Description

Technical Field

[0001] This invention relates to the field of guitar side panel processing technology, and in particular to an automatic hot bending forming equipment for guitar side panels. Background Technology

[0002] The guitar, also known as the six-stringed guitar, is a plucked string instrument that typically has six strings and is similar in shape to a violin. Guitars are often considered a primary instrument in pop music, rock music, blues, folk music, and flamenco.

[0003] The guitar side panel is one of the main components of a guitar. In the process of processing the guitar side panel, it is usually produced by cutting the wood into shape or by hot bending.

[0004] When hot bending guitar side panels, due to the high toughness of the wood, it is necessary to soak it in hot water to soften the wood fibers, making it easier to bend and shape, and also to prevent it from breaking due to the dryness of the wood during the bending process. Existing guitar side panel hot bending equipment often relies on manual removal and reloading of the wood after soaking in water, which leads to low work efficiency and high work intensity. Therefore, we propose an automatic hot bending forming equipment for guitar side panels. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic hot bending forming equipment for guitar side panels, which can automatically feed heated wood to improve processing efficiency.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an automatic hot bending forming equipment for guitar side panels, characterized in that it includes a base plate and a forming mold and a heating tank mounted on the base plate.

[0007] The feeding assembly is installed on the heating tank body.

[0008] A drive assembly is installed on the heating tank and drives the feeding assembly to rotate periodically.

[0009] Anti-reverse components are symmetrically installed on the heating tank body to prevent the feeding component from retracting.

[0010] The pushing component is installed on the heating pool body and periodically coupled with the driving component. When coupled with the driving component, the pushing component moves away from the forming mold and moves upward to form a gap between itself and the feeding component for the side plate to pass through. When it is disengaged from the driving component, the pushing component moves closer to the forming mold and moves downward to fit against the surface of the feeding component.

[0011] By adopting the above technical solution, the sheet material to be processed is immersed in the heating tank. While the drive component drives the feeding component to rotate periodically, it also engages with the pushing component, moving it away from the forming mold and upward to form a gap between it and the feeding component for the side plate to pass through. At this time, the feeding component transports the next soaked sheet material through the gap to be flush with the edge of the heating tank. Then, the drive component no longer engages with the feeding component and the pushing component, the sheet material stops being transported, the pushing component moves down to fit the surface of the feeding component and pops out, sending the sheet material to the forming mold for hot bending. This process is repeated to achieve automatic conveying of the sheet material without manual feeding, thus improving work efficiency.

[0012] By adopting the above technical solution, when the drive component and the feeding component are no longer engaged, the anti-backward component can stabilize the feeding component, ensuring that the board material on the feeding component has no displacement or offset, and guaranteeing the repeatability and positioning accuracy of subsequent pushing actions.

[0013] By adopting the above technical solution, a series of actions such as feeding, pushing and automatic resetting of the board material can be realized by using a single drive source of the drive component, which can meet the needs of continuous operation, reduce the complexity of the equipment and save energy.

[0014] A further configuration of the present invention is as follows: the molding die includes a stand mounted on a base plate, an upper die slidably mounted on the stand, a cylinder I mounted on the stand to drive the upper die to move up and down, an upper metal heating plate mounted on the upper die, a bottom die mounted on the stand, side dies symmetrically hinged to the bottom die, a clamp mounted on the side die, a lower metal heating plate connected between the two clamps, and a cylinder II mounted on the stand. The output end of the cylinder II is hinged to the side die. A control box for controlling the cylinder I, cylinder II, the upper metal heating plate, and the lower metal heating plate is mounted on the stand.

[0015] By adopting the above technical solution, the heated side plate to be processed is sent to the lower metal heating plate through the pusher assembly. The first cylinder is started to make the upper mold move down and fit with the bottom mold to fix the center of the side plate. Then the second cylinder is started to make the two side plates flip up relative to the bottom mold and fit with the side of the upper mold, and the side plate is hot-pressed between the upper metal heating plate and the lower metal heating plate.

[0016] A further configuration of the present invention is as follows: the feeding assembly includes driven roller one, driven roller two, and driven roller three rotatably connected to the heating tank body; a drive shaft is rotatably connected to the inner wall of the heating tank body; a drive roller and a full gear are mounted on the outside of the drive shaft; and an inclined conveyor belt is also included to drive the drive roller and driven roller one, driven roller two, and driven roller three; the full gear is symmetrically arranged on both sides of the drive roller; driven roller one and driven roller two are at the same height; and driven roller three is higher than driven roller two and at the same height as the drive roller.

