Description

Technical Field

[0001] This utility model relates to the field of hardware product processing technology, and in particular to a device for turning, curling, extruding and thickening the opening of hardware products. Background Technology

[0002] The edge-turning, curling, and extrusion thickening process for metal products is a comprehensive technique primarily used to achieve the following functions: preventing product deformation and cracking, eliminating burrs and sharp edges, improving sealing performance, and meeting precision assembly requirements. This combination of processes significantly enhances the durability and functionality of the product.

[0003] Currently, most manufacturers use direct-drive spinning machines with turning functions to process the rims of metal basins. To improve machining accuracy, a positioning mold that matches the metal basin is typically used to hold the workpiece in place. However, when machining metal basins of various sizes, manufacturers must pre-order molds of different sizes and frequently load and unload them according to processing requirements. This operation not only reduces processing efficiency but also increases production costs. Utility Model Content

[0004] Therefore, it is necessary to provide a machine for turning, curling, extruding and thickening the opening of metal products to address the problems of low efficiency and high cost of mold adaptation at the opening of metal basins.

[0005] An apparatus for turning, curling, extruding, and thickening the edge of hardware products, comprising: The frame has two three-dimensional guide rails, an upper mold and a servo motor fixedly connected to its top. One of the three-dimensional guide rails has a shearing blade and a flattening wheel fixedly connected to its driving part, and the other three-dimensional guide rail has a rounded wheel fixedly connected to its driving part. An adjustable positioning mold includes a mounting frame fixedly connected to the end of the output shaft of a servo motor. Slide cavities are provided on both sides of the mounting frame. An adjusting rod is rotatably connected inside the mounting frame. A driving bevel gear is fixedly connected to the surface of the adjusting rod. Two driven bevel gears are meshed with the surface of the driving bevel gear. A threaded post rotatably connected to one end of each driven bevel gear is fixedly connected to the mounting frame. One end of the threaded post extends into the interior of the slide cavity. An extension block slidably connected to the slide cavity is threadedly connected to the surface of the slide cavity.

[0006] In one embodiment, the vertical cross-sectional shapes of the sliding cavity and the extension block are both matching convex shapes.

[0007] In one embodiment, an auxiliary adjusting block is fixedly connected to the top of the adjusting rod, and the horizontal cross-sectional shape of the top of the auxiliary adjusting block is a regular hexagon.

[0008] In one embodiment, the top of the mounting frame has a countersunk hole, and the auxiliary adjustment block is disposed inside the countersunk hole.

[0009] In one embodiment, the top of the extension block has a mounting cavity, a friction block is slidably connected inside the mounting cavity, and a spring is provided between the friction block and the mounting cavity.

[0010] In one embodiment, the vertical cross-sectional shape of the mounting cavity and the friction block is n-shaped.

[0011] In one embodiment, both ends of the bottom of the friction block are provided with friction-enhancing blocks that contact the sliding cavity, and the friction-enhancing blocks are made of fluororubber material.

[0012] In one embodiment, the inner top wall of the friction block has a reserved cavity, and the top of the spring extends into the interior of the reserved cavity.

[0013] Beneficial effects The above-mentioned equipment for turning, curling, extruding and thickening the opening of hardware products drives the active bevel gear and the driven bevel gear to move horizontally by adjusting the rod, thereby enabling stepless adjustment of the mold width. It can adapt to the processing needs of metal basins with different inner diameters, significantly reduce mold change time and ensure processing concentricity. When the metal basin is pressed down, the friction block compresses the fluororubber friction block, causing it to fill the gap between the mounting cavity and the sliding cavity, forming a self-locking effect. This effectively suppresses vibration displacement during turning / curling and improves machining stability. Attached Figure Description

[0022] The following is combined with Figures 1-4 This invention describes a device for turning, curling, extruding, and thickening the opening of hardware products.

