Description
Technical field
The present invention relates to a kind of shaped device, relate in particular to a kind of forming apparatus for forming pipe end.
Background technology
The function of automatic pipe reducing machine mainly is the processing and forming of the one or both ends of tubing being carried out various patterns, and the pipe end forming mechanism in the automatic pipe reducing machine is exactly to one of vitals of pipe end processing and forming.The parts of traditional shaping mechanism mainly comprise: saddle, match with the slide block of a dovetail groove in the front portion of saddle; The another side of slide block is installed with several die holders, and the die change oil cylinder is installed on the sidewall of saddle, and the die holder that the piston rod of die change oil cylinder can drive on the dovetail slide block moves around at saddle; Master cylinder is installed on the oil cylinder fixing base; The leading section of main oil cylinder piston bar is connected with saddle, and piston rod can drive the die holder feeding of saddle and retreat.The operation principle of the shaping mechanism of said structure is: at first install respectively required mould on each die holder, then start the die change oil cylinder, the pipe-reduction mold of the first station is aimed at the front end that is fixed on the pipe to be processed on the clamp support, that is: make this mould be in the operating position, restart the master cylinder that is installed on the oil cylinder fixing base, the piston rod of master cylinder drives whole saddle and slides at T-shaped groove, push the mould on the first station die holder to pipe to be processed, and by the end of this mould extruding pipe, thereby finish first processing and forming operation to tube end; Then the reverse starting master cylinder makes saddle in the reverse slip of T-shaped groove, makes the mould of the first station return the home position; Then restart the die change oil cylinder, the mould on the second station die holder is aimed at the end of pipe to be processed, the process under connecing is identical with the process of the first station; Until finish the moulding of tube end is all processed.The shortcoming of the shaping mechanism of said structure is: because the die holder of each station all is installed on the dovetail slide block successively, the action that realizes next station all needs the die change oil cylinder to promote, if the Pipe forming arts demand 4-5 station that has or 5 just can finish more than the station, the width of that saddle and dovetail slide block will be followed increasing of die holder and be widened, and the structure that the die change piston rod also will lengthen and need to make segmented could realize the die change of multistation; Like this, the words that self quality of saddle is added the weight of a plurality of die holders and die change oil cylinder are far longer than the weight of the machine for shrinking of single station or double, thereby increase one's load for master cylinder drives saddle, and effect is slack-off; The manufacturing processing cost of equipment can be very high, the equipment configuration design brings unusual inconvenience to operating personnel, the design of this equipment is less-than-ideal to the product with a plurality of station moulding of processing, can only carry out some simple pipe end moulding, and certain limitation is arranged.
Summary of the invention
