The stripping spring is in mobile connection with the tool axis; both sides of the rotation arm are provided with a tool holder respectively; a locking device is mounted between the tool holder and the rotation arm; a punching tool is mounted at the lower end of the tool holder; a location device is mounted between the punching tool and the tool holder; the location centre goes beyond the punching cutter point. The paperboard punching tool realizes the punching mechanization, which improves the punching efficiency and precision greatly. And the operation of the paperboard punching tool is very convenient.
Description
Technical field
The utility model relates to a kind of perforating cutting tool to cardboard perforatings such as honeycomb cardboard, corrugated boards.
Background technology
In the past, honeycomb cardboard was not a very prosperous industry always, and the scale of the enterprise in this industry is all smaller usually, demand to honeycomb cardboard is also very little, it all is hand labour basically that the postorder processing of honeycomb cardboard is handled, and labour intensity is big, and production efficiency is not high.In fact, because little to total demand of honeycomb paper, the amount of each batch is pitiably little especially, and the requirement that makes the postorder processing of honeycomb cardboard handle mechanization is not very urgent.Yet, along with the fast development of China's economy and country pay attention to day by day, obtained fast development as the honeycomb cardboard industry of ep-type material for environmental protection, a lot of manual operationss originally all or by mechanization produce substitute.But, up to the present, the hole knockout of honeycomb cardboard is not improved, still be done manually; The limit, hole of getting is more crude, and the precision in aperture also can not get good assurance.
The utility model content
Technical problem to be solved in the utility model is: a kind of efficient height, drilling precision height are provided, and can change the cardboard perforating cutting tool of the diameter that punches.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: cardboard perforating cutting tool, comprise: cutter shaft, be equipped with pivoted arm in the cutter shaft, the bottom of cutter shaft is provided with the location thimble and takes off the material spring, takes off material spring and cutter shaft and flexibly connects, the both sides of pivoted arm are respectively arranged with knife rest, be provided with locking device between knife rest and the pivoted arm, the lower end of knife rest is provided with the punching cutter, is provided with positioner between punching cutter and the knife rest; Described location thimble exceeds punching cutter point of a knife.
The both sides of above-mentioned pivoted arm are provided with the graduation mark that cooperatively interacts.
The above-mentioned knife rest and the set-up mode of pivoted arm are: described pivoted arm is a cuboid, offers the pilot hole that matches with pivoted arm in the knife rest, and pivoted arm is located in the pilot hole; The concrete structure of the locking device between above-mentioned knife rest and the pivoted arm is: offer the locking hole that communicates with pilot hole at the top of described knife rest, be provided with clamping screw in the locking hole; Above-mentioned knife rest with the concrete structure of the positioner between the cutter that punches is: the lower end of knife rest is provided with the installing hole that matches with the cutter handle of a knife that punches, and also is provided with the locating hole that communicates with installing hole on the sidewall of knife rest, is provided with bolt in the locating hole.
The beneficial effects of the utility model are: by the rotation of cutter shaft, the punching cutter that drives pivoted arm and be arranged on the pivoted arm both sides rotates together, can realize easily the mechanization of punching making the efficient and the precision of punching all be greatly enhanced.In addition, this perforating cutting tool can also be regulated the diameter of punching, gets the hole of various different sizes.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1, cutter shaft, 11, square cotter, 2, pivoted arm, 3, knife rest, 4, clamping screw, 5, bolt, 6, the punching cutter, 7, the location thimble, 8, take off the material spring, 9, plane bearing, 10, graduation mark.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1, cardboard perforating cutting tool described in the utility model, comprise: cutter shaft 1, be equipped with pivoted arm 2 in the cutter shaft 1, pivoted arm 2 fixedly connected with cutter shaft 1 and pivoted arm 2 along the axial line left-right symmetry of cutter shaft 1, the bottom of cutter shaft 1 is provided with location thimble 7 and takes off material spring 8, taking off material spring 8 flexibly connects by plane bearing 9 and cutter shaft 1, the both sides of pivoted arm 2 are respectively arranged with knife rest 3, its concrete structure is: described pivoted arm 2 is cuboid, offer the pilot hole that matches with pivoted arm 2 in the knife rest 3, pivoted arm 2 is located in the pilot hole of knife rest 3; The top of knife rest 3 offers the locking hole that communicates with pilot hole, is provided with in the locking hole knife rest 3 is locked in clamping screw 4 on the pivoted arm 2; The lower end of knife rest 3 is provided with the installing hole that matches with the handle of a knife of the cutter 6 that punches, the handle of a knife of punching cutter 6 is arranged in the installing hole of knife rest 3 lower ends, also be provided with the locating hole that communicates with installing hole on the sidewall of knife rest 3, be provided with handle of a knife with punching cutter 6 in the locating hole and be fixed on bolt 5 in the installing hole of knife rest 3 lower ends; Described location thimble 7 exceeds punching cutter 6 points of a knife.In the present embodiment, the both sides of described pivoted arm 2 are provided with the graduation mark that cooperatively interacts.
During use, square cotter on the cutter shaft 1 11 and rotating mechanism are connect, finish punching by the relative motion of cardboard and perforating cutting tool to cardboard, here just rising to example with paper advance mechanism drive cardboard is described: the handle of a knife of punching cutter 6 is installed in the installing hole of knife rest 3 lower ends, and screwed in place bolt 5, according to the punching diameter, indication according to graduation mark 10, left and right symmetrically is determined the position of knife rest 3 on pivoted arm 2, make the distance between two punching cuttves 6 adapt, tighten clamping screw 4 then, knife rest 3 is fixed on the pivoted arm 2 with the punching diameter; Connect power supply, by the time punch and can put into cardboard after cutter 6 at the uniform velocity rotates, the rising cardboard, the location thimble 7 of cutter shaft 1 lower end at first contacts with cardboard and inserts in the cardboard, so just guarantee cardboard hole heart non-migration in punching, made drilling precision well be ensured; Continuous rising along with cardboard, taking off material spring 8 constantly is compressed, progressively increase the top power of paper loading plate, so just avoided cardboard and punching to be unfavorable for the vibrations of punching between the cutter 6, cardboard continues to rise, 6 beginnings of punching cutter contact and cut in the cardboard with cardboard, according to desired trajectory cardboard is cut, when punching cutter 6 is cut when wearing cardboard, cardboard no longer rises, the strain of taking off material spring 8 also reaches maximum, and the circular hole slab that is cut breaks away from location thimble 7 and falls to scrap heap under the effect of elastic force; Paper advance mechanism is got back to initial position, and whole punching process finishes.
Use the utility model, can realize easily the mechanization of punching making the efficient of punching and precision all obtain significantly improving, operate also very simple.In addition, this perforating cutting tool is regulated the punching diameter, replacing punching cutter 6 is all very convenient; And many perforating cutting tools can be used in combination, once get a plurality of holes, further improve the efficient of punching.
