[0016] Compared with the prior art, the present invention provides a municipal sign profile non-cutting forming construction device, which has the following beneficial effects:

[0017] 1. The municipal sign profile has no cutting and forming device. First, the stamping unit drives the first stamping block and the first forming module to stamp the profile into a first shape. When the second shape needs to be stamped, the control and adjustment unit converts it into the second stamping block. During the conversion process, the linkage component drives the pushing unit to descend for the first time.

[0018] Then, the stamping cylinder is controlled to drive the second stamping block to descend and at the same time drive the pushing unit to descend for the second time. The pushing unit will apply thrust to the conversion unit, and the conversion unit will drive the rotating shaft to rotate inward, thereby driving the second forming module to rotate inward, and the side wall of the second forming module contacts the forming position limiting block to form a second form of the second forming module matched with the second stamping block. By utilizing the power of the conversion between the first stamping block and the second stamping block, and reusing the pressure during stamping, the conversion between the first forming module and the second forming module is realized, so that stamping with different needs can be met and the scope of use is expanded;

[0019] 2. The municipal sign profile has no cutting and forming construction device. The second forming module is in the first form. The roller cooperates with the first forming module. When the stamping unit drives the first stamping block to stamp, the first forming module rotates inward, and at the same time drives the roller to rotate inward, and rounds the corners of the stamped profile to avoid material breakage caused by hard chamfering. At the same time, the roller is protruding and will squeeze the corners, so that the corners of the profile after stamping are tightened. When installed on the trapezoidal rod, there is an interference fit and it will not slide at will.

[0020] 3. The municipal sign profile has no cutting and forming construction device. When the second forming module rotates to become the second form, the roller is driven to rotate through the connecting rod. The roller will squeeze the locking protrusion. The upper end surface of the locking protrusion is set to an arc shape. When squeezed from above, it will shrink into the slide groove. When the extrusion is completed, it will reset outward under the influence of thrust spring 1, and cooperate with the forming position limiting block to limit and fix the roller, thereby improving the stability of the second forming module structure in the second form.

[0034] Example 1: Reference Figure 1-Figure 10 A non-cutting forming device for municipal sign profiles includes a stamping seat 5 and a support frame 1. A stamping cylinder 101 is fixedly installed on the top of the support frame 1. The output end of the stamping cylinder 101 passes through the support frame 1 and is fixedly connected to a lifting plate 102. A stamping block group is provided below the lifting plate 102. A stamping groove 513 is provided on the top of the stamping seat 5. Both sides of the inner wall below the stamping groove 513 are provided with cavities 501 connected thereto. A forming module is installed on the inner wall of the cavity 501. A forming cavity is provided on the forming module. The forming cavity corresponds to and fits with the stamping block group. The stamping cylinder 101 pushes the lifting plate 102 to drive the stamping block group to descend, so as to stamp and form the profile on the stamping seat 5.

[0035] Four guide holes are provided at the four corners of the lifting plate 102, and the inner walls of the guide holes are slidably connected with guide frames 105, and the top of the guide frame 105 is fixedly connected to the top of the inner wall of the support frame 1;

[0036] An adjusting unit is provided between the lifting plate 102 and the punching block group. The punching block group is composed of a first punching block 103 and a second punching block 104. A through slot 204 is provided inside the first punching block 103. The inner wall of the through slot 204 is used to accommodate the second punching block 104. The first punching block 103 is driven to rise by controlling the adjusting unit on the lifting plate 102, thereby exposing the second punching block 104.

[0037] It should be noted that the adjustment unit includes: a hydraulic cylinder 201 fixedly mounted on the lifting plate 102, the output end of the hydraulic cylinder 201 passes through the lifting plate 102 and is fixedly connected to a lifting frame 202, the bottom end of the lifting frame 202 is fixedly connected to the top end of the first punching block 103; the top end of the second punching block 104 is fixedly connected to a connecting rod 203, the outer wall of the connecting rod 203 is slidably connected to the top end of the inner wall of the through groove 204 and the inner side of the top of the lifting frame 202, and the top end of the connecting rod 203 passes through the lifting frame 202 and is fixedly connected to the bottom end of the lifting plate 102;

[0038] When in use, the hydraulic cylinder 201 is controlled to contract to drive the lifting frame 202 to rise, and then the lifting frame 202 drives the first punching block 103 to rise, so that the second punching block 104 is exposed, and the conversion between the first punching block 103 and the second punching block 104 is realized;

[0039] The molding module includes a first molding module 502 and a second molding module 503, which correspond to the first punching block 103 and the second punching block 104 respectively. The first molding module 502 is provided with two groups, which are rotatably connected in the cavities 501 on both sides. The upper outer side of the first punching block 103 and the front ends of the punching seat 5 are fixedly connected with the second mounting seat 6. A tension spring 601 is installed between the two second mounting seats 6 adjacent to each other on the same side on the same plane. At this time, the molding cavity shape of the first molding module 502 is similar to an "M" shape, such as Figure 5 As shown, it is the first form of the first molding module 502. When the stamping unit drives the first stamping block 103 to descend, it will push the bottom ends of the molding cavities of the two first molding modules 502 to rotate inward with the rotation connection between the first molding module 502 and the inner wall of the cavity 501 as the center to perform molding. At this time, the molding cavity formed between the two first molding modules 502 is an isosceles trapezoid, which is the second form of the first molding module 502.

