further, by adjusting the position of the nut 38 on the punch rod 32, the compression degree of the first spring 39 can be indirectly changed, thereby adjusting its elastic force. This design allows the user to adjust the buffering effect and reset speed of the punch rod according to actual needs, thereby increasing the adaptability and flexibility of the device.

[0072] Furthermore, a flat key 321 is provided on the rod body of the punch rod 32 , and a vertical key slot 431 is provided inside the synchronous wheel sleeve 43 . The flat key 321 cooperates with the key slot 431 , and the flat key 321 moves up and down along the key slot 431 .

[0073] like Figure 8 and Fig. 9As shown, the connection between the punch rod 32 and the synchronous wheel sleeve 43 becomes more stable through the cooperation of the flat key 321 on the punch rod 32 and the keyway 431 in the synchronous wheel sleeve 43. This design can ensure that the punch rod 32 will not fall off or shake from the synchronous wheel sleeve 43 when punching materials up and down and rotating at high speed, thereby improving the stability and accuracy of punching.

[0074] Furthermore, the number of the punching assemblies 3 is two, and the mounting body 1 is provided with two first mounting holes 11 and two second mounting holes 12 .

[0075] In a preferred embodiment, the mounting body 1 has two first mounting holes 11 for mounting two piston rods 31 and two second mounting holes 12 for mounting two punch rods 32, so as to facilitate the two punching assemblies 3 to work simultaneously, thereby achieving the effect of improving the working efficiency of the puncher.

[0076] It is worth noting that the two punching assemblies 3 can be respectively installed with punches 33 of different sizes and models, thereby enhancing the flexibility and applicability of the equipment; further, the upper and lower punching drives of the two punching assemblies 3 are independently controllable, thereby further improving the flexibility of the equipment and improving production efficiency.

[0077] Furthermore, it also includes a press rod 61, a press foot 62 and a second spring 63;

[0078] The pressing rod 61 is disposed inside the piston rod 31, and the bottom of the pressing rod 61 protrudes from the bottom surface of the piston rod 31;

[0079] One end of the presser foot 62 is connected to the bottom of the press rod 61, and the other end of the presser foot 62 is provided with a through hole 621, and the through hole 621 is directly opposite to the punch 33;

[0080] The second spring 63 is sleeved outside the press rod 61 , one end of the second spring 63 abuts against the bottom surface of the piston rod 31 , and the other end of the second spring 63 abuts against the presser foot 62 .

[0081] like Figure 4As shown, a pressing rod 61 is provided inside the piston rod 31, and the bottom of the pressing rod 61 protrudes from the bottom surface of the piston rod 31; it also includes a presser foot 62 and a second spring 63, one end of the presser foot 62 is connected to the bottom of the pressing rod 61, and the other end of the presser foot 62 is penetrated by a through hole 621, and the through hole 621 is opposite to the punch 33, and the second spring 63 is installed between the presser foot 62 and the piston rod 31. In this embodiment, before working, the punch 33 is located above the other end of the presser foot 62. During working, the piston rod 31 drives the presser foot 62 to move downward through the pressing rod 61 until the presser foot 62 presses the product, and then the piston rod 31 continues to move downward to compress the second spring 63. The punch rod 32 and the punch 33 move downward with the piston rod 31 until the bottom of the punch 33 passes through the through hole 621 and touches the product, thereby achieving the purpose of punching the product. After the processing is completed, the piston rod 31 resets upward, and under the elastic force of the second spring 63, the presser foot 62 also returns to its original position. In this embodiment, by setting the presser foot 62, the product is pressed during processing to prevent it from moving, thereby ensuring the processing quality of the punching assembly 3, and the automatic reset of the presser foot 62 is achieved through the second spring 63, which is simple and fast without the need for additional drive.

[0082] Furthermore, it also includes a longitudinal driving device 7, the driving end of the longitudinal driving device 7 is installed and connected to the installation body 1, and the longitudinal driving device 7 is used to drive the installation body 1 to move up and down.

[0083] The introduction of the longitudinal drive device 7 enables the punching head to move up and down automatically, thereby improving the automation of the equipment. This not only reduces the need for manual operation, but also improves production efficiency. By controlling the up and down movement of the installation body 1 through the longitudinal drive device 7, the workflow of the punching process can be optimized. For example, before punching, the installation body 1 can automatically descend above the workpiece, and after punching is completed, it can automatically rise again, which is convenient for removing the workpiece and performing the next round of operations.

[0084] Furthermore, the longitudinal drive device 7 includes a support seat 71, a slide rail 72, a slider 73, a longitudinal drive motor 74, a screw rod 75 and a transmission block 76;

[0085] The slide rail 72 is vertically mounted on one side of the support seat 71, the slider 73 can slide with the slide rail 72, the longitudinal drive motor 74 is mounted on the top of the support seat 71, one end of the screw rod 75 is connected to the driving end of the longitudinal drive motor 74, and the transmission block 76 is mounted on the screw rod 75;

[0086] The transmission block 76 and the sliding block 73 are detachably connected to the installation body 1 .

[0087] like Figure 7As shown, the longitudinal drive motor 74 drives the screw rod 75 to rotate, and the transmission block 76 can move up and down following the screw rod 75. Specifically, the installation body 1 is provided with a connecting installation portion 113 installed and connected with the transmission block 76 and a matching installation portion 114 installed and connected with the slider 73, so that when the longitudinal drive motor 74 drives the screw rod 75 and the transmission block 76 to move, the installation body 1 can move following the transmission block 76, and the slider 73 cooperates with the slide rail 72 to ensure the stability and guidance of the installation body 1 during the longitudinal movement, which helps to reduce the blanking error caused by the shaking of cheap goods.

[0088] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way.
