Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a bending machine for bending and forming glass spacer frames. Background Technology

[0002] For bending machines used in glass spacer frame bending, bending accuracy, operational stability, and operational flexibility are the core performance indicators. As key equipment for ensuring the quality of spacer frame forming, the bending angle control, pressure adjustment, and smooth operation of such bending machines directly affect the splicing accuracy and performance of the spacer frames. Especially for insulated glass spacer frames with stringent requirements, ensuring that the bending machine maintains a stable processing state during continuous operation, reducing errors, and avoiding deformation has become a core design and development issue. Through technological optimization, the bending machine can not only effectively improve the forming consistency of the spacer frames but also enhance the fatigue resistance of the equipment, reduce the number of downtime adjustments and maintenance costs, and ensure efficient production. In addition, the convenient parameter adjustment design takes into account the processing needs of spacer frames of different specifications, improving production efficiency while broadening the applicability of the equipment.

[0003] The bending machine mainly consists of a precision bending mechanism and a stable power transmission device. The precision bending mechanism, as the core component, employs high-rigidity bending dies and servo drive technology to precisely control the bending angle and edge length, providing accurate forming assurance for the spacer frame. The machine body is made of high-strength alloy steel, possessing excellent anti-deformation performance. Even under prolonged high-intensity operation, it maintains structural stability, preventing a decrease in processing accuracy due to machine body deformation. Combined with a closed-loop pressure feedback system and multi-stage bending program design, the bending machine maintains stable bending results even when processing profiles of different thicknesses, effectively ensuring the dimensional accuracy and forming quality of the spacer frame. The stable power transmission device provides continuous power support to the bending machine. Through optimized matching of the gearbox and drive shaft, the smoothness of power output is enhanced, preventing power fluctuations from affecting processing accuracy and improving the operational reliability of the equipment.

[0004] In the processing of glass spacer frames, this type of bending machine has the obvious disadvantage of not being able to fix various types of frames. Its bending mold and positioning components have limited compatibility and can only match frame profiles of specific specifications. When processing spacer frames with different cross-sectional dimensions and shapes, it is necessary to frequently change the mold and positioning components, which not only prolongs the preparation time but also reduces the processing efficiency due to repeated adjustments. This limitation makes it difficult for the equipment to cope with diverse production needs and increases the equipment investment and management costs of enterprises. Therefore, a bending machine for bending and forming glass spacer frames is proposed to solve the above problems. Utility Model Content

[0011] As a further description of the above technical solution:

[0012] The sliding assembly includes a connecting column one, the top end of which is fixedly connected to the bottom end of the fixing block one, and two support plates two are fixedly connected to the outside of the sliding assembly.

A third connecting column is fixedly connected to the outside of the second rotating shaft. A clamp is fixedly connected to the top of the third connecting column. A fixed support is rotatably connected to the outside of the second rotating shaft.

[0017] As a further description of the above technical solution:

[0018] The bottom end of the support plate is fixedly connected to a plurality of support columns, and one end of the connecting plate is fixedly connected to the bottom end of the gripper.

[0019] As a further description of the above technical solution:

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, when using this device, the spacer frame must first be inserted along the center of the clamping mechanism and the cleaning mechanism. Start motor one, which drives the rotating plate to rotate. The rotating plate drives the follower plate to move synchronously. The follower plate then drives the connecting plate one to retract inward, thereby achieving a stable clamping of the spacer frame. Then start telescopic rod one. When telescopic rod one retracts, it will drive the connecting column one to slide in the direction of the bending mechanism inside the support plate one, thereby pushing the spacer frame forward. If a second bending is required, motor one can be started in reverse to release the spacer frame, and then telescopic rod one can be started to retract backward. Since the fixed block one has a rotating shaft inside, it can prevent the clamp from driving the spacer frame backward during the retraction process. After the device is reset, the above initial operation can be repeated to complete the second bending.

[0025] 2. In this utility model, when the spacer frame passes through the cleaning mechanism, it first passes through the dust removal brush to remove the dust attached to the surface and prevent the dust from falling into the equipment and aggravating the wear of the parts. During this process, the spacer frame will press the fixing block three outward, and the fixing block three will push the connecting column two outward. The connecting column two will then press the elastic rod fixed inside the connecting tube one. The elastic deformation of the elastic rod achieves self-adjustment and can also adapt to spacer frames of different shapes and sizes, ensuring that the cleaning process is stable and efficient.
