Technical Field
[0001] The utility model relates to the technical field of alloy hammer heads, in particular to a high-strength welded alloy hammer head. Background Art
[0002] Alloy hammer heads are used as hammer heads for crushing in crushers. In the existing technology, they are all formed in one piece. However, a lot of expensive metals need to be added to the alloy hammer heads. Therefore, the alloy hammer heads can be spliced by welding to save costs.
[0003] However, the use of the alloy hammer head in the crusher determines that it needs to meet sufficient connection strength during welding. The existing welding method usually adopts the method of directly welding the alloy hammer head to the connecting part. Such welding strength is low and cannot meet the use requirements of the alloy hammer head. Utility Model Content
[0004] The purpose of the present invention is to provide a high-strength welded alloy hammer head to solve the problem in the above background technology that the existing welding method has low strength and cannot meet the use requirements of the alloy hammer head.

[0006] Preferably, a buffer plate is provided on the top of the connecting frame, and the buffer plate is fixedly connected to the connecting frame.
[0007] Preferably, there are two strengthening welding strips, one side of which is fixedly welded to the hammer body, and the other side of which is fixedly welded to the connecting frame.
[0008] Preferably, the hammer body is tightly fitted to the inner wall of the connecting frame.
[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0010] The high-strength welded alloy hammer head of the utility model welds the fillet welding rod between the hammer head body and the connecting frame into a concave shape, and fuses with the adjacent hammer head body and connecting frame to avoid stress concentration at the weld between the hammer head body and the connecting frame;
[0011] The hammer body is welded continuously by using fillet welding rods and strengthening welding rods, which reduces the tendency of cracks at the joints, improves the quality of welding, and thus improves the welding strength. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] See also Figure 1-4, a high-strength welded alloy hammer head, comprising a mounting frame 1, a connecting frame 2 and a hammer head body 3, a mounting hole is provided inside the mounting frame 1, the bottom end of the mounting frame 1 is fixedly connected to the connecting frame 2, the bottom of the connecting frame 2 is provided with a hammer head body 3, a pre-set weld 21 is provided on the outside of the connecting frame 2, the pre-set weld 21 surrounds the outer surface of the connecting frame 2 and passes through the connecting frame 2, a fillet welding rod 4 is provided between the bottom of the connecting frame 2 and the hammer head body 3, the cross-section shape of the fillet welding rod 4 is concave, and the minimum radius of the fillet welding rod 4 is the connecting Fifty percent of the wall thickness of the frame 2 is used to avoid stress concentration at the welding point between the connecting frame 2 and the hammer body 3. A strengthening welding strip 31 is also provided inside the preset weld 21. The cross-sectional shape of the strengthening welding strip 31 is also concave. The cross-sectional shape of the fillet weld 4 and the strengthening welding strip 31 is ground into a concave surface by grinding, so that the force direction of the weld joint is the same as the direction of the grinding lines, and the arrangement of the welds is symmetrical, which reduces the possibility of welding deformation, effectively avoids the stress concentration point, and improves the welding strength.
