Description
Technical field
The utility model relates to a kind of friction press circle mould mould bases.
Background technology
There is following defective in existing friction press circle mould mould bases: (one) counterdie backing plate is connected with die shoe and is connected up and down with positioning convex by locating slot, between counterdie backing plate and finish forge counterdie, small raft is set, in forging process, small raft, counterdie backing plate and die shoe all only are subject to a hitting power vertically downward, after using a couple of days, small raft will produce cracking or distortion, need to often change or reprocess small raft (monthly average is changed 3 of small rafts), thereby have a strong impact on forging and expended more auxiliary material; (2) due to the hardness of the die shoe hardness less than small raft, and the die shoe outside dimension is more than 4 times of its gauge, when the hitting power that is subject to vertically downward, die shoe will form the plastic deformation of central compression, cylindrical tension, its baseplane is subjected to the impact of deformation to form arch (namely the centre is high, surrounding is low), cause die shoe and counterdie backing plate contacted plane to form the circular arc depression thereupon, use if mould bases is long-term, the deformation of die shoe and counterdie backing plate increases the weight of even to bring disaster to the damage of equipment and working plate until damage thereupon; (3) finish forge counterdie and small raft are connected by locating slot and positioning convex, because the finish forge counterdie has locating slot at its baseplane central part, make its strength decreased, bottom because of locating slot has the stress that produces after machined and heat treatment again, thereby when causing forging, cracking easily appears in mould, reduces the mold use life-span.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of not yielding, long service life, friction press circle mould mould bases that cost is low are provided.
the technical scheme that its technical problem that solves the utility model adopts is: a kind of friction press circle mould mould bases, comprise die shoe, the counterdie backing plate, the finish forge counterdie, counterdie circle stress and counterdie trim ring, described counterdie backing plate is fixed on the die shoe upper surface by lower joint chair, has a conical through-hole on described lower joint chair, described counterdie backing plate has the profile that matches with the upper conical shape of through holes of lower joint chair, described lower joint chair upward coordinates by adopting conical surface interference outside being enclosed within the counterdie backing plate, described lower joint chair and die shoe are by locating slot and positioning convex matched in clearance and fix by screw, has a groove on described counterdie backing plate upper surface, being placed with backing plate in this groove inserts, described finish forge counterdie is fixed on the upper surface of counterdie backing plate, insert with backing plate with the counterdie backing plate and contact in this finish forge counterdie bottom surface, and this finish forge counterdie bottom surface has positioning convex, counterdie backing plate upper surface has locating slot, finish forge counterdie and counterdie backing plate are by positioning convex and locating slot matched in clearance, has mold cavity on the upper surface of described finish forge counterdie, described counterdie circle stress is enclosed within on finish forge counterdie lateral surface and coordinates by adopting conical surface interference, described counterdie trim ring is enclosed within on counterdie circle stress lateral surface and coordinates by adopting conical surface interference, described counterdie trim ring is fixedly connected with lower joint chair by screw.
The baseplane of described counterdie backing plate is higher than the baseplane of lower joint chair, and the difference in height scope between this two baseplane is 0.6～1mm.
The outside dimension of described counterdie backing plate and the ratio range of its gauge are 2～2.3.
Described backing plate is inserted together with counterdie backing plate interference fit is embedded in.
beneficial effect: (one) lower joint chair and counterdie backing plate adopt adopting conical surface interference to coordinate, the baseplane of the baseplane of counterdie backing plate and lower joint chair maintains the distance of 0.6mm～1mm, when mould bases is subject to vertically downward hitting power, the counterdie backing plate is done a small amount of movement downwards, to strengthen the magnitude of interference of itself and lower joint chair cone match, thereby increase the radially prestressing force between two parts, because two parts adopt cone match, therefore the hitting power that the counterdie backing plate can be born resolves into a component vertically downward and a component vertical with the conical surface, radially prestressing force between two parts can be eliminated most conical surface vertical stress component, the ratio of counterdie backing plate outside dimension and its gauge is controlled between 2～2.3, can reduces the strain of counterdie backing plate, lower joint chair and die shoe are by locating slot and positioning convex matched in clearance and fix by screw, above improvement has all extended the service life of counterdie backing plate, lower joint chair and die shoe simultaneously.
(2) the finish forge counterdie is cancelled locating slot, and the locating slot of using instead on positioning convex and counterdie backing plate is connected, thereby has improved the intensity of finish forge counterdie, has extended its service life.
(3) the small raft structure in the former mould bases of cancellation, adopt backing plate to insert together with counterdie backing plate interference fit is embedded in, and when the finish forge counterdie bears hitting power, can delay the plastic deformation of counterdie backing plate and the service life of prolongation finish forge counterdie.
(4) finish forge counterdie, counterdie circle stress and counterdie trim ring are combined into a cover edge formula mould, the counterdie trim ring by screw fastening on lower joint chair, the conical surface that the pressure that produces makes this cover edge formula mould pass through separately forms interference fit, and produce one to the radially prestressing force of mold center, ftracture in early days to prevent the finish forge counterdie.
In sum: coming into operation of this mould bases, can make the mould bases life-span improve nearly 2 times, the finish forge counterdie improves 10%～15% service life; Due to the small raft structure of having cancelled former mould bases, correspondingly saved a lot of human and material resources and time, every cover mould bases can be saved small raft cost 2300 yuan of left and right per month.
