Description

Technical Field

[0001] The present invention belongs to the field of sheet metal stamping, and particularly relates to a stamping device for the production of automobile oil sumps. Background Art

[0002] The oil sump is an important part of the engine and is located in the lower half of the crankcase. Its main functions are to seal the crankcase, collect and store lubricating oil, prevent impurities from entering, and help the lubricating oil dissipate heat and precipitate impurities. Traditional oil sumps are mostly made of thin steel plates through stamping processes, and their structures usually include components such as a housing and a baffle. For example, some construction machinery oil sumps have characteristics such as a large oil storage capacity, a basically symmetrical shape, and deep ribs at both shoulder ends. During the stamping process of an oil sump with such a structure, due to the complexity of its shape and size, relatively high requirements are imposed on the design and manufacturing of stamping dies.

[0003] In the prior art, the stamping of thin steel plates is usually carried out by pressing with an upper die and a lower die. During the manufacturing process, the thin steel plate will be embossed or trimmed. The manufacturing principle is to correspondingly set bosses or grooves on the upper die and the lower die, and the design effect is achieved through cold pressing. During production, usually the lower die is fixed and the upper die moves up and down. And before stamping, the thin steel plate needs to be set on the lower die, and suction holes are opened on the lower die, and the thin steel plate is positioned on the lower die by means of vacuum adsorption.

[0004] In the prior art, the thickness of the thin steel plate is usually 2 mm - 5 mm. If the steel plate has internal stress or poor stiffness, it will cause the steel plate to have a bending arc as shown in Figure 11 When placed on the lower die, the suction holes will not firmly suck or there will be a phenomenon of steel plate misalignment, resulting in poor dimensions of the produced finished products. And in some manufacturing processes, in order to generate specific process parameters, steel plates with stress are deliberately used, which poses a challenge to the accuracy of automatic feeding of curved steel plates.

[0018] Compared with the prior art, the stamping device for producing an automobile oil pan of the present invention has the following beneficial effects: (1) For the stamping device for producing an automobile oil pan of the present invention, the first material grasping assembly can flatten and pick up a steel plate with stress or curvature, then place it on the positioning assembly for origin return of the steel plate, and then the second material grasping assembly flattens and picks up the steel plate and places it on the stamping assembly.

And there is no manual participation in the process, reducing the production intensity and ensuring the production efficiency.

[0019] (2) For the stamping device for producing an automobile oil pan of the present invention, an external vacuum pumping device is connected to the suction trays through an air pipe. Multiple suction trays act together on the steel plate to realize the suction connection of the steel plate. And before the suction trays suck the steel plate, the material can be flattened through the pressing plate to realize the flattening and picking up of the steel plate.

[0020] (3) For the stamping device for producing an automobile oil pan of the present invention, the floating assembly is a floating structure in which a robotic arm drives the pressing plate and the suction trays to approach the steel plate. When the robotic arm drives the pressing plate to press against the upper end of the steel plate and the robotic arm continues to move downward, when the pressing plate is interfered by the steel plate and stops moving, the support plate continues to press down. At this time, the first sliding rod and the first sliding sleeve move relative to each other, causing the abutting platform to touch the first microswitch, indicating that the robotic arm has moved in place, and then the suction trays suck the steel plate.

[0021] (4) For a stamping device used in the production of an automobile oil pan according to the present invention, the lower end of the steel plate is suction-connected to the upper end of the fourth support plate. Two vertically arranged pushing plates are used to push and position the two sides of the steel plate, so as to make the other two sides of the steel plate abut against the L-shaped structure of the positioning plate.

In order to facilitate the separation of the steel plate from the positioning plate, slope-shaped openings are respectively arranged on the inner side of each side of the L-shaped structure of the positioning plate.

[0022] (5) For a stamping device used in the production of an automobile oil pan according to the present invention, during implementation, there will be cumulative errors after the robotic arm of the second material grasping component moves repeatedly for many times. It is necessary to position the origin of the movement of the robotic arm. A reset component is arranged below the second material grasping component, and it can be set that after the second material grasping component moves multiple times, it is reset through the reset component to ensure the feeding accuracy of the steel plate.

