Description

Technical Field

[0001] The utility model relates to the technical field of waveguide tube processing, in particular to a waveguide tube bending device. Background Art

[0002] At present, there is no corresponding mature equipment for bending BJ32 type (tube cross section greater than 3cm and less than 6cm) hard rectangular aluminum waveguide tubes. Mature bending equipment is basically suitable for bending small-sized tubes, with a size range of hard rectangles with a tube cross section less than 3cm or round tubes of corresponding sizes. After bending, BJ32 type will have wrinkles and cracks to varying degrees on its inner wall and bending arc, which is not allowed for waveguide transmission.

[0003] The existing technical solutions cannot grasp the bending state of the waveguide in real time during the waveguide bending process, and can only be completed by one strike according to the initial set parameters. The actual angle deviates greatly from the set angle and cannot be adjusted at any time, resulting in low product qualification rate and consistency accuracy. In addition, the existing waveguide feeding adopts an AC motor to drive the ball screw to rotate, and drives the waveguide to feed linearly with the assistance of the clamping mechanism. The frequency and strength of the tapping on the two sides and the top are based on the initial set values. The waveguide bending radius and angle are formed at one time and cannot be adjusted in time, resulting in low product qualification rate and consistency accuracy.

[0004] Therefore, how to provide a waveguide bending device that can accurately detect and control the bending angle and accuracy during the wide side or narrow side bending process. Utility Model Content

[0013] On the basis of the above scheme, it also includes: a PLC control device for receiving data feedback from the angle sensor to control the feeding speed of the feeding mechanism and the driving frequency of the power mechanism.

[0016] A knife seat disposed on the slide seat;

[0017] and an upper knife, a left knife and a right knife arranged on the knife seat.

[0018] Based on the above solution, the frame is integrally formed.

[0019] The utility model adopts a servo motor to drive the feeding mechanism, and the clamping mechanism is used as an auxiliary mechanism to drive the waveguide to feed linearly. The servo motor drives the knocking mechanism to knock the corresponding position of the pipe according to the frequency set by the program. The angle sensor measures the angle in real time and feeds it back to the PLC control device. The program compares the real-time value and the set value, and adjusts the knocking frequency and feeding amount in time according to the actual angle and accuracy requirements to ensure that the actual bending angle meets the parameter range specified by the technical requirements.

[0025] like Figure 1 As shown, a waveguide bending device includes a feeding mechanism 1 for feeding the waveguide 7, a supporting mechanism 2 for preventing the waveguide 7 from deflecting and twisting during the feeding process, a clamping mechanism 3 arranged on the feeding mechanism 1 for ensuring that the waveguide 7 does not move forward and backward during the feeding process, a striking mechanism 4 arranged on the upper part of the waveguide 7 for striking the waveguide 7, and a power mechanism 5 arranged on the upper part of the clamping mechanism 3 for providing power to the striking mechanism 4.

[0026] As a specific implementation scheme, it also includes: an angle sensor 6 arranged at the front end of the waveguide 7 for real-time measurement of the bending angle of the waveguide 7. The angle sensor 6 is mainly used to measure the bending angle of the waveguide 7 in real time and feed the data back to the PLC control device in real time to ensure that the final data is consistent with the set data, which can improve the overall efficiency and product consistency. The angle sensor 6 is installed as a whole at the front end of the waveguide.

[0027] like Figure 3 As shown, as a specific implementation scheme, the power mechanism 5 includes a frame 5-1, a motor 5-2 arranged on the frame 5-1, a transmission shaft 5-3 arranged on the top of the frame 5-1, a first pulley arranged on the motor shaft of the motor 5-2, a second pulley 5-4 arranged on the transmission shaft 5-3, a belt 5-5 arranged on the first pulley and the second pulley 5-4 for driving the transmission shaft 5-3 to rotate through the motor 5-2, a connecting rod 5-6 arranged at the other end of the transmission shaft 5-3, and a slide 5-7 arranged on the connecting rod 5-6. Specifically, the transmission shaft 5-3 is driven to rotate by the first pulley, the second pulley 5-4 and the belt 5-5 under the drive of the motor 5-2, and the connecting part of the transmission shaft 5-3 and the connecting rod 5-6 is an eccentric structure. During the rotation of the transmission shaft 5-3, the connecting rod 5-6 and the slide 5-7 are driven to move up and down.

[0028] As a specific implementation scheme, the knocking mechanism 4 includes a knife seat 4-1 arranged on the slide seat 5-7 and an upper knife 4-2, a left knife 4-3 and a right knife 4-4 arranged on the knife seat 4-1.

[0029] Specifically, the knocking mechanism 4 knocks on the rectangular waveguide under the drive of the connecting rod 5-6, and the upper knife 4-2 drives the knife seat 5-7 and the upper knife 4-2 to move up and down through the connecting rod 5-6 to knock on the upper surface of the waveguide, and the left knife 4-3 and the right knife 4-4 are squeezed during the downward movement of the upper knife 4-2 to achieve inward knocking, completing the knocking on the two sides of the waveguide, and then completing the bending of the waveguide.

