Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail:
As shown in Figure 1, a kind of moulding runner blanking device, comprise perching knife 10, the shovel seat 20 of fixing perching knife 10, the mechanical gripper 30 of crawl moulding 40, perching knife 10 is provided with blade 110, when to moulding 40 runner 410 blanking, blade 110 and moulding 40 runner 410 are arranged vertically.
Moulding 40 takes out from injection machine by mechanical gripper 30, and moulding 40 is moved to cutting work station, moulding 40 runner 410 is made to face the blade 110 of perching knife 10, perching knife 10 remains that blade 110 is vertical with runner 410 in runner 410 cutting process, reduce the wearing and tearing of blade 110, not only improve cutting-tool's used life, and ensure the quality of product.Cut by the runner 410 of cooperation to moulding 40 of mechanical gripper 30 and perching knife 10, without the need to manual operation, increase work efficiency, reduce cost of labor, and reduce the generation of security incident.
As shown in Figures 2 to 4, perching knife 10 is made up of body 120 and blade 110, blade 110 is made up of back of the body knife face 111, loading end 112, the edge of a knife 113, transition face 114 is arranged with between loading end 112 and the edge of a knife 113, transition face 114 is the cambered surface of band radian, back of the body knife face 111 is inclined-plane, and when to runner 410 blanking, the edge of a knife 113 and runner 410 are arranged vertically.When blade 110 is cut by the edge of a knife 113 pairs of runners 410, during blanking, the edge of a knife 113 and runner 410 are arranged vertically, and reduce the wearing and tearing of the edge of a knife, extend cutting-tool's used life.The edge of a knife 113 profile is 1/3rd of full circle, and its chord length is a bit larger tham the diameter at runner 410 mouth of a river, and the edge of a knife 113 and runner 410 are in vertical state, and perching knife 10 is vertical with runner 410 all the time when shoveling the mouth of a river, and now cutting ability is best.Perching knife 10 is in the process at the shovel mouth of a river, and then stressed the changing from small to big of perching knife 10 diminish, and makes perching knife 10 avoid large impulsive force, improves the stability of cutter.Because runner 410 material is plastics, temperature of having a surplus is with after injection moulding, now runner 410 is softer, transition face 114 is in arc surface, and reduce runner 410 in shovel material process and receive extruding force, runner 410 is out of shape less in cutting-off process, the mouth of a river shoveled out is attractive in appearance, and transition face 114 can reduce the stressed of perching knife 10 for arc surface, facilitates discharge, improve cutting-tool's used life.
In the present embodiment, perching knife 10 body 120 is carbon tool steels, and blade 110 is hard alloy coatings, and perching knife 10 integral rigidity is good, economy and durability.
In shovel material process, as shown in Figure 4, first, the edge of a knife 113 middle section position contacts with runner 410, and along with moulding 40 moves forward, the edge of a knife 113 is expanded from center line toward both sides, runner 410 material enters on loading end 112 through transition face 114 and carries out discharge, shearing force increases gradually, until when perching knife 10 touches runner 410 maximum gauge, shearing force is maximum.Moulding 40 moves forward, and blade 110 and runner 410 contact area diminish gradually, and cutting force reduces, until runner 410 is separated with moulding 40, now cutting force is zero.In whole shovel material process, because moulding 40 is flexible, transition face 114 circular arc can avoid runner 410 mouth of a river in shovel material process to occur the situation of tearing.
As shown in Fig. 1, Fig. 5 to Fig. 7, shovel seat 20 comprises the tool rest 220 of holder 210, fixing perching knife 10, holder 210 is provided with the mounting groove 211 coordinated with tool rest 220, the sidewall of mounting groove 211 is provided with groove 212, tool rest 220 is provided with the projection 221 coordinated with groove 212, and blade 110 stretches out mounting groove 211.By groove 212 and the cooperation of protruding 221, make tool rest 220 and holder 210 that ground is installed more firm, prevent from offseting in the horizontal direction in process.
In the present embodiment, holder 210 is provided with symmetrically arranged two mounting grooves 211, two mounting grooves about 211 and distributes, and is all fixed with tool rest 220 and perching knife 10, two perching knives 10 be arranged in parallel in mounting groove 211.Two mouths of a river are separated by two perching knives 10 simultaneously, increase work efficiency further.Holder 210 can also arrange more than one mounting groove 211 according to actual needs.
As shown in Figures 5 to 7, the surrounding sidewall of mounting groove 211 is provided with the vertical groove 212 arranged, and tool rest 220 is provided with the projection 221 coordinated with groove 212, when installing tool rest 220, projection 221 and groove 212 are alignd, and tool rest 220 is mounted in mounting groove 211 from top to bottom along groove 212.Groove 212 can also be arranged on tool rest 220 according to actual needs, is correspondingly arranged on protruding 221 on the sidewall of mounting groove 211.
As shown in Figure 6 and Figure 7, be convexly equipped with erecting bed 213 in mounting groove 211, erecting bed 213 is provided with the first inclined-plane 214, and tool rest 220 is provided with the second inclined-plane 222 coordinated with the first inclined-plane 214.By the cooperation on the first inclined-plane 214 and the second inclined-plane 222, facilitate the installation of tool rest 220 on holder 210 and the location at vertical direction.
As shown in Figure 5, shovel seat 20 also comprises baffle plate 230, and baffle plate 230 is located at the side of holder 210 away from blade 110.Prevent in shovel material process, because shovel seat 20 is stressed excessive and play occurs.
In the present embodiment, as illustrated in figures 1 and 8, moulding 40 is insert injection moulding part, moulding runner blanking device comprises two shovel seats 20, when mounting arrangements, two shovel seats 20 are bolted on the workbench 50 of lathe, perching knife 10 is fixed by high-strength bolt and shovel seat 20, each shovel seat 20 installs two perching knives 10, and two perching knife 10 installation sites are arranged symmetrically with, the back of the body knife face 111 of one of them perching knife 10 upward, the back of the body knife face 111 of another perching knife 10 down, distance between back of the body knife face 111 equals runner 410 slit shearing distance.When installing two shovel seats 20, make to become to be arranged in parallel between two shovel seats 20, the distance of shovel seat 20 centreline space is the transversely cutting distance of a runner 410, and now carry on the back knife face 111 and all contact with moulding 40, transition face 114 contacts with runner 410.Moulding runner blanking device is equipped with four perching knives be arranged symmetrically with 10 simultaneously, and can be realized the separation at four mouths of a river by a blanking action, operating efficiency is high simultaneously.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this description is recorded.
