Numerical control turret punch press for punching forming and its usage method

Abstract

The present invention relates to the technical field of punching presses, and provides a numerical control turret punching press for punching and forming, including a machine body. A punching frame is fixedly connected to the top of the machine body. A first hydraulic push rod is rotatably connected to the inner wall of the top of the punching frame. A punching assembly is movably connected to the bottom of the first hydraulic push rod. Transfer assemblies are movably connected to the left and right sides of the first hydraulic push rod. An adjustment assembly is movably connected to the outer wall of the transfer assembly. A placement plate is movably connected to the outer wall of the adjustment assembly. For this numerical control turret punching press for punching and forming, the compression pad compresses the return spring and drives the vertical rod to move. The vertical rod drives the extrusion plate to move upward. At this time, the cutter moves downward along with the square plate for punching. Since the placement plate moves upward, the original distance from the placement plate to the punching position changes. To avoid over-punching, when the extrusion plate contacts the contact switch, it means that the punching depth of the cutter is sufficient, thus avoiding the effect that the product cannot be used due to over-punching.

Description

Technical Field

[0001] The present invention relates to the technical field of punching presses, and specifically to a numerically controlled turret punching press for punching and forming and a usage method thereof. Background Art

[0002] A numerically controlled turret punching press is a pressure processing equipment for punching and shallow drawing on a sheet. With the development of the times, the products produced by mechanical stamping have high precision and fast production efficiency.

[0003] In the prior art, the downward pressure speed during stamping by a turret punching press will affect the stress between the tool and the sheet. If the downward pressure speed is slow, the cutting force is small, the products produced by stamping will have burrs, and if the stamping depth is not restricted, the sheet will be damaged.

[0004] Therefore, the demand for highly reliable products is urgent. Thus, we have proposed a numerically controlled turret punching press for punching and forming and a usage method thereof, which has the effect of applying an upward force to the sheet to increase the cutting force, fixing the position, and restricting the stamping depth. Summary of the Invention

[0005] The purpose of the present invention is to provide a numerically controlled turret punching press for punching and forming and a usage method thereof to solve the problems raised in the background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions

[0007] A numerically controlled turret punching press for punching and forming, including a machine body. A punching frame is fixedly connected to the top of the machine body. A first hydraulic push rod is rotatably connected to the inner wall of the top of the punching frame. The bottom of the first hydraulic push rod is movably connected to a punching component. A transmission component is fixedly connected to the inner wall of the top of the punching frame. The outer wall of the transmission component is movably connected to an adjustment component. The outer wall of the adjustment component is movably connected to a placement plate. A plug rod is fixedly connected to the bottom of the placement plate.

[0008] Further, the punching component includes a square plate. A tool is fixedly connected to the bottom of the square plate. A return spring is fixedly connected to the bottom of the square plate. One end of the return spring away from the square plate is fixedly connected to a pressure pad. A vertical rod is fixedly connected to the top of the pressure pad. An extrusion plate is fixedly connected to the top of the vertical rod. A contact switch is fixedly connected to the outer wall of the square plate.

[0009] Further, the transmission component includes a cylinder. A second hydraulic push rod is fixedly connected to the top of the cylinder. A circular ring layer is provided on the outer wall of the cylinder. A gear is meshed with the outer wall of the circular ring layer. The teeth on the outer wall of the gear are meshed with a belt.

[0010] Further, the adjustment component includes a rotating wheel. Both the left and right sides of the rotating wheel are fixedly connected with rotating shafts. The outer wall of the rotating shaft is fixedly connected with a turntable. A sliding groove is formed inside the turntable. A slider is slidably connected to the inner wall of the sliding groove. A spiral spring is fixedly connected to the outer wall of the slider. A linkage rod is hinged to the outer wall of the slider. A sliding plate is hinged to the outer wall of the linkage rod. An inserting rod wheel is fixedly connected to the outer wall of the sliding plate. An L-shaped inclined insert is movably connected to the side of the inserting rod wheel away from the sliding plate.

[0011] Further, the inner wall of the reset spring is sleeved on the vertical rod. The vertical rod penetrates through the square plate. There are four pressing pads, which are symmetrically arranged about the center of the square plate. The bottom height of the pressing pad is lower than the bottom height of the tool. The tool and the placing plate are located on the same vertical line.

