Description

Technical Field

[0001] The invention relates to the technical field of hardware material strip processing, in particular to a hardware material strip groove wheel folding mechanism. Background Art

[0002] Hardware strips are made of alloy material. Due to the high hardness of the hardware material, it is usually necessary to use a folding mechanism to bend the hardware strips during the production process to form them into a specified shape.

[0003] The power of most folding mechanisms uses compressed air to drive the cylinder to move up and down, thereby driving the upper and lower folding plates to move to achieve the folding of the hardware strips. Using cylinders as the power of the folding mechanism is theoretically completely feasible, but there are many problems in actual use: the compressed air cannot be maintained at a stable value during the use of the mechanism, resulting in inconsistent speed of the cylinder during operation, long-term high-frequency reciprocating motion of the cylinder, severe cylinder heat, and a significant reduction in the service life of the cylinder piston, resulting in frequent replacement of the cylinder, and the use of cylinders as power. The solenoid valve reciprocates frequently and its service life is shortened. The use of cylinders as power requires the addition of buffers and hard limit devices to limit the cylinder, resulting in a lot of noise in the equipment. Summary of the invention

[0004] The object of the present invention is to provide a hardware material strip groove wheel folding mechanism to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a hardware material belt groove wheel folding mechanism, comprising a base plate, a servo motor and a sliding plate, a fixed panel is arranged on the front outer side of the base plate, the servo motor is arranged on the top rear section of the fixed panel, the output end of the servo motor is connected with an eccentric groove wheel, and the front outer side of the eccentric rotating wheel is connected with a lifting plate, connecting seats are arranged on both sides of the rear of the lifting plate, reciprocating slide rails are connected on both sides of the middle part of the fixed panel, the sliding plate is arranged on the front end of the lifting plate, and the top outer side of the sliding plate is connected with an upper pressing cylinder, the bottom outer side of the upper pressing cylinder is arranged with an upper buffer block, pressing slide rails are arranged on both sides of the front part of the sliding plate, the front outer side of the upper buffer block is connected with an upper folding clamp, and oil pressure buffers are arranged on both sides of the middle part of the fixed panel.

[0006] Furthermore, the servo motor is rotationally connected to the eccentric sheave wheel, and the eccentric sheave wheel is sleeve-connected to the lifting plate.

[0007] Furthermore, the lifting plate and the connecting seat are integrated, and the connecting seat is slidably connected to the reciprocating slide rail.

[0008] Furthermore, the sliding plate and the lifting plate are fixedly connected by bolts, and the sliding plate and the pressing slide rail are integrated.

[0009] Furthermore, the upper buffer block is integrated with the upper material folding clamp, and the upper buffer block is slidably connected to the material pressing slide rail.

[0010] Furthermore, a fixing plate is provided on the outer side of the bottom of the fixed panel, and a lower pressing cylinder is connected to the outer side of the bottom of the fixing plate, a lower buffer block is connected to the outer side of the top of the lower pressing cylinder, and a lower folding clamp is connected to the outer side of the front of the lower buffer block.

[0011] Furthermore, the size and shape of the lower buffer block are consistent with those of the upper buffer block, and the lower buffer block is integrated with the lower folding material clamp.

[0012] Furthermore, the oil pressure buffers are symmetrically distributed along the center line of the fixed panel, and the oil pressure buffers are in contact with the outer end surfaces of the upper buffer block and the lower buffer block.

[0013] The present invention provides a hardware material belt groove wheel folding mechanism, which has the following beneficial effects:

[0014] 1. The eccentric groove wheel of the present invention can drive the lifting plate to move up and down reciprocatingly on the reciprocating slide rail through the connecting seat at the rear end during rotation. Since the sliding plate and the lifting plate are fixedly connected by bolts, the lifting plate can drive the sliding plate to move together during lifting. During the displacement of the sliding plate, the upper folding material clamp can press the fixed hardware material strip, so that the equipment can fold the hardware material strip. During the entire folding process, the eccentric groove wheel can be used to make the servo motor rotate a full circle in one direction to complete the reciprocating lifting and lowering of the lifting plate, which can avoid the influence of the servo motor's reciprocating rotation on the service life of the motor, thereby improving the service life of the equipment.

