Description
Technical Field
[0001] The present application relates to the technical field of mechanical parts processing equipment, and in particular to a stamping tool. Background Art
[0002] At present, some parts often need to be punched using stamping tools, such as stainless steel hooks. Stainless steel hooks are arc-shaped strips and need to be punched in the middle of the product.
[0003] Conventional stamping tooling includes a machine table, a lower die set on the machine table, and an upper die located above the lower die and capable of being raised and lowered. The part to be processed is placed and fixed in the designated installation position of the lower die, and the upper die is driven to move by a driving source such as a hydraulic cylinder. The punching knife on the upper die can punch holes at the designated position.
[0004] The above-mentioned stamping tooling usually requires operators to manually load and unload materials. Since the stainless steel hook structure is relatively small, manual loading and unloading will result in low work efficiency, which needs to be improved. Utility Model Content
[0005] In order to facilitate automatic loading and unloading of products and thus improve work efficiency, the present application provides a stamping tool.
[0006] This application provides a stamping tool, which adopts the following technical solution:
[0007] A stamping tool, comprising:
[0008] A machine platform, wherein a lower die and an upper die located above the lower die are provided on the machine platform, a first driving source for driving the upper die to move vertically back and forth is provided on the machine platform, and a punching knife is provided at the bottom of the upper die;
[0009] A loading mechanism, comprising a storage track for storing workpieces to be processed, and the workpieces to be processed can be sequentially slid out from the end of the storage track;
[0010] A transfer piece, which is used to move the workpiece to be processed from the end of the storage track to the lower die;
[0011] A blanking track is provided on one side of the lower die for allowing the processed workpiece to slide out.
[0012] By adopting the above technical solution, when in use, multiple workpieces to be processed can be placed in the storage track for storage at the same time, so that the workpieces to be processed can fall from the bottom in turn, and the transfer piece can push the parts from the bottom of the storage track to the designated position of the lower mold in turn. When the upper mold is driven down by the first driving source, the workpiece to be processed can be stamped, and the processed workpiece can slide from the unloading track, and the transfer piece continues to transfer the next workpiece to be processed, realizing automatic loading and unloading of the stamping tooling, without the need for manual automatic loading and unloading, thereby improving work efficiency.
[0013] Optionally, the material storage track is vertically arranged and has a material discharge port at the bottom. The material transfer component includes a movable plate located at the bottom of the material storage track, and a second driving source for driving the movable plate to move horizontally is provided on the machine platform.
[0014] By adopting the above technical solution, the movable plate can be driven to and fro by the second driving source, and the workpieces to be processed discharged from the discharge port are driven to move to the lower mold in sequence.
[0015] Optionally, a first sliding groove for the movable plate to move is provided on the lower die, the first sliding groove runs through both ends of the lower die, and a limiting member is slidably connected to the lower die and can abut against the workpiece to be processed to limit the workpiece to be processed.
[0016] By adopting the above technical solution, the movable plate can push the workpiece to be processed into the first slide groove and limit the final position by the limit member. After the workpiece to be processed is clamped by the limit member and the movable plate, the workpiece to be processed can be clamped and fixed, making it convenient to lower the upper mold so that the punching tool can punch the workpiece to be processed.
[0017] Optionally, the limiting member is a limiting pin, and a sliding hole is provided on the lower mold for the limiting pin to move vertically. The lower mold is hollow and one end of the limiting pin is located in the inner cavity of the lower mold. The lower mold is connected to an air pipe, and the air pipe is communicated with the inner cavity of the lower mold.
[0018] By adopting the above technical solution, the limit hole can slide in the sliding hole. When the limit pin extends out of the sliding hole, it can be abutted by the workpiece to be processed to limit the workpiece. When the limit pin slides back into the sliding hole, the workpiece to be processed can continue to slide along the first sliding groove, thereby sliding off the unloading track for unloading; and the limit pin can be driven by airflow, which is easy to operate.
[0019] Optionally, the inner cavity of the lower mold is slidably connected to a pneumatic plate, one end of the limit pin is fixed to the pneumatic plate, two air pipes are connected on the lower mold, and the two air pipes are respectively connected to the cavities on both sides of the pneumatic plate.
[0020] By adopting the above technical solution, when air is supplied to the cavities on different sides of the pneumatic plate, the pneumatic plate can be driven to move back and forth, thereby driving the limit pin located on the pneumatic plate to move.
