Description
Technical Field
[0001] The invention belongs to the technical field of PtRh3 catalytic mesh preparation, and specifically relates to a platinum mesh alloy stretching device. Background Art
[0002] In recent years, the price of precious metal rhodium has risen sharply, and the content of precious metal rhodium has become an important factor affecting the price of binary platinum mesh. Due to the small difference between the atomic radius of Rh and platinum, its effect of solid solution strengthening platinum at room temperature is not very strong, but its oxidation volatilization weight loss is less than platinum below 1000℃, and its melting point and high-temperature strength are higher than platinum. It is the most stable high-temperature solid solution strengthening element for platinum. The addition of rhodium to platinum improves the high-temperature endurance strength of platinum alloys and reduces platinum consumption. In order to reduce the cost of binary platinum mesh, a new platinum mesh product (new binary PtRh3) is developed by changing the metal ratio and processing technology of the platinum mesh, so that the new binary PtRh3 can achieve the same strength and elongation as PtRh5, which can reduce capital costs and increase market share.
[0003] The preparation process of binary PtRh3 catalytic mesh mainly consists of the steps of raw material preparation, alloy preparation, catalytic mesh forming, surface treatment, product packaging and quality inspection. The catalytic mesh forming requires the prepared PtRh3 alloy to be processed into a catalytic mesh with a specific shape and structure by stretching, rolling, weaving or electrochemical deposition. In the process of stretching the PtRh3 alloy, the internal structure and performance of the alloy will change due to factors such as improper stretching speed, influence of molds and processing equipment, improper temperature control, and complex shape and size of the stretched parts, resulting in an uneven surface of the alloy and stress concentration unit problems when the alloy is subjected to stress, thereby increasing the difficulty of subsequent processing and reducing the service life of the product.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. The technical solutions of the present invention are described in detail below in conjunction with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.
[0018] See also Figures 1 to 6 This embodiment proposes a platinum mesh alloy stretching device, including: a stretching die 1, a clamping device 2 and a pushing device 3; a first track 4 is fixedly connected to the lower side of the entrance of the stretching die 1, and a pushing device 3 is slidably connected to the first track 4, and the PtRh3 alloy is pushed into the interior of the stretching die 1 through the pushing device 3; two symmetrical second tracks 5 are fixedly connected to the lower side of the wire outlet of the stretching die 1, and a hollow structure is formed between the two second tracks 5; a clamping device 2 is slidably connected to the second track 5, and the PtRh3 alloy wire is pulled out through the clamping device 2. The stretching die 1, the clamping device 2 and the pushing device 3 are all existing structures.
[0019] A symmetrical trigger device 7 is fixedly connected to the upper and lower wire outlet of the stretching die 1, a reset spring 18 is fixedly connected to the bottom of the symmetrical trigger device 7, the other end of the reset spring 18 is fixedly connected to a moving column 17, the top of the moving column 17 is fixedly connected to a ejector pin 12, the ejector pin 12 is slidably connected to the trigger device 7, the needle tips of the upper and lower ejector pins 12 point to the wire outlet of the stretching die 1, and the distance between the needle tips of the upper and lower ejector pins 12 is adapted to the qualified PtRh3 alloy wire, so that the qualified PtRh3 alloy wire can pass normally without touching the upper and lower ejector pins 12.
[0020] A fixed plate 14 is fixedly connected to the side wall of the symmetrical trigger device 7, a button 15 is fixedly connected to the fixed plate 14, and the button 15 is electrically connected to the cylinder 19; a slide groove 16 is provided on the side wall of the symmetrical trigger device 7, a movable plate 13 is slidably connected inside the slide groove 16, the movable plate 13 is fixedly connected to the movable column 17, one end of the movable plate 13 extends out of the slide groove 16, and the end of the movable plate 13 extending out of the slide groove 16 is used to press the button 15 under the drive of the movable column 17.
[0021] A base 10 is fixedly connected to the bottom of the stretching die 1, and a rotating shaft 21 is rotatably connected to the base 10.

The PtRh3 alloy passes through the cleaning brushes 11 to clean the surface of the PtRh3 alloy, thereby preventing impurities on the surface of the PtRh3 alloy, reducing the wear on the stretching die 1, and avoiding scratches, roughness, pitting and other defects on the surface of the PtRh3 alloy wire.
[0025] The working principle of the PtRh3 alloy stretching device provided by the present invention is as follows: After the PtRh3 alloy is stretched through the stretching die 1, when the surface is uneven, the uneven part passes through the ejector pin 12, so that the ejector pin 12 is compressed into the symmetrical trigger device 7, so that the moving plate 13 moves and contacts the button 15, so that the cylinder 19 is started, and the cylinder 19 drives the rotating plate 20 to rotate, so that the rotating shaft 21 and the steering plate 6 rotate, so that the angle of the steering plate 6 changes; at this time, the unqualified PtRh3 alloy wire that has been stretched falls to the other side through the steering plate 6, and the PtRh3 alloy wire passes through the infrared sensor 22, and the cylinder 19 is restored to its original state, so that the steering plate 6 is restored to its original state, and the qualified PtRh3 alloy wire and the unqualified PtRh3 alloy wire can be collected separately, reducing the difficulty of subsequent processing and increasing the service life of the product.
