Abstract
The invention provides a sound-absorbing cotton cutting device containing a teeth cutter. The sound-absorbing cotton cutting device containing the teeth cutter comprises a cutter, a fixing plate, an upper board and the teeth cutter, wherein one end of the cutter is fixed to the fixing plate; in addition, a shape into which the sound-absorbing cotton is processed is formed on the fixed plate by the cutter in an enclosed manner; the upper board is made of high-hardness steel with the hardness to be about 55 and can bear the stamping force above 100t; and the teeth cutter is arranged on the inner side of the cutter and is provided with tooth peaks and a tooth valley. According to the sound-absorbing cotton cutting device, during cutting, the stamping force is applied to the upper board, and the upper board and the cutter extrude and cut off the sound-absorbing cotton at high pressure; and meanwhile, the tooth peaks can cut off the sound-absorbing cotton, and the tooth valley cannot cut off the sound-absorbing cotton. By use of the sound-absorbing cotton cutting device, the production cost can be effectively reduced.
Description
Technical field
The present invention relates to a kind of acoustical cotton cutter sweep comprising serrated knife.
Background technology
Being the most all roughly the same in automotive type in the market, difference is the least, if product the least for difference is bought when producing automobile-used acoustical cotton or manufactured the production equipment of correspondence the most respectively, necessarily increases the cost of production.
Summary of the invention
A kind of acoustical cotton cutter sweep comprising serrated knife of offer is provided, is used for solving the problems referred to above so that the acoustical cotton product that difference is the least uses same equipment, to reduce production cost.
For reaching object above, the technical solution used in the present invention is: a kind of acoustical cotton cutter sweep comprising serrated knife, including cutter, fixed plate, upper face and serrated knife, cutter one end is fixed in fixed plate, and cutter surrounds acoustical cotton in fixed plate needs the shape of processing, upper face is made up of the glass hard steel that hardness is about 55, the punching press of more than 100t can be born, serrated knife is arranged on the inner side of cutter, serrated knife has tooth peak and tooth paddy, when cutting, upper face accepts stamping press, acoustical cotton is cut off with cutter high-pressure extrusion, tooth peak energy enough cuts off acoustical cotton simultaneously, tooth paddy can not cut off acoustical cotton.
Further, the tooth paddy width≤1.5mm of serrated knife 5, the tooth paddy degree of depth is 0.5 ~ 3mm, and tooth peak width is 10 times of tooth paddy width.
The invention have the advantage that serrated knife is configured according to the shape of new product, new old product can use same device, saves the cost buying device, also reduces management cost.
Accompanying drawing explanation
Fig. 1 is the structure chart of the cutting device of acoustical cotton.
Fig. 2 is the top view that cutter, serrated knife and fixed plate connect.
Detailed description of the invention
Hereinafter describe and be used for disclosing the present invention so that those skilled in the art are capable of the present invention.Preferred embodiment in below describing is only used as citing, it may occur to persons skilled in the art that other obvious modification.
nullSuch as Fig. 1 and Fig. 2，A kind of acoustical cotton cutter sweep comprising serrated knife，Including cutter 1、Fixed plate 2 and upper face 3，Cutter 1 has the edge of a knife，Cutter 1 is fixed in fixed plate 2 away from one end of the edge of a knife，Cutter 1 surrounds acoustical cotton 4 in fixed plate 2 needs the shape of processing，The technique in calligraphy angle of the edge of a knife of cutter 1 is bigger than general cutter，Can be more than 45 °，Upper face 3 is connected with pressing equipment，The tonnage of pressing equipment is more than 100T，The glass hard steel that upper face 3 uses hardness to be 55，When processing acoustical cotton 4，Fixed plate 2 is placed on bottom，The edge of a knife of cutter 1 exceeds fixed plate 2 and the height that the exceeds thickness more than acoustical cotton 4 to ensure to cut off acoustical cotton 4，Acoustical cotton 4 is placed on the top of the edge of a knife，Upper face 3 is placed on the top of acoustical cotton，I.e. acoustical cotton is placed between cutter 1 and upper face 3，The inner side of cutter 1 is provided with serrated knife 5 simultaneously，Width≤the 1.5mm of the tooth paddy 52 of serrated knife 5，Tooth paddy 52 degree of depth is 0.5 ~ 3mm，Tooth peak 51 width is 10 times of tooth paddy 52 width，Tooth peak 51 is apart from the height thickness more than acoustical cotton 4 of fixed plate and the height of the distance fixed plate of the edge of a knife top less than cutter 1 simultaneously，The height of the lowest point distance fixed plate of tooth paddy 52 is less than the thickness of acoustical cotton，When punching press，Tooth cutting edge of a knife or a sword 51 cuts off acoustical cotton 4，Tooth paddy 52 does not cut off acoustical cotton 4，But，The acoustical cotton 4 position after serrated knife 5 acts on can readily be torn，In this case，If the product of new research and development is little with the difference of old product，It it is only such as the hole that with the addition of some shapes on the basis of original，Have only to arrange corresponding serrated knife 5 in the relevant position of fixed plate，Same device can be used when producing new old product simultaneously，In order to obtain new product，Effect due to serrated knife 5，Acoustical cotton corresponding to the position of desired aperture is easy to tear with hands，And then obtain new product.
When producing, upper face 3 is heated to 80-120 °, pressing equipment promotes upper face 3 to move downward, the edge of a knife of cutter 1 and upper face 3 cut off acoustical cotton by high-pressure extrusion, the relevant position of acoustical cotton 4 is cut into the state easily torn by serrated knife 5, is torn by the acoustical cotton at serrated knife 5 active position as required.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; the principle of the simply present invention described in above-described embodiment and description; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements both fall within the range of claimed invention.The protection domain of application claims is defined by appending claims and equivalent thereof.
