Description

A kind of Novel elbow pipe enlarging flange die
Technical field
The utility model belongs to the enlarging technology in Machining Technology field, is specially a kind of Novel elbow pipe enlarging flange die for automobile exhaust muffler pipe bend pipe enlarging flange.
Background technology
In existing auto manufacturing technology; in in its tailpipe, often can use a joint or more piece bend pipe structure; this bend pipe structure is generally independent moulding; its tube manufacture complex forming technology; step is many; and because rear portion needs to be connected with other parts, need to carry out enlarging at the marginal position place at two, make enlarging place than original internal diameter more greatly.
And the manufacture craft of the pipe fitting of this class comprises the multiple working procedures such as bend pipe, pipe-expanding machine enlarging and flanger flange, wherein, in bend pipe enlarging and flanging process, because its front end workpiece original paper is bend pipe, add on pipe fitting sidewall and have seam seam, while carrying out punching operation in traditional moulds, the parcel of pipe fitting is poor, make it in enlarging and turn-up process, easily split in seam seam position, thereby percent defective is also higher.Meanwhile, owing to reckoning without the preformed stage of flanging process in enlarging technique, when flange, also need the pipe fitting after enlarging to carry out pre-flange, thereby in the situation that having increased this procedure, the production efficiency of whole production line has also reduced.
Utility model content
The technical problem that the utility model solves is to provide a kind of Novel elbow pipe enlarging flange die, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of Novel elbow pipe enlarging flange die, comprise patrix and counterdie, wherein, between described patrix and counterdie, be provided with two station grooves, in two station grooves, include and be fixed in putting material seat and being fixed in the processing seat on patrix on counterdie, the described material seat put comprises two square base unit, and in the junction of two square base unit, has the hopper of putting with workpiece to be processed consistent size; On described top processing seat, be fixed with two groups of multistage cylindricality punch of different structure, this punch is over against the slotted eye position of putting hopper of putting in material seat, and in these two groups of punch, include guiding rank and enlarging rank, simultaneously, the rear portion, enlarging rank of a punch is provided with a pre-flange oblique band therein, and the rear portion, enlarging rank of another one punch is flange rank.
In the utility model, the both sides of described processing seat are provided with sliding shoe and sliding shoe drive unit, drive sliding shoe to realize put the restriction of expecting square base cell position in seat by sliding shoe.
In the utility model, the cross section size on described guiding rank is less than the internal diameter of pipe fitting to be processed, to facilitate to utilize, punch is positioned.
In the utility model, the cross section size on described enlarging rank is consistent with the internal diameter of finished parts.
In the utility model, the axial slices of described pre-flange oblique band is a trapezium structure, and the angle of its hypotenuse and vertical plane is 15 ~ 20 °.
In the utility model, the cross section size on described flange rank is greater than the outside dimension of the body at flange place.
In the utility model, between between described guiding rank and enlarging rank and enlarging rank and pre-flange oblique band, be smooth arc-shaped transition.
In the utility model, between described patrix and counterdie, be provided with independently guide pillar structure, to guarantee the perpendicularity in patrix stroke, to improve machining accuracy.
Beneficial effect: the utility model is in process; by putting material seat, treat processing pipe fitting parcel property and fix; can effectively improve the stability of workpiece to be processed in process; and its surface is protected; and pre-flanging process under pre-flange oblique band structure can effectively reduce the workload of overturning process; and the global formation quality of body after improving after flange; simultaneously; utilize the rotation of two machining position; can effectively reduce the degree of wear of mould, improve continuity and the operating efficiency of its processing, in cost-saving, die cavity maintenance and replacing are more convenient.
Accompanying drawing explanation
