Description

Technical Field

[0001] This utility model relates to the field of sign production technology, specifically a sign production cutting machine. Background Technology

[0002] Signage is an important part of road infrastructure. For example, directional signs guide vehicles and pedestrians to pass correctly, prohibitory signs restrict specific traffic behaviors, and warning signs remind people to pay attention to dangerous road conditions. Most signs are made of aluminum alloy, which is lightweight and corrosion resistant. However, in the production of signs, aluminum alloy plates often need to be cut into the shape of the signs, and this cutting process requires the use of a plate cutting machine.

[0003] Existing technologies, such as the HS-6 manual shearing machine, mainly include components such as an upper blade, a lower blade, and a handle. When the handle is manually operated, the force is transmitted to the upper blade through a lever mechanism, causing the upper blade to reciprocate relative to the fixed lower blade. The upper and lower blades have a reasonable blade gap. When the sheet metal is placed between the blades, the manually applied force causes the blades to apply shearing force to the sheet metal, using the shearing force to break and separate the sheet metal to the required dimensions.

[0004] The aforementioned panel cutting machines have some problems in actual use. For example, during the cutting process, it is necessary to constantly adjust the position of the aluminum alloy sheet and position it, which is cumbersome and lacks continuity. Therefore, we propose a panel cutting machine for sign production. Utility Model Content

The sliding plate is located between the workbench and the fixed plate. The lower mold is located in the middle of the upper surface of the workbench, and the upper mold is located in the middle of the lower surface of the sliding plate.

The output shaft of the motor is fixedly connected to the left end of the lead screw on the rear left side.

[0011] Furthermore, the sheet material conveying and correction mechanism also includes chutes, which are evenly distributed on the upper surface of the workbench. The lower sides of the four rubber pillars are located inside the longitudinally adjacent chutes, which partially enclose the left and right sides of the aluminum alloy sheet material.

[0012] Furthermore, it also includes clearance openings, which are symmetrically opened on the upper surface of the sliding plate. The interior of the two clearance openings are slidably connected to the outer surface of the vertically adjacent fixed frame to realize the clearance function.

The output shaft of the stamping cylinder is fixedly connected to the middle of the upper surface of the sliding plate. The oil inlet of the stamping cylinder is connected to an external oil pump to provide power for stamping and cutting the plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The board cutting machine produced by this sign has the following advantages:

[0016] This structure uses a screw drive mechanism to adjust the spacing between the rubber columns.

The aluminum alloy sheet can be inserted from the rear into the space between the sliding plate 4 and the worktable 1. At this time, the first guide wheel 7 adheres to the upper surface of the aluminum alloy sheet with appropriate force, and the third guide wheel 10 adheres to the lower surface of the aluminum alloy sheet with appropriate force, and pushes the aluminum alloy sheet forward until the aluminum alloy sheet moves between the upper mold 14 and the lower mold 13. At this time, the external oil pump can be adjusted, the stamping cylinder 11 operates, and the telescopic end of the stamping cylinder 11 extends and retracts once, so that the upper mold 14 extends into the interior of the lower mold 13, and the aluminum alloy sheet between the upper mold 14 and the lower mold 13 is cut once by stamping to complete the cutting operation. Then the aluminum alloy sheet can be pushed forward.

[0025] The sheet metal conveying and correcting mechanism 6 includes a fixed frame 61, lead screws 62, clamping plates 63, rubber columns 64, and rotating rods 65. The fixed frames 61 are symmetrically fixed to the upper surface of the fixed plate 5. Lead screws 62 are symmetrically rotatably connected between the left and right inner walls of the two fixed frames 61. A rotating rod 65 is fixedly connected between every two laterally adjacent lead screws 62. A clamping plate 63 is threaded onto the external thread surface of every two longitudinally adjacent lead screws 62. Rubber columns 64 are symmetrically rotatably connected to the lower surfaces of the two clamping plates 63. The thread direction of the two lead screws 62 on the left is opposite to that of the two lead screws 62 on the right. The sheet metal conveying and correcting mechanism 6 also includes a synchronous pulley 66, a synchronous belt 67, and an electric... The machine 68 has two lead screws 62 on the right side, each with a timing pulley 66 fixedly connected to its right end. The two timing pulleys 66 are connected by a timing belt 67. A motor 68 is located on the rear left side of the fixed frame 61 on the left side. The output shaft of the motor 68 is fixedly connected to the left end of the lead screw 62 on the rear left side.

