Description

Technical Field

[0001] The present invention relates to the technical field of stamping processing equipment, and in particular to a U-shaped steel processing equipment and method for high-speed railways. Background Art

[0002] As one of the essential materials for high-speed rail construction, U-shaped steel needs to be processed through stamping metal processing during the production process to process U-shaped steel into specific parts or components required for high-speed rail construction. It is to process steel plates into specific parts or components required for high-speed rail construction.

[0003] In the existing steel stamping process, hook holes need to be opened in the steel in advance. First, they are used to position the subsequent punching holes. Second, the holes opened make it convenient for operators to grab the steel plates with hooks, making it convenient for steel to be transferred between different production equipment. However, before the steel is stamped, it is necessary to heat the steel to facilitate subsequent stamping operations, which makes the temperature of the steel very high. If the hook falls off, it will cause direct contact between the steel and the operator, causing the high-temperature steel to cause burns to the operator's skin. Summary of the Invention

The top surface of the stamping operation plate is provided with a top sliding groove that slides with the side resistance plates.

[0007] Preferably, a gear box B is provided at the bottom end of the stamping operation plate, the output end and the input end of the gear box B are both connected to the roller shaft, and a gear box A is provided on the side of the bottom surface of the stamping operation plate.

[0008] Preferably, the output end of the gearbox A is fixedly connected to the roller shaft, the bottom end of the output shaft of the gearbox A is fixedly connected to the input end of the gearbox B, the input end of the gearbox A is provided with a transmission shaft, and the bottom end of the transmission shaft is provided with a driven bevel gear.

[0009] Preferably, a hanger is provided on the bottom surface of the stamping operation plate, and an auxiliary power supply mechanism is rotatably provided on the hanger. A guide notch is provided on the hanger to provide a limiting guide for the spur rack. The auxiliary power supply mechanism includes a spring box and a spur gear rotatably arranged on the left and right sides of the hanger, and a pawl plate is provided on the spur gear. The teeth of the spur gear are meshed with the teeth of the spur rack, and a ratchet plate is rotatably provided in the middle of the bottom end of the hanger, which is matched with the pawl plate for unidirectional rotation.

[0010] Preferably, the ratchet disc is provided with a spring disc that rotates in conjunction with the spring barrel, and the spring disc is provided with a power storage spring that is fixedly connected to the inner side of the spring barrel.

[0011] Preferably, the mainspring box is provided with a driving shaft which passes through the mainspring disc, the ratchet disc, the pawl disc and the spur gear in sequence, and the end of the driving shaft is provided with a driving bevel gear which meshes with the driven bevel gear.

[0012] Preferably, a lock shaft is provided on the outer surface of the clockwork box, and magnets B with opposite magnetic poles are provided on the left and right sides of the lock shaft.

[0014] A method for using a U-shaped steel processing device for high-speed railways comprises the following steps: S1: The steel plate after heating treatment will be conveyed through the feeding roller group so that the steel plate can reach the top surface of the stamping seat; S2: When the steel plate reaches the top surface of the stamping seat, the end of the steel plate will be aligned with the top of the material blocking plate. The left and right positions of the steel plate can be adjusted by the rotation of the side adjustment screw, so that the stamping position of the steel plate will not be offset during the downward stamping process of the stamping die. S3: As the lifting seat moves downward, the spur rack drives the spur gear to rotate. The pawl and ratchet discs rotate in one direction, allowing the pawl disc to drive the ratchet disc to rotate, thereby causing the mainspring disc to rotate synchronously. At this time, the lock shaft is in the locking position of the lifting seat, restricting the rotation of the mainspring barrel, allowing the mainspring disc to drive the stored mainspring to tighten; S4: After the stamping process is completed, the formed steel is obtained, and then the jacking seat drives the stamping seat to push the formed steel upward until the top surfaces of the two ends of the stamping seat are flush with the top surface of the stamping operation plate. At this time, the meshing and matching effect between the spur rack and the spur gear will prevent the pawl plate from driving the ratchet plate to rotate; S5: When the top surfaces at both ends of the punching seat are flush with the top surface of the punching operation plate, the lock shaft will cooperate with the lifting seat to release its rotation lock on the barrel, so that the active bevel gear at the end of the active shaft will engage with the driven bevel gear, thereby allowing the gear sets inside gearbox A and gearbox B to rotate, synchronously driving the two active rollers to rotate in opposite directions at the same speed, so that the transmission chain belt can be adjusted in position, so that the push plate acts on the end surface of the formed steel to push the formed steel to the top surface of the unloading roller group, and the unloading roller group transports the formed steel to the next production process.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the setting of the unloading rack, loading roller group and pushing plate, the conveying function of the transmission chain belt and the anti-fall shaft seat can be used to push the stamped plates. There is no need to rely on manual hooks to grab the plates, and it avoids the situation of burns caused by position deviation caused by manual grabbing of high-temperature plates.

