Description

Technical Field

[0001] The invention belongs to the technical field of metal processing and relates to a panel deburring device. Background Art

[0002] After stamping and cutting, burrs will form on the edge of the cut surface of the metal sheet. If the cut surface gap between the upper and lower dies is too large or too small, the height of the burr will increase. If the cut surface gap is too large, a triangular burr will be generated, and the burr thickness will increase. If the gap is too small, the burr will be thin and high, and secondary shearing will occur. For this reason, it is necessary to add a deburring process later. For example, Chinese patent [Patent No. 202120057156.9] discloses an automatic double-sided deburring machine for aluminum alloy panels, which includes an operating table and a grinding frame. The grinding frame is provided with a threaded rod and a second reciprocating motor inside. The threaded rod is provided with a driven gear and a second movable screw sleeve on the circumference of the side. The driven gear is located above the second movable screw sleeve. A moving rod is fixedly installed on both sides of the second movable screw sleeve. A lifting rod is fixedly installed on the bottom surface of the moving rod. The bottom surface of the lifting rod is fixedly connected to a mounting plate. A connecting rod is fixedly installed on the bottom surface of the mounting plate. A hydraulic rod is provided on the circumference of the connecting rod. A grinding wheel is provided at one end of the hydraulic rod. A drive gear is provided on the circumference of the motor shaft of the second reciprocating motor. However, this deburring machine has no adjustment mechanism and cannot adapt to panels of various sizes. Summary of the Invention

[0003] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a panel burr reduction device that can flatten the burrs on both sides of the panel and can adaptively adjust the uneven areas or wavy panels of the same panel.

[0004] The object of the present invention can be achieved by the following technical solutions: A panel deburring device, comprising a base, on which a feeding mechanism, a deburring mechanism, and a leveling mechanism are sequentially provided, characterized in that the feeding mechanism comprises a feeding table fixed to the base, a pushing assembly provided on the feeding table and capable of pushing a sheet forward, and a positioning assembly preventing the sheet from shifting left and right;

[0005] The cam is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate,

[0006] The leveling mechanism comprises a leveling frame, an upper leveling roller and a lower leveling roller. The leveling frame is fixed on the base, and the upper leveling roller and the lower leveling roller are both rotatably connected to the leveling frame.

[0007] Furthermore, the pushing assembly includes an L-shaped pushing rod and a pushing cylinder fixed in the feeding platform. A pushing straight hole is opened on the pushing platform. The upper end of the L-shaped pushing rod passes through the pushing straight hole, and the lower end of the L-shaped pushing rod is connected to the telescopic rod of the pushing cylinder.

[0008] Furthermore, the positioning assembly includes a fixed baffle, a movable baffle, and a positioning cylinder. A mounting block and a mounting seat are fixed on the feed table. The fixed baffle is fixed to the mounting block by bolts. The positioning cylinder is fixed on the mounting seat. A guide cylinder is fixed on the mounting seat. A guide rod passing through the guide cylinder is fixed on the movable baffle. The telescopic rod of the positioning cylinder is fixed on the movable baffle. The movable baffle is parallel to the fixed baffle. The positioning cylinder can drive the movable baffle close to or away from the fixed baffle.

[0009] Furthermore, the toggle assembly includes a strip-shaped sliding hole on the upper plate, a toggle block and a toggle fork sleeved on the horizontal axis, the burr-pressing wheel is embedded in the toggle groove on the toggle fork, a vertically arranged toggle rod is fixed on the upper surface of the toggle fork, a through hole for the toggle rod to pass through is opened on the toggle block, and the toggle rod passes upward through the strip-shaped sliding hole and out of the through hole of the toggle block.

[0010] Furthermore, a locking plate is fixed on the upper plate, and a horizontally arranged long locking hole is opened on the locking plate. A penetrating connecting hole is opened on the toggle block, and a locking bolt is passed through the connecting hole. The locking bolt passes through the locking hole and the connecting hole to fix the locking plate and the toggle block.

[0011] Furthermore, a guide plate is fixed to the front end of the square frame, and the guide plate is flush with the feeding platform.

[0012] Furthermore, the front end of the leveling frame is rotatably connected to a guide roller.

[0013] Before operation, the distance between the two deburring wheels needs to be adjusted to match the width of the sheet, so that the deburring wheels can flatten the burrs on both edges of the sheet. First, loosen the locking bolts to allow the toggle block to move horizontally along the strip slide hole. After moving to the desired position, tighten the bolts to secure the toggle block to the locking plate.

[0014] The sheet to be deburred is placed on the feed table. The feed mechanism's positioning assembly is activated, and the positioning cylinder pushes the movable baffle toward the fixed baffle, ultimately aligning the sheet's edges against the movable and fixed baffles. The pusher assembly's pusher cylinder is activated, causing the L-shaped pusher rod to propel the sheet forward. Guided by the guide plate, the sheet's front end enters the deburring mechanism. The sheet enters between the deburring roller and the deburring wheel. A spring forces the deburring wheel to press firmly against the sheet's edge, flattening any burrs. Because the deburring roller is actively driven by a motor, the sheet is squeezed forward by these rollers and into the leveling mechanism, where it is leveled by the upper and lower leveling rollers.

[0015] Compared with the existing technology, this panel burr pressing device has the following advantages:

[0016] 1. The adjustment seat can be automatically raised and lowered, so that the deburring wheel can rise and fall along the uneven edge of the sheet, ensuring that the burrs on the edge can be flattened.

