A Variety Expansion Tube Positioning Tool and Its Working Method and Application

Abstract

The invention discloses a variable expansion tube positioning tool comprising an expansion tube positioning tool plate. The expansion tube positioning tool plate is fixedly connected to a workbench. A plurality of parallel horizontal positioning strips and a plurality of parallel vertical positioning strips are arranged on the expansion tube positioning tool plate in the horizontal and vertical directions respectively. Workpieces as required are clamped on the expansion tube positioning tool plate through fixing clamp strips according to length and width requirements of the workpieces. Positioning holes are formed in the fixing clamp strips, and bolts are penetrated the positioning holes and the horizontal positioning strips or the vertical positioning strips to cooperate with nuts to fix the fixing clamp strips to the expansion tube positioning tool plate. The variable expansion tube positioning tool is simple and convenient and applicable to positioning of all heat exchanger expansion tubes, tool input of enterprises is reduced, and production cycle of heat exchangers is accelerated to achieve competitive advantages of the heat exchanger industry.

Description

technical field [0001] The invention belongs to the field of heat exchangers, and in particular relates to a variable expansion tube positioning tool and its working method and application. Background technique [0002] Most heat exchanger companies mainly produce non-standard heat exchangers. The characteristics of non-standard heat exchangers are as follows: the product specifications and models are too complicated, and there are many products with strange shapes. Generally, non-standard orders account for more than 80% of the total order batches. , At the same time, most of the non-standard orders and single heat exchanger models do not exceed 3 heat exchangers, and the proportion is more than 50%. The expansion tube tooling of traditional non-standard heat exchangers is one model and one, and they are all tailor-made, so it is difficult to manage the tube expansion tooling, and the design cost and the production cost of the tooling itself are relatively high. Compared wi...

Problems solved by technology

The expansion tube tooling of traditional non-standard heat exchangers is one model and one, and they are all tailor-made, so it is difficult to manage the tube expansion tooling, and the design cost and the production cost of the tooling itself are relatively high. Compared with other heat exchanger manufacturers , there is no obvious competitive advantage in terms of price and product production cycle, and the production cycle of expanding tube tooling is relatively long
