Description

Technical Field

[0001] The invention relates to the technical field of curve detection equipment, in particular to a shearing edge curve detection device for a super-large shearing machine. Background Art

[0002] A shearing machine is a machine that uses one blade to make a reciprocating linear motion relative to another blade to shear the plate. The shearing quality of the shearing machine is related to many factors. After the shearing machine shears the plate, the shearing edge of the plate needs to be inspected for quality.

[0003] The main problem with most shearing machines on the market at present is that after the shearing machine shears the plate, the flatness of the sheared surface needs to be manually inspected, resulting in low inspection efficiency and inaccurate inspection data. Alternatively, a device that can automatically detect the edge curve can be provided, but the plate needs to be manually aligned to the center position for inspection, resulting in large inspection errors. In addition, during the inspection, the plate is not fixed, and the plate may move due to external factors, resulting in poor inspection results. In addition, when the plate falls after inspection, it may fall too fast and hit the ground, causing damage to the plate. The above situations will result in the need for manual inspection, low inspection efficiency, inaccurate inspection data, the need to manually align the center position for inspection, large inspection errors, the plate is not fixed, the plate may move due to external factors, the inspection results are poor, and the plate may fall too fast and hit the ground, causing damage to the plate. Summary of the invention

[0004] The object of the present invention is to provide a device for detecting the shearing edge curve of a plate of an ultra-large shearing machine, so as to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a super-large shearing machine plate shearing edge curve detection device, comprising a frame, the left side of the frame is fixedly connected to the blanking channel through a connecting block, the inner bottom surface of the blanking channel is provided with a plurality of evenly distributed step grooves, the inner side of the frame is rotatably connected with a transport component, the right side of the frame is fixedly connected to an alignment component through a rectangular block, the front and rear sides of the frame are both penetrated and connected with detection components, and the detection components are symmetrically arranged in two groups with respect to the front and rear sides of the frame; The detection assembly includes a shell fixedly connected to the front side of the frame, a sliding rheostat is fixedly connected to the bottom side of the shell, a shift block is slidably connected to the upper side of the sliding rheostat, and a moving rod is fixedly connected to the rear side of the shift block. The moving rod penetrates and extends into the interior of the shell. The curve of the edge surface of the plate drives the shift block to slide on the sliding rheostat through the moving rod, thereby changing the internal resistance value of the sliding rheostat. Then the computer system can obtain the data of the shear edge curve through the changed resistance value. This structure can automatically detect the shear edge curve and detect accurate data. A second spring is sleeved on the axial outer side of the moving rod, and a second roller is rotatably connected to the rear end of the moving rod.

[0006] 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 frame, the outer side of the drive shaft is rotatably connected to a conveyor belt, and the inner side of the conveyor belt is penetrated by a number of evenly distributed suction cylinders.

[0007] Furthermore, the upper inner wall of the suction cylinder is fixedly connected with a ventilation block, and the ventilation block is provided with evenly distributed through holes. Since the ventilation block is provided with several evenly distributed through holes, the center of the suction cylinder generates suction on the plate. At the same time, since the outer edge of the suction cylinder is provided with several evenly distributed suction holes, the outer edge of the suction cylinder also generates suction on the plate. With the cooperation of the two, the plate can be fixed and smoothly transported to the right. This structure can effectively fix the plate, prevent the plate from moving due to external factors, and achieve good detection effect. Evenly distributed suction holes are provided in the upper axial part of the suction cylinder.

[0008] Furthermore, the suction hole is communicated with the inner wall of the suction cylinder, the inner lower part of the suction cylinder is fixedly connected to the motor through a connecting frame, the upper side of the motor is fixedly connected to the fan blades through a rotating shaft, the external driving device is started to drive the driving shaft to rotate, so that the conveyor belt outside the driving shaft rotates in a circular manner, and at the same time, the motor is started, so that the motor drives the fan blades to rotate through the rotating shaft, thereby generating wind force from top to bottom. The rotating shaft and the motor are rotatably connected.

