Abstract

The invention relates to an all-hydraulic die forging hammer which comprises a U-shaped lathe bed, wherein the U-shaped lathe bed is provided with an all-hydraulic power head; the all-hydraulic power head comprises a working cylinder; a hammer lever is mounted in the working cylinder; the lower end of the hammer lever is connected with a sliding block; guide grooves are respectively formed in the first side surface and the second side surface, which are contacted with the lathe bed, of the sliding block; each guide groove is internally provided with a groove bottom surface, as well as a first guide surface and a second guide surface arranged on the groove bottom surface, wherein both the first guide surface and the second guide surface are inclined planes; guide rails are arranged on the opposite inner side wall surfaces of the U-shaped lathe bed respectively, and are inserted into the guide grooves to be in sliding fit with the guide grooves. The all-hydraulic die forging hammer has the advantage of high guide precision, and the die forging precision is not affected by a temperature rise.

Description

technical field [0001] The invention relates to a full hydraulic die forging hammer. Background technique [0002] A full hydraulic die forging hammer is disclosed in the prior art, which includes a U-shaped integral bed, on which there is a full hydraulic power head, and the full hydraulic power head has a working cylinder, the working cylinder is covered with an outer cylinder, and the working cylinder is connected to work There is an annular hydraulic oil channel between the working cylinder and the outer cylinder. The upper end of the annular hydraulic oil channel is connected to the pressure oil port, and the lower end is connected to the rod chamber of the working cylinder. The working cylinder and the outer cylinder are connected to the oil tank through the integrated block. The fuel tank is set outside the outer cylinder and fixed on the upper end of the outer cylinder through the integrated block. The working parts connected to the working cylinder include: a hamme...
