Description

Technical Field

[0001] The present application belongs to the technical field of pick-and-place equipment, and specifically relates to a pick-and-place equipment for hot-pressed sheet metal parts of aircraft. Background Art

[0002] When hot forming aircraft titanium alloy sheet metal parts, it is usually necessary to apply a protective layer to the surface of the titanium alloy blank, heat the forming machine, and when the temperature reaches 700-750℃, put the titanium alloy blank with the protective layer into the hot forming mold for heating. The upper and lower molds of the hot forming mold are closed to maintain pressure, and the titanium alloy blank is stamped into shape. After the upper and lower molds of the hot forming mold are opened, the titanium alloy special-shaped surface parts are taken out and cooled naturally.

[0003] Aircraft hot-pressed sheet metal parts are usually thin plate parts with large size. After high-temperature forming, the walls are thin and the shapes are irregular. They are prone to deformation. Traditional manual material removal has low production efficiency. In addition, since the formed parts fit tightly with the mold, traditional manual labor generally uses single-point prying and long-arm pliers to clamp the parts. The parts are subjected to large local forces and are prone to excessive deformation or even scrapping. The product yield is low. In order to facilitate the stable picking and placing of thermoformed aircraft hot-pressed sheet metal parts and reduce the scrap rate. Summary of the invention

[0004] Purpose of the invention: To provide a picking and placing device for aircraft hot-pressed sheet metal parts, which solves the problems raised in the above-mentioned background technology, can electrically pick and place aircraft hot-pressed sheet metal parts, without the need for workers to approach a more stable thermoforming machine, has better safety, and can prevent damage to the aircraft hot-pressed sheet metal parts during prying and clamping, so that aircraft hot-pressed sheet metal parts that are tightly fitted to the mold can be safely and stably removed and placed, reducing the scrap rate.

[0006] The supporting and placing assembly is used to place the sheet into the equipment; wherein, after hot pressing and forming, the supporting and placing assembly is also used to hold up the parts and deliver the parts under the action of the sliding assembly;

[0007] A sliding assembly is connected to the supporting assembly. When the supporting assembly feeds in the raw material or takes out the parts, the sliding assembly drives the supporting assembly to slide to the inside or outside of the hot forming furnace;

[0008] A lifting component is connected to the sliding component, and the lifting component is used to adjust the height of the supporting component.

[0009] Preferably, the holding, placing and taking assembly comprises:

[0013] Two bidirectional lead screws are connected to the brake stepping motor;

[0014] Two clamping plates are threadedly connected to the bidirectional lead screw, wherein the brake stepping motor drives the bidirectional lead screw to rotate, and the clamping plates move toward the clamping frame until the lower mold is clamped.

[0015] Preferably, the holding, placing and taking component further comprises:

[0016] A synchronous wheel, arranged on the bidirectional lead screw;

[0025] Preferably, the pick-and-place bracket and the load-bearing bracket are both made of high-temperature resistant alloy material.

[0026] This application has the following technical effects:

[0027] The present application proposes a device for picking and placing aircraft hot-pressed sheet metal parts, which can cooperate with corresponding molds to flip the molded aircraft hot-pressed sheet metal parts and remove them. Traditionally, long-handled pliers are used to clamp and pick up parts at a local single point, which may cause local deformation of the clamping point for thinner parts, affecting the quality of the parts. The new structure adopts a whole-edge lifting method for picking and placing, which has no effect on the appearance of the parts. This prevents damage to the aircraft hot-pressed sheet metal parts during the prying and clamping process, so that the aircraft hot-pressed sheet metal parts that are tightly fitted to the mold can be safely and stably removed and placed for subsequent natural cooling.

[0028] At the same time, when hot forming parts are taken in and out, the internal temperature of the equipment is about 700℃, and the temperature outside the furnace door is high when opening and closing the furnace door to take materials. Operators need to wear special protective clothing and can only operate for a short time, which requires high workload. The new structure is easy to operate and can keep a certain distance from the furnace door, which greatly improves the working environment of operators and reduces labor intensity.
