Abstract
The utility model discloses a press body structure of a gap frame press. A press body comprises a workbench. A sliding block is arranged above the workbench. The two sides of the stroke of the sliding block are provided with guide rails respectively. The sliding block can move linearly in a reciprocating mode between the two guide rails and along the guide rails. The two sides of the press body are respectively provided with a side board. A reinforcing connecting board is further connected between the two side boards, detachably fixed to the portion above a throat opening of the press body and in the same height with the lower portions of the guide rails. A front opening of the two side boards of the press body is effectively fixed through the reinforcing connecting board, so that when the press body receives lateral force and the side boards expand outwards and are deformed due to press body deformation, lateral inclination angle deformation is reduced to a great extent through the reinforcing connecting board. When the rigidity of the press body is good, lateral inclination angle deformation can be easily controlled within one minute of arc and the effect is remarkable. According to the press body structure of the gap frame press, the guiding accuracy of the sliding block can be improved, so that the properties of the machining accuracy and the like of the whole press are improved.

The technical scheme that the utility model is taked is specially: a kind of airframe structure of gap-framepress, fuselage comprises workbench, workbench top is provided with slide block, and the both sides of ram travel are separately installed with guide rail, and slide block can do straight reciprocating motion along guide rail between two side rails;
Fuselage both sides are respectively equipped with side plate, are also connected with reinforcement connecting plate between biside plate, and reinforcement connecting plate is removably fixed in the top of fuselage aditus laryngis, and are positioned at the setting height(from bottom) place of guide rail bottom.
In the utility model, reinforcement connecting plate is avoiding, after the certain space of slide block operation, being arranged on the both sides of fuselage, and Strengthenable fuselage is due to the deformation rigidity that affected by side force to cause.
In the situation that guaranteeing not affect slide block operation, the reinforcement connecting plate two ends in the utility model can be individually fixed on the side plate of fuselage both sides, and reinforcement connecting plate plane vertically arranges perpendicular to biside plate.
For the existing forcing press that adds production that installed, its lateral plate structure is set, in the time that reinforcement connecting plate is installed, the side plate of fuselage both sides is also fixedly connected with respectively stiffening plate, reinforcement connecting plate two ends are fixedly connected with respectively the stiffening plate of a side, can reach the effect of fuselage reinforcement, not interfere the operation of slide block simultaneously.
Further, in the production installation process of forcing press, can, to stiffening plate and side plate die sinking simultaneously, the stiffening plate of moulding and side plate be integrated, can optimize the reinforcing effect of fuselage.
What the utility model can carry out maximum possible by the size of change reinforcement connecting plate and structure reduces fuselage lateral tilt angular deformation; The distortion of fuselage lateral angle itself is less while having met required precision, this reinforcement connecting plate can use flexibly, also detachably gets off.
The beneficial effects of the utility model are: fuselage has been installed reinforcement connecting plate, the biside plate front openings of fuselage is effectively fixing, when fuselage is in the time that the side plate that is subject to side force and cause due to frame deflection extends out distortion, because the existence of reinforcement connecting plate can significantly reduce its lateral tilt angular deformation.When stiffness of fuselage is better, can be easy to control lateral tilt angular deformation in 1 jiao point; Particularly progressive die multistation adds man-hour, and opposing has significant effect because unbalance loading makes the distortion that extends out of fuselage biside plate, has improved the guiding accuracy of slide block, and then has improved the performance such as machining accuracy of complete machine.
