Description

Technical Field

[0001] The present invention relates to the technical field of sawing machines, and particularly relates to a sawing machine and method for processing wooden molds based on the construction of an arc-shaped roof. Background Art

[0002] The saw teeth are a disc and an endless saw band. The endless saw band is tensioned on two saw wheels, and the saw band is driven by the saw wheels to perform cutting. Band sawing machines mainly have two types: vertical and horizontal. The saw frame of the vertical band sawing machine is vertically arranged. During cutting, the workpiece moves to cut the curve profiles of sheet materials and formed parts. The saw band can also be replaced with a file chain or a sand belt for filing or grinding. When processing an arc-shaped wooden mold, the wood needs to be softened by steam treatment in advance to reduce the brittleness of the wood, and then cutting is carried out. After cutting, the plate is bent and formed.

[0003] A woodworking sawing machine disclosed in the patent application with the reference publication number CN113954178A includes a base, a circular saw, a first vertical plate, a second vertical plate, a support plate and a support plate support frame; wherein, the first vertical plate and the second vertical plate are vertically arranged on the base, and the first vertical plate and the second vertical plate are arranged at intervals and in parallel; the circular saw is arranged at one end in the horizontal direction of the second vertical plate, and the circular saw is arranged on the side of the second vertical plate away from the first vertical plate; the saw blade of the circular saw is horizontally arranged, and the saw blade passes through the first vertical plate and the second vertical plate; the support plate is arranged between the first vertical plate and the second vertical plate for supporting the material to be cut, and the support plate is connected to the first vertical plate through a plurality of the support plate support frames, and the positions of the support plate support frames in the height direction of the first vertical plate are adjustable. This woodworking sawing machine is convenient for cutting wood or templates, has convenient operation during cutting, high cutting accuracy, and good safety, and is suitable for popularization and use.

[0004] The above solution adjusts and fixes the wood through an adjusting device. During the processing of an arc-shaped wooden mold, the wood is softened by steam and then cut. However, during the cutting process, if the humidity inside the board is too high, it may cause cracking or deformation due to uneven moisture content during subsequent bending. At the same time, during the cutting process, the humidity exceeds the standard, causing the wood to soften, and burrs and tears are easily generated during sawing. After cutting, subsequent processing by equipment is still required, affecting the overall processing of the wooden mold.

[0005] Therefore, it is necessary to provide a sawing machine and method for processing wooden molds based on the construction of an arc-shaped roof to solve the above technical problems. Summary of the Invention

[0020] A method for processing wooden molds based on the construction of an arched roof includes the following steps:

[0021] Step 1: Place the softened board on the top of the placement plate by means of a steam softening process, fix the board through the clamping assembly, and perform two cuts on the set cutting distance through the cutting device;

[0022] Step 2: After the first cut is completed, start the first hydraulic rod to make the contact member contact the top of the board. Then, drive the board to retreat through the moving device. The contact member drives the detection mechanism to descend to one side of the board cut surface, and the detection mechanism detects the humidity at the board cut surface.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. Locally heat the part of the cut surface with excessive humidity through the dehumidification mechanism. When the humidity reaches the standard, perform the final cutting and forming. By means of secondary cutting, first cut the front part, and then detect the humidity of the cut surface after cutting through the detection mechanism. When the humidity is too high, process its local humidity through the dehumidification mechanism, so as to ensure the humidity inside the board, and then perform cutting, thereby overcoming the influence caused by too high humidity and ensuring the processing of the subsequent arched wooden mold.

[0026] 2. The humidity sensors on multiple connecting shafts move equidistantly, so as to adjust according to the boards of different thicknesses, enabling the multiple humidity sensors to detect the humidity at different positions of the board. The humidity sensor can be a non-contact microwave humidity sensor. And as the contact member contacts different thickness positions of the board, the upper fixing plate also rises and adjusts along with the lifting plate, which can be adaptively adjusted. When it is detected that the humidity exceeds the specified value, then start the dehumidification mechanism to heat its position and adjust its humidity.

