Abstract
A novel shield constructs quick-witted hobbing cutter ring, it relates to shield and constructs quick-witted cutter technical field. It contains the cutter ring body, the cutter ring body includes: the outer ring is arranged on the outer side of the inner ring and integrally formed with the inner ring, and is characterized in that one side, far away from the inner ring, of the outer ring is provided with a protruding sharp surface. The thickness of the cutter ring body is gradually reduced from the inner ring to the outer ring. An arc-shaped transition surface is arranged between the inner ring and the outer ring on the cutter ring body. The inner ring and the outer ring are both made of HRC60-62 steel products. According to the technical scheme, the protruding sharp surface is arranged on one side, far away from the inner ring, of the outer ring, so that the area is reduced, the pressure intensity is enhanced, the sharpness of the cutter ring is increased, and the cutting is facilitated. The inner ring and the outer ring are both made of HRC60-62 steel products. The wear resistance and the toughness of the cutter ring body are ensured.
Description
Technical Field
The utility model relates to a shield constructs quick-witted cutter technical field, concretely relates to novel shield constructs quick-witted hobbing cutter ring.
Background
At present, the cutting part of the cutter ring of the shield machine is generally a plane or an arc surface, the cutting part is in contact with an external object to be cut, such as a granite layer, the contact area is large, and when the cutter ring meets a hard or irregular rock stratum under the current situation during the working period of the shield machine, the action resistance of the cutter ring is large, so that the cutter ring is easy to wear quickly. Therefore, improvements are desired.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art's defect and not enough, provide a novel shield constructs quick-witted hobbing cutter ring, set up outstanding sharp face through keeping away from inner circle one side on outer circle to realize reducing the area, strengthen pressure, increase the sharpness of cutter ring, be convenient for cut. The inner ring and the outer ring are both made of HRC60-62 steel products. The wear resistance and the toughness of the cutter ring body are ensured.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a novel shield constructs quick-witted hobbing cutter ring, includes the cutter ring body, the cutter ring body includes: the outer ring is arranged on one side, far away from the inner ring, of the outer ring and is provided with a protruding sharp surface.
The thickness of the cutter ring body is gradually reduced from the inner ring to the outer ring.
An arc-shaped transition surface is arranged between the inner ring and the outer ring on the cutter ring body.
The inner ring and the outer ring are both made of HRC60-62 steel products.
After the technical scheme is adopted, the utility model discloses beneficial effect does: one side of the outer ring, which is far away from the inner ring, is provided with a protruding sharp surface, so that the area is reduced, the pressure intensity is enhanced, the sharpness of the cutter ring is increased, and the cutting is facilitated. The inner ring and the outer ring are both made of HRC60-62 steel products. The wear resistance and the toughness of the cutter ring body are ensured.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
Fig. 1 is a schematic structural diagram of the present invention.
Description of reference numerals: 1. a cutter ring body; 11. an inner ring; 12. an outer ring; 121. sharp surface; 111. an arc-shaped transition surface.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment as required without making a contribution, but all the embodiments are protected by the patent law within the scope of the claims of the present invention.
The embodiment relates to a novel shield constructs quick-witted hobbing cutter ring, as shown in fig. 1, including cutter ring body 1, cutter ring body 1 includes: the inner ring 11 and the outer ring 12 are arranged outside the inner ring 11 and integrally formed with the inner ring 11, and a protruding sharp surface 121 is arranged on one side of the outer ring 12 far away from the inner ring 11. The contact area of the sharp surface 121 protruding from the outer ring 12 and the external rock formation is reduced, so that the pressure is increased, the rock formation is cut conveniently, and the abrasion of the outer ring 12 is reduced. In the present embodiment, the inner ring 11 and the outer ring 12 are both made of steel having a hardness of HRC 60-62. The wear resistance and the toughness of the cutter ring body 1 are ensured.
Preferably, the thickness of the cutter ring body 1 is gradually reduced from the inner ring 11 to the outer ring 12. In the present embodiment, an arc-shaped transition surface 111 is provided on the cutter ring body 1 between the inner ring 11 and the outer ring 12. The manufacturing cost of the cutter ring body 1 is reduced, and the cutting of the hob cutter ring of the shield machine is further facilitated.
The working principle of the utility model is as follows: the protruding sharp surface 121 is arranged on one side, far away from the inner ring 11, of the outer ring 12, so that the area is reduced, the pressure intensity is enhanced, the sharpness of the cutter ring is increased, and the cutting is facilitated. The inner ring 11 and the outer ring 12 are both made of HRC60-62 steel products. The wear resistance and the toughness of the cutter ring body 1 are ensured.
The above description is only for the purpose of illustration and not limitation, and other modifications or equivalent replacements made by those skilled in the art to the technical solution of the present invention should be covered by the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
