Abstract
The utility model discloses a rotatory friction weld's bag formula filter shell, including epitheca and inferior valve, be equipped with cyclic annular sand grip on the composition surface that inferior valve and epitheca are connected, be equipped with ring groove on the composition surface that epitheca and inferior valve are connected, in cyclic annular sand grip and the incorporation of ring groove kissing imbedded ring groove, epitheca and inferior valve material were thermoplastic material, the utility model discloses an uneven composition surface structure makes rotatory friction weld's frictional force improve, can produce more frictional heats, and the deep of assurance composition surface is merged, possesses higher welding quality, and simultaneously, less weld time has improved welding efficiency, does not have welding smog and also reduces the pollution to the environment.
Description
Technical field
The utility model relates to a kind of filtration art, refers more particularly to the bag type filter shell that a kind of resistance to pressure is good, the spin friction of use safety is welded.
Background technology
Bag type filter shell generally adopts upper and lower two-part structure, after inner member has assembled, utilize sweat soldering technique that upper and lower two-part structure is welded into an entirety, ensure that shell has good sealing and structural strength, but need heater be utilized due to sweat soldering, can smog be produced in welding process, affect environmental quality, and deep layer welding quality cannot ensure, cause shell withstand voltage properties not high, affect the security that product uses.
Utility model content
The bag type filter shell resistance to pressure smog that is not high, welding generation that the utility model mainly solves existing sweat soldering affects again the technical problem of environmental quality; Provide the bag type filter shell that a kind of resistance to pressure is good, the spin friction of use safety is welded.
In order to solve the technical problem of above-mentioned existence, the utility model mainly adopts following technical proposals:
The bag type filter shell of a kind of spin friction welding of the present utility model, described bag type filter shell comprises upper casing and lower casing, the solder side that described lower casing is connected with upper casing is provided with ring-type raised line, the solder side that described upper casing is connected with lower casing is provided with annular recess, described ring-type raised line and described annular recess kissing merge in embedded rings shape groove, upper casing and lower shell material are thermoplastic, adopt uneven composition surface structure, the frictional force that spin friction is welded improves, produce more frictional heat, ensure that the deep layer on composition surface merges and possesses higher welding quality, simultaneously, less weld interval improves welding efficiency, welding smog also reduces the pollution to environment.
As preferably, the lateral cross section of described ring-type raised line is in the shape of the letter V, and described annular recess is V-shaped groove, both contact surfaces are larger, pressing, the rotating friction force under cooperation use is very big, produces more frictional heat thus and melts composition surface, forming the composition surface of high strength under responsive to axial force.
As preferably, described upper casing and lower shell material are polypropylene or polyethylene or ABS resin.
The beneficial effects of the utility model are: housing adopts uneven composition surface structure, the frictional force of upper-lower casing is improved, more frictional heat can be produced when spin friction is welded, ensure that the deep layer on composition surface merges, possesses higher welding quality, meanwhile, less weld interval also improves welding efficiency, and welding smog also reduces the pollution to environment.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
1. upper casings, 2. lower casing in figure, 3. ring-type raised line, 4. annular recess.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the bag type filter shell of a kind of spin friction welding of the present embodiment, as shown in Figure 1, comprise upper casing 1 and lower casing 2, the composition surface that lower casing is connected with upper casing is designed with ring-type raised line 3, the lateral cross section of ring-type raised line is in the shape of the letter V, and the composition surface that upper casing is connected with lower casing is designed with annular recess 4, and annular recess is V-shaped groove, ring-type raised line and annular recess kissing merge in embedded rings shape groove, and upper casing and lower shell material are polypropylene thermoplastic material.
When spin friction is welded, the compressed air pressure on electroplating equipment wielding machine is adjusted to 4kgf/cm
2upper casing and lower casing are tightly pressed together, then the rotary speed of electroplating equipment wielding machine is adjusted to 450 revs/min, rotating cycle is adjusted to 5 circles, electroplating equipment wielding machine starts, now, rotating friction force between upper casing and lower casing is very large, the annular recess surface of the ring-type raised line of upper casing surface and lower casing is melted by consequent a large amount of spin friction heat, upper casing and lower casing composition surface are melted and are bonded to an entirety, machinery to be welded stops and namely completing the welding of upper casing and lower casing after cooling, and the parameter adjustment of electroplating equipment wielding machine is as the criterion with the requirement of welding procedure.
In description of the present utility model, technical term " on ", D score, " front ", " afterwards ", " interior ", " outward " etc. represent that direction or position relationship are based on direction shown in the drawings or position relationship, be only for convenience of description with understand the technical solution of the utility model, more than illustrate and not restriction has been done to the utility model, the utility model is also not limited only to the citing of above-mentioned explanation, the change that those skilled in the art make in essential scope of the present utility model, remodeling, increase or replace, all should be considered as protection domain of the present utility model.
