Description

Floating drawing die for small-caliber special-shaped steel pipe Technical Field The utility model relates to the technical field of drawing dies, in particular to a floating drawing die for a small-caliber special-shaped steel tube. Background The small-caliber special-shaped steel pipe is a steel pipe with a smaller diameter and a non-circular cross section, and is usually subjected to custom processing and cutting according to engineering requirements, and the floating drawing die is a special drawing die and is mainly characterized in that certain parts of the die can move or float relatively freely in the drawing process so as to adapt to the deformation of metal in the drawing process. Because the abnormal steel pipe is various, need select different moulds according to the different styles of steel pipe in drawing process, then the whole change of mould, in order to install the mould, set up mounting structure in the mould outside generally, need use more materials to produce the mould when mould production, cause the extravagant of certain degree of resource, consequently, propose a small-bore abnormal steel pipe and float and draw the mould to above problem. Disclosure of utility model The utility model aims to provide a small-caliber special-shaped steel pipe floating drawing die, which aims to solve the problem of resource waste caused by integrally replacing the die. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a small-bore dysmorphism steel pipe floats and draws mould, is including being used for running through the dysmorphism steel pipe, to its mould main part that draws, the mould main part includes mould piece and mould ring, set up the through-hole unanimous with dysmorphism steel pipe shape in the middle of the mould piece, the inseparable laminating in mould piece outside has the mould ring, mould piece both sides fixedly connected with locating piece, mould ring one side is equipped with the installation component, the installation component includes rotating block, threaded rod, fixture block, thread bush and rubber piece, fixedly connected with thread bush in the mould ring, thread bush internal thread connection has the threaded rod, threaded rod one end fixedly connected with rotating block, threaded rod one end rotates and is connected with the fixture block, the spacing groove has all been seted up to one side of mould piece and mould ring. Preferably, a plurality of anti-slip strips are arranged on the outer side of the rotating block, grooves are formed in two sides of the die block, and the grooves are tightly attached to the rotating block. Preferably, the two sides of the clamping block are tightly attached to the limiting grooves formed in the die block, and the upper side and the lower side of the limiting grooves formed in the die block are arc-shaped protrusions. Preferably, the upper and lower both sides fixedly connected with of fixture block is the rubber piece that the arc set up, the arc protruding department in the spacing groove of seting up in rubber piece and the mould piece closely laminates. Preferably, the fixture block is rectangular, and the thickness of the limit groove formed in one side of the die block and one side of the die ring is larger than that of the fixture block.
