Bottom punching mechanism for fire protection main unit shell

Abstract

The invention discloses a bottom punching mechanism for a fire protection main unit shell. The bottom punching mechanism comprises a rack, wherein two insertion slots are formed in the front and back sides of the top surface of the rack; a first clamping plate and a second clamping plate which are "L"-shaped and oppositely arranged are inserted into the insertion slots; a plurality of vertical discharging through slots are formed in the top surface of the rack between the two insertion slots; a punching block body is inserted into the shell to be machined; a plurality of punching heads are formed on the bottom surface of the punching block body; the punching block body is fixed on the bottom surface of a lower pressing plate; two vertical connection plates are fixed at the left and right ends of the top surface of the rack; the top ends of the connection plates are fixedly connected with a top plate; guide rods are inserted on the top plate; the lower ends of the guide rods are fixedly connected to the middle part of the top surface of the lower pressing plate; impact cams are arranged above two sides of the lower pressing plate; transmission tooth rings are formed on the arc-shaped walls, opposite to the protruded parts of the impact cams, of the impact cams; and the transmission tooth rings are connected with rotating gears in a meshing manner. The bottom punching mechanism is applicable to fixed and firm clamping of the fire protection main unit shells with different sizes, and is high in punching efficiency.

Description

[0001] Technical field: [0002] The invention relates to the technical field of fire-fighting equipment, in particular to a bottom punching mechanism of a fire-fighting host casing. [0003] Background technique: [0004] At present, the existing control host housings for fire protection need to be stamped and formed at the bottom to form ventilation holes before use. However, the existing control host housings are generally manually fixed on the frame when punching holes. , Fixing is troublesome and the effect is not ideal, resulting in errors when punching, resulting in low punching efficiency. [0005] Invention content: [0006] The purpose of the present invention is to solve the problems existing in the prior art, and to provide a bottom punching mechanism suitable for firmly clamping and fixing different sizes of fire main engine shells and having high punching efficiency. [0007] The invention relates to a bottom punching mechanism of a fire main engine shell, which...
