Example Embodiment

[0016] Example

[0017] The two-stage extrusion device of this embodiment, such as figure 1 with figure 2 As shown, a boosting mechanism 1 and a force applying mechanism 2 are included.

[0018] Such as image 3 with Figure 4 As shown, the booster mechanism 1 includes a base 11 and a platen 12, and a push rod 17, which are arranged oppositely, and the base 11 is fixed on the frame. The push rod 17 may be a push rod of the oil cylinder 3 or a push rod of a stepping motor, or a push rod of a power mechanism.

[0019] The machine base 11 is fixed on the frame, and a semi-cylindrical push block 13 and at least two sets of connecting rods 14 are respectively arranged at two opposite sides of the semi-cylindrical push block between the machine base 11 and the table 12.

[0020] The semi-cylindrical push block 13 is fixed on the push rod and can reciprocate between the machine base 11 and the table 12, and the semi-cylindrical push block 13 is formed with an arc-shaped sliding groove 13-1...

Abstract

The invention relates to a two-stage extrusion device, and belongs to the technical field of press operation. The two-stage extrusion device comprises a power-assisted mechanism and a force applying mechanism; the power-assisted mechanism comprises a push rod, a machine base, a table plate, a semi-cylindrical pushing block and connecting rod sets; an arc-shaped sliding groove which extends in thecircumferential direction of the central line of the semi-cylindrical pushing block is formed in the semi-cylindrical pushing block; each connecting rod set comprises upper connecting rods, lower connecting rods, a pull-back rod and a pin shaft; sliding blocks are arranged between one ends of the semi-cylindrical pushing block and one ends of the lower connecting rods; the force applying mechanismcomprises left connecting rods, right connecting rods, a top block and a connecting shaft; one ends of the left connecting rods and one ends of the right connecting rods are jointly hinged to the same connecting shaft; the other ends of one of the left connecting rods and the right connecting rods are hinged to a machine frame; and the other ends of two of the left connecting rods and the right connecting rods are hinged to a template. The two-stage extrusion device has the advantages that the structure is simple, a novel transmission mode can be achieved, the transmission capacity can be improved by more than multiple times, the energy consumption can be effectively reduced, the structure is compact, the size is small, and impact vibration and impact noise can be reduced.

Description

technical field [0001] The invention relates to a two-stage extrusion device, which belongs to the technical field of press operation. Background technique [0002] The devices currently used in the market for stamping, stretching and extrusion production, such as those used in hydraulic sheet blanking machines, are mechanical blanking machines driven by motors that drive pulleys, pulleys that drive gears to rotate, and gears that drive crank mechanisms. When it is working, not only the impact vibration and impact noise are large, but also the power consumption is high. [0003] The patent number applied by the inventor is ZL201120326594.7, and the name of the invention is a Chinese patent of a hydraulic sheet blanking machine. The lower end of the toggle lever is hinged at the corner of the toggle lever, and the lower end of the toggle lever is hinged on the flat lower support on the machine base plate. One end of the short connecting rod of the toggle booster mechanism is...
