Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and more specifically to a discharge structure of a CNC bending machine. Background Technology

[0002] A bending machine is a machine that can bend thin plates. After the workpiece is bent, it slides out of the bending machine along the discharge plate, completing the workpiece discharge action.

[0003] A search revealed an existing patent (publication number: CN217797764U) disclosing the discharge structure of a CNC bending machine. During operation, air blowing and suction devices are installed above and below the discharge plate, respectively, to clean the top and bottom of the sheet metal, ensuring a clean surface after discharge and eliminating the need for manual cleaning, thus improving efficiency. However, the inventors discovered the following problem with the existing technology during the development of this invention: The aforementioned CNC bending machine discharge structure uses airflow to clean the surface ash and slag of the workpiece to ensure cleanliness after subsequent discharge. However, for workpieces that have undergone bending, some paint or rust may lift up after bending. This ash and slag remains connected to the workpiece, and relying solely on airflow is insufficient to separate them, leading to incomplete cleaning and affecting the cleanliness of the workpiece surface after discharge.

[0004] In view of this, this utility model proposes a discharge structure for a CNC bending machine to solve this problem. Utility Model Content

The contact switch and the vibrator are electrically connected.

[0008] As a further description of the above technical solution: a slag collection box is placed on the surface of the substrate, and a slag discharge groove is opened on the surface of the baffle near the first discharge plate. When the baffle is closed, the bottom end of the baffle extends into the interior of the slag discharge gap, and the slag discharge groove corresponds to the upper opening position of the slag collection box. Some of the slag on the surface of the workpiece, which is composed of rust and paint layers, will detach from the workpiece during the falling collision process, and the slag can enter the interior of the slag collection box along the slag discharge groove on the surface of the baffle to complete the slag collection work.

[0010] As a further description of the above technical solution: a limiting slide bar is fixedly installed on the surface of the first discharge plate, and the side of the gantry away from the transverse screw is slidably connected to the surface of the limiting slide bar; by setting the limiting slide bar, the stability of the gantry when it moves can be ensured.

[0025] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The discharge structure of the CNC bending machine involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Reference Figures 1 to 6 The present invention provides a discharge structure for a CNC bending machine, including a base plate 1. The surface of the base plate 1 is provided with four mounting holes 26, which are arranged in a rectangular array on the surface of the base plate 1.

[0027] By setting mounting holes 26 and inserting bolts inside, the substrate 1 can be easily installed and fixed, completing the installation of the overall discharge structure. During installation, the overall discharge structure is connected to the external power control system.

[0028] The top part of the substrate 1 is fixedly mounted with a first discharge plate 2 and a second discharge plate 3. The second discharge plate 3 corresponds to the lower end of the first discharge plate 2, and a slag discharge gap is reserved between the lower end of the first discharge plate 2 and the higher end of the second discharge plate 3. The surface of the first discharge plate 2 is symmetrically rotatably connected with a mounting shaft 4, and a baffle 5 for blocking the lower end of the first discharge plate 2 is fixedly mounted on the surface of the mounting shaft 4.

[0029] A slag collection box 15 is placed on the surface of the substrate 1. A slag discharge groove is opened on the surface of the baffle 5 on the side close to the first discharge plate 2. When the baffle 5 is closed, the bottom end of the baffle 5 extends into the interior of the slag discharge gap, and the slag discharge groove corresponds to the upper opening position of the slag collection box 15.

[0030] When the CNC bending machine is in use, the workpiece after being bent by the CNC bending machine falls on the surface of the first discharge plate 2 and is blocked by the baffle 5. The ash and slag on the surface of the workpiece, which consists of rust and paint, will separate from the workpiece during the collision process, and the ash and slag will enter the slag collection box 15 along the slag groove on the surface of the baffle 5. Since some of the ash and slag on the surface of the workpiece separate from the workpiece during discharge, the cleanliness of the subsequent workpiece discharge can be improved.

[0031] The surface of the first discharge plate 2 is provided with a flipping component that drives the baffle 5 to flip up and open.

[0032] The flipping assembly includes a drive box 16 fixedly installed on the back of the first discharge plate 2. The mounting shaft 4 is rotatably connected to the drive box 16. A drive motor 17 is fixedly installed on the top of the drive box 16. The output shaft of the drive motor 17 extends into the interior of the drive box 16 and a worm gear 18 is fixedly installed thereon. A worm wheel 19 is fixedly installed on the surface of the mounting shaft 4. The worm gear 18 meshes with the worm wheel 19.

