Abstract
The invention relates to the technical field of production of centralizers, in particular to a secondary bending device for centralizer hoops. The secondary bending device comprises a first upper die, a first lower die, a second upper die, a second lower die, wherein the first lower die matches with the first upper die and the second lower die matches with the second upper die. The first upper die consists of a first pressure block and a first stopper. One side of the first pressure block is chamfered. The first stopper disposed above the chamfer is fixed to the first pressure block through bolts. The second upper die consists of a second pressure block and a second stopper. The second pressure block and the second stopper are fixed to an upper die base. The second pressure block is chamfered. The first lower die and the second lower die are disposed on two sides of the lower die base by mirror symmetry. The secondary bending device is in the split structural design, so that a bent part of a steel plate can be bent along the chamfers; the front end of the bent part of the steel plate is likely to be clamped to the stoppers, so that bending angle can be controlled accurately and forming accuracy is higher.
Description
Technical field
The present invention relates to the manufacturing technology field of centralizer, relate in particular to a kind of centralizer hoop secondary apparatus for bending.
Background technology
Centralizer belongs to cementing tool, and it manufactures simple, and structure is attractive in appearance, firm and durable, and uprighting force is large, has overcome the deficiency that sealing-off easily occurs former welded type centralizer, is a kind of centralizer that can guarantee the well drilling and cementing quality.Centralizer is of a great variety, by structure, can be divided into roller type, slide block type, automatic reverse formula etc.The centralizer of different structure and material, be applicable to the oil well of dissimilar eccentric wear.Using centralizer eccentric wear-proof process key technology is position, spacing and the quantity that centralizer is installed.Oil pumping rod centering device resistance to wears, shock resistance, anticorrosive, low temperature resistant, self lubricity, non-absorbency all are better than the conventional nylon centralizer greatly, overcome the easy water absorption and swelling of nylon, hydrolysis, black brittleness is large, frangible, frictional resistance is large shortcoming, due to extremely excellent pliability, impact-absorbing energy characteristic, bar, the pipe that can weaken in reciprocating motion clash into; Extremely low coefficient of friction, be conducive to reduce the reciprocating friction wearing and tearing and reduce pumping unit load; Moderate hardness, be conducive to reduce the wearing and tearing to oil pumping body and the oil pumping body of rod.
At present, when manufacturing the hoop of centralizer, need to pass through punching, bending, the several steps of volume circle, in prior art, the bender at steel plate two ends be done mainly on stamping machine, to carry out, bending precision is lower, and bending speed is slow.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned technology, and a kind of centralizer hoop secondary apparatus for bending is provided, improve bending precision.
The present invention for achieving the above object, by the following technical solutions:
A kind of centralizer hoop secondary apparatus for bending is characterized in that: comprise the first patrix, the first counterdie that coordinates with the first patrix, the second patrix, the second counterdie that coordinates with the second patrix; Described the first patrix consists of the first briquetting and the first block, one side of described the first briquetting is with chamfering, described the first block is arranged on the top of chamfering and fixes by bolt and described the first briquetting, described the second patrix consists of the second briquetting and the second block, described the second briquetting and the second block are fixed on upper bolster, on the second briquetting with chamfering; Described the first counterdie and the second counterdie are the both sides that mirror image is arranged on die shoe; Described die shoe is provided with for the steel plate that a upper procedure is completed and is pushed into the cylinder on the first counterdie and the second counterdie, on the piston rod of cylinder, is fixed with push pedal.
Preferably, a side of described the first patrix is provided with the pneumatic jack bar that is fixed on upper bolster.
The invention has the beneficial effects as follows: the present invention is simple in structure, because patrix adopts the split-type structural design, the bending part branch of steel plate is along the bending of chamfering direction, and the front end of steel plate bending part can be stuck on block simultaneously, can control accurately bending angle, improve the accuracy of moulding.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of light plate of the present invention;
Fig. 3 is the hoop structure schematic diagram after moulding in the present invention;
In figure: 1, the first patrix; 2, the first counterdie; 3, the second patrix; 4, the second counterdie; 5, the first briquetting; 6, the first block; 7, chamfering; 8, bolt; 9, the second briquetting; 10, the second block; 11, chamfering; 12, cylinder; 13, pneumatic jack bar; 14, steel plate.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, describe the specific embodiment of the present invention in detail.As shown in Figure 1 to Figure 3, a kind of centralizer hoop secondary apparatus for bending, comprise the first patrix 1, the first counterdie 2 that coordinates with the first patrix, the second patrix 3, the second counterdie 4 that coordinates with the second patrix; Described the first patrix consists of the first briquetting 5 and the first block 6, one side of described the first briquetting is with chamfering 7, described the first block is arranged on the top of chamfering and fixes by bolt 8 and described the first briquetting, described the second patrix consists of the second briquetting 9 and the second block 10, described the second briquetting and the second block are fixed on upper bolster, on the second briquetting with chamfering 11; Described the first counterdie and the second counterdie are the both sides that mirror image is arranged on die shoe; Described die shoe is provided with for the steel plate that a upper procedure is completed and is pushed into the cylinder 12 on the first counterdie and the second counterdie, on the piston rod of cylinder, is fixed with push pedal, and a side of described the first patrix is provided with the pneumatic jack bar 13 that is fixed on upper bolster.
During use, the steel plate 14 that piston rod on cylinder first completes a upper procedure is pushed on the first counterdie and the second counterdie, open the merit stamping machine, stamping machine drives the first patrix and the second patrix moves down, the steel plate front end is along the chamfering direction bending on the first briquetting and the second briquetting, after two upper die and lower die merged, the front end of steel plate was spacing by the first block and the second block, has guaranteed the accuracy of bending.
The present invention is simple in structure, and because patrix adopts the split-type structural design, the bending part branch of steel plate is along the bending of chamfering direction, and the front end of steel plate bending part can be stuck on block simultaneously, can control accurately bending angle, improves the accuracy of moulding.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
