Abstract
The utility model discloses a composite hole thermal forming die, belongs to the technical field of machining manufacture, comprises a punch and is characterized in that the punch comprises a handle end and a head end from top to bottom, and a reversed frustum-shaped protrusion of the punch is arranged at the middle position of the punch. The punch of the composite hole thermal forming die is in an integral structure, thereby enabling the head end of the punch to be punched out of the lower end of a composite hole. The top end inclined surface of the composite hole extruded by the reversed frustum-shaped protrusion is dislocated, the needed composite hole can be processed by only one device in one punching. The shape of processed composite hole is completely identical with that of the fallen punch, quality can be controlled, production efficiency is greatly improved, and production cost is effectively reduced.
Description
Technical field
The utility model belongs to machining manufacturing technology field, is specifically related to a kind of composite holes hot forming tool.
Background technology
In industrial production, the processed and applied in hole is very extensive, and wherein some is a composite holes, promptly has faulting of slab ends in the hole, and this sedimentation faulting of slab ends is the most difficult with the processing of inclined-plane sedimentation.At present, the work point two procedures that adds of this composite holes is carried out: first procedure bit drills aperture, and second operation work is processed inclined-plane sedimentation platform with larger-diameter drill bit, and this processing method need take two equipment and carry out twice boring of priority, take a lot of work, time-consuming, and the relative position of twice boring is difficult for controlling, and the composite holes axiality that processes is low, and is not accurate, meanwhile, the inside, aperture that bore process processes is comparatively coarse, when the aperture hour, also be difficult for carrying out grinding-polishing.
The utility model content
Technical problem to be solved in the utility model provides a kind of composite holes hot forming tool, makes once precisely machine-shaping of composite holes.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of composite holes hot forming tool is provided, comprises drift, drift is divided into pommel and head end two parts from top to bottom successively, at the drift middle part inversed taper platform shape projection is set.
In the utility model, also comprise counterdie, counterdie is provided with the through hole that matches with the head end of drift.Counterdie working face be the inclined plane.The pommel of drift is back taper.Also comprise drift cover for seat and locking nut, the pommel of described drift is fixed in the drift cover for seat by locking nut.Punch holder puts offers bolt hole.The quantity of bolt hole is at least three.
The beneficial effects of the utility model are:
1, because drift is divided into pommel and head end two parts from top to bottom successively, at the drift middle part inversed taper platform shape projection is set, can make the head end of drift go out the lower end of composite holes, inversed taper platform shape projection squeezes out inclined-plane, the top faulting of slab ends of composite holes, only need an equipment, a punching press just can process needed composite holes, and the composite holes that processes is identical, quality controllable with the shape that falls the drift part.
3, on counterdie, be provided with the through hole that matches with the head end of drift, only allow the material at institute punching position to fall, guarantee that the periphery of position, hole is not damaged.
4, since counterdie working face be the inclined plane, fill the workpiece slope angle with the slope of counterdie, drift compensation sliding force can be processed the workpiece that has bevel angle, formed precision is higher.
5, the pommel of drift is fixed in the drift cover for seat by locking nut, assists to realize the installation of drift, and is convenient for changing drift.
6, put in punch holder and be provided with the bolt hole that is connected with punch press, the quantity of bolt hole is at least three, realizes that drift simple on punch press firmly install.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1, head end, 2, projection, 3, pommel, 4, the drift cover for seat, 5, bolt hole, 6, locking nut 7, counterdie, 8, through hole, 9, working face, 10, drift.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.
In the utility model, drift 10 that end that elder generation contacts with surface of the work when working is defined as the bottom or the lower end of drift.
As shown in Figure 1, in the composite holes hot forming tool that is provided, drift 10 is an integral structure, drift 10 is divided into pommel 3 and head end 1 two parts from top to bottom successively, be provided with inversed taper platform shape projection 2 at drift 10 middle parts, realize the precisely angle transition between the hole up and down of composite holes, and strengthened the intensity of drift 10.The pommel 3 of drift 10 is back taper, the pulling force that the pommel of the drift 10 of being convenient to distribute 3 is suffered.On counterdie 7, be provided with the through hole that matches with head end 1 bottom of drift 10, be convenient to go out high-quality composite holes.Counterdie 7 end face be working face 9, working face 9 is designed to the inclined plane, is convenient to fixedly that the bottom surface is the workpiece on inclined plane, and accurately punching on this workpiece.The pommel 3 of drift 10 is fixed in the drift cover for seat 4 by locking nut 6, and drift cover for seat 4 is provided with the bolt hole 5 that is connected with punch press, and the quantity of bolt hole 5 is four, the installation of simple realization drift 10 on punch press, and be convenient to the installation and the replacing of drift 10.
During use, the pommel 3 of drift 10 is inserted in the drift cover for seat 4, with locking nut 6 the two is locked, by at least three bolts drift cover for seat 4 is connected on the punch press then, again counterdie 7 is installed on the punch press workbench of drift 10 belows, just passes the through hole of counterdie 7 when the head end 1 of drift 10 is fallen.
During the processing composite holes, workpiece after the heating is positioned on the counterdie 7, press the punch press run switch, punch press drives the bottom that drift 10 is gone out the composite holes that the head end 1 with drift 10 matches downwards, boss 2 squeezes out the top of composite holes, thereby makes a standard moulding of composite holes, production efficiency height, if the processing plane workpiece, then select for use end face be the plane counterdie 7.
It is to be noted; above-mentioned embodiment only is the utility model preferred embodiment; for those skilled in the art, under the prerequisite that meets the utility model operation principle, any be equal to or similar replacement all falls in the protection domain of the present utility model.
