A trimming method and device for a punched piece of a cosmetic foundation cover

Abstract

The invention discloses a trimming method for a punched part of a cosmetic foundation cover. First, a thin aluminum material which is 0.5-2mm in thickness is punched to make a foundation cover workpiece. Then, the foundation cover workpiece of which the cut surface has burrs is clamped on a lathe. Secondary machining is carried out on the cut surface of the cosmetic foundation cover workpiece by using a tuning tool, enabling the cut surface to be smooth and burr-free. The invention further discloses a trimming device. The trimming device comprises a base and a vertical column, wherein a working table is mounted on the vertical column, a die and a tool rest are arranged on the working table, the die is mounted on the working table through a rotating mechanism, the tool rest is arranged at one side of the die, a turning tool is clamped on the tool rest, a spinning mechanism and a driving handle which is connected with the spinning mechanism and drives the spinning mechanism to move up and down are mounted at the top end of the vertical column, and the spinning mechanism is arranged above the die. The method is feasible and effective. The device is simple in structure, convenient to operate, low in labor intensity and high in production efficiency and is more favorable to improving the machining quality of the foundation cover and reducing production cost.

Description

【Technical field】 [0001] The invention relates to a mechanical processing method and a device, in particular to a method and a device for trimming a blanked piece of a cosmetic foundation cover. 【Background technique】 [0002] Thin-plate aluminum materials with a thickness of 0.5 mm to 2 mm are prone to problems such as uneven cutting surface and many burrs during punching. In order to improve the processing quality of workpieces of this type of material, the current method is to use reasonable mold clearance, Keep the cutting edge of the mold sharp, use pressure plate, top plate or use paper covering method and other measures. These methods can well control the processing quality of the workpiece, but the method is complicated and the production cost is high, so it is not suitable for the foundation cover blanking parts that do not require high dimensional accuracy. 【Content of invention】 [0003] The purpose of the present invention is to overcome the shortcomings and d...

Problems solved by technology

[0002] Thin-plate aluminum materials with a thickness of 0.5 mm to 2 mm are prone to problems such as uneven cutting surface and many burrs during punching. In order to improve the processing quality of workpieces of this type of material, the current method is to use reasonable mold clearance, Keep the cutting edge of the mold sharp, adopt pressure plate, top plate or use paper covering method and other measures

These methods can control the processing quality of the workpiece very well, but the method is complicated and the production cost is high, so it is not suitable for the foundation cover blanking parts that do not require high dimensional accuracy.
