Description

Technical Field

[0001] The present invention relates to the technical field of stamping dies, and more particularly, to a stamping die for aluminum alloy sheets. Background Art

[0002] A stamping die for aluminum alloy sheets is a special tool for processing aluminum alloy sheets, which processes the aluminum alloy sheets into the required shapes or parts through cold stamping technology.

[0003] The existing stamping dies for aluminum alloy sheets usually consist of a female die and a male die. A press is used to apply pressure to the die, causing plastic deformation or separation of the aluminum alloy sheet inside the die. During the stamping process of the aluminum alloy sheet, the operator needs to hold the aluminum alloy raw material by hand and place it into the guide post of the die. Subsequently, the press and the die cooperate to stamp the aluminum alloy raw material. After stamping, the operator also needs to reach into the die and take out the aluminum alloy stamping finished product from the guide post. There are significant safety hazards during the process of taking and placing, and the accuracy during manual placement is relatively low. After the operator holds the aluminum alloy raw material close to the guide post, further manual alignment is required before clamping it into the guide post. During this process, the operator's arm stays between the dies for operation, increasing the risk of safety accidents.

[0004] To solve the above problems, the inventor has proposed a stamping die for aluminum alloy sheets. Summary of the Invention

A bidirectional lead screw is rotatably connected inside the fixing frame. Both ends of the bidirectional lead screw are threadedly connected to a sliding plate. Two limiting shafts are symmetrically slidably connected to each of the two sliding plates. One end of each two limiting shafts close to the bidirectional lead screw is commonly and fixedly connected to a clamping plate. A first spring is arranged between the sliding plate and the clamping plate. Two clamping pieces are symmetrically and fixedly connected to each of the two clamping plates. Triangular blocks are fixedly connected to the middle of the two clamping plates. A first pressing switch is fixedly installed in the middle of each of the two clamping plates. A baffle is fixedly connected to the side of each of the two clamping pieces close to the lower die.

[0007] Preferably, the bottom surfaces of the two sliding plates are attached to the inner top of the fixing frame.

[0008] Preferably, a first motor is fixedly installed on the side surface of the second rotating seat. The output shaft of the first motor passes through the first rotating seat and is fixedly connected to the second rotating seat close thereto.

[0009] Preferably, a second motor is fixedly installed on the side of the fixing frame close to the first motor. The output shaft of the second motor passes through the fixing frame and is fixedly connected to the bidirectional lead screw.

[0010] Preferably, the triangular block is a right triangle, and the inclined surface of the triangular block faces the side of the clamping plate away from the sliding plate.

[0011] Preferably, an adaptation assembly is provided on the top of the lower mold. The adaptation assembly includes a nut seat fixedly connected to the middle of the side of the fixing frame away from the lower mold. A bolt is threadedly connected in the nut seat. The top of the bolt is rotatably connected to a top plate. Two sliding rods are symmetrically and fixedly connected to the top plate. Two sliding sleeves are symmetrically and fixedly connected to the side of the fixing frame away from the lower mold. The two sliding rods are respectively slidably connected to the two sliding sleeves. An electric telescopic rod is fixedly installed on the side of the lower mold close to the first rotating seat. The movable end of the electric telescopic rod is fixedly connected to a moving plate. A rack is fixedly connected to the top of the moving plate close to the side of the electric telescopic rod. A rotating rod is provided on the side of the rack away from the moving plate. The end of the rotating rod away from the rack is fixedly connected to a contact seat. A second pressing switch is fixedly installed on the side of the contact seat away from the rotating rod.

[0012] Preferably, a fixing seat is fixedly installed on the side of the lower mold close to the nut seat. A gear is rotatably connected to the top of the fixing seat. The gear is meshed with the rack. A rotating cylinder is fixedly connected to the top of the gear. A sliding shaft is slidably connected in the rotating cylinder.

[0013] Preferably, two sliding grooves are symmetrically formed in the rotating cylinder. Two sliding blocks are symmetrically and fixedly connected to the sliding shaft. The two sliding blocks are respectively slidably connected to the two sliding grooves. A second spring is arranged in the rotating cylinder.

