Sliding seat of plastic corrugated-pipe forming machine and machining process of sliding seat

Abstract

A sliding seat of a plastic corrugated-pipe forming machine comprises a sliding seat body and a rack which is detachably fixed on the sliding seat body. The machining process of the plastic corrugated-pipe sliding seat includes: 1), machining a rack mounting surface on the sliding seat body and machining a rack positioning structure on the rack mounting surface, and correspondingly, machining a binding surface of the sliding seat body on the rack; 2), machining a plain hole used for being connected with a rack screw in the sliding seat body and machining a corresponding screw hole in the rack; 3), fixing the rack in the sliding seat body through the screw. The plastic corrugated-pipe sliding seat has the advantages of simple structure, easiness in machining and manufacturing and convenience in maintenance; the machining process of the plastic corrugated-pipe sliding seat is clear in process, machining speed is favorably increased, and machining and manufacturing cost is lowered.

Description

technical field [0001] The invention relates to a plastic corrugated pipe production line, in particular to a sliding seat structure of a transmission mechanism of a rail-type pressure water-cooled forming machine in a plastic corrugated pipe forming machine and a processing technology for the sliding seat structure. Background technique [0002] Plastic corrugated pipe products are beautiful, light and durable, and are widely used in various fields. After nearly 30 years of development, plastic corrugated pipes have been relatively mature in terms of equipment, molding technology, process and raw materials. The material of plastic corrugated pipes has gradually expanded from PVC to PE, PP and other raw materials, and the diameter of plastic corrugated pipes has gradually become Development in the direction of large diameter. [0003] There are two types of plastic bellows, one is completely airtight and watertight, such as used for propellant delivery of launch vehicles, g...

AI Technical Summary

Problems solved by technology

However, the efficiency and cost of processing the rack by the machining center are very low, and the precision requirement of the rack is not as good as that of the sliding seat body. At the same time, the rack will be worn after a long time of operation, so the existing plastic bellows forming machine will be damaged by the gear The integrated structure composed of the sliding seat body and the rack is replaced as a whole due to the wear of the rack

As mentioned above, such a replacement needs to replace the sliding seat body that does not need to be replaced originally, so the cost of such a replacement is very high, which will greatly increase the use and maintenance cost of the plastic bellows forming machine
