Abstract

The utility model discloses a sand blasting die block. A hard board is provided with a hollow cavity which conforms to the pattern form of the workpiece surface. As the hard board is used as the sand blasting die block, the same pattern of the sand blasting die block can be repeatedly used in bulk production on a plurality of workpieces. When the steel plate or the cast iron plate is used as the hard plate to produce the sand blasting die block, the die block is adhered to the workpiece surface. The back surface of the workpiece uses the electromagnet to attract the die block made of the hard plate and causes the die block to be fixed. The complicated adhering and thin film taking off are not needed. The fixation and the handling are convenient. The hollow pattern is made on the hard plate, the fine part can be presented, and the visual effect is beautiful and lifelike. The sand blasting die block is easily stored and has non-perishable deformation. The processing workpiece of the die block has convenient construction. The bulk production of the sand blasting product has high work efficiency and low cost, and is adapted for being used on the automatic sand blasting machine.

Description

The sandblast template

Technical field

The utility model belongs to instrument, and specifically a kind of smooth surface to workpiece carries out the template that blasting treatment is used.

Background technology

Existingly will process floral designs on the smooth surface of glass, marble etc., when being used for doing handicraft or doing product such as home decoration door and window, table top, generally be that the way with blasting treatment solves on the said goods.Its concrete operations are; abatement processes at first dewaters the surface of workpiece to be machined; to be carved with pattern and again wears the diaphragm of viscose glue and is attached to securely and handles on the clean surface; start the sand-blasting machine sandblast; when treating to occur on the surface of the work pierced pattern on the diaphragm, diaphragm is all taken off.Use diaphragm to be attached to the surface of the work blasting treatment following many drawbacks arranged:

At first, when taking off diaphragm, can not stay viscose glue and vestige on the product, can not stay stain on the patterned surfaces of ejection, to keep the bright and clean and attractive in appearance of product, do so time-consuming and very difficult, inefficiency;

On the other hand, the diaphragm of needle drawing case there is strict requirement, the one, claimed film has enough intensity, and the impulsive force of the diamond dust that sand-blasting machine sprays reaches the 6-8 kilogram, and undercapacity will puncture diaphragm is destroyed pattern; Even so, even if diaphragm has enough intensity, because diaphragm is too thin, depiction on diaphragm, its trickle part also is difficult to display after blasting treatment, and for the diaphragm that large area pattern is arranged, its operation easier is bigger;

Moreover the viscosity of viscose glue is wanted suitably can stick to protected surface of the work securely on the diaphragm, can take off smoothly again to leave no trace after sandblast; Also have, diaphragm is disposable use, even if spray identical pattern, every workpiece also will have diaphragm separately, uses the amount of diaphragm very big;

Also have, diaphragm is subjected to the influence of extraneous factors such as temperature, humidity very big, must deposit in strict accordance with requiring, and just can reach instructions for use.

The utility model content

Technical problem to be solved in the utility model is; when overcoming prior art and using patterned diaphragm to be attached to the surface of the work sandblast time-consuming work efficiency low, easily punctured by sandblast and destroy pattern; the trickle part of pattern is difficult to manifest and the quality of diaphragm is subjected to shortcomings such as ectocine is big, provides the pattern of a kind of work efficiency height, ejection indeformable, sprays with the repeatedly used sandblast template of a kind of pattern.

In order to solve the problems referred to above that prior art exists, the technical solution of the utility model is: the sandblast template is to be provided with the hollow out cavity consistent with the surface of the work pattern form on hardboard.

The utility model also has following key character:

The positive and negative two sides of hardboard in band hollow out cavity all is bright and clean plane.

During use, it is fixing that template is attached to workpiece to be machined surface, template and the workpiece that is fixed together with it is placed on below the nozzle of sand-blasting machine, starts sand-blasting machine, the diamond dust of ejection drops on the openwork part of template, surface of the work will stay with template on the same pattern that designs.

Advantage of the present utility model and good effect are: because the sandblast template is to make with hardboard, can use repeatedly on a kind of a plurality of workpiece of pattern; When making the sandblast template as hardboard with steel plate or cast iron plate, template is attached to surface of the work, can it be fixed in the template that make with the attraction hardboard at the back side of workpiece.When the positive and negative two sides of hardboard all was bright and clean plane, magnet attracted to fix better to hardboard, did not need complicated sticking film and took film off, and is fixing, easy to loading and unloading; Make pierced pattern on hardboard, its trickle part all can display, its visual effect fineness, true to nature; Template is taken care of well, and is not yielding.Use the easy construction of above-mentioned sandblast template processing work, produce sandblast product work efficiency height in batches, cost is low, is very suitable for using on automatic sand-blasting machine.

Description of drawings

Fig. 1 is a front view of the present utility model;

Fig. 2 is the rearview of Fig. 1;

Fig. 3 is attached to the fixing side view of surface of the work for template among Fig. 1.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Among Fig. 1, the sandblast template is on the hardboard made from gravity die sheet material 1, and the cavity 2 (referring to Fig. 2) according to the pattern of design is made hollow out is attached to workpiece 5 surfaces with hardboard 1 and goes up fixing (referring to Fig. 3).During sandblast, cavity 2 parts on the hardboard 1 are formed frosting by the scrap emery hacking of high pressure, and the yoke plate 3 beyond the cavity 2 has stopped the diamond dust of sand-blasting machine ejection, the surperficial protected or original smooth surface of this part workpiece.

The pattern cavity 2 of described hollow out can be to form with the engraving cutting.

Hardboard 1 can be the metallic plate or the plastic plate of hardness height, anti-sandblast impulsive force, can make of steel plate or cast iron plate but preferably use.

Among Fig. 3, when making the sandblast template as hardboard 1 with steel plate or cast iron plate, template is attached to workpiece 5 surfaces to be gone up fixing, can adopt the template that attracts hardboard 1 to make with magnet 4 at the back side of workpiece 5, hardboard 1 its positive and negative two sides 1.1,1.2 in band hollow out cavity 2 all is bright and clean plane, be beneficial to the hardboard 1 that 4 pairs of magnet are attached on the workpiece 5 and attract more firmly, install and fix during blasting treatment workpiece 5 convenient, fast like this.

Described hardboard 1 profile of doing the sandblast template can be a square, can be circular, can also be semicircle, or other outer contour shapes identical with workpiece 5.

The utility model is particularly suitable for sandblast use on automatic sand-blasting machine.

Claims

1, a kind of sandblast template comprises hardboard, it is characterized in that: be provided with the hollow out cavity consistent with the surface of the work pattern form on hardboard.

2, sandblast template as claimed in claim 1 is characterized in that: be with the positive and negative two sides of hardboard in hollow out cavity, be fixed in the bright and clean plane of surface of the work for available attraction.
