Description

Technical Field

[0001] The utility model patent relates to a shaping machine, in particular to a shaping machine material distribution plate which is used in conjunction with a shaping machine rotor and has replaceable worn parts. Background Art

[0002] Impact shaping machine is an essential equipment for the production of building aggregate stone and machine-made sand. Stone and machine-made sand of various particle sizes can be shaped by shaping machine to obtain rounded grains of stone or sand that meet national standards, thereby improving the quality grade of stone or sand. All the feed of the impact shaping machine must pass through the distribution plate to evenly distribute the materials entering the impact shaping machine. Then, relying on the centrifugal force of the rotor, the materials are impacted against the counterattack material lining around the machine cavity of the shaping machine or the materials in the shaping cavity collide with each other, so as to achieve the purpose of crushing and shaping the materials. The distribution plate matched with the rotor of the existing impact shaping machine is generally made of high-chromium cast iron and air-cooled quenching treatment. The distribution plate on the conventional shaping machine generally relies on the gravity of the distribution plate itself and is directly embedded in the groove of the rotor bracket. However, when the shaping machine is working, if there is a sudden imbalance in the rotor operation, a failure in the upper and lower bearings of the rotor, or an emergency shutdown, the distribution plate is very easy to be thrown out, causing a quality accident. In order to improve the safety of the high chromium cast iron distributor plate, a distributor plate with fixing bolts is generally designed, which can ensure that the distributor plate is tightly fixed on the rotor bracket and will not be thrown out. Since most of the materials in the shaping cavity of the shaping machine are thrown into the shaping cavity through the distributor plate, the working part of the distributor plate is seriously worn and needs to be replaced frequently.

[0003] In addition, as the shaping machine becomes larger, the rotors are all deep-cavity type, so the diameter and thickness of the feed plate will also increase accordingly, generally from 80-100 mm thick to 180-200 mm thick. Such a thick feed plate will store more hot melt when it is air-cooled in the heat treatment furnace. Since the feed plate is generally made of high-chromium cast iron, the high-chromium cast iron is quenched by air cooling. As the diameter and thickness of the feed plate increase, the depth of the hardened layer of the feed plate becomes shallow, and even the core part cannot be hardened through, which directly affects the wear resistance of the feed plate and reduces the overall service life of the large feed plate. Sometimes, in order to improve the overall hardenability of the large feed plate and increase its service life, it is necessary to increase the content of precious metals such as molybdenum, vanadium, titanium, and nickel in the chemical composition of high-chromium cast iron, resulting in a substantial increase in production costs. Summary of the invention

[0004] For this purpose, a split-type material distribution plate is specially designed. The purpose of the utility model is to provide a shaping machine material distribution plate with replaceable worn parts, by dividing the material distribution plate into two parts: a main body of the replaceable worn parts of the shaping machine material distribution plate and a base of the shaping machine material distribution plate, and then fixing these two parts on the main shaft of the shaping machine rotor by bolts. With such a split design, when the main body of the replaceable worn parts of the shaping machine material distribution plate at the severely worn parts is worn out, the main body of the replaceable worn parts of the shaping machine material distribution plate is directly replaced without replacing the base of the shaping machine material distribution plate, and the replacement of the severely worn parts is convenient and fast, which greatly increases the service life of the material distribution plate and reduces the cost. It avoids the accident of the material distribution plate being thrown out during the work process, improves the safety of the use of the material distribution plate; reduces the production cost of the shaping machine material distribution plate, increases the service life of the material distribution plate, and reduces the overall operation and production cost of the shaping machine.

[0020] The following is combined with Figure 1-Figure 3 The structure and working process of the utility model are specifically described in detail.

[0021] A shaping machine feed plate with replaceable wear parts, comprising a shaping machine feed plate replaceable wear part body 1 and a shaping machine feed plate base 2, wherein the shaping machine feed plate replaceable wear part body is arranged above the shaping machine feed plate base, and a shaping machine rotor main shaft is arranged below the shaping machine feed plate base, and fastening bolts 3 pass through the shaping machine feed plate replaceable wear part body and the shaping machine feed plate base in sequence to fix the shaping machine feed plate replaceable wear part body and the shaping machine feed plate base on the shaping machine rotor main shaft. The shaping machine feed plate replaceable wear part body 1 is the wear part of the feed plate, and its function is to make the material entering the shaping machine rotor be thrown toward the shaping cavity along the feed plate under the action of the centrifugal force of the rotor. The shaping machine feed plate base 2 is the basic part of the split feed plate, which is installed in the shaping machine rotor to increase the overall thickness and structural strength of the large shaping machine feed plate.

[0022] The utility model discloses a shaping machine distribution plate with replaceable worn parts, wherein the bottom center part of the body of the shaping machine distribution plate with replaceable worn parts is arranged as an inverted cone structure, and a corresponding inverted cone groove is arranged at the top center part of the base of the shaping machine distribution plate. The inverted cone structure at the bottom center part of the body of the shaping machine distribution plate with replaceable worn parts is engaged in the inverted cone groove at the top center part of the base of the shaping machine distribution plate.

[0023] The utility model discloses a shaping machine material distribution plate with replaceable worn parts, wherein the center of the body of the shaper machine material distribution plate with replaceable worn parts is provided with an inner screw hole, and the fastening bolt is a hexagon socket bolt.

[0024] The utility model discloses a shaping machine material distribution plate with replaceable worn parts, wherein the shaping machine material distribution plate base is a medium chromium alloy steel material distribution plate base, which can ensure a certain wear resistance and good mechanical strength.

[0025] The utility model discloses a shaping machine material distribution plate with replaceable worn parts, wherein the material body of the shaping machine material distribution plate with replaceable worn parts is made of high chromium cast iron Cr 20 MoCuVRE material.

[0026] The working process of the utility model is as follows:

[0027] The utility model splits the material distribution plate into two parts. According to the specific situation of the wear and failure of the material distribution plate of the large-scale shaping machine and the specific structure of the deep cavity rotor, the material distribution plate is split at the best wear and replacement position, and is respectively divided into: the replaceable wear part body 1 of the shaping machine material distribution plate, the shaping machine material distribution plate base 2, and the shaping machine split material distribution plate fastening bolts 3. In order to fasten firmly with bolts, the center part of the replaceable wear part body 1 of the shaping machine material distribution plate and the connection of the shaping machine material distribution plate base 2 are designed to be an inverted cone structure; the outer circle part of the replaceable wear part body 1 of the shaping machine material distribution plate and the outer circle connection of the shaping machine material distribution plate base 2 are designed to be a positive cone structure. This ensures that the split material distribution plate is firmly combined and can be used safely.

[0028] In order to reduce production costs, the material of the shaping machine's material distribution plate base 2 is changed from expensive high-chromium cast iron material to relatively low-chromium alloy steel material. This not only takes into account its wear resistance but also improves its structural strength, and it can be fastened with bolts without breaking.

[0029] Since the thickness of the replaceable wear part body 1 is thinned, the depth of the heat treatment hardening layer is guaranteed and the wear resistance is improved.

[0030] In order to improve the safety of the material distribution plate body in use, high-strength hexagonal bolts are used to fasten the replaceable wear part body 1 of the material distribution plate of the shaping machine and the base 2 of the material distribution plate of the shaping machine to the main shaft of the rotor of the shaping machine.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
