Technical Field

[0001] The utility model relates to the technical field of straightening machines, in particular to a feeding device for a straightening machine. Background Art

[0002] A straightening machine is a mechanical device used to correct the straightness of metal profiles, plates, pipes, wires, etc. It applies pressure to the metal material to deform it to achieve the required straightness. The plate straightening machine generally uses a vacuum suction cup for feeding, but most of the existing vacuum suction cup feeding devices cannot adjust the angle and there is a problem of unstable vacuum suction.

[0003] In actual production, the amount of materials hoisted often exceeds 2 tons, and the loading equipment is frequently overloaded. Unexpected sliding may occur during use, causing equipment damage. Each maintenance downtime is 4-6 hours, seriously affecting the straightening machine's production capacity by about 30 tons and indirectly affecting the quenching line's production capacity by about 35 tons.

[0004] Therefore, there is an urgent need for a straightening machine feeding device that can adjust the angle and has a strong load-bearing capacity. Summary of the invention

[0005] The utility model solves the problem that the existing feeding device has a small bearing weight and cannot adjust the angle, and provides a feeding device for a straightening machine, which can adjust the feeding angle and has a large bearing weight.

[0006] In order to achieve the above purpose, the technical solution of the utility model is:

[0007] A feeding device for a straightening machine includes a support unit, a moving unit and a grabbing unit. The support unit includes a horizontal beam, a vertical beam and a supporting bottom plate arranged from top to bottom. The horizontal beam is arranged horizontally, and the two ends of the horizontal beam are fixedly connected to the vertical beam. The bottom end of the vertical beam is movably connected to the supporting bottom plate. The moving unit includes a power device and a swing arm. The power device is fixed on the vertical beam, and the swing arm is fixed on the supporting bottom plate. The power device drives the swing arm to rotate relative to the vertical beam, and a grabbing unit for grabbing materials is arranged on the supporting bottom plate. The power device drives the swing arm to rotate relative to the vertical beam, thereby driving the supporting bottom plate to rotate relative to the vertical beam, and the grabbing unit on the supporting bottom plate grabs the plate-like material.

[0008] Furthermore, the power device is a hydraulic cylinder, and the top end of the swing arm is rotatably connected to an output shaft of the hydraulic cylinder. The hydraulic cylinder drives the swing arm.

[0009] Furthermore, the swing arm is in a right-angle trapezoidal shape, and the right-angle side of the swing arm is fixed on the supporting bottom plate. The swing arm drives the supporting bottom plate to move.

[0010] Furthermore, the gripping unit comprises a plurality of vacuum suction cups, which are evenly arranged on the supporting bottom plate and fixedly connected to the supporting bottom plate. The vacuum suction cups are used to suck up materials.

[0011] Furthermore, a base is fixedly arranged on the vertical beam, and the base is rotatably connected to the fixed end of the power device. When the power device drives the swing arm, the fixed end of the power device rotates relative to the base.

[0012] Furthermore, a rotating shaft is fixedly arranged at the bottom of the vertical beam, and a bearing seat matching the rotating shaft is fixedly arranged on the supporting bottom plate. The connecting portion is used to connect the vertical beam.

[0013] Furthermore, swing arms are arranged on both sides of the vertical beam, and the bearing seat is fixedly arranged between the two swing arms. The power device drives the swing arms, and the swing drives the supporting bottom plate and the connecting part to rotate around the rotation axis.

[0014] Through the above technical solution, the beneficial effects of the utility model are:

[0015] The utility model is provided with a supporting unit, a moving unit and a grabbing unit. The cross beam is horizontally arranged, and the two ends of the cross beam are fixedly connected with vertical beams. The bottom end of the vertical beam is rotatably connected to the supporting bottom plate through a connecting part. The various components of the utility model are firmly connected. Compared with the loading device with a single vertical beam structure, the load-bearing weight is greater.

[0016] The utility model is provided with a power device on the vertical beam, and the power device controls the rotation angle of the supporting bottom plate through the swing arm, so as to grab the inclined plate. Compared with the existing loading device, the contact area between the vacuum suction cup and the plate is larger, the connection is more stable, and the problem of the plate slipping is avoided.
