FIG. 1 is a schematic structural diagram of a die for forging shaft parts, which is provided in the embodiment;
FIG. 2 is a partial sectional view showing the mold clamping in the embodiment.
Detailed Description
Referring to fig. 1-2, the present invention provides a die for forging shaft parts, which includes an upper die base 1, a lower die base 2, an upper die block 3, a lower die block 4, and two side die blocks 5. Wherein: the upper die holder 1 can be directly connected with the forging hammer 14 or arranged below the forging hammer 14, and the lower die holder 2 can be fixed on the forging table. The upper module 3 is fixedly arranged on the upper die base 1 in a detachable mode, the lower module 4 is fixedly arranged on the lower die base 2 in a detachable mode, the upper module 3 and the lower module 4 are opposite up and down, the two side modules 5 are arranged between the upper die base 1 and the lower die base 2, and the two side modules 5 are opposite left and right.
The outer sides of the two side modules 5 are provided with first inclined planes 6, the upper die base 1 and the lower die base 2 are provided with second inclined planes 7, the inclined angles of the first inclined planes 6 and the second inclined planes 7 are preferably 45 degrees, and the second inclined planes 7 are matched with the first inclined planes 6 of the side modules 5 and used for driving the two side modules 5, the upper die block 3 and the lower die block 4 to be gathered and assembled when the upper die base 1 and the lower die base 2 move in opposite directions.
The inner sides of the upper module 3, the lower module 4 and the side module 5 are all provided with circular arc concave surfaces 8, the circular arc concave surfaces 8 of the modules are encircled to be circular when the modules are assembled, and the arc lengths of the circular arc concave surfaces 8 of the modules are preferably equal.
The die can be used for forging shaft parts, when forging, the forging hammer 14 presses the upper die base 1 downwards to enable the upper die base 1 and the lower die base 2 to move oppositely and extrude the side die block 5, downward pressure can be converted into thrust for laterally pushing the side die block 5 under the action of an inclined plane, the side die block 5 moves inwards synchronously, and therefore all the die blocks are gathered together to forge and press parts from all directions simultaneously.
Because each module forges and presses parts from a plurality of directions in step, can prevent that the part from producing great deformation in each stress surface clearance to can forge the part into the circle more fast, more simply. On the other hand, the round shape formed by the die assembly of each module is the final size and shape of the part, so that the part forming effect is good.
In a further embodiment, the first inclined surface 6 of the side module 5 is provided with a slide block 9, the second inclined surface 7 is provided with a slide groove 10, the side module 5 is slidably matched with the slide groove 10 through the slide block 9, and the slide groove 10 is preferably a dovetail-shaped slide groove 10. The sliding groove 10 is used for connecting the side die block 5 with the upper die base 2 and the lower die base 2 together, so that the two side die blocks 5 can synchronously move outwards when the upper die base 1 ascends, reciprocating motion forging and pressing of parts is facilitated, and the parts are conveniently separated from the die blocks when the parts are loaded and unloaded.
In some embodiments, guide posts 11 are vertically fixed on two sides of the lower die holder 2, the upper die holder 1 is slidably mounted on the guide posts 11, and the guide posts 11 can improve the die assembly accuracy of the die.
The guide post 11 is sleeved with a pressure spring 12, and the pressure spring 12 is used for jacking the upper die holder 1 upwards through elasticity. The upper end of the guide post 11 is connected with a limit nut 13 through threads.
It is necessary to provide the pressure spring 12 for lifting up the upper die holder 1 when the upper die holder 1 is placed below the hammer 14 without being connected to the hammer 14. When the forging hammer 14 moves upwards, the pressure spring 12 can drive the upper die holder 1 to reset upwards, so that each module is separated to generate a punching end space; the compression spring 12 also provides a shock absorbing effect when the hammer 14 is depressed, thereby providing a protective effect.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
