Abstract
The utility model discloses a copper and copper alloy tube stock double-roll rolling device which comprises a loading system and a discharging system, and is characterized in that a double-roll rolling machine is arranged between the loading system and the discharging system, and one feed end of the double-roll rolling machine is provided with a pipe billet clamping and feeding device; and the double-roll rolling machine comprises an upper roll, a lower roll and a supporting roll. In the utility model, the supporting roll is configured so that the device can roll alloy with large resistance to deformation and can realize large feed-in quantity rolling, the rolling system can not cause unstable running, and the rolling product is stable in quality.
Description
Technical field
The utility model relates to rolling device, especially relates to a kind of copper and copper-alloy pipe-material two rolling system devices.
Background technology
Existing two rolling system devices are to adopt motor to drive reductor by belt, and reductor drives rolling system work by toggle.Roll is unworthy of backing roll, and transmission system also is unworthy of bascule.The problem that exists is that the transmission efficiency of milling train is low, energy consumption is high.Because roll is unworthy of backing roll, when the bigger alloy of rolling deformation drag or rolling feed were big slightly, roll system tended to occur fluctuation of service, the rolled product degradation.Defectives such as product surface is easy to occur chewing, section irregularity, overlap.Particularly dynamical system is unworthy of bascule, and there is very big impact load in roll when doing reciprocal rolling motion.Structural strength to rolling system proposes very high requirement, and the energy utilization efficiency of the operation of rolling is low, and the milling train cabinet also is difficult for realizing macrocyclic effective sealing, is prone to technological lubrication liquid and reveals.Roll back and forth impacts another big shortcoming, and milling train reciprocating motion speed is subjected to the influence of roll system motional inertia, and mill speed is very restricted, and the speed of service of domestic general milling train is about 50 times/minute, and production efficiency can't effectively improve.
The utility model content
The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, and a kind of copper and copper-alloy pipe-material two rolling system devices are provided, and this device adopts ELEMENTARY INTRODUCTION TO NON technology production high accuracy copper and copper alloy seamless pipe material under cold state.
Above-mentioned purpose realizes by following proposal:
A kind of copper and copper-alloy pipe-material two rolling system devices, it comprises feeding system and discharge system, it is characterized in that, between described feeding system and discharge system, be provided with two roller roll mills, pipe chucking feeder is installed at charging one end of described two roller roll mills; Described two roller roll mills comprise topping roll, bottom roll and backing roll, the roll surface of described topping roll, the bottom roll formation pass that is close together, top backing up roll be positioned at topping roll above, the roll surface of described top backing up roll and the upper face of described topping roll are close together, described lower support roller be positioned at bottom roll below, the roll surface of described lower support roller and the lower surface of described bottom roll are close together.
The beneficial effects of the utility model: roll of the present utility model is furnished with backing roll, the transmission efficiency of milling train is significantly improved, required power reduces, mill speed improves.The benefit that roll is joined backing roll is, can the big alloy of rolling deformation drag, can realize that also big feed is rolling, and roll system fluctuation of service can not occur, the rolled product steady quality.Dynamical system balancing device, roll have been eliminated the negative effect of impact load when doing reciprocal rolling motion, the energy utilization efficiency of the operation of rolling improves, and mill speed and production efficiency effectively improve.

Fig. 1 is a structural representation of the present utility model.
The specific embodiment
A kind of copper and copper-alloy pipe-material two rolling system devices, it comprises feeding system 2a and discharge system 2c, is provided with two roller roll mills between feeding system 2a and discharge system 2c, at charging one end of two roller roll mills pipe chucking feeder 5 is installed; Two roller roll mills comprise topping roll 1, bottom roll 2, upper support roller 3 and lower support roller 4.The roll surface of upper and lower roll 1, the 2 formation pass that is close together, top backing up roll 3 be positioned at topping roll 1 above, the upper face of the roll surface of top backing up roll 3 and topping roll 1 is close together, and topping roll is played a supportive role, and prevents that topping roll from taking place to be out of shape around song because of insufficient rigidity in the operation of rolling.Lower support roller 4 be positioned at bottom roll 2 below, the lower surface of the roll surface of lower support roller 4 and bottom roll 2 is close together, and bottom roll 2 is played a supportive role, and prevents that bottom roll 2 from taking place to be out of shape around song because of insufficient rigidity in the operation of rolling.
