Description

Technical Field

[0001] This invention relates to the field of tram track processing equipment technology, specifically to a special-shaped transition rail forming equipment for connecting grooved rails and I-beam rails. Background Technology

[0002] Tram mainlines generally use embedded grooved rails, while I-beam rails are used in the depot. At the entrance of the depot, irregularly shaped transition rails need to be installed to achieve a smooth transition between the two types of rails with different cross-sections. The machining quality of the R-angle of the working side of the transition groove of the irregularly shaped transition rail directly affects the smoothness of the wheelset passage. Discontinuous R-angle profiles, steps, sharp edges, overcutting and other defects will aggravate wheel wear and easily cause wheel-rail impact, reducing the overall service life of the track components.

[0003] Currently, the R-angle grinding of the working edge of the transition groove of irregular transition rails in China is mostly done manually by operators using handheld grinding machines. This processing method has many practical shortcomings.

[0004] First, manual hand-held grinding operations are inefficient. A single hand-held grinding tool can only process a localized area of ​​a single workpiece at a time. The three processes of rough grinding, medium grinding, and fine grinding require operators to change abrasives and complete them in batches, making it impossible to perform multi-process parallel processing. Due to the limitations of human operation, grinding a single workpiece takes a long time, resulting in insufficient production capacity for mass production tasks, making it difficult to meet the supply needs of large quantities of irregularly shaped transition rails for tram projects.

[0005] Secondly, processing quality is greatly affected by human factors, resulting in poor product consistency. The feed pressure, grinding belt contact angle, and radius (R) contour during grinding rely entirely on the operator's practical experience for control. Significant differences in processing results can occur between different operators, and even between different shifts of the same operator. During grinding, the R-angle contour constantly changes, and handheld tools struggle to dynamically adapt to these changes, easily leading to quality defects such as uneven R-angle transitions, localized overcutting, residual steps, and sharp edges. This necessitates extensive rework and grinding, resulting in a high scrap rate and difficulty in ensuring product quality stability.

[0006] Furthermore, handheld grinding is physically demanding and operates in a harsh environment. The grinding process continuously generates large amounts of metal shavings and fumes, which fly everywhere. On one hand, these shavings can easily get stuck in the grooves of irregularly shaped transition rails, scratching the surface of the already machined workpiece and causing secondary damage. On the other hand, the fumes and metal dust permeating the surrounding area can harm the respiratory system of operators over time, posing a high occupational health risk. Additionally, the flying shavings scattered on equipment and the floor lack a centralized collection system, resulting in a significant amount of on-site cleanup work afterward.

[0007] There are also a few general-purpose belt grinding equipment on the market, but most general-purpose grinding equipment is designed for conventional flat and outer cylindrical workpieces. It is difficult to adapt to the special spatial structure of the concave transition groove of irregular transition rails, and it cannot achieve adaptive contour grinding of the working edge R angle in the groove; it also cannot achieve simultaneous clamping and processing of two workpieces and simultaneous grinding of multiple grinding processes along the length of the workpiece. Therefore, it cannot be directly used for mass grinding production of irregular transition rails. Summary of the Invention

[0008] The purpose of this invention is to overcome the problems of low processing efficiency, inconsistent grinding quality due to manual hand-held grinding machines, poor working environment, and health hazards to operators caused by grinding dust and fumes in existing irregular transition rails.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: A forming device for irregularly shaped transition rails connecting grooved rails and I-beam rails, comprising: Installation platform; A pair of grinding mechanisms are symmetrically arranged on the left and right sides of the mounting platform; each grinding mechanism includes three sets of grinding components for coarse grinding, medium grinding and fine grinding respectively, and a drive component for driving the three sets of grinding components. The grinding assembly includes a mounting tube, a grinding belt, and a motor. The mounting tube has a Y-shaped structure, with a first extrusion roller slidably mounted inside its outer and lower branches, and a second extrusion roller slidably mounted inside its inner branch. The grinding belt is sleeved on the outside of the mounting tube. The motor drives the second extrusion roller to move, pushing the two first extrusion rollers that are in contact with it to separate from each other. The two first extrusion rollers cooperate with the second extrusion roller to fit the grinding belt into the working edge of the transition groove of the irregular transition rail according to the arc matching the preset process, thereby adapting to the R angle change of the working edge in different grinding stages. The drive assembly includes a second motor, which drives three grinding belts corresponding to the rough grinding, medium grinding and fine grinding processes in the same grinding mechanism to operate synchronously through a friction transmission system. A moving mechanism, located in the middle of the mounting platform, includes a rodless cylinder, a dual-axis cylinder, and a pair of linkage frames. The grinding mechanism is correspondingly mounted on the linkage frames. The dual-axis cylinder drives the pair of linkage frames to move in opposite directions or back-to-back through a hinge structure. When the pair of linkage frames move in opposite directions, they cause the grinding mechanisms on both sides to move closer together, thus separating the grinding strip from the corresponding working edge. When the pair of linkage frames move back-to-back, they cause the grinding mechanisms on both sides to move away from each other, thus making the grinding strip contact the corresponding working edge. The rodless cylinder drives the dual-axis cylinder and the pair of linkage frames to move in the front-to-back direction, thereby driving the grinding mechanism to feed along the extension direction of the transition groove, realizing the synchronous processing of the two irregular transition rails on the left and right sides. Moreover, the single irregular transition rail simultaneously and in parallel completes three R-angle grinding processes—rough grinding, medium grinding, and fine grinding—in different sections along its length.

