Abstract
The invention relates to a flanging die for an oil gauge pipe. The flanging die comprises a male die and a female die, wherein, the clearance fit between the pore diameter of the female die and the outer diameter of a workpiece is 0.01mm. The flanging die has the beneficial effects that by adopting the structure, during the flanging process, the diameter size stability of a pipe fitting can be ensured without generating conicity; and in addition, the pipe fitting does not need to be grinded after flanging, thus lowering the machining cost.
Description
Technical field
The present invention relates to a kind of flanging die of pipe fitting, especially relate to a kind of flanging die of engine oil scaleplate pipe.
Background technology
At present,,, adopt special flanging die to make basically, comprise die and punch part particularly for the process application of the very high part of dimensional requirement behind the flange for the overturning process of pipe fitting.For example the flanged edge making of engine oil scaleplate pipe often adopts flanging die processing.For the very high part of the dimensional requirement such as engine oil scaleplate pipe; In order to prevent the variation of diameter dimension behind the pipe fitting flange; And the tapering problem that workpiece can produce behind the flange; Use existing flanging die structure; Normally adopt first flange, and then solve with the peripheral milling processing that shape is arranged.Owing to also will adopt the abrasive grinding wheel of installing on the peripheral milling equipment to carry out grinding again behind the flange, increased manufacturing procedure, must change after the wearing and tearing of cylindrical emery wheel in addition, must cause the rising of processing cost.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, flanging die that can reduce the engine oil scaleplate pipe of processing cost.
The problem that will solve required for the present invention is to realize through following technical scheme: it comprises punch and die, it is characterized in that: the matched in clearance between the aperture of said die and the external diameter of workpiece is 0.01mm.
The said structure that the present invention adopts because the matched in clearance between the external diameter of the aperture of die and workpiece is 0.01mm, can guarantee the stability of pipe fitting diameter dimension during flange like this, also can not produce tapering; In addition, need not grinding behind the pipe fitting flange, reduced processing cost.
Description of drawings
Below in conjunction with accompanying drawing the present invention is done further explanation:
Accompanying drawing is depicted as structural representation of the present invention.
The specific embodiment
Shown in accompanying drawing, the flanging die of this engine oil scaleplate pipe comprises punch 1 and die 2, and the matched in clearance between the external diameter of the aperture of said die 2 and workpiece 3 is 0.01mm.The course of work of the present invention is earlier with the first peripheral milling of the pipe fitting of required flange; Be worked into the size of drawing requirement; Then this workpiece 3 is placed into above the punch 1; Die 2 is to pressed; Then with workpiece 3 flange; Be 0.01mm because the interior circular diameter of die 2 cooperates with the crest clearance of workpiece 3, therefore the diameter dimension of workpiece 3 can not change basically when flange, also can not produce tapering.The present invention is with the described scope of soverlay technique scheme; And the various modification of claim scope change with equivalence; Under the prerequisite that does not depart from technical solution of the present invention, any modification or improvement that those skilled in the art that the present invention did are realized easily all belong to the present invention's scope required for protection.
