Abstract
The invention discloses a lever type thin material cutting mechanism which comprises a cutting tool. The cutting tool is arranged on the body of a machine; a cantilever is arranged above one side of the cutting tool, and the other side of the cutting tool is provided with a supporting block relative to the cantilever; one end of a beating rod is connected with the cantilever, and the other end of the beating rod is hinged on the supporting block; one end of the beating rod, which is near to the supporting block, is provided with a beating rolling beam; and the beating rolling beam contacts a beating cushion block which is arranged on an upper cutter fixing plate of the cutting tool. The destructive force produced by the direct acting of the cantilever is greatly reduced, and the cantilever is remarkable in long-time high-speed working effect. In addition, a rolling bearing is arranged between the bearing rod and the supporting block, and the rolling bearing and the beating rolling beam rotate in a reciprocating way during working, so that the wear of the surfaces due to long-term working is avoided, and the service lives are prolonged.
Description
Technical field
The present invention relates to a kind of thin material die cutting die, relate in particular to the thin material of a kind of lever shut-off mechanism.
Background technology
At present, it is directly to act on the upper slitter fixed head by cantilever that common thin material cuts off, and approaches the material cut-out through cutting off upper slitter.Can cause phenomenons such as cantilever distortion, bending, the wearing and tearing of punch press rail plate under the situation that but this structure is fast for mould speed, the anti-top of spring power big and work long hours.
Summary of the invention
The object of the present invention is to provide a kind of lever to approach the material shut-off mechanism, it can be good at solving thin problem of expecting that shut-off mechanism is big owing to fast, the anti-top of mould speed spring force, work long hours and cause cantilever bending to be out of shape in the prior art.
The objective of the invention is to realize through following technical scheme:
The thin material of a kind of lever shut-off mechanism, it comprises the cutting off tool that is installed on the lathe bed, the side top of said cutting off tool is provided with cantilever; Wherein, Said cutting off tool is provided with back-up block with respect to the opposite side that cantilever is set, and an end of making bar connects cantilever, and the other end is articulated on the back-up block; The said bar of beating hits rolling bearing in installing near the position of back-up block one end, and said strike rolling bearing contacts with strike cushion block on the upper slitter fixed head that is installed in cutting off tool.
Especially, an end of said cantilever is offered translot, makes bar and is assemblied in the translot through rolling bearing.
Especially, the quenching cushion block is set between said translot and the rolling bearing.
Especially, rolling bearing is installed in the said hinged place of playing bar and back-up block.
Especially, to be installed on apart from back-up block be on the position of 1/3 dozen of pole length to said strike rolling bearing.
Beneficial effect of the present invention does, the thin material of said lever shut-off mechanism drives and makes bar and move together when cantilever moves downward, and finally is in to hit rolling bearing and directly contact with the strike cushion block that is installed in the upper slitter fixed head, continues descendingly, and realization approaches expects cut-out; Directly acting on the upper slitter fixed head with the cantilever of prior art compares; Not only greatly the minimizing cantilever of degree directly acts on the destructive power that is produced, and long-time operate at high speeds effect is obvious, and beats between bar and cantilever and the back-up block rolling bearing is installed; During work; Rolling bearing back and forth rotates with the strike rolling bearing, avoids the surperficial wearing and tearing that work long hours, and improves service life.
Description of drawings
Fig. 1 is the thin structural representation of expecting shut-off mechanism of lever that the specific embodiment of the invention 1 provides;
Fig. 2 is the thin assembling sketch map of expecting shut-off mechanism of lever that the specific embodiment of the invention 1 provides.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through the specific embodiment.
See also shown in Figure 1ly, Fig. 1 is the structural representation of the thin material of the lever that provides of the specific embodiment of the invention 1 shut-off mechanism.
In the present embodiment; The thin material of a kind of lever shut-off mechanism comprises the cutting off tool that is installed on the lathe bed 1, and said cutting off tool comprises upper slitter fixed head 2 and following cutter fixed head 3, installs on the said upper slitter fixed head 2 and cuts off upper slitter 4; Install on the said cutter fixed head 3 down and cut off cutter 5 down; And a side of said cutting off tool top is provided with cantilever 6, is provided with back-up block 7 with respect to the cutting off tool opposite side that cantilever 6 is set, and an end of said cantilever 6 is offered translot 8; An end of making bar 9 is assemblied in the translot 8 through rolling bearing 10; Between said translot 8 and the rolling bearing 10 quenching cushion block 11 is set, the said other end of making bar 9 is articulated on the back-up block 7, and the said bar 9 of beating is installed rolling bearing 10 with the hinged place of back-up block 7.
The said bar 9 of beating is installed on the position that apart from back-up block 7 is 1/3 dozen of pole length and is hit rolling bearing 12, and said strike rolling bearing 12 contacts with strike cushion block 13 on the upper slitter fixed head 2 that is installed in cutting off tool.
See also shown in Figure 2ly, Fig. 2 is the assembling sketch map of the thin material of the lever that provides of the specific embodiment of the invention 1 shut-off mechanism.
During assembling; To organize the thin material of lever shut-off mechanism is installed on the lathe bed 1 more; And will connect the thin two ends of making bar 9 of expecting shut-off mechanism of every group of lever through guide rod 14; With every group independently the thin material of lever shut-off mechanism be assembled into a complete link gear, simultaneously with back-up block 7 with make bar 9 and be connected the location, and as an important fulcrum.Make bar 9 and move together when cantilever 6 moves downward to drive, finally to hit rolling bearing 12 and directly contact with the strike cushion block 13 that is installed in upper slitter fixed head 2, to continue descendingly, realization approaches expects cut-out; When cantilever 6 moves upward, under the effect of anti-top spring with upper slitter fixed head 2 along with cantilever 6 also moves upward, until cutting off upper slitter 4 and cutting off down cutter 5 and throws off the work completion fully.
The thin material of above-mentioned lever shut-off mechanism mainly satisfies increases work efficiency in process of production, avoids owing to anti-top spring force causes the cantilever bending distortion greatly, can't ordinary production.Specifically; In cantilever 6 and the joint of making bar 9, the joint playing the joint and the back-up block 7 of bar 9 and strike cushion block 13 and make bar 9 all installs rolling bearing 10, when the F1 that receives when strike rolling bearing 12 places reaches maximum, and the power of bearing in cantilever 6 places is about F2=1/2F1; Greatly the minimizing cantilever 6 of degree directly acts on the destructive power that is produced; Long-time operate at high speeds effect is obvious, and works as cantilever 6 and rise or descend, and drives rolling bearing 10 and back and forth rotates with strike rolling bearing 12; Avoid the surperficial wearing and tearing that work long hours, improve service life.
