specific Embodiment approach 2

[0009] Specific implementation mode two: combination figure 2 To illustrate this embodiment, two longitudinal weight-reducing through holes 12 are provided on the upper end surface of the slider 8 of this embodiment at positions symmetrical to the central axis. With this setting, good acceleration performance can be obtained. Under the same force, the lighter the moving part, the better. Other components and connections are the same as those in the first embodiment.

[0010] The working process of the system of the present invention is: in order to ensure the synchronization of the motion of the two linear motors, the two linear motors are controlled by a set of controllers. According to the specific forming process, the motion trajectory of the linear motor is formulated, that is, the output displacement-time curve of the linear motor, and the linear motor controller controls the motion of the linear motor according to the motion trajectory. At the beginning of the movemen...

The two frames (2) are fixedly connected to the left and right ends of the base (1), the two brackets (3) are fixedly connected to the two frames (2), and the slider (8) is installed between the two brackets (3). Between, the front and rear ends of the slider (8) are symmetrically provided with a linear motor (4), the primary (14) of the linear motor (4) is fixedly connected with the support (3), and the secondary (13) of the linear motor (4) Fixedly connected with the slide block (8), four guide rails (5) are fixedly installed on the slide block (8), and the guide rail (5) slides and cooperates with the guide rail chute (11) of the guide rail slider (6), and the guide rail slide block (6 ) is fixedly connected with the bracket (3), the air brake (7) fixedly connected with the bracket (3) is arranged directly above the four guide rails (5), the grating scale (9) is fixedly mounted on the slide block (8), and the grating scale The probe (10) is set close to the grating ruler (9) and fixed on the frame (2). The invention can realize low-cost, large-volume microplastic parts forming.

Description

technical field [0001] The invention relates to a driving device for high-speed and high-precision micro-stamping forming of micro parts. Background technique [0002] The geometric size of the parts in microplastic forming is very small, which puts forward high requirements on the movement speed, positioning accuracy and forming efficiency of the forming equipment, and requires the equipment to be able to achieve precise control of displacement and forming force. The driving device of traditional forming equipment can no longer meet the needs of microplastic forming. For example, the crank drive equipment cannot automatically control the pressure due to its fixed displacement-time characteristic; although the hydraulic and pneumatic drive equipment can meet these requirements, they cannot achieve fast stamping frequency; although the piezoelectric drive forming system has a fast response speed, The output force and working stroke can also be adjusted, but the output displa...
