[CN 201811120950.2] screw guide rail type multi-station cold heading machine
[CN 201811120950.2] Title of screw guide rail type multi-station cold heading machine: application number of screw guide rail type multi-station cold heading machine: CN 201811120950.2 applicant: Jiangsu Tianyi cold heading co., ltd. application date: 2018-9-26 patent type: invention application the present invention relates to the technical field of cold heading machine, especially the screw guide rail type multi-station cold heading machine, including a machine tool body, a main die holder is installed above the machine body, one side of the main die, one side of the die slider is provided with a floating device, one side of the main die base is fixed with a main die core, a number of guide rail holes are arranged under the main die hole, both ends of the guide rail are provided with cylindrical holes, and the die slider One side is fixed with a die core, and the floating device includes a sleeve column, a spring ring and a fixed cover; the present invention connects the die slider with the main die base by setting several groups of guide rails, and made of high carbon chromium bearing steel, make it wear-resistant and hard, so as to ensure the concentricity between the die slider and the main mold base, and avoid the product from being concentric. By setting a floating device at one end of the guide rail, the guide rail installation is convenient and the guide rail installation is not parallel. The accuracy of the cold heading machine is reduced, thereby effectively improving the quality of the product.
