Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of plate shearing machine, as shown in Figure 1 to Figure 2, including the frame 1 on ground, it is provided with to enter for plate in frame 1 The charging aperture 2 and some presser feets 3 for being used to fix plate, length direction of the presser feet 3 along frame 1 entered is equidistantly arranged at intervals, And distance of the lower end away from plate of all presser feets 3 is equal, wherein the lower end of a presser feet 3 is provided with JHBM pressure sensors 6, Distance of the sensor of JHBM pressure sensors 6 away from other lower ends of presser feet 3 tool plate is equal, and the side of frame 1 is additionally provided with external Hazard warning flasher 7 and built-in alarm speaker 8.
As shown in figure 3, frame 1 is hinged with blanking plate 4 away from the side of charging aperture 2, blanking plate 4 is with the length side of frame 1 Rotated upwardly and downwardly to for rotary shaft, be arranged at intervals with some bar-shaped troughs 41 on blanking plate 4, and bar-shaped trough 41 is along blanking plate 4 Length direction is equidistantly arranged at intervals.
As shown in Fig. 4 to Fig. 5, the lower section of blanking plate 4 is provided with holding tank 5, and holding tank 5 includes the support fixed with frame 1 Frame 51, both sides of the support frame 51 along the length direction of frame 1 have been respectively articulated with cylinder 9, the other end of cylinder 9 respectively with blanking plate 4 Downside be hinged, and cylinder 9 is parallel to each other with rotary shaft of the hinge axes of support frame 51 and blanking plate 4 with blanking plate 4, Width sliding of the support frame 51 along frame 1 is connected with crumb loading groove 52, and all bar-shaped troughs 41 are respectively provided with and crumb loading groove 52 Top.
As shown in Figure 6 to 7, JHBM pressure sensors 6 are electrically connected in over-pressed instruction system, JHBM pressure sensors The pressure that 6 presser feets 3 for being provided with JHBM pressure sensors 6 apply to plate detect and output detection value, due to all pressures Pin 3 and JHBM pressure sensors 6 are equal with the distance between plate, so all presser feet 3 and JHBM pressure sensors 6 It is almost equal for the pressure of plate, so can obtain presser feet 3 for the pressure of plate by measuring JHBM pressure sensors 6 The pressure applied to plate.
JHBM pressure sensors 6 are electrically connected with comparator, and comparator exports when detected value exceedes maximum pressure threshold value Over-pressed signal, wherein detected value and maximum pressure threshold value are arranged to voltage analog, and over-pressed signal is arranged to high level.Comparator Normally opened contact relay is connected with, the normally opened contact of normally opened contact relay is connected to alarm speaker 8 and the institute of hazard warning flasher 7 Loop in.
Comparator is arranged to MAX919 comparators, and the in-phase input end of MAX919 comparators inputs a reference voltage, i.e., most Big pressure threshold, the anti-phase input item of MAX919 comparators are coupled to JHBM pressure sensors 6, the output end of MAX919 comparators Timing circuit is coupled to, timing circuit includes counter, register and crystal oscillator, and the output end of timing circuit is coupled to metal-oxide-semiconductor Grid, the both ends in loop, normally opened contact where the source electrode of metal-oxide-semiconductor and drain electrode are respectively coupled to the coil of normally opened contact relay The coils from parallel connection of coils of relay has fly-wheel diode, and the normally opened contact of normally opened contact relay is coupled to alarm speaker 8 and alarm Loop where flash lamp 7.
When being sheared using plate shearing machine to plate, plate is delivered in charging aperture 2 first, and is positioned over position to be sheared Place is put, then all presser feets 3 are pushed so that presser feet 3 is all inconsistent with plate, wherein the JHBM of the lower end of a presser feet 3 Pressure sensor 6 is also inconsistent with plate, and now JHBM pressure sensors 6 are examined in real time to plate by the pressure of presser feet 3 Survey, when pressure is normal, detected value is less than maximum pressure threshold value, so MAX919 comparators output low level, now metal-oxide-semiconductor Grid is low level, so metal-oxide-semiconductor is not turned on, does not have electric current in the coil of normally opened contact relay, normally opened contact remains open State, alarm speaker 8 and the place loop of hazard warning flasher 7 are not turned on, so alarm speaker 8 does not send sound, and are alarmed Flash lamp 7 does not light;When presser feet 3 is higher than maximum pressure threshold value for the pressure of plate, MAX919 comparators output high level, Now metal-oxide-semiconductor is turned on, and has electric current to flow through in the coil of normally opened contact relay, so now normally opened contact closes, alarm is raised one's voice Device 8 and the conducting of the place loop of hazard warning flasher 7, alarm speaker 8 sends alarm sound, and hazard warning flasher 7 is glistened to behaviour Prompted as personnel, prompt operating personnel that the position of presser feet 3 need to be adjusted.
It is different according to the specification of plate after presser feet 3 completes fixed operation to plate, the angle of inclination of blanking plate 4 is entered Row regulation, start two cylinders 9 and stretched so that blanking plate 4 is rotated upwardly and downwardly, until blanking plate 4 goes to braking angle Place stops cylinder 9, and then plate shearing machine is sheared by cutter head to plate, and metal fragment can be produced in shear history, shears After the completion of, the part being sheared on plate is dropped down onto on blanking plate 4, because blanking plate 4 is obliquely installed, so the shearing part of plate Because the gravity of itself slides downwards from blanking plate 4, during plate slides, chip also slides therewith, when chip passes through When crossing bar-shaped trough 41, chip can be fallen to due to the Action of Gravity Field of itself in the crumb loading groove 52 of the lower section of blanking plate 4, pass through crumb loading groove 52 pairs of chips are collected.
When the talus accumulation in crumb loading groove 52 to it is a certain amount of when, start cylinder 9 cause cylinder 9 extend, due to cylinder 9 simultaneously It is be hinged with support frame 51 and blanking plate 4, so the elongation of cylinder 9 promotes blanking plate 4 to be rotated up so that crumb loading groove 52 by Fade in and expose, when crumb loading groove 52 reveals completely, close cylinder 9 so that blanking plate 4 keeps the state opened, now Line slip is entered to crumb loading groove 52 again so that operating personnel are easy to clear up the chip in crumb loading groove 52.
The above embodiments are only that it is not to limitation of the present utility model, ability to explanation of the present utility model Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but As long as all protected in right of the present utility model by Patent Law.
