Description

Technical Field

[0001] This utility model relates to the field of punching technology for parts, specifically a quick positioning device for punching. Background Technology

[0002] Punching refers to the process of placing a pre-cut sheet metal above a lower die, then driving an upper die downwards. The upper and lower dies apply pressure to punch the sheet metal into the desired shape. To ensure consistent edge dimensions of the resulting parts, the sheet metal's position is controlled. Furthermore, to prevent sheet metal displacement that could lead to uneven edge dimensions and affect the overall aesthetics of the part, [further details are needed]. Previously, cylinders were generally used for fixing, but the fixing force of cylinders is relatively large, so it may damage the sheet metal when it is thin. Although cylinders can fix sheet metal of different sizes, before punching parts, the sheet metal is first pressurized and molded to form a preliminary machined part. The preliminary machined part is then punched to a standard size. Although cylinders can fix parts of different sizes, they do not have a significant advantage in this step, and the large force of cylinders can easily damage the sheet metal during the positioning process.

[0003] Therefore, we propose a rapid positioning device for punching. Utility Model Content

[0004] The purpose of this invention is to provide a quick positioning device for punching, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick positioning device for punching, comprising: a mold plate, wherein two sets of mounting plates are installed on both sides of the mold plate; A flip-up positioning plate is rotatably connected inside the mounting plate, and a torsion spring is installed inside the flip-up positioning plate. A ratchet is installed on the outer surface of the mounting plate. The ratchet passes through the mounting plate and its end face is fixedly connected to the flip positioning plate. A first locking block and a second locking block are respectively installed on both sides of the ratchet.

[0007] Preferably, a positioning block is installed between the first and second locking blocks, the positioning block being rotatably connected to the outer surface of the mounting plate, and the positioning block being used to adjust the position of the first or second locking block.

[0008] Preferably, both the first and second locking blocks are rotatably connected to the mounting plate, and the first and second locking blocks are surrounded by a mounting frame. The mounting frame is fixedly connected to the outer surface of the mounting plate, and a first spring is fixedly connected to the outer surface of both the first and second locking blocks. Two sets of the first springs are fixedly connected to the inner wall of the mounting frame.

[0009] Preferably, a gear is fixedly connected to the side of the positioning block away from the mounting plate, and a toothed plate is meshed with the side of the gear near the mold plate.

[0014] This utility model provides a quick positioning device for punching, which has the following advantages: This invention alters the positions of the first and second locking blocks, changing the rotation direction of the ratchet and further altering the rotation direction of the flip positioning plate. When the first locking block engages with the ratchet, the flip positioning plate can only rotate clockwise, thus positioning the sheet material inside the flip positioning plate. The flip positioning plate applies less force to the sheet material, reducing the probability of damage during positioning and resulting in smaller edge dimensional errors in the parts after punching. Simultaneously, the flip positioning plate assists in separating the sheet material from the mold plate, making it easier for the user to handle the processed sheet material.

[0015] This invention adjusts the position of the positioning plate by adjusting the position of the foot pedal, thereby adjusting the positions of the first and second locking blocks, making the adjustment of the positioning plate position more convenient. Simultaneously, a second spring is installed inside the moving rod, allowing it to automatically rebound and adjust the positions of the first and second locking blocks, thus restoring the rotation direction of the flipped positioning plate. This ensures that the flipped positioning plate can automatically return to its original position after the part is processed. Attached Figure Description

The mounting plates 2 are installed on both sides of the mold plate 1, and the bottom of the mounting plates 2 is fixed to the outer surface of the punching device by bolts or the like.

[0020] A flip-up positioning plate 201 is rotatably connected inside the mounting plate 2. The flip-up positioning plate 201 is an L-shaped right-angle plate. A torsion spring 202 is installed inside the flip-up positioning plate 201. The torsion spring 202 is in a state of equilibrium when there is no external force. Figure 1 The state shown.

[0021] Ratchet 203 is installed on the outer surface of mounting plate 2. Ratchet 203 has a locking function. The ratchet 203 passes through mounting plate 2 and its end face is fixedly connected to flip positioning plate 201. Rotation of flip positioning plate 201 can drive ratchet 203 to rotate.

[0022] The first locking block 204 is installed on one side of the ratchet 203, and the first locking block 204 is movably engaged with the ratchet 203.

The positioning block 207 is rotatably connected to the outer surface of the mounting plate 2. The positioning block 207 is used to adjust the position of the first locking block 204 or the second locking block 205.

When the positioning block 207 abuts against the second locking block 205, it can separate the second locking block 205 from the ratchet 203.

