Description

Technical Field

[0001] This utility model relates to the technical field of stamping devices, and in particular to a metal part stamping forming device. Background Technology

[0002] Stamping is a type of material forming. The main method of stamping is to place the material on the lower die and use a press to drive the upper and lower dies to close, thereby stamping the metal parts into shape.

[0003] Chinese utility model patent CN217166009U discloses a metal part stamping forming device. This device includes a lower die base and guide pillars, with the guide pillars fixedly disposed on both sides of the lower die base. The lower die base has a lower cavity and side holes. A top plate is fixedly connected to the end of the guide pillars away from the lower die base. A clamping mechanism is installed in the lower cavity of the lower die base, with its power output end disposed in a hole. A lower die is disposed on the lower die base and fixed by the clamping mechanism. An upper die base is slidably sleeved on the guide pillars and has an upper cavity, with an upper die disposed on it. A clamping device is installed in the upper cavity. A drive mechanism is fixedly disposed on the top plate, with its power output end connected to the upper die base. This utility model provides a metal part stamping forming device that can not only stamp metal parts but also fix the upper and lower dies, avoiding adjustments to the dies during continuous production. It is simple to operate and highly practical.

[0004] However, the existing technology described above requires removing the metal parts from the lower die after stamping, which is labor-intensive. Furthermore, if the upper die falls during the removal process, it will cause danger and result in poor safety. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a metal part stamping and forming device that can flip the lower die out of the upper die, facilitate the unloading of metal parts, reduce labor intensity, and improve safety.

[0006] This utility model discloses a metal part stamping forming device, comprising a base, a column, and a hydraulic cylinder. The column is mounted on the base, and the fixed end of the hydraulic cylinder is mounted on the column. It also includes a lower base plate, an upper base plate, a lower connecting rod, and an upper connecting rod. The front end of the lower base plate is rotatably connected to the front end of the base, and the lower end face of the lower base plate rests on the upper end face of the base. A lower die is mounted on the upper end face of the lower base plate. The upper base plate is mounted on the lower end of the piston rod of the hydraulic cylinder, and the upper die is mounted on the lower end face of the upper base plate. The upper and lower dies are arranged opposite to each other. The lower end of the lower connecting rod is rotatably connected to the middle of the side of the lower base plate, and the upper end of the lower connecting rod is rotatably connected to the lower end of the upper connecting rod. The upper end of the upper connecting rod is rotatably connected to the front end of the side wall of the upper base plate. During operation, the piston rod of the hydraulic cylinder retracts, lifting the upper base plate and causing the upper die to disengage from the lower die. In this process, when the upper substrate stretches the upper and lower connecting rods to collinearity, the hydraulic cylinder stops operating, and the metal blank is placed into the lower die. The piston rod of the hydraulic cylinder extends, causing the upper substrate to descend, so that the upper die presses against the lower die to stamp the metal part. The piston rod of the hydraulic cylinder retracts, lifting the upper substrate and separating the upper and lower dies. At the same time, the upper substrate pulls the lower substrate through the upper and lower connecting rods, causing it to rotate and flip upward around the front end of the lower substrate. This moves the lower die out of front of the upper die, and the metal part in the lower die falls out under gravity. After unloading, the same operation is repeated for the next stamping. Compared with existing technologies, this method makes it easier to remove the metal part from the lower die, reducing labor intensity. During the part removal process, the lower die is located outside the upper die, reducing the danger and improving safety.

[0007] Preferably, it also includes multiple lower slots and multiple upper slots. Multiple lower slots are evenly arranged on the upper end surface of the lower substrate, and multiple upper slots are evenly arranged on the lower end surface of the upper substrate. By setting multiple lower slots, it is convenient to adjust the position of the lower mold on the lower substrate. By setting multiple upper slots, it is convenient to adjust the position of the upper mold on the upper substrate. It can also install upper and lower molds of different sizes, and has good versatility.