[0016] 2. By setting up the auxiliary force supply mechanism and utilizing the internal components of the auxiliary force supply mechanism and the rotational coordination between the auxiliary force supply mechanism and the spur rack, the plate can rotate and store force on the internal components of the auxiliary force supply mechanism during the stamping process. During the blanking process after the stamping of the plate is completed, the stored force can be released for use, and the auxiliary blanking operation of steel can be completed without adding precision control equipment and drive equipment.

[0017] 3. Through the setting of the side adjustment screw and the material blocking plate, the position of the sheet material conveyed to the top surface of the punching seat can be accurately controlled, and the punching position can be adjusted for different punching seats according to different sheets.

[0018] 4. Through the setting of the unloading rack, when the unloading rack is adjusted relative to the punching seat, the position of the material blocking plate can be adjusted synchronously, so that in the actual production operation process, it is only necessary to simply adjust the position of the plate in the left and right directions using the side adjustment screw and the side blocking plate, which makes the operation simple.

[0019] 5. The connection between the push plate and the anti-drop shaft seat is set up in a rotating manner. The two are connected, and a baffle is provided at the bottom of the anti-drop shaft seat. The top end can allow the push plate to rotate 75 degrees around the connecting axis of the two. Therefore, when the width of the plate is large during the stamping stage of the formed steel, the formed steel can lift the push plate upward to avoid the position of the push plate affecting the normal stamping operation of the formed steel.

[0020] In summary, the present invention overcomes the shortcomings of the existing technology. During the stamping process of metal plates, there is no need to manually transfer the position of the high-temperature plates to be processed through grabbing hooks, thereby avoiding the contact between the human body and the high-temperature plates during the transfer of the plates. It has high social use value and application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

The active roller 31 and the driven roller 32 are set with a transmission chain belt 33, and the transmission chain belt 33 is provided with an anti-falling shaft seat 331. The anti-falling shaft seat 331 is rotatably provided with a pushing plate 332 that pushes the formed steel 100 to move. The pushing plate 332 is relative to the anti-falling shaft seat 331 as shown in FIG. Figure 4 As shown in the position of , it can be rotated 75 degrees upward around the connecting axis between the two.

[0026] Specifically, refer to Figure 1-3 and Figure 11 , both sides of the unloading rack 102 are provided with a material blocking plate 1022, and the bottom surface of the material blocking plate 1022 is slidably fitted with the top surface of the stamping operation plate 1, and the outer end of the side slide groove 101 is provided with a locking screw 1011 for locking the relative position of the unloading rack 102 and the stamping operation plate 1. When stamping different lengths of formed steel 100, a corresponding type of stamping seat 2 can be installed on the top surface of the jacking seat 104. Before installation, the relative position between the unloading rack 102 and the stamping operation plate 1 needs to be adjusted according to the size of the stamping seat 2. During the adjustment process, the material blocking plate 1022 will also be adjusted in position synchronously, so that when the formed steel 100 is transported to the top surface of the stamping seat 2, it can resist the end face of the formed steel 100, thereby playing a role in end positioning.

