Description

Technical Field

[0001] This application relates to the field of decommissioned rail steel processing technology, and in particular to a device and its working method for using decommissioned rail steel to forge bucket teeth. Background Technology

[0002] Rail steel, as the name suggests, is an alloy material used for train rails. It has good structural strength and surface hardness. After the steel used in the rails reaches its service life, it needs to be replaced. Most of the replaced steel is melted down and remanufactured into new rails, but this method is costly. More often, the rails are cut and shaped and directly used in the parts of engineering machinery, which reduces the cost of recycling.

[0003] One way to effectively utilize the high hardness of rail steel is to cut and forge it and then apply it to the bucket teeth of excavator buckets; for example... Figure 1 As shown, the rail steel includes the rail head A, rail web B, and rail base C. When cutting and processing it, as... Figure 2 As shown, the rail head A and rail web B need to be cut along the direction of the arrow in the diagram to form the required semi-finished bucket teeth D. Existing cutting equipment usually uses a flame cutter. During cutting: first, the workpiece is placed in a suitable position on the cutting platform, and then it is cut by the cutting device. After cutting, the cut semi-finished bucket teeth D and the remaining material need to be cleaned, and then a new workpiece is placed in for the next cutting, and so on. This process is repeated. This leads to the following problems: on the one hand, it is time-consuming and labor-intensive, and on the other hand, the loading and unloading process also affects the cutting efficiency. To address these issues, a device and its working method for forging bucket teeth from decommissioned rail steel are proposed to solve the above technical problems. Summary of the Invention

[0004] One objective of this application is to provide a device for forging bucket teeth from decommissioned rail steel that can improve cutting efficiency.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a device for forging bucket teeth from decommissioned rail steel, comprising a cutting table having two sets of cutting stations and two sets of placement stations; a cutting device mounted on the upper part of the cutting table; a driving mechanism mounted on the cutting table; and two sets of clamping structures adapted to clamp and fix the rail steel, and adapted to connect with the driving mechanism; during the cutting of the rail steel, one set of rail steel is located in one set of the cutting stations, and the other set of rail steel is located in one set of the placement stations; after the rail steel is cut, the driving mechanism is adapted to drive the rail steel located in the cutting station to move to the other set of the placement stations, and simultaneously, the driving mechanism is also adapted to drive the rail steel located in the placement station to move to the other set of the cutting stations.

[0006] Preferably, the driving mechanism includes a driving device, two sets of lead screws, and two sets of moving blocks. The lead screws are vertically rotatably mounted on the cutting table. The driving device is mounted on the cutting table and its output end is adapted to connect with the lead screw. The moving blocks slide vertically on the cutting table and are threadedly engaged with the corresponding lead screws. The clamping structure is mounted on the moving blocks. The driving device is adapted to drive the lead screws to rotate, thereby causing the two sets of moving blocks to move relative to or away from each other, so that the rail steel moves alternately between the cutting station and the placement station.

[0007] Preferably, the clamping structure includes a telescopic member, a drive structure, and a clamp for clamping the rail steel. The telescopic member is mounted on the moving block, the clamp is mounted on the movable end of the telescopic member, and the drive structure is mounted on the moving block and cooperates with the telescopic member. When the rail steel is located at the cutting station, the telescopic member is in a shortened state. When the rail steel moves down to the placement station, the drive structure is adapted to cooperate with the lower end face of the cutting table, thereby driving the movable end of the telescopic member to move and extend, so that the rail steel moves towards the outside of the cutting table.

[0008] Preferably, the drive structure includes a hinge rod and a movable block. The movable block is vertically slidably mounted on the bottom end of the moving block via an elastic element. The two ends of the hinge rod are respectively hinged to the movable block and the movable end of the telescopic member. When the moving block is adapted to drive the movable block to abut against the lower end face of the cutting table, the hinge rod is adapted to drive the movable end of the telescopic member to move and extend.

