Embodiment Construction

[0018] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0019] The embodiment of the present invention provides a method for taking out a cutter ring of a waste hob, comprising the following steps:

[0020] Step 1. Preparing and cleaning the waste hob;

[0021] Step 2. Move the waste hob to the workbench, and fix the waste hob on the workbench according to the set direction;

[0022] Step 3, using induction heating to heat the waste hob, and separating the knife ring and the knife body of the waste hob.

[0023] In the embodiment of the present invention, the waste hob is heated by induction heating. Since the thermal expansion properties of the cutter ring and the cutter body are different, the cutter ring and the cutter body can be separated dur...

Abstract

The invention provides a method for taking out a cutter ring of a waste hob, which includes the following steps: step 1, performing a preparation and cleaning operation on the waste hob; The setting direction is fixed on the worktable; Step 3, use the induction heating method to heat the waste hob, and separate the cutter ring of the waste hob from the cutter body. The beneficial effect of the present invention is that in the embodiment of the present invention, the waste hob is heated by induction heating. Since the thermal expansion performance of the cutter ring and the cutter body is different, the cutter ring and the cutter body can be separated during the induction heating process, avoiding the traditional The cutter ring can be damaged by the method, and the undamaged cutter ring can be remanufactured in the later stage, which can achieve the purpose of saving cost.

Description

technical field [0001] The invention relates to a method for taking out a cutter ring of a waste hob. Background technique [0002] At present, tunnel boring shield machines and hard rock TBM tunneling machines mainly rely on disc-shaped hobs to squeeze rocks to crush rock mass. As a vulnerable part in direct contact with rocks, hobs need to be inspected, repaired and replaced frequently. In the traditional process, the wear amount of the cutter ring of the hob is checked first. When the wear amount of the cutter ring reaches the specified value, the hob is disassembled from the cutter head and transported from the tunnel face to the tool repair room outside the tunnel. . Since the cutter ring and the cutter body are connected by an interference fit, and the interference is relatively large, a cutting machine is generally used to cut off the worn cutter ring and install a new cutter ring. The cut cutter rings cannot be reused, and the waste cutter rings are usually discard...
