A device for detecting the shearing edge curve of sheet metal in an ultra-large shearing machine

Abstract

This invention discloses a sheet metal shearing edge curve detection device for an ultra-large shearing machine, comprising a frame. The detection component includes a housing fixedly connected to the front side of the frame. A sliding rheostat is fixedly connected to the bottom side of the housing, and a lever is slidably connected to the upper side of the rheostat. A moving rod is fixedly connected to the rear side of the lever, penetrating and extending into the housing. A second roller is rotatably connected to the rear end of the moving rod. This ultra-large shearing machine sheet metal shearing edge curve detection device works by having the edge of the sheet metal contact the second roller. The curve of the sheet metal edge is caused by the moving rod driving the lever to slide on the sliding rheostat, thereby changing the internal resistance value of the rheostat.

This structure achieves the effect of automatically detecting the shearing edge curve and providing accurate detection data.

Description

Technical Field

[0001] This invention relates to the field of curve detection equipment technology, specifically to a device for detecting the curve of the shearing edge of a large-scale shearing machine. Background Technology

[0002] A shearing machine is a machine that uses one blade to reciprocate linearly relative to another blade to cut sheet metal. The shearing quality of a shearing machine is related to many factors, and after the shearing machine has processed the sheet metal, the cut edges of the sheet metal need to be inspected for quality.

[0003] Currently, most shearing machines on the market suffer from several problems. First, after shearing the sheet metal, the flatness of the cut surface requires manual inspection, leading to low efficiency and inaccurate data. Second, while some machines can automatically detect edge curves, the sheet metal still needs to be manually aligned to the center, resulting in significant errors. Third, the sheet metal is not often fixed during inspection, allowing it to move due to external factors, further compromising inspection results. Fourth, the sheet metal may fall too quickly and impact the ground, causing damage. These issues contribute to the problems of manual inspection, low efficiency, inaccurate data, the need for manual alignment, large errors, lack of sheet metal fixation, potential movement due to external factors, poor inspection results, and the risk of impact and damage. Summary of the Invention

[0004] The purpose of this invention is to provide a detection device for the shearing edge curve of a large-scale shearing machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a detection device for the shearing edge curve of a super-large shearing machine, comprising a frame, the left side of which is fixedly connected to a material feeding channel via a connecting block, the bottom inner surface of which is provided with a plurality of evenly distributed stepped grooves, a transport component rotatably connected to the inner side of the frame, the right side of which is fixedly connected to an alignment component via a rectangular block, and detection components penetratingly connected to both the front and rear sides of the frame, wherein two sets of detection components are symmetrically arranged about the front and rear sides of the frame;

[0006] The detection assembly includes a housing fixedly connected to the front side of the frame. A sliding rheostat is fixedly connected to the bottom side of the housing. A lever is slidably connected to the upper side of the rheostat. A moving rod is fixedly connected to the rear side of the lever. The moving rod passes through and extends into the housing. The curve of the edge surface of the plate moves the lever on the rheostat via the moving rod, thereby changing the internal resistance of the rheostat. The computer system can then obtain the data of the sheared edge curve through the changed resistance value. This structure achieves the effect of automatically detecting the sheared edge curve and accurate detection data. A second spring is sleeved on the outer side of the moving rod, and a second roller is rotatably connected to the rear end of the moving rod.

[0007] Furthermore, the transport assembly includes a drive shaft rotatably connected to the front and rear inner walls of the frame. The drive shaft is symmetrically arranged about the left and right sides of the frame. A conveyor belt is rotatably connected to the outer side of the drive shaft, and a plurality of evenly distributed suction cylinders are connected through the inner side of the conveyor belt.

[0008] Furthermore, a ventilation block is fixedly connected to the upper inner wall of the suction cylinder. The ventilation block has evenly distributed through holes. Because of these evenly distributed through holes, the center of the suction cylinder generates suction on the material. Simultaneously, because the outer edge of the suction cylinder has several evenly distributed suction holes, the outer edge of the suction cylinder also generates suction on the material. The combined effect of these two factors allows the material to be fixed and smoothly conveyed to the right. This structure effectively fixes the material, prevents movement due to external factors, and achieves excellent detection results. The upper part of the suction cylinder has evenly distributed suction holes axially distributed.

[0009] Furthermore, the suction hole is connected to the inner wall of the suction cylinder. The lower inner part of the suction cylinder is fixedly connected to the motor via a connecting frame. The upper side of the motor is fixedly connected to the fan blades via a rotating shaft. Activating the external drive device drives the drive shaft to rotate, causing the conveyor belt outside the drive shaft to rotate in a ring. Simultaneously, the motor is activated, causing it to drive the fan blades to rotate via the rotating shaft, thereby generating a downward airflow. The rotating shaft and the motor are rotatably connected.

