Automobile lightweight aluminum alloy hot die forging press

Abstract

The invention discloses an automobile lightweight aluminum alloy hot die forging press. Comprising a machine body, a flywheel brake, a main transmission system, a planetary gear speed reducer, a crankshaft mechanism, a sliding block and connecting rod mechanism, an upper knockout mechanism, a guiding device, a mold and mold frame mechanism, a joint type mold changing device, a lower material ejecting mechanism, an intelligent mold clamping device, a cam control device, a servo type flexible stepping beam mechanism and a balancer mechanism. The invention discloses a spraying manipulator and a hot die forging anti-stuffiness vehicle hydraulic control system. Hot materials are conveyed to five stations through the flexible walking beam mechanism according to the process requirements, the processes of upsetting, pre-forging, finish forging, punching and trimming are completed through the die and die frame mechanism fixed to the lower portion of the sliding block and the upper portion of the base, the processes completed by a plurality of single machine tools are combined to one machine tool to be continuously completed, a workpiece is lubricated through the spraying mechanical arm, and the work efficiency is improved. The workpiece forming time is one thousandth of the completion time of a single machine tool, and the qualified rate of finished products is 6-7 times that of single machine tool production.

Description

technical field [0001] The invention belongs to processing equipment for automobile parts, in particular to an automobile lightweight aluminum alloy hot die forging press. Background technique [0002] Hot die forging press is a forging equipment that realizes hot forming of metal blanks by means of dies. Feeding generally adopts walking beam manipulator to improve production efficiency and feeding accuracy. It has the advantages of high material utilization rate, high production efficiency, easy to realize automation, low requirements for workers' operating technical level, low noise and vibration, etc. It is a hot die forging pressure. It is a new high-end product of the hot die forging press, and it is also the future development trend of the hot die forging press. [0003] Due to its advanced technology and complex process, the automotive lightweight aluminum alloy hot die forging press is currently only produced by Schuler in Germany. High, long cycle, affecting the n...

AI Technical Summary

Problems solved by technology

[0003] Automobile lightweight aluminum alloy hot die forging press because of its advanced technology and complicated process, currently only German Schuler produces this type of hot die forging multi-station press machine, but its product operation is complicated, the service radius is large, the maintenance cost is high, and the cycle is long, which affects the normal production

The corresponding domestic products have low degree of automation and poor stability, which cannot meet their use requirements

[0004] For the lightweight aluminum alloy hot die forging press for automobiles, Jilin General Machinery Co., Ltd. initially purchased Schuler products from Germany, but due to the high price of the products, Debugging cycle, cumbersome operation, not recognized by the operator

The main drive, clutch, and reducer are integrated, and Ortlinghaus products are used. The mold clamp uses HILMA two-way hydraulic clamps, which are expensive and have a long delivery cycle.

Not only that, other damaged parts during use still need to be purchased from the original manufacturer, resulting in inconvenient maintenance

[0005] However, for aluminum alloy forging with domestic ordinary forging machines, it takes 40 minutes at the fastest to forge a part, and the yield is lower than 20%, and the material utilization rate is lower than 30% %, multiple forging machines need to work together to basically meet the requirements

[0006] In order to improve the production efficiency of the forging machine, the applicant successively designed the articulated die changing device (CN201920001053.3), the intelligent die clamp (CN201721624664.0), Servo-type flexible walking beam mechanism (CN202021247187.2) and hot die forging hydraulic control system (CN201721624663.6), but the use of these components is only a partial improvement of ordinary forging machines, which still cannot constitute high-efficiency and high-quality Automobile lightweight aluminum alloy hot die forging equipment
