Description

Technical Field

[0001] The utility model relates to the technical field of rail fishplate processing, in particular to a punching device for rail fishplates. Background Art

[0002] Fishtail plywood is commonly known as track plywood, also called fishtail plate, which plays a connecting role at the track joints and is divided into light rail, heavy rail and lifting rail. At present, in the processing of fishtail plywood, it is necessary to use a punching device to punch holes on its surface.

[0003] The announcement number in the existing public technology is: CN220072979U. A rail fishplate forging and punching equipment comprises a punching seat, an upper end surface of the punching seat is fixedly welded with a support seat, an upper end of the support seat is fixedly installed with a punching cylinder, the lower end of the telescopic rod of the punching cylinder is fixedly connected with a punching plate, and an upper fixing sleeve is fixedly welded on the side of the punching plate. The rail fishplate forging and punching equipment drives the punching plate to be pressed down by starting the punching cylinder, drives the support sleeve and the guide rod to move downward, and the spring generates a driving force on the pressure plate, so that the pressure plate presses the fishplate on the punching seat to prevent the fishplate from shaking when the stamping die is punched and affects the stamping accuracy. When the stamping die rises, the spring pushes the pressure plate to prevent the stamping head of the stamping die that is fastened inside the fishplate from being difficult to remove. The design of the guide rod can guide the movement of the pressure plate to prevent the pressure plate from lateral deviation and affecting the clamping and fixing of the fishplate. By turning the loose nut, the lower fixing sleeve loses its restraint, and the screw can be quickly removed to one side, which is convenient for removing the stamping die for replacement.

[0004] However, the above patent still has certain disadvantages when in use: it requires manual operation to load and unload the processed fishtail plate, which not only increases the labor intensity of the personnel, but also reduces the overall processing efficiency. Moreover, since the personnel's hands are directly below the punch, the operation risk of the personnel is increased, and the operation safety is not very good. In addition, different stamping dies need to be replaced for different punching operations, which is time-consuming and labor-intensive to operate, and the procurement cost of different stamping templates is high, which is not conducive to better use.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
