[0002] The field of mechanical processing often involves the processing of various holes. For the processing of various functional holes on aluminum tubes, punching technology is usually selected.

[0003] In the related art, the punching equipment includes a frame, a punching fixture for arranging special-shaped aluminum tubes, a driving cylinder installed on the frame and cooperating with the punching fixture, and a punching mechanism for punching special-shaped aluminum tubes. The frame is provided with a mounting table for arranging the punching fixture, the driving cylinder is arranged above the mounting table and the piston rod is arranged vertically downward. The punching fixture includes a base plate that can be mounted on the mounting table, a lower die seat welded to the base plate and used to support the punching pipe section of the special-shaped aluminum tube, an upper die seat installed at the end of the piston rod of the driving cylinder and cooperating with the lower die seat, and a plurality of auxiliary die seats located on both sides of the lower die seat. Among them, the auxiliary die seat is usually welded and fixed on the base plate and used to support the pipe section of the special-shaped aluminum tube that has not been punched.

[0004] Regarding the above-mentioned related technologies, since the lower die base and the auxiliary die base are both welded and fixed on the bottom plate, the entire punching fixture can only adapt to the punching process of one special-shaped aluminum tube, making the versatility of the punching fixture poor. Utility Model Content

[0005] In order to improve the problem of poor versatility of the contour tooling fixture on the punching equipment, the present application provides an aluminum tube punching tooling.

[0006] The present application provides an aluminum tube punching tool that adopts the following technical solution:

[0007] An aluminum tube punching tool, comprising a frame, a punching fixture for arranging a special-shaped aluminum tube, a driving cylinder installed on the frame and cooperating with the punching fixture, and a punching mechanism for punching the special-shaped aluminum tube, wherein the frame has a mounting table, the driving cylinder is vertically arranged above the mounting table, the punching fixture comprises a lower die seat detachably connected to the mounting table and used to support a punched tube section of the special-shaped aluminum tube, an upper die seat installed at the end of a piston rod of the driving cylinder and cooperating with the lower die seat, and an auxiliary clamping tool for supporting an unpunched tube section of the special-shaped aluminum tube;

[0008] The auxiliary clamping tooling includes a base plate, a support seat and a clamping seat. The base plate is detachably connected to the mounting table. A clearance groove for the lower mold seat is provided on the base plate. The support seat and the clamping seat are detachably connected to the base plate and are disposed on both sides of the lower mold seat.

[0009] By adopting the above technical solution, the lower die seat is upgraded from being directly welded and fixed on the base plate to being detachably connected to the installation table. The lower die seat is used to fix the perforated pipe section of the aluminum tube. The length of this pipe section is relatively small, and the lower die seat does not need to be disassembled and replaced unless necessary. Both the support seat and the clamping seat can be detachably connected to the base plate, which is convenient for disassembly and replacement, so that the shape of the support seat and the clamping seat can match the shape of the special-shaped aluminum tube, so that the punching fixture can adapt to special-shaped aluminum tubes of different shapes and sizes. Compared with the method of welding multiple auxiliary die seats to the base plate, the detachable setting method enhances the versatility of the punching fixture, so that the same set of punching equipment can handle more types of aluminum tube punching needs. The bottom plate is provided with a clearance groove, which can reduce the distance between the lower die seat and the support seat and the clamping seat, which is beneficial to improve the structural compactness of the auxiliary clamping tooling and improve the support stability of the non-perforated pipe section of the special-shaped aluminum tube.

[0010] Furthermore, the support seat includes a first connecting plate for connecting to the base plate and a supporting end for supporting the aluminum tube. The first connecting plate is arranged perpendicular to the base plate and is detachably connected to the base plate. The supporting end is detachably connected to an end of the first connecting plate away from the base plate. The supporting end is provided with a first slot for the aluminum tube to be inserted into.

[0011] By adopting the above technical solution, the first connecting plate and the bottom plate are detachably connected, which facilitates the removal and installation of the support seat from the bottom plate, and the operator can quickly replace the support seat as needed. The first connecting plate is arranged perpendicular to the bottom plate, which facilitates the adjustment of the angle of the support seat, thereby adapting to the support requirements of different parts of the aluminum tube and increasing the versatility of the punching fixture. The support end is detachably connected to the first connecting plate, which facilitates the replacement of support ends of different shapes and sizes. The first slot provided on the support end can ensure that the aluminum tube is stably supported during the punching process.

[0012] Furthermore, the clamping seat includes a second connecting plate for connecting to the base plate, a clamping end for clamping the aluminum tube, and a clamping assembly that cooperates with the clamping end and is used to compress the aluminum tube. The second connecting plate is arranged perpendicular to the base plate and is detachably connected to the base plate. The clamping end is detachably connected to an end of the second connecting plate away from the base plate. A second slot for the aluminum tube to be clamped is provided on the clamping end. The clamping assembly is arranged on the clamping end and is located adjacent to the second slot.

