The utility model provides a shoveling and cutting knife and a knife rest thereof. The shoveling and cutting knife comprises a blade point formed by an upper diagonal plane and a lower diagonal plane; the middle part of theupper diagonal plane is not beveled, and a lug boss is formed relative to the upper diagonal plane; and the outer end of the lug boss is a smooth arc surface and extends out of the blade point. The shoveling and cutting knife rest comprises a square column-shaped arm part and a triangular table-shaped palm part; and the lower end face of the palm part is providedwith two threaded holes for fixing the shoveling and cutting knife. The shoveling and cutting knife is suitable for shoveling and cutting the end part of a raised rib of a strip workpiece, has high shoveling and cutting accuracy and high working performance, and is particularly suitable for shoveling and cutting the end part of the raised rib of an automotive decoration strip.

Description

Shovel cutting knife and knife rest thereof

Technical field

The utility model relates to a kind of shovel cutting knife and knife rest thereof.

Background technology

Often need to shovel some strip-shaped works on engineering and cut operation; Traditional shovel cutting knife as shown in Figure 8, and is similar with the planing tool in traditional carpenter's plane.

Fig. 1, workpiece shown in Figure 2 are a kind of decorating strip for automobile that needs the end shovel to cut, this has two by the convex tendon A that be symmetric of PVC material through the continuous extruding technological forming above ornamental strip, because ornamental strip self installation needs, the convex tendon A that is positioned at the end of ornamental strip needs excision, after General Requirements excision with two convex tendon A between PVC organize B to flush, even requiring of having organized B lower than the PVC between two convex tendon A; The shovel cut before as shown in Figure 1, the shovel cut after as shown in Figure 2.Cut as shoveling with as shown in Figure 8 traditional cutting knife, be difficult to avoid to be organized B also cut by the PVC that shovel is cut between its two convex tendon A.

The utility model is head it off just.

Summary of the invention

Technical problem to be solved in the utility model is for the above-mentioned state of the art, and a kind of shovel cutting knife and knife rest thereof are provided.

The utility model solves the problems of the technologies described above the technical scheme that adopts:

A kind of shovel cutting knife comprises the knife edge mouth that is formed by upper scarf and lower scarf, it is characterized in that, the pars intermedia of described upper scarf is not chamfered, and relatively goes up scarf and forms boss, and the outer end of this boss is smooth arc surface, and stretches out in knife edge mouth.

Described shovel cutting knife is rectangle sheet thing, and its thickness is 5mm to 10mm.

Described shovel cutting knife thickness is 6mm to 7mm.

Described shovel cutting knife is provided with 2 installing holes.

Described installing hole is slot, along described shovel cutting knife longitudinal centre line and column distribution.

The shovel cutoff knife rack of above-mentioned shovel cutting knife is installed, it is characterized in that, described shovel cutoff knife rack comprises the arm of flat column and the metacarpus of triangle table shape, and the lower surface of metacarpus is provided with 2 screwed holes that are used for fixing shovel cutting knife.

The side of described arm is provided with 2 and is used for himself hard-wired kidney-shaped through hole.

The upper surface of described arm also is provided with 1 screwed hole.

The utility model shovel cutting knife and knife rest thereof are fit to that the strip-shaped work raised ribs is carried out the end shovel and cut, and shovel cuts that precision is high, and shovel is cut having stable behavior, and operating efficiency is high; The raised ribs of especially suitable automotive trim strip is carried out the end shovel and is cut.

The specific embodiment

As shown in Figure 3, Figure 4, the utility model shovel cutting knife comprises the knife edge mouth 4 that is formed by upper scarf 2 and lower scarf 3, the pars intermedia of upper scarf 2 is not chamfered, relatively go up scarf 2 and form boss 5, the outer end 6 of this boss 5 is smooth arc surface, and stretches out in knife edge mouth 4.The shovel cutting knife is rectangle sheet thing, and its thickness a is 5mm to 10mm, is preferably 6mm to 7mm.Shovel cutting knife 1 is provided with 2 installing holes 7, and installing hole 7 is advisable with slot, can be along shovel cutting knife 1 longitudinal centre line and column distribution.This boss 5 is set, and its outer end 6 is smooth arc surface, when 2 parallel convex tendon operations of shovel cut spare, can effectively avoid between two convex tendons should not be cut by the part that shovel is cut.

The utility model, also provide and shovel the shovel cutoff knife rack 8 of cutting operation after being fit to install this shovel cutting knife, as Fig. 5, Figure 6 shows that the shovel cutoff knife rack 8 that the utility model shovel cutting knife is installed, this shovel cutoff knife rack 8 comprises the arm 9 of flat column and the metacarpus 10 of triangle table shape, and the lower surface of metacarpus 10 is provided with 2 screwed holes 11 that are used for fixing shovel cutting knife 1.The side of arm 9 is provided with 2 and is used for himself hard-wired kidney-shaped through hole 12.The upper surface of arm 9 also is provided with 1 screwed hole 13.

Workpiece is a kind of decorating strip for automobile 14 that needs the end shovel to cut as shown in Figure 1 and Figure 2, this has two by the convex tendon A that be symmetric of PVC material through the continuous extruding technological forming above ornamental strip 14, because ornamental strip 14 self is installed needs, the convex tendon A that is positioned at the end of ornamental strip needs excision; The shovel cut before as shown in Figure 1, the shovel cut after as shown in Figure 2.Below take this ornamental strip as workpiece in conjunction with as shown in Figure 7 strip-shaped work end shovel cutting apparatus explanation purposes of the present utility model and benefit, this device is equipped with the utility model shovel cutting knife 1 and knife rest 8 thereof.

Strip-shaped work end shovel cutting apparatus as shown in Figure 7 comprises clamp mechanism and shovel cutting mechanism, and shovel is cut front decoration bar 14 and clamped by clamp mechanism; The shovel cutting mechanism comprises the cantilever beam 16 that is driven by cylinder 15; The shovel cutoff knife rack 8 of the utility model shovel cutting knife 1 is installed through 2 kidney-shaped through holes 12 of the side of its arm 9, be fixedly mounted on the most end end face of cantilever beam 16, the upper surface of its arm 9 through its screwed hole 13 with add the briquetting 17 that is located at above cantilever beam 16 ends and be connected, add pad both, the plus-minus spacer thickness can be regulated the height and position of shovel cutoff knife rack 8.Shovel cutoff knife rack 8 drives by cylinder 15 shovel of completing the convex tendon A of ornamental strip 14 ends and cuts action.when shovel is cut, owing to not being chamfered at the pars intermedia that shovels scarf 2 on cutting knife 1, form boss 5 but relatively go up scarf 2, this boss 5 can be avoided when workpiece ornamental strip shovel is cut operation effectively should not be cut by shovel by the PVC tissue that shovel is cut between its two convex tendon A, even should not be organized higher than knife edge mouth position by the PVC that shovel is cut between its two convex tendon A, effect due to the smooth arc surface outer end 6 of boss 5, the B that should not be organized by the PVC that shovel is cut between its two convex tendon A only can be subjected to its smooth arc surface outer end 6 crimps, and can not cut by shovel.