[0017] By adopting the above technical solution, the drive component periodically drives the drive shaft to rotate, causing the drive roller on the drive shaft to rotate. When the drive roller rotates, it drives the driven roller one, driven roller two, and driven roller three to rotate through the inclined conveyor belt, causing the inclined conveyor belt to rotate as a whole and convey the side plate. The drive roller and driven roller three are horizontally aligned to ensure that the side plate is in a horizontal position after conveying, which is convenient for the pusher component to push it to move. The driven roller one and driven roller two are horizontally aligned to facilitate the side plate to be submerged in water for heating. The driven roller three has a height difference with driven roller two, which facilitates the conveying and lifting of the side plate submerged in water.

[0018] A further feature of the present invention is that two sets of positioning components are installed on the inner wall of the heating pool. The two sets of positioning components are respectively attached to the upper and lower sides of the inclined conveyor belt. The two sets of positioning components are respectively located on the upper and lower sides of the driven roller 2. There are two positioning components in one set. The distance between the two positioning components in the same set is less than the length of the side plate to be processed.

[0019] By adopting the above technical solution, the positioning component is used to press down on the bend of the inclined conveyor belt, which shapes the bend without affecting the passage of the side plate.

[0020] A further configuration of the present invention is as follows: the drive assembly includes a mounting bracket mounted on the heating pool body, a drive motor mounted on the mounting bracket, a rotating shaft passing through the heating pool body and rotatably connected to its inner wall, and incomplete gear one and incomplete gear two mounted on the rotating shaft. Both incomplete gear one and incomplete gear two are provided with locking teeth. The distribution perimeter of the locking teeth does not exceed half the perimeter of incomplete gear one and incomplete gear two. The perimeter of the locking teeth on incomplete gear two is greater than the perimeter of the locking teeth on incomplete gear one. The locking teeth on incomplete gear one intermittently mesh with the full gear. The output shaft of the drive motor is connected to the rotating shaft through a coupling.

[0021] By adopting the above technical solution, the drive motor starts and drives the incomplete gear one and incomplete gear two on the rotating shaft to rotate. The incomplete gear one intermittently meshes with the full gear on the drive shaft, so that the inclined conveyor belt stops after moving a fixed distance each time. When it stops moving, the incomplete gear two no longer meshes with the pushing component. The pushing component can push the side plate on the inclined conveyor belt to the lower metal heating plate.

[0022] A further configuration of the present invention is as follows: the anti-reverse assembly includes a connecting spring mounted on the inner wall of the heating pool, a pawl mounted on the other side of the connecting spring, and a ratchet mounted on the gear, with the other side of the pawl engaging with the ratchet.

[0023] By adopting the above technical solution, when the incomplete gear one does not mesh with the full gear on the drive shaft, in order to prevent the side plate on the inclined conveyor belt from shifting, the ratchet and pawl can prevent the drive shaft from rotating in the opposite direction, ensuring that the plate on the inclined conveyor belt has no displacement or shift, and ensuring the repeatability and positioning accuracy of the subsequent pushing action.

[0024] A further embodiment of the present invention is that the feeding assembly includes a horizontal track symmetrically installed on the heating tank body, a rack plate slidably installed on the horizontal track, a connecting frame installed on the heating tank body, a support spring connecting the rack plate and the connecting frame, a sleeve installed on the rack plate, a movable plate sliding up and down inside the sleeve, and a scraper connecting the two movable plates.

[0025] A further feature of the present invention is that the rack plate periodically meshes with the teeth of the incomplete gear two, the inner wall of the sleeve near the connecting frame has a strip-shaped hole, and the bottom of the moving plate and the side of the connecting frame are set as mutually cooperating inclined surfaces.

[0026] A further feature of the present invention is that after the locking teeth on the incomplete gear two mesh with the rack plate, the locking teeth on the incomplete gear one mesh with the full gear on the drive shaft. When the locking teeth on the incomplete gear two do not mesh with the rack plate, the locking teeth on the incomplete gear one also no longer mesh with the full gear on the drive shaft.

