Crust bending apparatus

A crust bending apparatus, which is adapted to bend a crust for enclosing an electrical connector, comprising:

• a positioning assembly, which comprises a conveyance cylinder, a conveyance block, a holding cylinder, a holding rod, a holding block, a positioning cylinder, a positioning rod, and a positioning block, wherein the conveyance cylinder, the conveyance block, the holding cylinder, the holding rod, the holding block are arranged horizontally in such a way that the conveyance cylinder is coupled to a front end of the conveyance block, a rear end of the conveyance block being positioned against an end of the holding rod, an opposite end of the holding rod being coupled to the holding cylinder, and wherein the positioning cylinder, the positioning rod, and the positioning block are arranged vertically in such a way that the positioning cylinder is coupled through the positioning rod to an upper end of the positioning block and a lower end of the positioning block is engageable with the rear end portion of the conveyance block;
• and
• a bending assembly, which is set adjacent to the positioning assembly so that the crush is conveyed by the positioning assembly to a predetermined position in the bending assembly for performing a bending operation, the bending assembly comprising a bending cylinder, a bending rod, a bending block, and a line-to-rotation conversion member, the bending block comprising coupling portions that are located on opposite sides and are substantially rectangular and a bending portion connected between the coupling portions, the bending portion having an underside forming a bending surface, the line-to-rotation conversion member being of a rectangular configuration and forming a position constraint slot, the bending rod having an end coupled to the bending cylinder and an opposite end forming a projection having a circular cross-section on a side surface of the end and received, in a rotatable and movable manner, in the position constraint slot.
