The structural disadvantages of known cold pilger mill is because can't follow the tracks of by the time steel billet breaking joint in the deformed area, be arranged to low speed rolling, so tube rolling to be of low quality.Reason is, the steel billet chuck is as long as one pass by and equal the distance of next steel billet length, the cold pilger mill material loading again that just stops, and the size of this distance changes.
Because the operation of rolling is to carry out on the basis of low deformation velocity, above disadvantages affect the quality and the output of tube rolling.
Summary of the invention
Purpose of the present invention will provide a kind of cold pilger mill exactly, and it can be followed the tracks of by the time steel billet breaking joint in the deformed area, with the steel billet of the rolling all lengths of speed of the best, thereby improves the tube rolling quality, improves output.
Purpose of the present invention is finished by following method, according to the present invention, dispose work housing and the feed screw mandrel formula aggregate feeder units that band drives, and aggregate feeder units links to each other with work housing by guider, nut on the steel billet chuck and feed screw mandrel interact, before and after on the basis of this cold pilger mill that links to each other in twos by telescopic tractor of carriage, sensor installation on first front rack in front, make its can the steel billet front end by the time send signal, the locator of the sensor is installed, and the steel billet clamper is installed in the front of first front rack in front on guider.
The cold pilger mill of this structure can be followed the tracks of to the breaking joint between former and later two pipe end faces and advancing of deformed area, is rolled with optimum speed, thereby improves the tube rolling quality, improves the output of cold pilger mill.
Achieve the above object, a sensor is installed on first front rack in front, when the sensor sensing district appears in the front end of the steel billet that moves forward by the steel billet chuck, send signal to control system immediately, the steel billet chuck is stopped, steel billet is stopped, reach minimum with the breaking joint size between the steel billet end face that guarantees previous steel billet and will adorn.Several locators are installed on guider, to avoid when scalable tractor skid conditions changes, making carriage occur moving voluntarily, and the sensor appearance that causes thus being installed on first front rack of front is mobile voluntarily, thereby guarantees the stable of the operation of rolling.
Sensor error starts when steel billet chuck and carriage return initial position in order to avoid, the present invention first front rack front in front installs clamper, also can avoid simultaneously short steel billet to move backward uncontrollably, thereby guarantee that short steel billet also can be rolled preferably.
Description of drawings
Figure 1 shows that cold pilger mill begins the schematic diagram when rolling, dotted line is depicted as carriage, steel billet chuck and top steel billet among the figure;
Figure 2 shows that the steel billet front end is by the schematic diagram of that time of sensor in the cold pilger mill operation of rolling.
The specific embodiment
Below in conjunction with instantiation and accompanying drawing thereof invention is described:
Cold pilger mill includes the work housing 1 that band drives, the aggregate feeder units 2 that has feed screw mandrel 3, aggregate feeder units 2 links to each other with work housing 1 by guider 4, nut 6 on the steel billet chuck 5 interacts with feed screw mandrel 3, and front rack 7 and tail-bracket 8 pairs of feed screw mandrels, core bar and steel billets play a supportive role.Front rack 7 links to each other by tractor 9 in twos with tail-bracket 8.Carriage is connected in the right tractor 9 one be sleeved on another the inside, and can stretch out and indentation.
A sensor 10 is installed on the front rack 7, so as the steel billet front end by the time can send signal, be furnished with the locator 11 of several these sensors on the guider 4.The front of front rack 7 is equipped with steel billet clamper 12.Carriage 7,8 and steel billet chuck 5 move gently along guider 4.When the skid conditions of scalable tractor 9 changes, do not touch at carriage under the situation of steel billet chuck, just might take place to move voluntarily, this will cause occurring in the work wild effect.Locator 11 produces and occurs for fear of this phenomenon, it can pin last tail-bracket 8, afterwards also pinning by tractor 9 first front racks of front coupled, that sensor 10 is housed above it, carriage is fixed on the position that a strictness decides, up to sensor 10 send to load steel billet front end face by and the signal that carries out release.The structure of locator can be various, as: spring, fluid pressure type, pneumatic type or other forms, but must guarantee that steel billet chuck 5 can following in working order straightway moving.
