Abstract

The utility model relates to a stone cutting mould, which is composed of a mould frame, a cutter, etc. The entire mould is divided into an upper part and a lower part which are symmetrical to each other, a mould cavity is arranged and produced in the cutter, and one protective pad connected with a frame of the mould is arranged in the mould cavity. In addition, the periphery shape of the protective pad is mutually corresponding to the periphery of the cutter and the mould cavity. The included angle of two cutter faces of a cutting edge is 90 DEG. The utility model solves the problem that interlocking type constructional materials are processed in lot size, and in addition, a stone is used as a raw material of the interlocking type constructional materials. The utility model is characterized in simple and convenient procedure, high precision, assured appearance shape and size, and fully utilized raw material, and series products are produced. Simultaneously, the utility model reduces environmental pollution of dust, noise, etc., at the time of manual operation, reaches upgrading and updating of the products and improves production efficiency.

Description

The stone material shearing die

The utility model relates to a kind of machinery of stone materials processing and forming, and particularly a kind of mould of shearing stone material is particularly useful for processing interlocking type road surface product in the road administration construction material.

In the prior art, the processing of stone material be by manual cutter system or by the hand-held machinery of people cut, grinding finishes, efficient is very low on the one hand for this processing mode, its dust, noise etc. cause contaminated environment easily on the other hand, and interlocking type road surface product used in particularly building for road administration is particularly uncomfortable.

Usually, build used interlocking type road surface product, distinguish, can be divided into concrete fragment of brick and stone material from processed raw material for road administration.The typing processing of fragment of brick is generally got the concrete that will stir into and is equipped with certain color, and by after the mechanical presses moulding, process is about one month curing period, finally makes finished product by mould.Though fragment of brick can be made into the shape of interlocking arbitrarily, its quality, color and luster, compression strength etc. are low relatively.And with such as lithotomes such as granite as road administration building materials raw material, no matter be, or its quality, color and luster etc. all are the product of superior ideal from compression strength.But stone material can't carry out the machining of interlocking type product, and up to the present, the master is made or manually be cut into to the making of this series products still as above-mentioned with manual cutter.Manual product is that precision or scale all have been subjected to great limitation to producing in batches.

The purpose of this utility model is to overcome defective of the prior art, provides a kind of and can mechanically shear the stone material die device, is particularly suitable for processing the interlocking type road surface product in the road administration construction.

In order to achieve the above object, the utility model has adopted time routine scheme: in the stone material shearing die that is made of mould frame, the cutter of fixedlying connected with the mould frame etc., entire die is divided two symmetric parts up and down, the fixing riveted joint of bed die frame and guide pillar one end, this guide pillar passes the compression spring, axle sleeve on its upper end and the mold frame is slidingly connected, and forms the entire die frame.With make into a die cavity in the fixedly connected cutter of mould frame, and in this cutter die cavity, settle a neonychium that is connected with the mould frame.This neonychium is fixedlyed connected with guide blot, and by being slidingly connected with the mould frame behind the guide blot suit compression spring.The peripheral shape of neonychium is corresponding with cutter periphery and die cavity.In addition, the angle between two knife faces of cutting edge is 90 ° of right angles on the formation cutter.

Because the utility model is strong according to the stone material anti-pressure ability, the shearing die that the characteristic of shear resistance difference is made has solved the problem of the interlocking type construction material batch machining that with the stone material is raw material.Operation is easy, has improved the precision of product, guarantees the requirement of product appearance geomery.Also can make full use of big or small raw material, produce the series of products of different size.Also reduce simultaneously environmental pollutions such as dust when hand-manipulated, noise, reached the upgrading of product, improved production efficiency.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.

Fig. 1 is the utility model stone material shearing die profile;

Fig. 2 is the force analysis figure when not adding neonychium shearing stone material;

Fig. 3 is the force analysis figure that has added when neonychium is sheared stone material;

With reference to Fig. 1, entire die is divided into two parts up and down, and two parts are symmetrical up and down, and they are made of mould frame, cutter, neonychium etc.In the present embodiment, guide pillar 2 one ends and the 1 fixing riveted joint of bed die frame, and pass compression spring 3, the axle sleeve 4 on upper end and the mold frame 5 is slidingly connected, and forms a unitary mould frame that can keep cutting stroke and processing to reset.

Cutter 6 is fixedlyed connected with the mould frame by screw 7.Its cutting edge peripheral shape is according to the required corresponding shape by die-cutting cutter of shape of product that is processed into.Have in the cutter 6 one with need be processed into the corresponding die cavity 8 of shape of product.Because machined object is the fragility stone material, the toughness extreme difference, the angle that therefore forms between the cutting edge two sides adopts 90 ° of angles.And general processing has the cutter of certain toughness hard material, and the angle of its knife face is less than 90 °, why about 60 ° usually, and this is not suitable for the work brittleness stone material.Present embodiment has been selected 90 ° of right angle cuttves for use, has ensured the intensity of cutting edge.In the utility model, last bottom tool is separately fixed at up and down on the mould frame, forms relative motion during work, and machined object is two-way evenly stressed up and down, direction in a straight line, so fracture aligns mutually.

Stress is concentrated the cracky situation when shearing in order to reduce the fragility stone material, also is provided with a neonychium 11 that passes cutter 6 die cavities 8 on the mould frame, and its peripheral shape is corresponding with cutting edge roundness periphery and die cavity 8.Neonychium 11 is fixedlyed connected with the guide blot 9 of suit compression spring 10, and the other end of bolt 9 is slidingly connected with the mould frame.This neonychium 11 passes through spring 10 and guide blot 9 when work, and fluctuates according to the duty actual state, is in the position that adapts with cutter 6 and machined object.Like this, disperse the stress of machined object 12 to concentrate, increased even stressed contact-making surface, changed the phenomenon of damaged waste material in the processing effectively.

With reference to Fig. 2, when not adding neonychium 11 shearing stone materials, last bottom tool 6 stressed straight lines.Machined object 12 stress are concentrated, and are easy to generate disrepair phenomenon during production.Fig. 3 is after having set up unsteady neonychium 11 in the mould, has increased even stressed face during shearing on the machined object 12, and the situation of having disperseed stress to concentrate, its guard mode are comparatively desirable

Devices such as adoptable hydraulic pressure of power of the present utility model or punching shear mechanical are finished, and repeat no more here.
