Description

Technical Field

[0001] This application relates to the technical field of shearing the sides of plates, and particularly to a turning device for trimming large-area plates. Background Art

[0002] Metal plates are usually formed by rolling ingot-shaped billets melted and refined. After rolling, there are rolling defects such as uneven plate thickness and curved side edges at each side of the plate. During the later reprocessing of the plate, the sides of the plate are usually sheared off to achieve the regularity of the plate sides.

[0003] Currently, when trimming the edges of blank plates, a trimming machine is usually used to perform the trimming operation. The specific operation method is to turn the plate onto the plate shearing platform of the trimming machine, and then manually push the plate to move on the plate shearing platform, so that one side edge of the plate extends under the blade of the trimming machine, and a trimming operation with a certain width of the plate side is achieved through the blade of the trimming machine. After the trimming is completed, the plate is manually pulled out to the outside of the blade of the trimming machine.

[0004] After one side of the plate is trimmed, when trimming other sides, the plate placed on the trimming machine is usually rotated manually, so that another side of the plate corresponds to the blade of the trimming machine, and the side to be trimmed of the plate is pushed again to extend under the blade for trimming. In this way, the four sides of the plate are completely trimmed.

[0005] The difficulties in trimming the sides of the plate currently include:

[0006] 1. When the plate is large in size, due to the increase in the weight of the metal plate, it is difficult for the operator to lift and hold the side of the plate, and it is easy to crush the fingers. In addition, when the plate is rotated, the operator usually squats on the plate shearing platform. It is not only difficult to perform the rotation operation, but also there are safety hazards when standing at a high position and the operation space is small;

[0007] 2. Since the plate is in flat contact with the plate shearing platform, there is a large rotational friction when the plate is rotated. Therefore, it is difficult for the operator to quickly and safely rotate the plate under the double resistance of the weight of the plate and the rotational friction, which further increases the shearing operation time of the plate side. Summary of the Invention

[0008] Aiming at the above problems, this application aims to provide a turning device for trimming large-area plates, which solves the great difficulties and safety hazards existing in the current manual turning of plates, thereby improving the operation efficiency of plate trimming.

[0009] To achieve the above object, the technical solution adopted in the present application is as follows: A turning device for trimming large-area plates, characterized in that: the turning device includes a plate turning platform at the same height as the plate shearing platform of the trimming machine, a rotary support mechanism is provided at the bottom of the plate turning platform, and a driving mechanism for driving the plate forward and backward onto the plate shearing platform is provided on the plate turning platform.

[0010] Preferably, the rotary support mechanism includes a rotating table provided at the center of the bottom surface of the plate turning platform, and a support contacting the ground is provided at the bottom of the rotating table.

[0011] Preferably, a spring telescopic rod is provided on the rotating table, and positioning grooves for embedding the spring telescopic rod are respectively opened at the quadrant positions of the bottom surface of the plate turning platform.

[0012] Preferably, the driving mechanism includes rotating spheres embedded and evenly distributed on the plate turning platform.

[0013] Preferably, horizontal and vertical limiting plates are respectively hinged at the four corners of the plate turning platform, and torsion springs for driving them to be perpendicular to the surface of the plate turning platform are provided at the hinge joints of each limiting plate.

[0014] The beneficial effect of the present application is that: the turning device can realize the rapid turning of each side of the plate through the plate turning platform and correspond to the cutting edge of the trimming machine, solve the great difficulty and potential safety hazards existing in the current manual turning of the plate, thereby improving the operation efficiency of plate trimming and ensuring the safety of personnel during operation.

