DETAILED DESCRIPTION

[0017] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific implementation manner of the utility model is described in detail below with reference to the drawings.

[0018] Secondly, the utility model is described in detail in combination with the schematic view, and in the detailed description of the utility model implementation manner, for the convenience of description, the sectional view of the device structure will be partially enlarged without the general proportion, and the schematic view is only an example, which should not limit the scope of protection of the utility model herein. In addition, the three-dimensional spatial dimensions of length, width and depth should be included in the actual manufacture.

[0019] In order to make the purpose, technical scheme and advantages of the utility model more clear, the implementation manner of the utility model will be described in further detail below in combination with the drawings.

[0020] Figs. 1-3It shows that the whole structure schematic diagram of the right angle bending mechanism for spring wire of the utility model, please refer to Figs. 1-3 The right angle bending mechanism for spring wire of the embodiment comprises an installation back plate 100, a clamping assembly 200 is arranged on one side of the installation back plate 100, the clamping assembly 200 is located at the right side close to the wire outlet, a positioning wheel 300 is arranged on the right side of the clamping assembly 200 and is longitudinally rotatably installed on the installation back plate 100, an angle bending wheel 400 is matched above the positioning wheel 300, an arc-shaped electric sliding rail 500 coaxial with the positioning wheel 300 is arranged on the plate surface of the installation back plate 100, a sliding block 510 is slidably arranged in the arc-shaped electric sliding rail 500, a connecting rod 520 extending to the position of the angle bending wheel 400 is fixed to the outer end of the sliding block 510, and the angle bending wheel 400 is longitudinally rotatably installed on the end part of the connecting rod 520.

[0021] The clamping assembly 200 comprises a fixed clamp block 210 fixed on the mounting back plate 100, a movable clamp block 220 vertically slidingly mounted on the mounting back plate 100 and located directly above the fixed clamp block 210, a positioning block 230 located directly above the movable clamp block 220 and fixed on the mounting back plate 100, an electric push rod 240 vertically fixedly mounted at the center of the positioning block 230 and used to drive the movable clamp block 220 to move up and down, and rubber pads 250 respectively arranged on the opposite sides of the fixed clamp block 210 and the movable clamp block 220. It can be understood that when the straight section of the spring wire passes above the fixed clamp block 210 and no longer advances, the electric push rod 240 will push the movable clamp block 220 to quickly descend and form a clamping on the wire with the fixed clamp block 210, and the rubber pads 250 can prevent the wire from being damaged. The center of the positioning wheel 300 and the corner wheel 400 also has a ring groove, and the groove spacing between the positioning wheel 300 and the corner wheel 400 is greater than the diameter of the spring wire. The ring groove can prevent the wire from sliding sideways during bending and has a positioning effect. The shaft of the positioning wheel 300 is fixedly connected to a rotating shaft one 310 rotatably mounted on the mounting back plate 100, and the shaft of the corner wheel 400 is fixedly connected to a rotating shaft two 410 rotatably mounted on the connecting rod 520. Rotational mounting allows the positioning wheel 300 and the corner wheel 400 to form a movable contact with the wire during bending, preventing scratches on the wire outer sheath. It should be noted that the mounting back plate 100 in this embodiment can be fixedly mounted on the device or movably mounted on the device. If it is movably mounted, the mounting back plate 100 can be moved to the wire outlet position of the device when bending is required, and this is not limited. The mounting back plate 100 also has a limiting block 600 located to the right of the positioning wheel 300, and a stop button 610 is arranged on the upper part of the limiting block 600. Specifically, in this embodiment, when the spring wire needs to be bent at a right angle during use, the straight section of the spring wire delivered from the wire outlet will pass through the clamping assembly 200 and continue to pass through the middle part of the positioning wheel 300 and the corner wheel 400. After stopping advancing, the control unit will immediately start the clamping assembly 200 and press the root of the wire to be stable, and then the corner wheel 400 will be radially wound along the positioning wheel 300 under the cooperation of the arc-shaped electric sliding rail 500, the sliding block 510, etc., and the wire extending out will be bent until the connecting rod 520 touches the stop button 610, and the sliding block 510 will automatically stop. Thus, the right-angle bending of the spring wire is completed, and the next bending operation can be continued. In summary, the right-angle bending mechanism for the spring wire has the characteristics of reasonable design, simple structure and easy maintenance, and is suitable for popularization and application.

[0022] As preferred, further, the installation backboard 100 is further provided with a discharging sensing component 700, and the discharging sensing component 700 is arranged at a position below the middle of the right side of the clamping assembly 200 and the positioning wheel 300. It can be understood that the discharging sensing component 700 here can be an infrared sensor, an ultrasonic sensor, etc., and only when the discharging sensing component 700 senses the wire body of the spring wire, the control unit will determine that the bending operation and running are needed, and when the wire body is not sensed, the whole bending mechanism is in a stationary state.

[0023] In summary, the right-angle bending mechanism for spring wire in the embodiment, when the spring wire needs to be right-angle bent, the straight line segment of the spring wire delivered from the wire outlet will pass through the clamping assembly 200 and continue to pass through the middle part of the positioning wheel 300 and the angle wheel 400, after stopping advancing, the control unit will start the clamping assembly 200 and press the wire root tightly and stably, then the angle wheel 400 will be radially revolved along the positioning wheel 300 under the cooperation of the arc-shaped electric sliding rail 500, the sliding block 510, etc., and the wire extending out will be bent, until the sliding block 510 will be automatically stopped when the connecting rod 520 touches the stopping button 610, thus the right-angle bending of the spring wire is completed, and the return can continue the next round of bending operation.

[0024] Although the utility model has been described above with reference to the embodiments, various improvements can be made and equivalent parts can be replaced without departing from the scope of the utility model. In particular, as long as there is no structural conflict, each feature in the disclosed embodiments of the utility model can be combined with each other in any way, and the combinations are not described in this specification due to the consideration of omitting the length and saving resources. Therefore, the utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