[0010] Preferably, a set of positioning plates is provided on each of the left and right sides of the mounting platform, and each set of positioning plates is used to limit and position the corresponding single irregular transition rail from the four corners.

[0011] Preferably, the mounting platform has a mounting groove in the middle; A mounting plate is provided below the mounting slot, and the mounting plate is fixed to the mounting platform by a number of mounting posts; The rodless cylinder is horizontally mounted on the mounting plate. A U-shaped sliding frame is mounted on the pneumatic slider of the rodless cylinder. Mounting strips are symmetrically mounted on the front and rear ends of the sliding frame. A linear guide rail is horizontally connected to the mounting strip, and a pair of sliding blocks are slidably fitted on the linear guide rail. Each sliding block is equipped with a sliding plate. The dual-axis cylinders are symmetrically installed on the front and rear sides of the sliding frame. The piston rod of the dual-axis cylinder is connected to a hinge seat upward. The hinge seat is hinged to the left and right sliding plates respectively through a pair of hinge bars. The two linkage frames are respectively connected between the front and rear sliding plates.

[0012] Preferably, each of the hinge seats is equipped with a support bar, and a chip blowing pipe is installed between the front and rear support bars. Two rows of chip blowing holes are distributed on the left and right sides of the chip blowing pipe, and air supply pipes are installed at the front and rear ends of the chip blowing pipe respectively.

[0013] Preferably, a chip collection box is detachably connected inside the sliding frame, and handles are symmetrically installed on the left and right sides of the chip collection box.

[0014] Preferably, the outer branch pipe and the lower branch pipe of the mounting pipe are respectively provided with a sliding groove, and the two ends of the extrusion roller are correspondingly slidably connected in the sliding groove. The inner branch of the mounting pipe has a sliding groove 2 on its side wall, and the two ends of the extrusion roller 2 are slidably connected to the sliding groove 2. Sliding plates are provided on the outer side of the first extrusion roller in the outer branch pipe and on the lower side of the first extrusion roller in the lower branch pipe, and a helical spring is provided between the sliding plate and the corresponding end of the installation pipe. The inner branch of the mounting pipe has an installation port, and a mounting plate is fixedly connected inside the installation port. The first motor is mounted on the mounting plate, and the output shaft of the first motor is threadedly connected to the second extrusion roller.

[0015] Preferably, each of the sliding plates is equipped with a second motor, and the output shafts of the two second motors are coaxially fixed to a mounting shaft via a coupling. Three drive rollers are mounted on the mounting shaft, and the three drive rollers are in frictional contact with the three grinding belts corresponding to the rough grinding, medium grinding, and fine grinding processes.

[0016] Preferably, the sliding plate is symmetrically rotatably supported by a pair of limiting rollers on the side near the second extrusion roller, and the pair of limiting rollers abut against the corresponding second extrusion roller.

[0017] Preferably, the outer branch pipe end and the lower branch pipe end of the mounting pipe are respectively equipped with mounting seats, and a driven roller is rotatably supported on the mounting seat; The inner branch pipe end of the installation pipe is rounded. The grinding belt is sleeved on the outer and lower driven rollers and the inner end of the mounting tube.

