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 defor

Embodiment 1

[0025] A circulating feeding roller of a press is installed on a frame assembled from a base 3, two side plates 4 and a top plate 5. The circulating feeding roller includes a lower roller 1-2 with a fixed height and a height-adjustable The upper roller 1-1, the position of the lower roller 1-2 is at the bottom, and its two ends are respectively installed on the roller seats 12 of the side plates 4 at both ends of the frame through bearings, the position of the upper roller 1-1 is at the top, and its The two ends are respectively installed on the sliders 7 of the side plates 4 at both ends of the frame through bearings. The roller base 12 is fixed on the side plate 4, so the height position of the lower roller 1-2 is fixed, and the slide block 7 is slidingly fitted on the side plate 4, so the lifting action of the slide block 7 on the side plate 4 It can simultaneously drive the upper roller 1-1 to adjust the height. The slider 7 is connected and controlled by the cylinders 6 ...

Embodiment 2

[0032] This embodiment discloses a method for adjusting the circulating feeding roller of a press, which is used to adjust the circulating feeding roller of a press described in Embodiment 1, including the following steps:

[0033] S1. Loosen the lock nut and lock bolt of the support roller assembly, and adjust the gap between the support roller and the circulating feeding roller by screwing the length of the adjustment bolt. Measure the deformation of the circulating feeding roller until the error of the data on both sides does not exceed the predetermined value. After meeting the requirements, tighten the lock nut and lock bolt.

[0034] S2. After the adjustment, put a certain width of carbon paper between the upper and lower rollers, roll it through the lower and upper rollers for one rotation, take out the carbon paper to check the indentation, if the indentation in the middle part is lighter, repeat the above steps, and feed to the circulation Adjust the protruding direct...

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...
