Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tool processing, and more specifically to a side punching spring rigid material pressing mechanism. Background Art

[0002] Side punching, as the name implies, refers to the punching operation on the side of the workpiece to form the desired hole. This process is widely used in electronics, communications, home appliances, automobiles and other industries.

[0003] After searching, the Chinese authorized utility model patent with announcement number CN209886472U discloses a double-wedge side punching tooling for CNC lathe parts, which has the advantages of simple structure and easy operation. The double-wedge design improves the coaxiality of the auxiliary mold tooling when punching the product, thereby improving the product quality.

[0004] At present, the common disadvantages of the above-mentioned side punching mold are: the inclined wedge mechanism converts the vertical impact force into a horizontal impact force, so that the punching punch can punch the workpiece from the outside to the inside, but burrs will be generated at the impact edge of the workpiece, and the burrs obtained by this production method will be located on the inner side of the workpiece hole body. Subsequently, the burrs on the inner wall of the workpiece at the punching position need to be polished and removed. This existing production method increases the production process of the product and the work intensity of the personnel, and the effect of burr removal is difficult to guarantee, resulting in the production quality of the product and customer satisfaction being affected.

The cylinder 7, the extrusion ramp guide rails and the pressing assembly 8 are public technologies in the comparative documents, and their installation and working methods are not repeated here. After the workpiece 6 is punched by the side of the pressing assembly 8, a burr hole 601 is formed on the side wall. An assembly hole 501 is provided at the inner end of the bottom die 5, and the assembly hole 501 is arranged parallel to the pressing assembly 8. A mounting seat 9 is fixedly connected to the middle of the inner end of the assembly hole 501, and a double-acting cylinder 10 is installed on the mounting seat 9. Both output ends of the double-acting cylinder 10 are fixedly connected to a drive shaft 11, and one end of the drive shaft 11 away from the double-acting cylinder 10 is fixedly connected to a grinding column 12, and the grinding column 12 is made of high-speed steel.

[0028] See also Figure 3-4The inner end of the bottom mold 5 is provided with a limiting groove 502 connected to the assembly hole 501, and the limiting groove 502 is located on the side of the assembly hole 501. The side wall of the grinding column 12 is fixedly connected to the limiting slider 13, and the limiting slider 13 is located in the limiting groove 502 and is slidably connected thereto. The assembly hole 501 is an annular hole, and the grinding column 12 is a cylinder matching the shape of the assembly hole 501.
