Description

Technical Field

[0001] The present invention relates to the technical field of plate shears, and particularly to a hydraulic swing-type plate shear with a lighting alignment mechanism and a method thereof. Background Art

[0002] A swing-type plate shear is a plate shear driven hydraulically. It relies on the rotation of the tool holder to achieve the shearing process. Compared with ordinary plate shears, the swing-type plate shear mostly uses inclined-edge shearing. Due to its simple structure, low failure rate, high shearing efficiency, and no bowing, warping, or twisting deformation of the plate after shearing, it is widely used. During the shearing process, as the tool holder makes a rotary motion, the shearing back angle and shearing gap of the swing-type plate shear will change; Patent No. 201520748809.2 discloses a hydraulic swing-type plate shear, which adopts an integral welded frame structure, has good machine tool rigidity and high shearing accuracy.

[0003] In the above patent, during the actual working process of the swing shaft of the plate shear, when the pressure tool contacts the plate part, a strong reaction force will be generated. This force will be directly transmitted through the pressure tool to the entire swing shaft, thereby causing wear on the drive of the swing shaft and the movable joints; therefore, it does not meet the existing requirements, and for this reason, a hydraulic swing-type plate shear with a lighting alignment mechanism and a method thereof are proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a hydraulic swing-type plate shear with a lighting alignment mechanism and a method thereof. When the motor drives the half-axis gear, after the area with tooth grooves on the gear surface meshes with the full-axis gear, it will drive the full-axis gear and the hydraulic swing shaft to rotate. And when the hydraulic swing shaft is shearing the plate part instantaneously, the meshing relationship between the full-axis gear and the half-axis gear will be released, and the high-speed rotation is used in combination with the inertia of the hydraulic swing shaft to complete the shearing operation. At the same time, the reaction force generated during the shearing of the pressure tool on the hydraulic swing shaft will not be transmitted to the half-axis gear through the full-axis gear, thereby reducing the wear between the two, and the problems in the prior art can be solved.

Correction frames are provided at both ends of the bottom of the adapter sleeve frame. The limit truss at one end of the correction frame is bolted to the main frame of the shearing machine.

[0009] Preferably, a lead screw slider is provided on the outer surface of the linkage lead screw. A magnet knife holder is provided at one end of the lead screw slider. The magnet knife holder is slidably connected to the linkage lead screw through the lead screw slider. The magnet knife holder is bolted to the upper pressing knife. A tool mounting shaft is provided at one end of the hydraulic swing shaft. The tool mounting shaft is attached to the upper pressing knife in a fitting manner.

[0010] Preferably, an infrared ranging module is provided inside the tool mounting shaft. A lower pressing knife is provided outside the upper pressing knife. The lower pressing knife is bolted to the workpiece horizontal support through a spacing bolt. An air-operated pressing plate assembly is provided above the lower pressing knife. The air-operated pressing plate assembly is screwed to the working guard plate.

[0011] Preferably, a counter shaft is provided at one end of the air-operated pressing plate assembly. The counter shaft extends into the air-operated pressing plate assembly. An air piston is provided at the other end of the counter shaft.

[0012] Preferably, a buffer spring is provided between the air piston and the air-operated pressing plate assembly. A cylinder interface is provided at the other end of the air-operated pressing plate assembly. The cylinder interface is connected to the pneumatic unit through a pipeline.

[0013] The present invention provides another technical solution: A method for using a hydraulic swing-type shearing machine with a lighting alignment mechanism, including the following steps:

[0014] Step 1: Place the plate member above the suspension rod platform. Push the plate member to enter the area of the lower pressing knife from below the metal fence until the plate member is in contact with the upper pressing knife. At this time, the magnetism of the magnet knife holder will adsorb the plate member on the surface of the upper pressing knife, and the laser alignment module senses the information of the plate member;

[0015] Step 2: After determining the shearing length of the plate, the screw rod slider drives the magnet cutter holder and the upper pressing cutter to move inward, and the plate moves together. After moving to the specified length, the pneumatic pressing plate assembly controls the pressing shaft to press down and tighten on the surface of the plate.

[0016] Step 3: The motor outside the unit drives the half-axis gear to drive the full-axis gear and the hydraulic swing shaft to turn up. Subsequently, the screw rod slider controls the magnet cutter holder to reset to the tool loading shaft area. After the reset, the hydraulic swing shaft turns down.

