Detailed description of the invention
With reference to Fig. 1, chamfer cutting mechanism for board material splice, including frame 1 and the chamfer cutting assembly that is installed in frame 1, chamfer cutting assembly is at least by cutting tool 2, cutting tool 2 is installed on movable carriage 3, described movable carriage 3 moves along sheet edge, and sheet edge is cut chamfering by cutting tool 2.Using cutting tool 2 to realize chamfer cutting by movable carriage 3, it is possible to ensure that otch flat smooth and machining accuracy are high, will not produce substantial amounts of processing airborne dust in the course of processing, cutting tool 2 is also not easy to produce abrasion.And movable carriage 3 translational speed is fast, it is possible to quickly realize two edges of sheet material quickly cuts chamfering, improves automated production degree and production efficiency.
For realizing the splicing spreading of indefinite length, the mode by sheet material head and the tail connect is needed constantly to splice, it is required for carrying out chamfer cutting at the head and the tail edge of splicing for this every block sheet material, the most described chamfer cutting assembly is two groups, it is respectively arranged on the both sides of sheet material, the upper surface of sheet edge is cut chamfering by one of which cutting tool 2, and the lower surface of sheet edge is cut chamfering by another group cutting tool 2.Synchronize during two groups of chamfer cutting component operation to carry out, namely can be respectively to completing while upper surface and lower surface to cut chamfering.Above the upper surface chamfering of sheet material and the lower surface chamfering of sheet material below are the most suitable, can complete splicing fixing after gluing pressing, and sheet material head and the tail splicing realizes the spreading of indefinite length successively.
Owing to material and the cutting position of sheet material are different, the sheet material etc. obtained near epidermal location processing such as timber, entirety may there is substantial amounts of gauffer in lamellar sheet material, such lamellar sheet material cuts chamfering and follow-up splicing by not completing.But in order to improve the utilization rate of timber to economize on resources, this utility model is provided with the clamping device for clamping sheet edge before cutting tool 2.Wherein clamping device is made up of the grip block 4 translated and drive mechanism, and drive mechanism drives grip block 4 upper and lower translation.When lamellar sheet material enters into the working range of chamfer cutting assembly, the lamellar sheet edge that needs are processed by drive mechanism driving grip block 4 clamp column tightly, under the effect of about 4 two planes of grip block, the edge of lamellar sheet material is realized leveling, also can ensure that the edge of lamellar sheet material is fixed in the course of processing firmly simultaneously, prevent moving influence machining accuracy.
For making the movement of movable carriage 3 complete chamfer cutting work, described frame 1 is provided with rail plate 5, and movable carriage 3 is installed on rail plate 5 translation.For completing the job demand of movable carriage 3 feed and withdrawing, described rail plate 5 being installed slide plate 6, movable carriage 3 is installed on slide plate 6 by horizontal translation mechanism 7, and horizontal translation mechanism 7 activity direction is vertical with rail plate 5.During work, when lamellar sheet material enters into the station of processing, first by clamping device, the edge of lamellar sheet material is firmly clamped and flattens, then horizontal translation mechanism 7 drives movable carriage 3 to realize feed, then slide plate 6 translates along rail plate 5 under the effect of drive mechanism, completes the chamfer cutting at edge, is driven movable carriage 3 to realize withdrawing by horizontal translation mechanism 7 the most again, clamping device separates and unclamps lamellar sheet material, cuts the lamellar sheet material after chamfering completes and is sent to the operation of assembled spreading.
Owing to different sheet material has different thickness requirements, needs are cut in order to meet the sheet material of different-thickness, improve machining accuracy, being provided with HeiFin mechanism 8 and the WidFin mechanism 9 of cascade in described movable carriage 3, cutting tool 2 is installed in HeiFin mechanism 8 and the WidFin mechanism 9 of cascade.By adjusting WidFin mechanism 9 and HeiFin mechanism 8 during debugging so that cutting tool 2 disclosure satisfy that the cutting needs of different size sheet material.
The specification of plywood is usually fixing, and the size of the most existing lamellar sheet material is the most relative normalized, and therefore the spacing between two groups of chamfer cutting assemblies is also relatively-stationary.But in order to enable mechanism to process the lamellar sheet material of some off-standard sizes, one of which chamfer cutting assembly can translate relative to another set chamfer cutting assembly, namely can adjust the spacing between two groups of chamfer cutting assemblies.The most also being the screw mandrel used and the structure of guide rail, one group of chamfer cutting assembly is arranged on guide rail, drives it to produce translation by screw mandrel, thus realizes the adjustment of spacing.
