Abstract

The utility model relates to a crusher hammer with a groove-shaped notch at the lower portion. The groove-shaped notch is arranged in the middle of the lower portion of the hammer, and the direction of the groove-shaped notch is parallel to crushing faces of materials on two sides. The section of the notch is in a trapezoid shape or a reversed trapezoid shape, and can be in an arc shape or a triangular shape. The groove-shaped notch is arranged at the lower portion of the hammer so that consumption of high chromium alloy cast iron is reduced and manufacture cost of the hammer is reduced. The crushing faces of the effective materials of the hammer are laterally symmetrical so that when the crushing face of the materials on one side of the hammer is abraded, the hammer can be overturned and the crushing face of the materials on the other side of the hammer can be used. Therefore, comprehensive benefits of crushed materials of users are improved.

Description

The bottom is provided with the grinder hammerhead of flute profile breach

Technical field

The utility model relates to a kind of grinder hammerhead, and especially a kind of bottom is provided with the grinder hammerhead of flute profile breach.

Background technology

Tup is the critical component of disintegrating machine, also is the parts of the easiest wearing and tearing, and the quality of the manufactured materials of tup, manufacture technology and structure thereof directly influences the operational efficiency and the operating cost of disintegrating machine.Therefore the structure of tup has become the technology competition point of disintegrating machine with service life.As everybody knows, disintegrating machine is to utilize the tup of rotation at a high speed and the material that falls from charge door to collide, with the material fragmentation.Therefore, require excellent mechanical performance to be arranged with the tup of material collision.For this reason, people adopt the high-chromium alloy that contains chemical elements such as Cr, Ti, Cu, Ni, Mo, Mn to cast tup, improve its hardness, toughness and wearability, prolong its service life.Higher because of the high-chromium alloy cast-iron price, it is unreasonable to add the hammehead structure design, though cause the life-span of tup to obtain prolongation, the broken quantity of material increases to some extent, and broken cost up has directly influenced the comprehensive benefit of material fragmentation.

Summary of the invention

The utility model is at the deficiencies in the prior art, provide a kind of bottom to be provided with the grinder hammerhead of flute profile breach, its manufacturing not only simple in structure, easy, have good hardness, toughness and wearability, and can save the more expensive high-chromium alloy cast-iron of price, reduce the manufacturing cost of tup, improve broken benefit.

The purpose of this utility model is achieved in that the bottom of being made up of hammer handle, tup is provided with the grinder hammerhead of flute profile breach, and its flute profile breach is located at the middle part of tup bottom, and the trend of flute profile breach parallels with the both sides material plane of disruption; The cross sectional shape of its breach is trapezoidal or trapezoidal, also can be arc or triangle.

The utility model has obviously reduced the consumption of expensive high-chromium alloy cast-iron owing to be provided with the flute profile breach in the bottom of tup during manufacturing, the manufacturing cost of tup is reduced, and the comprehensive benefit of material fragmentation is improved.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is a front view of the present utility model;

Fig. 2 is the left view of Fig. 1.

Among the figure: 1, hammer handle; 2, prefabricated through hole; 3, shoulder 4, tup; 5, flute profile breach; 6, the material plane of disruption.

The specific embodiment

In Fig. 1～2, the bottom of being made up of hammer handle (1), prefabricated through hole (2), shoulder (3), tup (4) is provided with the grinder hammerhead of flute profile breach (5), its flute profile breach is located at the middle part of tup (4) bottom, and the trend of flute profile breach parallels with the both sides material planes of disruption (6); The cross sectional shape of its breach is trapezoidal or trapezoidal, also can be arc or triangle.

Have shoulder (3) and manufacture with the structural carbon steel of good toughness with the hammer handle (1) of prefabricated through hole (2), the bottom is provided with the tup good high-chromium alloy cast-iron manufacturing of hardness height, wearability that contains chemical elements such as Cr, Ti, Cu, Ni, Mo, Mn of flute profile breach (5).During manufacturing, the hammer handle (1) that processes is placed on the suitable position that is cast as in the die cavity, the high-chromium alloy cast-iron liquid of fusing is watered in casting in being cast as die cavity then, allow high-chromium alloy cast-iron liquid inject in fusion-casting process in hammer handle shoulder (3) and the prefabricated through hole (2), making hammer handle (1) and tup (4) strong bonded is one.Guaranteeing disintegrating machine when rotating broken material at a high speed, hammer handle can be resisted strong wallop and do not fractureed and come off, and tup has good hardness and wearability and do not worn and torn fast.Owing to be symmetrical arranged before and after the material plane of disruption (6) of tup, when a side material plane of disruption (6) of tup weares and teares, can turn the material plane of disruption that uses opposite side, prolong the service life of tup, improve the synthetic operation benefit of disintegrating machine.

Claims

1. a bottom is provided with the grinder hammerhead of flute profile breach, is made up of hammer handle, tup, and it is characterized in that: flute profile breach (5) is located at the middle part of tup (4) bottom, and the trend of flute profile breach (5) parallels with the both sides material planes of disruption (6).

2. bottom according to claim 1 is provided with the grinder hammerhead of flute profile breach, it is characterized in that: the cross sectional shape of flute profile breach (5) is trapezoidal or trapezoidal, also can be arc or triangle.
