Abstract
The invention provides a sound-absorbing cotton cutting device capable of edge heat-sealing. The sound-absorbing cotton cutting device capable of edge heat-sealing is characterized by comprising a cutter, a fixing plate, an upper board and a hot pressing die. The cutter is provided with a cutter edge; one end, far away from the cutter edge, of the cutter, is fixed on the fixing plate; the cutter is bent to form a to-be-processed shape, of a sound-absorbing cotton, on the fixing plate; the hot pressing die is arranged at the inner side of the cutter; the upper end of the hot pressing die is lower than the upper end of the cutter after the hot pressing die is fixed; the upper board is made of high-hardened steel which has the hardness being around 55 and can bear stamping equipment being 100t or above in tonnage; during slitting, the upper board is heated and then applied with stamping force, the upper board and the cutter extrude at high pressure to cut off the sound-absorbing cotton, and the hot pressing die seals the periphery of the cut-off sound-absorbing cotton. The slitting device is adopted so as to be capable of improving the production efficiency and improving the edge sealing effect.
Description
Technical field
The present invention relates to a kind of can the acoustical cotton cutter sweep of hot edge seal and cutting method thereof.
Background technology
In the parts that some are important, the edge sealing of acoustical cotton there is the highest requirement, the cut that uses at present, the edge sealing effect that hilted broadsword is die-cut, double-pole is die-cut etc. some can not meet edge banding requirements, particularly in pressure folding process, there will be chip phenomenon in various degree.
Summary of the invention
Present invention is primarily targeted at provide a kind of can the acoustical cotton cutter sweep of hot edge seal, be used for solving the problems referred to above, to improve the efficiency that acoustical cotton is cut, particularly improve edge sealing effect.
For reaching object above, the technical solution used in the present invention is: a kind of can the acoustical cotton cutter sweep of hot edge seal, including cutter, fixed plate, upper face and hot-die, cutter has the edge of a knife, cutter is fixed in fixed plate away from one end of the edge of a knife, and cutter surrounds acoustical cotton in fixed plate needs the shape of processing, the inner side of cutter is provided with hot-die, hot-die its upper end after fixation is less than the upper end of cutter, 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, when cutting, upper face is heated and then upper face is applied stamping press, acoustical cotton is cut off with cutter high-pressure extrusion, hot-die carries out edge sealing to the surrounding of acoustical cotton after cutting off.
Further, the technique in calligraphy angle of the edge of a knife of cutter is more than 45 °.
Further, the width of hot-die is 3-10mm.
Further, when cutting, upper face is heated to 100-120 °, it is possible to make acoustical cotton form slush state.
Further, described hot-die has glass fibre to make.
Further, the hot-die being made up of glass fibre uses justifying face forming by carving milling.
The present invention also provides for a kind of cutting method utilizing above-mentioned cutting device:
The first step: cutter surrounds in fixed plate acoustical cotton needs the shape of processing, is fixed in fixed plate along the inner side of cutter by pressing mold；
Second step: acoustical cotton is positioned between cutter and upper face；
3rd step: upper face is heated to 100-120 °；
4th step: upper face is applied stamping press, makes cutter and upper face extruding until cutting off acoustical cotton, and upper face makes hot-die be in slush state, and hot-die carries out edge sealing to the surrounding of the acoustical cotton after cutting off.
Further, the width of hot-die is 3-10mm.
The invention have the advantage that the technique in calligraphy angle of the edge of a knife due to cutter can efficiently reduce greatly the burr of otch, be effectively improved edge sealing effect；Further, owing to cutter surrounds the shape needing to cut in fixed plate, a punching press can shape, and is effectively improved production efficiency.
Accompanying drawing explanation
Fig. 1 is can the structure chart of acoustical cotton cutter sweep of hot edge seal
Fig. 2 is the top view that cutter, hot-die 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.
As illustrated in fig. 1 and 2, a kind of can the acoustical cotton cutter sweep of hot edge seal, including cutter 1, fixed plate 2, upper face 3 and hot-die 4, 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 5 in fixed plate 2 needs the shape of processing, and the technique in calligraphy angle of the edge of a knife of cutter 1 is bigger than general cutter, can be more than 45 °；Be provided with hot-die 4 in the inner side of cutter, the width of hot-die 4 is 3-10mm, and the upper end of hot-die 4 is less than the upper end of cutter, hot-die 4 has glass fibre to make, owing to glass fibre coefficient of elasticity is high, therefore, it can reach edge banding requirements by the contraction distortion of control hot-die 4；nullUpper 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，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 5，Acoustical cotton 5 is placed on the top of the edge of a knife，Upper face 3 is placed on the top of acoustical cotton 5，I.e. acoustical cotton 5 is placed between cutter 1 and upper face 3，Then，Upper face 3 is heated to 100-120 °，Pressing equipment promotes upper face 3 to move downward，The edge of a knife of cutter 1 cuts off acoustical cotton 5 with upper face 3 by high-pressure extrusion，And hot-die 4 and upper face 3 extrude the surrounding of acoustical cotton 5 but do not cut off acoustical cotton，Owing to upper face has higher temperature，The acoustical cotton being extruded region is made to form slush state，The edge sealing effect that can reach the highest it is extruded under slush state.
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.