[0027] 3. The electromagnet ring drives the sealing plate inside the connecting cylinder through magnetic attraction. When the bottom plate of the contact member comes into contact, the electromagnet ring stops moving. At this time, it drives the sealing plate to move to the position corresponding to the thickness of the plate, and the sealing plate seals the upper part of the connecting cylinder, so that the hot air inside the connecting cylinder can be discharged through some air outlet holes, thus enabling humidity control for plates of different thicknesses.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0043] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating orientation or positional relationships are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.

[0044] As Figures 1 to 12 shown, a sawing machine and method for wood mold processing based on the construction of an arc-shaped roof include the following embodiments:

[0045] Embodiment 1: As Figures 1 to 5 shown, it includes a platform 1, a sawing machine frame 101 is fixedly installed on the outside of the platform 1, a cutting device 102 for cutting is arranged on the outside of the sawing machine frame 101, and further includes:

[0046] A placing plate 2 for placing plates, a clamping assembly for fixing the plates is arranged on the top of the placing plate 2, and a moving device 201 for moving the placing plate 2 is arranged on the top of the platform 1;

[0047] The first hydraulic rod 301 is arranged above the platform 1. The telescopic end of the first hydraulic rod 301 is fixedly connected with a connecting plate 3. A contact member that contacts the cut plate is arranged at the bottom of the connecting plate 3, and a touch switch 402 is arranged outside the contact member.

[0048] The lifting plate 5 is fixedly connected to the outside of the contact member. A detection mechanism for detecting the humidity of the wood cutting surface is arranged at the bottom of the lifting plate 5. A metal plate 611 is arranged at the bottom of the detection mechanism. A connecting column 6012 is fixed to the top of the platform 1, and an electromagnetic iron plate 6013 is fixedly connected to the top of the connecting column 6012. After the electromagnetic iron plate 6013 is electrified, it magnetically adsorbs to the metal plate 611.

[0049] A fixing frame 8 is fixedly connected to the top of the placing plate 2. A dehumidification component for dehumidifying the plate is arranged inside the fixing frame 8. An adjusting member is arranged between the lifting plate 5 and the dehumidification mechanism for dehumidifying plates of different thicknesses.

[0050] During specific implementation, in the process of processing wooden molds for the construction of an arc-shaped roof, the wood bending process needs to ensure that the moisture content is between 20% and 30% of the fiber saturation point during the softening stage to reduce strength and improve plasticity. The steam softening process for the plate needs to be at a temperature of 90 - 100 °C for 2 - 4 hours to reduce the brittleness of the wood and enhance the bending plasticity, and to avoid cracking caused by stress concentration during cutting. If the plate is cut without knowing the humidity inside the plate at this time, it may cause cracking or deformation due to uneven moisture content during subsequent bending. At the same time, during the cutting process, if the humidity exceeds the standard, the wood will soften, and burrs and tears are likely to occur during sawing, and the surface roughness increases compared to normal plates, affecting the subsequent splicing accuracy. Therefore, in this solution, the softened plate after the steam softening process is placed on the top of the placing plate 2, and the plate is fixed by the clamping assembly, and the cutting device 102 performs two cuts at a set cutting distance. After the first cut is completed, by starting the first hydraulic rod 301, the contact member contacts the top of the plate, and then the moving device 201 drives the plate to retreat. The contact member drives the detection mechanism to descend to one side of the plate cut surface, and the detection mechanism detects the humidity at the plate cut surface. When the detected humidity exceeds the preset value, the dehumidification mechanism locally heats the part of the cut surface with excessive humidity. When the humidity reaches the standard, the final cutting and forming are performed. By means of secondary cutting, the front position is cut first, and then the detection mechanism detects the humidity of the cut surface after cutting. When the humidity is too high, the dehumidification mechanism processes its local humidity, so as to ensure the humidity inside the plate, and then perform cutting, thereby overcoming the influence caused by too high humidity and ensuring the processing of the subsequent arc-shaped wooden mold.

