Description
Technical Field
The invention belongs to the technical field of cold extrusion forging machinery, and particularly relates to a fuselage structure applied to a large-tonnage horizontal single-side load of a multidirectional die forging press.
Background
The prior art comprises the following steps:
the multiple die forging press is widely applied to the multi-body forging production. The left and right side extrusion cylinders of the general multidirectional die forging press have the same tonnage and apply the same force during forging, so that the forces on the two horizontal sides of the frame can be mutually offset, and the equipment upright post can not bear side load.
However, the inventor of the present application found that at least the following technical problems exist in the above prior art:
when the multi-pass body with different diameters is required to be forged, different loads can be generated by the horizontal cylinders on two sides due to the difference of punching sizes of the workpieces, and even single-side loads can be generated under certain processes. On a small tonnage press, partial unbalanced load is generally counteracted by adding a large positioning pin below a die, but when the tonnage is too large, the positioning pin is infinitely increased to counteract the unbalanced load.
Difficulty and meaning for solving the technical problems:
therefore, based on the problems, the fuselage structure which can offset the damage of the fuselage caused by the unbalanced load and is applied to the large-tonnage horizontal single-side load of the multi-directional die forging press is of great practical significance.

1. the invention solves the problem of large tonnage unbalanced load by mutual transmission of forces, plays a role in protecting the machine, and solves the unbalanced load problem caused by unequal left and right horizontal cylinder loading in multi-directional die forging.
Drawings
The technical solutions of the embodiments of the present application will be described in further detail below with reference to the accompanying drawings, but it should be understood that these drawings are designed for the purpose of illustration only and thus are not limiting of the scope of the present application. Moreover, unless specifically indicated otherwise, the drawings are intended to conceptually illustrate the structural configurations described herein and are not necessarily drawn to scale.
Fig. 1 is a schematic structural diagram of a first embodiment of the present invention.
In the figure:
1. a mold; 2. a vertical stand column A of the vertical frame; 3. a vertical frame upright B; 4. a mode locking beam; 5. a horizontal cross beam A; 6. a horizontal cross beam B; 7. a support column A; 8. a support column B; 9. a horizontal extrusion cylinder A; 10. and a horizontal extrusion cylinder B.
Detailed Description
In the past, when small tonnage unbalanced load, the mode locking beam contacted with the upright post of the vertical frame is not needed, and the small tonnage unbalanced load is resisted by additionally arranging a positioning key below the die and on the workbench, so that the positioning key can only bear relatively small load difference and cannot be applied to the condition of large tonnage single side load.
The embodiment is suitable for the situations that horizontal extrusion cylinders at two sides of the multidirectional die forging press do not participate in work at the same time or the load at two sides has large tonnage difference. Support columns A and B are added between the horizontal beam of the horizontal frame and the upright post of each vertical frame. The outer side of the support column is firmly welded with the horizontal cross beam of the horizontal frame, and a gap of 0.5-1 mm is reserved between the inner side of the support column and the upright post of the vertical frame for deformation compensation. The die of the workpiece contacts the inner sides of the upright posts of the vertical frame through the upper and lower die locking beams to form a closed stress body. Thus, the horizontal rack, the support column, the vertical rack and the die can participate in the offset work of the horizontal unilateral load.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
Example 1
The mold 1 is added with a mold locking beam 4 which can be contacted with the inner side of the vertical frame upright post A2 and the inner side of the vertical frame upright post B3. The horizontal beam A5, the horizontal beam B6 and the vertical frame upright post A2 are added with the support column A and the support column B8 between the vertical frame upright posts B3.
The working process comprises the following steps: when the left horizontal extrusion cylinder A9 applies load and the right horizontal extrusion cylinder B10 does not apply load, the workpiece in the die is subjected to the force of the left horizontal extrusion cylinder A9, and the force is transmitted to the right vertical frame upright B3 through the die 1 and the mode locking beam 4, so that the vertical frame upright B3 generates force bending from the inner side to the outer side, and a gap between the B3 and the B8 is closed (the gap between the A2 and the A7 is increased in contrast), thereby limiting the bending amount of the B3 and avoiding damage to the vertical machine body due to excessive bending. At the same time, the reaction force generated by the horizontal extrusion cylinder A9 is transmitted to the horizontal cross beam B6 on the right side through the integral horizontal frame. Since the support column B8 is provided in this embodiment, the horizontal cross beam B6 applies an equal force from the outside to the inside of the vertical frame column B3 through the support column B8 to offset the unbalanced load. Under the condition that the horizontal extrusion cylinder works on one side, A2, A7, B3 and B8 are always in a state that one side is closed and the other side is slotted, so that the inner side of the support column cannot be welded with the upright post of the vertical frame.
The technical scheme in the embodiment of the application at least has the following technical effects or advantages:
in the embodiment, through the mutual balance of the two groups of forces, unbalanced load can not be generated, and the protection effect on equipment is achieved.
In summary, the invention provides a fuselage structure which can counteract the damage of unbalanced load force to the fuselage and is applied to large-tonnage horizontal single-side load of a multidirectional die forging press.
The foregoing examples illustrate the invention in detail, but are merely preferred embodiments of the invention and are not to be construed as limiting the scope of the invention. All equivalent changes and modifications within the scope of the present invention are intended to be covered by the present invention.
