The utility model adopts the technical scheme that the swing arm type shaping device is characterized by comprising a lower die holder, wherein a lower die groove is arranged at the upper end of the lower die holder, a lower die insert is arranged in the lower die groove, the middle part of the upper surface of the lower die insert protrudes upwards to form a workpiece placing part, and guide plates are obliquely arranged on the groove walls at two sides of the lower die insert;

still include the upper die base, inlay on the upper die base and be equipped with two supporting shoes, still be provided with two wobbling rotor arms relatively, the rotor arm is from up passing down the upper die base, and two the upper end of rotor arm corresponds the articulated joint to two the ends of supporting shoe, every the lower part outside border of rotor arm all be provided with the inclined plane of baffle adaptation, two be provided with a plurality of material nitrogen spring of pressing between the supporting shoe, material nitrogen spring passes downwards the upper die base, just material nitrogen spring's lower extreme is provided with the eccentric swage.

Technical scheme more than adopting, the die holder is used for setting up the lower mould and inserts, and the lower mould is inserted and is used for placing the work piece through the work piece portion of placing, and the baffle is used for with the rotor arm adaptation, and then carries out the plastic to the work piece. The upper die base is used for setting up the supporting shoe, and the supporting shoe is used for setting up the rotor arm, and the rotor arm is through with the baffle adaptation, and the slope slides comes to extrude the plastic to the work piece. And the material pressing nitrogen spring presses and shapes the workpiece through the material pressing device.

Further , preferably, in order to enhance the shaping effect, punch inserts are provided on both sides of the work placing part.

Further , preferably, a shaping die insert is provided on the inner side of the lower portion of each of the rotating arms for enhancing the shaping effect.

And , preferably, in order to facilitate the return of the rotating arm, a return spring is connected to the upper part of the rotating arm, and the return spring is arranged on the upper die holder.

, preferably, in order to provide space for the moving of the rotating arm, the upper die base is provided with a rotating arm hole for the rotating arm to pass through, and the width of the rotating arm hole is larger than that of the rotating arm.

Has the advantages that: the utility model discloses think about novelty, design benefit and rational in infrastructure, carry out the plastic through rotor arm and baffle cooperation, be applicable to the narrow and small work piece that the design space is not enough, respond well.

Detailed Description

The present invention will be further described in with reference to the following drawings and examples:

the swing arm type shaping device shown in the figures 1 to 2 is characterized by comprising a lower die base 1, a lower die groove is formed in the upper end of the lower die base 1, a lower die insert 2 is arranged in the lower die groove, the middle of the upper surface of the lower die insert 2 protrudes upwards to form a workpiece placing part 2a, guide plates 3 are obliquely arranged on the groove walls on two sides of the lower die insert 2, an upper die base 4 is further included, two supporting blocks 5 are embedded in the upper die base 4, two swingable rotating arms 11 are oppositely arranged, the rotating arms 11 penetrate through the upper die base 4 from bottom to top, the upper ends of the two rotating arms 11 are correspondingly hinged to ends of the two supporting blocks 5, an inclined surface matched with the guide plates 3 is arranged on the outer side edge of the lower portion of each rotating arm 11, a plurality of material pressing nitrogen springs 6 are arranged between the two supporting blocks, the material pressing nitrogen springs 6 penetrate through the upper die base 4 downwards, and material pressing devices.

The utility model discloses in concrete use, at first place the lower mould 2 insert the work piece place the portion 2a with the work piece on, then drive upper die base 4 down, the outside border and the cooperation of baffle 3 of rotor arm 11 for rotor arm 11 inwards oppresses, has accomplished the plastic to the work piece. In the actual use process, the nitrogen spring 6 pushes the swager 7 to press and shape the workpiece.

In the specific implementation process, as a preferable technical scheme, punch inserts 8 are arranged on two sides of the workpiece placing part 2 a. The contact surface of the punch insert 8 and the workpiece is arranged in a copying manner, so that the pressing and shaping effects are increased.

In the specific implementation, as a preferred technical scheme, the lower inner side of each rotating arm 11 is provided with a shaping die insert 9. The contact surface of the shaping die insert 9 and the workpiece is also arranged in a copying manner, so that the effect of pressing and shaping is increased.

In the specific implementation process, as a preferable technical scheme, the upper part of the rotating arm 11 is connected with a return spring 10, and the return spring 10 is arranged on the upper die holder 4. After the rotating arm 11 finishes reshaping, the return is needed through the return spring 10.

In the specific implementation process, as a preferable technical scheme, the upper die base 4 is provided with a rotating arm hole 4a for allowing the rotating arm 11 to pass through, and the width of the rotating arm hole 4a is larger than that of the rotating arm 11. Since the rotating arm 11 needs to rotate during operation, the width of the rotating arm hole 4a is larger than that of the rotating arm 11, which facilitates the movement of the rotating arm 11.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