[0009] Preferably, the drive structure includes an elastic airbag, which is installed at the bottom of the moving block and communicates with the telescopic member; when the moving block is adapted to drive the airbag to abut against the lower end face of the cutting table, the airbag is adapted to deform and thus push the movable end of the telescopic member to move and extend by compressed air.

[0010] Preferably, the equipment for forging bucket teeth from the decommissioned rail steel further includes a receiving box, which is elastically slidably disposed on the cutting table; when the rail steel moves up to the cutting station, the moving block is adapted to move the receiving box by a second driving structure until the receiving box moves below the cutting station.

[0011] Preferably, the second drive structure includes a second airbag and a telescopic rod. The telescopic rod is installed on the cutting table and its movable end is connected to the receiving box. The second airbag is installed on the cutting table, located above the moving block, and communicates with the telescopic rod. The moving block is adapted to move upward and abut against the second airbag. The second airbag is adapted to deform and thus push the movable end of the telescopic rod to move and extend by compressed air, so that the receiving box moves below the cutting station.

[0012] Preferably, one end of the receiving box is provided with an opening, and the bottom end of the receiving box is inclined towards the opening, so that the semi-finished bucket teeth can slide out in the direction of the opening.

[0013] Preferably, the bottom of the receiving box is provided with a rolling component, which is adapted to change the sliding friction between the semi-finished bucket teeth and the bottom of the receiving box into rolling friction.

[0014] The present invention also provides a method for using equipment for forging bucket teeth from decommissioned rail steel, the method comprising the following steps:

[0015] S1: Place the rail steel to be cut into one of the lower sets of clamps, and then start the drive mechanism to move the clamps up to the corresponding cutting position; at the same time, the original upper set of clamps will move down to the corresponding placement position, at which point other rail steel to be cut can be placed into the clamps.

[0016] S2: When the rail steel at the placement station below moves up to the corresponding cutting station, the receiving box can be moved below the cutting station by the second drive structure. At this time, the cutting device is started to cut the rail steel, and the cut bucket tooth semi-finished product will fall into the receiving box for collection.

[0017] S3: After the rail steel is cut, the drive mechanism is restarted. The drive mechanism will drive the cut rail steel to move down to the corresponding placement station. At the same time, the clamp with the rail steel placed below will move up to the corresponding cutting station for cutting, thereby realizing dual-station cutting.

[0018] S4: When the cut rail steel moves down to the corresponding placement station, the drive structure can extend the lowered clamp outwards from the cutting table, making it easier to remove the cut material and then place a new rail steel to be cut; then repeat the above steps.

[0019] Compared with the prior art, the beneficial effects of this application are as follows:

[0020] This invention employs a dual-station cutting method, where the stations can be alternated after each cut. This reduces the waiting time for the cutting equipment, enabling continuous cutting, reducing labor intensity, achieving semi-automatic cutting, and greatly improving cutting efficiency.

[0035] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0036] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0037] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0038] One preferred embodiment of this application, such as Figures 1 to 13As shown, a device for forging bucket teeth from decommissioned rail steel includes a cutting table 2; a cutting device 1 installed on the cutting table 2, wherein the cutting device 1 is a flame cutter, which is existing technology and will not be described in detail; a drive mechanism 4 installed on the cutting table 2; and a clamping structure 3, which can clamp and fix the rail steel. There are two sets of clamping structures 3, and both sets of clamping structures 3 are connected to the drive mechanism 4.

[0039] Specifically, two sets of cutting stations are symmetrically arranged on the cutting table 2, and two sets of placement stations are symmetrically arranged below the cutting stations on the cutting table 2. It can be understood that when the rail steel is located at the cutting station, the cutting device 1 can perform cutting operations on the rail steel; when the rail steel is located at the placement station, the rail steel to be cut can be placed into the clamping structure 3 for clamping and fixing, or the cut rail steel can be taken out from the clamping structure 3.

