Background

When the polystyrene board material block is carved by the polystyrene board material block, in order to fix the position of the material block, the material block needs to be fixed in the X-axis and Y-axis directions of a machine table by fixed-point directional magnet adsorption and fixation in order to prevent the material block from running or deviation of the processing size caused by the cutting force of a cutter on the material block in the processing process. At present, the size of a magnetic base randomly equipped by a mainstream engraving machine is 60mm, in the process of programming a program of a processing target model by a programmer, the whole engraving can not be completed at one time due to the influence of factors such as a model structure, the size of a machine tool and the like, a mould is often divided into 2-3 layers, sometimes, the lowest point of a cutter is lower than 60mm when the engraving machine runs the program, the phenomenon that the cutter collides the magnetic base during processing is easy to occur, and the damage to the cutter and a main shaft of the machine tool is caused. Or the magnetic base directly clamps the model body to cause pit defects, local stress is overlarge and no buffer area exists, so that unrepairable impressions (namely plastic deformation) of the model body are caused, and the subsequent model making and repairing are needed for the damaged model appearance. These problems increase production costs and reduce production efficiency, which has always plagued the model engraving industry.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

A magnetic base crash cushion for use in pollon carving, as shown in fig. 1, the apparatus comprising: 60 x 60mm polystyrene board 1 and two-liquid mixed hardened glue, the 60 x 60mm polystyrene board 1 is composed of expandable polystyrene beads containing volatile liquid foaming agent, and is heated and pre-expanded in a mold to be molded into white solid with a fine closed pore structure. The foam in the form of the shockproof foam in the buyer's utensil is the same as or similar to the model component. The 60 x 60mm polyethylene polystyrene board 1 is made by cutting a polyethylene polystyrene board material block at a high speed by a fine-tooth saw blade through a fine-bar electric band saw machine, and has the same or similar size with the magnetic base.

As shown in fig. 4, the 60 × 60 × 60mm polyvinyl benzene boards 1 are symmetrically arranged around the model body 3 to be processed, in this embodiment, the number of the 60 × 60 × 60mm polyvinyl benzene boards 1 is 8, two 60 × 60 × 60mm polyvinyl benzene boards 1 are arranged on each edge of the periphery of the model body 3 to be processed, and the contact surfaces of the 60 × 60 × 60mm polyvinyl benzene boards 1 and the model body 3 to be processed are seamlessly cemented by two-liquid mixed hardened glue; the two liquids are mixed to harden the glue, one liquid is the glue, the other liquid is the hardening agent, the two liquids can be hardened after mixing, and the glue can be hardened without depending on the temperature, so the glue is one of the normal temperature hardening glue, after mixing, the glue can be dried up in 5 minutes at 25 ℃, and the drying time is shorter when the temperature is higher. The epoxy resin adhesive has the advantages of high bonding strength, high hardness, high chemical resistance and yellowing resistance of common epoxy resin adhesives.
