Description

Technical Field

[0001] The invention belongs to the technical field of wood processing equipment, and in particular relates to an arc-shaped cutting device for wooden furniture panels. Background Art

[0002] Wooden furniture refers to various types of furniture made of natural wood and wood-based panels as the main materials, with other auxiliary materials (such as paint, veneer materials, glass, hardware accessories, etc.). During the production process of wooden furniture, the boards need to be cut according to the structure of the furniture, and many of the boards need to be cut with rounded corners or curved edges.

[0003] Traditionally, arc cutting of wooden furniture panels is done by manually controlling the panels with a circular saw or a wire saw. The manual control accuracy is not high, and cutting deviations are prone to occur. The circular saw cuts a larger surface, has a lower arc cutting accuracy, and an uneven arc surface. Although the wire saw cuts a smaller surface, it uses reciprocating motion for cutting, so the surface has more rough edges. When encountering some artificial boards, the tension of the up and down reciprocating motion may cause the panel surface to warp, resulting in damage to the panel. Therefore, the existing arc cutting equipment is not very ideal for cutting the arc surface of the panel. Moreover, the current equipment can only perform arc cutting when cutting, and cannot form an inclination of the cutting surface, nor can it achieve cutting of a sloped arc surface, so the application scenarios are limited. Summary of the Invention

[0046] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following examples. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0047] like Figure 1-11 As shown, a device for arc cutting of wooden furniture panels comprises a box body 1 for providing support, a support frame body 2 for connecting and installing various components, a cutting platform 3 for placing panels, and a cutting component 4 for arc cutting.

[0048] Refer to the attached Figure 1-2, wherein the first angle scale hole 12 and the second angle scale hole 15 are symmetrically opened on the front and back of the box body 1 for reference to adjust the cutting angle of the cutting assembly 4, and a console 11 for controlling the device is set on the front of the box body 1.

[0049] Refer to the attached Figure 10-11 , wherein the support frame 2 is fixedly installed inside the top of the box body 1, and a rotating support 21 is symmetrically installed on the side of the support frame 2. A support platform 23 is integrally formed on the inner side of the support frame 2. A track 27 is fixedly installed on the top surface of the support platform 23, and a slide 28 is fixedly installed on the bottom surface of the movable platform 24. By sliding the slide 28 onto the track 27, the movable platform 24 can slide horizontally in the support frame 2. A support plate 25 is fixedly installed on the side of the support frame 2 away from the movable platform 24;

[0050] Furthermore, to facilitate the adjustment of the movable platform 24, a distance adjustment knob 14 is rotatably installed between the box body 1 and the support frame 2. At the same time, a threaded connection seat 29 is fixedly installed on the bottom surface of the movable platform 24. A screw 210 is threadedly connected to the threaded connection seat 29. A first universal ball shaft 211 is fixedly connected between the distance adjustment knob 14 and the screw 210. Through the setting of the first universal ball shaft 211, the rotation angle of the distance adjustment knob 14 can be transmitted to the screw 210 without hindrance, avoiding the situation of rotation jamming, making the adjustment smoother. Therefore, by utilizing the threaded connection between the screw 210 and the threaded connection seat 29, the movable platform 24 can move along the track 27 according to the rotation of the distance adjustment knob 14, thereby realizing distance adjustment.

[0051] Furthermore, a buffer support 212 is fixedly installed at the center of the bottom surface of the movable platform 24, and a buffer spring 213 is fixedly connected between the buffer support 212 and the inner wall of the support frame 2. In this way, the buffer spring 213 can be stretched or compressed at the same time when the movable platform 24 moves, thereby reducing the moving speed of the movable platform 24, buffering the moving potential energy, and ensuring the accuracy of the adjustment.

[0052] Refer to the attached Figure 8-10 The cutting platform 3 is symmetrically divided into two pieces, which are slidably connected to the movable platform 24 and the support plate 25 respectively. A central through hole 31 is opened in the center of the cutting platform 3, and scale lines 32 are etched on both sides. When cutting the plate, the distance can be adjusted with reference to the scale lines 32 to ensure cutting accuracy.

