Description
Technical field
The utility model belongs to field of metal material heat processing technology, is specifically related to a kind of hot Counterboring apparatus that improves mandrel rigidity.
Background technology
In field of metal material heat processing technology, forge the conventional core axial hole machining technique of cylindrical shape forging. While using core axial hole machining, along with the attenuate of cylindrical shape forging wall thickness, inside and outside footpath expands simultaneously, highly has increased slightly. In order to obtain the forging that inwall is more smooth, axle diameter should increase with borehole enlargement conventionally.
Along with further developing of cylindrical shape forging the Enlargement Tendency, cylindrical shape diameter of forgings is increasing, highly more and more higher. Be limited to the consideration of equipment and economic aspect, the mandrel that reaming is used can not infinitely increase with the diameter of cylindrical shape forging, therefore, when forging height and the larger cylindrical shape forging of diameter, and the axle diameter of selecting is time relatively less than normal, occurs sometimes because the deficiency of mandrel rigidity causes the bell-mouthed defect of cylindrical shape forging.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of hot Counterboring apparatus that improves mandrel rigidity is provided, and solves prior art due to mandrel insufficient rigidity, can cause the technical problem of cylindrical shape forging horn mouth defect in reaming process.
The utility model is achieved through the following technical solutions:
A hot Counterboring apparatus that improves mandrel rigidity, is characterized in that: this device is made up of upper anvil, mandrel, a pair of saddle support and mandrel rigidity reinforcement plate; Described saddle support is made up of saddle support upper bracket and saddle support undersetting; Described saddle support upper bracket upper end has the half slot of placing described mandrel, and described saddle support upper bracket middle part has the narrow rectangular channel of placing described mandrel rigidity reinforcement plate, and described narrow rectangular channel and described half slot communicate; Described saddle support undersetting has the wide rectangular channel of placing saddle support upper bracket; Described mandrel rigidity reinforcement plate is a rectangular slab.
Further, the length of described mandrel rigidity reinforcement plate is equal to or slightly less than the length of described mandrel.
Further, while described mandrel rigidity reinforcement plate being inserted in the narrow rectangular channel of two described saddle support upper brackets, the upper end of described mandrel rigidity reinforcement plate contacts with described mandrel, and lower end contacts with the bottom of the narrow rectangular channel of described saddle support upper bracket.
The utility model compared with prior art, owing to having set up mandrel rigidity reinforcement plate below mandrel by saddle support, the lower flexure strain of mandrel middle part under press effect can be subject to the support of mandrel rigidity reinforcement plate, be equivalent to increase the rigidity of mandrel, avoid cylindrical shape forging in reaming process, to produce bellmouth orifice defect, can reduce axle diameter, reduced production cost simultaneously.

Detailed description of the invention
The exemplary embodiments that embodies the utility model feature & benefits, describes in detail in the following description in connection with accompanying drawing. Be understood that the utility model can have various variations on different embodiment, it neither departs from protection domain of the present utility model, and explanation wherein and to be shown in be the use when explaining in essence, but not in order to limit the utility model.
A cylindrical shape forging finished size is as follows: external diameter Φ 2880mm, internal diameter Φ 2435mm, high 3220mm, select the mandrel of diameter of phi 1120mm, after adopting the reaming of existing core axial hole machining device, there is horn mouth defect, as shown in Figure 1, cannot meet subsequent technique requirement. Use after following device of the present utility model and corresponding technique, axle diameter does not change, but has avoided horn mouth defect, has met subsequent technique requirement.
As shown in Figures 1 to 7, a kind of hot Counterboring apparatus that improves mandrel rigidity, is made up of upper anvil 2, mandrel 4, a pair of saddle support 3 and mandrel rigidity reinforcement plate 7; Described saddle support 3 is made up of saddle support upper bracket 31 and saddle support undersetting 32; Described saddle support upper bracket 31 upper ends have the half slot 311 of placing described mandrel 4, and described saddle support upper bracket 31 middle parts have the narrow rectangular channel 312 of placing described mandrel rigidity reinforcement plate 7, and described narrow rectangular channel 312 and described half slot 311 communicate; Described saddle support undersetting 32 has the wide rectangular channel 321 of placing saddle support upper bracket 31; Described mandrel rigidity reinforcement plate 7 is a rectangular slab.
The length L 2 of described mandrel rigidity reinforcement plate 7 is equal to or slightly less than the length L 1 of described mandrel 4.
When narrow rectangular channel 312 that described mandrel rigidity reinforcement plate 7 is inserted into two described saddle support upper brackets 31 is interior, the upper end of described mandrel rigidity reinforcement plate 7 contacts with described mandrel 4, and lower end contacts with the bottom of the narrow rectangular channel 312 of described saddle support upper bracket 31.
The concrete steps of the utility model using method are:
(1) a pair of saddle support undersetting 32 is placed in respectively to press bed correct position, more a pair of saddle support upper bracket 31 is placed in respectively in the wide rectangular channel 321 of saddle support undersetting 32;
(2) insert in the hole of cylindrical shape forge piece blank reheating 5 with mandrel 4, and by mandrel 4 two ends builts in the half slot 311 of a pair of saddle support upper bracket 31;
(3) press down with the press 1 of upper anvil 2, under the cooperation of manipulator, start core axial hole machining technique;
(4) when the internal diameter of cylindrical shape forge piece blank reheating 5 expands to when being greater than mandrel 4 diameter D and adding the height H of saddle support rigidity reinforcement plate 7 and be enough to hold the two, mandrel rigidity reinforcement plate 7 is inserted in the narrow rectangular channel 312 of two saddle support upper brackets 31, the upper end of mandrel rigidity reinforcement plate 7 contacts with mandrel 4, and lower end contacts with the bottom of the narrow rectangular channel 312 of saddle support upper bracket 31;
(5) continue core axial hole machining technique, until cylindrical shape forging finished size.
In described technical process (4), because mandrel 4 lower ends have increased mandrel rigidity reinforcement plate 7, the lower flexure strain of mandrel 4 middle parts under press effect can be subject to the support of mandrel rigidity reinforcement plate 7, its downwarp amount can reduce greatly, be equivalent to increase the rigidity of mandrel 4, can have avoided cylindrical shape forging to produce bellmouth orifice defect.
The utility model can specifically be implemented in a variety of forms and not depart from spirit or the essence of invention; so be to be understood that; above-described embodiment is only preferred embodiment of the present utility model; and should in claim limited range, explain widely, the variation and the remodeling that therefore fall in claim or its equivalent scope all should be considered as protection domain of the present utility model.
