Embodiment Construction

[0026] Please refer to Figure 2 to Figure 6 As shown, the following combines a specific electric heating tube plane numerical control bending method, and its technological process is:

[0027] Parameter setting: first, input the pre-set parameters into the drive control system according to the specified requirements.

[0028] Pipe laying process: first put the straight heating pipe into two sets of clamping molds, and the heating pipe is placed in the center of one side.

[0029] Pipe taking process: open the automatic button set in the main frame, the first bending clamping mechanism 9 automatically clamps the heating tube, the feeding clamping mechanism 10 clamps the heating tube, and moves to the set bending position, after the first bending clamping mechanism 9 is released, the second bending clamping mechanism 11 clamps the heating tube and sends it to the bending machine head.

[0030] The first bending clamping mechanism 9 only clamps the heating tube, and its mechan...

Abstract

The invention relates an electrical heating tube plane numerical controlled tube bending method which comprises the technological processes of setting parameters, tube placing, tube fetching, and bending and forming, wherein the three processes of tube placing, tube fetching and bending and forming are repeated, and the parameters in a numerical controlled system are set so as to finish the wholeaction process. As the tube placing process, tube fetching process and the bending and forming process are adopted, the whole process needs no human intervention, and avoids the influence of human factors on the size, radius and angle of the bent product, thereby achieving the purposes of reducing the product fraction defective and production cost. Compared with the processing mode in the prior art, the method has the advantage of improving production efficiency; and compared with the existing processing equipment, a numerical controlled bending device adopted by the method has the advantagesof convenient operation and simple structure.

Description

【Technical field】 [0001] The invention relates to a plane numerical control bending method of an electric heating tube and a numerical control bending device using the method. 【Background technique】 [0002] Please refer to figure 1 As shown, in the prior art, in addition to the special equipment for bending machine, roll bending machine and stretch bending machine, the heating tube 1 needs to be manually bent using tools and molds. This bending method can only Use the specified radius angle, radius size and radius center distance to bend into a specified arc. The rotation center of the bending arm 2 is concentric with the bending R angle center of the heat pipe 1, the bending forming wheel 4 and the sizing roller 8 are fixed on the bending arm 2, and the clamping cylinder 5, the movable clamping block 6 and the fixed clamping The block 7 fixes the heating tube 1 on the predetermined position of the workbench 3, and rotates the bending arm 2 to drive the heating tube 1 to ...
