The wearability of material can be improved, so as to improve the service life of tup, high tenacity can prevent tup from going out in use
Now unexpected fracture, causes security incident.It is general more difficult using single material while meet the requirement of this hardness and toughness.For
Solves this problem, typically using Double-metal composite hammer, the hammer tip of tup is typically using the material of high-wear resistance as high
Chrome cast iron, hammer handle material is using toughness material such as carbon steel etc., and in this case, hammer tip has good wearability, hammer handle tool
There is higher toughness, composite request of the tup to hardness and toughness can be met.But this tup is sent out in use
It is existing one more serious the problem of：Because hammer handle is completely using relatively low carbon steel of hardness and anti-wear performance etc., its is wear-resisting
Property is excessively poor.In use, although the broken of material is mainly completed by the hammer tip of tup, hammer handle also will be by material
Wash away and abrasive action, the abrasive action being subject to closer to the hammer handle of hammer tip is more serious, so, tup work a period of time
Afterwards, hammer handle will be subject to severe abrasion, is tapered, until the impulsive force of tup finally can not be born and be broken completely, causes
, there is serious security incident in the unexpected failure of tup.It must be solved for this using new technical scheme.
The content of the invention
The purpose of this utility model is just to provide a kind of hammer handle full protection castingin Double-metal composite hammer, and it can effectively be solved
Problem existing for certainly existing metal composite tup.
What the purpose of this utility model was realized in：A kind of hammer handle full protection castingin bimetallic for broken material is answered
Tup is closed, comprising hammer tip and hammer handle, hammer tip coats the head of hammer handle, and hammer handle four sides is complete from hammer tip root to hammer handle mounting hole root
Portion is coated with the wear-resistant protective layer of material identical with hammer tip, and the wear-resistant protective layer is simultaneously connected as one in hammer tip root and hammer tip
Body.
The thickness of the wear-resistant protective layer is gradually reduced from hammer tip root to hammer handle mounting hole root direction.
Hammer handle is provided with by the position that hammer tip coats and mechanically connects hole.
Due to tup in the course of the work, hammer handle from hammer tip root to hammer handle mounting hole root all exposed to broken thing
Expect in environment, acted on by the impact wear of broken material, therefore, hammer handle four sides is complete from hammer tip root to hammer handle mounting hole root
Portion is coated with the wear-resistant protective layer of material identical with hammer tip, can effectively improve all portions of castingin Double-metal composite hammer hammer handle
The anti-wear performance of position, prevent its abrasion by broken material and it is caused attenuate after the possibility that is broken, improve the synthesis of tup
Service life.For described wear-resistant protective layer in hammer tip root with connecting as one, the connection for adding protective layer is reliable on hammer handle
Property, for preventing coming off for wear-resistant protective layer from having good protective effect.
Because closer to hammer tip, the material impact abrasion suffered by hammer handle is more serious, therefore anti-wear performance should be more preferable.For
This, in the part of hammer tip root, the thickness of wear-resistant protective layer makes most thick.Further away from hammer tip, impact grinding of the material to hammer handle
The degree of damage is lower, therefore the requirement to anti-wear performance is lower, for this from hammer tip to hammer handle direction hammer handle outside coated
The thickness of wear-resistant protective layer is gradually reduced, and so can both effectively reduce the usage amount of tup high-abrasive material, reduces cost, together
When nor affect on protective effect to hammer handle.
The wear-resistant protective layer that is connected as one with hammer tip again while covers full hammer handle, adds the company between hammer tip and hammer handle
Relay, connection reliability between the two can be further improved, to preventing coming off for hammer tip from playing further prevention effect.
Because tup is produced using imbedding process, thus the reliability connected between hammer tip and hammer handle for tup just
Often work has very important effect.Connecting hole is set at the hammer handle position coated by hammer tip, hammer tip high-abrasive material is in tup
Entered in production process in connecting hole, play a part of mechanical connection, strengthen the reliability connected between hammer handle and hammer tip,
To preventing that it is good that coming off in the hammer tip course of work from playing the role of, the reliability that product uses is improved.

Tup is produced using castingin double-metal composite casting process.Hammer handle is cast in advance using carbon structural steel material
Make, clear up and process after the completion of casting, then put it into sand mold, carry out secondary castingin cast, pour into a mould hammer tip rich chromium cast iron material
Matter.Rich chromium cast iron forms hammer tip after cast, and simultaneously coats hammer handle completely, is formed from hammer tip root to hammer handle mounting hole root
The wear-resistant protective layer that direction is gradually thinned.When tup carries out crushing operation, it is arranged on by mounting hole on disintegrating machine, disintegrating machine band
Dynamic tup rotates at a high speed, impacts the material entered in disintegrating machine, material is crushed.In the process, because hammer tip rotates speed
Highest, while the position most directly contacted with material in disintegrating machine are spent, therefore the broken of ore is carried out mainly by hammer tip, hammer
The abrasion at end also most serious.At the same time, inevitably there is partial material to impact on hammer handle in disintegrating machine, produce hammer handle
Raw certain abrasion, but be all coated with and hammer tip identical High Hardness High Chromium cast iron wear-resistant protection because hammer handle four sides is outside
Layer, therefore can effectively protect the carbon structural steels hammer handle of soft not frayed.With the increase apart from hammer tip distance, due to
The speed of hammer handle corresponding site gradually reduces, therefore the impact wear of suffered material is also smaller, using relatively thin wear-resistant protective layer
It can reach and effectively protect.Wear-resistant protective layer thickness on hammer handle gradually reduces from hammer tip root to hammer handle mounting hole root,
The service life at each position of hammer handle can both matched substantially, has reached basically identical with the tup hammer tip life-span, can save again
The valuable hammer tip high-abrasive material in part, so that the economic benefit that tup uses reaches maximum.Hammer tip material is to hammer handle simultaneously
Full cladding, can further improve connection function between the two, prevent hammer tip coming off in use.
The mechanical connection hole pre-set on hammer handle is full of hammer tip metal i.e. rich chromium cast iron during the secondary castingin of tup,
Hammer tip is connected on hammer handle by equivalent to one mechanical pin, is added the reliability connected between the two, is further ensured
