The auxiliary pressing device 47 is disposed on the incoming side of the cutting saw 3, and is also implemented by using an elastic pressing wheel structure similar to the feeding driving device 4, and the difference is that the pressing wheel is only auxiliary pressing and does not need to be equipped with a power device.
The cutting method of the L-shaped wood strip 9 cutting equipment comprises the following steps.
The method comprises the following steps: obtaining master batch 5 which can be cut into m L-shaped wood strips 9, wherein the master batch 5 comprises a master batch top surface 51, a master batch bottom surface 52, a master batch left surface 53 and a master batch right surface 54, namely the master batch 5 is cut into wood with a rectangular cross section; the distance between the master batch top surface 51 and the master batch bottom surface 52 is the sum of the outer length of one L-shaped batten 9 and the thickness of the short side of the L-shaped batten 9. In this embodiment, m is an even number, m L-shaped battens 9 are typeset on the master batch 5 as shown in fig. 1, and m is 8 in this embodiment; the distance between the left side 53 of the master batch and the right side 54 of the master batch is the outer width of the L-shaped batten 9 multiplied by m/2, and the thickness of the long side of the L-shaped batten 9 is added.
Taking the left surface 53 of the master batch as a reference, sequentially cutting a plurality of top surface dividing lines 55 after spacing a distance of the inner width of the L-shaped batten 9 on the top surface 51 of the master batch, wherein the distance between two adjacent top surface dividing lines 55 is the outer width of the L-shaped batten 9, and the depth of each top surface dividing line 55 is the inner length of one L-shaped batten 9; on the basis of the left surface 53 of the master batch, after an outer width distance of an L-shaped batten 9 is spaced on the bottom surface 52 of the master batch, a plurality of bottom surface dividing lines 56 are sequentially cut, the distance between every two adjacent bottom surface dividing lines 56 is the outer width of the L-shaped batten 9, and the depth of each bottom surface dividing line 56 is the inner length of the L-shaped batten 9. The top surface dividing lines 55 and the bottom surface dividing lines 56 are cut to form a staggered arrangement, as shown in fig. 2.
Since the m is an even number, the top dividing lines 55 and the bottom dividing lines 56 have the same number and the same pitch, the top dividing lines 55 can be formed by cutting with a plurality of saw blades arranged at equal pitches at a time, and the bottom dividing lines 56 have the same structure, so that the processing of the top dividing lines 55 and the bottom dividing lines 56 is greatly simplified, and the processing efficiency is improved. Of course, the top dividing line 55 and the bottom dividing line 56 are not limited to be cut by a plurality of saw blades at a time, and may be cut by one saw blade in sequence for a plurality of times.
Step two: the master batch 5 is placed on the cutting table 1 by the master batch bottom surface 52 and placed on the side guide surface 21 by the master batch left surface 53, and the master batch 5 is driven to feed and cut towards the cutting saw 3; after cutting, the first scrap 57 is cut from the master batch 5, and an L-shaped notch 58 is formed in the master batch 5.
Step three: and turning the cut master batch 5 by 180 degrees, so that the top surface 51 of the master batch is abutted against the cutting table 1, the vertical edge of the L-shaped notch 58 is abutted against the side guide surface 21, the transverse edge of the L-shaped notch 58 is positioned at the top guide surface 22, and the master batch 5 is driven to feed and cut to the cutting saw 3. Since the height difference between the top guide surface 22 and the cutting table 1 is preferably equal to the outer length of the L-shaped wood strip 9 in this embodiment, the top guide surface 22 also plays a role in supporting and guiding the transverse edge of the L-shaped slot 58, and the feeding driving wheel 42 can perform more stable twisting feeding.
In addition, in this embodiment, the guide table 2 is provided with two side guide surfaces 21 symmetrically arranged, a top guide surface 22 is respectively arranged above each side guide surface 21, and two sides of the dicing saw 3 are respectively extended from the two side guide surfaces 21. Based on the above arrangement, the 180 ° of the master batch 5 in step three is turned by 180 ° in the left-right direction, that is, from the state of fig. 5 to the state of fig. 9. Of course, if only one of the side guide surfaces 21 is provided in the present embodiment, the 180 ° turned over master batch 5 here is turned 180 ° in pitch in the feed direction, and after turning over, feed cutting can likewise be performed with the various seating and abutting positions described above.
After cutting, an L-shaped batten 9 is cut off from the master batch 5, and a new L-shaped notch 58 is formed in the master batch 5.
