Description

Technical Field

[0001] This application relates to the field of sheet metal processing technology, and in particular to a sheet metal trimming device. Background Technology

[0002] Cosmetic booths come in a variety of shapes and are made of different materials, such as acrylic, metal, and wood.

[0003] For acrylic booths, the current manufacturing method usually involves cutting a single piece of acrylic sheet into multiple pieces of corresponding shapes, and then splicing these pieces together to form the booth structure of the specified shape. For booths with special shapes, such as trapezoids, some of the panels have sloping sides. For these panels, after processing, one edge needs to be sanded and trimmed to make the beveled edge a smooth surface for easier use later.

[0004] The current method for trimming the edges of boards typically involves a worker holding the board in one hand while using a specialized grinding device to repeatedly grind the edges until they are smooth. However, in actual processing, this method requires the worker to repeatedly move the grinding device while constantly observing the bevel of the board. The overall operation is cumbersome, and the processing quality cannot be guaranteed, thus requiring improvement. Utility Model Content

[0005] In order to improve the convenience of the processing while ensuring the quality of trimming the board material, this application provides a board trimming device.

[0006] This application provides a sheet metal trimming device, which adopts the following technical solution:

[0007] A sheet metal trimming device includes a base, a support plate mounted on the base, a grinding rod mounted on the base for grinding the inclined surface of the sheet metal, and a drive component mounted on the base for driving the grinding rod to rotate. The support plate has a triangular groove for embedding the inclined surface of the sheet metal to be ground, and the sheet metal slides along the length of the triangular groove. The support plate also has a clearance groove that communicates with the triangular groove. The end of the grinding rod away from the drive component passes through the clearance groove and extends into the triangular groove.

[0008] By adopting the above technical solution, the entire board is placed on the support plate, and the inclined surface of the board to be polished is inserted into the triangular groove. The board is guided and limited by the inner wall of the triangular plate. Then, the polishing rod is driven to rotate by the drive component, and the board is pushed along the length of the triangular groove. During the movement of the board, the inclined surface of the board can be polished by the polishing rod. During the polishing process, the board is limited by the support plate and the inner wall of the triangular groove, thereby ensuring the polishing quality of the board. The overall operation is simple and convenient.

[0009] Preferably, the support plate includes a base plate placed on the machine base, an inclined plate fixed on the base plate, and a guide plate fixed on the side of the inclined plate near the base plate. There is an angle between the inclined plate and the base plate, and there is an angle between the guide plate and the inclined plate. The triangular groove is formed at the angle between the guide plate and the inclined plate. The clearance groove divides the guide plate into two parts from the middle of the guide plate along its length. The inclined plate is used to place the plate material, and the side of the guide plate facing the inclined plate is used to abut against the inclined surface of the plate material. The machine base is provided with a clamping assembly for clamping and positioning the base plate.

[0010] By adopting the above technical solution, the clamping components clamp and position the base plate during use. On the one hand, this achieves a detachable connection of the entire support plate, making it convenient for staff to replace support plates with different triangular groove sizes according to usage needs. On the other hand, it positions the support plate to prevent it from moving on the machine base during grinding, thus affecting the grinding quality of the material.

[0011] Preferably, the clamping assembly includes two pressure rods rotatably connected to the base, a drive structure for driving the two pressure rods to rotate synchronously, and a positioning post fixed to the base. The two pressure rods are symmetrically arranged at both ends of the base plate along its length. The base plate has positioning holes for embedding the positioning post, and the pressure rods are used to press the base plate to prevent the positioning post from dislodging from the positioning hole.

[0012] By adopting the above technical solution, the horizontal positioning of the base plate is achieved through the cooperation of the positioning column and the positioning hole, and the vertical positioning of the base plate is achieved through the setting of the drive structure and the pressure rod, thereby realizing the fixation of the base plate.

[0013] Preferably, the drive structure includes a drive rod slidably mounted on the base, a rack fixed on the drive rod, a gear rotatably mounted on the base, a connecting shaft coaxially and fixedly connected to the gear, a handwheel fixed to the end of the connecting shaft, and a linkage rod disposed between the drive rod and the pressure rod. The rack and the gear mesh, and there are two linkage rods symmetrically connected to the two sides of the top end of the drive rod. One end of the linkage rod is rotatably connected to the drive rod, and the other end of the linkage rod is rotatably connected to the end of the pressure rod away from the base plate.

