[0003] In the prior art, the external grid of Chinese-style doors and windows is generally composed of an outer frame and hollow aluminum strips (square) welded into an irregular grid. Generally, the hollow aluminum strips need to be segmented and cut to fit different grid frames. However, the following problems exist when cutting the hollow aluminum strips: when cutting the hollow aluminum strips, the middle part of the hollow aluminum strip is in a hollow and unsupported state. At the initial cutting, due to the cutting pressure, after cutting the hollow aluminum strip, the middle position of the top of the fracture is prone to concave inward due to the lack of support force, resulting in that when the hollow aluminum strips are assembled and welded into a grid, secondary correction treatment is required to avoid unevenness at the welding joint affecting the welding quality, which is time-consuming and laborious, and greatly affects the production efficiency of the external grid.

[0020] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation manners.

[0021] As Figures 1 to 10As shown in the figure, a production and processing device for an external grille of Chinese-style doors and windows according to an embodiment of the present invention includes a workbench 1; a set of rotatably connected rollers 11 are provided on the workbench 1; fixed frames 12 are fixedly connected to both the upper surface and the lower surface of the workbench 1, and a cutting disc 14 is fixedly connected to the fixed frame 12 through a first hydraulic cylinder 13; a set of symmetrically distributed second hydraulic cylinders 15 are fixedly connected to the workbench 1 and on one side of the fixed frame 12, and an extrusion block 16 is fixedly connected to the end of each second hydraulic cylinder 15, and a first groove 17 is opened on the side wall of the extrusion block 16, and a roller 18 is rotatably connected in the first groove 17; symmetrically distributed moving blocks 2 are slidably connected to the workbench 1 and on the other side of the fixed frame 12, and a fixed block 21 is provided between the two moving blocks 2; a fixed rod 22 is fixedly connected to the side wall of the fixed block 21 close to the fixed frame 12, and an insertion block 23 is provided at the end of the fixed rod 22; a second groove 24 is opened on the side wall of the insertion block 23 close to the fixed rod 22; one end of the fixed rod 22 is inserted into the second groove 24, and both the fixed rod 22 and the second groove 24 are arranged in a T shape, the end of the fixed rod 22 is slidably connected in the second groove 24, and both the upper and lower surfaces of the fixed rod 22 located in the second groove 24 are fixedly connected to the upper and lower side walls of the second groove 24 through springs; an upper through groove 25 is opened on the upper side of the insertion block 23, and a lower through groove 26 is opened on the lower side of the insertion block 23; a pair of third grooves 27 symmetrically distributed with respect to the upper through groove 25 and the lower through groove 26 are respectively opened on the upper and lower sides of the insertion block 23; a fourth groove 28 is opened at the bottom of the third groove 27; a support plate 291 is placed in the third groove 27, and a micro hydraulic cylinder 29 is fixedly connected to the bottom of the fourth groove 28, and the micro hydraulic cylinder 29 is fixedly connected to the support plate 291 through a hydraulic rod; the end section of the insertion block 23 close to the fixed frame 12 is an isosceles trapezoid; the moving block 2 is moved by a power component; an extrusion component is provided on the workbench 1; in the prior art, the external grille of Chinese-style doors and windows is generally composed of a welded irregular grille by an outer frame and a hollow aluminum strip. Generally, the hollow aluminum strip needs to be segmented and cut to fit different grille frames. However, the following problems exist when the hollow aluminum strip is cut: when the hollow aluminum strip is cut, the middle part of the hollow aluminum strip is in a hollow and unsupported state. At the initial cutting, due to the cutting pressure, after the hollow aluminum strip is cut, the middle position of the top of the fracture is prone to concave inward due to the lack of support force, resulting in that when the hollow aluminum strip is assembled and welded into a grille, secondary correction treatment needs to be carried out to avoid unevenness at the welding joint affecting the welding quality, which is time-consuming and laborious, and greatly affects the production efficiency of the external grille;Therefore, when the present invention is in operation, the hollow aluminum strip is placed on the workbench 1, and the extrusion block 16 is used for extrusion and limiting. Then, an equidistant pusher in the prior art (such as the pushing of a manipulator, or a combination of a motor and a lead screw, etc., which is prior art and will not be specifically described) is used to push the hollow aluminum strip located on the workbench 1 forward. When it reaches the cutting position, at this time, the power member drives the moving block 2 to move, and then drives the fixed block 21 to move, so that the insertion block 23 connected to the fixed rod 22 is inserted into the hollow aluminum strip. Since the end cross-section of the insertion block 23 is arranged as an isosceles trapezoid, it can be conveniently inserted into the hollow aluminum strip (the length and width of the insertion block 23 are both smaller than the opening of the hollow aluminum strip). After insertion, first align the upper through groove 25 with the cutting position, and start the micro hydraulic cylinder 29 located on the top surface of the insertion block 23 to move the support plate 291 upward to support the upper cutting position. In the final state, the bottom end of the insertion block 23 fits on the inner bottom surface of the hollow aluminum strip, and the two upper support plates 291 fit on the inner top surface of the hollow aluminum strip. Then, start the first hydraulic cylinder 13 located above the workbench 1 to lower the cutting disc 14 (prior art, composed of a motor and a cutting blade) to cut the hollow aluminum strip in this state. Since the cutting blade of the cutting disc 14 is circular, when the lowest end of the cutting blade is about to fit on the bottom of the upper through groove 25, the cutting ends, completing the first step of cutting. After that, retract the support plate 291 at the top of the insertion block 23, and then push the moving block 2 and the fixed block 21 to move again through the power member, so that the lower through groove 26 of the insertion block 23 is located at the cutting position. Start the first hydraulic cylinder 13 located below the workbench 1 to move the cutting disc 14 upward to cut the hollow aluminum strip in this state, and cut off the hollow aluminum strip. The upper and lower cutting discs 14 are located on the same vertical plane. The power member can ensure that the moving positions of the lower through groove 26 and the upper through groove 25 correspond to each other, thereby ensuring the smoothness of the cutting surface. At the same time, when the cutting disc 14 is cutting, when the lowest end or the highest end of the cutting disc 14 is about to fit on the bottom surface of the upper through groove 25 and the lower through groove 26, the cutting disc 14 can cut a distance greater than half of the height of the hollow aluminum strip, so as to facilitate the cutting operation of the combination of the cutting discs 14 of the two fixing frames 12. Through the settings of the support plate 291, the upper through groove 25 and the lower through groove 26, during cutting, there can be supporting forces at the middle position of the top end of the cut hollow aluminum strip, which can greatly reduce the concave deformation caused by cutting and ensure the straight state of the cutting surface, facilitating the subsequent welding operation of the external grille (the parts in the attached drawing can be reduced in proportion, and this attached drawing is only for convenient viewing and understanding). Through the extrusion member, the hollow aluminum strip located on the workbench 1 can be fixed and limited to ensure the stability of the cutting disc 14 on the fixing frame 12 below the workbench 1 during cutting.;