[0021] Optionally, a support seat is provided on the machine, one end of the support seat is connected to the lower mold, and a second slide groove is opened on the top, the first slide groove and the second slide groove are connected and the bottom walls are flush, the storage assembly is arranged on the support seat and the discharge port is opposite to the second slide groove, and the movable plate is slidably connected to the second slide groove.
[0022] By adopting the above technical solution, a support seat is set to provide support for the transferred material, and a second slide groove is set to provide moving space for the movable plate. Since the discharge port and the second slide groove are opposite to each other, the workpiece to be processed falling from the discharge port can fall into the second slide groove and be pushed by the movable plate.
[0023] Optionally, the distance between the bottom wall of the second chute and the discharge port is less than the height of two workpieces to be processed, and the thickness of the movable plate is less than or equal to the height of the workpieces to be processed.
[0024] By adopting the above technical solution, only one of the workpieces to be processed can completely slide out from the discharge port each time and be located between the bottom wall of the second chute and the discharge port, so that when the movable plate moves, only one workpiece to be processed can be pushed to move, and the thickness of the movable plate is less than the height of the workpiece to be processed, so that when the movable plate moves, only one workpiece to be processed can be moved.
[0025] Optionally, the transfer piece is in the shape of an elongated strip, and when the movable plate pushes the workpiece to be processed toward the lower mold, the movable plate is always located at the bottom of the discharge port, and the distance between the movable plate and the discharge port is smaller than the height of the workpiece to be processed.
[0026] By adopting the above technical solution, when the movable plate pushes a workpiece to be processed to move for processing, the movable plate is still partially located under the discharge port, thereby preventing other workpieces to be processed from falling from the discharge port.
[0027] Optionally, a mounting groove is provided at one end portion of the movable plate, a clamping head is slidably connected in the mounting groove, and an elastic member is provided between the clamping head and the inner wall of the mounting groove away from the opening.
[0028] By adopting the above technical solution, when the movable plate moves and the limit pin clamps the workpiece to be processed, the elastic part is compressed to store elastic potential energy. When the limit pin drops, the elastic part releases the elastic potential energy, so that the clamping head can push the workpiece out of the first slide groove into the unloading track for unloading.
[0029] In summary, this application has at least one of the following beneficial effects:
[0030] 1. Multiple workpieces to be processed are placed in the storage track for storage, so that they can fall from the bottom in sequence. The transfer piece can push the parts from the bottom of the storage track to the designated position of the lower die in sequence. When the upper die is driven down by the first driving source, the workpieces to be processed can be stamped. The processed workpieces can slide from the unloading track, and the transfer piece continues to transport the next workpiece to be processed, realizing automatic loading and unloading of the stamping tooling, eliminating the need for manual loading and unloading, and improving work efficiency.
[0031] 2. By setting a movable limit pin, the limit pin can limit the workpiece to be processed, cooperate with the transfer piece to clamp the workpiece to be processed, and allow the workpiece to pass through and be unloaded after the workpiece is processed;
[0032] 3. When the transfer part moves and the limit pin clamps the workpiece to be processed, the elastic part compresses to store elastic potential energy. When the limit pin drops, the elastic part releases the elastic potential energy, so that the clamping head can push the workpiece out of the first slide groove into the unloading track for unloading.

[0039] The following is combined with Figure 1-5 This application is described in further detail.
[0040] The embodiment of the present application discloses a stamping tool, referring to Figure 1 and Figure 2 The stamping tooling includes a machine 1, a loading mechanism, an upper die 16, a lower die 11, a material storage track 17, a support base 12, and a transfer piece arranged on the machine 1. The upper die 16 is located on top of the lower die 11. An L-shaped bracket is vertically fixed to the top surface of the machine 1. The upper die 16 is slidably connected to the bracket. A first drive source 14 is fixed to the bracket to drive the upper die 16 to move vertically. The first drive source 14 is specifically a hydraulic cylinder or a pneumatic cylinder. A punching knife 161 is fixed to the bottom of the upper die 16, which can punch holes in the workpiece to be processed located on the lower die 11.
[0041] Reference Figure 2 and Figure 3 The lower die 11 and the support base 12 are bolted to the top of the machine platform 1 and arranged side by side and in contact with each other. A first chute 111 is provided on the top surface of the lower die 11, and a second chute 121 is provided on the top surface of the support base 12. The first chute 111 runs through both ends of the lower die 11, and the second chute 121 runs through both sides of the support base 12. One end of the first chute 111 is connected to the second chute 121 and the bottom wall is flush with each other. The other end is provided with a downwardly inclined slope 115, so that the workpiece to be processed can enter the first chute 111 from the second chute 121 for processing. After processing, it can slide down the slope 115 and enter the unloading track 18.
