Description

Technical Field

[0001] The utility model belongs to the field of crushing equipment, and particularly relates to a non-crystalline alloy continuous crushing equipment. Background Art

[0002] The crushing process of non-crystalline alloy casting raw materials (master alloys) is the most front-end raw material processing link in the non-crystalline alloy casting process. The size distribution and uniformity of the crushed materials have a very great influence on the quality of batch-produced non-crystalline alloy parts.

[0003] Taking the prior art as an example, the existing non-crystalline raw material crushing uses a traditional jaw crusher. The large-sized master alloy blocks cast are crushed into small pieces below 5 cm by mechanical crushing, and then used as die-casting raw materials. Although the above technology has simple equipment and process, the mechanical crushing cannot control the size distribution of the crushed materials. There are always 5-8 wt% of powder materials in the crushed materials after the jaw crusher. These overly fine powder materials are oxidized on the surface during the crushing process, so the oxygen content is too high and it is not suitable to be used as die-casting raw materials and can only be remelted. In addition, there will be a part of large blocks that need to be crushed again, which will lead to low efficiency and high energy consumption in the crushing process. Moreover, the jaw crusher can only perform crushing, sorting, and processing in batches and cannot continuously produce, which also makes the master alloy crushing section time-consuming and laborious. Summary of the Invention

[0004] The purpose of the utility model is to provide a non-crystalline alloy continuous crushing equipment, aiming to solve the technical problems of uneven size distribution and low efficiency caused by the inability to continuously produce in the crushing section of non-crystalline alloy casting raw materials (master alloys) in the prior art.

[0005] In order to achieve the above-mentioned utility model purpose, the technical scheme adopted by the utility model is as follows:

[0006] The utility model provides a non-crystalline alloy continuous crushing equipment for crushing non-crystalline rods, including a feeding mechanism, a pushing mechanism, and a crushing mechanism. The non-crystalline rod is a non-crystalline cylindrical rod with uniform composition;

[0007] The non-crystalline rod is fed by the feeding mechanism and falls into the rod groove at a set position, and then is pushed by the pushing mechanism into the crushing mechanism for crushing treatment; the crushing mechanism includes a high-frequency induction heating machine main body and a high-frequency induction heating machine induction coil connected to the high-frequency induction heating machine main body. The pushing mechanism pushes the non-crystalline rod into the induction coil of the high-frequency induction heating machine for crushing treatment.

[0008] The technical solution adopted in the present utility model is completely different from the overall mechanical crushing technical route in the prior art. The crushing method used in the present utility model is as follows: The amorphous raw material is made into a uniform cylindrical rod, and then the amorphous rod is pushed into the induction coil of the high-frequency induction heating machine at a set speed. The cylindrical rod material is instantaneously heated by high-frequency induction heating, so that the surface of the rod material instantaneously rises in temperature. At this time, a temperature difference is formed between the high temperature on the surface of the rod material and the core of the rod material. Due to the brittleness of the amorphous alloy material itself, the thermal stress of the amorphous alloy is relatively high when heated. Therefore, once a large temperature difference and uneven heating are formed between the surface and the core, the rod material will crack instantaneously, just like being broken.

[0009] Preferably, the feeding mechanism includes a feeding baffle, and a fixed plate group and a movable plate group arranged in parallel. The fixed plate group is fixedly installed on the crushing device, and the bottom end of the movable plate group is connected to a cylinder and makes a reciprocating motion under the drive of the cylinder. In the present utility model, by using the combination of the fixed plate group and the movable plate group, continuous feeding of the rod material is completed with the minimum energy consumption.

[0010] Preferably, the fixed plate group includes a first fixed plate and a second fixed plate, and the movable plate group includes a first movable plate and a second movable plate; the first fixed plate, the first movable plate, the second fixed plate, the second movable plate, and the feeding baffle are separately provided and adjacent to each other in sequence. Preferably, the first fixed plate, the first movable plate, the second fixed plate, and the second movable plate all include a plate body and a sliding surface provided at the top end of the plate body, and the angle between the sliding surface and the plate body is 12-30°. Each fixed plate and movable plate completes continuous feeding of the rod material by combining the structural characteristics and the movement mode.

[0011] Preferably, the feeding baffle includes a parallel part parallel to the second movable plate and a feeding inclined edge part, and the included angle between the surface of the feeding inclined edge part and the sliding surface of the second movable plate is 150-180°, and the space for accommodating the raw material rod is formed by the included angle between the two.

[0012] Preferably, at the initial position of the movable plate group, the lower side of the sliding surface of the first fixed plate is adjacent to and higher than the rod material groove; the sliding surfaces of the first movable plate and the second fixed plate are horizontal planes, and this horizontal plane is lower than the sliding surface of the first fixed plate, and the lower side of the sliding surface of the first movable plate is adjacent to the first fixed plate, and the lower side of the sliding surface of the second fixed plate is adjacent to the higher side of the sliding surface of the first movable plate; the lower side of the sliding surface of the second movable plate is adjacent to the higher side of the second fixed plate, and the sliding surface of the second movable plate is lower than the sliding surfaces of the first movable plate and the second fixed plate; the second fixed plate, the second movable plate and the feeding baffle form a space for accommodating the initial feeding rod material.