[0027] Specifically, refer to Figure 3 The left and right ends of the top surface of the stamping operation plate 1 are threaded with side adjustment screws 4, and the ends of the side adjustment screws 4 are rotated to provide side resistance plates 41. The top surface of the stamping operation plate 1 is provided with a top slide groove 105 that slides with the side resistance plates 41. Through the arrangement of the side resistance plates 41 and the side adjustment screws 4, when the formed steel 100 is transported to the top surface of the stamping seat 2, there is a material resistance plate 1022 on its end face to block it, and its side surface can be adjusted by the side adjustment screws 4 to the position of the side resistance plate 41 at the top surface of the stamping operation plate 1, so that the limit block provided at the bottom of the side resistance plate 41 can slide inside the top slide groove 105, so that the side resistance plate 41 can limit the left and right sides of the formed steel 100, and there is no need to manually hook the formed steel 100 with a claw for position adjustment.

[0028] Example 2 Reference Figure 1-11The difference between this embodiment and embodiment 1 is that a gear box B9 is provided at the bottom end of the stamping operation plate 1, and the output and input ends of the gear box B9 are both connected to the roller shaft 311. A gear box A8 is provided on the side of the bottom surface of the stamping operation plate 1. The setting of the gear box B9 can synchronize the rotation of the roller shafts 311 distributed on the left and right sides of the stamping seat 2. The rotation of the input end of the gear box A8 will be transmitted to the roller shaft 311 through the gear set inside it, and then the gear set inside the gear box B9 will be driven by the roller shaft 311 to rotate, so that the input and output ends of the gear box B9 can rotate in opposite directions at the same speed, so as to realize the same speed and opposite rotation of the two roller shafts 311.

[0029] Specifically, refer to Figure 2 、 Figure 4 and Figure 11 The output end of the gear box A8 is fixedly connected to the roller shaft 311, the bottom end of the output shaft of the gear box A8 is fixedly connected to the input end of the gear box B9, the input end of the gear box A8 is provided with a transmission shaft 81, and the bottom end of the transmission shaft 81 is provided with a driven bevel gear 811.

[0030] Specifically, refer to Figure 5 、 Figure 6 、 Figure 9 and Figure 10 A hanger 5 is provided on the bottom surface of the stamping operation panel 1, and a guide notch 51 is provided on the hanger 5 to provide a limiting guide for the spur rack 7. An auxiliary power supply mechanism 6 is rotatably provided on the hanger 5. The auxiliary power supply mechanism 6 includes a spring box 601 and a spur gear 608 rotatably arranged on the left and right sides of the hanger 5. A pawl plate 607 is provided on the spur gear 608. The teeth of the spur gear 608 are engaged with the teeth of the spur rack 7. A ratchet plate 606 is rotatably provided in the middle of the bottom end of the hanger 5, which is matched with the pawl plate 607 for unidirectional rotation.

[0031] Specifically, refer to Figure 5 、 Figure 6 、 Figure 9 and Figure 10 The ratchet disc 606 is provided with a spring disc 604 that rotates in conjunction with the spring box 601 , and the spring disc 604 is provided with a power storage spring 605 that is fixedly connected to the inner side of the spring box 601 .

[0032] Specifically, refer to Figure 5 、 Figure 6 、 Figure 9 and Figure 10, the mainspring box 601 is provided with a driving shaft 603 which passes through the mainspring disc 604, the ratchet disc 606, the pawl disc 607 and the spur gear 608 in sequence, and the end of the driving shaft 603 is provided with a driving bevel gear 6031 which meshes with the driven bevel gear 811. The position of the lifting seat 104 moves downward, which will cause the spur rack 7 to mesh with the spur gear 608, so that the spur gear 608 rotates forward, thereby allowing the spur gear 608 to drive the pawl disc 607 to rotate. At the same time, the unidirectional rotation matching of the pawl disc 607 and the ratchet disc 606 can allow the pawl disc 607 to drive the ratchet disc 606 to rotate. However, at this time, the lock shaft 602 The lock shaft 602 is located inside the locking groove 1042 on the lifting seat 104, so that the rotation of the lock shaft 602 will be restricted, making it impossible for the spring box 601 to rotate, thereby allowing the power storage spring 605 to be wound and store power. When the lifting seat 104 moves up, the spur rack 7 drives the spur gear 608 to rotate in the opposite direction. At this time, the pawl plate 607 can no longer drive the ratchet plate 606 to rotate synchronously due to the change in rotation direction, and there is a large steering damping between the ratchet plate 606 and the connecting seat provided in the middle of the hanger 5, so that the force accumulated in the power storage spring 605 at this time is not enough to allow the spring plate 604 to rotate.

