Description
Technical field
The utility model relates to PPR pipeline bending field, relates in particular to the manually quick apparatus for bending of a kind of PPR tubing.
Background technology
At present, injection moulding pipeline application quantity in building trade increases gradually, as sewer pipe, water supply line, caliduct etc., in a lot of situations, running into two pipelines intersects mutually, but attractive in appearance in order to guarantee that pipeline is installed, need to set up bridging at infall, current processing mode mainly contains following several: the one, at infall, by union elbow, set up bridging, and make two pipelines still in same plane; The 2nd, direct enforceable installation, two pipelines press together mutually, if one is cold water pipe, one is hot-water line, has a large amount of exchange heat herein, causes temperature loss; The 3rd, by artificial bending, be generally to scald by hot water the place that will set up bending, then use the instruments such as hammer to force to knock, make it produce certain radian, in this, method wastes time and energy, and the radian of bending size irregular; Certainly, also have than relatively large bender, can be to the quick bending of the pipeline of PPR material, and the pipeline specifications after bending is unified, create an aesthetic feeling, but the general volume of this equipment is larger, be not easy to equipment carrying, especially when building pipeline is installed, every one deck, each is different according to design, and the bridging number of tubes of using is also different, can not be by whole equipment in reality along with the laying of pipeline and installation and follow movement, in a word, also do not have at present a structure relatively simple, the quick bending device of being convenient to carry.
Summary of the invention
The technical problems to be solved in the utility model is for the existing weak point of prior art, provides a kind of simple in structure, easy to use, can carry, and bending is effective, the manually quick apparatus for bending of PPR tubing that resilience is little.
Technical solution of the present utility model is, provide following a kind of PPR tubing manually quick apparatus for bending, comprise base, pressure roller and carrying roller, described base one side is provided with frame, frame top is hinged with the first depression bar, the first depression bar end is fixedly connected to second depression bar that becomes a angle with the first depression bar, is arranged with two pressure rollers on described the first depression bar and the second depression bar, and described base is provided with carrying roller.
Adopt above technical scheme, be convenient to PPR tubing to be suppressed into bridging on the one hand, the first depression bar of this apparatus for bending and the angled setting of the second depression bar on the other hand, mainly for guaranteeing when pressing down tubing, tubing is first subject to the carrying roller pretension effect on pressure roller and the base on the first depression bar, prevent pressurized hour offset and affect bending effect, two pressure rollers above, below a carrying roller, bending effect than a pressure roller upper, two carrying rollers are effective in lower bending, and tubing resilience is less.
As preferably, the angle a that described the first depression bar becomes with the second depression bar is opening up.Adopt the technical program, press down in process, first first pressure roller contacts with tubing, second subsequently, even if suppress level, because the second depression bar and the first depression bar have certain angle, so control stick do not contact with base, convenient operation.
As preferably, 100 °≤a≤135 ° of span at described a angle.Adopting the technical program, is the angle of summing up out through test of many times, and optimum can be chosen 120 °, both can guarantee firmly evenly, can guarantee again easy to operate.
As preferably, on described the first depression bar and the second depression bar, be equipped with several pin holes; In described pin hole, be provided with bearing pin; Two pressure rollers are coupling with the first depression bar and the second depression bar respectively by bearing pin.Adopt the technical program, can need the angle of bending, bridging length to regulate the position of two pressure rollers according to tubing, to meet different bridgings, the scope of application be wider.
As preferably, between described base and carrying roller, be provided with bearing, on described bearing, be connected with carrying roller.Adopt this technology, on the one hand for the effect of providing support for carrying roller, on the other hand can be according to the specification of the tubing that will bend, select to change suitable carrying roller.
As preferably, the roll extrusion periphery of pressure roller and carrying roller is provided with arc groove.Adopt the technical program, avoid tubing to be flattened.
As preferably, the end of described the second depression bar is provided with action bars.Adopt the technical program, convenient operation.
As preferably, described action bars end is provided with handle.Adopt the technical program, prevent from pressing down palm in process and skid.

The specific embodiment
For ease of explanation, below in conjunction with accompanying drawing, the manually quick apparatus for bending of the PPR tubing of utility model is elaborated.
As shown in Figure 1 to Figure 4, the manually quick apparatus for bending of a kind of PPR tubing, comprise base 1, base 1 one sides are provided with frame 4, frame 4 tops are hinged with the first depression bar 5, the first depression bar 5 ends be fixedly connected to one with second depression bar 6 at 5 one-tenth a angles of the first depression bar, the angle a of the first depression bar 5 and 6 one-tenth of the second depression bars is opening up, angle is 120 °, on described the first depression bar 5 and the second depression bar 6, be equipped with three pin holes 7, in described pin hole 7, be provided with bearing pin 8, two pressure rollers 2 are coupling with the first depression bar 5 and the second depression bar 6 respectively by bearing pin 8, and wherein two pressure rollers 2 are symmetrical arrangement, on the roll extrusion periphery of described pressure roller 2, all offer arc groove 12, the second depression bar 6 ends are provided with action bars 10, action bars 10 ends are provided with handle 11, base 1 is provided with bearing 9, on bearing 9, be connected with carrying roller 3, on the roll extrusion periphery of carrying roller 3, also offer arc groove 12, when PPR tubing is suppressed, press down the centre position that rear carrying roller 3 is just positioned at two pressure rollers 2.
Because the specification of PPR tubing is different, can select suitable pressure roller 2 and carrying roller 3 according to the specification of the actual PPR tubing of asking for bending, be coupling and be convenient to dismounting and change, be swift in motion, in addition, can be according to the tubing shape of asking for bending, adjust the position of pressure roller 2 on the first depression bar 5 and the second depression bar 6, the scope of application is more extensive.
In the above-described embodiments, preferred forms of the present utility model is described, obviously, under inventive concept of the present utility model, still can make a lot of variations.At this, should illustrate, any change of making under inventive concept of the present utility model all will fall in protection domain of the present utility model.
