Description

Technical Field

[0001] The present invention relates to the technical field of automotive component processing, and specifically to a drawing forming processing device for an automotive floor reinforcement plate. Background Art

[0002] In the drawing forming process of an automotive floor reinforcement plate, applying oil to the sheet metal is a crucial step. Drawing oil application can effectively reduce the friction between the sheet metal and the mold, reduce the risk of wear and rupture of the sheet metal during the drawing process, improve the forming quality and the service life of the mold. At the same time, oil application can also play a certain cooling role to prevent the sheet metal and the mold from deforming due to heat generated by friction. Generally, the sheet metal is divided into a drawing area and a free edge area. The drawing area is the main area where the sheet metal deforms during the forming process and requires sufficient lubrication; while the free edge area will undergo subsequent processes such as welding and gluing, and cannot be contaminated with lubricating oil, otherwise it will affect the quality of these processes.

[0003] However, in actual operation, when applying oil to the drawing area, it often occurs that the lubricating oil is applied to the free edge area. This requires further cleaning of the free edge area before subsequent processing and welding, which not only causes waste of lubricating oil, but also affects the welding and gluing effects if the cleaning is not thorough. But if the operation is too cautious to avoid applying to the free edge, it is difficult to ensure that the drawing area is fully covered, resulting in insufficient lubrication in the drawing area, thereby affecting the drawing forming quality of the sheet metal.

[0004] In view of the problems in the prior art, the present invention provides a drawing forming processing device for an automotive floor reinforcement plate.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a drawing forming processing device for an automotive floor reinforcement plate, including a bottom plate, on one side of the bottom plate is provided an oil application mechanism for drawing forming, and on the other side of the bottom plate is provided a shielding mechanism for shielding the free edge; The oil application mechanism includes an electric telescopic rod fixedly installed on one side of the bottom plate, the output end of the electric telescopic rod is fixedly connected with a mounting frame, the upper end of the mounting frame is fixedly connected with an oil tank, the mounting frame is rotatably connected with an oil application roller corresponding to the oil tank, and one side of the oil tank is fixedly connected with a pressing frame; The shielding mechanism includes a guide rod fixedly connected to the upper end of one side of the bottom plate, a convex block is fixedly connected to the middle of the guide rod, reset springs are fixedly connected to both sides of the convex block, the other ends of the reset springs are fixedly connected with mounting seats, pressing shafts are fixedly connected to the upper ends of the mounting seats, brackets are bolted to one side of the mounting seats, and baffles are fixedly connected to one side of the brackets.

[0006] Specifically, two support frames are fixedly connected to the middle of the bottom plate. The two support frames are designed in a concave structure, and the concave openings of the support frames face downward.

[0007] Specifically, both ends of the oiling roller penetrate through the mounting frame and extend to the upper ends of the two support frames, and the outer walls of both ends are in contact with the upper surfaces of the support frames.

[0008] Specifically, one end of the extrusion frame is designed in an inclined structure. A reinforcing plate is fixedly connected at the angle between the inclined area and the straight area of the extrusion frame, and the thickness of the reinforcing plate is one-half of the thickness of the main body of the extrusion frame.

[0009] Specifically, the baffle is designed in a concave structure, and concave oil storage grooves are provided at the upper ends of the baffle. The center lines at both ends of the oiling roller correspond to the middle of the concave oil storage grooves.

[0010] Specifically, oil guide pipes are fixedly connected to one side of each baffle. The oil guide pipes are communicated with the concave oil storage grooves, and the other ends of the oil guide pipes are communicated with oil storage bottles. The bottom of the concave oil storage groove is inclined 5°-10° towards the two oil guide pipes.

[0011] Specifically, the oil guide pipes are made of oil-resistant rubber hoses, and an anti-static coating is provided on the inner side of the pipe walls.

[0012] Specifically, the fuel tank is in an inverted concave structure, and the inner wall is in close contact with the outer circumferential surface of the oiling roller.

[0013] Advantages of the present invention: Through the rigid linkage between the inclined surface of the extrusion frame and the extrusion shaft, when the oiling roller feeds towards the plate, the extrusion frame synchronously pushes the extrusion shaft to drive the baffle to close, realizing the synchronization of the oiling action and the blocking action. The baffle is in a concave structure, covering the edge of the drawing area, physically blocking the diffusion path of the lubricating oil to the free edge in terms of physical space, avoiding the situation of insufficient lubrication at the edge of the drawing area caused by excessive avoidance of the free edge and the free edge being contaminated with drawing oil due to excessive coating of the drawing area, saving the usage amount of the drawing oil, and effectively improving the precision and product quality of the oiling for the drawing forming of the automotive floor reinforcement plate.

