Description

Cut a machine cut-off knife by knife system

Technical field

The utility model relates to a kind of device of cutting a machine, refers to that especially a kind of machine cut-off knife of cutting is by knife system.

Background technology

An existing machine of cutting is to utilize cutter to cooperate bottom knife to produce the effect that cuts in platform, for the sharpness that cuts between the blade is increased, be provided with in bottom knife or cutter place can forward and backward adjustment location gap tool setting structure, the adjustment of gap tool setting structure makes the tip of cutter be able to align with the tip of bottom knife by this, so can produce the preferable effect that cuts in staggered.

Though the aforementioned existing gap tool setting structure of cutting a machine can reach and promote the effect that cuts effect, but owing to be to reach with the means of the forward and backward position of screw lock adjustment blade, the process that fixture such as quick-release bolt is locked again when adjusting is except consuming time, adjustment between the aligned blades also is not easy to carry out, and therefore causes and adjusts consuming time and difficult shortcoming.

The utility model content

Because both gapped tool setting device was to adjust spacing between cutter and the bottom knife in the mode of screw lock, therefore causes and adjust consuming time and difficult shortcoming.For this reason, the utility model forms by the cutter extension in cutter one end, cooperates to lean on the promotion of cutter pneumatic cylinder to reach really by the effect of cutter by the means that the cutter extension leans bottom knife again, saves the time of correction and adjustment tool setting, reaches to cut effect fast and accurately.

For achieving the above object, the utility model provides a kind of machine cut-off knife of cutting by knife system, comprising:

One body structure, be to be provided with relative biside plate in the left and right position, bridge joint tool rest once between the biside plate inner face, in conjunction with a bottom knife, the front end in the bottom knife top forms blade in the apical margin that descends the tool rest front, the position of corresponding bottom knife top, between biside plate, form one and wear mouth, to wearing the trailing edge of mouth, respectively set firmly a linear slide rail seat in the outside of each side plate, in the front of each linear slide rail seat one linear slide rail is set vertically; And

One cut-off knife structure, be to be provided with a upper cutter head in the top of bottom knife, its and arranged on left and right sides respectively is provided with a side arm, passing this with two side arms wears the both sides of mouth and is incorporated into each linear slide rail respectively, the position at the left and right both ends of the corresponding upper cutter head back first half, form with left and right interval is extended two pivot connecting plates backwards respectively in the upper cutter head back, between each is to pivot connecting plate with can forward and backward rotation form in conjunction with a suspension gear, wear a plurality of holes that place in the bottom of upper cutter head with left and right equally spaced form again;

Back in the upper cutter head bottom is provided with a upper tool post, its front in the bottom is arranged with a cutter caulking groove, left side in the upper tool post end face, each extends an extension board up right both sides, be incorporated into each suspension gear with each extension board, in the cutter caulking groove in conjunction with a cutter, form a upper knife edge in the bottom of cutter, again in a cutter left side, the right two ends wherein bottom of an end extend to form one down by the cutter extension, should align with the tip of upper knife edge by the back of cutter extension, and be resisted against down the tip of blade backwards, place one by the cutter pneumatic cylinder in respectively placing the hole, it is stretched backwards and establishes a fore-set, with the front of each fore-set against upper tool post.

Further, the utility model respectively forms a recess in the left and right both ends of the described upper cutter head back first half, forward-facing runs through forming a window in each recess interior, described each to corresponding each the window and arranged on left and right sides of pivot connecting plate, extend in the interior backward-facing of this recess.

Further, the utility model in described each wear a pivot hole between to pivot connecting plate; Described each suspension gear is provided with a swinging block between each is to pivot connecting plate, between the left and right two sides at each swinging block top, laterally run through a perforation, place a pivot between each perforation to the pivot hole of pivot connecting plate and each swinging block, two extension boards of described upper tool post are incorporated into two swinging blocks.

Further, the utility model is arranged with a storage tank in the bottom surface of described each swinging block, each storage tank is the groove of horizontal expansion, the position of corresponding each storage tank, before each swinging block, centre between the back two sides and a left side, right both sides respectively wear a pin hole and two positioning screw holes, described each extension board stretches in each storage tank, the position of corresponding each pin hole, wear latch perforation in each extension board, place a location latch between each pin hole and each latch perforation that cooperates, again before each positioning screw hole, back two ends are screw lock one location bolt respectively, in the past, the inner of each bolt of back both sides be resisted against each extension board before, urgent location, back two sides.

When the utility model uses, cut pull bar by the two side arms that is incorporated into down upper cutter head up with two, cut pull bar with two and connect the driving structure that is arranged at the body structure below in addition, reach with upper cutter head drop-down or on push away the effect that resets.When the utility model cuts, be that article to be cut are placed between cutter and the bottom knife, then together move down to cut pull bar pulling upper cutter head, upper tool post and cutter, cooperate bottom knife will wait to cut the article severing with cutter, the cutter extension that leans on owing to cutter in the process closely leans the following blade of bottom knife, therefore when the upper knife edge incision of cutter, can cut, reach the preferable effect that cuts along the following blade of bottom knife.

Because the utility model is the effect that the application of force is provided by each fore-set by the cutter pneumatic cylinder by the strength that the cutter extension leans down blade, the structure that cooperates upper tool post to be articulated in upper cutter head and can swing through suspension gear, make between cutter and the bottom knife and need not forward and backward adjustment can reach lasting by the cutter effect, and can set different according to the different material fit that cuts by cutter pressure, the utility model is easy to use and effect is certain by knife system, has splendid result of use.
