The technical field of niobium tube relates to a butterfly-shaped niobium tube processing device, in particular to a butterfly-shaped niobium tube processing device. High light efficiency sodium lamp is the national recommended energy-saving environmental protection products, but also the domestic and foreign light source enterprises vigorously development direction. High luminous sodium lamp series products have high luminous efficiency, which are used for urban road lighting, industrial and mining enterprise site lighting, market lighting, etc. The lamp emits a bright yellow light, has certain fog-permeable light color, high reliability and high efficiency. Niobium tube is one of the key components in sodium lamp products. The niobium tube connects the electrode with the ceramic tube to realize gas sealing connection. The quality directly affects the lamp's life.
The extruding die is used to form the extruding developing part, which is located between the positioning rod and the pushing rod. It is composed of the first and second extruding dies which are set opposite to each other, and the extruding direction of the extruding die is perpendicular to the axis direction of the positioning rod and the pushing rod.
Optimization, referred to the positioning of the rod by locating rod of a linked in sequence, positioning rod and locating rod three, described the push rod in turn connect by putting a and push rod composition, in the process of niobium tube by locating rod part a and putting don't arrive at opposite ends of niobium tube semi-finished products and the positioning rod 2 and putting two into niobium tube semi-finished products of niobium tube semi-finished product positioning, the positioning rod three for limits of extrusion die extrusion.
Preferably, the first extrusion die and the second extrusion die are provided with an extrusion surface matching the extrusion developing part, and the two positioning rods and two pushing rods point to the end of the inner end of niobium tube semi-finished products, which are in a tapered shape, and are matched with the spreading part of the butterfly niobium tube.
Preferably, the diameters of the positioning rod 1, 2 and 3 are successively reduced, the diameters of the putting rod 1 and 2 are successively reduced, and the diameters of the positioning rod 2 and 2 are matched with the inner diameter of the tube part of the butterfly niobium tube.
Preferably, the device also includes a feeding turntable, and the edge of the feeding turntable is uniformly arranged with multiple workpiece placement positions along the circumference. The positioning rod and push rod are arranged at the edge of the feeding turntable and are separated on both sides of the feeding turntable.
