Detailed Description

The following discloses many different embodiments or examples for implementing the subject technology described. Specific examples of components and arrangements are described below to simplify the present disclosure, but these are merely examples and do not limit the scope of the invention.

In addition, it is to be understood that references to "one embodiment", "an embodiment", and/or "some embodiments", "one or more embodiments" mean that a particular feature, structure, or characteristic described in connection with at least one embodiment of the application is intended. Therefore, it is emphasized and should be appreciated that two or more references to "an embodiment" or "one embodiment" or "some embodiments" or "one or more embodiments" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, some features, structures, or characteristics of one or more embodiments of the present application may be combined as appropriate.

In the following, a cutting device, a production line and a cutting method thereof will be described by taking a window frame as an example.

Referring to fig. 7, the manufacturing line 100 for door and window frames includes a drawing device 20, a collecting device 30, and a cutting device 10, the drawing device 20 being located upstream of the cutting device 10 for drawing the raw material strip 200 to move in a first direction D1, and the collecting device 30 being located downstream of the cutting device 10 for drawing the cut raw material strip 300 to move in the first direction and collecting and packing it.

Referring to fig. 1-4, in some embodiments, the cutting device 10 may include a first cutting saw 1, a second cutting saw 2, and a table assembly 3. As shown in fig. 1, the cutting device 10 may include a protective cover 4 covering the first cutting saw 1, the second cutting saw 2, and the work table assembly 3 to improve safety of work, prevent waste generated from cutting from flying out, and prevent generated powder from affecting health of an operator.

The table assembly 3 includes a table top 31, a base 32 supporting the table top 31, and a clamp 33, the clamp 33 being used to clamp the strip of stock material 200 stationary relative to the table for cutting. The clamp 33 may include a first clamp 331 and a second clamp 332 as shown in fig. 2 to 4, and the first clamp 331, the first dicing saw 1, the second dicing saw 2, and the second clamp 332 are sequentially disposed in the first direction, and for example, as shown in fig. 2 to 4, the first clamp 331 and the second clamp 332 are respectively disposed at both ends of the work top 31. As shown in fig. 2 and 4, the work top 31 and the base 32 may be connected by a rail mechanism 51 so that the work top 31 and the base 32 move in a first direction relative to each other. When cutting is performed, the work table 31 can be moved from one end of the work table assembly 3 to the other end by the material strip under the traction force of the traction device 20 in the first direction, and when cutting is completed, the work table can be moved from the other end to the one end of the work table assembly by the air cylinder 52, so that the structure of the work table 31 can be compact, and the material strip can be stably fixed. It will be appreciated that the work surface 31 may also be non-moving, for example the work surface itself extending from one end of the work table assembly to the other. As shown in fig. 2 to 4, the first clamping member 331 and the second clamping member 332 may be driven by the first air cylinder 3311 and the second air cylinder 3321, respectively, and move from top to bottom to press the raw material strip against the work table 31, but not limited thereto, for example, a clamping member may be provided on one side of the work table, and the clamping member located on the work table moves from bottom to top during clamping and works together with the clamping member moving from top to bottom to clamp the raw material strip at a position having a certain height from the work table 31. By adopting the scheme shown in the figure, the operation table surface 31 has good supporting effect on the raw material strips, so that the raw material strips are stable in position and small in jumping amount during cutting, and the cutting precision of the raw material strips is high. The cylinder 11 may drive the first cutting saw 1 to move from top to bottom to the cutting position, and the cylinder 21 may drive the second cutting saw 2 to move from bottom to top to the cutting position, but not limited thereto.

