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
Technical field
The present invention relates to a kind of moulding process, relate in particular to a kind of plate boss forming technology.
Background technology
Cold extrusion is suitable for parts such as automobile, door lock are processed, but its characteristics are that operation is few, lack rapid shaping man-hour.Existing punching press boss is through on plate, expecting upwards to push out with a countersunk head; When punching press; The tension of plate is excessive, and such technology is suitable for the product that rapidoprint ductility is good, boss is shorter, required precision is not high, and the boss height of going out when needs is during greater than the thickness of plate and for high boss; Can crackle in the boss forming process, occur because of material is not enough, break midway, the cross section is uneven phenomenon, causes the boss height can't reach customer requirement.
Summary of the invention
In order to solve the above-mentioned deficiency that prior art exists, technical problem to be solved by this invention provides a kind of plate boss forming technology.
For achieving the above object, the technical scheme that the present invention adopts is: a kind of plate boss forming technology may further comprise the steps:
A, increase by a blank at the plate side;
B, with the positive and negative rounding of blank, mold near cylindrical;
C, with 90 ° of the bendings that make progress of the cylinder after the chamfering;
Cylinder after d, the bending carries out the cold extrusion shaping;
The unnecessary blank after the cold extrusion is removed in e, shearing, obtains final boss.
Preferably, the cross section of blank described in the step a is square.
Preferably, the volume of blank described in the step a is greater than the volume of boss.
Preferably, the volume of said blank be the boss volume 1.1-1.3 doubly.
The invention solves the defective that exists in the background technology, the present invention makes semi-finished product with blank at the plate side, and bending is got up again; Sealing is forged then, and unnecessary waste material is removed in last deburring, and is easy to operate, production efficiency is high; Make product reach good surface quality, satisfy customer requirement.
Description of drawings
Fig. 1 is the structural representation of boss forming mould of the present invention.
The specific embodiment
Combine accompanying drawing and embodiment that the present invention is done further detailed explanation now, these accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, the boss forming mould is disposed with from top to bottom: upper bolster 1, upper padding plate 2, upper padding plate 3, drift fixed head 4, stripper plate backing plate 5, stripper plate 6, concave template 7, die backing plate 8, die shoe 9.
In the rounding operation, in stripper plate 6, be provided with the stripper plate moulding and insert 10, in concave template 7, be provided with the concave template moulding and insert 11, insert in the concave template moulding and place the parts of required processing on 11.Through the stripper plate moulding insert 10, insert 11 mutual punching press of concave template moulding falls into fillet.
In 90 ° of operations of bending; Upper bolster 1 is provided with and takes off material spring 12, and the below is provided with takes off material push rod 13, takes off material push rod 13 and passes upper padding plate 3, drift fixed head 4, stripper plate backing plate 5, stripper plate 6 successively; Be provided with stripper plate folded block 14 in the stripper plate 6; Be provided with counterdie folded block 15, bending binder block 16 in the concave template 7, be provided with in the die shoe 9 and take off material binder spring 18, binder push rod 17 passes die shoe 9, die backing plate 8 successively.During work, extruding upper bolster 1, upper bolster 1 drives stripper plate folded blocks 14 downward bending parts through stripper plate backing plate 5, and upper bolster 1 is also at its inner material spring 12 that takes off of extruding simultaneously, takes off material spring 12 like this and will drive to take off and expect that push rod 13 pushes downwards.After bending finishes, take off material spring 12, take off and expect that binder spring 18 automatically resets, take off and expect that push rod 13, binder push rod 17 also are returned to initial position thereupon.
In the cylinder trimming; Taking off material spring 19 belows is fixed with through flange 20 and takes off material push rod 21; Taking off material push rod 21 gets in the stripper plate 6 through upper padding plate 2, upper padding plate 3, drift fixed head 4, stripper plate backing plate 5 successively; Bottom at upper padding plate 3 is fixed with shaping drift 22 through drift fixed head 4, is provided with counterdie block 23 in the concave template 7.Extruding upper bolster 1, upper bolster 1 drives shaping drifts 22 downward extruder members through drift fixed head 4, and upper bolster 1 is also at its inner material spring 19 that takes off of extruding simultaneously, takes off material spring 19 like this and will drive to take off and expect that push rod 21 pushes downwards.After extruding finishes, take off material spring 19 and automatically reset, take off material push rod 21 and also be returned to initial position thereupon.
Introduce the lower convex platform moulding process below in detail, may further comprise the steps:
A, to increase a cross section at the plate side be square blank, and the volume of blank is 1.2 times of boss volume;
B, with the positive and negative rounding of blank, mold near cylindrical;
C, with 90 ° of the bendings that make progress of the cylinder after the chamfering;
Cylinder after d, the bending carries out the cold extrusion shaping;
The unnecessary blank after the cold extrusion is removed in e, shearing, obtains final boss.
Above foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm technical scope according to the claim scope.
