Description

Technical Field

[0001] The utility model relates to the technical field of stamping devices, in particular to a stamping device for manufacturing automobile body parts. Background Art

[0002] A car is generally composed of a body, power components, electronic components and other parts. During the processing of the body, some parts of the body need to be stamped and formed by a stamping mechanism.

[0003] When using existing stamping devices for manufacturing automotive body parts, workers generally need to manually place the parts to be stamped into the corresponding cavity, and then control the downward movement of the punch to stamp the parts in the cavity. However, during the loading process, the workers' hands will extend under the punch due to manual loading. When the stamping mechanism fails or an accident occurs, the downward movement of the punch can easily crush the workers' hands, resulting in poor performance. Moreover, after the stamping is completed, the workers need to manually remove the molded parts from the cavity, which is troublesome. To this end, we propose a stamping device for manufacturing automotive body parts. Utility Model Content

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Reference Figure 1-Figure 5 A stamping device for manufacturing automobile body parts includes a base 1, a control cabinet 37 is installed on one side of the bottom of the base 1, and a controller is provided inside the control cabinet 37. The controller is one of a control motherboard, a host or a PLC logic controller.

[0032] like Figure 1 As shown, a U-shaped frame 9 is installed on the top of the base 1, and a first fixed plate 12 is provided inside the U-shaped frame 9. The top of the first fixed plate 12 is connected to the top of the U-shaped frame 9 through a first hydraulic rod 10. The first hydraulic rod 10 is connected to the controller through a wire, and the first hydraulic rod 10 can control the lifting of the first fixed plate 12.

[0033] It should be noted that if Figure 1 As shown, at least one first guide rod 11 is installed on the top edge of the first fixed plate 12. The top of the first guide rod 11 slides through the top of the U-shaped frame 9. The first guide rod 11 can limit and guide the first fixed plate 12, so that the first fixed plate 12 can remain stable.

[0034] like Figure 1 and Figure 3As shown, a punch 29 is installed at the bottom of the first fixed plate 12, a support platform 28 is installed on the top of the base 1, a mold 24 is provided on the top of the support platform 28, and a cavity 23 matching the punch 29 is opened on the top of the mold 24. The cavity 23 is located below the punch 29. During actual use, the first hydraulic rod 10 can push the first fixed plate 12 downward, so that the bottom of the punch 29 moves into the cavity 23, and the workpiece in the cavity 23 is punched and formed.

[0035] like Figure 2 and Figure 5 As shown, two fixing seats 26 are symmetrically installed on the top of the base 1, and a rotating shaft 25 is rotatably connected between the two fixing seats 26. Bar connecting blocks 27 are installed on both ends of the side of the rotating shaft 25. One end of each bar connecting block 27 extends to the side of the mold 24, and both sides of the mold 24 are connected to the side of the bar connecting block 27. In actual use, the mold 24 can be connected to the rotating shaft 25 through the bar connecting block 27, so that when the rotating shaft 25 rotates, it will drive the mold 24 to rotate along the rotating shaft 25.

[0036] like Figure 2 and Figure 5 As shown, both ends of the rotating shaft 25 pass through the fixed seat 26, and gears 13 are installed at both ends of the rotating shaft 25. Two bar-shaped movable plates 3 are symmetrically installed on the top of the base 1. A rack 2 is installed on the top of each bar-shaped movable plate 3. The rack 2 is engaged with the corresponding gear 13. In actual use, the gear 13 can be rotated by moving the rack 2, and the position of the mold 24 can be adjusted as needed.

[0037] like Figure 5 As shown, a first through slot 4 is symmetrically provided on the top of the base 1, and a first sliding block 34 is installed at the bottom of each strip-shaped movable plate 3, and the bottom of each first sliding block 34 extends to the bottom of the first through slot 4, and the two first sliding blocks 34 are connected by a strip-shaped fixed block 33, and a fourth hydraulic rod 32 is installed on one side of the strip-shaped fixed block 33, and the other end of the fourth hydraulic rod 32 is fixed to the bottom of the base 1 through the second connecting plate 31, and the fourth hydraulic rod 32 is connected to the controller through a wire, and the rack 2 can be driven to move horizontally by the extension and retraction of the fourth hydraulic rod 32, thereby controlling the flipping of the mold 24, and facilitating the removal of the workpiece stamped in the mold 24.

[0038] It should be noted that a blanking chute 8 is provided on one side of the top of the base 1, and when the mold 24 is flipped 180°, the mold 24 is located above the blanking chute 8. A storage plate 6 is also provided at the bottom of the base 1. The top edge of the storage plate 6 is fixed to the base 1 through a number of railings. A collection box 5 is provided on the top of the storage plate 6. The collection box 5 is located below the blanking chute 8. After the stamping is completed, the mold 24 can be controlled to flip 180° through the fourth hydraulic rod 32. In this way, the mold 24 will flip to the top of the blanking chute 8. Under the action of gravity and inertia, the workpiece in the cavity 23 will fall into the inside of the collection box 5 along the blanking chute 8 to complete the collection.

