Service HotlineGuangdong Yueluo Hardware Industry Co., Ltd. provides a shaft retaining ring in order to solve the above problems. The plan of Guangdong Yueluo Hardware Industry Co., Ltd. is a shaft retaining ring realized in this way, which is composed of a shaft washer, a torsion spring, a positioning pin and a limit pin. It is characterized in that the shaft washer is provided with two symmetrical distribution gaps. a circular ring, and a groove is provided at the vertical notch on one side, and a stepped through hole is provided on the side notch facet of the groove to cooperate with the limit pin, and the two sides of the groove are provided with a through hole and a locating pin Matching; the limit pin is a stepped short shaft. The beneficial effects of Guangdong Yueluo Hardware Industry Co., Ltd. are simple structure, low production cost, convenient and reliable use.
Ordinary thread Ordinary coarse thread: Feature code M+ Nominal diameter + Rotation + thread tolerance zone code (pitch diameter, top diameter) - Rotation length Ordinary fine thread: Feature code M+ Nominal diameter * thread pitch + direction of rotation + thread tolerance With code (middle diameter, top diameter) - the length of screwing is omitted for right-handed threads, and the left-handed thread is represented by LH. M 16-5g6g means coarse thread ordinary thread, nominal diameter 16, right-handed, the thread tolerance zone is 5g in the middle diameter and 6g in the major diameter, and the screwing length is considered as the medium length. M16×1 LH-6G means fine thread ordinary thread, nominal diameter 16, pitch 1, left-handed, thread tolerance zone medium diameter and major diameter are both 6G, and the screwing length is considered as medium length. The labeling format is: feature code (cylindrical pipe thread is represented by G, conical pipe thread is represented by NPT) + size code + tolerance grade code + rotation direction G1A--LH represents inch non-threaded sealing pipe thread, size code 1in, left-handed, tolerance The grade is A grade. Rcl/2 means inch thread seal taper pipe thread, size code 1/2in, right-handed.
A screw belt structure, especially a screw belt that can position the screws on the screw belt, so that the screws do not swing, so that the screws can be stably aligned with the points where the screws are to be screwed, and the screw fixation of the screws is facilitated. In its overall implementation and use, the innovative design of the screw belt structure increases the practical function characteristics.
However, this process scheme has high cost, low efficiency, and has certain difficulties in quality assurance. In order to ensure product production efficiency, reduce manufacturing costs and improve product quality, it must be considered that the blank forming is completed on a multi-station cold heading machine at one time.
In real life, rivet nuts are used. With different specifications and different uses, many people are familiar with this tool but don't know how to use it properly. In fact, rivet nut tools have manual and transmission, and now are rarely used for manual. If you choose to use electric rivet nuts in order to improve production efficiency, which of the two is more widely used? The following describes the use of electric rivet nuts and manual nuts. How to use the manual rivet nut tool: Insert the rivet nut into the drilled installation hole with a rivet mother tool to fix the rivet nut. (1) Screw the rivet nut onto the rivet nut tool 2) Use the rivet nut tool to insert the rivet nut into the drilled mounting hole. (3) Tighten the nut, and press the handles on both sides of the rivet nut tool to the direction of the middle round rod. You can only press it hard. Therefore, this pressure must be in place. It is forbidden to repeatedly squeeze the handles on both sides to damage the nut. Fastening thread in the form of inside. (4) The rivet nut tool is separated from the rivet nut: just loosen the ball head in the picture, and the tool will be separated from the nut after completely loosening.
