Description

Technical Field

[0001] The utility model belongs to the technical field of alloy crushing equipment, and in particular relates to a material rod crusher. Background Art

[0002] The existing amorphous alloy master alloy production and preparation process is to melt the amorphous raw materials evenly and then cast them into plates of a certain size, and then use a jaw crusher for multi-stage crushing until all the raw materials are crushed into block fragments with a maximum size of less than 40mm, which can be put into the casting process for use after screening. The crushing method in the prior art is relatively rough, which will lead to uneven size of the crushed fragments. The limit values ​​of the fragment size - the maximum and minimum values ​​- are quite different, which will bring processing difficulties to the weighing steps in the subsequent process. Generally speaking, the amorphous master alloy crushed by the jaw crusher will have 15wt% of the fragments with a size less than 2mm. Such small-sized fragments are often scrapped due to excessive oxygen content. In addition, there will be 5wt% of the fragments that need to be sorted out and crushed again for weighing in the subsequent process. The above situation affects the material recovery rate in the amorphous master alloy crushing process, and indirectly increases the cost of amorphous product production.

[0003] Obviously, the simple and crude existing crushing method is no longer suitable for the crushing process of amorphous master alloy for casting, which requires precise control. Summary of the invention

[0047] In order to make the purpose, technical scheme and technical effect of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model is clearly and completely described. The embodiments described below are part of the embodiments of the utility model, not all of the embodiments. In combination with the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. If the specific conditions are not specified in the embodiments, they are carried out according to the conventional conditions or the conditions recommended by the manufacturer; the reagents or instruments used without indicating the manufacturer are all conventional products that can be purchased commercially.

[0048] In addition, unless the context clearly uses otherwise, the expression of the singular form of a word should be understood to include the plural form of the word. The term "includes" or "having" is intended to specify the existence of a feature, quantity, step, operation, element, part or combination thereof, but is not used to exclude the existence or possible addition of one or more other features, quantities, steps, operations, elements, parts or combinations thereof.

[0049] The utility model provides a rod crusher for uniformly cutting amorphous alloy rods, and its structure is as shown in the attached figure. Figure 1 Only attached Fig. 9 shown.

[0050] The material rod crusher provided in the embodiment includes an elastic clamping mechanism, a pushing mechanism, a sensing mechanism and a cutter, wherein the pushing mechanism is arranged at the feed end of the elastic clamping mechanism, and the sensing mechanism and the cutter are arranged at the discharge end of the elastic clamping mechanism. The elastic clamping mechanism is provided with a discharge channel, and the pushing mechanism pushes the material rod to be processed from the discharge channel from the feed end, and the sensing mechanism is provided with a sensor, and after the sensor senses that the material rod extends to a set length, the elastic clamping mechanism clamps the material rod, and the cutter cuts the material rod. In short, the material rod crusher completes the automated process of uniformly cutting the amorphous alloy material rod.

[0051] The rod crusher provided in this embodiment is used to process amorphous alloy rods. Unlike conventional crystalline alloys, amorphous alloys have low plasticity and certain brittleness. The rods can be easily cut off using a cutter, but this processing method is not feasible for plastic alloy materials such as stainless steel and aluminum alloy.

[0052] It should be noted that the "material rods" processed in the present invention do not only refer to round rods. Although the example given in this embodiment is a cylindrical rod, in actual application, as long as the rod can be stably installed in the discharge channel, or the lower mold insert can be replaced according to the rod to be processed, the application scope of the material rod crusher in the present invention can be further expanded. The equipment can also evenly cut long strips or other rod-shaped amorphous alloys that are squeezed and deformed.

[0053] Specifically, the elastic clamping mechanism includes an upper mold assembly 21 and a lower mold assembly 31. The upper mold assembly 21 includes a first upper mold block 202 and a second upper mold block 204 that are identical in structure and installed in parallel. The first upper mold block 202 and the second upper mold block 204 are both concave blocks with a concave portion in the middle (such as the attached Figure 4 , 5 ).

[0054] As attached Figure 3 , Attachment Figure 4 The elastic clamping mechanism also includes an upper and lower mold clamping assembly, and the upper mold assembly 21 is arranged above the lower mold assembly 31. The upper and lower mold clamping assembly includes upper and lower mold positioning guide blocks 104 arranged on both sides of the lower mold assembly and upper and lower mold positioning guide pillars 115 arranged on the upper and lower mold positioning guide blocks 104. The upper and lower mold positioning guide pillars 115 are telescopic pillars that can be retracted under pressure and are connected to the second upper mold block 204 in the upper mold assembly. The retractable distance of the upper and lower mold positioning guide pillars 115 is greater than the distance between the upper mold assembly 21 and the lower mold assembly 31. In other words, when the upper mold assembly receives pressure from top to bottom, the upper and lower mold positioning guide pillars 115 will also shrink and drop under the action of the pressure, so that the upper mold assembly is pressed on the top of the lower mold assembly, and the force is transmitted from top to bottom.

