Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Example (b):
as shown in fig. 1 and fig. 2, a high-strength fluted disc forming die comprises a die body 1, a cavity 11 and a shaft sleeve 12. The cavity 11 is opened on the surface of the die body 1; the shaft sleeve 12 is fixed in the middle of the die body 1, and the shaft sleeve 12 and the die body 1 are coaxially arranged. The shaft hole 2 is formed inside the sleeve 12.
A supporting column 3 penetrates through the shaft hole 2, and a positioning concave hole 31 is formed in the outer wall of the supporting column 3; the inner wall of the shaft hole 2 is fixed with a spring plate 4. The spring plate 4 is made of spring steel. The middle shaft hole 2 of the spring plate 4 is bent to form a convex part 41, and the convex part 41 is positioned in the shaft hole 2. When the support pillar 3 is inserted into the shaft hole 2, the protrusion 41 is fitted into the positioning concave hole 31.
When the shaping, at first penetrate the bolt in the fixed orifices 13 of die body 1, screw up the bolt, fix die body 1 on the workstation, insert support column 3 in shaft hole 2, pour into molten metal or add softened shaping material into the die cavity 11 again, operate stamping machine afterwards, make the clamp plate (movable mould) of die body 1 top begin to push down, the clamp plate is with the compaction of the shaping material in the die cavity 11, the clamp plate rises afterwards, has just formed fashioned fluted disc in the die cavity 11.
When polishing, the mould is transferred to the polishing platform, the support column 3 is taken out, the rotating shaft penetrates through the shaft hole 2 and the mould and the rotating shaft are relatively fixed, the rotating shaft rotates, meanwhile, the polishing stone is in contact with the formed fluted disc in the cavity 11, the fluted disc is polished and polished, burrs are removed, and the surface brightness of the fluted disc is improved.
Because in the pressurization process, support column 3 has been inserted in axle sleeve 12, support column 3 plays the effect of providing extra supporting force, the holding power that support column 3 provided is opposite with the direction of the extrusion force of shaping material to axle sleeve 12, and the holding power can offset part shaping material to the extrusion force of axle sleeve 12, thereby the external force that makes axle sleeve 12 self receive reduces, the compressive strength of axle sleeve 12 has been improved, prevent that axle sleeve 12 pressurized from warping, ensure the precision of die cavity 11, thereby the shaping precision of fluted disc has effectively been ensured.
In the process that the support column 3 penetrates into the shaft hole 2, the convex part 41 is embedded into the positioning concave hole 31, and the generated friction force realizes the positioning of the support column 3; the supporting column 3 is pulled in the direction far away from the shaft hole 2, so that the convex part 41 can be separated from the positioning concave hole 31, the separation of the supporting column 3 and the shaft sleeve 12 is realized, and the operation is simple and convenient.
One end of the support column 3 close to the shaft sleeve 12 is provided with a guide inclined plane 5. The support column 3 is easily inserted into the shaft hole 2 by the guiding action of the guide slope 5.
The one end that the support column 3 kept away from guide inclined plane 5 has been seted up and has been placed recess 6, and the opening part of placing recess 6 is fixed with the pull rod 61 that is the L shape setting. Because the frictional force between protruding portion 41 and the location shrinkage pool 31 is great, place the recess 6 in through placing the finger to through holding pull rod 61, can be convenient for take out support column 3 from shaft hole 2, easy and simple to handle.
The inner wall of the support column 3 is provided with a weight-reducing concave hole 71. A plurality of reinforcing rods 72 are fixed to the inner wall of the weight-reducing recessed hole 71. Through subtracting the setting of heavy shrinkage pool 71, reduce the quality, the transportation of being convenient for promotes the structural strength of support column 3 through setting up of stiffener 72 simultaneously. Thereby not causing the effect of seriously reducing the structural strength under the condition of reducing the quality.
In order to make the structure of the supporting column 3 more stable, three reinforcing rods 72 are connected in tandem and distributed in a triangular shape. The three reinforcing rods 72 are a group of reinforcing groups, a plurality of groups of reinforcing groups are arranged on the inner wall of the weight-reducing concave hole 71, and the reinforcing groups are arranged along the length direction of the weight-reducing concave hole 71.
