Bolt hole machining device for die machining

Abstract

The invention discloses a bolt hole machining device for die machining. The bolt hole machining device comprises a clamping motor, a left clamping jaw, a right clamping jaw, a main driving motor, a lifting frame and a drilling motor, wherein a main support is arranged on the upper surface of a platform, the clamping motor is fixedly installed on the right side of the main support, the left end ofthe output shaft of the clamping motor is fixedly provided with a ball screw through a coupler, a left sliding block and a right sliding block are installed on the left portion and the right portion of a ball screw in a threaded mode, and the left clamping jaw and the right clamping jaw are fixedly arranged on the upper side of the left sliding block and the upper side of the right sliding block through screws respectively. The right sliding block is novel in structure, the distance between the left sliding block and the right sliding block is adjusted, the clamping work of molds with different specifications can be met, the universality of the device is greatly improved, and the mold does not need to be replaced during machining; and through the cooperation of a half gear and a sliding rack, a drill bit can move up and down continuously, and compared with a one-time drilling mode, the drill bit can be effectively protected in a continuous pressurization and continuous drilling mode, and the fracture risk of the drill bit is reduced.

Description

technical field [0001] The invention relates to the field of motors, in particular to a bolt hole processing device for mold machining. Background technique [0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Under the action of external force, the blank becomes a tool with a specific shape and size. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a spec...

Problems solved by technology

[0003] In the mold processing process, it is often necessary to process the bolt holes of the mold. In the bolt hole processing process of the existing mold, different clamping tasks need to be exchanged for molds of different specifications during processing, and the existing devices are not used during processing. It is often the case that the drill bit is fed too fast and the drill bit breaks
