Furniture sponge drilling machine

Abstract

The invention discloses a furniture sponge drilling machine which is good in drilling effect, convenient to use and high in working efficiency. The furniture sponge drilling machine comprises a rack, wherein the rack is provided with a workbench for placing furniture sponge, a gantry support is arranged in the middle of the workbench, a plurality of hollow drilling bits which can vertically move are horizontally arranged on the gantry support, the rotation directions of two adjacent hollow drilling bits are opposite, and a push rod which can vertically move is arranged in each hollow drilling bit. In the furniture sponge drilling machine, the plurality of hollow drilling bits which can vertically move are arranged above the workbench so as to drill a plurality of holes on the furniture sponge once, so that the working efficiency is high; and the rotation directions of two adjacent hollow drilling bits are opposite, so that the stress directions of the contact surfaces between the two adjacent hollow drilling bits and the furniture sponge are opposite, and the stress of the whole furniture sponge is in a balanced state so as to avoid deformation of the furniture sponge and ensure the drilling effect.

Description

technical field [0001] The invention relates to a drilling machine, in particular to a drilling machine for furniture sponges. Background technique [0002] At present, in the furniture industry, elastic materials such as sponges are usually built into the furniture to make the furniture more comfortable and soft. Especially in some mattresses and sofa cushions, the effect of the sponge is brought into full play. For example, there are many holes drilled in the sponge to make it more elastic, lighter in weight, and better in air permeability. Materials such as springs are built into the holes to make it elastic and increase its service life. [0003] However, in the production process, due to the soft material, inconvenient shaping and poor tensile performance, how to drill holes in the sponge quickly and easily is a huge problem. The traditional drilling method is to use a press plate with holes to compress the sponge to make it shrink, and then extend the drill bit from ...

AI Technical Summary

Problems solved by technology

Although this method can quickly drill holes and the sponge will not be torn apart by the cutting force of the drill bit, it cannot control the shrinkage direction inside the sponge after the sponge is vertically compressed. When the hole is drilled and the sponge returns to its original shape, the drilled hole The bit has been deformed, which affects its use effect
