Abstract
The invention provides a kind of localization method for stamping automobile outer panel covering part, comprise the following steps that:1) product zone and garbage area and a trimming line and secondary trimming line are set on product plate, trimming line is to repair the line of demarcation for rushing product zone and garbage area in operation, one time one section of the centre of trimming line is the reserved punch area of triangle punching, the reserved punch area is two, along a trimming line and column distribution;2) repairing rushes the deburring and triangle punching that operation completes product simultaneously, and triangle punching is equilateral triangle;3) using triangle punching as product location hole, using positioning finger setting product;4) secondary deburring and the flange of product are completed simultaneously in overturning process, the secondary deburring of product and flange are respectively on the basis of secondary trimming line and flange line.This invention ensures that the precision of product positioning so that the fixation of product is more firm, it is to avoid product turn over whole sequence because product vibration and caused by the problem that cannot ensure part accuracy.
Description
Technical field
The present invention relates to mould punching process in mold design technical field, more particularly to a kind of automobile panel.
Background technology
With the fast development of auto industry, it is comprehensive that Moral quality card, service, quality, cost etc. have entered in each main engine plants
How competition, as the key target for investment during Operational preparation, improve the surface quality of the quality of part, particularly outer covering piece
Have become the theme that each main engine plants and mould factory are competitively studied.
After large-scale stamping parts drawing and moulding, the positioning on follow-up trimming die typically can reach very well using type face positioning
Locating effect, but some drawing depths are shallower and repaiied in the first sequence using the drawn component that type face positioning precision does not reach requirement
Bian Shiruo also then occurs many problems using type face positioning, and locating effect is not good, is generally positioned using addition pin stop, but
It is that stabilization still can not be reached to the locating effect of some special part pin stop.
In sum, in the prior art in the presence of following technical problem:Drawing depth it is shallower and using type face positioning precision without
Method reaches the orientation problem of the drawn component in postorder of requirement.
The content of the invention
The purpose of the present invention is directed to and above-mentioned there is problem, there is provided the mould punching technique side in a kind of automobile panel
Method, solves the postorder orientation problem of shallow recessing part.
It is that, up to above-mentioned purpose, the present invention is achieved through the following technical solutions:
A kind of mould punching process in automobile panel, the garbage area for rushing operation for repairing rushes location hole, uses in advance
The pre- location hole that rushes positions product as the location hole of finishing operations, comprises the following steps that:
S1, setting product zone and the garbage area on product plate, set a trimming line and secondary trimming line and its spacing, once
Trimming line is to repair the line of demarcation for rushing product zone and garbage area in operation, and a both sides for trimming line are straight line, and middle one section is convex
Molded line, convex line part is reserved punch area, and the reserved punch area is two, and along a trimming line and column distribution, two pre-
The spacing of punch area is stayed more than the 50% of product section length;Triangle punching is located at reserved punch area, a side of triangle punching
Boundary line parallel with secondary trimming line and as product, between two other side of triangle punching is vertical with trimming line
Away from not less than 20mm;
S2, repairing rush operation simultaneously complete product a deburring and triangle punching, a deburring with a trimming line be base
Standard, triangle punching is equilateral triangle;
S3, using triangle punching as product location hole, using finger setting product is positioned, alignment pin is cylindrical type, alignment pin
Connect in the cylindrical equilateral triangle with triangle punching;
S4, the secondary deburring and the flange that complete product simultaneously in overturning process, the secondary deburring of product and flange are respectively with secondary
On the basis of trimming line and flange line.
Further, the spacing of a trimming line and secondary trimming line straightway is 1mm.
Further, the triangle punching is the external equilateral triangle of diameter 21mm circles, the corner of equilateral triangle
The fillet of R3;A diameter of 21mm of alignment pin.
The beneficial effects of the invention are as follows:For the exterior panel that cannot add Sheet Metal Forming Technology location hole, the method is turning over whole work
Sequence realizes hole positioning, it is ensured that the precision of product positioning so that the fixation of product is more firm, it is to avoid product is turning over whole sequence
Because of product vibration and caused by the problem that cannot ensure part accuracy.
Brief description of the drawings
Fig. 1 is product last time trimming line, secondary trimming line and triangle punching position schematic diagram.
Fig. 2 is overturning process view.
In figure:1- product zones, 2- garbage areas, trimming line of 3-, bis- trimming lines of 4-, 5- reserves punch area, 6- triangles
Shape punching, 7- alignment pins, 8- flange lines.
Specific embodiment
The present invention is described in further detail below by specific embodiment combination accompanying drawing.
By taking the deburring of cover outside plate, flange as an example, comprise the following steps that:
1) product zone 1 and garbage area 2 are set on product plate, a trimming line 3 and secondary trimming line 4 and its spacing is set,
The spacing of trimming line and secondary trimming line straightway is 0.5mm, hands over knife, a trimming line 3 to rush operation to repair as technique
Middle product zone 1 and the line of demarcation of garbage area 2, a both sides for trimming line 3 are straight line, and middle one section is convex line, convex line portion
It is divided into reserved punch area 5, the reserved punch area is two, along a trimming line and column distribution, between two reserved punch areas
Away from 50% more than product section length;Triangle punching 6 is located at reserved punch area 5, and a side of triangle punching 6 is repaiied with secondary
Sideline 4 is parallel and boundary line as product, and two other side and the vertical interval of a trimming line 3 of triangle punching 6 are
15mm;The effect of two reserved punch areas is so that the fixation of product is more firm.
2) repairing rushes the deburring and triangle punching 6 that operation completes product simultaneously, and a deburring is with a trimming line 3
On the basis of, the external equilateral triangle that triangle punching 6 is justified for diameter 16mm, fall the fillet of R3 for the corner of equilateral triangle;
3) using triangle punching 6 as product location hole, product is positioned using alignment pin 7, solves to be positioned when cover outside plate is placed
Inaccurate problem, alignment pin 7 be cylindrical type, a diameter of 16mm of alignment pin, the cylindrical and triangle punching 6 of alignment pin 7
Connect in equilateral triangle;
4) secondary deburring and the flange of product are completed simultaneously in overturning process, wherein secondary deburring insert and flange insert are same
Insert, secondary deburring and flange work are completed simultaneously, and the secondary deburring of product and flange are respectively with secondary trimming line 4 and flange line
On the basis of 8.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to assert
Specific implementation of the invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of not departing from present inventive concept, some simple deduction or replace can also be made, should be all considered as belonging to of the invention
Protection domain.
