The purpose of this utility model is exactly will overcome in the traditional moulding process that has the circular hole flange now to exist because of device-restrictive accessory size to be processed, cause large-scale workpiece can only adopt partial cut to carry out the defective of circular hole flange processing, a kind of heavy parts partial circle hole flanging shaped device is provided.It is simple in structure, easy operating, economical and practical, circular hole flange processing effect is good; Need not cutting, can be directly to the large-scale workpiece part carrying out the processing of circular hole flange.
For achieving the above object, the heavy parts partial circle hole flanging shaped device that the utility model is designed, it comprises punch and die, be separately positioned on during work and treat flange bottom outlet both sides on heavy parts, its special character is: the axle center of punch is provided with the punch hole, and the axle center of die is provided with die hole; It also comprises pull bar and hydraulic gun; The head of pull bar is provided with boss, and the afterbody of pull bar is provided with annular groove, and during work, pull bar passes punch hole and die hole, and the boss of pull bar is close to the bottom of punch; Hydraulic gun has the hydraulic pressure gun platform and moves axially with it hydraulic chuck that coordinates, during work, the hydraulic pressure gun platform is pressed on the bottom of die, hydraulic chuck by the matched moulds of punch and die, thereby will treat that the flange bottom outlet is processed as the moulding flanging bore with the annular groove clamping of pull bar and pull and coordinate.
Further, adopt thread matching structure between the annular groove of described pull bar afterbody and hydraulic chuck.Like this, can guarantee the stability that pull bar is connected with hydraulic chuck, also can guarantee axiality, avoid occurring error.
Again further, adopt matched in clearance or interference fits structure between described pull bar and punch hole and die hole.Like this, can keep the axiality of punch and die motion, guarantee the accuracy of matched moulds.
The utility model has the advantage of: designed heavy parts partial circle hole flanging shaped device can solve a heavy parts partial circle hole flanging moulding process difficult problem, add and not limited by place and accessory size, according to the processing needs, movable hydraulic rifle, die and punch get final product.Simultaneously, the utility model is simple in structure, process economics, circular hole flange processing effect are good, can be directly the processing of circular hole flange be carried out in the large-scale workpiece part, cuts down finished cost, and saves process time.
Description of drawings
Fig. 1 is that a kind of heavy parts partial circle hole flanging shaped device is at the structural representation of part original state.
Fig. 2 is that heavy parts partial circle hole flanging shaped device shown in Figure 1 is at the structural representation of forming parts state.
In figure: pull bar 1(wherein: boss 1.1, annular groove 1.2), die 2(wherein: die hole 2.1), punch 3(wherein: punch hole 3.1), heavy parts 4(wherein: treat flange circular hole 4.1, moulding flanging bore 4.2), hydraulic gun 5(wherein: hydraulic chuck 5.1, hydraulic pressure gun platform 5.2).
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Heavy parts partial circle hole flanging shaped device shown in figure comprises punch 3 and die 2, pull bar 1 and the hydraulic gun 5 of paired setting.The axle center of punch 3 is provided with punch hole 3.1, and the axle center of die 2 is provided with die hole 2.1, and during work, punch 3 and die 2 are separately positioned on the both sides for the treatment of flange bottom outlet 4.1 on heavy parts 4.The head of pull bar 1 is provided with boss 1.1, the afterbody of pull bar 1 is provided with annular groove 1.2, adopt matched in clearance or interference fits between pull bar 1 and punch hole 3.1 and die hole 2.1, during work, pull bar 1 passes punch hole 3.1 and die hole 2.1 successively, and the boss 1.1 of pull bar 1 is close to the bottom of punch 3.Hydraulic gun 5 has hydraulic pressure gun platform 5.2 and moves axially with it hydraulic chuck 5.1 that coordinates, and during work, hydraulic pressure gun platform 5.2 is pressed on the bottom of die 2, and 5.1 annular grooves 1.2 with pull bar 1 afterbody of hydraulic chuck are threaded and pull and coordinate.
