A kind of double hook hooping forming machine of the present invention is when specific works, operator will treat that the reinforcing bar of bending process is placed on blanking device for placing the base plate of the horizontal component of material, when reinforcing bar arrives hopper sloping portion, can slip between discharge device and the base plate of sloping portion under self gravitation effect, and keep falling along the base plate of sloping portion.In landing process, because the gap of drawing between material bar and sloping portion base plate can only hold a reinforcing bar, therefore drawing material bar can play restriction to the arrangement of reinforcing bar.And due to the width of hopper and the length of reinforcing bar basically identical, there is not the phenomenon of inclination in reinforcing bar.Reinforcing bar under effect established by the card of discharge device, can only one then order be arranged in the sloping portion of hopper, and order evenly blanking is in the station groove of bending device, this station groove can play stretcher to reinforcing bar and card is established, restriction.Now, the output shaft of drive unit drives pull bar to act on up and down, the end of pull bar is a ball head connecting device, namely the bulb of connecting rod end is arranged in ball-head cover that the bottom transverse slat of the U-shaped drift of opening upwards is installed, the both sides of U-shaped drift are provided with track, and U-shaped drift can slide up and down in orbit.The below of drift is bolted a U-shaped pressure head that Open Side Down, and the downward punching press of U-shaped pressure head makes strip reinforcing bar be bent into the U-shaped structure matched with U-shaped pressure head inner fovea part.In order to prevent reinforcing bar when bending, two ends apply curved power downwards, middle part can be arched upward bending because of extrusion stress effect to middle part, device is provided with coalignment, the spring of coalignment is arranged in a cavity of pressure head top, drift inside, it cushions abatement and upwards pressure when reinforcing bar bends, and elastic force is acted on reinforcing bar top, prevents reinforcing bar top from arching upward.
After having bent, U-shaped reinforcing bar in station groove pushes away and drops down onto crotch station by material-pulling device, in material-pulling device, be chain annexation for the driving wheel for driving cam in the driving wheel that bends and material-pulling device, namely ensure that bending device often bends a reinforcing bar, the cam of material-pulling device just in time runs to cam top cover place, and the boss on cam drives top cover and connecting rod to rotate around fulcrum, and then drives the complete pusher operation to reinforcing bar after bending of charging ram horizontal movement.The through hole of the support body side of material-pulling device, after self-lubricating bearing pairing is loaded elastic shaft sleeve in the overall through hole loading support body, charging ram is located in the hole at self-lubricating bearing center, load positioning and locking screw by support body top again and elastic shaft sleeve is locked at through hole inside, charging ram can at guide shaft support sweeping action.After device starts, along with the lifting of temperature after mechanical friction, self-lubricating bearing can form oil film in the contact surface of charging ram, to strengthen the lubricant effect of charging ram, reduces noise.
The thrust that U-shaped reinforcing bar is subject to poking device carries out crotch operation from bending in station groove to fall in crotch station groove.Now, Open Side Down for U-shaped reinforcing bar, and this crotch station groove can play stretcher to U-shaped reinforcing bar and block the effect of establishing, limiting.The now output shaft drivening rod horizontal traversal of drive unit, the end of connecting rod is a ball head connecting device, namely the bulb of connecting rod end is arranged in ball-head cover that slide is installed, the two ends of slide connect two slide bars be arranged in parallel, the slide rail that two slide bars can be established in frame moves back and forth, and the end of slide bar is connected with a punch rod, this punch rod carries out punching press crotch by with the slip of slide bar on slide rail to the two ends of U-shaped reinforcing bar.Namely the station groove of U-shaped reinforcing bar is established to be arranged on the inside of the rectangle frame be made up of slide, two slide bars and punch rod for card.The structure and the devices such as slide, two slide bars and punch rod employing bolt are fixed as one, punch rod carries out crotch punching press along with pull bar moves.In order to prevent U-shaped reinforcing bar when two ends crotch, medium position can be distorted because of impact force action bending, power apparatus is provided with back in device, the spring returning power apparatus is fixed in the frame of top end of sliding rod by a fixture, spring is provided with a flat time power plate towards one end of station groove, and this time power plate is used for acting on U-shaped reinforcing bar top, cushions this surge suffered by reinforcing bar of position, prevent reinforcing bar deforming tops, and can be kicked down after reinforcing bar crotch in splicing case.
Structure of the present invention is simple, good practical effect, has saved crotch operation, has improve production efficiency, ensure that carrying out continually and steadily of production, be applicable to promoting the use of.