[0042] The storage track 17 is fixed to the support base 12 by bolts, and a channel for storing and moving the workpieces to be processed is provided between the upper and lower ends of the storage track 17, and the bottom of the channel is a discharge port 171. The workpieces to be processed that fall from the discharge port 171 can enter the second chute 121 for movement.
[0043] Reference Figure 1 and Figure 3 The transfer piece is a movable plate 13, which is in the shape of an elongated strip. Since the stainless steel hook of the present application is arc-shaped, the cross-section of the movable plate 13 can be set to an arc-shaped shape, and the bottom walls of the first chute 111 and the second chute 121 are also arc-shaped surfaces. The height of the workpiece to be processed, that is, the thickness, is greater than the thickness of the movable plate 13, or the distance from the top surface of the movable plate 13 to the inner bottom wall of the second chute 121 is less than or equal to the thickness of one workpiece to be processed, so that when the movable plate 13 moves, it can only push one workpiece to be processed to move. And in the process of the movable plate 13 pushing the workpiece to be processed to the specified position, the movable plate 13 is always partially located at the bottom of the discharge port 171, and the distance between the movable plate 13 and the discharge port 171 is less than the height of one workpiece to be processed, so that the movable plate 13 limits the workpiece to be processed at the discharge port 171 from falling and is driven to move by the movable plate 13.
[0044] Reference Figure 1 and Figure 3A second driving source 15 is also fixed to the machine 1. The second driving source 15 is a pneumatic cylinder or a hydraulic cylinder, and its output end is fixedly connected to the movable plate 13, thereby driving the movable plate 13 to move. Two sliding holes 116 are provided on the top surface of the first slide 111. The line connecting the two sliding holes 116 is perpendicular to the moving direction of the movable plate 13. A limit pin 114 is slidably connected in the sliding hole 116. When the movable plate 13 pushes the workpiece to be processed to the limit pin 114, the limit pin 114 can clamp the workpiece with the movable plate 13, thereby fixing the position of the workpiece to be processed so that it can be punched by the upper die 16.
[0045] Reference Figure 3 and Figure 4 The movable plate 13 has a mounting slot 131 at one end near the stop pin 114. A clamping head 132 is slidably connected within the mounting slot 131. An elastic member 133, which is a spring, is connected between the clamping head 132 and the inner wall of the mounting slot 131, away from the opening. When the movable plate 13 pushes the workpiece to be processed to the stop pin 114, the clamping head 132 moves and compresses the elastic member 133. When stamping is completed, the two stop pins 114 can retract into the sliding hole 116. Under the elastic force of the elastic member 133, the clamping head 132 can push the workpiece to the inclined surface 115, and then slide into the unloading track 18 for unloading.
[0046] Reference Figure 3 and Figure 5 The lower mold 11 is hollow, with an air cavity formed in the middle. One end of a limit pin 114 penetrates into the air cavity, and a pneumatic plate 113 that slides within the air cavity is fixed thereto. The pneumatic plate 113 and the side wall of the lower mold 11 are adapted to be slidably connected. Two air pipes 112 are connected to the side wall of the lower mold 11. The two air pipes 112 are respectively connected to the spaces on both sides of the pneumatic plate 113. By sequentially inflating the two air pipes 112, the pneumatic plate 113 can be driven to move back and forth, thereby achieving the movement of the limit pin 114. In other embodiments of the present application, only one limit air pipe 112 can be provided, and the pneumatic plate 113 can be driven to move back and forth by switching between inflation and suction.
[0047] The implementation principle of a stamping tool in an embodiment of the present application is as follows: when in use, multiple workpieces to be processed can be placed in the storage track 17 for storage at the same time, so that the workpieces to be processed can fall from the discharge port 171 in turn, and the transfer part can push the parts falling from the discharge port 171 to the specified position of the lower mold 11 in turn, and clamp and fix them through the limit pin 114 and the movable plate 13. When the upper mold 16 is driven down by the first driving source 14, the workpiece to be processed can be stamped. The processed workpiece can slide from the discharge track 18 through the elastic force of the elastic part 133, and the transfer part continues to transport the next workpiece to be processed, thereby realizing automatic loading and unloading of the stamping tool, eliminating the need for manual automatic loading and unloading, and improving work efficiency.
[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
