DETAILED DESCRIPTION

[0029] Referring to Figures 1-5 The utility model relates to a kind of bending module, including first clamping part 11, for clamping plastic profile;Bending forming part 12, inside is provided with heating cavity 125, and heating cavity 125 inside is provided with multiple plastic profile placement slot for placing plastic profile;First driving device 13, with bending forming part 12 driving connection and drive bending forming part 12 rotation;Heating device, heating device is connected with the bending forming part 12, heating gas is conveyed to the heating cavity 125 formed after bending forming part 12 compression, to the plastic profile heating that is provided in heating cavity 125.

[0030] Specific technical effect is in:

[0031] Meanwhile, the structure of the bending module is reasonable, which can adapt to the bending needs of plastic profiles of different sizes and shapes. By adjusting the clamping of the first clamping part 11 plastic profile, as well as the output power and time of the heating device and other parameters, the accurate bending of different specifications of plastic profiles can be realized. The structure of the bending module is relatively simple, and the connection and transmission mode between the components are relatively direct. This makes the maintenance and maintenance work relatively easy, reduces the operation cost and maintenance cost of the equipment.

[0032] The utility model discloses a bending device, and the specific use process is: through the plastic profile is placed in first clamping part 11 and the bending forming part 12, constitute a heating cavity 125 between bending forming part 12, through the heating device of opening generates heating gas (in this embodiment, it is high pressure water vapor), high pressure water vapor enters heating cavity 125 through pipeline, heats the plastic profile in heating cavity 125, then is driven bending forming part 12 to rotate by first drive device 13, can realize the bending of plastic pull rod, and the profile is clamped by first clamping part 11 in the bending process.The plastic pull rod of this bending mode has good physical performance, and can satisfy actual use.

[0033] Therefore, the high-pressure water vapor heating mode not only has a fast heating speed but also has uniform heating. This makes it easy to control the shape and size of the plastic profile during the bending process, thereby reducing the waste rate. At the same time, since the cost of the plastic profile is generally lower than that of metal materials such as aluminum alloy, the production cost of the luggage and other products can be reduced by using the technical scheme.

[0034] Further, the first clamping part 11 includes a first fixed plate 113, a first clamping cylinder 111, and a first clamping bottom plate 114. The first clamping cylinder 111 is fixed on the first fixed plate 113, and the first clamping bottom plate 114 is fixed on the first fixed plate 113. The movable end of the first clamping cylinder 111 is connected with a first clamping moving plate 112 and drives the first clamping moving plate 112 to move towards the first clamping bottom plate 114, so that the plastic profile is clamped between the first clamping moving plate 112 and the first clamping bottom plate 114.

[0035] Since the first clamping cylinder 111 provides a stable driving force, it can ensure that the plastic profile is stably clamped. This helps to reduce errors and waste rates during the bending process. The design of the first clamping part 11 has a certain flexibility and can adapt to plastic profiles of different sizes and shapes. By adjusting the working pressure and stroke of the cylinder, the clamping requirements of different plastic profiles can be met. The structure of the first clamping part 11 is relatively simple, and the connection and transmission between the components are relatively direct. This makes maintenance and repair work relatively easy, reducing the operating cost and maintenance cost of the equipment. Stable clamping effect helps to reduce the movement and falling of the plastic profile during the bending process, thereby improving the processing efficiency of the entire bending module.

[0036] Further, the bending forming part 12 includes a second fixed plate 121, a second clamping air cylinder 122, and a first clamping bottom shell 123, wherein the second clamping air cylinder 122 is fixed on the second fixed plate 121, the first clamping bottom shell 123 is fixed on the second fixed plate 121, the movable end of the second clamping air cylinder 122 is connected with a first clamping face shell 124, and drives the first clamping face shell 124 to move towards the first clamping bottom shell 123 and make the plastic profile be clamped between the first clamping face shell 124 and the first clamping bottom shell 123, and a heating cavity 125 is formed between the first clamping face shell 124 and the first clamping bottom shell 123; and the first driving device 13 is drivingly connected with the second fixed plate 121.