[0055] A pre-tightening mechanism is provided between the first upper module 202 and the second upper module 204, and the pre-tightening mechanism includes an upper die spring guide column 208 provided between the two upper modules and an upper die spring 203 sleeved on the upper die spring guide column 208. The pre-tightening mechanism also includes an upper die spring guide column hole 207 for installing the upper die spring guide column 208 and an upper die spring positioning hole 206 for installing the upper die spring 203, which are provided on the first upper module 202 and the second upper module 204. The upper die spring guide column hole 207 and the upper die spring positioning hole 206 are concentric holes and are blind holes, which are used to fix and position the upper die guide column and the upper die spring. The upper die spring guide column 208 is shorter than the upper die spring 203. The first upper module 202 and the second upper module 204 are provided with threaded connection holes at both ends for connection, and also include an upper module connection column 205 installed in the connection hole. The upper module connection column 205 is a bolt structure. Tightening the upper module connection column 205 to connect the two upper modules puts the two upper modules in a pre-tightened state.

[0056] It can be seen from the above structure that after the upper module connecting column 205 is tightened, the upper die spring can be pre-pressed to form a pre-tightened state. The upper die spring 203 can only be extended and retracted up and down within a certain distance along the spring guide column under the limitation of the upper die spring guide column 208 and the upper die spring positioning hole 206, so that the first upper module 202 and the second upper module 204 move relative to each other.

[0057] It should be noted that, in the process of explaining this embodiment, in order to more clearly describe the structure of the device in this embodiment, the working units that appear in groups will not be repeated. For example, the upper die spring, upper die connecting column, upper die spring positioning hole, upper die spring guide column hole, and upper die spring guide column in the upper die module assembly all appear in groups, and also include the lower die spring, lower die positioning column, lower die spring positioning hole, lower die spring guide column, lower die positioning column hole, etc. described later. Those skilled in the art can clearly understand that the purpose of designing the above structures symmetrically in groups is to make the equipment run more stably and more efficiently, etc. The same approach will be adopted in the subsequent description of the lower die assembly.

[0058] In this embodiment, the number of the upper die spring guide pillars and the upper die springs is 4, and they are symmetrically arranged along the central axis of the first upper die block and the second upper die block, so that the equipment is more stable and efficient during operation. In actual use, it can be selected according to actual needs.

[0059] Furthermore, the rod crusher in this embodiment also includes a machine tool 101 and an equipment base 11, and a cutter punch block 102 (attached) is provided on the machine tool 101. Figure 1). The first upper module 202 is fixedly connected to the upper mold block 201 on the side facing away from the second upper module. The upper mold block 201 is provided with a cutter punch block connection block 118. The cutter punch block connection block 118 is fixedly connected to the cutter punch 102. The cutter punch 102 drives the first upper module 202 to move. The cutter 116 is installed between the concave parts of the two upper modules, and the handle of the cutter 116 is fixedly connected to the concave part of the first upper module 202. The cutter 116 moves under the drive of the first upper module 202.

[0060] As attached Figure 7 Specifically, the lower die assembly of the material bar crusher in this embodiment includes a first lower die block 301 and a second lower die block 302 with the same structure and installed in parallel. The first lower die block 301 is embedded with a first lower die block 304, and the second lower die block 302 is embedded with a second lower die block 305. The first lower die block 304 and the second lower die block 305 have the same structure and are both provided with a through groove structure. The integral through groove formed after the two are molded together constitutes the discharge channel 117 of the material bar 107. The shape of the discharge channel 117 and the material bar 107 are a compatible clamping structure. The structure is set here to allow the elastic clamping mechanism to use the structure of the two lower die blocks to press the material bar into the block without moving when subjected to pressure from top to bottom, so as to facilitate cutting by the cutter. In this embodiment, the through groove structure of the lower die block is V-shaped, and the material bar to be processed is cylindrical. After being subjected to force, the material bar can be tightly pressed into the lower die block group.

[0061] In other embodiments, the material rod may be selected to be in the shape of a long strip, and the through groove of the lower die insert may be in the shape of a strip groove, both of which can achieve the technical purpose.

[0062] A pre-tightening mechanism is provided between the first lower module 301 and the second lower module 302. The pre-tightening mechanism includes a lower die spring guide post 308 provided between the two lower modules and a lower die spring 303 sleeved on the lower die spring guide post 308. The lower die spring guide post 308 is shorter than the lower die spring 303. The first lower module 301 is provided with a lower die spring guide post hole, through which the lower die spring guide post 308 is inserted. The lower die spring guide post hole is a threaded hole, and the lower die spring guide post 308 is a bolt structure. The second lower module 302 is provided with a lower die spring positioning hole 307 for installing the lower die spring 303. The lower die spring positioning hole 307 is a blind hole.

[0063] Preferably, the number of the lower die spring guide pillars 308 and the lower die springs 303 is two, which are disposed on both sides of the lower die assembly and are symmetrically arranged along the central axis of the first lower die block 301 and the second lower die block 302 .

