Abstract
Description
Technical Field
[0001] This utility model relates to the field of galvanized barrel edge rolling technology, specifically a limiting edge rolling tool for processing galvanized barrels. Background Technology
[0002] In the production and processing of galvanized drums, the edge-rolling process is a crucial step in ensuring product quality and usability. The limiting edge-rolling fixture used in galvanized drum processing is the core equipment for achieving precise edge rolling; its performance directly affects the sealing performance, appearance quality, and production efficiency of the drum. The rational design and application of the limiting edge-rolling fixture can effectively solve problems such as positioning deviations and uneven edge rolling inherent in traditional edge-rolling methods, driving the galvanized drum processing industry towards higher efficiency and precision.
[0003] However, existing galvanized drum processing fixtures for edge curling require the drum to be placed on the worktable before the curling operation. The drum body and lid are then precisely positioned using a drum body positioning component and a lid positioning device. The edge is then initially bent to a certain angle by the curling rollers, and the forming rollers form the edge according to the preset curling shape. During the curling process, both the curling rollers and the forming rollers rub against the galvanized drum. Because the galvanizing fixture cannot lubricate the curling components and the galvanized drum, this results in significant wear and affects the smoothness and stability of the curling, thus reducing the service life of the galvanizing fixture. To address this issue, we propose a galvanized drum processing fixture for edge curling. Utility Model Content

[0022] Please see Figure 1-4 This utility model provides a technical solution: a limiting edge-rolling fixture for processing galvanized buckets, including an edge-rolling body 1. An oil storage tank 101 and a rotary motor 19 are installed inside the edge-rolling body 1. An oil pump 102 is fixedly connected to one side of the oil storage tank 101. An oil delivery pipe 15 is fixedly connected to the output end of the oil pump 102. An oil inlet flange 14 is fixedly connected to one end of the oil delivery pipe 15. Adjustment grooves 5 are symmetrically opened on the top of the edge-rolling body 1. A sliding plate 6 is movably connected to the top of the edge-rolling body 1 through the adjustment grooves 5. An adjustment frame 7 is fixedly connected to the top of the sliding plate 6. A lifting groove 8 is opened on one side of the adjustment frame 7. A lifting plate 9 is movably connected to one side of the adjustment frame 7 through the lifting groove 8. An edge-rolling frame 10 is fixedly connected to one side of the lifting plate 9. An edge-rolling shaft 11 is installed on one side of the edge-rolling frame 10 through a bearing. An oil cavity 1101 is opened inside the edge-rolling shaft 11.
[0023] Furthermore, the drive end of the rotary motor 19 is fixedly connected to the limiting cylinder 16. The limiting cylinder 16 is equipped with a telescopic rod 18. One end of the telescopic rod 18 is fixedly connected to the limiting plate 17. By fitting the galvanized bucket onto the outside of the limiting plate 17 and then starting the telescopic rod 18, the telescopic rod 18 drives the limiting plate 17 to move outward. At this time, the limiting plate 17 will move outward, thereby clamping and fixing the outside of the galvanized bucket.
[0024] Furthermore, an adjustment motor 3 is installed on both sides of the edge-rolling body 1. An adjustment screw 301 is fixedly connected to the drive end of the adjustment motor 3. An adjustment nut seat 302 is threadedly connected to the outer side of the adjustment screw 301. The adjustment nut seat 302 is fixedly connected to the sliding plate 6. By starting the adjustment motor 3, the adjustment motor 3 drives the adjustment screw 301 to rotate, and the adjustment nut seat 302 drives the sliding plate 6 to slide through the adjustment groove 5, thereby adjusting the position of the adjustment frame 7 so that the forming roller 12 and the edge-rolling roller 13 are against the edge-rolling position of the galvanized barrel.
[0025] Furthermore, a lifting motor 701 is installed inside the adjusting frame 7. The driving end of the lifting motor 701 is fixedly connected to a lifting screw 702. The outer side of the lifting screw 702 is threadedly connected to a lifting nut seat 703. The lifting nut seat 703 is fixedly connected to the lifting plate 9. By starting the lifting motor 701, the lifting motor 701 drives the lifting screw 702 to rotate, and the lifting nut seat 703 drives the lifting plate 9 to adjust up and down through the lifting groove 8, so that the forming roller 12 and the edge rolling roller 13 are located at the edge rolling position of the galvanized barrel.
[0026] Furthermore, four edge-rolling shafts 11 are provided. Two edge-rolling shafts 11 are fixedly connected to one end of forming rollers 12, and the other two edge-rolling shafts 11 are fixedly connected to one end of edge-rolling wheels 13. Oil ports 1301 are opened on the outer side of both forming rollers 12 and edge-rolling wheels 13. All four edge-rolling shafts 11 are movably connected to oil inlet flanges 14. The limiting cylinder 16 is driven to rotate by a rotary motor 19, and the limiting cylinder 16 drives the galvanized drum to rotate through the limiting plate 17. At this time, the edge-rolling wheels 13 and forming rollers 12 perform edge-rolling operations on the galvanized drum.
[0027] Furthermore, support legs 2 are fixedly connected to the four corners of the bottom of the hemming body 1, and limit blocks 4 are fixedly connected to the top of the hemming body 1. The limit blocks 4 can support the galvanized bucket, and the support legs 2 make the hemming fixture more stable.
[0028] Working Principle: After the utility model is installed, first check the installation, fixation, and safety protection. When using the limiting and rolling edge fixture for galvanized bucket processing, the worker places the galvanized bucket on the outside of the limiting plate 17, and then starts the telescopic rod 18. The telescopic rod 18 drives the limiting plate 17 to move outward, thus clamping and fixing the outside of the galvanized bucket. Then, the lifting motor 701 is started, which drives the lifting screw 702 to rotate. The lifting nut seat 703 drives the lifting plate 9 to adjust up and down through the lifting groove 8, so that the forming roller 12 and the rolling edge wheel 13 are located at the rolling edge position of the galvanized bucket. At the same time, the adjusting motor 3 is started, which drives the adjusting screw 301 to rotate. The adjusting nut seat 302 drives the sliding plate 6 to slide through the adjusting groove 5, thereby adjusting the position of the adjusting frame 7, so that the forming roller 12 and the rolling edge wheel 13 are positioned at the rolling edge position of the galvanized bucket. The roller 13 rests against the edge-rolling position of the galvanized drum. After the position is adjusted, the rotary motor 19 drives the limiting cylinder 16 to rotate, and the limiting cylinder 16 drives the galvanized drum to rotate through the limiting plate 17. At this time, the edge-rolling roller 13 and the forming roller 12 perform edge-rolling operations on the galvanized drum. During the edge-rolling process, the oil pump 102 is started, and the oil pump 102 draws lubricating oil from the oil storage tank 101. The lubricating oil is delivered to the oil inlet flange 14 through the oil delivery pipe 15, and then delivered to the oil chamber 1101 of the edge-rolling shaft 11 through the oil inlet flange 14. Afterward, it is discharged from the oil port 1301 on the edge-rolling roller 13 and the forming roller 12, thereby lubricating the edge-rolling roller 13, the forming roller 12, and the edge-rolling position of the galvanized drum. After the edge-rolling is completed, the galvanized drum can be removed as needed. This completes the use of this utility model. This utility model has a simple structure and is safe and convenient to use.