[0051] In this embodiment, as Figure 2 and Figure 12As shown in the figure, the clamping assembly includes two clamping seats 202. On one side of each of the two clamping seats 202, a first electric telescopic rod 203 is fixedly connected. The telescopic end of the first electric telescopic rod 203 is fixedly connected to a second electric telescopic rod 204. One of the clamping seats 202 is fixedly connected to the placement plate 2, and the other clamping seat 202 is slidably connected to the top of the placement plate 2. A driving lead screw 205 is arranged on the top of the placement plate 2. The driving lead screw 205 passes through the clamping seat 202 and is connected to the clamping seat 202 through a ball screw pair. A driving motor is fixedly connected to the top of the placement plate 2, and the output shaft of the driving motor is fixedly connected to the driving lead screw 205.

[0052] The contact member includes a contact frame 4. The contact frame 4 is fixedly connected to the lifting plate 5. A first telescopic rod 403 and a first spring 404 are fixedly connected between the contact frame 4 and the connecting plate 3. The first spring 404 is sleeved outside the first telescopic rod 403. A contact wheel 401 is rotatably connected to the bottom of the contact frame 4. A touch switch 402 is fixedly connected to the bottom of the contact frame 4, and the touch switch 402 is kept horizontal with the contact wheel 401.

[0053] During specific implementation, when a sheet is placed on the top of the placement plate 2, by starting the first electric telescopic rod 203, the telescopic end of the first electric telescopic rod 203 pushes the second electric telescopic rod 204, and the telescopic end of the second electric telescopic rod 204 descends to fix the upper part of the sheet. At the same time, the position of the other clamping seat 202 can be adjusted according to the length of the sheet, so as to adjust the clamping of sheets of different sizes. And the moving device 201 can be driven by a lead screw module, which will not be elaborated further here. In order to ensure the control of the cutting distance of the sheet, an electric push rod can also be arranged on one side of the clamping seat 202 to push the sheet to move and adjust the cutting position;

[0054] After the first cutting, the first hydraulic rod 301 pushes the connecting plate 3 to descend. The connecting plate 3 pushes the contact frame 4 to descend through the first spring 404 and the first telescopic rod 403, so that the touch switch 402 at the bottom of the contact frame 4 contacts the sheet, and at the same time, the contact wheel 401 contacts the sheet.

[0055] Embodiment 2: As Figures 4 to 6As shown in the figure, the detection mechanism includes an upper fixing plate 601 and a lower fixing plate 602. A first rotating shaft 604 is rotatably connected to the opposite sides of the upper fixing plate 601 and the lower fixing plate 602. Two first hinged rods 603 are rotatably connected to the outer sides of the two first rotating shafts 604. A plurality of second hinged rods 605 are rotatably connected between the two first hinged rods 603 on the opposite sides. The plurality of second hinged rods 605 are rotatably connected end to end, and each two second hinged rods 605 are rotatably connected by a connecting shaft 606 arranged therebetween. Humidity sensors 607 for detecting humidity are fixedly connected to the outer sides of the plurality of connecting shafts 606. A metal plate 611 is fixedly connected to the bottom of the lower fixing plate 602. The metal plate 611 is electrically connected to the touch switch 402. An elastic member is arranged between the lower fixing plate 602 and the upper fixing plate 601 for pulling the lower fixing plate 602 to rise.

[0056] During specific implementation, when the sheet cutting is completed, the moving device 201 is started to drive the placing plate 2 to retract. At this time, the first hydraulic rod 301 is started, and the upper connecting plate 3 on the telescopic end of the first hydraulic rod 301 drives the contact member to descend. At this time, the lifting plate 5 is driven to descend, and the touch switch 402 on the contact member contacts the sheet. Therefore, the electromagnetic iron plate 6013 is energized. After the electromagnetic iron plate 6013 is energized, magnetic attraction is generated, so as to adsorb the metal plate 611 at the bottom of the lower fixing plate 602 in the detection mechanism. The metal plate 611 is adsorbed by the electromagnetic iron plate 6013, and the lifting plate 5 is located above the sheet. The lower fixing plate 602 and the upper fixing plate 601 are rotatably connected by the first hinged rods 603 and a plurality of second hinged rods 605. As Figure 5 and Figure 6 shown in the figure, the second hinged rods 605 arranged in a cross shape move equidistantly, so that the humidity sensors 607 on the plurality of connecting shafts 606 move equidistantly, so as to adjust for sheets of different thicknesses, so that the plurality of humidity sensors 607 can detect the humidity at different positions of the sheet. The humidity sensor 607 can be a non-contact microwave humidity sensor. And as the contact member contacts different thickness positions of the sheet, the upper fixing plate 601 also rises and adjusts along with the lifting plate 5, which can be adaptively adjusted. When the detected humidity exceeds the specified value, the dehumidification mechanism is started to heat its position to adjust its humidity.

