Description

Technical Field

[0001] The utility model relates to the technical field of exoskeleton manufacturing, in particular to a flexible material exoskeleton forming machine. Background Art

[0002] A flexible material exoskeleton is an auxiliary device made of soft, thin and flexible materials or components, aiming to assist the movement of various body joints, such as the bending and stretching of the forearm, etc. It works in parallel with human muscles and ligaments, transfers the pulling force to the human body through a specific load path, and generates an auxiliary torque at the biological joints, and is manufactured by a forming machine.

[0003] During the manufacturing process of the exoskeleton, it is necessary to heat the flexible material to a certain temperature to make it soft and easy to shape. At this time, the material is shaped through the mold or fixture of the forming machine to form the required exoskeleton structure.

[0004] However, the existing forming machines have the following problems: when the material is plastically formed through the mold, the temperature of the general material is relatively high and it takes a long time to cool, which is likely to cause inconvenience during the manufacturing of a large number of exoskeletons, and when demolding, the formed material is likely to adhere to the mold, making it inconvenient to separate. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages that when the material is plastically formed through the mold in the prior art, the temperature of the general material is relatively high and it takes a long time to cool, which is likely to cause inconvenience during the manufacturing of a large number of exoskeletons, and when demolding, the formed material is likely to adhere to the mold, making it inconvenient to separate, and a flexible material exoskeleton forming machine is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A forming mechanism is arranged on the top plate to facilitate the forming of the exoskeleton;

[0009] A demolding mechanism is arranged inside the bottom box to facilitate the demolding of the formed material.

[0010] In a possible design, the forming mechanism includes two hydraulic cylinders, four springs, four positioning rods and two side plates. The two sides of the upper die are fixedly connected to the adjacent sides of the two side plates respectively. The fixed ends of the two hydraulic cylinders are fixedly connected to the two sides of the top of the same top plate respectively. The telescopic ends of the two hydraulic cylinders are fixedly connected to the centers of the bottoms of the two side plates respectively. One ends of the four positioning rods are fixedly connected to the top of the same top plate. The other ends of the four positioning rods respectively penetrate through the two sides of the bottoms of the two side plates and extend above the side plates. Limit plates are fixedly connected to the other ends of the four positioning rods. The four springs are respectively sleeved on the four positioning rods, and the two ends of the four springs are fixedly connected to the adjacent sides of the side plates and the top plate respectively.

[0011] In a possible design, the demoulding mechanism includes two L-shaped plates, a motor, two synchronous belts, two rotating columns, an inner plate, two threaded rods, two lifting plates, a connecting plate and a plurality of ejector pins. The adjacent sides of the two L-shaped plates are fixedly connected to the two sides of the same motor through bolts respectively. The bottoms of the two L-shaped plates are fixedly connected to the inner wall of the bottom of the same bottom box. The output shaft of the motor is fixedly connected with a first column, and one end of the first column is rotatably connected to the bottom of the inner plate. The two sides of the inner plate are fixedly connected to the inner walls of the two sides of the same bottom box respectively. One ends of the two rotating columns are rotatably connected to the inner wall of the bottom of the same bottom box respectively. Synchronous wheels are sleeved on the two rotating columns respectively. The two rotating columns are mutually driven by the synchronous belts and the first column respectively. The other ends of the two rotating columns respectively penetrate through the two sides of the bottom of the same inner plate and are rotatably connected to the inner plate. The other ends of the two rotating columns are fixedly connected to one ends of the two threaded rods respectively. The other ends of the two threaded rods are rotatably connected to the two sides of the bottom of the same top plate respectively. The two lifting plates are respectively threadedly sleeved on the two threaded rods. The adjacent sides of the two lifting plates are fixedly connected to the two sides of the same connecting plate respectively. A plurality of ejector pins are fixedly arranged on the top of the same connecting plate. One ends of the plurality of ejector pins are fixedly connected to the bottoms of the three inner blocks respectively.

[0012] In a possible design, a plurality of cooling pipes are arranged inside the lower die. The plurality of cooling pipes are all connected to each other and form two cooling rings. Liquid inlet ends and liquid outlet ends are fixedly arranged on the two cooling rings respectively. Liquid inlet pipes are fixedly arranged on the two liquid inlet ends and the two liquid outlet ends respectively. The plurality of liquid inlet pipes all extend to the outside of the lower die and are provided with pipe caps.

[0013] In a possible design, sliders for facilitating the stable movement of the connecting plate are fixedly connected to the opposite sides of the two lifting plates respectively.

[0014] In a possible design, heat dissipation holes for facilitating the heat dissipation of the motor are formed in the bottom of the bottom box, and a dust-proof net for preventing foreign objects from entering is fixedly arranged on the inner wall of the heat dissipation holes through bolts.

[0015] In this application, during use, in the initial state, the upper mold is located above the lower mold, and there is sufficient space between the two for placing the flexible material. The operator starts the forming mechanism through the controller, and the hydraulic cylinder starts to work. The telescopic end pushes the two side plates to drive the upper mold to move downward until the upper mold is in close contact with the lower mold, compressing the flexible material into a shape. During the forming process, the positioning rod and the spring play a guiding and buffering role to ensure the smooth descent of the upper mold. When the flexible material is completely formed, the operator starts the forming mechanism again through the controller to separate the upper and lower molds from each other. During the forming process, the coolant in the cooling pipe cools the high-temperature material in the lower mold, accelerating the cooling speed, thereby improving the exoskeleton manufacturing efficiency. The lower mold is cooled by two cooling rings to accelerate the curing process of the flexible material. The motor is started through the controller, and the motor drives the first column to rotate. Then, through the synchronous belt, the two rotating columns rotate. The design of the heat dissipation holes and the dust-proof net at the bottom of the bottom box not only ensures the heat dissipation effect of the motor but also prevents foreign objects from entering the interior of the bottom box, ensuring the normal operation of the equipment. The rotation of the rotating columns causes the two threaded columns to rotate simultaneously. The lifting plate on the threaded column moves upward under the action of the thread. The lifting plate is slidably connected through the slider and the chute, ensuring the stability of the connecting plate during the lifting process and avoiding the failure of demolding caused by shaking. The movement of the lifting plate drives the connecting plate and the top column to rise, and the top column pushes the inner block upward, so that the formed exoskeleton is detached from the lower mold. The threaded lifting mechanism driven by the motor realizes the automatic detachment of the formed exoskeleton from the lower mold, greatly improving the production efficiency and reducing the labor intensity of workers.

[0016] The beneficial effects of the present utility model are as follows:

[0017] In the present utility model, through the forming mechanism and the demolding mechanism, the formed exoskeleton is automatically detached from the lower mold, greatly improving the production efficiency and reducing the labor intensity of workers. At the same time, cooling pipes are provided to form two cooling rings to uniformly cool the lower mold, effectively shortening the curing time of the flexible material and improving the production efficiency.
