Abstract
The utility model relates to a stamping device comprising a needle plate (1) and a pressing plate (3), wherein the needle plate (1) is provided with needles, the pressing plate (3) is arranged between the needle plate (1) and a plate material, and through holes corresponding to the needles on the needle plate (1) are arranged in the pressing plate (3). Sound absorption of the plate material stamped by the stamping device is greatly improved, flatness of the plate is improved, and the plate is not prone to being broken.
Description
Technical field
The utility model relates to a kind of decompressor, relates in particular to a kind of decompressor for mineral wool board.
Background technology
In the production process of mineral wool board, existing decompressor is that the embossing degree of depth is more shallow, so that the sound absorbing capabilities of mineral wool board on low frequency is very poor with the roller of a lot of projections.And roller self is heavier, and after the punching press, the flatness of sheet material is difficult for keeping, and sheet material ruptures easily.
The utility model content
Technical problem to be solved in the utility model is the embossing degree of depth that increases sheet material after the punching press, improve sheet material on low frequency sound absorbing capabilities and keep the flatness of sheet material.
In order to solve the problems of the technologies described above, the utility model provides a kind of decompressor, comprises the needle plate and the pressing plate that are provided with pin, and pressing plate is arranged between needle plate and the sheet material, and pressing plate is provided with the through hole corresponding with the pin of needle plate.
The density of pin on needle plate can be set to 7000-20000 pin/m
2
Decompressor can also comprise push rod, and push rod is arranged on the pressing plate, and push rod can be elastic device.
Push rod can be cam or spring.
Decompressor provided by the utility model, solved the embossing degree of depth and crossed the problem that dark rear decompressor is not easy to lift from sheet material, the degree of depth of the sheet material internal holes that it stamps out is increased to about 15mm from about 4mm, so that the sound absorption of sheet material improves greatly, show that noise reduction coefficient (NRC) has improved about 0.1, improved simultaneously the flatness of plate, and plate easy fracture not.
Description of drawings
Fig. 1 is the schematic diagram according to decompressor of the present utility model.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, hereinafter in connection with accompanying drawing embodiment of the present utility model is elaborated.
Referring to Fig. 1, Fig. 1 shows the schematic diagram according to decompressor of the present utility model.This decompressor comprises needle plate 1, push rod 2 and pressing plate 3, and pressing plate 3 is arranged between needle plate 1 and the mineral wool board 4, and push rod 2 is arranged on the pressing plate 3.Needle plate 1 is provided with for the pin to mineral wool board 4 punching presses, and pin is made by hard and wear-resisting material.Preferably, the density of setting of pin on needle plate 1 is 7000-20000 pin/m
2Pressing plate 3 is provided with the through hole corresponding with the pin on the needle plate 1.
Aborning, mineral wool board 4 is placed on the conveying roller 5, and mineral wool board 4 is driven by the conveying roller 5 that runs up and advances at utmost speed.During punching press, needle plate 1 props up push rod 2, and the pin on the needle plate 1 passes the through hole on the pressing plate 3 simultaneously, and needle plate and pressing plate move downward simultaneously, and to the mineral wool board punching, preferably, the thickness of pressing plate can arrange as required, and also thorn stings mineral wool board thoroughly or not alternatively.After punching press was complete, needle plate 1 returned under the effect of push rod 2, and then pressing plate lifts, and finished the process of a punching press.In the process of punching press, push rod 2 works to withstand needle plate 1 and makes its resilience.Push rod 2 is elastic device, is preferably cam and spring.
Employing is according to decompressor of the present utility model, solved the embossing degree of depth and crossed the problem that dark rear decompressor is not easy to lift from sheet material, the degree of depth in the intralamellar part hole that extrudes is increased to about 15mm from about 4mm, so that the sound absorption of sheet material improves greatly, show that noise reduction coefficient (NRC) has improved about 0.1, improved simultaneously the flatness of plate, and plate easy fracture not.
Although the disclosed embodiment of the utility model as above, the embodiment that described content just adopts for the ease of understanding the utility model is not to limit the utility model.Technical staff under any the utility model in the technical field; under the prerequisite that does not break away from the disclosed spirit and scope of the utility model; can do any modification and variation in the details that reaches of implementing in form; but scope of patent protection of the present utility model still must be as the criterion with the scope that appending claims was defined.