[0025] In order to enable ordinary technicians in the art to better understand the technical solution of the present application, the technical solution of the present application will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Referring to Figures 1-9 A turning device for trimming a large-area sheet shown in the figure. The turning device includes a sheet turning platform 1 that is at the same height as the sheet shearing platform 20 of the trimming machine 10. A rotary support mechanism is provided at the bottom of the sheet turning platform 1. First, the sheet is placed on the sheet shearing platform by turning, and the side of the sheet is pushed into the lower part of the blade of the trimming machine for trimming operation. After the shearing operation is completed, since the sheet turning platform 1 is at the same height as the sheet shearing platform 20, the sheet can be pulled out onto the sheet turning platform 1 (when pulling out the sheet, the operator stands on the ground, which can ensure the safety of the operation). Then, the rotary support mechanism can drive the sheet turning platform 1 to rotate quickly and labor-savingly, that is, adjust the other side of the sheet to be trimmed to correspond to the blade of the trimming machine. Subsequently, the sheet is pushed onto the sheet shearing platform 20 again (when the weight of the sheet body is large, the fork plate of the forklift can be used to contact the outer side of the sheet for mechanical pushing. On the basis of realizing labor-saving operation, the trimming operation can be further accelerated), and the side to be trimmed is extended under the blade, so that the shearing of the side can be realized. Such operation can perform the quick shearing of each side of the sheet, greatly improving the operation efficiency of sheet trimming and ensuring the safety of personnel during operation.

[0027] When pulling the sheet from the sheet shearing platform 20 onto the sheet turning platform 1, it is convenient for the sheet to be quickly shifted onto the sheet turning platform 1. A driving mechanism for driving the sheet forward and backward to the sheet shearing platform 20 is provided on the sheet turning platform 1. After the sheet is pulled out from the sheet shearing platform 20 and enters the sheet turning platform 1 and contacts the driving mechanism, the sheet can be quickly shifted onto the sheet turning platform 1, reducing the shifting friction between the sheet and the surface of the sheet turning platform 1, accelerating the turning operation of the sheet, and further reducing the friction damage to the surface of the sheet.

[0028] Specifically, such asFigure 5 As shown, the rotary support mechanism includes a rotating table 2 provided at the center of the bottom surface of the sheet turning platform 1, and a bracket 3 (with lockable universal wheels at the four corners) in contact with the ground is provided at the bottom of the rotating table 2. The rotating table 2 is a rotating shaft structure provided with bearings, which can drive the sheet turning platform 1 to rotate rapidly relative to the bracket 3, realizing the labor-saving turning operation of the sheet.

[0029] To facilitate the position adjustment of the bracket 3, preferably lockable universal wheels are provided at the four corners of the bracket 3, which can move the whole turning device, and it can be withdrawn to the trimming machine when not in use.

[0030] When rotating through the rotating table 2 with bearings, it has high rotational flexibility. When the sheet is rotated by the sheet turning platform 1 and then pushed to the trimming machine for trimming operation, under the thrust, the sheet turning platform 1 will rotate again due to unequal forces on both sides, resulting in the side edge of the adjusted sheet on it being skewed with the blade of the trimming machine, and it is difficult to adjust the sheet due to the contact friction with the sheet shearing platform. Therefore, to solve this problem, as Figures 5-6 shown, a spring telescopic rod 4 is provided on the rotating table 2, and positioning grooves 1a for embedding the spring telescopic rod 4 are opened at the quadrant positions on the bottom surface of the sheet turning platform 1. When the sheet turning platform 1 rotates, its bottom surface presses the spring telescopic rod 4. When the side edge of the sheet is rotated and adjusted to be parallel to the blade of the trimming machine, at the same time, the spring telescopic rod 4 corresponds to the corresponding positioning groove 1a on the bottom surface of the sheet turning platform 1, and under the action of the spring, the top end of the spring telescopic rod 4 is driven to be embedded in the positioning groove 1a, thereby realizing the limitation of the sheet turning platform 1. At this time, the sheet can be pushed to the trimming machine to realize trimming, solving the problem that the sheet turning platform rotates arbitrarily and causes the sheet to be skewed with the blade of the trimming machine.

