Abstract
The utility model provides a roller-mold forge press which only needs smaller forming force and can also obtain forged pieces with better precision. The roller-mold forge press is characterized in that when a slide block (7, 17) of the roller-mold forge press does a reciprocating rectilinear motion along an upper transverse beam or a lower transverse beam of a bed body (1, 11), a fan-shaped roller forging block (3) which is provided with a circular arc-shaped upper mold (4) is driven to do reciprocating rolling press around a mandrel (2) on a workblank (5) by utilizing friction force among the metal workblank (5) and upper and lower molds (4, 6) so as to cause the workblank (5) to deform continuously and to form into the forged piece.
Description
The utility model relates to the equipment that a kind of metal forming is used.
At present, the equipment that metal forming is used is classified from the motion mode of upper die and lower die, mainly contains two classes: 1. patrix is with respect to the counterdie moving linearly; 2. upper die and lower die are made relative rotary motion.The former that belongs to the 1st class has toggle joint press, fly press, hydraulic press and various hammers etc.When being shaped with this kind equipment, metal is the process that is in bulk deformation, and its advantage is: the ratio of precision of shaping forging is better, often is used as last finish-forging and is shaped; Its shortcoming is: needed strength is very big during shaping, so the tonnage of equipment and investment are all very big.The former that belongs to the 2nd class has forging roll, milling train etc.When being shaped with this kind equipment, metal is the process that is in continuous local deformation, and its advantage is: needed strength is little during shaping, so the tonnage of equipment and investment are all smaller; Its shortcoming is: the precision of shaping forging is relatively poor, and often the blocking of only using as base is shaped.In actual production, usually toggle joint press or the supporting use of fly press used of forging roll that base is used and finish-forging.
The purpose of this utility model be to provide a kind of not only only needed less plastic force can obtain not only precision preferably forging, can base but also former---roller die forging press that can finish-forging.
Accompanying drawing 1 is the schematic diagram of roller die forging press of the present utility model.
In accompanying drawing 1,1) be lathe bed, (2) are axles, and (3) are fan-shaped roll forging pieces, and (4) are the circular arc patrixes, and (5) are metal blanks, and (6) are counterdies, and (7) are slide blocks.With axle (2) that slide block (7) is hinged with the roll forging piece (3) that patrix (4) is housed, place under the entablature of lathe bed (1).Counterdie (6) is fixed on the sill of lathe bed (1).Because blank (5) and patrix (4), counterdie exist frictional force between (6), so, when slide block (7) when the entablature bottom surface of lathe bed (1) does reciprocating linear motion, slide block (7) just drives roll forging piece (3) and patrix (4) is done reciprocal rolling spreading on blank (5), make that blank (5) takes place repeatedly, continuous local deformation, and be configured as forging.
Accompanying drawing 2 is another kind of schemes of roller die forging press of the present utility model.
In accompanying drawing 2, (11) are lathe beds, and (17) are slide blocks.The roll forging piece (3) that patrix (4) will be housed with axle (2) is hinged with the entablature of lathe bed (11).The slide block (17) that counterdie (6) are housed places on the sill of lathe bed (11).Because blank (5) and patrix (4), counterdie exist frictional force between (6), so, when slide block (17) when the sill end face of lathe bed (11) does reciprocating linear motion, will drive patrix (4) and roll forging piece (3) and on blank (5), do reciprocal rolling spreading, make that blank (5) takes place repeatedly, continuous local deformation, and be configured as forging.
What driving slide block (7,17) did reciprocating linear motion can be the machine driving of crank-linkage type, also can be the hydraulic drive of oil cylinder piston formula.
When slide block (7,17) along lathe bed (1, when 11) doing reciprocating linear motion, also can utilize mechanical rotation or hydraulic drive to drive fan-shaped roll forging piece (3) and circular arc patrix (4) is done reciprocal rolling spreading around axle (2) on blank (5).
In the scheme of accompanying drawing 1, between counterdie (6) and lathe bed (1); Or in the scheme of accompanying drawing 2, between counterdie (6) and slide block (17), can install a hydraulic drive or mechanically operated elevating mechanism, make the counterdie (6) can rise and fall, thereby regulate the spreading deflection of blank (5).
From above-mentioned explanation as can be seen: the utility model has following advantage compared with prior art:
1. because circular arc patrix of the present utility model (4) and blank (5) contacted just part, as roll forging, the needed strength that is shaped is very little, so the tonnage of roller die forging press of the present utility model and investment are all smaller.
2. because counterdie of the present utility model (6) has the straight die cavity as die forging, blank (5) through after the reciprocal rolling spreading, just can obtain ratio of precision forging preferably in this die cavity.
Claims (4)
1. roller die forging press that metal forming is used, lathe bed (1 or 11) is arranged, axle (2), the fan-shaped roll forging piece (3) of circular arc patrix (4) is housed, straight counterdie (6) and slide block (7 or 17), it is characterized in that: counterdie (6) is fixed on the end face of lathe bed (1) sill, with axle (2) that fan-shaped roll forging piece (3) and slide block (7) is hinged, this slide block (7) does reciprocating linear motion along the bottom surface of lathe bed (1) entablature, perhaps use axle (2) that fan-shaped roll forging piece (3) is hinged on the entablature of lathe bed (11), counterdie (6) is fixed on the slide block (17), this slide block (17) does reciprocating linear motion along the end face of lathe bed (11) sill, utilize blank (5) with last, counterdie (4,6) frictional force between, make roll forging piece (3) do reciprocal rolling spreading, thereby make blank (5) be configured as forging.
2. press according to claim 1 is characterized in that: what drive that slide block (7,17) does reciprocating linear motion along lathe bed (1,11) is machine driving, or hydraulic drive.
3. press according to claim 1, it is characterized in that: when slide block (7,17) along lathe bed (1, when 11) doing reciprocating linear motion, utilize machine driving or hydraulic drive to drive roll forging piece (3) and patrix (4) is done reciprocal rolling spreading around axle (2).