[0009] Furthermore, the alignment component includes a feed channel fixedly connected to the left side of the frame through a connecting block, and the inner bottom side of the feed channel is rotatably connected to a plurality of evenly distributed first rollers. The staff manually feeds the plate into the inner side of the feed channel to contact the first roller, and then the first roller rolls, making it easier to push the plate in. At the same time, the telescopic rods on both sides are started to drive the push rods to move inward synchronously, so that the push rods push the plate to the center position. This structure achieves the effect of saving effort in pushing the plate in and aligning the center position automatically. A rectangular groove corresponding to the first roller is provided on the bottom side of the feed channel.

[0010] Furthermore, the front and rear side surfaces of the right part of the frame are fixedly connected to the telescopic rod through a fixing rod, the telescopic rod penetrates and extends into the interior of the feed channel, and through grooves corresponding to the telescopic rod are provided on both sides of the front side of the feed channel.

[0011] Furthermore, a second contact is fixedly connected to the center of the front side of the telescopic rod. When the first contact contacts the second contact, the external reset switch of the telescopic rod is triggered, so that the telescopic rod drives the push rod to reset, thereby preventing the telescopic rod from pushing too much and causing the plate to deform. This structure achieves the effect of preventing the plate from deforming. A push rod is slidably connected to the front side of the telescopic rod and in front of the second contact.

[0012] Furthermore, a first spring is axially sleeved between the push rod and the front end surface of the second spring. When the push rod pushes the plate, when the plate moves to the center position, the reverse force of the plate acts on the push rod, thereby compressing the first spring, so that the push rod drives the first contact to move outward. Since the first contact, the second contact and the telescopic rod are electrically connected. The rear end surface of the push rod of the push rod is fixedly connected with the first contact, and the first contact and the second contact correspond to each other.

[0013] After the plate inspection is completed, the plate moves to the blanking channel under the action of the conveyor belt and slides into the interior of the blanking channel. Since a number of evenly distributed step grooves are opened on the inner bottom side of the blanking channel, the step grooves can slow down the plate when it falls by its own gravity, thereby preventing the plate from colliding violently with the ground at too fast a speed. This structure achieves the effect of preventing the plate from falling too fast and preventing the plate from being damaged.

[0014] Compared with the prior art, the present invention provides a device for detecting the shearing edge curve of a super-large shearing machine, which has the following beneficial effects: 1. The shearing edge curve detection device of the super-large shearing machine is that the staff manually feeds the plate into the inner side of the feeding channel to contact with the first roller, and then the first roller rolls, making it easier to push the plate in. At the same time, the telescopic rods on both sides are started to drive the push rods to move inward synchronously, so that the push rods push the plate to the center position. This structure achieves the effect of saving effort in pushing the plate and automatically aligning the center position.

[0015] 2. The shearing edge curve detection device of the super-large shearing machine pushes the plate through the pushing rod. When the plate moves to the center position, the reverse force of the plate acts on the pushing rod, thereby compressing the first spring, so that the pushing rod drives the first contact to move outward. Since the first contact, the second contact and the telescopic rod are electrically connected, when the first contact contacts the second contact, the external reset switch of the telescopic rod is triggered, so that the telescopic rod drives the pushing rod to reset, thereby preventing the telescopic rod from pushing too much and causing deformation of the plate. This structure achieves the effect of preventing deformation of the plate.

[0016] 3. The shearing edge curve detection device of the super-large shearing machine drives the conveyor belt on the outside of the shaft to rotate in a circle, and at the same time, the motor is started, so that the motor drives the fan blades to rotate through the shaft, thereby generating wind force from top to bottom. Since the ventilation block is provided with a number of evenly distributed through holes, the center position of the suction cylinder generates suction on the plate. At the same time, since the outer edge of the suction cylinder is provided with a number of evenly distributed suction holes, the outer edge of the suction cylinder also generates suction on the plate. With the cooperation of the two, the plate can be fixed and transported smoothly to the right. This structure can effectively fix the plate, prevent the plate from moving due to external factors, and achieve good detection effect.

