Description
Technical field
The utility model relates to a kind of pressure head and adjusts structure, and particularly a kind of pressure head centering of utilizing roller bed compacting knuckle steel plate is adjusted structure.
Background technology
Utilizing roller bed to carry out knuckle processing to the large scale steel plate that reaches tens meters, is a kind of processing method of expanding roller bed function, and it is feasible being proven the method.Add man-hour mould and supported by two lower rolls that be arranged in parallel, the one group of pressure head and the top roll that form a line are fixed, and processed steel plate is placed between pressure head and mould, and one group of pressure head is depressed under the drive of top roll, disposable large scale steel plate are processed to knuckle.At present, the following problem that this processing method has: 1, the centering of each pressure head center and mold center is adjusted as shown in Figure 6, pressure head 1 leans on manual measurement size adjustment entirely with the centering of the mould 3 groove 3-1 of bottom centre, the linearity of 6 pressure heads also needs to realize by artificial adjustment, exist measure error, the collimation error, need adjust operation repeatedly, consuming time, consumption power and adjust precision and be difficult to ensure; 2, the arcwall face that the upper surface of each pressure head is indent, because the arc contact surface of pressure head and top roll is less, in to steel plate knuckle process because of discontinuity occur sometimes pressure head on top roll surface slight phenomenon of sliding, thereby make the linearity on 6 pressure head summits occur error, the knuckle machining accuracy of impact to steel plate.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of and can realize fast and accurately the pressure head centering adjustment structure of utilizing roller bed compacting knuckle steel plate that the relative mould centering of pressure head is adjusted.
Problem described in the utility model is by realizing with following technical proposals:
A kind of pressure head centering of utilizing roller bed compacting knuckle steel plate is adjusted structure, it comprises top roll, mould, the lower roll that six pressure heads that form a line and pair of parallel arrange, mould is supported by two lower rolls, special feature is: described structure is also provided with the centering piece of adjusting for pressure head centering, centering piece is between mould and pressure head, centering piece bottom arranges boss, this boss coupling is inlaid in the central channel of mould, centering piece is provided with the V-shaped groove mating with pressure head cross section, V-shaped groove and mould centering, pressure head is inlaid in V-shaped groove, the relative die location of pressure head is determined afterwards and top roll is fixed.
The above-mentioned pressure head centering of utilizing roller bed compacting knuckle steel plate is adjusted structure, between described adjacent pressure head, is fixed by slot and inserted block, and wherein, slot and inserted block are separately fixed at the mutual approach end of two adjacent pressure heads, and inserted block coupling is inserted in slot.
The above-mentioned pressure head centering of utilizing roller bed compacting knuckle steel plate is adjusted structure, and two centering pieces are set between described every pressure head and mould.
When the utility model is suppressed knuckle steel plate for roller bed, the problem of pressure head centering adjustment difficulty is improved, and has designed a kind of pressure head centering and has adjusted structure.Described structure enclosed mass mould and pressure head, set up centering piece according to the cross sectional shape of mould and pressure head, centering piece bottom arranges boss, this boss coupling is inlaid in the central channel of mould, centering piece is also provided with the V-shaped groove mating with pressure head cross section, V-shaped groove and mould centering, and pressure head only need be seated in centering piece V-shaped groove can ensure pressure head and mould centering, then pressure head and top roll are fixed, realized the centering adjustment of one group of relative mould of pressure head.In addition, between adjacent pressure head, set up slot, inserted block fixture, avoided process to slide and produce straightness error because pressure head and top roll are slight.Adopt the utility model can greatly shorten pressure head centering and adjust the time, ensure that the centering of one group of pressure head is adjusted precision, increase substantially operating efficiency, and reduce the straightness error of product part, ensured processing precision of products.
