CNC punch array die installation structure

Abstract

The invention relates to an array type die installation structure of a numerical control press. The array type die installation structure of the numerical control press comprises a punch, a die replacing structure, an upper die plate, a lower die plate, an upper die assembly and a lower die assembly, wherein the upper die assembly is installed on the upper die plate in a sleeving connecting mode; the lower die assembly is fixedly installed in the lower die plate; and the upper die assembly corresponds to the upper die assembly in position. The array type die installation structure of the numerical control press is characterized in that the punch is located above the upper die plate correspondingly and corresponds to the upper die assembly in position; the die replacing structure is composed of a telescopic driving assembly, an installation seat, a connector and a piston, the installation seat is fixedly installed on the upper die plate, the telescopic driving assembly is installed on one side of the upper die plate, is connected with one end of the connector and pushes the connector to move, and the piston is installed at the other end of the connector, is in sliding connection with the connector, and corresponds to the upper die assembly in position. The array type die installation structure of the numerical control press is simple, low in punching energy consumption and high in punching frequency, and the die replacing structure is long in service life.

Description

technical field [0001] The invention relates to parts of a numerical control punching machine, in particular to an array mold installation structure of a numerical control punching machine. Background technique [0002] CNC punching machine is the abbreviation of digital control punching machine, which is an automatic machine tool equipped with a program control system. The control system can logically process and decode programs with control codes or other symbolic instructions, so as to make the punch press move and process parts. [0003] The CNC punching machine can be used for processing various types of metal sheet parts, and can automatically complete a variety of complex hole types and shallow stretch forming processing at one time. The punching method punches large round holes, square holes, waist-shaped holes and various shapes of curved contours, and can also be processed by special processes, such as shutters, shallow stretching, countersinking, flanging holes, ...

Problems solved by technology

[0004] Chinese patent CN201520009553.3, titled "Numerical Control Punch", discloses a technical solution for a CNC punch. The CNC punch proposed in this solution completes the processing by high-speed and long-term continuous punching of the punch, and the mold change structure It is installed on the punch that is punched frequently, so the die changing structure also moves up and down following the punch. The weight of the punch itself plus the weight of the die changing structure will cause great energy consumption to the CNC punching machine; the die changing structure follows The punch moves up and down frequently, and when the punch hits downwards at high speed and frequently, it will generate frequent vibrations of more than 20 tons. Since the die change structure is composed of multiple moving parts, intense and frequent vibrations will inevitably lead to damage to the connecting parts, derailment and eventually lead to replacement. If the mold fails, the telescopic drive components and the trachea will also be damaged due to frequent up and down movements and vibrations, and the trachea will be strained and leaked, etc.

The above technical shortcomings have seriously affected the working efficiency of the punch press, stamping energy consumption and the service life of the die change structure.