[0033] Specifically, refer to Figure 10 A lock shaft 602 is provided on the outer surface of the barrel 601, and magnets B6021 with opposite magnetic poles are provided on the left and right sides of the lock shaft 602. When the lock shaft 602 reaches the inside of the rotating groove 1043, the rotation restriction of the lock shaft 602 is released, so that the force accumulated by the power spring 605 can drive the barrel 601 to rotate, thereby allowing the active shaft 603 to drive the active bevel gear 6031 to engage with the driven bevel gear 811, so that the two rollers 311 can rotate indirectly, allowing the pushing plate 332 to push the formed steel 100 into the top surface of the unloading roller group 1021, and the unloading roller group 1021 transports the formed steel 100 to the next production process.

[0034] Specifically, refer to Figure 7-10The lifting seat 104 is provided with a locking frame 1041 on the side, and a locking groove 1042 is provided on the side of the locking frame 1041 to limit the rotation of the lock shaft 602. The bottom of the locking groove 1042 is provided with a rotating groove 1043 for the rotation of the lock shaft 602. The bottom of the lifting seat 104 is provided with arc-shaped plates 1044 on the left and right ends of the rotating groove 1043. The inner surface of the arc-shaped plate 1044 is provided with a magnet A1045 that is attracted and matched with the magnetic pole of the magnet B6021. After the accumulated force is released, the rotation of the lock shaft 602 stops immediately, but the lock shaft 602 will be affected by the magnetic attraction between the magnet B6021 and the magnet A1045 to fine-tune the stop position. After the rotation of the lock shaft 602 stops completely, the magnet A1045 and the magnet B6021 on the same side are in a magnetic attraction state, and the magnetic poles between the two are opposite. At the same time, the magnetic poles of the two magnets B6021 and the two magnets A1045 are opposite when they are set.

[0035] For other structures not described, refer to Example 1.

[0036] Example 3 Reference Figure 1-11 A method for using a U-shaped steel processing device for high-speed rail includes the following steps: S1: The steel plate after the heating treatment is conveyed by the feeding roller group 103 so that the steel plate can reach the top surface of the stamping seat 2; S2: When the steel plate reaches the top surface of the stamping seat 2, the end of the steel plate will be aligned with the top of the material blocking plate 1022. The left and right position of the steel plate can be adjusted by rotating the side adjustment screw 4, so that the side blocking plate 41 can adjust its left and right position, so that the stamping position of the steel plate will not be offset during the downward stamping process of the stamping die. S3: As the lifting seat 104 moves downward, the spur rack 7 drives the spur gear 608 to rotate. The pawl plate 607 and the ratchet plate 606 rotate in one direction, so that the pawl plate 607 can drive the ratchet plate 606 to rotate, thereby causing the mainspring plate 604 to rotate synchronously. At this time, the lock shaft 602 is in the locked position of the lifting seat 104, restricting the rotation of the mainspring box 601, so that the mainspring plate 604 drives the stored mainspring 605 to tighten; S4: After the stamping process is completed, the formed steel material 100 is obtained, and then the jacking seat 104 drives the stamping seat 2 to push the formed steel material 100 upward until the top surfaces of the two ends of the stamping seat 2 are flush with the top surface of the stamping operation plate 1. At this time, the meshing and matching effect between the spur rack 7 and the spur gear 608 will prevent the pawl plate 607 from driving the ratchet plate 606 to rotate; S5: When the top surfaces at both ends of the punching seat 2 are flush with the top surface of the punching operation plate 1, the lock shaft 602 will cooperate with the lifting seat 104 to release its rotation lock on the clockwork box 601, so that the active bevel gear 6031 at the end of the active shaft 603 will engage and match with the driven bevel gear 811, thereby allowing the gear sets inside the gear box A8 and the gear box B9 to rotate, and synchronously drive the two active rollers 31 to rotate in opposite directions at the same speed, so that the transmission chain 33 is adjusted in position, so that the pushing plate 332 acts on the end face of the formed steel 100 to push the formed steel 100 to the top surface of the unloading roller group 1021, and the unloading roller group 1021 transports the formed steel 100 to the next production process.

