Description

Technical Field

A correction table is fixed on the support seat, a bottom column is fixed on the side of the correction table, a sleeve shell elastically matched with the bottom column is arranged at the top of the bottom column, and a roller rotatably matched with the sleeve shell is arranged in the sleeve shell. The utility model solves the problem of excessive friction between the product and the correction table by using the dynamic characteristics, making the correction table dynamic and adding rollers on its surface, reducing the contact area between the workpiece and the correction table and the frictional resistance. When the product is placed on the rollers, due to the spring elastic force, the product does not directly contact the correction table, and the product can roll or move. When correcting, the hydraulic press table presses on the product to overcome the spring elastic force, and then the correction can start, and the elastic function of the rollers fails temporarily. When the pressure acting on the product gradually decreases and cannot overcome the spring elastic force, the rollers return to their original state. However, in the process of applying this technical solution, the profiles to be corrected are manually pushed and moved, and there is a technical problem that the profiles before and after correction cannot be automatically conveyed and moved to improve the correction efficiency and reduce the labor intensity of workers.

A return spring 14 is arranged outside the telescopic rods 8. The top end of the return spring 14 is fixedly connected to the bottom end of the second grooves 6, and the bottom end of the return spring 14 is fixedly connected to the top of the platen 1. The telescopic rods 8 can contract when the conduction rollers 7 are pressed to ensure the structural safety of the conduction rollers 7, and after the calibration work is completed, the conduction rollers 7 are pushed back to conduct the profile by the return spring 14;

[0022] As a further implementation manner of this embodiment, as Figure 1 、 Figure 2 and Figure 3 shown, at the middle position of the top of the platen 1, a first groove 3 is provided. Between the two ends inside the first groove 3, a transfer roller 12 is provided. At the front end of the first groove 3, a driving motor 4 is provided. The front end of the transfer roller 12 penetrates through the front end inside the first groove 3 and is fixedly connected to the output end of the driving motor 4. By driving the transfer roller 12 to rotate in the first groove 3 by the driving motor 4, the profile that needs to be calibrated can be transferred and moved. At a position near the middle of the bottom end of the platen 1, a lifting electric cylinder 15 is penetrated. The top end of the lifting electric cylinder 15 is fixedly connected to the middle position of the bottom end of the first groove 3. By driving the first groove 3 to descend by the lifting electric cylinder 15, the transfer roller 12 is lower than the top surface of the calibration seats 2, so as to avoid damage to the transfer assembly when the profile is pressed and calibrated, thereby achieving the effect of conveniently and quickly transferring the profile that needs to be calibrated and reducing the labor intensity of the staff;

[0023] During use, by driving the transfer roller 12 to rotate in the first groove 3 by the driving motor 4, the profile that needs to be calibrated can be transferred and moved, and during the calibration process, the first groove 3 is driven to descend by the lifting electric cylinder 15 so that the transfer roller 12 is lower than the top surface of the calibration seats 2 to avoid damage to the transfer assembly when the profile is pressed and calibrated;

[0024] As a further implementation manner of this embodiment, as Figures 1-4As shown, limiting components are provided at both ends of the top of the calibration base 2. The limiting components include positioning seats 5 in an "L" shape, which are arranged at both ends of the top of the calibration base 2. An adjustment slot 16 is provided at the top end inside the calibration base 2. A connection slot 9 is provided at one end of the positioning seat 5. A limiting roller 13 is arranged between both ends inside the connection slot 9. The limiting roller 13 is used to perform lateral limitation on the profile to be calibrated, avoiding the deviation of the profile during the calibration process and affecting the calibration effect. A connection through-hole 19 is provided at the bottom end inside the positioning seat 5. A through-connection screw 17 penetrates between the inside of the adjustment slot 16 and the connection through-hole 19. The diameter of the through-connection screw 17 is smaller than the internal width of the adjustment slot 16, and the through-connection screw 17 can move within the adjustment slot 16.

[0025] During use, the limiting roller 13 is used to perform lateral limitation on the profile to be calibrated, and the spacing between the positioning seat 5 and the limiting roller 13 can also be adjusted by adjusting the position spacing of the through-connection screw 17 penetrating within the adjustment slot 16 to effectively limit profiles of different widths;

[0026] Specific working principle:

[0027] When using the hydraulic press calibration labor-saving device, first, the position spacing of the through-connection screw 17 penetrating within the adjustment slot 16 will be adjusted according to the size of the profile to be calibrated to adjust the spacing between the positioning seat 5 and the limiting roller 13 to suit the profile to be calibrated. Subsequently, the profile to be calibrated is placed on the calibration base 2 and between the limiting rollers 13. Then, the driving motor 4 is used to drive the conveying roller 12 to rotate within the first trough body 3 to convey and move the profile to be calibrated and positioned, and the conductive roller 7 is used to conduct and move the profile labor-savingly. At the same time, the limiting roller 13 performs lateral limitation on the profile to be calibrated. When the calibration work starts, the calibration hydraulic cylinder 11 is started to press down the profile placed on the calibration base 2, and the lifting electric cylinder 15 is used to drive the first trough body 3 to descend so that the conveying roller 12 is lower than the top surface of the calibration base 2 to avoid damage to the conveying component when the profile is pressed and calibrated. At the same time, the telescopic rod 8 contracts to ensure the structural safety of the conductive roller 7. After the calibration work is completed, the reset spring 14 is used to push the conductive roller 7 to reset and conduct the profile, and the lifting electric cylinder 15 is used to push the conveying roller 12 to rise to conduct and convey the profile, so as to perform efficient and stable profile calibration operations.
