Description

The shaping mould of hammered work intermediate plate hot extrusion through hole
Technical field
The utility model relates to the mould that a kind of Forging Technology is used, and specifically is meant the shaping mould of hammered work intermediate plate hot extrusion through hole.
Background technology
Along with the development of prestressing technique, intermediate plate anchor proportion in prestress engineering is increasing, and consumption sharply increases, and the time anchor clipper most important in the intermediate plate anchor, that consumption is maximum.Anchor clipper is used for clamping presstressed reinforcing steel when the deformed bar of anchor prestressed concrete member, and he is widely used in the construction such as different types of rridges road skyscraper.At present each prestressing force manufacturer to produce the traditional handicraft of anchor clipper be to adopt round bar, split end face, turning hole, boring, finish turning endoporus then, process hole taper, attack internal thread, the car external taper, dissect, operations such as heat treatment and sandblast.Blasting treatment process after the heat treatment is little to the impact and the shear action power of surface of the work, causes inefficiency, and the workpiece surface quality after the processing is relatively poor.
The utility model content
The purpose of the utility model is to provide the shaping mould of hammered work intermediate plate hot extrusion through hole, cooperates processing technology, substitutes the method that the ground tackle work clip sheet is made in machined, reaches to reduce raw-material consumption, reduces machining processes, the purpose that reduces cost.
The purpose of the utility model realizes through following technical proposals:
The shaping mould of hammered work intermediate plate hot extrusion through hole; Comprise and be connected the cope match-plate pattern on the punch press and be positioned at the lower bolster under the cope match-plate pattern; On described cope match-plate pattern, die shank is installed, punch is installed on die shank, two discharge arms are installed on lower bolster; Stripper is installed on discharge arm; On the discharge arm between stripper and the lower bolster, be set with the spring that is in compressive state, punch case is installed on stripper, the die that is complementary with punch also is installed on lower bolster.During use, the workpiece of mould forging is put into die, punch press drives cope match-plate pattern, and cope match-plate pattern drives punch and moves downward; Punch passes the through hole of punch case earlier, could continue then to move downward, and workpiece is forged extruding; After accomplishing extruding, the spring that is in compressive state drives stripper and moves upward, when reaching the extreme higher position; Punch continues to move upward, and workpiece is the disengaging punch under the effect of stripper, after workpiece is ejected; Can take out workpiece, new workpiece is installed, process next time.With respect to present technology, the mode that adopts mould to forge is processed into the through hole of ground tackle work clip sheet, has replaced present bore process; Practiced thrift raw-material use amount; Relation according to the cumulative volume of the volume of work clip sheet through hole and work clip sheet can be learnt, compares present technology, the consumption that can save material; Reduce machining processes, reach about 20% the purpose of reducing cost.
On described lower bolster, die holder is installed; In die holder, be set with the die circle stress; In the die circle stress, be set with die, die is connected through taper fit with the die circle stress, and the die circle stress is fixedly connected on the die holder through the die locking nut; The inner upper surface of die holder is recessed to form annular groove downwards, in groove, is placed with the perforation pad.Saying that further die belongs to running stores, is the independent original paper that can change; Die is connected with the die circle stress through taper fit, and the die circle stress is that die provides anti-impact force, and the die circle stress is fixedly connected on the die holder through the die locking nut; So, not only die can be when die damages, changed, and the model of processing work can be enlarged; The die holder of die bottom is provided with groove, and inside grooves is placed with a perforation pad, and its effect is that punch can stamp out through hole fully; Reduce the impact of punch press simultaneously, guarantee that the punching press of through hole is accomplished die holder.
Be provided with the through hole that is positioned under the punch on said base plate, die holder and the perforation pad.
Said punch is fixedly connected on the die shank through the punch locking nut, and said punch locking nut is provided with water pipe head.Say that further because the in running order time of punch is longer, its heat that receives is bigger; In order to lower the temperature to punch, the punch locking nut is provided with water pipe head, and water pipe head connects cooling fluid; The normal working temperature that can keep punch is avoided the too high problem of bringing of temperature.
The utility model compared with prior art has following advantage and beneficial effect:
The shaping mould of 1 the utility model hammered work intermediate plate hot extrusion through hole, with respect to present technology, the mode that adopts mould to forge is processed into the through hole of ground tackle work clip sheet; Replaced present bore process, practiced thrift raw-material use amount, can learn according to the relation of the cumulative volume of the volume of work clip sheet through hole and work clip sheet; Compare present technology; The consumption that can save material reduces machining processes, reaches about 20% the purpose of reducing cost;
The shaping mould of 2 the utility model hammered work intermediate plate hot extrusion through holes, maximum characteristics are after punch case cooperates earlier centering, to get into the die shaping again of boring a hole earlier through punch, prevent that product is eccentric; Height can fix after adjustment, and workpiece reaches technological requirement after the assurance shaping, and the punch band the workpiece rising after the shaping; Punch separates discharging and accomplishes with punch case behind the desired location; Take out workpiece, through automatic cooling system mould is cooled off simultaneously, mould parts is realized changing fast;
The shaping mould of 3 the utility model hammered work intermediate plate hot extrusion through holes, is made simple, cooling automatically, lubricated, discharging, die change time≤10min at novel structure, reaches 10000/ the service life of punch.
