Abstract
The utility model relates to the technical field of rolling equipment, and in particular to a main transmission catcher of a rolling mill. The main transmission catcher comprises a cylindrical catcher main body, wherein an accommodation groove with a limiting surface is formed in the middle axis direction of an end face of the catcher main body; a through hole communicated with the accommodation groove is formed in the other end face; the size of the through hole is smaller than that of the accommodation groove; a hard alloy overlaying layer is arranged on the inner wall of the accommodation groove; a quench hardening layer is further arranged between the hard alloy overlaying layer and the inner wall of the accommodation groove. As the hard alloy overlaying layer and the quench hardening layer are arranged on the inner wall of the accommodation groove, the strength of the inner wall of the accommodation groove can be strengthened; even after use for a long time, the inner wall of the accommodation groove is a little in abrasion, can be continued using, and achieves long service life.
Description
Technical field
The utility model relates to rolling equipment technical field, is specifically related to a kind of Main Drive of Rolling Mill catcher.
Background technology
Metallurgy rolling mill cross bag assembly comprise cross packaging join, take over and between three kinds of parts of chain connecting bolt form.Generally use at present on thick, the finishing mill of all kinds of large-scale continuous casting continuous rolling production lines, as a topmost portion cover on the cross universal coupling of active force transmission, play link spindle and roll, the effect of transmission gear distribution box driving force, because roller palm is all through cure process, and the torque ratio transmitting when rolling is larger, so the failure mode of this product maximum is exactly inner chamber wearing and tearing.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of Main Drive of Rolling Mill catcher of reasonable in design, and it has abrasion-proof structure, long service life.
Realize the technical solution of the utility model as follows:
A kind of Main Drive of Rolling Mill catcher, comprise columniform catcher body, on one end face middle part axis direction of described catcher body, offer the storage tank with confined planes, other end offers the through hole being communicated with storage tank, the size of this through hole is less than the size of storage tank, described storage tank inwall is provided with weld-deposited cladding, between weld-deposited cladding and storage tank inwall, is also provided with laser quenching hardened layer.
Adopted such scheme, at storage tank inwall, weld-deposited cladding, laser quenching hardened layer have been set, it can strengthen the intensity of storage tank inwall, and after using even long-time, the inner wall abrasion of storage tank is little, also can continue to use long service life.
Further, the shape of cross section of described storage tank is the rectangle that two ends adopt arc-shaped transition.
Further, the end face that described catcher body offers through hole extends size and is less than the assembling end of taking over body.
Further, the thickness of described weld-deposited cladding, laser quenching hardened layer is 0.5cm-3cm.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to schematic diagram;
Fig. 3 is that the B-B of Fig. 2 is to schematic diagram;
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Referring to Fig. 1,2,3, a kind of Main Drive of Rolling Mill catcher, comprise columniform catcher body 1, on one end face middle part axis direction of catcher body, offer the storage tank 2 with confined planes, other end offers the through hole 3 being communicated with storage tank, the size of this through hole is less than the size of storage tank, and storage tank inwall is provided with weld-deposited cladding 4, between weld-deposited cladding and storage tank inwall, is also provided with laser quenching hardened layer 5.In concrete enforcement, the shape of cross section of storage tank 2 is the rectangle that two ends adopt arc-shaped transition.The end face that catcher body offers through hole extends size and is less than the assembling end 6 of taking over body.The thickness of weld-deposited cladding, laser quenching hardened layer is 0.5cm-3cm.Main transmission catcher adopts hardening and tempering method, improves overall mechanical property, and laser quenching hardened layer adopts integral quenching mode to form, and weld-deposited cladding adopts laser stacks welding method to form.Adopt integral quenching to add surface overlaying method, both avoided the cool time to grow and the cracking risk of generation, reduced again overlay cladding thickness, reduced greatly cost of manufacture.
Claims (4)
