Abstract

The utility model discloses a can shrink back and cut base sword aims at providing one kind and is applicable to the cutting that contains hard thing base strip, and its technical scheme's main points are: by the locating support with can around the cutter frame that shifts make up and form, the locating support is outside and in the back, including the cutter frame and in the front, paste with the front and back depended wheel who installs on the locating support respectively mutually the horizontal both sides of the back end left and right sides in the cutter frame, two piece longitudinal extension screw rods in the both sides, telescopic screw rod front end top meets with cutter frame horizontal pole, the rear end is passed from the horizontal dagger plank of locating support, telescopic screw rod outer fringe cover between horizontal pole and the dagger plank is equipped with the spring, the back telescopic screw rod of dagger plank of being separated by with the spring goes up the nut for screwing. Its acting principle does: the cutter frame is obstructed and retreats when running into hard thing in the cutting, back the spring compressed of this moment, the cutter of in operation frame and base strip after -separating, the extension masterpiece by compression spring under with the antedisplacement restore to the throne.

Description

One can be shunk back and be cut base cutter

Technical field

The utility model relate to brick and tile enterprise aborning with main frame and the supporting a kind of accessory machinery of extruder, be more definitely more particularly used to continuously base bar on-stream extruded for main frame to cut into again one of them spare and accessory parts---the cutting knife of a kind of cutting machine of monolithic adobe or unbaked tile.

Background technology

Select with blade cut base cutter for cut its structure of base with acting principle as depicted in figs. 1 and 2, wherein Fig. 1 is the corresponding vertical extruder of vertical installation, and Fig. 2 is that flat installs corresponding flat extruder.In Fig. 1: be manyly linked as an annular ring cutting base cutter 7 by the connecting plate 25 of back and travelling wheel 8 and minor axis 10, upper and lower two is linked on each runner 9, adjacent two to cut its junction of base cutter be a travelling wheel 8, its acting principle is: from the machine mouth 1 of vertical extruder, squeezed base bar 6 out promotes in vertical decline that left and right is many to be synchronously shifted cutting knife 7 from the top down, slope track 3 and impel under being arranged on little axle 10 travelling wheel 8 acting in conjunction many cutting knife 7 from top to bottom and from the superficial to the deep simultaneously and constant speed implement to cut to base bar 6, relative two cutting knifes 7 in left and right are respectively from outer toward Nei Geqie 1/2nd, become adobe after base bar is cut off to fall within for 2 times on the next conveyer belt 4 and seen off.Base bar is that initiatively cutting knife is that passive belt connects runner 9 and rotates by the direction of arrow 5, and in rotation, each travelling wheel 8 straight rail road 3 from the top down and inwardly slippage, realizes being in the many of Inner limit (near base bar for interior) thus and cutting knife is ceaselessly participated in cutting; In fig. 2: the base bar 11 that its machine mouth 1 of extruder of flat installation is on-stream extruded shifts forward with horizontal on endless-belt 4, endless-belt is supported by multiple carrying roller 12 and is located, each carrying roller 12 two is arranged in support (not shown), the cutting knife group of single strip ring is arranged on the top of its base bar 11, the cycloconveyor belt 23 that the adobe 2 be split is driven by power is seen off, change into except unidirectional cutting except two-way to cutting, its structure is identical with Fig. 1 with acting principle.

Because above-mentioned its structure of base cutter of cutting is one overall, be therefore only applicable to the base bar of cutting without hard object such as impure i.e. handstones, just there will be when meeting hard object and cut the distortion of base cutter or by the drawback fractureed.

invention Inner holds

The utility model is for overcoming above-mentioned deficiency, and aim to provide and a kind ofly cutting the technical scheme can not damaged in base process and cut base cutter, specific practice is as follows.

By cut base cutter by locating support with can before and after the cutoff knife rack that is shifted combined, locating support is outside and rear, cutoff knife rack is interior and front, the horizontal left and right sides, cutoff knife rack posterior segment is affixed with the front and back roller be arranged on locating support respectively, two longitudinal extension screw rods in both sides, top, expansion screw front end connects with cross bar, rear end is passed from the horizontal dagger plank of locating support, expansion screw outer rim between cross bar and dagger plank is set with spring, with nut on the expansion screw of the dagger plank back be separated by with spring, cutoff knife rack front is provided with blade, blade cutting edge of a knife or a sword mouth two is separately installed with up and down according to base bar width or claims left and right each roller.

Its acting principle is: in lower cutter cutting, when running into hard object, such as stone or ironware are obstructed, elastic force due to spring is limited and impel cutoff knife rack to retreat, spring is now compressed, operate after to lower dead center or its cutoff knife rack of front stop, in retrogressing, its front edge of a knife and base bar are thrown off, resistance is now eliminated, former form by Compress Spring stretching force effect incision knife rest to move forward immediately reset, its result is appearance one even base (not cutting off), there is no damage to blade.The roller role installed additional be by base bar through blade cuts time the otch burr that occur flatten, make it have more aesthetic feeling, its reason is cutting edge its roller synchronous rotary thereupon in displacement from the superficial to the deep.

Described on end, its main points of technical scheme selected by the utility model are: cut base cutter by locating support with can before and after the cutoff knife rack that is shifted combined, locating support is outside and rear, cutoff knife rack is interior and front, left and right, cutoff knife rack posterior segment both lateral sides is affixed with the front and back roller be arranged on locating support respectively, two longitudinal extension screw rods in both sides, top, expansion screw front end connects with cutoff knife rack cross bar, rear end is passed from the horizontal dagger plank of locating support, expansion screw outer rim between cross bar and dagger plank is set with spring, nut for screwing on the expansion screw of the dagger plank back be separated by with spring.Blade cutting edge of a knife or a sword mouth two is separately installed with up and down according to base bar width or claims left and right each roller.

The beneficial effects of the utility model can not damage when running into hard object to cut base cutter in cutting process, and therefore the scope of application broadens, and the Strong degree of spring can be determined according to the hardness of base bar, namely when being as the criterion by property cut without during hard object in base bar; Besides due to the existence of roller, the burr formed in cutting process are driven plain in the rolling by roller and have more aesthetic feeling.
