Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
The utility model provides a composite hammer head for a crusher, which is shown in figure 1-2; comprises a hammer seat 1 fixedly connected with a crusher; the hammer head 2 is a square block formed by sand mould pouring; a plurality of openings 21 are formed in the mounting surface of the hammer head 2, and straight thread sleeves 3 are fixedly arranged in the openings 21 through pouring; the straight thread sleeve 3 is internally provided with an internal thread in threaded connection with the bolt 4;
the straight thread sleeve 3 is integrally provided with a connecting part 31 with the opening 21, and the connecting part 31 is positioned in the opening 21 to fixedly connect the straight thread sleeve 3 with the hammer head 2.
In the above implementation, specifically, the straight threaded sleeve 3 is subjected to high-temperature tempering treatment after quenching, and then is tapped in the straight threaded sleeve 3 to form an internal thread, so that the straight threaded sleeve 3 is well matched with the toughness in strength, the strength is high, the hardness and the wear resistance can be improved, the tapping forming is facilitated, the number of the openings 21 and the number of the straight threaded sleeves 3 are two, and the symmetrical parts along the central axis of the hammer head 2 are at two ends; in addition, the straight thread sleeve 3 is integrally provided with a connecting part 31 with the opening 21, and the connecting part 31 is positioned in the opening 21, so that the straight thread sleeve 3 is fixedly connected with the hammer head 2, the separation between the straight thread sleeve 3 and the hammer head 2 composite structure can be effectively prevented, the connecting strength of the straight thread sleeve 3 is ensured, and the straight thread sleeve 3 has a good using effect; the installation mode of the bolt 4 is changed, after the fixed connection between the hammer seat 1 and the hammer head 2 is ensured, the bolt 4 is prevented from being directly impacted by materials through the connection mode of the rear bolt 4, the phenomenon that the bolt 4 is broken due to impact of crushed materials is avoided, even if the crushing working surface of the hammer head 2 is abraded, the bolt 4 is still in a normal connection state, the falling of the hammer head 2 is protected, and even if the hammer head 2 is replaced after being abraded, the bolt 4 is still recycled during equipment maintenance, so that the safety is greatly improved; reduce workman maintenance intensity, also ensured the high-efficient convenience that later stage tup 2 was with trading.