[0031] When the sheet turning platform needs to be rotated, the operator drives it to rotate. Preferably, the two sides of the positioning groove 1a and the bottom surface of the sheet turning platform 1 are set to have a slope transition (as Figure 7 shown), that is, the spring telescopic rod 4 can slide out from the side of the positioning groove 1a (the top end of the spring telescopic rod 4 is preferably set to have a spherical head structure, which is convenient for it to slide out from the positioning groove 1a). After sliding out, the rotation of the sheet turning platform 1 can be realized.

[0032] Specifically, as Figures 2-4As shown, the driving mechanism includes rotating spheres 5 embedded and evenly distributed on the plate turning platform 1. After the plate is pulled out from the plate trimming platform 20 and shifted onto the plate turning platform 1, the plate contacts the rotating spheres 5. Under the rolling support of the rotating spheres 5 on the plate, the plate can be quickly shifted onto the plate turning platform 1, and then the rotation of the plate turning platform 1 can be driven, that is, the adjustment of the side of the plate can be realized. At the same time, after the adjustment of the side direction is completed, the plate can be reversely driven to move towards the trimming machine direction on the rotating spheres 5, accelerating the operation efficiency of the plate direction turning operation.

[0033] When the plate contacts the rotating spheres 5, the moving flexibility of the plate is improved. To prevent the plate from extending outside the plate turning platform 1 due to centrifugal force during the rotation adjustment, as Figures 4-5 shown in FIGS. 8-9, horizontal and vertical limiting plates 11 are hingedly arranged at the four corners of the plate turning platform 1, and a torsion spring (not shown in the figure) for driving it to be perpendicular to the surface of the plate turning platform 1 is arranged at the hinge of each limiting plate 11. According to the moving inertia of the plate on the rotating spheres 5, the torque of the torsion spring is set. Under normal circumstances, each limiting plate 11 is kept perpendicular to the surface of the plate turning platform 1 through the torsion spring, and a certain blocking effect is provided for the movement of the plate, avoiding the problems that the side of the plate extends outside the plate turning platform 1 and is likely to contact the operator and slip.

[0034] When the plate direction turning is completed and the plate is driven to move towards the trimming machine direction, the side of the plate contacts the limiting plate 11 and overcomes the acting force of the torsion spring (as Figure 9 shown in the state), and then the plate can be transferred from the plate turning platform 1 to the plate shearing platform 20.

[0035] When the plate enters the plate turning platform 20 from the shearing machine for the side direction turning, the acting force of the torsion spring can be overcome manually, so that the left and right two limiting plates close to the trimming machine are turned downwards. After turning down, the plate can be shifted onto the plate turning platform for the side direction turning operation.

[0036] The principle of this application is as follows: When trimming the edges of a sheet, first place the sheet on the sheet trimming platform by turning it, and then push the side edge of the sheet under the blade of the edge trimmer for edge trimming. After the edge trimming operation on one side is completed, manually overcome the acting force of the torsion spring, so that the left and right two limit plates close to the edge trimmer turn downwards, pull out the sheet, and reach the sheet turning platform 1 under the rolling contact of the rotating sphere 5. Then drive the sheet turning platform 1 to quickly rotate under the rotating structure of the rotating table 2 until the other side edge of the sheet corresponds to the blade of the edge trimmer. At the same time, the spring telescopic rod 4 corresponds to the corresponding positioning groove 1a on the bottom surface of the sheet turning platform 1, and under the action of the spring, drive the top end of the spring telescopic rod 4 to be embedded in the positioning groove 1a, so as to realize the limit of the sheet turning platform 1. At this time, the sheet can be pushed to the edge trimmer to complete the edge trimming. Such an operation can realize the quick turning of each side edge of the sheet and the completion of the edge trimming operation, thus solving the problems of potential safety hazards and low operation efficiency existing in the current manual turning of the sheet.

[0037] The above shows and describes the basic principle, main features and advantages of this application. Without departing from the spirit and scope of this application, this application will also have various changes and improvements, and these changes and improvements all fall within the scope of this application claimed.