[0027] By adopting the above technical solution, when the drive motor starts and drives the incomplete gear one and incomplete gear two on the rotating shaft to rotate, the incomplete gear two first meshes with the rack plate, so that the sleeve on the rack plate approaches the connecting frame. When it moves to the side of the connecting frame and the moving plate contacts the side of the connecting frame, and the scraper on the moving plate is lifted a certain distance by the inclined plane, the incomplete gear one meshes with the full gear to convey the side plate. When the cleats on the incomplete gear one and incomplete gear two do not mesh with the rack plate and the full gear, it means that the previous side plate has been conveyed and the next side plate stops being conveyed. At this time, the support spring resets and moves away from the connecting frame. The two inclined planes no longer abut against each other. Under the action of gravity, the scraper moves down and contacts the surface of the inclined conveyor belt and moves away from the connecting frame, sending the side plate on the inclined conveyor belt to the lower metal heating plate for hot bending. This process is repeated to realize the automatic conveying of the plate, eliminating the need for manual feeding and improving work efficiency.

[0028] A further feature of the present invention is that: notches are symmetrically provided on both sides of the heating pool body, and heat insulation material is installed on the inner wall of the heating pool body.

[0029] By adopting the above technical solution, the notch on one side facilitates the placement of the heated plate into the heating tank, while the notch on the other side facilitates the maintenance of the pushing component and the driving component. The insulation material can reduce the heat loss in the heating tank and better heat the plate.

[0030] The beneficial effects of this invention are:

[0031] 1. The sheet material to be processed is immersed in the heating tank. While the drive component drives the feeding component to rotate periodically, it also engages with the pushing component, moving it away from the forming mold and upward to form a gap between it and the feeding component for the side plate to pass through. At this time, the feeding component conveys the next soaked sheet material through the gap to be flush with the edge of the heating tank. Then, the drive component no longer engages with the feeding component and the pushing component, the sheet material stops being conveyed, the pushing component moves down to fit the surface of the feeding component and pops out, sending the sheet material to the forming mold for hot bending. This process is repeated to achieve automatic conveying of the sheet material without manual feeding, thus improving work efficiency.

[0032] 2. When the drive component and the feeding component are no longer engaged, the anti-backward component can be used to stabilize the feeding component, ensuring that the board material on the feeding component does not shift or deviate, and ensuring the repeatability and positioning accuracy of subsequent pushing actions.

[0033] 3. By using a single drive source, the material feeding, pushing and automatic resetting of the board are realized, which meets the needs of continuous operation, reduces the complexity of the equipment and saves energy. Attached Figure Description

[0042] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0043] Please see Figure 1-6 In some embodiments of the present invention, an automatic hot bending forming device for guitar side panels is provided, including a base plate 1, a forming mold 2 and a heating tank 3 mounted on the base plate 1.

[0044] The feeding assembly 4 is installed on the heating tank body 3.

[0045] The drive component 5 is installed on the heating tank body 3 and drives the feeding component 4 to rotate periodically.

[0046] Anti-retraction component 6 is symmetrically installed on the heating tank body 3 to prevent the feeding component 4 from retracting.

[0047] The pushing component 7 is installed on the heating pool body 3 and periodically coupled with the driving component 5. When coupled with the driving component 5, the pushing component 7 moves away from the forming mold 2 and moves upward to form a gap between itself and the feeding component 4 for the side plate to pass through. When it is disengaged from the driving component 5, the pushing component 7 moves closer to the forming mold 2 and moves downward to fit against the surface of the feeding component 4.

[0048] In the embodiments of this application, the sheet material to be processed is soaked in the heating tank 3. While the driving component 5 drives the feeding component 4 to rotate periodically, it also engages with the pushing component 7, moving it away from the forming mold 2 and upward to form a gap between it and the feeding component 4 for the side plate to pass through. At this time, the feeding component 4 transports the next soaked sheet material through the gap to be flush with the edge of the heating tank 3. Then, the driving component 5 no longer engages with the feeding component 4 and the pushing component 7, the sheet material stops being transported, the pushing component 7 moves down to fit the surface of the feeding component 4 and pops out, sending the sheet material to the forming mold 2 for hot bending. This process is repeated to achieve automatic conveying of the sheet material without manual feeding, thus improving work efficiency.

[0049] When the drive component 5 and the feeding component 4 are no longer engaged, the anti-backward component 6 can stabilize the feeding component 4, ensuring that the board material on the feeding component 4 has no displacement or offset, and ensuring the repeatability and positioning accuracy of subsequent pushing actions.

[0050] The single drive source of drive component 5 realizes a series of actions such as feeding, pushing and automatic resetting of the board, which meets the needs of continuous operation, reduces the complexity of the equipment and saves energy.

