Abstract
The utility model discloses an oil tube upset head die which comprises a forming die seat and a forming die core which is arranged on the forming die seat. The oil tube upset head die further comprises a pre-punch die seat and a pre-punch die core which is arranged on the pre-punch die seat. Final forming in twice through the pre-punch die core and the forming die core is achieved. The size uniformity of an oil tube upset head is good, size accuracy is high, rejection rate is low, sealing performance of an oil tube is guaranteed, and cost is saved.
Description
Technical field
The utility model relates to oil pipe heading technical field, especially relates to a kind of oil pipe upset head mould.
Background technology
Along with the development of automotive engineering, the automobile oil pipe product type constantly increases, and is more and more higher to the quality requirement of oil pipe.The end Forming Quality of oil pipe is extremely important to oil pipe, particularly on the impact of oil pipe sealing effectiveness.Wherein, the quality of oil pipe upset head mould plays conclusive effect to the oil pipe end Forming Quality.Existing oil pipe upset head mould is of low quality to the oil pipe heading, and production efficiency is low, poor dimensional precision, the very difficult sealing that guarantees oil pipe.
The utility model content
Technical problem to be solved in the utility model provides a kind of oil pipe upset head mould, its objective is that oil pipe heading precision is high, guarantees that oil pipe has good sealing property.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of oil pipe upset head mould, comprise shaping mould base and formation die core, and described formation die core is located on the shaping mould base, also comprise pre-die shoe and pre-die center, described pre-die center is located on the pre-die shoe.
Be provided with the installing hole of step in the described pre-die shoe, pre-die center one end and installing hole are suitable.
Be equipped with locating slot on described shaping mould base and the pre-die shoe.
The utility model compared with prior art has the following advantages: by pre-die center and formation die core final molding at twice, oil pipe heading dimensional uniformity is good, and dimensional accuracy is high, and percent defective is low, guarantees that oil pipe has good sealing property, saves cost.
