Abstract
The utility model relates to the technical field of centralizer manufacturing and particularly relates to a secondary bending device for a hoop of a centralizer. The device comprises a first upper die, a first lower die matched with the first upper die, a second upper die and a second lower die matched with the second upper die. The first upper die is composed of a first pressing block and a first retaining block. A chamfer is arranged on one side of the first pressing block, the first retaining block is arranged above the chamfer and fixed with the first pressing block through a bolt, the second upper die is composed of a second pressing block and a second retaining block which are fixed on an upper die holder, and a chamfer is arranged on the second pressing block. The first lower die and the second lower die are arranged on the two sides of a lower die holder in a mirror mode. The device is simple in structure, the upper die is designed in a split structure, the bending portions of a steel plate can bend towards the chamfer directions, and the front ends of the steel plate bending portions can be snapped on the snapping blocks, so that bending angles can be controlled accurately, and the forming accuracy is improved.
Description
Technical field
The utility model relates to the manufacturing technology field of centralizer, relates 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 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, is 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 are all better than 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, is conducive to reduce reciprocating friction wearing and tearing and reduces pumping unit load; Moderate hardness, is conducive to reduce the wearing and tearing to oil pumping body and the oil pumping body of rod.
At present, need to pass through punching, bending, volume and enclose several steps when manufacturing the hoop of centralizer, 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.
Utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of centralizer hoop secondary apparatus for bending is provided, and improves bending precision.
The utility model for achieving the above object, by the following technical solutions:
A centralizer hoop secondary apparatus for bending, is characterized in that: comprise the first patrix, the first counterdie coordinating with the first patrix, the second patrix, the second counterdie coordinating 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; The steel plate that described die shoe is provided with for a upper procedure is completed 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 being fixed on upper bolster.
The beneficial effects of the utility model are: the utility model is simple in structure, because patrix adopts 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model light plate;
Fig. 3 is the hoop structure schematic diagram after moulding in the utility model;
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 utility model in detail.As shown in Figure 1 to Figure 3, a kind of centralizer hoop secondary apparatus for bending, comprises the first patrix 1, the first counterdie 2 coordinating with the first patrix, the second patrix 3, the second counterdie 4 coordinating 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; The steel plate that described die shoe is provided with for a upper procedure is completed 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 being 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 merit stamping machine, stamping machine drives the first patrix and the second patrix to move down, 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 merge, the front end of steel plate is spacing by the first block and the second block, has guaranteed the accuracy of bending.
The utility model is simple in structure, and because patrix adopts 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 preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