[0039] like Figure 1 and Figure 4 As shown, a mounting seat 20 is provided on one side of the top of the base 1, and a second sliding block 35 is installed on the bottom of the mounting seat 20. A second through slot 19 is opened on one side of the top of the base 1, and the bottom of the second sliding block 35 extends below the second through slot 19, and one side of the bottom of the second sliding block 35 is fixedly connected to the second connecting plate 31 through a third hydraulic rod 30. The third hydraulic rod 30 is connected to the controller through a wire. In actual use, the mounting seat 20 can be driven to move horizontally along the guide rail by the third hydraulic rod 30.

[0040] If explanation is required, Figure 1 As shown, the bottom of the mounting seat 20 is slidably connected to the guide rail fixed on the top of the base 1 through a slider. With the cooperation of the guide rail and the slider, the mounting seat 20 can be limited so that the mounting seat 20 remains stable.

[0041] like Figure 4 As shown, a second fixing plate 17 is installed on the top of the mounting seat 20, and two second strip-shaped mounting plates 16 are symmetrically provided on the top of the second fixing plate 17. Two strip-shaped clamping plates 18 are symmetrically provided between the two second strip-shaped mounting plates 16. One end of each strip-shaped clamping plate 18 extends to one side of the second fixing plate 17. A receiving groove 14 is opened on one side of the top of each strip-shaped clamping plate 18. When the two strip-shaped clamping plates 18 are close to each other, the two receiving grooves 14 form an accommodating cavity, and the workpiece to be stamped is placed in the accommodating cavity. The bottom of the shaped clamping plate 18 is flush with the top of the mold 24, and when one side of the second sliding block 35 is in contact with one end of the second through groove 19, the accommodating groove 14 is located directly above the cavity 23. During actual use, the staff can place the workpiece into the accommodating groove 14, and then move the workpiece above the cavity 23 through the third hydraulic rod 30. In this way, the staff does not need to place the workpiece in the cavity 23 by hand. In the event of damage to the stamping mechanism or an accident, the staff's hands will not be squeezed by the punch 29.

[0042] like Figure 1 and Figure 4As shown, a first strip mounting plate 15 is installed on one side of the top of each strip clamping plate 18, and one side of each first strip mounting plate 15 is connected to the corresponding second strip mounting plate 16 through a second hydraulic rod 21. The second hydraulic rod 21 is connected to the controller through a wire. The second hydraulic rod 21 can control the distance between the two strip clamping plates 18 to clamp and fix the workpiece placed in the accommodating groove 14 so that the workpiece will not shift during the movement.

[0043] Specifically, when the present invention is in use, the worker places the workpiece between the two receiving grooves 14, and then controls the second hydraulic rod 21 to extend through the controller, and the second hydraulic rod 21 pushes the two strip clamping plates 18 to move relative to each other, clamping the workpiece in the receiving groove 14, and then the worker controls the third hydraulic rod 30 to retract through the controller, and the third hydraulic rod 30 drives the mounting seat 20 to move horizontally, so that the workpiece clamped by the strip clamping plate 18 moves to the top of the cavity 23, and then controls the second hydraulic rod 21 to retract, and the strip clamping plate 18 separates from the workpiece, and the workpiece falls into the cavity 23 under the action of gravity, and then the strip clamping plate 18 is removed from above the mold 24 by the third hydraulic rod 30 to complete the loading, and then the controller controls the third hydraulic rod 30 to retract. A hydraulic rod 10 extends, pushing the punch 29 into the cavity 23 to stamp the workpiece. After the processing is completed, the first hydraulic rod 10 contracts to move the punch 29 out of the cavity 23. Then the staff controls the fourth hydraulic rod 32 to contract. The fourth hydraulic rod 32 drives the rack 2 to move horizontally. The gear 13 rotates under the action of the rack 2, thereby causing the mold 24 to flip along the rotating shaft 25. When the mold 24 flips to 180°, the cavity 23 on the mold 24 is located above the blanking chute 8. Under the action of gravity and inertia, the workpiece in the cavity 23 falls along the blanking chute 8 into the collection box 5 for collection. Afterwards, the fourth hydraulic rod 32 extends, causing the gear 13 to flip, and the mold 24 returns to its original position for the stamping of the next workpiece.

[0044] Furthermore, if Figure 5 As shown, a limiting rod 36 is installed inside each first through groove 4, and each limiting rod 36 slides through the corresponding first sliding block 34. With the cooperation of the limiting rod 36, the first sliding block 34 can be guided, so that the first sliding block 34 can remain stable during movement, and the rack 2 will not shake during movement.

[0045] Furthermore, if Figure 4 As shown, each first strip mounting plate 15 is installed with at least one second guide rod 22 on one side close to the second strip mounting plate 16, and one end of each second guide rod 22 slides through the corresponding second strip mounting plate 16. Under the action of the second guide rod 22, the first strip mounting plate 15 can be limited, so that the position of the strip clamping plate 18 will not be offset during movement.

[0046] Furthermore, if Figure 1 As shown, a plurality of legs 7 are installed on the bottom edge of the base 1, and the bottom of the legs 7 extends to the bottom of the control cabinet 37 and the storage plate 6. The legs 7 can support the base 1 and ensure that there is a distance between the control cabinet 37 and the storage plate 6 and the ground, so that the bottom of the control cabinet 37 and the storage plate 6 will not collide with the ground and be damaged.

[0047] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
