Description

Technical Field

[0001] This utility model relates to the technical field of keyboard chassis bending mechanism, and in particular to a keyboard chassis bending mechanism with a demolding mechanism. Background Technology

[0002] The keyboard chassis usually refers to the bottom support plate of the keyboard. It supports all the components on the keyboard. The material, design and manufacturing process of the chassis directly affect the feel of the keyboard. Some high-end keyboards use metal plates for their chassis. Before being put into use, the metal plates are bent at the edges using a bending mechanism to form an edge shape. This mechanism uses a stamping die to stamp the plate and make it bend.

[0003] In most existing bending mechanisms, when bending a keyboard chassis, the workpiece is first placed on a mold, and a pressure plate presses the workpiece into the mold. After the stamping is completed, the workpiece will be embedded in the mold. At this time, the worker needs to manually remove the workpiece. Manual removal of the workpiece is slow, and long-term stamping will damage the mold. Therefore, those skilled in the art have provided a keyboard chassis bending mechanism with a demolding mechanism to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a keyboard chassis bending mechanism with a demolding mechanism. The placement slot makes it more convenient to initially place the workpiece, eliminating the need for slow placement of the workpiece. The workpiece is pushed by the top column above the push plate, making it easier to pick up and improving the working efficiency of chassis bending.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a keyboard chassis bending mechanism with a demolding mechanism, comprising two side plates, a mold, a top plate, three demolding electric telescopic rods and four damping springs. The upper end face of the mold is provided with a placement groove, the bottom surface of the placement groove is provided with a bending groove, the bottom surface of the bending groove is provided with a lifting groove, a push plate is slidably arranged on the inner wall of the lifting groove, three top columns are evenly fixed on the upper end face of the push plate, and a bending electric telescopic rod is fixedly arranged at the middle position of the upper end face of the top plate.

[0006] A pressure plate is fixedly installed at the output end of the electric telescopic rod for bending. Limiting rods are fixedly installed on the front and rear sides of the upper surface of the pressure plate. A slider is fixedly installed in the middle of the inner wall of the opposite side of the two side plates. A sliding groove is opened in the middle of the end face of both sides of the mold.

[0007] Furthermore, the two inner bottom surfaces of the two side plates are provided with lower grooves at the front and rear sides, and the four damping springs are respectively arranged on the inner bottom surfaces of the four lower grooves.

[0008] Furthermore, upper grooves are provided on the front and rear sides of the inner top surface of both sides of the mold, and the four damping springs are respectively arranged on the inner top surface of the four upper grooves.

[0009] Furthermore, anti-slip pads are fixedly provided on the front and rear sides of the lower end face of the side plate, and the two sliders are respectively slidably disposed on the inner walls of the two grooves.

[0010] Furthermore, vertical blocks are fixedly installed on both sides of the bottom and top surfaces of the lifting groove, and square grooves are opened on both sides of the upper surface of the push plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes a keyboard chassis bending mechanism with a demolding mechanism. The workpiece is placed in the inner wall of the placement groove. The restriction of the placement groove makes it easier to initially place the workpiece, eliminating the need to slowly position the workpiece. The bending electric telescopic rod presses the workpiece through the pressure plate. Four limit rods are set above the pressure plate. These limit rods are slidably set on the inner wall of the top plate. The limitation of the limit rods makes the pressure plate more stable when pressing down.

[0016] 2. The keyboard chassis bending mechanism proposed in this utility model has a demolding mechanism. The mold and the side plate are supported by a damping spring. When bending, the mold will slide downward. The damping spring buffers the excessive impact force of the pressure plate, which may damage the mold. Moreover, when the mold moves, the slider slides inside the slide groove, which makes the mold more stable.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 5 An embodiment of this utility model is provided: a keyboard chassis bending mechanism with a demolding mechanism, including two side plates 1, a mold 3, a top plate 10, three demolding electric telescopic rods 17 and four damping springs 20. The upper end face of the mold 3 is provided with a placement groove 5, the bottom surface of the placement groove 5 is provided with a bending groove 4, the bottom surface of the bending groove 4 is provided with a lifting groove 15, a push plate 19 is slidably arranged on the inner wall of the lifting groove 15, three top columns 2 are evenly fixed on the upper end face of the push plate 19, and a bending electric telescopic rod 8 is fixedly arranged at the middle position of the upper end face of the top plate 10.

