Description

Technical Field

[0001] The utility model relates to the technical field of tungsten-molybdenum rod blanks, in particular to a drawing device for producing tungsten-molybdenum rod blanks. Background Art

[0002] Tungsten alloy is a kind of alloy based on tungsten and added with a small amount of Ni.Cu, Fe.Co.Mo, Cr and other elements. It is commonly known as high specific gravity alloy, heavy alloy or high-density tungsten alloy. Tungsten alloy is widely used in electronics and electric light source industries. It is also used in aerospace, casting, weapons and other departments to make rocket nozzles, die-casting molds, armor-piercing cores, contacts, heating elements and heat shields. To process tungsten alloy into metal rods, it is necessary to use a drawing machine to apply tension to the metal blank so that it passes through the die hole to obtain plastic forming of products with the same size and shape as the die hole.

[0003] Application No. 202221566521.X discloses a drawing device for producing tungsten-molybdenum rod blanks. When in use, the tungsten-molybdenum rod blank is placed horizontally in the lower arc-shaped groove, and the U-shaped plate is driven down by a hydraulic cylinder, thereby causing the upper clamping die to descend, so that the upper clamping die and the lower clamping die cooperate to clamp the tungsten-molybdenum rod blank. After clamping, the motor is started to drive the active bevel gear to rotate, and the active bevel gear meshes to drive the driven bevel gear to rotate, thereby rotating the lead screw. After the lead screw rotates, the displacement block is driven to move inside the slide groove through the thread, thereby driving the clamp assembly to move. The drawing of tungsten-molybdenum rod blank is realized and completed. After completion, the hydraulic cylinder is started to contract to raise the upper clamping die, and then the drawn tungsten-molybdenum rod blank can be taken out. When it is necessary to adapt to tungsten-molybdenum rod blanks with different diameters, the fasteners are unscrewed, the lower clamping die and the upper clamping die can be disassembled, and then the replaced lower clamping die and the upper clamping die are placed between the two pads and on the inner side of the U-shaped plate respectively, and then the lower clamping die and the upper clamping die are fixed with fasteners, so as to achieve the clamping of tungsten-molybdenum rod blanks with different diameters, and tungsten-molybdenum rod blanks with different diameters can be drawn.

[0004] When the device is drawing tungsten-molybdenum rods of different sizes, the upper clamp and the lower clamp need to be frequently replaced and placed between the two pads and inside the U-shaped plate, which results in a great waste of time and affects the processing efficiency. Therefore, a drawing device for the production of tungsten-molybdenum rod blanks is needed. Utility Model Content
