Abstract
The invention discloses a method and special equipment for preparing a sheet-shaped piece into a pipe-shaped piece. The method comprises the following steps: firstly, folding the sheet-shaped piece and carrying out die cutting on the folded sheet-shaped piece by an ultrasonic pressing die head along a fold direction; and finishing fusion welding of the edge of the sheet-shaped piece in the die cutting process to form the pipe-shaped piece with a uniform welded junction. The special equipment comprises a base, an auxiliary shaft and the ultrasonic pressing die head, wherein the base is provided with a die cutting cutter and an auxiliary shaft seat; the auxiliary shaft seat is provided with an auxiliary shaft groove which is open towards the die cutting cutter. The sheet-shaped piece is prepared into the pipe-shaped piece by adopting an ultrasonic pressing die head die cutting manner, a welding position is uniform and burrs are not formed, so that the defects in the prior art that the welded junction of the pipe-shaped piece manufactured by a spinning and sewing process is not uniform and the burrs are easy to form are overcome.
Description
Technical field
The present invention relates to a kind of Medical Devices, particularly a kind of tube-like piece of Medical Devices.
Background technology
In the Medical Devices such as breathing mask, need to use tube-like piece, current tube-like piece has the textile cloth such as plastic material and nylon two kinds, the tube-like piece of plastic material is easily produced, but the tube-like piece of plastic material is airtight, after patient worn, tube-like piece is close to skin, and comfortableness is poor.The tube-like piece of cloth material has the features such as ventilative, can improve the comfortableness worn, but its production technology is more a lot of than the tube-like piece difficulty of plastic material.
The tube-like piece of current cloth material adopts the mode by the weaving of the edge of sheet shaped piece is sewed up to produce, and on the one hand, suture site is smooth not, attractive in appearance, and on the other hand, suture site easily forms cotton-shaped burr or loose limit.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of interface neat, method and the special equipment of sheet shaped piece being made tube-like piece of burr can not be produced.
The technical solution adopted for the present invention to solve the technical problems is:
Sheet shaped piece is made a method for tube-like piece, first by sheet shaped piece doubling, then along doubling direction, adopt the sheet shaped piece after the doubling of ultrasonic wave pressing die head cross cutting, while cross cutting, complete the melting welding at sheet shaped piece edge, form the tube-like piece that weld bond is neat.
Sheet shaped piece is made a special equipment for tube-like piece, comprise base, auxiliary axle and can in opposite directions or the ultrasonic wave pressing die head of Divergence base motions, described floor installation has die-cutting rule and auxiliary axle bed, and described auxiliary axle bed is provided with the auxiliary axial trough of opening towards described die-cutting rule.
The inner of described auxiliary axial trough is provided with arc groove.
Described auxiliary axle bed is provided with bar shaped fixing hole, and the length direction of described bar shaped fixing hole is vertical with the length direction of described die-cutting rule.
The invention has the beneficial effects as follows: the present invention adopts the mode of ultrasonic wave pressing die head cross cutting that sheet shaped piece is made tube-like piece, welding position is neat, can not burr be produced, solve in prior art the tube-like piece interface adopting weaving sewing process to make not neat, easily produce the defect of burr.

Detailed description of the invention
Sheet shaped piece is made a method for tube-like piece, the method is first by sheet shaped piece doubling, then along doubling direction, adopts the sheet shaped piece after the doubling of ultrasonic wave pressing die head cross cutting, completes the melting welding at sheet shaped piece edge, form the tube-like piece that weld bond is neat while cross cutting.The material of sheet shaped piece can be the flexible materials such as plastics, woven fabric, nylon and thin sheet of metal.
Special equipment sheet shaped piece being made tube-like piece comprises base 1, auxiliary axle 2 and can in opposite directions or the ultrasonic wave pressing die head 3 of Divergence base motions, the actuating unit of ultrasonic wave pressing die head 3 can be cylinder or motor etc., described base 1 is provided with die-cutting rule 4 and auxiliary axle bed 5, the blade of described die-cutting rule 4 is triangle, described auxiliary axle bed 5 is provided with the auxiliary axial trough 6 of opening towards described die-cutting rule 4, and the inner of described auxiliary axial trough 6 is provided with arc groove 7.
Described auxiliary axle bed 5 is provided with bar shaped fixing hole 8, the length direction of described bar shaped fixing hole 8 is vertical with the length direction of described die-cutting rule 4, auxiliary axle bed 5 is screwed on base 1, according to the diameter of tube-like piece, can adjust the distance of auxiliary axle bed 5 apart from die-cutting rule 4.
During work, as shown in Figure 4, first sheet shaped piece 9 is placed on base, then as shown in Figure 5, auxiliary axle 2 moves manually or in the auxiliary axial trough 6 of mechanical straps trend, pulls in auxiliary axial trough 6 by sheet shaped piece along folding position, after putting in place, auxiliary axle 2 enters arc groove 7, by the sheet shaped piece tensioning of doubling, then as shown in Figure 6, ultrasonic wave pressing die head 3 presses down, complete die cutting operation, while cross cutting, complete the melting welding at sheet shaped piece edge, the tube-like piece that formation weld bond is as shown in Figure 7 neat.
