A workpiece accumulator system for a stamping machine includes linear actuators, nesting blocks, exit rails, and a first controller. The nesting blocks are disposed on moveable members of the linear actuators and arranged to vertically stack workpieces being fabricated by the stamping machine. The first controller communicates with a second controller that controls the stamping machine. The first controller controls the linear positions of the linear actuators to retract the nesting blocks from an initial position to accommodate placement of the one of the plurality of workpieces in a stack on the nesting blocks. The linear actuators are controlled to retract the nesting blocks to fully retracted positions to place the plurality of workpieces in the stack onto the exit rails when a quantity of the plurality of workpieces in the stack is equal to a desired quantity.

While the loading member supporting mechanism moves the loading member from the workpiece set state to the workpiece retracted state and returns to the workpiece set state again, the displacement drive unit and the rotation drive unit perform an operation of disposing the workpiece holding portion arranged at the processing position to the replacement position and an operation of disposing the workpiece holding portion disposed at the replacement position to the processing position in a trajectory in which the loading member does not interfere with the shoe.

The present invention discloses a device for assembling products in a die. The device comprises a pushing portion and an assembling portion. The pushing portion comprises a pushing block (11), a pushing spring (10) and a pushing wedge (9) wherein the pushing block (11) is connected with the pushing spring (10), the pushing wedge (9) is arranged above the pushing block (11) and is in wedge-shaped connection with the pushing block (11). The assembling portion comprises an assembling wedge (6), a transmission wedge (4) and an assembling male die (5), wherein the transmission wedge (4) is arranged above the assembling male die (5) in wedge-shaped connection and both of them are arranged in the lower die base (2), the assembling wedge (6) is arranged above the transmission wedge (4) in wedge-shaped connection while in contact.

The present invention discloses a method for synchronously processing dual belt materials. The method comprises steps of feeding, processing, detecting, assembling and outputting finished products. The step of feeding materials comprises cleaning, dividing materials, positioning and feeding. The step of assembling comprises pushing and assembling. A dual-belt-material feeder is used for feeding, and a dual-belt-material mould is used for punching. The dual-belt-material feeder (1) comprises a moving feeding device (11), a fixed feeding device (13) and two guide frames (14). The dual-belt-material mould comprises two punching moulds. The beneficial effects of the method for synchronously processing dual belt materials are that: the method can be used for producing thin wall miniature assembly parts in a single line and assembling the thin wall miniature assembly parts on line, so that problems caused by that the thin wall miniature assembly parts are produced in two production lines can be avoided.
