Abstract
A cold-rolling pipe mill for machining a rectangular pipe comprises an upper mill roll set and a lower mill roll set. The upper mill roll set comprises an upper mill roll and an upper mill roll shaft. The lower mill roll set comprises a lower mill roll and a lower mill roll shaft. The junction between the upper mill roll and the low mill roll forms a rectangular outline hole. A central spindle which is matched with a rectangular pipe hole is arranged in the outline hole. The two ends of upper mill roll shaft and the two ends of the lower mill roll shaft are respectively provided with synchronous gear transmission mechanisms and transverse cylinders, wherein the synchronous gear transmission mechanisms and the transverse cylinders are arranged in a staggered mode. A rack is provided with a crank link mechanism which can drive the rack to reciprocate. As the synchronous gear transmission mechanisms, the transverse cylinders and the crank link mechanism are adopted, wherein the two ends of upper mill roll shaft and the two ends of the lower mill roll shaft are respectively provided with the synchronous gear transmission mechanisms and the transverse cylinders, and the crank link mechanism can drive the rack to reciprocate; in the rolling process, a pipe billet is pushed forward by the utilization of the reciprocation of the rack, the upper mill roll and the lower mill roll rotate periodically by the utilization of the synchronous gear transmission mechanisms and the transverse cylinders, and meanwhile transverse rolling can be performed on the pipe billet between the two mill rolls through the transverse cylinders. Repeatedly, rolling of the whole pipe billet is completed.
Description
Technical field
The present invention relates to a kind of tubular object extruding equipment, particularly one kind process rectangle pipe material two roller cold pilger mills.
Background technology
It is using drawbench drawing, the shape of the production tube of cold drawn forming and chi that the cold working of traditional rectangular tubing produces
Very little, the wall thickness of especially pipe it tends to be difficult to reach higher accuracy class it is more difficult to meet the use of a part of specific user, this
Outward, for the rectangular tube that length-width ratio is relatively large, exist and cannot a drawing be molded, multi-pass draws to open up to pull out and also needs in the middle of increase
Heat treatment and operation of taking the lead, and then improve the deficiencies such as production cost.
Content of the invention
The technical problem to be solved is, for above-mentioned deficiency, provides one kind can improve rectangle pipe material
Machining accuracy, different size rectangle pipe material can be implemented with Continuous maching simultaneously and can effectively reduce the processing square of production cost
Shape tubing is with two roller cold pilger mills.
The technical scheme is that：A kind of processing rectangle pipe material cold pilger mill, including the frame being arranged on support,
It is arranged at the topping roll group in frame and bottom roll group, described topping roll group includes topping roll, topping roll axle, described bottom roll group
Including bottom roll, lower roller shaft, it is formed with rectangular profiled orifice in upper and lower roll joint portion, is provided with and rectangle in profile in the hole
The mandrel that pore is adapted, is respectively arranged with synchronous gear transport mechanism and traversing oil cylinder, wherein upper roller at upper and lower roll shaft two ends
Synchronous gear transport mechanism on axle is in interlaced arrangement with the synchronous gear transport mechanism on lower roller shaft, the traversing oil on upper roll shaft
Cylinder is in interlaced arrangement with the traversing oil cylinder on lower roller shaft, is provided with the crank that support body can be driven to do horizontal reciprocating movement even in frame
Linkage.
The present invention is due to employing the synchronous gear transport machine in dislocation arrangement being respectively provided with upper and lower roll shaft two ends
Structure, traversing oil cylinder mechanism and frame can be driven to do the toggle of horizontal reciprocating movement, during rolling, reciprocal using frame
Motion makes pipe push ahead, and using synchronous gear transport mechanism and traversing oil cylinder mechanism, makes upper and lower roll make periodically to turn
While dynamic, between two rollers, the horizontal calendering to pipe realized by traversing oil cylinder, go round and begin again, complete the rolling of whole pipe.
Brief description
The present invention is further detailed explanation below in conjunction with the accompanying drawings.
Fig. 1 is general structure schematic diagram of the present invention；
Fig. 2 is top and bottom rolls group mechanism principle figure of the present invention；
Fig. 3 is the schematic diagram after the relatively transverse movement of the upper and lower roll stacks of the present invention.
Specific embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of cold pilger mill of processing rectangle pipe material, including being arranged on support for the present invention
Frame 1, the topping roll group 2 being arranged in frame 1 and bottom roll group 3, described topping roll group 2 includes topping roll 21, topping roll axle
22, described bottom roll group includes bottom roll 31, lower roller shaft 32, is formed with rectangular profile in upper and lower roll 21,31 joint portion
Hole, is provided with, in profile in the hole, the mandrel 9 being adapted with rectangle pore, is respectively arranged with synchronous gear at upper and lower roll shaft 22,32 two ends
Wheel drive mechanism 4 and traversing oil cylinder 5, wherein go up the synchronous gear on synchronous gear transport mechanism 4 and the lower roller shaft 32 on roll shaft 22
Wheel drive mechanism 4 is in interlaced arrangement, and the traversing oil cylinder 5 on upper roll shaft 22 is in interlaced arrangement with the traversing oil cylinder 5 on lower roller shaft 32,
The toggle 6 that support body can be driven to do horizontal reciprocating movement is provided with frame 1.
Above-mentioned synchronous gear transport mechanism 4 includes synchromesh gear 41, tooth bar 42, and described synchromesh gear 41, tooth bar 42 are arranged
In frame 1.Above-mentioned toggle 6 includes crank 61, connecting rod 62, and one end of described connecting rod 62 is connected with frame 1.
The further concrete structure of the present invention is：Described toggle, crank is arranged at the frame of frame one end
Near rail, crank is connected with connecting rod one end, and connecting rod is driven with frame phase and connects, and crank does continuous rotary motion, drivening rod around center
Frame is made to do horizontal reciprocating movement, upper and lower roll mandrel is arranged in frame, the two ends of its roll mandrel are laid with dislocation together respectively
Step gear mechanism and horizontal oil cylinder, above-mentioned synchromesh gear mechanism is made up of gear, tooth bar, and described gear, tooth bar may be provided at one
In fixed base, for ensureing the uniformity of top and bottom rolls motion, the number of teeth of said gear is identical.
The whole work process of the present invention is realized in：When work housing is made back and forth under toggle drive
During motion, the corresponding pipe of upper and lower roll being installed in frame forms flow of metal area in roller groove, in deformed area, pipe
The inside of base axially need to fix the plug that a profile is adapted with required processing rectangle pipe orifice, whenever work housing moves to
During two rapid extreme positions, pipe and plug just rotate 90 °, and meanwhile, pipe is advanced to certain feed, meanwhile,
Upper and lower roll, by the driving of horizontal oil cylinder, is implemented the calendering to pipe, is so gone round and begun again, complete the rolling of whole pipe.
