Description

Technical Field

[0001] This utility model relates to the field of trolley case technology, specifically a trolley case frame forming device. Background Technology

[0002] The frame of a suitcase is usually made of silver-white metal strips. By adding a metallic luster, the texture of the suitcase can be improved. When making the frame of a suitcase, a corresponding forming device is required. The existing forming device is usually manually bent by workers according to the mold, which is not only inefficient, but also the bending effect of the metal strip is not ideal, making it difficult to meet production needs. Utility Model Content

[0003] The purpose of this utility model is to provide a trolley case frame forming device, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The trolley case frame forming device includes a base, on which a forming mold is provided. A pressing mechanism is provided on the upper surface of the base and on one side of the forming mold. The pressing mechanism includes a fixing block on the base, a pressure block on one side of the fixing block, and two guide rods slidably connected to the fixing block on one side of the pressure block. A stop block is provided at the end of the guide rod away from the pressure block. A spring is sleeved on the guide rod and located between the fixing block and the stop block. A cam is rotatably connected to the fixing block, and the outer surface of the cam is always in contact with the pressure block. The cam has a handle at one end, and the upper surfaces of the four corners of the forming mold are respectively provided with bending mechanisms. The bending mechanism includes a rotating shaft that passes through the base and the forming mold. The lower surface of the base is provided with a reduction motor for driving the rotating shaft to rotate. The upper end of the rotating shaft is provided with a mounting plate. The upper surface of the mounting plate is provided with a sleeve. The mounting plate has a through groove. The inner side of the through groove has a slot. The mounting plate also includes a pressure roller that is slidably connected to the through groove and the slot. The sleeve is provided with a compression spring. The lower end of the pressure roller is set as an incline. The forming mold is provided with a guide plate. The upper surface of the guide plate is inclined.

[0005] Preferably, the outer surface of the cam is provided with a rubber layer.

[0006] Preferably, the molding die has a long side and a short side, the pressure block is located at the middle position of the long side of the molding die, and the length of the pressure block is not less than one-third of the length of the long side of the molding die.

[0007] Preferably, the inner surface of the pressure block is provided with a rubber layer.

[0008] Preferably, the height of the forming mold is higher than the height of the metal strip surrounding the outer surface of the forming mold.

[0009] The beneficial effects of this utility model are:

[0010] When using this type of trolley case frame forming device, the operator only needs to be responsible for feeding, pressing and unloading the metal strip. The bending of the metal strip is completed by the rotation of the pressure roller controlled by the geared motor, which can reduce labor intensity and improve processing efficiency. At the same time, since the pressure roller can move from the base to the guide plate, when the pressed metal strip is released by the pressure block, there are no parts blocking the metal strip, so the bent metal strip can be easily removed, making it convenient to use.

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0017] like Figure 1-4As shown, a trolley case frame forming device includes a base 1, a forming mold 2 on the base 1, and a pressing mechanism on the upper surface of the base 1 and one side of the forming mold 2. The pressing mechanism includes a fixing block 3 on the base 1, a pressure block 4 on one side of the fixing block 3, and two guide rods 5 slidably connected to the fixing block 3 on one side of the pressure block 4. A stop block 6 is provided at the end of the guide rod 5 away from the pressure block 4. A spring 7 is sleeved on the guide rod 5 and is located between the fixing block 3 and the stop block 6. A cam 8 is rotatably connected to the fixing block 3. The outer surface of the cam 8 is always in contact with the pressure block 4, and a handle is provided at one end of the cam 8. Hand 9, the upper surfaces of the four corners of the forming mold 2 are respectively provided with bending mechanisms. The bending mechanism includes a rotating shaft 10 that passes through the base 1 and the forming mold 2. The lower surface of the base 1 is provided with a reduction motor 11 for driving the rotating shaft 10 to rotate. The upper end of the rotating shaft 10 is provided with a mounting plate 12. The upper surface of the mounting plate 12 is provided with a sleeve 13. The mounting plate 12 has a through groove. The inner side of the through groove has a slot. It also includes a pressure roller 14 that is slidably connected to the through groove and the slot. The sleeve 13 is provided with a compression spring 15. The lower end of the pressure roller 14 is set as an inclined surface. The forming mold 2 is provided with a guide plate 16. The upper surface of the guide plate 16 is inclined.

[0018] The frame of the suitcase is made of bent metal strip 17. After bending, the two ends of the metal strip 17 are welded together to complete the frame forming.

