Description
Technical Field
The invention belongs to the technical field of cold extrusion forging and pressing machinery, and particularly relates to a machine body structure applied to a large-tonnage horizontal unilateral load of a multidirectional die forging press.
Background
The prior art is as follows:
the multiple die forging press is widely applied to the multiple-pass forging production. The left and right side extrusion cylinders of a common 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 vertical column of the equipment cannot bear the lateral load.
However, the present inventors have found that the above prior art has at least the following technical problems:
when the reducing multi-pass body needs to be forged, different loads can be generated by the horizontal cylinders on the two sides due to the difference of the sizes of punched holes of workpieces, and even a single-side load can be generated under certain processes. On a small-tonnage press, partial unbalance loading is generally counteracted by increasing the positioning pin below the die in a large mode, but when the tonnage is too large, the unbalance loading is not counteracted by infinitely increasing the positioning pin.
The difficulty and significance for solving the technical problems are as follows:
therefore, based on the problems, the fuselage structure applied to the large-tonnage horizontal unilateral load of the multi-direction die forging press, which can offset the damage of the offset load force to the fuselage, has important practical significance.

The embodiment of the application can also adopt the following technical scheme:
in the machine body structure applied to the large-tonnage horizontal unilateral load of the multidirectional die forging press, the support column A is welded and fixed with the horizontal cross beam A, and a gap of 0.5-1 mm is reserved between the support column A and the vertical stand column A.
In the machine body structure applied to the large-tonnage horizontal unilateral load of the multidirectional die forging press, the support column B is welded and fixed with the horizontal cross beam B, and a gap of 0.5-1 mm is reserved between the support column B and the vertical stand column B.

Drawings
Technical solutions of 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 illustrative purposes only and thus do not limit the scope of the present application. Furthermore, unless otherwise indicated, the drawings are intended to be illustrative of 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 frame column A; 3. a vertical frame column B; 4. a mode locking beam; 5. a horizontal beam A; 6. a horizontal beam B; 7. a support pillar 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 the small-tonnage is in unbalance loading, a mold locking beam in contact with a vertical stand column is not needed, but a positioning key is additionally arranged below a mold and a workbench to resist the small-tonnage unbalance loading, and the positioning key can only bear relatively small load difference under the condition and cannot be applied to the condition of large-tonnage unilateral loading.
The embodiment is suitable for the condition that the horizontal extrusion cylinders on two sides of the multidirectional die forging press do not participate in working at the same time or the loads on two sides have large tonnage difference. And a support column A and a support column B are added between the horizontal beam of the horizontal rack and the upright post of each vertical rack. The outer side of the supporting column is firmly welded with a horizontal cross beam of the horizontal rack, and a gap of 0.5-1 mm is reserved between the inner side of the supporting column and an upright column of the vertical rack and used for deformation compensation. The die of the workpiece is contacted with the inner side of the upright post of the vertical frame through the upper die locking beam and the lower die locking beam to form a closed stress body. Thus, the horizontal frame, the supporting columns, the vertical frame and the mould can jointly participate in the counteracting work of the horizontal single-side load.
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Example 1
The mould 1 is added with a mould locking beam 4 which can be contacted with the inner sides of a vertical frame upright A2 and a vertical frame upright B3. Support columns A and B8 are additionally arranged among the horizontal beam A5, the horizontal beam B6 and the vertical rack upright post A2 and the vertical rack upright post 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, the force is transmitted to the right vertical frame upright B3 through the die 1 and the die locking beam 4, the vertical frame upright B3 generates a force bending from the inner side to the outer side, and the force enables the gap between B3 and B8 to be closed (on the contrary, the gap between A2 and A7 can be increased), so that the bending amount of B3 is limited, and the damage of excessive bending to the vertical fuselage is avoided. Meanwhile, the reaction force generated by the horizontal squeezing cylinder a9 itself is transmitted to the horizontal cross member B6 on the right side through the integral horizontal frame. Since the present embodiment is provided with the support column B8, the horizontal 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 unbalance loading. Under the condition that the horizontal extrusion cylinder works on one side, A2 and A7, B3 and B8 are always in a state that one side is closed and the other side is opened, 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:
this embodiment just can not produce the unbalance loading through two sets of strength mutual balance, has played the guard action to equipment.
In conclusion, the invention provides the machine body structure which can offset the damage of the offset load force to the machine body and is applied to the large-tonnage horizontal unilateral load of the multidirectional die forging press.
The present invention has been described in detail with reference to the above examples, but the description is only for the preferred examples of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
