Description

Sheet metal rotation punch die

Technical field

The utility model relates to a kind of punch die, especially sheet metal is rotated the punch die of punching processing.

Background technology

Producer, in the time manufacturing electrical equipment, household electrical appliances, building and ornament materials, regulator cubicle, cooking apparatus etc. Related product, need to carry out punching processing to sheet metal, to meet ventilation, printing opacity, control volume, object attractive in appearance. Under normal circumstances, the thickness of sheet metal is 2 millimeter, and the lathe that carries out punching processing is punch press. Punch press is mainly made up of parts such as actuating unit, deceleration and drive mechanism, slide block, guide rail, workbench. Although numerical control press can greatly improve service efficiency and the machining accuracy of pressing equipment, there is machine automated programming on whole plate, automatic location, automatic discharge, automatic press function, but numerical control press is expensive, maintenance cost and manipulation technical requirement are high, and therefore most of small-sized manufacturing firms adopt common punch press to carry out the punching processing of sheet metal more now. This related die that just need to use on punch press is punch die. For attractive in appearance, the shape of single punching can be rectangle, circle, triangle, rhombus etc., and the distribution of multiple punching on sheet metal also can be designed to multiple layout, as parallel, circular, star etc. In the time that being become to the pattern distributing around the center of circle, punching processing just need to rotate punch die.

No. CN101569905A disclosed " rotating punching device " patent (application number: 200910085790.7) of Chinese patent, comprise driven gear, Passive Positioning roller, driving gear, positive location roller, die roller, die, drift, stamping die roller, stamping die roller and die roller are by driving gear and the intermeshing synchronous rotary of realizing of driven gear, make the die on drift and the die roller on stamping die roller be engaged in punching on sheet material, driving gear drives rotation by driving shaft; Drift and die are provided with the phase adjusting apparatus that comprises positive location roller, Passive Positioning roller, bulb alignment pin, die roller, stamping die roller, for realizing axial phase place adjustment and the circumferentially phase place adjustment of described drift and described die. The weak point of this patent is: stamping die roller and die roller, by driving gear and the intermeshing synchronous rotary of realizing of driven gear, can be rotated punching processing, but makes punch press and punch die structure become quite complicated.

No. CN201537655U disclosed " metal plate punching device " patent (application number: 200920210804.9) of Chinese patent, comprise patrix and the counterdie of being located at below, patrix comprises punch die, fixed head, buck plate, punch die upper end is fixed on fixed head, and fixed head is located at buck plate bottom; Counterdie comprises die and base, and base is provided with boss, and die is located on boss, and with boss threaded engagement; The shearing force that upper and lower motion by punch die and punch die and die form, can be on sheet metal fast punching go out to meet the circular hole of GB/T15825.4-2008 standard. The weak point of this patent is: die adopts the mode of screw thread rotation to be connected with boss, can regulate easily the height of die, but cannot be rotated punching processing.