[0022] The power component includes a first motor 35 and a lead screw 36; the lead screws 36 which are symmetrically distributed are rotatably connected on the workbench 1 and on the other side of the fixed frame 12; one side of the workbench 1 is fixedly connected with a first motor 35 through an L-shaped rod, and the output end of the first motor 35 is fixedly connected with the end of one of the lead screws 36; the pair of lead screws 36 are connected by a sprocket chain drive; both of the two moving blocks 2 are connected to the adjacent lead screw 36 through a lead screw nut pair; during operation, when it is necessary to push the insertion block 23 into the hollow aluminum strip, the first motor 35 is started at this time. The first motor 35 drives the pair of moving blocks 2 to move simultaneously through the lead screw 36 and the sprocket chain, thereby driving the fixed block 21 and the insertion block 23 to move. At the same time, the first motor 35 is a servo motor, which can accurately ensure the moving distance.

[0023] The fixed rod 22 includes a first connecting rod 3 and a second connecting rod 31; one end of the first connecting rod 3 is fixedly connected to the side wall of the fixed block 21; a fifth groove 32 is formed inside the first connecting rod 3; one end of the second connecting rod 31 is slidably connected in the fifth groove 32. One end of the second connecting rod 31 and the cross-section of the fifth groove 32 are both square. The other end of the second connecting rod 31 is T-shaped and is slidably connected in the second groove 24; a threaded groove 34 is formed inside one end of the second connecting rod 31 close to the fifth groove 32; a threaded rod 33 is threadedly connected in the threaded groove 34, and one end of the threaded rod 33 penetrates through the fixed block 21 and is rotatably connected to the fixed block 21; during operation, when it is necessary to cut hollow aluminum strips of different lengths and sizes, by rotating the threaded rod 33, the second connecting rod 31 is driven to move back and forth in the fifth groove 32. The cross-section of the second connecting rod 31 and the fifth groove 32 is square, and no deviation will occur. Then the length of the second connecting rod 31 is adjusted to be suitable for dividing hollow aluminum strips of different lengths and sizes.

