Description

Technical Field

[0001] The utility model relates to an automatic material pushing device for a bending machine. Background Art

[0002] The bending machine is an important equipment for bending thin plates. A bracket needs to be installed at the front end of the bending machine. In the prior art, the plate is supported by the bracket, and then the plate is manually pushed into the bending position. The bending of the plate is completed by pressing down the bending machine. When bending, the plate will rise and fall back after the bending is completed. After falling back, the plate needs to be pushed in again.

[0003] We found in actual operation that the separate bracket support needs to be pushed in manually and cannot be pushed in automatically, which makes the operation relatively difficult.

[0004] To this end, we have designed an automatic material pushing device for the bending machine which can automatically push in the sheet material to be bent. Utility Model Content

A servo motor for driving the screw to rotate is installed on the outside of one side of the bracket plate. The screw has two sections of threaded parts with opposite rotation directions. Each section of the threaded part is equipped with more than one pushing unit. When the screw rotates, the pushing units equipped on the two threaded parts are displaced in opposite directions. A T-shaped slide rail is installed between the two bracket plates, and the pushing unit is equipped with the T-shaped slide rail.

[0030] like Figure 1 and Figure 2 The automatic material pushing device of a bending machine shown in the figure comprises a lateral displacement driving device 1 and a material pushing unit 2 driven by the lateral displacement driving device 1. The lateral displacement driving device 1 comprises two front and rear bracket plates 11, a screw 12 is rotatably arranged between the two bracket plates 11, a servo motor 13 for driving the screw 12 to rotate is installed on the outside of one side of the bracket plate 11, the screw 12 has two sections of threaded parts 14 with opposite rotation directions, and each section of the threaded part 14 is equipped with more than one material pushing unit 2, see Figure 1 and Figure 2 As shown, in this embodiment, each section of the threaded portion 14 cooperates with a pushing unit 2. When the screw 12 rotates, the pushing units 2 cooperated on the two sections of the threaded portion are displaced in the opposite direction. A T-shaped slide rail 15 is installed between the two bracket plates 11, and the pushing unit 2 cooperates with the T-shaped slide rail 15.

[0031] In the above technical solution, the two pushing units 2 are driven to move closer to or farther away from each other by the rotation of the screw rod 12, thereby meeting the support requirements of the plates to be bent of different widths.

[0032] The T-shaped slide rail 15 can play a role of sliding guide, thereby improving the sliding stability of the pusher unit 2.

[0033] See also Figure 3As shown, the pushing unit 2 includes a bracket body 21, a threaded sleeve 22 matching the threaded portion 14 is provided at the bottom of the bracket body 21, a slider 23 matching the T-shaped slide rail 15 is provided at the rear end of the bracket body 21, and the slider 23 slides along the T-shaped slide rail 15, and a frame 24 is provided at the upper end of the bracket body 21. A plurality of transmission rollers 25 are provided inside the frame 24, and a first bearing (not shown) is provided between the transmission rollers 25 and the frame 21, and a conveyor belt 26 is installed between the plurality of transmission rollers 25, and a servo reduction motor 27 for connecting the front end transmission rollers 25 is installed outside the frame 24.

[0034] In the above technical solution, the front end transmission roller 25 is driven to rotate by the operation of the servo reduction motor 27, so that the conveyor belt 26 rotates to drive the plate to be bent to move.

[0035] See also Figure 4 As shown, the bracket body 21 includes a lower bracket body 210 and an upper bracket body 211, the top of the lower bracket body 211 is provided with a groove 212, and an electric push rod 213 is installed at the bottom of the groove 212, and guide holes 214 are provided at both ends of the top of the lower bracket body 210, the upper end of the upper bracket body 211 is connected to the frame 24, and the lower end of the upper bracket body 211 is provided with a guide rod 215, the guide rod 215 is inserted into the guide hole 214, and slides vertically along the guide hole 214, the telescopic end of the electric push rod 213 is fixed to the bottom of the upper bracket body 211, the slider 23 is installed at the rear end of the lower bracket body 210, and the threaded sleeve 22 is detachably installed at the bottom of the lower bracket body 210.

[0036] In the above technical solution, when bending, the plate needs to fit the lower mold of the bending machine. Therefore, in the above technical solution, the support height of the conveyor belt 26 can be changed by extending and retracting the electric push rod 213, so that the lower end surface of the plate just fits the lower mold of the bending machine.

[0037] See also Figure 4 As shown, a rib plate 244 is provided between the upper bracket body 211 and the frame 24 .

[0038] The ribs 244 may increase structural strength.

[0039] See also Figure 4As shown, a first guide hole 241 is provided on the end face of the frame 24, and two first guide holes 241 are provided. A first guide rod 242 is cooperated with the first guide hole 241, and a first frame 243 is installed at the end of the first guide rod 242 away from the first guide hole 241. A plurality of support rollers 245 are rotatably installed in the first frame 243, and the outer sleeve of the support roller 245 is provided with a friction sleeve 246 made of rubber material, and the support height of the friction sleeve 246 is consistent with the support height of the conveyor belt 26. A first electric push rod 247 is installed at the bottom of the frame 24, and the output end of the first electric push rod 247 is connected to the first frame 243.

[0040] The above technical solution is mainly aimed at the bending needs of plates with larger widths and meets the support needs of the plates. When the plates are bent, the end of the plates away from the bending machine will be lifted up. After a bending is completed, the plates will fall back. At this time, the conveyor belt 26 and the friction sleeve 246 can effectively receive the fallen plates to prevent them from falling.

[0041] The surface of the conveyor belt 26 is rough.

[0042] The conveyor belt 26 with a rough surface can generate sufficient friction.

[0043] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
