Embodiment
Below against accompanying drawing, by the description to embodiment, the embodiment to the present invention makees further details of
Explanation.
Bend pipe mould of the present invention, as shown in Figure 1, 2, including roller 6 and sliding formwork 9, roller 6 is circumferentially with roller groove, sliding formwork 9
Provided with the sliding formwork groove 91 relative with roller groove, the section of sliding formwork groove 91 is half elliptic structure, and pipe is placed in into roller 6 and sliding formwork 9
Between, roller 6 is rotated in the axial direction, the feed motion in the horizontal direction of sliding formwork 9, is cooperated and is promoted pipe to carry out bend pipe.
In the present invention, bend pipe mould also includes the clamping device of clamping pipe, and control pipe is oriented to, to realize stable continue
Bend pipe process.In the embodiment of the present invention, clamping device is included located at the clamping 8 of the direction of feed front end of sliding formwork 9 and located at roller 6
The upper fixture block 7 relative with clamping 8.Clamping 8 and fixture block 7 are provided with the clamping hole for being engaged and constituting complete circle.Forming process, folder
The inactive state of block 7 drives synchronous push ahead of clamping 8 to accommodate pipe in a mold by sliding formwork 9；Roller 6 is rotated about the axis, suitable
Hour hands are rotated, and sliding formwork 9 is fed forward at the same rate, in the process, and guarantee pipe preferably has 0.2mm or so with mould
The gap of size；Sliding formwork 9 and clamping 8 are retreated after the completion of bend pipe, and it is the pipe fitting after being molded to take out pipe.
Distance is equal to pipe diameter at the opening of sliding formwork groove 91.
The bend pipe mould of the present invention, half elliptic structure is designed as by sliding formwork groove 91, with real by ellipse arc design feature
Now facilitate bend pipe, can still realize good bend pipe to the less situation of elbow radius, solve that the big wall of elbow radius is thin to be occurred
Rough, inner ring has the underproof problem of fold, elbow roundness, can replace cancelling in pipe using concrete-cored, it is to avoid to pipe
The damage of wall.The design method of sliding formwork groove 91, as shown in Figure 3,4, is comprised the following steps that thereon：
1) circle I 1 is first drawn as basic circle, and distance is D, i.e. pipe pipe diameter size at the opening of sliding formwork groove 91；
2) the center line line I of circle I 1 is offset downward into 0.55D, forms line II, Fig. 2, offset distance d, d=shown in 3
0.55D；
3) circle II 2 that radius is 0.37D is drawn, the center of circle and I 1 centers of circle of circle of circle II 2 are located along the same line, and with round II 2
It is tangent with line II；
4) circle III 3 that radius is (0.95D-0.37D) is drawn, circle III 3 is concentric circles with circle II 2；
5) it is 0.95D circles IV 4 to draw radius, and the intersection point using line II and circle I 1 is the center of circle；
6) circle V 5 that radius is 0.95D is drawn, the intersection point of the top of circle I 1 is located at as the center of circle using circle III 3 and circle IV 4.
7) using the vertical center line of circle II 2 as the symmetrical center line of semiellipse, circle II 2 close to one section of lower section and with its phase
One section of composition a quarter that the circle V 5 of friendship is upwardly extended is oval.
Bend pipe mould in the present invention, the sliding formwork groove 91 for the half elliptic designed by design method of the present invention is applicable
In the less bend pipe of elbow radius；Solve that bend pipe footpath is big and wall is thin occurs that rough, inner ring has fold, elbow roundness not
Qualified situation；Can need not concrete-cored rod carry out bend pipe, it is to avoid damage is caused to tube wall, can not be concrete-cored when solving part pipeline bend pipe
The situation of rod.The bend pipe mould is simple in construction, is easy to forming elbow, can improve bend pipe qualification rate, and applicability is wider.
The present invention is exemplarily described above in conjunction with accompanying drawing, but the present invention is not limited to aforesaid way, only
The improvement for the various unsubstantialities to be carried out using the inventive concept and technical scheme of the present invention directly applies to other occasions
, all fall within protection scope of the present invention.