Referring to fig. 2 to 4, the first and

second dicing saws

1 and 2 are mounted at positions separated by the work surface 31 on both sides of the work surface 31. As shown in fig. 3, the table top 31 may be a horizontal plane, that is, in the XYZ coordinate system shown in fig. 4, the table top 31 belongs to an XY plane, the first cutting saw 1 and the second cutting saw 2 are respectively located on both sides of the Z-axis direction of the table top 31, that is, the mounting position P1 of the first cutting saw 1 is located on the upper side of the table top 31, and the mounting position P2 of the second cutting saw 2 is located on the lower side of the table top. When the first cutting saw 1 cuts, the first cutting saw 1 moves from the mounting position P1 to the top down (i.e. along the negative Z-axis direction) to cut the raw material strip, and when the second cutting saw 2 cuts, the second cutting saw 2 moves from the mounting position P1 to the top down (i.e. along the positive Z-axis direction) to cut the raw material strip. It is understood that the moving direction of the cutting saw is not limited to the above description, for example, the table top may belong to YZ plane, the mounting positions of the first cutting saw and the second cutting saw are respectively located on two sides of the table top in the X axis direction and are separated by the table top, when the first cutting saw 1 performs cutting, the first cutting saw 1 moves from the mounting position to the raw material strip along the X axis positive direction for cutting, and when the second cutting saw 2 performs cutting, the second cutting saw 2 moves from the mounting position to the raw material strip along the X axis negative direction for cutting. The embodiment of fig. 2 to 4 is adopted, the cutting precision is better, and the principle may be that the gravity action of the raw material strip itself can be utilized to make the raw material strip have the tendency of being stable on the operation table surface when cutting, so that the raw material strip is more stable when cutting. As shown in fig. 2 and 4, because the door and window frames generally need to be spliced, the cutting angle of the dicing saw is generally non-right, for example, 45 ° is commonly used, as shown in fig. 2, the cutting angle of the first dicing saw 1, that is, the included angle between the cutting angle of the first dicing saw and the straight line extending from the raw material strip is 45 °, the cutting angle of the second dicing saw 2, and the included angle between the cutting angle of the second dicing saw and the straight line extending from the raw material strip is-45 °, and the included angle between the cutting angle of the first dicing saw and. It can be understood that, if the raw material strip does not need to be cut into the frame capable of being directly spliced, but only the raw material strip is simply cut off by a certain length, at the moment, the first cutting saw 1 or the second cutting saw 2 can be remounted, so that the cutting angle of the first cutting saw or the second cutting saw 2 is a right angle, when the raw material strip is cut off, the first clamping piece 331 and the second clamping piece 332 clamp the raw material strip, one of the first cutting saw 1 or the second cutting saw 2 is moved to the raw material strip for cutting, and the other one of the first cutting saw 1 and the second cutting saw 2 is located at the installation position of the first cutting saw or the second cutting saw. The structure and method for reinstalling the cutting saw, for example, the first cutting saw 1 is reinstalled, as shown in fig. 2, the first cutting saw 1 is rotated by 45 ° through a rotating shaft 41 installed on the work table 31 until the cutting angle is a right angle, locked by a latch 42, and detected to be in place by a sensor 43.

The advantage of using the work table 31 to separate the first and

second dicing saws

1 and 2 will be more apparent from the explanation of fig. 5 and 6. As shown in fig. 6, the cutting method of cutting the raw material strip 200 to obtain the window frame may be:

first knife: the first clamping piece 331 at the front end and the second clamping piece 332 at the rear end are both clamping structures, at this time, the first cutting saw 1 is located at the installation position, the second cutting saw 2 moves from the installation position to the cutting position from bottom to top to cut the raw material strip 200, and after the cutting, the second clamping piece 332 is released, so that the cut initial waste material 500 is driven by the collecting device 30 to move continuously along the first direction to leave the cutting device, the length of the initial waste material 500 may be long, for example, the cutting device 10 may be integrated with a forming device into the same production line, and the initial waste material 500 of the raw material strip may be a defective product obtained due to process adjustment in the forming process. It will be appreciated that the mounting position described above is one of the non-cutting positions of the dicing saw.

