Description
Technical Field
The invention relates to the field of die parts, in particular to a discharging bolt for a material pressing core.
Background
The discharge screw is very common in a stamping die. In use, the discharge screw is used for connecting the upper template and the pressing core and is connected to the press together. When the press machine moves downwards to drive the die to perform stamping, the discharging screw only plays a connecting role, when the press machine moves upwards in a return stroke, the upper die plate moves upwards, and the lower end of the discharging screw collides with the inner bottom surface of the upper part of the material pressing core and then drives the material pressing core to move upwards in the return stroke. The existing unloading bolt has a narrow supporting surface, and the gray iron is easily pressed to be sunken and deformed when the bolt is fastened, so that the size cannot be ensured, and the gray iron is very easy to loosen, so that the problem is solved very importantly.
Disclosure of Invention
The invention aims to provide a discharging bolt for a material pressing core, which adopts a double-sleeve structure to increase a supporting surface and solve the problem of easy deformation and looseness.
The invention provides a discharging bolt used for a material pressing core, which comprises a discharging bolt body, wherein the discharging bolt comprises a nut and a screw rod, the screw rod is connected to the lower side of the nut, a first sleeve is arranged on the outer side of the middle of the screw rod, a first gasket is arranged at the upper end of the screw rod, the upper end of the first sleeve is in contact with the lower side of the first gasket, a second sleeve is arranged on the outer side of the lower end of the first sleeve, a second gasket is arranged in the middle of the first sleeve, the lower side of the second gasket is in contact with the second sleeve.
The further improvement lies in that: the first washer is a steel washer, and the outer diameter of the first washer is larger than that of the nut.
The further improvement lies in that: the second gasket is an elastic gasket.
The further improvement lies in that: the first sleeve is longer than the screw.
The further improvement lies in that: and SS41 is embedded on the gray iron, and the SS41 and the gray iron body are connected through bolts.
The invention has the beneficial effects that: by adopting the double-sleeve structure, the supporting surface is enlarged, the impact force is reduced, and the fracture is not easy to occur; the first gasket reduces abrasion, the second gasket reduces impact, the safety of a product is improved, consumption is reduced, and cost is reduced.

Detailed Description
For the purpose of enhancing understanding of the present invention, the present invention will be further described in detail with reference to the following examples, which are provided for illustration only and are not to be construed as limiting the scope of the present invention.
As shown in fig. 1, this embodiment provides a pressure material bolt that core used, including the bolt body of unloading, the bolt of unloading includes nut 1 and screw rod 2, screw rod 2 is connected at nut 1 downside, the outside is equipped with first sleeve 3 in the middle of the screw rod 2, 2 upper ends of screw rod are equipped with first packing ring 4, 3 upper ends of first sleeve and 4 downside contacts of first packing ring, 3 lower extreme outsides of first sleeve are equipped with second sleeve 5, 3 outsides of first sleeve are equipped with second packing ring 6, 6 downside of second packing ring and 5 upper end contacts of second sleeve, 2 lower extremes of screw rod are connected with bolt 7. The first washer 4 is a steel washer, and the outer diameter of the first washer 4 is larger than that of the nut 1. The second gasket 6 is an elastic gasket. The length of the first sleeve 3 is larger than that of the screw rod 2.
By adopting the double-sleeve structure, the first gasket 4 reduces abrasion, the second gasket 6 reduces impact, the supporting surface is enlarged, the impact force is reduced, the fracture is not easy to occur, the safety of the product is improved, the consumption is reduced, and the cost is reduced; by embedding the SS41 plate 9 on the gray iron body 8, the bolt 7 connects the SS41 plate 9 and the gray iron body 8.