[0017] 4. The shearing edge curve detection device of the super-large shearing machine transports the plate to the right through the suction cylinder and the conveyor belt, and then the edge side of the plate contacts the second roller, thereby pushing the second roller to drive the moving rod to compress the second spring, and the curve of the edge surface of the plate drives the shift block to slide on the sliding rheostat through the moving rod, thereby changing the internal resistance value of the sliding rheostat, and then the computer system can obtain the data of the shearing edge curve through the changed resistance value. This structure can automatically detect the shearing edge curve and detect the data accurately.

[0018] 5. The shearing edge curve detection device of the super-large shearing machine moves the plate to the blanking channel under the action of the conveyor belt and slides into the inside of the blanking channel. Since a number of evenly distributed step grooves are opened on the inner bottom side of the blanking channel, the step grooves can slow down the plate when it falls by its own gravity, thereby preventing the plate from colliding violently with the ground at too fast a speed. This structure achieves the effect of preventing the plate from falling too fast and preventing the plate from being damaged. BRIEF DESCRIPTION OF THE DRAWINGS

The moving rod 64 penetrates and extends into the interior of the housing 61. The curve of the edge surface of the plate drives the shift block 63 to slide on the sliding rheostat 62 through the moving rod 64, thereby changing the internal resistance value of the sliding rheostat 62. Then, the computer system can obtain the data of the shear edge curve through the changed resistance value. This structure can automatically detect the shear edge curve and accurately detect the data. A second spring 65 is sleeved on the axial outer side of the moving rod 64, and a second roller 66 is rotatably connected to the rear end of the moving rod 64.

[0024] Furthermore, the transport assembly 4 includes a drive shaft 41 rotatably connected to the front and rear inner walls of the frame 1. The drive shaft 41 is symmetrically arranged about the frame 1. The outer side surface of the drive shaft 41 is rotatably connected to a conveyor belt 42. The inner side of the conveyor belt 42 is penetrated by a plurality of evenly distributed suction cylinders 43.

[0025] Furthermore, the upper inner wall of the suction cylinder 43 is fixedly connected with a ventilation block 44, and the ventilation block 44 is provided with evenly distributed through holes 45. Since the ventilation block 44 is provided with several evenly distributed through holes 45, the center of the suction cylinder 43 generates suction on the plate. At the same time, since the outer edge of the suction cylinder 43 is provided with several evenly distributed suction holes 46, the outer edge of the suction cylinder 43 also generates suction on the plate. With the cooperation of the two, the plate can be fixed and smoothly transported to the right. This structure can effectively fix the plate, prevent the plate from moving due to external factors, and achieve good detection effect. The upper part of the suction cylinder 43 is axially provided with evenly distributed suction holes 46.

[0026] Furthermore, the suction hole 46 is connected to the inner wall of the suction cylinder 43, and the inner lower part of the suction cylinder 43 is fixedly connected to the motor 48 through a connecting frame. The upper side of the motor 48 is fixedly connected to the fan blade 47 through a rotating shaft. The external driving device is started to drive the driving shaft 41 to rotate, so that the conveyor belt 42 outside the driving shaft 41 rotates in a circular manner. At the same time, the motor 48 is started, so that the motor 48 drives the fan blade 47 to rotate through the rotating shaft, thereby generating wind force from top to bottom. The rotating shaft and the motor 48 are rotatably connected.

[0027] Furthermore, the alignment component 5 includes a feed channel 51 fixedly connected to the left side of the frame 1 through a connecting block, and a plurality of evenly distributed first rollers 52 are rotatably connected to the inner bottom side of the feed channel 51. The staff manually feeds the plate into the inner side of the feed channel 51 to contact the first roller 52, and then the first roller 52 rolls, making it easier to push the plate in. At the same time, the telescopic rods 56 on both sides are started to drive the push rod 53 to move inward synchronously, so that the push rod 53 pushes the plate to the center position. This structure achieves the effect of saving effort in pushing the plate in and aligning the center position automatically. A rectangular groove corresponding to the first roller 52 is opened on the bottom side of the feed channel 51.

