EPS foam board punching device

Abstract

The invention discloses an EPS foam board punching device, which comprises a base, a bracket is fixedly welded on the top of the base, an upper platform is fixedly welded on the top of the bracket, four hydraulic cylinders distributed in a rectangular shape are fixedly arranged on the upper platform, the lower ends of the hydraulic rods on the four hydraulic cylinders extend below the upper platform and are fixedly connected with a mounting plate; the mounting plate is provided with a pressing plate; the top of the mounting plate is fixedly welded with a fixing frame; a cylinder is fixedly arranged at the inner bottom of the fixing frame; a push plate is fixedly connected at the lower end of an air rod of the cylinder, a support rod is fixedly arranged at the bottom of the push plate, thelower end of the support rod penetrates through the mounting plate and is fixedly connected with a support plate, the outer side of the support rod is sleeved with a first spring, and the bottom of the support plate is fixedly provided with a shaft seat. The device has the advantages of stable structure, simple operation, and scientific and reasonable design, is convenient in adjusting the size and azimuth of a cut hole through replacing tools, and can save a great amount of time and effort of staff.

Description

technical field [0001] The invention relates to the technical field of EPS foam processing equipment, in particular to an EPS foam board punching equipment. Background technique [0002] Polystyrene foam is a light polymer. It uses polystyrene resin to add foaming agent, and heats to soften at the same time to generate gas to form a rigid closed-cell structure foam, which has light weight, firmness, shock absorption, low moisture absorption, easy molding and good water resistance. , heat insulation, low price and other characteristics, are widely used in packaging, heat preservation, waterproof, heat insulation, shock absorption and other fields. When using plastic foam, we usually punch a through hole in the plastic foam, and then place the item in the through hole, so that the plastic foam can protect and support the item. [0003] Nowadays, a punching machine with a drill bit is generally used to punch holes. When punching molded plastic foam, due to the expansion of th...
