Problems solved by technology

[0002] The forging press is the basic tool for forging pressure processing. Conventional forging presses include mechanical presses, hydraulic presses and hydraulic presses. The mechanical press drives the punch through the crankshaft linkage mechanism, and the hydraulic press drives the movable beam and The punch and hydraulic press drive the movable beam and punch through hydraulic transmission to realize free forging or die forging of the forging blank. The processing capacity of the forging press is calibrated by the forging capacity. The forging force of the currently used forging press is generally 6000T ~12000T, and its high cost makes it difficult for enterprises to equip
[0003] In the currently used forging presses, the power input point of the oil (water) press is the pressure cylinder, which is used to perform work after the high-pressure medium enters the pressure cylinder, and the power to move the movable beam is also moved by the lower pressure oil. Therefore, the movable beam becomes the working part of the forging work. In order to increase productivity and increase the moving speed of the movable beam, it is necessary to set up a large-flow flushing system. Even so, the moving speed is still limited.
At present, in the oil (water) press with double-cylinder return cylinders, it is difficult to meet the synchronization requirements of the main cylinder due to the asynchronous nature of the two cylinders, especially in the case of high frequency, which will cause rapid wear of the parts and even movement. jamming phenomenon
In addition, the setting of the double cylinder can only be set at a place far away from the main cylinder. For example, the return cylinder is hung under the upper beam and connected with the movable beam. When the movable beam pushes down together with the master cylinder, the return cylinder also Simultaneous movement, when the work is completed, it is pulled back by two return cylinders, and two return cylinders must be installed, one on the left and the other on the right of the movable beam, making the structure very complicated
Moreover, for the currently used forging press, such as fast forging, the traditional operation is to use the frequent reciprocating operation of the main cylinder and the return cylinder, which causes great vibration of the press, which is not conducive to the forging of the blank.

Embodiment 1

[0039] Example 1 as figure 1 and image 3 As shown, the forging press of the present invention includes an upper beam 2, a lower beam 18 and at least one column 1. Of course, a plurality of columns 1 are generally used to play a fixing role. In this embodiment, two columns 1 are used, and the column 1 The lower end of the lower beam is fixed on the lower beam 18, the upper beam 2 is arranged on the upper end of the column 1 to form a frame, and the upper beam 2, the lower beam 18 and a column 1 are fixedly connected to form a frame by prestressed bolts 3, and adopt Hydraulic tensioner is used to complete the preload. The frame preloaded by this method has very good rigidity, and even reaches the requirement of infinite rigidity. Only when this requirement is met can it withstand the shock and vibration during forging. The frame material structure can be greatly strengthened selectively, and casting parts or structural parts can be used. This kind of prestressed structure fram...

Abstract

A forging apparatus comprises an upper beam (2), a lower beam (18) and at least one column (1). The lower end of the column (1) is fixed on the lower beam (18), the upper beam (2) is disposed at the upper end of the column (1), a movable beam driving apparatus is disposed on the upper beam (2), and the movable beam driving apparatus is connected through a spiral mechanism to a main hydraulic cylinder (16) and a return cylinder (14) capable of cushioning. The forging apparatus may connect the spiral mechanism in the driving apparatus, the main hydraulic cylinder (16) and the return cylinder (14) together without being provided with the movable beam. The forging apparatus is characterized in that the structure is simple, and the operation is convenient and fast; the structural strength is high, the vibration is small, the anti-unbalanced loading capability is strong, the manufacturing, assembly and repair are convenient, and the cost is low.