[0008] Preferably, it also includes a rotating shaft and a torsion spring. The front end of the lower substrate is rotatably connected to the bearing seat at the front of the base via the rotating shaft. One end of the torsion spring is connected to the rotating shaft, and the other end of the torsion spring is connected to the base. The elastic force of the torsion spring presses the lower end face of the lower substrate against the base. The front end of the lower substrate is rotatably connected to the base via the rotating shaft. When the upper substrate descends, the elastic force of the torsion spring twists the lower substrate downward through the rotating shaft, so that the lower end face of the lower substrate is pressed against the base, thereby improving the stability of the lower substrate.

[0009] Preferably, it also includes a horizontal frame, a vertical frame, and a gripping component. A groove is provided at the front of the base. The horizontal frame is slidably inserted into the groove of the base. The vertical frame is installed on the outer end of the horizontal frame. The gripping component is installed on the vertical frame and faces the inner side of the base. When the lower base plate drives the lower mold to flip to the outside of the upper mold, the horizontal frame is pushed into the groove of the base, so that the horizontal frame drives the vertical frame and the gripping component to approach the lower mold. This allows the gripping component to adsorb the formed metal part. The horizontal frame is pulled out of the groove of the base, so that the gripping component adsorbs the metal from the lower mold, achieving efficient and safe material feeding with good practicality.

[0010] Preferably, it also includes a mounting groove and bolts. A vertical mounting groove is provided on the vertical frame, and the gripping component is installed in the mounting groove by bolts. The installation position of multiple bolts is adjusted along the mounting groove, thereby adjusting the height of the gripping component, so that the gripping component can adapt to molds of different sizes and improve versatility.

[0011] Preferably, it also includes a track groove and a slide rail. The bottom of the slide groove of the base is provided with a track groove, and the slide rail is installed on the lower end face of the cross frame. The slide rail is slidably connected with the track groove. The cross frame is slidably inserted into the slide groove of the base through the slide rail and the track groove. The cooperation of the slide rail and the track groove makes the cross frame slide smoothly and stably. The technology is mature and reliable.

[0012] Preferably, it also includes a gear and a rack. The gear is installed at the front end of the lower substrate and is concentric with the rotating shaft. The rack is installed on the crossbeam and meshes with the gear. When the lower substrate is flipped up and the lower mold is moved outward, the lower substrate drives the gear to rotate. The gear meshes with the rack and drives the crossbeam to move inward, so that the gripping component approaches the lower mold to adsorb the metal part. When the lower substrate is flipped down and the lower mold is moved inward, the lower substrate drives the gear to reverse. The gear meshes with the rack and drives the crossbeam to move outward, so that the gripping component takes the metal part out of the lower mold, realizing linked feeding. After the lower substrate is flattened and the lower connecting rod and the upper connecting rod are collinear, the upper mold is still located above the lower mold. At this time, the blank of the metal part is put into the lower mold, improving working efficiency.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: During operation, the piston rod of the hydraulic cylinder retracts to lift the upper base plate, causing the upper mold to separate from the lower mold. When the upper base plate stretches the upper connecting rod and the lower connecting rod to collinearity, the hydraulic cylinder stops operating, and the metal blank is placed into the lower mold. The piston rod of the hydraulic cylinder extends to lower the upper base plate, causing the upper mold to press against the lower mold to stamp the metal part. The piston rod of the hydraulic cylinder retracts to lift the upper base plate, causing the upper mold to separate from the lower mold. At the same time, the upper base plate pulls the lower base plate through the upper connecting rod and the lower connecting rod to rotate around the front end of the lower base plate and flip upward, thereby moving the lower mold out of front of the upper mold and causing the metal part in the lower mold to fall off under gravity. After the part is unloaded, the above operation is repeated for the next stamping. Compared with the prior art, it is easier to remove the metal part from the lower mold, reducing labor intensity. During the part removal process, the lower mold is located outside the upper mold, reducing the danger and improving safety. Attached Figure Description