[0040] When cutting the rail steel, the rail steel to be cut is placed on both sets of clamping structures 3. One set of rail steel is located in one set of cutting stations, and the other set of rail steel is located in one set of placement stations. That is, the two sets of placed rail steel are located in different stations. At this time, the rail steel located in the cutting station can be cut by the cutting device 1. After the rail steel located in the cutting station is cut, the drive mechanism 4 is started. The drive mechanism 4 can drive the rail steel located in the cutting station to move to another set of placement stations. At the same time, the drive mechanism 4 can also drive the rail steel located in the placement station to move to another set of cutting stations.

[0041] Therefore, cutting device 1 can cut the rail steel at another set of cutting stations, and the cut rail steel will be placed at another set of placement stations. It can be understood that during the time that cutting device 1 is cutting the rail steel at the other set of cutting stations, the workers can remove the remaining rail steel from the other set of placement stations and then put in new rail steel to be cut. This process is repeated, that is, through dual-station cutting, continuous cutting of rail steel is achieved, which greatly reduces the workload of the workers, saves more time and effort, and also greatly improves cutting efficiency.

[0042] In this embodiment, as Figure 6 and Figure 7As shown in the figure, the driving mechanism 4 includes a driving device, two sets of lead screws 41 and two sets of moving blocks 42. The cutting table 2 includes an upper table 21, a lower table 22 and a fixing frame 23. The upper table 21 is fixedly installed above the lower table 22 through columns. The fixing frame 23 is in a "冂" - shaped structure and is fixedly installed at the top of the lower table 22. A notch 13 is penetrated through the top of the upper table 21, which is to facilitate the rail steel to pass through the notch 13 or the cutting device 1 to pass through the notch 13, thus facilitating the cutting operation. The two sets of lead screws 41 are symmetrically and vertically rotatably installed between the fixing frame 23 and the lower table 22. Symmetrically distributed guide rods 7 are also fixedly installed between the fixing frame 23 and the lower table 22. The two sets of moving blocks 42 are respectively slidably arranged outside the two sets of guide rods 7, and the two sets of moving blocks 42 are respectively in threaded cooperation with the two sets of lead screws 41. The clamping structure 3 is installed on the moving blocks 42. The driving device (not shown in the figure) can be installed inside the lower table 22, and the output end of the driving device is connected to the lead screw 41.

[0043] To facilitate the understanding of the working mode of the driving mechanism 4, the following describes its working principle:

[0044] As Figure 6 shown in the figure, when a set of rail steel is at the upper cutting station, at this time the other set of rail steel is at the lower placing station; that is, at this time the moving block 42 at the cutting station is at the upper position corresponding to the lead screw 41, and the moving block 42 at the placing station is at the lower position corresponding to the lead screw 41; at this time, start the driving device, and the driving device can drive the two sets of lead screws to rotate simultaneously. The moving block 42 above the lead screw 41 will move downward, and the moving block 42 below the lead screw 41 will move upward, that is, the two moving blocks 42 move relatively. When the two moving blocks 42 move relatively, they will be misaligned. At this time, the two moving blocks 42 will continue to move away from each other until: the rail steel originally at the cutting station moves to the placing station, and the rail steel originally at the placing station moves to the cutting station, realizing the alternating movement of the cutting station and the placing station.

[0045] It should be noted that the driving device is common knowledge known to those skilled in the art, and can be a motor, a rotary cylinder or a rotary hydraulic cylinder, etc.

[0046] It should be further noted that the driving device can adopt two motors with forward and reverse functions to drive the two sets of lead screws 41 to rotate simultaneously; if there is one motor, at this time the two sets of lead screws 41 can be driven to rotate simultaneously through belt drive, chain drive or gear drive; the up and down movement of the moving block 42 is realized by the forward and reverse rotation of the lead screw 41.

[0047] Since the moving block 42 can only move up and down to exchange the cutting station and the placement station of the rail steel, the following problem arises: when the rail steel moves down to the placement station, it is necessary to pick up and put down the material, but the upper platform 21 above will hinder the picking up and putting down of the material, which is inconvenient.

