Detailed description of the invention
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail.
A kind of automatic material jacking structure for cold-punching mould, as shown in Figure 1 and Figure 2, comprise die shoe 8, lower bolster 7, holding pad 3, drift 2 and cope match-plate pattern 1, on described die shoe, lower bolster is installed, template is installed in the top of corresponding lower bolster, this cope match-plate pattern is vertically fixedly mounted with drift downwards, between upper and lower template, holding pad is installed.
Innovative point of the present utility model is:
Described lower bolster upper surface is provided with die assembly 9, this die assembly comprises die 14 and die guide holder 15, as shown in Figure 3, Figure 4, this die guide holder is packed on lower bolster, the laterally inclined die that is slidably fitted with of one, this die drives it to do upper and lower rectilinear motion along die guide holder by being positioned at the ejecting mechanism of die shoe, and the limit assembly that a restriction workpiece moves left and right is installed on described lower bolster.
In the present embodiment, described die and die guide holder are installed together by inclined-plane, this two ends, inclined-plane symmetry is shaped with the oblique groove 16 of pair of angled, between these two oblique grooves, one is vertically shaped with vertical protruding 17, described die guide holder side symmetry is shaped with a pair of oblique draw runner 19 corresponding with described oblique groove, between these two oblique draw runners, be shaped with the vertical groove 18 corresponding with described vertical projection, in the time that die is complete and die guide holder is combined together, between its vertical projection and vertical groove, relative vertical plane does not contact, and retains gapped amount A.
The principle that the relative die guide holder of this die slides is:
In the time that die bottom is subject to jack-up power, the oblique draw runner that groove is shaped with along die guide holder and vertical groove tilt to move up, when the vertical plane relative with vertical groove when vertical projection contacts, die stops moving has realized spacing object, effectively prevents that die and die guide holder from departing from.In order to prevent that die guide holder from following die and moving together, be fixed with block key 6 at the die guide holder opposite side with respect to die.
Described ejecting mechanism comprises spring 11 and jacking block 10, and described jacking block slides and is inlaid in lower bolster, and its top, upper surface is pressed in the lower surface of described die, does up and down rectilinear motion by the Spring driving jacking block of vertical setting.
Described limit assembly comprises tray 5, spring 13 and pilot pin 4, the spring fitting that described tray passes through vertically to arrange is on block key, the holding pad of corresponding described tray is fixed with pilot pin straight down, after this holding pad workpiece pressing 12, the through hole that the bottom of described pilot pin is shaped with through workpiece is also inlaid in the through hole that tray is shaped with.
Operation principle of the present utility model is:
Step 1, is first placed on workpiece on die, and holding pad is by Work-sheet pressing, and the bottom of pilot pin is inlaid in tray, thereby workpiece is located.
Step 2, thus drift moves downward workpiece punch forming, realizes the work of turning over negative angle limit, and drift is removed.
Step 3, holding pad certain distance that moves up, ejecting mechanism drives die to move to upper right side along die guide holder, and by workpiece jack-up, until stop when vertically the projection vertical plane relative with vertical groove contacts, thereby tray is moved up simultaneously and has been ensured that pilot pin is inlaid in tray by Spring driving, and object is to have ensured that workpiece can only move up and can not move left and right, its object is thrown off workpiece and die completely, as shown in Figure 2.
Step 4, holding pad continues to move up, thereby workpiece is taken out.
Thereby this structure is by die assembly and ejecting mechanism being installed on lower bolster by workpiece jack-up, ensured workpiece rectilinear motion and can not moving left and right up and down by limit assembly, thereby can by workpiece fast and die deviate from, be convenient to take off workpiece.Die tilt slide in this structure is arranged on die guide holder side, realized moving up that die tilts, and object is to have realized the workpiece and the die that turn over negative angle limit to deviate from fast.Between die in this structure and die guide holder, be shaped with position limiting structure, thereby prevent that die from moving the problem of throwing off with die guide holder.The utility model is simple in structure, design science is reasonable, makes operator be convenient to take off workpiece, has effectively improved operating efficiency.
It is emphasized that; embodiment described in the utility model is illustrative; instead of determinate; therefore the utility model comprises and is not limited to the embodiment described in detailed description of the invention; every other embodiments that drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope that the utility model is protected equally.
