Service HotlineThe embedded nut proposed by Guangdong Yueluo Hardware Industry Co., Ltd. is used to be embedded in an injection molded part. The embedded nut is arranged in a column shape and has a screw hole inside. The embedded nut includes an outer peripheral surface and is formed in the inner nut. The upper end surface and the lower end surface of the two ends of the embedded nut are provided with knurling on the outer peripheral surface, and a guide surface is formed at the connection between the outer peripheral surface and the lower end surface.
However, although the existing screw can meet the function of connecting and tightening objects, its structure includes a head and a threaded rod connected with the head. Since it only has one threaded rod, it does not have a two-way connection function and cannot be satisfied with the Some special use requirements bring inconvenience to use.
self-locking nut is a nut that can self-lock by friction. The general nut will loosen itself due to vibration and other reasons during use. In order to prevent this phenomenon, the self-locking nut was invented. The main functions of self-locking nuts are anti-loose and anti-vibration. For special occasions. Its working principle is generally self-locking by friction. The types of self-locking nuts classified by function include those with nylon rings, those with neck closures, and those with metal anti-loosening devices. They are all effective torque type lock nuts (see GB/T3098.9-2002 national standard).
In the prior art, there are two ways to feed the screws of the locking screw machine, the air blowing type and the air suction type. The air suction type is suitable for relatively small screws. If the screw size is larger than M2, smaller than M5, and the length-diameter ratio is larger than 1.7, the air-blown screw machine can be selected.
rivet dismantling method and a dismantling device thereof. The dismantling method firstly places a riveting piece with a failed rivet installed on a die having a blanking hole, and then uses a punch that coincides with the center line of the rivet on the riveting piece to impact the rivet. , the rivet falls into the blanking hole under the impact of the punch to complete the disassembly; the dismantling device includes a concave die for positioning and supporting the riveting piece installed with the failed rivet, and the concave die is provided with a blanking hole; The upper part of the die is provided with a punch for punching the rivet into the blanking hole, and the punch and the center line of the rivet are coincident; Yueluo adopts the punch to dismantle the failed rivet, which not only has high work efficiency, but also has high work strength. It is small, and does not damage the riveting parts on which the rivets are installed; the impact process will not cause the rivets to splash, and the safety is high; and the cost of dismantling equipment is low.
