Description
Technical field
The utility model relates to a kind of girder construction of ceramic hydraulic press, is specifically related to a kind of lower circular beam structure of large-scale steel wire winding structure brick machine.
Background technology
The steel wire winding prestressed stand generally is assembled into a framework by upper circular beam, lower circular beam and column, then with several layers of compressor wire the framework that is assembled into is tied up securely in aggregatesly, consists of the frame of brick machine.The lower circular beam of present known steel wire winding structure brick machine wherein descends the semicircle cambered surface of circular beam 1 and two sides all to be processed with steel wire trough 2 referring to Fig. 1 and Fig. 2, in order to twine time discharging compressor wire; Principal plane 3 is mainly used in the mounting plate type backing-out punch except both sides are used for installing the left and right column that supports upper and lower circular beam, and board-like backing-out punch is used for connecting the counterdie of brick machine, the effect of playing the filling powder and ejecting the base substrate that has suppressed.
Although this known lower circular beam structure successfully is applied on the ceramic hydraulic press at present, but there is following shortcoming in this structure: 1, along with the maximization of brick machine, this lower circular beam structure is at first too heavy, totally unfavorable for rough-cast, because foundry goods is larger, not only cast risk and casting cost height, also be difficult to guarantee its castability, and processing and cost of transportation height.2, because the central region of circular beam principal plane 3 is high stress areas (the alternate load effect from the prefastening load tension to the service load compression is born in this zone) under the wrapped brick-press, so guarantee its quality when should the zone requiring casting, avoid various casting flaws as far as possible, otherwise will jeopardize the fatigue life of brick machine, and this known lower circular beam exactly produces casting flaw easily in this high stress areas, this is because generally all adopt vertical casting during the casting of this lower circular beam, be arc surface down, principal plane up, and at principal plane feeding head is set, the result causes this zone casting flaw to occur easily, shrinkage porosite for example, the defective such as crack easily when slag inclusion and gas cutting rising head, this beam body for the wrapped brick-press that bears alternate load is totally unfavorable.
The utility model content
The purpose of this utility model is to provide circular beam under a kind of combined type for the deficiencies in the prior art part, and it not only is conducive to rough-cast but also save cost of transportation.
For achieving the above object, the utility model adopts following technical scheme:
Circular beam under the combined type comprises circular beam, and the top of described lower circular beam is principal plane, and arc surface and the left and right sides of described lower circular beam are provided with steel wire trough; Described lower circular beam forms by fitting before and after front lower circular beam and the rear lower circular beam, and the binding face place between front lower circular beam and rear lower circular beam is provided with and is connected and fixed assembly; Reaching the top of described front lower circular beam is front principal plane, and arc surface and the left and right sides of described front lower circular beam are provided with steel wire trough; The top of described rear lower circular beam is rear principal plane, and arc surface and the left and right sides of described rear lower circular beam are provided with steel wire trough.
As preferably, the thickness of described front lower circular beam and rear lower circular beam is substantially identical.
As preferably, the described assembly that is connected and fixed comprises: a key is arranged in the location shallow bore hole at front lower circular beam and rear lower circular beam binding face place; With one group of clamping screw, run through front lower circular beam and rear lower circular beam and be arranged in the left and right sides of key.
As preferably, described key is square button.
As preferably, the length of side of described square button is no less than 1/5th of lower circular beam height.
As preferably, described key is solid construction.
The utility model is because two beam bodies independently before and after being split as, and the present situation of make the lower circular beam weight of large-scale wrapped brick-press too heavy, casting manufacturability is poor and casting flaw is many is thoroughly improved: on the one hand, foundry goods is little by largeization, easier casting; On the other hand, the single beam body of this new construction can adopt horizontal casting when casting, blank keeps flat when namely casting, binding face up, and at binding face feeding head is set, and what of molten steel amount when casting like this, the feeding effect of rising head etc. can directly not affect the castability of the high stress areas such as principal plane of lower circular beam, avoid casting flaw, thereby improved the fatigue strength of time circular beam.In addition, the utility model has also been saved cost of transportation.