[0019] Before bending the metal strip 17, first place the metal strip 17 on one side of the forming mold 2, and position the metal strip 17 between the forming mold 2 and the pressure block 4. The narrower side of the metal strip 17 contacts the upper surface of the base 1, and the wider side of the metal strip 17 contacts the side of the forming mold 2. Then, rotate the cam 8 on the fixing block 3 by rotating the handle 9. When the cam 8 pushes the pressure block 4 to the position furthest from the fixing block 3, the metal strip 17 can be firmly pressed against the side of the forming mold 2. At the same time, under the action of the elasticity of the spring 7 and the friction between the cam 8 and the pressure block 4, the position of the cam 8 and the pressure block 4 will remain unchanged, thereby ensuring that the pressure block 4 can continuously press the metal strip 17 onto the forming mold 2.

[0020] After fixing the metal strip 17, first control the two geared motors 11 closest to the metal strip 17 to operate. One geared motor 11 moves counterclockwise, and the other geared motor 11 moves clockwise, as follows: Figure 2As shown, when the geared motor 11 drives the rotating shaft 10 to rotate through its output end, the rotating shaft 10 drives the mounting plate 12 to rotate, and drives the sleeve 13 and pressure roller 14 on the mounting plate 12 to rotate. The pressure roller 14 can move along the upper surface of the guide plate 16. When the pressure roller 14 moves to the uppermost end of the guide plate 16, as the geared motor 11 continues to drive the pressure roller 14 to rotate, the pressure roller 14 can move from above the guide plate 16 to a position beyond above the guide plate 16, and compress the spring 1 inside the sleeve 13. 5. Under the action of the elastic force, the pressure roller 14 is pushed downward and its lower end contacts the upper surface of the base 1. At this time, the metal strip 17 is located between the forming mold 2 and the pressure roller 14. Then, during the rotation of the pressure roller 14, the metal strip 17 can be bent by 90°. After the metal strip 17 is bent by 90°, the pressure roller 14 stops moving so that the bent metal strip 17 can stick to the side of the forming mold 2. Then, the remaining two reduction motors 11 are started. The speed reducer motors 11 rotate counterclockwise and clockwise respectively. When the lower ends of the pressure rollers 14 on the two speed reducer motors 11 contact the upper surface of the base 1, the metal strip 17 is located between the pressure rollers 14 and the forming mold 2. Then, through the rotation of the pressure rollers 14, the metal strip 17 continues to bend by 90°, thereby realizing the bending and forming of the trolley case frame. After the trolley case frame is bent and formed, all four speed reducer motors 11 start to operate, and the output ends of the speed reducer motors 11 continue to rotate in the previous direction. During the rotation, the pressure roller 14 is driven to rotate. Since the lower surface of the pressure roller 14 is inclined, when the pressure roller 14 moves to one side of the forming mold 2, the forming mold 2 will cause the pressure roller 14 to move upward and compress the compression spring 15 in the sleeve 13. When the pressure roller 14 moves back from the base 1 to the guide plate 16, the four reduction motors 11 stop operating. Then, by rotating the cam 8 through the handle 9, the pressure block 4 is made to release the metal strip 17. At this time, the bent metal strip 17 can be removed from the forming mold 2.

[0021] The start-stop and related actions of the four geared motors 11 are all controlled by the PLC controller. The staff only need to be responsible for feeding, pressing and unloading the metal strips 17. The remaining actions are all controlled by the PLC controller.

[0022] Furthermore, a rubber layer is provided on the outer surface of the cam 8 to facilitate the rotation of the cam 8.

[0023] Furthermore, the forming mold 2 has a long side and a short side, and the pressure block 4 is located in the middle of the long side of the forming mold 2. The length of the pressure block 4 is not less than one-third of the length of the long side of the forming mold 2, so as to avoid the situation where the two ends of the metal strip 17 warp outward when the length of the pressure block 4 acting on the metal strip 17 is too short.

[0024] Furthermore, a rubber layer is provided on the inner side of the pressure block 4 to further reduce the outward warping of the metal strip 17 when it is squeezed by the pressure block 4.

[0025] Furthermore, the height of the forming mold 2 is higher than the height of the metal strip 17 surrounding the outer surface of the forming mold 2, which facilitates the smooth movement of the pressure roller 14 from the guide plate 16 to the base 1.

[0026] Before the metal strip 17 is bent 90° by the rotating pressure roller 14, the resistance exerted by the metal strip 17 on the pressure roller 14 will not cause the compression spring 15 in the sleeve to be compressed too much. That is, the downward thrust of the pressure spring 15 on the pressure roller 14 enables the pressure roller 14 to bend the metal strip 17 by 90°. The upper end of the inclined surface of the pressure roller 14 is higher than the lowest point of the forming mold and the guide plate, so that the rotating pressure roller 14 can move onto the guide plate 16.

[0027] The pressure roller 14, the forming mold 2, and the guide plate 16 are all made of steel.