[0010] Furthermore, the alignment assembly includes a feeding channel fixedly connected to the left side of the frame via a connecting block. Several evenly distributed first rollers are rotatably connected to the bottom inner side of the feeding channel. The operator manually feeds the sheet material into the inner side of the feeding channel until it contacts the first rollers. The first rollers then roll, making it easier to push the sheet material in. Simultaneously, the telescopic rods on both sides are activated, driving the push rod to move inward synchronously, causing the push rod to move the sheet material to the center position. This structure achieves the effects of effortless sheet material pushing and automated alignment. The bottom side of the feeding channel has rectangular grooves corresponding to the first rollers.

[0011] Furthermore, the front and rear sides of the right side of the frame are fixedly connected to the telescopic rod by a fixed rod. The telescopic rod passes through and extends into the interior of the feeding channel. The front sides of the feeding channel are provided with through slots corresponding to the telescopic rod.

[0012] Furthermore, a second contact point is fixedly connected to the center of the front side of the telescopic rod. When the first contact point contacts the second contact point, the external reset switch of the telescopic rod is triggered, causing the telescopic rod to drive the push rod to reset, thereby preventing the telescopic rod from being pushed too far and causing deformation of the sheet metal. This structure achieves the effect of preventing sheet metal deformation. A push rod is slidably connected to the front side of the telescopic rod and to the front side of the second contact point.

[0013] Furthermore, a first spring is axially sleeved between the push rod and the front end face of the second spring. While the push rod pushes the plate, when the plate moves to the center position, the plate's reaction force acts on the push rod, compressing the first spring. This causes the push rod to move the first contact point outwards. The first contact point, the second contact point, and the telescopic rod are electrically connected. The rear end face of the push rod is fixedly connected to the first contact point, and the first and second contacts correspond to each other.

[0014] After the board is inspected, it moves to the material drop channel under the action of the conveyor belt and slides into the inside of the material drop channel. Because there are several evenly distributed stepped grooves on the bottom side of the inside of the material drop channel, the stepped grooves can slow down the board when it falls by its own weight, thereby preventing the board from falling too fast and hitting the ground violently. This structure achieves the effect of preventing the board from falling too fast and preventing the board from being damaged.

[0015] Compared with the prior art, the present invention provides a detection device for the shearing edge curve of sheet metal in an ultra-large shearing machine, which has the following beneficial effects:

[0016] 1. The sheet metal shearing edge curve detection device of this ultra-large shearing machine allows the operator to manually feed the sheet metal into the inner side of the feeding channel and into contact with the first roller. The first roller then rolls, making it easier to push the sheet metal in. At the same time, the telescopic rods on both sides are activated, driving the push rod to move inward synchronously, so that the push rod pushes the sheet metal to the center position. This structure achieves the effects of saving effort when pushing the sheet metal in and automatically aligning it to the center position.

[0017] 2. The sheet metal shearing edge curve detection device of this ultra-large shearing machine pushes the sheet metal with a push rod. When the sheet metal moves to the center position, the reverse force of the sheet metal acts on the push rod, thereby compressing the first spring. This causes the push rod to drive the first contact point outward. Since the first contact point, the second contact point, and the telescopic rod are electrically connected, when the first contact point and the second contact point come into contact, the external reset switch of the telescopic rod is triggered, causing the telescopic rod to drive the push rod to reset. This prevents the sheet metal from deforming due to excessive pushing of the telescopic rod. This structure achieves the effect of preventing sheet metal deformation.

[0018] 3. The sheet metal shearing edge curve detection device of this ultra-large shearing machine uses a conveyor belt on the outside of the drive shaft to rotate in a ring. At the same time, the motor is started, which drives the fan blades to rotate through the shaft, thereby generating a downward airflow. Because the ventilation block has several evenly distributed through holes, the center of the suction cylinder generates suction on the sheet metal. At the same time, because the outer edge of the suction cylinder has several evenly distributed suction holes, the outer edge of the suction cylinder also generates suction on the sheet metal. With the cooperation of these two, the sheet metal can be fixed and smoothly conveyed to the right. This structure achieves the purpose of effectively fixing the sheet metal, preventing the sheet metal from moving due to external factors, and providing excellent detection results.

[0019] 4. The ultra-large shearing machine's sheet metal shearing edge curve detection device uses a suction cylinder and conveyor belt to transport the sheet metal to the right. Then, the edge side of the sheet metal contacts the second roller, which pushes the second roller to drive the moving rod to compress the second spring. The curve of the sheet metal edge surface is driven by the moving rod to move the dial on the sliding rheostat, thereby changing the internal resistance value of the sliding rheostat. The computer system can then obtain the shearing edge curve data through the change in resistance value. This structure achieves the effect of automatically detecting the shearing edge curve and accurately detecting the data.

