Description
Technical field
The utility model relates to the production field of noise eliminator of motorcycle parts, is specifically related to a kind of irregular sandbag for bending bimetallic tube.
Background technology
Noise eliminator of motorcycle is generally made up of a few parts such as blast pipe, connection swivel nut, silencing pot and cylinder cores.Noise eliminator of motorcycle is generally made up of a few parts such as blast pipe, connection swivel nut, silencing pot and cylinder cores.Noise eliminator of motorcycle a kind ofly allows air-flow to lead to and the device of attenuate acoustic noise, it is one of important spare part on motorcycle, the quality of Muffler Performance not only affects the size of motorcycle noise, and has considerable influence to the performance such as function, oil consumption, moment of torsion of engine.
When the blast pipe of the motor vehicle such as automobile, motorcycle manufactures, need to carry out bend pipe processing to bimetallic tube.Because bimetallic tube has inside and outside two-layer tube wall, be difficult to ensure that the spacing of outer tube and interior pipe after bimetallic tube machines keeps equal, increase difficulty of processing, therefore, need to take certain technical measures, in prior art, adopt perfusion fluid in the interlayer of bimetallic tube, make it freezing by cooling, again by bimetallic tube cold roll forming, then wash away the interlayer of bimetallic tube, then fill thing in dissolving, finally drying process is carried out to bimetallic tube.By above-mentioned processing mode, its weak point is: energy consumption is higher, and the corrosivity of freezing liquid is comparatively strong simultaneously, can affect the service life of equipment.
After by perfusion fluid in the interlayer of bimetallic tube, in prior art, propose and replace pouring liquid in the interlayer of bimetallic tube by fine sand, in bimetallic tube pipe outer wall on be fixed on the inwall of outer tube by two iron blocks as bracing frame, fill with Sha Houzai and carry out bend pipe processing, after bimetallic tube machine-shaping, pour out fine sand again.The weak point existed is: collect inconvenience, and consuming time longer.
Utility model content
The purpose of this utility model is to provide a kind of short, convenient irregular sandbag for bending bimetallic tube collected consuming time.
The base case that this programme provides is: for bending the irregular sandbag of bimetallic tube, comprise the first sandbag and the second sandbag, the two ends of described first sandbag and the second sandbag all seal, the shape of described first sandbag and the second sandbag is hollow cylindrical, described second sandbag is made up of multiple arc sandbag, one end of described first sandbag is provided with multiple groove, and one end of described second sandbag is provided with multiple projection, and described projection and groove can clampings.
The principle of this programme and advantage: during operation; first sandbag and the second sandbag are put into the interlayer of bimetallic tube; due to the groove on the first sandbag and the protruding phase clamping on the second sandbag; play the effect of a location; when bimetallic tube bending process; make mutually to extrude more consolidation between the fine sand in sandbag; better protect the structure in double-deck shop; simultaneously sandbag put into easily with take out overcome fills with husky with fall sand time length consuming time problem, also overcome the collection problem to fine sand after processing.
Preferred version one: based on the preferred version of scheme, described second sandbag is made up of two arc sandbags, by above-mentioned setting, can arrange the number of arc sandbag according to demand, finally form hollow cylindrical and fill the interlayer of bimetallic tube, quantity fewer taking-up sandbag consuming time shorter.
Preferred version two: based on the another preferred version of scheme, described first sandbag is provided with the first baffle plate away from one end of groove, described second sandbag is provided with second baffle away from one end of projection, by arranging the first baffle plate and second gear board outside bimetallic tube pipe end, the first sandbag and the position of the second sandbag in bimetallic tube interlayer can be limited.
Preferred version three: the preferably preferred version of two, described first baffle plate and second baffle be equipped with handpiece, by being arranged on the handpiece on the first baffle plate and second baffle, can more convenient taking-up first sandbag and the second sandbag after bimetallic tube machines.
Preferred version four: based on the another preferred version of scheme; the groove of described first sandbag is set to two and is square; it is square that the projection of described second sandbag is set to match with groove shapes; by setting party's connected in star and square projection; can make bimetallic tube add man-hour stressed evenly, the better structure of protection bimetallic tube.
Accompanying drawing explanation
Fig. 1 is that the utility model is for bending the schematic diagram of the irregular sandbag first sandbag embodiment of bimetallic tube;
Fig. 2 is that the utility model is for bending the schematic diagram of the irregular sandbag second sandbag embodiment of bimetallic tube;
Fig. 3 is that Fig. 1 first sandbag is along A-A sectional structure schematic diagram;
Fig. 4 is that Fig. 2 second sandbag is along B-B sectional structure schematic diagram.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: the first sandbag 10, groove 11, the first plate washer 12, second sandbag 20, protruding 21, second plate washer 22, baffle plate 30, handpiece 31.
Embodiment is basic as accompanying drawing 1, Fig. 2, shown in Fig. 3: for bending the irregular sandbag of bimetallic tube, comprise the first sandbag 10 and the second sandbag 20, the two ends of the first sandbag 10 and the second sandbag 20 all seal, the shape of the first sandbag 10 and the second sandbag 20 is hollow cylindrical, second sandbag 20 is made up of two arc sandbags, one end of first sandbag 10 is provided with the square groove 11 of two same sizes, one end of second sandbag 20 is provided with square protruding 21 of two same sizes, projection 21 clamping of projection 21 and groove 11, first sandbag 10 is provided with the first baffle plate 12 away from one end of groove 11, second sandbag 20 is provided with second baffle 22 away from one end of protruding 21, first baffle plate 12 and second baffle 22 are equipped with handpiece 31, handpiece 31 is set to circular arc and connected mode is pin joint.
In the present embodiment, during operation, when carrying out bending process to bimetallic tube, owing between the outer tube of bimetallic tube and interior pipe being fixedly by two iron blocks as bracing frame, therefore the first sandbag 10 needs one, and the second sandbag 20 needs two.First, the place of processing double-layer pipe in needs bending is measured, correspondence arranges the length of the first sandbag 10 and the second sandbag 20, first sandbag 10 is filled in from bimetallic tube one end, second sandbag 20 is filled in from the other end of bimetallic tube, when one end that bimetallic tube filled in by the first sandbag 10 and the second sandbag 20 all arrives the place of bending, square groove 11 on first sandbag 10 and the square protruding 21 phase clampings on the second sandbag 20, the first baffle plate 12 and second baffle 22 all keep off the end face at bimetallic tube simultaneously; Then, during to bimetallic tube bending process, due to square groove 11 and square protruding 21 phase clampings, play the effect of a location, make between the fine sand in sandbag compacter simultaneously, better protect the structure in double-deck shop; Finally, after bimetallic tube machines, by handpiece 31 manually pull-out sandbag.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