[0015] 2. The equipment of the present invention bends the hardware strip by utilizing the displacement force of the servo motor during rotation. The upper pressing cylinder and the lower pressing cylinder only act on the upper folding clamp and the lower pressing cylinder to fix the hardware strip. Compared with the traditional method of directly pressing and forming with the cylinder, it can avoid the problems of inconsistent speed of the cylinder during operation, frequent reciprocating motion of the solenoid valve, shortened service life, long-term high-frequency reciprocating motion of the cylinder, severe heating of the cylinder, and greatly reduced service life of the cylinder piston, which leads to frequent replacement of the cylinder, etc.

[0016] 3. The present invention adopts a servo motor to rotate back and forth to drive the lifting plate to lift and lower the material, which can avoid the large noise generated when the cylinder is working, and the oil pressure buffers on both sides of the fixed panel can buffer the displacement of the upper buffer block and the lower buffer block respectively, which makes the noise generated when the upper buffer block and the lower buffer block are working smaller, which can greatly reduce the interference of noise to the staff around the equipment.

[0017] 4. During the operation of the equipment of the present invention, the lifting speed of the lifting plate can be adjusted by adjusting the speed of the servo motor, and then the force of the upper folding clamp when pressing down can be adjusted. This allows the equipment to adjust the pressing force of the equipment through simple speed adjustment, which can greatly shorten the debugging workload of the operating personnel.

[0025] The specific operation is as follows: after the metal material strip to be bent is placed between the upper folding material clamp 12 and the lower folding material clamp 16, the upper pressing cylinder 9 is operated to make the upper buffer block 10 slide in the pressing slide rail 11 at the front end of the sliding plate 8, so that the upper buffer block 10 can drive the upper folding material clamp 12 to move in the direction of the metal material strip. At the same time, the lower pressing cylinder 14 on the fixed plate 13 is operated to make the lower buffer block 15 drive the lower folding material clamp 16 to move in the direction of the metal material strip. After the folding material clamp 12 and the lower folding material clamp 16 are both fitted with the metal material strip, the two can clamp and fix the metal material strip. At this time, the servo motor 3 at the rear end of the fixed panel 2 is operated. The eccentric groove wheel 4 is made to rotate, and during the rotation process, the eccentric groove wheel 4 can drive the lifting plate 5 to move up and down reciprocatingly on the reciprocating slide rail 7 through the connecting seat 6 at the rear end. Because the sliding plate 8 is fixedly connected to the lifting plate 5 by bolts, the lifting plate 5 can drive the sliding plate 8 to move together during the lifting process, and the sliding plate 8 can make the upper folding material clamp 12 press the fixed hardware material strip during the displacement process, so that the equipment can fold the hardware material strip. During the entire folding process, the equipment can make the servo motor 3 rotate a full circle in one direction through the use of the eccentric groove wheel 4 to complete the reciprocating lifting and lowering of the lifting plate 5, which can avoid the servo motor 3 from rotating back and forth The impact on the service life of the motor can improve the service life of the equipment. In addition, the equipment bends the hardware strip by utilizing the displacement force of the servo motor 3 when it rotates. The upper pressing cylinder 9 and the lower pressing cylinder 14 only act on the upper folding clamp 12 and the lower pressing cylinder 14 to fix the hardware strip. Compared with the traditional method of directly pressing and forming with a cylinder, it can avoid the speed inconsistency of the cylinder during operation, the frequent reciprocating action of the solenoid valve, the shortened service life, the long-term high-frequency reciprocating action of the cylinder, the serious heating of the cylinder, and the significant reduction in the use time of the cylinder piston, resulting in frequent replacement of the cylinder, etc. In addition, the servo motor 3 is used to reciprocate back and forth to drive the lifting plate 5 The reciprocating lifting and lowering for folding materials can avoid the loud noise generated when the cylinder is working, and the oil pressure buffers 17 on both sides of the fixed panel 2 can buffer the displacement of the upper buffer block 10 and the lower buffer block 15 respectively, which makes the noise generated by the upper buffer block 10 and the lower buffer block 15 smaller when working, which can greatly reduce the interference of noise to the staff around the equipment. During the operation of the equipment, by adjusting the speed of the servo motor 3, the lifting speed of the lifting plate 5 can be adjusted, and then the force of the upper folding clamp when pressing down can be adjusted, which allows the equipment to adjust the pressing force of the equipment through simple speed adjustment, which can greatly shorten the debugging workload of the operator.

