Abstract
The present invention relates to a kind of circular cone sand making machines to be both able to satisfy the wear-resisting requirement being crushed to rubble during sand processed, it is able to satisfy the circular cone sand making machine crushing wall being made of potassium steel and high-carbon chromium steel and production method of the wear-resisting requirement for rolling sand processed again, crushing wall top is potassium steel, crushing wall lower part is high-carbon chromium steel.Advantage: first is that fundamentally solving homogenous material crushing wall during sand processed, since the building stones of different size are different to the abrasion loss of crushing wall, caused crushing wall Upper wear is small, sand chamber shape formation groove processed is rolled in lower part caused by wearing greatly and the critical defect without legal system sand；Second is that the potassium steel on crushing wall top abrasion loss caused by broken building stones and the abrasion loss that sand chamber processed is rolled in high-carbon chromium steel crushing wall lower part are relatively uniform.
Description
Technical field
The present invention relates to a kind of circular cone sand making machines to be not only able to satisfy the wear-resisting requirement being crushed to rubble, but also energy during sand processed
Meet the circular cone sand making machine crushing wall being made of potassium steel and high-carbon chromium steel and production method for rolling the wear-resisting requirement of sand processed, belongs to
Circular cone sand making machine component assembly manufacturing field.
Background technique
CN102294280A, title " cone sand making machine Special high-chromium crushing wall and assembly ", it includes that crushing wall is total
At the crushing wall material is high chromium white antifriction cast iron, and chromium content is greater than or equal to 9%, is equal to or less than 32%.Advantage:
First is that crushing wall wear-resisting property greatly improves, wearability is 5 times or so of current potassium steel crushing wall, and not only service life is big
It is big to extend, and the use cost of user is greatly reduced；Resist second is that realizing and improving high chromium white with the structure of physics
The impact resistance for grinding cast iron crushing wall, has effectively been sustained impact force suffered by high chromium white antifriction cast iron crushing wall, solves
High chromium white antifriction cast iron crushing wall is hit the defect of cracky.But since circular cone sand making machine is during sand processed
From the two different working conditions of sand system processed that are crushed to of building stones, crushing wall top is for being crushed building stones, and building stones are to crushing wall
What top was formed is that impact load and contact squeeze, and what building stones and crushing wall formed is not know, be not all of and connect
The impact extruded rubble cooperation of touching property, thus it is relatively small to the state of wear on crushing wall top；And crushing wall lower part is the system of rolling
Sand portion, full contact that broken small building stones are formed with crushing wall, plyability roll, between crushing wall and rolled mortar wall
Under the small strength in crushing wall and crushing wall of broken gravelstone rolls, sandstone is very tight to the abrasion of crushing wall (also including rolling mortar to ward off)
Weight.If using homogenous material production crushing wall, either manganese steel or rich chromium cast iron is adopted, due to the building stones pair of different size
The abrasion loss of crushing wall is different, as a result causes that crushing wall Upper wear is small, middle part abrasion opposite upper parts are small and lower part wears to be formed
The situation of groove, causes crushing wall to wear, and blanking velocity is slow, and machine electric current increases, and instruction replacement crushing wall, crushing wall uses
Period is short.
Summary of the invention
Purpose of design: avoiding the shortcoming in background technique, and designing a kind of circular cone sand making machine can during sand processed
Meet the wear-resisting requirement being crushed to rubble, and is able to satisfy being made of potassium steel and high-carbon chromium steel for the wear-resisting requirement that rolls sand processed
Circular cone sand making machine crushing wall and production method.
Design scheme: in order to realize above-mentioned purpose of design.The present invention is in structure design: 1, crushing wall top is Gao Meng
Steel, the design that crushing wall lower part is high-carbon chromium steel, are one of technical characteristics of the invention.The purpose of this design is: Gao Meng
Steel is resistant to one of the optimal selection in the wear-resistant materials such as thump, the abrasion of big pressure material, it not only has other wear-resisting materials
Expect incomparable Work Hardening Characteristic, and in greater impact load or under the action of compared with large contacting stress, potassium steel
Surface layer generates processing hardening, and surface hardness promotes rapidly HRC45 or more by HRC17--21, and with cementation zone
It gradually wearing out, new work hardening layer can be formed successively, thus while generating endlessly high abrasion superficial layer, and
Potassium steel internal layer austenite still keeps good impact flexibility.The present invention is exactly to utilize this characteristic of potassium steel, by crushing wall
Top (or middle part and top) use potassium steel, since crushing wall top is for being crushed building stones, building stones are to crushing wall top
What is formed is precisely impact load, it is thus possible to make crushing wall case-hardening, hardness is promoted rapidly, meets crushing wall top
Hardness requirement and wear-resisting requirement to rubble；And the carbon containing Wc of high-carbon chromium steel is 1% or so, chrome content Wcr is 1.5% or so, and is contained
There is the hypereutectoid steel of a small amount of manganese, element silicon.Chromium can improve heat treatment performance, improve harden ability, structural homogenity, tempering surely
It is qualitative, and the rustless property and grinding performance of steel can be improved, hardness reaches HRC63 ± 3, has excellent wearability, meets
The wear-resisting requirement of sand processed is rolled, abrasion loss is significantly less than potassium steel.2, crushing wall top and crushing wall lower part are in embossed card
Engagement is connect to be the second technical feature of the present invention.The purpose of this design is: the convex-concave on crushing wall top is connected to broken
In the concaveconvex structure of wall lower part, crushing wall bottom synchronous liter is able to drive when crushing wall top is risen under the effect of external force
It rises, to reach the size for facilitating Longkou (rolling chamber) between adjustment crushing wall and crushing wall.
Technical solution 1: a kind of circular cone sand making machine crushing wall being made of potassium steel and high-carbon chromium steel, crushing wall top are height

Compared with the background technology, the present invention, first is that fundamentally solving homogenous material crushing wall during sand processed, by
Different to the abrasion loss of crushing wall in the building stones of different size, caused crushing wall Upper wear is small, lower part abrasion is big and leads
The sand chamber shape processed of rolling caused forms groove and the critical defect without legal system sand；Second is that the potassium steel on crushing wall top is in broken building stones
Generated abrasion loss and the abrasion loss that sand chamber processed is rolled in high-carbon chromium steel crushing wall lower part are relatively uniform, thus fundamentally solve
Sand chamber processed is rolled during stone roller sand in the crushing wall lower part of homogenous material, since abrasion loss is greater than crushing wall Upper wear amount
The situation of caused groove, not only greatly extends the service life of crushing wall, but also greatly reduces the system of crushing wall
While causing this and use cost, sand cost processed is reduced.