[0040] The first molding module 502 has an installation space 504 formed inside, and the second molding module 503 is installed in the installation space 504. A rotating shaft 508 is fixedly installed on the second molding module 503. The rotating shaft 508 is rotatably connected to the installation space 504 and is coaxial and cocentric with the first molding module 502. Both ends of the rotating shaft 508 pass through the first molding module 502 and are connected to conversion units.

[0041] The bottom end of the second molding module 503 and the inner wall of the installation space 504 are fixedly connected with the first mounting seat 505, and a tension spring 506 is arranged between the two first mounting seats 505, so that the second molding module 503 will not affect the operation of the first molding module 502 through the tension spring 506. Figure 7 As shown, an initial position limiting block 509 and a molding position limiting block 510 are installed on the inner wall of the installation space 504 to limit the position of the second molding module 503;

[0042] like Figure 7 As shown, the second molding module 503 is in the first state after being tightened by the tension spring 1 506 and restricted by the initial position limiting block 509; a pushing unit is provided on one side of the adjusting unit;

[0043] When the second forming module 503 is needed to cooperate with the second punching block 104 to form the profile, the second punching block 104 is converted by controlling the hydraulic cylinder 201 of the regulating unit, which will drive the pushing unit to descend. The second punching block 104 is driven down by the punching cylinder 101 of the punching unit, and the pushing unit is driven down at the same time. The pushing unit applies a thrust to the conversion unit, and the conversion unit drives the rotating shaft 1 508 to rotate inward, thereby driving the second forming module 503 to rotate inward, and the side wall of the second forming module 503 contacts the forming position limiting block 510, such as Fig. 9 As shown, this is the second form of the second forming module 503. As the punching cylinder 101 continues to extend, it drives the second punching block 104 to descend and push the second forming module 503 and the first forming module 502 to rotate inward to shape the profile. Fig.10 As shown, this is the third state of the second molding module 503;

[0044] The pushing unit and the conversion unit mentioned above are combined into an adjustment component, and the adjustment component also includes a linkage component;

[0045] The pushing unit includes: a fixed frame 401 fixedly installed on both sides of the lifting plate 102, the inner wall of the fixed frame 401 is slidably connected with an adjusting frame 402, and a guiding mechanism is provided between the two sides of the adjusting frame 402 and the inner wall of the fixed frame 401; and a horizontal plate 405 fixedly installed on both sides of the bottom end of the adjusting frame 402, the horizontal plate 405 is slidably connected with a T-shaped slide bar 406, the bottom end of the T-shaped slide bar 406 is fixedly connected with a pressure plate 407, the outer wall of the T-shaped slide bar 406 is slidably connected with a thrust spring three 408, and the two ends of the thrust spring three 408 are respectively fixedly connected to the top of the pressure plate 407 and the bottom end of the adjusting frame 402.

[0046] The linkage component is installed between the inner side of the adjustment frame 402 and the lifting frame 202 to drive the adjustment frame 402 to move along the inner wall of the fixed frame 401;

[0047] When the above device is in use, when the hydraulic cylinder 201 of the adjustment unit drives the first punching block 103 to rise through the lifting frame 202, the adjustment frame 402 is driven to descend through the linkage component, and the adjustment frame 402 will drive the pressing plate 407 to descend. After the conversion between the first punching block 103 and the second punching block 104 is completed, the pressing plate 407 is located below the second punching block 104. When the hydraulic cylinder 201 drives the pressing plate 407 to descend, it will also drive the second punching block 104 to descend. By utilizing the height difference between the second punching block 104 and the pressing plate 407, the pressing plate 407 will first contact with the conversion unit, drive the rotating shaft 1 508 to rotate inwardly, thereby driving the second molding module 503 to rotate inwardly, and the side wall of the second molding module 503 contacts with the molding position limiting block 510 to form the second form of the second molding module 503, thereby realizing the conversion between the first molding module 502 and the second molding module 503;

[0048] The conversion unit mentioned above includes: an L-shaped connecting rod 409 fixedly connected to the rotating shaft 1 508, and the outer wall of the outer handle of the L-shaped connecting rod 409 is rotatably connected with a rolling sleeve 410. When the pressing plate 407 is pressed down, the outer wall of the rolling sleeve 410 contacts the bottom surface of the pressing plate 407, pushing the L-shaped connecting rod 409 to rotate, thereby driving the rotating shaft 1 508 to rotate;

