High-precision cold-drawing equipment for high-smoothness corrosion-resistant stainless steel seamless steel tubes

Abstract

The invention discloses high-precision cold-drawing equipment for high-smoothness corrosion-resistant stainless steel seamless steel tubes, which comprises a cold-drawing table body, wherein a transmission mechanism is arranged on the cold-drawing table body, a moving trolley is connected to the transmission mechanism, a traction clamp is mounted on the moving trolley, a cold-drawing die is arranged on the cold-drawing table body; a plurality of supporting material receiving plates are arranged on one side of the cold-drawing table body at equal intervals, the bottom ends of the multiple supporting material receiving plates are all connected with moving mechanisms, and a transmission device is arranged on one side of the moving trolley. According to the high-precision cold-drawing equipment for high-smoothness corrosion-resistant stainless steel seamless steel tubes, in the process that a traction trolley conducts cold drawing on the steel tube through the traction clamp, the transmission device sequentially drives the multiple moving mechanisms to operate, so that multiple supporting material receiving plates sequentially move in the direction of the cold drawing table body and support the moving cold-drawn steel tube; and after cold drawing of the steel tube is completed through the traction trolley, the multiple supporting material receiving plates are driven by the transmission device to move in the direction of the cold drawing table body. After the traction pulley performs cold drawing of the steel tube, the multiple supporting material receiving plates synchronously guide the steel tube out of the cold drawing table body.

Description

Technical field [0001] The present invention relates to the technical field of seamless steel pipes, and is specifically a high-precision cold-drawing device for highly high-optical and corrosion-resistant stainless steel seamless steel pipes. Background technique [0002] High-optical and corrosion-resistant stainless steel pipe is a high-precision steel pipe after cold rolling or cold cutting. Since the internal and outer walls of the precision seamless steel pipe, with the advantages of high pressure without leakage, high precision, high degree of cleansing, cold bending, expansion, flat-free crack, etc., mainly used to produce pneumatic or hydraulic components, such as Cylinders or cylinders are seamless tubes. [0003] Cold pull-is a processing process of the material, for metal materials, cold extension refers to a certain shape and a certain mechanical properties, and draws under normal temperature conditions. Cold pull products are advantages with high dimensional precisi...

Problems solved by technology

[0004] At present, when the existing seamless steel pipe is cold-drawn, it is necessary to use a tractor to cooperate with the traction tongs to cold-plate the steel pipe. However, although the existing tractor is supported by the track on the workbench, it is relatively The workbench moves back and forth to cold-draw the cold seamless steel pipe. However, during the cold-drawing process of the tractor, due to the wear of the track, and the overall use of the tractor for a long time, the whole is prone to shaking when moving. As a result, the tractor tends to vibrate during the cold drawing process of the long steel pipe, which leads to the bending of the steel pipe. At the same time, when the steel pipe is unloaded, because there is no guiding device, the steel pipe directly falls, which further easily leads to The phenomenon of steel pipes colliding with each other, for this reason, we propose a high-precision cold-drawing equipment for high-gloss, corrosion-resistant stainless steel seamless steel pipes
