Abstract
The invention discloses a flanged hole processing method for a hole flanging structure of special specifications. The method comprises the following steps of: I, raising: stretching a metal material needed by hole flanging towards a hole flanging side, wherein a raised bottom surface is an inwardly-concave spherical surface; II, punching a prefabricated hole and removing residual size of the metal material; III, shaping a flanged hole, wherein the height of the shaped flanged hole is larger than a required height; IV, upsetting height and chambering an oblique angle: chambering an oblique angle on the lower edge of the flanged hole while adjusting the height of the flanged hole, and upsetting the upper edge of the flanged hole flatly; and V, chamfering an oblique angle: chamfering an oblique angle on the upper edge of the flanged hole. After the method is applied to practical production, size required by the hole flanging structure of special specifications can be well ensured, and production efficiency is increased greatly; and the method has a good popularization value.
Description
Technical field
The present invention relates to a kind of machining process, specifically a kind of hole flanging processing method of special requirement hole flanging structure.
Background technology
Hole flanging processing refers to translates into the edge drawing of pre-manufactured hole on sheet metal by hole flanging mold the forming and machining method of erectting straight flange, is widely used in the process of sheet metal.In the face of the hole flanging structure of conventional specification, general hole flanging processing method is: one, punching press pre-manufactured hole; Two, hole flanging is shaped.
Referring to Fig. 1, the hole flanging structure of existing a kind of special requirement, its special character is: one, the material of sheet metal is structural alloy steel, has higher tensile strength; Two, sheet metal thickness t reaches 3 millimeters; Three, hole flanging height h is high, and requirement is 7.2 millimeters, and hole flanging aperture d is 10.5 millimeters; Four, be shaped after the upper lower rim of endoporus all to need be the oblique angle c of 0.5 millimeter; Five, endoporus tapping after moulding, and tooth hole pulling force needs to bear 40 kgfs.
In the face of the hole flanging structure of above-mentioned special requirement, the hole flanging that adopts general conventional hole flanging processing method to be shaped, hole flanging height cannot be up to standard, there is hole flanging cracking phenomena, cannot carry out endoporus tapping, more cannot bear 40 kgfs, and after being shaped on endoporus the fillet of lower rim excessive, cannot reprocess is shaped is at all the bevelling of 0.5 millimeter.
In the face of the hole flanging structure of above-mentioned special requirement, general conventional hole flanging processing method cannot shape the hole flanging structure meeting the demands.As improvement, can adopt the be shaped hole flanging structure of above-mentioned special requirement of a kind of welding processing, after specifically the torus of requirement up to specification being shaped separately, be welded on sheet metal.But this process steps is many, cost is high, efficiency is low, and the position degree of hole flanging structure on sheet metal is difficult to accurate guarantee.
Summary of the invention
The object of this invention is to provide a kind of hole flanging processing method of special requirement hole flanging structure, cannot shape the problem of special requirement hole flanging structure to solve general conventional hole flanging processing method, and there is high efficiency, feature cheaply.
For achieving the above object, the technical solution used in the present invention is: a kind of hole flanging processing method of special requirement hole flanging structure, comprises the following steps:
One, raising, metal material required hole flanging is stretched to hole flanging one side, and the bottom surface of raising is the sphere of indent;
Two, punching press pre-manufactured hole, removes the metal material of unnecessary volume;
Three, hole flanging is shaped, and the hole flanging height after shaping exceeds requirement height;
Four, upsetting height the oblique angle that falls down is by hole flanging lower rim bevelling, and flat by the upsetting of hole flanging upper rim when adjusting hole flanging height;
Five, fall top rade, by hole flanging upper rim bevelling.
Adopt technical scheme of the present invention, first implement raising step, therefore can gather enough metal materials in follow-up hole flanging position, can ensure height and the wall thickness of hole flanging, and cracking phenomena does not occur, and then effectively ensure the holding capacity after endoporus tapping; In upsetting height time, can utilize enough metal materials that fillet upsetting excessive hole flanging upper rim is flat, makes follow-uply can pour out desired oblique angle; Technical scheme of the present invention can be processed continuously by hole flanging mold, and automation is shaped, and compares the processing method of welding forming, has high efficiency, feature cheaply.The present invention is for after actual production, and the desired size of special requirement hole flanging structure can be able to fine guarantee, and significantly enhances productivity, and has good promotional value.
