Description

Technical Field

[0001] The utility model relates to the technical field of mechanical housing production, and particularly relates to a mechanical housing bending device. Background Art

[0002] A bending device is a machine capable of bending thin plates. Its structure mainly includes a bracket, a workbench, and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressing plate. The base is connected to the clamping plate through a hinge. The base is composed of a housing, a coil, and a cover plate. The coil is placed in the recess of the housing, and the cover plate covers the top of the recess. When in use, the coil is energized by a wire, and after energization, an attractive force is generated on the pressing plate, thereby realizing the clamping of the thin plate between the pressing plate and the base.

[0003] In the production of mechanical housings, it is necessary to bend thin plates. When bending the thin plates, as the pressing plate drops, the thin plates are prone to displacement during the bending process, which in turn causes the bending part to shift, affecting the bending and forming of the thin plates. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the above-mentioned disadvantages in the prior art, and a mechanical housing bending device is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: design a mechanical housing bending device, including a base. Support seats are arranged on both sides of the top of the base, and there is a gap between the two support seats. Grooves are opened on the relatively far sides of the two support seats;

[0006] A bearing plate is arranged above the support seats. The ends of the two bearing plates close to each other are rotatably installed in the grooves, and a telescopic mechanism is arranged below the bearing plate. The end of the telescopic mechanism is rotatably installed in a U-shaped seat. One of the U-shaped seats is fixed in the groove, and the other U-shaped seat is fixed on the bearing plate;

[0007] A strip-shaped pressing block is arranged above the position between the two support seats. The pressing block is arranged along the length direction of the gap. A lifting mechanism is installed on the top of the pressing block, and the lifting mechanism is connected to the base through an L-shaped frame;

[0008] Receiving grooves are opened at the bottoms on both sides of the pressing block, and pressing plates are arranged in the receiving grooves. One end of the pressing plate is rotatably connected to the bottom of the receiving groove through a connecting shaft, and the pressing plate corresponds to the bearing plate. A torsion spring is sleeved on the connecting shaft. One end of the torsion spring is fixed on the inner wall of the receiving groove, and the other end of the torsion spring is fixed on the pressing plate.

[0009] Preferably, the bottom cross-section of the pressing block is a regular "V" shape with a smooth lower end.

[0010] Preferably, a non-slip rubber pad is installed on the side of the pressing plate close to the bearing plate.

[0011] Preferably, a non-slip rubber pad is installed on the top surface of the bearing plate.

[0012] Preferably, a strip-shaped groove is provided on the top surface of the bearing plate along the length direction of the pressing block. A linear motor is arranged in the strip-shaped groove. The slide rail of the linear motor is installed in the strip-shaped groove, and an "L"-shaped first limiting plate is installed on the slide block of the linear motor. An "L"-shaped second limiting plate opposite to the first limiting plate is installed on the top surface of one end of the bearing plate.

[0013] Preferably, there are at least two second limiting plates which are arranged on both sides of the strip-shaped groove.

[0014] Preferably, at least one guide shaft is arranged in parallel on the side surface of the lifting mechanism. The bottom of the guide shaft is fixed on the top of the pressing block, and the other end of the guide shaft slides through the L-shaped frame.

[0015] The beneficial effects of the design scheme proposed by the present utility model in the application process are as follows:

[0016] 1. By approaching the bearing plate through the pressing block, the pressing plate can be pressed on the bearing plate, so as to tightly fix the plate placed on the bearing plate. As the pressing block continues to press down and the bearing plate turns upward, the pressing plate will continuously increase the fastening effect on the plate under the twisting of the torsion spring, while ensuring the bending and forming of the plate, reducing the probability of the plate shifting due to force.

[0017] 2. The mechanical housing bending device drives the first limiting plate to move linearly through the linear motor, and can limit the side surface of the plate according to the size of the plate, so as to prevent the plate from shaking during bending, and further improve the stability of the plate during bending.

Detailed implementation manner

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Refer to Figures 1-5 , a mechanical housing bending device, including a base 1, support bases 2 are arranged on both sides of the top of the base 1, and a gap is left between the two support bases 2 for bending.

[0026] As Figure 1 and Figure 4 shown, grooves 3 are opened on the relatively far sides of the two support bases 2, a bearing plate 4 is arranged above the support bases 2, the ends of the two bearing plates 4 close to each other are rotatably installed in the grooves 3, and a telescopic mechanism 5 is arranged below the bearing plate 4. The end of the telescopic mechanism 5 is rotatably installed in a U-shaped seat 6. One of the U-shaped seats 6 is fixed in the groove 3, and the other U-shaped seat 6 is fixed on the bearing plate 4. In the actual use process, the telescopic mechanism 5 is one of an electric push rod, a hydraulic cylinder, and a cylinder. Under the action of the telescopic mechanism 5 on the bearing plate 4, the bearing plate 4 can be driven to turn upwards in the groove 3, that is, the two bearing plates 4 are deflected in a "V" shape.