[0026] In summary, when the metal material belt groove wheel folding mechanism is used, the metal material belt that needs to be bent is first placed between the upper folding material clamping grasping 12 and the lower folding material clamping grasping 16, and then the upper pressing cylinder 9 is operated, which can make the upper buffer block 10 slide in the pressing slide rail 11 at the front end of the sliding plate 8, so that the upper buffer block 10 can drive the upper folding material clamping grasping 12 to move in the direction of the metal material belt, and at the same time, the lower pressing cylinder 14 on the fixed plate 13 is operated, which can make the lower buffer block 15 drive the lower folding material clamping grasping 16 to move in the direction of the metal material belt, and after the folding material clamping grasping 12 and the lower folding material clamping grasping 16 are both fitted with the metal material belt, the two can clamp and fix the metal material belt, at this time, the servo motor 3 at the rear end of the fixed panel 2 is operated, which can make the eccentric groove wheel 4 rotate, and during the rotation process, the eccentric groove wheel 4 can drive the lifting plate 5 to reciprocate up and down on the reciprocating slide rail 7 through the connecting seat 6 at the rear end;

[0027] Then, because the sliding plate 8 is fixedly connected with the lifting plate 5 by bolts, the lifting plate 5 can drive the sliding plate 8 to move together during the lifting process, and the sliding plate 8 can make the upper folding material clamp 12 press the fixed hardware material belt during the displacement process, so that the equipment can fold the hardware material belt. During the whole folding process, the servo motor 3 can rotate a full circle in one direction through the use of the eccentric groove wheel 4 to complete the reciprocating lifting of the lifting plate 5, which can avoid the influence of the reciprocating rotation of the servo motor 3 on the service life of the motor, which can improve the service life of the equipment;

[0028] Next, because the present equipment bends the metal strip by utilizing the displacement force of the servo motor 3 when it rotates, the upper pressing cylinder 9 and the lower pressing cylinder 14 only act on the upper folding material clamp 12 and the lower pressing cylinder 14 to fix the metal strip. Compared with the traditional method of directly pressing and forming by using the cylinder, it can avoid the problems of inconsistent speed of the cylinder during operation, frequent reciprocating motion of the solenoid valve, shortened service life, long-term high-frequency reciprocating motion of the cylinder, serious heating of the cylinder, and greatly reduced use time of the cylinder piston, resulting in frequent replacement of the cylinder, etc. In addition, by using the servo motor 3 to reciprocate back and forth to drive the reciprocating lifting of the lifting plate 5 to fold the material, the large noise generated when the cylinder is working can be avoided, and the oil pressure buffers 17 on both sides of the fixed panel 2 can buffer the displacement of the upper buffer block 10 and the lower buffer block 15 respectively, which makes the noise generated by the upper buffer block 10 and the lower buffer block 15 smaller when working, which can greatly reduce the interference of noise to the staff around the equipment;

[0029] Finally, during the operation of the equipment, by adjusting the speed of the servo motor 3, the lifting speed of the lifting plate 5 can be adjusted, and then the force of the upper folding clamp when pressing down can be adjusted. This allows the equipment to adjust the pressing force of the equipment through simple speed adjustment, which can greatly shorten the debugging workload of the operator.
