Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, specifically a punching device for a precision hardware stamping die. Background Technology

[0002] Precision hardware specifically refers to the hardware processing category within the hardware industry that requires high precision, including precision plastic hardware, precision stamping hardware, precision turning hardware, etc., which are widely used in industries such as electronics, watches, and aerospace. Among them, punching equipment is a device that punches holes in hardware parts.

[0003] When processing precision hardware, existing punching equipment is often inefficient. If the hardware is square or round, the punch head is too small to punch both sides of the inner wall at once. Therefore, after punching one side, the operator must remove the precision hardware from the equipment and then manually flip it over and put it back into the punching equipment to punch the other side. This operation is time-consuming and labor-intensive. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a punching device for precision metal stamping dies to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a punching device for a precision metal stamping die, comprising a base, a second hydraulic cylinder installed at the bottom inside the base, and a support seat connected to the output end of the second hydraulic cylinder; a second motor installed on the outer surface of the support seat, and a conveying wheel connected to the output end of the second motor; brackets connected to both sides of the top of the base, and a first motor installed on one side of the bracket; rollers connected to the output end of the first motor and inside the bracket; a turntable connected to one side of the rollers; a first bevel gear and a second bevel gear connected inside the turntable, and a slot opened at one end of the second bevel gear; a flat threaded disc provided on one side of the first bevel gear, and a slide connected to one side of the flat threaded disc; a clamping wheel connected inside the slide; and a guide groove opened on one side of the turntable.

[0006] By adopting the above technical solution, when precision hardware parts are passed through the turntable, the second bevel gear can be manually rotated by inserting the sliding lever wrench into the slot. At this time, the second bevel gear meshes with the first bevel gear, causing the first bevel gear to drive the flat threaded disc to rotate. After the flat threaded disc rotates, it works with the guide groove to guide the slide block, thereby causing the slide block to drive the clamping wheel to move towards or away from the center of the turntable. This facilitates the clamping of precision hardware parts of different sizes, avoids the precision hardware parts rolling inside the turntable during the flipping process, which affects the flipping accuracy, and the clamping wheel can rotate to reduce the contact between the precision hardware parts and the slide block. Wear between the precision hardware and the turntable; when it is necessary to flip the precision hardware, the second hydraulic cylinder drives the support base and the conveyor wheel to move down to avoid the precision hardware, so as to prevent the precision hardware from hitting the conveyor wheel or the support base when flipping. Then, the first motor output drives the roller to rotate, and the roller rotates to drive the turntable to rotate, so that the precision hardware passing through the turntable is driven to rotate together. Then, the second hydraulic cylinder drives the support base and the conveyor wheel to move up, and the conveyor wheel supports the precision hardware. Subsequently, the second motor output drives the conveyor wheel to rotate to transport the precision hardware, which facilitates continuous drilling and loading and unloading.

[0007] Furthermore, there are two of each of the first motor, turntable, flat threaded disc and first bevel gear, and two sets of each of the idler roller, slide block, clamping wheel, guide groove, second bevel gear and slot.

[0008] By adopting the above technical solution, the precision hardware can be flipped regardless of whether it is on the left or right side, without having to retract the precision hardware before flipping it, thus improving efficiency.

[0009] Furthermore, the second bevel gears and the slots are grouped into sets of four, and the two sets of second bevel gears mesh with the two first bevel gears respectively.

[0010] By adopting the above technical solution, the staff can manually rotate the second bevel gear by inserting the sliding lever wrench into the slot. At this time, the second bevel gear meshes with the first bevel gear, causing the first bevel gear to drive the flat threaded disc to rotate.

[0011] Furthermore, the slide block is threadedly connected to the planar threaded disc, and the slide block is slidably connected to the guide groove.

[0012] By adopting the above technical solution, the flat threaded disc rotates and guides the slide block with the guide groove, thereby causing the slide block to drive the clamping wheel to move towards or away from the center of the turntable, thus facilitating the clamping of precision hardware parts of different sizes.

[0013] Furthermore, multiple second motors and conveyor wheels are provided, and the multiple second motors and conveyor wheels are distributed at equal intervals.

[0014] By adopting the above technical solution, after the second motor starts, the output end drives the conveyor wheel to rotate, thereby displacing the precision hardware parts so as to continuously punch out multiple holes on the top of the precision hardware parts.

[0015] Furthermore, a top frame is connected to the middle of the top of the base, and a first hydraulic cylinder is installed on the top of the top frame, with a punching head connected to the output end of the first hydraulic cylinder.

[0016] By adopting the above technical solution, after the first hydraulic cylinder is started, the output end drives the punch head to move up and down repeatedly, thereby punching the precision hardware parts.

[0017] Furthermore, a collection box extends through the outer surface of the base, a third motor is installed below the outer surface of the support base, and a belt conveyor is connected to the output end of the third motor.

