[0027] Embodiment 1

[0028] As Figures 2-6 shown, a multi-point positioning punching die is used for positioning and punching a metal plate. It includes a base 1, a placement plate 3, a limiting plate 31, a waste slot 32, a receiving portion 34, a mounting portion 13, and a conveying portion 2. A placement plate 3 for placing the metal plate is provided on the base 1. The interior of the placement plate 3 is an empty slot, and the placement plate 3 is in the shape of a "return" character in a top view. A limiting plate 31 for limiting the metal plate is detachably provided on one side of the top of the placement plate 3. Locking screw grooves are provided inside both the limiting plate 31 and the placement plate 3. During use, the limiting plate 31 is fixed to the placement plate 3 through bolts and the locking screw grooves. As Figure 2 shown, there is a certain gap between the placement plate 3 and the limiting plate 31 at this time. This gap is used to pass the metal plate to avoid the phenomenon of the metal plate shifting during stamping.

[0029] The waste slot 32 is provided inside the placement plate 3. A part of the receiving portion 34 is inserted into the waste slot 32, and the waste slot 32 is used to clean the sheet metal waste that enters the placement plate 3.

[0030] The receiving part 34 includes a receiving plate 341 inserted into the waste groove 32 transversely relative to the storage plate 3, wherein the plane where the lowest point of the receiving plate 341 is located is higher than the plane where the lowest point of the storage plate 3 is located, the receiving plate 341 is designed as an inclined plate, the bottom of the receiving plate 341 designed as an inclined plate is designed as a plane in order to avoid that the sheet metal waste is retained in the interior of the waste groove 32, four sliding rods 344 slidingly inserted into the waste groove 32 are welded on both sides of the receiving plate 341, the ends of two sliding rods 344 away from the receiving plate 341 are fixed with vertical rods 347 designed as an "L" shape, the sliding rods 344 are used to limit the up-and-down displacement track of the receiving plate 341, specifically, the vertical rods 347 close to the limiting plate 31 are symmetrically distributed on the longitudinal central axis of the limiting plate 31 relative to the storage plate 3, for example, if the plane where the lowest point of the receiving plate 341 is located is one centimeter higher than the plane where the lowest point of the storage plate 3 is located, then the vertical rods 347 are pressed one centimeter by the mounting part 13 after abutting against the mounting part 13, that is, the length of the vertical rods 347 needs to be produced according to the actual distance between the vertical rods 347 and the mounting part 13, since the positioning punching is performed by replacing the punching head to punch at different positions, the vertical rods 347 do not need to be adjusted for many times, and the vertical rods 347 do not affect the mounting and dismounting of the punching head when in use.

[0031] The vertical plate 345 made of rubber is fixed at the top of the receiving plate 341 in the waste groove 32, a plurality of air holes 346 are formed in the vertical plate 345, when the vertical rods 347 are stressed, the receiving plate 341 will be deformed under the limitation of the vertical plate 345, the air holes 346 and the soft rubber material of the vertical plate 345 itself, so that the receiving plate 341 drives the sliding rods 344 to displace up and down in the waste groove 32, when the stress of the vertical rods 347 is over, the receiving plate 341 will be pulled back to the original position under the elastic action of the rubber of the vertical plate 345, the up-and-down displacement between them will make the receiving plate 341 vibrate longitudinally, and then the sheet metal waste in the waste groove 32 is discharged, the vertical rods 347 are pressed by the storage plate 3 to drive the receiving plate 341 to be stressed longitudinally relative to the storage plate 3, so that the vertical plate 345 is deformed to drive the receiving plate 341 to shake.

[0032] The waste groove 32 comprises a first groove 321, a second groove 322 and a third groove 323. The first groove 321 is symmetrically arranged on both sides of the second groove 322 relative to the longitudinal center line of the storage plate 3.

One side of the receiving plate 341 is movably connected with the inclined surface of the first groove 321. When the sheet metal waste falls into the first groove 321, the sheet metal waste will enter the second groove 322 along the inclined surface and be discharged. The bottom of the first groove 321 and the second groove 322 is through the bottom of the storage plate 3. The second groove 322 is transversely through the two sides of the storage plate 3. The third groove 323 is transversely through the side wall of the storage plate 3. Specifically, the metal plate is positioned and punched by the limiting plate 31 from the conveying part 2 to the upper side of the waste groove 32 when the device is working. The sheet metal waste produced after punching will enter the waste groove 32. The inclined plate-shaped receiving plate 341 will discharge the sheet metal waste under the upward and downward displacement of the sliding rod 344 and the third groove 323.

[0034] The receiving part 34 further comprises a straight plate 342 welded to the side of the receiving plate 341 away from the vertical plate 345. The surface of the straight plate 342 is fixed with a plurality of rubber pads 343.

[0038] The top of the base 1 is also provided with a conveying part 2 for conveying the metal plate, the conveying part 2 is located on the top of the base 1 close to the limiting plate 31, the conveying part 2 is provided with four rotatable roller shafts, which are divided into two groups, each group has two roller shafts arranged in an upper and lower manner, the metal plate is conveyed between the two groups, during use, the metal plate passes through the roller shafts in the conveying part 2 and reaches the storage plate 3 for punching.

[0039] The effect of the whole embodiment one is that the positions of the base 51 and the storage plate 3 can be fixed through locking screw grooves and bolts, then the limiting plate 31 is fixed on the storage plate 3 through bolts and locking screw grooves, Figure 2 and Figure 3As shown, there is a certain gap between the placement plate 3 and the limiting plate 31 at this time. This gap is used to allow the metal plate to pass through and prevent the metal plate from shifting during stamping. During operation, the metal plate passes through the limiting plate 31 from the position of the conveying section 2 and reaches the top of the waste trough 32. When the device is working, it will perform positioning punching on the metal plate above the waste trough 32.

[0041] like Figures 2-6 As shown, a multi-point positioning punching die is disclosed. This multi-point positioning punching die also includes a support frame 11, a cylinder 12, and a mounting part 13. The bottom of the support frame 11 is detachably connected to the top of the base 1. The cylinder 12 is detachably mounted on the bottom of the support frame 11. The support frame 11 supports the cylinder 12 and provides support force. The support frame 11 has an inverted "L" shape design for easy observation and maintenance by the operator. The working principle of the cylinder 12 is to use compressed air to cause the piston to reciprocate linearly within the cylinder 12, thereby converting heat energy into mechanical energy. The cylinder 12 mainly consists of a cylinder body, piston, piston rod, and sealing ring. When compressed air enters the cylinder 12, the piston moves under pressure. By changing the air intake direction, the direction of piston rod movement can be changed. This is a publicly available technology and will not be described in detail below. The mounting part 13 is detachably installed at the output end at the bottom of the cylinder 12 for mounting a punching head, making the device suitable for different types of punching heads. The center point of the mounting part 13 and the center point of the shelf 3 are on the same straight line, which facilitates the positioning and punching operation of the metal plate on the top of the shelf 3.
