Description

Technical Field

[0001] The invention relates to the technical field of plate processing equipment, in particular to a fast plate shearing machine. Background Art

[0002] Shearing machine is a machine that uses one blade to make a reciprocating linear motion relative to another blade to shear the plate. It uses the moving upper blade and the fixed lower blade, and adopts a reasonable blade gap to apply shear force to metal plates of various thicknesses, so that the plates are broken and separated according to the required size.

[0003] At present, the shearing drive and feeding drive of the shearing machine are generally driven by two sets of driving mechanism groups. When shearing, the feeding drive mechanism group stops working, and when feeding, the shearing mechanism group stops working. The feeding and shearing of the plate are realized by cross-starting the shearing mechanism group and the feeding mechanism group. Therefore, the shearing mechanism group and the feeding mechanism group need to be started alternately during the shearing and feeding process, and there is a certain switching delay, which affects the production efficiency and accuracy; and the shearing mechanism group and the feeding mechanism group are started alternately, and the synchronization between the two is required to be high. Once the synchronization is inaccurate, the position of the plate will be misaligned during the shearing and feeding process, affecting the cutting quality; in addition, the cross-starting of the shearing mechanism group and the feeding mechanism group will increase the complexity of the system, increase the probability of system failure, and reduce the stability and reliability of the system. The shearing mechanism group and the feeding mechanism group need to be started alternately, which is more complicated to maintain, the maintenance workload increases, and the maintenance cost will also increase accordingly. In order to improve the shearing efficiency while reducing the failure rate of the shearing mechanism group, a fast shearing machine is proposed. Summary of the invention

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] Example: Refer to Figure 1-Figure 11A fast shearing machine comprises a shearing machine chassis 1, and also comprises: a transmission mechanism group, which is arranged on the outside of the shearing machine chassis 1, one end of which extends into the shearing machine chassis 1; a movable shearing mechanism group and a fixed shearing plate 36, wherein the movable shearing mechanism group is arranged on the shearing machine chassis 1, and the fixed shearing plate 36 is fixedly installed on one end of the transmission mechanism group extending into the shearing machine chassis 1; a driving mechanism group, which is arranged on the shearing machine chassis 1 and is used to drive the movable end of the movable shearing mechanism group to reciprocate and lift to shear the plate; a transmission mechanism group and a gearbox 17, both of which are arranged in the shearing machine chassis 1, wherein the output end of the transmission mechanism group is transmission-connected with the input end of the gearbox 17, the input end of the transmission mechanism group is transmission-connected with the movable end of the movable shearing mechanism group, and the output end of the gearbox 17 is transmission-connected with the driving end of the transmission mechanism group through a ratchet assembly 19; when the shearing end of the movable shearing mechanism group rises higher than the plate, the input end of the transmission mechanism group drives the output end to rotate.

[0021] When in use, when the movable end of the movable shearing mechanism group is reciprocatingly lifted and lowered, the lowest part of the shearing end of the movable shearing mechanism group moves from top to bottom to shear the plate. During the shearing process, under the action of the ratchet assembly 19, the conveying mechanism group does not feed the plate. During the rising process of the shearing end, when the bottom of the shearing end is lower than the top of the plate, the conveying mechanism group does not work. When the bottom of the shearing end is higher than the plate, the driving mechanism group, the shearing mechanism group and the transmission mechanism group cooperate to drive the conveying mechanism group to convey the plate. The conveying mechanism group, the movable mechanism group, the driving mechanism group and the transmission mechanism group are connected by a mechanical structure for transmission, so that the lifting speed of the shearing end of the shearing mechanism group is proportional to the transmission distance of the conveying mechanism group.

[0022] Compared with the shearing of plates by the cooperation of two sets of driving mechanisms, the rapid shearing machine integrates the shearing drive and the feeding drive, and realizes the seamless connection of the shearing and conveying processes through the coordinated work of the movable shearing mechanism group, the transmission mechanism group and the conveying mechanism group, avoiding the switching delay of the alternating start-up of the shearing mechanism group and the feeding mechanism group; and because the shearing and conveying processes do not require the alternating start-up of the shearing mechanism group and the feeding mechanism group, the switching delay is reduced, the production efficiency and accuracy are improved, and the positional misalignment of the plates during the shearing and feeding processes is avoided; in addition, the integrated design reduces the synchronization requirements between the shearing mechanism group and the feeding mechanism group, reduces the system complexity, reduces the probability of system failure, and improves the stability and reliability of the system; and there is no need to alternately start the shearing mechanism group and the feeding mechanism group, which simplifies the maintenance process, reduces the maintenance workload and maintenance costs, and improves the reliability and stability of the equipment.