Step four: and turning the cut master batch 5 for 180 degrees again, so that the master batch bottom surface 52 is located on the cutting table 1, the vertical edge of the new L-shaped notch 58 is abutted against the side guide surface 21, the transverse edge of the new L-shaped notch 58 is located on the top guide surface 22, and the master batch 5 is driven to feed and cut to the cutting saw 3. Here, the 180 ° turn is also the 180 ° left-right turn, i.e., the state from fig. 9 to fig. 11.
After cutting, an L-shaped batten 9 is cut on the master batch 5, and a new L-shaped notch 58 is formed on the master batch 5;
step five: and the third step and the fourth step are carried out in a circulating way, namely, a plurality of L-shaped wood strips 9 can be cut in sequence until the last L-shaped wood strip 9 is cut, as shown in fig. 13.
Preferably, the following steps are further included between step two and step three: as shown in fig. 7, the master batch 5 is driven to feed and cut towards the cutting saw 3 by seating the master batch bottom surface 52 on the cutting table 1 and abutting the master batch right surface 54 against the side guide surface 21; after cutting, a second scrap 59 is cut from the master batch 5. Thus, the second scrap 59, which is originally left after the last cutting, is cut out in advance, and only two L-shaped wood strips 9 are left for cutting in the end of the step five, as shown in fig. 13. The final cutting of the second waste 59 is avoided, and the feed drive is guaranteed to be stable in the whole cutting process.
In the embodiment, the cross section of the master batch 5 is reasonably typeset, and the cutting method is improved, so that one master batch 5 can sequentially cut m L-shaped battens 9, the m L-shaped battens 9 can be cut out only by generating less waste, the wood utilization rate can reach more than 85%, and compared with the traditional L-shaped batten 9 cutting, the wood utilization rate can be improved by about 20%, and the wood utilization rate is obviously improved. The width of the master batch 5 can be flexibly changed according to the number of the cut m, and based on the method, the master batch 5 can be flexibly cut according to the available wood resources, for example, the master batch 5 capable of cutting out eight L-shaped battens 9 can be cut out preferentially, then the leftover materials are cut and utilized according to the master batch 5 capable of cutting out four, six or ten L-shaped battens 9 in the residual leftover materials of the wood resources, so that the full utilization of the wood resources can be ensured, and the higher utilization rate of the wood can be ensured.
Most of the tail ends of the cutting lines cut by the cutting saw 3 are positioned at the inner side of the L-shaped battens 9, the outer side surfaces of the battens are not easy to have the defects of cutting marks and the like which influence the appearance, and the finished product rate is high. Since the top surface dividing line 55 and the bottom surface dividing line 56 both relate to the inner long side of one L-shaped batten 9 and the short side end surface of the adjacent L-shaped batten 9, the cutting apparatus and the cutting method of the present embodiment are particularly suitable for the cutting operation of the L-shaped battens 9 with the same long side thickness and inner width. Because the distance between the rightmost bottom dividing line 56 and the right master batch surface 54 in the first step is also the inner width of the L-shaped batten 9, the top dividing line 55 and the bottom dividing line 56 are in central symmetry on the master batch 5, so that after the top dividing line 55 is processed, the master batch 5 is turned over by 180 ° leftwards or rightwards, and the cutting of the bottom dividing line 56 can be completed immediately by the reference and the saw blade when the top dividing line 55 is cut, thereby further simplifying the processing and further improving the processing efficiency.
The whole cutting process of this embodiment location is convenient, and processing is simple, and the order of m L shape stuff 9 is surely gone out, has also reduced the frequency of cutting by a wide margin, and machining efficiency is high.
Example two: as shown in fig. 16, the present embodiment is different from the first embodiment in that: in this embodiment, m is an odd number, and the distance between the left side 53 of the master batch and the right side 54 of the master batch is (m + 1)/2 multiplied by the outer length of one L-shaped batten 9. The sequential cutting of the L-shaped strips 9 can still be achieved by this cutting method according to the first embodiment, but the second scrap 59 can also be cut off in advance before the sequential cutting of the L-shaped strips 9. Through the mode, the typesetting of the master batch 5 is more flexible, the application range is further widened, and the wood utilization rate is ensured.
Example three: as shown in fig. 17, the present embodiment is different from the first embodiment in that: in this embodiment, the feeding driving wheel 42 is arranged towards the oblique feeding driving of the guide table 2, so that the feeding driving wheel 42 drives the master batch 5 to feed, and simultaneously, the master batch 5 is automatically given with a force of being attached to the side guide surface 21, so that the master batch 5 is prevented from being fed and deviated under the condition of reducing manual auxiliary operation, accurate cutting is ensured, and the operation safety is improved.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
