The specific embodiment
Below in conjunction with drawings and Examples, technical scheme of the present invention is described in further detail.
As shown in Figure 1, 2, this bender protector, it comprises the housing that is built-in with controller, two mechanical arms, mechanical arm 2a, mechanical arm 2b symmetry are arranged on knife rest 1 both sides of bender, two mechanical arm tops are connected with knife rest, mechanical arm 2b, mechanical arm 2a bottom is respectively arranged with laser beam emitting head 6, laser pick-off 3, send and be parallel to by the laser rays that the laser pick-off head receives the blade 5 of knife rest bottom by laser beam emitting head, and be positioned at 2～3mm place, the place ahead of blade, and higher than the point of a knife position 0.5～1mm of blade; The floor push of laser beam emitting head, laser pick-off head, bender, the limit switch of bender, a relay are connected with controller, and relay one end is connected with controller, and the other end is connected with the floor push of bender.
Above-mentioned relay is arranged in the housing that is built-in with controller, and controller also is connected with power supply indicator, floor push indicator lamp, knife rest safe condition indicator lamp and limit switch indicator lamp.With in protector, the limit switch of the bender that is connected with controller refers to the untapped contact of the limit switch of bender in prior art at bender.
Described bender protector, when the limit switch of its bender moved downward to extreme position in order to the knife rest 1 that limits bender, laser beam emitting head 6, laser pick-off 3 quit work; Above-mentioned extreme position be the knife rest 1 of bender move downward to distance workbench 4 be the height of 2～3mm.
As shown in Fig. 3,4,5, described bender protector, its mechanical arm is comprised of rotation section and fixed part, and described rotation section comprises an elongated cylinder 8, elongated cylinder one side is provided with a connecting rod 10, and laser beam emitting head or laser pick-off 3 installed in the connecting rod end; Described fixed part comprises a short cylinder 11, and short cylinder one side is provided with an installing plate 7, and the installing plate end is connected with knife rest 1 sidepiece by bolt 12; Elongated cylinder is identical with the short cylinder diameter, short cylinder 11 tops have boss 18, elongated cylinder 8 bottoms offer the groove corresponding with the short cylinder boss 13, the elongated cylinder center offers tapped through hole, the short cylinder center offers tapped blind hole, both the center is fixedly connected with by thread spindle 14, and the thread spindle upper end is equipped with handle 9.
Uniform screwed holes 15 that several axially connect along the circumferential direction on the elongated cylinder 8 of above-mentioned rotation section, the uniform axial blind hole corresponding with the elongated cylinder screwed hole along the circumferential direction on the short cylinder 11 of fixed part, steel ball 17, retainer spring 16 all are installed in axial blind hole, and retainer spring is arranged in steel ball top and the screw-pressing by being installed in the elongated cylinder screwed hole at elongated cylinder screwed hole, short cylinder axial blind hole.
As shown in Figure 6; described bender protector, it also comprises the gloves 20 that operating personnel wear, the finger position of gloves is provided with micro-pore elastomer 19; the thickness of micro-pore elastomer is 3～5mm, and reduces gradually along finger position root to the end thickness of gloves.Above-mentioned micro-pore elastomer is microporous polyurethane elastomer, high-density sponge or microcellular rubber.
The below describes the course of work that bender of the present invention is used protector in detail.
Protector switches on power, the power supply indicator that is built-in with on the housing of controller is lighted, operating personnel step on floor push, and bender is started working, and the knife rest of bender moves downward, floor push outputs signal to controller simultaneously, controller brings into operation, and sends detection signal, makes laser beam emitting head send laser rays and is received by the laser pick-off head, the floor push indicator lamp is lighted, and has judged whether that simultaneously barrier blocks laser rays and the detectability bit switch signal that whether puts in place; If controller has detected barrier, be hand or the finger that operating personnel wear gloves, stretch under the blade of knife rest and block laser rays, controller sends control signal, and relay is disconnected, and the signal between floor push and knife rest is disconnected, knife rest lifts, return to the initial safe state, knife rest safe condition indicator lamp is lighted, and waits for that operating personnel unclamp floor push; If controller detects without above-mentioned barrier, or after above-mentioned barrier removes, controller is ignored this detection, the knife rest of bender normally moves downward, sheet metal on workbench is carried out bending, and after completing bending work, operating personnel unclamp floor push, knife rest returns to the initial safe state, and the floor push indicator lamp extinguishes; After completing this operation, controller enters inactive state, waits for next operation.
When the knife rest of bender moves downward to distance workbench 2～3mm, controller detects the limit switch signal that puts in place, controller output signal quits work laser beam emitting head, laser pick-off head, the limit switch indicator lamp is lighted, controller stops detecting, and the knife rest of bender continues to move downward the sheet metal on workbench is carried out bending.
The purpose of limit switch is set: in protector when the knife rest of bender moves downward to distance workbench 2～3mm at bender of the present invention; above-mentioned barrier can't stretch under the blade of knife rest; and this moment; knife rest not yet moves to and can carry out to the sheet metal on workbench the position of bending; if laser beam emitting head, laser pick-off head still work on; laser rays can be blocked in the blade point of a knife position of knife rest; cause knife rest to lift and return to the initial safe state, can not complete bending work.
Bender protector of the present invention can carry out bending to all size and the different thin plate that requires, and when allowing blade replacement more, need to install, dismantle two mechanical arms.During dismounting, turning handle becomes flexible the rotation section of mechanical arm and fixed part, and the rotation section that two mechanical arms of laser beam emitting head, laser pick-off head are installed is mentioned; After blade installs, put down the rotation section that two mechanical arms of laser beam emitting head, laser pick-off head will be installed again, screw simultaneously handle in the other direction, steel ball is aimed at the axial blind hole on the fixed part short cylinder, make the laser pick-off head be positioned at the right opposite of laser beam emitting head, realization focuses automatically, completes installation.
Bender protector of the present invention, it is built-in with the e-book that the protector operating instruction is installed in the housing of controller, can realize automatic page turning by the button of installing on housing.