[0016] As described above, the characteristics and advantages of an aluminum alloy sheet stamping die in the present invention are: Through the cooperation of the triangular block and the guide pillar, after the aluminum alloy raw material in the clamped state approaches the die stamping groove, the triangular block automatically releases the aluminum alloy raw material through the guide pillar at the edge of the die stamping groove. The aluminum alloy raw material is fixed in the die stamping groove along the guide pillar, eliminating the need for the operator to hold the aluminum alloy raw material and place it inside the guide pillar, thus avoiding the safety hazard of the operator reaching their hand between the stamping dies and improving the safety of aluminum alloy sheet stamping. Through the setting of the bidirectional lead screw and the clamping plate, after the aluminum alloy raw material is placed on the top plate, the clamping plate automatically moves to clamp the aluminum alloy raw material, automatically adapting to aluminum alloy raw material plates of different sizes. Moreover, the two clamping plates move towards the middle synchronously, enabling the aluminum alloy raw material plate to be centered during the clamping process, eliminating the need to align it with the die stamping groove for placement. By driving the clamping piece to move towards the middle through the clamping plate, the clamping piece clamps the aluminum alloy stamping finished product between the aluminum alloy stamping finished product and the guide pillar. Subsequently, the top plate rotates and resets to take out the aluminum alloy stamping finished product between the stamping dies, eliminating the need for the operator to reach their hand into the stamping dies to pick it up, completely avoiding the safety hazard of the operator reaching their hand between the stamping dies in traditional aluminum alloy stamping operations. Through the cooperation of the contact seat and the bolt, after replacing different stamping dies, the top plate rises and falls in height according to the change in the position of the guide pillar, ensuring that the center of the aluminum alloy raw material always aligns with the center of the aluminum alloy die stamping groove. Consequently, the edge of the aluminum alloy raw material always aligns with the guide pillar. After release, the aluminum alloy raw material falls into the stamping die groove through the guide pillar, enabling the device to achieve the effect of adapting to aluminum alloy stamping dies of different sizes, eliminating the need for manual alignment between the dies, further enhancing the safety of aluminum alloy stamping work, and further improving the applicability of the aluminum alloy sheet stamping die.

The output shaft of the second motor 214 passes through the fixing frame 203 and is fixedly connected to the bidirectional lead screw 204.

[0021] Further, as Figure 1 , Figure 2 and Figures 6 to 10As shown in the figure, an adaptation component is provided at the top of the lower mold 1. The adaptation component includes a nut seat 301 fixedly connected to the middle of the fixing frame 203 away from one side of the lower mold 1.

Two sliding rods 304 are symmetrically and fixedly connected to the top plate 303. Two sliding sleeves 305 are symmetrically and fixedly connected to the side of the fixing frame 203 away from the lower mold 1. The two sliding rods 304 are respectively slidably connected to the two sliding sleeves 305. The cooperation between the sliding rod 304 and the sliding sleeve 305 enables the top plate 303 to only vertically lift on the fixing frame 203. An electric telescopic rod 306 is fixedly installed on the side of the lower mold 1 close to the rotating seat one 201. The movable end of the electric telescopic rod 306 is fixedly connected to a moving plate 307. A rack 308 is fixedly connected to the top of the moving plate 307 close to one side of the electric telescopic rod 306.

A spring two 318 is arranged inside the rotating cylinder 314. The two ends of the spring two 318 are fixedly connected to the inner bottom of the rotating cylinder 314 and the sliding shaft 315. Strong magnets 319 are provided at the top end of the sliding shaft 315 and the bottom end of the bolt 302. The two strong magnets 319 form a magnetic attraction cooperation. The strong magnets 319 are eccentrically arranged inside the bolt 302 and the sliding shaft 315. When the two strong magnets 319 attract each other, the sliding shaft 315 can drive the bolt 302 to rotate. A rotating groove 320 is opened on the side of the rack 308 close to the rotating rod 309. The rotating rod 309 is rotatably connected inside the rotating groove 320. A motor three 321 is fixedly installed at the bottom on the side of the rack 308 close to the rotating groove 320. The output shaft of the motor three 321 passes through the rack 308 and is fixedly connected to the rotating rod 309.