[0013] By adopting the above technical solution, the clamping seat is detachably connected to the base plate through the second connecting plate, which is convenient for the removal and installation of the clamping seat from the base plate. The operator can replace the clamping seat according to the shape and size of the aluminum tube to meet different punching requirements. The second connecting plate is arranged perpendicular to the base plate, which is convenient for the clamping seat to adjust the angle to meet the clamping requirements of different parts of the aluminum tube, thereby increasing the versatility and flexibility of the punching fixture. The clamping end is detachably connected to the second connecting plate, which is convenient for replacing clamping ends of different shapes and sizes to meet the clamping requirements of different aluminum tubes. The second card slot can ensure that the aluminum tube is stably and firmly clamped during the punching process. The clamping assembly cooperates with the clamping end to press the aluminum tube tightly, ensuring that the aluminum tube does not shake or shift during the punching process, thereby improving the accuracy and stability of the punching.

[0014] Furthermore, the clamping assembly includes a mounting seat, a pressing head, a driving handle and a connecting rod assembly. The mounting seat is fixedly connected to a side of the clamping end away from the lower die seat and located adjacent to the second slot. The driving handle is mounted on the mounting seat for driving the pressing head. The connecting rod assembly is mounted on the driving handle and the mounting seat. The pressing head is arranged on a side of the connecting rod assembly close to the second slot, and the end of the pressing head is aligned with the second slot.

[0015] By adopting the above technical solution, the mounting seat is fixedly connected to the side of the clamping end away from the lower die seat and located at the adjacent position of the second slot, ensuring the stability and reliability of the mounting seat, so that it can firmly support the pressing head and the driving handle. The driving handle is installed on the mounting seat to drive the pressing head, which is convenient for controlling the movement of the pressing head through the driving handle, thereby achieving the clamping and release of the aluminum tube. The pressing head is arranged on the side of the mounting seat close to the second slot, and its end is aligned with the second slot, ensuring that the pressing head can accurately press the outer wall of the aluminum tube in the second slot to firmly clamp the aluminum tube.

[0016] Furthermore, the connecting rod assembly includes a first connecting shaft and a second connecting shaft, and the driving handle has a connecting portion rotatably connected to the mounting seat and a gripping portion integrally connected to the connecting portion and used for gripping;

[0017] One end of the first connecting shaft is rotatably connected to the mounting seat, one end of the first connecting shaft away from the mounting seat passes through the connecting part and is fixedly connected to the pressure head, the second connecting shaft is arranged in the connecting part and one end of the second connecting shaft is rotatably connected to the connecting part, and one end of the second connecting shaft away from the connecting part is rotatably connected to the first connecting shaft.

[0018] By adopting the above technical solution, the driving handle realizes a dual-axis linkage effect through the first connecting shaft and the second connecting shaft. When the operator holds the handle and rotates it, the first connecting shaft and the second connecting shaft rotate at the same time, thereby driving the pressure head to clamp or release, making the transmission of clamping force more stable and reliable, and improving the clamping accuracy and stability.

[0019] Furthermore, the frame has a punching cavity for punching operations above the mounting table, and a row cavity for the punching knife to pass through is opened on the lower die base along the depth direction of the punching cavity, and a lower clamping groove for arranging an aluminum tube is opened on the side of the lower die base close to the upper die base, and the lower clamping groove and the row cavity are perpendicular to each other and connected to each other.

[0020] By adopting the above technical solution, the punching cavity on the frame provides space for the punching operation, and a row cavity is opened on the lower die base along the depth direction of the punching cavity, and the row cavity is passed through by the punching knife, ensuring that the punching knife can smoothly punch through the aluminum tube to complete the punching process. A lower clamping groove is opened on the side of the lower die base close to the upper die base for arranging the aluminum tube. The lower clamping groove and the row cavity are perpendicular to each other and interconnected, ensuring that the aluminum tube can be stably placed on the lower die base during the punching process, and the punching knife can smoothly pass through the aluminum tube to punch. By optimizing the positional relationship between the row cavity and the lower clamping groove on the lower die base, the punching operation can achieve the effect of side opening on the aluminum tube, so that the waste is directly pushed away from the tube body by the punching knife, avoiding the waste remaining in the tube caused by punching on the front of the aluminum tube.

[0021] Furthermore, the aluminum tube punching equipment also includes a pin for pushing the aluminum tube to be cut and a pushing member for driving the pin. A sliding groove for the pin to pass through and slide is opened in the height direction of the lower die base. The sliding groove is connected to the row cavity and the clamping groove. The pushing member is arranged below the lower die base.

[0022] By adopting the above technical solution, the ejector pin is used to push the aluminum tube to be unloaded, ensuring that the aluminum tube can be smoothly separated from the lower die seat after punching is completed. The pusher is located below the lower die seat and is the power source for the ejector pin to slide in the sliding groove and push the ejector pin upward, thereby pushing the aluminum tube out of the mold. The coordinated setting of the ejector pin and the pusher pin makes the unloading process faster and more stable, reducing the need for manual intervention.

