The use and introduction of mandrel

The new type of elbow mandre mold is mainly used to push the elbow is not thick and will not thin. It is possible to use the steel pipe with equal wall thickness to push the elbow with equal wall thickness.Greatly reduce the cost of material production.

The new type of elbow made of orange push elbow does not need to use a press for two shaping, its Angle is directly the standard.The new mandrel push elbow time is short, improve the production efficiency, the new mandrel has the traditional mold production cost is reduced by about 30%, the production efficiency is increased by one to two times.

The material of mandrel generally has K18, 2520, 18-8, 304 and so on. The high temperature strength and wear resistance gradually increase.The price is also increased accordingly. The push elbow mandrel head is divided into three kinds: single curvature, double curvature and multiple curvature according to the radius of curvature.Single curvature, double curvature, multi-curvature mandrel, thrust is gradually reduced, production cost is gradually increased, double curvature mandrel is selected in this inspection.According to the shape of the section is divided into two kinds of circular section.The circular section is simple to manufacture and low cost.But the ellipticity and thinning rate of the push elbow is too large, the elliptical section is complicated and the cost is high, but different from the butt-welding elbow, the ellipticity and thinning process of the push elbow is small.The selection of elliptical cross-section mandrel, according to whether there is a shaping segment is divided into shaping segment mandrel and no shaping segment mandrel two kinds.The mandrel with shaping section is complicated, high cost and long use time, while the mandrel without shaping section is simple and low cost.Our company and professional debugging finished elbow.Our products are trusted and praised by customers, and become the partner of many customers.

The company mainly produces elbow machine, pipe bender, tee machine, pipe expanding machine, beveling machine, press and other above pipe fittings equipment mold.With a complete scientific quality and management, the recognition of many customers.Our company can directly customize various types of elbow mandrel according to the needs of customers.

The type of elbow mandrel produced by our company is 60-610, and the material of elbow mandrel is generally K18,2520.18-8.304, etc.The company's production of mold to improve production efficiency, long use time.The mandrel is simple to make and low cost.The mandrel type push elbow is one of the most important innovative die.

Advantage of expanding machine equipment system: reproduction interchanged when expanding intermediate frequency power supply will be heated to intelligent control needed to maintain a constant temperature, effectively avoid human factors caused by the steel pipe and the mould under high temperature to produce steel pipe quality scrap, at the same time avoid the low temperature in the system of push mold interchanged fracture phenomenon, cause the unsafe factors.Compared with manual operation, it is energy saving and environmental friendly, simplifies the operation procedure and reduces the labor cost.The hydraulic pipe expander is equipped with two intelligent temperature measurement and automatic temperature control, so that the pipe expander can set the heating temperature according to different pipes, select the heating temperature of pipes and keep it constant, display and record in real time, and save the parameters of heating temperature.
