Abstract
The utility model provides an anti-explosive impact plastic ultrasonic welding splicing face structure which comprises a plastic member A (1) and a plastic member B (2). The technical scheme of the utility model is that the cross section of a splicing face of the plastic member A is preset as a structure with a wedged groove and the cross section of a splicing face of the plastic member B is preset as a structure with a wedged tenon in the plastic members A and B needing to be welded. The anti-explosive impact plastic ultrasonic welding splicing face structure overcomes the problem and defect that the welding strength is low, the gas and water sealing performances are poor, and the anti-explosive impact capacity is not available in the prior art. By means of the engaging and splicing effect of the wedged groove and tenon, the purpose of improving the welding strength, enhancing the gas and water sealing performances and realizing the anti-explosive impact capacity is realized at the welded part of the plastic members.
Description
Technical field
The utility model relates to a kind of structure of solder side, specifically refers to for the Ultrasonic Plastic Member Welding, is preset at the plastic ultrasonic welding face of weld structure of a kind of anti-burst impact at plastic member face of weld place.
Background technology
The ultrasonic bonding of plastic member, need to preset at the end face of two mutual weldings of plastic member the face of weld structure that is beneficial to good welding, consult Fig. 2, prior art adopts the welding end face with a plastic member to preset to planar structure, the welding end face of another plastic member is preset to the structure that is provided with the molten muscle of triangular hill in planar central, during ultrasonic bonding, molten muscle melting is integrated the mutual welding of the end face of two plastic members; This face of weld structure is being used for having airtight, watertight requirement, when particularly having anti-burst to impact the welding of the plastic product that requires, leaking appears in weld easily, the local deformation dislocation easily occurs, weld strength and welding quality all can't meet the demands, therefore, prior art exists that weld strength is low, the air water airtight performance is poor, does not possess the problems and shortcomings of anti-burst impact capacity.
Summary of the invention
Problems and shortcomings for above-mentioned prior art existence, the utility model is taked in the plastic member of two of A, the B of need welding, the cross section of the face of weld of A plastic member is preset to structure with wedge-shaped slot, the cross section of the face of weld of B plastic member is preset to technical scheme with the structure of dovetail, the plastic ultrasonic welding face of weld structure that provides a kind of anti-burst to impact, be intended to utilize the engagement welding effect of wedge shape chase mortise, make the weld of plastic member reach the purpose that improves weld strength, enhancing air water airtight performance, possesses the anti-burst impact capacity.
The purpose of this utility model is achieved in that the plastic ultrasonic welding face of weld structure that a kind of anti-burst is impacted, comprise A plastic member, B plastic member, wherein: described A plastic member is wherein a plastic member in two the plastic member that need to be welded to each other, the face of weld of A plastic member is provided with the groove that cross section is wedge shape, is called wedge-shaped slot;
Described B plastic member is wherein another plastic member in two the plastic member that need to be welded to each other, the face of weld of B plastic member is provided with cross section and is dovetail corresponding with the described wedge-shaped slot position of A plastic member, that shape is coincide, protruded, be called dovetail, the width dimensions of described dovetail is greater than 0.1～0.2 millimeter of the width dimensions of the described wedge-shaped slot of A plastic member.
Operation principle and beneficial effect
During ultrasonic bonding, the described dovetail of B plastic member is wedged in the described wedge-shaped slot of A plastic member, make the face of weld of A plastic member and B plastic member intermeshing, supersonic welder is applied to the ultrasonic mechanical wave of A plastic member and B plastic member face of weld and the face of weld that longitudinal pressure makes A plastic member and B plastic member, comprise the surface of wedge-shaped slot and dovetail, fusion weld is integrated; Because wedge-shaped slot and dovetail is intermeshing, increased the surface area of A plastic member and the mutual welding of B plastic member, improved the air water airtight performance of weld, simultaneously, the intermeshing welding of wedge-shaped slot and dovetail makes weld possess the vertical and horizontal impact capacity of opposing explosion bulge test, has strengthened the anti-of weld mechanical robustness testing and has circumnutated and anti-shear ability.
Above-mentioned, the utility model is taked the A in the need welding, in the plastic member that B is two, the cross section of the face of weld of A plastic member is preset to structure with wedge-shaped slot, the cross section of the face of weld of B plastic member is preset to technical scheme with the structure of dovetail, having overcome prior art exists weld strength low, the air water airtight performance is poor, the problems and shortcomings that do not possess the anti-burst impact capacity, the plastic ultrasonic welding face of weld structure that a kind of anti-burst that provides is impacted, utilize the engagement welding effect of wedge shape chase mortise, make the weld of plastic member reach the raising weld strength, strengthen the air water airtight performance, the purpose that possesses the anti-burst impact capacity.
Description of drawings
Fig. 1 is that the plastic ultrasonic that a kind of anti-burst of the present utility model is impacted welds the structural representation of face of weld structure;
Fig. 2 is the structural representation of the plastic ultrasonic welding face of weld of prior art;
Below in conjunction with the embodiment in the accompanying drawing the utility model is described in further detail, but should not be construed as any restriction of the present utility model.
Among the figure: A plastic member 1, wedge-shaped slot 11, B plastic member 2, dovetail 21.
The specific embodiment
Consult Fig. 1～2, the plastic ultrasonic welding face of weld structure that a kind of anti-burst of the present utility model is impacted, comprise A plastic member 1, B plastic member 2, wherein: described A plastic member 1 is wherein a plastic member in two the plastic member that need to be welded to each other, the face of weld of A plastic member 1 is provided with the groove that cross section is wedge shape, is called wedge-shaped slot 11;
Described B plastic member 2 is wherein another plastic member in two the plastic member that need to be welded to each other, the face of weld of B plastic member 2 is provided with cross section and is dovetail corresponding with described wedge-shaped slot 11 positions of A plastic member 1, that shape is coincide, protruded, be called dovetail 21, the width dimensions of described dovetail 21 is greater than 0.1～0.2 millimeter of the width dimensions of the described wedge-shaped slot 11 of A plastic member 1.
Operation principle and beneficial effect
During ultrasonic bonding, the described dovetail 21 of B plastic member 2 is wedged in the described wedge-shaped slot 11 of A plastic members 1, make the face of weld of A plastic member 1 and B plastic member 2 intermeshing, supersonic welder is applied to the ultrasonic mechanical wave of A plastic member 1 and B plastic member 2 face of weld and the face of weld that longitudinal pressure makes A plastic member 1 and B plastic member 2, comprise the surface of wedge-shaped slot 11 and dovetail 21, fusion weld is integrated; Because wedge-shaped slot 11 and dovetail 21 is intermeshing, increased the surface area of A plastic member 1 and the 2 mutual weldings of B plastic member, improved the air water airtight performance of weld, simultaneously, wedge-shaped slot 11 and dovetail 21 intermeshing weldings make weld possess the vertical and horizontal impact capacity of opposing explosion bulge test, have strengthened the anti-of weld mechanical robustness testing and have circumnutated and anti-shear ability.