[0053] In this embodiment, a longitudinal slide bar 38 is fixedly mounted on the bottom surface of the cutting platform 3, and a first slide pin 26 is fixedly mounted on the top surface of the movable platform 24 and the support plate 25. By sliding the longitudinal slide bar 38 onto the first slide pin 26, the cutting platform 3 can be moved longitudinally relative to the support frame 2 as needed.

[0054] Furthermore, in order to facilitate the control and adjustment of the left and right platforms of the cutting platform 3, side rails 34 are fixedly embedded on both sides of the top surface of the cutting platform 3, and a fixed base 35 is provided between the left and right platforms of the cutting platform 3. At the same time, second sliding pins 37 are fixedly installed on both ends of the bottom surface of the fixed base 35, and the side is threadedly connected with a first threaded knob 36. By sliding the second sliding pin 37 to engage with the inside of the side rail 34, the left and right platforms can be aligned by fixing the base 35 when they are moved left and right, and the adjustment positioning of the two platforms can be achieved by rotating the first threaded knob 36 against the side of the cutting platform 3.

[0055] Refer to the attached Figure 3-4 , wherein the cutting assembly 4 includes a supporting keel 41 installed between the rotating supports 21, the supporting keel 41 is rotatably installed between the rotating supports 21, a right-angle transmission seat 42 is fixedly installed at the center of one side of the supporting keel 41, a drill-shaped cutter 43 is rotatably installed on the right-angle transmission seat 42, and the drill-shaped cutter 43 extends from the center of the central through hole 31, and a servo motor 44 for driving the drill-shaped cutter 43 is fixedly installed on the other side of the supporting keel 41, and the servo motor 44 is connected to the right-angle transmission seat 42 through a pulley assembly to drive the drill-shaped cutter 43;

[0056] In order to facilitate the adjustment of the cutting angle of the drill-shaped cutter 43, sliding sleeves 45 are fixedly installed on both sides of the support keel 41. Vertical tracks 46 are slidably engaged on the sliding sleeves 45. A rotating connecting seat 47 is fixedly installed on the top of the vertical track 46. The rotating connecting seat 47 is rotatably connected to the inner wall of the rotating support 21. At the same time, a limiting arc groove 22 is provided on the inner side of the rotating support 21, and a limiting protrusion 48 is integrally formed on the outer side of the rotating connecting seat 47. By sliding the limiting protrusion 48 into the limiting arc groove 22, the circumferential arc rotation of the support keel 41 can be stably limited, thereby facilitating the adjustment of the cutting angle of the drill-shaped cutter 43.

[0057] Furthermore, to facilitate adjustment of the height of the drill-shaped cutter 43, an adjustment support 415 is fixedly installed at the bottom end of the vertical track 46 just below the support keel 41. A spring buffer 416 is fixedly installed between the support keel 41 and both ends of the adjustment support 415. An adjustment screw 417 is threadedly connected between one end of the support keel 41 and the adjustment support 415. In this way, by rotating the adjustment screw 417 and buffering with the spring buffer 416, the support keel 41 can be moved up and down relative to the adjustment support 415 under the cooperation of the sliding sleeve 45 and the vertical track 46, thereby adjusting the height of the drill-shaped cutter 43.

