DETAILED DESCRIPTION

[0026] The technical solution of the present invention is further described in detail below in conjunction with specific embodiments:

[0027] Example 1

[0028] Please see the attached Figure 1 -Attached Figure 7A bending device for steel structure connectors includes a processing table 1, two parallel guide frames 14 are fixed on the processing table 1, and a number of plates 5 are slidably installed between the two guide frames 14. A door-shaped bearing frame 3 is fixed on the processing table 1, and a lifting column 17 is installed on the door-shaped bearing frame 3. A bending pressure block 10 is fixed to the bottom of the lifting column 17. A clearance channel 45 vertically corresponding to the bending pressure block 10 is opened on the processing table 1. A lifting component for driving the lifting column 17 to move vertically is installed on the door-shaped bearing frame 3. A horizontally arranged lifting frame 40 is fixed on the lifting column 17. The lifting frame 40 is installed by an elastic push component. There is a stop pressure plate 18 for temporarily limiting the plate 5. A servo motor 21 is installed at the bottom of the processing table 1. The servo motor 21 is connected to a conveying assembly for driving the plate 5 to slide stepwise toward the makeshift channel 45. Two symmetrically arranged side push rollers 20 are installed in the makeshift channel 45. The processing table 1 is equipped with an auxiliary bending assembly for driving the side push rollers 20 to push toward the push plate 6. Two symmetrically arranged side clamping assemblies are installed on the guide frame 14. The side clamping assemblies are used to limit the position of the plate 5 before bending. A product box 2 for collecting the bent plate 5 is installed at the bottom of the processing table 1.

[0029] When the plate 5 for processing the steel structure connector is bent by this device, the plates 5 are arranged one by one on the processing table 1, and the plates 5 are located between the guide frames 14. The plates 5 are transported one by one to the bottom of the bending block 10 by the provided conveying assembly, and the bending pressure lifting column 17 is driven by the lifting assembly to drive the bending block 10 to move downward, thereby realizing the bending processing of the plates 5.

[0030] Specifically, the lifting assembly of the device includes a driving motor 4 fixed on a door-shaped carrier frame 3, a rotating disk 7 is rotatably installed on the door-shaped carrier frame 3, and the rotating disk 7 is connected to the output shaft of the driving motor 4 through a pulley mechanism 8. A circular frame 15 is fixed on the lifting column 17, and a pin 16 is slidably installed in the circular frame 15. The pin 16 is eccentrically fixed on the rotating disk 7.

[0031] The driving motor 4 can drive the rotating disk 7 to rotate through the pulley mechanism 8, and the rotating disk 7 drives the pin 16 to rotate. At this time, the pin 16 drives the circular frame 15 to reciprocate vertically, so that the circular frame 15 drives the lifting column 17 to lift vertically, and the lifting column 17 moves vertically downward and presses and bends the plate 5. The pressed plate 5 extends toward the yield channel 45. Under the action of the conveying component, the next plate 5 pushes the previous formed plate 5 to move, so that the formed plate 5 is pushed into the product box 2 to achieve an automatic collection effect, which greatly improves the production efficiency of steel structure connectors.

[0032] The auxiliary bending assembly of this device includes a guide sleeve 30 fixed to the bottom of the processing table 1, a U-shaped roller frame 29 is slidably installed on the guide sleeve 30, the side push roller 20 is rotatably installed on the U-shaped roller frame 29, a bridge plate 32 is fixed on the guide sleeve 30, and a connecting spring 31 is fixed between the bridge plate 32 and the U-shaped roller frame 29.

[0033] In addition, the auxiliary bending assembly also includes a push frame 9 slidably mounted on the processing table 1, and the push frame 9 slides and abuts against the end of the U-shaped roller frame 29 away from the side push roller 20. A square hole 27 is opened on the push frame 9, and a transmission wedge 11 corresponding to the square hole 27 is fixed on the bending pressure block 10. A reset spring 28 is fixed between the push frame 9 and the processing table 1.

[0034] Through the above-mentioned structural setting, when the bending pressure block 10 moves downward and contacts the plate 5 to bend the plate 5, the transmission wedge block 11 moves vertically downward and extends into the square hole 27. At this time, the transmission wedge block 11 pushes the push frame 9. At this time, the push frame 9 moves toward the U-shaped roller frame 29 and pushes it. The U-shaped roller frame 29 drives the side push roller 20 to move toward the plate 5 under the action of the guide sleeve 30, thereby achieving a lateral push on the bent plate 5, effectively promoting the plate 5 to bend better toward the bending pressure block 10, and greatly improving the processing effect of the bending pressure block 10.

[0035] Example 2

[0036] Please see the attached Figure 1 -Attached Figure 7 On the basis of Example 1, in addition, the conveying assembly of the present device includes two pulleys 23 rotatably mounted on the bottom of the processing table 1, and a conveying belt 22 is connected to the two pulleys 23 with a transmission sleeve. A sliding frame 24 slidingly connected to the processing table 1 is fixed on the conveying belt 22, and a pusher plate 6 for pushing the plate 5 is fixed on the sliding frame 24. An incomplete gear 25 is coaxially fixed to the output shaft of the servo motor 21, a rotating shaft 42 is coaxially fixed to the pulley 23, and a transmission gear 26 intermittently meshing with the incomplete gear 25 is coaxially fixed to the rotating shaft 42.

