Description

A kind of acoustical cotton cutter sweep comprising serrated knife

Technical field

The utility model is related to a kind of acoustical cotton cutter sweep comprising serrated knife.

Background technology

All it is much roughly the same, difference very little in automotive type in the market, when automobile-used acoustical cotton is produced such as The product of difference very little is all bought or manufactures corresponding production equipment by fruit respectively, necessarily increases the cost of production.

Utility model content

Main purpose of the present utility model is to provide a kind of acoustical cotton cutter sweep comprising serrated knife, above-mentioned for solving Problem so that the acoustical cotton product of difference very little uses same equipment, to reduce production cost.

To achieve the above objectives, the technical solution adopted in the utility model is：A kind of cutting device of acoustical cotton, including knife Tool, fixed plate, upper face and serrated knife, cutter one end are fixed in fixed plate, and cutter surrounds acoustical cotton in fixed plate The shape of processing is needed, upper face, by 55 or so glass hard steel is made, can bear the punching press of more than 100t, serrated knife by hardness The inner side of cutter is arranged on, serrated knife has tooth peak and tooth paddy, in cutting, upper face receives stamping press, with cutter high-pressure extrusion Cut-out acoustical cotton, while tooth peak energy enough cuts off acoustical cotton, tooth paddy can not cut off acoustical cotton.

Further, the tooth paddy width of serrated knife 5<=1.5mm, tooth paddy depth is 0.5~3mm, and tooth peak width is tooth paddy width 10 times.

The utility model has the advantages that：Serrated knife is configured according to the shape of new product, and new old product can use same Individual device, saves the cost of purchase device, also reduces management cost.

Specific embodiment

Hereinafter describe for disclosing the utility model so that those skilled in the art can realize the utility model.Hereinafter retouch Preferred embodiment in stating is only used as citing, it may occur to persons skilled in the art that other obvious modifications.

Such 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, and cutter 1 is fixed in fixed plate 2 away from one end of the edge of a knife, and cutter 1 surrounds acoustical cotton 4 in fixed plate 2 The shape of processing is needed, 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 and punching press Equipment is connected, and the tonnage of pressing equipment is more than 100T, upper face 3 use hardness for 55 glass hard steel, when processing acoustical cotton 4 When, fixed plate 2 is placed on bottom, the edge of a knife of cutter 1 be higher by fixed plate 2 and the height that is higher by more than acoustical cotton 4 thickness with Acoustical cotton 4 is cut off in guarantee, and acoustical cotton 4 is placed on the top of the edge of a knife, and upper face 3 is placed on the top of acoustical cotton, i.e. acoustical cotton and is placed on Between cutter 1 and upper face 3, while being provided with serrated knife 5, the width of the tooth paddy 52 of serrated knife 5 in the inner side of cutter 1<=1.5mm, The depth of tooth paddy 52 is 0.5~3mm, and the width of tooth peak 51 is 10 times of the width of tooth paddy 52, while height of the tooth peak 51 apart from fixed plate , apart from the height of fixed plate, the lowest point of tooth paddy 52 is apart from fixed plate for thickness more than acoustical cotton 4 and the edge of a knife top less than cutter 1 Thickness of the height less than acoustical cotton, when punching press, the cut-out acoustical cotton 4 of tooth cutting edge of a knife or a sword 51, tooth paddy 52 do not cut off acoustical cotton 4, but, Acoustical cotton 4 can readily be torn at the position after the effect of serrated knife 5, in this case, if the product of new research and development Difference with old product is little, for example, be only the hole that some shapes are with the addition of on the basis of original, it is only necessary in fixed plate Relevant position corresponding serrated knife 5 is set, same device can be simultaneously used when new old product is produced, in order to newly be produced Product, due to the effect of serrated knife 5, are easy to be torn with hand, and then obtain new product corresponding to the acoustical cotton at the position in required hole.

In production, upper face 3 is heated to 80-120 °, pressing equipment promotes upper face 3 to move downward, the knife of cutter 1 Mouth cuts off acoustical cotton with upper face 3 by high-pressure extrusion, and the relevant position of acoustical cotton 4 is cut into serrated knife 5 shape easily torn State, as needed tears the acoustical cotton at the active position of serrated knife 5.

General principle of the present utility model, principal character and advantage of the present utility model has been shown and described above.One's own profession The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification Simply principle of the present utility model, the utility model also has respectively on the premise of the utility model spirit and scope are not departed from Changes and improvements are planted, these changes and improvements are both fallen within the range of claimed the utility model.The utility model requirement Protection domain defined by appending claims and its equivalent.