[0048] In this embodiment, as Figure 6 and Figure 7 As shown, the clamping structure 3 includes a telescopic member 32, a drive structure 33, and a clamp 31. The drive structure 33 is installed on the moving block 42 and cooperates with the telescopic member 32. The telescopic member 32 is fixedly installed on the side of the moving block 42. The length of the telescopic member 32 can be freely extended and retracted. The clamp 31 is installed on the movable end of the telescopic member 32. The clamp 31 is a sleeve that fits the rail base C, that is, the rail base C of the rail steel can be inserted into the clamp 31 for clamping and fixing. This allows the rail head A and the rail web B to be placed horizontally, which is simple and convenient.

[0049] Specifically, such as Figure 6 As shown, when the left-side rail is at the cutting station, the telescopic component 32 is in a shortened state. When the rail moves down to the placement station via the drive mechanism 4, the drive mechanism 33 engages with the lower end face (lower platform 22) of the cutting table 2, thereby allowing the movable end of the telescopic component 32 to extend. This allows the rail to move outward from the cutting table 2, ideally extending beyond the cutting table 2, meaning the rail and the cutting table 2 are misaligned. This facilitates the loading and unloading of the rail, greatly improving convenience.

[0050] It should be noted that, as Figure 6 and Figure 7 As shown, the telescopic component 32 includes a fixed cylinder 321 and a movable plate 322. The movable plate 322 has an L-shaped structure, and the sleeve 31 is installed at the vertical end of the movable plate 322. The fixed cylinder 321 is fixedly installed on the side of the movable block 42, and the movable plate 322 is slidably disposed inside the fixed cylinder 321. The drive structure 33 has various structural forms, including but not limited to the following two:

[0051] Structure 1: such as Figure 9 As shown, the drive structure 33 includes a hinge rod 331 and a movable block 332. The movable block 332 can be vertically slidably disposed outside the guide rod 7 and located below the moving block 42. The movable block 332 and the moving block 42 can be connected by a spring 9. One end of the hinge rod 331 is hinged to the movable block 332, and the other end of the hinge rod 331 is hinged to the movable end (movable plate 322) of the telescopic member 32.

[0052] Under the action of spring 9, the movable block 332 and the hinge rod 331 can make the horizontal end of the movable plate 322 insert into the fixed cylinder 321, that is, the telescopic member 32 is in a shortened state. When the movable block 42 moves down a certain distance, the movable plate 322 will abut against the lower end face (lower platform 22) of the cutting table 2. When it continues to move down, the hinge rod 331 will be squeezed, which will cause the movable plate 322 to move and extend, that is, it can extend out of the cutting table 2, which will facilitate the picking and putting of materials.

[0053] Structure 2: such as Figure 10 As shown, the drive structure 33 includes an elastic airbag 333, that is, a spring is installed inside the airbag 333. When the airbag 333 is compressed by an external force, it will deform. When the external force disappears, the airbag 333 can restore its deformation. The airbag 333 is fixedly installed at the bottom of the moving block 42, and the airbag 333 can be connected to the fixed cylinder 321 of the telescopic component 32 through an air pipe or air channel. At this time, the moving plate 322 and the fixed cylinder 321 are in a sealed sliding state.

[0054] Under the action of airbag 333, the horizontal end of the movable plate 322 can be inserted into the fixed cylinder 321, that is, the telescopic part 32 is in a shortened state at this time; when the moving block 42 moves down a certain distance, the airbag 333 will abut against the lower end face (lower platform 22) of the cutting table 2. When it continues to move down, the airbag 333 will be compressed and deformed. At this time, the compressed air will enter the fixed cylinder 321, thereby pushing the movable plate 322 to move and extend, that is, it can extend out of the cutting table 2, thus facilitating the loading and unloading of materials.

[0055] To facilitate better repositioning of the movable plate 322, the movable plate 322 can also be slidably mounted on the fixed cylinder 321 via a spring.

[0056] It should be noted that both Structure 1 and Structure 2 can meet the actual needs, and those skilled in the art can use them according to the actual situation; however, using Structure 1 allows the hinge rod 331 to play a certain supporting role during the extension and retraction of the telescopic member 32, resulting in better stability.

