Description

Technical Field

[0001] The invention relates to the technical field of punching and punching, in particular to a punching device for punching an annular workpiece. Background Art

[0002] Punching refers to a processing method of opening long holes, square holes, round holes, perforated plate meshes and triangular holes on hardware workpieces to meet different needs, so as to be suitable for different production processes and assembly operations; after searching, the Chinese invention patent with publication number CN117123675B discloses a punching device for processing thin-walled annular hardware, which drives two worms to rotate through the rotation of a motor, and drives the worm wheel located on the processing roller to rotate through the rotation of the worm. Since the spiral directions of the teeth on the worm are opposite, the two processing rollers rotate in opposite directions to roll the side walls of the hardware. Through the mold set on the outer peripheral surface of the processing roller, when the two processing rollers roll against each other, the punch on the mold cooperates with the punching hole to open a hole in the side wall of the hardware.

[0003] During use, the device for punching annular workpieces uses two processing rollers to rotate symmetrically, and the side walls of the annular hardware can be punched through the molds set on the two processing rollers. However, this punching method of the punching device can only adapt to thin-walled annular hardware. Since the molds on the two processing rollers rotate, the annular movement of the molds and the rotation of the annular hardware are at different axes. When punching an annular workpiece of a certain thickness, the molds cannot be removed from the punched holes in the first time, which can easily cause damage to the holes or damage to the molds. The function of punching annular hardware of different thicknesses is lacking, which reduces the practicality of the punching device. Summary of the invention

By setting the supporting member 7, the position of the punching of the annular workpiece body 4 can be supported, which not only avoids deformation of the workpiece caused by high-intensity punching movement, but also facilitates the discharge of waste materials from the punching process.

[0042] The driving assembly 5 includes a driving roller 51 that is in contact with the inner surface of the annular workpiece body 4 and a rotating member 56 for rotating the driving roller 51;

[0043] The driving roller 51 is tightly fitted to the inner surface of the annular workpiece body 4, and the driving roller 51 is driven to rotate by the rotating member 56, so as to meet the punching work at different positions of different annular workpiece bodies 4. The rotating member 56 includes but is not limited to a motor for driving the driving roller 51 to rotate.

[0044] The punching assembly 6 includes a punching member 63 for punching the annular workpiece body 4 and an electric cylinder 61 for driving the punching member 63 up and down;

[0045] The electric cylinder 61 drives the punching member 63 to reciprocate up and down, so that the annular workpiece body 4 can be punched.

[0047] The electric cylinder 61 is connected to an external power supply and a control switch, and is used to drive the U-shaped frame 62 to move up and down. The up and down movement of the U-shaped frame 62 can drive the punching member 63 to move up and down, thereby forming a stamping and punching process of the annular workpiece body 4.

[0048] See attached Figure 3 and Figure 4 The driving assembly 5 includes a movable frame 52 fixed to the top of the mounting seat 1, and the interior of the movable frame 52 is slidably connected to an adjusting block 53 in an up-and-down sliding manner, one end of the driving roller 51 is rotatably connected to the interior of the adjusting block 53, and an elastic rubber tube 54 is fixedly connected to the outer surface of the driving roller 51. The top of the movable frame 52 is threadedly connected to a screw rod 55 for adjusting the adjusting block 53 up and down, and the bottom end of the screw rod 55 is rotatably connected to the top of the adjusting block 53;

[0049] By manually controlling the rotation of the screw rod 55, the adjusting block 53 can be driven to move up and down, and the up and down movement of the adjusting block 53 can adjust the height of the driving roller 51, which is not only convenient for the staff to disassemble, assemble and replace the annular workpiece body 4 that needs punching processing, but also convenient for adjusting the pressure of the driving roller 51 on the annular workpiece body 4, thereby improving the convenience and orderliness of subsequent rotation drive. An elastic rubber tube 54 is fixedly connected to the outer surface of the driving roller 51, so that the friction between the driving roller 51 and the annular workpiece body 4 can be increased through the elastic rubber tube 54, thereby improving the smoothness of subsequent rotation drive.

