Service HotlineThe existing screw generally includes a round table-shaped nail body with one large end and one small end, a threaded section is provided on the radial circumference of the nail body, a small end of the nail body is provided with an inclined tip, and the large end of the nail body is provided with a nail cover. , generally used on materials that are softer than the screw, and drill into the object to be nailed through its own rotation. When drilling, the thread plays the role of rotary cutting, so that the screw is drilled forward, but when the thread cuts the object to be nailed When it is shaken for a long time, the tightening force of the screw in the axial direction is not enough, it is easy to loosen, and there is a potential safety hazard.
double-headed pin puller includes a slider hammer and a sliding rod, two ends of the sliding rod are respectively provided with different types of pin-pulling parts, the pin-pulling parts are threadedly connected with the sliding rod, and the sliding rod is also provided with There is a sliding rod limit block, and the sliding rod is slidably connected with the slider hammer. The double-headed pin puller can install two types of pin-pulling heads at the same time, and can pull out two different types of pins. It is easy to use and has high work efficiency. Disadvantage: Single function, cannot be used to install pins.
There are many types of rivets, including dome head, flat head, blind rivet and so on. When riveting parts, they will have uneven force and affect the quality of riveting. Some rivet caps are too thin to easily affect the quality of riveting. Some rivets have poor tightness of riveted parts when riveting. Therefore, both the structure of the rivet and the tightness of the riveting need to be considered, so as to enhance the quality of the rivet fastening.
Most of the existing screws use an integral metal structure, and there are still some problems, such as large weight, high cost of materials, wear resistance, hardness, rust resistance, corrosion resistance, high and low temperature resistance, brittleness, toughness, etc. Many occasions cannot meet the needs of production, and further improvements are needed to improve production efficiency, reduce costs, improve safety, and prolong the service life of screws.
At present, the automatic nailing device on the domestic market lacks the restraint and arrangement of the rivets when they are out of the nailing device, which makes the rivets irregular and uncontrollable after the automatic nailing is completed, which has adverse effects on on-site use and maintenance, and is unstable. .