[0024] Both ends of the fixed block 21 are rotationally connected to the corresponding moving block 2 through the second rotating shaft; a second motor 5 is fixedly connected to the side wall of the moving block 2, and the output end of the second motor 5 is connected to the second rotating shaft; a first through groove 4 is formed on the workbench 1 and on the other side of the fixed frame 12, and the first through groove 4 cuts off the roller 11 on the same side, and the fixed block 21 is located above the first through groove 4; a pair of symmetrically distributed first sliding grooves 41 are formed on one side of the bottom of the workbench 1, and a first sliding block 42 is slidably connected in each of the two first sliding grooves 41; a material discharging plate 43 is rotatably connected to the side walls of the pair of first sliding blocks 42 away from each other through a first rotating shaft, and the material discharging plate 43 is telescopic, and the cross section of the material discharging plate 43 is concave; during work, after the hollow aluminum strip is divided, the cut hollow aluminum strip is received by the inserting block 23 at this time. Therefore, the first through groove 4 is provided. After the hollow aluminum strip is cut, the first motor 35 is started at this time to drive the moving block 2 and the fixed block 21 to move backward, and then the second motor 5 is started. The second motor 5 drives the second rotating shaft to rotate, and then drives the fixed block 21 to rotate, so that the fixed block 21 is in an inclined state, and then the inserting block 23 and the hollow aluminum strip received by the inserted block 23 are in an inclined state, so that the hollow aluminum strip slides and is collected. Because the lengths of the cut hollow aluminum strips are different, the receiving positions of the material discharging plate 43 are different (the material discharging plate 43 slides through the first sliding block 42 and the first sliding groove 41 to adjust the position), which is convenient for the material collection operation.

[0025] Sixth grooves 51 are formed on the upper and lower surfaces of one end of the first connecting rod 3; a push plate 52 is slidably connected to the sixth groove 51, and the push plate 52 is fixedly connected to the side wall of the sixth groove 51 through a spring; a return plate 54 is provided on the side of the fixed block 21 away from the first connecting rod 3; a connecting column 53 is fixedly connected to the side wall of the push plate 52, and one end of the connecting column 53 passes through the first connecting rod 3 and the fixed block 21 and is fixedly connected to the side wall of the return plate 54; the return plate 54 moves back and forth through a pushing member; during work, due to the limited inclination angle, in order to ensure the detachment of the hollow aluminum strip, the sixth groove 51 is provided. When the fixed block 21 moves horizontally, the spring at the push plate 52 is in a compressed state. When the inserting block 23 is inserted, the upper through groove 25 is aligned with the cutting position. At this time, the end of the hollow aluminum strip is exactly at the end position of the first connecting rod 3. When the lower through groove 26 is adjusted to the cutting position, at this time, part of the end of the first connecting rod 3 and part of the sixth groove 51 extend into the hollow aluminum strip. After subsequent cutting, when the fixed block 21 is inclined by the second motor 5, the push plate 52 will be pushed by the pushing member at this time, so that the spring of the push plate 52 returns to its original state, and then the hollow aluminum strip that fails to detach from the inserting block 23 is pushed off, ensuring the collection of the hollow aluminum strip and avoiding affecting subsequent work.

