Abstract
The utility model relates to a flash removing mechanism for large-blade die forgings, which has the advantages of simple structure, convenient use, strong universality and high production efficiency. The mechanism comprises a trimming die, wherein the trimming die comprises an upper die seat and a lower die seat; the upper die seat is provided with a convex die through a convex die fixing plate; and the lower die seat is provided with a concave die through a concave die fixing plate. The mechanism is characterized by also comprising a transition plate and an edge removing plate; the transition plate is embedded on the upper die seat; hydraulic oil cylinders are arranged above the transition plate and in the upper die seat; and the transition plate is connected with the flash removing plate through a sleeve barrel and screws.
Description
(1) technical field
The utility model relates to the large-blade die forging piece field shaping technique, is specially a kind of edge flashing and off-clipping mechanism that is used for large-blade die forging piece.
(2) background technology
Overlap after conventional the forging is removed only to rely on and can be taken off overlap with aids such as crow bars manually, also has by the off-clip pawl to remove overlap.Because the length of big blade is generally more than 1 meter, it forges back overlap shape, volume is big, removes and can't realize with prizing manually; And the overlap distortion is serious behind the big blade mould forging, the pole of figure is irregular, and conventional off-clip pawl also is difficult for installing and using, and makes that the removal difficulty of overlap is big behind the big blade mould forging, and efficient is low; And the blade forging mostly is many kinds, small lot batch manufacture, and adopting conventional off-clip pawl to carry out off-clip need be according to the off-clip pawl of blade construction design specialized, and off-clip pawl structure is complicated, and it is big to manufacture difficulty, and its production cost is also higher.
(3) summary of the invention
At the problems referred to above, the utility model provides a kind of edge flashing and off-clipping mechanism that is used for large-blade die forging piece, and it is simple in structure, and is easy to use, highly versatile, production efficiency height.
Its technical scheme is such, it comprises edger, described edger comprises upper bolster and die shoe, by punch retainer punch is installed on the described upper bolster, described die shoe is equipped with die by die block, it is characterized in that: it also comprises rebound, off-clip plate, and described rebound insert is in described upper bolster, in described rebound top and the described upper bolster hydraulic jack is installed, described rebound is connected described off-clip plate by sleeve with screw.
It is further characterized in that: the compression spring is installed in the described punch retainer; Described compression spring is positioned at described rebound bottom; Described die block is installed on web beam; Described web beam is installed on described die shoe.
A kind of edge flashing and off-clipping mechanism that is used for large-blade die forging piece of the present utility model, it is installed in the side cut die holder, promotes rebound and off-clip plate and moves downward and carry out removing of overlap by being installed on hydraulic jack in the upper bolster, and is simple in structure, easy to install, high efficiency; Its off-clip plate can be according to the corresponding design of blade construction, and is more convenient than the making of off-clip pawl in the past, also reduced production cost.
(4) description of drawings
Fig. 1 is a kind of structural representation that is used for the edge flashing and off-clipping mechanism of large-blade die forging piece of the utility model.
(5) specific embodiment
See Fig. 1, the utility model comprises edger, and edger comprises upper bolster 1 and die shoe 13, by punch retainer 2 punch 5 is installed on the upper bolster 1, and die shoe 13 is equipped with die 10 by die block 11; The utility model structure also comprises rebound 4 and off-clip plate 9, rebound 4 inserts are in upper bolster 1, in rebound 4 tops and the upper bolster 1 hydraulic jack 7 is installed, rebound 4 is connected off-clip plate 9 by sleeve 6 with screw 8, between rebound 4, sleeve 6 and the off-clip plate 9 for being rigidly connected.Compression spring 3 is installed in the punch retainer 2; Compression spring 3 is positioned at rebound 4 bottoms; Die block 10-is loaded on web beam 12; Web beam 12 is installed on die shoe 13.
During use, the forging part of band overlap steadily is rotated on the trim die 10, guarantee that the applying of forging and mould is good, the starting pressure machine, utilize punch 5, die 10 is cut edge, cut edge back punch 5 in following forcing press backhaul process, the hydraulic jack 7 promotion rebounds 4 that are installed in the upper bolster 1 move downward, rebound 4 is delivered to power on the off-clip plate 9 by sleeve 6 simultaneously, finish the off-clip operation smoothly, at this moment, be installed in compression spring 3 in the punch retainer 2 under huge bounce effect with rebound 4 together with sleeve 6, the off-clip plate is jack-up upwards together, be returned to free state, promptly finished an off-clip circulation.In whole off-clip process, sleeve 6 had both played the effect of power transmission, had played the guide effect in the motion process again.
