Description

A stamping die for an elbow joint

technical field

The utility model belongs to the field of processing elbow joints, in particular to a stamping die for elbow joints.

Background technique

When processing pipe bends in the current industry, hydraulic pipe bending machines or rounding machines are generally used to complete the processing. The hydraulic pipe bending machine completes a pipe bending, and it takes about 10 seconds from clamping to removal. The rounding machine completes a pipe bending. It takes longer time, low work efficiency, high manual labor intensity, and because the operator is standing all the way.

Contents of the invention

In order to overcome the disadvantages mentioned above, the purpose of this utility model is to provide an efficient, fast and convenient stamping die.

The utility model provides a stamping die for an elbow joint, which is characterized in that it comprises a stamping die and a clamping and positioning mechanism. The ejector block on the seat and the first and second rotating dies located on both sides of the ejector block, the first and second rotating dies are movably connected with the lower die base, and the clamping and positioning mechanism includes The regulating and positioning mechanism on the lower mold base and the movable die on the ejector plate, the regulating and positioning mechanism is connected with the first and second rotating dies, and the movable die is arranged on the ejector plate. A die, the movable die is arranged between the first and second rotating dies.

The punch is provided with a groove matching the outer diameter of the pipe fitting;

The rotating die is provided with a groove matching the outer diameter of the pipe;

The movable die is provided with a groove matching the outer diameter of the pipe.

In the utility model elbow stamping die with the above structure, since the lower mold base is provided with an adjustable positioning mechanism, the pre-bending R position of the pipe can be adjusted freely; There is a groove matching the outer diameter of the pipe fitting, so that the pipe fitting is difficult to deform at the moment the pipe is bent, so as to meet the ellipticity requirements of the elbow joint.

Compared with the prior art, the utility model has the advantages of:

The utility model bending pipe stamping die, when processing the bending pipe, can complete the pipe bending process through the punching machine, and the processing of the bending pipe can be completed once the mold is installed, and the whole process only takes 3-4 seconds, which greatly improves the work efficiency. The manual labor intensity is reduced, and the operator sits during the whole operation. The mold structure is simple and the design is reasonable, which can fully meet the ellipticity requirements of the elbow joint, and is suitable for mass production.

Figure 2 is a schematic structural diagram of the right view of the mold of a specific embodiment of the utility model.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1 and Figure 2, the elbow joint stamping die of the present utility model includes an upper die base (1), a punch (2), a rotating die (3) left and right, and a top plate ( 4), the lower mold base (5). The punch (2) is provided with an annular groove matching the outer diameter of the pipe fitting (10). The rotary die (3) is provided with a groove matching the outer diameter of the pipe fitting (10). The lower mold base (5) is provided with a regulating and positioning mechanism (5-1). An indispensable movable die (4-1) is provided on the top material plate (4). The movable die (4-1) is provided with a groove matching the outer diameter of the pipe fitting (10).

In the stamping die of the utility model elbow joint with the above structure, since the control and positioning mechanism is set on the lower mold base (5), the pre-bending R position of the pipe fittings can be freely adjusted; since the ejector plate (4) is equipped with an indispensable movable concave mold (4-1), and the movable die (4-1) is provided with a groove matching the outer diameter of the pipe fitting (10), so that it is difficult for the pipe fitting to deform at the moment the pipe bends, so as to achieve the Its ellipticity requirements. After the mold is installed, the processing of the bent pipe can be completed, and the whole process only takes three or four seconds, which greatly improves the work efficiency and reduces the labor intensity of the operator.

As a modification of the utility model, the shape and size of the grooves of the punch (2), the rotating die (3) and the movable die (4-1) are determined according to the shape of the pipe fitting (10).

The utility model is not limited to the above-mentioned embodiments, regardless of any changes in the size, length, and pre-bending R position of the utility model, any use of the above-mentioned bent pipe stamping die is a deformation of the utility model, and should be considered as Within the protection scope of the utility model.