[0026] A pressure plate 12 is fixedly installed at the output end of the electric telescopic rod 8. Limiting rods 9 are fixedly installed on the front and rear sides of the upper surface of the pressure plate 12. A slider 13 is fixedly installed in the middle of the inner wall of the opposite side of the two side plates 1. A sliding groove 6 is opened in the middle of the end face of both sides of the mold 3.

[0027] Lower grooves 22 are provided on the front and rear sides of the inner bottom surface of the two side plates 1. Four damping springs 20 are respectively installed on the inner bottom surface of the four lower grooves 22. Upper grooves 21 are provided on the front and rear sides of the inner top surface of both sides of the mold 3. Four damping springs 20 are respectively installed on the inner top surface of the four upper grooves 21. Anti-slip pads 14 are fixedly installed on the front and rear sides of the lower end surface of the side plates 1. Two sliders 13 are respectively slidably installed on the inner walls of the two slide grooves 6.

[0028] Vertical blocks 18 are fixedly installed on both sides of the bottom and top surfaces of the lifting groove 15. Square grooves 23 are opened on both sides of the upper surface of the push plate 19. The two square grooves 23 are slidably installed on the outer surfaces of the two vertical blocks 18. Three bottom grooves 16 are evenly opened on the bottom surface of the lifting groove 15. Three demolding electric telescopic rods 17 are fixedly installed on the bottom surfaces of the three bottom grooves 16. The output ends of the three demolding electric telescopic rods 17 are fixedly installed on the lower surface of the push plate 19. Support rods 11 are fixedly installed on the front and rear sides of the upper surfaces of the two side plates 1. The top plate 10 is fixedly installed on the upper surfaces of the four support rods 11. Limiting blocks 7 are fixedly installed on the upper surfaces of the four limiting rods 9. The four limiting rods 9 pass through the top plate 10.

[0029] Specifically, when bending and edging the edge of the keyboard chassis, the workpiece is placed inside the placement groove 5. The placement groove 5 makes it easier to initially place the workpiece. The electric bending telescopic rod 8 is activated to push the pressure plate 12. The pressure plate 12 is smaller than the bending groove 4. The pressure plate 12 presses into the placement groove 5 and presses the workpiece tightly, causing the workpiece to be pressed into the inner wall of the bending groove 4. At this time, the edge of the workpiece will be raised to form the keyboard chassis. Moreover, four limiting rods 9 are set above the pressure plate 12. These limiting rods 9 are slidably set on the inner wall of the top plate 10. The limiting rods 9 make the pressure plate 12 more stable when pressing down. A limiting block 7 is set above the limiting rods 9. The limiting block 7 can limit the height of the pressure plate 12 when pressing down to avoid excessive pressure. During the pressing, the mold 3 will slide downward. The mold 3 is supported by a damping spring 20. The damping spring 20 buffers the impact of the pressure plate 12 to prevent damage to the mold 3. When the mold 3 moves up and down, the slider 13 slides inside the slide groove 6, making the mold 3 more stable. After bending, the electric bending telescopic rod 8 is activated to pull the pressure plate 12 and raise it. Without the pressure of the pressure plate 12, the mold 3 is pushed back by the damping spring 20. A vertical block 18 is set inside the lifting groove 15. The vertical block 18 supports the bottom surface of the bending groove 4, making the bending groove 4 more stable and preventing it from being crushed. At this time, the electric demolding telescopic rod 17 is activated to push the push plate 19. The upward-moving push plate 19 pushes the workpiece through the top column 2, allowing the workpiece to be removed from the bending groove. The workpiece can be picked up quickly, making the workpiece processing more efficient.

[0030] Working principle: When bending and edging the edge of the keyboard chassis, the workpiece is first placed in the inner wall of the placement groove 5. The bending electric telescopic rod 8 is activated to push the pressure plate 12, pressing it into the placement groove 5 to press the workpiece tightly. This forces the workpiece into the inner wall of the bending groove 4. Since the size of the bending groove 4 is smaller than that of the placement groove 5, the edge of the workpiece is squeezed and bent. During the pressing process, the mold 3 slides downward under pressure. It is buffered and supported by the damping spring 20 between it and the side plate 1. After the bending is completed, the bending electric telescopic rod 8 is activated to pull back the pressure plate 12 to make it rise. After the pressure is lost, the mold 3 is reset under the action of the damping spring 20. At this time, the demolding electric telescopic rod 17 is activated to push the push plate 19. The rising push plate 19 pushes the workpiece out of the bending groove through the top column 2, and the workpiece can be quickly removed.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