[0014] By adopting the above technical solution, during use, the operator rotates the handwheel to drive the connecting shaft to rotate, which in turn drives the gear to rotate synchronously. The rotation of the gear drives the rack to slide, which in turn drives the drive rod to slide. Under the action of the two linkage rods, the sliding of the drive rod can drive the two pressure rods to rotate synchronously, thereby achieving the purpose of pressing the base plate onto the machine base.

[0015] Preferably, a reinforcing rib is provided between the base plate and the inclined plate. A plurality of reinforcing ribs are provided, and the plurality of reinforcing ribs are evenly spaced along the length of the base plate. One side of the reinforcing rib is fixedly connected to the base plate, and the other side of the reinforcing rib is fixedly connected to the side wall of the inclined plate.

[0016] By adopting the above technical solution, the strength of the inclined plate connection structure is increased by setting several reinforcing ribs during use, thereby ensuring the stability of the support plate during use.

[0017] Preferably, the machine base has a discharge hole, which is arranged corresponding to the clearance groove. The grinding rod passes through the discharge hole and then into the clearance groove. The machine base has a collection groove, which contains a collection box for collecting waste material. The collection box is arranged corresponding to the discharge hole.

[0018] By adopting the above technical solution, during use, the grinding debris generated on the board is allowed to fall into the collection box through the dropping hole and the collection box during the grinding process. The collection box collects the waste debris for subsequent cleaning by the staff.

[0019] Preferably, the base is further provided with a bamboo tube, one end of which is provided with an air nozzle that blows air toward the polishing rod.

[0020] By adopting the above technical solution, the direction of the air nozzle can be adjusted and positioned by utilizing the fact that the bamboo tube can rotate in all directions and be positioned, which is convenient for use; air is blown into the grinding rod through the air nozzle, thereby blowing the debris adhering to the grinding rod into the material discharge hole.

[0021] Preferably, the base is also provided with an air gun, and the rear end of the air gun is connected to an external air tank via an air pump.

[0022] By adopting the above technical solution, during the sanding process, the staff simultaneously use an air gun to blow air onto the inclined surface of the board to blow away the debris, so that the staff can observe and judge the sanding status of the board, thereby ensuring the sanding quality of the board.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By placing the entire board on the support plate and inserting the inclined surface of the board to be sanded into the triangular groove, the board is limited. Then, the sanding rod is driven to rotate by the drive component, while the board is pushed along the length of the triangular groove. During the movement of the board, the inclined surface of the board can be sanded by the sanding rod. During the sanding process, the board is limited by the support plate and the inner wall of the triangular groove, thereby ensuring the sanding quality of the board. The overall operation is simple and convenient.

[0025] 2. By setting up the clamping components, on the one hand, the support plate can be detachably connected as a whole, making it convenient for staff to replace support plates with different triangular groove sizes according to usage needs; on the other hand, the support plate is positioned to prevent it from moving on the machine base during the grinding process, which would affect the grinding quality of the material.

[0026] 3. By using the air nozzle and air gun together, air is blown into the debris generated on the board during the sanding process, and the debris is blown into the collection box. This allows the staff to observe and judge the processing status of the board in real time, which is more conducive to ensuring the processing quality of the board. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail.

[0034] This application discloses a sheet metal trimming device.

[0035] Reference Figure 1 and Figure 2 A sheet metal trimming device includes a horizontally placed base 1, a support plate 2, a grinding rod 3, and a drive component 4 disposed on the base 1. The support plate 2 is used to place the sheet metal 9 to be ground, the grinding rod 3 is used to grind the sheet metal 9, and the drive component 4 is used to drive the grinding rod 3 to rotate. In this embodiment, the drive component 4 is preferably a servo motor. The servo motor is installed on the bottom side of the table surface of the base 1. A material drop hole 11 is opened in the vertical direction on the table surface of the base 1. The output shaft of the servo motor is coaxially connected to the input shaft of the gearbox. The output shaft of the gearbox is coaxially fixedly connected to the bottom end of the grinding rod 3. The top end of the grinding rod 3 passes through the material drop hole 11 and extends to the top of the table surface of the base 1.