[0022] Combined with the above embodiments, the following is the entire working process and working principle of the above embodiments: The initial state is: The fixing bracket 203 is not powered on, the second rotating seat 202 does not rotate, the second rotating seat 202 and the fixing bracket 203 are in a vertically upward state, the second motor 214 is not powered on, the two sliding plates 205 are respectively located at both ends of the bidirectional lead screw 204, the first spring 208 is not compressed, the first pressing switch 211 is not pressed, the telescopic end of the electric telescopic rod 306 extends, the third motor 321 is not powered on, the direction of the rotating rod 309 is the same as that of the rack 308, the second spring 318 is in a compressed state, and the two strong magnets 319 are in a magnetically attracted state.

[0023] The working state is: Placing raw materials: When performing a stamping operation, place the plate-shaped aluminum alloy raw material between the two clamping plates 207 and on the upper surface of the top plate 303. Subsequently, the second motor 214 is started, and the two sliding plates 205 are driven by the bidirectional lead screw 204 to move towards the middle of the bidirectional lead screw 204. The two clamping plates 207 come into contact with the plate-shaped aluminum alloy raw material, and under the elastic force of the first spring 208, the clamping plates 207 are kept in contact with the side surface of the aluminum alloy raw material, thereby fixing the aluminum alloy raw material, and the effect of fixing aluminum alloy raw materials of different sizes can be achieved.

[0024] Putting in raw materials: After the aluminum alloy raw material is fixed between the two clamping plates 207 and the top plate 303, the first motor 213 is started to drive one of the second rotating seats 202 to rotate, so that the second rotating seat 202 drives the fixing bracket 203 to rotate, thereby the sliding plates 205, the clamping plates 207 and the top plate 303 rotate synchronously towards the middle of the lower die 1. During this process, the two protruding baffles 212 block the aluminum alloy raw material so that it will not slide out between the two clamping plates 207. When the aluminum alloy raw material approaches the die groove, the triangular block 210 contacts the guide post. Under the action of the inclined surface of the triangular block 210 being squeezed, the clamping plates 207 move towards the sliding plates 205 and compress the first spring 208. After the two clamping plates 207 slide, the baffle 212 no longer blocks the aluminum alloy raw material, so that the aluminum alloy raw material falls along the guide post above the die groove, achieving the effect of accurately and automatically putting in the aluminum alloy raw material.

[0025] It should be noted that: after the top plate 303 rotates following the fixing bracket 203, the edge of the top plate 303 is at the same horizontal plane as the edge of the die groove. Therefore, it can be ensured that the aluminum alloy raw material falls along the guide post above the die groove.

[0026] Automatic connection: When the motor 1 (213) drives the rotating seat 2 to rotate, causing the sliding plate 205, the clamping plate 207, and the top plate 303 to rotate synchronously downward towards the lower die 1, the bolt 302 rotates synchronously under the drive of the fixing frame 203. The bottom end of the bolt 302 squeezes the sliding shaft 315 during the tilting process, causing the sliding shaft 315 to slide vertically downward within the rotating cylinder 314 under the action of the sliding groove 316 and the slider 317, and compressing the second spring 318. Subsequently, after the bottom end of the bolt 302 follows the fixing frame 203 to rotate until it no longer contacts the sliding shaft 315, the sliding shaft 315 resets under the action of the second spring 318. When the motor 1 (213) drives the rotating seat 2 to reset, causing the sliding plate 205, the clamping plate 207, and the top plate 303 to reset, the bolt 302 resets under the drive of the fixing frame 203, causing the bottom edge of the bolt 302 to first contact the top end of the sliding shaft 315 in an inclined state and squeeze the sliding shaft 315, causing the sliding shaft 315 to slide downward within the rotating cylinder 314 and compress the second spring 318 until the bolt 302 rotates to a perpendicular state with the sliding shaft 315. During this process, since neither the bolt 302 nor the sliding shaft 315 rotates, the two strong magnets 319 remain aligned. After the bolt 302 leaves the sliding shaft 315 and resets to contact the sliding shaft 315 again, the sliding shaft 315 can always drive the bolt 302 to rotate through the strong magnets 319.

