Abstract
The invention relates to a hollow pin shaft of a cubic hinge press, which comprises an upper hollow pin shaft and a lower hollow pin shaft which is butt-jointed with the upper hollow pin shaft. The two hollow pin shaft are respectively inserted into pin shaft holes of a hinged beam from upside and lower side; a core shaft penetrates between the upper hollow pin shaft and the lower hollow pin shaft; the two ends of the upper hollow pin shaft and the lower hollow pin shaft are provided with an upper end plate and a lower end plate which are equipped with central holes; and screws penetrate through the central holes of the upper end plate and the lower end plate and are connected with the core shaft. According to a bending resistance section modulus formula, under the condition of meeting an allowable shearing strength of the pin shaft, the hollow pin shaft is lighter than a solid pin shaft, moreover, the whole pin shaft is divided into two hollow pin shafts, thus, the weight of the pin shaft is reduced by half again. Therefore, the invention is extremely convenient for both installation and maintenance, reduces the pin shaft weight and size to a maximum degree, and guarantees the shearing resistance of the pin shaft.
Description
Technical field
The present invention relates to the synthetic equipment field of super-pressure, be specifically related to a kind of hollow pin shaft of cubic hinge press.
Background technology
In the synthetic equipment of existing cubic hinge press, along with continuing to increase of synthetic cavity, the pressure of cubic apparatus is required also to continue to increase, this just makes that the connection bearing pin of hinge beam is more important.And existing bearing pin is too heavy, is unfavorable for the I&M of machine.
Summary of the invention
The objective of the invention is to thoroughly change the deficiency that exists in the prior art and the hollow pin shaft of cubic hinge press that a kind of volume is little, in light weight, easy for installation, be convenient to keep in repair is provided.
Technical scheme of the present invention is achieved in that and comprises hollow bearing pin and dock the following hollow bearing pin that is provided with last hollow bearing pin; It is characterized in that: be installed with mandrel between hollow bearing pin and the following hollow bearing pin on hollow; Be provided with the end plate up and down of band centre bore at the two ends of last hollow bearing pin and following hollow bearing pin, about be installed with the screw that is connected with mandrel in the centre bore of end plate.
The head of last hollow bearing pin and following hollow bearing pin be provided with diameter greater than on the step of hollow bearing pin and the diameter of following hollow bearing pin own.
The diameter of described end plate is identical with the diameter of the step of the head that is arranged on hollow bearing pin and following hollow bearing pin.
Adopt interference fits between last hollow bearing pin and following hollow bearing pin and the pin shaft hole.
The mandrel two that is put in hollow bearing pin and following hollow bearing pin hollow all is connected with end plate up and down through screw.
Advantage of the present invention is following: by the module of anti-bending section formula; Satisfying under the shear stress situation allowable of bearing pin, hollow bearing pin is more in light weight than solid pin, and whole bearing pin is divided into two hollow bearing pins; On weight, alleviate half again, this all has very big convenience to installing and keeping in repair.Both farthest reduced bearing pin weight, and reduced volume, and guaranteed the bearing pin shear resistance again, and installation, maintenance is convenient.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1; The present invention includes hollow bearing pin 1A and dock the following hollow bearing pin 1B that is provided with last hollow bearing pin 1A; It is characterized in that: be installed with mandrel 2 between hollow bearing pin 1A and the following hollow bearing pin 1B on hollow; Two hollow bearing pin 1A and 1B insert the pin shaft hole of hinge beam 5 from both direction up and down respectively, are provided with the end plate up and down 4 of being with centre bore at the two ends of last hollow bearing pin 1A and following hollow bearing pin 1B, about be installed with the screw 3 that is connected with mandrel 2 in the centre bore of end plate 4.
The head of last hollow bearing pin 1A and following hollow bearing pin 1B be provided with diameter greater than on the step 6 of hollow bearing pin 1A and the diameter of following hollow bearing pin 1B own.
The diameter of described end plate 4 is identical with the diameter of the step 6 of the head that is arranged on hollow bearing pin 1A and following hollow bearing pin 1B.
Adopt interference fits between last hollow bearing pin 1A and following hollow bearing pin 1B and the pin shaft hole.
Mandrel 2 two that are put in hollow bearing pin 1A and following hollow bearing pin 1B hollow all are connected with end plate 4 up and down through screw 3.
Concrete operation method: by the module of anti-bending section formula, satisfying under the shear stress situation allowable of bearing pin, hollow bearing pin is more in light weight than solid pin.And whole bearing pin is divided into two hollow bearing pins, on weight, alleviates half, and this all has very big convenience to installing and keeping in repair.Two hollow bearing pins insert the pin shaft hole of hinge beam from both direction up and down respectively, put into the hollow of hollow bearing pin to mandrel 2, and two ends are connected with end plate 4 with screw 3 respectively, and the assurance hollow bearing pin does not come off.Hollow bearing pin and pin shaft hole adopt interference fits.
