Embodiment Construction

[0015] Such as Figure 1-2 As shown, a technical solution adopted in a specific embodiment is introduced: including a lower guide sleeve 6, an upper mold 2, an upper guide sleeve 3, a column 4, two groups of grating rulers 5 and three force sensors 1, and three force sensors 1 are installed Between the upper mold 2 and the upper guide sleeve 3, it is used to detect the pressure of the servo press; a set of grating scales 5 is arranged between the column 4 and the upper guide sleeve 3, and another set of grating scales is arranged between the column 4 and the lower guide sleeve 6. Group grating ruler 5. When in use, the numerical control system sends a control signal to the servo driver, so that the output shaft of the servo motor is controlled to rotate through the servo driver (the rotation amount is fed back to the servo driver and the numerical control system through the encoder), after that, the output shaft of the servo motor will directly drive The ball screw rotates to...

Abstract

The invention relates to a force position control system for a hard alloy tool precision servo press machine, and belongs to the field of powder metallurgy. Force sensors, an upper die, an upper guiding sleeve, stand columns, grating rulers and a lower guiding sleeve are included. The three force sensors are evenly distributed along the circumference, arranged between the upper die and the upper guiding sleeve and used for detecting the pressure of the servo press machine. One grating ruler is arranged between the stand columns and the upper guiding sleeve, the other grating ruler is arrangedbetween the stand columns and the lower guiding sleeve, and the two grating rulers are matched and used for detecting the actual displacement of the upper die and a lower die. Signals of all the forcesensors and the grating rulers are finally input into a numerical control system. By means of the force position control system, the manufacturing precision of a precision hard alloy tool product canbe accurately controlled, reliability is good, stability is high, and obvious advantages are achieved in the powder metallurgy industry.

Description

technical field [0001] The invention relates to the field of powder metallurgy, in particular to a force-position control system for a precision servo press for hard alloy cutters. Background technique [0002] Nowadays, with the rapid development of metal cutting, the use of precision carbide tools is increasing, and the production efficiency and cost requirements for precision carbide tools are also increasing. At present, precision carbide tools are manufactured by powder metallurgy molding, while finished tools still need to be manufactured by precision machining such as grinding. To improve the efficiency of precision machining such as grinding, it is necessary to ensure that the margin of the tool blank is small enough within a certain range, so the tool is required to have good precision stability in the mass production process of powder metallurgy forming. [0003] In addition, due to the characteristics of the powder metallurgy process, after the parts are pressed ...
