2. Most of the open press work with crank and connecting rod mechanism, and its transmission principle diagram is as follows: crank and connecting rod mechanism adapts rotary motion to reciprocating linear motion, and the reciprocating linear motion of slider gives punching pressure to the upper die to punch down the sheet metal and complete the work

the crank press transmits the motion and energy of the motor to the crankshaft through the transmission system, so that the crankshaft can rotate, and the slider can proce reciprocating motion through the connecting rod, so as to realize the motion and power requirements of stamping
the motor 1 drives the crankshaft to rotate through the belt pulley 2, the pinion 3, the big gear 4 (flywheel) and the clutch 5, and then makes the slider 7 move back and forth in the guide rail of the machine body through the connecting rod 6. The upper die of the die is fixed on the slide block 7, and the lower die is fixed on the working table of the machine body. The press can drive the upper die and the lower die to pressurize the material and make it into a workpiece by the die. The clutch 5 is controlled by the pedal through the operating mechanism, which can make the crank slider mechanism move or stop without stopping the motor
the brake works closely with the clutch to stop the slider crank mechanism at a certain position (usually at the top dead center position) after the clutch is disengaged. The big gear 4 also acts as a flywheel, so that the load of the motor is uniform and the energy is used effectively.

3. Stone, as a kind of high-grade building decoration material, is widely used in interior and exterior decoration design, curtain wall decoration and public facilities construction. At present, the common stones in the market are mainly divided into natural stone and artificial stone. According to the physical and chemical properties, natural stone can be divided into slate and granite. Artificial stone is divided into terrazzo and synthetic stone according to working procere. Terrazzo is made of cement, concrete and other raw materials; Synthetic stone is made of crushed stone of natural stone as raw material, plus adhesive, etc. by pressing and polishing. The latter two are artificial, so the strength is not as high as natural stone. Stone is a high-grade proct of building decoration materials. Natural stone is generally divided into granite, slate, sandstone, limestone, volcanic rock, etc. with the continuous development and progress of science and technology, the procts of artificial stone are constantly changing, and the quality and beauty are no less than natural stone. With the development of architectural design, stone has become one of the important raw materials for building, decoration, road and bridge construction.
