Description
Technical Field
The utility model relates to a cutter, concretely relates to be used for grooved cutter of cardboard.
Background
The cardboard for making the paper box or the cardboard box needs to be provided with grooves on the cardboard surface, and the cutter for forming the grooves of the cardboard is the cardboard grooving cutter. As shown in fig. 5, a general cardboard slotting cutter includes a cutter base and two blades, the cutter base has two opposite slots, the two blades are correspondingly installed in the two slots, the knife points of the two blades form a small space, and when the knife points of the two blades move along the cardboard surface, a groove can be formed on the cardboard. However, as shown in fig. 6, a plane 5 (a plane perpendicular to both the outer side surface and the inner side surface) is formed between the outer side surface and the inner side surface of the conventional insert, and the pocket of the tool holder is also a right-angle groove 6. When the blade cuts the paperboard, the reaction force of the blade on the paperboard is totally concentrated on the blade point, and the blade point is easily cut off.
In order to enable the tool tips of the two blades to form a small space, the two blades need to be adjusted, the tool adjustment method includes the steps of firstly placing one blade in one tool groove, then attaching a relatively long tool setting plate to the outer side face of the blade, then placing another blade in the other tool groove, adjusting the blade to enable the tool tips of the blades to be attached to the tool setting plate, then attaching the tool setting plate to the outer side face of the blade, finally returning to adjust the first blade to enable the tool tips of the first blade to be attached to the tool setting plate, and therefore the tool adjustment of the two blades is completed. However, when the existing blade is installed in the blade slot of the tool holder, the outer side surface of the blade slot can block the bottom ridge line of the blade, that is, the outer side protection block of the blade slot can block part of the outer side surface of the blade.
Disclosure of Invention
In view of the deficiencies in the prior art, the utility model discloses the innovation provides a cardboard slotting cutter that can improve blade durability.
The paperboard slotting cutter comprises a blade and a cutter holder, wherein the cutter holder is provided with a cutter groove for mounting the blade, an extension inclined plane is arranged between the outer side surface and the inner side surface of the blade, the cutter groove of the cutter holder is a V-shaped groove, the blade is detachably mounted in the V-shaped groove, the extension inclined plane of the blade acts on the outer supporting surface of the V-shaped groove, and the inner side surface of the blade acts on the inner supporting surface of the V-shaped groove.
The ridge between the extension inclined plane and the outer side face of the blade is located outside the V-shaped groove.
The blade holder has the briquetting, and the briquetting is located V type groove top, and threaded connection has the bolt on the blade holder, the briquetting can press on the blade through the bolt.
According to the utility model provides a pair of cardboard fluting cutter, its blade is difficult for collapsing the sword, and is more durable, and the tool setting is also more convenient moreover.

Detailed Description
As shown in fig. 1 to 3, the cardboard grooving tool includes a blade 1 and a tool holder 2, the tool holder 2 has a tool groove 20 for mounting the blade 1, and the blade 1 is mounted in the tool groove 20. As shown in fig. 2 and 3, an extension inclined surface 12 is provided between the outer side surface 10 and the inner side surface 11 of the utility model blade 1, an included angle formed between the extension inclined surface 12 and the inner side surface 11 is an acute angle, and an included angle formed between the extension inclined surface 12 and the outer side surface 10 is an obtuse angle. Because the blade 1 is provided with one more extension inclined surface 12, the stress at the point 14 of the blade 1 can be distributed on the extension inclined surface 12, thus greatly improving the durability of the blade 1.
Since the bottom of the insert 1 is beveled, the pocket 20 of the holder 2 is correspondingly V-shaped, as shown in fig. 4, the insert 1 is detachably mounted in the V-shaped groove, the extension bevel 13 of the insert 1 acts on the outer support surface 22 of the V-shaped groove, and the inner side surface 11 of the insert 1 acts on the inner support surface 21 of the V-shaped groove, and since the insert 1 has the extension bevel 13, the ridge 13 between the extension bevel 13 and the outer side surface 10 of the insert 1 can be located outside the V-shaped groove. Therefore, the outer side surface 10 of the blade 1 is not shielded (as shown in fig. 1), so that the blade can be directly attached to the outer side surface 10 of the blade 1 when the blade is subjected to blade setting, and the blade setting is very convenient.
Finally, it is worth mentioning that the tool post 2 has a pressing block 23, the pressing block 23 is located above the V-shaped groove, a bolt 24 is connected to the tool post 2 in a threaded manner, and the pressing block 23 can be pressed on the blade 1 through the bolt 24. After the position of the blade 1 is adjusted, the bolt 24 is screwed, the bolt 24 presses the pressing block 23 to move downwards, so that the pressing block 23 is pressed on the blade 1, and the blade 1 is firmly fixed in the cutter groove 20.
