Description

Technical Field

[0001] This invention relates to the field of hardware processing, and more specifically to a hardware stamping die. Background Technology

[0002] Stamping is a mechanical processing technology that uses stamping dies mounted on a stamping machine to apply pressure to materials, causing material separation or plastic deformation, thereby obtaining the desired stamped parts. It separates waste material from raw materials or workpieces along a closed shape and obtains the required holes in the metal disc to be processed. These are basically stamping and punching processes.

[0003] A Chinese patent publication number (CN114850320A) discloses a metal stamping die, comprising a lower die base. Hydraulic push rods are fixedly connected to the four corners of the upper surface of the lower die base. An upper die base is fixedly connected to the top of each hydraulic push rod. A punch is fixedly connected to the bottom surface of the upper die base near the front. A die is fixedly connected to the upper surface of the lower die base corresponding to the punch. This device structure not only automatically ejects sheet metal parts via a stop block during punch lifting, eliminating the need for frequent manual removal and reducing labor intensity while ensuring worker safety, but also sweeps away metal debris adhering to the die after ejecting the sheet metal part. Furthermore, it blows away the metal debris using a spring airbag and removes some heat from the die through airflow, reducing wear on the die from metal debris, extending its service life, and ensuring the quality of subsequent sheet metal parts.

[0004] The above-mentioned stamping dies also have the following problems when in use: The above-mentioned stamping dies handle the debris after the processing is completed, but the debris cannot be handled in time during processing. The debris may fly everywhere due to the impact force during processing, which may accidentally injure the operators.

[0005] Therefore, it is necessary to invent a metal stamping die to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a metal stamping die to solve the problem mentioned in the background art that the stamping die can only handle the debris after processing is completed, but cannot handle the debris in time during processing. The debris may fly everywhere due to the impact force during processing, which may accidentally injure the workers who are operating the die.

[0013] Preferably, the drilling device consists of a drive unit and a drill bit, with the top of the drive unit fixedly connected to the bottom of the movable plate, and the output shaft of the drive unit being drivenly connected to the drill bit.

[0014] Preferably, the lower mold base is frustum-shaped, and the bottom of the lower mold base is fixedly connected to the upper end of the connecting rod, and the lower end of the connecting rod is fixedly connected to the umbrella-shaped inclined surface at the top of the debris collection frame, and there is a certain gap between the bottom surface of the lower mold base and the umbrella-shaped inclined surface at the top of the debris collection frame.

[0015] The lower mold base has a groove inside that is equal to the diameter of the disc to be processed. The depth of the groove is greater than the thickness of the disc to be processed. A punching groove that penetrates the bottom of the lower mold base is also provided below the groove. The diameter of the punching groove is greater than the diameter of the drill bit of the drilling device.

[0016] Four equidistant blocks are fixedly connected above the annular groove inside the lower mold base, and the distance between the opposite surfaces of two opposing equidistant blocks is equal to the diameter of the annular groove inside the lower mold base.

[0017] Preferably, the splash-proof mechanism includes:

[0018] The splash shield is composed of an annular plate with an open bottom. The top of the splash shield is fixedly connected to the bottom of the movable plate. The top of the splash shield is also fixedly sleeved on the outer ring of the driving device of the drilling device. An annular movable groove is provided inside the annular plate of the splash shield.

[0019] Splash shield 2 is composed of a ring plate that runs vertically through the top and bottom. The outer surface of splash shield 2 is in contact with and movably connected to the inner wall of the movable groove 1 inside splash shield 1. The bottom of splash shield 2 is provided with an inclined surface with the same inclination as the umbrella-shaped inclined surface at the top of the debris collection frame. The weight of splash shield 2 is greater than the deformation force of the spring.

[0020] There are two protrusions, which are fixedly connected to the top left and right sides of the second ring plate of the splash shield in a symmetrical manner. The protrusions can move inside the long strip-shaped notches reserved on both sides of the first splash shield.

[0021] Preferably, the ejection mechanism includes:

The splash guard forms a closed area, so that the debris generated by the drilling device during the punching and drilling of the disc will not fly everywhere. During the descent of the splash guard, the inner groove of the splash guard pushes the push rod downward, so that the disc descends smoothly into the processing groove in the lower die base, avoiding the impact force of the drilling device during processing that causes the disc to shift and affect the processing accuracy.

