Embodiment Construction

[0024] Such as figure 1 As shown, the shovel seat of a Raymond mill of the present invention is a whole, the main seat end 1 is installed on the shovel barrel, and the auxiliary seat end 3 is used to install the shovel. There is a folded plate 4 between the main seat end 1 and the auxiliary seat end 3 , and there is a knuckle line 2 between the folded plate 4 and the main seat end 1 .

[0025] Such as figure 2 , on the back side, a reinforcing plate 5 is set between the auxiliary seat end 3 and the folded plate 4, and a positioning strip 6 is set at the bend between the main seat end 1 and the folded plate 4.

[0026] Its preparation method includes:

[0027] 1) Cutting: Obtain an A3 steel plate with a size that meets the requirements;

[0028] 2) Calcined at 850-1000°C;

[0029] 3) Forging and forming;

[0030] 4) natural cooling, drilling;

[0031] 5) Weld the reinforcement plate 5 between the auxiliary seat end 3 and the folded plate 4 on the back;

[0032] 6) Weld ...

Abstract

The invention discloses a Raymond mill scraper knife seat which is made of an A3 steel press forging piece. A manufacture method of the Raymond mill scraper knife seat comprises the following steps: (1) blanking; (2) calcining at the temperature of 850-1000 DEG C; (3) forging and pressing for forming; and (4) naturally cooling, and punching, or also comprises the step of (5) welding a reinforced plate between an auxiliary seat end at the back surface and a folding plate, or also comprises the step of (6) welding a positioning strip at a main seat end at the back surface and the bending part of the folding plate. Compared with a common casting in the prior art, the Raymond mill scraper knife seat has the advantages of being not prone to break, durable, low in cost, convenient to process, easy in quality control, stable in shape, convenient to install, and the like.

Description

technical field [0001] The invention relates to a Raymond mill component, in particular to a Raymond mill blade holder and a preparation method thereof. Background technique [0002] Raymond mill is called Raymond mill for short, and its full English name is Raymond mill. It is suitable for various mineral powder preparation and coal powder preparation, such as fine powder processing of raw material ore, gypsum ore, coal and other materials. The main machine of Raymond mill is composed of frame, air inlet volute, blade, grinding roller, grinding ring, cover and motor. [0003] The Raymond mill blade is one of the common accessories inside the Raymond mill, and it is also one of the important accessories during the milling work. The grinding principle is as follows: when the machine is running, the grinding rod generates a centrifugal force and presses against the grinding ring to form a grinding force, and uses this grinding force and the grinding rod to make circular moti...