[0023] In one embodiment, a device for turning, curling, extruding, and thickening the edge of hardware products includes: a frame 100 and an adjustable positioning mold 800. The top of the frame 100 is fixedly connected to two three-dimensional guide rails 200, an upper mold 300, and a servo motor 400. The three-dimensional guide rails 200 include horizontal electric guide rails, and the driving part of the horizontal electric guide rails is fixedly connected to vertical electric guide rails. One of the vertical electric guide rails is fixedly connected to a shearing blade 500 and a flattening wheel 600, and the driving part of the other vertical electric guide rail is fixedly connected to a rounding wheel 700. The upper mold 300 includes a suspended mounting frame, and the top of the suspended mounting frame is fixedly connected to an electric cylinder located directly above the output shaft of the servo motor 400. The end of the output shaft of the electric cylinder is rotatably connected to a pressure block. When a user needs to process a metal basin, first, the metal basin is placed upside down on top of the adjustable positioning mold 800. The electric cylinder is manually controlled to drive the pressure block, firmly pressing the metal basin against the adjustable positioning mold 800. Then, the servo motor 400 is manually controlled to drive the metal basin to rotate at a constant speed through the adjustable positioning mold 800. Subsequently, one of the horizontal electric guide rails drives the connected vertical electric guide rail, along with the edge trimming blade 500, to cut away the uneven edges of the metal basin's rim. After completion, the horizontal electric guide rail drives the vertical electric guide rail, along with the edge trimming blade 500, away from the metal basin. Then, another horizontal electric guide rail... The vertical electric guide rail connected to the horizontal electric guide rail, along with the rounded edge wheel 700, rounds the corners of the metal basin opening. After completion, the horizontal electric guide rail moves the vertical electric guide rail and the rounded edge wheel 700 away from the metal basin. Then, one of the vertical electric guide rails lowers the flattening wheel 600 to the same height as the rounded edge of the metal basin. The horizontal electric guide rail then moves the connected vertical electric guide rail and the flattening wheel 600 to flatten the rounded edge of the metal basin opening. Finally, the horizontal electric guide rail moves the vertical electric guide rail and the flattening wheel 600 back to their original positions, and at the same time, the electric cylinder moves the pressure block back to its original position. At this point, the worker can remove the processed metal basin without any obstruction.

[0024] like Figure 2 , Figure 3 and Figure 4As shown, the adjustable positioning mold 800 includes a mounting frame 810 fixedly connected to the end of the output shaft of the servo motor 400. Slide cavities 811 are provided on both sides of the mounting frame 810. An adjusting rod 820 is rotatably connected inside the mounting frame 810. A driving bevel gear 830 is fixedly connected to the surface of the adjusting rod 820. Two driven bevel gears 840 are meshed with the surface of the driving bevel gear 830. One end of each driven bevel gear 840 is fixedly connected to a threaded post 850 rotatably connected to the mounting frame 810. The two driven bevel gears 840 are symmetrically distributed on both sides of the driving bevel gear 830. The threads of the two threaded posts 850 are in the same direction. One end of each threaded post 850 penetrates into the interior of the slide cavity 811. An extension block 860 is threadedly connected to the slide cavity 811. When the driving bevel gear 830 rotates, it simultaneously drives two driven bevel gears 840 to rotate in opposite directions. Since the thread directions on the surfaces of the two threaded columns 850 are the same, the two threaded columns 850 in opposite rotation states can drive the extension block 860 connected to them to move relative to or away from each other. The vertical cross-sectional shapes of the slide cavity 811 and the extension block 860 are both matching convex shapes. An auxiliary adjusting block 870 is fixedly connected to the top of the adjusting rod 820. The horizontal cross-sectional shape of the top of the auxiliary adjusting block 870 is a regular hexagon. A countersunk hole 812 is opened on the top of the mounting frame 810, and the auxiliary adjusting block 870 is set inside the countersunk hole 812.

[0025] like Figure 2 , Figure 3 and Figure 4 As shown, the top of the extension block 860 is provided with a mounting cavity 861, and a friction block 880 is slidably connected inside the mounting cavity 861. A spring 890 is provided between the friction block 880 and the mounting cavity 861. The vertical cross-sectional shape of the mounting cavity 861 and the friction block 880 is n-shaped. Both ends of the bottom of the friction block 880 are provided with a resistance-increasing block 8100 that contacts the sliding cavity 811. The resistance-increasing block 8100 is a fluororubber material component. A reserved cavity 881 is provided in the inner top wall of the friction block 880, and the top of the spring 890 penetrates into the interior of the reserved cavity 881.

[0026] In this embodiment, when the electric cylinder drives the pressure block to press the metal basin against the top of the mounting frame 810, the metal basin presses down on the friction block 880. The friction block 880 squeezes the friction-increasing block 8100, which is made of fluororubber, so that the friction-increasing block 8100 is compressed in the gap between the mounting cavity 861, the friction block 880 and the sliding cavity 811, and the extension block 860 is firmly locked in the sliding cavity 811, which further improves the stability of the metal basin processing.

[0027] Working principle: When the operator needs to process metal basins of different sizes, simply rotate the adjusting rod 820 to drive the driving bevel gear 830 to rotate. The driving bevel gear 830 simultaneously drives the two driven bevel gears 840 to rotate synchronously, and through the threaded column 850, drives the extension block 860 to move horizontally along the sliding cavity 811 until the overall horizontal length of the two extension blocks 860 matches the inner diameter of the metal basin. At this point, the metal basin is centered and inverted on top of the adjustable positioning mold 800, which can accommodate processing of different sizes and reduce positional deviations during turning / flanging / extrusion, significantly improving processing accuracy.

[0028] It should be noted that the horizontal electric guide rail, vertical electric guide rail, electric cylinder, and servo motor 400 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the horizontal electric guide rail, vertical electric guide rail, electric cylinder, and servo motor 400 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
