Each splint is provided with a U-shaped opening slot, the opening direction of the U-shaped opening slot is the horizontal direction, and the opening directions of the two slots are consistent;

The two side edges of the bottom plate of the protective gear have upwardly folded foot guardrails, the rear ends of the two foot guardrails are connected as a whole by arc-shaped guardrails, and there is a legging extending longitudinally upward on one of the foot guardrails long pole.

The making mold of described leg protector, it comprises:

An H-shaped lower mold as a whole, at least two positioning pins are vertically arranged in the middle of the beam of the H-shaped lower mold;

The overall U-shaped plate-type upper die is provided with two square punches on the bottom surface of the upper die, and a positioning pin hole matching the positioning pin is provided between the two punches. The two punches cooperate with the beam of the H-shaped lower die to punch out the splint of the protective gear;

The mold also includes a concave mold, one side of the concave mold has a ring surface matched with the arc-shaped end of the U-shaped upper mold.

The method for making the leg protector using the mold comprises the following steps:

A. Cut out the required blank after the main body of the protective gear is unfolded along the plane where the bottom plate is located on a sheet metal part;

B. Process the blank, process a positioning hole corresponding to the positioning pin on the lower mold on the bottom plate, and cut two squares on both sides of the positioning hole according to the size and position of the two splints. The opposite sides of each square are connected to the bottom plate, and the remaining three sides of each square are separated from the bottom plate, and a card slot is cut out;

C. Bending the blank to process the foot guards that are folded upwards on both sides of the bottom plate of the protective gear. One of the foot guards has a leggings rod that extends vertically upwards to form a semi-finished protective gear;

D. Assemble the positioning hole on the semi-finished protective gear to the positioning pin of the lower mold, position the semi-finished product, fasten the entire plate-type upper mold on the lower mold, and align the positioning pin hole of the upper mold with the positioning pin of the lower mold. The two square punches of the mold punch the two squares cut in step B, and then punch out two splints perpendicular to the bottom plate of the protective gear;

E. After step D is completed, use the arc section of the U-shaped upper mold as a punch, push the die along the direction parallel to the bottom plate of the protective gear, and close the punch with the punch to bend out two legs. The arc-shaped guardrail between the rear ends of the guardrail;

F. Fix the entire mold, and weld the bent arc-shaped guardrail at the mouth of the die ring surface, so that the arc-shaped guardrail and the foot guardrails on both sides are connected as a whole, and finally form a rehabilitation training machine quick release leg protectors.

Compared with the prior art, the beneficial effects of the present invention are reflected in:

It is easy to use and easy to carry to public places Used on professional training equipment, it can effectively protect the user's feet and ankles.

There is a rubber pad on the opposite inner side of the splint, which can increase the friction between the splint and the side of the pedal, and prevent the protective gear from sliding on the pedal. The user's feet and legs are fixed on the protective gear, and all parts of the protective gear are integrally stamped and formed, so that the processing steps are less and the cost is reduced.

Using the above-mentioned mold to process the quick assembly and disassembly leg protector of the rehabilitation training machine, its processing technology can simplify the processing procedure and reduce the number of clamping times, thereby reducing the clamping error and the time spent on clamping the workpiece, which not only ensures the product quality but also improves the quality of the product. The production efficiency can be improved, and it is suitable for batch production.
