Sliding block guide and precision adjustment structure applied to hot blanking press machine

Abstract

The invention provides a sliding block guide and precision adjustment structure applied to a hot blanking press machine. The sliding block guide and precision adjustment structure comprises a left stand column, a right stand column, a front guide plate and a rear guide plate, wherein the left stand column and the right stand column are located at the left and right ends of a sliding block correspondingly, and front guide plate and the rear guide plate are located on the front and rear sides of the sliding block correspondingly. The front guide plate and the rear guide plate are connected withthe left stand column and the right stand column through guide plate adjusting bolts, two protruding blocks are symmetrically and vertically arranged at the left ends of the inner side walls of the front guide plate and the rear guide plate, and grooves corresponding to the protruding blocks are formed in the sliding block. The sliding block is slidably connected with the left stand column and thegrooves are slidably connected with the left side surfaces and the bottom surfaces of the protruding blocks, and the sliding block and the right stand column are arranged at intervals. By adopting the sliding block guide and precision adjustment structure, the sliding block guide and precision adjustment structure applied to the hot blanking press machine is reasonable in design, the degree of freedom of the sliding block in the nonmoving direction is limited, the running accuracy of the sliding block is guaranteed; the sliding block guide and precision adjustment structure applied to the hotblanking press machine can effectively prevent the sliding block from jamming in a guide rail gap after heating expansion, prolong the service life of mould and meet the market requirements.

Description

technical field

[0001] The invention relates to a slider guide and precision adjustment structure suitable for a hot blanking press. Background technique

[0002] Forging equipment, whether it is a crankshaft mechanical press, a screw press or a hydraulic press, the slide block is its most important component. Since the slider needs to carry a precise and expensive mold to forge and press the workpiece, not only must the qualified parts be processed, but also the service life of the mold and equipment must be extended as much as possible, so its movement accuracy is very high. The movement accuracy of the slider is the most important accuracy acceptance index of the press. These accuracy acceptance indexes are clearly stipulated in the relevant national, industry or enterprise standards, such as "GB / T 10924-2009 Closed Single and Double Point Press Accuracy ", "JB / T 5198-2007 Die Forging Screw Press Accuracy", "GB 9166-88 Four-column Hydraulic Press Accuracy", etc. There a...
