Intelligent control method for die hammer and intelligent die hammer produced according to said method

Abstract

Disclosed are an intelligent control method for a die hammer and an intelligent die hammer produced according to said method. The method comprises the following steps: (1) initialization: controlling oil temperature, pressure, cleaning degree and die equipment temperature, and determining the striking energy, times, order and frequency frequency according to the material quality, size and deformation degree of the forgeable pieces; (2) striking: heating the forgeable piece until it reaches the temperature for forging, moving the workpiece to a model chamber chamber for striking through a manipulation mechanical arm, after that, transferring the forgeable piece to a final product box through the manipulation mechanical arm; (3) intelligence controlling: detecting on-line the forgeable piece thickness, machine frame vibration movement and forgeable piece temperature parameters, and automatically optimizing the striking parameters. For the die hammer which is equipped with a behavior monitoring apparatus comprising a sensor mounted at the die hammer, wherein the sensor is connected to the behavior monitoring apparatus, the monitoring apparatus includes an expert system, a hydraulic-oil executive supervisor, a temperature executive supervisor , a forgeable piece size monitoring system, an intelligence control system and the like, and a mechanical arm. The invention has the following beneficial effect: it can realize automatization and intelligentization of a hammer and the parameter optimization control, avoid man's activity. One can select optimal the starting and final forging temperature and the striking energy, time, order and frequency, according to the forgeable piece material and the deformation degree. The striking energy, forgeable piece striking direction and size and the forgeable piece temperature are detected, and then corrected to realize the high automatization and the optimized control.

Description

Technical field: [0001] The invention relates to die forging equipment in metal forming equipment, which is a highly automated die forging hammer, in particular, an intelligent control method for the die forging hammer and the intelligent die forging hammer produced according to the method. Background technique: [0002] There are following deficiencies in existing die forging hammer: [0003] 1. The working temperature of the mold is not automatically controlled, which affects the service life of the mold and the quality of forgings. [0004] 2. Loading, die chamber change, and blanking are all manual operations, and the operating time varies from person to person. It is difficult to control the initial forging and final forging temperatures, which reduces the quality of forgings. At the same time, the working environment is harsh and labor-intensive. [0005] 3. The strike energy, frequency and sequence are manually adjusted, and the level of the operator affects the qual...

Problems solved by technology

[0003] 1. The working temperature of the mold is not automatically controlled, which affects the service life of the mold and the quality of forgings

[0004] 2. Loading, die chamber change, and blanking are all manual operations, and the operating time varies from person to person. It is difficult to control the initial forging and final forging temperatures, which reduces the quality of forgings. At the same time, the working environment is harsh and labor-intensive

[0005] 3. Manual adjustment of strike energy, frequency and order, the level of the operator affects the quality of the forging, it is difficult to optimize the strike parameters, and the excess strike energy causes strong vibration and high failure rate

[0006] 4. The size and thickness of the forging in the strike direction will not be detected online

[0007] 5. There is no return buffer device, and the hammer rod of the forging hammer is prone to failure
