Abstract
The utility model relates to a lower die holder of a thermal sizing die for a hydraulic press die forging. The left side and the right side of a top plate groove (10) in a thermal sizing lower die holder body (1) are respectively provided with a groove communicated slots (15a and 15b) which lead to the edges of the die holder body (1); and the bottom surfaces of the groove communicated slots (15a and 15b) are flush with the bottom surface of the top plate groove (10). In work, the two groove communicated slots (15a and 15b) enable the top plate groove (10) to be communicated with the left outer side and the right outer side of the die holder body (1), so that a blow pipe can be inserted into the groove communicated slot (15a/15b), and oxide skins accumulated in the top plate groove (10) can be blown out from one end to the other end, thereby solving the problem that the oxide skins are difficult to remove.
Description
Technical field
The utility model relates to the die holder of the hydraulic press thermal recalibration bed die of forging part, die shoe is used for stationary heat and proofreaies and correct counterdie.
Background technology
The forging part materials such as bent axle are the carbon alloy structural steel, large-scale hotdie forging press is automatic production line, productive temp is very fast, and the die-forging forming temperature reaches 1250-1300 ℃, and Tc reaches about 1000 ℃, in forming process, the oxide skin Surface Creation one deck densification of the forging whole body, about the about 0.5-0.8mm of thickness, during the shape of school, hot forging is surperficial to be contacted fully with the Correction Die die cavity, temperature drop is very fast, and oxide skin generation explosion falls in the type groove of thermal recalibration bed die.In producing continuously, thermal recalibration bed die and die holder temperature can be raised to about 300 ℃, make the distortion of rising of mold tooling generation heat, and simultaneously, being arranged on the interior top board 21 of thermal recalibration bed die 2 type grooves in use also can the different flexural deformation of occurrence degree.Unimpeded in order to guarantee that top board 21 moves in thermal recalibration bed die 2, the size of top board 21 chute a in the thermal recalibration bed die type groove is loosely more a lot of than top board 21 sizes, namely be larger matched in clearance, quite a few oxide skin can fall into along the top board chute a on the thermal recalibration bed die in the top board groove 10 on the thermal recalibration die shoe 1 like this, can't in time remove, the oxide skin of piling up causes the top bar 13 on top board 21 and the die shoe to be difficult to reset, put into hot straightening mold when hot forging and carry out timing, weigh easily the situation with the bending forging wounded, cause forging to scrap.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art pair
The die shoe of hydraulic press forging part hot straightening moldImprove, existing
The die shoe of hydraulic press forging part hot straightening moldImprove on the architecture basics, the oxide skin in the die shoe top board groove that causes to fall and break can in time be removed.
The utility model offers the top board groove 10 that cooperates with top board 21 in the thermal recalibration bed die 2 at the middle part of thermal recalibration counterdie pedestal 1, offer the jogger hole 12 that cooperates with push rod 31 in the press bed 3 in top board groove 10 bottom surfaces, in top board groove 10, be provided with top bar 13, fore-set 14 fixing on top bar 13 lower surfaces cooperates with push rod 31, the top board 21 that top bar 13 promotes in the thermal recalibration bed die 2 moves up and down, it is characterized in that having the groove groove 15a that leads to die holder body 1 limit in the left and right sides of thermal recalibration counterdie pedestal 1 inside ceiling panel groove 10,15b, groove groove 15a, the bottom surface one of 15b bottom surface and top board groove 10 is flat.
The utility model is simple in structure, and is easy to process.Two groove groove 15a, 15b make top board groove 10 communicate with the outside about die holder body 1 during work, insert on the groove groove 15a/15b with regard to available blower like this, the oxide skin that is deposited in the top board groove 10 is from one end to the other side blown out, effectively blow off oxide skin, solve oxide skin and remove hard problem.
The utility model is verified through batch product, and successful is produced 500-600 spare product before improving, and with regard to the correction bed die being unloaded down die shoe is carried out the descaling processing, and whole production line is stopped production, and has not only wasted the time but also wasted the man power and material.Can blow down at any time oxide skin after the improvement, when changing product or mould, thoroughly descaling once gets final product, and has improved widely production efficiency, has reduced operator's labour intensity.

The specific embodiment
The utility model thermal recalibration die shoe, offer the top board groove 10 that cooperates with top board 21 in the thermal recalibration bed die 2 at the middle part of counterdie pedestal 1, offer the jogger hole 12 that cooperates with push rod 31 on the press bed 3 in top board groove 10 bottom surfaces, in top board groove 10, be provided with top bar 13, the fore-set 14 of fixedly putting on top bar 13 lower surfaces cooperates with push rod 31, the top board 21 that top bar 13 promotes on the thermal recalibration bed die moves up and down, have the groove groove 15a that leads to die holder body 1 limit in the left and right sides of thermal recalibration counterdie pedestal 1 inside ceiling panel groove 10,15b, groove groove 15a, the bottom surface one of 15b bottom surface and top board groove 10 is flat, make top board groove 10 be spacious logical state at length direction, in process of production, when top bar 13 upwards moved, available blower blowing blew out oxide skin.
