Abstract
The utility model provides a hammer head which is composed of a hammer body, the hammer head and a pin shaft. A hammer handle at one end of the hammer head is inserted into a groove of the hammer body, and is fixedly locked by the pin shaft penetrating through the hammer body, the hammer handle, the hammer body and an elastic retainer ring. The hammer head has the following characteristics: an entire rotor can be repeatedly used; the disassembling, installing and replacing are flexible; the production technique is advanced, the finished product rate is high, the production cost is low, and the economic benefit is obvious.
Description
Technical field: the utility model relates to employed a kind of tup in metallurgical and mining machinery, the crushing mechanism field.
Background technology: the material that is used at present to make grinder hammerhead both at home and abroad mainly is three kinds of potassium steel, low-alloy steel and rich chromium cast irons.Potassium steel has processing hardening properties.Yet, the potassium steel tup is in actual use because the impulsive force that is subjected to is limited, in being generally, low impulsive force, so can not highly be hardened in the tup surface, case hardness after the work hardening causes potassium steel tup wearability relatively poor through being everlasting more than the HB400.Tup adopts the Contiuum type tup in addition, is installed in respectively on the crusher rotor, and major defect is easy to wear, and easy fracture is changed inconvenience, and Master Cost is crossed high shortcoming.If a tup fracture is arranged on the rotor, whole rotor is just scrapped, and the grating in the hammer-crusher just needs all to change.
Summary of the invention: the purpose of this utility model will provide a kind of tup exactly, and it can overcome the existing problem of present grinder hammerhead.The purpose of this utility model is achieved in that a kind of tup, is made up of hammer body, tup, bearing pin, it is characterized in that: an end hammer handle of tup is inserted in the groove of hammer body setting, and passes hammer body, hammer handle, hammer body, circlip fixing and locking by bearing pin.The whole rotor of the utility model is reusable, removes and installs to change flexibly, and production technology advanced person, yield rate height, production cost is low, remarkable in economical benefits.
Description of drawings:
Fig. 1 is the utility model structural representation;
1. tup, 2. hammer body, 3. bearing pin, 4. circlip.
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;
A kind of tup is made up of hammer body 2, tup 1, bearing pin 3, it is characterized in that: an end hammer handle of tup 1 is inserted in the groove of hammer body 2 settings, and passes hammer body 2, hammer handle, hammer body 2, circlip 4 fixing and lockings by bearing pin 3.During concrete enforcement, tup is made by wearing composite material, and hammer body is made by the Aldecor material, has improved the abrasion hardness and the toughness of tup.Adopt and divide body structure that the other end hammer handle of tup is inserted in the groove of hammer body setting.When need changing if any wearing and tearing on the rotor, only need spend 10 to 15 minutes bearing pin is extracted out when shut down maintenance, more renew the tup use of just can starting shooting, the unit replacing time can shorten 10-15 hour.Whole rotor is reusable, has prolonged the service life of equipment.Remove and install and change flexibly, production technology advanced person, yield rate height, production cost is low, remarkable in economical benefits.
