Abstract
The utility model discloses a split type upper die at a work station B of a numerical control punch, relates to improvements of a convex die of the punch, and provides the split type upper die at the work station B of the numerical control punch, which can fasten the convex die and improve the work efficiency. The split type upper die comprises a punch pin, a connecting rod, a punch pin sleeve and a set screw, wherein a stepped hole is formed at one end of the punch pin sleeve and an internal thread is formed at the other end of the punch pin sleeve; a stepped circle adaptive to the internal diameter of the punch pin sleeve is arranged at the upper end of the punch pin; the punch pin is connected with the inner part of the punch pin sleeve through the stepped hole; the set screw is connected with the internal thread; and the connecting rod is arranged in the punch pin sleeve and positioned between the punch pin and the set screw. By adopting the upper die, the punch pin is fixed in the punch pin sleeve, the connecting rod is arranged in the middle of the upper die, and one end of the connecting rod is locked by the set screw, so that the punch pin is firmly fixed in the punch pin sleeve; and the punch pin is conically connected with the punch pin sleeve, so that the coaxiality accuracy of the punch pin and the punch pin sleeve is improved and the cooperation between the punch pin and the punch pin sleeve is guaranteed.
Description
Technical field
The utility model relates to mode structure on the punch press, relates in particular to the improvement of punch press punch (drift) structure.
Background technology
Punch is the part that is used for the moulded products inner surface in the mould.In the diel, the punch main part that is absolutely necessary belongs to removable mould consumptive material.Punch according to the difference of material, shape, purposes can be divided into guiding punch, primary and secondary punch, take out the tooth punch, detect the tip, hexagonal punch, oval punch, forming convax mould, fan type punch, special-shaped punch, high-speed steel punch, wolfram steel punch etc.
Diel utilizes the mould that is installed on the forcing press that material is exerted pressure in cold stamping processing, and material (metal or nonmetal) is processed into part (or semi-finished product).In this process, punch directly contacts with material, can receive the material drag effects, and continuous operation simultaneously causes punch to come off easily, makes troubles to work.
The utility model content
The utility model provides a kind of fastening punch, the split type patrix of numerical control press B station of increasing work efficiency to above problem.
The technical scheme of the utility model is: comprises drift and connecting rod, also comprises drift cover and holding screw,
Said drift overlaps an end and is provided with shoulder hole, and the other end is provided with internal thread;
The upper end of said drift is provided with and the adaptive step circle of said drift cover internal diameter, and said drift is connected in the said drift cover through said shoulder hole;
Said holding screw is connected with said internal thread;
Said connecting rod is located in the said drift cover, between said drift and said holding screw.
Said drift and said shoulder hole taper connection.
The utility model is fixed on drift in the drift cover, and in the middle of connecting rod was located at, an end was locked with holding screw, makes drift be fixed on firmly in the drift cover; Drift and drift cover taper connection have improved coaxial accuracy, have guaranteed to cooperate between the two.The utility model changes existing structure into split type, and the position relation of fastening drift has improved operating efficiency.