[0037] The servo motor 21 can drive the incomplete gear 25 to rotate, and the incomplete gear 25 intermittently engages with the transmission gear 26 for transmission, so that the transmission gear 26 drives the pulley 23 to rotate intermittently, and the pulley 23 drives the conveyor belt 22 to convey in a step-by-step manner. At this time, the conveyor belt 22 drives the sliding frame 24 and the pusher plate 6 to move, so that the pusher plate 6 pushes the plate 5 to slide, realizing the step-by-step automatic feeding operation of the plate 5, and the plate 5 can be automatically bent one by one.

[0038] In addition, an extension plate 44 is fixed to the bottom of the processing table 1 , on which a friction pressure block 43 in frictional contact with the rotating shaft 42 is slidably mounted, and a push spring 33 is fixed between the friction pressure block 43 and the extension plate 44 .

[0039] During the rotation of the rotating shaft 42, the rotating shaft 42 is in frictional contact with the friction pressure block 43. Under the elastic pushing action of the pushing spring 33, the friction pressure block 43 applies friction force to the rotating shaft 42, thereby achieving an effective braking effect when the pulley 23 is at rest, thereby ensuring stable feeding and bending operations of the plate 5.

[0040] In addition, the lateral clamping assembly of the present device includes a sleeve plate 36 fixed on the processing table 1, a guide rod 37 is slidably mounted on the sleeve plate 36, a lateral clamping block 34 opposite to the side wall of the plate 5 is fixed on the guide rod 37, a spring ring 35 is fixed between the lateral clamping block 34 and the sleeve plate 36, and a slope 41 is provided at the end of the lateral clamping block 34.

[0041] During the process of the plate 5 being transported and entering under the bending pressure block 10, the plate 5 realizes that the lateral clamping block 34 is away from the plate 5 through the push slope 41, and finally the plate 5 is located between the two lateral clamping blocks 34. Under the elastic push action of the spring coil 35, the two lateral clamping blocks 34 clamp and limit the plate 5, further improving the stability of the plate 5.

[0042] In addition, a vertically arranged wedge plate 13 is fixed on the lateral clamping block 34, and a horizontal push plate 12 vertically opposite to the wedge surface of the wedge plate 13 is fixed on the bending pressure block 10. During the downward movement of the bending pressure block 10, the horizontal push plate 12 moves vertically downward and pushes the wedge plate 13. The two wedge plates 13 drive the lateral clamping block 34 away from the plate 5, achieving an unlocking effect when the plate 5 is bent, avoiding interference of the lateral clamping block 34 with the deformation process of the plate 5, and ensuring the smooth bending processing of the plate 5.

[0043] In addition, the elastic pressure component of the device includes a pressure rod 19 that slides vertically through the lifting frame 40, the stop pressure plate 18 is fixed to the lower end of the pressure rod 19, a top plate 38 is fixed to the top of the pressure rod 19, and a vertical spring 39 is fixed between the top plate 38 and the lifting frame 40 and is sleeved on the pressure rod 19.

[0044] Before the bending pressure block 10 moves down and contacts the plate 5, the set stop pressure plate 18 first contacts another adjacent plate 5, and then the lifting frame 40 moves vertically downward, the vertical spring 39 deforms and stretches, and the elastic force of the vertical spring 39 is applied to the top plate 38, and the top plate 38 pushes against the pressure rod 19, and finally the stop pressure plate 18 presses and fixes the plate 5, ensuring that the plate 5 located under the bending pressure block 10 can be bent smoothly without being interfered with by other plates 5, thereby greatly improving the processing quality of the plate 5.

[0045] In summary, the present invention realizes the downward bending processing of the sheet material 5 being conveyed in a step-by-step manner by means of the vertical reciprocating movement of the bending pressure block 10. During the bending process, the transmission wedge block 11 can push the pushing frame 9, so that the pushing frame 9 pushes the U-shaped roller frame 29 toward the sheet material 5 to move and perform the auxiliary bending operation on the side wall of the sheet material 5, which effectively promotes the sheet material 5 to bend better toward the bending pressure block 10, and greatly improves the bending and forming processing quality of the sheet material 5. In the present invention, the sheet material 5 can be conveyed step by step to the bottom of the bending pressure block 10 under the action of the conveying assembly, realizing the one-by-one and automatic bending operation of the sheet material 5, greatly improving the bending processing efficiency of the sheet material 5, and when the sheet material 5 moves to the bottom of the bending pressure block 10, the elastic pressing assembly can elastically limit the sheet material 5, and at the same time, the stop pressure plate 18 can press and limit the adjacent sheet material 5, effectively ensuring the stability of the bending process of the sheet material 5 and achieving high-quality bending and forming effects.