[0018] By adopting the above technical solution, during the punching process, the workers can drive the belt conveyor to rotate forward or reverse through the third motor, thereby sending the waste material that falls into the support base during punching into the collection box. When the collection box is full, the workers can pull the collection box out of the base and dump the waste material to the designated location. After dumping, the workers can put the collection box back in its original position.

[0019] Furthermore, the collection box is detachably connected to the base.

[0020] By adopting the above technical solution, when the collection box is full, the staff can pull the collection box out from the base, dump the waste to the designated location, and then put the collection box back in its original position.

[0021] Furthermore, there are two collection boxes, which are located on the lower sides of the belt conveyor, respectively.

[0022] By adopting the above technical solution, when one collection box is full of waste, the staff can reverse the belt conveyor so that the waste can be collected through another collection box, thus extending the cleaning interval.

[0023] In summary, the present invention has the following main advantages:

[0024] 1. This utility model, through the arrangement of rollers, turntable, support base, and conveyor wheel, allows for the following mechanism: when a precision hardware part needs to be flipped, the second hydraulic cylinder drives the support base and conveyor wheel to move downwards to avoid the precision hardware part, preventing it from hitting the conveyor wheel or support base during flipping. Then, the output of the first motor drives the rollers to rotate, which in turn drives the turntable to rotate, causing the precision hardware part passing through the turntable to rotate as well. Subsequently, the second hydraulic cylinder drives the support base and conveyor wheel to move upwards, supporting the precision hardware part with the conveyor wheel. The second motor then drives the conveyor wheel to rotate and transport the precision hardware part, facilitating continuous drilling and loading / unloading; it also facilitates automatic flipping, saving time and effort in operation.

[0025] 2. This utility model, through the arrangement of a flat threaded disc, a slide block, a clamping wheel, a guide groove, a first bevel gear, a second bevel gear, and a slot, allows precision hardware parts to pass through the turntable. By inserting a sliding lever wrench into the slot, the second bevel gear can be manually rotated. At this time, the second bevel gear meshes with the first bevel gear, causing the first bevel gear to drive the flat threaded disc to rotate. After the flat threaded disc rotates, it works with the guide groove to guide the slide block, thereby causing the slide block to drive the clamping wheel to move towards or away from the center of the turntable. This facilitates the clamping of precision hardware parts of different sizes, preventing the precision hardware parts from rolling inside the turntable during the flipping process and affecting the flipping accuracy. Furthermore, the clamping wheel can rotate, reducing wear between the precision hardware parts and the slide block and turntable. It is convenient for clamping precision hardware parts of different sizes and prevents the precision hardware parts from rolling inside the turntable during the flipping process, thus avoiding affecting the flipping accuracy.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] Example 1:

[0034] A punching device for a precision metal stamping die, such as Figures 1-4 As shown, the system includes a base 1, with a second hydraulic cylinder 16 installed inside the lower part of the base 1. The output end of the second hydraulic cylinder 16 is connected to a support base 17, and a second motor 18 is installed on the outer surface of the support base 17. The output end of the second motor 18 is connected to a conveyor wheel 19. Multiple second motors 18 and conveyor wheels 19 are provided, and the multiple second motors 18 and conveyor wheels 19 are equidistantly distributed. After the second motor 18 is started, its output end drives the conveyor wheel 19 to rotate, thereby displacing the precision hardware part so as to continuously punch multiple holes in the top of the precision hardware part; the top of the base 1 Both sides are connected to brackets 5. A first motor 6 is installed on one side of bracket 5. Rollers 7 are connected to the output end of the first motor 6 and inside the bracket 5. A turntable 8 is connected to one side of the roller 7. The operator drives the roller 7 to rotate through the first motor 6. The rotation of the roller 7 drives the turntable 8 to rotate, thereby causing the precision hardware parts passing through the turntable 8 to rotate together. The turntable 8 is equipped with a first bevel gear 13 and a second bevel gear 14. One end of the second bevel gear 14 has a slot 15. The second bevel gear 14 and the slot 15 are in groups of four. The bevel gear 14 meshes with two first bevel gears 13. A flat threaded disc 9 is provided on one side of the first bevel gear 13, and a slide block 10 is connected to one side of the flat threaded disc 9. The slide block 10 is threadedly connected to the flat threaded disc 9. A clamping wheel 11 is connected inside the slide block 10. A guide groove 12 is provided on one side of the turntable 8, and the slide block 10 is slidably connected to the guide groove 12. There are two of each of the first motor 6, turntable 8, flat threaded disc 9, and first bevel gear 13. The idler roller 7, slide block 10, clamping wheel 11, guide groove 12, second bevel gear 14, and slot 15 are also provided. There are two sets. The operator can manually rotate the second bevel gear 14 by inserting the sliding lever wrench into the slot 15. At this time, the second bevel gear 14 meshes with the first bevel gear 13, causing the first bevel gear 13 to drive the flat threaded disk 9 to rotate. After the flat threaded disk 9 rotates, it cooperates with the guide groove 12 to guide the slide 10, thereby causing the slide 10 to drive the clamping wheel 11 to move towards or away from the center of the turntable 8. This makes it easier to clamp precision hardware parts of different sizes and avoids the precision hardware parts rolling in the turntable 8 during the flipping process, which affects the flipping accuracy.

