Embodiment 1

[0037] Embodiment 1 of the present invention provides a processing and manufacturing device for seamless pipes. The processing and manufacturing device for seamless pipes includes a first workbench 1 and a second workbench 2, wherein the first workbench 1 is placed above the second workbench 2; in this embodiment, the first workbench 1 is at the Move in a horizontal plane and be provided with upsetting rod 3, piercing needle 4 and extruding die 5 on it toward the side of second workbench 2; Position 6 and Extrusion Station 7, Extrusion Station 7 is provided with a through hole 8 that runs through the second workbench 2. In addition, the first workbench 1 and / or the second workbench 2 are connected with a drive unit (not shown in the figure), and the drive unit drives the first workbench 1 and the second workbench 2 to move relatively, and makes The upsetting rod 3 and the perforating needle 4 move to the upsetting station 6, and the extrusion die 5 moves to the extrusion stat...

Embodiment 2

[0055] According to another aspect of the present invention, Embodiment 2 of the present invention provides a method for processing and manufacturing a seamless pipe. The processing and manufacturing method uses the device for processing and manufacturing a seamless pipe as in Embodiment 1.

[0056] The seamless pipe processing and manufacturing method provided in Embodiment 2 of the present invention can complete the entire extrusion process of large seamless pipes in one fire by using the seamless pipe processing and manufacturing equipment in Embodiment 1. The entire extrusion process except the initial After manual blanking 15 is placed on the mobile workbench, the whole process of dephosphorization, upsetting, perforation, bottom cutting, extrusion, and residual punching and shearing can be completed automatically, with a high degree of automation and high production efficiency, which effectively simplifies the large-scale seamless Tube manufacturing process. Moreover, si...

Abstract

The invention relates to the field of machining, and discloses a machining and manufacturing device of a seamless tube and an application method of the machining and manufacturing device. The machining and manufacturing device of the seamless tube comprises a first workbench and a second workbench. An upsetting rod, a perforating needle and an extrusion mold are arranged on the side, close to thesecond workbench, of the first workbench. An upsetting station and an extrusion station are arranged on the second workbench, and a through hole penetrating through the second workbench is formed in the extrusion station. The first workbench and / or the second workbench are / is connected with a drive unit. The drive unit drives the first workbench and the second workbench to relatively move, and under different procedures, the upsetting rod and the perforating needle move to the upsetting station and the extrusion mold moves to the extrusion station. According to the machining and manufacturingdevice of the seamless tube, the whole extrusion process of the large seamless tube can be completed in one step simply by adjusting the relative positions of the first workbench and the second workbench, the automation degree and the production efficiency are high, and the step of independently arranging multiple stations is omitted.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a processing and manufacturing device for a seamless pipe and a use method thereof. Background technique [0002] The plastic processing and manufacturing method of metal materials is mainly a processing and manufacturing method in which metal materials are plastically deformed under pressure and then formed. Among them, extrusion is one of the main manufacturing methods for producing large seamless pipes. The extrusion manufacturing of large seamless pipes, especially the extrusion manufacturing of large seamless pipes made of high-temperature and difficult-to-deform metal materials, needs to be extruded on extrusion dies of more than 10,000 tons. In this case, not only extrusion dies of 10,000-ton level or more are required, but also at least one billet-making equipment for upsetting and piercing is required, and most of them also need supporting dephosphorization equipment....