[0017] 2. It has a toggle component that can drive the deburring wheel to move left and right to adapt to sheets of different widths. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0024] like Figure 1 As shown, a panel deburring device includes a base 1, on which a feeding mechanism, a deburring mechanism 5, and a leveling mechanism 6 are sequentially provided. The feeding mechanism includes a feeding table 2 fixed on the base 1, a pushing assembly 3 provided on the feeding table 2 for pushing the sheet forward, and a positioning assembly 4 for preventing the sheet from shifting left and right.

[0025] like Figure 2 As shown, the pushing assembly 3 includes an L-shaped pushing rod 31 and a pushing cylinder 32 fixed in the feeding platform 2. A pushing straight hole 33 is opened on the pushing platform. The upper end of the L-shaped pushing rod 31 passes through the pushing straight hole 33, and the lower end of the L-shaped pushing rod 31 is connected to the telescopic rod of the pushing cylinder 32.

[0026] The positioning assembly 4 includes a fixed baffle 41, a movable baffle 42, and a positioning cylinder 43. A mounting block 44 and a mounting seat 45 are fixed on the feed table 2. The fixed baffle 41 is fixed to the mounting block 44 by bolts. The positioning cylinder 43 is fixed to the mounting seat 45. A guide cylinder 46 is fixed on the mounting seat 45. A guide rod 47 passing through the guide cylinder 46 is fixed on the movable baffle 42. The telescopic rod of the positioning cylinder 43 is fixed on the movable baffle 42. The movable baffle 42 is parallel to the fixed baffle 41. The positioning cylinder 43 can drive the movable baffle 42 to approach or move away from the fixed baffle 41.

[0027] like Figure 3As shown, the deburring mechanism 5 includes a support frame 51 fixed on the base 1, a motor 52 and a square frame 53 fixed on the support frame 51, and a deburring steel roller 54. The deburring steel roller 54 is horizontally rotatably connected in the square frame 53. One end of the deburring steel roller 54 passes through the square frame 53 and is connected to the motor 52 through a coupling. Grooves 55 are opened on both side plates of the square frame 53. Adjustment seats 56 that slide up and down along the grooves 55 are provided in the grooves 55. A horizontal axis 5 is passed through the two adjustment seats 56. 7. A burr pressing wheel 58 that can be translated along the horizontal axis 57 is provided on the horizontal axis 57. The upper plate 511 of the square frame 53 is fixed to the two side plates by bolts. A limit rod 59 is vertically fixed on the adjustment seat 56. A spring 510 is sleeved on the limit rod 59. The upper end of the limit rod 59 passes through the upper plate 511, and the lower end of the spring 510 rests on the adjustment seat 56. The upper end of the spring 510 rests on the lower surface of the upper plate 511. A toggle component 7 that can toggle the burr pressing wheel 58 to move horizontally along the horizontal axis 57 is provided on the upper plate 511.

[0028] The toggle assembly 7 includes a strip-shaped sliding hole 71 on the upper plate 511, a toggle block 72 and a toggle fork 73 sleeved on the horizontal axis 57. The burr-pressing wheel 58 is embedded in the toggle groove of the toggle fork 73. A vertically arranged toggle rod 74 is fixed to the upper surface of the toggle fork 73. A through hole is opened on the toggle block 72 for the toggle rod 74 to pass through. The toggle rod 74 passes upward through the strip-shaped sliding hole 71 and out of the through hole of the toggle block 72.

[0029] A locking plate 75 is fixed to the upper plate 511. A horizontally arranged, elongated locking hole 76 is defined in the locking plate 75. A connecting hole is defined through the toggle block 72. A locking bolt 77 is inserted through the connecting hole. The locking bolt 77 passes through the locking hole 76 and the connecting hole to secure the locking plate 75 to the toggle block 72. A guide plate 512 is secured to the front end of the square frame 53. The guide plate 512 is flush with the feed table 2. The horizontal position of the deburring wheel 58 can be adjusted by manually pushing the toggle block 72. Once the desired position is reached, tighten the locking bolt 77 to secure the toggle block 72 to the locking plate 75, preventing the deburring wheel 58 from shifting sideways during operation.

[0030] like Figure 4 As shown, the leveling mechanism 6 includes a leveling frame 61, an upper leveling roller 62 and a lower leveling roller 63. The leveling frame 61 is fixed on the base 1. The upper leveling roller 62 and the lower leveling roller 63 are both rotatably connected to the leveling frame 61. The front end of the leveling frame 61 is rotatably connected to a guide roller 64.

[0031] Workflow: Before operation, the spacing between the two deburring wheels 58 must be adjusted to match the width of the sheet, allowing the deburring wheels 58 to flatten the burrs on both edges of the sheet. First, loosen the locking bolt 77 to allow the toggle block 72 to move along the strip-shaped slide hole 71. After moving to the desired position, tighten the bolt to secure the toggle block 72 to the locking plate 75.

[0032] The sheet to be deburred is placed on the feed table 2. The positioning assembly 4 of the feed mechanism is activated, and the positioning cylinder 43 pushes the movable baffle 42 toward the fixed baffle 41, ultimately forcing the sheet's two sides to abut against the movable baffle 42 and the fixed baffle 41, respectively. The push cylinder 32 of the push assembly 3 is activated, causing the L-shaped push rod 31 to push the sheet forward. Guided by the guide plate 512, the front end of the sheet enters the deburring mechanism 5. The sheet enters between the deburring steel roller 54 and the deburring wheel 58. Due to the action of the spring 510, the deburring wheel 58 presses firmly against the sheet's edge, flattening any burrs. Since the deburring steel roller 54 is actively driven by the motor 52, the sheet is squeezed forward by the deburring steel roller 54 and the deburring wheel 58 and enters the leveling mechanism 6, where the upper and lower leveling rollers 62 and 63 level the sheet.

[0033] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
