Abstract

The invention discloses a novel tube expander. The novel tube expander comprises a tube expanding head connection rod, wherein a first oil circuit is arranged on the inner side of the tube expanding head connection rod, a plurality of oil spray holes are formed in the head of the tube expanding head connection rod, a tube expanding head in an ellipsoidal shape sleeves the tube expanding head connection rod, an air inlet is formed in the left end of the tube expanding head, an air outlet is formed in the right end of the tube expanding head, the air inlet and the air outlet are communicated through an air channel between the tube expanding head and the tube expanding head connection rod, a plurality of tube expanding steel wires connected with one another are fixedly connected with the tail of the tube expanding head connection rod, and second oil circuits communicated with the first oil circuit are arranged on the inner sides of the tube expanding steel wires. The novel tube expander effectively reduces resistance during the operation process, smoothly discharges compressed air in a tube, and thereby reduces the number of defective products, and effectively improves product quality.

Description

technical field [0001] The invention relates to a novel pipe expander. Background technique [0002] The pipe expander is a device used to squeeze and expand one end of the pipe fittings, which can expand the opening of the pipe fittings and facilitate the connection of the pipe fittings with each other. The design of the existing pipe expander is unreasonable, the resistance is large during the pipe expansion process, the exhaust is not smooth, and the exhaust hole is blocked. In the process of product production, it is easy to cause defective products. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0004] Aiming at the above-mentioned technical problems in the related art, the present invention proposes a novel pipe expander, which can solve the above-mentioned problems. [0005] For realizing above-mentioned technical purpose, technical scheme of the present invention is realized l...
