Embodiment 1

[0035] refer to Figure 1-Figure 8 , a metal profile forming device, including a pipe 1 for triangular pipe production, the pipe 1 is covered with an outer extruding mechanism 2, and the outer extruding mechanism 2 is used to flatten the side wall of the triangular pipe, and the The outer extruding mechanism 2 is a triangular shaft rolling structure, which includes a connecting block 201 and a roller 202. The inner extruding mechanism 3 is sleeved inside the pipe material 1, and the inner extruding mechanism 3 is used for triangular The corners of the tube are formed, and the inner extrusion mechanism 3 is a triangular wheel rolling structure, which includes a mounting seat 301 and an extrusion wheel 304;

[0036] The device fully considers the cost of production equipment and the cost of learning the skills of operators. The inner extrusion mechanism 3 and the outer extrusion mechanism 2 can be used to shape the common stainless steel thin-walled round tubes to obtain triangu...

Embodiment 2

[0044]A metal profile forming method, applied to the above-mentioned device, said method comprising the following steps:

[0045] S1. Prepare a stainless steel thin-walled round pipe as the raw material pipe 1, and use tooling to support one end of the pipe 1, so that the subsequent use of the inner extrusion mechanism 3 and the outer extrusion mechanism 2 can be used for spinning under the pull of the cable 4;

[0046] S2. Pass the cable 4 connected to the shaping block 306 through the pipe material 1, pull the cable 4 so that the round end of the shaping block 306 is inserted into the pipe material 1, and continue to pull the cable 4 relative to the pipe material 1, so that the pipe material 1 is located in the inner extrusion The part in front of the movement direction of the mechanism 3 initially obtains an approximately triangular outline under the extrusion of the shaping block 306, and the inner extrusion mechanism 3 has not yet fully entered the pipe 1;

[0047] S3. Ap...

Embodiment 3

[0050] The difference from Example 1 is that when the requirements for the edge shape of the triangular tube are relatively low, only the outer extruding mechanism 2 can be used for the final rolling operation, and the obtained edge of the triangular tube will have obvious radians.

Abstract

The invention discloses a hardware profile forming method and device, relates to the field of hardware profile production, and provides the following scheme aiming at the contradiction between a lower yield demand and high production cost of an existing triangular pipe. The hardware profile forming device comprises a pipe for triangular pipe production, and the pipe is sleeved with an outer extrusion mechanism; and the outer extrusion mechanism is used for flattening the side wall of the triangular pipe, the outer extrusion mechanism is of a triangular shaft rolling structure and comprises connecting blocks and rolling shafts, an inner extrusion mechanism is connected into the pipe in a sleeved manner, the inner extrusion mechanism is used for forming edges and corners of the triangular pipe, the inner extrusion mechanism is of a triangular wheel rolling structure and comprises a mounting seat and an extrusion wheel, the six groups of rolling shafts and the three groups of connecting blocks are arranged in a triangular prism shape, and the three groups of connecting blocks are located on three groups of edges. According to the device and method, the contradiction between the lower yield requirement and the high production cost of the existing triangular pipe is effectively solved.

Description

technical field [0001] The invention relates to the field of hardware profile production, in particular to a method and device for forming a hardware profile. Background technique [0002] Hardware profiles cover a large range, but the common hardware profiles in life are mainly rod-shaped assembled profiles, mostly metal materials, the most typical such as stainless steel thin-walled square tubes, round tubes and other tubes, in addition to common square tubes, round tubes In addition to pipes, there are also some special-shaped pipes with triangular cross-sections that are in low demand. For manufacturers, facing the market demand for triangular pipes on the market, it is obvious to introduce spinning production lines for triangular pipes under the condition of low shipments. The benefit is low, the cost is high, and it is very easy to cause losses. At this time, a low-cost, light and easy-to-use equipment is needed to meet the production needs of a small amount of triangu...
