Adjusting device and method for lever-type bottom ejector of forging press

Abstract

The present invention relates to the high-end equipment manufacturing industry, in particular to a device and method for adjusting a lever-type lower ejection material of a forging press, including a die-loading height adjustment mechanism and a lower ejection force automatic adjustment mechanism, and the die-loading height adjustment mechanism includes an elastic pre-tightening locknut, The two ends of the elastic pre-tightening anti-loosening nut are respectively designed with axial and radial opening grooves, and the locking part compresses the opening grooves to generate elastic deformation and continuous pre-tightening. The lower jacking force automatic adjustment mechanism includes a lever fulcrum seat and a guide rail to form a moving guide rail pair, the power unit drives the lever fulcrum seat to move accurately, and the locking unit locks the lever fulcrum seat. On the basis of technical characteristics such as good synchronization of lever-type mechanical lower material ejection, symmetrical balance, large ejection force (more than 3 times higher than traditional technology), green energy saving, etc., it improves efficiency and reliability and meets precision forging extrusion or multi-station There is an urgent need for automatic forging production lines and automatic control of precision die forging forming, to achieve the effect of automatic adjustment of forging presses and precise control of forging extrusion force.

Description

Technical field: [0001] The invention relates to the technical field of high-end equipment manufacturing industry, in particular to a device and method for adjusting a lever-type lower jacking force of a forging press. Background technique: [0002] The forging mechanical press generally adopts the lower jacking device. The traditional mechanical lower jacking device has a cam type and an air cushion type technical structure, but the above technical structure has technical problems such as insufficient lower jacking force, and the stroke is fixed at a certain value. Therefore, it can only meet the requirements of general forging bottom jacking, which restricts the wide application of forging mechanical presses, especially the requirements of multi-station forging and hot-touch forging presses with special large forging force. Aiming at the technical problems existing in the existing mechanical bottom jacking device, the company creatively developed a rack and pinion mechanic...

Problems solved by technology

[0003] However, in the process of practical application, it is still found that there are deep-seated technical problems that need to be further studied and solved in the technical structure, mainly in three aspects: First, the upper and lower rods are connected by adjusting nuts and lock nuts , When the mechanical press adjusts the height of the mold, it is necessary to repeatedly disassemble the lock nut and the adjustment nut used for adjustment to cause rapid wear of the thread. After a long period of use, the threaded connection becomes loose under the impact of heavy loads, resulting The problem of processing parts waste and even unable to stop normal production

The second is that the lever-type mechanical lower jacking device is set in the pit below the equipment foundation. When it is necessary to adjust the lower jacking force, it is necessary to adjust the position of the lever fulcrum seat on the lever. When adjusting, the operator needs to remove the foundation protection cover to enter Working in the pit, disassembling and adjusting the weight of the lever-type mechanical lowering device parts weighs several tons. The space in the pit is very narrow, and lifting equipment cannot be used. Moving the position requires multiple long-term debugging and repeated verifications. Therefore, it is difficult to adjust the forging force manually and the adjustment accuracy cannot be guaranteed.

The third is that with the popularization and application of automatic connection and intelligent control technology in the metal forming equipment industry, as well as the complex changes in the processing technology of special shaped precision forgings, it is indeed necessary to adjust the forging force frequently and automatically and accurately. Therefore, it is urgent to develop special technical solutions. Solve the deep-seated technical problems that the manual adjustment of the lever forging force operation of the lever-type mechanical lowering device is difficult to achieve, poor reliability, inaccuracy, low efficiency, and can not meet the needs of automation, intelligent production lines and metal forming control of special special-shaped precision forgings