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0022] like Figures 1 to 5 As shown, a metal stamping forming apparatus includes a base 1, a column 2, and a hydraulic cylinder 3. The column 2 is mounted on the base 1, and the fixed end of the hydraulic cylinder 3 is mounted on the column 2. It also includes a lower base plate 4, an upper base plate 5, a lower connecting rod 6, and an upper connecting rod 7. The front end of the lower base plate 4 is rotatably connected to the front end of the base 1, and the lower end surface of the lower base plate 4 rests on the upper end surface of the base 1. A lower die is mounted on the upper end surface of the lower base plate 4. The upper base plate 5 is mounted on the lower end of the piston rod of the hydraulic cylinder 3, and the upper die is mounted on the lower end surface of the upper base plate 5. The upper and lower dies are arranged opposite to each other. The lower end of the lower connecting rod 6 is rotatably connected to the middle of the side surface of the lower base plate 4. Next, the upper end of the lower connecting rod 6 is rotatably connected to the lower end of the upper connecting rod 7, and the upper end of the upper connecting rod 7 is rotatably connected to the front end of the side wall of the upper base plate 5; it also includes multiple lower slots 8 and multiple upper slots 9, with multiple lower slots 8 evenly arranged on the upper end surface of the lower base plate 4 and multiple upper slots 9 evenly arranged on the lower end surface of the upper base plate 5; it also includes a rotating shaft 10 and a torsion spring 11, with the front end of the lower base plate 4 rotatably connected to the bearing seat at the front of the base 1 through the rotating shaft 10, one end of the torsion spring 11 connected to the rotating shaft 10, and the other end of the torsion spring 11 connected to the base 1, and the elastic force of the torsion spring 11 pressing the lower end surface of the lower base plate 4 against the base 1.

[0023] Multiple lower slots 8 facilitate adjustment of the lower die's position on the lower base plate 4, and multiple upper slots 9 facilitate adjustment of the upper die's position on the upper base plate 5, allowing for the installation of upper and lower dies of different sizes. The front end of the lower base plate 4 is rotatably connected to the base 1 via a rotating shaft 10. During operation, the piston rod of the hydraulic cylinder 3 retracts, lifting the upper base plate 5 and disengaging the upper and lower dies. When the upper base plate 5 stretches the upper connecting rod 7 and the lower connecting rod 6 until they are collinear, the hydraulic cylinder 3 stops operating, and the metal blank is placed into the lower die. The piston rod of the hydraulic cylinder 3 extends, causing the upper base plate 5 to descend, pressing the upper die against the lower die to stamp the metal part. As the upper base plate 5 descends, the torsion spring 11... The elastic force of the upper plate 4 is twisted downward through the rotating shaft 10, so that the lower end face of the lower plate 4 is pressed against the base 1. The piston rod of the hydraulic cylinder 3 retracts to lift the upper plate 5, so that the upper mold is separated from the lower mold. At the same time, the upper plate 5 pulls the lower plate 4 around the front end of the lower plate 4 and flips it upward through the upper connecting rod 7 and the lower connecting rod 6, so that the lower mold moves out of front of the upper mold and the metal part in the lower mold falls off under gravity. After the part is unloaded, the above operation is repeated for the next stamping. Compared with the existing technology, it is easier to remove the metal part from the lower mold, reducing labor intensity. During the part removal process, the lower mold is located outside the upper mold, which reduces the danger and improves safety. Example 2

[0024] like Figures 1 to 4 and Figure 6As shown, based on Embodiment 1, it also includes a horizontal frame 12, a vertical frame 13, and a gripping component 14. A sliding groove is provided at the front of the base 1, and the horizontal frame 12 is slidably inserted into the sliding groove of the base 1. The vertical frame 13 is installed on the outer end of the horizontal frame 12, and the gripping component 14 is installed on the vertical frame 13, with the gripping component 14 facing the inner side of the base 1. It also includes a mounting groove 15 and bolts 16. A vertical mounting groove 15 is provided on the vertical frame 13, and the gripping component 14 is installed in the mounting groove 15 by bolts 16. It also includes a track groove 17 and a slide rail 18. A track groove 17 is provided at the bottom of the sliding groove of the base 1, and the slide rail 18 is installed on the lower end face of the horizontal frame 12, with the slide rail 18 slidably connected to the track groove 17.