[0033] Furthermore, by setting up a flipping component, the drive motor 17 drives the worm gear 18 to rotate. Based on the meshing of the worm gear 18 and the worm wheel 19, the mounting shaft 4 and the baffle 5 can be driven to rotate, thereby driving the baffle 5 to open, so that the bottom side of the first discharge plate 2 is open, which facilitates the smooth discharge of the workpiece.

[0034] A cleaning component is provided on the outer wall of the first discharge plate 2.

[0035] The cleaning assembly includes a transverse screw 6 rotatably mounted on the front of the first discharge plate 2, and a servo motor 7 that drives the transverse screw 6 to rotate is fixedly mounted on the surface of the first discharge plate 2. A gantry 8 is threadedly connected to the surface of the transverse screw 6.

[0036] A limiting slide bar 20 is fixedly installed on the surface of the first discharge plate 2, and the side of the gantry frame 8 away from the transverse screw 6 is slidably connected to the surface of the limiting slide bar 20.

[0037] Furthermore, by setting the limit slide bar 20, the stability of the gantry frame 8 during movement can be ensured.

[0038] The gantry frame 8 is positioned above the first discharge plate 2. The surface of the gantry frame 8 is fitted with hydraulic rods 9, and the telescopic end of the hydraulic rods 9 is fixedly installed with a lifting seat 10.

[0039] A balance slide bar 21 is fixedly installed on the upper surface of the lifting seat 10, and the balance slide bar 21 is slidably connected to the gantry frame 8.

[0040] Furthermore, by setting the balance slide bar 21, the stability of the lifting seat 10 during movement can be ensured, and the anti-torsion protection effect can be achieved for the telescopic end of the hydraulic rod 9.

[0041] A duct 22 is fixedly installed on the right side of the lifting platform 10. An air outlet 23 is opened at the bottom end of the duct 22. An air pump 24 is fixedly installed on the surface of the gantry frame 8. The air outlet of the air pump 24 is connected to the duct 22 through a spring hose.

[0042] Furthermore, by setting up air duct 22 and air pump 24, the air pump 24 blows airflow from air outlet 23 to the surface of the first discharge plate 2. By utilizing the wind force, it can promote the separation of ash and slag from the workpiece and improve the cleanliness of the workpiece surface.

[0043] The bottom end of the lifting seat 10 is provided with a telescopic groove, and a rubber plate 11 is slidably connected to the bottom end of the telescopic groove. A vibrator 12 is fixedly installed on the top of the rubber plate 11, and a trigger spring 13 is fixedly installed on the upper surface of the rubber plate 11. A contact switch 14 is fixedly installed on the inner top wall of the telescopic groove of the lifting seat 10. The positions of the trigger spring 13 and the contact switch 14 are corresponding, and the contact switch 14 is electrically connected to the vibrator 12.

[0044] It is worth noting that by setting up a cleaning component, the hydraulic rod 9 extends to drive the lifting seat 10 to move downward, so that the rubber plate 11 contacts the surface of the workpiece. Then the rubber plate 11 retracts into the lifting seat 10, so that the trigger spring 13 contacts the contact switch 14 to start the vibrator 12. The vibration is transmitted to the surface of the workpiece through the rubber plate 11, which promotes the separation of the ash and slag composed of rust and paint from the workpiece. The ash and slag enter the slag collection box 15 along the slag groove on the surface of the baffle 5. After the baffle 5 is opened, the workpiece can slide down under the action of gravity and then slide out from the second discharge plate 3, thereby ensuring the cleanliness of the workpiece after discharge.

[0045] It is worth noting that after vibration for a certain period of time, the hydraulic rod 9 is controlled to contract according to the cleanliness of the workpiece surface, so that the rubber plate 11 is separated from the workpiece. Then, the servo motor 7 drives the transverse screw 6 to rotate, thereby driving the gantry 8 to move. By moving the gantry 8, the vibration position can be adjusted, so that the vibration position can be adjusted according to the actual situation.

[0046] A support spring 25 is fixedly installed on the inner top wall of the expansion groove, and the bottom end of the support spring 25 is fixed to the top end of the rubber plate 11.

[0047] Furthermore, by setting a support spring 25, the rubber plate 11 can be flexibly supported downwards, and the rubber plate 11 can be restored after the hydraulic rod 9 retracts.

[0048] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
