Abstract
The invention discloses a multi-purpose pipe bending mould which comprises a fixed mould and a movable mould. The multi-purpose pipe bending mould is characterized in that a special-shaped processing groove is formed on the movable mould and is formed by connecting two arc surfaces of different radii, the middle portion of the special-shaped processing groove is a first arc surface, two ends of the first arc surface are respectively connected with a second arc surface, the first arc surface and the second arc surface are smoothly connected, and a semi-circular processing groove is formed on the fixed mould. By improving processing grooves of the movable mould and a guide plate, the multi-purpose pipe bending mould can meet the requirement of bending pipes of different diameters. The multi-purpose pipe bending mould has the advantages of being capable of reducing mould manufacturing quantity greatly, reducing mould costs, shortening mould changing time, improving production efficiency, and integrating the management optimization and the design standard of the mould.
Description
Technical field
The present invention relates to air conditioning for automobiles pipeline bend pipe field, specifically a kind of versatility bend pipe mould that can adapt to different pipeline calibers.
Background technology
As Fig. 1, the bend pipe usual way is that movable mold 1 clamps pipeline with fixed die 3 at present, and guide plate 2 is the purpose that radius is realized bend pipe with fixed die 3.Because it is consistent all following caliber in the movable mold in bend pipe field with the guide plate working groove, therefore one pair of mould can only be at a kind of caliber, more because of the caliber that air-conditioning duct is different, a large amount of moulds adapts to different calibers and each die change is all pretty troublesome so need to make.
Summary of the invention
The object of the present invention is to provide a kind of versatility bend pipe mould to adapt to more caliber, it has broken away from mould by the constraint of caliber, has realized the versatility of mould and has reduced mould development expense and mould replacing time.
To achieve these goals, technical scheme of the present invention is: a kind of versatility bend pipe mould, comprise fixed die, movable mold is characterized in that this movable mold offers special-shaped working groove, and this abnormity working groove is formed by connecting by the arc surface of two kinds of different radiis, middle part that wherein should the abnormity working groove is first arc surface, the first arc surface two ends are connected with second arc surface respectively, smooth connection between first arc surface and second arc surface, and fixed die has semicircle working groove.
The present invention makes the mould realization to the requirement of different tube diameters bend pipe by to utilizing the working groove to movable mold and guide plate to improve.The invention has the advantages that and to reduce the mould manufacturing greatly, reduce die cost; Shorten mould replacing time, the production efficiency of raising realizes the management optimization of mould and the unification of design standard.
Description of drawings
Fig. 1 is the structural representation of the bend pipe mould of prior art.
Fig. 2 is the structural representation of movable mold of the present invention.
Fig. 3 is the use state diagram of bend pipe mould of the present invention.
The specific embodiment
As shown in Figure 2, a kind of versatility bend pipe mould, comprise fixed die 5, the movable mold 4 that matches with fixed die 5 and guide plate (not shown), an end that it is characterized in that this movable mold 4 offers special-shaped working groove, this abnormity working groove is formed by connecting by the arc surface of two kinds of different radiis, middle part that wherein should the abnormity working groove is first arc surface, its radius is R1, two ends are connected with second arc surface respectively, its radius is R2, R2 wherein〉R1, smooth connection between first arc surface and second arc surface (tangent connection between first arc surface and second arc surface), fixed die has the semicircle working groove that matches with described special-shaped working groove, and the working groove radius is decided according to caliber.According to a preferred embodiment of the invention, the first arc surface radius R 1 is 4 ~ 8mm, and the second arc surface radius R 2 is 6 ~ 30mm, and the working groove depth H is 3 ~ 10mm, and the width of working groove is 9 ~ 20mm.
Owing to use the movable mold among Fig. 1 and guide plate instead bend pipe mould of the present invention, broken away from circular design, from circular whole stressed changed into linear stressed.As shown in Figure 3, one end of fixed die is provided with semi-circular recesses, bend pipe 6 is placed between the working groove of semicircle and this movable mold 4 of fixed die 5, regulate then and fixed die between the gap realize clamping the purpose (F represent bend pipe mould follow the gap between the fixed die) of bend pipe, the bend pipe caliber is more big, and then gap F is more big.The distance of F generally clamps bend pipe and get final product, is difficult for excessive otherwise to understand the bend pipe ovality not enough, also is difficult for too small otherwise can to press from both sides seal dark excessively.Though only show the structural representation of movable mold among the figure, but those skilled in the art should understand, guide plate also can adopt similar structure to realize, be that the end that guide plate cooperates with fixed die is also offered special-shaped working groove, this abnormity working groove is formed by connecting by the arc surface of two kinds of different radiis, middle part that wherein should the abnormity working groove is first arc surface, its radius is R1, two ends are connected with second arc surface respectively, its radius is R2, R2 wherein〉R1, smooth connection between first arc surface and second arc surface (tangent connection between first arc surface and second arc surface).
According to one embodiment of present invention, the first arc surface radius R 1=4mm of abnormity working groove, the second arc surface radius R 2=7mm, the working groove depth H is 3.38mm, width is 10mm, and the bend pipe that this bend pipe mould can adapt to Φ 8 to Φ 12.7 different tube diameters requires (as Fig. 2 a); According to another embodiment of the present invention, the first arc surface radius R 1=6.5mm of abnormity working groove, the second arc surface radius R 2=30mm, the working groove depth H is 8.5mm, width B is 18mm, and the bend pipe that this bend pipe mould can adapt to Φ 14.5 to Φ 19.05 different tube diameters requires (as Fig. 2 b).