[0036] Reference Figure 1 and Figure 3 The support plate 2 is composed of a base plate 21, an inclined plate 22 and a guide plate 23. The base plate 21 is placed on the table of the machine base 1. The inclined plate 22 is inclined and set above the base plate 21, that is, there is an angle between the inclined plate 22 and the base plate 21. A number of reinforcing ribs 26 are provided between the inclined plate 22 and the base plate 21. The reinforcing ribs 26 are evenly spaced along the length of the base plate 21. The two sides of the reinforcing ribs 26 are fixed to the inclined plate 22 and the base plate 21 respectively. The guide plate 23 is fixed on the side of the inclined plate 22 away from the base plate 21, and there is also an angle between the guide plate 23 and the inclined plate 22. In this application, a triangular groove 24 is formed at the angle between the guide plate 23 and the inclined plate 22.

[0037] Reference Figure 1 and Figure 3 An avoidance groove 25 is provided in the middle of the guide plate 23 along its length. The avoidance groove 25 divides the guide plate 23 into two parts and is connected to the triangular groove 24. The top of the grinding rod 3 passes through the material drop hole 11 and then enters the avoidance groove 25. The outer side wall of the grinding rod 3 located in the avoidance groove 25 is located in the triangular groove 24. The angle of the triangular groove 24 matches the setting angle of the inclined surface of the plate 9 to be processed.

[0038] Reference Figure 1 and Figure 3When using this tool, place the board 9 on the inclined plate 22 with the inclined surface of the board 9 to be sanded facing the triangular groove 24. Then push the board 9 to fit against the inclined plate 22 and move it down until the inclined surface of the board 9 is embedded in the triangular groove 24 and the inclined surface of the board 9 abuts against the side wall of the guide rod facing the inclined plate 22. Then push the board 9 along the length of the triangular groove 24. Under the support and limiting action of the guide plate 23 and the inclined plate 22, the inclined surface of the board 9 to be processed slides in the triangular groove 24. During the sliding process, the board 9 can be sanded by rotating the sanding rod 3. The tool is simple and convenient to use and makes it easy for workers to control the accuracy of sanding, thereby ensuring the processing quality.

[0039] Reference Figure 1 and Figure 4 A clamping assembly 5 is also provided on the base 1. The clamping assembly 5 is used to clamp and fix the base plate 21 on the table surface of the base 1. The clamping assembly 5 includes two pressure rods 51, a drive structure 52 and a positioning post 53. The two pressure rods 51 are symmetrically arranged at both ends of the base plate 21 in the length direction and are rotatably connected to the base 1. The drive structure 52 is used to drive the two pressure rods 51 to rotate synchronously. The positioning post 53 is welded and fixed on the table surface of the base 1. A positioning hole 211 is correspondingly opened on the base plate 21, and the positioning post 53 is inserted into the positioning hole 211.

[0040] Reference Figure 1 and Figure 4 In use, first align the positioning hole 211 on the base plate 21 with the positioning post 53, then lower the base plate 21 so that it is placed on the table of the machine base 1, and insert the positioning post 53 into the positioning hole 211. The positioning post 53 and the inner wall of the positioning hole 211 will cooperate to position the base plate 21 horizontally. Then, the drive structure 52 will drive the two pressure rods 51 to rotate and press down synchronously, so that the two pressure rods 51 will press the base plate 21 firmly on the table of the machine base 1. That is, the pressure rods 51 will position the base plate 21 vertically. This will enable the detachable connection of the support plate 2, and also make it convenient for the staff to replace the support plate 2 with different angles between the guide plate 23 and the inclined plate 22 according to the needs of use.

[0041] Reference Figure 4 and Figure 5The drive structure 52 includes a drive rod 521, a rack 522, a gear 523, a connecting shaft 524, a handwheel 525, and a linkage rod 526. The drive rod 521 is slidably connected to the base 1 in the vertical direction. The rack 522 is fixed to the side wall of the drive rod 521 by bolts, and the length direction of the rack 522 is parallel to the sliding direction of the drive rod 521. The gear 523 is rotatably mounted on the base 1 and meshes with the rack 522. One end of the connecting shaft 524 is coaxially fixedly connected to the gear 523, and the other end of the connecting shaft 524 passes through the base 1 and is connected to the handwheel 525. The handwheel 525 is located on the outside of the base 1 and is used to drive the connecting shaft 524 to rotate. The number of linkage rods 526 is the same as that of the pressure rods 51 and they correspond one-to-one. One end of the linkage rod 526 is hinged to the top side wall of the drive rod 521, and the other end of the linkage rod 526 is hinged to the bottom end of the pressure rod 51 on the corresponding side.