[0058] Furthermore, in order to accurately adjust the cutting angle of the drill-shaped cutter 43, a central connecting rod 411 is fixedly installed between the bottom ends of the vertical rails 46, and an angle adjustment knob 13 is rotatably installed on the box body 1. The center of the central connecting rod 411 is rotatably connected to a cross seat 412, and the other end of the cross seat 412 is threadedly connected to a screw rod 413. A second universal ball shaft 414 is fixedly connected between the screw rod 413 and the angle adjustment knob 13. The second universal ball shaft 414 can be used to smoothly transmit the rotation of the angle adjustment knob 13 to the screw rod 413 to avoid jamming. In this way, the screw rod 413 is driven to rotate by the angle adjustment knob 13 through the second universal ball shaft 414, so that the support is pulled by the contraction of the screw rod 413 relative to the cross seat 412. The keel 41 is rotated relative to the rotating support 21 through the rotating connecting seat 47, thereby realizing the adjustment of the inclination angle of the drill-shaped cutter 43, so that the cut surface of the drill-shaped cutter 43 has a slope at a certain angle; at the same time, a side connecting seat 49 is fixedly installed on the outer side of the bottom end of the vertical track 46, and a second threaded knob 410 is threadedly connected on the side connecting seat 49 to match the first angle scale hole 12 and the second angle scale hole 15. It can be adjusted to a specified angle relative to the first angle scale hole 12 and the distance adjustment knob 14, and the inclination angle can be positioned by inserting the second threaded knob 410 into the first angle scale hole 12 and the distance adjustment knob 14 and threading it into the inside of the side connecting seat 49 to ensure stability during cutting.

[0059] Refer to the attached Figure 2 and Figure 4 The arc-shaped cutting seat 5 includes a longitudinal support 51 slidably mounted on one of the cutting platforms 3. The center of the longitudinal support 51 is rotatably connected to a transverse rotating clamping seat 52. A clamping plate 56 is slidably embedded in the top of the bayonet of the transverse rotating clamping seat 52. A positioning screw 57 is rotatably connected to the clamping plate 56. The positioning screw 57 is threadedly connected to the top wall of the transverse rotating clamping seat 52. The bottom ends of the longitudinal support 51 are fixedly mounted with third sliding pins 54 that match the side rails 34. The third sliding pins 54 are slidably engaged with the inside of the side rails 34. The center of the longitudinal support 51 is threadedly connected to a third threaded knob 53.

[0060] According to the above structure, the plate can be clamped inside the transverse rotating clamp 52, and by rotating the positioning screw 57, the plate is clamped by moving the clamping plate 56 downward. Then, the servo motor 44 is started through the control console 11, driving the drill cutter 43 to rotate at high speed, while slowly pushing the longitudinal support 51, so that the plate gradually approaches the drill cutter 43 for cutting. After the cutting depth reaches the arc line position, the third threaded knob 53 is rotated to position the longitudinal support 51, and then the transverse rotating clamp 52 is slowly rotated, and the drill cutter 43 cuts the rotating plate, thereby achieving arc cutting of the plate.

[0061] In addition, the longitudinal slide bar 38 can also be used to slide and engage with the first slide pin 26 to move the arc cutting seat 5 and the cutting platform 3 longitudinally relative to the drill cutter 43, thereby achieving cutting without arc edges, making the arc cutting of the plate more diversified and meeting the needs of different forms of arc cutting;

[0062] Furthermore, in order to facilitate the rotation of the transverse rotating clamp 52, a ball 55 is rolled and embedded between the end of the transverse rotating clamp 52 and the top surface of the cutting platform 3. In this embodiment, there are two balls 55 rolled and embedded in parallel, which can reduce the sliding friction when the transverse rotating clamp 52 rotates, making the rotation smoother and reducing the wear on the cutting platform 3.

[0063] Refer to the attached Figure 5 and Figure 7 , wherein, in order to achieve bevel cutting and improve the functionality of the device, this embodiment also includes an angled cutting seat 6, which includes a positioning block 61 attached to the surface of the cutting platform 3, a positioning plate 62 fixedly installed on the side of the positioning block 61, a swing handle 64 fixedly welded to the end of the positioning block 61, and a fourth threaded knob 63 is threadedly connected to both ends of the positioning plate 62 and the swing handle 64. At the same time, one of the cutting platforms 3 is provided with an angle through hole 33 for cooperation therewith, and also a positioning through hole that cooperates with the fourth threaded knob 63 is provided;

