Description

Technical Field

[0001] The present application relates to the technical field of feeding devices, and more specifically, to an automatic feeding device for a punching machine. Background Art

[0002] Stamping is a forming processing method in which a press and a die apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. Stamping and forging belong to plastic processing (or pressure processing), collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and steel strips. Among the steel in the world, 60-70% is plate material, and most of them are made into finished products by stamping.

[0003] At present, most of the existing workpieces are stamped by manual feeding. Manual feeding and stamping are very dangerous and can easily lead to work-related accidents, making it impossible to guarantee the personal safety of workers. In addition, when placing the workpiece for stamping, the workpiece cannot be accurately placed under the stamping, which may affect the quality of the workpiece stamping.

[0004] In order to solve the above problems, the present application provides an automatic feeding device for a stamping machine. Utility Model Content

[0005] The present application provides an automatic feeding device for a punching machine using the following technical solution:

[0006] An automatic feeding device for a punching machine comprises a workbench and a punching device, an electric push rod is installed on one side of the workbench, a feeding assembly is connected to the top of the workbench, and a telescopic end of the electric push rod is connected to the feeding assembly;

[0007] The feeding assembly includes a moving seat connected to the top of the workbench, a motor is installed on the top of the moving seat, a gear is connected to the power drive end of the motor, a placing table is installed on the top of the moving seat, a first rack and a second rack are respectively connected to the bottom of the placing table, a connecting frame is installed at one end of the first rack and the second rack, a positioning plate is installed at one end of the two connecting frames, and a protective pad is provided on one side of the outside of the two positioning plates.

[0008] Through the above technical solution, the workpiece is placed on the placement table, and the workpiece is positioned in the middle of the placement table by two positioning plates, so as to facilitate subsequent accurate stamping of the workpiece.

[0009] Furthermore, two symmetrical first connecting grooves are provided on the top of the workbench, and two symmetrical first connecting plates are installed on the bottom of the movable seat.

[0010] Furthermore, the first connecting plate is located inside the first connecting groove and is a sliding connection structure.

[0011] Through the above technical solution, the movable seat is slidably connected to the top of the workbench through the provision of the first connecting plate and the first connecting groove.

[0012] Furthermore, a second connecting plate is installed on the top of each of the first rack and the second rack, and two symmetrical second connecting grooves are provided on the bottom of the placement table.

[0013] Furthermore, the second connecting plate is located inside the second connecting groove and is a sliding connection structure.

[0014] Through the above technical solution, the first rack and the second rack are slidably connected to the bottom of the placement table through the provision of the second connecting plate and the second connecting groove.

[0015] Furthermore, the punching device is located at the top of the feeding assembly, and the teeth of the gear are respectively meshed with the teeth of the first rack and the second rack.

[0016] Through the above technical solution, when the motor drives the gear to rotate, the gear drives the first rack and the second rack to rotate respectively.

[0017] Furthermore, the positioning plate is located on the top of the placement table, and the protection pad is made of rubber.

[0018] Through the above technical solution, the protective pad can protect the clamped workpiece to prevent the outer surface of the workpiece from being damaged due to excessive clamping force.

[0019] In summary, this application includes the following beneficial technical effects:

[0020] The user places the workpiece to be stamped on the top of the placement table and between the two positioning plates. At this time, the user starts the motor to clamp the protective pads set on the outside of the two connecting frames and fix the workpiece. Then, when the electric push rod is started and the feeding assembly is located directly below the stamping device, the motor drives the gear to rotate in the opposite direction, so that the two positioning plates release the workpiece, and finally the stamping device stamps the workpiece. After the stamping is completed, the electric push rod pushes the feeding assembly 3 forward, and then the next workpiece is stamped. This structure has a feeding function, which improves the safety of the stamping machine when in use. At the same time, setting the clamping function can increase the production quality of the stamping machine and avoid offset when the workpiece is placed. BRIEF DESCRIPTION OF THE DRAWINGS