[0064] Lower module positioning column holes 309 are provided at both ends of the first lower module 301, and the second lower module 302 is provided with protruding lower module positioning columns 306 that are compatible with the lower module positioning column holes 309. After the lower module positioning columns 306 are inserted into the corresponding lower module positioning column holes 309, the lower mold spring guide columns 308 are tightened to put the two lower modules in a pre-tightened state.

[0065] Furthermore, as attached Figure 1 To Attachment Figure 4 The pushing mechanism includes a third lower module 106 , which has the same cross-sectional shape as the second lower die insert 305 and is an extension of the second lower die insert 305 . The initial position of the material rod 107 is installed in the third lower module 106 .

[0066] It also includes a push column 108 and a push column power device arranged at the feeding end to push the material rod 107 to move toward the discharging end. The push column power device includes a slider 109 fixedly connected to the push column. The slider 109 is installed on a slide rail 111 along the movement direction of the material rod 107. The slider 109 is fixedly connected to a belt 113 parallel to the slide rail 111. The belt 113 is connected to a push column motor 114. The push column motor 114 provides power for the push column 108 to move. A cover plate 112 is also provided at the feeding end to prevent the broken materials from jumping out. A slider stopper 110 fixed on the slide rail 111 is also provided at the tail end of the slider 109 to prevent the slider 109 from falling out.

[0067] Furthermore, as attached Figure 8 To Attachment Fig. 9 The sensing mechanism 103 includes a T-shaped elastic sensing column 401 and a sensing card plate 403. The elastic sensing column 401 is inserted into the mounting hole provided in the sensing card plate 403. A spring 402 is sleeved between the T-shaped head of the elastic sensing column 401 and the sensing card plate 403 to form a pre-tightening structure. The column passes through the sensing card plate 403 and is sleeved in the guide sleeve 404. The tail of the guide sleeve 404 is fixedly connected to the clamping ring 405. The guide sleeve 404 is provided with a through hole for the column of the elastic sensing column 401 to pass through. The size of the guide sleeve 404 is larger than the mounting hole, and the size of the clamping ring 405 is larger than the guide sleeve 404.

[0068] The tail side of the elastic sensing column 401 is provided with a position sensor 406 and the two are not connected. That is, the elastic sensing column 401 is clamped on both sides of the sensing clamp 403 by the guide sleeve 404 and the spring 402 in the initial position, the clamp ring 405 defines the position of the tail of the elastic sensing column 401, and the T-shaped head defines the position of the head of the elastic sensing column 401. In this embodiment, the sensing clamp 403 is U-shaped, and the elastic sensing column 401 and the position sensor 406 are respectively installed on its two long sides. The sensing mechanism 103 also includes a power device 407 connected thereto, and the power device 407 is a sensing cylinder, which drives the sensing mechanism to move as a whole.

[0069] Furthermore, as attached Figure 4 The material rod crusher of this embodiment also includes a bottom plate 105, and the elastic clamping mechanism, the pushing mechanism, the sensing mechanism 103 and the cutter 116 are all installed on the bottom plate 105. A drop opening 119 is provided on the bottom plate below the cutter 116 to receive the amorphous alloy fragments cut off by the cutter 116.

[0070] Combined with Figure 2 , 3 4. The working method of the rod crusher provided in this embodiment is as follows:

[0072] S2, turn on the induction cylinder 407 to drive the induction mechanism to move to the right ( Figure 2 ), turn on the push column motor 114 to drive the belt 113 to move, thereby driving the slider 109 to move to the left, and the slider 109 then drives the push column 108 to move to the left until the material rod 107 is pushed to move to the left;

[0073] S3, under the bidirectional push, the material rod 107 extends out of the discharge channel 117 and collides with the head of the elastic sensing column 401. The head of the elastic sensing column 401 is continuously compressed and rebounded by the material rod 117 to a distance H ( Fig. 9 ), the induction cylinder 407 is started to drive the induction mechanism to move back to the original position;

[0074] S4, the cutter punch 102 presses down to provide a downward pressure to the cutter punch connecting block 118, and the first upper die assembly 21 begins to elastically press downward, transmitting the force to the upper and lower die positioning guide pillars 115 to compress them downward until the upper die assembly 21 is pressed onto the lower die assembly 31 as a whole, and the downward pressure continues to be transmitted to the lower die assembly 31, and the lower die assembly begins to elastically press downward, so that the first lower die insert 304 and the second lower die insert 305 press the material rod 107 tightly between the two lower die inserts, and after pressing, the cutter 116 reaches the cutting position and cuts off the head of the material rod extending out of the discharge channel 117;

[0075] S5, the cutter punch 102 returns to its original position, and S2 to S4 are repeated.

[0076] It can be seen from the embodiments of the utility model that the material rod crusher provided by the utility model is used to process amorphous alloy material rods, and amorphous alloy scraps of uniform size can be obtained by cutting, and no further screening is required after crushing. The raw material recovery rate can reach more than 95%, and the recovery rate is high. The material rod crusher in the utility model is easy to disassemble and assemble, occupies a small area, has lower energy consumption and lower noise than traditional jaw crushers, saves time and effort in use, and has high process stability.

[0077] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
