Description

Technical Field

[0001] The utility model belongs to the technical field of sheet metal processing, and more specifically, particularly relates to sheet metal cutting equipment. Background Art

[0002] Sheet metal is a processing technology. Sheet metal has not yet had a relatively complete definition. According to a definition in a foreign professional journal, it can be defined as: Sheet metal is a comprehensive cold processing technology for metal sheets, including shearing, punching / cutting / compounding, folding, riveting, splicing, forming, etc. Its most notable feature is that the thickness of the same part is consistent. Sheet metal has the characteristics of light weight, high strength, conductivity, low cost, good performance in large-scale mass production, etc. It has been widely used in the fields of electronics, communications, automotive industry, medical equipment, etc.

[0003] Based on the above, the inventors have discovered the following problems: during the processing of sheet metal, it is necessary to cut it into appropriate sizes. During the cutting process of the sheet metal, it is necessary to transport it through a conveying device, and then cut it during the transportation process. When this method is actually used, the sheet metal will be subjected to a large force when being cut, and there will be a large deformation or bending at the cut point, resulting in the shape of the cut point being irregular, which has certain limitations in use.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a sheet metal cutting device is provided to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a sheet metal cutting device to solve the problem that the sheet metal parts are subjected to large forces when being cut, and the cutting parts will be greatly deformed or bent, resulting in the shape of the cutting parts being irregular.

[0006] The purpose and effect of the sheet metal cutting equipment of the utility model are achieved by the following specific technical means:

[0007] A sheet metal cutting device comprises a support table, a fixing frame is arranged on the upper part of the support table, a cutting device is arranged on the fixing frame, a fixing mechanism is installed on the support table at one side of the cutting device, the fixing mechanism comprises a support plate, a through hole is opened on the support plate, a limiting rod is inserted into the inner side of the through hole, a force plate is installed at the lower end of the limiting rod, extension rods are installed at the four corners of the lower part of the force plate, the force plate is connected to a pressure plate through the extension rods, and a fixing plate is installed at the lower part of the support plate.

[0008] Furthermore, the fixing plate is connected to the support platform, there is a space between the fixing plate and the pressure plate, a first driving cylinder is installed in the middle of the support plate, and an output end of the first driving cylinder is connected to the middle of the force application plate.

[0009] Furthermore, the cutting device includes a slide rail installed on the inner side of the fixed frame, a movable plate is provided on the inner side of the fixed frame, sliders are installed on both ends of the movable plate, and the sliders are slidably connected to the slide rail.

[0010] Furthermore, a cutting piece is installed at the lower part of the movable plate, a second driving cylinder is installed on the upper part of the fixed frame, and an output end of the second driving cylinder is connected to the movable plate.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, the force plate is pushed downward by the first driving cylinder, and when the force plate moves downward, the limit rod is driven to move. The limit rod moves on the inner side of the through hole, which can ensure that the force plate moves downward more smoothly. The force plate pushes the pressure plate downward through the extension rod. When the pressure plate moves downward, force is applied to the sheet metal parts on the fixing plate to fix the sheet metal parts, thereby solving the problem that the shape of the cut part is not regular when the sheet metal parts are cut.

[0013] In the utility model, the output end of the hydraulic push rod is contracted to pull the connecting rod to move, and the connecting rod drives the bending plate to move around the movable axis. After one side of the sheet metal is fixed by the fixing plate, the bending plate lifts the other side of the sheet metal and can be bent, thereby improving the overall practicality.
