Flanging mold for side hole of similar pipe fittings.

For this reason, the utility model adopts the following technical solutions: a new type of cylindrical pipe fitting side hole flanging die, including a punch and a die, a discharge device and a bottom plate that cooperate with each other, and the die is installed on a pressure plate through a die handle. Among the sliders on the machine, the punch is installed on the workbench of the press, the pipe fittings are supported and positioned on the bottom plate by the support mechanism, and the unloading device drives the pipe fittings to realize unloading.

As a supplement and improvement to the above technical solution, the utility model also includes the following technical features.

The discharge device includes a discharge return device, a return pin and a discharge plate, the discharge return device is fixed on the bottom of the bottom plate, one end of the return pin is connected to the discharge return device, The other end of the return pin is connected to the stripper plate, and the pipe fitting is located at the top of the stripper plate.

The upper end of the stripping plate forms an arc-shaped groove for accommodating the pipe fittings, thereby facilitating the pipe fittings to be accommodated.

The support mechanism includes a pressing plate, a vertical plate and a supporting plate, the vertical plate and the supporting plate are respectively arranged at both ends of the top of the bottom plate, and a working chamber for accommodating the discharge plate and the pipe is formed between the vertical plate and the supporting plate, The pipe fittings are supported on the riser and the supporting plate, and the pressing plate is arranged on the riser.

The punch is an integral structure.

The utility model uses the concave mold of the press to go down, and the workpiece is formed at one time. After forming, the material is unloaded and taken out through the unloading plate and the unloading return device, and the operation is convenient and fast.

Using the utility model can achieve the following beneficial effects: the utility model is convenient to operate, fast in forming and improved in efficiency. The utility model realizes the forming of the workpiece by adjusting the stroke of the press, which can reduce the number of forming times compared with hydraulic bulging and soft mold bulging, and the efficiency is also greatly improved compared with hydraulic bulging and soft mold bulging, and the installation and adjustment are also more convenient.