[0018] Compared with the prior art, the present invention has the following advantages: 1. This invention significantly improves processing efficiency by replacing manual hand-held grinding. It features a pair of symmetrical grinding mechanisms that can simultaneously clamp and process two irregularly shaped transition rails. The drive assembly synchronously rotates three grinding belts corresponding to rough grinding, medium grinding, and fine grinding. Combined with the feed motion of the moving mechanism, three round-angle grinding processes are completed simultaneously and in parallel in different sections along the length of a single irregularly shaped transition rail. This eliminates the need for manual, step-by-step grinding, saves time during process transitions, and greatly increases batch processing capacity.

[0019] 2. The grinding arc is adaptively adjustable, resulting in high consistency in workpiece forming quality. The motor inside the Y-shaped mounting tube drives the two extrusion rollers to move, which in turn pushes the two extrusion rollers to separate. Combined with the helical spring for reset, this allows for flexible adjustment of the grinding belt's contact arc, adapting to the changing R-angle contours of the transition groove working edge at different stages of rough, medium, and fine grinding. This eliminates reliance on the operator's grinding experience, effectively avoiding overcutting and step defects, ensuring a continuous and smooth R-angle profile, and resulting in good workpiece processing consistency.

[0020] 3. Grinding chip blowing - centralized collection, improving the working environment. Compressed air is ejected from the chip blowing holes of the chip blowing pipe to promptly blow grinding chips away from the processing area; the sliding frame is equipped with a detachable chip collection box to centrally collect grinding chips, reducing the spread of debris and dust on site, reducing the risk of grinding chips scratching workpieces and jamming mechanisms, reducing on-site cleaning workload, improving the working environment, and protecting the health of operators.

Detailed Implementation

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] like Figures 1 to 11 As shown, this embodiment provides a forming device for irregular transition rails used in connecting grooved rails and I-beam rails, comprising: Mounting platform 10; A pair of grinding mechanisms 30 are symmetrically arranged on the left and right sides of the mounting platform 10; each of the grinding mechanisms 30 includes three sets of grinding components for coarse grinding, medium grinding and fine grinding respectively, and a drive component for driving the three sets of grinding components. The grinding assembly includes a mounting tube 301, a grinding belt 313, and a motor 307. The mounting tube 301 has a Y-shaped structure, with a first extrusion roller 302 slidably mounted inside its outer and lower branches, and a second extrusion roller 308 slidably mounted inside its inner branch. The grinding belt 313 is sleeved on the outside of the mounting tube 301. The motor 307 drives the second extrusion roller 308 to move, pushing the two extrusion rollers 302 that are in contact with it to separate from each other. The two extrusion rollers 302 cooperate with the second extrusion roller 308 to fit the grinding belt 313 into the working edge 40b of the transition groove 40a of the irregular transition rail 40 according to the arc matching the preset process, so as to adapt to the R angle change of the working edge 40b in different grinding stages. The drive assembly includes a second motor 309, which drives three grinding belts 313 corresponding to the rough grinding, medium grinding and fine grinding processes within the same grinding mechanism 30 to operate synchronously through a friction transmission system. The moving mechanism 20 is located in the middle of the mounting platform 10. The moving mechanism 20 includes a rodless cylinder 203, a dual-axis cylinder 209, and a pair of linkage frames 212. The grinding mechanism 30 is correspondingly mounted on the linkage frames 212. The dual-axis cylinder 209 drives the pair of linkage frames 212 to move left and right towards each other or back to back through a hinge structure. When the pair of linkage frames 212 move towards each other, they drive the two grinding mechanisms 30 to move closer to each other, thereby disengaging the grinding belt 313 from the corresponding working edge 40b. When the moving frame 212 moves away from each other, it drives the two grinding mechanisms 30 to move away from each other, so that the grinding belt 313 can contact the corresponding working edge 40b. The rodless cylinder 203 drives the dual-axis cylinder 209 to move along the front and back direction together with a pair of linkage frames 212, thereby driving the grinding mechanism 30 to feed along the extension direction of the transition groove 40a, so as to realize the synchronous processing of the two irregular transition rails 40 on the left and right sides, and the single irregular transition rail 40 can simultaneously and in parallel complete the three R-angle grinding processes of rough grinding, medium grinding and fine grinding in different sections along the length direction.

[0035] This equipment is equipped with two grinding mechanisms 30 on the left and right sides, which can process two irregular transition rails 40 simultaneously. Relying on the cooperation of Y-shaped mounting tube 301, extrusion roller one 302 and extrusion roller two 308, the curvature of the grinding belt 313 can be adaptively adjusted to meet the grinding requirements of the R angle of the working edge 40b at different stages. The three grinding belts 313 are operated synchronously by motor two 309. With the help of the rodless cylinder 203, double-axis cylinder 209 and linkage frame 212 of the moving mechanism 20, rough grinding, medium grinding and fine grinding are carried out in parallel in different length sections of the workpiece, which greatly improves the grinding efficiency of the R angle of the working edge 40b of the transition groove 40a of the irregular transition rail 40.