[0023] In summary, compared with the existing shearing machines, the rapid shearing machine has the advantages of integrated design, improved production efficiency and precision, simplified system structure and reduced maintenance costs.

[0024] Reference Figure 2 and Figure 7 The conveying mechanism group includes a mounting frame 20, a fixed shear plate 36 is fixedly connected to the mounting frame 20, a gearbox 17 is fixedly connected to the side wall of the mounting frame 20, a rotating shaft 21 is rotatably connected to the mounting frame 20, a transmission roller 22 is fixedly connected to the rotating shaft 21, a transmission belt 23 is coupled to the transmission roller 22, a positioning block 24 is fixedly connected to the transmission belt 23, and a left and right positioning mechanism group is arranged at the bottom of the conveying mechanism group.

[0025] During the driving process, the driving mechanism group drives the shearing end of the movable shearing mechanism group to reciprocate and rise and fall. During the reciprocating and rising process of the shearing end of the movable shearing mechanism group, the input shaft of the gearbox 17 is driven to rotate through the transmission mechanism group, and the output shaft of the gearbox 17 drives the driving wheel of the ratchet assembly 19 to rotate, and the driving wheel of the ratchet assembly 19 drives the driven wheel of the ratchet assembly 19, and the driven wheel of the ratchet assembly 19 drives the rotating shaft 21 to rotate intermittently, wherein the number of rotations of the rotating shaft 21 is controlled by the gearbox 17, the rotating shaft 21 drives the transmission roller 22 to rotate, and the transmission roller 22 drives the transmission belt 23 to rotate, thereby transmitting the plate.

[0026] Among them, the gearbox 17 can adopt a multi-stage transmission or a continuously variable transmission, wherein the transmission ratio between the input shaft and the output shaft of the gearbox 17 changed in each stage of the multi-stage transmission is constant, which is suitable for the processing of plates with little change in shearing distance, and the transmission ratio between the output shaft and the input shaft of the continuously variable transmission can be changed arbitrarily, which is suitable for the processing of workpieces with non-fixed plate sizes.

[0027] Reference Figure 2 The driving mechanism group includes a motor 11, a second mounting plate 10 is fixedly connected to the outer wall of the shearing machine chassis 1, the motor 11 is fixedly connected to the second mounting plate 10, a mounting shaft 6 is rotatably connected in the shearing machine chassis 1, the mounting shaft 6 is fixedly connected to the output shaft of the motor 11, a crankshaft 7 is fixedly connected to the mounting shaft 6, a crank arm 8 is rotatably connected to the crankshaft 7, a connecting seat 9 is rotatably connected to the crank arm 8, and the connecting seat 9 is fixedly connected to the movable end of the movable shearing mechanism group; the movable shearing mechanism group includes a first mounting plate 2 fixedly connected to the inner wall of the shearing machine chassis 1, a guide rail 3 is fixedly connected to the first mounting plate 2, a connecting plate 4 is slidably connected to the guide rail 3, the connecting plate 4 is fixed to the connecting seat 9 by bolts, and a cutter 5 is fixedly installed at the bottom of the connecting plate 4.

[0028] Start the motor 11, the motor 11 drives the mounting shaft 6 to rotate, the mounting shaft 6 drives the crankshaft 7 to rotate, the crankshaft 7 drives the connecting plate 4 to reciprocate and rise and fall through the crank arm 8, the connecting plate 4 drives the cutter 5 to reciprocate and rise and fall on the guide rail 3 to cooperate with the fixed shear plate 36 to shear the plate.

