Description
Technical field
The present invention relates to heavy technical field of forging, in particular to a kind of large-scale combined hydraulic press is with can constantly pre-tighten
Frame structure.
Background technique
Heavy type forging field now, hydraulic forging press are mostly prestressing combination frame structure, this frame bears whole
Nominal load.In previous press, turnbuckle is pre- next without any detection method and reply device.In forging process,
Press frame bears frequent vertical direction load, and turnbuckle, which easily occurs to loosen, causes prestressed frame to fail, and especially exists
It is particularly evident in the press of Duola's rod structure.To solve the above-mentioned problems, special to have developed a kind of band and constantly pre-tighten the new-type of function
Frame structure.
Summary of the invention
The present invention in view of the above technical problems, proposes a kind of large-scale combined hydraulic press frame knot that can constantly pre-tighten
Structure.
To achieve the above objectives, it is achieved through the following technical solutions:
A kind of large-scale combined hydraulic press frame structure that can constantly pre-tighten, comprising: turnbuckle, frame, stress
Test device, automatic pre-tightening apparatus, top nut and lower nut；
Frame is the rectangular frame structure being made of top load-carrying members, medial support structures and bottom load-carrying members, and
Inside has the perforative rectangular operation cavity in opposite flank；
Wherein, top load-carrying members, medial support structures and bottom load-carrying members are preset with installation position through-hole, and top is held
Run through in the assembly through-hole that weight structure, medial support structures and bottom load-carrying members are formed after aligning up and down and be packed into turnbuckle,
And turnbuckle upper end stretches out in top load-carrying members part and is equipped with top nut, turnbuckle upper end stretches out in bottom load-bearing knot
Structure part is equipped with lower nut；
Wherein, the automatic pre-tightening apparatus for driving top nut to rotate is each equipped in each top nut；
Stress test device quantity is identical as turnbuckle quantity, and each turnbuckle is inserted into medial support structures
Part body of rod surface is each equipped with a stress test device, and the connection of this stress test device and current turnbuckle top
The automatic pre-tightening apparatus in portion connects.
The present invention by adopting the above technical scheme, the automatic pre-tightening apparatus dress of the hydraulic pre-tightening mechanism composition of translator adjustment
It is connect on the head of turnbuckle, and with top nut；Stress detection device is mounted on the surface of every turnbuckle.
When press is pre- next, the stress of every turnbuckle is a definite value；Stress mornitoring positioned at turnbuckle surface fills
It sets and answers force feedback in automatic pre-tightening apparatus turnbuckle；When press work under upper and lower impact loading a period of time,
Top nut, lower nut and turnbuckle relatively rotate, and the prestressing force of turnbuckle changes；Stress detection device is constantly
Ground is by the stress value feedback of turnbuckle in automatic pre-tightening apparatus, and after this value of feedback is less than setting value, automatic pre-tightening apparatus is certainly
It starts building to make, turnbuckle is stretched, is pre-tightened to setting value.The preload value of automatic pre- next all turnbuckles of press is suitable, pressure
The pretightning force of machine each column is in uniform state, and press will not be overhauled because of prestressed failure, overhaul, saves user
Working service cost, improve equipment level and the automation of press.
The above description is only an overview of the technical scheme of the present invention, in order to better understand the technical means of the present invention,
And it can be implemented in accordance with the contents of the specification, and in order to allow above and other objects, features and advantages of the invention can
It is clearer and more comprehensible, it is special below to lift preferred embodiment, and cooperate attached drawing, detailed description are as follows.
Detailed description of the invention
The present invention totally 1 width attached drawing, wherein:
Fig. 1 is overall structure diagram of the invention.
In figure: 1, turnbuckle, 2, frame, 3, connection, 4, stress test device, 5, automatic pre-tightening apparatus, 6, upper spiral shell
Mother, 7, lower nut.
Specific embodiment
A kind of large-scale combined hydraulic press frame structure that can constantly pre-tighten as shown in Figure 1, comprising: turnbuckle
1, frame 2, stress test device 4, automatic pre-tightening apparatus 5, top nut 6 and lower nut 7；
Frame 2 is the rectangular frame structure being made of top load-carrying members, medial support structures and bottom load-carrying members, and
Inside has the perforative rectangular operation cavity in opposite flank；
Wherein, top load-carrying members, medial support structures and bottom load-carrying members are preset with installation position through-hole, and top is held
Run through in the assembly through-hole that weight structure, medial support structures and bottom load-carrying members are formed after aligning up and down and be packed into turnbuckle 1,
And 1 upper end of turnbuckle stretches out in top load-carrying members part and is equipped with top nut 6,1 upper end of turnbuckle stretches out in bottom and holds
Weight structure part is equipped with lower nut 7；
Wherein, the automatic pre-tightening apparatus 5 for driving top nut 6 to rotate is each equipped in each top nut 6；
4 quantity of stress test device is identical as 1 quantity of turnbuckle, and each turnbuckle 1 is inserted into intermediate supports
Structure division body of rod surface is each equipped with a stress test device 4, and the connection 3 of this stress test device 4 and current drawing
The automatic pre-tightening apparatus 5 at tight 1 top of bolt connects.
The present invention by adopting the above technical scheme, the automatic pre-tightening apparatus dress of the hydraulic pre-tightening mechanism composition of translator adjustment
It is connect on the head of turnbuckle 1, and with top nut 6；Stress detection device 4 is mounted on the surface of every turnbuckle 1.