[0037] When the second clamping air cylinder 122 receives the clamping instruction, the air pressure inside the cylinder changes, driving the movable end (i.e. the first clamping face shell 124) to move towards the first clamping bottom shell 123. The first clamping face shell 124 gradually approaches the first clamping bottom shell 123 under the drive of the cylinder, and the space between them decreases until the plastic profile is preliminarily positioned. At the same time, a heating cavity 125 is formed between the first clamping face shell 124 and the first clamping bottom shell 123, which can be used for heating treatment of the clamped plastic profile. After the plastic profile is heated and reaches the appropriate bending temperature, the first driving device 13 is started to drive the entire bending forming part 12 to move or rotate on the equipment, so as to bend the heated plastic profiles (it should be noted that the bending forming part 12 does not clamp the plastic profile in this process, but only bends the plastic profile along the rotating bending radius).

[0038] The bending forming part 12 provides stable driving force through the second clamping air cylinder 122, ensuring that the plastic profile is wrapped (not clamped, which would tear the plastic profile if clamped and rotated) between the first clamping face shell 124 and the first clamping bottom shell 123, avoiding movement or falling off during processing. The design of the heating cavity 125 allows the clamping part to clamp the plastic profile while also heating it, improving the flexibility and efficiency of the processing. The driving connection of the first driving device 13 and the second fixed plate 121 allows the entire bending forming part 12 to flexibly bend the heated plastic profiles. This design improves the efficiency and accuracy of bending, reducing processing time and cost.

[0039] The bending forming part 12 has a compact structure, and the connection and transmission mode between the components are direct, so that the overall volume of the equipment is small, facilitating installation and arrangement. The simplicity of the structure also makes maintenance and repair work relatively easy, reducing the operating and maintenance costs of the equipment.

The side of the first clamping surface shell 124 close to the mounting clamping positions 1241 is also provided with a plurality of guide wheels 126, and the guide wheels 126 are provided with guide groove positions aligned with the mounting clamping positions 1241. The first clamping surface shell 124 is closed on the first clamping bottom shell 123, and the corresponding mounting clamping positions 1241 and the surface of the first clamping bottom shell 123 form plastic profile placing grooves.

[0041] The side of the first clamping surface shell 124 is provided with a plurality of mounting clamping positions 1241, which are used to separate the plastic profiles in detail. The other side is provided with a mounting gap, which is convenient for placing the plastic profiles. The side of the first clamping surface shell 124 close to the mounting clamping positions 1241 is also provided with a plurality of guide wheels 126, and the guide wheels 126 are provided with guide groove positions aligned with the mounting clamping positions 1241. The cooperation of the plurality of mounting clamping positions 1241 and the guide wheels 126 enables the plastic profiles to be accurately separated and positioned while being wrapped. The design of the guide wheels 126 ensures the smoothness of the plastic profiles during the placing and taking out process, and the alignment of the guide groove positions and the mounting clamping positions 1241 also ensures the accuracy of the positioning of the plastic profiles. The first driving device 13 is drivingly connected with the second fixed plate 121 to drive the entire bending forming part 12 to move or rotate on the equipment, so as to bend the plurality of plastic profiles which have been heated and positioned.

[0042] Further, the side of the first clamping bottom shell 123 close to the mounting gap is also provided with a plurality of guide wheels 126, and the guide wheels 126 are provided with a plurality of guide groove positions. The side of the first clamping bottom shell 123 close to the mounting gap is also provided with a plurality of guide wheels 126, and the guide wheels 126 are also provided with a plurality of guide groove positions. These guide wheels 126 and guide groove positions are to ensure the smoothness of the plastic profiles during the placing and taking out process, and the stability during the clamping process.