[0023] (6) For a stamping device used in the production of an automobile oil pan according to the present invention, the first touch switch is a reset switch for the vertical direction of the second material grasping component, that is, the Z-direction reset switch. When the robotic arm drives the second material grasping component to move towards the sixth support plate, the second material grasping component drives the sixth support plate to press down the second sliding rod. At this time, the second sliding sleeve remains stationary. When the abutting rod abuts against the first touch switch, it means that the robotic arm has moved down in place; Two second touch switches vertically arranged on the alignment plate are respectively set as reset switches for the X-direction and Y-direction of the robotic arm. When the two sides of the robotic arm driving the second material grasping component respectively contact the two second touch switches, it means that the robotic arm has moved in place in the X-direction and Y-direction. In order to avoid hard friction contact between the sixth support plate and the pressing plate, a plurality of universal ball bearings are evenly distributed on the sixth support plate.

The first material gripping component 2 is used to flatten and pick up the steel plate on the material rack 1 and place it on the positioning component 3. The positioning component 3 is used for the origin positioning of the steel plate during loading. The second material gripping component 4 is used to transfer the steel plate on the positioning component 3 to the stamping component 5. The first material gripping component 2 can flatten and pick up the steel plate with stress or curvature, then place it on the positioning component 3 to perform origin return on the steel plate, and then the second material gripping component 4 flattens and picks up the steel plate and places it on the stamping component 5. The stamping component 5 adsorbs and positions through the self-provided air suction holes, ensuring the consistency of the feeding of the steel plate with stress or curvature, so as to ensure the quality of the forming in the subsequent processes. Moreover, there is no manual participation in the process, reducing the production intensity and ensuring the production efficiency.

[0031] The first material gripping component 2 and the second material gripping component 4 are respectively externally connected to a robotic arm, and the structures of the first material gripping component 2 and the second material gripping component 4 are the same. The first material gripping component 2 includes a crimping plate 21 and a suction cup 22. A plurality of first through holes are provided on the crimping plate 21, and each first through hole corresponds to a suction cup 22. The suction cup 22 is installed at one end of an air pipe 23. A floating component 24 is provided on the crimping plate 21. Both the air pipe 23 and the floating component 24 are connected to a support plate 25, and the support plate 25 is arranged at one end of the robotic arm. The robotic arm is a six-axis robotic arm of the prior art, such as a double-rotation six-axis robotic arm of model KOZA KZH-BR61. Based on being able to drive the first material gripping component 2 and the second material gripping component 4 to move, technicians can adapt it by themselves, which will not be elaborated here. An external vacuum device is connected to the suction cup 22 through the air pipe 23. The plurality of suction cups 22 act together on the steel plate to realize the suction connection of the steel plate. And before the suction cup 22 sucks the steel plate, the material can be flattened by the crimping plate 21 to realize the flattening and picking up of the steel plate.

[0032] The floating component 24 includes a first slide bar 241 and a first slide sleeve 242. The outer periphery of the first slide bar 241 is slidably connected to the inside of the first slide sleeve 242. One end of the first slide sleeve 242 is fixedly connected to the support plate 25.

One end of the first spring 244 is fixedly connected to a first support plate. The first support plate is fixedly installed inside the first slide sleeve 242. A first branch pipe 245 is provided on the first support plate. The first spring 244 is located on the outer periphery of the first branch pipe 245. One end of the first branch pipe 245 is provided with a first retaining ring, and a first microswitch 246 is slidably arranged inside the first retaining ring.

When the robotic arm drives the crimping plate 21 to be pressed tightly against the upper end of the steel plate and the robotic arm continues to move downward, when the crimping plate 21 is interfered by the steel plate and stops moving, the support plate 25 continues to press down. At this time, the first slide bar 241 and the first slide sleeve 242 move relative to each other, causing the abutting platform to touch the first microswitch 246, which means the robotic arm has moved in place. Then the steel plate is sucked by the suction cup 22.

[0033] After the robotic arm moves into place, if the robotic arm is lifted, the first slide bar 241 and the first sliding sleeve 242 will be elastically reset by the first spring 244.
