Description

[0001] The utility model relates to the technical field of surfacing of mirror rollers, and particularly relates to a two-way surfacing device for an anti-flexure deformation mirror roller. Background Technique

[0002] In the field of mirror roller manufacturing, anti-flexure deformation is a crucial performance index. In order to improve the anti-flexure deformation performance of the mirror roller, a surfacing process is usually required on the surface of the mirror roller to increase its hardness, wear resistance and anti-deformation ability. Different from unidirectional surfacing, in the process of two-way surfacing, the heat input and cooling rate in two directions of the surfacing layer are different, resulting in differences in the microstructural properties of the surfacing layers in two directions. This difference makes the two-way surfacing have better anti-deformation and anti-cracking properties, but at the same time requires more materials and welding time.

By the above method, in the roll two-way surfacing repair device of the utility model, two welding torches can work simultaneously, move from the middle of the roll to both ends for surfacing, realize two-way surfacing, have high working efficiency, flexible operation, reduce labor costs and improve operation safety.

[0004] Although the above patent realizes two-way surfacing by two welding torches working simultaneously, however, the two welding torches are driven by a driving device to cooperate with the guide rail for telescopic adjustment, and are all limited on the same horizontal line, making it difficult to effectively surfacing irregular points on the arc surface, and the flexibility in use is insufficient. Therefore, the utility model provides a two-way surfacing device for an anti-flexure deformation mirror roller. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-5 , the present utility model provides a technical solution: a two-way surfacing device for a flexure-resistant mirror roller, including a frame body 1, on which a two-way surfacing mechanism 2 is arranged for surfacing the surface of the mirror roller. The two-way surfacing mechanism 2 includes:

[0027] The first adjustment assembly 21 is arranged at the bottom of the frame 1 and includes a first oil cylinder 211 fixedly installed at the bottom of the frame 1. The top end of the telescopic rod of the first oil cylinder 211 is fixedly provided with a first base plate 212. The upper part of the first base plate 212 is rotatably installed with a first internal gear ring 213. The inner side of the first internal gear ring 213 is meshed and connected with a first gear 214. The bottom of the first base plate 212 is fixedly installed with a first motor 215. The power output end of the first motor 215 is connected with the power input end of the first gear 214. When the first motor 215 is powered on, it drives the first gear 214 to rotate, and then drives the first internal gear ring 213 to rotate through the meshing action with the first internal gear ring 213, thereby adjusting the surfacing angle of the welding torch 233 on the first internal gear ring 213.

[0028] The second adjustment assembly 22 is arranged at the top of the frame 1 and includes a second oil cylinder 221 fixedly installed at the top end of the frame 1. The end of the telescopic rod of the second oil cylinder 221 is fixedly provided with a second base plate 222. The upper part of the second base plate 222 is rotatably installed with a second internal gear ring 223. The inner side of the second internal gear ring 223 is meshed and connected with a second gear 224. The bottom of the second base plate 222 is fixedly installed with a second motor 225. The power output end of the second motor 225 is connected with the power input end of the second gear 224. By driving the second gear 224 to rotate through the second motor 225, the welding torch 233 on it is driven to adjust the angle through the second internal gear ring 223.

[0029] Two groups of welding assemblies 23 are respectively arranged at the tops of the first internal gear ring and the second internal gear ring and are used for bidirectional surfacing of the mirror roller.

[0030] In this embodiment, the two groups of welding assemblies 23 include guide plates 231 respectively welded on the first internal gear ring 213 and the second internal gear ring 223. A third oil cylinder 232 is installed on the upper part of the guide plate 231. The end of the telescopic rod of the third oil cylinder 232 is installed with a welding torch 233.

[0031] In this embodiment, several groups of L-shaped blocks are fixed on the upper parts of the first base plate 212 and the second base plate 222, and the first internal gear ring 213 and the second internal gear ring 223 are limited by the circumferential distribution of the L-shaped blocks.

[0032] In this embodiment, several groups of clamping rods 3 distributed in a circle are fixed on the lower part of the frame 1 and are used for clamping and fixing the mirror roller. Through holes are provided at the central positions of both the first base plate 212 and the second base plate 222.

[0033] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0034] During operation, the mirror roller workpiece is fixed between multiple sets of clamping rods 3. According to the welding point positions of the mirror roller, the first oil cylinder 211 and the second oil cylinder 221 drive the first substrate 212 and the second substrate 222 to move up and down respectively, and then drive the welding assembly 23 to approach the welding point position. Immediately afterwards, the first motor 215 is powered on to drive the first gear 214 to rotate, and then drives the first internal gear ring 213 to rotate through the meshing action with it, and then adjusts the surfacing angle of the welding torch 233 on the first internal gear ring 213. Similarly, the second motor 225 drives the second gear 224 to rotate, and then drives the welding torch 233 on it to adjust the angle through the second internal gear ring 223. Finally, the third oil cylinder 232 pushes the welding torch 233 to the welding point of the mirror roller, and the two welding torches 233 perform surfacing simultaneously. Due to the differences in heat input and cooling rate in two directions of the surfacing layer, the microstructures and properties of the surfacing layers in the two directions are different, and then the mirror roller has better anti-flexural deformation performance.