Specific embodiments

[0017] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0018] As Figures 1-7 shown, the present invention provides the following technical solutions: Embodiment 1: A drawing forming device for an automotive floor reinforcement plate, including a bottom plate 1, an oiling mechanism for drawing forming is arranged on one side of the bottom plate 1, and a shielding mechanism for shielding the free edge is arranged on the other side of the bottom plate 1; The oiling mechanism includes an electric telescopic rod 2 fixedly installed on one side of the bottom plate 1, the output end of the electric telescopic rod 2 is fixedly connected with a mounting frame 3, the upper end of the mounting frame 3 is fixedly connected with a fuel tank 4, the mounting frame 3 is rotatably connected with an oiling roller 5 corresponding to the fuel tank 4, and an extrusion frame 6 is fixedly connected to one side of the fuel tank 4; The shielding mechanism includes a guide rod 7 fixedly connected to the upper end of one side of the bottom plate 1, a convex block 8 is fixedly connected to the middle of the guide rod 7, return springs 9 are fixedly connected to both sides of the convex block 8, the other ends of the return springs 9 are fixedly connected with mounting seats 10, extrusion shafts 11 are fixedly connected to the upper ends of the mounting seats 10, brackets 12 are bolted to one side of the mounting seats 10, and baffles 13 are fixedly connected to one side of the brackets 12; One end of the extrusion frame 6 is designed with an inclined structure, a reinforcement plate 15 is fixedly connected at the angle between the inclined area and the straight area of the extrusion frame 6, and the thickness of the reinforcement plate 15 is one-half of the main thickness of the extrusion frame 6; The baffle 13 is designed with a concave structure, concave oil storage grooves 16 are opened at the upper ends of the baffles 13, and the center lines at both ends of the oiling roller 5 correspond to the middle of the concave oil storage grooves 16; Oil guide pipes 17 are fixedly connected to one side of the baffles 13, the oil guide pipes 17 are communicated with the concave oil storage grooves 16, the other ends of the oil guide pipes 17 are communicated with oil storage bottles 18, and the bottom of the concave oil storage grooves 16 is inclined 5° - 10° towards both sides of the oil guide pipes 17.

[0019] During use, place the automotive floor reinforcement plate to be processed on the bottom plate, start the electric telescopic rod 2, and its output end drives the fuel tank 4 and the oiling roller 5 to move towards the plate through the mounting bracket 3. During this process, the inclined area of the extrusion frame 6 first contacts the extrusion shaft 11. As the electric telescopic rod 2 advances, the inclined surface gradually squeezes the extrusion shaft 11, forcing the two mounting seats 10 to slide towards the middle along the guide rod 7, and the return spring 9 is compressed, storing elastic potential energy. The mounting seat 10 drives the baffle 13 to move synchronously through the bracket 12 until the two baffles 13 fit together, completely blocking the free edge area of the plate. When the flat area of the extrusion frame 6 is in full contact with the extrusion shaft 11, the electric telescopic rod 2 stops moving, and the oiling roller 5 fits with the drawing area of the plate. The oiling roller 5 moves under the drive of the mounting bracket 3, dips lubricating oil from the fuel tank 4 and evenly coats it on the drawing and forming area of the plate; The inclined design of the extrusion frame 6 ensures that during the sliding process of the extrusion shaft 11, the baffle 13 is synchronously adjusted to the optimal shielding position to prevent the free edge from being oiled. The grease dripping from both ends of the oiling roller 5 directly falls into the concave oil storage groove 16 at the upper end of the baffle 13 and flows into the oil guide pipe 17 along the inclined bottom of the groove at an angle of 5 to 10 degrees, and finally is collected into the oil storage bottle 18. After the oiling operation is completed, the electric telescopic rod 2 contracts in the reverse direction, driving the extrusion frame 6 to disengage from the extrusion shaft 11. The return spring 9 releases the elastic potential energy, pushing the mounting seat 10 to reset along the guide rod 7, and the baffle 13 separates, facilitating the removal of the plate.

[0020] Embodiment 2: The technical solutions of this embodiment different from those of Embodiment 1 include: Two support frames 14 are fixedly connected to the middle of the bottom plate 1. The two support frames 14 are designed with a concave structure, and the concave opening of the support frame 14 faces downward. Both ends of the oiling roller 5 penetrate through the mounting bracket 3 and extend to the upper ends of the two support frames 14, and the outer walls of both ends are in contact with the upper surface of the support frame 14. The oil guide pipe 17 is an oil-resistant rubber pipe, and an anti-static coating is provided on the inner side of the pipe wall. The connection port of the oil guide pipe 17 with the concave oil storage groove 16 is located at the lowest point of the concave oil storage groove 16. The inner wall coating of the oil guide pipe 17 prevents impurities from being adsorbed by the grease due to static electricity. The connection port is located at the lowest point of the oil storage groove 16, and a transparent observation window is provided on the bottle body. The fuel tank 4 has an inverted concave structure, and the inner wall is in close contact with the outer circumferential surface of the oiling roller 5.

[0021] During use, both ends of the oiling roller 5 extend to the upper ends of the support frames 14, and the outer walls are in contact with the upper surface of the support frame, forming a simply supported beam structure supported at both ends. During the movement of the oiling roller 5, the support frame 14 can bear the weight of the oiling roller 5, significantly reducing the vertical load and bending moment of the electric telescopic rod 2. The connection port located at the lowest point of the oil storage groove 16 can ensure that the grease is exported without residue. During the process of collecting the drawing oil, the transparent observation window of the oil storage bottle 18 can monitor the oil volume in real time. The close contact between the inner wall of the fuel tank 4 and the outer circumferential surface of the oiling roller 5 can prevent the drawing oil from leaking out.
