[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. The described embodiments are some of the embodiments of the present application, but not all the embodiments of the present application.

[0021] Embodiment 1

[0022] With reference to Figures 1-5 , in order to realize the precise positioning, automatic twisting, fixed-length shearing and slot pressing of the steel wire 102 in the umbrella framework 100, the slot pressing refers to pressing the twisted steel wire 102 into the steel wire slot 103 after twisting the steel wire 102 into a twisted shape, thereby completing the assembly between the steel wire 102 and the umbrella framework 103. The present embodiment provides a steel wire twisting-shearing-slot pressing device for an umbrella framework, which comprises the umbrella framework 100 to be processed, a positioning mechanism 200, a torsion-pressing mechanism 300 and a shearing mechanism 400. The positioning mechanism 200 is used for positioning the umbrella framework 100, the torsion-pressing mechanism 300 is used for twisting and pressing the steel wire 102, and the shearing mechanism 400 is used for shearing the twisted steel wire 102. Similarly, the shearing mechanism 400 can also be used for shearing the twisted steel wire 102 through position adjustment. In the present embodiment, the torsion-pressing mechanism 300 is used for pressing.

[0023] More specifically, with reference again to Figure 2 , the umbrella framework 100 comprises a framework end portion 101, a steel wire 102 arranged on the framework end portion 101 and a steel wire slot 103. In umbrella manufacturing, the steel wire 102 needs to be sleeved on the framework end portion 101 to fix the umbrella framework, so the steel wire 102 needs to be twisted into a twisted shape before being embedded in the framework end portion 101. Then, the excess part of the twisted steel wire 102 is sheared according to the length of the steel wire slot 103, and the twisted steel wire 102 is pressed into the steel wire slot 103 to complete the assembly.

[0024] Further, the positioning mechanism 200 in the embodiment includes a clamping block 201, a positioning column 202, a lifting plate 203 and a lifting assembly 204. The clamping block 201 can clamp the skeleton end 101 by forming a clamping space through opening and closing, and the positioning column 202 is embedded with the skeleton end 101 for positioning the skeleton end 101 in the clamping space. The positioning column 202 is arranged on the side of the lifting plate 203, and the lifting assembly 204 is used to drive the lifting plate 203 to move up and down.

[0025] The basic process realized by the positioning mechanism 200 is as follows: two clamping blocks 201 in the shape of semicircular arcs and hinged at the bottom are opened and closed under the action of a cylinder. After the clamping blocks 201 are opened, the skeleton end 101 is embedded in the positioning column 202 for positioning. The clamping blocks 201 are closed to clamp and fix the skeleton end 101. Meanwhile, the lifting plate 203 and the lifting assembly 204 can adaptively adjust the height of the positioning column 202. After the steel wire 102 is pressed into the steel wire groove 103, the umbrella skeleton 100 is taken out by lifting to a suitable height. In addition, the height adjustment is also convenient for embedding the skeleton end 101 in the positioning column 202 at the beginning of assembly.

[0026] Further, referring again to the schematic view of Figure 3 , the torsion pressing mechanism 300 in the embodiment includes a mechanical clamp 301, a rotating arm 302, a connecting block 303, a rotating motor 304, a sliding assembly 305, a support frame 306 and a support rod 307.

[0027] Specifically, the mechanical clamp 301 is used to twist and twist the steel wire 102 leaked from the umbrella skeleton 100, and press the cut steel wire 102 into the steel wire groove 103. The mechanical clamp 301 is arranged below the rotating arm 302. The rotating motor 304 can drive the rotation of the rotating arm 302. The sliding assembly 305 is connected with the rotating arm 302 through the connecting block 303, and is used to drive the rotating arm 302 to slide up and down.

[0028] In order to realize the downward slotting operation of the sliding assembly 305 driving the rotating arm 302 in the embodiment, the sliding assembly 305 further includes a lead screw sliding block 305a, a lead screw motor 305b, a track block 305c and a sliding rail 305d. The lead screw sliding block 305a and the lead screw motor 305b are in screw sliding fit. One side of the lead screw sliding block 305a is connected with the connecting block 303, and the other side is connected with the track block 305c. The track block 305c is limited to slide up and down on the sliding rail 305d. The support rod 307 is used to fixedly support the support frame 306, and the sliding assembly 305 is fixed through the support frame 306.

[0029] The basic process of the torsion and pressure mechanism 300 in this embodiment is as follows: the rotating arm 302 is above the steel wire 102 and the steel wire groove 103 at the end of the framework 101, the mechanical clamp 301 clamps the steel wire 102, and then the rotating arm 302 drives the mechanical clamp 301 to rotate, so as to twist the steel wire 102 into a twisted shape, and the height difference between the upper and lower parts is realized by the sliding assembly 305.

[0030] It should be noted that the screw rod and the sliding block 305a and the screw motor 305b are matched, which means that the rotation is converted into linear motion through the thread engagement between the screw rod (screw) and the nut, which is a mature technology and will not be described in detail here.