[0012] Further, the contact switch and the extrusion plate are located on the same vertical line. A through hole is formed at the connection between the square plate and the vertical rod.

[0013] Further, the ratio of the diameter length of the rotating wheel to the diameter length of the gear is 1:5. Both the left and right sides of the rotating shaft are rotatably connected to the stamping frame. There are two turntables, which are symmetrically arranged about the center of the rotating wheel.

[0014] Further, the inner wall of the sliding plate is slidably connected to the rotating shaft. An annular groove is formed inside the L-shaped inclined insert. The inserting rod wheel is embedded inside the groove. The inserting rod wheel is composed of a roller and a connecting rod. An inclined surface is formed at the connection between the placing plate and the L-shaped inclined insert. The inclined surface angles of the placing plate and the L-shaped inclined insert are the same.

[0015] A numerical control turret punch press for punching and forming, and a using method of the turret punch press are as follows:

[0016] S1: First, the user places the plate on the top of the placing plate. The first hydraulic push rod is pushed downward by hydraulic pressure to push the square plate, and at the same time, the second hydraulic push rod is also pushed by hydraulic pressure to push the cylinder. The cylinder drives the gear to rotate by using the ring layer. The gear drives the rotating wheel to rotate by using the belt. Since the ratio of the diameter length of the rotating wheel to the diameter length of the gear is 1:5, it has the effect of amplifying the rotation speed to increase the centrifugal force.

[0017] S2: The rotating wheel drives the turntable to rotate by using the rotating shaft. The turntable makes the slider inside it perform centrifugal motion. When the stamping speed of the tool is slow, the distance moved by the slider during centrifugal motion is short. The spiral spring is used for the slider to reset.

[0018] S3: The slider drives the slide plate to move by means of a linkage rod. The rotating shaft guides the slide plate and the L-shaped inclined insert. The slide plate drives the rotating wheel to move by means of a plug rod wheel. The plug rod wheel rolls inside the L-shaped inclined insert by means of a roller, and the roller can drive the L-shaped inclined insert to move by means of a groove. The L-shaped inclined insert moves towards the placing plate, and the L-shaped inclined insert causes the placing plate to move upward. The plug rod prevents the placing plate from moving and shifting, causing the placing plate and the tool to move downward, indirectly increasing the moving speed of the tool. Therefore, the cutting force becomes larger, preventing the appearance of burrs during cutting.

[0019] S4: At the same time, the square plate drives the tool to move downward. Since the bottom height of the pressure pad is lower than the bottom height of the tool, the pressure pad contacts the plate first. As the square plate moves downward, the pressure pad moves towards the square plate under the action of the plate.

[0020] S5: The pressure pad compresses the return spring and drives the vertical rod to move. The vertical rod drives the extrusion plate to move upward. At this time, the tool moves downward with the square plate for stamping. Since the placing plate moves upward, the original distance from the placing plate to the stamping changes. To avoid over-stamping, when the extrusion plate contacts the contact switch, it means that the stamping depth of the tool is sufficient, preventing the product from being unusable due to over-stamping.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. For the numerical control turret punch press for punching and forming and its usage method, by the user placing the plate on the top of the placing plate, the first hydraulic push rod is pushed downward by hydraulic pressure to drive the cylinder. The cylinder drives the gear to rotate by means of an annular layer. The gear drives the rotating wheel to rotate by means of a belt. The rotating wheel drives the turntable to rotate by means of a rotating shaft. The slider inside the turntable performs centrifugal motion. When the stamping speed of the tool is slow, the distance moved by the slider during centrifugal motion is short. The slider drives the slide plate to move by means of a linkage rod. The rotating shaft guides the slide plate and the L-shaped inclined insert. The slide plate drives the rotating wheel to move by means of a plug rod wheel. The plug rod wheel rolls inside the L-shaped inclined insert by means of a roller, and the roller can drive the L-shaped inclined insert to move by means of a groove. The L-shaped inclined insert moves towards the placing plate, and the L-shaped inclined insert causes the placing plate to move upward. The plug rod prevents the placing plate from moving and shifting, causing the placing plate and the tool to move downward, indirectly increasing the moving speed of the tool, thereby achieving the effect of maintaining the relative moving speed and preventing burrs from appearing during cutting.

