[0031] In this embodiment, the overall appearance of the lifting base 1 and the supporting base 9 is a square structure. The top and bottom of the first telescopic rod 8 are bolted to the surface of the lifting base 1 and the bottom of the supporting base 9 respectively.

[0034] Example 2

[0035] On the basis of Example 1, a preferred embodiment of a support structure for CNC profile bending machine mold processing provided by the utility model is as follows: Figures 1 to 5 As shown, the roller 12 is arranged parallel to one side of the supporting platform 11 , and the top of the roller 12 protrudes from the top surface of the supporting platform 11 .

[0038] In this embodiment, the slide groove 16 and the supporting platform 11 are an integrated structure, and the bottom of the sliding block 15 passes through the slide groove 16 and is threadedly engaged with the transmission screw 14 .

[0039] In this embodiment, the guide plate 18 is in an arc-shaped structure, and one side of the guide plate 18 is embedded and slidably disposed in an inner groove on the top surface of the support base 9 .

[0040] In this embodiment, the top piston rod of the lifting cylinder 19 protrudes from the top surface of the support base 9 and is bolted to the bottom of the support platform 11. The lifting cylinder 19 is located below the center vertical line of the support platform 11.

[0041] In this embodiment, the support platform 11 and the guide plate 18, according to the setting of the arc slope of the guide plate 18, when the profile enters the top of the support base 9, it is guided by the arc of the guide plate 18 to step onto the top of the roller 12, thereby avoiding damage to the equipment due to deviation between the profile and the movement trajectory. At the same time, through the setting of the slider 15 and the support shaft 17, it is convenient for the profile to maintain its stability when it is spirally bent upward, thereby facilitating the spiral bending of the profile and improving the stability.

[0042] The working principle and use process of the utility model are as follows: first, by rotating the No. 1 handle 2 set on the side surface of the lifting base 1, the power is driven by the transmission shaft 3 to drive the transmission gear 4 to rotate synchronously, and the transmission gear 4 drives the driven gear 5 to start synchronous rotation through the tooth groove meshing connection while rotating, so that the driven screw 6 fixedly connected to the driven gear 5 starts to rotate synchronously, and the top of the driven screw 6 is embedded in the inner middle-range thread of the nut tube 7 and the nut is meshed and connected, the first telescopic rod 8 set between the lifting base 1 and the supporting base 9 limits the rotation of the supporting base 9, so that the thread meshing force between the driven screw 6 and the nut tube 7 becomes an upward or downward force to drive the supporting base 9 to rise or fall. When the surface of the supporting base 9 is on the same horizontal line as the surface of the bending machine, the bending The machine starts to bend the profile. At this time, the lifting cylinder 19 is adjusted to fine-tune the supporting platform 11 up and down to keep the bending data of the bent profile unchanged. At the same time, when the bent profile enters the surface of the guide plate 18, it follows the guide of the guide plate 18 to enter the top of the roller 12. The bent material starts to spiral up through the support of the roller 12. At this time, the transmission screw 14 is driven to rotate by rotating the No. 2 handle 13 to move the slider 15 to the path of the bent profile. At the same time, the supporting shaft 17 is used to prevent the profile from scratching the surface when moving on the top of the slider 15. The slider 15 is also stacked to limit the bending route of the bent profile to avoid left and right swaying due to the weight of the profile itself during upward operation. When the spiral bending of the profile is completed, the profile can be taken out from above the surface of the supporting base 9 and wait for the next profile to undergo spiral bending processing.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
