Problems solved by technology
[0003] This application is to solve the problem that the eccentric shaft sleeve of the existing forging press and the installation hole of the support seat are fitted with a small gap. It is precisely because of the small gap that it is difficult to repeatedly debug the shaft sleeve during installation, and the installation is very difficult. problem, this application designs a forging press eccentric shaft sleeve installation structure and its installation method, which are specifically:

Abstract
The invention relates to an eccentric shaft sleeve mounting structure of a forging press and a mounting method thereof, and belongs to the field of presses. The mounting structure comprises a supportbase, wherein the support base is provided with a mounting hole; the cross section profile of the mounting hole includes a main bearing section and a support section; the main bearing section is positioned above the support section, and is an arc section with the same diameter with an outer circle of a shaft sleeve; the diameter of the arc section is the same with the diameter of the outer circleof the shaft sleeve; when the shaft sleeve is mounted in the mounting hole and bonded with the inner surface of the main bearing section, a gap is formed between the support section and the outer surface of the shaft sleeve; a first embedding groove is formed in the inner wall of the mounting hole corresponding to the support section; an embedding block is inserted in the first embedding groove and a second embedding groove; the main bearing section is positioned on the upper side, and the support section is positioned on the lower side; the main bearing section is the arc section with the same diameter with the outer circle of the shaft sleeve; and when the shaft sleeve is mounted in the mounting hole and bonded with the inner surface of the main bearing section, the gap is formed betweenthe support section and the outer surface of the shaft sleeve to realize large-gap installation of the shaft sleeve, so that the shaft sleeve assembly difficulty is reduced.
Description
technical field [0001] The invention relates to the field of forging presses, in particular to an installation structure of an eccentric shaft sleeve of a forging press and an installation method thereof. Background technique [0002] Forging presses are hydraulic presses or mechanical presses for forging hot metals. They are widely used in precision forging, precision blanking for gear processing, motor processing, bearing processing, etc. The forging press is mainly a forging machine that uses a motor to rotate, transmits it to the eccentric shaft (that is, the crankshaft) through a gear, and then drives the slider to reciprocate up and down along the guide rail through a connecting rod to shape the blank. Among them, the eccentric shaft is an indispensable power transmission component on the forging press. For the installation of the eccentric shaft, such as Figure 1-Figure 2 As shown, at present, there is mainly a mounting hole on the supporting seat of the fuselage. Th...
