The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby protection domain of the present utility model is made more explicit defining so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that.
As described in Figure 1, present embodiment comprises patrix 1, material 2, counterdie 3, fixed guide piece 4, vertical push rod 5, spring 6, the piece 7 that fluctuates, guide rail 8, guide pad 9, forced resetting piece 10, plug 11, forced resetting dashes 12, fixed block 13, horizontal push rod 14, punching press head 15, upper bolster 16, die shoe 17, machine base 18.
Position that each member is concrete and annexation are: described patrix 1 is installed on the upper bolster 16, counterdie 3 is installed on the die shoe 17, material 2 is floated between patrix 1 and counterdie 3 by servicing unit, material 2 needs the position and the plug 11 of volume circle to be positioned at same level, the described fixed guide piece 4 and the piece 7 that fluctuates are installed in plug 11 front ends, and described piece 7 lower ends of fluctuating contact with the vertical push rod 5 of band spring.Described fixed guide piece 4 is fixing with respect to machine base 18, can be fixed on the die shoe 17, also can be fixed on the machine base 18, and the utility model is not done concrete restriction to its fixed form and fixed position, can select according to actual needs; The described piece 7 that fluctuates can fluctuate with respect to machine base 18.In the described guide pad 9 vertical guide rail or vertical clamping slot are arranged, plug 11 rear ends are installed in wherein, and guide pad 9 and fixed guide piece 4 one work, the track that moves both vertically of restriction plug 11.The rear end face of guide pad 9 is connected by retaining element with the front end face of forced resetting piece 10, and is installed in together on the horizontal guide rail 8.The rear end face of forced resetting piece 10 is connected with the horizontal push rod 14 of a band spring, there is the gathering sill of a up/down perforation described forced resetting piece 10 inside, described forced resetting dashes 10 and is bending, the upper end is connected with punching press head 15, the lower end places gathering sill, it is consistent that described gathering sill has two spacing inclined-planes and described forced resetting to dash 10 bending inclined-plane, and described forced resetting dashes 10 and can pass in gathering sill.
In conjunction with Fig. 2, shown in Figure 3, describe the course of work of the present utility model down as Fig. 1 in detail:
A, punching press downwards drive plug to the operating position, as shown in Figure 2: the downward punching press of described punching press head 15 beginnings, punching press head 15 drives the forced resetting that connects thereon and moves downward towards 12, forced resetting dashes the cooperation that contacts with first guiding surface of forced resetting piece 10 of 12 bending lower inclined plane, forced resetting dash 12 move downward generation on the inclined-plane, can decomposite a part of level active force forward to lower punch power, travel forward along horizontal guide rail 8 thereby drive forced resetting piece 10, further drive plug 11 and move forward into the operating position;
B, continue downward punching press, finish punching press volume circle, as shown in Figure 3: along with punching press head 15 continue move downward, punching press head 15 and then drive upper bolster and patrix move downward, finish the action of punching press volume circle with the counterdie matched moulds together up to driving material 2 and plug 11, plug 11 drives the piece 7 that fluctuates and moves downward, and the vertical push rod 5 of piece 7 further compressings that fluctuates makes its back-moving spring 6 downwards by compression.
C, upwards reset to position as shown in Figure 2: under the driving of stamping machine backhaul, punching press head 15 drives forced resetting and upwards resets towards 12, upper bolster 16, patrix 1, material 2 also upwards reset under corresponding backhaul drives, under the spring restoring force effect of the back-moving spring 6 of vertical push rod 5, vertical push rod 5 upwards resets, the drive piece 7 that fluctuates upwards resets, thereby further drives plug 11 by upwards resetting.
D, loosing core resets to position as shown in Figure 1: after horizontal reset is reached, forced resetting dashes the cooperation that contacts with second guiding surface of forced resetting piece 10 of 12 bending ramp, forced resetting dashes 12 active forces that upwards reset, on the inclined-plane, decomposite a part of level active force backward, move backward along horizontal guide rail thereby drive forced resetting piece 10, further drive plug 11 and finish the action of loosing core backward.Because of the application of force that upwards resets of punching press head 15 limited, for guaranteeing resetting smoothly of forced resetting piece 10, the rear end that also comprises a horizontal push rod and forced resetting piece 10 in the present embodiment is connected, the horizontal push rod of forced resetting piece 10 drives travels forward, make the back-moving spring compression of horizontal push rod rear end, when resetting backward, back-moving spring also can provide the corresponding horizontal reset force.The front end of the horizontal push rod 14 in the present embodiment is threaded structure, can be directly and forced resetting piece 10 be threaded, also can adopt other attaching parts to be connected and fixed such as bolt, screw etc., enumerate no longer one by one in the utility model.
The above; it only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