[0037] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by a person skilled in the art. The provision of power is also common knowledge in the art. The present invention is mainly used to protect mechanical devices, so the control method and circuit connection are not explained in detail in the present invention.

[0038] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.

A ratchet disc (607) is provided on the spur gear (608), and the teeth of the spur gear (608) mesh with the teeth of the spur rack (7). A ratchet disc (606) is rotatably provided at the middle of the bottom end of the hanger (5) and is matched with the ratchet disc (607) for unidirectional rotation.

7. The U-shaped steel processing equipment for high-speed railway according to claim 6, characterized in that: The ratchet disc (606) is provided with a spring disc (604) that rotates in conjunction with the spring box (601), and the spring disc (604) is provided with a power storage spring (605) that is fixedly connected to the inner side of the spring box (601).

8. The U-shaped steel processing equipment for high-speed railway according to claim 7, characterized in that: The mainspring box (601) is provided with a driving shaft (603) that sequentially passes through the mainspring disc (604), the ratchet disc (606), the pawl disc (607), and the spur gear (608). The end of the driving shaft (603) is provided with a driving bevel gear (6031) that meshes with the driven bevel gear (811).

9. The U-shaped steel processing equipment for high-speed railway according to claim 8, characterized in that: The outer surface of the clockwork box (601) is provided with a lock shaft (602), and magnets B (6021) with opposite magnetic poles are provided on both the left and right sides of the lock shaft (602).

10. A method for using the high-speed railway U-shaped steel processing equipment according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: The steel plate after the heating treatment is transported through the feeding roller group (103) so that the steel plate can reach the top surface of the punching seat (2); S2: When the steel plate reaches the top surface of the punching seat (2), the end of the steel plate will be aligned with the top of the material blocking plate (1022), and the left and right positions of the steel plate can be adjusted by the rotation of the side adjustment screw (4), so that the side blocking plate (41) can adjust its left and right positions, so that the stamping position of the steel plate will not be offset during the downward stamping process of the stamping die; S3: When the lifting seat (104) moves downward, the spur gear (7) drives the spur gear (608) to rotate. The pawl disc (607) and the ratchet disc (606) rotate in one direction, so that the pawl disc (607) can drive the ratchet disc (606) to rotate, thereby allowing the spring disc (604) to rotate synchronously. At this time, the lock shaft (602) is in the locking position of the lifting seat (104), which limits the rotation of the spring box (601), thereby allowing the spring disc (604) to drive the power storage spring (605) to be tightened; S4: After the stamping process is completed, the formed steel material (100) is obtained, and then the jacking seat (104) drives the stamping seat (2) to push the formed steel material (100) upward until the top surfaces of the two ends of the stamping seat (2) are flush with the top surface of the stamping operation plate (1). At this time, the meshing matching effect between the spur rack (7) and the spur gear (608) will not allow the pawl plate (607) to drive the ratchet plate (606) to rotate; S5: When the top surfaces of both ends of the punching seat (2) are flush with the top surface of the punching operation plate (1), the lock shaft (602) cooperates with the lifting seat (104) to release the rotation lock of the barrel (601), so that the active bevel gear (6031) at the end of the active shaft (603) will mesh with the driven bevel gear (811), thereby rotating the gear sets inside the gear box A (8) and the gear box B (9), and synchronously driving the two active rollers (31) to rotate in opposite directions at the same speed, so that the transmission chain (33) is adjusted in position, so that the push plate (332) acts on the end surface of the formed steel (100) to push the formed steel (100) to the top surface of the unloading roller group (1021), and the unloading roller group (1021) transports the formed steel (100) to the next production process.
