Description
Technical field
The utility model relates to a bulging mould, particularly a kind of novel bulging mould that can ensure swollen mouth quality.
Background technology
Bulging mould the bore of tubular workpiece can be increased, its structural principle be a diminished shaft when lengthwise movement, the radially outward circumferencial direction of multiple swollen lobe along diminished shaft under the promotion of diminished shaft be positioned at outside diminished shaft moves, and is swollen by the bore of workpiece.But traditional bulging mould in use often exists following problem: between the circle formed due to multiple swollen lobe and diminished shaft and decentraction, therefore cause the mouth of pipe ovalize after swollen mouth; In addition in above-mentioned motion process, often relatively rotate between swollen lobe and diminished shaft, cause swollen mouth size unstable.Therefore now a kind of novel bulging mould that can solve the problem is needed.
Summary of the invention
The utility model is the above-mentioned deficiency in order to solve existing for prior art, proposes a kind of structure simple, designs ingenious, can ensure the novel bulging mould of swollen mouth quality and dimensional stability.
Technical solution of the present utility model is: a kind of novel bulging mould, comprise oil cylinder 1, it is characterized in that: on the working end of described oil cylinder 1, be provided with diminished shaft 2, what match outside the top tapered section of diminished shaft 2 is provided with 8 at circumferentially equally distributed swollen lobe 3, the bottom of swollen lobe 3 is positioned at disk 4 and can at the footpath upward sliding of disk 4, the bottom of disk 4 is fixedly connected with the concentric ring 5 coaxial with disk 4, concentric ring 5 is socketed in outside diminished shaft 2, guide pin bushing 6 is also provided with in the bottom of disk 4, in guide pin bushing 6, slip cap is connected to guide pillar 7, the bottom of this guide pillar 7 is fixedly installed on connecting plate 8, connecting plate 8 is fixedly connected with diminished shaft 2.
Compared with the existing technology, tool has the following advantages the utility model:
The bulging mould of this kind of version, its structure is simple, designs ingenious, rationally distributed.The variety of problems that it highlights in the course of the work for traditional bulging mould, design a kind of special bulging mould structure, it adds this structure of concentric ring on the basis of traditional bulging mould, concentric ring can ensure multiple swollen lobe formed circle with diminished shaft between axiality; And it also increases a set of can the guide pin bushing of relative sliding and guide pillar, utilize guide pin bushing guide pillar structure to prevent from, between diminished shaft with swollen lobe, relative transmission occurs, and then ensure swollen mouth quality.And the manufacture craft of this bulging mould is simple, and cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.As shown in Figure 1: a kind of novel bulging mould, comprise oil cylinder 1, the working end of oil cylinder 1 is provided with diminished shaft 2, conical section on diminished shaft 2 top is associated is outward provided with 8 swollen lobes 3, these are swollen, and lobe 3 is circumferentially being uniformly distributed, with surround a circle, by the conical section of diminished shaft 2 cover wherein, the bottom of swollen lobe 3 is positioned at disk 4, and swollen lobe 3 can radially sliding along disk 4 in disk 4, the bottom of disk 4 is fixedly connected with concentric ring 5, the circle that namely this concentric ring 5 and disk 4(are formed with 8 swollen lobes) axis coinciding, and described concentric ring 5 is also socketed in outside diminished shaft 2, diminished shaft 2 can and concentric ring 5 between relative sliding, also be provided with guide pin bushing 6 in the bottom of disk 4, in this guide pin bushing 6, slip cap is connected to guide pillar 7, and the bottom of this guide pillar 7 is then fixedly installed on connecting plate 8, and connecting plate 8 then with between diminished shaft 2 is fixedly connected with.
The course of work of the novel bulging mould of the utility model embodiment is as follows: when needing to carry out swollen mouth process to the bore of workpiece, oil cylinder 1 works, diminished shaft 2 is driven to move upward, along with diminished shaft 2 and the continuous increase of the diameter of swollen lobe 3 contact portion, the excircle direction motion of 8 swollen lobes 3 one disk 4 in the same way, namely the bore being enclosed within the workpiece outside swollen lobe 3 is swollen; In the above-mentioned course of work, circle because namely the axis of the concentric ring 5 be fixedly connected with bottom disk 4 is formed with 8 swollen lobes with disk 4() axis overlap, and the axis of concentric ring 5 overlaps with the axis of diminished shaft 2, this ensures that there the axiality between circle that diminished shaft 2 and swollen lobe formed, and then ensure swollen mouth quality, prevent the situation of oval swollen mouth; And due to the existence of guide pin bushing 6 and guide pillar 7, in the process that diminished shaft 2 moves, cannot relatively rotate between diminished shaft 2 and swollen lobe 3, effectively can ensure the dimensional stability of swollen mouth.
