Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, and more specifically, to an angle measuring device for a novel bending machine. Background Art

[0002] A bending machine is a mechanical device for bending metal sheets. It mainly consists of a frame, a workbench, bending dies, a hydraulic system, etc. The bending machine provides strong pressure through the hydraulic system, so that the upper die and the lower die press the metal sheet into the required angle and shape.

[0003] At present, to detect the bending angle after the workpiece is bent, the workpiece needs to be removed for measurement. If there is a deviation, manual calibration of the bending is required. This is not only troublesome to operate, but also reduces the bending efficiency of the bending machine. Summary of the Utility Model

The technical problem to be solved by the utility model is that at present, to detect the bending angle after the workpiece is bent, the workpiece needs to be removed for measurement. If there is a deviation, manual calibration of the bending is required. This is not only troublesome to operate, but also reduces the bending efficiency of the bending machine.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

[0006] The angle measuring device for a novel bending machine includes a base. A top plate is fixedly installed on the top surface of the base. A hydraulic rod is fixedly installed on the top surface of the top plate. A sliding plate is fixedly installed at the bottom end of the hydraulic rod. A pressing plate is fixedly installed at the center of the bottom surface of the sliding plate. Two moving plates are symmetrically and slidably connected to the bottom surface of the sliding plate. The sliding plate drives the two moving plates to slide symmetrically through a driving mechanism. A plurality of laser sensors are symmetrically installed on both sides of the pressing plate. A displacement sensor is fixedly installed on the outer side of the sliding plate.

A plurality of electric telescopic rods are symmetrically installed on the bottom surface of each clamping plate. A display controller is fixedly installed on the outer side of the base.

[0007] Such as Figures 1-5As shown, the implementation method is specifically as follows: By setting a pressing plate, a hydraulic rod, and a clamping plate, the pressing plate moves downward, and the plate is lifted off the ground through the clamping plate, so as to perform a bending process on the plate. The height of the clamping plate can be controlled by an electric telescopic rod, so as to facilitate the adjustment of the bending angle. Since the pressing plate is located at the center, the plate is bent with the pressing plate as the axis point to form a right triangle. At the same time, the distance between the moving plate and the pressing plate and the distance that the pressing plate presses downward after contacting the plate are measured by a displacement sensor and a laser sensor respectively. Then, the lengths of the two right-angled sides of the right triangle can be measured, and the bending angle of the plate can be accurately measured in real time by the display controller and displayed on the display controller.

[0008] In a preferred implementation mode, the driving mechanism includes a plurality of grooves, and the plurality of grooves are symmetrically opened on the bottom surface of the sliding plate. A double-headed screw is rotatably connected in each groove.

[0010] In a preferred implementation mode, a plurality of through grooves are symmetrically opened on the sliding plate, and each limiting rod is movably connected in the corresponding through groove.

[0011] In a preferred implementation mode, a plurality of spring telescopic rods are symmetrically installed on the bottom surface of each display controller, and the bottom ends of the plurality of spring telescopic rods on the same side are jointly installed with a fixing plate.

[0012] In a preferred implementation mode, the synchronization mechanism includes a plurality of synchronous wheels, and each synchronous wheel is installed at one end of the double-headed screw corresponding in position. The plurality of synchronous wheels are jointly sleeved with a synchronous belt.

[0013] In a preferred implementation mode, a plurality of third chutes are symmetrically opened on the bottom surface of the base, and each electric telescopic rod is slidably connected in the corresponding electric telescopic rod.

[0014] In a preferred implementation mode, a motor is fixedly installed on the outside of the sliding plate, and the output shaft of the motor is connected to one of the double-headed screws.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. The utility model realizes the extrusion of the pressing plate on the plate material through devices such as a laser sensor, a displacement sensor, a display controller, a sliding plate, and a pressing plate, so as to bend the plate material. While bending, the distance between the pressing plate and the moving plate is measured by the laser sensor, and at the same time, the downward moving distance of the pressing plate after contacting the plate material is measured by the displacement sensor, thereby obtaining the lengths of the two right-angled sides of a right-angled triangle. Furthermore, the bending angle of the plate material can be measured, and it is calculated and displayed on the display controller in real time through the display controller, facilitating the observation of the operator.

[0017] 2. The utility model realizes the rotation of the double-headed screw through devices such as a double-headed screw, a limiting rod, and an electric telescopic rod, which can change the distance between each moving plate and the pressing plate. At the same time, the clamping plate is driven to move synchronously by the limiting rod, and the height of the clamping plate can be changed by the electric telescopic rod. Therefore, when realizing the obtuse-angle bending of the plate material, the moving plates can be controlled to move away from each other, so that the clamping position of the plate material is far from the bending position, and vice versa, the moving plates can be controlled to move closer to each other.

