AI Technical Summary
The roller seam adjustment machinery on the cone box lacks the positive and negative locking function, which causes the roller seam to rotate easily when subjected to rolling force, resulting in the roller seam becoming larger, resulting in unqualified rolling size, and may even cause steel piles or roller box burning.
A new type of roller slot adjustment device is designed, adopting a structure with a locking function in the front and reverse directions. By installing a stop block and a knob plunger on the adjustment shaft, the locking function is achieved, ensuring that the roller slot is within the required size range.
It effectively prevents the roller seams from becoming larger due to rotation during the rolling process, ensures the stability of the rolling size, avoids the situation of stacking steel and roll box burning boxes, and extends the service life of the equipment.

[0003] To form a complete rolling mill, a roll box for rolling is also required to be installed on the cone box to reduce the diameter of the wire rod. There is a set of roll gap adjustment device on the roll box, with a regulating gear installed at each end. There is also a set of adjustment device for roll gap adjustment on the cone box. There is a gear on the adjustment device that meshes with the one on the roll box. After the roll box is installed on the cone box, the two gears cooperate with a gap of about 0.3 mm. Under the operating state of the equipment, the power can be transmitted to the gear of the roll gap adjustment device of the roll box by rotating the adjustment device on the cone box to achieve the adjustment of the roll gap size of the roll box.
[0004] At present, due to the lack of positive and negative locking functions in the roll gap adjustment mechanism on the cone box, the roll gap adjustment device on the roll box is prone to rotation under the rolling force, resulting in an increase in the roll gap, making the rolling size unqualified. In severe cases, it may cause the downstream rolling mill to have a steel piling phenomenon due to unqualified incoming material size. In extreme cases, it may even cause the roll box to burn out.

[0005] To solve the problems raised in the above background art, the utility model provides a novel roll gap adjustment device, which has the characteristics of having positive and negative direction locking functions, so that the roll gap is always within the required size range.
[0006] To achieve the above object, the utility model provides the following technical solution: A novel roll gap adjustment device includes a bearing seat. An adjustment shaft is arranged inside the bearing seat. The two ends of the adjustment shaft are respectively connected to the bearing seat through bearings. One end of the adjustment shaft is connected with a gear. A gland is installed at one end of the bearing seat away from the gear. An extension part is connected to the side surface of the gland. The gland and the extension part are of an integrally formed structure. A knob plunger is connected to the extension part. A stop block located inside the extension part is connected to the adjustment shaft. There are 12 rectangular grooves arranged in a circular array on the circumference of the stop block.
[0007] To install the knob plunger, further, the extension part is provided with an installation hole for installing the knob plunger.
[0008] To prevent water and other substances from entering the inside of the adjustment device, further, a skeleton oil seal ring is arranged between the gland and the adjustment shaft.
[0009] In order to achieve the adjustment of the roll gap more precisely, further, there are two installation holes in total. The central axis of one installation hole coincides with the central horizontal line of the adjusting shaft, and the other installation hole is arranged on the other side, and the included angle between the central axis and the central horizontal line of the adjusting shaft is 7.5°.
