Technical field
The invention belongs to Machining Technology field, relate to a kind of forcing press that utilizes and carry out the method that the frustum of a cone is curved, proofread and correct.
Background technology
In complete engineering goods, often there is the frustum of a cone of a lot of nonstandard sizes need be with curved, the welding production of steel plate, but owing to being subject to the restriction of size, shape, cannot complete with veneer reeling machine, of forcing press (hereinafter to be referred as forcing press), making must design specialized mould, divide half compacting, then weld, postwelding is because welding deformation is repaiied school difficulty, of poor quality, labour intensity is high, waste time and energy less economical (weld seam has two, the secondary cut pressure head waste steel of also must ruling).Therefore,, for curved, the correction of the frustum of a cone, just become one of mechanical processing industry and be badly in need of the technical barrier solving.
Summary of the invention
The object of this invention is to provide a kind of forcing press that utilizes and carry out the method that the frustum of a cone is curved, proofread and correct, having solved under prior art condition must design specialized mould, minute half compacting, then weld, postwelding is because welding deformation is repaiied school difficulty, of poor quality, labour intensity is high, the problem wasting time and energy.
The technical solution adopted in the present invention is that a kind of forcing press that utilizes carries out the method that the frustum of a cone is curved, proofread and correct, and according to following steps, specifically implements:
Step 1, according to the figure paper size blanking of the frustum of a cone to be processed, blanking is shaped as fan out material, marks the bus of the frustum of a cone;
Step 2, makes upper die and lower die according to frustum of a cone figure paper size, and patrix is fixed on forcing press upper table lower surface, counterdie is fixed on forcing press lower table upper surface simultaneously;
Step 3, fan out material is lain on counterdie, make the bus that pulls on fan out material and the longitudinal centre line centering of counterdie, starting pressure machine, patrix is moved down with forcing press upper table, the a pair of fan out material being placed on counterdie of round steel is exerted pressure and is made flitch generation plastic deformation, and round steel one often presses down once and afterwards the flitch on counterdie moved once by bus;
Step 4, successively repeatedly compacting, mobile fan out material, until frustum of a cone flitch heals up, joint close spot welding is fixed;
Step 5, removes movable steel plate, from the round steel one of patrix, draws off the frustum of a cone, and the frustum of a cone is healed up and locates to weld firm and reconditioning weld seam, obtains the not too frustum of a cone of rule of shape;
Step 6, the frustum of a cone after reconditioning is packed into round steel one again from the movable steel plate of patrix, connect movable steel plate, curved method according to step 3 bus longitudinal centering is suppressed repeatedly to the frustum of a cone, limit rectification limit checking measurements, until obtain meeting the regular frustum of a cone of drawing requirement, finally take away movable steel plate, from the round steel one of patrix, take out the qualified frustum of a cone that is shaped.
The invention has the beneficial effects as follows, utilize the pressure that forcing press provides, by simple mould, staphylion is repeatedly suppressed, closed to steel plate admittedly, after welding, carry out near butt welding mouth more compressing, the method is as long as angle or the length of replaceable mould counterdie round steel just can be made the frustum of a cone of different size, thickness, realize many specifications of mold frustum and use, reduce welding capacity, reached the object that reduces welding deformation, and do not need secondary cut pressure head, reached the object of saving material.
