A kind of earpiece molding assembly that the present embodiment is provided, including upper forming blocks 100 and lower forming blocks 200, both
Mutually it is correspondingly arranged up and down, and the first punching work is provided with upper forming blocks 100 and the relative position of lower forming blocks 200
Position, thick cut position, shaping station, the second punching station and fine cut station, and these stations are sequentially arranged in order；
Wherein, the first punching station of upper forming blocks 100 includes two the first drifts 101 of cylinder, and the two first
Drift 101 is arranged on the edge of the width of forming blocks 100, and the direction and upper forming blocks 100 of both lines width
The line for having the first drift 101 of angle, i.e., two between direction is oblique relative to the width of upper forming blocks 100
State；First station of lower forming blocks 200 includes two manholes 201, and the two manholes 201 and upper forming blocks 100
On two the first drifts 101 be engaged, for the location hole on stamping blanks；When upper forming blocks 100 are vertically close to
During lower forming blocks 200, during blank is punched through and inserts the manhole 201 of correspondence position by two the first drifts 101, to complete base
Expect the punching press of upper Positioning holes.
It is I-shaped heavy-duty tool tool 102, heavy-duty tool tool that the thick cut position of upper forming blocks 100 is specially cross section
102 both sides are respectively arranged with the groove-like structure for using cooperatively, and heavy-duty tool has 102 inclined settings；Lower forming blocks 200
Thick cut position be have holes 202, upper and lower two thick cuts position mutual cooperations with the I-shaped heavy-duty tools that match of heavy-duty tool tool 102
Substantially outline for cutting workpiece；When blank complete rush location hole operation when, be advanced into thick cutting process, on into
Type block 100 is moved down, and is first the general profile that the groove-like structure for having 102 sides by heavy-duty tool cuts out workpiece side, Ran Houji
Continuous to move forward blank, upper forming blocks 100 move down the groove-like structure for having 102 opposite sides by heavy-duty tool again, and to cut out workpiece another
The general profile of side, but by the thick cutting process in both sides after, workpiece cuts off not from blank, and the two ends of workpiece remain attached to
On blank, subsequent fine cutting process is waited to cut off workpiece from blank completely.
The shaping station of upper forming blocks 100 includes multiple molding cutters, and it is raised that these molding cutters are round rectangle
103, the height of each round rectangle projection 103 increases successively, and inclined setting；The shaping work of lower forming blocks 200
Position includes multiple round rectangle grooves 203, and these round rectangle grooves 203 are engaged with round rectangle projection 103, and each is justified
The depth of angular moment connected in star 203 increases successively；By the molding cutter and round rectangle groove 203 of round rectangle projection 103
Use cooperatively, can stamp out on blank cross section for round rectangle projection 103 structures, and by Multi-step forming into
Type, reduces due to the deformation of the blank that punching press is caused.
It should be noted that due to workpiece need shaping cell body depth dimensions it is larger, using it is one time punching molded when hold
Easily make blank that deformation is produced in forming process, and one time punching molded deeper cell body needs larger stamping press, liquidates
Pressure equipment can also have adverse effect in itself, based on this, the process that the cell body is molded is divided into multi-pass punch forming, and often
Secondary press depth gradually increases, so as to finally realize larger punching press amount by multiple less punching press amount, completes depth gauge rule
The punch forming of very little larger cell body.
Second punching station of upper forming blocks 100 is that cross section is the second drift 104 of round rectangle, second drift
104 cross section is identical with the cross section size of the molding cutter of round rectangle, but the height dimension of the second drift 104
It is similarly and is obliquely installed more than the size of any one molding cutter, and the second drift 104；Second punching of lower forming blocks 200
Station is specially round rectangle through hole 204, and the round rectangle through hole 204 is engaged with the second drift 104；When upper forming blocks
100 when moving down, and drives the second drift 104 to move down in the lump and press to the cell body of the round rectangle on blank, due to the second punching
First 104 height dimension carries out punching press more than the size of molding cutter therefore, it is possible to the cell body bottom to round rectangle, by the
Two drifts 104 are used cooperatively with round rectangle through hole 204, can be washed out the bottom of the cell body of round rectangle, in order to rear
It is continuous to use.
Upper forming blocks 100, the fine cut station of lower forming blocks 200 are respectively fine cut cutter 105 and I-shaped fine cut cutter holes
205, and the cross section of fine cut cutter 105 is identical with the cross section of heavy-duty tool tool 102, the cooperation of upper and lower two fine cut stations
Use, for workpiece to be cut off from blank.
It should be noted that the groove-like structure of the both sides of fine cut cutter 105 be according to the specific size design of workpiece out,
And the groove-like structure of both sides can be snapped together, space between the two matches with the profile of workpiece just such that it is able to
By accurately being cut down from blank with the use of by workpiece for fine cut cutter 105 and I-shaped fine cut cutter holes 205.
In the optional technical scheme of the present embodiment, heavy-duty tool tool 102, each molding cutter, the second drift 104 and fine cut
Cutter 105 is inclined to set, and angle of inclination is identical with the angle of inclination of two lines of the first drift 101.
It should be noted that some earpiece are screen cloth structure, and screen cloth is necessary for sideling cutting, in case vertical cut out now
Fall the phenomenon of silk, therefore, earpiece molding assembly is designed according to the concrete structure of earpiece, earpiece molding assembly
On punch forming structure be also obliquely installed accordingly.
In the optional technical scheme of the present embodiment, molding cutter is specially three groups.
It should be noted that because the groove part of the model earpiece is deeper, being caused by one time punching molded meeting
Blank produces larger deformation during punch forming, so as to influence the precision of shaping workpiece, at the same time, is needing compared with favourable opposition
During pressure, former can bear larger power, if things go on like this influence whether the service life of former.Therefore, using many
Passage punch forming operation, to complete this kind of punch forming of earpiece, it is preferable that take three passage punching presses in the present embodiment
Shaping, i.e., molding cutter is set to three groups.
In the optional technical scheme of the present embodiment, the edge on each molding cutter top is fillet；In view of forming cutter
The top of tool can influence the shaping essence of workpiece without blunt during punch forming by blank and the surface tear of workpiece
Degree, and fillet is larger with the contact area of blank, and some positions for the workpiece for being unlikely to make after shaping produce concentrated stress, shadow
Ring the performance of workpiece.
In the optional technical scheme of the present embodiment, multiple pilot pins 106 are provided with upper forming blocks 100, and these are positioned
Pin 106 is arranged on the edge of the width both sides of forming blocks 100, the pilot pin 106 per side and the first of relevant position
Drift 101 is in line, and the line of the pilot pin 106 of both sides is parallel with the line of the first drift 101 of both sides.
The purpose for setting pilot pin 106 in upper forming blocks 100 is to be stamped out on blank by the first punching station
Location hole, needed by pilot pin 106 through location hole before by punch forming next time to realize blank in punch forming
Front position determination, so just can guarantee that accurate punch forming, and then improve stamping forming precision, reduce and strike out
The quantity of type defect ware.