[0049] It should be noted that the linkage components include: vertical tooth plates installed on both sides of the top of the inner wall of the lifting frame 202, the vertical tooth plates include vertical plates 302, and the outer wall of the vertical plates 302 is vertically arrayed with teeth 1 303; U-shaped mounting frames 305 installed on both ends of the inner side of the fixed frame 401, and the inner side of the U-shaped mounting frame 305 is rotatably connected with a driven gear 306; and teeth 2 304 vertically arrayed on the inner side of the adjustment frame 402, and the teeth 2 304 and the teeth 1 303 on the vertical tooth plate are respectively meshed with the two sides of the driven gear 306;

[0050] When the hydraulic cylinder 201 drives the first punching block 103 to rise through the lifting frame 202, the vertical plate 302 will be driven to rise at the same time. The vertical plate 302 will drive the driven gear 306 to rotate through the meshing between the first tooth 303 and the driven gear 306. The driven gear 306 pushes the adjusting frame 402 downward through the meshing between the second tooth 304 vertically distributed on the inner side of the adjusting frame 402, thereby driving the pressing plate 407 to descend.

[0051] The guiding mechanism mentioned above includes: vertical guide grooves 403 opened on both sides of the inner wall of the fixed frame 401, and guide blocks 404 fixedly installed on both sides of the adjustment frame 402. The outer wall of the guide block 404 is slidably connected to the inner wall of the vertical guide groove 403 to guide and limit the adjustment frame 402 in the up and down moving state.

[0052] Example 2: Reference Figure 1-Figure 10Based on the first embodiment, a municipal sign profile non-cutting forming device is provided, wherein a fixing rod 511 is installed on the inner upper side of the second forming module 503, and a roller 512 is fixedly connected to the bottom end of the fixing rod 511. Figure 5 , Figure 6 , Figure 7 In the first form shown, the roller 512 cooperates with the first forming module 502. When the punching unit drives the first punching block 103 to punch, when the first forming module 502 rotates inward, the roller 512 also rotates inward.

[0053] Compared with the existing device, without changing the device, the profile can be stamped into another shape by changing the form, so as to cope with stamping needs of different types and expand the scope of use; in the first form, the roller 512 rounds the corners of the stamped profile to avoid material breakage caused by hard chamfering. At the same time, the roller 512 is protruding and will squeeze the corners, so that the stamped profile is tightened. When installed on the trapezoidal rod, there is an interference fit and it will not slide at will.

[0054] Example 3: Reference Figure 1-Figure 10 On the basis of the second embodiment, a municipal identification profile non-cutting forming construction device is provided, and locking structures are installed on both sides of the opposite ends of the two first forming modules 502, and the locking structures include: a mounting groove 702, and the opposite sides of the two mounting grooves 702 are provided with a slide groove 703, and the inner wall of the slide groove 703 is slidably connected with a locking protrusion 701, and the inner side of the locking protrusion 701 is fixedly connected with a thrust spring 1 704, and the thrust spring 1 704 is fixedly connected with a T-shaped connecting rod 705 on the side away from the locking protrusion 701, and the inner wall of the mounting groove 702 is provided with a through hole 711 on the same plane as the side away from the slide groove 703, and the inner wall of the through hole 711 is slidably connected with the outer wall of the T-shaped connecting rod 705, and the outer wall of the T-shaped connecting rod 705 is provided with a thrust spring 2 706, and the two ends of the thrust spring 2 706 are respectively fixedly connected with the outer side of the through hole 711 and the inner side of the T-shaped connecting rod 705;

[0055] The bottom end of the T-shaped connecting rod 705 is fixedly connected with a transverse toothed plate 707, and a gear 2 is arranged below the transverse toothed plate 707. The gear 2 includes a circular plate 708 and three teeth 709 distributed around it, and the three teeth 709 are meshed with the teeth on the transverse toothed plate 707. The center of the circular plate 708 is fixedly connected with a rotating shaft 3 710, and the outer wall of the rotating shaft 3 710 is rotatably connected to the inside of the first molding module 502, and extends out of the first molding module 502 and is fixedly connected with a gear 3 712;

[0056] When the second molding module 503 is Fig. 9In the second form shown, when the second molding module 503 rotates to the second form, the fixing rod 511 drives the roller 512 to rotate, and the roller 512 squeezes the locking protrusion 701. The upper end surface of the locking protrusion 701 is set to an arc shape, and when squeezed from above, it shrinks into the slide groove 703. When the squeezing ends, it is affected by the thrust spring 1 704 to reset outward, and cooperates with the molding position limiting block 510 to limit and fix the roller 512, thereby improving the stability of the structure of the second molding module 503 in the second form.

[0057] When it needs to be released, manually turn gear three 712 or hold the rack and drag it, and drive the circular plate 708 to rotate through the rotating shaft three 710. The circular plate 708 drives the horizontal tooth plate 707 to move outward through the meshing teeth three 709 distributed on its outer side, drives the thrust spring two 706 to be squeezed, and at the same time drives the locking protrusion 701 to shrink into the slide groove 703, thereby releasing the restriction on the roller 512, thereby driving the second molding module 503 to reset to the first form.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