[0013] Preferably, the pushing mechanism is arranged at the pushing end of the rod groove, and includes a push rod and a push rod power device. The push rod power device includes a lead screw and its power device, a lead screw connection block fixedly sleeved on the lead screw, and a slider fixedly connected to the lead screw connection block. The slider makes a reciprocating motion under the drive of the lead screw along a slide rail parallel to the lead screw. The push rod with a certain pushing speed is used to push one end of the rod, so that the rod enters the induction coil of the high-frequency induction heating machine orderly.

The connecting column is fixedly connected to the push rod, and the push rod moves under the drive of the connecting column; a push rod head is further arranged at the top of the push rod.

[0015] Preferably, a blanking chute is further arranged below the crushing mechanism for collecting the crushed amorphous raw materials.

[0016] Preferably, a frame is further arranged outside the feeding mechanism for protection.

[0017] The utility model provides a device capable of continuously crushing an amorphous alloy raw material rod. By the mutual cooperation of the feeding mechanism, the pushing mechanism and the crushing mechanism, the amorphous alloy raw material rod can be continuously and orderly fed and crushed, so that a stable crushing efficiency is formed in the raw material crushing section. It not only saves time and effort and has high efficiency, but also the size of the crushed raw material rod is uniform without broken materials, greatly reducing the remelting rate of unqualified materials after the crushing of the amorphous alloy raw materials.

For those conditions not specified in the embodiments, they are carried out according to the conventional conditions or the conditions recommended by the manufacturer; for those reagents or instruments not specified by the manufacturer, they are all conventional products that can be obtained through commercial purchase

[0029] In addition, unless otherwise clearly stated in the context, the expression of the singular form of a word should be understood to include the plural form of that word. The terms "comprising" or "having" are intended to specify the presence of features, quantities, steps, operations, elements, parts, or combinations thereof, but are not used to exclude the presence or possible addition of one or more other features, quantities, steps, operations, elements, parts, or combinations thereof

[0030] The embodiments of the present utility model provide a non-crystalline alloy continuous crushing device capable of uniformly crushing non-crystalline alloys, and its structural schematic diagram is as shown in Appendix Figure 1 to Appendix Figure 6 as shown

[0031] Specifically, the device is used for crushing amorphous material rods. Its main structure includes a feeding mechanism, a pushing mechanism, and a crushing mechanism. The amorphous material rods to be crushed are amorphous cylindrical rods with uniform composition. Emphasizing "uniform composition" means that during the process of melting and rod forming of the amorphous material rod, the uniformity of the chemical composition of the rod must be ensured to avoid heat deviation due to non-uniform composition during induction heating treatment, which may cause the rod to fail to break apart. Further, if the composition of the rod is not uniform, when used as a master alloy after crushing, it will also cause non-uniform composition of the amorphous alloy casting during the die-casting process, resulting in defects.

[0032] The amorphous material rod is fed by the feeding mechanism and falls into the rod groove 123 at the set position, and then is pushed by the pushing mechanism into the crushing mechanism for crushing treatment. The crushing mechanism includes the main body 101 of the high-frequency induction heating machine and the induction coil 104 of the high-frequency induction heating machine connected to the main body of the high-frequency induction heating machine. The pushing mechanism pushes the amorphous material rod 112 into the induction coil 104 of the high-frequency induction heating machine for crushing treatment.

[0033] The feeding mechanism includes a feeding baffle 122 and a fixed plate group and a movable plate group arranged in parallel. The fixed plate group is fixedly installed on the crushing equipment, and the bottom end of the movable plate group is connected to the cylinder 121 and makes a reciprocating motion driven by the cylinder 121.

[0034] Specifically, the fixed plate group includes a first fixed plate 117 and a second fixed plate 119, and the movable plate group includes a first movable plate 118 and a second movable plate 120. The first fixed plate 117, the first movable plate 118, the second fixed plate 119, the second movable plate 120, and the feeding baffle 122 are separately established and adjacent to each other in sequence.

[0035] The first fixed plate 117, the first movable plate 118, the second fixed plate 119, and the second movable plate 120 all include a plate body and a sliding surface provided at the top of the plate body. Taking the structure of the first fixed plate 117 as an example, the first fixed plate 117 includes a plate body 1171 and a sliding surface 1172 provided at the top of the plate body. The cross-section of the first fixed plate 117 is in the shape of a right trapezoid, and the shapes of other fixed plates and movable plates are similar, but with different lengths. Figure 5

[0036] The angle between the sliding surface of each plate body and the plate body is within the range of 12 to 30°, as shown in the attachment, just forming a slope on which the rod can roll. As shown in the attachment, the feeding baffle 122 includes a parallel part 1222 parallel to the second movable plate 120 and a feeding bevel part 1221. The angle between the surface of the feeding bevel part 1221 and the sliding surface of the second movable plate 120 is 150 to 180°, forming an inclined groove that can accommodate the rod, and the rod can roll along the slope in the inclined groove. Figure 3 Figure 6