[0020] 5. The shearing edge curve detection device of this ultra-large shearing machine detects the material as it moves to the dropping channel under the action of the conveyor belt and slides into the inside of the dropping channel. Because the bottom side of the dropping channel has several evenly distributed stepped grooves, the stepped grooves can slow down the material when it falls under its own weight, thereby preventing the material from falling too fast and colliding violently with the ground. This structure achieves the effect of preventing the material from falling too fast and preventing the material from being damaged. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0031] Please see Figure 1-8 A device for detecting the shearing edge curve of a super-large shearing machine includes a frame 1. The left side of the frame 1 is fixedly connected to the material drop channel 2 via a connecting block. The bottom inner surface of the material drop channel 2 is provided with several evenly distributed stepped grooves 3. The inner side of the frame 1 is rotatably connected to a transport component 4. The right side of the frame 1 is fixedly connected to an alignment component 5 via a rectangular block. Detection components 6 are connected through the front and rear sides of the frame 1. Two sets of detection components 6 are symmetrically arranged about the front and rear sides of the frame 1.

[0032] The detection assembly 6 includes a housing 61 fixedly connected to the front side of the frame 1. A sliding rheostat 62 is fixedly connected to the bottom side of the housing 61. A lever 63 is slidably connected to the upper side of the sliding rheostat 62. A moving rod 64 is fixedly connected to the rear side of the lever 63. The moving rod 64 passes through and extends into the interior of the housing 61. The curve of the edge surface of the plate is driven by the moving rod 64 to slide the lever 63 on the sliding rheostat 62, thereby changing the internal resistance value of the sliding rheostat 62. The computer system can then obtain the data of the shearing edge curve through the changed resistance value. This structure achieves the effect of automatically detecting the shearing edge curve and accurate detection data. A second spring 65 is sleeved on the outer side of the moving rod 64, and a second roller 66 is rotatably connected to the rear end of the moving rod 64.

[0033] Furthermore, the transport component 4 includes a drive shaft 41 that is rotatably connected to the front and rear inner walls of the frame 1. The drive shaft 41 is symmetrically arranged about the left and right sides of the frame 1. A conveyor belt 42 is rotatably connected to the outer side of the drive shaft 41. A plurality of evenly distributed suction cylinders 43 are connected through the inner side of the conveyor belt 42.

[0034] Furthermore, a ventilation block 44 is fixedly connected to the upper inner wall of the suction cylinder 43. The ventilation block 44 has evenly distributed through holes 45. Because the ventilation block 44 has several evenly distributed through holes 45, the center of the suction cylinder 43 generates suction on the board. Simultaneously, because the outer edge of the suction cylinder 43 has several evenly distributed suction holes 46, the outer edge of the suction cylinder 43 also generates suction on the board. With the cooperation of both, the board can be fixed and smoothly conveyed to the right. This structure achieves the purpose of effectively fixing the board, preventing board movement due to external factors, and ensuring excellent detection results. The upper part of the suction cylinder 43 has evenly distributed suction holes 46 axially distributed.

[0035] Furthermore, the suction port 46 is connected to the inner wall of the suction cylinder 43. The lower inner part of the suction cylinder 43 is fixedly connected to the motor 48 via a connecting bracket. The upper side of the motor 48 is fixedly connected to the fan blade 47 via a rotating shaft. When the external drive device is activated, it drives the drive shaft 41 to rotate, causing the conveyor belt 42 outside the drive shaft 41 to rotate in a ring. At the same time, the motor 48 is activated, causing the motor 48 to drive the fan blade 47 to rotate via the rotating shaft, thereby generating a downward airflow. The rotating shaft and the motor 48 are rotatably connected.

[0036] Furthermore, the alignment component 5 includes a feeding channel 51 fixedly connected to the left side of the frame 1 via a connecting block. Several evenly distributed first rollers 52 are rotatably connected to the bottom inner side of the feeding channel 51. The operator manually feeds the sheet material into the inner side of the feeding channel 51, where it contacts the first rollers 52. The first rollers 52 then roll, making it easier to push the sheet material in. Simultaneously, the telescopic rods 56 on both sides are activated, causing the push rods 53 to move inward synchronously, pushing the sheet material to the center position. This structure achieves the effects of effortless sheet material insertion and automated alignment. Rectangular grooves corresponding to the first rollers 52 are formed on the bottom side of the feeding channel 51.

