Abstract
The utility model belongs to the technical field of the roll technique and specifically relates to a modular carbide collars, including panel collars, rod collars, the threaded roll ring, key and nut, the panel collars is provided with the hole, the one end of panel collars is provided with the second major axis, and the other end is provided with first major axis, the key is installed to second major axis and first major axis, rod collars and threaded roll ring all are provided with the keyway, the rod collars passes through key fixed mounting on first major axis, the threaded roll ring is installed on the second major axis through the key, the tip of second major axis and first major axis is provided with the screw thread, the nut passes through the screw thread and installs on second major axis and first major axis, the utility model discloses can strengthen the intensity and the wearability of collars, the replacement wearing and tearing of being convenient for lead to condemned collars, improve the machining precision of collars, prolong the life of collars, once only accomplish the rolling of three kinds of steel, and labour saving and time saving improves production efficiency.
Description
Technical field
The utility model relates to roll technology field, especially a kind of Combined hard-alloy collars.
Background technology
Roll is the instrument making steel produce plastic deformation, it is the vitals determining rolling mill efficiency and mill bar quality, roll is the important spare part of steel rolling equipment, the pressure produced when organizing roll rolling is one to one utilized to roll stone roller steel, collars on present roll is all adopt monolithic construction, in use the wearing and tearing of collars are very serious, once reach the limit of wear, whole collars is scrapped, if collars length is longer simultaneously, due to self gravitation with when rotating, centrifugal force easily bends collars, collars machining accuracy is caused to reduce, and in prior art, once roll the rolling that can only complete a kind of steel, need to need during rolling variety classes steel to replace collars, hand labor intensity is large, waste time and energy, reduce production efficiency, some collars adopt bolt matable to be combined by variety classes collars, but the oversize bolt strength of length is low, service life is short, affect the service life of collars entirety, repair and replacement labor intensive material resources, affect the raising of productivity ratio.
Summary of the invention
In order to overcome the deficiency of prior art central roll loop technique, the utility model provides a kind of Combined hard-alloy collars, intensity and the wearability of collars can be strengthened, be convenient to replace the collars wearing and tearing and cause scrapping, improve the machining accuracy of collars, extend the service life of collars, the disposable rolling completing three kinds of steel, time saving and energy saving, enhance productivity.
The utility model solves the technical scheme that its technical problem adopts, a kind of Combined hard-alloy collars, comprise sheet material collars, bar collars, screw thread collars, key and nut, described sheet material collars is provided with endoporus, one end of described sheet material collars is provided with the second major axis, the other end is provided with the first major axis, described second major axis and the first major axis are provided with key, described bar collars and screw thread collars are provided with keyway, described bar collars is fixedly mounted on the first major axis by key, described screw thread collars is arranged on the second major axis by key, the end of described second major axis and the end of the first major axis are provided with screw thread, described nut is arranged on the second major axis and the first major axis by screw thread.
Not in the same horizontal line, the position of the second major axis fitting key is in bottom, and the position of described first major axis fitting key is at top at the position of described second major axis and the first major axis fitting key.
The beneficial effects of the utility model are, a kind of Combined hard-alloy collars, bar collars and screw thread collars are fixedly mounted on the two ends of sheet material collars by key, and the two ends of sheet material collars hold out against fixing by nut simultaneously, can strengthen intensity and the wearability of collars, be convenient to replace the collars wearing and tearing and cause scrapping, improve the machining accuracy of collars, extend the service life of collars, the disposable rolling completing three kinds of steel, time saving and energy saving, enhance productivity.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is assembling partial sectional view of the present utility model.
Fig. 2 is the second view of the present utility model.
Fig. 3 is the generalized section of sheet material collars.
1. sheet material collars, 2. bar collars, 3. screw thread collars, 4. key, 5. keyway, 6. nut, 7. screw thread, 8. endoporus, 9. the first major axis, 10. the second major axis in figure.
Detailed description of the invention
With reference to accompanying drawing, a kind of Combined hard-alloy collars, comprise sheet material collars 1, bar collars 2, screw thread collars 3, key 4 and nut 6, described sheet material collars 1 is provided with endoporus 8, one end of described sheet material collars 1 is provided with the second major axis 10, the other end is provided with the first major axis 9, described second major axis 10 and the first major axis 9 are provided with key 4, described bar collars 2 and screw thread collars 3 are provided with keyway 5, described bar collars 2 is fixedly mounted on the first major axis 9 by key 4, described screw thread collars 3 is arranged on the second major axis 10 by key 4, the end of described second major axis 10 and the end of the first major axis 9 are provided with screw thread 7, described nut 6 is arranged on the second major axis 10 and the first major axis respectively by screw thread 7.
The position of described second major axis 10 and the first major axis 9 fitting key 4 is not in the same horizontal line, the position of the second major axis 10 fitting key 4 is in bottom, the position of described first major axis 9 fitting key 4 is at top, bar collars 2 can be ensured, screw thread collars 3 and sheet material collars 1 keep synchronous axial system, can ensure again the intensity of sheet material collars 1.
