Description

Technical Field

[0001] The present invention relates to the technical field of furniture production, and in particular to an auxiliary pressing device for arc-shaped plates and a manufacturing method thereof. Background Art

[0002] In the existing furniture market, most common panel furniture is horizontal, vertical, and angular, which is not satisfactory in terms of safety and difficult to meet the needs of consumers in terms of aesthetics. Currently, the popular method for manufacturing three-dimensional arc furniture in the market is to use multiple 2-mm or 3-mm density boards to form a plate with a certain thickness through long-time heating and bending by a high-frequency press. However, the bent plates have a risk of rebound and fracture after hot pressing and shaping. Summary of the Invention

[0003] Aiming at the defects of the above prior art, one of the purposes of the present invention is to provide an auxiliary pressing device for arc-shaped plates, which can provide continuous pressure for arc-shaped plates.

[0004] One of the purposes of the present invention is achieved by the following technical solutions:

[0005] An auxiliary pressing device for arc-shaped plates includes a support base and a pressing mechanism. The support base is provided with a support fitting surface matching the radian of the arc-shaped plate. The arc-shaped plate has a bending wide groove with a radian angle of R, and the bending wide groove is filled with bending wooden blocks. Both the bending wide groove and the bending wooden blocks are coated with curing glue. The support fitting surface is provided with a limiting structure for restricting the arc-shaped plate from detaching from the support base. The pressing mechanism includes a U-shaped clamping plate, two clamping screws, and a pressing screw. The two sides of the opening of the U-shaped clamping plate are symmetrically provided with first screw holes threadedly engaged with the clamping screws, and the bottom of the U-shaped clamping plate is provided with a second screw hole threadedly engaged with the pressing screw. The clamping screws horizontally pass through the first screw holes and are threadedly connected with the first screw holes, and the pressing screw vertically passes through the second screw hole and is threadedly connected with the second screw hole. The clamping screws are used to clamp and fix the U-shaped clamping plate on the support base, and the pressing screw is used to apply axial pressure to the arc-shaped plate.

[0006] Further, the pressing screw and the clamping screws are both provided with operating handles.

[0007] Further, the support base includes a support vertical plate with an L-shaped structure. One side of the support vertical plate is successively formed with a vertical side surface, an arc surface, and a horizontal surface from top to bottom. The vertical side surface, the arc surface, and the horizontal surface are smoothly and transitionally connected to form the support fitting surface. The pressing mechanism is clamped on the vertical side surface, and one end of the horizontal surface far from the arc surface protrudes upward to form the limiting structure.

[0008] Further, the support base further includes a bottom plate and a front baffle. There are at least two support vertical plates, and at least two support vertical plates are arranged in parallel at intervals along the same straight line. The bottoms of adjacent two support vertical plates are connected by the bottom plate. The front baffle is arranged at the front end of the support base and is perpendicular to the bottom plate. The top of the front baffle is flush with the top of the limiting structure.

[0009] The second object of the present invention is to provide a manufacturing method of an arc plate member to solve the problem of rebound fracture existing in the arc plate member after hot pressing and shaping.

[0010] The second object of the present invention is achieved by the following technical solutions:

[0011] A manufacturing method of an arc plate member uses the above-mentioned auxiliary pressurizing device. The manufacturing method includes the following steps:

[0012] a. Determine the radian angle R of the required arc plate member;

[0013] b. Plate member processing: Use a carving machine to mill a bending wide groove with a radian angle of R at the position where the plate member needs to be bent to obtain an arc plate member;

[0014] c. Wood block processing: According to the radian angle R and the depth of the bending wide groove, use a carving machine to mill multiple milling grooves on the flat wood block to obtain a bending wood block. The width of the bending wood block is 1 mm smaller than the width of the bending wide groove;

[0015] d. Fixing the arc plate member: Fix the arc plate member on the auxiliary pressurizing device, where the bending position of the arc plate member fits on the arc surface, the vertical part of the arc plate member leans against the vertical side surface of the support vertical plate, and the horizontal part of the arc plate member is supported on the horizontal surface;

[0016] e. Gluing and filling the bending wood block: First, apply a curing glue evenly inside the bending wide groove, then put the bending wood block into the bending wide groove, and apply the curing glue on the surface of the bending wood block and inside the milling grooves;

[0017] f. Pressurizing: Rotate the pressurizing screw, the pressurizing screw vertically presses against the top of the vertical part of the plate member, and apply a pressure within a preset range to the arc plate member through the pressurizing screw;

[0018] g. Under normal temperature conditions, maintain the fixed pressure. After the glue hardens, the manufacturing of the arc plate member is completed.

[0019] Further, in step b, the thickness of the arc plate member at the bending wide groove is 0.8 - 1.4 mm.

