Abstract

The invention relates to a molding process for a boss of a plate material. The molding process comprises the steps of: a, adding a blank on a lateral side of the plate material; b, chamfering the front side and the back side of the blank so as to form an approximately columnar shape; c, upwards-bending the chamfered column about 90 degrees; d, subjecting cold-extruding reshaping to the bent column; e, cutting off the extra blank after the cold extrusion so as to obtain the final boss. The invention is characterized by processing the blank into a semi-finished product at the lateral side of the plate material and then bending upwards, performing enclosed forging and then trimming to remove the extra waste, the operation is convenient, the production efficiency is high, and the good surface quality of the product is achieved, thereby meeting the requirements of customers.

Description

Molding process for boss of plate material
Technical field
The present invention relates to a kind of moulding process, relate in particular to a kind of molding process for boss of plate material.
Background technology
Cold extrusion is suitable for the part such as automobile, door lock to process, and its feature is that operation is few, man-hour is short, can rapid shaping.Existing punching press boss is by material upwards being pushed out with a countersunk head on plate, in the time of punching press, the tension of plate is excessive, such technique is suitable for the product that rapidoprint ductility is good, boss is shorter, required precision is not high, the boss height of going out when needs is greater than the thickness of plate and during for high boss, can in boss forming process, there is crackle because material is not enough, break midway, cross section is uneven phenomenon, causes boss height cannot reach customer requirement.
Summary of the invention
In order to solve prior art above shortcomings, technical problem to be solved by this invention is to provide a kind of molding process for boss of plate material.
For achieving the above object, the technical solution used in the present invention is: a kind of molding process for boss of plate material, comprises the following steps:
A, increase by a compact material at plate side;
B, by the positive and negative rounding of blank, mold near cylindrical, in rounding operation, in stripper plate, being provided with stripper plate moulding inserts, in concave template, is provided with concave template moulding and insert, on concave template moulding is inserted, place described blank, change into fillet by the mutual punching press that stripper plate moulding is inserted, concave template moulding is inserted;
C, by upwards 90 ° of bendings of the cylinder after chamfering, in 90 ° of operations of bending, on upper bolster, be provided with the first de-material spring, below is provided with the first de-material push rod, the first de-material push rod is successively through the second upper padding plate, punch fixing plate, stripper plate backing plate, stripper plate, in stripper plate, be provided with stripper plate folded block, in concave template, be provided with counterdie folded block, bending binder block, in die shoe, be provided with de-material binder spring, binder push rod is successively through die shoe, die backing plate, extruding upper bolster, upper bolster drives stripper plate folded block downward bending parts by stripper plate backing plate, upper bolster also takes off material spring in first of its inside of extruding simultaneously, the such first de-material spring will drive the first de-material push rod to push downwards, complete bending in 90 °,
D, cylinder after bending carries out cold extrusion shaping, in cylinder trimming, the second de-material spring below is fixed with the second de-material push rod by flange, the second de-material push rod is successively through the first upper padding plate, the second upper padding plate, punch fixing plate, stripper plate backing plate enters in stripper plate, bottom at the second upper padding plate is fixed with shaping drift by punch fixing plate, in concave template, be provided with counterdie block, extruding upper bolster drives the downward extruder member of shaping drift by punch fixing plate, upper bolster also takes off material spring in second of its inside of extruding simultaneously, the such second de-material spring will drive the second de-material push rod to push downwards,
Unnecessary blank after e, shear removal cold extrusion, obtains final boss.
Preferably, the cross section of blank described in step a is square.
Preferably, the volume of blank described in step a is greater than the volume of boss.
Preferably, the volume of described blank be boss volume 1.1-1.3 doubly.
The invention solves the defect existing in background technology, the present invention makes semi-finished product by blank at plate side, then bending is got up, then sealing is forged, and unnecessary waste material is removed in last deburring, easy to operate, production efficiency is high, the surface quality that product has been reached, meets customer requirement.
Accompanying drawing explanation
Fig. 1 is the structural representation of boss forming mould of the present invention;
The specific embodiment
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figure 1, boss forming mould, is disposed with from top to bottom: upper bolster 1, the first upper padding plate 2, the second upper padding plate 3, punch fixing plate 4, stripper plate backing plate 5, stripper plate 6, concave template 7, die backing plate 8, die shoe 9.
In rounding operation, in stripper plate 6, be provided with stripper plate moulding and insert 10, in concave template 7, be provided with concave template moulding and insert 11, insert and place the parts of required processing on 11 in concave template moulding.By stripper plate moulding insert 10, insert 11 mutual punching press of concave template moulding changes into fillet.
In 90 ° of operations of bending, on upper bolster 1, be provided with the first de-material spring 12, below is provided with the first de-material push rod 13, the first de-material push rod 13 is successively through the second upper padding plate 3, punch fixing plate 4, stripper plate backing plate 5, stripper plate 6, in stripper plate 6, be provided with stripper plate folded block 14, in concave template 7, be provided with counterdie folded block 15, bending binder block 16, be provided with de-material binder spring 18 in die shoe 9, binder push rod 17 is successively through die shoe 9, die backing plate 8.When work, extruding upper bolster 1, upper bolster 1 drive stripper plate folded block 14 downward bending parts by stripper plate backing plate 5, upper bolster 1 is also at the first de-material spring 12 of its inside of extruding simultaneously, and the such first de-material spring 12 will drive the first de-material push rod 13 to push downwards.After bending, the first de-material spring 12, de-material binder spring 18 automatically reset, and the first de-material push rod 13, binder push rod 17 are also returned to initial position thereupon.
