Technical Field

[0001] The utility model relates to the technical field of bolt tray production, and particularly relates to a production mold for a mine bolt tray. Background Art

[0002] As an important part of the bolt support system, the performance of the bolt tray directly affects the support effect of the bolt. The function of the tray is to transmit the thrust generated by the nut locking torque to the roof and sidewalls to generate an initial anchoring force, and at the same time transmit the pressure of the roadway roof and sidewalls to the bolt to generate a working resistance, jointly reinforcing the surrounding rock and preventing the displacement of the roadway roof and sidewalls.

[0003] The commonly used bolt tray is a dish-shaped tray; the long strip steel plate, as the raw material for the production of the dish-shaped tray, is usually formed by multiple molds through cutting, pressing, and punching processes respectively; when the existing stamping mold produces the tray, the upper and lower templates squeeze the periphery of the steel plate, resulting in only partial deformation and thinning of the steel plate during the stamping process of the mold, and the formed tray has weak bearing capacity, low strength and is easy to deform, there are problems. Summary of the Utility Model

[0026] Through holes are provided on the support plate 5, and the support plate 5 is located between the upper male mold 11 and the lower female mold 4.

[0027] The working principle of the utility model is as follows: Place the steel plate to be stamped on the support plate 5, start the hydraulic cylinder 2, the piston rod of the hydraulic cylinder 2 drives the lower die 4 to press down the steel plate, and the steel plate and the support plate 5 move downward together. At the through hole on the support plate 5, the steel plate contacts the upper punch 11 through the through hole. As the piston rod of the hydraulic cylinder 2 presses down, the steel plate is pressed into a tray shape by the upper punch 11 and the lower die 4.
