Axis setting.
By using above-mentioned technical proposal, on the one hand graphite copper sheathing serves is oriented to wear-resisting, another aspect self-lubricating work
With reducing its frictional force with limited post.
Further, the clamping members is spring, and the spring pocket is set on limited post, and the spring is far from lower mold
One end is affixed with link block, and the other end is vacantly arranged；
When upper mold protrudes the lower end surface of this part and prepreg just contradicts, the spring is in former long status；
When upper mold protrusion is partially submerged into lower mold depressed section, the spring is in compressive state.
By using above-mentioned technical proposal, using the self-characteristic of spring, the spring-compressed in molding, therefore, spring to
Under restoring force act on profile one, the pressure that prepreg is born be profile one self weight and spring it is downward to profile one
The resultant force of restoring force further steps up prepreg both ends, makes prepreg be not easy to concentrate to middle part, the cap for forming molding
Type stringer thickness is uniform, improves the Forming Quality of shape for hat stringer.
Further, the heating member is infrared hot plate.
By using above-mentioned technical proposal, infrared hot plate does not need medium heat-transfer, temperature control is easy and heating is rapid, has
Penetration power heats prepreg using infrared hot plate, is uniformly heated prepreg, and heating efficiency is high.
Further, the both ends of a lateral edge upper mold width direction of the upper mold far from lower mold have upwardly extended lock
Tight block is fixed with mounting blocks corresponding with latch segment on the profile one, and the latch segment is connected with mounting blocks by locking member.
By using above-mentioned technical proposal, when upper mold does not work, profile one is fixed by locking member and upper mold, side
Just the handling of prepreg.
Further, the driving device is cylinder.
By using above-mentioned technical proposal, the automatic control of upper mold can be realized using cylinder.
In conclusion the utility model has the following beneficial effects:
Using spring as clamping members, using the self-characteristic of spring, the spring-compressed in molding, therefore, spring to
Under restoring force act on profile one, the pressure that prepreg is born be profile one self weight and spring it is downward to profile one
The resultant force of restoring force further steps up prepreg both ends, makes prepreg be not easy to concentrate to middle part, the cap for forming molding
Type stringer thickness is uniform, improves the Forming Quality of shape for hat stringer.
