Description

Technical Field

[0001] The invention relates to a pipe threading and bending structure, in particular to an automatic pipe threading and bending machine. Background Art

[0002] The automatic tube bending machine is an automated equipment specially used for processing new energy battery steel strips. When assembling batteries in battery modules, rectangular hoop straps are mostly used as binding fixing materials. The material of such rectangular hoop straps is steel strip. In the processing of steel strips, it is generally necessary to first bend the steel strip into a U-shaped semi-finished product, and then sleeve the heat shrink tube and bend the short side to form a rectangular hoop finished product.

[0003] However, in the prior art, the production process of rectangular hoop generally requires more manual participation, that is, manually holding the semi-finished steel strip to sleeve the heat shrink tube and bend the short side, which is time-consuming and labor-intensive. In order to improve the processing efficiency, the prior art also has a patented technology such as a U-shaped steel strip bending machine for rectangular hoop (Announcement No. CN117655171A). However, although this patented technology has a certain degree of automation and improves the production efficiency to a certain extent, it does not involve the automated operation of sleeve connection of heat shrink tube. Summary of the invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide an automatic tube threading and bending machine, which can realize automatic tube threading for U-shaped steel strips, and directly perform end bending and automatic unloading after tube threading, and the equipment structure also has good adjustable adaptability.

[0005] The present invention provides the following technical solutions:

[0006] An automatic tube threading and bending machine comprises a guide feeding module, a pusher module, a heat shrink tube shifting module, a tray module, a bending module and a feeder module, wherein the guide feeding module is provided with two groups with adjustable spacing, the two sides of the U-shaped steel belt are placed on the two groups of guide feeding modules, and the pusher module located between the two groups of guide feeding modules is used to push the material and thread the tube, and the heat shrink tube shifting module is also provided with two groups with adjustable spacing;

[0007] When the feeding head end of the heat shrinkable tube shifting module slides to be aligned with the tray module, it is used to receive the heat shrinkable tube discharged from the tray module. After the tray module cuts and separates the heat shrinkable tube unwound into the heat shrinkable tube shifting module, the heat shrinkable tube shifting module slides to be aligned with the guide feeding module on the corresponding side, and the heat shrinkable tube is adsorbed and opened by the port close to one end of the guide feeding module. The pushing module is used to push the U-shaped steel strip into the opened heat shrinkable tubes in the two groups of heat shrinkable tube shifting modules. A group of bending modules is also arranged at the discharge tail end of each group of heat shrinkable tube shifting modules. The bending module is used to bend the end of the steel strip after passing through the tube to form a U-shaped steel strip. The unloading module is located on one side of the heat shrinkable tube shifting module, and is used to clamp the U-shaped steel strip to separate from the guide feeding module, the heat shrinkable tube shifting module and the bending module.

[0008] The U-shaped steel strip can be first loaded onto the guide loading module, and the material tray module is used to unwind the heat shrinkable tube so that it enters the heat shrinkable tube shifting module, and the heat shrinkable tube entering the heat shrinkable tube shifting module is cut and separated. At this time, the heat shrinkable tube shifting module can drive the heat shrinkable tube to move toward each other until it is aligned with the two sets of guide loading modules, that is, the two sets of side edges of the U-shaped steel strip are aligned with the heat shrinkable tube. Then, in order to ensure the reliability of tube penetration, the heat shrinkable tube shifting module absorbs and opens the port at one end of the heat shrinkable tube, and the pushing module pushes the U-shaped steel strip again to make its two sets of side edges penetrate into the two sets of heat shrinkable tubes. After the tube penetration is completed, the bending module bends the end of the steel strip after the tube penetration to form a mouth-shaped steel strip, and the unloading module clamps the formed steel strip to separate from the guide loading module, the heat shrinkable tube shifting module and the bending module to wait for the next round of tube penetration and bending cycle.

At the same time, since the two sets of guide feeding modules and the two sets of heat shrink tube shifting modules are both set with adjustable spacing, the equipment structure can have better adjustable adaptability.

After width adjustment, the two side edges of the U-shaped steel belt can be placed on the two groups of horizontal support plates, and the two groups of feeding baffles The plate can be limited to both sides of the U-shaped steel belt; and the material tray module is fixed on the feeding mounting plate on the corresponding side. So far, in order to adapt to U-shaped steel belts of different sizes and models, when the spacing of the guide feeding module is adjusted, the position of the material tray module will also be adjusted accordingly. Therefore, after determining the corresponding positions of the heat shrinkable tube shifting module and the material tray module, for U-shaped steel belts of different sizes and models, the moving distance of the heat shrinkable tube shifting module moving toward each other and docking with the guide feeding module is the same, that is, the reciprocating distance of the heat shrinkable tube shifting module between the guide feeding module and the material tray module is always the same.

[0057] The working principle of the present invention is: in actual operation, the U-shaped steel belt 7 can be first loaded onto the guide loading module 1, and the material tray module 4 is used to unwind the heat shrink tube so that it enters the heat shrink tube shifting module 3, and the heat shrink tube entering the heat shrink tube shifting module 3 is cut and separated. At this time, the heat shrink tube shifting module 3 can drive the heat shrink tube to move toward each other until it is aligned with the two groups of guide loading modules 1, that is, the two groups of side edges of the U-shaped steel belt 7 are aligned with the heat shrink tube. Then, in order to ensure the reliability of tube penetration, after the heat shrink tube shifting module 3 adsorbs and opens the port at one end of the heat shrink tube, the pushing module 2 pushes the U-shaped steel belt 7 again to make its two groups of side edges penetrate into the two In the group of heat shrinkable tubes, after the tube is inserted, the bending module 5 bends the end of the steel strip after the tube is inserted to form a U-shaped steel strip, and the unloading module 6 then clamps the formed steel strip to separate it from the guide feeding module 1, the heat shrink tube shifting module 3 and the bending module 5 to wait for the next round of tube insertion and bending cycle; at this point, the operation of automatically inserting the heat shrink tube and bending it into a U-shaped steel strip after a group of U-shaped steel strips 7 are loaded can be completed, and after the tube is inserted, the unloading module 6 is directly used for automatic unloading. At the same time, since the two groups of guide feeding modules 1 and the two groups of heat shrink tube shifting modules 3 are all set with adjustable spacing, the equipment structure can have better adjustable adaptability.
