Description

Technical Field

[0001] This utility model belongs to the field of sheet metal trimming technology, specifically relating to a lubrication device for a vehicle sheet metal trimming mold and the trimming mold itself. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube and profile materials, causing them to undergo plastic deformation or separation, thereby obtaining workpieces (stamped parts) of the required shape and size.

[0003] A sheet metal stamping machine with lubrication function, patent number CN201922049152.1, includes a frame, a worktable, an oil storage box, a lubrication roller, a square box, and an oil drip hole. By rotating the lubrication roller, the lubricating oil in the oil storage box is coated onto the steel strip, reducing friction during the stamping process. However, although this lubrication method can reduce friction during the stamping and cutting process, since this lubrication is applied by a roller, firstly, local missed coating is likely to occur during the coating process; secondly, since the stamping and cutting process only involves local actions, the method of comprehensive coating results in the waste of lubricating oil and also increases the workload of subsequent surface cleaning of parts.

[0015] like Figures 1 to 6As shown, this utility model provides a technical solution: a lubrication device for a vehicle sheet metal trimming mold and the trimming mold itself, including a mounting base 1 for placing vehicle sheet metal. A trimming punch 2 is mounted above the mounting base 1. A cutting oil passage 3 is installed inside the trimming punch 2 near the mounting base 1. The cutting oil passage 3 includes multiple sets of oil outlets arranged along the cutting edge of the trimming punch 2. A punch oil passage 4 is mounted on the top of the trimming punch 2, and the punch oil passage 4 includes at least one set of oil leakage outlets. The oil drain is located on the side of the inner hole punch. The oil inlet ends of the cutting oil passage 3 and the punch oil passage 4 are both connected to an external oil box. By installing the cutting oil passage 3 and the punch oil passage 4 in the cutting punch part 2, the cutting oil passage 3 is used to apply lubricating oil to the sheet metal cutting area, and the punch oil passage 4 is used to apply lubricating oil to the vicinity of the inner hole punch. This reduces friction during the cutting process of sheet metal, and by applying lubricating oil to the area to be cut of the sheet metal, the waste of lubricating oil is reduced, and the entire sheet metal surface is prevented from being covered with lubricating oil, thus reducing the cleaning time of the lubricating oil on the sheet metal surface afterward.

[0016] In a further embodiment, such as Figure 3 As shown, the cut oil passage 3 includes two sets of X-axis cut oil inlet pipes 31, which are arranged opposite each other at the edge of the cut-edge punched part 2. The oil inlet end of the cut-edge oil inlet pipe is connected to the oil pipe of the connecting oil box through a straight pipe joint. Two sets of Y-axis cut oil inlet pipes 32 are installed between the X-axis cut oil inlet pipes 31. The Y-axis cut oil inlet pipes 32 are arranged perpendicular to the X-axis cut oil inlet pipes 31. The two ends of the Y-axis cut oil inlet pipes 32 are respectively connected to each set of X-axis cut oil inlet pipes 31. Several cut-edge oil outlet pipes 33 are provided below the X-axis cut oil inlet pipes 31 and the Y-axis cut oil inlet pipes 32. The X-axis cut-in oil pipe 31 or the Y-axis cut-in oil pipe 32 is vertically connected. The cut-out oil pipe 33 is embedded in the edge of the cut-out punch 2. The lubricating oil discharged from the cut-out oil pipe 33 coats the cut-out punch 2 at the position of the sheet metal cut-out edge. Through the cooperation of the straight pipe and the oil pipe, the lubricating oil in the oil box is transported to the X-axis cut-in oil pipe 31 and the Y-axis cut-in oil pipe 32. The cut-out oil pipe 33 installed below the X-axis cut-in oil pipe 31 and the Y-axis cut-in oil pipe 32 smoothly coats the lubricating oil at the predetermined position of the sheet metal, waiting for the cut-out process. This allows for precise coating of lubricating oil, reduces lubricating oil waste, and reduces friction during the cut-out process.

[0017] In a further embodiment, such as Figure 3As shown, the punch oil circuit 4 includes an X-axis punch oil inlet pipe 41. The oil inlet end of the X-axis punch oil inlet pipe 41 is connected to the oil pipe of the oil box through a straight pipe connector. A Y-axis punch oil inlet pipe 42 is connected to the X-axis punch oil inlet pipe 41. The Y-axis punch oil inlet pipe 42 is located above the inner hole punch. The same number of punch oil outlet pipes 43 as the inner hole punches are installed below the Y-axis punch oil inlet pipe 42. The punch oil outlet pipes 43 are located on the side of the inner hole punches. The lubricating oil discharged from the punch oil outlet pipes 43 coats the position of the inner hole punch 82 where it is to be punched in the sheet metal. That is, with the cooperation of the straight pipe connector and the oil pipe, the lubricating oil in the oil box flows smoothly to the punch oil outlet pipes 43. By coating the sheet metal with lubricating oil through the punch oil outlet pipes 43, the friction between the punch and the sheet metal during the punching process can be reduced.