[0017] Step 4: During the pressing-down process, the upper pressing cutter presses tightly between the plate and the lower pressing cutter, thus completing the shearing process. The parts generated by shearing slide out from the blanking plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. In the present invention, two groups of gear structures are installed inside the correction transmission sleeve box, namely the full-axis gear and the half-axis gear. Among them, only 1 / 3 of the surface of the half-axis gear is provided with tooth grooves, and the two are rotationally connected through meshing of the tooth grooves. The half-axis gear is rotationally connected with the motor, and the full-axis gear is connected with the hydraulic swing shaft. When the motor drives the half-axis gear, after the area with tooth grooves on the gear surface meshes with the full-axis gear, it will drive the full-axis gear and the hydraulic swing shaft to rotate. When the hydraulic swing shaft shears the plate instantaneously, the meshing relationship between the full-axis gear and the half-axis gear will be released, and the high-speed rotation is used in combination with the inertia of the hydraulic swing shaft to complete the shearing operation. At the same time, the reaction force generated when the pressing cutter on the hydraulic swing shaft shears will not be transmitted to the half-axis gear through the full-axis gear, thereby reducing the wear between the two. After the acting force disappears, the motor rotates reversely to make the half-axis gear and the full-axis gear mesh again.

[0020] 2. In the present invention, before the shearing operation, the plate is first attached to the upper pressing cutter, and the plate is adsorbed on the surface of the upper pressing cutter by the magnetism of the magnet cutter holder. At the same time, the laser alignment module located above can sense the position information of the plate immediately, and then determine the shearing length of the plate. After that, the screw rod slider inside the adapter sleeve frame is controlled to drive the magnet cutter holder and the upper pressing cutter to move inward along the linkage screw rod. Due to the influence of magnetic adsorption, the plate will move together with the magnet cutter holder. After moving to the specified length, the pneumatic pressing plate assembly presses down to tighten the surface of the plate. The motor outside the unit drives the half-axis gear to drive the full-axis gear and the hydraulic swing shaft to turn up. During the lifting process, the screw rod slider will control the magnet cutter holder to reset to the tool loading shaft area. After the reset, the hydraulic swing shaft drives the upper pressing cutter to turn down, and the upper pressing cutter is used in combination with the lower pressing cutter to complete the shearing operation on the plate.

[0021] 3. In the present invention, after air pressure is injected into the upper part of the pneumatic piston through the cylinder interface, the pneumatic piston can be pushed to move downward, thereby pressing the abutting shaft against the surface of the plate. When the cutting knife shears the plate, the shearing force will act on half of the plate. At this time, an upward force will occur on the plate pressed by the abutting shaft. The buffer spring between the abutting shaft and the pneumatic piston can help the pressing plate assembly buffer this reverse force and prevent the plate from warping and deforming.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1-2 , an embodiment provided by the present invention: a hydraulic swing shearing machine with a lighting line alignment mechanism, including a main frame 1 of the shearing machine. There is a pneumatic unit 2 arranged on the top of the main frame 1 of the shearing machine. There is a wire routing bracket 202 arranged between the pneumatic unit 2 and the main frame 1 of the shearing machine. A laser line alignment module 203 is arranged below the wire routing bracket 202. A driving motor 201 is arranged on the top of the pneumatic unit 2. A working guard plate 3 is arranged on the outer side of the top of the main frame 1 of the shearing machine. An operation module 103 is arranged on the outer surface of the working guard plate 3. A metal fence 4 is arranged at the bottom of the working guard plate 3. A workpiece horizontal support 5 below the metal fence 4 is bolted to the main frame 1 of the shearing machine. A suspension rod platform 501 is arranged on the outer side of the workpiece horizontal support 5. A power control chassis 101 is arranged above one end of the main frame 1 of the shearing machine. Correction transmission sleeve boxes 102 are arranged at both ends of the main frame 1 of the shearing machine. A full-axis gear 1021 is arranged inside the correction transmission sleeve box 102. A half-axis gear 1022 is arranged below the full-axis gear 1021. The half-axis gear 1022 is rotationally connected to the motor. The full-axis gear 1021 and the half-axis gear 1022 are meshed and rotationally connected;