[0030] Specifically, the waveguide bending device includes a feeding mechanism 1, which is used as a feeding mechanism for the pipe during the bending process of the waveguide 7, to ensure that the knocking points of the knocking mechanism are uniform and non-overlapping, and to control the bending radius, and is installed as a whole at the upper rear end of the equipment frame; a supporting mechanism 2, which is mainly used to ensure that the waveguide 7 does not deflect and twist during the feeding process, and to ensure that the inner wall of the waveguide 7 does not deform during the knocking process of the knocking mechanism, and is installed as a whole at the upper part of the equipment frame, at the front end of the feeding mechanism 1; a clamping mechanism 3, which is used to ensure that the waveguide 7 does not deflect and twist during the feeding process, and to ensure that the inner wall of the waveguide 7 does not deform during the knocking process of the knocking mechanism. The front and rear displacement, feeding is stable and reliable, and the whole is located on the feeding mechanism 1, and moves forward and backward with the feeding mechanism 1 as a whole; the power mechanism 5, the main function of which is to provide power for the knocking mechanism 4, to ensure that the knocking force of the knocking mechanism 4 is uniform and stable when working, and the force can be adjusted. The whole is located at the front end of the device, on the upper part of the clamping mechanism 3; the knocking mechanism 4, the main function of which is that the waveguide 7 moves through the feeding mechanism 1 under the action of the clamping mechanism 3, so that the waveguide 7 moves forward at a certain speed, and bends downward at a certain angle (such as Figure 2As shown in the figure, the whole is located at the lower part of the power mechanism 5 and outside the supporting mechanism 2; among them, the waveguide 7, as the verification part of the equipment performance and structure, runs through the above-mentioned mechanism and connects various parts to make it operate effectively; in this embodiment, the frame is an integral casting structure. The running guide rails of the power mechanism 5, the knocking mechanism 4 and the waveguide feeding mechanism 1 are all dovetail guide rails scraped and ground after casting, ensuring that the lifting accuracy of the power mechanism 5 and the motion guide accuracy of the feeding mechanism 1 and the knocking mechanism 4 do not change during operation. The waveguide 7 is supported by the supporting mechanism 2 and fed forward at a certain set speed under the joint action of the clamping mechanism 3 and the feeding mechanism 1. The power mechanism 5 drives the knocking mechanism 4 through the motor and the internal mechanism under the set program with a certain frequency and knocking force (the knocking frequency is intuitively expressed as the interval between the knocking indentations on the two sides and the upper part of the waveguide 7. Under the premise of a certain feeding speed, the higher the knocking frequency, the denser the indentations, the greater the elongation of the upper part of the waveguide 7, and the smaller the bending radius; conversely, the lower the knocking frequency, the sparser the indentations, the smaller the elongation of the upper part of the waveguide 7, and the larger the bending radius. The knocking force is the feeding amount of the knocking mechanism each time, which is intuitively expressed as the depth of the knocking indentations on the two sides and the upper part of the waveguide 7. Under the premise of a certain feeding speed, the greater the knocking force, the deeper the indentations, the greater the elongation of the upper part of the waveguide 7, and the smaller the bending radius; conversely, the smaller the knocking force, the shallower the indentations, the smaller the elongation of the upper part of the waveguide 7, and the larger the bending radius). The two sides and the upper end surface of the waveguide 7 are continuously knocked to make it extend and then deform (an inner mold is embedded in the waveguide 7 through the supporting mechanism 2 to ensure that the internal shape and inner wall of the waveguide 7 do not deform during the knocking process) and bend. The angle sensor 6 measures the angle in real time and feeds back to the PLC control device. Through angle comparison, the program is adjusted in real time to ensure that the set angle matches the actual angle.

[0031] The bending radius and angle are mainly determined by the relationship between the knocking mechanism 4 and the feeding mechanism 1. When the knocking force is constant, the faster the feeding speed, the larger the bending radius, and the slower the feeding speed, the smaller the bending radius; conversely, when the feeding speed is constant, the greater the knocking force, the smaller the bending radius, and the smaller the knocking force, the larger the bending radius.

[0032] Through the real-time angle detection of the front-end angle sensor 6, a real-time feedback is provided to the PLC control device, and a closed-loop control is achieved in the program control; the angle can be set arbitrarily between 0-180° as required, and the angle value can be displayed on the display screen in real time, avoiding errors and cumbersome procedures caused by manual measurement, thereby improving work efficiency and reducing labor intensity, and ensuring product quality. Compared with the existing technology, it fundamentally solves the accuracy and consistency problems of waveguide bending pipes, and is an effective technical improvement.

[0033] The utility model waveguide bending equipment adopts a servo motor to drive the feeding mechanism, and the clamping mechanism 3 is used as an auxiliary mechanism to drive the waveguide to feed linearly. The servo motor drives the knocking mechanism 4 to knock the corresponding position of the pipe according to the frequency set by the program. The angle sensor 6 measures the angle in real time and feeds it back to the PLC control device. The program compares the real-time value and the set value, and adjusts the knocking frequency and feeding amount in time according to the actual angle and accuracy requirements to ensure that the actual bending angle meets the parameter range specified by the technical requirements.

[0034] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
