\n\t1. Protective devices for hazardous mechanical transmission mechanisms require that all moving parts be shielded to prevent contact with any part of the body. Fixed protective devices, manufactured according to the shape and size of the protected parts, are installed on the outside of the transmission mechanism to prevent human contact with the dangerous rotating parts of the machine. Main protective measures:<\/p>\n
\n\t\u2460 NudityGear<\/strong>The transmission system must be equipped with a protective cover;<\/p>\n \n\t\u2461 All chain drives less than 2 meters above the ground must be equipped with protective covers; if they are above passageways, they must have protective barriers below to prevent damage.sprockets<\/strong>It broke and fell, injuring people;<\/p>\n \n\t\u2462 Protective covers should be used on dangerous parts of the drive belt, and it should be installed vertically whenever possible. The drive belt tension should be appropriate.<\/p>\n \n\t\u2463 Use anti-static transmission belts, and maintain a high humidity level in the work area. Install grounded metal brushes to conduct the static charge of the belt to the ground, or make the transmission belt conductive and grounded to prevent static sparks.<\/p>\n \n\t2. Protection against hazards from punching, shearing, and pressing machinery<\/p>\n \n\tThe most important aspect of punching and shearing equipment is having a reliable clutch and brake, ensuring high reliability in starting, stopping, and transmission braking. Secondly, the machine must have reliable safety protection devices. These devices prevent the clutch from engaging or the pressure slide from sliding down when the operator's limbs enter the danger zone. Commonly used safety protection devices include anti-slip devices, safety buttons, and multi-person start buttons.<\/p>\n \n\t(1) The anti-clutching device uses a cam machine to lock and release the clutch to prevent clutch failure. During use, the pedal must be released in each stamping operation before the next stroke can begin; otherwise, the press will not operate.<\/p>\n \n\t(2) Safety button for press. The working principle is that when the button is pressed once, the press slide moves only one stroke and does not rotate continuously, which can protect the operator's hand.<\/p>\n \n\t(3) Two-hand or multi-person start-up device. Its function is to require the operator to use both hands simultaneously to start the device. This removes both hands from the danger zone and prevents the situation where one hand starts the device while the other hand is still in the danger zone when operating with one hand. Multi-person start-up is to prevent injury caused by poor coordination.<\/p>\n \n\t(4) Before each day's work, check the punching and shearing press (clutch, brake, safety devices). If any problems are found, repair them immediately to ensure they are in good working order. When stopping the machine for maintenance, take protective measures and hang warning signs in a conspicuous place to prevent accidents caused by sudden machine restart.<\/p>\n \n\t(5) Organize the workspace and remove all unnecessary items to prevent them from falling onto the switches during operation and causing the equipment to start suddenly and cause an accident. Clean up any debris on the ground around the machine to prevent slipping or tripping during operation.<\/p>\n \n\t3. Protection against hazards from machinery and equipment<\/p>\n \n\tProtecting machinery and equipment from hazards requires not only reasonably designed, reliably installed protective devices that do not interfere with operation, such as protective covers, guardrails, and safety railings; but also the installation of safety devices, such as overload protection devices, travel safety devices, braking devices, and sequential action devices to prevent misoperation. A power cut-off switch is also necessary. To prevent accidental activation by human contact, the start button should be protected by being either enclosed or recessed. Furthermore, the production area should have sufficient lighting, and each machine should have appropriate local lighting, maintaining a safe distance. For machinery and equipment whose noise levels exceed national standards, noise reduction measures should be implemented.<\/p>","protected":false},"excerpt":{"rendered":" 1\u3001\u673a\u68b0\u4f20\u52a8\u673a\u6784\u5371\u9669\u7684\u9632\u62a4 \u4f20\u52a8\u88c5\u7f6e\u8981\u6c42\u906e\u853d\u5168\u90e8\u8fd0\u52a8\u90e8\u4ef6\uff0c\u4ee5\u9694\u7edd\u8eab\u4f53\u4efb\u4f55\u90e8\u5206\u4e0e\u4e4b\u63a5\u89e6\u3002\u6309\u9632\u62a4\u90e8\u5206\u7684\u5f62\u72b6\u3001\u5927\u5c0f\u5236 […]<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4],"tags":[],"class_list":["post-684","post","type-post","status-publish","format-standard","hentry","category-chain-sprockets"],"blocksy_meta":{"styles_descriptor":{"styles":{"desktop":"","tablet":"","mobile":""},"google_fonts":[],"version":6}},"_links":{"self":[{"href":"https:\/\/www.jiansujichilun.com\/en\/wp-json\/wp\/v2\/posts\/684","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.jiansujichilun.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.jiansujichilun.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.jiansujichilun.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.jiansujichilun.com\/en\/wp-json\/wp\/v2\/comments?post=684"}],"version-history":[{"count":0,"href":"https:\/\/www.jiansujichilun.com\/en\/wp-json\/wp\/v2\/posts\/684\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.jiansujichilun.com\/en\/wp-json\/wp\/v2\/media?parent=684"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.jiansujichilun.com\/en\/wp-json\/wp\/v2\/categories?post=684"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.jiansujichilun.com\/en\/wp-json\/wp\/v2\/tags?post=684"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
