Abstract

The utility model discloses a composite alloy hammer for a hammer type crusher, which comprises a hammer head and a hammer handle. The hammer handle is formed by casting high-manganese steel; the hammer head is made of high-chromium cast iron materials; and the part between the hammer head and the hammer handle is formed by compositing in an inlaying or mechanical combination or fusion-welding manner. The utility model has the beneficial effects that the wear resistance of the composite alloy hammer is more than three times of that of a common hammer head; the use is safe; and the breakage cannot occur; the production efficiency is greatly improved; the labor intensity of labors is reduced; and the production cost is reduced.

Description

Hammer mill composite alloy hammer

Technical field

The utility model relates to a kind of parts of hammer mill.

Background technology

Stone crusher mainly comes the building stones in the hammering entering machine through stonebreakers' hammer, and it is carried out fragmentation.The tup of existing hammer mill is by the moulding of potassium steel one-step casting, or by medium carbon steel forging molding (hereinafter to be referred as common tup).Its main wearing part tup wearability is far away from the tup of rich chromium cast iron material.Have on the market now a kind of in, the hammer handle of low-carbon steel material adds the combination hammer of the tup of rich chromium cast iron material with solid, liquid mode casting; The tup part wearability of its rich chromium cast iron material has raising, but the hammer handle part anti-wear performance of middle low carbon steel material is relatively poor.In the actual production utilization, take place that tup partly weares and teares seldom and the hammer handle part is rubbed or worn out and out of use situation through regular meeting.Have a strong impact on production efficiency, even cause the device security accident, as interrupt sieve plate, grating, main shaft, pair plate etc.

The utility model content

The purpose of the utility model provides a kind of tup and hammer handle all has high anti-wear performance, the hammer mill composite alloy hammer that safety coefficient is high.

The technical scheme of the utility model is:

Hammer mill composite alloy hammer comprises tup and hammer handle.Wherein, hammer handle is by the potassium steel casting, and tup is made up of the rich chromium cast iron material; Be composited with castingin or mechanical compound mode between tup and the hammer handle.

Perhaps, another technical scheme of the utility model is:

Hammer mill composite alloy hammer comprises tup and hammer handle.Wherein, hammer handle is by the potassium steel casting, and tup is made up of the rich chromium cast iron material; Tup and hammer handle adopt the melting welding mode to be composited, and also are formed with one deck fused layers at the two contact-making surface of the tup of the hammer handle of potassium steel and rich chromium cast iron.

The positive progressive effect of the utility model is that wearability is more than 3 times of common tup, and is safe in utilization; Do not rupture, improved production efficiency greatly, per hour go out husky material and improve 1 times, power consumption minimizing 15%; Alleviate working strength of workers, reduced production cost.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment one;

Fig. 2 is the structural representation of the utility model embodiment two.

The specific embodiment

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

Embodiment 1:

Present embodiment adopts the castingin mode.As shown in Figure 1, present embodiment hammer mill composite alloy hammer comprises tup 1 and hammer handle 2.Wherein, hammer handle 2 is by the potassium steel casting, and tup 1 is made up of the rich chromium cast iron material; Be composited with castingin or mechanical compound mode between tup 1 and the hammer handle 2.

Embodiment 2:

Present embodiment adopts the melting welding mode.As shown in Figure 2, present embodiment hammer mill composite alloy hammer comprises tup 1 and hammer handle 2.Wherein, hammer handle 2 is by the potassium steel casting, and tup 1 is made up of the rich chromium cast iron material; Tup 1 adopts the melting welding modes to be composited with hammer handle 2, also is formed with one deck fused layers 3 at the two contact-making surface of the tup of the hammer handle 2 of potassium steel and rich chromium cast iron 1.

The hammer mill composite alloy of the utility model is hammered the Technology for Heating Processing under the practicable same temperature into shape, its hammer handle impact toughness＞200ak/J.cm ², fatigue strength＞400/J.cm ²σ b/MPa, percentage elongation＞25 δ/%, break face shrinkage factor＞30 ψ/%, HRC15, reach the mechanical property of working environment fully.Material that extremely valuable is is the hammer handle of potassium steel, under working environment, because the impact of building stones; Its surface can form the wearing layer of high rigidity; Can form new high hardness wear-resisting layer on new surface again after the surface wear-resistant layer wearing and tearing; And its inside still keeps the good mechanical performance, is that the tup of rich chromium cast iron weares and teares synchronously, overall wear resistance reaches consistent thereby reach with material.

The wearability of the utility model is more than 3 times of common tup, and is safe in utilization, do not rupture, and improved production efficiency greatly, per hour goes out husky material and improves 1 times, power consumption minimizing 15%, alleviated working strength of workers, reduced production cost.

Claims

1. hammer mill composite alloy hammer comprises tup and hammer handle, it is characterized in that hammer handle by the potassium steel casting, and tup is made up of the rich chromium cast iron material; Be composited with castingin or mechanical compound mode between tup and the hammer handle.

2. hammer mill composite alloy hammer comprises tup and hammer handle, it is characterized in that hammer handle by the potassium steel casting, and tup is made up of the rich chromium cast iron material; Tup and hammer handle adopt the melting welding mode to be composited, and also are formed with one deck fused layers at the tup of the hammer handle of potassium steel and the rich chromium cast iron contact-making surface between the two.
