Description
Technical field
The present invention relates to Stamping Die Technology field, more particularly to a kind of automatic stamping equipment of thin-walled annular workpiece.
Background technology
There is kind of a thin-walled annular product in production, its shape connects for the big ring of a sectional area and the small ring of a sectional area
Together, and there is a centre bore in centre, wherein, its wall thickness of the small ring of sectional area only has 0.8 millimeter, belongs to thin-wall product,
Difficulty is larger during this Product processing, currently in order to being applicable in batch production, is mostly processed using stamping die.
In stamping die, stepping punching mould is received much concern with producing continuous, production efficiency height, stepping punching mould
Refer to forcing press in one stroke, complete the stamping die of multi-step forming processes at the same time sequentially on the several different positions of mould
Tool.Traditional mould structure is eight pieces of harden structures or nine pieces of harden structures, and eight blocks of plates are upper and lower die holder, punch retainer, punch-pin
Backing plate, die block, cavity plate backing plate, stripper, discharging backing plate；Nine pieces of harden structures are to add a stock guide.One
The techniques such as the punching of part, flange, bending, drawing, solid forming can be completed in secondary stepping punching mould.
But the different annular workpieces of two kinds of sectional areas but have very big difficulty using stepping punching mould, first, thin-walled work
Part is made of thin-walled steel strip stamping, and Steel Thin-Wall band positions hardly possible in moving process, after especially stamping out several holes, itself
Deformation is big, and the intensity of steel band is small, and displacement location is difficult, therefore causes multiple station positions inaccurate, and finished product rate is low；Two
It is that the different annular workpieces of sectional area are difficult to demould on stepping punching mould, complex production process；Third, after punch forming, need
Its size is detected, particularly axially height, can produce the underproof phenomenon of axial height in punching course, radially
Thickness deflection in punching course is little, it is not necessary to detects, in the manufacturing process of the different annular work piece of sectional area, and punching press
During need mould, corresponding mould is also required in detection process, after the completion of punching press, by product by being taken out in stamping die,
It is installed in detection mould and is detected again, it is not only time-consuming and laborious, but also inefficiency, it can only be inspected by random samples, it is impossible to accomplish every
Part finished product is all checked that therefore, product quality can not be protected completely.
Therefore, based on drawbacks described above, in stamping equipment field, for New Thin-walled annular work piece automatic stamping equipment still
In the presence of research and improved demand, this is also a research hotspot and emphasis in current stamping equipment field, is even more the present invention

Spring 1503, compression spring 1503 are set in sensing section 1504；Pressed sheet 3 holds out against ring 302 equipped with detection, and detection holds out against ring
302 position is corresponding with the position on detection bullet top 15, and when pressed sheet 3 is depressed, detection holds out against ring 302 and holds out against on forming panel 10
Annular workpieces, the one end for detecting bullet top 15 and stretching out lower template 9 is pushed, as fruit product is qualified, then detects the bottom on bullet top 15
Just contact induction piece 16, at this time sensing chip 16 provide an inductive signal, represent sintetics, as fruit product is unqualified, then
The bottom on detection bullet top 15 is unable to contact induction piece 16, and sensing chip 16 provides another inductive signal at this time, represents waste product.
Die holder 8 is equipped with go-no-go bullet top 17, and go-no-go bullet top 17 is vertical positioned at the downstream on detection bullet top 15, go-no-go bullet top 17
It is slidably mounted on die holder 8, lower template 9 is stretched out at the top on go-no-go bullet top 17, and corresponding, forming panel 10 is equipped with go-no-go
Cavity plate 1005.In order to cause the annular workpieces after ejection punching press that go-no-go bullet top 17 tries one's best more, in the lower surface of pressed sheet 3
Equipped with go-no-go depression 303, the position of go-no-go depression 303 is corresponding with go-no-go bullet top 17, also, the sectional area of go-no-go depression 303
More than or equal to the big end cross-sectional area of circular thin-wall workpiece, and shape is corresponding, and ring is accommodated when being jacked up in order to go-no-go bullet top 17
Shape workpiece.
Go-no-go bullet top 17 has a centre bore axially through go-no-go bullet top 17, and die holder 8 is equipped with a gas channel
19, gas channel 19 connects centre bore, and gas channel 19 connects a solenoid directional control valve 18, and gas channel 19 is connected with high-pressure air source
Connect, solenoid directional control valve 18 plays the role of connection or closes high-pressure air source.
Sensing chip 16 and solenoid directional control valve 18 are all connected with control unit, sensing chip 16 and 18 generally use of solenoid directional control valve electricity
Even mode, which connects, connects control unit, naturally it is also possible to connects control unit, people in the art using wireless signal connection mode
Member can sets itself as needed, be not limited thereto, control unit is usually PLC programmable controller, and sensing chip 16 will
Signal is transmitted to PLC, and PLC provides instruction after program compares, and control solenoid directional control valve 18 acts, if testing result is into
Product, then 18 closed gas flow passage 19 of solenoid directional control valve, go-no-go bullet top 17 only finished work-piece is jacked up, follow-up work personnel concentrate receive
Collection；If testing result is waste product part, solenoid directional control valve 18 connects gas channel 19, and during die sinking, go-no-go bullet top 17 jacks up useless
While product workpiece, the high pressure draught in gas channel 19 blows out waste product workpiece, and waste product workpiece can be realized from shaping mould
Picked out in tool, so that each workpiece of punching press can be detected, and also it is efficient, product quality is stablized.
As Fig. 5 and Fig. 6 are jointly shown, the bottom of forming panel 10 is equipped with a guiding surface 1006, guiding surface 1006