[0036] In this embodiment, a set of positioning plates 101 are provided on each of the left and right sides of the mounting platform 10. Each set of positioning plates 101 is used to limit and position the corresponding single irregular transition rail 40 from the four corners.

[0037] The positioning plate 101 limits and positions the irregular transition rail 40 from the four corners, which can limit the displacement and shaking of the irregular transition rail 40 during the processing, and ensure the grinding position accuracy of the grinding belt 313 on the working edge 40b of the transition groove 40a.

[0038] In this embodiment, the mounting platform 10 has a mounting groove 10a in the middle; A mounting plate 201 is provided below the mounting groove 10a, and the mounting plate 201 is fixed to the mounting platform 10 by a plurality of mounting posts 202. The rodless cylinder 203 is horizontally mounted on the mounting plate 201. A U-shaped sliding frame 204 is mounted on the pneumatic slider of the rodless cylinder 203. Mounting strips 205 are symmetrically mounted on the front and rear ends of the sliding frame 204. A linear guide rail 206 is horizontally connected to the mounting strip 205. A pair of sliding blocks 207 are slidably fitted on the linear guide rail 206. Each sliding block 207 is equipped with a sliding plate 208. The dual-axis cylinder 209 is symmetrically installed on the front and rear sides of the sliding frame 204. The piston rod of the dual-axis cylinder 209 is connected upward to the hinge seat 210. The hinge seat 210 is hinged to the left and right sliding plates 208 respectively through a pair of hinge bars 211. The two linkage frames 212 are respectively connected between the front and rear sliding plates 208.

[0039] Mounting plate 201 and mounting column 202 provide a mounting base for rodless cylinder 203; linear guide rail 206 and sliding block 207 provide guidance for sliding plate 208; dual-axis cylinder 209, hinge seat 210 and hinge bar 211 form a hinge amplification transmission structure, which drives sliding plate 208 and linkage frame 212 to complete opening and closing actions, so as to realize stable contact and separation of grinding mechanism 30 from workpiece, and smooth and reliable motion transmission.

[0040] In this embodiment, each hinge seat 210 is equipped with a support bar 213, and a chip blowing pipe 214 is installed between the front and rear support bars 213. Two rows of chip blowing holes 214a are distributed on the left and right sides of the chip blowing pipe 214, and air supply pipes 215 are installed at the front and rear ends of the chip blowing pipe 214 respectively.

[0041] Air supply pipe 215 supplies air to chip blowing pipe 214, and compressed air is ejected from chip blowing hole 214a, which can promptly blow away the iron chips generated during grinding from the grinding processing area, preventing grinding chips from getting stuck in transition groove 40a or the gap of moving pair, and preventing scratches on the workpiece surface and jamming of the mechanism.

[0042] In this embodiment, a chip collection box 216 is detachably connected inside the sliding frame 204, and handles 217 are symmetrically installed on the left and right sides of the chip collection box 216.

[0043] The chip collection box 216 receives the grinding chips blown off by the chip blowing pipe 214; the chip collection box 216 is detachable and equipped with a handle 217, which makes it convenient for operators to collect, empty and clean the grinding chips, and keep the inside of the equipment clean.

[0044] In this embodiment, the side walls of the outer branch pipe and the lower branch pipe of the mounting pipe 301 are respectively provided with sliding grooves 301a, and the two ends of the extrusion roller 302 are correspondingly slidably connected in the sliding grooves 301a. The inner branch of the mounting pipe 301 has a sliding groove 301b on its side wall, and the two ends of the extrusion roller 308 are correspondingly slidably connected in the sliding groove 301b. Sliding plates 303 are provided on the outer side of the extrusion roller 302 in the outer branch pipe of the mounting tube 301 and on the lower side of the extrusion roller 302 in the lower branch pipe, and a helical spring 305 is provided between the sliding plate 303 and the corresponding end of the mounting tube 301. The inner branch of the mounting pipe 301 has a mounting port 301c, and a mounting plate 306 is fixedly connected inside the mounting port 301c. The motor 307 is mounted on the mounting plate 306, and the output shaft of the motor 307 is threadedly connected to the extrusion roller 308.

