Advantages of vertical tube expander

Vertical tube expander is a kind of special equipment for producing various heat exchange equipment in industrial processing. Different from other types of tube expanders, the vertical layout is adopted. The equipment is composed of base, guide pillar, oil cylinder, hydraulic station, workpiece clamping device and electric control box. So what's the advantage of this arrangement? Let's take a look at the working advantages and product advantages of the vertical tube expander

1、 Introduction to machining principle

Its working principle is to insert the expanding rod and the expanding head into the copper tube of the heat exchanger through hydraulic transmission, so as to make the copper tube plastic deformation, so that the copper tube and fin are in close contact.

2、 Advantages

1. The process of expanding, expanding and flanging can be completed in one working cycle to save raw materials.

2. The heat treatment method is adopted for the expanding rod and expanding head of the equipment, so that both the hardness and toughness of the expanding rod are improved at the same time, thus increasing the service life of the equipment.

3. High precision, high degree of automation.

4. The expansion rod fixing device adopts groove and retaining plate positioning, and the expanding rod adopts cylinder positioning, so the loading and unloading is more convenient and flexible.

5. Automatic material return.

6. The operation is convenient and simple, which reduces the labor of workers and improves the production efficiency.

7. The length of the workpiece does not change and no shrinkage deformation occurs when the tube is expanded again, which can save 3 ~ 5% of the raw materials.