[0029] Reference Figure 2 , Figure 4 ,and Figure 6 The transmission mechanism group includes a rack 12 fixedly connected to the side wall of the connecting plate 4, and a transmission gear 13 is rotatably connected to the outer wall of the guide rail 3, and the transmission gear 13 is meshed with the rack 12; a third mounting plate is fixedly connected to the side wall of the guide rail 3, and a first transmission shaft 15 is rotatably mounted on the third mounting plate, and the first transmission shaft 15 rotates synchronously with the input shaft of the gearbox 17 through the second bevel gear set 18 (the second bevel gear set 18 is composed of two meshing bevel gears, and the two bevel gears are respectively fixedly connected to the first transmission shaft 15 and the input shaft of the gearbox 17); the first transmission shaft 1 5 is fixedly connected with a sealing cylinder 151 on the top, and the second transmission shaft 16 is rotatably connected to the sealing cylinder 151. The second transmission shaft 16 rotates synchronously with the transmission gear 13 through the first bevel gear set 14 (the first bevel gear set 14 is composed of two meshing bevel gears, and the two bevel gears are fixedly connected to the second transmission shaft 16 and the transmission gear 13 respectively); a limiting block 152 is fixedly connected in the sealing cylinder 151, and the second transmission shaft 16 extends into the sealing cylinder 151 and is fixedly connected with a driving block 161, and a buffer medium is provided between the driving block 161 and the limiting block 152.

[0030] During use, the connecting plate 4 drives the rack 12 to reciprocate and rise and fall, and the rack 12 drives the transmission gear 13 to rotate when it reciprocates and rises and falls. The transmission gear 13 drives the second transmission shaft 16 to rotate through the first bevel gear set 14. Before the driving block 161 contacts the limit block 152, the second transmission shaft 16 drives the first transmission shaft 15 to rotate. During this time period, the cutter 5 rises to the top of the plate, and then the cutter 5 continues to rise. The driving block 161 drives the first transmission shaft 15 to rotate through the limit block 152. The first transmission shaft 15 drives the input shaft of the gearbox 17 to rotate through the second bevel gear set 18. The output shaft of the gearbox 17 drives the rotating shaft 21 to rotate through the ratchet assembly 19, thereby driving the transmission belt 23 to rotate to feed the plate. When the cutter 5 descends to shear the plate, the rotating shaft 21 does not rotate under the action of the ratchet assembly 19.

[0031] Among them, the buffer medium can be hydraulic oil or refrigerant: Reference Fig.10 When hydraulic oil is selected as the buffer medium, the limit block 152 and the driving block 161 divide the sealing cylinder 151 into a first chamber 153 and a second chamber 154. A gap connecting the first chamber 153 and the second chamber 154 is provided between the side wall of the driving block 161 and the inner wall of the sealing cylinder 151. Therefore, when the second transmission shaft 16 drives the block 161 to rotate, the hydraulic oil flows back and forth in the first chamber 153 and the second chamber 154 through the gap. The flow of hydraulic oil through the gap reduces the contact force between the two driving blocks 161 and the limit blocks 152, thereby preventing damage to both the driving blocks 161 and the limit blocks 152 when they come into contact and collide.

[0032] Reference Figure 2-Figure 6 and Fig. 9 When the refrigerant is used as the buffer medium, the stop block 152 and the driving block 161 divide the sealing cylinder 151 into a first chamber 153 and a second chamber 154. The first chamber 153 and the second chamber 154 are both independently sealed. The first transmission shaft 15 and the stop block 152 are provided with a first through hole 155 communicating with the first chamber 153 and the second chamber 154. The refrigerant in the first chamber 153 and the second chamber 154 is discharged through the first through hole 155; the second transmission shaft 16 and the driving block 161 are provided with a second through hole 162 communicating with the first chamber 153 and the second chamber 154. The refrigerant enters the first chamber 153 and the second chamber 154 alternately through the second through hole 162, and also includes an installation box 29, a heat exchange tube 30 is fixedly connected to the installation box 29, the output end of the heat exchange tube 30 is fixedly connected to the expansion valve 311, the output end of the expansion valve 311 is fixedly connected to the second pipeline 31, a first heat exchange hole 25 is opened between the connecting plate 4 and the cutter 5, the input end of the first heat exchange hole 25 is connected to the output end of the second pipeline 31; the output end of the first heat exchange hole 25 is fixedly connected to the first pipeline 26, and the output end of the first pipeline 26 is fixedly connected to the first rotating joint 2 7, the rotating end of the first rotating joint 27 is fixedly connected to the second transmission shaft 16, the input end of the heat exchange tube 30 is fixedly connected to the overflow valve 301, the input end of the overflow valve 301 is fixedly connected to the connecting pipe, the input end of the connecting pipe is fixedly connected to the second rotating joint 28, the rotating end of the second rotating joint 28 is fixedly connected to the first transmission shaft 15, wherein the overflow valve 301 and the expansion valve 311 are both one-way channel valves; a second heat exchange hole 37 is opened in the fixed shear plate 36, a mounting cylinder 32 is fixedly connected to the outer wall of the shearing machine chassis 1, and a gear speed increaser 33 is fixedly connected in the mounting cylinder 32 The input shaft of the gear speed increaser 33 is fixedly connected to the mounting shaft 6, the output end of the gear speed increaser 33 is fixedly connected to the fan blade 34, the exhaust end of the mounting tube 32 is fixedly connected to the third pipe 35, and the output end of the third pipe 35 is connected to the air inlet end of the mounting box 29; the exhaust end of the mounting box 29 is fixedly connected to the fourth pipe 38, the output end of the fourth pipe 38 is fixedly connected to the three-way control valve 39, the first output end of the three-way control valve 39 is fixedly connected to the exhaust pipe 40, the second output end of the three-way control valve 39 is fixedly connected to the fifth pipe 41, and the fifth pipe 41 is connected to the second heat exchange hole 37.

