Description

Technical Field

[0001] The utility model relates to a composite bending machine. Background Art

The material sheet needs to be moved once during the process, which will make the production efficiency low and the cost of using two equipments is high. Therefore, a composite bending machine is proposed to address the above problems. Utility Model Content

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0022] The utility model will be further described below in conjunction with the accompanying drawings.

[0023] like Figure 1-5 As shown, a compound bending machine includes a flipping assembly, a fixing assembly, a rolling assembly and a rolling moving assembly; the material sheet is arranged on the flipping assembly, the fixing assembly is arranged on the flipping assembly, and is used to fix the material sheet; the rolling assembly is arranged on the flipping assembly, and is used to roll the material sheet; the rolling moving assembly is connected to the rolling assembly, so that the rolling assembly can move and roll the material sheet.

[0024] Specifically, the material sheet is placed on the flipping assembly, fixed with a fixing assembly, and then driven by the rolling moving assembly to move the rolling assembly to roll the material sheet. At this time, the first step of rolling the material sheet is completed; then the flipping assembly drives the material sheet to flip and bend, completing the second step of operation. The above two steps complete the rolling and bending of the material sheet. Through the above structure, the operation that originally required two machines to complete can be completed by one machine of this structure, and the structural principle is simple, which saves the equipment manufacturing cost, improves the equipment compounding and improves the grade of the equipment, and also improves the production efficiency.

[0025] Specifically, the flip assembly includes a flip forming die 4, which is connected to the output end of the bending cylinder 5 for flipping the flip forming die 4; the material sheet is placed on the flip forming die 4. The output end of the bending cylinder 5 is rotatably connected to the flip forming die 4. The material sheet is transported to the flip forming die 4 through a conveyor chain.

[0026] Specifically, the fixed component includes a pressing knife 3 and a pressing knife cylinder 6 , the output end of the pressing knife cylinder 6 is connected to the pressing knife 3 , and the pressing knife 3 is arranged above the flip molding die 4 .

[0027] Specifically, the rolling assembly includes a roller cylinder 1 and a rolling wheel 2. The rolling wheel 2 is connected to the output end of the roller cylinder 1. The rolling wheel 2 is arranged above the flip forming die 4 and is used for roller forming of the material plate.

[0028] Specifically, the rolling moving assembly includes a main driving synchronous pulley 8 and a passive synchronous pulley 7, a synchronous belt is connected between the main driving synchronous pulley 8 and the passive synchronous pulley 7, and the pressure roller cylinder 1 is connected to the synchronous belt for rolling the material sheet. The main driving synchronous pulley 8 is driven by a motor reducer.

[0029] Specifically, after the sheet material is transported into the workstation and reaches the designated position, the knife pressing cylinder 6 drives the knife pressing cylinder 3 to press the sheet material downward to ensure that the sheet material remains in the same position in the subsequent actions. After pressing the sheet material, the roller cylinder 1 drives the roller wheel 2 to press down and fit the flip forming die 4, and the roller wheel 2 and the flip forming die 4 form a forming die shape, such as Figure 4 As shown,

[0030] After the pressing action is completed, the roller wheel 2 starts the rolling action under the action of the main driving synchronous pulley 8 and the passive synchronous pulley 7. After the rolling action is completed, the roller cylinder 1 drives the roller wheel 2 to rise. Then the bending cylinder 5 drives the flip forming die 5 to complete the 90-degree flip action to bend the material plate. Figure 5 As shown, the sheet metal modeling is now completed.
