Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a front servo material support device for a bending machine. Background Technology

[0002] There is a Chinese utility patent application with publication number CN216027640U entitled "A Servo Front Material Support System". This servo front material support system includes a lifting mechanism, a rack, slides, and a guide rail. Two slides are mounted on the guide rail, and each slide is equipped with a servo motor. Each servo motor has a gear meshing with the rack. The lifting mechanism has a lifting control handwheel and a rotating mechanism. A lifting locking handle is mounted at the top of the lifting mechanism, and a rotating locking handle is mounted on the rotating mechanism. A material support is mounted at the top of the rotating mechanism. A lifting rack is located within the lifting mechanism, and a lifting gear bonded to the lifting rack is mounted on the lifting control handwheel. The servo motor drives the gear along the rack to move the material support at high speed to a designated position to meet the flipping and changing requirements of the bent sheet material in a robot bending system. However, robots typically hold the sheet material while bending it. If the sheet material needs to be picked up from the same side, the robot has to first flip the sheet material over and place it on the support rack, pick it up from above, and then flip the picked-up sheet material over to bend it. This is time-consuming and affects work efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a high-efficiency servo material support device for the front side of a bending machine.

The traveling mechanism drives the sliding plates to move left and right on the front side of the lower crossbeam of the frame. A bracket is slidably connected to the outer side of the sliding plates. A lifting mechanism is provided between the bracket and the sliding plates. The lifting mechanism drives the bracket to move up and down on the outer side of the sliding plates. Several longitudinally arranged vacuum suction cups are provided on the top of the bracket.

[0006] Preferably, the walking mechanism includes a reducer fixedly connected to the slide plate, a servo motor fixedly connected to the input end of the reducer, a gear fixedly connected to the output end of the reducer, the gear meshing with a rack, the rack fixedly connected to the front side of the lower crossbeam of the frame, and first sliders provided on the upper and lower sides of the slide plate, the first sliders being slidably fitted with first guide rails, the first guide rails being fixedly connected to the front side of the lower crossbeam of the frame.

[0018] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0019] like Figure 1-5 As shown, a front-side servo material support device for a bending machine includes a lower crossbeam 1 of the frame. A pair of sliding plates 2 are slidably connected to the front side of the lower crossbeam. First sliders 21 are installed on the upper and lower sides of the sliding plates. The first sliders are slidably fitted with first guide rails 11, which are fixed to the front side of the lower crossbeam. A traveling mechanism 3 is installed between the sliding plates and the lower crossbeam. The traveling mechanism drives the sliding plates to move left and right on the front side of the lower crossbeam. The traveling mechanism includes a reducer 31 fixed to the sliding plates. A servo motor 32 is fixedly connected to the input end of the reducer, and a gear 33 is fixedly connected to the output end of the reducer. The gear meshes with a rack 34, which is fixedly connected to the front side of the lower crossbeam. A lubrication mechanism 4 for lubricating the rack is installed on the sliding plates to ensure smooth left and right movement of the sliding plates. The lubrication mechanism includes a rotating shaft 41 pivotally connected to the sliding plates. The rotating shaft is mounted on the bottom end of the lower crossbeam towards the rack. The meshing felt gear 42 has an oil passage 411 on the shaft that communicates with the oil hole of the felt gear. The outer side of the slide plate is slidably connected to the bracket 5. A lifting mechanism 6 is installed between the bracket and the slide plate. The lifting mechanism drives the bracket to move up and down on the outer side of the slide plate. The lifting mechanism includes a base 61 fixed to the slide plate. The base is pivotally connected to a vertically arranged lead screw 62. A handwheel 63 is installed at the bottom end of the lead screw extending from the base to facilitate the rotation of the lead screw. The middle part of the lead screw is threadedly connected to a lifting plate 64. Second sliders 65 are installed on the left and right sides of the lifting plate. The second sliders are slidably matched with second guide rails 66. The second guide rails are fixed to the base. A pointer 67 is installed on the side of the lifting plate facing away from the reducer. The side wall of the base is engraved with scale lines (not shown) that cooperate with the pointer to facilitate the control of the vertical displacement of the bracket. Several longitudinally arranged vacuum suction cups 7 are installed on the top of the bracket.

[0020] The specific working process and principle of a front servo material support device for a bending machine: The height of the support is adjusted by rotating the screw via a handwheel according to the working conditions, and then locked using a locking mechanism 8. When the robot is performing bending operations on the sheet metal, to prevent collisions, the support is first moved to the side. When a replacement is needed, the servo motor is started, and the gear and rack transmission drives the slide plate to move to the set position in the middle. The robot places the lifted sheet metal on top of the support, uses a vacuum suction cup to pick up the sheet metal, releases the sheet metal, moves to the set position below the sheet metal, and picks up the sheet metal again to complete the replacement. Because the vacuum suction cup can temporarily fix the sheet metal, the robot arm can also complete the replacement from below the sheet metal, without needing to flip it over to the top of the support for replacement, saving time and improving work efficiency.
