Description

Technical Field

[0001] The utility model relates to the technical field of plate grooving, in particular to a plate grooving device before bending. Background Art

[0002] Sheet metal bending and notching is a crucial technology in metalworking, primarily used in the aviation, automotive, electronics, and home appliance industries. The core steps include determining the bend location, creating the bend notch, and bending along the bend. The bend location is marked on the metal sheet according to the desired shape and size. A V-shaped groove is then cut at the marked bend location. The depth of this groove typically requires approximately half the sheet metal wall thickness to prevent breakage or deformation during the bending process.

[0003] The patent with application number 202123325530.8 discloses a plate grooving machine, which includes a bracket, a carrier plate for placing workpieces is provided on the top of the bracket, and a sliding assembly is provided between the carrier plate and the bracket; a grooving mechanism is provided on one side of the bracket, and the grooving mechanism is located below the workpiece conveying path; the grooving mechanism includes a cutting frame, a cutting knife located on the top of the cutting frame, and a driving member located below the cutting knife and driving the cutting knife to rotate.

[0004] However, this technical solution uses a driving member to move the plate to perform grooving, and there is a lack of fixation of the plate during the grooving process, which causes the plate to loosen due to the extrusion force during the grooving process. In addition, the grooving depth required for plates of different thicknesses is different, and the existing technical solution is difficult to adjust the grooving depth of the plate. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology and provide a device for grooving plates before bending. The device realizes the functions of plate cutting positioning and depth adjustment through the synchronously moving cutting and clamping plate structure and the adjustable cutting knife structure, thereby solving the problems of loose plate cutting and difficult adjustment of cutting depth.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A device for grooving a plate before bending comprises a processing table and a movable frame arranged above the processing table, wherein a plurality of slide grooves are provided on the processing table, and a movable plate is provided below the processing table, an electric push rod is symmetrically installed on the bottom end of the movable plate, and a driving plate connected to the electric push rod is slidably inserted into the bottom end of the movable plate, a clamping plate is symmetrically fixed on the top end of the driving plate through the through slot, and a slider fixed to the slide rod is adjustably installed on the bottom end of the movable frame.

[0008] Preferably, a slide groove is provided at the bottom end of the movable frame, and a motor is installed on the side wall of the movable frame, and a lead screw connected to the motor is embedded in the slide groove.

[0009] Preferably, the top end of the slider is inserted into the slide groove, and the lead screw is threadedly inserted into the slider.

[0010] Preferably, a lifting frame is fitted and plugged into the bottom end of the sliding block, and a second hydraulic rod connected to the lifting frame is embedded in the sliding block, and a slotting knife is embedded and fixed at the bottom end of the lifting frame.

[0011] Preferably, a plurality of connecting grooves are provided on the side wall of the sliding block, and positioning grooves are provided on both ends of the lifting frame.

[0012] Preferably, a rigid support plate is inserted into the connecting groove for damping, and the rigid support plate abuts against the inner wall of the positioning groove.

[0013] Preferably, the top end of the movable plate is slidably inserted in the through groove, and a sliding rod slidably inserted in the movable plate is fixed to the side wall of the slider.

[0014] Preferably, support plates are symmetrically fixed to the top of the processing table, and first hydraulic rods connected to the movable frame are fixed to the side walls of the two support plates.

[0015] The beneficial effects of the present invention are:

[0016] (1) The utility model is provided with a movable frame and a processing table, and a slider is provided at the bottom end of the movable frame. After the motor on the movable frame is started, the slider is driven to move by the lead screw, and during the movement, the slide rod drives the movable plate and the clamping plate to move synchronously, so that the slotting knife at the bottom end of the slider and the clamping plate remain corresponding after the movement, and at the same time, the electric push rod is started to drive the drive plate to move downward, so that the plate at the top end of the processing table remains fixed, thereby improving the stability of the plate during the slotting process.

[0017] (2) The utility model is provided with a lifting frame which is slidably installed at the bottom end of the slider, and the slotting knife is fixed at the bottom end of the lifting frame. The rigid positioning plate is inserted into the connecting groove with a damping force and is protruded in the positioning groove. The second hydraulic rod in the slider drives the lifting frame and the slotting knife to move downward until the inner wall of the positioning groove abuts against the rigid positioning plate. The rigid positioning plate is inserted into the connecting groove at different positions, thereby adjusting the height of the slotting knife and the slotting depth of the plate. The utility model is suitable for slotting processing of plates with different depths. When the first hydraulic rod drives the movable frame and the slotting knife to move horizontally to process the plate, the slide bar slides in the movable plate, thereby keeping the movable plate and the clamping plate stable.

[0018] In summary, the utility model has the advantages of stable processing and convenient adjustment of the groove depth. BRIEF DESCRIPTION OF THE DRAWINGS
