Description
Technical Field
The utility model relates to a spinning equipment technical field, concretely relates to heavy vertical spinning-lathe.
Background
Spinning is a special forming process, in which a circular sheet-like or hollow tubular blank is fixed on a die of a spinning machine, and is pressed on the blank by a spinning wheel or a driving rod while the blank rotates along with a main shaft of the machine, so that the blank is locally plastically deformed.
In the vertical spinning process, the spun tubular blank is placed vertically and clamped by a clamp. The circular sheet blank is horizontally placed on the main shaft die, and the circular sheet blank needs to be pressed and fixed on the main shaft die during spinning, so that the blank and the main shaft die are relatively static in the processing process, and a processed finished product is attached to the main shaft die. Meanwhile, due to general machining characteristics, the tail top is pressed to fix the blank so as to ensure that the central position of the blank does not slide under the action of machining load in the machining process and ensure the effectiveness and safety of machining.
The existing vertical spinning machine is divided into two types, namely, the processing of tubular blanks and the processing of sheet blanks. Generally, a tail top structure is not designed in a vertical spinning machine for processing tubular blanks, and due to the requirements of the processing process of the tubular blanks and the feeding and discharging process, the upper part of the processing range of a machine tool is hollowed out, so that the machine tool of the type can only process the tubular blanks and cannot process sheet blanks.
In order to ensure the convenience of processing and assembly, a tail ejection mechanism is generally fixed at the top of a machine tool and can only stretch out and draw back to eject or release a material sheet for use. This type of spinning machine is commonly used for small and medium-sized simple spinning processing, but for large and heavy vertical spinning machines, the structural problem is obvious. Because the quality of the tail top die and the material sheet is heavier than the common situation and needs to be carried out from the side of the machine tool, the use efficiency of the machine tool is greatly reduced, and the operation risk coefficient of operators is increased. If the spinning machine is used for processing pipe products, the final length of a finished product is limited due to the existence of the tail jacking mechanism, so that the application range of the machine tool is reduced. Therefore, the scheme is not suitable for the design of a large and heavy vertical spinning machine, and the processing flexibility is low.
In addition, most of the vertical spinning machines commonly used at present for processing sheet blanks are small and medium-sized machines, and for large and heavy vertical spinning machines with larger working load and more product demand range, the basic elements of the machine tools such as the structure and the power output thereof and the like can not be simply multiplied to meet the requirements of the large and heavy spinning machines. Therefore, if the actual requirements need to be met, a more reasonable mechanism and a more effective power output scheme must be adopted.
