Abstract
The invention relates to a skin pulling stretch forming mould clamping device. A vertical support is arranged on a base and a clamping plate driving hydraulic cylinder is horizontally arranged on the outer surface of the support; the clamping plate driving hydraulic cylinder drives a clamping plate and a clamping plate arc-shaped end is arranged at the front end of the clamping plate; a positioning sensor is arranged on the upper end face of the support. In a part stretch forming process, the device has the optimal direction of blank forming and process characteristics; the invention provides the skin pulling stretch forming mould clamping device which is reasonable in structure, simple to mount, convenient to replace, large in applicable range and low in cost, and a process method thereof, so that the touch direction of a blank with a forming mould in a forming process is an optimal forming direction of the blank, and the forming quality of a skin part is ensured.
Description
Technical field
The invention relates to a kind of skinning surface clamping mould device and process thereof, for the location in aircraft skin class part Stretch Forming Process, belongs to field of machining.
Background technology
Skinning surface is a kind of traditional covering manufacturing process, is widely used in aircraft manufacturing, and the covering particularly for fighter plane is shaped application comparatively extensively, and the forming quality of covering has a strong impact on the life-span of aircraft.In current aircraft skinning surface process, the mould of part is by being placed on pull-shaped equipment workbench manually, riding position and the angle of mould are random, there is no exact requirements, hand labor intensity is large simultaneously, and there is anisotropy due to skinning surface blank, in Stretch Forming Process, if part is not shaped along optimum draw direction, skinning surface part usually there will be skid wire, the defects such as the longitudinal bulge of coarse-grain, therefore whether blank directly affects skin part forming quality along the stretching of optimum shaping direction on mould, so rationally determine blank and mould to contact direction very crucial.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of skinning surface clamping mould device and process thereof, this device is in part Stretch Forming Process, blank shaping optimal direction and process characteristic, there is provided a kind of rational in infrastructure, install simple, be convenient for changing, the scope that is applicable to be large, skinning surface clamping mould device that cost is low and process thereof, blank is contacted with shaping dies in forming process optimum shaping direction that direction is blank, to ensure the forming quality of skin part.
For overcoming the above problems, concrete technical scheme of the present invention is as follows: a kind of skinning surface clamping mould device, pedestal is provided with vertical bearing, is horizontally disposed with clamp drives hydraulic cylinder at the outer surface of bearing, clamp drives Driven by Hydraulic Cylinder clamp, is provided with clamp arced terminus in the front end of clamp; The upper surface of bearing is provided with alignment sensor.
Adopt device as claimed in claim 1 to the process of skinning surface, comprise the following steps:
1) be arranged on movable working platform by some assembling clamp devices, often assembling clamps and is equipped with the two ends that two are arranged in pairs in movable working platform;
2) be placed on pull-shaped mould by skin part to be tensioned, pull-shaped mould is positioned by clamp arced terminus;
3) drive clamp to drive hydraulic cylinder, and monitored by alignment sensor and often organize corresponding clamp whether synchronization telescope;
4) when skin drawing completes, alignment sensor detects the stretching distance of setting, and clamp drives hydraulic cylinder to quit work.
The quantity that described clamping device is arranged limits according to the length of covering, simultaneously the draw direction of clamping device and covering die central axis.
This skinning surface clamping mould device and process thereof can according to the shape of skinning surface mould and sizes, the clamping fixed position of multiple position is adopted to realize the positioning and clamping of multiple kinds of molds, make the optimum draw direction of the contact direction composite blank of mould and blank, complete the pull-shaped technique of skin part, thus ensure forming quality and the aircraft utilization life-span of skin part.
Accompanying drawing explanation
Fig. 1 is the structural representation of skinning surface clamping mould device.
Fig. 2 is skinning surface clamping mould application of installation schematic diagram.
Detailed description of the invention
As shown in Figure 1, a kind of skinning surface clamping mould device, pedestal 8 is provided with vertical bearing 7, is horizontally disposed with clamp drives hydraulic cylinder 6 at the outer surface of bearing 7, and clamp drives hydraulic cylinder 6 to drive clamp 11, is provided with clamp arced terminus 10 in the front end of clamp 11; The upper surface of bearing 7 is provided with alignment sensor 9.This clamping device is designed to freely mount and dismount structure, when using different mould, only needs to change one group or several groups according to the selection of mould size and shape or bar.
Adopt device as claimed in claim 1 to the process of skinning surface, comprise the following steps:
1) be arranged on movable working platform 1 by some assembling clamp devices, as shown in Figure 2, Reference numeral 2-5 is the clamping device of corresponding different group, and often assembling clamps and is equipped with the two ends that two are arranged in pairs in movable working platform 1;
2) be placed on pull-shaped mould by skin part to be tensioned, pull-shaped mould is positioned by clamp arced terminus;
3) drive clamp to drive hydraulic cylinder 6, and monitored by alignment sensor 9 and often organize corresponding clamp 11 whether synchronization telescope;
4) when skin drawing completes, alignment sensor detects the stretching distance of setting, and clamp drives hydraulic cylinder 6 to quit work, and namely completes the drawing work of covering.
The quantity that described clamping device is arranged limits according to the length of covering, four groups are adopted in the present embodiment, the simultaneously draw direction of clamping device and covering die central axis, now the optimum draw direction of blank is vertical with mold center line, now blank is stretched, blank just along optimum draw direction laminating die forming, can complete the shaping of blank along optimum draw direction.
