Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a technical field of mould, concretely relates to a mould for being bent to pipe fitting.
[ background of the invention ]
Bending of tubes is typically accomplished with a tube bender. For bending of small pipes, the pipe bender can also be realized, but for the enterprises using the pipe bender, the purchasing of the pipe bender requires large cost, and the cost is inevitably increased greatly. Therefore, when many enterprises bend small pipes, the manual bending mode is usually adopted, so that the product quality cannot be ensured.
[ Utility model ] content
In order to solve the problem, an object of the utility model is to provide a can carry out the mould of bending to small-size pipe fitting.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a mould for bending pipe fitting, including fixed lower mould and the last mould that can reciprocate, be provided with the recess in the upper surface of lower mould, the length of recess is corresponding with the length when the pipe fitting is not bent, is provided with two pivots in the recess, is provided with rotatory piece in the every pivot, and two rotatory pieces are symmetrical with the axis of recess and are set up, and the lower part of every rotatory piece is provided with the lug, and the bottom surface of lug is inconsistent with the diapire of recess, laminates each other between the adjacent lateral wall of two rotatory pieces, forms middle sunken contained angle between the upper surface of two rotatory pieces, the below of going up the mould is provided with the depression bar, and the axis of depression bar coincides mutually with the axis of recess, and the bottom of depression bar is middle convex triangular structure, and its middle bulge is the circular arc transition.
The utility model provides a mould that is used for bending the pipe fitting further sets up to: the adjacent lateral wall of two rotatory pieces is the face of buckling, and the adjacent lateral wall in upper portion of two rotatory pieces is laminated each other, and the adjacent lateral wall phase separation in lower part of two rotatory pieces.
The utility model provides a mould that is used for bending the pipe fitting further sets up to: an upper protection plate made of soft materials is arranged at the bottom of the pressure lever.
The utility model provides a mould that is used for bending the pipe fitting further sets up to: the upper surface of the rotating block is provided with a lower protection plate made of soft materials.
Compared with the prior art, the utility model discloses following beneficial effect has: foretell a mould for bending pipe fitting, its simple structure, convenient to use have not only realized bending to small-size pipe fitting, can also avoid the pipe fitting surface to receive the damage, and the angle of bending of control that moreover can be accurate has guaranteed the quality of product.
[ description of the drawings ]
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. the device comprises a lower die, 2, an upper die, 3, a groove, 4, a pipe fitting, 5, a rotating shaft, 6, a rotating block, 7, a convex block, 8, a pressure rod, 9, an upper protection plate, 10 and a lower protection plate.
[ detailed description ] embodiments
The die for bending a pipe according to the present invention is further described in detail below with reference to the following embodiments.
As shown in fig. 1, a mould for bending pipe fitting, including fixed lower mould 1 and the last mould 2 that can reciprocate, be provided with recess 3 in the upper surface of lower mould 1, the length when recess 3's length and pipe fitting 4 are not bent is corresponding, is provided with two pivot 5 in the recess 3, is provided with rotatory piece 6 on every pivot 5, and two rotatory pieces 6 are symmetrical with the axis of recess 3 and are set up, and the lower part of every rotatory piece 6 is provided with lug 7, and the bottom surface of lug 7 is inconsistent with the diapire of recess 3, the adjacent lateral wall of two rotatory pieces 6 is the face of buckling, and the adjacent lateral wall in upper portion of two rotatory pieces 6 laminates each other, and the adjacent lateral wall phase separation in lower part of two rotatory pieces 6. Sunken contained angle in the middle of forming between the upper surface of two rotatory pieces 6, the below of going up mould 2 is provided with depression bar 8, and the axis of depression bar 8 coincides mutually with the axis of recess 3, and the bottom of depression bar 8 is middle convex triangle-shaped structure, and its middle bulge is the circular arc transition. An upper protection plate 9 made of soft material is arranged at the bottom of the compression bar 8. The upper surface of the rotation block 6 is provided with a lower protection plate 10 made of a soft material.
The utility model discloses a theory of operation is: during the use, place pipe fitting 4 in recess 3, realize the spacing to pipe fitting 4 both ends through the length of recess 3, pipe fitting 4 shelves the upper surface at two rotatory pieces 6, and every rotatory piece 6 can use pivot 5 to rotate to the upper surface for the horizontality as the center, and the lower part lug 7 of rotatory piece 6 this moment is not inconsistent with the diapire of recess 3. With the downward movement of the upper die 2, when the bottom of the pressure lever 8 is in contact with the pipe fitting 4, the bottom of the pressure lever 8 applies pressure to the middle of the pipe fitting 4, the two rotating blocks 6 gradually rotate to the state shown in fig. 1 due to the pressure, and the pipe fitting 4 is bent at this time. Although the upper protection plate 9 and the lower protection plate 10 are made of soft materials, when the upper die 2 and the lower die 1 are pressed, the upper protection plate 9 and the lower protection plate 10 are also deformed correspondingly, so that the pipe fitting 4 is sunk between the upper protection plate 9 and the lower protection plate 10, and the surface protection effect on the pipe fitting 4 is achieved. It has not only realized bending to small-size pipe fitting 4, can also avoid 4 surfaces of pipe fitting to receive the damage, and the angle of bending of control that moreover can be accurate has guaranteed the quality of product.
The above-mentioned embodiments are merely illustrative of the principles and effects of the present invention, and some embodiments may be used, and are not intended to limit the present invention; it should be noted that, for those skilled in the art, without departing from the inventive concept, several variations and modifications can be made, which are within the scope of the present invention.