[0027] As Figure 1 and Figure 5 shown, a strip-shaped groove 7 is opened on the top surface of the bearing plate 4 along the length direction of the pressing block 11. A linear motor 8 is arranged in the strip-shaped groove 7. The slide rail of the linear motor 8 is installed in the strip-shaped groove 7, and an "L"-shaped first limit plate 9 is installed on the slider of the linear motor 8. An "L"-shaped second limit plate 10 opposite to the first limit plate 9 is installed on the top surface of one end of the bearing plate 4. When the plate is placed on the bearing plate 4, one side of the plate will be placed in the second limit plate 10, and then the first limit plate 9 will approach the other side of the plate under the operation of the linear motor 8, so as to realize the clamping and fixing of the plate.

[0028] It should be noted that, as Figure 1 and Figure 5 shown, the second limit plate 10 is at least two and is arranged on both sides of the strip-shaped groove 7 to increase the contact surface between the limit plate and the plate, thereby improving the effect of the limit plate on the plate.

[0029] As Figure 1 shown, above the position between two support seats 2, a strip-shaped pressing block 11 is provided. The pressing block 11 is arranged along the length direction of the gap, and the bottom cross-section of the pressing block 11 is a regular "V" shape with a smooth lower end. A lifting mechanism 16 is installed on the top of the pressing block 11. The lifting mechanism 16 is connected to the base 1 through an L-shaped frame 17. In the actual use process, the lifting mechanism 16 is one of an electric push rod, a hydraulic cylinder, and a cylinder. After the plate is fixed, the pressing block 11 will descend under the action of the lifting mechanism 16, so as to perform a bending operation on the plate.

[0030] Further, at least one guiding shaft 18 is arranged in parallel on the side surface of the lifting mechanism 16. The bottom of the guiding shaft 18 is fixed on the top of the pressing block 11, and the other end of the guiding shaft 18 slidably penetrates through the L-shaped frame 17 to guide the lifting operation of the pressing block 11, so that the pressing block 11 can be lifted and lowered stably.

[0031] Receiving grooves 12 are formed at the bottoms on both sides of the pressing block 11, and pressing plates 13 are arranged in the receiving grooves 12. One end of the side of the pressing plate 13 is rotatably connected to the bottom of the receiving groove 12 through a connecting shaft 14, and the pressing plate 13 corresponds to the bearing plate 4. A torsion spring 15 is sleeved on the connecting shaft 14. One end of the torsion spring 15 is fixed on the inner wall of the receiving groove 12, and the other end of the torsion spring 15 is fixed on the pressing plate 13. When the pressing block 11 descends, the pressing plate 13 will horizontally press on the bearing plate 4 to clamp and fix both sides of the bending part of the plate.

[0032] Further, an anti-slip rubber pad is installed on the side of the pressing plate 13 close to the bearing plate 4; an anti-slip rubber pad is installed on the top surface of the bearing plate 4 to increase the frictional force between the bearing plate 4, the pressing plate 13 and the plate, thereby improving the fixing effect of the bearing plate 4 and the pressing plate 13 on the plate.

[0033] Specifically, during use, the bearing plate 4 can be horizontally set under the action of the telescopic mechanism 5, so that the plate can be placed flat on the bearing plate 4 and the side of the plate can be abutted against the inner side of the second limiting plate 10. During this period, the bent portion of the plate is located between the two bearing plates 4. Then, the linear motor 8 is started to make the first limiting plate 9 lean towards the other side of the plate to fix the plate. After that, the lifting mechanism 16 is started to lower the pressing block 11. In the actual use process, when the pressing plate 13 is horizontal, the torsion spring 15 still provides a downward turning force to the pressing plate 13. At this time, the pressing plate 13 will press on the plate placed on the bearing plate 4. As the pressing block 11 continues to press down, the bearing plate 4 will also deflect upward under the action of the telescopic mechanism 5. At this time, a double-power effect is provided for the bending process of the plate. When the bearing plate 4 deflects, the torsion spring 15 will also continue to twist, so as to increase the action of the pressing plate 13 on the plate and make the plate more stable during the bending process. After the bending is completed, the bearing plate 4 is lowered, the pressing block 11 is raised and the first limiting plate 9 is removed to take out the plate.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
