Technical field
The utility model relates to sheet-metal press working technical fields, particularly relate to a kind of mould of stamping flange of rolled plate
Tool.
Background technique
Flange is a kind of widely used attachment device, and under normal circumstances, flange processing is mainly using casting, forging, so
It is machined after forming afterwards.Existing main problem is: casting stock utilization is low, and cast-internal is easy to produce shrinkage cavity, loose
Equal forming defects；The disadvantages of forging method is high-quality, but that there are production processes is more, energy consumption is high, production efficiency is low, machining allowance is big；
In addition, there are also turning method etc., there is also problems.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of molds of the stamping flange of rolled plate, with rolling
Round plate is blank, high in machining efficiency, and stock utilization is high.
The mold of the stamping flange includes convex mold, negative mold and extrusion die, and blank is placed in convex mold and cavity plate
Between tool, extrusion die is placed in the negative mold other side.
The formed punch outer diameter of convex mold is consistent with target flange internal diameter, and the small disc diameter of convex mold is not more than blank
Internal diameter.
Using the method for the mould punching forming flange of the stamping flange of the rolled plate, comprise the following steps that
(1) base: taking outer diameter, thickness milling round steel plate identical with outer diameter, the thickness of the big step circles of target flange,
Heating, which is placed on perforating press, carries out punching processing, and the stock volume after punching is 4%-8% bigger than the volume of target flange；
(2) it heats: being heated in the merging heating furnace of blank obtained in step (1), blank heating being arrived
1000℃±50℃；
(3) punching press: the blank after heating in step (2) is moved on in negative mold, and convex mold is along center line to blank side
To punching press, the stop motion when the big step circles lower surface of convex mold reaches flange thickness position；
(4) squeeze: convex mold remains stationary, and extrusion die is reversely squeezed along center line to blank, until the method between mold
Orchid is circled or whirl in the air until chamber is full of by metal, stop motion；
(5) machine: flange finished product is made in deflashing, surface processing.
The above-mentioned technical proposal of the utility model has the beneficial effect that:
The utility model changes the case where previous flange processing, proposes the processing method with round plate punching press flange,
Productivity is effectively improved, stock utilization is improved, machining allowance is small, reduces production cost.Flange " the metal of forming
Fiber " flow direction is complete, improves the mechanical property of flange.

Specific embodiment
In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, below in conjunction with attached drawing
And specific embodiment is described in detail.
The utility model provides a kind of mold of stamping flange of rolled plate.
As shown in Figure 1, the mold includes convex mold 1, negative mold 3 and extrusion die 4, blank 2 is placed in convex mold 1 and cavity plate
Between tool 3, extrusion die 4 is placed in 3 other side of negative mold.
The formed punch outer diameter of convex mold 1 is consistent with target flange internal diameter, the small disc diameter of convex mold 1 and blank 2
Internal diameter is equal or slightly smaller.
It is as follows using the process steps of the mold:
(1) base: taking outer diameter, thickness milling round steel plate identical with outer diameter, the thickness of the big step circles of target flange,
Heating, which is placed on perforating press, carries out punching processing, and the stock volume after punching is 4%-8% bigger than the volume of target flange；Big rule
This plectane is come out by special mill milling when mould produces.
(2) it heats: being heated in the merging heating furnace of blank obtained in step (1), blank heating being arrived
1000℃±50℃；After this process is arranged in roll line when large-scale production, produced using rolling waste heat, punching and circle of contact side exist
A machine tool last time completes.
(3) punching press: by step (2) heat after blank move on on negative mold (3), convex mold (1) along center line to
The punching press of blank direction, the stop motion when the big step circles lower surface of convex mold (1) reaches flange thickness position；
(4) squeeze: convex mold (1) remains stationary, and extrusion die (4) is reversely squeezed along center line to blank, until mold
Between ring flange cavity be full of by metal until, stop motion；
(5) machine: flange finished product is made in deflashing, surface processing.
It is explained combined with specific embodiments below.
In actual production, firstly, base: taking outer diameter, thickness are identical with outer diameter, the thickness of the big step circles of flange to roll
Rounding steel plate, this milling round steel plate is come out by special mill milling when large-scale production, referring to patent " for rolling circle
The spinning shape assembly roller of shape plate ".Centre bore is rushed into the heating of milling round steel plate, according to volume relationship, the volume of blank after punching
It is greater than flange volume, takes stock volume after punching 4%-8% bigger than the volume of target flange, machined after such punch forming
Surplus is small, saves raw material, thereby determines that the diameter of bore of blank.After this process is arranged in roll line when large-scale production, utilize
Waste heat production is rolled, punching and circle of contact side are once completed on a machine tool, and made blank structure schematic diagram is as schemed after punching
4；
Secondly, heating: after processing blank merging heating furnace in heated, by blank heating to 1000 DEG C ±
50℃；
Then, punching press: the blank after heating is moved on in negative mold 3, as shown in Figure 1, stamping die is fixed on press machine
On, the formed punch outer diameter of convex mold 1 is consistent with the internal diameter of flange, and small disc diameter and blank internal diameter are equal or slightly smaller.
Convex mold along center line to 2 direction punching press of blank, the stopping when the big step circles lower surface of convex mold moves on to flange thickness position
Movement, as shown in Figure 2；
Then, squeeze: convex mold remains stationary, and extrusion die 4 is reversely squeezed along center line to blank 2, until between mold
Ring flange cavity be full of by metal until, stop motion, as shown in Figure 3；
Finally, machining: the flange arrangement with overlap obtained after extruding is as shown in Figure 5, it is seen that with above-mentioned stamping die
The flange size shape that the processing method for stamping of tool and the utility model obtains is good, and overlap is few, adds by deflashing, surface
Flange finished product can be made in work.
A kind of stamping flange processing method of the utility model, simple process；For the stamping die of processing, size
Simple easily design, is suitable for large-scale production, therefore can effectively improve production efficiency；The lumber recovery of the utility model compares
Height can effectively reduce the loss of raw material, reduce energy consumption, thereby reduce production cost, " metal is fine for the flange of forming
Dimension " flow direction is complete, improves the mechanical property of flange.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, under the premise of not departing from principle described in the utility model, several improvements and modifications can also be made, these improvement
It also should be regarded as the protection scope of the utility model with retouching.
