Technical Field

[0001] This utility model relates to the field of sheet metal processing, specifically an improved sheet metal blanking and cutting mechanism. Background Technology

[0002] Existing blanking equipment for processing sheet metal parts occupies a large area and is costly. Furthermore, existing equipment for processing tubular parts is limited to cutting tubular components, restricting its application. Therefore, those skilled in the art have developed an improved sheet metal blanking and cutting mechanism to address the problems mentioned in the background section. Utility Model Content

[0003] The purpose of this invention is to provide an improved sheet metal cutting mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An improved sheet metal cutting mechanism includes a fixed base and a rotating support disk rotatably mounted inside the fixed base via bearings. Four T-shaped guide grooves are evenly spaced along the circumference on one side wall of the rotating support disk. A T-shaped slider is slidably mounted inside each T-shaped guide groove. A retainer is connected to the T-shaped slider via screws, and a fixed pressure plate is connected to the retainer via screws. A roller seat is integrally formed at the center of the rotating support disk on the fixed pressure plate. A support roller is rotatably connected to the roller seat via bearings. A cylinder support plate is fixedly connected to the end of the T-shaped guide groove away from the center of the rotating support disk. A clamping cylinder is fixedly connected to the cylinder support plate, and the telescopic end of the clamping cylinder passes through the cylinder support plate and is fixedly connected to the retainer.

[0006] As a further embodiment of this utility model: the thickness of the card holder at one of the cross-shaped positions is greater than that of the card holder at the other cross-shaped position; the card holder is provided with multiple card slots at equal intervals on one side of the fixed pressure plate; and the fixed pressure plate is integrally formed with multiple card protrusions that cooperate with the card slots on one side of the card holder.

[0007] As a further embodiment of this utility model: a hollow driven gear is fixedly connected to the other side wall of the rotating support disk, a motor support is fixedly connected to the back plate on one side of the rotating support disk, a rotary servo motor is connected to the motor support by screws, and a driving gear that meshes with the driven gear is connected to the output shaft of the rotary servo motor by a key.

[0008] As a further embodiment of this utility model: a walking clamping and feeding mechanism is provided on one side of the fixed base. The walking clamping and feeding mechanism has a four-jaw pneumatic chuck and a gear and rack walking mechanism. The four-jaw pneumatic chuck is coaxial with the rotating support plate, and an L-shaped jaw for clamping plate-shaped materials is connected to the four-jaw pneumatic chuck by screws.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This utility model can be installed in existing tubular parts cutting devices. By using four clamping cylinders to drive the support rollers on four fixed pressure plates to move towards the center, the plate-shaped parts can be radially clamped. The cutting head can then cut holes or irregular shapes into the plate-shaped parts. The support rollers ensure that the plate-shaped parts are supported without affecting their axial movement along the rotating support plate. This greatly expands the original equipment's limitation of only being able to process tubular parts. At the same time, it also solves the problem that existing plate parts can only be processed on large plate cutting machines, greatly reducing processing costs.

[0011] 2. In this utility model, the card holder is provided with multiple snap-fit ​​grooves at equal intervals on one side of the fixed pressure plate, and the fixed pressure plate is integrally formed with multiple snap-fit ​​protrusions that cooperate with the snap-fit ​​grooves on one side of the card holder. By loosening the locking screws, the cooperation between different snap-fit ​​grooves and snap-fit ​​protrusions can be adjusted to adjust the support stroke, which greatly increases the range of applications.

[0018] Please see Figures 1-4 An improved sheet metal cutting mechanism includes a fixed base 2 and a rotating support disk 4 rotatably mounted inside the fixed base 2 via bearings. T-shaped guide grooves 401 are evenly spaced along the circumference on one side wall of the rotating support disk 4. T-shaped sliders 9 are slidably mounted inside the T-shaped guide grooves 401. A mounting base 10 is connected to the T-shaped slider 9 via screws. A fixed pressure plate 11 is connected to the mounting base 10 via screws. A roller seat 1102 is integrally formed at the center of the rotating support disk 4 on the fixed pressure plate 11. A support roller 12 is rotatably connected to the roller seat 1102 via bearings. A cylinder support plate 14 is fixedly connected to one end of the T-shaped guide groove 401 away from the center of the rotating support disk 4. A clamping cylinder 13 is fixedly connected to the cylinder support plate 14. The telescopic end of the clamping cylinder 13 passes through the cylinder support plate 14 and is fixedly connected to the mounting base 10.

[0019] By adopting the above technical solution, it can be installed in the original tubular parts cutting device. The four clamping cylinders 13 drive the support rollers 12 on the four fixed pressure plates 11 to move towards the center, which can radially clamp the plate-shaped parts. The cutting head can then cut holes or irregular shapes on the surface of the plate-shaped parts. The setting of the support rollers 12 can ensure that the plate-shaped parts are supported without affecting their axial movement along the rotating support plate 4. This greatly expands the original equipment's limitation of only being able to process tubular parts. At the same time, it also solves the problem that existing plate parts can only be processed on large plate cutting machines, greatly reducing processing costs.

[0020] One of the card holders 10 at a cross intersection is thicker than the other, ensuring that the support rollers 12 can avoid each other and not interfere when pressed. The card holder 10 has multiple slots 1001 at equal intervals on one side of the fixed pressure plate 11. The fixed pressure plate 11 has multiple locking protrusions 1101 integrally formed on one side of the card holder 10, which cooperate with the slots 1001. By loosening the locking screw, the cooperation between different slots 1001 and locking protrusions 1101 can be adjusted to adjust the support stroke, greatly increasing the range of applications.

[0021] A hollow driven gear 5 is fixedly connected to the other side wall of the rotating support disk 4. A motor support 6 is fixedly connected to the back plate on one side of the rotating support disk 4. A rotary servo motor 7 is connected to the motor support 6 by screws. A drive gear 8 that meshes with the driven gear 5 is connected to the output shaft of the rotary servo motor 7 by a key. The rotary servo motor 7 can move to drive the drive gear 8 to rotate, and then drive the rotating support disk 4 to rotate under the drive of the driven gear 5, so as to realize the rotation adjustment of the plate-shaped parts.

[0022] Among them, a walking clamping and feeding mechanism 1 is provided on one side of the fixed base 2. The walking clamping and feeding mechanism 1 has a four-jaw pneumatic chuck 101 and a gear rack walking mechanism 103. The four-jaw pneumatic chuck 101 is coaxial with the rotating support plate 4, and an L-shaped jaw 102 for clamping plate-shaped materials is connected to the four-jaw pneumatic chuck 101 by screws.

[0023] A schematic diagram of the installed utility model is shown below. Figure 5 As shown, during use, the rotation angle of the rotary servo motor 7 is controlled. In order to ensure that the air pipe of the clamping cylinder 13 is not twisted during rotation, the rotary servo motor 7 can only rotate 180 degrees back and forth. During operation, the rotary servo motor 7 can drive the plate to rotate, thereby realizing the adjustment of its angle. In conjunction with the cutting head with the top horizontal movement and the walking clamping and feeding mechanism 1, a three-axis motion cutting operation can be realized.

[0024] In this embodiment, the gear and rack walking mechanism 103 in the walking clamping and feeding mechanism 1 is the prior art. It mainly drives the gear to work through the motor. The gear meshes with the rack and can drive it to walk along the guide support track.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