[0023] 1. Furthermore, a waste pipe for discharging waste is provided on one side of the lower die base, one end of the waste pipe is connected to the side wall of the lower die base and aligned with the port of the cavity, and a waste box for receiving waste is provided below the port of the waste pipe away from the end connected to the lower die base.

[0024] 2. By adopting the above technical solution, the waste pipe is used to collect the waste generated during the punching process. The waste pipe is set on one side of the lower die base, and one end of it is connected to the side wall of the lower die base and aligned with the port of the row cavity, ensuring that the waste generated during the punching process can directly enter the waste pipe through the row cavity. The waste box is located below the port of the waste pipe away from the end connected to the lower die base, and is used to receive the waste falling from the waste pipe, which is convenient for subsequent cleaning and processing. When the punch punches holes in the row cavity, the waste generated will enter the waste pipe through the row cavity. The waste falls along the waste pipe under the action of gravity and finally falls into the waste box. The waste pipe is used to collect the waste generated during the punching process. The waste pipe is set on one side of the lower die base, and one end of it is connected to the side wall of the lower die base and aligned with the port of the row cavity, ensuring that the waste generated during the punching process can directly enter the waste pipe through the row cavity. The waste box is located below the port of the waste pipe away from the end connected to the lower die base, and is used to receive the waste falling from the waste pipe, which is convenient for subsequent cleaning and processing. When the punch punches holes in the row cavity, the waste generated will enter the waste pipe through the row cavity, and the waste will fall along the waste pipe under the action of gravity and finally fall into the waste box.

[0025] Furthermore, the waste pipe has a first pipe section and a second pipe section that are integrally connected, one end of the first pipe section away from the second pipe section is connected to the lower die base, and one end of the second pipe section away from the first pipe section is connected to the bottom plate;

[0026] The first pipe section is inclined downward from one end connected to the lower mold base to one end close to the second pipe section to guide the waste to fall, and the second pipe section is vertically downward from one end close to the first pipe section to one end connected to the bottom plate, and the port of the second pipe section is aligned with the waste box.

[0027] By adopting the above technical solution, the first pipe section and the second pipe section connected in one piece of the waste pipe form a complete waste falling channel, the end of the first pipe section away from the second pipe section is connected to the lower die seat, ensuring that the waste can directly enter the waste pipe from the cavity, and the end of the second pipe section away from the first pipe section is connected to the bottom plate, so that the waste pipe can be firmly connected to the equipment to avoid shaking during the waste falling process. The first pipe section is tilted downward, which can effectively guide the waste to fall and smoothly enter the second pipe section. The tilt angle can be adjusted according to actual needs to optimize the falling speed and smoothness of the waste. The second pipe section is set vertically downward, so that the waste can maintain linear motion during the falling process, reducing the resistance caused by the change of direction. The port of the second pipe section is aligned with the waste box, ensuring that the waste can accurately fall into the waste box to avoid scattering or splashing of the waste.

[0028] Furthermore, an annular induction switch is provided below the second pipe section, the annular induction switch is located above the waste box and is connected to the waste pipe, and the annular induction switch is electrically connected to the driving cylinder.

[0029] By adopting the above technical solution, the waste passes through the first pipe section, the second pipe section and the annular induction switch in sequence and falls into the waste box. When the annular induction switch recognizes that waste passes through, the driving cylinder drives the upper die seat to lift, and the upper die seat continues to press against the lower die seat.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. By setting the lower die base, support base, clamping base, etc. in a detachable connection mode, the punching fixture can adapt to special-shaped aluminum tubes of different shapes and sizes, enhancing the versatility and flexibility of the auxiliary clamping tooling, so that the same set of auxiliary clamping tooling can adapt to more types of aluminum tube punching needs, reducing production costs and maintenance costs. The first connecting plate and the second connecting plate enable the support base and the clamping base to adjust the angle, increasing the versatility of the punching fixture, so that it can adapt to the support and clamping needs of different parts of the aluminum tube. The coordination of the clamping assembly and the clamping end ensures that the aluminum tube is stably and firmly clamped during the punching process, preventing the aluminum tube from shaking or displacing, and further improving the accuracy and stability of the punching;

[0032] 2. By optimizing the positional relationship between the upper cavity and the lower clamping groove of the lower die base, the punching operation can achieve the effect of side opening on the aluminum tube, avoiding the situation where waste is left in the tube and improving the punching accuracy. The matching setting of the ejector and the pusher ensures that the aluminum tube can be smoothly separated from the die after the punching is completed, reducing the need for manual intervention and improving production efficiency;

[0033] 3. The waste pipe is divided into the first pipe section and the second pipe section. The inclined design of the first pipe section can effectively guide the waste to fall, and the vertical design of the second pipe section ensures that the waste can smoothly enter the waste box. The annular induction switch can identify whether there is aluminum sheet waste being punched down by the punch, thereby playing an error-proofing effect. When the annular induction switch identifies that there is waste passing, the driving cylinder drives the upper die seat to lift, and the upper die seat continues to be pressed against the lower die seat.
