The utility model discloses can directly dash out the axial hole of axostylus axostyle part when cold-heading axostylus axostyle part to realize the smooth drawing of patterns of axostylus axostyle part.
Description
Technical Field
The utility model relates to a cold-heading mould, concretely relates to cold-heading mould that area punched a hole.
Background
At present, the axial hole of the shaft rod part with the axial hole is difficult to be formed by directly cold upsetting by using a cold upsetting die, and the punch used for punching after punching can be inserted into the shaft rod part, so that the shaft rod part cannot be smoothly demoulded, and particularly, the axial hole with deep depth is formed.
Disclosure of Invention
The utility model aims to provide a not enough to prior art, the utility model aims at providing a can be in the axial hole of direct punching out axostylus axostyle part of cold-heading axostylus axostyle part to realize the area cold-heading mould that punches a hole of the smooth drawing of patterns of axostylus axostyle part.
The utility model discloses a realize through following technical scheme:
area cold-heading mould that punches a hole, including mould and fixed lower mould in the punching press, the mould is made activity setting from top to bottom in the punching press, its characterized in that: the punching upper die is provided with an upper die cavity, the fixed lower die is provided with a lower die cavity, a punching ejector rod is inserted into the lower die cavity and movably arranged up and down, the upper rod end of the punching ejector rod is provided with a left half punch and a right half punch which are axially separated from the middle, the left half punch is independent of the punching ejector rod, the right half punch is fixedly connected with the punching ejector rod, the left half punch and the right half punch can move up and down relatively, the inner side surface of the left half punch is provided with a lower limiting step, the inner side surface of the right half punch is provided with an upper limiting step, the bottom of the lower die cavity is provided with a guide hole, and the guide hole guides the up and down movement of the left.
Above-mentioned technical scheme's area cold-heading mould that punches a hole, when the appearance of shaping play axostylus axostyle part through upper and lower die cavity cold-heading, can utilize the axial hole of the left half drift and the right half drift of the ejector pin upper rod end that punches a hole direct forming play axostylus axostyle part, then after the shaping is accomplished, when punching press the mould return, the ejector pin that punches a hole upwards moves the lower die cavity of the ejecting fixed lower mould of axostylus axostyle part, the axostylus axostyle part is carried by cold-heading machine's clamp, the ejector pin return that punches a hole after that, the right half drift is at first left the axial hole of axostylus axostyle part, after the right half drift moves certain distance downwards, the contact pulling left half drift of left side of the contact pulling of spacing.
Preferably, when the heights of the tops of the left half punch and the right half punch are the same, the bottom surface of the left half punch is abutted against the top surface of the punching ejector rod, and the distance between the lower limiting step and the upper limiting step is smaller than the punching depth.
Drawings
The utility model discloses there is following figure:
figure 1 is a schematic structural diagram of the present invention,
figure 2 is the utility model discloses the fashioned work piece of cold-heading.
Detailed Description
As shown in figure 1, the cold heading die with punching hole of the utility model comprises an upper punching die 1 and a fixed lower die 8, the upper punching die 1 is movably arranged up and down, the upper punching die 1 is provided with an upper die cavity 2, the fixed lower die 8 is provided with a lower die cavity 3, a punching mandril 7 is inserted into the lower die cavity 3, the punching mandril 7 is movably arranged up and down, the upper rod end of the punching mandril 7 is provided with a left half punch 9 and a right half punch 4 which are separated from the middle in the axial direction, the left half punch 9 is independent of the punching mandril 7, the right half punch 4 is fixedly connected with the punching mandril 7, the left half punch 9 and the right half punch 4 can move up and down relatively, the inner side surface of the left half punch 9 is provided with a lower limit step 10, the inner side, the bottom of the lower die cavity 3 is provided with a guide hole 6, and the guide hole 6 guides the up-and-down movement of the left half punch 9 and the right half punch 4 together; when the heights of the tops of the left half punch 9 and the right half punch 4 are the same, the bottom surface of the left half punch 9 is abutted against the top surface of the punching ejector rod 7, and the distance between the lower limiting step 10 and the upper limiting step 5 is smaller than the punching depth. The structure of the shaft lever part with the axial hole formed by cold heading of the utility model is shown in figure 2.