[0031] Further, referring again to the schematic of Figures 4-5 , the shearing mechanism 400 of this embodiment includes a mechanical shear 401, a driving component 402, a transverse assembly 403, and a longitudinal assembly 404.

[0032] Specifically, the mechanical shear 401 is used to shear the twisted steel wire 102 after the torsion and pressure mechanism 300 into a length suitable for the steel wire groove 103. The driving component 402 is used to drive the shearing of the mechanical shear 401, the longitudinal assembly 404 is connected with the driving component 402 and is used to drive the longitudinal movement of the mechanical shear 401, and the transverse assembly 403 is connected with the longitudinal assembly 404 and is used to drive the transverse movement of the longitudinal assembly 404. The driving component 402 of this embodiment is an electric motor that drives the mechanical shear 401, and similarly, it can also be a hydraulic shear or a pneumatic shear, and this embodiment adopts an electric motor.

[0033] The longitudinal assembly 404 includes a longitudinal connecting block 404a, a longitudinal screw rod 404b, and a support plate 404c.

[0034] The driving component 402 is connected with the longitudinal screw rod 404b through the longitudinal connecting block 404a, the longitudinal screw rod 404b drives the longitudinal movement of the longitudinal connecting block 404a, and the support plate 404c is used to support the longitudinal connecting block 404a and the longitudinal screw rod 404b.

[0035] The transverse assembly 403 includes a transverse sliding block 403a and a transverse screw rod 403b; the transverse sliding block 403a is connected with the support plate 404c, and the transverse screw rod 403b is used to drive the transverse movement of the transverse sliding block 403a.

[0036] In order to realize the angle adjustment of the mechanical shear 401, an arc-shaped slot 404a-1 is arranged on the longitudinal connecting block 404a, the driving component 402 is connected with the longitudinal connecting block 404a through an angle block 404a-2, and the angle block 404a-2 drives the angle adjustment of the driving component 402 through the sliding within the arc-shaped slot 404a-1. In the embodiment, the angle block 404a-2 slides along the arc-shaped slot 404a-1 to adjust the included angle (0°-30°) between the mechanical shear 401 and the steel wire, so as to avoid the stress concentration of the shear stress, and meanwhile, the different diameter positioning columns 202 and clamping blocks 201 can be replaced to adapt to the processing requirements of different steel wires 102.

[0037] The steel wire torsion shear groove equipment of the umbrella framework in the embodiment further comprises a control panel 500 and a workbench 600; the workbench 600 is used for the installation and support of the umbrella framework 100, the positioning mechanism 200, the torsion mechanism 300, the shear mechanism 400 and the control panel 500. It should be noted that the control panel 500 is used for controlling the rotation of the motor and belongs to the part of automatic control. The equipment can freely adjust the torsion steel wire turns and the shear depth through the touch screen on the control panel 500, and can freely adjust the speed. It can be understood that the embodiment should also include an electrical control system and the layout of the electrical circuit, etc. The electrical control system is composed of an electrical safety protection system, a power supply, an alarm system, a programmable controller, a touch screen and an operation button. The automatic control principle part and the layout of the electrical control system and circuit involved all belong to the very mature technology, and the ordinary skilled in the art can realize them by referring to the existing technology. The position structure layout of each electrical component, the automatic control principle part and the electrical control system belong to the unnecessary technology, and therefore are not described in detail.

[0038] The operation flow of the equipment is as follows:

[0039] The positioning stage: the framework end part 101 is embedded into the positioning column 202, the clamping block 201 is closed to form a clamping space, and the lifting assembly 204 adjusts the lifting plate 203 to the preset height.

[0040] The twisting stage: the rotating motor 304 drives the rotation of the rotating arm 302, and the mechanical clamp 301 clamps the steel wire 102 to complete the twisting;

[0041] The shear stage: the horizontal screw rod 403b drives the horizontal movement of the mechanical shear 401 above the steel wire 102, the longitudinal screw rod 404b adjusts the shear height, the driving component 402 triggers the shear action, and the excess steel wire 102 is sheared off;

[0042] The groove pressing stage: the sliding assembly 305 presses down the rotating arm 302 to press the twisted steel wire 102 into the steel wire groove 103.

[0043] Through the above process, it is ensured that the skeleton end 101 is fixed to a fixed position accurately, the transverse, longitudinal and angle adjusting assemblies realize self-adaptation of the shearing length, and through the cooperation of the mechanical clamp 301 and the mechanical shear 401, the mechanical shear 401 is used to shear to the adaptive length after the mechanical clamp 301 is used to twist the steel wire 102, and the twisted steel wire 102 is pressed into a groove through the mechanical clamp 301 or the mechanical shear 401, so that the assembly of the steel wire 102 on the umbrella skeleton 100 is completed.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the protection scope of the present application. For those skilled in the art, on the basis of the above description and ideas, other different forms of changes or variations can also be made, and here it is not necessary and impossible to exhaust all the embodiments.
