Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crushers, in particular to an adjusting ring of a large cone crusher. Background Art
[0002] The adjusting ring is one of the important parts of the cone crusher and is installed inside the crusher. However, in large cone crushers, the adjusting ring has a large diameter, which makes it difficult to control the size of the adjusting ring during the manufacturing process. There are many reasons for the deformation, such as the material of the blank, the geometric shape of the parts, and the production conditions. It is a manufacturing problem of a complex system. The complexity and diversity of influencing factors make it one of the bottlenecks in the manufacturing of mechanical products, and it is also a global problem that has long been concerned and unsolved by manufacturing companies in various countries around the world.
[0003] In addition, the adjustment ring is manufactured using large steel structure welded parts, which have welding residual stress inside. These residual stresses make the workpiece easy to deform and damage during processing and shipping, which does not meet the user's requirements for geometric accuracy and other aspects. Therefore, in order to control deformation, the residual stress level of the structural blank must be controlled first; at the same time, in-depth research is conducted on issues such as process control and safety correction of deformation. On the one hand, the relevant basic theory is still weak, and on the other hand, the process technology level of structural mechanical manufacturing is relatively backward.
[0004] Therefore, it is necessary to improve the structure of the adjusting ring of the large cone crusher in order to reduce the residual stress of the adjusting ring structural parts of the cone crusher. Summary of the invention
[0005] The technical problem to be solved by the utility model is to provide an adjusting ring for a large cone crusher, reduce the residual stress of the adjusting ring structural parts of the cone crusher, reduce the influence on the strength, life and dimensional stability, improve the inner diameter dimensional accuracy, ensure the dimensional accuracy of the cylindrical parts, improve the production efficiency of the adjusting ring, and ensure the stability of its product quality.
[0006] The utility model provides an adjusting ring for a large cone crusher, comprising a flange plate, a straight cylinder is arranged on the flange plate, a plurality of upright columns are vertically connected to the outer wall of the straight cylinder, an auxiliary correction block is arranged on the upper part of the inner wall of the straight cylinder, the auxiliary correction blocks correspond to the upright columns one by one and are located on both sides of the straight cylinder, a plurality of auxiliary positioning blocks are arranged on the flange plate, the auxiliary positioning blocks are arranged inside the straight cylinder, and a plurality of mounting holes are arranged on the flange plate.
[0007] Preferably, there are four upright columns evenly distributed on the outer wall of the straight cylinder.
[0008] Preferably, the outer diameter of the flange is larger than the outer diameter of the straight cylinder, a groove is provided on the outer edge of the flange, and the lower end of the upright column is arranged in the groove.
[0009] Preferably, a plurality of guide grooves are radially provided on the flange, and the auxiliary positioning block is movably mounted on the guide grooves, and a locking bolt is provided on the auxiliary positioning block.
[0010] Preferably, the guide groove is provided with a scale.
[0011] Preferably, the angle between the central axis of the straight cylinder and the line connecting the central axes of the auxiliary positioning block and the upright column is 10°.
[0012] Working principle of the utility model: The large cone crusher adjustment ring of the utility model is provided with an auxiliary positioning block. During processing, a point-by-point positioning method is adopted. First, the inner diameter position line of the straight cylinder is drawn on the plane of the flange, and then a circle of auxiliary positioning blocks is spot-welded near the flange dimension line. The inner diameter of the straight cylinder is adjusted point by point to the position line of the flange straight cylinder using a wedge, and then spot-welded for positioning. An auxiliary correction block is set, and an anti-deformation correction block is used for control to prevent welding deformation between the straight cylinder and the column. Before welding the weld between the straight cylinder and the column, an auxiliary correction block is welded on the inner side of the straight cylinder on the back of the upright column, and then the straight cylinder and the upright column are welded. After the adjustment ring is cooled, the auxiliary correction block is cut off, which effectively prevents bending deformation of the weld between the straight cylinder and the upright column. Preferably, in order to facilitate the positioning and adjustment of the auxiliary positioning block, a plurality of guide grooves can be radially provided on the flange, and the auxiliary positioning block is movably mounted on the guide groove. The auxiliary positioning block is provided with a locking bolt to complete.
[0013] Beneficial effects of the utility model: The large cone crusher adjusting ring of the utility model is convenient for accurate positioning and correction of the straight cylinder in the processing link, reducing the residual stress of the cone crusher adjusting ring structure, reducing the influence on the strength, life and dimensional stability, improving the inner diameter dimensional accuracy, ensuring the dimensional accuracy of the cylindrical parts, improving the production efficiency of the adjusting ring, and ensuring the stability of its product quality. The device is used to achieve a large cone crusher adjusting ring with a wall thickness of 25mm and an inner diameter of Φ4740mm. The dimensional tolerance can be controlled within ±4mm, exceeding the tolerance value of ±5 in GB / T19804-2005 when the linear dimension is >4000~8000mm; the adjusting ring has no marks on its surface after manufacturing and correction, and the corresponding weld dimensional tolerance is controlled within ±0.5mm.