[0033] In this embodiment, when the second transmission shaft 16 causes the driving block 161 to reciprocate, and because a seal is provided between the driving block 161 and the sealing cylinder 151, when the driving block 161 reciprocates, the driving block 161 acts as a piston to drive the refrigerant to circulate. During the circulation process, the refrigerant passes through the cavity (the first chamber 153 and the second chamber 154), the first through hole 155, the second rotary joint 28, the connecting pipe, the overflow valve 301, the heat exchange tube 30, the expansion valve 311, the second pipeline 31, the first heat exchange hole 25, the first pipeline 26, the first rotary joint 27, the first through hole 155 in sequence, and then enters the cavity again to circulate.

[0034] Among them, the refrigerant absorbs the heat generated by the cutter 5 shearing the plate in the first heat exchange hole 25 and evaporates to become a high-temperature, low-pressure gas, and then increases the pressure through the overflow valve 301 to become a high-temperature, high-pressure gas. The wind blown out by the fan blades 34 exchanges heat and cools down in the heat exchange tube 30, and then expands into a low-temperature, low-pressure liquid through the expansion valve 311 and enters the first heat exchange hole 25.

[0035] To sum up, the refrigerant can not only absorb the heat of the cutter 5 shearing the plate in the first heat exchange hole 25 to prevent the cutter 5 from being damaged due to excessive temperature when shearing the plate at high speed, but also serve as a buffer between the drive block 161 and the limit block 152 to prevent the drive block 161 and the limit block 152 from colliding and deforming. Compared with the traditional refrigeration system, the refrigeration system does not need to install a compressor, thereby reducing the cost of the refrigeration system.

[0036] When the mounting shaft 6 rotates, the gear speed increaser 33 is driven (the gear speed increaser 33 is the same as the reduction box, and the output shaft and the input shaft of the reduction box originally used for deceleration are swapped in direction to increase the output speed) to drive the fan blades 34 to rotate at high speed. The fan blades 34 rotate at high speed to absorb external air and discharge it into the mounting box 29 through the third pipe 35, and blow it toward the heat exchange tube 30, and exchange heat with the high-temperature cooling medium in the heat exchange tube 30, thereby reducing the temperature of the cooling medium in the heat exchange tube 30, and then obtaining a hot air flow.

[0037] During shearing, the hot air flow can be introduced into the second heat exchange hole 37, and the heat can be introduced into the plate through the fixed shear plate 36 to heat the plate, reduce the internal stress of the plate, and improve the shearing effect; when the plate does not need to be preheated, the hot air can be discharged through the exhaust pipe 40.

[0038] Reference Figure 2 and Figure 7The left and right alignment mechanism groups include a guide rod 42 fixedly connected to the bottom of the mounting frame 20, and two groups of alignment plates 43 are slidably connected to the guide rod 42. Two groups of alignment plates 43 are provided, and the two groups of alignment plates 43 are symmetrically arranged on the guide rod 42. A double screw rod 44 is rotatably connected to the mounting frame 20, and the two ends of the double screw rod 44 are respectively threadedly connected to the two alignment plates 43.

[0039] The double-screw screw 44 is rotated to drive the two alignment plates 43 to move toward or away from the conveyor belt 23 at the same time through the guide rod 42, and the convergence of the two alignment plates 43 is adjusted to facilitate alignment and shearing of plates of different widths.

[0040] like Fig.11 As shown, a spring pressing assembly 45 is also fixed on the connecting plate 4, and the spring pressing assembly 45 is used to prevent the cutter 5 from rising and causing the plate to tilt.
