Description
Technical Field
The invention relates to a hydraulic quick forging machine, in particular to a hydraulic quick forging machine with a hammer fixedly connected to the lower end of a plunger of a hydraulic cylinder, a suspension guide beam arranged on a stand column and used for positioning and guiding the hammer, and belongs to the technical field of forging equipment design and manufacturing.
Background
The hammer head of the traditional hydraulic rapid forging machine is fixedly connected to a movable beam, and the movable beam is connected with a plunger of a downlink working hydraulic cylinder and a piston rod of an uplink return hydraulic cylinder. When the hydraulic device works, the uplink return hydraulic cylinder drives the movable beam to ascend; when the idle stroke is fast going down, the movable beam drives the hammer head to quickly approach the workpiece under the action of the oil supplementing pressure of the downlink working hydraulic cylinder and the gravity of the movable beam; during working, the hydraulic cylinder is filled with pressure oil to push the plunger and drive the hammer to roll the forging. As is evident from the above working process, during forging, the following drawbacks are highlighted because the movable beam and the hammer head must move synchronously for the fixed connection: a. the hammer head is slow due to the large weight of the moving part, so that the forging frequency is low, the linear speed of rolling is low, the application range of equipment is not wide, and the forging and pressing machine is not applicable to forging and pressing of high alloy steel; b. The flexibility is poor, and the work efficiency is low. In order to overcome the defects, a cylinder-operated hydraulic quick forging machine is designed, and the hydraulic quick forging machine is used for directly and fixedly connecting a hammer head to the lower end of a plunger of a downlink working hydraulic cylinder, so that the weight of a moving part of the quick forging machine is greatly reduced, the forging and pressing frequency of the hammer head is increased, and the sensitivity of equipment is improved. However, since the reciprocating stroke of the plunger is guided by the cylinder wall of the working cylinder, the plunger is subjected to large unbalanced load and poor guiding stability, the working stroke of the hammer is small, and the damage to equipment is large. In summary, the conventional hydraulic quick forging machine has the disadvantage that the hammer is fixed on the movable beam or directly connected to the lower end of the plunger of the downlink hydraulic cylinder, and the conventional hydraulic quick forging machine always has an unsatisfactory place.
