Circulating feeding roller of pressing machine and adjusting method of circulating feeding roller

Abstract

The invention relates to a circulating feeding roller of a pressing machine. The circulating feeding roller of the pressing machine comprises a lower roller and an upper roller which are arranged up and down and have the same structure, and is characterized in that each of the upper roller and the lower roller comprises a working section in the middle, transition conical sections extending outwards along the two sides of the working section and supporting sections extending outwards along the transition conical sections on the two sides; the upper portion of the upper roller is provided with two supporting roller assemblies, the two supporting roller assemblies are detachably installed on an upper sliding base and act on the supporting sections on the two sides of the upper roller downwards respectively, the lower portion of the lower roller is provided with the two supporting roller assemblies, and the two supporting roller assemblies are detachably installed on the base of a frame and act on the supporting sections on the two sides of the lower roller upwards respectively. The two ends of the upper sliding base are fixedly connected with the sliding blocks on side plates. According to the circulating feeding roller of the pressing machine and an adjusting method of the circulating feeding roller, pressure between circulating feeding rollers can be adjusted by additionally arranging an adjusting supporting rollers, service life is long, cost is low, and very high practicability and economic value are achieved.

Description

technical field [0001] The invention relates to the technical field of sheet material conveying, in particular to a circulating feeding roller of a press and an adjustment method thereof. Background technique [0002] The working process of the circulating feeding roller at the front end of the press: the upper roller is driven upward by the cylinder, the gap leaks between the upper and lower rollers together, the sheet passes through the gap, the cylinder drives the upper roller to fall, and the gap between the two rollers The steel plate is pressed tightly, and the upper and lower rollers rotate to drive the steel plate forward to the press. Therefore, whether the steel plate can be fed and conveyed stably depends on whether the pressure exerted by the upper and lower rollers on the middle steel plate is balanced. Once the contact pressure of the upper and lower rollers is uneven, the steel plate will deflect to the side with greater force, resulting The steel plate dev...

Problems solved by technology

Therefore, whether the steel plate can be fed and conveyed stably depends on whether the pressure exerted by the upper and lower rollers on the middle steel plate is balanced. Once the contact pressure of the upper and lower rollers is uneven, the steel plate will deflect to the side with greater force, resulting The steel plate deviates or crushes the steel plate

[0003] Existing rollers are generally made of polyurethane materials with medium height, arc-shaped (and other shapes) steel chrome-plated materials, and rollers made of polyester materials are unstable in feeding, easy to deviate, wear quickly, and have a short life; arc-shaped steel rollers It is required that the deformation of the rollers is appropriate (that is, the deformation of the rollers just satisfies the uniform pressure exerted on the steel plate in the length direction of the upper and lower rollers) and proper rigidity, so as to ensure a good fit between the upper and lower rollers after compression, and for larger lengths ( more than 2 meters) of the roller is easier to deform

Therefore, to ensure that the roller exerts pressure on the steel plate in a balanced manner in the axial direction, there are great difficulties in both manufacturing and installation adjustment of the roller. In practice, no matter which cylinder is adjusted on the left or right, the pressure on the roller cannot be made uniform, and the part with excessive pressure is easy to be crushed steel plate, resulting in waste
