Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of casting and rolling equipment, and specifically relates to an inclined casting and rolling mill base. Background Technology
[0002] During service, inclined casting and rolling mills are subjected to large rolling forces, wear, and thermal fatigue for extended periods, requiring regular roll replacements. To ensure roll replacement efficiency and rolling accuracy, the base structure of the inclined casting and rolling mill has very high requirements.
[0003] Currently, in tilting casting and rolling mills, the archway tilting device consists of a frame, tilting cylinder, tie rod, and support plate. During the casting and rolling process, the tilting hydraulic cylinder pushes the archway to the required angle, where it is supported by outriggers. However, the tilting of the casting and rolling mill archway exerts a certain impact force on the outriggers, causing some damage. Long-term use weakens the supporting capacity of the outriggers. Furthermore, since outriggers are usually installed in pairs, varying degrees of damage can result in inconsistent support capacity for the casting and rolling mill archway, making the archway less stable.
[0004] Therefore, how to reduce the damage to the outriggers during support and improve the efficiency of quickly replacing vulnerable parts are issues that need to be explored. Utility Model Content

[0011] Optionally, a sliding copper plate is also provided between the grooved slide rail and the support leg.
[0012] Optionally, the system also includes a tilting hydraulic cylinder for the archway, which is connected to the tilting base via a pin. The cylinder head of the tilting hydraulic cylinder is connected to the tilting connecting handle via a pin. The pin is equipped with a cotter pin for disassembly. The tilting connecting handle is connected to the archway of the casting and rolling mill via fasteners.
[0013] Optionally, the mandrel mounting base includes an upper support base and a lower support base, wherein the lower support base is fixedly connected to the mandrel base, and the upper support base and the lower support base are connected by bolts. The upper end of the lower support base has a semi-circular hole with its axis horizontal and the opening direction of the semi-circular hole is upward, and the lower end of the upper support base has a semi-circular hole with its axis horizontal and the opening direction of the semi-circular hole is downward. The semi-circular holes of the lower support base and the upper support base together form a circular shaft hole, and the mandrel is installed in the shaft hole.

[0016] Optionally, the mandrel foundation is connected to the anchor bolts and fixed to the ground foundation with grouting.
[0017] This utility model has the following beneficial effects:
[0018] The inclined casting and rolling mill base of this application uses an upper pad to fix the pad plate to the upper end of the support leg, which can buffer the downward pressure of the casting and rolling mill arch and reduce the instantaneous pressure on the support leg.
[0019] Furthermore, the distance between its outriggers is adjustable, allowing the outrigger positions to be adjusted as needed, ensuring the outriggers are appropriately positioned within the casting and rolling mill stand.

[0026] This application provides an inclined casting and rolling mill base, including a mandrel base and a tilting and lateral shifting base. The mandrel base is used to be rotatably connected to the casting and rolling mill arch, so that the casting and rolling mill arch can rotate around the mandrel. The tilting and lateral shifting base is used to push the casting and rolling mill arch to rotate and push the support legs to move.
[0027] Among them, such as Figure 1 As shown, the mandrel base includes a mandrel base 1, an upper support 2, a lower support 3, and a shaft end baffle 4. The mandrel base 1 can be a welded structural component, with its base plate connected to pre-embedded anchor bolts via round holes. Secondary grouting is then used to fix the mandrel base to the ground foundation.
[0028] The lower support seat 3 is welded and fixed to the top plate of the mandrel base 1. The upper support seat 2 is connected to the lower support seat 3 by bolts. The upper end of the lower support seat 3 has a semi-circular hole with its axis horizontal and the opening direction of the semi-circular hole is upward. The lower end of the upper support seat 2 has a semi-circular hole with its axis horizontal and the opening direction of the semi-circular hole is downward. The semi-circular holes of the lower support seat 3 and the upper support seat 2 together form a circular shaft hole. The upper support seat 2 and the lower support seat 3 are collectively referred to as the mandrel mounting seat. The mandrel of the casting and rolling mill stand can be installed in this shaft hole. When the mandrel of the casting and rolling mill stand is inserted into the shaft hole, the casting and rolling mill stand can rotate around the mandrel. More specifically, the mandrel of the casting and rolling mill stand can be installed in the shaft hole, so that the casting and rolling mill stand can rotate around the mandrel. A shaft end baffle 4 is provided at the end of the lower support seat 3.
