Description

Technical Field

[0001] The utility model relates to the technical field of workbenches, in particular to a workbench which is convenient for replacing bending moulds. Background Art

[0002] A press brake is a versatile processing equipment for bending sheet metal. It can bend a variety of shapes using simple molds. The upper module is equipped with a compensation mechanism to ensure high bending accuracy. Users only need to equip a variety of molds to bend sheet metal into various shapes. Punching, shearing and other processes are also possible. Therefore, press brakes are widely used in the automotive, machinery, shipbuilding, electrical appliances, light industry and decoration industries for bending and forming metal sheets. The mold is assembled on the workbench.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 5 The utility model provides an embodiment of a workbench for convenient replacement of bending molds, comprising a workbench 1, a slide groove 6 is opened in the middle of which a lower mold 3 is installed inside through a moving mechanism, and an L-shaped plate 2 is welded on the workbench 1, and an upper mold 4 is installed on the L-shaped plate 2 through an adjusting component, and the adjusting component comprises a hydraulic telescopic rod 5 symmetrically arranged on the L-shaped plate 2, and the output end of the hydraulic telescopic rod 5 is connected to the upper mold 4 through a mounting plate 21, which can be conveniently moved up and down, thereby facilitating the bending operation, and adapting to the lower mold 3 to facilitate the bending operation on the workpiece, and a positioning component is installed on the side wall of the L-shaped plate 2, and a plug-in mechanism is also provided on the workbench 1, which matches the lower mold 3, can facilitate its positioning and fixation, and also facilitate subsequent replacement operations, and for the upper mold 4, it can also be installed through the same positioning component and plug-in mechanism as the lower mold 3 (not shown in the figure), which can be conveniently replaced.

[0023] See also Figure 1-Figure 5In order to facilitate the movement and adjustment of the lower mold 3, it is convenient to replace and transport it. It is relatively convenient. A linear guide device 12 of the moving mechanism is installed inside the slide 6, on which guide rail sliders 13 are symmetrically arranged. The top of the guide rail slider 13 is bonded with an anti-slip pad 16, which can facilitate the placement of the lower mold 3 and ensure stability during the transportation process. It will not slide. It can be driven by a linear motor to achieve the reciprocating movement of the guide rail slider 13. It can also be achieved by other methods such as reciprocating screws. It is a relatively mature technology and will not be described here. In order to ensure stability during movement, guide plates 14 are welded on both side walls of the guide rail slider 13, and the corresponding side walls of the slide 6 are provided with guide grooves 8 for the reciprocating sliding of the guide plates 14.

[0024] See also Figure 1-Figure 5 The upper and lower molds 3 are connected by a plurality of screw terminals, and the upper and lower molds 3 are connected by a plurality of screw terminals, and the upper and lower molds 3 are connected by a plurality of screw terminals.

[0025] Working principle: When the utility model is in use, the linear guide device 12 works, and the guide slider 13 slides in the upper slide groove 6. At the same time, the guide plate 14 slides in the guide groove 8 to ensure stability during the movement. The lower mold 3 can be moved, and it stops moving after moving to the middle of the workbench 1. One side wall contacts the rubber pad 11 of the top plate 10, and then the electric push rod 17 extends, moving the moving plate 18, and the plug-in column 19 extends into the plug-in hole 15. It continues to extend to cooperate with the top plate 10 to position and fix it, thereby preventing it from being When the lower mold 3 is displaced during the bending process, the hydraulic telescopic rod 5 is extended to move the upper mold 4 downward, and the bending process can be carried out in conjunction with the lower mold 3. When it needs to be replaced, the electric push rod 17 can be retracted to reset the movable plate 18, and the plug-in column 19 can be moved out of the plug-in hole 15, thereby losing the positioning and fixation of the lower mold 3. Then, the linear guide device 12 can be used to move it, making it convenient to replace it. After replacement, the above operation can be repeated to position and fix the replaced lower mold 3 without affecting the bending process.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
