ActiveCN104439014BRealize automated productionIncrease productivityForging/hammering/pressing machinesProduction linePunch press
The invention discloses a full automatic fastener forging and pressing manipulator production line. The full automatic fastener forging and pressing manipulator production line comprises a control system, a storage box, an automatic elevator, a roller feeding device, a high frequency heating furnace, a feeding machine, a flattening punch, a first manipulator, a second manipulator, a forging and pressing punch and a power distribution cabinet, wherein the automatic elevator, the roller feeding device, the high frequency heating furnace, the feeding machine, the flattening punch, the first manipulator, the second manipulator, the forging and pressing punch and the power distribution cabinet are electrically connected with the control system. The automatic elevator is used for elevating materials in the storage box, adjusting the direction and conveying the materials to the roller feeding device, the roller feeding device is used for conveying the materials to the high frequency heating furnace, the high frequency heating furnace is used for heating the materials to a set temperature, the heated materials are conveyed to a locating position through the feeding machine and located to be clamped by the first manipulator, the first manipulator is used for clamping the materials and conveying the materials to the flattening punch, and the materials are flattened for the first time, then rotated by 90 degrees and flattened for the second time. The second manipulator is used for clamping a product and moving the product to the forging and pressing punch for forging and pressing forming. The power distribution cabinet is arranged on one side of the first manipulator. Through the full automatic fastener forging and pressing manipulator production line, automatic production of fasteners is achieved, and production efficiency is improved.

Multifunctional hydraulic track forging manipulator
ActiveCN102430684BExpand the scope of workReduce intermediate auxiliary timeForging/hammering/pressing machinesControl systemForging manipulator
A multifunctional hydraulic track forging manipulator is disclosed, and comprises a body travelling device connected with a four connecting rod mechanism. Both a rotary oil connector and a conductive slip ring are connected with the body travelling device; a hydraulic control system, an electric control system and an operating cab are respectively connected with the four connecting rod mechanism; the electric controls system is installed in a space of the operating cab; the whole device is located on a ground track of a workshop; and the four connecting rod mechanism is connected with a pincers frame so as to form an integral piece. The body travelling device supports the whole four connecting rod mechanism and the pincers frame. The pincers frame is a structure of multilayer sleeve so that the claw beam of the pincers frame is retractable, thereby effectively expanding the working range of the manipulator and realizing the functions of the manipulator and a charging and discharging machine on a same manipulator. The invention improves the production efficiency and eliminates the danger of workers in the process of conveying the forging materials.