[0031] Two groups of gear structures are installed inside the correction transmission sleeve box 102, namely a full-axis gear 1021 and a half-axis gear 1022. Among them, only 1 / 3 of the surface of the half-axis gear 1022 is provided with tooth grooves. The two are meshed and rotationally connected through the tooth grooves. The half-axis gear 1022 is rotationally connected to the motor, and the full-axis gear 1021 is connected to the hydraulic swing shaft 6. When the motor drives the half-axis gear 1022, after the area with tooth grooves on the gear surface meshes with the full-axis gear 1021, it will drive the full-axis gear 1021 and the hydraulic swing shaft 6 to rotate. And when the hydraulic swing shaft 6 shears the plate at the moment, the meshing relationship between the full-axis gear 1021 and the half-axis gear 1022 will be released. The shearing operation is completed by using the high-speed rotation and the inertia of the hydraulic swing shaft 6. At the same time, the reaction force generated when the pressing knife on the hydraulic swing shaft 6 shears will not be transmitted to the half-axis gear 1022 through the full-axis gear 1021, thereby reducing the wear between the two. After the acting force disappears, the motor reverses to make the half-axis gear 1022 and the full-axis gear 1021 mesh again.

[0032] Please refer to Figure 3-5, a hydraulic swing shaft 6 is arranged below the pneumatic unit 2. Swing coupling shafts 602 are arranged at both ends of the hydraulic swing shaft 6. The swing coupling shafts 602 are rotationally connected to the main frame 1 of the shearing machine through full-axis gears 1021. A transfer sleeve frame 601 between the swing coupling shafts 602 is bolted to the hydraulic swing shaft 6. A linkage lead screw 6011 is arranged inside the transfer sleeve frame 601. The linkage lead screw 6011 is rotationally connected to the transfer sleeve frame 601 through a transmission end shaft 6012. Correction frames 6014 are arranged at both ends of the bottom of the transfer sleeve frame 601. A limit truss 6015 at one end of the correction frame 6014 is bolted to the main frame 1 of the shearing machine. A lead screw slider 6013 is arranged on the outer surface of the linkage lead screw 6011. A magnet knife holder 6016 is arranged at one end of the lead screw slider 6013. The magnet knife holder 6016 is slidably connected to the linkage lead screw 6011 through the lead screw slider 6013. The magnet knife holder 6016 is bolted to the upper pressing knife 604. A tool mounting shaft 603 is arranged at one end of the hydraulic swing shaft 6. The tool mounting shaft 603 is in fit connection with the upper pressing knife 604. An infrared ranging module 6031 is arranged inside the tool mounting shaft 603. A lower pressing knife 503 is arranged outside the upper pressing knife 604. The lower pressing knife 503 is connected to the workpiece horizontal support 5 through a spacing bolt 502. A pneumatic pressing plate assembly 7 is arranged above the lower pressing knife 503. The pneumatic pressing plate assembly 7 is screwed to the working guard plate 3;

[0033] Before the shearing operation, first fit the plate with the upper pressing knife 604, and use the magnetism of the magnet knife holder 6016 to adsorb the plate on the surface of the upper pressing knife 604. At the same time, the laser alignment module 203 located above can sense the position information of the plate in the first time, and then determine the shearing length of the plate. Then, control the lead screw slider 6013 inside the transfer sleeve frame 601 to drive the magnet knife holder 6016 and the upper pressing knife 604 to move inward along the linkage lead screw 6011. Due to the influence of magnetic adsorption, the plate will move together with the magnet knife holder 6016. After moving to the specified length, press down the plate surface through the pneumatic pressing plate assembly 7. The motor outside the unit drives the half-axis gear 1022 to drive the full-axis gear 1021 and the hydraulic swing shaft 6 to turn up. During this process, the plate is pressed by the pneumatic pressing plate assembly 7, so it will not be affected by magnetic adsorption and shift. During the lifting process, the lead screw slider 6013 will control the magnet knife holder 6016 to reset to the area of the tool mounting shaft 603. The infrared ranging module 6031 can help the tool mounting shaft 603 to determine the distance between the magnet knife holder 6016 and the tool mounting shaft 603. After the reset is completed, the hydraulic swing shaft 6 drives the upper pressing knife 604 to turn down and press, and use the upper pressing knife 604 to cooperate with the lower pressing knife 503 to complete the shearing operation of the plate;

[0034] The lower pressing knife 503 is connected to the workpiece horizontal support 5 through a spacing bolt 502. By rotating the spacing bolt 502, the distance between the lower pressing knife 503 and the workpiece horizontal support 5 can be controlled;

[0035] Correction frames 6014 are provided at both ends of the bottom of the adapter sleeve 601. A limit truss 6015 is installed below one end of the correction frame 6014. During the rotation of the hydraulic swing shaft 6, the limit truss 6015 can cooperate with the correction frame 6014 to limit the downward rotation angle of the hydraulic swing shaft 6.

