Abstract
The invention discloses a saw arbor structure of a hot sawing machine, which comprises a saw arbor main body. A left end of the saw arbor main body is used for arranging a first support bearing, while a right end thereof is used for arranging a second support bearing and a saw bit installing disk. The middle of the saw arbor main body is a positioning shaft shoulder section. The saw arbor structure is characterized in that on the positioning shaft shoulder section, the saw arbor main body is sleeved with a cylinder to form a positioning shaft shoulder; and the saw arbor diameter at the sleeving position of the cylinder is equal to or less than that at the position of the second support bearing. The saw arbor structure of the hot sawing machine of the invention has the advantages of convenient and rapid disassembly and replacement when the second support bearing is replaced, saves mass disassembling time and indirectly improves the production efficiency. In the assembling and disassembling process, the whole saw bit installing disk is maintained fixed so as to guarantee the assembly precision of the saw bit installing disk is the original assembly precision and guarantee the performance and the working quality of the hot sawing machine are not influenced in the subsequent using process.
Description
Technical field
The present invention relates to a kind of hot-metal sawing machine, especially a kind of saw arbor structure of hot sawing machine.
Background technology
Hot-metal sawing machine is the jumbo of a kind of special-purpose cutting of cutting after a kind of hot-rolled steel moulding, its mainly by base device, traversing walk wheel apparatus, down carriage apparatus, go up carriage apparatus, advance saw device, advance mandrel and assembly.Wherein, hot-metal sawing machine mandrel place existing structure is, comprise the mandrel body, described mandrel body left end is used to install first spring bearing, the first spring bearing left end is used to install shaft coupling, mandrel body right-hand member is used to install second spring bearing and saw blade mounting disc, fixedly mount saw blade in the saw blade mounting disc again, be location shaft shoulder section in the middle of the mandrel body, wherein said location shaft shoulder Duan Youyi the positioning step shaft shoulder constitutes, the usefulness of first spring bearing and the second spring bearing location when effect of the positioning step shaft shoulder is the confession assembling.
This existing mandrel place structure since when work mandrel and the saw blade mounting disc between need to transmit bigger moment, so be that the way that the employing hot charging is joined is interference fitted in the saw blade mounting disc on the mandrel during assembling, the magnitude of interference is bigger.Simultaneously, this existing mandrel, saw blade is stressed bigger during owing to work, and the reaction force that causes second spring bearing adjacent with the saw blade mounting disc to be born is bigger, so second spring bearing is a consumable accessory.Like this, in the hot-metal sawing machine course of work, second spring bearing wearing and tearing back needs dismounting saw blade mounting disc earlier when changing, and be hot interference fit between saw blade mounting disc and the mandrel, so must the saw blade mounting disc could be disassembled the cost plenty of time during dismounting, defective with dismounting inconvenience causes to produce and shelves, and has had a strong impact on operating efficiency.Simultaneously, install that the junction deforms and fault such as absent-mindedness, reduced assembly precision between saw blade mounting disc and the mandrel, and then reduced the hot-metal sawing machine performance, influenced the hot-metal sawing machine work quality because frequent dismounting by force causes between saw blade mounting disc and the mandrel.
Summary of the invention
Technical problem to be solved by this invention is, in order to overcome above-mentioned the deficiencies in the prior art, and convenient disassembly and do not influence the saw arbor structure of hot sawing machine of hot-metal sawing machine performance when a kind of replacing second spring bearing is provided.
In order to solve the problems of the technologies described above, adopted following technical scheme among the present invention:
A kind of saw arbor structure of hot sawing machine, comprise the mandrel body, described mandrel body left end is used to install first spring bearing, right-hand member is used to install second spring bearing and saw blade mounting disc, middle for locating shaft shoulder section, its characteristics are that described location shaft shoulder section is that cylinder of socket forms the location shaft shoulder on the mandrel body, and the mandrel diameter at this sheathed place of cylinder is equal to or less than the second spring bearing place mandrel diameter.
More particularly, the present invention is on the basis of existing saw arbor structure of hot sawing machine, change to be made as and be set in the location shaft shoulder that forms on the mandrel body originally locating the positioning step shaft shoulder in the shaft shoulder section by a cylinder, the mandrel diameter at this sheathed place of cylinder is equal to or less than the second spring bearing place mandrel diameter, cylinder can adopt and intermittently cooperate or the less interference fit of the magnitude of interference, when dismantling like this, can keep the saw blade mounting disc motionless, and dismantle second spring bearing from left, because shaft coupling, the dismounting of first spring bearing and cylinder all is more prone to than the dismounting of saw blade mounting disc, so have the advantage of convenient disassembly, when installing simultaneously, second spring bearing is by saw blade mounting disc location, cylinder is by second spring bearing location, first spring bearing is by the cylinder location, with second spring bearing, cylinder, after first spring bearing all installs again, adopt shaft coupling that mandrel is connected with line shaft again.
In sum, adopt saw arbor structure of hot sawing machine of the present invention, when changing second spring bearing, have conveniently advantage of dismounting and change, saved a large amount of take-down times, improved production efficiency indirectly; Simultaneously, because dismounting and kept saw blade mounting disc integral body motionless when ressembling is that former assembling precision is constant so can guarantee saw blade mounting disc assembly precision, guaranteed that hot-metal sawing machine performance and work quality in follow-up use are unaffected.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
During concrete enforcement, as shown in Figure 1, a kind of saw arbor structure of hot sawing machine, comprise mandrel body 1, described mandrel body 1 left end is used to install first spring bearing 2, first spring bearing, 2 left ends are used to install shaft coupling, mandrel body 1 right-hand member is used to install second spring bearing 3 and saw blade mounting disc 4, fixedly mount saw blade in the saw blade mounting disc 4 again, be location shaft shoulder section in the middle of the mandrel body 1, described location shaft shoulder section is that cylinder of socket 5 forms the location shaft shoulder on the mandrel body 1, and the mandrel diameter at these cylinder 5 sheathed places equals second spring bearing 3 and first spring bearing, 2 place's mandrel diameters.Adopt matched in clearance between cylinder 5 and the mandrel body 1.
When being specially adapted to steel rolling mill's steel rolling, the present invention practices in the hot-metal sawing machine of special use.
