Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to an automatic device for cold processing of metal wires. Background Art

[0002] Titanium flat bar is a flat material made of titanium or titanium alloys. It has excellent corrosion resistance, high strength, low density, and good biocompatibility. Furthermore, titanium flat bar has high tensile strength and yield strength, and can withstand large loads, making it widely used in various fields.

[0003] At present, the common method of forming titanium flat bars is rolling, which uses a rolling mill to continuously or intermittently roll the titanium material to form a flat shape. The specific process is: 1. Prepare the titanium billet, which is usually a preliminary shape obtained by smelting, casting or forging. 2. Feed the titanium billet into the rolling mill, and through the rolling action of the rollers, it is gradually thinned and widened to form a titanium flat bar. 3. As needed, multiple rolling processes may be required to achieve the required size and precision. 4. During the rolling process, parameters such as the gap between the rollers, rolling speed, and rolling force can be adjusted to control the thickness, width, and surface quality of the titanium flat bar.

[0004] Roll forming, a commonly used method in metal processing, has advantages such as high production efficiency, but it also has some disadvantages, especially when rolling difficult-to-process materials such as titanium flat bar. For example, the rolling process requires high surface quality of the raw material, otherwise the rolled titanium flat bar may have shape defects such as bending and twisting, resulting in low forming precision and high development difficulty. To this end, we have proposed an automated device for cold working of metal wire to effectively address these drawbacks. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1 to 9 An automated cold processing device for metal wire comprises an automatic wire take-up machine 1, a frame 2, and a pay-off machine 3, spaced horizontally apart. The wire to be processed is coiled onto the pay-off roller of the pay-off machine 3. The end of the wire passes through the top of the frame 2 and is secured to the take-up roller of the automatic wire take-up machine 1. When the automatic wire take-up machine 1 is in operation, the take-up roller is rotated by a driving source, thereby winding the wire. A straightening mechanism 4, an automatic rolling and forming mechanism 5, and a main traction machine 6 are sequentially arranged on the frame 2 along the direction in which the wire is pulled. In this embodiment, the main traction machine 6 primarily comprises two traction wheels and a power source for driving the traction wheels. The wire passes between the two traction wheels in an S-shape. When the power source drives the traction wheels to rotate, the wire is pulled. During the pulling process, the wire first passes through the straightening mechanism 4 to correct its flatness and straightness, and then passes through the automatic rolling and forming mechanism 5 to roll the wire.

[0031] The straightening mechanism 4 includes a mounting base 401 fixed to the top of the frame 2. A horizontally arranged mounting plate 402 is fixedly connected to the top of the mounting base 401. A plurality of movable straightening guide wheels 403 and fixed straightening guide wheels 404 are distributed above and below the front of the mounting plate 402. An annular limiting groove 405 is provided on the wheel surface of each movable straightening guide wheel 403 and each fixed straightening guide wheel 404 to prevent the metal wire from moving axially along the straightening guide wheel. The movable straightening guide wheels 403 are arranged at intervals in the horizontal direction. A height adjustment assembly 406 for adjusting the height of the movable straightening guide wheels 403 is provided on the mounting plate 402. This allows the distance between the movable straightening guide wheels 403 and the fixed straightening guide wheels 404 to be adjusted to accommodate metal wires of different sizes. Specifically, the height adjustment assembly 406 includes a chute 4061 vertically defined on the mounting plate 402. A slider 4062 is slidably connected within the chute 4061. The slider 4062 forms an I-shaped projection on a horizontal plane, allowing it to move only up and down along the chute 4061, and not forward or backward. The movable straightening guide wheel 403 is rotatably connected to the front of the slider 4062. An adjustment bolt 4063 is rotatably connected to the top of the slider 4062, and an adjustment nut 4064 is fixed to the top of the mounting plate 402. The adjustment bolt 4063 is vertically disposed and threadedly engaged with the adjustment nut 4064. To adjust the height of the movable straightening guide wheel 403, rotating the adjustment bolt 4063 drives the slider 4062 downward or upward along the chute 4061, thereby adjusting the height of the movable straightening guide wheel 403 to accommodate metal wires of varying sizes. In addition, each fixed straightening guide wheel 404 is arranged at intervals in the horizontal direction and is rotatably connected to the mounting plate 402. The fixed straightening guide wheel 404 and the movable straightening guide wheel 403 are staggered with each other. The metal wire passes between the fixed straightening guide wheel 404 and the movable straightening guide wheel 403 along the pulling direction, thereby correcting the flatness and straightness of the metal wire.