[0037] Furthermore, the front and rear sides of the right side of the frame 1 are fixedly connected to the telescopic rod 56 by a fixed rod. The telescopic rod 56 passes through and extends into the interior of the feed channel 51. The front sides of the feed channel 51 are provided with through slots corresponding to the telescopic rod 56.

[0038] Furthermore, a second contact 57 is fixedly connected to the center of the front side of the telescopic rod 56. When the first contact 55 contacts the second contact 57, the external reset switch of the telescopic rod 56 is triggered, causing the telescopic rod 56 to drive the push rod 53 to reset, thereby preventing the telescopic rod 56 from being pushed too far and causing deformation of the plate. This structure achieves the effect of preventing plate deformation. The push rod 53 is slidably connected to the front side of the telescopic rod 56 and to the front side of the second contact 57.

[0039] Furthermore, a first spring 54 is axially sleeved between the push rod 53 and the front end face of the second spring 65. While the push rod 53 pushes the plate, when the plate moves to the center position, the reverse force of the plate acts on the push rod 53, thereby compressing the first spring 54. This causes the push rod 53 to drive the first contact 55 outward. The first contact 55, the second contact 57, and the telescopic rod 56 are electrically connected. The rear end face of the push rod 53 is fixedly connected to the first contact 55, and the first contact 55 and the second contact 57 correspond to each other.

[0040] After the board is inspected, it moves to the material drop channel 2 under the action of the conveyor belt 42 and slides into the inside of the material drop channel 2. Since there are several evenly distributed stepped grooves 3 on the bottom side of the inside of the material drop channel 2, the stepped grooves 3 can decelerate the board when it falls by its own weight, thereby preventing the board from falling too fast and violently impacting the ground. This structure achieves the effect of preventing the board from falling too fast and preventing the board from being damaged.

[0041] The specific usage and function of this embodiment are as follows:

[0042] In use, after the sheet material is sheared by the shearing machine, the operator manually feeds the sheet material into the inner side of the feeding channel 51 and into contact with the first roller 52. Then the first roller 52 rolls, making it easier to push the sheet material in. At the same time, the telescopic rods 56 on both sides are activated to drive the push rod 53 to move inward synchronously, so that the push rod 53 pushes the sheet material to the center position. This structure achieves the effect of saving effort when pushing the sheet material in and automatically aligning it to the center position.

[0043] Furthermore, while the push rod 53 pushes the plate, when the plate moves to the center position, the reverse force of the plate acts on the push rod 53, thereby compressing the first spring 54. This causes the push rod 53 to drive the first contact 55 to move outward. Since the first contact 55, the second contact 57 and the telescopic rod 56 are electrically connected, when the first contact 55 and the second contact 57 come into contact, the external reset switch of the telescopic rod 56 is triggered, causing the telescopic rod 56 to drive the push rod 53 to reset. This prevents the telescopic rod 56 from pushing too much and causing the plate to deform. This structure achieves the effect of preventing the plate from deforming.

[0044] Furthermore, the external drive device is then activated to rotate the drive shaft 41, causing the conveyor belt 42 on the outside of the drive shaft 41 to rotate in a ring. At the same time, the motor 48 is activated, causing the fan blades 47 to rotate through the shaft, thereby generating a downward airflow. Since the ventilation block 44 has several evenly distributed through holes 45, the center of the suction cylinder 43 generates suction on the board. At the same time, since the outer edge of the suction cylinder 43 has several evenly distributed suction holes 46, the outer edge of the suction cylinder 43 also generates suction on the board. With the cooperation of the two, the board can be fixed and smoothly transported to the right. This structure achieves the purpose of effectively fixing the board, preventing the board from moving due to external factors, and ensuring good detection results.

[0045] Furthermore, the suction cylinder 43 and the conveyor belt 42 transport the plate to the right, and then the edge side of the plate comes into contact with the second roller 66, thereby pushing the second roller 66 to drive the motion rod 64 to compress the second spring 65. The curve of the edge surface of the plate is driven by the motion rod 64 to drive the toggle block 63 to slide on the sliding rheostat 62, thereby changing the internal resistance value of the sliding rheostat 62. Then, the computer system can obtain the data of the sheared edge curve through the change in resistance value. This structure achieves the effect of automatically detecting the sheared edge curve and accurate detection data.

[0046] Furthermore, after the board is inspected, the board moves to the dropping channel 2 under the action of the conveyor belt 42 and slides into the interior of the dropping channel 2. Since the bottom side of the interior of the dropping channel 2 is provided with several evenly distributed stepped grooves 3, the stepped grooves 3 can decelerate the board when it falls by its own weight, thereby preventing the board from falling too fast and violently impacting the ground. This structure achieves the effect of preventing the board from falling too fast and preventing the board from being damaged.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
