Description

Technical Field

[0001] This utility model relates to the field of punch press technology, and in particular to a fixed clamping mechanism for punch press processing. Background Technology

[0002] A punch press is a stamping press. In national production, stamping technology has advantages over traditional machining, such as saving materials and energy, high efficiency, low operator skill requirements, and the ability to produce products that cannot be achieved by machining through the application of various molds.

[0003] In the prior art, such as the Chinese patent publication number CN211105833U, a punch press with a guiding and error-correcting effect is disclosed. This includes a punch press base, a stamping die on the top of the base, the stamping die being fixedly connected to the base, an L-shaped support column on the top of the base and one side of the die, the bottom of the vertical rod of the L-shaped support column being fixedly connected to the base, and a punch cutter on the bottom of the horizontal rod of the L-shaped support column and directly above the die. The beneficial effects achieved by this invention are: this punch press has a guiding and error-correcting effect. By setting a fixed guiding mechanism below the punch cutter head, the punch cutter head can be corrected. The internal structure of the guiding mechanism is double-layered, first limiting the lateral displacement of the punch cutter head, and then limiting the longitudinal displacement, thus preventing displacement of the cutter head during descent. The guiding mechanism is fixedly connected and its position is relatively fixed to the bottom stamping template, preventing punching offset.

[0004] When stamping parts are stamped by a punch press, a clamping mechanism is first needed to clamp the stamping parts. The existing clamping mechanism has a fixed clamping position and clamping angle when clamping the stamping parts. Since the shapes of stamping parts are different, different stamping parts need to be clamped by different clamping mechanisms, which is not only cumbersome to disassemble and assemble, but also increases costs. Therefore, the above problems need to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a fixed clamping mechanism for punching processing, which has the effect of clamping different stamped parts.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fixed clamping mechanism for punching machine processing, including a worktable and a mounting plate. The worktable has a placement plate inside, and the placement plate has a placement groove inside. Electric slide rails are fixedly installed on the inner edges of the placement plate. A moving block is provided at the output end of the electric slide rail. A column is fixedly connected to the top of the moving block. A motor is fixedly installed inside the column. A gearbox is fixedly connected to the top of the motor. A first gear and a second gear are rotatably connected inside the gearbox. The first gear and the second gear mesh with each other. The first gear is fixedly connected to the output end of the motor. A connecting plate is fixedly connected to the center of the second gear. A screw is threadedly connected inside the connecting plate. A bearing housing is fixedly installed at the bottom of the screw. A bearing is fixedly installed inside the bearing housing. A pressure plate is rotatably connected inside the bearing.

[0007] By adopting the above technical solution, when stamping the stamped part, the stamped part is installed into the placement groove inside the placement plate. According to the shape and placement position of the stamped part, the electric slide rail is activated, so that the electric slide rail drives the columns to move through the moving block. There are three columns. The movement of the three columns allows the three columns to travel outside the stamped part. Then, the motor is started, so that the motor drives the first gear to rotate. The first gear meshes with the second gear, which in turn drives the connecting plate to rotate, flipping one end of the connecting plate above the stamped part. Then, the screw is twisted, so that the screw extends and retracts inside the connecting plate. The connecting plate drives the bearing housing, bearing and pressure plate to move down. The pressure plate contacts the stamped part, thus clamping the stamped part. The three pressure plates fix the outer edge of the stamped part, which not only improves the clamping effect, but also allows the position of the three pressure plates to be adjusted according to the position and shape of the stamped part, so that this device can clamp and fix different stamped parts.

[0008] A further feature of this invention is that a rubber pad is fixedly connected to the bottom of the pressure plate, and an anti-slip strip is fixedly connected to the bottom of the rubber pad.

[0009] By adopting the above technical solutions, the rubber mat material is soft, and the anti-slip strips improve friction.

[0010] A further feature of this invention is that a handle is fixedly connected to the top of the screw, and a protective sleeve is fixedly connected to the outside of the handle.

[0011] By adopting the above technical solution, it is relatively convenient to turn the screw by holding the handle.

[0012] A further feature of this invention is that the number of pressure plates is three.

[0013] By adopting the above technical solution and setting up three pressure plates, the clamping effect can be improved.

[0014] A further feature of this invention is that an electric push rod is fixedly installed at the center of the mounting plate, and a locking block is fixedly connected to the outer side of the workbench, the locking block being fixedly connected to the output end of the electric push rod.

[0015] By adopting the above technical solution, the mounting plate is fixed inside the punch press, and the worktable is fixed to the output end of the electric push rod by the clamping block. The electric push rod is started, which drives the worktable to move. After the stamping of the part is completed, the electric push rod pushes the worktable out, and the stamping part can be taken out. This process is highly safe.

[0016] A further feature of this invention is that the internal thread of the card block is connected to a screw shaft, and the external thread of the screw shaft is connected to a nut.

[0017] By adopting the above technical solution, the screw shaft passes through the interior of the locking block and the output end of the electric push rod, and the nut is locked at both ends of the screw shaft, thereby fixing the locking block to the output end of the electric push rod.

[0018] A further feature of this invention is that both sides of the mounting plate are fixedly connected to rails, and the bottom of the workbench is provided with pulleys.

[0019] By adopting the above technical solution, the pulleys will travel inside the track during the movement of the work platform, improving the support for movement.

[0020] A further feature of this invention is that the number of pulleys is four, and the four pulleys are distributed in a rectangular array at the bottom of the workbench.

