Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to an in-mold oil adding structure for a hardware stamping die. Background Technique

[0002] Hardware stamping is a common metal processing technology, which is widely used in industries such as automobiles, household appliances, and communication equipment. It stamps metal sheets into required shapes through dies, with the advantages of high efficiency, high precision, and low cost.

[0003] The main functions of in-mold oil adding for hardware stamping dies are lubrication, cooling, rust prevention, cleaning, buffering, noise reduction, anti-adhesion, and environmental protection.

[0004] There are mainly two existing ways to add oil to stamping copper materials. One is to drip oil onto the copper material at the feeding port. The disadvantages of this method are that there is oil on the entire stamping material, resulting in waste of cutting oil. In addition, in the second half of stamping, due to the volatilization and vaporization of the oil, there is no oil in the second half, which will affect the punching life of the die. The other is to spray oil into the die cavity. The disadvantages of this method are that first, there is waste of cutting oil, and second, the sprayed oil mist will also pollute the environment. Therefore, a new solution is needed to solve this problem. Content of the Utility Model

An upper die clamping plate is arranged at the lower end of the upper die backing plate. The punch is installed on the upper die clamping plate. A push plate backing plate is arranged between the upper die clamping plate and the stripper plate.

[0008] Further, a lower die base is arranged below the upper die base. A lower template is arranged above the lower die base. A lower die backing plate is arranged between the lower die base and the lower template. Guide columns are arranged between the upper die base and the lower die base.

[0009] Further, a fixing frame is installed on the lower die base. A first roller is rotatably installed on the fixing frame. A second roller is arranged above the first roller. The second roller is rotatably installed on the fixing frame through a slider. The first roller and the second roller are arranged in parallel.

[0010] Further, a screw rod is rotatably installed on the fixing frame. One end of the screw rod is rotatably installed on the fixing frame, and the other end of the screw rod is in threaded connection with the slider. The slider is slidably arranged on the fixing frame.

[0011] Further, an adjusting rod is arranged on one side of the screw rod. The adjusting rod is rotatably installed on the fixing frame. Bevel gears are installed on both the screw rod and the adjusting rod. The bevel gear on the screw rod is in meshing transmission with the bevel gear on the adjusting rod.

[0012] Further, a guiding groove is arranged on the fixing frame. The slider is slidably arranged in the guiding groove. The screw rod is arranged inside the guiding groove.

[0014] 1. By providing components such as an oil delivery groove, a connector, and a stripping plate, in the working process, through the mutual cooperation between the connector component and the oil delivery groove, the connector is installed on the side of the die stripping plate, and an oil delivery groove is added to the stripping plate. The connector is communicated with the oil delivery groove, so that oil can be delivered to the working position that needs to be lubricated, avoiding the waste of overall lubrication and the situation of no oil due to volatilization in the second half, and reducing the pollution of the cutting oil to the environment.

[0015] 2. By providing components such as an adjusting rod, a screw rod, bevel gears, and a slider, in the working process, through the mutual cooperation between the adjusting rod component, the bevel gear component and the screw rod component, by driving the adjusting rod component to rotate by personnel, the slider is driven to slide on the fixing frame. When the slider moves, the second roller is driven to move accordingly, so that the position between the first roller and the second roller is adjusted, and workpieces of different heights can be limited, improving the stability of the workpiece during processing.
