Abstract

The invention discloses a pinch roll. The pinch roll comprises a roll body and roll shafts, wherein the roll body is cylindrical; the roll shafts extend along the two ends in the longitudinal direction of the roll body; the roll body is subjected to thermal refining; and the Rockwell hardness range HRC on the surface of the roll body is 60 to 62. By performing the thermal refining on the roll body of the pinch roll, the Rockwell hardness range HRC on the surface of the roll body reaches 60 to 62; the requirements of a plurality of production places can be met; and moreover, the cost is lower relative to the method of increasing the hardness of the roll body by adding an alloy.

Description

Wherein, said roll body is through modifier treatment, and the HRc scope on said roll body surface is HRC60 ~ 62.
As further improvement of the present invention, handle through electro-high-frequency hardening on said roll body surface.
As further improvement of the present invention, said roll shaft comprises first roll shaft that is arranged at said roll body one end and second roll shaft that is arranged at the said roll body other end, and the length of said second roll shaft is greater than the length of said first roll shaft.
As further improvement of the present invention, said first roll shaft comprises that the length of said first is 45 millimeters from the first of said roll body one end extension and the second portion that extends from said first, and the length of said second portion is 50 millimeters.
As further improvement of the present invention, the diameter of said first is greater than the diameter of said second portion.
As further improvement of the present invention, said second roll shaft comprises from the third part of said roll body other end extension, from the 4th part of said third part extension and the 5th part of extending from said the 4th part.
As further improvement of the present invention, the diameter of said third part is greater than said tetrameric diameter, and said tetrameric diameter is greater than the diameter of said the 5th part.
As further improvement of the present invention, the length of said third part is 45 millimeters, and said tetrameric length is 90 millimeters, and the length of said the 5th part is 85 millimeters.
As further improvement of the present invention, said the 5th part is provided with slug hole.
As further improvement of the present invention, said roll body is 850 millimeters along the length of longitudinally.
Compared with prior art, the present invention make the HRc scope on roll body surface reach HRC60 ~ 62, and cost is lower through carrying out modifier treatment at the roll body to pinch roll.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing relevant of the present invention in describing below only is some embodiments of the present invention, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of pinch roll one embodiment of the present invention.
The specific embodiment
Below will combine the specific embodiment shown in the drawings to describe the present invention.But these embodiments do not limit the present invention, and the conversion on the structure that those of ordinary skill in the art makes according to these embodiments, method or the function all is included in protection scope of the present invention.
Join Fig. 1, introduce a specific embodiment of pinch roll 10 of the present invention.This pinch roll 10 comprises roll body 11 and roll shaft.
Roll body 11 roughly is cylindrical shape, and roll shaft extends along the two ends of roll body 11 longitudinallies, is used for being connected with external mechanical part.
In this embodiment, roll body 11 is through modifier treatment, and the HRc scope on roll body 11 surfaces is HRC60 ~ 62.So-called modifier treatment is promptly quenched and the comprehensive Technology for Heating Processing of high temperature tempering, and it can make roll body 11 intensity, plasticity and toughness all be highly improved so that the performance of the material of roll body 11 is adjusted significantly, and, do not increase extra cost.
As preferred embodiment, handle through electro-high-frequency hardening on roll body 11 surfaces, and it can further improve the surface quality of roll body 11, promotes the durability of pinch roll 10.
Roll shaft comprises first roll shaft 12 that is arranged at roll body 11 1 ends and second roll shaft 13 that is arranged at roll body 11 other ends, and wherein, the length of second roll shaft 13 is greater than the length of first roll shaft 12.
Distinguishingly; First roll shaft 12 comprises from first 121 that said roll body 11 1 ends extend and the second portion 122 that extends from said first 121; The length of said first 121 is 45 millimeters; The length of said second portion 122 is 50 millimeters, and the diameter of first 121 is greater than the diameter of second portion 122.
Similarly; Second roll shaft 13 comprises that the length of said third part 131 is 45 millimeters from the third part 131 of roll body 11 other ends extension, from the 4th part 132 of third part 131 extensions and the 5th part 133 of extending from the 4th part 132, and the length of the 4th part 132 is 90 millimeters; The length of the 5th part 133 is 85 millimeters; And the diameter of third part 131 is greater than the diameter of the 4th part 132, and the diameter of the 4th part 132 is greater than the diameter of said the 5th part 133.
This is because roll shaft normally is used for being connected with external mechanics, so need a less dimensional characteristic.But if fruit directly is set to less diameter with roll shaft, then can cause between roll shaft and the roll body 11 bonded assembly unreliable easily, influence production.Through the roll shaft of this diameter that successively decreases one by one is set, can guarantee the Joint strenght of roll shaft and roll body 11 effectively.
As preferred embodiment, the 5th part 133 is provided with slug hole 14, and this slug hole 14 can reduce the weight of pinch roll 10 effectively, and helps the control of enterprise production cost.
Distinguishingly, in above-mentioned embodiment, roll body 11 is 850 millimeters along the length of longitudinally.
The present invention is through above-mentioned embodiment; Have following beneficial effect: the roll body 11 through to pinch roll 10 carries out modifier treatment; Make pinch roll 10 roll bodies 11 surface rockwell hardnesses reach HRC60 ~ 62; Can satisfy the needs of multiple production occasion, and increase the method for roll body 11 hardness with respect to adding alloy, cost is lower.
Be to be understood that; Though this specification sheets is described according to embodiment; But be not that each embodiment only comprises an independently technical scheme, this narrating mode of specification sheets only is for clarity sake, and those skilled in the art should make specification sheets as a whole; Technical scheme in each embodiment also can form other embodiments that it will be appreciated by those skilled in the art that through appropriate combination.
The listed a series of detailed description of preceding text only is specifying to feasibility embodiment of the present invention; They are not in order to restriction protection scope of the present invention, allly do not break away from equivalent embodiment or the change that skill of the present invention spirit done and all should be included within protection scope of the present invention.