[0028] Furthermore, the front and rear sides of the right part of the frame 1 are fixedly connected to the telescopic rod 56 through a fixing rod, and the telescopic rod 56 penetrates and extends into the interior of the feed channel 51. Both sides of the front side of the feed channel 51 are provided with through grooves corresponding to the telescopic rod 56.

[0029] Furthermore, a second contact 57 is fixedly connected to the front center 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, so that the telescopic rod 56 drives the push rod 53 to reset, thereby preventing 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. The push rod 53 is slidably connected to the front side of the telescopic rod 56 and in front of the second contact 57.

[0030] Furthermore, the first spring 54 is axially sleeved between the push rod 53 and the front end surface of the second spring 65. When 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, so that the push rod 53 drives the first contact 55 to move outward. Since the first contact 55, the second contact 57 and the telescopic rod 56 are electrically connected, the rear end surface of the push rod 53 is fixedly connected with the first contact 55, and the first contact 55 and the second contact 57 correspond to each other.

[0031] After the plate inspection is completed, the plate moves to the blanking channel 2 under the action of the conveyor belt 42 and slides into the interior of the blanking channel 2. Since a number of evenly distributed step grooves 3 are provided on the inner bottom side of the blanking channel 2, the step grooves 3 can decelerate the plate when it falls by its own gravity, thereby preventing the plate from colliding violently with the ground at too fast a speed. This structure achieves the effect of preventing the plate from falling too fast and preventing the plate from being damaged.

[0032] The specific usage and function of this embodiment are as follows: When in use, first, after the plate is sheared by the shearing machine, the staff manually feeds the plate into the inner side of the feeding channel 51 to contact the first roller 52, and then the first roller 52 rolls, making it easier to push the plate in. At the same time, the telescopic rods 56 on both sides are started to drive the pushing rod 53 to move inward synchronously, so that the pushing rod 53 pushes the plate to the center position. This structure achieves the effect of saving effort in pushing the plate in and automatically aligning the center position.

[0033] 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, so that the push rod 53 drives 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 contacts the second contact 57, the external reset switch of the telescopic rod 56 is triggered, so that the telescopic rod 56 drives the push rod 53 to reset, thereby preventing the telescopic rod 56 from pushing too much and causing deformation of the plate. This structure achieves the effect of preventing deformation of the plate.

[0034] Furthermore, the external driving device is subsequently started to drive the driving shaft 41 to rotate, so that the conveyor belt 42 outside the driving shaft 41 rotates in a circle, and at the same time, the motor 48 is started, so that the motor 48 drives the fan blades 47 to rotate through the rotating shaft, thereby generating a wind force from top to bottom. Since the ventilation block 44 is provided with a number of evenly distributed through holes 45, the center position of the suction cylinder 43 generates suction on the plate. At the same time, since the outer edge of the suction cylinder 43 is provided with a number of evenly distributed suction holes 46, the outer edge of the suction cylinder 43 also generates suction on the plate. With the cooperation of the two, the plate can be fixed and transported smoothly to the right. This structure can effectively fix the plate, prevent the plate from moving due to external factors, and achieve good detection effect.

[0035] Furthermore, the plate is transported to the right through the suction cylinder 43 and the conveyor belt 42, and then the edge side of the plate contacts the second roller 66, thereby pushing the second roller 66 to drive the moving rod 64 to compress the second spring 65. The curve of the edge surface of the plate drives the shift block 63 to slide on the sliding rheostat 62 through the moving rod 64, thereby changing the internal resistance of the sliding rheostat 62, and then the computer system can obtain the data of the shear edge curve through the changed resistance. This structure can automatically detect the shear edge curve and accurately detect the data.

[0036] Furthermore, when the plate inspection is completed, the plate moves to the blanking channel 2 under the action of the conveyor belt 42 and slides into the interior of the blanking channel 2. Since a number of evenly distributed step grooves 3 are provided on the inner bottom side of the blanking channel 2, the step grooves 3 can decelerate the plate when it falls by its own gravity, thereby preventing the plate from colliding violently with the ground at too fast a speed. This structure achieves the effect of preventing the plate from falling too fast and preventing the plate from being damaged.