[0023] 2. The CNC turret punch press for punching forming and its usage method drive the tool to move downward through a square plate. Since the bottom height of the pressure pad is lower than that of the tool, the pressure pad contacts the sheet material first. As the square plate moves downward, the pressure pad moves toward the square plate under the action of the sheet material, compresses the return spring and drives the vertical rod to move, and the vertical rod drives the extrusion plate to move upward. At this time, the tool follows the square plate to move downward for stamping. Since the placement plate moves upward, the original distance from the placement plate to the stamping position changes. To avoid over-stamping, when the extrusion plate contacts the contact switch, it means that the stamping depth of the tool is sufficient, thus achieving the effect of judging the stamping depth and avoiding over-stamping.

[0033] The vertical rod 405 penetrates through the square plate 401. There are four pressure pads 404, and they are centrosymmetric about the center of the square plate 401. The bottom height of the pressure pad 404 is lower than the bottom height of the cutter 402. The top of the vertical rod 405 is fixedly connected to a squeezing plate 406. A contact switch 407 is fixedly connected to the outer wall of the square plate 401. A transmission component 5 is fixedly connected to the inner wall of the top of the punching frame 2. The transmission component 5 includes a cylinder 501. A second hydraulic push rod 502 is fixedly connected to the top of the cylinder 501.

An adjusting component 6 is movably connected to the outer wall of the transmission component 5.

[0034] The adjusting component 6 includes a runner 601. A rotating shaft 602 is fixedly connected to both the left and right sides of the runner 601. The ratio of the diameter length of the runner 601 to the diameter length of the gear 504 is 1:5. Both the left and right sides of the rotating shaft 602 are rotatably connected to the punching frame 2. A turntable 603 is fixedly connected to the outer wall of the rotating shaft 602. A chute 604 is opened inside the turntable 603. A slider 606 is slidably connected to the inner wall of the chute 604. A spiral spring 605 is fixedly connected to the outer wall of the slider 606. A linkage rod 607 is hinged to the outer wall of the slider 606. A sliding plate 608 is hinged to the outer wall of the linkage rod 607. An inserting wheel 609 is fixedly connected to the outer wall of the sliding plate 608. An L-shaped inclined insert 610 is movably connected to the side of the inserting wheel 609 away from the sliding plate 608.

[0035] The inner wall of the sliding plate 608 is slidably connected to the rotating shaft 602. An annular groove is opened inside the L-shaped inclined insert 610. The inserting wheel 609 is embedded inside the groove. The inserting wheel 609 is composed of a roller and a connecting rod. A placing plate 7 is movably connected to the outer wall of the adjusting component 6. The cutter 402 and the placing plate 7 are located on the same vertical line. A plug rod 8 is fixedly connected to the bottom of the placing plate 7.

[0036] For a numerically controlled turret punch press for punching and forming, the usage method of the turret punch press is as follows:

[0037] S1: First, the user places the sheet on the top of the placement plate 7. The first hydraulic push rod 3 is pushed downward by hydraulic pressure to push the square plate 401, and at the same time, the second hydraulic push rod 502 also receives hydraulic pressure to push the cylinder 501. At this time, due to the cylinder 501, the cylinder 501 drives the gear 504 to rotate by using the ring layer 503, and the gear 504 drives the runner 601 to rotate by using the belt 505. Since the ratio of the diameter length of the runner 601 to the diameter length of the gear 504 is one to five, it has the effect of amplifying the rotation speed to increase the centrifugal force.

[0038] S2: The runner 601 drives the turntable 603 to rotate by using the rotating shaft 602, and the turntable 603 makes the slider 606 inside it perform centrifugal motion. When the stamping speed of the cutter 402 is slow, the distance that the slider 606 moves during centrifugal motion is short, and the spiral spring 605 is used for the slider 606 to reset.

