Description

Technical Field

[0001] The utility model relates to the technical field of customized casing processing, and particularly relates to a customized casing processing device. Background Art

[0002] During building construction, when mechanical and electrical pipelines pass through walls or floors, sleeves need to be installed. Traditional sleeves are all prefabricated finished sleeves with fixed specifications. During construction, the situation where the pipeline does not match the sleeve often occurs. Therefore, additional filling is required inside the sleeve, which is rather troublesome. For this reason, for example, the patent with the publication number CN217096591U proposes a customized sleeve processing device. This device can bend steel plates at the construction site, and then weld the two sides of the steel plates in butt joints and then bend them into a cylindrical shape, so as to realize the on-site customized processing of sleeves. When using this device, the distance between the third roller shaft and the first and second roller shafts needs to be adjusted. When adjusting, workers need to rotate the first screw rod and the second screw rod simultaneously to adjust the heights of both ends of the third roller shaft. Therefore, it is very easy to occur the situation that the heights of both ends of the third roller shaft are inconsistent during adjustment, which may cause the screw rod to be stuck with the threaded connection sleeve. Moreover, when the heights of both ends of the third roller shaft are inconsistent, it is not parallel to the first and second roller shafts. In this case, bending the steel plate will result in a deformed sleeve finally obtained, affecting the quality of the sleeve.

[0003] Therefore, we design a customized sleeve processing device here. Summary of the Utility Model

The two rotating sleeves 42 are rotatably installed on the two ends of the roller shaft of the first round roller 41 respectively. The rotating sleeve 42 can be clamped in the groove between the bottom block 31 and the pressure plate 32 for clamping and fixing. After the bottom block 31 and the pressure plate 32 clamp the rotating sleeve 42, it will not hinder the rotation of the first round roller 41. The bolts 33 are removed, the pressure plate 32 is removed, and the rotating sleeve 42 can be taken out, so that the detachable roller 4 can be removed from the mounting member 3.

[0025] Working principle and usage process of the utility model: First, cut the steel plate to the required size, pass the cut steel plate through the gap between the bottom of the detachable roller 4 and the tops of the second circular roller 15 and the third circular roller 16. Rotate the handwheel 11 to drive the screw rod 9 to rotate, and then control the two moving plates 8 to move towards the middle simultaneously through the cooperation of the screw rod 9 and the nut 10, so as to lift the bottom plate 5 through the connecting rod 12. Under the guidance of the first sliding rod 2, the bottom plate 5 moves vertically upward, raising the second circular roller 15 and the third circular roller 16 to appropriate positions. Rotate the crank 18 to drive the second circular roller 15 and the third circular roller 16 to rotate, thereby bending the steel plate. Then, weld the two sides of the steel plate together.
