Abstract
The invention belongs to flexible manufacturing methods for molded surfaces of composite forming molds and relates to a flexible manufacturing technique for a molded surface. The flexible manufacturing technique for the molded surface is particularly suitable for the occasion that the radian of the molded surface is simplex, and the molded surface pressing efficiency can be improved by the adoption of the flexible manufacturing technique. The flexible manufacturing technique comprises the steps that firstly a movable platform completes the position adjustment, in the X direction, of hydraulic cylinders through a lead screw, a nut and a clamping block; secondly, the movable platform completes the position adjustment, in the Y direction, of the hydraulic cylinders through a clamping plate and a position hole in a rotating piece; and finally, the rotating piece moves back and forth in a groove of the movable platform through a hydraulic system, so that forward rotation by a 50-degree sector and reverse rotation by a 50-degree sector of the hydraulic cylinders in the X plane and the Z plane are completed, an X-direction, Y-direction and Z-direction three-dimensional mechanism is formed to make the axes of the hydraulic cylinders be perpendicular to all positions of the molded surface all the time, all the hydraulic cylinders press the molded surface in a certain sequence so as to make a steel plate of the molded surface be attached to a ribbed plate, the portion where each hydraulic cylinder is attached is welded immediately, and the same operation is conducted on an area beside till pressing of the whole molded surface is completed after all the hydraulic cylinders press an area of the molded surface and welding and fixing of the area are completed.
Description
Technical field
The invention belongs to manufacturing process field.
Background technology
In the manufacture process in the composite material forming model face of present stage, especially process aspect is relatively backward, or adopt and whole profile is divided into polylith low profile, every piece of low profile again with 50 tons of forcing press die moulds and again and again compare with plaster mold laminating until meet profile requires, finally each low profile splice on plaster mold, welding fabrication, there is much deficiencies in manufacture method:
1. entirely cause that surface contour error there will be more greatly repeated multiple times compacting phenomenon again with workman's naked eyes and experience without reference to thing when manually suppressing low profile with forcing press, waste time and energy and in handling process, there is potential safety hazard.
2. with the process that reclines of plaster mold in once the undesirable meeting of the precision of plaster mold causes the profile bigger error of undesirable generation.
3. producing a plurality of weld seam during the molding of sixty-four dollar question low profile assembly welding, the easy temperature distortion of the excessive mould of welding capacity and weld are easy to gas leak phenomenon.
The invention provides a kind of when not needing bigger investment, use multiple hydraulic cylinder that profile carries out flexible compacting thus global formation makes profile compacting be easier to, improve production efficiency, prevent gas leakage.
Summary of the invention
It is an object of the invention to: improve the compacting efficiency of composite material shaping mould profile, reduce manpower and materials, reduce the welding capacity of profile, it is prevented that profile is leaked gas.
The technical scheme is that the present invention includes mobile platform and tumbler, mobile platform and tumbler adopt the connected mode of groove semicolumn to connect, tumbler can carry out fan-shaped rotation in the groove of mobile platform, stamped fluid cylinder pressure is installed on tumbler by groove and keeper, and this stamped fluid cylinder pressure can join at the enterprising luggage in multiple positions of tumbler, the rotation of tumbler is driven by rotational hydraulic cylinder.
This method has steps of:
(1) the gusset framework of composite material forming mould is carried out digital control processing by die face, and as the laminating object of reference that profile is accurately suppressed.
(2) by calculating the deformation force of δ=20mm steel plate, it is preferable that steel plate materials is 20#, to determine the specification of hydraulic cylinder, it is preferred between 40t-60t
(3) design the mobile platform, tumbler, clamp and the fixture block that are driven by hydraulic system, enable hydraulic cylinder to be perpendicular to the profile of various radian in space, and compacting place is positioned accurately;
(4) on the boss of tumbler, bore hole, location, be used for the installation to hydraulic cylinder and fixing.
(5) profile is suppressed by multiple hydraulic cylinders in sequence, each hydraulic cylinder is a compacting point, namely carry out spot welding fix when the laminating of steel plate and gusset framework puts in place, a place is welded at the place that fits, multiple hydraulic cylinders form multiple compacting point, multiple compacting points form a press face, and according to the accuracy of manufacture, the quantity of the plurality of compacting point can be selected.
The invention have the advantage that and simple to operate easily improve profile precision, welding will not produce the phenomenons such as gas leakage, misrun.

Detailed description of the invention
Below the present invention is described in further details, sets forth its operation principle:
Detailed description of the invention is:
A kind of flexible manufacturing method in composite material forming model face, including mobile platform and tumbler, mobile platform and tumbler adopt the connected mode of groove semicolumn to connect, tumbler can carry out fan-shaped rotation in the groove of mobile platform, stamped fluid cylinder pressure is installed on tumbler by chute and clamp, and this stamped fluid cylinder pressure can join at the enterprising luggage in multiple positions of tumbler, the rotation of tumbler is driven by rotational hydraulic cylinder;
This method has steps of:
(1) the gusset framework of composite material forming mould is carried out digital control processing by die face, and as the laminating object of reference that profile is accurately suppressed;
(2) by calculating the deformation force of δ=20mm steel plate, it is preferable that steel plate materials is 20#, to determine the specification of hydraulic cylinder, it is preferred between 40t-60t;
(3) drive mobile platform and tumbler, enable stamped fluid cylinder pressure to be perpendicular to the profile of various radian in space, and compacting place is positioned accurately;
(4) on the boss of tumbler, bore hole, location, be used for the installation to hydraulic cylinder and fixing;
(5) profile is suppressed by multiple stamped fluid cylinder pressures in sequence, each stamped fluid cylinder pressure is a compacting point, namely carry out spot welding fix when the laminating of steel plate and gusset framework puts in place, a place is welded at the place that fits, multiple stamped fluid cylinder pressures form multiple compacting point, multiple compacting points form a press face, and according to the accuracy of manufacture, the quantity of the plurality of compacting point can be selected.
More specifically embodiment is (for 3 hydraulic cylinders):
