Description

The train bearing seal closure adds the tool that repairs a die
Technical field:
The utility model relates to a kind of seal closure repairing mould, is specifically related to a kind of train bearing seal closure and adds the tool that repairs a die.
Background technology:
The railway freight train generally uses the bearing seal cover that freight car bearing is carried out seal protection at present.For guaranteeing that train can normally move safely, the bearing seal cover need reach very high technical standard, in case can not reach technical standard, just the bearing seal cover need be changed or is added and repair.The railway freight-car seal closure is many with the thick steel plate of No. 20 2.5mm and adopt the special dies compacting to form, and cylindrical and bearing block closely cooperate, and is used for anti-gray, waterproof to keep bearing to clean, and during every train periodic inspection, must pull down inspection bearing ruuning situation to seal closure.Because the seal closure diameter is bigger, seal closure can produce bigger plastic deformation in unloading process can't use seal closure, needs to change Xinmi City's sealing cover or old seal closure added to repair the back and use.Owing to the cost of changing Xinmi City's sealing cover is higher, all be old seal closure to be added by general elastic mould repair the back use in actual the use.And the punch of general elastic mould (patrix) is flexible, its outside dimension is adjustable, the outside dimension of die (counterdie) is slightly larger than the outside dimension of seal closure, and die is fixed, therefore, utilizing general elastic mould that seal closure is added repaiies, make the outside dimension super large of seal closure easily, reduced the yield rate of seal closure, the yield rate that makes seal closure only is 50~60%, all the other underproof seal closures can only increase production cost as waste disposal.
The utility model content:
The purpose of this utility model is for after solving the dismounting of train bearing seal closure, add the seal closure outside dimension super large that repairs with general elastic mould, can not recover standard size, thereby a kind of train bearing seal closure that causes the seal closure yield rate is low, production cost is high problem to provide adds the tool that repairs a die.It is made up of die shank 1, pressure cap 2, guide pillar 3, spring 4, patrix 5, platen 6, counterdie 8, pressing plate 9, rag iron spring 10, base plate 11; The upper end of patrix 5 is equipped with pressure cap 2 and is fixedlyed connected with the screw rod 1-1 of die shank 1 lower end, the lower end of patrix 5 has female cone hole 5-1, in the axis hole of patrix 5 upper ends guide pillar 3 is housed, the lower end of guide pillar 3 and platen 6 are fixedlyed connected by screw thread, spring 4 is equipped with in the outer end of guide pillar 3, the outer wall of counterdie 8 has radial opening 8-1, the upper end of counterdie 8 has the identical outer conical surface 8-2 of female cone hole 5-1 tapering with patrix 5, the female cone hole 5-1 of patrix 5 matches with the outer conical surface 8-2 of counterdie 8, the lower end of counterdie 8 is installed in the groove of base plate 11, pressing plate 9 is housed in the cannelure of counterdie 8, rag iron spring 10 is housed in the annular groove of pressing plate 9.
The utlity model has following beneficial effect: one, the lower end of patrix has the female cone hole, and the upper end of counterdie has and the identical outer conical surface of patrix female cone hole tapering, and the counterdie outer wall has radial opening, makes counterdie become the elasticity die.When the female cone hole of patrix cooperates with the outer conical surface of counterdie, can make that the seal closure oversize dwindles in the counterdie, use general elastic mould that seal closure is added to repair the problem that the seal closure that produces the outside dimension super large is repaired thereby solved.Facts have proved, use this to add the tool that repairs a die and to make the repair rate of seal closure outside dimension super large reach 100%, greatly reduce production cost.Two, this adds the tool that repairs a die and has advantage simple in structure, that use is easy to adjust, result of use good, the seal closure repair rate is high.
Description of drawings:
Fig. 1 is a whole cross-sectional view of the present utility model, and Fig. 2 is the plan structure schematic diagram that counterdie 8, pressing plate 9 and rag iron spring 10 are assembled together.
The specific embodiment:
The specific embodiment one: in conjunction with Fig. 1, Fig. 2 present embodiment is described, present embodiment is made up of die shank 1, pressure cap 2, guide pillar 3, spring 4, patrix 5, platen 6, counterdie 8, pressing plate 9, rag iron spring 10, base plate 11; The upper end of patrix 5 is equipped with pressure cap 2 and is fixedlyed connected with the screw rod 1-1 of die shank 1 lower end, the lower end of patrix 5 has female cone hole 5-1, in the axis hole of patrix 5 upper ends guide pillar 3 is housed, the lower end of guide pillar 3 and platen 6 are fixedlyed connected by screw thread, spring 4 is equipped with in the outer end of guide pillar 3, the outer wall of counterdie 8 has radial opening 8-1, the upper end of counterdie 8 has the identical outer conical surface 8-2 of female cone hole 5-1 tapering with patrix 5, the female cone hole 5-1 of patrix 5 matches with the outer conical surface 8-2 of counterdie 8, the lower end of counterdie 8 is installed in the groove of base plate 11, pressing plate 9 is housed in the cannelure of counterdie 8, rag iron spring 10 is housed in the annular groove of pressing plate 9.
The specific embodiment two: in conjunction with Fig. 1 present embodiment is described, the height h of the outer conical surface 8-2 of the counterdie 8 of present embodiment is less than the height H of the female cone hole 5-1 of patrix 5.Adopt this structure can guarantee that the outer conical surface 8-2 of counterdie 8 matches with the taper seat of the female cone hole 5-1 of patrix 5.Other composition and annexation are identical with the specific embodiment one.
During use, the seal closure 7 that will repair is put on the pressing plate 9, by rotation patrix 5 and pressure cap 2, adjust the distance between die shank 1 and the platen 6, when the distance between patrix 5 and the platen 6 is adjusted to optimal values, patrix 5 moves downward, just match with the outer conical surface 8-2 of counterdie 8 in the upper end of the female cone hole 5-1 of patrix 5, the outside dimension of seal closure 7 super larges is narrowed down to the size of regulation, again will be the seal closure 7 of reduced outside diameter size super large utilize general elastic mould to continue to add again to repair, it is qualified to reach seal closure 7.