The lower sides of the four rubber pillars 64 are located inside the longitudinally adjacent slide 69. It also includes clearance openings 8, which are symmetrically opened on the upper surface of the sliding plate 4. The interiors of the two clearance openings 8 are respectively connected to the outer surface of the vertically adjacent fixed frame 61.

The middle of the front side of the sliding plate 4 is rotatably connected to the second guide wheel 9. The upper surface of the worktable 1 has evenly distributed grooves, and the interior of each of the four grooves is rotatably connected to the third guide wheel 10. The front side of the worktable 1 has a discharge plate 12. The sign is made of aluminum alloy. When using this cutting machine, the width of the aluminum alloy raw material can be adjusted appropriately by the controller 15. The motor 68 runs, and the output shaft of the motor 68 rotates in both directions, thereby driving the lead screw 62 on the left rear side to rotate in both directions, thereby driving the two lead screws 62 and the rotating rod 65 on the rear side to rotate, and then through the synchronous belt pulley 66 and the synchronous... The belt 67 synchronously drives the two lead screws 62 and the rotating rod 65 to rotate synchronously. The two lead screws 62 on the front side and the two lead screws 62 on the rear side rotate in opposite directions, thereby driving the two clamping plates 63 to move synchronously towards or away from the center of the worktable 1. This adjusts the position of the four rubber pillars 64 and appropriately adjusts the distance between the two rubber pillars 64 on the left and the two rubber pillars 64 on the right. During the pushing process, the two rubber pillars 64 on the left and the two rubber pillars on the right clamp the aluminum alloy plate and push it forward. At this time, the cut and shaped sign moves forward until the second guide wheel 9 pushes the shaped sign off the aluminum alloy plate and it falls onto the discharge plate 12 for discharge.

[0026] The working principle of the plate cutting machine for sign production provided by this utility model is as follows: The signs are mainly made of aluminum alloy. When using this plate cutting machine, the width of the aluminum alloy raw material can be appropriately adjusted by the controller 15, the motor 68 runs, and the output shaft of the motor 68 rotates in both directions, thereby driving the left rear lead screw 62 to rotate in both directions, which in turn drives the two rear lead screws 62 and the rotating rod 65 to rotate. Then, through the synchronous pulley 66 and the synchronous belt 67, the two lead screws 62 and the rotating rod 65 are driven to rotate synchronously. The two front lead screws 62 and the two rear lead screws 62 rotate in both directions, thereby driving the two clamping plates 63 to move synchronously towards or away from the center of the worktable 1, thereby adjusting the position of the four rubber columns 64, and appropriately adjusting the distance between the two left rubber columns 64 and the two right rubber columns 64. After the adjustment is completed, the aluminum alloy sheet can be cut from the rear. Inserted between the sliding plate 4 and the worktable 1, the first guide wheel 7 adheres to the upper surface of the aluminum alloy sheet with appropriate force, and the third guide wheel 10 adheres to the lower surface of the aluminum alloy sheet with appropriate force, pushing the aluminum alloy sheet forward. During the pushing process, the two rubber pillars 64 on the left and the two rubber pillars 64 on the right clamp the aluminum alloy sheet and push it forward until the aluminum alloy sheet moves between the upper mold 14 and the lower mold 13. At this time, the external oil pump can be adjusted, the stamping cylinder 11 operates, and the telescopic end of the stamping cylinder 11 extends and retracts once, so that the upper mold 14 extends into the interior of the lower mold 13, and the aluminum alloy sheet between the upper mold 14 and the lower mold 13 is cut once by stamping to complete the cutting operation. Then the aluminum alloy sheet can be pushed forward, and the cut and shaped sign moves forward until the second guide wheel 9 pushes the shaped sign on the aluminum alloy sheet out and falls onto the discharge plate 12 for discharge.

[0027] It is worth noting that the controller 15 disclosed in the above embodiments is specifically model STM32F407. The motor 68 and the stamping cylinder 11 can be freely configured according to the actual application scenario. It is recommended to use a 130BL model motor for the motor 68 and a DG-J80C model hydraulic cylinder for the stamping cylinder 11. The controller 15 controls the operation of the motor 68 using methods commonly used in the prior art.