[0031] When the cylinder moves upward, causing the drilling device to leave the lower mold base, the splash guard moves upward, causing the slot to leave the ejector rod. At this time, the spring loses pressure and pushes the ejector rod upward. The ejector rod moves upward and pushes out the processed round piece, which is convenient for subsequent part removal.

[0042] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] This invention provides, for example Figure 1-7 The illustrated metal stamping die includes a scrap collection frame 1, a column 2 fixedly connected to the top wall of the scrap collection frame 1, and the top of the column 2 fixedly connected to a top plate 3. A cylinder 4 is embedded in the top plate 3, a movable plate 5 is fixedly connected to the movable end of the cylinder 4, and a drilling device 6 is fixedly connected to the bottom of the movable plate 5. The top wall of the scrap collection frame 1 is fixedly connected to a lower die base 7 via a connecting rod 8. The die also includes:

[0044] The splash protection mechanism 9 has a splash cover 901 fixedly connected to the bottom of the movable plate 5, and a splash cover 902 is movably sleeved on the inner ring of the splash cover 901.

[0045] The ejection mechanism 10 has a movable groove 1001 inside the lower mold base 7, and an ejector rod 1002 is movably connected inside the movable groove 1001.

[0046] The stabilizing mechanism 11 has a positioning rod 1101 fixedly connected to the top of the debris collection frame 1, and the positioning rod 1101 matches the positioning groove 1102.

[0047] The interior of the debris collection frame 1 is a hollow area, and the top of the debris collection frame 1 is provided with an inverted umbrella-shaped inclined surface. A discharge port is opened at the center of the umbrella-shaped inclined surface. The discharge port is connected to the hollow area inside the debris collection frame 1, so that the debris generated during processing can slide into the hollow area inside the debris collection frame 1 through the umbrella-shaped inclined surface and the discharge port.

[0048] The movable plate 5 is movably sleeved on the outer ring of the four symmetrically distributed columns 2, and the top of the movable plate 5 is fixedly connected to the end of the movable part of the cylinder 4, and the bottom of the movable plate 5 is fixedly connected to the top of the drilling device 6, so as to ensure that the movable plate 5 is more stable when the cylinder 4 descends.

[0049] The drilling device 6 consists of a drive unit and a drill bit. The top of the drive unit is fixedly connected to the bottom of the movable plate 5. The output shaft of the drive unit is connected to the drill bit for punching and drilling.

[0050] The lower mold base 7 is in the shape of a frustum, and the bottom of the lower mold base 7 is fixedly connected to the upper end of the connecting rod 8. The lower end of the connecting rod 8 is fixedly connected to the top umbrella-shaped inclined surface of the debris collection frame 1. There is a certain gap between the bottom surface of the lower mold base 7 and the top umbrella-shaped inclined surface of the debris collection frame 1. The debris generated during processing falls into the interior of the debris collection frame 1 through this gap, which is convenient for subsequent unified collection.

[0051] The lower die base 7 has a groove inside that is equal to the diameter of the disc to be processed. The depth of the groove is greater than the thickness of the disc to be processed. A punching groove that penetrates the bottom of the lower die base 7 is also provided below the groove. The diameter of the punching groove is greater than the diameter of the drill bit of the drilling device 6. This makes it easier to limit the disc to be processed and avoid the impact force during processing causing the disc to shift and affecting the processing accuracy.

[0052] Four equidistant limit blocks 12 are fixedly connected above the annular groove inside the lower mold base 7. The distance between the opposite faces of two opposite limit blocks 12 is equal to the diameter of the annular groove inside the lower mold base 7, which is used for positioning and placing the circular piece to be processed.

[0053] The splash-proof mechanism 9 includes:

[0054] The splash shield 901 and the movable groove 904 are composed of an annular plate with an open bottom. The top of the splash shield 901 is fixedly connected to the bottom of the movable plate 5. The top of the splash shield 901 is also fixedly sleeved on the outer ring of the drive device of the drilling device 6. The annular movable groove 904 is opened inside the annular plate of the splash shield 901.

