Embodiment Construction

[0017] The preferred embodiment of the multi-groove static pressure guide rail of the present invention is shown in Figure 3, comprising a master cylinder, a plunger is arranged in the master cylinder, the outer wall of the plunger is a smooth outer wall, and the main cylinder The inner wall of the cylinder is longitudinally provided with a plurality of diversion grooves.

[0018] The depth of the diversion groove is 1-2 times of the gap between the master cylinder and the plunger, and the plurality of diversion grooves are continuously covered with the inner wall of the master cylinder.

[0019] The cross section of the diversion groove is triangular, and may also be other shapes.

[0020] Such as Figure 5 As shown, there is an annular high-pressure groove in the middle of the inner wall of the master cylinder, and the inner walls of the master cylinder on both sides of the high-pressure groove are respectively covered with diversion grooves, and the two ends of the master ...

Abstract

The invention discloses a multi-groove type hydrostatic guideway and a fine punching pressure machine. The multi-groove type hydrostatic guideway comprises a main cylinder and a plunger, wherein the plunger is provided with a smooth outer wall; the inner wall of the main cylinder is longitudinally provided with a plurality of flow guide grooves; and hydraulic oil can generate eddy resistance when passing through the edges of the flow guide grooves every time. The multi-groove type hydrostatic guideway has the advantages of large damping force, high reliability, high carrying capacity, easy processing, low cost, and the like and is particularly suitable for a large-tonnage fine punching pressure machine.

Description

technical field [0001] The invention relates to a static pressure guide rail suitable for a large-tonnage fine blanking press, in particular to a multi-groove static pressure guide rail and a fine blanking press. Background technique [0002] The guide rail structure is the core technology of the fine blanking press, which directly affects its guiding accuracy and life. At present, there are two main types of guide rail structures for fine blanking presses: [0003] One type is a rolling guide, such as figure 1 As shown, the guide rail is made up of four rows of roller guide rails 11, and the rear two rows are installed in parallel on the rear side of the fuselage 13, and the front two rows form 45° with the front of the fuselage, and are symmetrically installed on the cover plate 15. This kind of guide rail has high guiding precision, but it belongs to the point contact guiding structure, the contact specific pressure is high, the rigidity and shock resistance are poor, a...