[0020] Further, in step e, there is a fitting gap between the bending wood block and the bending wide groove. When the fitting gap ≤ 1 mm, it is considered that the two reach a tightly bonded state.

[0021] Further, in step f, when the axial pressure applied by the pressing screw is 220 - 320 N, the bent portion of the arc-shaped plate member and the bending wooden block reach a close bonding effect.

[0022] Further, the plate member is formed by laminating a melamine paper layer and a medium fiber layer into a melamine medium fiber plate member.

[0023] Compared with the prior art, the beneficial effects of the present invention at least include:

[0024] (1) The auxiliary pressing device for the arc-shaped plate member of the present invention is provided with a supporting fitting surface, and the supporting fitting surface has a curved surface adapted to the plate member to be pressed. In this way, the plate member to be pressed can better fit on the supporting seat. At the same time, the setting of the limiting structure facilitates the positioning of the plate member to be pressed and the supporting fitting surface, and the limiting structure can also ensure that the position of the plate member to be pressed does not shift during pressing; by applying an axial pressure to the plate member to be pressed through the pressing mechanism, continuous pressure can be provided for the plate member to be pressed. The pressing method is simple and convenient. At the same time, the pressing mechanism can move vertically, which can adapt to plate members of different specifications and sizes, and has high flexibility.

[0025] (2) The manufacturing method of the arc-shaped plate member of the present invention uses a carving machine to mill a bending wide groove with a radian angle of R at the position where the plate needs to be bent to obtain an arc-shaped plate member. Then, the arc-shaped plate member is fixed on the auxiliary pressing device, and the arc-shaped plate member fits on the supporting fitting surface. After that, a curing glue is coated in the bending wide groove, and the bending wooden block is filled in the bending wide groove. The surface of the bending wooden block and the milled groove are both coated with the curing glue. Then, an axial pressure is applied to the arc-shaped plate member through the pressing mechanism, and the pressure is maintained and fixed. It only needs to be left to dry at room temperature for 2 hours. After the curing glue hardens, an arc-shaped plate member is formed. This manufacturing method applies continuous pressure to the arc-shaped plate member through the pressing mechanism, eliminating the need for long-term hot pressing, effectively solving the risk of rebound and fracture that exists after the existing arc-shaped plate members are shaped by hot pressing. By filling the processed bending wooden block into the bending wide groove and then bonding the two together with the curing glue, and then pressing them together through the auxiliary pressing device, the overall production of the arc-shaped plate member is realized. The production cost is low, and the arc-shaped plate member is not prone to cracking. Moreover, the bending wooden block is used to strengthen the bent portion of the arc-shaped plate member to ensure the overall structural strength. Description of the Drawings

[0041] The words expressing positions and directions described in the present invention are all illustrated by taking the accompanying drawings as examples, but can be changed according to needs, and all the changes made are included in the protection scope of the present invention.

[0042] As Figures 1 - 5 shown, an auxiliary pressurizing device 10 for an arc-shaped plate member provided by the present invention includes a support base 11 and a pressurizing mechanism 12. The support base 11 is provided with a support fitting surface matching the radian of the arc-shaped plate member 20. The arc-shaped plate member 20 has a bending wide groove 21 with a radian angle of R. A bending wooden block 30 is filled in the bending wide groove 21. The bending wide groove 21 and the bending wooden block 30 are both coated with a curing glue. The support fitting surface is provided with a limiting structure 1113 for restricting the to-be-pressurized plate member from detaching from the support base 11. The pressurizing mechanism 12 includes a U-shaped clamping plate 121, two clamping screws 122 and a pressurizing screw 123. First screw holes threadedly engaged with the clamping screws 122 are symmetrically provided on both sides of the opening of the U-shaped clamping plate 121 respectively. A second screw hole threadedly engaged with the pressurizing screw 123 is provided at the bottom of the U-shaped clamping plate 121. The clamping screws 122 respectively pass through the first screw holes transversely and are threadedly connected to the first screw holes. The pressurizing screw 123 passes through the second screw hole vertically and is threadedly connected to the second screw hole. The clamping screws 122 are used to clamp and fix the U-shaped clamping plate 121 on the support base 11, and the pressurizing screw 123 is used to apply an axial pressure to the to-be-pressurized plate member. In this embodiment, the support fitting surface matches the radian of the arc-shaped plate member 20, so that the arc-shaped plate member 20 can better fit on the support base 11. At the same time, the setting of the limiting structure 1113 facilitates the positioning of the arc-shaped plate member 20 and the support fitting surface, and the limiting structure 1113 can also ensure that the position of the arc-shaped plate member 20 will not shift during pressurization; by applying an axial pressure to the arc-shaped plate member 20 through the pressurizing mechanism 12, continuous pressure can be provided for the arc-shaped plate member 20. The pressurizing method is simple and convenient. At the same time, the pressurizing mechanism 12 can move vertically and can adapt to plate members of different specifications and sizes, with high flexibility.

