Description

Structure for densely punching brass plate

Technical Field

The utility model relates to a curtain board technical field specifically is a structure that is used for the brass board intensive punching a hole.

Background

The curtain wall board has unique texture, rich and durable color and luster, and diversified appearance and shape, can be perfectly combined with glass curtain wall materials and stone curtain wall materials, has perfect appearance and excellent quality, and is favored by owners.

The curtain wall board is attractive in appearance and light in weight, dense holes can be formed in the curtain wall board, the load of the wall surface is reduced, the dense holes can also play a role in absorbing noise, the thickness of the curtain wall board made of brass reaches 3mm, the punching distance is small, and the traditional process is low in efficiency and easy to damage due to repeated impact due to the fact that a single punching hole is formed in the traditional process.

The prior art can not realize the intensive punching of the brass plate with the thickness of less than 3 mm.

Based on this, the utility model designs a structure that is used for the brass board to closely punch a hole to solve above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a structure that is used for the brass board to closely punch a hole to the prior art who proposes in solving above-mentioned background art can't realize carrying out the problem that closely punches a hole to the brass board below the thickness 3 mm.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a structure for brass plate intensive punching, is including installing the mould on numerical control punch press, and rectangular array has the multiunit to be used for carrying out the punching needle that intensive punching was punched to the brass plate below 3mm thickness on the mould, it is the cylinder of diameter 3.0mm to punch the needle, two liang of adjacent it is 9.7mm to punch the interval between the needle center pin.

Preferably, the punching needle is made of steel.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a multiunit of rectangle array is punched the needle and is realized intensive punching a hole, has improved punching efficiency, avoids punching the damage of needle and brass board, and intensive hole noise absorbing capacity is better.

Fig. 2 is the structural schematic diagram of the intensive punching on the brass plate of the present invention.

In the drawings, the components represented by the respective reference numerals are listed below:

2. and (5) punching the needle.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Example 1: the method comprises the steps of carrying out dense punching on a brass plate with the length of 4.5m and the thickness of 3.0mm, and adopting a cylindrical punching needle 2 square array with the diameter of 3mm on a die in order to punch dense holes with the diameter of 3mm and the central shaft distance b between every two adjacent holes on the brass plate =4.85, wherein the array number is 20 x 20, the central shaft distance a between every two adjacent punching needles 2 is 9.7mm, and a =2 x b.

The brass plate to be punched is placed on a numerical control punching machine, the numerical control punching machine punches the brass through the punching needles 2 arrayed on the die, at the moment, the distance between every two adjacent holes on the brass plate is a, and the numerical control punching machine drives the die to move for 0.5 x a along two directions of the punching needle 2 array in sequence to punch the brass plate again, so that the distance between every two adjacent holes on the brass plate is b.

The area that multiunit punching needle 2 formed on the mould is less than the area of brass board far away, punches a hole through punching needle 2 of array on the mould at the different positions of brass board and forms intensive hole, then converts the hole of mending of whole space of a whole page into the haplopore mould again.

The punching pin 2 is intact, and the noise absorption effect of the dense holes is good.

Example 2: the difference is that the diameter of the punch needle 2 is 3.2mm based on the embodiment 1.

Comparative example 1 easily caused deformation and damage of the brass plate.

Example 3: the difference is that the diameter of the punch needle 2 is 2.75mm based on the embodiment 1.

Comparative example 1 easily caused damage to the punch pin 2.

Example 4: the difference is that the distance between the central axes of the punching needles 2 is a =12mm, and the distance between the central axes of every two adjacent holes on the brass plate is b =6 on the basis of the embodiment 1.

The comparative example 1 has a smaller number of holes per one area, and thus has a reduced noise absorption effect.

Example 5: on the basis of the embodiment 1, the difference is that the central axis distance of the punching pin 2 is a =8.5mm, and the central axis distance b =4.25 of every two adjacent holes on the brass plate easily causes deformation and damage of the brass plate.

In the description herein, references to the description of "one embodiment," "an example," "a specific example," etc., mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
