The bracket body is uniformly and repeatedly heated by the back and forth movement to ensure that the temperature of the bracket body is raised to a level where it can be bent. In this way, the bracket body is heated to improve its toughness to avoid irreversible hard deformation damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] like Figure 1-7 As shown, a bending and forming device for an LED filament bracket comprises a plurality of arc-shaped pressing dies 1 and a bracket body 11. The bracket body 11 is arranged below the arc-shaped pressing dies 1. The plurality of arc-shaped pressing dies 1 are spliced ​​together to form a lower pressing die in the shape of an entire arc. The plurality of arc-shaped pressing dies 1 are fixed together by steel rods, and the steel rods are symmetrically distributed with the lowest point of the arc-shaped pressing dies 1 as the symmetrical point, so as to ensure the stability of the assembled arc-shaped pressing dies 1. A heat conducting plate is left between two adjacent arc-shaped pressing dies 1. Groove 5, a buffer pressure block 6 is provided in the heat-conducting groove 5, and an elastic plastic pressure block 10 is provided at the bottom of the buffer pressure block 6. A buffer spring 4 is provided on the side of the buffer pressure block 6 close to the center of the circle corresponding to the arc-shaped pressing mold 1, and the other end of the buffer spring 4 is fixed on the side of the center rod 2. The curvature of the bottom edge of the buffer pressure block 6 is the same as the curvature of the arc-shaped pressing mold 1, and when the arc-shaped pressing mold 1 and the buffer pressure block 6 move downward, the bottom edge of the buffer pressure block 6 contacts the bracket body 11 before the bottom edge of the arc-shaped pressing mold 1.

[0028] More specifically, during use, when the bracket body 11 is lifted upward, as the bracket body 11 contacts the lower pressing mold composed of the arc-shaped pressing mold 1 more deeply, the part of the bracket body 11 that initially contacts the arc-shaped pressing mold 1 begins to bend until the bending degree of both sides of the bracket body 11 reaches the requirement. At this time, the upper side of the bracket body 11 is completely in contact with the bottom edge of the arc-shaped pressing mold 1, thereby completing the bending process of the bracket body 11. During the bending process, a buffer spring 4 is provided to buffer the bending action. As the bracket body 11 and the arc-shaped pressing mold 1 continue to fit, the buffer pressure block 6 is continuously squeezed upward to avoid hard bending during the bending process and to avoid the bracket body 11 from breaking. By increasing the friction between the bracket body 11 and the arc-shaped pressing mold 1 with the elastic plastic pressure block 10, relative displacement is avoided, and the elastic plastic pressure block 10 can also be used to provide buffering protection for the bracket body 11.

[0029] like Figure 4 and Figure 7 As shown, in some embodiments, a center rod 2 is provided on the concave side of one of the arc-shaped pressing molds 1 located at the center position, and a lifting groove is provided on the center rod 2. A pressure column 3 is provided on the side of the center rod 2 away from the arc-shaped pressing mold 1, and a buffer groove 7 and a guide rod that can slide up and down with the buffer groove 7 are respectively provided on the two symmetrical sides of the pressure column 3. A counterweight groove 9 is provided in the center rod 2, and a counterweight block 8 that slides up and down with the center rod 2 is provided in the counterweight groove 9. An opening for placing the counterweight block 8 is provided at the top of the pressure column 3. By setting the counterweight block 8, counterweight blocks 8 of different weights can be replaced according to different degrees of bending requirements, so that the pressure column 3 can generate different sizes of downward pressure, thereby avoiding deformation damage to the bracket body 11 caused by excessive extrusion due to the pressure column 3 being fixed and improper operation.

[0030] like Figure 3 and Figure 4As shown, in some embodiments, the pressure column 3 is provided with a top plate 43 that can be slidably connected with the pressure column 3 up and down, the guide rod is fixed to the bottom of the top plate 43, and the two symmetrical side surfaces of the top plate 43 are respectively provided with a sliding plug plate 42 that can cooperate with the top plate 43 for sliding insertion, and the sliding plug plate 42 is provided with a placement plate at one end away from the top plate 43, and a hydraulic pump 13 is provided on the placement plate, and the output end of the hydraulic pump 13 is connected to a connecting plate 17 below the placement plate, and a plurality of connecting rods 14 are symmetrically provided on the bottom of the connecting plate 17 with the output axis of the hydraulic pump 13 as the symmetry axis, and the other end of the connecting rod 14 is respectively connected to a plug plate 15, and the plug plate 15 is provided with a docking plate 18 that can cooperate with the plug plate 15 for horizontal sliding insertion, and the plug plate 15 A limiting plate 20 is provided on the upper side, and a fixing spring 16 is provided between the limiting plate 20 and the connecting rod 14. The fixing spring 16 and the limiting plate 20 are provided to ensure that the position of the bracket body 11 can be fixed when the bracket body 11 is placed on the docking plate 18. When the bracket body 11 bends, the bracket body 11 will expand outward around the periphery due to the bending. At this time, the bracket body 11 will automatically open the limiting plate 20, and the presence of the fixing spring 16 can ensure that the bracket body 11 can be in a fixed state at any time. The hydraulic pump 13 is provided to drive the connecting rod 14 and the plug-in plate 15 to rise and fall. During the rising process, the docking plate 18 and the bracket body 11 placed on the docking plate 18 are driven to move upward until the bracket body 11 is fitted with the arc-shaped pressing mold 1.

[0031] like Figure 5 As shown, in some embodiments, the bracket body 11 is arranged above the docking plate 18, and a sliding support 12 is provided on the side where the two adjacent docking plates 18 are away from each other.

A plurality of compression springs 19 are evenly and linearly arranged in the adjustment groove on the upper side of the docking plate 18, and the other end of the compression spring 19 is fixed on the top inner wall of the adjustment groove. By setting the compression spring 19, when the bracket body 11 and the arc-shaped pressing mold 1 are squeezed against each other, the compression spring 19 can drive the docking plate 18 and the bracket body 11 to perform a certain buffering lifting movement in the longitudinal direction, thereby avoiding the bracket body 11 from being plastically bent with the arc-shaped pressing mold 1 at the beginning, thereby producing a certain buffering protection effect on the bracket body 11.

The connecting shaft passes through the lifting slot and the other end of the connecting shaft is connected to the heating mechanism. The first driving gear 35, the arc plate 37 and the guide rod 39 are driven to rotate by the working motor 33. When the arc plate 37 rotates in the semicircular groove, the guide rod 39 is rotated. The positioning rod 39 also rotates. When the arc plate 37 moves to the point where it is about to leave the semicircular groove, the distance between the semicircular groove and the vertical guide groove 38 is set. At this time, the positioning rod 39 just falls into the vertical guide groove 38, and the rotation of the positioning rod 39 in the vertical guide groove 38 drives the transmission plate 21 along the sliding guide rail 44 in one direction, thereby completing the position adjustment of the docking plate 18 and the sliding support 12.
