Floor drain punching device for water heating hardware

Abstract

The invention belongs to the technical field of hardware machining, and particularly relates to a floor drain punching device for water heating hardware. The floor drain punching device aims at the problem that in the prior art, according to a punching mechanism for a floor drain, the quality of the floor drain is likely to be reduced, and the service life of a punching part can be shortened. According to the following scheme, the floor drain punching device comprises a fixed seat, a mounting base connected with a hydraulic lifting mechanism is arranged at the top of the fixed seat, and multiple punching parts are fixed to the bottom of the mounting base; punching grooves matched with the punching parts are formed in the top of the fixed seat, clamping grooves are formed in the top of thefixed seat, and the punching grooves are formed in the bottom inner wall of the clamping grooves; and auxiliary grooves of annular structures are formed in the outer walls of the punching parts. According to the floor drain punching device, in the process that the punching parts are pressed downwards for punching holes and lifted, a grinding block collides with the edge positions of punched holesin a substrate to grind away burrs at the edge positions, burr chippings fall into the punching grooves directly or along the auxiliary grooves, and therefore abrasion to the punching parts and the influence on the quality of a finished floor drain are avoided.

Description

technical field [0001] The invention relates to the technical field of hardware processing, in particular to a floor drain punching device for plumbing hardware. Background technique [0002] Plumbing hardware refers to the general term for hardware used in building water supply and drainage systems, heating systems and toilets, usually including faucets, showers, valves, pipe connectors and other hardware in toilets. Hardware processing is to use lathes and milling machines for raw materials , drilling machine, polishing and other machinery are processed into various parts according to the customer's drawings or samples. Floor drains are a common type of plumbing hardware. During the process of floor drain processing, it is often necessary to punch holes on the surface of the substrate. [0003] Nowadays, in the process of punching the floor drain, the substrate material of the floor drain is generally fixed above the punching mechanism, and a plurality of fixedly arranged ...

Problems solved by technology

[0003] Nowadays, in the process of punching the floor drain, the substrate material of the floor drain is generally fixed above the punching mechanism, and a plurality of fixedly arranged stamping parts are pressed down by a hydraulic mechanism to punch out corresponding slots on the surface of the substrate. However, during the actual punching operation, there will be burrs on the edge of the punched slot hole on the substrate, which will cause wear to the outer wall of the stamping part, or the stamping part will cause wear to the inner wall of the slot hole, which will easily reduce the quality of the finished floor drain And will reduce the service life of stamping parts
