Service HotlineEquipment that needs to be maintained at high altitude or under complex working conditions requires screw loss prevention design. Although traditional captive screws can achieve the purpose of preventing falling off, because the diameter of the screw is smaller than the major diameter of the thread, it is difficult to match the gasket, and the gasket will be eccentric, which is easy to install. Scratch the surface of the product, affecting the corrosion resistance and appearance of the product.
During the daily use and operation of mechanical equipment, due to the influence of external load, internal stress, wear, corrosion and natural erosion, individual parts or the whole change size, shape, mechanical properties, etc., which reduces the production capacity of the equipment. The consumption of raw materials and power increases, the quality of products decreases, and even personal and equipment accidents are caused. Therefore, in order to make the machinery and equipment can often play the production efficiency and prolong the service life of the equipment, the equipment must be properly repaired and routinely maintained.
Countersunk head, half countersunk head, 1200 countersunk head, half countersunk head rivets are mainly used for riveting occasions where the surface needs to be smooth and the load is not large. Flat head rivets are used for riveting occasions subject to general loads. Flat head and flat head rivets are mainly used for riveting of metal sheets or non-metallic materials such as leather, canvas and wood. Large flat head rivets are mainly used for riveting of non-metallic materials. Semi-hollow rivets are mainly used for riveting occasions with little load. Headless rivets are mainly used for riveting of non-metallic materials. Hollow rivets are light in weight and weak in head, and are used for riveting of non-metallic materials with little load. Tubular rivets are used for unloaded riveting of non-metallic materials. Nameplate rivets are mainly used for riveting nameplates on machines and equipment.
The traveling plate can be driven by the traveling cylinder to move from the lower end of the circlip sleeve rod to the lower ends of the two probes of the circlip tightening mechanism; after the two probes tighten the circlip, the traveling plate can be moved in the traveling cylinder. The tightening mechanism moves down under the drive of the lifting cylinder, the probe installs the tightened circlip in the workpiece, and then retracts the probe upward.
