Abstract
The utility model discloses a hammer, in particular a high-chromium cast hammer belonging to the technical field of manufacture of metallurgy production equipment and providing a high-chromium cast hammer which brings the convenience for processing a connecting hole and processing a connecting thread in the connecting hole. The hammer comprises a hammer body made of a high-chromium cast material and a connecting hole the inside of which is provided with a thread. The hammer also comprises a low-carbon steel block embedded on the hammer body, wherein the connecting hole is arranged in the low-carbon steel block.
Description
Technical field
The utility model relates to a kind of tup, especially relates to a kind of rich chromium cast iron tup, belongs to metallurgical production equipment manufacturing technology field.
Background technology
The rich chromium cast iron tup is the main wear-resisting workpiece of plate-hammer crusher, also is in the metallurgical production raw material set-up procedure, especially the critical component in the pulverizing production process of iron ore.Simultaneously, also abominable because of its working environment is so require it to have higher hardness and wearability.Because its material is a rich chromium cast iron, is the higher martensite of hardness+carbide tissue through its matrix after the heat treatment, can't process when connecting hole is bored at the back side with the processing connecting thread in the later stage, cause tup to scrap.
The utility model content
The utility model technical problem to be solved is: a kind of be convenient to process connecting hole and the rich chromium cast iron tup of being convenient to processing connecting thread in connecting hole are provided.
The technical scheme that adopts for solving the problems of the technologies described above is: a kind of rich chromium cast iron tup; Comprise tup body and the threaded connecting hole of machined processed by high chromium cast iron material; Also comprise the mild steel bloom that is embedded on the tup body, connecting hole is arranged on the mild steel bloom.
Further be, the mild steel bloom is the frustum structure, and its big end is positioned at the inside of tup body, and small end is positioned at the surface of tup body.
Further be that the mild steel bloom is embedded on the tup body through being cast into structure.
The beneficial effect of the utility model is: through inlaying a mild steel bloom on the tup body of processing at high chromium cast iron material, and connecting hole is arranged on the described mild steel bloom.Because the mild steel bloom is in the postorder heat treatment process; Its hardness can not increase; And the mild steel bloom has good machinability; Just process connecting hole above that and in connecting hole, process connecting thread, both reduced the scrappage of rich chromium cast iron tup body, improved the efficient of processing again in the process of processing connecting hole.
Description of drawings
Fig. 1 is the main cross-sectional schematic of a kind of rich chromium cast iron tup of the utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1 of the rich chromium cast iron tup of another kind of structure.
Be labeled as among the figure: tup body 1, connecting hole 2, mild steel bloom 3.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3 be a kind of rich chromium cast iron tup of being convenient to process connecting hole and being convenient to processing connecting thread in connecting hole that the utility model provides.Said tup comprises the tup body of being processed by high chromium cast iron material 1 and the threaded connecting hole 2 of machined, also comprises the mild steel bloom 3 that is embedded on the tup body, and connecting hole 2 is arranged on the mild steel bloom 3.Adopt the said mild steel bloom 3 of on the tup body 1 that high chromium cast iron material is processed, inlaying; And after connecting hole 2 is arranged on the structure on the described mild steel bloom 3; Because mild steel bloom 3 is in the postorder heat treatment process; Its hardness can not increase, and mild steel bloom 3 has good machinability, is convenient to process connecting hole 2 above that and processing connecting thread in connecting hole 2; Both reduced the scrappage of rich chromium cast iron tup body 1, improved the efficient of processing again in the process of processing connecting hole 2.
Be mounted on the rich chromium cast iron tup body 1 for the ease of mild steel bloom 3, make mosaic texture simpler simultaneously, mild steel bloom 3 is the frustum structure, and its big end is positioned at the inside of tup body 1, and small end is positioned at the surface of tup body 1.Like this, both made things convenient for mild steel bloom 3 to be mounted on the rich chromium cast iron tup body 1, and can guarantee in use again, mild steel bloom 3 can not come off from rich chromium cast iron tup body 1.Further, after inlaying completion mild steel bloom 3, remain an integral body in order to make rich chromium cast iron tup body 1, prolong its service life, mild steel bloom 3 is embedded on the tup body 1 through being cast into structure.Promptly before cast rich chromium cast iron tup body 1; Earlier that mild steel bloom 3 is pre-buried in the cast model; And then the structure of pouring into a mould; Be mounted in the rich chromium cast iron tup body 1 thereby both be convenient to mild steel bloom 3, and can guarantee that again rich chromium cast iron tup body 1 is after inlaying completion mild steel bloom 3, to remain an integral body, thereby effectively prolong the service life of rich chromium cast iron tup body 1.