[0051] In some embodiments, the molding die 2 includes a stand 21 mounted on a base plate 1, an upper die 22 slidably mounted on the stand 21, a cylinder 23 mounted on the stand 21 to drive the upper die 22 to move up and down, an upper metal heating plate 24 mounted on the upper die 22, a bottom die 25 mounted on the stand 21, side dies 26 symmetrically hinged to the bottom die 25, clamps 27 mounted on the side dies 26, a lower metal heating plate 28 connected between the two clamps 27, and a cylinder 29 mounted on the stand 21. The output end is hinged to the side mold 26. The control box of the control cylinder 23, cylinder 29, upper metal heating plate 24 and lower metal heating plate 28 is installed on the upright frame 21. The heated side plate to be processed is sent to the lower metal heating plate 28 through the pusher assembly 7. The cylinder 23 is started to make the upper mold 22 move down and fit with the bottom mold 25 to fix the center of the side plate. Then the cylinder 29 is started to make the two side plates 26 flip upward relative to the bottom mold 25 and fit with the side of the upper mold 22. The side plate is hot-pressed between the upper metal heating plate 24 and the lower metal heating plate 28.

[0052] The feeding assembly 4 includes driven roller 1 41, driven roller 2 46, and driven roller 3 47 rotatably connected to the heating tank body 3. A drive shaft 42 is rotatably connected to the inner wall of the heating tank body 3. A drive roller 43 and a full gear 44 are mounted on the outside of the drive shaft 42. The assembly also includes an inclined conveyor belt 45 that drives the drive roller 43 and the driven rollers 1 41, 2 46, and 3 47. The full gear 44 is symmetrically arranged on both sides of the drive roller 43. The driven rollers 1 41 and 2 46 are at the same height, and the driven roller 3 47 is higher than the driven roller 2 46 and at the same height as the drive roller 43. The drive assembly 5 periodically drives... The rotation of the drive shaft 42 causes the drive roller 43 on the drive shaft 42 to rotate. When the drive roller 43 rotates, it drives the driven roller 1 41, driven roller 2 46 and driven roller 3 47 to rotate through the inclined conveyor belt 45, so that the inclined conveyor belt 45 rotates as a whole to transport the side plate. The drive roller 43 and driven roller 3 47 are horizontally aligned to ensure that the side plate is in a horizontal position after being transported, which is convenient for the pusher assembly 7 to push it to move. The horizontal alignment of driven roller 1 41 and driven roller 2 46 makes it convenient for the side plate to be submerged in water for heating. The height difference between driven roller 3 47 and driven roller 2 46 makes it convenient to transport and lift the side plate submerged in water.

[0053] Two sets of positioning components 9 are installed on the inner wall of the heating pool body 3. The two sets of positioning components 9 are respectively attached to the upper and lower sides of the inclined conveyor belt 45. The two sets of positioning components 9 are respectively located on the upper and lower sides of the driven roller 46. There are two positioning components 9 in one set. The distance between the two positioning components 9 in the same set is less than the length of the side plate to be processed. The positioning components 9 are used to press down the bend of the inclined conveyor belt 45, which shapes the bend without affecting the passage of the side plate.

[0054] The positioning component 9 specifically includes a bracket installed on the inner wall of the heating pool body 3 and a roller rotatably connected to the inner side of the bracket. The roller is in contact with the outer side of the inclined conveyor belt 45. The roller transforms the hard friction between the bracket and the inclined conveyor belt 45 into rolling friction. At the same time, the outer side of the inclined conveyor belt 45 is provided with a wear-resistant coating to improve the service life of the inclined conveyor belt 45.

[0055] The outer side of the inclined conveyor belt 45 is also provided with anti-slip texture, which can prevent the board from slipping when conveying the board and ensure that the board after soaking and softening can be conveyed up for loading.