[0036] Please refer to Figure 6 , one end of the pneumatic pressing plate assembly 7 is provided with a shaft abutment 701. The shaft abutment 701 extends into the pneumatic pressing plate assembly 7. The other end of the shaft abutment 701 is provided with a pneumatic piston 702. A buffer spring 704 is provided between the pneumatic piston 702 and the pneumatic pressing plate assembly 7. The other end of the pneumatic pressing plate assembly 7 is provided with a cylinder interface 703. The cylinder interface 703 is connected to the pneumatic unit 2 through a pipeline;

[0037] After the air pressure is injected above the pneumatic piston 702 through the cylinder interface 703, the pneumatic piston 702 can be pushed to move downward, so as to press the shaft abutment 701 against the surface of the plate. When the cutting knife shears the plate, the shearing force will be generated on half of the plate. At this time, an upward force will appear on the plate suppressed by the shaft abutment 701. The buffer spring 704 between the shaft abutment 701 and the pneumatic piston 702 can help the pressing plate assembly buffer this reverse force and prevent the plate from warping and deforming.

[0038] In order to better show the usage process of the hydraulic swing-type shearing machine with a lighting alignment mechanism, this embodiment proposes a usage method of the hydraulic swing-type shearing machine with a lighting alignment mechanism, including the following steps:

[0039] Step 1: Place the plate above the suspension rod platform 501, and push the plate to enter the area of the lower cutting knife 503 from below the metal fence 4 until the plate fits with the upper cutting knife 604. At this time, the magnetism of the magnet knife holder 6016 will adsorb the plate on the surface of the upper cutting knife 604, and the laser alignment module 203 senses the information of the plate;

[0040] Step 2: After determining the shearing length of the plate, the screw rod slider 6013 drives the magnet knife holder 6016 and the upper cutting knife 604 to move inward, and the plate moves together. After moving to the specified length, the pneumatic pressing plate assembly 7 controls the shaft abutment 701 to press down and clamp on the surface of the plate;

[0041] Step 3: The motor outside the unit drives the half-shaft gear 1022 to drive the full-shaft gear 1021 and the hydraulic swing shaft 6 to turn up. Subsequently, the screw rod slider 6013 controls the magnet knife holder 6016 to reset to the tool loading shaft 603 area. After the reset, the hydraulic swing shaft 6 turns down;

[0042] Step 4: During the downward pressing process, the upper pressing knife 604 presses the plate tightly against the lower pressing knife 503, thus completing the shearing process. The parts generated by shearing slide out from the blanking plate 104.

[0043] Working principle: First, the plate is attached to the upper pressing knife 604, and the plate is adsorbed on the surface of the upper pressing knife 604 by the magnetism of the magnet knife holder 6016. At the same time, the laser alignment module 203 located above can sense the position information of the plate immediately. Subsequently, the shearing length of the plate is determined. Then, the lead screw slider 6013 inside the adapter sleeve holder 601 drives the magnet knife holder 6016 and the upper pressing knife 604 to move inward along the linkage lead screw 6011. Due to the influence of magnetic adsorption, the plate will move together with the magnet knife holder 6016. After moving to the specified length, it is injected above the pneumatic piston 702 through the cylinder interface 703, and then the pneumatic piston 702 can be pushed to move downward, thereby pressing the abutting shaft 701 against the surface of the plate. When the pressing knife shears the plate, the shearing force will act on half of the plate. At this time, the plate pressed by the abutting shaft 701 will generate an upward force. The buffer spring 704 between the abutting shaft 701 and the pneumatic piston 702 can help the pressing plate assembly buffer this reverse force and prevent the plate from warping and deforming. The motor outside the unit drives the half shaft gear 1022 to drive the full shaft gear 1021 and the hydraulic swing shaft 6 to turn up. During this process, the plate is pressed by the pneumatic pressing plate assembly 7, so it is not affected by magnetic adsorption and does not shift. During the lifting process, the lead screw slider 6013 will control the magnet knife holder 6016 to reset to the tool loading shaft 603 area, and the infrared ranging module 6031 can help the tool loading shaft 603 determine the distance between the magnet knife holder 6016 and the tool loading shaft 603. After the reset is completed, the hydraulic swing shaft 6 drives the upper pressing knife 604 to turn downward and complete the shearing operation of the plate by using the upper pressing knife 604 in cooperation with the lower pressing knife 503.