[0032] Furthermore, the mounting base 401 is vertically penetrated by a strip-shaped hole 407 located between the mounting plate 402 and the pay-off machine 3. Two locking screws 408 are movably provided in the vertical direction and are arranged front and back. An auxiliary guide roller 409 is rotatably connected to the upper end of each locking screw 408. Before being straightened, the metal wire first passes between the two auxiliary guide rollers 409, preventing it from being easily displaced back and forth. The wire is then straightened by the movable straightening guide wheel 403 and the fixed straightening guide wheel 404, which are arranged vertically and horizontally, to ensure the straightening effect. Locking nuts 4010 located on the upper and lower sides of the strip-shaped hole 407 are threadedly connected to the locking screw 408. Each locking nut 4010 is tightly fitted with the mounting base 401 to secure the locking screw 408 to the mounting base 401. When the locking nut 4010 is loosened, the locking screw 408 can be moved in the strip hole 407, thereby adjusting the distance between the two auxiliary guide rollers 409 to accommodate metal wires of different sizes.

[0033] Secondly, the automatic rolling and forming mechanism 5 includes a mounting housing 501 fixed to the frame 2. A wire threading hole 502 is horizontally traversed through the center of the mounting housing 501 for passing the metal wire. Four rolling wheels 503 are circumferentially and evenly spaced around the threading hole 502. The gaps between the four rolling wheels 503 form a wire forming gap 504, enabling the metal wire to be rolled and formed. A spacing adjustment assembly 505 is provided on the mounting housing 501 for adjusting the distance between the rolling wheels 503, enabling the production of flat strips of varying sizes as required.

[0034] Furthermore, the mounting housing 501 has a disc-shaped outer profile and is composed of two removable shells, one of which is fixedly connected to the frame 2. When the components within the mounting housing 501 need to be assembled, repaired, or replaced, the other shell is removed to expose the components within the mounting housing 501, facilitating various operations. The cavity of the mounting housing 501 has a cross-shaped structure, which facilitates the sliding of other components within. The threading hole 502 is located at the center of the cross-shaped structure, and grooves 506 are provided on the outside of the mounting housing 501, corresponding one-to-one with the ends of the cross-shaped structure.

[0035] Furthermore, the spacing adjustment assembly 505 includes a knob 5051 screwed into a groove 506. An adjustment screw 5052 is fixedly connected to the knob 5051. The end of the adjustment screw 5052 is threadedly connected to a wheel frame 5053 that slides within the cross-shaped structure. The rolling wheel 503 is rotatably connected to the wheel frame 5053. Normally, the knob 5051 is fixed into the groove 506, thereby ensuring that the rolling wheel 503 does not move within the cross-shaped structure, thereby ensuring the required dimensional accuracy of the titanium flat bar. When adjustment is required, the screw on the knob 5051 is first unscrewed. Then, the knob 5051 is rotated using a wrench compatible with the knob 5051, which in turn rotates the adjustment screw 5052. The inner cavity of the mounting shell 501 adopts a special cross-shaped structure design, so that the wheel frame 5053 can only move in one direction. When the adjusting screw 5052 rotates, since the wheel frame 5053 is threadedly connected to the adjusting screw 5052, the wheel frame 5053 can be driven to slide along one of the channels in the cross-shaped structure, thereby adjusting the rolling wheel 503 to meet the requirements of different sizes.

[0036] In this embodiment, it should be noted that the automatic wire take-up machine 1, wire pay-off machine 3 and main traction machine 6 used in this application are all existing technologies, so their specific structures and principles are not described here in detail.

[0037] When titanium flat bars need to be processed, the metal wire coil to be processed is placed on the pay-off roller of the pay-off machine 3. The end of the metal wire passes in sequence between the two auxiliary guide rollers 409, between the movable straightening guide wheel 403 and the fixed straightening guide wheel 404, and through the metal wire forming gap 504. It then passes between the two traction wheels on the main traction machine 6 and is finally fixed to the take-up roller of the automatic take-up machine 1. When the automatic take-up machine 1 and the main traction machine 6 are in operation, the metal wire can be pulled, and the flatness and straightness of the metal wire are first corrected by the straightening guide wheel. The metal wire is then rolled into shape through the metal wire forming gap 504. Finally, the wire is taken up by the automatic take-up machine 1, completing the automatic forming and rolling of the titanium flat bars.