A second knife: bearing on the above, the first clamping piece 331 still keeps the clamping structure, the second clamping piece 332 is the loosening structure, the first cutting saw 1 moves from the mounting position to the cutting position from top to bottom to cut the raw material strip 200, the second cutting saw 2 moves from the mounting position to cut the waste material 400, the size of the waste material 400 is small, a waste material slot can be formed in the operation table top 31, so that the waste material 400 falls to a special collecting container from the waste material slot, the waste material 400 is prevented from being sorted by the collecting device 30, and the production steps of the door and window frame are simplified.

The third knife, the first clamping piece 331 and the second clamping piece 332 are both of a loosening structure, at this time, the raw material strip 200 is continuously moved along the first direction under the action of the traction force of the traction device 20, after the first length L is moved, the first clamping piece 331 and the second clamping piece 332 are switched to a clamping structure, the second cutting saw 2 is moved from the bottom to the top of the installation position of the second cutting saw to the cutting position to cut the raw material strip 200, the broken raw material strip 300 with the length of the first length L is obtained, the second clamping piece 332 is loosened after cutting, the raw material strip 300 is a product, is driven by the collecting device 30, is moved along the first direction, and is collected and packaged by the collecting device 30;

a fourth knife: as described above, the first clamping member 331 is still in the clamping configuration, the second clamping member 332 is in the releasing configuration, the first cutting saw 1 moves from the mounting position to the cutting position from the top to the bottom to cut the raw material strip 200, and the second cutting saw 2 is in the mounting position to cut the scrap 400.

The action of the fifth knife is the same as that of the third knife, the action of the sixth knife is the same as that of the fourth knife, and so on. A batch of window frames of the first length L is thus obtained. It will be appreciated that the length of movement of the material strip 200 in different steps may be controlled to obtain sash bars of different lengths, for example, two long and two wide sash bars of rectangular window frames are cut separately in the process, and every four sash bars are collected in groups in the collecting device 30, and each group of window frame bars is collected in a group that can be spliced in real time.

The inventors found that since the window frame requires the installation of the window frame to be installed at the outside of a wall and the installation of the glass at the inside of the window frame, the inside structure has some grooves compared to the outside structure, and thus, the structural sectional shape of the window frame is asymmetrical, and the scrap 400 is inevitably generated during the cutting process. The first cutting saw and the second cutting saw are arranged on the two sides of the operation table respectively, so that the problem of installation interference of the first cutting saw and the second cutting saw is not needed to be considered, the first cutting saw and the second cutting saw can be close to each other in the first direction, the size of the waste material 400 is reduced as much as possible, the material waste in the cutting process is greatly reduced, and the material cost is reduced. Meanwhile, under the condition that the first clamping piece 331 is in a clamping structure and the second clamping piece 332 is in a loosening structure, the first cutting saw 1 is used for cutting from top to bottom at the moment, and the beneficial effects are achieved by the inventor that under the condition that the stationary phase of the raw material strip is not stable enough for the condition that the two clamping pieces are in the clamping structure, the first cutting saw 1 is used for cutting from top to bottom in accordance with the gravity direction, and compared with the condition that the second cutting saw is used for cutting from bottom to top, the raw material strip is more stable, the jumping during cutting is smaller, and the cutting precision is higher.

It will be appreciated that the sequence of the first, second, third and fourth knives … … shown in fig. 6, the first and second knives, may also be directly merged into the second knife in fig. 6, but the control is simpler with the cutting sequence shown in fig. 6.

In summary, the door and window frame cutting device, the production line and the cutting method introduced in the above embodiments have the beneficial effects that, by respectively arranging the first cutting saw and the second cutting saw on the two sides of the raw material strip, the waste material section of the raw material strip generated in the cutting process is very short, the material waste in the cutting process is greatly reduced, and the material cost is reduced; meanwhile, compared with manual cutting, automatic cutting provides production efficiency and reduces time cost of a cutting process.

For example, a cutting apparatus, a production line, and a cutting method are used for cutting a door frame.