[0050] See attached Figure 6 The supporting member 7 includes a supporting roller 71 fixed to the front of the support frame 2, an inclined material guide groove 72 is provided inside the supporting roller 71, and a lower hopper 73 is installed at the front opening of the supporting roller 71, and a through hole 74 is provided on the outer surface of the supporting roller 71;

[0051] The supporting roller 71 is provided to support the position of the punching holes, thereby preventing the annular workpiece body 4 from being deformed when the punching assembly 6 punches the annular workpiece body 4. An inclined material guide groove 72 is provided inside the supporting roller 71, which not only facilitates the collection of waste materials after punching, but also allows the collected waste materials to be discharged in an orderly manner, thereby improving the convenience of subsequent waste recycling and processing.

[0052] See attached Figure 4The rotating member 56 includes a connecting rod 561 fixed to the telescopic end of the electric cylinder 61, a gear plate frame 562 is fixedly connected to the bottom end of the connecting rod 561, and a gear 564 is fixedly connected to one end of the driving roller 51 through a one-way bearing 563, and the outer surface of the gear 564 is meshed with one side of the gear plate frame 562;

[0053] The toothed plate frame 562 is fixedly connected to the telescopic end of the electric cylinder 61 by a connecting rod 561, so that when the electric cylinder 61 moves up and down, the toothed plate frame 562 can be synchronously driven to move up and down, and the up and down movement of the toothed plate frame 562 can drive the gear 564 to rotate forward and reverse;

[0054] The one-way bearing 563 is fixedly connected to the driving roller 51 through the gear 564, and the outer ring of the one-way bearing 563 is fixedly connected to the gear 564, and the inner ring is fixedly connected to the driving roller 51, so that when the gear plate frame 562 moves downward, the gear 564 will not drive the driving roller 51 to rotate. On the contrary, when the gear plate frame 562 is reset upward, the gear 564 can drive the driving roller 51 to rotate, thereby forming the self-rotation of the annular workpiece body 4;

[0055] It should be noted here that the electric cylinder 61 adopts a cylinder with adjustable telescopic length in the prior art, so that the telescopic length of the electric cylinder 61 can be used to drive the toothed plate frame 562 to move up and down, thereby increasing the rotation angle of its gear 564, and then increasing the rotation angle of its annular workpiece body 4, forming different spacing punching processing.

[0056] Embodiment 2: Based on embodiment 1, the difference is that;

[0059] The electric locking member includes a movable frame 8 fixed to the front of the support frame 2, two guide rods 9 are slidably connected inside the movable frame 8, an electromagnet 10 for magnetically adsorbing the metal annular workpiece body 4 after power is turned on is fixedly connected between one end of the two guide rods 9, and the adsorption end of the electromagnet 10 is set as an arc surface, and two tension springs 11 for elastically resetting the electromagnet 10 are fixedly connected to one side of the movable frame 8;

[0060] The tension spring 11 is provided to pull and reset the electromagnet 10 after it loses power, thereby facilitating the driving component 5 to drive the annular workpiece body 4 to rotate. By energizing the electromagnet 10, the electromagnet 10 can generate a high-strength adsorption force. Through the adsorption force of the electromagnet 10, the electromagnet 10 can be closely fitted and contacted with the inner surface of the annular workpiece body 4, forming the stability of the annular workpiece body 4 after rotation adjustment, thereby improving the stability of its subsequent punching processing.

[0061] Embodiment 3: Based on embodiment 1, the difference is that;

[0062] See attached Figure 7 The punching member 63 includes a rotating roller 631 rotatably connected to the inside of the U-shaped frame 62, and a plurality of punching heads 632 of different models are fixedly connected to the outer surface of the rotating roller 631. One end of the rotating roller 631 extends to the outside of the U-shaped frame 62, and a circular block 633 is fixedly connected to one end of the rotating roller 631.

By sliding the T-shaped latch 634 downward, the T-shaped latch 634 can be inserted into the bayonet at the corresponding position to form a lock, thereby ensuring the stability of the rotating roller 631 after rotation adjustment, and further ensuring the stability of the position conversion of the punching head 632.

[0064] It should be noted that the term "comprises" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article, or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article, or device.
