Description
Technical field
The utility model is related to a kind of small-radius arc shaped device, mainly for the manufacture of industry Small Radius circular arc into
Type, either steel plate or other sheet materials, during small-radius arc is molded, because shaping is difficult, size bad control,
Defect rate is very high always, and the product of processing does not reach customer requirement, by the use of this shaped device, greatly improves the conjunction of product
Lattice rate, it is ensured that product quality, efficiently solves the problem of three roll shaft veneer reeling machines can not roll small-radius arc, and sheet material is suppressed
Two ends are without remained straight edge after shaping.
Background technology
At this stage, various forms of veneer reeling machines are a lot, but can not all roll small-radius arc, and plate compression moulding mostly
The straight flange of certain length is left at two ends afterwards, and Forming Quality is not fine, and particularly small-radius arc is used extensively in manufacturing industry,
Highway in China, railway and urban construction are just in progress like a raging fire, and various cylinders, cylinder template demand constantly increase, circle
The appearance requirement of arc also more and more higher, and in the processing and making process of template, the shaping of circular arc is not up to standard, has a strong impact on
The presentation quality of template and construction period.In the past to such issues that be all by beating, fire is roasting reaches the purpose of shaping, and uses this
A little methods are it cannot be guaranteed that product size, while taking a lot of work very much, to take material, efficiency low.
Utility model content
The utility model overcomes existing shortcoming in the art there is provided a kind of small-radius arc shaped device, overcomes
Existing three roll shafts veneer reeling machine can not roll the technical problem of small-radius arc, and the present apparatus is simple in construction, easy to operate, make
With safety, the rapid shaping of small-radius arc is realized, labor strength is greatly reduced.
The technical solution of the utility model is：A kind of small-radius arc shaped device, including operating platform and it is arranged on behaviour
Make the column assembly on platform, rack beam assembly is welded with column assembly, hydraulic pressure is fixed with rack beam assembly
Oil cylinder, hydraulic jack is connected with upper roll shaft；Be connected with left and right regulation screw mandrel on column assembly, left and right regulation screw mandrel respectively with
Left and right lower roller shaft connection.
Further, the column assembly is welded and fixed on the operational platform.
Further, the left and right regulation screw mandrel is connected by bearing pin with column assembly respectively.
Further, fixed oil cylinder crossbeam assembly is welded with column assembly, the hydraulic jack passes through fixed oil cylinder
Crossbeam assembly is positioned and fixed.
Further, the left and right lower roller bearing is free to rotate.
Further, the hydraulic jack includes tri- oil cylinders of a, b, c, and wherein a, c is operating cylinder, and b is auxiliary cylinder.
Compared with prior art, the utility model has the advantages that：Efficiently solve three roll shaft veneer reeling machines can not roll it is small
Two ends solve small-radius arc shaping hardly possible and shaping radian are not marked without remained straight edge after radius arc, and plate compression moulding
Accurate key technical problem, this shaped device is compressing efficiently, quick, cost is low, improves small-radius arc Workpiece shaping
Circular arc quality；Improve the presentation quality of processing workpiece；The scale error of circular arc workses is also reduced simultaneously, is reduced secondary
Product rate, improves labor productivity.
Brief description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein：
Fig. 1 is the front view of this shaped device structure；
Fig. 2 is the side view of this shaped device structure；
Fig. 3 is the side view before this shaped device pressurizes to workpiece；
Fig. 4 is the side view after this shaped device pressurizes to workpiece.
Embodiment
A kind of small-radius arc shaped device, as depicted in figs. 1 and 2, including：Pumping plant 1, upper roll shaft 2（Can as needed more
Change）, left and right lower roller shaft 3, hydraulic jack 4, left and right lower roller shaft regulation screw mandrel 5, column assembly 6, rack beam assembly 7, fixing oil
Cylinder crossbeam assembly 8, operating platform 9 etc., wherein：
Operating platform 9 is placed on level ground, and column assembly 6 is weldingly fixed on operating platform 9, while rack beam
Assembly 7 and fixed oil cylinder crossbeam assembly 8 are all welded on column assembly 6, and lower roller shaft regulation screw mandrel 5 in left and right passes through bearing pin and column
Assembly 6 is connected, and hydraulic jack 4 is fixed on rack beam assembly 7, and hydraulic jack 4 is by the fixation that is fixed on column assembly 6
Oil cylinder crossbeam assembly 8 is positioned, fixed, and upper roll shaft 2 is connected with hydraulic jack 4, and upper roll shaft 2 can be according to different radian size requirements
The roll shaft of different sizes is changed, left and right lower roller shaft 3 is connected with left and right lower roller shaft regulation screw mandrel 5, can adjusted as requested respectively
Save the distance between left and right lower roller shaft 3；Roller bearing 3 is free to rotate under left and right, thus reduce it is compressing during resistance；Really
The size of roll shaft 2 is set, the spacing of left and right lower roller shaft 3 is regulated, puts well after workpiece, it is many on pumping plant 1 by operating
Road valve makes the work of hydraulic jack 4 produce lower pressure, and lower pressure is delivered on roll shaft 2, then acted on workpiece, workpiece is produced
Raw pressure, reaching makes the purpose of Workpiece shaping.
Operation principle of the present utility model is：Pushing workpiece by hydraulic jack and reach makes the purpose of Workpiece shaping, specifically
Operating procedure is as follows：
Step 1: replacing with roll shaft according to arc radius size；
Step 2: according to circular arc size by adjust screw mandrel adjust left and right lower roller shaft between spacing；
Step 3: workpiece is placed on shaped device and fixed, as shown in Figure 3；
Step 4: hydraulic jack works so that upper roll shaft is pushed, and reaches Workpiece shaping, as shown in Figure 4；
Step 5: hydraulic jack is retracted so that upper roll shaft unclamps, and removes the workpiece of shaping.
In shaped device, the spacing between the lower roller shaft of left and right is should be noted, has both ensured that workpiece does not fall down, ensures workpiece energy again
Enough reach shaping standard；Oil cylinder is work package in shaped device, and a, c hydraulic jack are main work package, and b is auxiliary cylinder.
