Description
Technical field
The utility model relates to a kind of shell product bus linearity hot school shape frock clamp.
Background technology
The problem on deformation of high strength steel cylinder light welding structure is the Focal point and difficult point that housing is manufactured always, for ensureing its accuracy of manufacture, usually needs control welding deformation and take postwelding school shape.Control welding deformation mainly to carry out welding again after " inner support is embraced outward " fixes to welding position by Special tooling clamp, but still can produce bus straightness error, namely the bus linearity of high strength steel cylinder light welding structure exceeds design error scope.
Certain shell product material is 2A14, diameter 2000mm, height 505mm, wall thickness 14mm, and housing is formed by upper casing section, lower part assembly welding, and after assembly welding completes, local also needs the Assembly parts such as soldering opening frame, reinforcing frame, cushion block.Because heat inputs a large amount of during welding, causes welding stress huge, cause welding deformation serious, part final appearance and size bus linearity (design load 1mm) is overproof.
Housing bus linearity is overproof, and follow-up housing cannot assemble and rivet, and final housing is scrapped, and will cause economic loss difficult to the appraisal, the manpower of at substantial, time cost.At present, the hot school shape technology of the bus linearity of shell product is not also had.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, a kind of shell product bus linearity hot school shape frock clamp and school shape technique thereof are provided, can solve shell product due to welding, machine add after the overproof problem of bus linearity, ensure the final appearance and size of each portion section, significantly improve housing, portion's section qualification rate, shorten the production of housing and issue handling cycle.
The purpose of this utility model is achieved through the following technical solutions: a kind of shell product bus linearity hot school shape frock clamp, it comprises two pieces of clamping plates 1, upper stretching screw 2, lower stretching screw 3, arc cushion block 4, strut 5 and briquetting 6, described two pieces of clamping plates 1 are symmetrical arranged, two upper stretching screw 2 horizontal symmetrical are removably fixed on the upside of clamping plate 1, the downside of upper stretching screw 2 is installed with the fixed head 7 of level, two lower stretching screw 3 horizontal symmetrical are removably fixed on the downside of clamping plate 1, the top of lower stretching screw 3 is fixed with arc cushion block 4, the top of described strut 5 is threaded portion, bottom is polished rod part, strut 5 passes fixed head 7 and passes through nut locking, the lower end of strut 5 is connected with briquetting 6.
Described arc cushion block 4 is concave structure low between the senior middle school of both sides.
The utility model has the following advantages: the utility model is by special strut, the school shape frock of the parts compositions such as screw rod, to housing bus linearity, overproof place supports and heats, then afterburning and hammering method elimination heating is taked, school shape stress, re-use the means of Slow cooling housing in atmosphere, the bus linearity at overproof for housing place is corrected to and meets the demands, this welds in space product portion section, belong to pioneering in production, there is key technology innovative value, shell product can be solved due to welding, the overproof problem of bus linearity after machine adds, ensure the final appearance and size of each portion section, significantly improve housing, portion's section qualification rate, shorten production and the issue handling cycle of housing.

In figure: 1-clamping plate, the upper stretching screw of 2-, stretching screw under 3-, 4-arc cushion block, 5-strut, 6-briquetting, 7-fixed head, 8-shell product, 9-heater.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As depicted in figs. 1 and 2, a kind of shell product bus linearity hot school shape frock clamp, it comprises two pieces of clamping plates, upper stretching screw, lower stretching screw, arc cushion block, strut and briquetting, described two pieces of clamping plates are symmetrical arranged, two upper tension screw stem waters are equalled symmetry and are removably fixed on the upside of clamping plate, the downside of upper stretching screw is installed with the fixed head of level, strain screw stem water under two and put down the symmetrical downside being removably fixed on clamping plate, the top of lower stretching screw is fixed with arc cushion block, the top of described strut is threaded portion, bottom is polished rod part, strut passes fixed head and passes through nut locking, the lower end of strut is connected with briquetting.
Described arc cushion block is concave structure low between the senior middle school of both sides.
The school shape technique of a kind of shell product bus linearity according to claim 1 hot school shape frock clamp is adopted to draw together following steps:
S1, clamping tooling fixture: find out the overproof place of shell product 8 bus linearity, and in the both sides at shell product 8 bus linearity overproof place, clamping plate 1 is installed, and be strained and fixed by upper stretching screw 2 and lower stretching screw 3, arc cushion block 4 is fixed between the overproof place of shell product 8 bus linearity and lower stretching screw 3, briquetting 6 by regulating the relative position between strut 5 and nut, and with the contact internal walls at the overproof place of shell product 8 bus linearity;
S2, heating: by heater, 9 pairs of overproof places of shell product 8 bus linearity heat, and heating temperature range is 150 DEG C ~ 180 DEG C, and is incubated;
S3, add force deformation: as shown in Figure 3, regulate the nut on strut 5 top, briquetting 6 is moved down, and to shell product 8 bus linearity, overproof place carries out slow reinforcing, and makes the overproof place of shell product 8 bus linearity externally protrude distortion 4mm ~ 5mm;
S4, release stress: with mallet centered by briquetting 6, diameter is carry out grouping within the scope of 200mm to knock, and percussion power is 80Kg ~ 120Kg, and often the group time of knocking is 2min ~ 3min, and two adjacent groups knocks interval 3.5h ~ 4.5h;
S5, cooling: close heater 9, with air cooling but;
S6, disassembling fixture: upper stretching screw 2 and lower stretching screw 3 are removed, shell product 8 is separated with frock clamp;
S7, leave standstill: shell product 8 is left standstill 22h ~ 26h;
S8, detection: to shell product 8 bus linearity, its linearity is measured by straightedge rule by overproof place, if linearity is not more than 1mm, then meets the requirements, if linearity is greater than 1mm, then repeat step S1 ~ S7.
