In fact, the cylinder of the electric telescopic rod 505 is fixedly connected to the bottom plate 501, and the movement direction of the movable end of the electric telescopic rod 505 is parallel to the guide column 502, so that the lower mold 3 can be carried. It makes lifting movement along the direction of the guide column 502. The lower surface of the base plate 501 is also fixedly connected with a support column 503, which is used to allow the base plate 501 to be suspended at a certain height from the ground. A shock-absorbing block 504 is also arranged at the bottom of the support column 503 to reduce the influence of ground vibration on the stamping accuracy; the upper surface of the lower mold 3 is also provided with a positioning groove 302 continuous with the cavity 303, the main part of the cavity 303 is located below the positioning groove 302, the positioning groove 302 runs through the front and rear sides of the lower mold 3, and the width of the positioning groove 302 in the left and right directions is equal to the width of the unpressurized metal sheet in the left and right directions, which can well limit the distance between the left and right sides of the raw material sheet 9 and the cavity 303, thereby ensuring the accuracy of the stamping position of the metal sheet, and the front side of the lower mold 3 is also fixedly connected with a discharge plate 6, the inner wall of the discharge plate 6 is lower than the inner wall of the cavity 303 in any vertical plane, and the front end of the discharge plate 6 is lower than the rear end, and the metal sheet formed after stamping slides off the discharge plate 6 under the action of its own gravity.

[0042] The bottom of the upper mold 4 is movably connected with a punch head 8, which is a component that directly contacts the metal sheet and applies extrusion force. The top of the upper mold 4 is provided with a driving mechanism 1 and a transmission mechanism 2. The driving mechanism 1 drives the punch head 8 through the transmission mechanism 2, so that the raw material sheet 9 is pressed into the cavity 303 to become a molded part. The specific structure of the transmission mechanism 2 includes a shell 210 fixedly connected to the upper mold 4, and a gear shaft 220 and two crankshafts 230 are rotatably connected in the shell 210. The two crankshafts 230 have the same structure and are always in a parallel state. The gear shaft 220 is connected to the output end of the driving mechanism 1 to drive the two crankshafts 230 to rotate synchronously. The gear shaft 220 includes a stepped shaft 221, and a driving gear 223 is provided in the middle of the stepped shaft 221. A driven gear 232 is provided in the middle of the main shaft journal 231. The two driven gears 232 have the same size, which are both smaller than the driving gear 223, and the two driven gears 232 do not mesh with each other. The two driven gears 232 only rotate simultaneously. It meshes with the driving gear 223, and the gear meshing can ensure the transmission accuracy, thereby ensuring that the two crankshafts 230 rotate synchronously. The directions of the crank arms 233 on the two crankshafts 230 are the same during assembly, and will remain the same during subsequent movement. The driving mechanism 1 includes a servo motor 101 and a reducer 102 fixedly connected to the outer side of an end cover 213. The servo motor 101 has high control accuracy, and its output end is connected to the input end of the reducer 102, and can output high torque and high precision. One end of the stepped shaft 221 passes through an end cover 213 and is connected to the output end of the reducer 102, and the other end passes through another end cover 213 and is fixedly connected to a limiting ring 222, which is used to improve the rotation stability of the gear shaft 220; both ends of the driving gear 223 have retaining rings 224, which are used to contact the two end surfaces of the driven gear 232 respectively, thereby suppressing the movement of the two crankshafts 230 relative to the gear shaft 220, and improving the stability of relative motion.

[0043] The shell 210 includes a pair of end covers 213 in the front-to-back direction, and a side sealing plate 211 is fixedly connected between the two end covers 213. Only the lower end of the entire shell 210 is open, and the other side walls are closed. The inner wall of the side sealing plate 211 is fixedly connected to a shaft frame 212 for cooperating with the main journal 231 to form a rotating pair. The crankshaft 230 includes a plurality of main journals 231. In this embodiment, the main journal 231 is divided into three coaxial sections. The main journals 231 located at both ends cooperate with the two end covers 213 to form a rotating pair, and the two ends of the stepped shaft 221 also cooperate with the end covers 213 to form a rotating pair. A secondary journal 234 is fixedly connected between the main journals 231 through a crank arm 233, and the axis of the secondary journal 234 is not coaxial with the axis of the main journal 231. The auxiliary journal 234 is movably connected to the slider 250 through a movable rod 240. The inner wall of the end cover 213 is provided with a side slide groove 214 for cooperating with the slider 250 to form a sliding pair, thereby limiting the freedom of movement of the slider 250. The upper end of the movable rod 240 is provided with an upper sleeve 241 for cooperating with the auxiliary journal 234 to form a rotating pair. The top of the slider 250 is provided with a fitting groove 251. The slider 250 is fixedly connected with a connecting rod shaft 252 in the fitting groove 251. The lower end of the movable rod 240 is provided with a lower sleeve 242 for cooperating with the connecting rod shaft 252 to form a rotating pair. In this way, when the crankshaft 230 rotates, it will drive the slider 250 to reciprocate.