[0018] In summary, when the utility model is in use, the operation is simple. The bending angle of the plate material can be determined by measuring the two right-angled sides of the right-angled triangle, and it is calculated and displayed on the display controller in real time through the display controller, facilitating the observation of the operator. At the same time, the bending angle of the plate material can be flexibly changed by changing the position of the moving plate. Brief Description of the Drawings

Specific embodiments

[0025] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0026] Refer to Figures 1-5 , an angle measuring device for a new type of bending machine, including a base 1, a top plate 2 is fixedly installed on the top surface of the base 1, a hydraulic rod 3 is fixedly installed on the top surface of the top plate 2, a sliding plate 4 is fixedly installed at the bottom end of the hydraulic rod 3, a pressing plate 12 is fixedly installed at the center of the bottom surface of the sliding plate 4, two moving plates 15 are symmetrically and slidably connected to the bottom surface of the sliding plate 4, and the sliding plate 4 drives the two moving plates 15 to slide symmetrically through a driving mechanism. A plurality of laser sensors 13 are symmetrically installed on both sides of the pressing plate 12, a displacement sensor 14 is fixedly installed outside the sliding plate 4, two clamping plates 7 are symmetrically and slidably connected to the top surface of the base 1, and the positions of the clamping plates 7 correspond to the bottom surfaces of the moving plates 15 respectively. A plurality of electric telescopic rods 24 are symmetrically installed on the bottom surface of each clamping plate 7, and a display controller 5 is fixedly installed outside the base 1.

[0027] As Figures 1-5 shown, the specific implementation method is as follows: By setting the pressing plate 12, the hydraulic rod 3, and the clamping plate 7, the pressing plate 12 moves downward, and the clamping plate 7 is used to lift the plate off the ground, so as to perform bending treatment on the plate. The height of the clamping plate 7 can be controlled by the electric telescopic rod 24, so as to facilitate the adjustment of the bending angle. Since the pressing plate 12 is located at the center, the plate is bent with the pressing plate 12 as the pivot point to form a right triangle. At the same time, the displacement sensor 14 and the laser sensor 13 are used to measure the distances between the moving plate 15 and the pressing plate 12, and the distance that the pressing plate 12 presses downward after contacting the plate respectively. Then, the lengths of the two right-angled sides of the right triangle can be measured, and the bending angle of the plate can be accurately measured in real time by the display controller 5 and displayed on the display controller 5.

[0028] The driving mechanism includes a plurality of grooves 11, and the plurality of grooves 11 are symmetrically arranged on the bottom surface of the sliding plate 4. A double-headed screw 10 is rotatably connected in each groove 11. A plurality of threaded sleeves 16 are symmetrically installed on the bottom surface of each moving plate 15, and each threaded sleeve 16 is threadedly connected to the corresponding double-headed screw 10. The plurality of double-headed screws 10 are connected by a synchronization mechanism.

[0029] Through the movement of the double-headed screw 10 through the threaded sleeve 16, the two moving plates 15 are driven to slide symmetrically.

[0030] A plurality of second sliding grooves 22 are symmetrically arranged on the top surface of the base 1, and a plurality of first sliding grooves 9 are symmetrically arranged on the bottom surface of the top plate 2. A plurality of limiting rods 6 are slidably connected to the second sliding grooves 22, and the other end of each limiting rod 6 passes through the clamping plate 7 and the moving plate 15 and is slidably connected in the corresponding first sliding groove 9.

[0031] It should be noted that the movement of the moving plate 15 can drive the limiting rod 6 to slide in the second sliding groove 22 and the first sliding groove 9, and drive the clamping plate 7 and the moving plate 15 to slide synchronously, so that the moving plate 15 and the clamping plate 7 are always in a corresponding state.

[0032] A plurality of through grooves 8 are symmetrically arranged on the sliding plate 4, and each limiting rod 6 is movably connected in the corresponding through groove 8.

[0033] A plurality of spring telescopic rods 17 are symmetrically installed on the bottom surface of each display controller 5, and the bottom ends of the plurality of spring telescopic rods 17 on the same side are jointly installed with a fixing plate 18.

[0034] Through the acting force of the spring in the spring telescopic rod 17, the fixing plate 18 and the clamping plate 7 can effectively clamp the plate, avoiding shaking during bending.

[0035] The synchronization mechanism includes a plurality of synchronous wheels 21, and each synchronous wheel 21 is installed at one end of the corresponding double-headed screw 10. The plurality of synchronous wheels 21 are jointly sleeved with a synchronous belt 20.

[0037] A motor 19 is fixedly installed on the outside of the sliding plate 4, and the output shaft of the motor 19 is connected to one of the double-headed screws 10.

[0038] When the utility model is in use, first place the plate on the top surfaces of the two clamping plates 7, support the plate by the two clamping plates 7, then start the hydraulic rod 3 to make the sliding plate 4 move downward. Then, the fixed plate 18 installed on the bottom surface of the moving plate 15 through the spring telescopic rod 17 and the clamping plate 7 clamp the plate. Then, the plate is extruded by the pressing plate 12 to achieve bending. While bending, the distance between the pressing plate 12 and the moving plate 15 is measured by the laser sensor 13, and at the same time, the downward moving distance of the pressing plate 12 after contacting the plate is measured by the displacement sensor 14, so as to obtain the lengths of the two right-angled sides of the right-angled triangle, and then the bending angle of the plate can be measured and calculated and displayed on the display controller 5 in real time by the display controller 5, which is convenient for the operator to observe;

[0039] At the same time, the motor 19 can be started to drive each double-headed screw 10 to rotate synchronously through the synchronous belt 20 and the synchronous pulley 21, so as to adjust the distance between the moving plate 15 and the pressing plate 12. At the same time, when the moving plate 15 moves, the clamping plate 7 is driven to move by the limiting rod 6, so that the change of the fixed positions on both sides of the plate can be realized. At the same time, the support height of the clamping plate 7 can be adjusted by the electric telescopic rod 24 installed at the bottom, so as to adjust the bending angle of the plate. When an obtuse angle is required, the two moving plates 15 can be controlled to move away from each other, and vice versa, the two moving plates 15 can be controlled to move closer to each other.

Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways.