[0025] Adjust the installation positions of multiple bolts 16 along the mounting groove 15 to adjust the height of the gripping component 14, so that the gripping component 14 can adapt to molds of different sizes. The horizontal frame 12 is slidably inserted into the groove of the base 1 through the slide rail 18 and the track groove 17. The slide rail 18 and the track groove 17 cooperate to make the horizontal frame 12 slide smoothly and stably. When the lower base plate 4 drives the lower mold to flip to the outside of the upper mold, the horizontal frame 12 is pushed into the groove of the base 1, so that the horizontal frame 12 drives the vertical frame 13 and the gripping component 14 to approach the lower mold, so that the gripping component 14 adsorbs the formed metal part, and pulls the horizontal frame 12 out of the groove of the base 1, so that the gripping component 14 adsorbs the metal from the lower mold, achieving efficient and safe material feeding. Example 3

[0026] like Figure 5 and Figure 6 As shown, based on Embodiment 2, it also includes a gear 19 and a rack 20. The gear 19 is installed at the front end of the lower base plate 4 and is concentric with the rotating shaft 10. The rack 20 is installed on the cross frame 12 and meshes with the gear 19. When the lower base plate 4 is flipped up and the lower mold is moved outward, the lower base plate 4 drives the gear 19 to rotate. The gear 19 meshes with the rack 20 and drives the cross frame 12 to move inward, so that the gripping component 14 approaches the lower mold to adsorb the metal part. When the lower base plate 4 is flipped down and the lower mold is moved inward, the lower base plate 4 drives the gear 19 to reverse. The gear 19 meshes with the rack 20 and drives the cross frame 12 to move outward, so that the gripping component 14 takes the metal part out of the lower mold, realizing linkage feeding. After the lower base plate 4 is flattened and the lower connecting rod 6 and the upper connecting rod 7 are collinear, the upper mold is still located above the lower mold. At this time, the blank of the metal part is put into the lower mold, improving the working efficiency.

[0027] like Figures 1 to 6As shown, this utility model discloses a metal part stamping forming device. During operation, the piston rod of the hydraulic cylinder 3 first retracts, lifting the upper base plate 5, causing the upper die to separate from the lower die. When the upper base plate 5 stretches the upper connecting rod 7 and the lower connecting rod 6 until they are collinear, the hydraulic cylinder 3 stops operating. The metal part blank is placed into the lower die, and the piston rod of the hydraulic cylinder 3 extends, causing the upper base plate 5 to descend, pressing the upper die against the lower die to stamp the metal part. Then, the piston rod of the hydraulic cylinder 3 retracts, lifting the upper base plate 5, causing the upper die to separate from the lower die. Simultaneously, the upper base plate 5, through the upper connecting rod 7 and the lower connecting rod 6, pulls the lower base plate 4, causing it to rotate upwards around its front end, thus moving the lower die out of front of the upper die. During this process, the lower base plate 4 drives the gear 19 to rotate. The meshing rack 20 drives the crossbeam 12 to move inward, thereby bringing the gripping component 14 close to the lower die to adsorb the metal part. The piston rod of the hydraulic cylinder 3 extends, causing the upper base plate 5 to descend. The upper base plate 5, through the lower connecting rod 6 and the upper connecting rod 7, flattens the lower base plate 4 and moves the lower die inward. The lower base plate 4 drives the gear 19 to reverse. The gear 19 meshes with the rack 20 to drive the crossbeam 12 to move outward, thereby causing the gripping component 14 to remove the metal part from the lower die. Finally, after the lower base plate 4 is flattened and the lower connecting rod 6 and the upper connecting rod 7 are collinear, the upper die is still located above the lower die. At this time, the blank of the metal part is placed into the lower die. The piston rod of the hydraulic cylinder 3 continues to extend, causing the upper base plate 5 to descend, so that the upper die presses against the lower die to stamp the metal part. The above work is repeated to continuously stamp and form the part.

[0028] The main functions achieved by this utility model are:

[0029] 1. It can flip the lower mold out of the upper mold, which facilitates the unloading of metal parts, reduces labor intensity, and improves safety;

[0030] 2. The lower mold and the material handling mechanism are linked to automatically unload materials, improving work efficiency;