[0064] According to the above structure, when performing bevel cutting of the plate, the fourth threaded knob 63 of the positioning plate 62 away from the swing handle 64 can be rotated and fixed in the positioning through hole, and the swing handle 64 can be used to rotate and swing the positioning block 61, and the required cutting angle can be determined by referring to the angle through hole 33. After rotating to the specified angle, the bevel angle can be determined by fixing and inserting the fourth threaded knob 63 at the other end of the positioning plate 62 into the angle through hole 33. Thereafter, the plate is pushed along the positioning block 61, and the drill-shaped cutter 43 is used to cut the plate, thereby achieving bevel cutting.

[0065] Refer to the attached Figure 3 , wherein, in order to clean the wood chips generated during cutting, this embodiment further includes a dust collection assembly 7, which includes a dust collector 71 installed inside the box body 1, a detachable dust collection cylinder 72 is provided at the bottom of the dust collector 71, a corrugated hose 73 is connected to the dust suction port of the dust collector 71, and a dust suction pipe opening 74 is integrally formed at the other end of the corrugated hose 73, and the dust suction pipe opening 74 is embedded in the center through hole 31 and surrounds the outer surface of the right-angle transmission seat 42;

[0066] According to the above structure, the vacuum cleaner 71 can be started to generate negative pressure while cutting, and the wood chips are collected through the vacuum pipe mouth 74, so that they are collected into the dust collecting barrel 72 through the corrugated hose 73, so as to prevent the wood chips from flying during the cutting process and affecting the cutting line of sight, and also avoid contaminating the surface of the cutting platform 3.

[0067] The working principle of the present invention is as follows: first, the angle adjustment knob 13 can be rotated according to the slope of the apartment surface, and the angle adjustment knob 13 drives the screw rod 413 to rotate through the second universal ball shaft 414, so that the screw rod 413 is contracted relative to the cross seat 412 to pull the supporting keel 41 to rotate relative to the rotating support 21 through the rotating connecting seat 47, thereby adjusting the inclination angle of the drill-shaped cutter 43, so that the cutting surface of the drill-shaped cutter 43 has a certain angle of slope, and at the same time, it can be adjusted to a specified angle relative to the first angle scale hole 12 and the distance adjustment knob 14, and the second threaded knob 410 is inserted into the first angle scale hole 12 and the distance adjustment knob 14 and threadedly connected to the inside of the side connecting seat 49 to achieve positioning of the inclination angle, thereby ensuring stability during cutting;

[0068] Secondly, the distance adjustment knob 14 can be rotated according to the length of the plate. The distance adjustment knob 14 drives the screw 210 to rotate through the first universal ball shaft 211. The screw 210 is retracted relative to the threaded connection seat 29 to pull the movable platform 24 to slide on the support frame 2, thereby achieving the distance adjustment of the cutting platform 3 relative to the side rail 34.

[0069] Finally, the plate is clamped inside the transverse rotating clamp 52, and the plate is clamped by rotating the positioning screw 57 and moving the clamping plate 56 downward. Then, the servo motor 44 is started through the console 11 to drive the drill cutter 43 to rotate at high speed, and at the same time, the longitudinal support 51 is slowly pushed so that the plate gradually approaches the drill cutter 43 for cutting. After the cutting depth reaches the arc line position, the third threaded knob 53 is rotated to position the longitudinal support 51, and then the transverse rotating clamp 52 is slowly rotated to cut the rotating plate with the drill cutter 43 to achieve arc cutting of the plate; while cutting, the vacuum cleaner 71 is started to generate negative pressure, and the wood chips are adsorbed through the vacuum pipe mouth 74, so that they are collected into the dust collecting cylinder 72 through the corrugated hose 73, so as to avoid wood chips flying during the cutting process and affecting the cutting, and also to avoid contaminating the surface of the cutting platform 3.

[0070] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention.