[0057] In this solution, the elastic member is set as a second telescopic rod 608 and a second spring 609. The two ends of the second telescopic rod 608 and the second spring 609 are respectively fixedly connected to the lower fixing plate 602 and the upper fixing plate 601. Thus, when the magnetic attraction between the metal plate 611 and the electromagnetic iron plate 6013 is released, the lower fixing plate 602 is driven to rise and reset to prepare for the next detection.

[0058] In this embodiment, as Figure 7As shown in the figure, the detection mechanism is set into two groups. A limiting groove 501 is formed on the surface of the lifting plate 5. The top of the upper fixing plate 601 passes through the limiting groove 501 and is slidably connected to the lifting plate 5. Both sides of the top of the lifting plate 5 are provided with first lead screws 704. The outer sides of the two first lead screws 704 are rotatably connected to support plates 705. The support plates 705 are fixedly connected to the lifting plate 5. The outer sides of the two first lead screws 704 are connected with sliding seats 701 through ball screw nuts. A third telescopic rod 702 and a third spring 703 are fixedly connected between the two sliding seats 701 and the two upper fixing plates 601 respectively. And the third spring 703 is sleeved on the outer side of the third telescopic rod 702. One end of each of the two first lead screws 704 is fixedly connected with a belt pulley 706. The two belt pulleys 706 are connected by a belt in a transmission manner. The top of the lifting plate 5 is fixedly connected with a micro motor 707. The output shaft of the micro motor 707 is fixedly connected with the first lead screw 704. Two humidifiers 708 are fixedly connected to the bottom of the lifting plate 5. After the two detection mechanisms are alternated, the multiple humidity sensors 607 are detected by the humidifiers 708.

[0059] During specific implementation, in order to ensure the accuracy of the detection by the humidity sensor 607 during each detection process in this solution, therefore, in this solution, by setting two groups of detection mechanisms, when it is necessary to calibrate the detection mechanism, by starting the humidity sensor 607, the output shaft of the humidity sensor 607 drives one of the first lead screws 704 to rotate. And the two first lead screws 704 are connected by belt pulleys 706 and a belt in a transmission manner. Furthermore, the two first lead screws 704 rotate synchronously, so that the sliding seats 701 on the two first lead screws 704 move alternately. The sliding seat 701 drives the upper fixing plate 601 to slide on the limiting groove 501 formed on the lifting plate 5 through the third telescopic rod 702 and the third spring 703. When one of the detection mechanisms moves to one end of the limiting groove 501, humidification treatment is carried out by the humidifier 708. The humidity of the sensor is increased by more than 20%RH within 5 seconds when the humidifier 708 quickly humidifies the sensor. A normal sensor should respond and stabilize within 10 seconds. If the delay is more than 30 seconds, it means that the sensitivity is insufficient. Thus, the accuracy of the detection mechanism during the detection process is ensured, and detection errors are avoided.

[0060] Embodiment 3: As Figures 8 to 11 shown, the dehumidification mechanism includes a connecting cylinder 9. A plurality of air outlet holes 901 are formed on the side of the connecting cylinder 9 close to the plate. And two isolation plates 904 are fixedly connected to the outside of the air outlet holes 901. The two isolation plates 904 are respectively arranged on both sides of the air outlet holes 901 and are used for contacting the plate during dehumidification. A hot air blower 900 is fixedly connected to the outside of the platform 1. The output end of the hot air blower 900 is connected to the connecting cylinder 9 through an air pipe.