[0035] See Figure 1In the above embodiment, a top frame 2 is connected to the middle of the top of the base 1, and a first hydraulic cylinder 3 is installed on the top of the top frame 2. The output end of the first hydraulic cylinder 3 is connected to a punch head 4. After the first hydraulic cylinder 3 is started, the output end drives the punch head 4 to move up and down repeatedly, thereby punching the precision hardware parts.

[0036] Example 2:

[0037] Based on the above embodiment one, in order to facilitate the collection of waste and reduce the difficulty of cleaning for staff, the following settings are now implemented.

[0038] See Figure 1 In the above embodiment, a collection box 22 is passed through the outer surface of the base 1. The collection box 22 is detachably connected to the base 1. There are two collection boxes 22, which are located on the lower sides of the belt conveyor 21. A third motor 20 is installed on the lower surface of the support base 17. The output end of the third motor 20 is connected to the belt conveyor 21. During the punching process, the operator can drive the belt conveyor 21 to rotate forward or backward through the third motor 20, so as to send the waste material that falls into the support base 17 during punching into the collection box 22. When the collection box 22 is full, the operator can pull the collection box 22 out of the base 1 and dump the waste material to a designated location. After dumping, the operator puts the collection box 22 back in its original position.

[0039] The implementation principle of this utility model is as follows: First, the operator drives the support base 17 and the conveyor wheel 19 to move down and avoid the precision hardware parts through the second hydraulic cylinder 16; then, the operator passes the precision hardware parts to be punched through the two turntables 8; then, the operator inserts the sliding lever wrench into the slot 15 to manually rotate the second bevel gear 14. At this time, the second bevel gear 14 meshes with the first bevel gear 13, causing the first bevel gear 13 to drive the flat threaded disk 9 to rotate. After the flat threaded disk 9 rotates, it cooperates with the guide groove 12 to guide the slide block 10, thereby causing the slide block 10 to move and clamp. The wheel 11 is displaced towards or away from the center of the turntable 8, thus facilitating the clamping of precision hardware parts of different sizes and preventing the precision hardware parts from rolling within the turntable 8 during the flipping process, which would affect the flipping accuracy. Then, the operator drives the support base 17 and the conveyor wheel 19 to move upward through the second hydraulic cylinder 16, so that the precision hardware parts are supported by the conveyor wheel 19. Subsequently, the conveyor wheel 19 can be driven to rotate by the output end of the second motor 18 to transport the precision hardware parts. If the size of the precision hardware parts to be punched later remains unchanged, no readjustment is required, and they can be used directly.

[0040] The operator starts the first hydraulic cylinder 3 and the second motor 18. After the first hydraulic cylinder 3 starts, the output end drives the punch head 4 to move up and down repeatedly, thereby punching holes in the precision hardware. After the second motor 18 starts, the output end drives the conveyor wheel 19 to rotate, thereby displacing the precision hardware so that multiple holes can be punched continuously on the top of the precision hardware. The clamping wheel 11 can rotate to reduce the wear between the precision hardware and the slide 10 and the turntable 8.

[0041] When it is necessary to flip the precision hardware, the operator shuts off the first hydraulic cylinder 3 and the second motor 18. Then, the operator drives the support base 17 and the conveyor wheel 19 to move down through the second hydraulic cylinder 16 to avoid the precision hardware, so as to prevent the precision hardware from hitting the conveyor wheel 19 or the support base 17 when flipping. Then, the operator drives the roller 7 to rotate through the first motor 6. After the roller 7 rotates, it drives the turntable 8 to rotate, so that the precision hardware passing through the turntable 8 is driven to rotate together. Then, the second hydraulic cylinder 16 drives the support base 17 and the conveyor wheel 19 to move up, and the conveyor wheel 19 supports the precision hardware to facilitate punching on other surfaces of the precision hardware.

[0042] During the punching process, the worker can drive the belt conveyor 21 to rotate forward or reverse via the third motor 20, thereby sending the waste material that falls into the support base 17 during punching into the collection box 22. When one collection box 22 is full of waste material, the worker can reverse the belt conveyor 21, thereby collecting the waste material through the other collection box 22 and extending the cleaning interval. When the collection box 22 is full, the worker can pull the collection box 22 out of the base 1 and dump the waste material to the designated location. After dumping, the worker can put the collection box 22 back in its original position.