[0044] The slider 250 will also cooperate with the upper die 4 to form a sliding pair, because the upper die 4 is provided with a through groove 402, which is just for the slider 250 to pass through to form a sliding pair, further improving the movement stability of the slider 250. The specific structure of the punch head 8 includes a swing arm 801, and the end of the swing arm 801 is rotatably connected to the upper die 4. The bottom surface of the upper die 4 has a support foot 401, and an accommodating cavity 403 is formed between the two support feet 401 on the left or the right. The accommodating cavity 403 is fixedly connected to the limiting shaft 404. One end of the swing arm 801 is provided with an axial hole 802, which just cooperates with the limiting shaft 404 to form a rotating pair. The other end of the swing arm 801 has an extrusion handle 805. The shape of the extrusion handle 805 is similar to that of the cavity 303, and is used to completely press the metal sheet into the cavity 303. Because the swing arm 801 is always inclined In order to make the extrusion handle 805 contact the metal sheet first, the extrusion handle 805 is located at the lower end of the swing arm 801, and the lower surface of the lower end of the extrusion handle 805 also has a pressure plate 804, which is used to press the metal sheet against the straight inner wall of the cavity 303, so that the molded part has not only a curved part but also a straight part. The swing arm 801 is provided with a sliding hole 803 passing through the front and rear side walls near the lower end, and the lower end of the slider 250 passes through the upper mold 4 and cooperates with the sliding hole 803 to form a sliding pair. Specifically: a yield groove 253 is provided at the bottom of the slider 250, and the slider 250 is fixedly connected with a sliding shaft 254 in the yield groove 253, which can cooperate with the sliding hole 803 to form a rotating pair and a sliding pair. That is to say, the swing arm 801 can slide and rotate relative to the slider 250 at the same time, thereby ensuring the freedom of movement of the punch head 8.

[0045] A feeding mechanism 7 is provided on the back of the upper mold 4 for providing the raw material sheet 9 to be stamped, that is, the above-mentioned metal sheet, to the lower mold 3. The feeding mechanism 7 includes a storage bin 710 fixedly connected to the back of the upper mold 4. The storage bin 710 is hollow and can store stacked raw material sheets 9 inside.

The spacing between the inner top wall and the inner bottom wall of the slide 714 should be greater than the thickness of a single raw material sheet 9 and less than the thickness of two raw material sheets 9. The horizontal width of the discharge slide 714 should also be slightly greater than the horizontal width of the raw material sheet 9. There is no such requirement for the insertion slide 713. A pushing piece 740 is provided at the rear of the storage bin 710, which can pass through the insertion slide 713 to allow the raw material sheet 9 at the bottom of the storage bin 710 to slide out of the discharge slide 714 and translate into the positioning groove 302 on the upper surface of the lower mold 3. Because a part of the metal sheet will remain in the positioning groove 302 even after being formed, when the feeding mechanism 7 pushes the new raw material sheet 9 to the upper surface of the lower mold 3, the new raw material sheet 9 will push the molded part out of the cavity 303, thereby realizing automatic loading and unloading.

[0046] An openable door 711 is provided on the back of the storage bin 710. After the door 711 is opened, the raw material sheets 9 can be quickly replenished into the storage bin 710.

The raw material viewing window 712 is made of transparent tempered glass, which is convenient for the staff to observe the remaining amount of raw material sheets 9 in the storage bin 710, providing a good basis for when to replenish the raw material sheets 9. A guide rail 720 close to the bottom surface is also provided on the back of the storage bin 710. The guide rail 720 includes a baffle plate 721 fixedly connected to the storage bin 710 for shielding moving parts, so that the entire stamping equipment is less affected by the outside world during operation and the operation is safer. A rib plate 722 is fixedly connected between the upper surface of the baffle plate 721 and the rear side surface of the storage bin 710 for improving the installation stability of the baffle plate 721 , the lower surfaces of both sides of the baffle plate 721 are fixedly connected with support plates 723 for providing lifting force to the moving parts, and a guide slide 724 is formed between the upper surface of the support plate 723 and the lower surface of the baffle plate 721; and the specific structure of the pusher 740 includes a straight top plate 742, the thickness of the top plate 742 is equivalent to the thickness of the raw material sheet 9, the two sides of the top plate 742 are located above the support plate 723, and just cooperate with the guide slide 724 to form a sliding pair, the rear end of the top plate 742 is provided with a traction plate 741 extending downward, which is an integral structure with the top plate 742, and the transition between the two is thickened to avoid relative bending; the bottom of the storage bin 710 is provided with an extension plate 715, and a hydraulic cylinder 730 is connected between the extension plate 715 and the traction plate 741, which is used to drive the pusher 740 to reciprocate back and forth.

[0047] Working principle: The electric telescopic rod 505 drives the lower die 3 to adjust its height under the control of the industrial computer, so that the bottom surface of the positioning groove 302 is flush with the inner bottom surface of the storage bin 710. The servo motor 101 and the hydraulic cylinder 730 also work together under the control of the industrial computer. The hydraulic cylinder 730 drives the pusher 740 to push the raw material sheet 9 onto the lower die 3. The servo motor 101 rotates at a constant speed through the transmission mechanism 2 to let the lower end of the punch head 8 swing down, squeezing the raw material sheet 9 into the cavity 303 to form a molded part. The servo motor 101 continues to rotate, the secondary journal 234 moves up, the slider 250 allows the lower end of the punch head 8 to swing up, the extrusion handle 805 moves out of the cavity 303 and separates from the molded part, the hydraulic cylinder 730 drives the pusher 740 to return to the initial position, the raw material sheet 9 in the storage bin 710 moves down, the bottom raw material sheet 9 is flush with the ejector plate 742, and the above actions are repeated.