[0026] The pushing member includes a first arc-shaped groove 55, a straight groove 56, and a second arc-shaped groove 57; the first arc-shaped grooves 55 are formed on the facing surfaces of a pair of moving blocks 2, and the centers of the first arc-shaped grooves 55 coincide with the center of the second rotating shaft; a straight groove 56 is formed at the end of the first arc-shaped groove 55, and the straight groove 56 is arranged towards the center of the first arc-shaped groove 55; a second arc-shaped groove 57 is formed between the end of the straight groove 56 close to the center of the first arc-shaped groove 55 and the end of the first arc-shaped groove 55 away from the straight groove 56; the first arc-shaped groove 55, the straight groove 56, and the second arc-shaped groove 57 are interconnected, the depths of the first arc-shaped groove 55 and the straight groove 56 are the same, the depth of the second arc-shaped groove 57 is lower than the depths of the first arc-shaped groove 55 and the straight groove 56, and a first arc-shaped inclined surface 591 is formed at the connection of the straight groove 56 and the second arc-shaped groove 57; seventh grooves 58 are formed on both side walls of the return-shaped plate 54; a pushing column 59 is fixedly connected to the bottom of the seventh groove 58 through a spring, the pushing column 59 is slidably connected to the seventh groove 58, and the two pushing columns 59 slide in the first arc-shaped groove 55, the straight groove 56, and the second arc-shaped groove 57 on the adjacent side respectively; during operation, when the fixed block 21 translates, at this time, the pushing columns 59 at both ends of the return-shaped plate 54 are located in the first arc-shaped groove 55. Since the depth of the second arc-shaped groove 57 is lower than that of the first arc-shaped groove 55, the springs at the push plate 52 are in a compressed state and will not be released at this time. When the fixed block 21 rotates, at this time, the return-shaped plate 54 rotates accordingly, and the pushing column 59 slides from one end of the first arc-shaped groove 55 to the other end. Since the other end of the first arc-shaped groove 55 is interconnected with the straight groove 56, at this time, the pushing column 59 will move in the straight groove 56, thereby enabling the springs on the push plate 52 to be instantly released, being able to instantaneously push the hollow aluminum strip that has not been separated, facilitating the separation of the hollow aluminum strip. At the same time, when the fixed block 21 returns to its original position, at this time, the pushing column 59 will enter the second arc-shaped groove 57 through the first arc-shaped inclined surface 591 at the straight groove 56 and the second arc-shaped groove 57, and enter the first arc-shaped groove 55 through the second arc-shaped groove 57, thereby enabling the return-shaped plate 54 to return to its original position, and at the same time enabling the springs of the push plate 52 to be in a compressed state.

When cutting is required, at this time, the third hydraulic cylinder 6 and the fourth hydraulic cylinder 61 drive the first squeezing plate 62 and the second squeezing plate 63 to fix and limit the hollow aluminum strip in the cutting state, ensuring the stability of cutting.

[0028] The upper pressing member includes a first push plate 7; the first push plate 7 is fixedly connected to the opposite surfaces of a pair of first pressing plates 62 through springs, and a first guiding column 71 is fixedly connected to the first push plate 7, and one end of the first guiding column 71 penetrates through the first pressing plate 62; a pair of second sliding grooves 72 symmetrically distributed with respect to the first push plate 7 are formed on the opposite surfaces of the pair of first pressing plates 62, and an upper pressing plate 73 is slidably connected in the second sliding groove 72, and the bottom of the upper pressing plate 73 is fixedly connected to the bottom wall of the second sliding groove 72 through a spring; a first inclined groove 75 is formed on the opposite surfaces of the pair of upper pressing plates 73; first sliding columns 74 are fixedly connected to both sides of the first push plate 7, and the first sliding columns 74 are slidably connected in the first inclined groove 75; during operation, when the first pressing plate 62 is pushed, the first push plate 7 first contacts the hollow aluminum strip, and then the first push plate 7 compresses the spring first. The movement of the first push plate 7 drives the upper pressing plate 73 to move downward through the first sliding columns 74 and the first inclined groove 75, thereby fixing the two sides of the hollow aluminum strip and limiting the downward pressure on the upper side.

[0029] The lower supporting member includes a second push plate 8; the second push plate 8 is fixedly connected to the opposite surfaces of a pair of second pressing plates 63 through springs, and a second guiding column 81 is fixedly connected to the second push plate 8, and one end of the second guiding column 81 penetrates through the second pressing plate 63; a pair of third sliding grooves 82 symmetrically distributed with respect to the second push plate 8 are formed on the opposite surfaces of the pair of second pressing plates 63, and a lower supporting plate 83 is slidably connected in the third sliding groove 82, and the lower supporting plate 83 is fixedly connected to the top end of the third sliding groove 82 through a spring; a second inclined groove 85 is formed on the opposite surfaces of the pair of lower supporting plates 83; second sliding columns 84 are fixedly connected to both sides of the second push plate 8, and the second sliding columns 84 are slidably connected in the second inclined groove 85; during operation, when the second pressing plate 63 is pushed, the second push plate 8 first contacts the hollow aluminum strip, and then the second push plate 8 compresses the spring first.

[0030] The moving block 2 is composed of an upper connecting block, a lower connecting block and a bolt connection. The lower connecting block is slidably connected to the side wall of the workbench 1, and the lower connecting block is connected to the lead screw 36 through a lead screw nut pair; the second motor 5, the fixed block 21, the first arc groove 55, the straight groove 56 and the second arc groove 57 are all arranged on the upper connecting block; during operation, when it is necessary to replace different insertion blocks 23 to correspond to the sizes of different hollow aluminum strips, the upper connecting block can be directly removed by screwing the bolt, and the replacement is simple and convenient.

