Abstract

The utility model belongs to the technical field of machinery and particularly provides a cutting mechanism for coiled materials in order to solve the technical problem that the cutting operation on the coiled materials is inconvenient, time-costing and labor-consuming. The cutting mechanism comprises a cutter shaft, a locking screw, a cutter unit and an arc-shaped slit, wherein the arc-shaped slit is arranged on the cutter shaft in a way that the cutter shaft is surrounded by the entire arc-shaped slit; the arc-shaped slit comprises a fixed end and a free end, the fixed end of the arc-shaped slit is arranged on the cutter shaft, and the free end thereof is extended out between the cutter unit and the cutter shaft; and the free end of the arc-shaped slit is under the direct action of the locking screw, so as to fix the cutter unit and the cutter shaft. The cutting mechanism of the utility model has the advantage of convenient and time-saving cutting operation and improves the operating efficiency.

Description

A kind of cutting mechanism of coiled material

Technical field

The utility model belongs to field of mechanical technique, relates to a kind of cutting mechanism of coiled material, particularly a kind of cutting mechanism of drum band.

Background technology

When some similar drum art papers, drum sheet metal strip or other drum materials are cut, need a kind of special cutting tool to cut, arrived the purpose of different demands, the different in width that forms after the processing after cutting, the plate-like product of different-diameter directly are widely used in various fields such as press, decoration field, transformer manufacturing industry, air-conditioner manufacturing industry, cables manufacturing industry and building decoration, food and drink packing.

Because present cutting mechanism almost is original frame for movement, cutter directly is welded on the cutter shaft, or adopts common butterfly blade, the cutter axial dimension is big, cutting edge is thin, the width size can not be controlled, and the cutter poor radiation, and service life is short, and the cutter that is used to cut is after working for a long time, meeting is turned or edge of a knife interlock is not tight, causes the coiled material of cutting not meet the requirements, and causes the waste or the loss of coiled material.Its cutter trimming or adjustment operation easier are big, and non-cutting time is long, wastes time and energy.

Summary of the invention

The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of dismountable, cutter and has cut that width can be controlled and the coiled material cutting mechanism of blade long service life.

The purpose of this utility model can realize by following technical proposal: a kind of coiled material cutting mechanism is characterized in that: comprise cutter shaft, lock-screw, cutting knife unit and arcuate slots; Described arcuate slots integral loop is around being arranged on the cutter shaft; Described arcuate slots comprises stiff end and free end; The stiff end of described arcuate slots is arranged on the cutter shaft; The free end of described arcuate slots is stretched between cutting knife unit and the cutter shaft; Described lock-screw directly acts on the arcuate slots free end cutting knife unit and cutter shaft is fixed.

In above-mentioned coiled material cutting mechanism, described cutting knife unit comprises push type broach screw, blade, knife rest; Described blade is an annular; Described knife rest is concentric rotary structure; Described blade is fixed on the knife rest by the push type broach screw.

In above-mentioned coiled material cutting mechanism, described cutter shaft is two; Cutting knife unit on the described cutter shaft is a plurality of; The corresponding coherent of the blade of a plurality of cutting knifes unit of fixing separately on described two cutter shafts connects.

In above-mentioned coiled material cutting mechanism, described knife rest is around being arranged on the cutter shaft.

Compared with prior art, the utility model adopts the cutter structure of adjustable movable knife rest, and cutter for same tool changing, toolsetting operation easier are reduced greatly, makes significantly shorten non-cutting time simultaneously; In addition, the utility model make cutter for same can the scope of cutting can precisely control and detachably, strong, the long service life of thermal diffusivity.

Description of drawings

Fig. 1 is the partial structurtes schematic diagram of the utility model cutting mechanism;

Fig. 2 is that the A of Fig. 1 is to view.

Among the figure, 1, cutter shaft; 2, push type broach screw; 3, blade; 4, knife rest; 5, lock-screw; 6, arcuate slots.

The specific embodiment

Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.

As depicted in figs. 1 and 2, this coiled material cutting mechanism, this coiled material cutting mechanism can carry out longitudinal shear and becomes some fillets entering wherein view picture volume type band, this cutting mechanism is made up of cutter shaft 1, push type broach screw 2, blade 3, knife rest 4 and lock-screw 5, shown in cutter shaft 1 have two, be the rigid rotating axle, installation is parallel to each other, knife rest 4 has several, be concentric rotary structure, as shown in Figure 2, uniformly near the end face the heart portion endoporus have three arcuate slots 6, one end of arcuate slots 6 all communicates with endoporus, form uniform three single-ended unsettled tongue-shaped.Be installed on the axial plane of two cutter shafts 1 by pore size distribution in its heart portion; Blade 3 its quantity are identical with knife rest 4, it is shaped as annular, section is a rectangle, the corner angle of both sides are the shearing edge of a knife on its cylindrical, be evenly equipped with some screw counter bores on the end face, by push type broach screw 2 with itself and the knife rest 3 fastening cover cutting knife unit that are connected into, some cover cutting knifes unit on two cutter shafts 1 is distributed as corresponding one by one the arrangement on axial plane, and the blade 3 cutting edge coherents on each cutting knife unit are connect, again with trip bolt 5 uniform on each cutting knife unit by inwardly pressing three uniform on the knife rest 4 unsettled tongue pieces, each cutting knife unit is held tightly with cutter shaft 1 to be connected, constitute some groups of shearing edges, when view picture volume type band from the shearing edge of cutting mechanism through out-of-date, drive each cutting knife units synchronization and roll in opposite directions, just realized the continuous longitudinal shear of cutting mechanism to the view picture sheet metal strip, very easy to use.

Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.

Although this paper has used 1, cutter shaft morely; 2, push type broach screw; 3, blade; 4, knife rest; 5, lock-screw; 6, term such as arcuate slots, but do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
