Abstract

The utility model discloses a kind of hammer mill Wear resisting hammer dish, it comprises hammer dish body (1) and outer rim sheath (2), hammer dish body (1) is foursquare Q345 intermediate carbon steel sheet, hammer dish body (1) is established centre bore (3) and tup hole (4), four limits of hammer dish body (1) are installed manganese evanohm plate form outer rim sheath (2) through pin shaft hole (5), bearing pins.Hammer dish of the present utility model adopts square structure, more easily processes, makes whole hammer dish have intensity, toughness and high-wearing feature concurrently, and more common hammer dish improves 8-12 doubly service life, significantly reduces maintenance and cost of manufacture, improves operation rate.

Description

Hammer mill Wear resisting hammer dish

Technical field

The utility model relates to hammer mill, is specifically related to a kind of hammer mill Wear resisting hammer dish.

Background technology

The hammer mill that current metallurgy, mine, building materials, coal, chemical industry, water conservancy, water power etc. use, its hammer dish adopts medium and low carbon steel plate mostly, outer rim wear resistance electrode built-up welding 8-10mm, every built-up welding once generally only can use 7-15 days and just need built-up welding again, each built-up welding needs 2-3 days, and maintenance work is very heavy.Also have and adopt the process of low carbon steel plate nitrogencase hardening, because the depth of quenching is thinner, service life at initial stage slightly extends, and just to have to return the old road of wear resistance electrode built-up welding after quench-hardened case wearing and tearing.Also have employing high manganese steel casting in addition, not only cost is higher, and processing is also more difficult.

Summary of the invention

The purpose of this utility model is: provide a kind of hammer mill Wear resisting hammer dish, its manufacturing cost is lower, easy to process, long service life, maintenance cost are low, operation rate is high, saves energy and reduce the cost, increasing economic efficiency has remarkable influence to production and application unit.

Technical solution of the present utility model is: this hammer mill Wear resisting hammer dish comprises hammer dish body and outer rim sheath, hammer dish body is foursquare Q345 intermediate carbon steel sheet, hammer dish body is established centre bore and tup hole, four limits of hammer dish body are installed manganese evanohm plate form outer rim sheath through pin shaft hole, bearing pins.

Wherein, the thickness of outer rim sheath is greater than hammer dish body thickness.

The utility model has the advantages that: 1, hammer dish body is foursquare Q345 intermediate carbon steel sheet, four limits of hammer dish body are installed manganese evanohm plate form outer rim sheath through pin shaft hole, bearing pins, whole hammer dish is made to have had intensity, toughness and high-wearing feature concurrently, more common hammer dish improves 8-12 doubly service life, significantly reduce maintenance and cost of manufacture, improve operation rate;

2, hammer dish body adopts square structure, more easily processes than circle hammer; 3, four limits of hammer dish body are installed manganese evanohm plate form outer rim sheath through pin shaft hole, bearing pins, increase hammer dish wearability, effectively prevent outer rim from hammering disk material into shape and ftracture, come off, wear and tear; 3, the thickness of outer rim sheath is greater than hammer dish body thickness, protects hammer dish body.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the cross-sectional schematic of Fig. 1.

In figure: 1 hammer dish body, 2 outer rim sheaths, 3 centre bores, 4 tup holes, 5 pin shaft holes.

specific implementation

As shown in Figure 1, 2, this hammer mill Wear resisting hammer dish comprises hammer dish body 1 and outer rim sheath 2, hammer dish body 1 is foursquare Q345 intermediate carbon steel sheet, hammer dish body 1 is established centre bore 3 and tup hole 4, and four limits of hammer dish body 1 are installed manganese evanohm plate form outer rim sheath 2 through pin shaft hole 5, bearing pin.

Wherein, the thickness of outer rim sheath 2 is greater than hammer dish body 1 thickness.