[0057] One preferred embodiment of this application:

[0058] Since the cutting table 2 is equipped with a slot 13, the cut bucket tooth semi-finished product D will fall into the slot 13. Therefore, the equipment for forging bucket teeth from decommissioned rail steel also includes a receiving box 5. The receiving box 5 can collect the cut bucket tooth semi-finished product D. That is, the receiving box 5 should be below the corresponding position when the rail steel is cut. However, since the rail steel moves up and down to alternate the work positions, the receiving box 5 will interfere with the movement of the rail steel when it moves up and down. Therefore, the receiving box 5 needs to ensure the collection of materials while not interfering with the alternation of work positions.

[0059] In this embodiment, as Figure 11 and Figure 12 As shown, the receiving box 5 is slidably mounted on the fixed frame 23 of the cutting table 2, and the receiving box 5 and the fixed frame 23 are connected by a spring 10. Under the action of the spring 10, the receiving box 5 is located in the middle position of the slot 13. At this time, the receiving box 5, the two sets of cutting stations and the two sets of placement stations are misaligned, and will not interfere with the movement of the stations.

[0060] When the track steel moves upward to the cutting station, the moving block 42 can use the drive structure 2 8 to make the receiving box 5 move horizontally towards the cutting station until the receiving box 5 moves below the cutting station. The upward movement of the track steel and the movement of the receiving box 5 will not interfere with each other. At this time, there is a certain height difference between the receiving box 5 and the track steel, which can reduce the damage to the receiving box 5 during flame cutting. Similarly, when the track steel moves downward to change stations, the receiving box 5 will move and reset first under the action of the drive structure 2 8 and the spring 2 10, so as not to interfere with the downward movement of the track steel.

[0061] Specifically, as shown in the figure Figure 11 and Figure 12 As shown, the second drive structure 8 includes a second airbag 81 and a telescopic rod 82. The telescopic rod 82 is fixedly installed on the side of the fixed frame 23 on the cutting table 2, and the movable end of the telescopic rod 82 is connected to the receiving box 5. The second airbag 81 is installed on the lower end face of the fixed frame 23 on the cutting table 2. There are two airbags 81 and two telescopic rods 82, which are symmetrically distributed, that is, they correspond to two cutting positions respectively. The second airbag 81 and the corresponding telescopic rod 82 are connected through an air pipe or an air channel.

[0062] When the moving block 42 moves the rail steel to the cutting station, after moving a certain distance, the moving block 42 will abut against the corresponding airbag 81. Continuing to move upward will compress the airbag 81, causing it to deform and then push the telescopic rod 82 to extend via compressed air. This allows the receiving box 5 to move to a position below the cutting station, where it collects the cut bucket teeth semi-finished product D. After cutting, when the rail steel needs to be moved down to the corresponding placement position, the moving block 42 will first separate from the airbag 81, reducing and eventually eliminating the compressive force of the airbag 81. Therefore, the receiving box 5 will reset under the action of the spring 10, preventing interference with the downward movement of the rail steel. In other words, when the rail steel moves to the cutting station, the receiving box 5 will move to a position below the cutting station under the action of the drive structure 8 to receive the material, without interfering with the vertical movement of the rail steel, thus improving convenience.

[0063] It should be noted that, in order to improve the compactness and rationality of the installation, the telescopic rod 82 can be a pneumatic bamboo-joint type telescopic rod 82, and the spring 2 10 can be two sets and symmetrically arranged.

[0064] In this embodiment, as Figure 13 As shown, an opening 12 can be provided at one end of the receiving box 5, and the bottom of the receiving box 5 is inclined towards the opening 12. In this way, when the cut bucket tooth semi-finished product D is discharged in the direction of the opening 12 under the action of gravity, a receiving box 6 can be placed below the opening 12 to collect the bucket tooth semi-finished product D in a concentrated manner.