[0037] ​​​At the initial position of the movable plate group ( Figure 4 ), the lower side of the sliding surface of the first fixed plate 117 is adjacent to and higher than the rod groove 123. With such a design, once the rod rolls onto the sliding surface of the first fixed plate 117, it can continue to roll into the rod groove. The sliding surfaces of the first movable plate 118 and the second fixed plate 119 are horizontal planes, which are lower than the sliding surface of the first fixed plate 117. The lower side of the sliding surface of the first movable plate 118 is adjacent to the first fixed plate 117, and the lower side of the sliding surface of the second fixed plate 120 is adjacent to the higher side of the sliding surface of the first movable plate 118. The lower side of the sliding surface of the second movable plate 120 is adjacent to the higher side of the second fixed plate 119, and the sliding surface of the second movable plate 120 is lower than the sliding surfaces of the first movable plate 118 and the second fixed plate 119. The second fixed plate 119, the second movable plate 120 and the feed baffle 122 form a receiving space for the initial feed rods.

[0038] In the actual structural design, for the convenience of connection, a cylinder fixing block 108 is fixedly connected to the cylinder 121. The cylinder fixing block 108 is then connected to the cylinder connecting block 107, and the cylinder connecting block 107 is connected to the movable plate group. That is, the first movable plate 118 and the second movable plate 120 are fixedly connected to the cylinder connecting block 107, so as to move under the drive of the cylinder 121.

[0039] It can be seen from the drawings that the process of rod feeding is as follows: At Figure 4 the shown initial position, the rods are put in by manual or mechanical means in the direction shown in the drawings, forming a rod pile 105. Under the action of natural gravity, there will be several rods on the second movable plate 120.

[0040] At this time, the cylinder 121 is started, so that the cylinder 121 drives the movable plate group to move upward. The second movable plate 120 will then push a rod stuck between itself and the second fixed plate 119 upward until it contacts the sliding surface of the second fixed plate 119. Then, under the action of gravity, the rod rolls from the sliding surface of the second movable plate 120 to the sliding surface of the second fixed plate 119 due to the slope difference of each plate and gets stuck between the second fixed plate 119 and the first movable plate 118. At this time, the second movable plate 118 moves upward to the side of the first fixed plate 117.

[0041] The cylinder 121 is started again to drive the movable plate group to reset downward. When the first movable plate 118 and the second fixed plate 119 are reset to the initial position as shown in Figure 4 , the rod rolls from the sliding surface of the second fixed plate 119 to the sliding surface of the first movable plate 118.

[0042] The cylinder 121 is activated again to drive the movable plate group to move upward. On the one hand, after the top of the material rod on the sliding surface of the first movable plate 118 reaches the same level as the first fixed plate 117, it rolls to the sliding surface of the first fixed plate 117 due to the slope difference and finally rolls into the material rod groove 123. On the other hand, the second feeding material rod repeats the above feeding action to ensure continuous feeding.

[0043] Combined with Figure 2 and Figure 3 , the pushing mechanism is arranged at the pushing end of the material rod groove 123 and includes a push rod 114 and a push rod power device. The push rod power device includes a lead screw 106 and its power motor 109, a lead screw connection block 111 fixedly sleeved on the lead screw 106, and a slider 116 fixedly connected to the lead screw connection block 111. The slider 116 makes a reciprocating motion along a slide rail 110 parallel to the lead screw 106 driven by the lead screw 106. The pushing mechanism further includes a connecting column 113 fixedly connected to the lead screw connection block 111. The connecting column 113 is fixedly connected to the push rod 114, and the push rod 114 moves driven by the connecting column 113. A push rod head 115 is also provided at the top of the push rod 114.

[0044] The crushing equipment in this embodiment further includes a blanking chute 103 arranged below the crushing mechanism and a frame 102 arranged outside the feeding mechanism. After the material rod 112 enters the material rod groove 123, the power motor 109 of the lead screw is activated to drive the lead screw to move. The lead screw then drives the lead screw connection block 111 to move towards the crushing side, and the slider 116 moves along the slide rail 110 towards the crushing side driven by the lead screw connection block 111. In this way, the connecting column 113 can push the push rod 114 to move smoothly at a constant speed. The push rod head 115 at the front end of the push rod 114 is then pushed to contact the material rod 112, and then the thrust is applied to the tail end of the material rod to push the material rod into the induction coil 104 of the high-frequency induction heating machine. One end of the material rod is continuously crushed, and the other end is continuously pushed into the coil until the entire material rod is completely crushed. Then, the feeding mechanism is activated for feeding, thus achieving the technical purpose of continuous crushing.

[0045] It can be seen from the above embodiments that the amorphous alloy continuous crushing equipment in the present invention can continuously crush the amorphous alloy raw material rod without interruption. By the mutual cooperation of the feeding mechanism, the pushing mechanism and the crushing mechanism, the amorphous alloy raw material rod can be continuously and orderly fed and crushed, so that a stable crushing efficiency is formed in the raw material crushing section. It not only saves time and effort and has high efficiency, but also the size of the crushed raw material rod is uniform without broken materials, greatly reducing the remelting rate of unqualified materials after the crushing of amorphous alloy raw materials.

[0046] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
