Description

Technical Field

[0001] This utility model relates to the field of stamping tooling technology, specifically a sheet metal stamping tooling. Background Technology

[0002] Sheet metal processing involves plastically deforming metal sheets through manual or die stamping to create the desired shape and size, and then further shaping them into more complex parts through welding or minimal machining. Precision sheet metal parts are thin-sheet metal components, meaning they can be processed through stamping, bending, stretching, etc. They generally refer to parts whose thickness remains constant throughout the processing. This is analogous to castings, forgings, and machined parts. For example, the outer metal shell of a car is a precision sheet metal part, as are some stainless steel cabinets.

[0003] During sheet metal stamping, the metal sheet needs to be positioned using tooling. However, in actual operation, the metal sheet is prone to extrusion deformation during positioning. Once the metal sheet is extruded and deformed, it will directly cause changes in the stamping dimensions, thus directly affecting the quality of the metal sheet. Utility Model Content

[0004] The purpose of this invention is to solve or at least alleviate the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sheet metal stamping fixture, including a base, a stamping table fixedly connected to the top outer wall of the base, a detection mechanism installed on each opposite side of the base, a drive assembly slidably installed on the opposite outer wall of the base, an opening provided on each opposite outer wall of the base, the drive assembly including two lead screws rotatably mounted on the inner wall of the opening, a drive block slidably connected to the inner wall of each of the two openings, and a common clamping seat fixedly connected between the two drive blocks.

[0006] By adopting the above structure, the base facilitates the installation of the stamping table, the detection mechanism on the base facilitates the limit detection of the metal plate on the stamping table, and the drive block in the drive assembly drives the clamping seat to clamp and fix the metal plate.

[0007] Optionally, the two drive blocks are screwed onto the outer walls of the two lead screws respectively, and two servo motors are fixedly connected to one side of the outer wall of the base, with the output shafts of the two servo motors fixedly connected to the two lead screws respectively.

[0008] By adopting the above structure, the lead screw is driven to rotate by the servo motor. When the lead screw rotates, it directly drives the drive block to move, thereby facilitating the clamping seat to clamp the metal plate.

[0009] Optionally, two mounting ports are provided on one side of the outer wall of the clamping seat, and a distance measuring sensor is fixedly connected to the inner wall of each of the two mounting ports, with the two distance measuring sensors arranged symmetrically.

[0010] By adopting the above structure, the distance measuring sensor can be easily installed through the mounting port on the clamping seat, and the distance measuring sensor can easily detect the moving distance of the clamping seat.

[0011] Optionally, the detection mechanism includes a limiting seat fixedly connected to the base, and a rectangular opening is formed on one outer wall of the limiting seat, and an adjustment component is installed on the inner wall of the rectangular opening.

[0012] By adopting the above structure, the setting of the limiting seat facilitates the installation of the adjustment component, and the setting of the limiting seat facilitates the limiting of the auxiliary metal plate.

[0013] Optionally, a contact seat is slidably connected to the inner wall of the rectangular opening, and the contact seat is connected to the adjustment assembly.

[0014] By adopting the above structure, the contact seat facilitates contact with the metal plate, and the adjustment component is triggered when the contact seat moves.

[0015] Optionally, the adjustment assembly includes a drive box fixedly connected to the inner wall of a rectangular opening, and two symmetrically arranged slide rods are fixedly connected to the inner wall of the drive box, with the same adjustment seat slidably connected to the outer walls of the two slide rods.

[0016] By adopting the above structure, the adjustment seat can be easily slidably installed by the slide rod in the drive box, thereby avoiding the offset when the adjustment seat slides.

[0017] Optionally, one end of the adjusting seat is fixedly connected to the contact seat, a pressure switch is fixedly connected to the inner wall of one side of the drive box, and the pressure switch and the adjusting seat are fixedly connected to the same spring.

[0018] By adopting the above structure, the spring is compressed by the movement of the adjusting seat, and the servo motor stops driving when the pressure switch is triggered.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] (1) This utility model sets two detection mechanisms on the base. The pressure switch in the detection mechanism facilitates the detection of the clamping force of the metal plate. When the metal plate is clamped to a certain extent, the clamping force is stopped, which effectively avoids the deformation of the metal plate when it is clamped. This solves the problem that the existing stamping fixture is prone to deformation when fixing the metal plate.

[0021] (2) By setting a driving component on the base, the screw in the driving component rotates to drive the pressing seat to move. When the pressing seat moves, it is convenient to press the metal plate on the stamping table, thereby facilitating the positioning of the metal plate and effectively preventing the metal plate from shifting during stamping.

The drive assembly 4 includes two lead screws 5 rotatably mounted on the inner wall of the opening, a drive block 6 slidably connected to the inner wall of the two openings, and a same clamping seat 8 fixedly connected between the two drive blocks 6.

[0029] By adopting the above structure, the base 1 facilitates the installation of the stamping table 2, the detection mechanism 3 on the base 1 facilitates the limit detection of the metal plate on the stamping table 2, and the drive block 6 in the drive assembly 4 drives the clamping seat 8 to clamp and fix the metal plate.

[0030] For details, please refer to Figure 1-2 Two drive blocks 6 are screwed onto the outer walls of two lead screws 5 respectively. Two servo motors 7 are fixedly connected to one side of the outer wall of the base 1, and the output shafts of the two servo motors 7 are fixedly connected to the two lead screws 5 respectively. The lead screws 5 are rotated by starting the servo motors 7. When the lead screws 5 rotate, they directly drive the drive blocks 6 to move, thereby facilitating the clamping seat 8 to clamp the metal plate.

[0031] For details, please refer to Figure 1-2 Two mounting holes are provided on one side of the outer wall of the clamping seat 8, and a distance measuring sensor 9 is fixedly connected to the inner wall of each mounting hole. The two distance measuring sensors 9 are symmetrically arranged. The distance measuring sensors 9 can be easily installed through the mounting holes on the clamping seat 8, and the distance measuring sensors 9 can easily detect the moving distance of the clamping seat 8.

[0032] For details, please refer to Figure 3-4 The detection mechanism 3 includes a limiting seat 10 fixedly connected to the base 1, and a rectangular opening is formed on one outer wall of the limiting seat 10. An adjustment component 11 is installed on the inner wall of the rectangular opening. The limiting seat 10 facilitates the installation of the adjustment component 11 and helps to limit the movement of the metal plate. A contact seat 12 is slidably connected to the inner wall of the rectangular opening, and the contact seat 12 is connected to the adjustment component 11. The contact seat 12 facilitates contact with the metal plate. When the contact seat 12 moves, it triggers the adjustment component 11. The adjustment component 11 includes a drive box 13 fixedly connected to the inner wall of the rectangular opening, and the drive box 13... Two symmetrically arranged slide rods 14 are fixedly connected to the inner wall of the drive box 13. The same adjusting seat 15 is slidably connected to the outer wall of the two slide rods 14.

[0033] Working principle: In use, the metal plate to be stamped is first placed on the stamping table 2, and then the two servo motors 7 are started. When the servo motors 7 are started, they directly drive the lead screw 5 to rotate. When the lead screw 5 rotates, it directly drives the drive block 6 to move. When the drive block 6 moves, it directly drives the clamping seat 8 to clamp the metal plate. When clamping, the metal plate squeezes the contact seat 12, which directly pushes the adjusting seat 15 to compress the spring 16. When the spring 16 is compressed, it squeezes the pressure switch 17. When the pressure reaches the set value, the pressure switch 17 is triggered. When the pressure switch 17 is triggered, the servo motor 7 stops, thus facilitating the clamping of the metal plate.
