Description

Technical field

The invention relates to a high security bending device, in particular to a high security bending device for electrical equipment parts.

Technician level

Bending devices for electrical equipment parts are currently known. One of the bending devices is described in Chinese Patent Application CN 201210224018.

In electrical equipment, bending parts with different shapes are usually required to meet all types of needs, such as cable clamping, electrical arrangement and installation. Folding of this type of parts is often processed by a bending machine. Conventional bending machines employ a stamping or casting method. In the bending process, it is necessary to cut the workpiece edge to ensure the precision of the machined shape. Thus, an independent blank press disk drive is required. This increases the cost and complexity of the equipment and causes inconvenience to further maintenance. In addition, too long an extension of the bending head can easily cause elastic deformation and other defects in machines that force the bending gear. This adversely affects the accuracy of the processing and the stability of the use of the equipment.

The essence of the invention

The object of the invention is to provide a high security bending device for parts of electrical equipment which can eliminate the drawbacks of existing technologies.

According to the present invention, a high security bending device for electrical equipment parts has two lifting and lowering compression members, the members being fixedly mounted on the upper fastener. The two lifting and lowering compression members are symmetrically mounted relative to the longitudinal axis of the bending device and each includes a threaded sleeve mounted on the upper fastener, a drive screw that fits with a threaded hole in the lower threaded sleeve wall, and a threaded gear below the threaded gear. couplings and is coupled to the drive auger via an instant clutch. The lower end of the drive screw of one of the two lifting and lowering clamping elements is connected to the upper side of the workpiece clamping element through the downward thrust bearing, and the upper end is connected to the lifting and lowering mounting plate through the upward thrust bearing.

The compression projection used to compress both ends of the workpiece is mounted on the left and right sides of the workpiece compression member, respectively. The compression bending drive motor coupled to the bending propeller is mounted between the two lifting and lowering compression members and the lower lower side of the lifting and lowering mounting plate. In addition, the left and right ends of the lifting and lowering mounting plate pass through the vertical sliding gutter in the threaded coupling of the two lifting and lowering compression members respectively and extend into the respective threaded coupling so that the upper end of the respective drive bolt is connected through the upward thrust bearing. The gear is rigidly mounted on the bending drive bolt, which is used to engage the two threaded gears. The bending drive bolt can be inserted with a bending sleeve according to a thread that can slide vertically into the workpiece compression member and is set in the direction of rotation. The protruding portion of the bending joint is mounted at the lower end of the bending sleeve, which is used to join the workpiece supported in the center of the approaching workbench to perform bending processing thereby producing parts of electrical equipment. The upper half of the lifting and lowering mounting plate is connected to the upper fastener via a spring. When the press bending drive motor rotates to drive the propeller of the two lifting and lowering compression members, the propeller can move down toward the threaded sleeve to force the compression projection to press both ends of the workpiece. At this point, the bending joint is not connected to the workpiece. After the bending drive motor continues to rotate when pressed, the instantaneous clutch performs a disconnection of the pinion gear from the drive bolt because the transmitted torque exceeds the set torque. The bending sleeve continues to move downwardly to form a bending joint connected to the workpiece to perform bending processing and manufacture electrical equipment parts. The soundproofing cap is mounted on the outer surface of the press bending drive motor. The upper part of the soundproofing cover is firmly connected to the lifting and lowering mounting plate. The soundproofing layer is built into the soundproofing cap, which is used to press the flex drive motor. The LED indicator light unit is mounted on a higher bracket. The sensor is set in the middle of the oncoming desktop. The sensor is relatively set for the bend portion of the joint. The sensor is an elastic contact type sensor. The sensor is electrically connected to the LED indicator lights on the device. As the bending sleeve moves downward, the bending joint portion is joined to the workpiece to perform the bending process. When the workpiece contacts the sensor, a signal is sent to control the LED indicator light unit to turn on.