[0055] Splash shield 2 902 is composed of annular plates that run vertically through the top and bottom. The outer surface of splash shield 2 902 is in contact with and movably connected to the inner wall of movable groove 904 inside splash shield 1 901. The bottom of splash shield 2 902 is provided with a slope that is equal in inclination to the umbrella-shaped inclined surface at the top of debris collection frame 1. The weight of splash shield 2 902 is greater than the deformation force of spring 1003. Splash shield 1 901 and splash shield 2 902 can form a closed area to prevent debris from splashing.

[0056] There are two protrusions 903, which are symmetrically fixedly connected to the top left and right sides of the annular plate of splash shield 902. The protrusions 903 can move inside the long strip-shaped notches reserved on both sides of splash shield 901 to ensure the stability of the movable connection between splash shield 901 and splash shield 902.

[0057] The ejection mechanism 10 includes:

[0058] There are two movable slots 1001, and the two movable slots 1001 are symmetrically arranged on both sides of the interior of the lower mold base 7.

[0059] There are two ejector rods 1002, and the ejector rods 1002 are inverted "L" shape. The ejector rods 1002 fit and are movably connected to the inner wall of the movable groove 1001. The vertical rod of the ejector rod 1002 can pass through the groove reserved in the lower mold base 7, and the horizontal rod of the ejector rod 1002 extends to the outside of the lower mold base 7. During the descent of the splash guard 902, it abuts against the ejector rod 1002, so that the vertical rod of the ejector rod 1002 is completely retracted into the movable groove 1001, which will not affect the processing of the circular piece to be processed inside the groove of the lower mold base 7.

[0060] Spring 1003, with its two ends fixedly connected to the inner wall of push rod 1002 and movable groove 1001 respectively, is used for the reset movement of push rod 1002, and pushes out the processed disc as splash shield 902 rises.

[0061] There are two slots 1004, which are located at the bottom of the second splash shield 902. The slots 1004 can contact the end of the ejector rod 1002 located outside the lower mold base 7, and are used to hold the ejector rod 1002 during the descent of the second splash shield 902.

[0062] Stabilizing agency 11 includes:

[0063] There are two positioning rods 1101, and the two positioning rods 1101 are symmetrically distributed on both sides of the lower mold base 7. One end of the positioning rod 1101 is fixedly connected to the top wall of the debris collection frame 1.

[0064] The positioning groove 1102 is formed inside the splash shield 902. The positioning rod 1101 matches the positioning groove 1102 to prevent the splash shield 902 from shifting.

[0065] Working principle: When using a metal stamping die, the disc to be processed is first placed in the defined groove inside the lower die base 7. At this time, the spring 1003 pushes the ejector rod 1002 to the ejected state, and the disc is completely inserted into the defined groove. At the same time, the disc will not move under the limit of the limit block 12. The cylinder 4 is activated to drive the movable plate 5 to descend, which in turn drives the drilling device 6 and the splash guard 901 and splash guard 902 to descend. The bottom of the splash guard 902 contacts the umbrella-shaped inclined surface at the top of the debris collection frame 1, forming a closed area. At the same time as the bottom of the splash guard 902 contacts the umbrella-shaped inclined surface at the top of the debris collection frame 1, the slot 1004 at the bottom of the splash guard 902 abuts against the ejector rod 1002 and moves downward. The top part of the ejector rod 1002 descends (refer to...). Figure 7This causes the disc to fall into the recessed groove inside the lower mold base 7, preventing it from shifting during subsequent processing. At this time, the cylinder 4 continues to descend, driving the drilling device 6 and the splash guard 901 to continue descending. Because the splash guard 901 and the splash guard 902 are movably connected, the continuous descent of the splash guard 901 will not affect the previously enclosed area. The drilling device 6 is activated, and the drill bit in the drilling device 6 processes the disc inside the lower mold base 7. The debris generated during processing is blocked inside the enclosed area formed by the splash guard 901 and the splash guard 902, and will not fly around. At the same time, the falling debris slides into the hollow area inside the debris collection frame 1 through the umbrella-shaped inclined surface and the discharge port, which is convenient for subsequent unified collection.

[0066] After processing is completed, the cylinder 4 is started to drive the drilling device 6 and the splash guards 901 and 902 to rise, releasing the closed area. The splash guard 902 then leaves the top of the debris collection frame 1. At this time, the ejector rod 1002 loses the pressure of the splash guard 902, and the spring 1003 resets and pushes the ejector rod 1002 to move upward to eject the processed round piece, which makes it convenient for the staff to pick up the parts later.

[0067] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