[0043] Further, the first clamping bottom shell 123 is also provided with a plurality of guide rods 127, and the other end of the guide rod 127 is movably inserted through the first clamping surface shell 124. The first clamping bottom shell 123 is also provided with a plurality of guide rods 127, and the other end of the guide rod 127 is movably inserted through the first clamping surface shell 124. The guide rod 127 functions to ensure that the first clamping surface shell 124 can maintain stable linear motion when moving under the driving of the air cylinder, avoiding deflection or shaking. The movable connection between the guide rod 127 and the first clamping surface shell 124 allows the first clamping surface shell 124 to move as necessary when wrapping and releasing the plastic profiles, while maintaining its positional accuracy and stability. At the same time, the first clamping bottom shell 123 is also provided with a pipeline corresponding to the heating device, and the first clamping bottom shell 123 is provided with a plurality of air vents (for outputting hot air) inside.

[0044] Further, the first driving device 13 comprises a first servo motor 131, a worm 133, a first power shaft 134, and a driving fixed plate 132, wherein the first servo motor 131 is fixed on the driving fixed plate 132, the output shaft of the first servo motor 131 is drivingly connected with the worm 133, the worm 133 is connected with the first power shaft 134, the first power shaft 134 is drivingly connected with the second fixed plate 121, and drives the second fixed plate 121 to rotate; meanwhile, the first fixed plate 113 is fixedly connected with the driving fixed plate 132 through a third fixed plate 135.

[0045] When it is needed to wrap the plastic profile, the second clamping cylinder 122 drives the first clamping face shell 124 to move towards the first clamping bottom shell 123, so as to clamp the plastic profile therebetween. Meanwhile, the heating cavity 125 performs heating treatment on the plastic profile. When it is needed to bend the plastic profile, the first servo motor 131 is started, and the second fixed plate 121 and the bending forming part 12 thereon are driven to rotate as a whole through the worm 133 and the first power shaft 134, so as to realize bending of the plastic profile.

[0046] The application also provides a luggage frame bending machine, which comprises four bending modules, a first adjusting device 21, a second adjusting device 22, and a third adjusting device 23, wherein the four bending modules comprise a first bending module 101, a second bending module 102, a third bending module 103, and a fourth bending module 104, the first adjusting device 21 comprises two adjusting movable ends which can approach or move away from each other, wherein the two adjusting movable ends are respectively fixedly connected with the driving fixed plates 132 of the first bending module 101 and the second bending module 102, and make the first bending module 101 and the second bending module 102 approach or move away from each other, and the two adjusting movable ends of the second adjusting device 22 are respectively connected with the second fixed plates 121 of the first bending module 101 and the driving fixed plates 132 of the third bending module 103; the two adjusting movable ends of the third adjusting device 23 are respectively connected with the second fixed plates 121 of the second bending module 102 and the driving fixed plates 132 of the fourth bending module 104.

[0047] In the bending process, the four bending modules respectively clamp different parts of the luggage frame. The plastic profile is heated by the heating cavity 125 to reach a temperature suitable for bending. Subsequently, the driving devices of the bending modules are started, so as to drive the clamping face shell and the bottom shell to move relatively, and realize bending of the plastic profile.

[0048] Before bending, the relative positions between the four bending modules are adjusted by the first, second and third adjusting devices 23 according to the size of the luggage frame and the bending requirements. The first adjusting device 21 can make the first bending module 101 and the second bending module 102 approach or move away from each other to adapt to luggage frames of different widths. The second adjusting device 22 and the third adjusting device 23 adjust the relative positions between the first bending module 101 and the third bending module 103, and between the second bending module 102 and the fourth bending module 104, respectively, to adapt to the length and bending shape of the luggage frame.

[0049] After the bending process is completed, the clamping cylinders of each bending module are released, and the clamping of the luggage frame is released. The first, second and third adjusting devices 23 make the adjacent bending modules approach each other.

[0050] The first adjusting device 21 makes the first bending module 101 and the second bending module 102 approach each other. The second adjusting device 22 reduces the gap between the first bending module 101 and the third bending module 103.