[0039] S3: The slider 606 drives the slide plate 608 to move by using the linkage rod 607. The rotating shaft 602 has a guiding effect on the slide plate 608 and the L-shaped inclined insert 610. The slide plate 608 drives the runner 601 to move by using the inserting rod wheel 609. The inserting rod wheel 609 rolls inside the L-shaped inclined insert 610 by using the roller, and the roller can drive the L-shaped inclined insert 610 to move by using the groove. The L-shaped inclined insert 610 moves toward the placement plate 7, and the L-shaped inclined insert 610 makes the placement plate 7 move upward. The inserting rod 8 prevents the placement plate 7 from moving and offsetting, so that the placement plate 7 and the cutter 402 move downward, that is, indirectly increasing the moving speed of the cutter 402, so the cutting force becomes larger, preventing the effect of burrs appearing during cutting.

[0040] S4: At the same time, the square plate 401 drives the cutter 402 to move downward. Since the bottom height of the pressure pad 404 is lower than the bottom height of the cutter 402, the pressure pad 404 contacts the sheet first. As the square plate 401 moves downward, the pressure pad 404 moves toward the square plate 401 under the action of the sheet.

[0041] S5: The pressure pad 404 compresses the return spring 403 and drives the vertical rod 405 to move. The vertical rod 405 drives the extrusion plate 406 to move upward. At this time, the cutter 402 moves downward following the square plate 401 for stamping. Since the placement plate 7 moves upward, the original distance from the placement plate 7 to the stamping changes. To avoid over-stamping, when the extrusion plate 406 contacts the contact switch 407, it means that the stamping depth of the cutter 402 is sufficient, avoiding the effect that the product cannot be used due to over-stamping.

3. The numerically controlled turret punch press for punching and forming according to claim 1, wherein: The usage method of the turret punch press is as follows: S1: First, the user places the plate on the top of the placing plate (7). The first hydraulic push rod (3) is pushed downward by hydraulic pressure to push the square plate (401). At the same time, the second hydraulic push rod (502) is also pushed by hydraulic pressure to push the cylinder (501). The cylinder (501) drives the gear (504) to rotate by using the ring layer (503). The gear (504) drives the runner (601) to rotate by using the belt (505). Since the ratio of the diameter length of the runner (601) to the diameter length of the gear (504) is 1:5, it has the effect of amplifying the rotation speed to increase the centrifugal force. S2: The runner (601) drives the turntable (603) to rotate by using the rotating shaft (602). The turntable (603) enables the slider (606) inside it to perform centrifugal motion. When the stamping speed of the cutter (402) is slow, the distance moved by the slider (606) during centrifugal motion is short. The spiral spring (605) is used for the slider (606) to reset. S3: The slider (606) drives the sliding plate (608) to move by using the linkage rod (607). The rotating shaft (602) guides the sliding plate (608) and the L-shaped insert (610). The sliding plate (608) drives the runner (601) to move by using the inserting rod wheel (609). The inserting rod wheel (609) rolls inside the L-shaped insert (610) by using the roller, and the roller can drive the L-shaped insert (610) to move by using the groove. The L-shaped insert (610) moves towards the placing plate (7). The L-shaped insert (610) makes the placing plate (7) move upward. The inserting rod (8) prevents the placing plate (7) from moving and offsetting, so that the placing plate (7) and the cutter (402) move downward, that is, indirectly increasing the moving speed of the cutter (402), so the cutting force becomes larger, preventing the effect of burrs from appearing during cutting. S4: At the same time, the square plate (401) drives the cutter (402) to move downward. Since the bottom height of the pressure pad (404) is lower than the bottom height of the cutter (402), the pressure pad (404) contacts the plate first. As the square plate (401) moves downward, the pressure pad (404) moves towards the square plate (401) under the action of the plate. S5: The pressing pad (404) compresses the return spring (403) and drives the vertical rod (405) to move. The vertical rod (405) drives the extrusion plate (406) to move upward. At this time, the cutter (402) moves downward following the square plate (401) for stamping. Since the placement plate (7) moves upward, the original distance from the placement plate (7) to the stamping position changes. To avoid over-stamping, when the extrusion plate (406) contacts the contact switch (407), it means that the stamping depth of the cutter (402) is sufficient, thus avoiding the situation where the product becomes unusable due to over-stamping.