[0018] A vehicle sheet metal trimming mold includes a lower mounting bracket 5, on which a support assembly 6 is mounted. The top surface of the support assembly 6 is used to place the sheet metal to be processed. An upper mounting bracket 7 is inserted into the lower mounting bracket 5, forming a receiving space between the lower mounting bracket 5 and the upper mounting bracket 7. A trimming punch 2 is mounted on the end face of the upper mounting bracket 7 near the lower mounting bracket 5. A lubrication assembly 8 is installed inside the trimming punch 2. The lubrication assembly 8 is a lubrication device for a vehicle sheet metal trimming mold as described above. The support assembly 6 is used to move the sheet metal to be processed closer to or away from the trimming punch 2. The trimming punch 2 is used for trimming or punching the sheet metal to be processed. The support assembly 6 includes at least two sets of small extensions. In this embodiment, three sets of small telescopic rods 61 are used. Each set of small telescopic rods 61 is installed in the lower mounting frame 5. The moving end of the small telescopic rod 61 passes through the top surface of the lower mounting frame 5. A placement plate is installed on the top surface of the lower mounting frame 5. The end face of the placement plate near the lower mounting frame 5 is connected to the moving end of the small telescopic rod 61. Several grooves 62 are formed on the end face of the placement plate away from the small telescopic rod 61. The grooves 62 correspond one-to-one with the protrusions of the sheet metal to be processed. Under the action of the small telescopic rods 61, the placement plate moves back and forth along the axial direction of the small telescopic rods 61, that is, it drives the sheet metal to be processed to move closer to or away from the cutting and punching part 2 for cutting or punching.

[0019] In a further embodiment, the placement plate includes a plurality of placement blocks 63, which are mounted on the top surface of the lower mounting bracket 5 via connectors. The groove 62 is formed on the top surface of the placement blocks 63. That is, the placement blocks 63 are spliced ​​together to form a placement plate. This allows for the splicing of matching placement plates when cutting and punching sheet metal of different shapes, thereby reducing the manufacturing cost of the placement plate.

[0020] In a further embodiment, the edge-cutting punch 2 includes a mounting plate, which is mounted on the end of the upper mounting bracket 7 near the lower mounting bracket 5. A gap is reserved between the mounting plate and the upper mounting bracket 7, and the punch oil passage 4 is located within the gap. At least one set of inner hole punches is mounted longitudinally inside the mounting plate. In this embodiment, two sets of inner hole punches are used. The oil outlet of the punch oil passage 4 is close to the inner hole punch. That is, the punch oil passage 4 applies lubricating oil to the sheet metal at the corresponding position of the inner hole punch, thereby reducing the friction of the inner hole punch when punching the sheet metal. An edge-cutting blade assembly is mounted on the end of the mounting plate near the lower mounting bracket 5. Several oil outlet columns are opened longitudinally along the edge of the edge-cutting blade assembly. The edge-cutting oil outlet of the cutting oil passage 3 is inserted into the oil outlet columns. By utilizing the cooperation between the edge-cutting oil outlet and the oil outlet columns, lubricating oil is applied to the position of the sheet metal to be cut, thereby reducing the friction of the edge-cutting blade assembly on the sheet metal when cutting the edge.

[0021] Through the above technical solution, the present invention can achieve the following working process: A small telescopic rod 61 is used to move the sheet metal closer to the cutting and punching part 2. After the sheet metal approaches the cutting and punching part 2, lubricating oil is applied to the predetermined position of the sheet metal with the cooperation of the cutting oil passage 3 and the punch oil passage 4. Driven by the power source, the cutting and punching part 2 is driven to cut and punch the sheet metal. This reduces friction during the cutting process and reduces lubricating oil waste by applying lubricating oil only to the area to be cut, avoiding the need to cover the entire sheet metal surface with lubricating oil and reducing the subsequent cleaning time of the lubricating oil on the sheet metal surface. The preferred embodiment of this utility model has been described in detail above. However, this utility model is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this utility model, various equivalent transformations can be made to the technical solution of this utility model, and these equivalent transformations all fall within the protection scope of this utility model.