[0031] Working principle: Place the hollow aluminum strip on the workbench 1, use the extrusion block 16 for extrusion and limit, and then use an equidistant pusher in the prior art (such as the push of a manipulator, or composed of a motor and a lead screw, etc., prior art, not specifically described) to push the hollow aluminum strip located on the workbench 1 forward. When it reaches the cutting position, at this time, the power component drives the moving block 2 to move, and then drives the fixed block 21 to move, so that the insertion block 23 connected to the fixed rod 22 is inserted into the hollow aluminum strip. Since the end cross-section of the insertion block 23 is set as an isosceles trapezoid, it is convenient to insert into the hollow aluminum strip (the length and width of the insertion block 23 are both smaller than the opening of the hollow aluminum strip). After insertion, first align the upper through groove 25 with the cutting position, and start the micro hydraulic cylinder 29 located on the top surface of the insertion block 23 to move the support plate 291 upward to support the upper cutting part. In the final state, the bottom end of the insertion block 23 fits on the inner bottom surface of the hollow aluminum strip, and the two upper support plates 291 fit on the inner top surface of the hollow aluminum strip. Then start the first hydraulic cylinder 13 above the workbench 1 to lower the cutting disc 14 (prior art, composed of a motor and a cutting blade) to cut the hollow aluminum strip in this state. Since the cutting blade of the cutting disc 14 is circular, when the lowest end of the cutting blade is about to fit on the bottom of the upper through groove 25, the cutting is completed, and the first step of cutting is completed. After that, retract the support plate 291 at the top of the insertion block 23, and then push the moving block 2 and the fixed block 21 to move again through the power component, so that the lower through groove 26 of the insertion block 23 is located at the cutting position. Start the first hydraulic cylinder 13 below the workbench 1 to raise the cutting disc 14 to cut the hollow aluminum strip in this state and cut off the hollow aluminum strip. The upper and lower cutting discs 14 are located on the same vertical plane. The power component can ensure that the moving positions of the lower through groove 26 and the upper through groove 25 correspond to each other, thereby ensuring the smoothness of the cutting surface. At the same time, when the cutting disc 14 is cutting, when the lowest end or the highest end of the cutting disc 14 is about to fit on the bottom surface of the upper through groove 25 and the lower through groove 26, the cutting disc 14 can cut a distance greater than half of the height of the hollow aluminum strip, so as to facilitate the cutting operation of the combination of the two cutting discs 14 of the fixed frame 12. Through the settings of the support plate 291, the upper through groove 25 and the lower through groove 26, during cutting, there can be a supporting force at the middle position of the top of the cut hollow aluminum strip, which can greatly reduce the concave deformation caused by cutting and ensure the flat state of the cutting surface, facilitating the subsequent welding operation of the external grille (the parts in the attached drawing can be scaled down proportionally, and this attached drawing is only for convenient viewing and understanding). The extrusion component can fix and limit the hollow aluminum strip located on the workbench 1 to ensure the stability of the cutting disc 14 on the fixed frame 12 below the workbench 1 during cutting;When the fixed block 21 translates, the push columns 59 at both ends of the paperclip-shaped plate 54 are located in the first arc-shaped groove 55 at this time. Since the depth of the second arc-shaped groove 57 is lower than that of the first arc-shaped groove 55, the spring at the push plate 52 is in a compressed state and will not be released at this time. When the fixed block 21 rotates, the paperclip-shaped plate 54 rotates accordingly, and the push column 59 slides from one end of the first arc-shaped groove 55 to the other end. Since the other end of the first arc-shaped groove 55 is in communication with the straight groove 56, the push column 59 will move in the straight groove 56 at this time, so that the spring on the push plate 52 is in an instant release state, which can instantaneously push the hollow aluminum strip that has not been separated, facilitating the separation of the hollow aluminum strip. At the same time, when the fixed block 21 returns to its original position, the push column 59 will enter the second arc-shaped groove 57 through the first arc-shaped inclined surface 591 at the straight groove 56 and the second arc-shaped groove 57, and then enter the first arc-shaped groove 55 through the second arc-shaped groove 57, so as to make the paperclip-shaped plate 54 return to its original position, and at the same time make the spring of the push plate 52 in a compressed state.;
