I. Overview:

 

1. The stretching and cold rush simulation machines are two independent devices, which are high -speed cold flushers and adjustable speed stretching machines. The special machine is dedicated to meet modern production technology and needs.

2. With the use of supporting aluminum alloy disassembly molds and transparent molds for classroom teaching stamping and stretching forming demonstration analysis function and small parts.

3. Constitution aluminum alloy parts: use hard aluminum alloy plates and oxidize treatment, hardness HB90, yield strength 245.

4. Use 0.2 ～ 0.5mm thin aluminum tablets or iron sheets and molds to produce hardware parts.

5. There is a mechanical automatic feeding system, the feeding speed is 300 times, the feeding length is 5-40cm, the adjustment is convenient and fast, and it is equipped with the Japanese OMRON infrared induction protection device.

6. The control system adopts 24V low pressure to ensure safety and reliability.

7. The column uses a hard chromium precision guide rod, and the guidance cover is carbon ink alloying cover with a self -lubricating function.

8. Use moving and fixed fixed methods.

9. Virtual simulation teaching system

 

Machinery tr--ning security education virtual simulation software: This software is developed based on UNITY3D. The software is in the form of three -dimensional roaming. It can be moved by keyboard control. The direction of the mouse control lens is equipped with mechanical safety distance experiments, mechanical safety protection device experiments, mechanical safety protection design Basic assessment and experiments, the three -dimensional roaming screen uses arrows and footprint patterns to move to the experimental location. The circle around the mechanical object shows a working radius, and the experimental process is accompanied by a three -dimensional robot dialog box reminder.

A. Mechanical safety distance experiment content includes a safe distance experiment to prevent the upper and lower limbs from touching the dangerous area (the height and opening of the two fences in the inside). After choosing to enter, the GB23821-2009 "Mechanical Security to prevent the upper and lower limbs from touching the dangerous area of the dangerous area. "Safety distance" requires that the error demonstration: After the experimental process is harmed by the working radius of the human body entering the mechanical object, the blood -colored picture and voice reminder receive mechanical damage, return to the original position and perform the next experiment. The final step is the correct practice.

B. Machinery safety protection device experiments are divided into protection device experiments such as security ch--n switches, safety curt--ns, safety cushions, safety laser scanners, etc. Optional categories (safe input, safety control, safety output, other), manufacturers, products, products, products, products, products, products, products, products, products List (safety ch--n switch, safety curt--n, safety cushion, safety laser scanner, safety controller, safety relay, safety guardr--l). The installation location has a blue flash frame reminder. The experimental process: choose a safe guardr--l and install, select a safety ch--n switch (or select a safe light curt--n, safety cushion, safety laser scanner) and install, select the safety controller and install it to the electrical control box Select the safety relay and install it to the electrical control box, click the start button on the electrical control box. If you enter the dangerous area, the system will prompt alarm and stop working. Select the reset button on the electrical control box to stop.
