Abstract
The utility model relates to bent pipe processing of pipelines of automotive air conditioners, in particular to a bent pipe core rod for alleviating distortion, which can be placed in a bent pipe and is provided with a core rod and a core rod ball joint for supporting a bent portion of the bent pipe. The core rod is hinged to the core rod ball joint. The bent pipe core rod for alleviating the distortion is simple in structure and convenient to operate, can be in common use with an existing ordinary straight core rod, reduces collapse and fracture of the bent pipe, alleviates the distortion of the outer diameter of the bent pipe, reduces defect rate in the bent pipe processing and improves quality of outer pipes of pipe fittings.
Description
Technical field
The utility model relates to the bend pipe processing of air conditioning for automobiles pipeline, especially a kind of bend pipe plug that alleviates distortion.
Background technology
In the bend pipe process of metal tube, the length of pipe fitting central shaft is constant, and the bending section outside can be stretched, wall thickness is attenuation gradually, the surface easily inwardly subsides, the inboard then is squeezed, wall thickness is thickening gradually, be easy to generate wrinkle simultaneously, in the bend pipe process, the deformation that pipe fitting produces mainly appears in curved zone when beginning to crooked 30 °, and tube chamber inside can add straight plug when bend pipe usually, and directly the support of plug can be played certain improvement, but bending under the less situation of light-wall pipe and bending radius, more than these defectives still can exist, the when serious even pipe fitting outside can produce breaks, the effect of the straight plug of general elbow is very limited.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of bend pipe plug that alleviates distortion is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of bend pipe plug that alleviates distortion, can be positioned in the bend pipe, and have mandrel stem and the plug bulb that is used to support the bend pipe bend, mandrel stem and plug bulb are hinged.
Described articulated form is that fixedly chain nodal plate is installed in the mandrel stem, and the activity chain nodal plate is installed in the plug bulb, and fixedly the chain nodal plate is connected with the activity chain nodal plate, and mandrel stem is with fixedly chain nodal plate, plug bulb are fixedlyed connected by pin with hunting link.
The beneficial effects of the utility model are: the utility model is simple in structure, and is easy to operate, can be general with existing ordinary straight plug, and reduce bend pipe and subside, break, reduce the distortion of bend pipe external diameter, and reduce bend pipe processing fraction defective, improve pipe fitting outer tube quality.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a working state schematic representation of the present utility model.
Among the figure: 1. mandrel stem, 2. plug bulb, 3. fixedly chain nodal plate, 4. activity chain nodal plate, 5. pin.
The specific embodiment
In conjunction with the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
The bend pipe plug that alleviates distortion as depicted in figs. 1 and 2, can be positioned in the bend pipe, have mandrel stem 1 and the plug bulb 2 that is used to support the bend pipe bend, mandrel stem 1 is hinged with plug bulb 2, articulated form is that fixedly chain nodal plate 3 is installed in the mandrel stem 1, activity chain nodal plate 4 is installed in the plug bulb 2, and fixedly chain nodal plate 3 is connected with activity chain nodal plate 4, and mandrel stem 1 is with fixedly chain nodal plate 3, plug bulb 2 are fixedlyed connected by pin 5 with hunting link 4.
Before the bend pipe, plug bulb 2 is gone to horizontal level, plug can easily be packed into as ordinary straight plug quilt, during bend pipe work, pipe fitting begins to be out of shape gradually along bend wheel mould, and the plug bulb is also followed the bending of pipe fitting and rotated, and plays a part to support to reduce at the main deformation section of pipe fitting inner chamber and is out of shape, when taking out pipe fitting after bend pipe is finished, plug bulb 2 will be returned to curved preceding base level position by the straight length at pipe fitting rear portion.
Above-mentioned embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model spirit essence change or modify, and all should be encompassed in the protection domain of the present utility model.