In the above device, the drive pinion is used to engage the empty pressing gear and the drive pinion is connected to the drive bolt. In addition, an instantaneous clutch is fitted. In this way, many operating processes can be achieved with only one source of propulsion. It also saves equipment costs and reduces the complexity of the equipment and provides convenience for the repair of the latter. In addition, the propulsion can move up and down during machining, so it can approach the workpiece to shorten the distance between the bending part and the energy motor. This avoids distortion of transmission thread threads due to long-distance transmission, improves machining accuracy and overall robustness of equipment, as well as equipment reliability and service life.

The lower end of the drive screw (81) of one of the two lifting and lowering clamping elements (8) is connected to the upper half of the workpiece clamping element (72) through the downward thrust bearing (811) and the upper end to the lifting and lowering mounting plate (62). through the upward thrust bearing (812). The compression projection (88) used to compress both ends of the workpiece (94) is mounted on the left and right sides of the workpiece compression member (72), respectively.

Further, the left end and the right end of the lifting and lowering mounting plate (62) pass through a vertical sliding gutter (820) in the threaded sleeve (82) of the two lifting and lowering compression members (8) and extended to the respective threaded sleeve (82). to engage the upper end of the respective drive bolt (81) through the upward thrust bearing (812).

The pinion gear (61) is rigidly mounted on the bending gear bolt (7), which is used to engage the two threaded gears (813). The bending drive bolt (7) can be inserted into the bending sleeve (71) by a thread that can slide vertically into the workpiece compression member (72) and is set in the direction of rotation. The protruding portion (711) of the bending joint is mounted at the lower end of the bending sleeve (71), which is used to join the workpiece (94) supported in the middle of the approaching workbench (941) to perform bending processing thereby producing electrical parts. The upper half of the lifting and lowering mounting plate (62) is connected to the upper fastening piece (9) via a spring (629). When the bending drive motor (6) is rotated to drive the drive auger (81) of the two lifting and lowering compression members (8), the drive auger (81) may move downwardly toward the threaded sleeve (82) to force the compression projection (88). both ends of the workpiece (94). At this point, the bending member (711) is not connected to the workpiece. After the bending drive motor (6) is pressed on, the momentary clutch (5) disengages the bolt gear (813) from the drive bolt (81) because the transmitted torque exceeds the set torque. The bending sleeve (71) continues to move downwardly to form a bending member (711) connected to the workpiece (94) to perform bending treatment and manufacture electrical equipment parts. The soundproofing cover (601) is mounted on the outer surface of the compression bending drive motor (6). The upper part (601) of the soundproofing cover is firmly connected to the lifting and lowering mounting plate (62).

As the bending sleeve (71) moves downward, the bending member portion (711) engages with the workpiece (94) to perform the bending process. When the workpiece (94) contacts the sensor (9411), a signal is sent to control the LED indicator light assembly (901) to accelerate and bend processing.

Preferably, when the compression bending drive motor (6) is rotated in reverse, the threaded gear (813) causes the drive screw (81) to move upward to drive the bending joint portion (711) away from the electrical parts made of the workpiece (94).

It is contemplated that the lifting and lowering mounting plate (62) is connected to the vertical sliding panel plane (820) in the threaded sleeve (82) to prevent the mounting plate (62) with respect to the angled lifting and lowering of the threaded sleeve (82).

An instantaneous clutch can be a clutch that can transmit torque at set values. When the moment exceeds the specified value, the clutch retracts. When the torque is below the specified value, the clutch engages. The clutch can be a standard mechanical clutch in this area, such as a friction clutch or an elastic joint clutch. In the above device, the drive pinion is used to engage the empty pressing gear and the drive pinion is connected to the drive bolt. In addition, an instantaneous clutch is fitted. In this way, many operating processes can be achieved with only one source of propulsion. It also saves equipment costs and reduces the complexity of the equipment and provides convenience for the repair of the latter. In addition, the propulsion can move up and down during machining, so it can approach the workpiece to shorten the distance between the bending part and the energy motor. This avoids distortion of transmission thread threads due to long-distance transmission, improves machining accuracy and overall robustness of equipment, as well as equipment reliability and service life. The overall design of the device is compact. It is easy and reliable to use. It can also effectively address gaps in existing technologies.