[0021] By adopting the above technical solution, there are two tracks, and four pulleys are distributed at the four corners of the bottom of the workbench, with the four pulleys evenly distributed inside the two tracks.

[0022] A further feature of this invention is that the top of both the workbench and the placement plate are overlapped by Z-plates, and the Z-plates are internally threaded with screws.

[0023] By adopting the above technical solution, the Z-plate is overlapped on top of the workbench and the placement plate, and the placement plate is fixed above the workbench by screws.

[0024] A further feature of this invention is that the number of Z-plates is three, and the three Z-plates are distributed in a ring array.

[0025] By adopting the above technical solution and setting up three Z-plates, the stability of the placement plate after installation can be improved.

[0026] The beneficial effects of this utility model are:

[0027] 1. This utility model, through the arrangement of a workbench, a placement plate, a placement groove, an electric slide rail, a moving block, columns, a motor, a gearbox, a first gear, a second gear, a connecting plate, a screw, a bearing housing, a pressure plate, and a bearing, allows the stamping of a part to proceed. The stamping part is installed into the placement groove inside the placement plate. The electric slide rail is activated according to the shape and placement position of the stamping part, causing the moving block to drive the columns to move. There are three columns, allowing them to travel outside the stamping part. Then, the motor is activated, driving the first gear... The wheel rotates, and the first gear meshes with the second gear, causing the second gear to drive the connecting plate to rotate. This flips one end of the connecting plate above the stamping part. Then, the screw is twisted, causing it to extend and retract inside the connecting plate. The connecting plate drives the bearing housing, bearing, and pressure plate to move downwards. The pressure plate contacts the stamping part, thus clamping it. The three pressure plates fix the outer edge of the stamping part, which not only improves the clamping effect but also allows the position of the three pressure plates to be adjusted according to the position and shape of the stamping part. This enables the device to clamp and fix different stamping parts.

This utility model, through the arrangement of a mounting plate, an electric push rod, a locking block, a screw shaft, a nut, a track, and pulleys, fixes the mounting plate inside the punch press. The worktable is fixed to the output end of the electric push rod by the locking block. Activating the electric push rod causes it to move the worktable. After the stamping of the part is completed, the electric push rod pushes the worktable out, allowing the stamped part to be removed. This process is highly safe. The screw shaft passes through the inside of the locking block and the output end of the electric push rod, and the nut is locked at both ends of the screw shaft. The locking block is fixed to the output end of the electric push rod by the nut. During the movement of the worktable, the pulleys will move inside the track, improving the support for movement.

According to the shape and placement position of the stamping part, the electric slide rail 4 is activated, so that the electric slide rail 4 drives the column 6 to move through the moving block 5. There are three columns 6. The movement of the three columns 6 allows the three columns 6 to move outside the stamping part. Then, the motor 7 is activated, so that the motor 7 drives the first gear 9 to rotate. The first gear 9 meshes with the second gear 10, which in turn drives the connecting plate 11 to rotate, flipping one end of the connecting plate 11 to the top of the stamping part. Then, the screw is turned. 12. This causes the screw 12 to extend and retract within the connecting plate 11. The connecting plate 11 drives the bearing housing 13, bearing, and pressure plate 14 to move downwards. The pressure plate 14 contacts the stamping part, thus clamping the stamping part. The three pressure plates 14 fix the outer edge of the stamping part, which not only improves the clamping effect but also allows the position of the three pressure plates 14 to be adjusted according to the position and shape of the stamping part. This allows the device to clamp and fix different stamping parts. A rubber pad 15 is fixedly connected to the bottom of the pressure plate 14, and an anti-slip strip 16 is fixedly connected to the bottom of the rubber pad 15. The rubber pad 15 is made of soft material, and the anti-slip strip 16 increases the friction.

This process is highly safe. The internal thread of the locking block 20 is connected to a screw shaft 21, and the external thread of the screw shaft 21 is connected to a nut 22.The screw shaft 21 extends through the interior of the locking block 20 and the output end of the electric push rod 19.

Tracks 23 are fixedly connected to both sides of the mounting plate 18. Pulleys 24 are installed at the bottom of the worktable 1. During movement, the pulleys 24 will travel within the tracks 23, improving movement support. There are four pulleys 24 arranged in a rectangular array at the bottom of the worktable 1. The number of tracks 23... There are two pulleys, four in total, distributed at the four corners of the bottom of the workbench 1. The four pulleys 24 are evenly distributed inside the two tracks 23.

There are three columns 6, which can move outside the stamping part. Then, the motor 7 is activated, driving the first gear 9 to rotate. The first gear 9 meshes with the second gear 10, causing the second gear 10 to rotate the connecting plate 11, flipping one end of the connecting plate 11 above the stamping part. Then, the screw 12 is twisted, causing it to extend and retract inside the connecting plate 11. The connecting plate 11 causes the bearing housing 13, bearing, and pressure plate 14 to move downwards. The pressure plate 14 contacts the stamping part, thus clamping it. The three pressure plates 14... Fixing the outer edge of the stamped part not only improves the clamping effect, but also allows the position of the three pressure plates 14 to be adjusted according to the position and shape of the stamped part, enabling the device to clamp and fix different stamped parts. The mounting plate 18 is fixed inside the punch press, and the worktable 1 is fixed to the output end of the electric push rod 19 by the locking block 20. The electric push rod 19 is started, causing the electric push rod 19 to drive the worktable 1 to move.