[0043] The U-shaped clamping plate 121 is fixed on the support base 11 by the clamping screw 122, which is simple and convenient to operate and is also convenient for adjusting the position of the moving and pressing mechanism 12; the axial pressure is applied to the plate to be pressed by the pressing screw 123, ensuring that the force-receiving surface of the plate to be pressed receives uniform, stable, symmetric and perpendicular pressure, improving the test effect while ensuring the test efficiency.

[0044] As a preferred embodiment, the pressing screw 123 and the clamping screw 122 are both provided with operating handles 124. Through the operating handles 124, it is convenient to rotate the pressing screw 123 and the clamping screw 122, and the operation is simple and convenient.

[0045] As a preferred embodiment, the support base 11 includes a support vertical plate 111 with an L-shaped structure. On one side of the support vertical plate 111, a vertical side surface 1110, a circular arc surface 1111 and a horizontal surface 1112 are formed in sequence from top to bottom. The vertical side surface 1110, the circular arc surface 1111 and the horizontal surface 1112 are smoothly and transitionally connected to form the support fitting surface. The pressing mechanism 12 is clamped on the vertical side surface 1110, and a limiting structure 1113 is formed by the upward protrusion of one end of the horizontal surface 1112 away from the circular arc surface 1111.

[0046] In this embodiment, the vertical side surface 1110, the circular arc surface 1111 and the horizontal surface 1112 of the support vertical plate 111 are smoothly and transitionally connected to form the support fitting surface, which has the characteristics of simple structure and convenient processing.

[0047] As a preferred embodiment, the support base 11 further includes a bottom plate 112 and a front baffle 113. There are at least two support vertical plates 111. At least two support vertical plates 111 are arranged in parallel at intervals along the same straight line. The bottoms of adjacent two support vertical plates 111 are connected by the bottom plate 112. The front baffle 113 is arranged at the front end of the support base 11 and is perpendicular to the bottom plate 112. The top of the front baffle 113 is flush with the top of the limiting structure 1113.

[0048] In this embodiment, by providing at least two support vertical plates 111 arranged in parallel at intervals, it is beneficial to increase the support area of the support fitting surface. The bottoms of the support vertical plates 111 are connected by the bottom plate 112 to ensure the stability of the support vertical plates 111; the setting of the front baffle 113 is beneficial to fixing the plate to be pressed.

[0049] The present invention also provides a manufacturing method for an arc plate. Using the above-mentioned auxiliary pressing device 10, the manufacturing method includes the following steps:

[0050] a. Determine the radian angle R of the required arc plate 40;

[0051] b. Plate processing: Use a carving machine to mill a bending wide groove 21 with a radian angle of R at the position where the plate needs to be bent to obtain an arc-shaped plate 20, as Figures 6 - 7 shown;

[0052] c. Wood block processing: According to the radian angle R and the depth of the bending wide groove 21, use a carving machine to mill multiple milling grooves 31 on the flat wood block to obtain a bending wood block 30, as Figures 8 - 9 shown. The width of the bending wood block 30 is 1 mm smaller than the width of the shown bending wide groove 21, so that the bending wood block 30 can be filled in the bending wide groove 21;

[0053] d. Fixing the arc-shaped plate 20: Fix the arc-shaped plate 20 on the auxiliary pressing device 10, where the bending position of the arc-shaped plate 20 is attached to the circular arc surface 1111, the vertical part 22 of the arc-shaped plate 20 leans against the vertical side surface 1110 of the supporting vertical plate 111, and the horizontal part 23 of the arc-shaped plate 20 is supported on the horizontal plane 1112, as Figure 10 shown;

[0054] e. Gluing and filling the bending wood block 30: First, apply curing glue evenly inside the bending wide groove 21, then put the bending wood block 30 into the bending wide groove 21, and apply curing glue on the surface of the bending wood block 30 and inside the milling grooves 31;

[0055] f. Pressurizing: Rotate the pressure screw 123, the pressure screw 123 vertically presses against the top of the vertical part 22 of the plate, and apply a preset range of pressure to the arc-shaped plate 20 through the pressure screw 123, as Figure 10 shown;

[0056] g. Under normal temperature conditions, maintain the fixed pressure. After the glue hardens, the arc-shaped plate 40 is made, as Figure 11 shown.