[0052] Further, the first adjusting device 21 includes a first adjusting motor 212, a bidirectional screw 211, and sliding nuts movably sleeved on both ends of the bidirectional screw 211. The first adjusting motor 212 drives the bidirectional screw 211 to rotate and causes the two sliding nuts to approach or move away from each other along the direction of the bidirectional screw 211, and the two sliding nuts constitute an adjusting movable end. When the first adjusting motor 212 is started, it drives the bidirectional screw 211 to rotate. Due to the opposite directions of the threads of the bidirectional screw 211, the two sliding nuts will move to the middle or the two ends at the same time under the rotating action of the bidirectional screw 211, realizing the approach or movement away from each other. The two sliding nuts constitute an adjusting movable end and are fixedly connected with the drive fixed plates 132 of the first bending module 101 and the second bending module 102, respectively. By adjusting the rotating direction and speed of the first adjusting motor 212, the relative position between the first bending module 101 and the second bending module 102 can be accurately controlled.

[0054] 1. Preparation stage

[0055] According to the size and bending requirements of the luggage frame, first adjust the first adjusting device 21, the second adjusting device 22 and the third adjusting device 23. These adjusting devices respectively control the relative positions between the four bending modules (the first bending module 101, the second bending module 102, the third bending module 103, the fourth bending module 104).

[0056] Specifically, the first adjusting device 21 drives the bidirectional screw 211 to rotate through the first adjusting motor 212 inside it, so that the two sliding nuts move closer to or away from each other along the direction of the bidirectional screw 211, thereby adjusting the distance between the first bending module 101 and the second bending module 102. Similarly, the second adjusting device 22 and the third adjusting device 23 also adjust the distances between other bending modules respectively. Place the luggage frame to be bent in the appropriate position of the bending machine, and ensure that each bending module can accurately clamp different parts of the frame.

[0057] 2. Clamping and heating stage

[0058] The clamping cylinders of each bending module are started to tightly clamp the luggage frame through the first clamping part 11.

The heating device starts to work, and high-pressure water vapor is delivered to the heating cavity 125 to heat the clamped frame part to a temperature suitable for bending.

[0059] 3. Bending stage

[0060] When the plastic profile is heated to a suitable temperature, the driving device (such as the first servo motor 131 through the worm 133, the first power shaft 134, the worm gear, etc.) of each bending module is started to drive the bending forming part 12 to rotate, realizing the bending of the plastic profile.

[0061] 4. Loosen and take out stage

[0062] After the bending process is completed, the clamping cylinders of each bending module are released to loosen the clamping of the luggage frame. Adjust again through the first adjusting device 21, the second adjusting device 22 and the third adjusting device 23, so that the adjacent bending modules move closer to each other. In this way, a small gap is formed between the bent luggage frame and the corresponding bending module, which is convenient for the operator or automatic equipment to take out the plastic profile.

[0063] The beneficial effects of the overall scheme are

[0064] 1. Improve production efficiency

[0065] By integrating four independent bending modules, the device can simultaneously process multiple parts of the luggage frame, greatly improving production efficiency. The structure of the bending module is reasonable and can adapt to the bending needs of plastic profiles of different sizes and shapes, reducing the time for changing molds and adjusting the equipment.

[0066] 2. Reduce production cost

[0067] Using plastic profiles as the material for the luggage frame, the cost is lower compared to traditional aluminum alloy materials. The device structure is compact, and the connection and transmission between components are direct, reducing the manufacturing and maintenance costs of the equipment.

[0068] 3. Improve processing accuracy

[0069] The bending module uses high-pressure steam heating, which has fast and uniform heating speed, making it easy to control the shape and size of the plastic profile during the bending process, reducing the scrap rate. The adjustment device uses a motor-driven bidirectional screw 211, which realizes precise control of the position of the bending module, further improving the processing accuracy.

[0070] 4. Easy to operate

[0071] The device design is reasonable and easy to operate, reducing the skill requirements for the operator. After the bending process is completed, the adjacent bending modules can automatically approach, making it easy to take out the plastic profile and reducing manual intervention.