[0045] Sliding groove 1 301a and sliding groove 2 301b provide sliding guides for extrusion roller 1 302 and extrusion roller 2 308, respectively; helical spring 305 provides reset elastic force for extrusion roller 1 302; mounting plate 306 is set on mounting port 301c to realize reliable assembly of motor 1 307; motor 1 307 drives extrusion roller 2 308 to move linearly through thread, realizing the opening and resetting of extrusion roller 1 302, and flexibly adjusting the forming arc of grinding belt 313.

[0046] In this embodiment, a second motor 309 is installed on each of the sliding plates 208. The output shafts of the two second motors 309 are coaxially fixed to the mounting shaft 311 through the coupling 310. Three active rollers 312 are installed on the mounting shaft 311. The three active rollers 312 are in frictional contact with the three grinding belts 313 corresponding to the rough grinding, medium grinding and fine grinding processes.

[0047] The coupling 310 enables coaxial transmission of the mounting shaft 311. The motor 309 drives the mounting shaft 311 and the three drive rollers 312 to rotate synchronously. The friction transmission drives the three grinding belts 313 to operate synchronously, ensuring the consistency of speed in the rough grinding, medium grinding and fine grinding processes, and good stability in the grinding process.

[0048] In this embodiment, the sliding plate 303 is symmetrically rotatably supported on the side near the second extrusion roller 308, and the pair of limit rollers 304 abut against the corresponding second extrusion roller 308.

[0049] The limiting roller 304 rolls against the extrusion roller 308, converting the sliding friction between the extrusion roller 308 and the sliding plate 303 into rolling friction, reducing motion resistance, reducing component wear, and improving the opening response sensitivity of the extrusion roller 302.

[0050] In this embodiment, the outer branch pipe end and the lower branch pipe end of the mounting pipe 301 are respectively equipped with mounting bases 314, and the driven rollers 315 are rotatably supported on the mounting bases 314. The inner branch pipe end of the mounting pipe 301 is rounded. The grinding belt 313 is sleeved on the outer and lower driven rollers 315 and the inner end of the mounting tube 301.

[0051] Mounting base 314 provides rotational support for driven roller 315, which in turn guides and tensions the grinding belt 313. The end of the inner branch pipe of mounting tube 301 is rounded to prevent the sharp edges from cutting or wearing the grinding belt 313 and to extend the service life of the grinding belt 313.

[0052] The working principle of the drying device for producing corn seeds of the present invention will be described in detail below with reference to the accompanying drawings: During processing, two irregular transition rails 40 are placed on the left and right sides of the mounting table 10 respectively. Each set of positioning plates 101 limits and positions the corresponding irregular transition rails 40 from the four corners to complete the workpiece clamping. When the equipment is started, motor 2 309 drives the mounting shaft 311 and three drive rollers 312 to rotate through coupling 310, and drives the three grinding belts 313 to operate synchronously by friction transmission; motor 1 307 drives extrusion roller 2 308 to move in the inner branch tube of mounting tube 301. Extrusion roller 2 308 pushes two extrusion rollers 1 302 to overcome the elastic force of helical spring 305 and separate them, thereby adjusting the outer contour curvature of the grinding belt 313 to match the R angle dimension of the working edge 40b in the current grinding process.

[0053] The dual-axis cylinder 209 drives the hinge seat 210, which in turn drives the sliding plate 208 and the linkage frame 212 to move in opposite directions via the hinge bar 211, causing the grinding mechanism 30 to open outwards and the grinding belt 313 to contact the working edge 40b of the irregular transition rail 40. The rodless cylinder 203 drives the sliding frame 204 to move back and forth along the extension direction of the transition groove 40a. The three grinding belts 313 for rough grinding, medium grinding and fine grinding simultaneously carry out R-angle grinding operations in different length sections of the workpiece.

[0054] During the grinding process, the air supply pipe 215 supplies air to the chip blowing pipe 214, and the compressed air is ejected from the chip blowing hole 214a, blowing the iron chips generated during grinding into the chip collection box 216 inside the sliding frame 204. After the processing is completed, the dual-axis cylinder 209 drives the linkage frame 212 to move towards each other, the grinding mechanism 30 moves closer to each other, and the grinding belt 313 is separated from the workpiece. The chip collection box 216 can be pulled out as a whole to complete the chip dumping and cleaning.

[0055] Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not exhaustive. All modifications within the scope of this invention or its equivalents are included in this invention.
