Description
Technical field
The present invention relates to a kind of metal pipe material cold working equipment, particularly a kind of processing square-outside and round-inside tubing cold rolled tube
Machine.
Background technology
At present, the cold working of metal pipe material produces and mostly uses drawbench to draw, this manufacture method finished product to cold drawn forming
The wall thickness of the shape and size of pipe especially pipe, it tends to be difficult to reach higher accuracy class, and for having outside particular demands
The tubing manufacture of side's inner circle, also exist especially cannot disposably drawing molding, be both needed to employing multiple tracks drawing and intermediate heat-treatment, beat
First-class operation can realize, and has the most both caused complex process, makes again manufacturing cost improve, it is difficult to meet the demand of specific user.
Summary of the invention
The technical problem to be solved is to provide a kind of has the product that seriality is processed and formed at one time and produces
The square-outside and round-inside tubing cold pilger mill that precision is higher.
The technical scheme is that a kind of processing square-outside and round-inside tubing cold pilger mill, including the work being arranged on support
Make frame and the roller assembly being arranged in work housing, roller seat that described roller assembly includes being equipped with in frame in dynamic,
Topping roll group and bottom roll group, described topping roll group includes topping roll, upper roll shaft, and bottom roll group includes bottom roll group, lower roller shaft,
Roll surface in upper and lower roll joint portion is provided with the linear profile hole being square, and is provided with suitable with inner hole of square in profiled orifice
Mandrel, is respectively equipped with the synchronous gear transport mechanism in interlaced arrangement in upper and lower roll shaft one end, is provided with in one end of work housing
Toggle, the other end at work housing is provided with double rocker mechanism.
Due to the fact that and have employed the synchronous gear transport mechanism being respectively provided with in upper and lower roll shaft one end, be combined in working machine
Toggle that frame and roller seat are arranged and double rocker mechanism, during rolling, utilize toggle to drive work housing to make past
Multiple motion makes pipe push ahead, and utilizes synchronous gear transport mechanism to cooperate with double rocker mechanism, makes top and bottom rolls make week
While phase property rotates, realize the horizontal calendering to pipe by mobile roller seat between two rollers, so go round and begin again, complete whole pipe
The rolling of base.
Accompanying drawing explanation
The present invention is further detailed explanation below in conjunction with the accompanying drawings.
Fig. 1 is population structure schematic diagram of the present invention；
Fig. 2 is the simple mechanism schematic diagram of top and bottom rolls group of the present invention.
Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of processing square-outside and round-inside tubing cold pilger mill, including being arranged on support for the present invention
Work housing 3 and the roller assembly 4 that is arranged in work housing 3, described roller assembly 4 includes being equipped with in frame in dynamic
Roller seat 45, topping roll group and bottom roll group in 3, described topping roll group includes topping roll 41, upper roll shaft 42, bottom roll group bag
Including bottom roll 43, lower roller shaft 44, the roll surface in upper and lower roll 41,43 joint portion is provided with the linear profile hole being square, at wheel
Being provided with the mandrel 6 suitable with inner hole of square in wide hole, be respectively equipped with in interlaced arrangement in upper and lower roll shaft 42,44 one end is same
Step gear drive 46, is provided with toggle 1 in one end of work housing 3, and the other end at work housing 3 is provided with double
Endplay device 2.
Above-mentioned synchronous gear transport mechanism 46 includes synchromesh gear 46a, tooth bar 46b, described synchromesh gear 46a, tooth bar 46b
It is arranged in work housing 3.Above-mentioned toggle 1 includes crank 11, connecting rod 12, one end of described connecting rod 12 and work
Frame 3 is connected, and above-mentioned double rocker mechanism 2 includes fork 21, upper rocking bar 22, lower rocking bar 23, wherein: above-mentioned upper rocking bar 22
One end is connected with work housing；One end of above-mentioned lower rocking bar 23 is connected with roller seat 45, and the other end is connected with fork 21；
Slide block 24 it is provided with between rocking bar 22 and fork 21 on above-mentioned.
The structure further of the present invention is: described toggle, double rocker mechanism are separately positioned on support, its
In: crank is connected with connecting rod, and connecting rod is connected with work housing, and one end of above-mentioned upper rocking bar is connected with work housing, lower rocking bar
One end be connected with roller seat, the other end is connected with fork, is provided with slide block on above-mentioned between rocking bar and rocking bar, power make
Under with, crank makees continuous rotary motion around center, and drivening rod makes work housing do horizontal reciprocating movement, the most also drives
Double rocker mechanism swings, so that work housing produces laterally opposed motion with roller seat, above-mentioned synchronous gear transport mechanism is arranged on
In work housing, for ensureing the concordance of top and bottom rolls motion, the number of teeth of said gear is identical.
The whole work process of the present invention is achieved in that when work housing makees reciprocal fortune under toggle drives
Dynamic, simultaneously when synchronous gear transport mechanism and double rocker mechanism work, the corresponding pipe of the top and bottom rolls that is installed in frame exists
