KR-20260065272-A - Switchable bending system for processing pipes

Abstract

The present invention relates to a switch bending system for processing pipe material, comprising: a main body (10) that mounts a front station (11) and a top transfer table (15) respectively so as to be capable of multi-axis movement; a feed member (20) that supports a pipe material displaceably on the transfer table (15); a main block (30) that is mounted on the station (11) via a reverse actuator (31) and supports a vertical axis (33) rotatably at its tip; a sub-convex (40) that is fixed to the main block (30) so as to be opposite to the vertical axis (33) and causes relative movement of a first clamp (41) with respect to a bending die (35); and a movable block (50) that is integrally rotatably connected to the vertical axis (33) and causes relative movement of a second clamp (51) with respect to the bending die (35). Accordingly, when producing workpieces with relatively complex three-dimensional shapes by feeding pipe materials into the mass production site, it is possible to minimize or eliminate worker intervention while improving quality and productivity based on the reliability of the continuous process.

Description

Switchable bending system for processing pipes The present invention relates to a pipe processing device, and more specifically, to a switch bending system for pipe processing to produce a workpiece of a relatively complex shape by feeding a pipe material in mass production. Typically, pipe (tube) bending devices are widely used in various industrial fields, including general manufacturing, plumbing, automotive, and construction. Manual bending devices are used for DIY projects or custom furniture production based on their simple and inexpensive structure. However, for workpieces with three-dimensional shapes rather than two, it is preferable to use automatic bending devices to save labor and improve precision. In this case, functional features that minimize or eliminate operator intervention are preferred. Korean Registered Patent Publication No. 1062267 (Prior Art 1) and Korean Registered Patent Publication No. 2052030 (Prior Art 2) are known as prior art documents that can be referenced in relation to pipe bending. Prior art 1 includes a bending drive unit composed of a model body consisting of a rotating plate and the outer shape of a product, and a clamp that fixes a steel tube body to the rotating plate; a mandrel drive unit in which a mandrel inserted inside the steel tube body is connected to a piston of a cylinder; a support roller that guides the steel tube body and a pressure member for holding the steel tube body. Accordingly, the preparation process for bending is simplified, and improved workability and productivity are expected. Prior art document 2 includes: a pipe supply unit for supplying a pipe to be bent; a guide roller unit having a guide roller that supports the bottom surface of the pipe supplied on a second main body frame on the opposite side of the pipe supply unit; and a bending unit that bends the pipe supplied while being conveyed and rotated on one side of the second main body frame. Accordingly, the effect of securing high reliability in large pipe bending is expected. However, according to the aforementioned prior art, there is a need for improvement in that it is insufficient for mass-producing three-dimensional shaped workpieces. FIG. 1 is a perspective view showing the entire apparatus according to the present invention. FIG. 2 is a plan view showing the main parts of a device according to the present invention. FIG. 3 is a side view showing the main parts of the device according to the present invention. FIG. 4 is a front view showing the main parts of the device according to the present invention. FIG. 5 is a configuration diagram of the main operating state of the device according to the present invention. Hereinafter, embodiments of the present invention will be described in detail based on the attached drawings. The present invention proposes a switch bending system for processing pipe materials. The invention is intended for a device that feeds pipe materials into mass production to produce workpieces of relatively complex shapes, but is not necessarily limited thereto. Various pipe materials, such as steel, copper, and aluminum, can be applied. The pipe material is denoted by the symbol P1, and the workpiece is denoted by the symbol P2. According to the present invention, the main body (10) is structured to be capable of multi-axis movement, with a front station (11) and a top transfer platform (15) each mounted thereon. Referring to FIG. 1, the station (11), Z-axis synchronous motor (12), Y-axis synchronous motor (13), and feed platform (15) constituting the main body (10) appear together with the workpiece (P2). The station (11) is mounted to enable two-axis movement by interposing a Z-axis synchronous motor (12) that induces vertical movement and a Y-axis synchronous motor (13) that induces horizontal movement on the front of the main body (10). The Z-axis synchronous motor (12) and the Y-axis synchronous motor (13) can be implemented by connecting a ball screw-nut block or a rack-pinion to an LM guide. The feed platform (15) has the function of gripping a straight pipe material of a set length, feeding it in the X-axis direction in units of a set length, and rotating it around the axis center. The workpiece (P2) exemplified in the present invention has a three-dimensional shape having four bending sections (R1), (R2), (R3), and (R4), but is not limited thereto and various three-dimensional shapes are possible. The dimensions of the first bending section (R1) and the fourth bending section (R4) are the same, and the dimensions of the second bending section (R2) and the third bending section (R3) are also the same. In this case, as described below, the four bending sections (R1), (R2), (R3), and (R4) are formed sequentially and continuously. In addition, according to the present invention, the feed member (20) has a structure that supports the pipe material displaceably on the conveyor (15). Referring to FIGS. 1 and 2, the pipe material (P1) is loaded onto a trans
