Description
Technical field
The present invention relates to perforating die technical field of mold, be specially a kind of deafener flat holder perforating die.
Background technology
Deafener is to stop sound transmission and a kind of device of allowing air-flow to pass through, is the important measures eliminating air power noise.Deafener is mounted in air powered equipment (such as aerator, air compressor machine, boiler exhaust mouth, electromotor, the equipment that the air vent noises such as water pump are bigger) gas channel on or enter, the device reducing noise in gas extraction system, the kind of deafener is a lot, but study carefully its noise elimination mechanism, they can be divided into six kinds of main types again, i.e. resistive muffler, resistant noise-reducing device, impedance complex formula deafener, microperforated panel deafener, aperture deafener and active deafener, the selection of deafener should be according to fire prevention, moistureproof, anticorrosion, purity requirements, the locus installed, noise source spectral characteristic, system natural phonation is decayed, system airflow regenerated noise, room noice control, correlations press drop, the variant factors such as equipment price consider and have laid particular stress on according to practical situation.In deafener production process, need the flat holder of deafener is punched out processing, but current perforating die, it is impossible to well complete the punch work in multiple hole, therefore devise a kind of deafener flat holder perforating die.
Summary of the invention
For problem above, the invention provides a kind of deafener flat holder perforating die, the punch work in multiple hole can be completed simultaneously, substantially increase the production efficiency of flat holder so that the effect of deafener is more outstanding, is worthy to be popularized.
For achieving the above object, the present invention provides following technical scheme: a kind of deafener flat holder perforating die, including upper bolster, die shoe and punching pin, described upper bolster is arranged on die shoe upper end, described upper bolster upper end is provided with driving motor, described upper bolster lower end is provided with upper mounted plate, fixed plate lower end is provided with loading and unloading material plate, described punching pin is arranged on loading and unloading material plate lower end, described punching pin is provided with three, it is provided with limiting plate below described punching pin, described limiting plate is fixed on loading and unloading material plate by fixing bar, punching pin outlet it is provided with on described limiting plate, it is provided with support bar between described upper bolster and die shoe, described die shoe upper end is provided with lower bolster, described lower bolster upper end is provided with die block.
As a kind of preferably technical scheme of the present invention, described die shoe lower end is provided with damping device, and described damping device lower end is provided with rubber blanket.
As a kind of preferably technical scheme of the present invention, outside described fixing bar, it is provided with little retracting spring.
As a kind of preferably technical scheme of the present invention, outside described support bar, it is provided with big retracting spring.
As a kind of preferably technical scheme of the present invention, described die block includes plate body, and described plate body is provided with groove, and described groove is provided above three punchings, and described plate body is provided with four installing holes.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is by die holder setting up and down, can well fix punching pin, utilize multiple punching pin, the Cheng Mo of multiple punching of same time can be completed, limiting plate is utilized to limit the degree of depth of punching, whole apparatus structure is compact, and design principle is simple, has good use value, the punch work in multiple hole can be completed simultaneously, substantially increase the production efficiency of flat holder so that the effect of deafener is more outstanding, is worthy to be popularized.