[0027] Removing the finished product: When the aluminum alloy raw material enters the mold groove and needs to be stamped, the motor 1 (213) starts to drive the rotating seat 2 to reset, thereby driving the sliding plate 205, the clamping plate 207, and the top plate 303 to reset. At the same time, the motor 3 (321) starts to drive the rotating rod 309 to rotate until it is perpendicular to the rack 308. Subsequently, the aluminum alloy raw material can be stamped. After stamping, the size of the aluminum alloy finished product is the same as that of the stamping groove. Therefore, there is a gap between the edge of the aluminum alloy stamped finished product and the guide post. Subsequently, the motor 1 (213) drives the sliding plate 205 and the clamping plate 207 to rotate into the gap between the edge of the aluminum alloy finished product and the guide post. Subsequently, the motor 2 (214) starts to drive the sliding plate 205 to further slide towards the middle of the bidirectional lead screw 204, causing the four clamping pieces 209 to clamp the edge of the aluminum alloy finished product. Subsequently, the motor 1 (213) drives the sliding plate 205 and the clamping plate 207 to reset again, and the aluminum alloy finished product can be taken out of the mold groove, achieving the effect of automatically taking out the aluminum alloy stamped finished product from the mold. And under the action of the bidirectional lead screw 204, it can adapt to aluminum alloy stamped finished products of different sizes.

[0028] Size adaptability: When replacing different die slot bases and guide pillars, and the two clamping plates 207 need to clamp aluminum alloy raw materials of different sizes, the third motor 321 is started to rotate the rotating rod 309 to the same direction as the rack 308. Subsequently, the electric telescopic rod 306 is started and its telescopic end is retracted, so that the moving plate 307 drives the rack 308 to move downward towards the die 1, thereby pushing the rotating rod 309 and the contact seat 310 towards the guide pillar. It moves until the second pressure switch 311 contacts and is squeezed by the centered guide pillar. When the second pressure switch 311 is squeezed into the contact seat 310 and the contact seat 310 contacts the guide pillar, the electric telescopic rod 306 is powered off. During the process of the rack 308 moving driven by the electric telescopic rod 306 and the moving plate 307, the movement of the rack 308 will drive the gear 313 to rotate through meshing connection, so that the rotating cylinder 314 drives the sliding shaft 315 to rotate through the cooperation of the chute 316 and the slider 317. Thus, driven by the cooperation of the two strong magnets 319, the bolt 302 rotates, so that the bolt 302 moves downward in cooperation with the nut seat 301, driving the top plate 303 to move downward relative to the fixed frame 203. During this process, the downward rotation of the bolt 302 will squeeze the sliding shaft 315, so that the sliding shaft 315 slides into the rotating cylinder 314 while maintaining rotation through the cooperation of the chute 316 and the slider 317, and squeezes the second spring 318. So that when the telescopic end of the electric telescopic rod 306 extends, when the rack 308 drives the bolt 302 to rotate through the gear 313, the rotating cylinder 314, the sliding shaft 315 and the strong magnet 319, the bolt 302 pushes the top plate 303 to move upward. During this process, the compressed second spring 318 continuously pushes the sliding shaft 315 to slide upward in the rotating cylinder 314, so that the top surface of the sliding shaft 315 always contacts the bottom surface of the bolt 302 during the lifting process of the bolt 302, thus maintaining the connection effect of the two strong magnets 319. According to the contact of the rack 308, the rotating rod 309 and the contact seat 310 with the guide pillars at different positions, and synchronously driving the top plate 303 to descend, when the edge of the aluminum alloy raw material contacts the top plate 303, after the clamping plate 207 and the top plate 303 rotate above the die slot, the edges of aluminum alloy raw materials of different sizes can be aligned with the guide pillars and smoothly slide into the die slot under the action of the guide pillars, realizing the effect of adapting to the placement of aluminum alloy raw materials of different sizes.

[0029] The above are only embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