[0057] In this embodiment, it is preferably to use a carving machine to mill a bending wide groove 21 with a radian angle of R at the position where the plate needs to be bent to obtain an arc-shaped plate 20, then fix the arc-shaped plate 20 on the auxiliary pressing device 10, the arc-shaped plate 20 is attached to the supporting joint surface, then apply curing glue in the bending wide groove 21, fill the bending wood block 30 in the bending wide groove 21, apply curing glue on the surface of the bending wood block 30 and at the milling grooves 31, then apply axial pressure to the arc-shaped plate 20 through the pressing mechanism 12, maintain the fixed pressure, and only need to air dry at normal temperature for 2 hours. After the curing glue hardens, the arc-shaped plate 40 is formed. This manufacturing method applies continuous pressure to the arc-shaped plate 20 through the pressing mechanism 12, without long-term hot pressing, effectively solving the risk of rebound and fracture that exists after the existing arc-shaped plate 40 is shaped by hot pressing.

[0058] In addition, in the present invention, the processed bent wooden block 30 is filled in the bent wide groove 21, and then the two are bonded together by a curing adhesive, and then pressed together by the auxiliary pressing device 10 to realize the overall production of the arc plate member 40. The production cost is low, and the produced arc plate member 40 is not prone to cracking, and the bent wooden block 30 is used to strengthen the bent portion of the arc plate member 40 to ensure the overall structural strength.

[0059] As a preferred embodiment, the thickness of the bent wide groove 21 of the arc plate member 20 is 0.8-1.4 mm.

[0060] As a preferred embodiment, in step e, there is a fitting gap at the joint between the bent wooden block 30 and the bent wide groove 21. When the fitting gap ≤ 1 mm, it is considered that the two reach a tightly bonded state.

[0061] Please refer to Figure 12 Table 1. Since the bent wooden block 30 and the bent wide groove 21 are fitted together by a curing adhesive, there will be a fitting gap between the two. The fitting gap is related to the amount of glue applied. Experiments show that when the amount of glue applied inside the bent wide groove 21 is less than 70 g and the amount of glue applied on the bent wooden block 30 is less than 500 g, the fitting degree between the bent wide groove 21 and the bent wooden block 30 is insufficient, resulting in a poor fitting effect; when the amount of glue applied inside the bent wide groove 21 is greater than 70 g and the amount of glue applied on the bent wooden block 30 is greater than 500 g, there is an overflow of glue at the joint between the bent wide groove 21 and the bent wooden block 30, which will affect the subsequent curing effect; when the amount of glue applied inside the bent wide groove 21 is 70 g and the amount of glue applied on the bent wooden block 30 is 500 g, the bent wide groove 21 and the bent wooden block 30 are fitted properly; it can be seen that when the ratio of the amount of glue applied inside the bent wide groove 21 to the amount of glue applied on the bent wooden block 30 is 70-500, the fitting gap ≤ 1 mm, and at this time the two reach a tightly bonded state.

[0062] As a preferred embodiment, in step f, the axial pressure applied by the pressing screw 123 is 220-320 N, and the bent portion of the arc plate member 20 and the bent wooden block 30 reach a tightly bonded effect.

[0063] In this embodiment, since pressure is applied to the arc plate member 20 through the pressing screw 123, the pressure determines the fitting effect between the bent portion of the arc plate member 20 and the bent wooden block 30. Please refer to Figure 13Table 2 shows the gap distance between the bent part of the arc-shaped plate member 20 and the bent wooden block 30 when the pressing screw 123 applies different axial pressures: when the axial pressure applied by the pressing mechanism 12 is less than 220 N, due to insufficient pressure, the bent part of the arc-shaped plate member 20 and the bent wooden block 30 cannot be closely adhered, that is, there will be too large a gap when the bent part of the arc-shaped plate member 20 is in contact with the bent wooden block 30. Tests show that when the gap distance > 1 mm, the close adhesion effect is not achieved; when the axial pressure applied by the pressing mechanism 12 is greater than 320 N, due to excessive pressure, the bent part of the arc-shaped plate member 20 and the bent wooden block 30 are damaged; when the axial pressure applied by the pressing mechanism 12 is 220 - 320 N, the bent part of the arc-shaped plate member 20 and the bent wooden block 30 show a close adhesion effect, and the gap distance ≤ 1 mm. It can be seen that the axial pressure applied by the pressing screw 123 cannot be too large or too small. Tests show that when the axial pressure applied by the pressing screw 123 is 220 - 320 N, the bent part of the arc-shaped plate member 20 and the bent wooden block 30 achieve a close adhesion effect, that is, the gap distance S ≤ 1 mm.

[0064] As a preferred embodiment, the plate member is formed by laminating a melamine paper layer and a medium fiber layer into a melamine medium fiber plate member. In this embodiment, the arc-shaped plate member 40 is made of the melamine medium fiber plate member, which has the advantages of environmental protection, wear resistance, high temperature resistance, corrosion resistance, waterproof, simplicity and convenience.

[0065] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and purposes of the present invention. All such changes should fall within the protection scope of the claims of the present invention.
