Description

A kind of squeezing crusher

Technical field

The utility model belongs to the crushing mechanism field, relates in particular to a kind of squeezing crusher of preparation steel powder in the powder metallurgy industry.

Background technology

In the powder metallurgy industry, preparation reduced iron powder used raw material are sponge iron, sponge iron fire finish after, carry out coarse crushing, the pintongs the sponge iron attrition crushing becomes vertical folds in a garment to split carries out fine crushing again through after cleaning with water then.The coarse crushing equipment that is used for sponge iron at present, a kind of of usefulness is Large Crusher usually, needs higher speed running, complicated operation, wear and tear in machines is fast, and the maintenance cost height is not suitable for the fragmentation of the less sponge iron of volume; Another kind is artificial hammer crushing, needs great amount of manpower, and crushing efficiency is not high, and the sponge iron after the fragmentation is inhomogeneous, influences the carrying out of next procedure.

Summary of the invention

The purpose of this utility model is exactly at the existing in prior technology deficiency, and a kind of squeezing crusher is provided, and this disintegrating machine is easy and simple to handle, scale is moderate, makes regular shape after the sponge iron fragmentation, size evenly.

The technical solution of the utility model is: a kind of squeezing crusher, comprise that frame, dust gathering arrester, motor, roller, balance get rid of wheel, belt pulley, roller is horizontally fixed on the frame by rotating shaft, one side of rotating shaft links by belt pulley and motor, rotating shaft opposite side and balance are got rid of wheel and are linked, and the back downside of described roller has a jaw, the axially parallel of jaw and roller, the upper end of jaw is hinged by bearing pin and frame, is connected by spring between jaw lower end and the frame.Described spring and jaw lower end rear side are hinged, fixedly connected with frame.By the extruding of roller and jaw, sponge iron is broken into regular shape, sponge iron blocks of uniform size; Be connected by spring between jaw lower end and the frame, the effective distance between dancer rools and jaw can cushion the impulsive force of countershaft in the machine operation procedure, has both reduced noise, can effectively prevent the fracture of rotating shaft again, the service life of having improved whole machine,

Many the projections parallel with the roll axis direction are arranged on the described roller.Increased the frictional force of roller and storeroom so greatly, prevented that material from skidding on jaw, reduced wearing and tearing jaw.

The beneficial effects of the utility model are: because the back downside of squeezing crusher central roll has a jaw, and the axially parallel of jaw and roller, the upper end of jaw is hinged by bearing pin and frame, is connected by spring between jaw lower end and the frame.This disintegrating machine is easy and simple to handle, scale is moderate, motor speed is suitable, and is safe in utilization, long service life, improved crushing efficiency, after the sponge iron fragmentation, size is even, regular shape, be convenient to subsequent operation processing, be applicable to the preliminary fragmentation of powder used in metallurgy sponge iron, help eliminating the following process sclerosis, improve the quality of reduction steel powder.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

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

Fig. 2 be among Fig. 1 A-A to cross-sectional schematic,

Fig. 3 is the structural representation of C direction among Fig. 2.

Among the figure: 1 is motor, and 2 is belt pulley, and 3 for rotating shaft, and 4 is bearing pin, and 5 is roller, 6 these projections, and 7 is dust gathering arrester, and 8 get rid of wheel for balance, and 9 is frame, and 10 is jaw, 11 is spring.

The specific embodiment

According to Fig. 1, Fig. 2 and shown in Figure 3, a kind of squeezing crusher, comprise frame (9), dust gathering arrester (7), motor (1), roller (5), balance is got rid of wheel (8), belt pulley (2), roller (5) is horizontally fixed on the frame (9) by rotating shaft (3), one side of rotating shaft (3) links by belt pulley (2) and motor (1), rotating shaft (3) opposite side and balance are got rid of wheel (8) and are linked, the back downside of described roller (5) has a jaw (10), the axially parallel of jaw (10) and roller (5), the upper end of jaw (10) is hinged by bearing pin (4) and frame (9), be connected by spring (11) between jaw (10) lower end and the frame (9), spring (11) is hinged with jaw (10) lower end rear side, fixedly connected with frame (9), many projections (6) parallel with roller (5) axis direction are arranged on the roller (5).Balance is got rid of wheel (8) and is played the effect that makes the entire machine balance and stability, motor (1) drives rotating shaft (3) by belt pulley (2) and roller (5) rotates, along with roller (5) rotates towards the direction of jaw (10), columned sponge iron is brought between roller (5) and the jaw (10), by the extruding of roller (5), sponge iron is broken into regular shape, sponge iron blocks of uniform size with jaw (10); Be connected by two springs (11) between jaw (10) lower end and the frame (9), make jaw (10) can certain be the center rotation among a small circle with the bearing pin (4) of jaw (10) upper end, can make material more evenly broken according to the gap between how many dancer rools that enter material (5) and the jaw (10) like this.Be applicable to the fragmentation of small-sized circular sponge iron, crushing effect is fine, can be widely used in the steel powder preparation process in the powder metallurgy.