[0024] The first locking block 204 and the second locking block 205 are both rotatably connected to the mounting plate 2, and the first locking block 204 and the second locking block 205 are surrounded by a mounting frame 208.

The two sets of first springs 206 are fixedly connected to the inner wall of the mounting frame 208.

[0025] A gear 3 is fixedly connected to the side of the positioning block 207 away from the mounting plate 2. The gear 3 is fixed to the positioning block 207. Adjusting the gear 3 can adjust the position of the positioning block 207. A toothed plate 301 meshes with the side of the gear 3 closest to the mold plate 1. Moving the toothed plate 301 can adjust the position of the gear 3, thereby changing the position of the positioning block 207 with rotation. The toothed plate 301 is slidably connected inside the mounting frame 208. The bottoms of the two sets of toothed plates 301 penetrate the mounting frame 208 and the end faces are fixedly connected to a crossbar 302.

[0026] A movable rod 303 is fixedly connected to the bottom of the crossbar 302. A second spring 307 is fixedly connected to the inner wall of the movable rod 303. The second spring 307 can rebound and drive the movable rod 303 to rebound, thereby changing the position of the positioning block 207, so as to achieve the purpose of adjusting the rotation direction of the flip positioning plate 201. A sliding rod 308 is fixedly connected to the bottom of the second spring 307. The sliding rod 308 is slidably connected inside the movable rod 303.

[0027] A foot pedal 304 is fixedly connected to the outer surface of the end of the moving rod 303 away from the mold plate 1.

[0028] A corresponding positioning frame 305 is provided below the mounting plate 2. A connecting plate 306 is slidably connected inside the positioning frame 305. The connecting plate 306 and the positioning frame 305 are used to stabilize the position of the moving rod 303.

[0029] The two ends of the torsion spring 202 are fixedly connected to the outer surfaces of the flip positioning plate 201 and the mounting plate 2, respectively. The torsion spring 202 can maintain the flip positioning plate 201 in a certain state. Figure 1 As shown.

[0030] This utility model provides a quick positioning device for punching, the specific working principle of which is as follows: During installation, the user first takes out two sets of mounting plates 2 and installs them on both sides of the mold plate 1. The mold plate 1 is the lower mold required for punching. Then, the user installs the positioning frame 305 on the outer surface of the punching machine and also installs the slide bar 308 on the outer surface of the punching machine. The positions of the toothed plate 301 and the cross bar 302 are adjustable. After the mounting plates 2 are installed, the distance between the two sets of toothed plates 301 is measured. According to the distance, holes are drilled on the surface of the cross bar 302, and bolts are used to fix the cross bar 302 to the toothed plate 301. When positioning the material, the flip positioning plate 201 is in the following state: Figure 1 As shown, the states of ratchet 203 and second latch 205 are as follows: Figure 4As shown in the above description, the flip positioning plate 201 can only rotate counterclockwise. Then, the user places their foot on top of the foot pedal 304 and presses down, causing the moving rod 303 to move. The moving rod 303 moves downward, causing the two sets of toothed plates 301 to move, which in turn causes the two sets of gears 3 to rotate. The gears 3 cause the positioning block 207 to rotate, causing the positioning block 207 to push the second locking block 205 to rotate, causing the second locking block 205 to separate from the ratchet 203. The first spring 206 corresponding to the second locking block 205 is compressed, while the first spring 206 originally corresponding to the first locking block 204 changes from a compressed state to an open state, causing the first locking block 204 to move and engage with the ratchet 203, thus changing the rotation direction of the flip positioning plate 201. Then, the user places the pre-processed part on top of the flip positioning plate 201 and moves their hands to both sides of the flip positioning plate 201, pushing inward to rotate the flip positioning plate 201. The state of the flip positioning plate 201 is as follows: Figure 2 As shown, since a ratchet 203 is provided on one side of the flip positioning plate 201, the flip positioning plate 201 has a locking function, which allows the flip positioning plate 201 to hold the plate. Then, the punching machine is started to drive the upper die to press down, so that the upper die and the mold plate 1, i.e., the lower die, are in contact, thereby achieving the purpose of punching the plate. During the punching process, the foot pedal 304 is released, and the foot pedal 304 drives the positioning block 207 to rotate, so that the second locking block 205 engages with the ratchet 203. However, since the upper part of the flip positioning plate 201 is pressed down by the upper die, the flip positioning plate 201 will not change. When the punching is finished, when the upper die moves upward, the elastic resistance torque of the torsion spring 202 will drive the flip positioning plate 201 to rotate, thereby causing the flip positioning plate 201 to move the plate upward, so that the plate is separated from the mold plate 1, making it more convenient for the user to take the processed plate.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