[0065] Since the semi-finished bucket teeth D slides down relative to the receiving box 5, if the tilt angle of the receiving box 5 is too small, the semi-finished bucket teeth D may accumulate in the receiving box 5 under the action of friction. If the tilt angle of the receiving box 5 is too large, the receiving box 5 needs to have a certain height, which will increase the installation space. Therefore, a rolling component 11 can be set at the bottom of the receiving box 5. The rolling component 11 can change the original sliding friction between the semi-finished bucket teeth D and the bottom of the receiving box 5 into rolling friction, thereby greatly reducing the friction and improving the feeding effect.

[0066] The rolling assembly 11 can be multiple sets of balls, which are equidistantly mounted at the bottom of the receiving box 5; the rolling assembly 11 can also be multiple sets of rotating rollers, the length of which is adapted to the width of the receiving box 5, and the rotating rollers are equidistantly mounted at the bottom of the receiving box 5 along the length of the receiving box 5.

[0067] The present invention also provides a method for operating a device for forging bucket teeth using decommissioned rail steel, the method comprising the following steps:

[0068] S1: Place the rail steel to be cut into the lower set of clamps 31, and then start the drive mechanism 4, so that the clamps 31 can be moved up to the corresponding cutting station; at the same time, the original upper set of clamps 31 will be moved down to the corresponding placement station, at which time other rail steel to be cut can be placed in the clamps 31.

[0069] In this step, such as Figure 3 As shown, it is best to have two people working together, with two people standing on either side of the cutting table 2. This is because the cutting station and the placement station are vertically and symmetrically located on both sides of the cutting equipment. One person can control the vertically and vertically corresponding cutting station and placement station, which allows for better operation. Of course, one person can also operate the equipment, but they will need to move back and forth between the two sides of the cutting equipment.

[0070] S2: When the track steel placed at the lower station moves up to the corresponding cutting station, the receiving box 5 can be moved to the lower part of the station to be cut by the drive structure 2 8. At this time, the cutting device is started to cut the track steel, and the cut bucket tooth semi-finished product D will fall into the receiving box 5 for collection.

[0071] In this step, workers can place a receiving box 6 below the opening 12 of the receiving box 5 to collect the semi-finished bucket teeth D, facilitating subsequent processing and transportation. At the same time, the receiving box 6 not only reduces the scattering of the semi-finished bucket teeth D but also avoids a messy production site, thereby improving production efficiency.

[0072] S3: After the rail steel is cut, the drive mechanism 4 is started again. The drive mechanism 4 will drive the cut rail steel to move down to the corresponding placement station. At the same time, the clamp 31 with the rail steel placed below will move up to the corresponding cutting station for cutting, thus realizing dual-station cutting.

[0073] In this step, it is important to note that during the alternation of workstations, the receiving box 5 will not interfere with the up-and-down movement of the clamp 31, because the movement paths of the receiving box 5 and the clamp 31 are independent of each other.

[0074] S4: When the cut rail steel moves down to the corresponding placement station, the moving sleeve 31 can extend outward to the outside of the cutting table 2 under the action of the drive structure 33. This makes it easy to remove the cut material and then put in the new rail steel to be cut; then repeat the above steps.

[0075] In summary, existing flame cutting equipment involves placing the workpiece on a worktable and then automatically cutting it. After cutting, workers need to remove the cut product and any remaining material from the worktable before placing a new workpiece for the next cut. This process is inefficient and labor-intensive. In contrast, this invention employs a dual-station cutting system, allowing for station switching after each cut. This reduces the waiting time for the cutting equipment, enabling continuous cutting and improving efficiency. Furthermore, the cut product can be automatically collected, and the height for picking up and placing the workpiece is lowered, achieving semi-automatic cutting and reducing labor. On the other hand, existing technologies use a grid-type worktable, where the workpiece needs to be placed on it. Due to the unique steel structure of the rails, the different heights of the rail head A and rail bottom C make horizontal placement difficult. Based on the unique structure of the rail steel, the present invention designs a unique jacket 31 structure, which can quickly clamp and fix the rail steel to achieve suspended cutting. Moreover, the cutting table 2 is designed with a through-hole through slot 13, so the flame cutting machine will not cause damage to the cutting table 2 during operation, thereby extending the service life of the cutting table 2.

[0076] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments.