[0056] The drive assembly 5 includes a mounting bracket 51 mounted on the heating tank body 3, a drive motor 52 mounted on the mounting bracket 51, a rotating shaft 53 passing through the heating tank body 3 and rotatably connected to its inner wall, and incomplete gear one 54 and incomplete gear two 55 mounted on the rotating shaft 53. Both incomplete gear one 54 and incomplete gear two 55 are provided with teeth, the circumference of which does not exceed half the circumference of incomplete gear one 54 and incomplete gear two 55. The circumference of the teeth on incomplete gear two 55 is greater than the circumference of the teeth on incomplete gear one 54. The intermittent engagement of the cleat with the full gear 44 is achieved. The output shaft of the drive motor 52 is connected to the rotating shaft 53 via a coupling. When the drive motor 52 starts, it drives the incomplete gear 1 54 and incomplete gear 2 55 on the rotating shaft 53 to rotate. The incomplete gear 1 54 intermittently engages with the full gear 44 on the drive shaft 42, causing the inclined conveyor belt 45 to stop after moving a fixed distance each time. When it stops moving, the incomplete gear 2 55 no longer engages with the pusher assembly 7. The pusher assembly 7 resets and moves down, then moves closer to the forming mold 2, which can push the side plate on the inclined conveyor belt 45 onto the lower metal heating plate 28.

[0057] The anti-reverse assembly 6 is a ratchet and pawl structure, specifically including a connecting spring 61 installed on the inner wall of the heating tank 3, a pawl 62 installed on the other side of the connecting spring 61, and a ratchet 63 installed on the full gear 44. The other side of the pawl 62 engages with the ratchet 63. When the incomplete gear 54 does not mesh with the full gear 44 on the drive shaft 42, in order to prevent the side plate on the inclined conveyor belt 45 from shifting, the ratchet 63 and the pawl 62 can prevent the drive shaft 42 from rotating in the opposite direction, ensuring that the plate on the inclined conveyor belt 45 has no displacement or shift, and ensuring the repeatability and positioning accuracy of the subsequent pushing action. To ensure the stability of the engagement between the pawl 62 and the ratchet 63, a retractable guide post is provided inside the connecting spring 61. The two ends of the guide post are connected to the inner wall of the heating tank 3 and the pawl 62, respectively.

[0058] The feeding assembly 7 includes a horizontal track 71 symmetrically mounted on the heating tank body 3, a rack plate 72 slidably mounted on the horizontal track 71, a connecting frame 73 mounted on the heating tank body 3, a support spring 74 connecting the rack plate 72 and the connecting frame 73, a sleeve 75 mounted on the rack plate 72, a movable plate 76 sliding up and down inside the sleeve 75, and a scraper 77 connecting the two movable plates 76. The rack plate 72 periodically engages with the incomplete gear 55, and the sleeve 75 rests against... A strip-shaped hole is provided on the inner wall of the side near the connecting frame 73. The bottom of the moving plate 76 and the side of the connecting frame 73 are set as mutually cooperating inclined surfaces. When the locking teeth 56 on the incomplete gear 2 55 first meshes with the rack plate 72, the locking teeth 56 on the incomplete gear 1 54 then meshes with the full gear 44 on the drive shaft 42. When the locking teeth 56 on the incomplete gear 2 55 do not mesh with the rack plate 72, the locking teeth 56 on the incomplete gear 1 54 also no longer mesh with the full gear 44 on the drive shaft 42.

[0059] When the drive motor 52 starts and drives the incomplete gear 1 54 and incomplete gear 2 55 on the rotating shaft 53 to rotate, the incomplete gear 2 55 first meshes with the rack plate 72, causing the sleeve 75 on the rack plate 72 to approach the connecting frame 73. After the moving plate 76 contacts the side of the connecting frame 73, and the scraper 77 on the moving plate 76 is lifted a short distance by the inclined surface, the incomplete gear 1 54 then meshes with the full gear 44 to transport the side plate. When the rotation reaches the incomplete gear 1 54 and incomplete gear 2 55... When the toothed plate 72 and the gear 44 are not engaged, it indicates that the previous side plate has been conveyed and the next side plate is stopped. At this time, the support spring 74 is reset and the moving plate 76 moves away from the connecting frame 73. The two inclined surfaces no longer abut against each other. Under the action of gravity, the scraper 77 moves down and contacts the surface of the inclined conveyor belt 45 and moves away from the connecting frame 73, sending the side plate 73 on the inclined conveyor belt 45 to the lower metal heating plate 28 for hot bending. This process is repeated to realize the automatic conveying of the plate without manual feeding, thus improving work efficiency.

[0060] The heating pool body has symmetrical notches 8 on both sides. The inner wall of the heating pool body 3 is equipped with heat insulation material. The notch 8 on one side makes it easy to put the heated plate into the heating pool body 2, and the notch 8 on the other side makes it easy to inspect the pushing component 7 and the driving component 5. The heat insulation material can reduce the heat loss in the heating pool body 3 and can better heat the plate.

[0061] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