[0042] Reference Figure 4 and Figure 5 In use, the operator rotates the handwheel 525, which in turn rotates the gear 523 under the action of the connecting shaft 524. The rotation of the gear 523 drives the rack 522 to slide vertically. In this embodiment, when the rack 522 moves upward, it drives the drive rod 521 to move upward. With the cooperation of the linkage rod 526, the upward movement of the drive rod 521 simultaneously drives the pressure rod 51 to rotate and open, thus enabling the disassembly of the support plate 2. When the rack 522 moves downward, it drives the drive rod 521 to move downward. With the cooperation of the linkage rod 526, the downward movement of the linkage rod 526 drives the pressure rod 51 to rotate and press down, thereby achieving the clamping and limiting of the support plate 2. The overall use is simple and convenient.

[0043] Reference Figure 1 and Figure 3 During the sanding process of board 9, in order to prevent the debris generated on board 9 from adhering to the sanding rod 3 and affecting the sanding efficiency, a bamboo tube 6 is also provided on the machine base 1. The bottom end of the bamboo tube 6 is detachably mounted on the table of the machine base 1, and an air nozzle 7 is installed at the top of the bamboo tube 6. The air nozzle 7 is connected to the external air source through a ventilation hose, which is set inside the bamboo tube 6. The air nozzle 7 is set facing the sanding rod 3. In use, by utilizing the positioning characteristic of the bamboo tube 6 after universal rotation, it is easy for the operator to adjust the orientation of the air nozzle 7 until the air nozzle 7 faces the sanding rod 3. Then, air can be blown through the air nozzle 7 to blow the debris adhering to the sanding rod 3 into the material drop hole 11, thereby ensuring the normal sanding effect of the sanding rod 3.

[0044] Reference Figure 1In addition, during the sanding process of board 9, debris inevitably adheres to the inclined surface of board 9, which can easily affect the staff's observation and judgment of the sanding status of board 9. In order to clean the debris from the inclined surface of board 9, an air gun 8 is placed on the base 1. The rear end of the air gun 8 is connected to an external air tank through an air pump. When in use, the staff pushes board 9 along the length of the triangular groove 24 with one hand and holds the air gun 8 with the other hand to blow air into the contact gap between the triangular groove 24 and board 9, thereby blowing away the debris adhering to board 9, so as to facilitate the staff's observation and judgment of the sanding status of board 9.

[0045] Reference Figure 1 and Figure 2 Meanwhile, to facilitate the cleaning of debris on the machine base 1, a collection groove 12 is provided on the side wall of the machine base 1. A collection box 13 is set in the collection groove 12. The upper end of the collection box 13 is open, and the opening of the collection box 13 is located directly below the discharge hole 11. A handle is provided on the outer wall of the collection box 13. When in use, the debris at the grinding rod 3 falls into the collection box 13 along the discharge hole 11 under the action of the air nozzle 7. The debris can then be collected by the collection box 13. Afterwards, the staff can pull out the collection box 13 and clean the debris in the collection box 13 to the designated location.

[0046] Reference Figure 1 and Figure 2 In practical applications, the debris generated during the grinding of board 9 will inevitably fall onto the table of machine base 1 under the action of air gun 8 and air nozzle 7. After grinding, the staff can also use air gun 8 to blow the debris on the table of machine base 1 into the discharge hole 11, so that the debris can be cleaned and collected through collection box 13.

[0047] The implementation principle of this application embodiment is as follows: In use, first, according to the angle of the inclined surface of the plate 9 to be ground, select a support plate 2 with a matching triangular groove 24. Then, place the support plate 2 on the machine base 1 and insert the positioning pin 53 into the positioning hole 211. Next, the operator cranks the handwheel 525 to synchronously rotate and press down the two pressure rods 51, thereby fixing the support plate 2. Then, place the plate 9 to be ground on the inclined plate 22, with the inclined surface of the plate 9 facing the guide plate 23. Then, push the plate 9 so that the end of the plate 9 with the inclined surface to be ground is embedded in the triangular groove 24. The drive unit 4 is activated to rotate the grinding rod 3. At the same time, the operator pushes the board 9 with one hand, causing the inclined surface of the board 9 to slide along the triangular groove 24. With the other hand, the operator holds the air gun 8 and blows air into the gap between the inclined surface of the board 9 and the triangular groove 24. During the movement of the board 9, the inclined surface of the board 9 can be ground by rotating the grinding rod 3. During the grinding process, the air gun 8 and the air nozzle 7 work together to blow the debris generated on the board 9 into the discharge hole 11 and drop it into the collection box 13. The whole process is simple and convenient, and at the same time, the grinding quality is ensured.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
