Abstract
The invention discloses a kind of hydraulic press buffer fixed base set bolt pulling force cancellation element, buffer fixed base one longitudinal side wall and hydraulic press stationary plane longitudinal side wall are fitted, the two is fixedly connected with in the longitudinal side wall that some set bolts are arranged in buffer fixed base and hydraulic press stationary plane, described buffer fixed base is provided with the fixed base plate of level, this fixed base plate is tight against hydraulic press stationary plane lower horizontal wall, be provided with connector, the two is connected with in hydraulic press stationary plane lower horizontal wall by the fixed base plate that described connector is vertically closely inserted in buffer fixed base, the present invention is carried by connector and mating surface, set bolt is only used as to compress buffer fixed base, not by oblique pulling force, thus eliminating the break hidden danger, when connector and stationary plane contact area strengthen, be equivalent to the lifting surface area adding pulling force, also just achieve and increase loaded ability, save process time and manufacturing cost.<!--1-->
Description
Technical field
The present invention relates to a kind of hydraulic press buffer fixed base fixed structure, particularly a kind of hydraulic press buffer fixed base set bolt pulling force cancellation element.
Background technology
Current buffer fixed base is connected to hydraulic press stationary plane longitudinal side wall by the bolt of some levels, and when holder is subject to power upwards, shearing is carried by the stressed side of shearing, set bolt under tension.When this pulling force exceedes bolt utmost carrying ability, bolt can rupture from bottom to top successively, danger buffer fixed base being had drop.
Summary of the invention
In order to make up above deficiency, the invention provides a kind of hydraulic press buffer fixed base set bolt pulling force cancellation element, this hydraulic press buffer fixed base set bolt pulling force cancellation element avoids bolt to be subject to oblique pulling force, and reducing buffer fixed base has the possibility dropped.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of hydraulic press buffer fixed base set bolt pulling force cancellation element, buffer fixed base one longitudinal side wall and hydraulic press stationary plane longitudinal side wall are fitted, the two is fixedly connected with in the longitudinal side wall that some set bolts are arranged in buffer fixed base and hydraulic press stationary plane, described buffer fixed base is provided with the fixed base plate of level, this fixed base plate is tight against hydraulic press stationary plane lower horizontal wall, be provided with connector, the two is connected with in hydraulic press stationary plane lower horizontal wall by the fixed base plate that described connector is vertically closely inserted in buffer fixed base.
As a further improvement on the present invention, described connector is key, the keyway that fixed base plate is corresponding with difference setting position on the side that hydraulic press stationary plane lower horizontal wall contacts with each other and size, and key is closely inserted in keyway.
As a further improvement on the present invention, described key is flat key.
As a further improvement on the present invention, described hydraulic press stationary plane lower horizontal wall is provided with inner groovy, and the fixed base plate of buffer fixed base is provided with projection corresponding with it, and described projection is closely inserted in the inner groovy of hydraulic press stationary plane lower horizontal wall.
Advantageous Effects of the present invention is: the present invention is by extending back holder base plate, and increase connector, wherein flat key is good, connector is stuck between stationary plane and buffer fixed base base plate, because gap between connector and stationary plane is less than the gap of set bolt and bolt hole, therefore, when pulling force produces, first carried by connector and mating surface, set bolt is only used as to compress buffer fixed base, not by oblique pulling force, thus eliminating the break hidden danger, this structure, when connector and stationary plane contact area strengthen, be equivalent to the lifting surface area adding pulling force, also just achieve and increase loaded ability, relative to the original mode to increase set bolt quantity to reach increase load capacity, save process time and manufacturing cost.

Detailed description of the invention
Embodiment: a kind of hydraulic press buffer fixed base set bolt pulling force cancellation element, buffer fixed base 1 one longitudinal side wall and hydraulic press stationary plane 2 longitudinal side wall are fitted, the two is fixedly connected with in the longitudinal side wall that some set bolts 3 are arranged in buffer fixed base 1 and hydraulic press stationary plane 2, described buffer fixed base 1 is provided with the fixed base plate 4 of level, this fixed base plate 4 is tight against hydraulic press stationary plane 2 lower horizontal wall, be provided with connector, the two is connected with in hydraulic press stationary plane 2 lower horizontal wall by the fixed base plate 4 that described connector is vertically closely inserted in buffer fixed base 1, due between connector and stationary plane for closely cooperating, its gap is less than the gap of set bolt and bolt hole, therefore, when pulling force produces, first carried by connector and mating surface, set bolt is only used as to compress buffer fixed base 1, not by oblique pulling force, thus eliminating the break hidden danger, this structure, when connector and stationary plane contact area strengthen, be equivalent to the lifting surface area adding pulling force, also just achieve and increase loaded ability.Relative to the original mode to increase set bolt quantity to reach increase load capacity, save process time and manufacturing cost.
Described connector is key 5, the keyway that fixed base plate 4 is corresponding with difference setting position on the side that hydraulic press stationary plane lower horizontal wall contacts with each other and size, key 5 is closely inserted in keyway, when pulling force produces, first carried by key 5 and mating surface, added the lifting surface area of pulling force by lengthening key 5 and stationary plane, realize increasing loaded ability.
Described key 5 is flat key.
Described hydraulic press stationary plane lower horizontal wall is provided with inner groovy, and the fixed base plate of buffer fixed base 1 is provided with projection corresponding with it, and described projection is closely inserted in the inner groovy of hydraulic press stationary plane lower horizontal wall.
