Abstract
The utility model provides a rolling tube movement rod head. When a movement rod advances, the process that the movement rod contacts a pre-penetrating rack and the tail part of a hair tube is smoother, thereby reducing the abrasion deformation at the end of the movement rod, and reducing the rolling cost. The rolling tube movement rod head comprises the movement rod, and is characterized in that the conical degree of the cone body at the head end of the movement rod is 30 degrees, and the height of the cone body at the head end of the movement rod is 150mm.
Description
Technical field
The utility model relates to employed tandem mill parts in the hot rolled seamless steel tube production, is specially the mandrel mill head.
Background technology
Plug is tandem mill when rolling, one of employed important warp tool, and its effect is to constitute the blind bore type with the tandem rolling roller, makes hollow billet when rolling, limit metal deformation, the hollow forging of technological requirement is satisfied in acquisition.The form of the off-line feed-through rod that my company adopts at present: hollow billet is transported to material poking fork from the punch backstage through revoliving arm; Be allocated to the plug prewire through material poking fork then; Plug on the prewire is halted when arriving assigned address by the insertion hollow billet that advances under the chain drive at this moment.Plug and hollow billet are transported on the roll line of tandem mill foreground through revoliving arm together then, and the plug hollow billet backing roll on the roll line rises and supports hollow billet and plug simultaneously, and this moment, the plug caudal peduncle got into the plug clamp sleeve of restraint tooth bar.Hollow billet retaining fork rises afterwards, and top pinch roll falls, and restraint rack drives plug begins secondary and inserts, and when plug was inserted into desired location, hollow billet retaining fork descended, and hollow billet and plug are sent into tandem mill together by pinch roll and be rolled.
When plug advances under the drive of wearing chain in advance; Because head end collides with the shelf of wearing stand in advance easily, when the plug head end begins to insert simultaneously, a collision is arranged with the hollow billet afterbody; Such collision can cause the nearly plug end abrasion deformation of wearing stand in advance; Make the plug scratch simultaneously, reduce the service life of plug, thereby increased production cost.
Summary of the invention
To the problems referred to above, the utility model provides the mandrel mill head, and plug is when advancing, and is milder when wearing stand and hollow billet afterbody in advance and contact, thereby has reduced the abrasion deformation of plug end, has practiced thrift rolling cost.
The technical scheme of the utility model is: it comprises plug, it is characterized in that: said plug head end cone taper is 30 °, and the height of said plug head end cone is 150mm.
After the utility model adopts said structure, milder when wearing stand and hollow billet afterbody in advance and contact in the process of advancing of plug when wearing in advance, can fierceness not collide, thereby avoided damage stand and plug, thereby practiced thrift rolling cost.
Description of drawings
Fig. 1 is the sketch map of the utility model plug.
The specific embodiment
See Fig. 1, the utility model comprises plug 1, and plug head end cone taper is 30 °, and A is half angle of plug head end cone taper among Fig. 1, and the height H of plug head end cone is 150mm.The utility model is the tapering that changes the plug head end, guaranteeing that the plug head length can satisfy under the prerequisite of rolling demand, 40 ° of plug head end angles is decreased to 30 °, plug head end length is added by 100mm grow to 150mm simultaneously at present.Thereby plug in use, and is milder when wearing stand and hollow billet afterbody in advance and contact, thereby reduced the abrasion deformation of plug end, prolonged the service life of plug, practiced thrift rolling cost.