[0061] The adjusting member includes a connecting rod 502, the connecting rod 502 is fixedly connected to the outside of the lifting plate 5, and an electromagnet ring 503 is fixedly connected to the outside of the connecting rod 502. The electromagnet ring 503 is provided with an opening. A sealing plate 902 is arranged inside the connecting cylinder 9. A fifth spring 903 is fixedly connected between the sealing plate 902 and the top end inside the connecting cylinder 9. When the electromagnet ring 503 descends with the lifting plate 5 and sleeves on the outside of the connecting cylinder 9, the electromagnet ring 503 drives the sealing plate 902 to descend through magnetism.

[0062] During specific implementation, when the lifting plate 5 descends together with the contact frame 4, the connecting rod 502 drives the fixedly connected electromagnet ring 503 to descend together, so that the electromagnet ring 503 sleeves on the outside of the connecting cylinder 9. At this time, the electromagnet ring 503 drives the sealing plate 902 inside the connecting cylinder 9 through magnetic attraction. When the bottom plate of the contact member contacts, the electromagnet ring 503 no longer moves. At this time, it drives the sealing plate 902 to move to the position of the plate thickness, and the sealing plate 902 seals the upper part of the connecting cylinder 9, so that the hot air inside the connecting cylinder 9 can be discharged through some air outlet holes 901, so as to control the humidity for plates of different thicknesses.

[0063] In this embodiment, as Figure 11 shown, sliding grooves 9041 are formed on the opposite sides of the two isolation plates 904, and a magnetic upper baffle 905 is arranged inside the isolation plates 904. The magnetic upper baffle 905 partially extends into the sliding groove 9041 and is slidably connected to the sliding groove 9041, and the magnetic upper baffle 905 is magnetically adsorbed to the sealing plate 902.

[0064] During specific implementation, in order to ensure that when adjusting the humidity of a local area, two isolation plates 904 are fixedly connected to the outside of the connecting cylinder 9. When the isolation plates 904 contact the plate, it avoids affecting other positions at the cut of the plate. At the same time, when the electromagnet ring 503 slides on the outside of the connecting cylinder 9, the magnetic upper baffle 905 between the two isolation plates 904 is also driven to slide together through magnetism, forming a dehumidification space. And ventilation holes are formed on the outside of the magnetic upper baffle 905, and the moisture is discharged through the ventilation holes of the magnetic upper baffle 905.

[0065] In this embodiment, a moving seat 801 is slidably connected inside the fixed frame 8. The connecting cylinder 9 is fixedly connected to the top of the moving seat 801, and a contact ring 802 is rotatably connected to the outside of the connecting cylinder 9 for contacting the plate. A fourth spring 803 is fixedly connected between the moving seat 801 and one end inside the fixed frame 8, and a baffle 804 is fixedly connected inside the fixed frame 8.

[0066] During specific implementation, before cutting, when the operator places the plate, the plate contacts the contact ring 802, squeezing the contact ring 802, so that the moving seat 801 moves inside the fixed frame 8. After the first cutting is completed, under the action of the fourth spring 803, the fourth spring 803 pushes the moving seat 801 to reset. At this time, the contact ring 802 moves to the same level as the cutting device 102. When the plate cutting is completed and the plate is retracted, the cutting surface will not contact the cutting device 102, and the baffle 804 can block the moving seat 801, each time resetting the moving seat 801 to the position of the cutting surface of the plate, making the isolation plate 904 fit the cutting surface of the plate. After the processing is completed, the plate is moved again to perform the final position cutting of the plate.

[0067] A wood mold processing method based on the construction of an arc-shaped roof includes the following steps:

[0068] Step 1: Place the softened plate on the top of the placement plate 2 by means of a steam softening process, fix the plate through the clamping assembly, and perform two cuts on the set cutting distance through the cutting device 102;

[0069] Step 2: After the first cutting is completed, start the first hydraulic rod 301 to make the contact member contact the top of the plate, and then drive the plate to retreat through the moving device 201. The contact member drives the detection mechanism to descend to one side of the plate cutting surface, and the humidity of the plate cutting surface is detected through the detection mechanism;

[0070] Step 3: When the detected humidity exceeds the preset value, locally heat the part of the cutting surface with excessive humidity through the dehumidification mechanism. When the humidity reaches the standard, perform the final cutting and forming.
