Abstract

The invention relates to a ram type connecting-rod-free high-rigidity novel press machine. The press machine comprises a sliding block body, a screw rod, a machine body, a crankshaft, a ram, a sleeve rod, a connecting rod, a pressing plate and a turbine; the sliding block body, the screw rod, the crankshaft, the ram, the sleeve rod, the connecting rod, the pressing plate and the turbine are respectively arranged in the machine body; the crankshaft rotates in the machine body, the crankshaft is connected with the ram, the ram is arranged in the loop bar, and the crankshaft which rotates drives the ram to slide back and forth in the loop bar; the sleeve rod is connected with the connecting rod through a pin shaft, the connecting rod is connected with the screw rod, and the sleeve rod and the connecting rod swing back and forth and push the screw rod; the screw rod is connected with the turbine through threads, and the turbine pushes the sliding block to move up and down in a reciprocating mode. A traditional connecting rod and ball head screw structure is abandoned, so that the machine tool is good in rigidity, due to the fact that the connecting rod and ball head screw structure is omitted, the machine body height direction is greatly shortened, the machine tool rigidity is further improved, the stamping part forming effect is good, and the service life of the die is long.

Description

Technical Field

[0001] The invention relates to a press, in particular to a ram-type connecting rod-free high-rigidity new press. Background Art

[0002] For a long time, presses generally use connecting rods to connect the crankshaft and the slider. The closing height can be adjusted, and it has strong adaptability to different processing needs. The existing problems are: the rigidity of the equipment is poor, the accumulated error is large, and the accuracy is affected during use. With the advent of the era of processing specialization, the equipment used in many occasions requires high precision and good rigidity, but not high adaptability. Summary of the invention

[0003] The object of the present invention is to provide a new type of high rigidity press machine with a ram type and no connecting rod, which has a compact structure, is easy to process and can improve the overall precision and rigidity of the machine tool.

[0004] The technical solution of the present invention is: a new type of ram-type connecting rod-free high-rigidity press, characterized in that: the press comprises a slider body, a screw rod, a body, a crankshaft, a ram, a sleeve rod, a connecting rod, a pressure plate and a turbine; The slider body, screw rod, crankshaft, ram, sleeve rod, connecting rod, pressure plate and turbine are respectively arranged in the body; The crankshaft rotates in the machine body, the crankshaft is connected to the ram, the ram is arranged in the sleeve rod, and the rotating crankshaft drives the ram to slide back and forth in the sleeve rod; The sleeve rod is connected to the connecting rod through a pin, the connecting rod is connected to the screw rod, and the sleeve rod and the connecting rod swing back and forth and push the screw rod; The screw rod is connected to the turbine through a thread, and the turbine drives the slider to reciprocate up and down.

[0005] The beneficial effects of the present invention are: the traditional connecting rod and ball screw structure are abandoned, so that the machine tool has good rigidity. Since the connecting rod and ball screw structure are cancelled, the height direction of the machine body is greatly shortened, thereby further increasing the rigidity of the machine tool, the stamping part forming effect is good, and the mold service life is long.
