Description

Brick pressing assembly of circular refractory brick mold

Technical Field

The utility model relates to a brick subassembly is pressed to circular refractory brick mould.

Background

The refractory material products in China have the phenomena of low labor efficiency and slow production rhythm for a long time, and are always in the labor-intensive industry, wherein the automation and high efficiency of tooling equipment are problems to be solved urgently. When a round refractory brick is produced traditionally, one or more presses are often adopted for continuous production during production, wherein the upper die is frequently assembled and disassembled due to product replacement or the reason that the upper die needs to be fired with flash and the like, but as shown in figure 1, in order to ensure the mechanical strength of equipment, the upper die of the brick pressing assembly of the traditional refractory brick die is connected into a whole by a long connecting bolt, a pressure head and a connecting steel plate which are connected with the upper die are often disassembled together in the process of assembling and disassembling the upper die, so that one or two persons are required, and the production can be completed within 1-2 hours. Meanwhile, most of the steel equipment has about 200 kilograms, so equipment such as a travelling crane and a forklift needs to be used for completion, and production is stopped for a long time.

SUMMERY OF THE UTILITY MODEL

The present invention addresses the above-mentioned problems and needs by providing a circular firebrick mold press assembly which overcomes the problems of the prior art by employing features as hereinafter described and which has other advantages as hereinafter described.

The utility model designs a following shape firebrick mould brick pressing assembly is in order to solve above-mentioned problem:

a brick pressing assembly of a round refractory brick mold comprises a connecting piece, a cylindrical pressing head and a product upper mold, wherein the cylindrical pressing head and the product upper mold are arranged below the connecting piece, and the cylindrical pressing head is connected with the connecting piece, preferably mechanically connected or integrally formed; the mechanical connection comprises a threaded connection or a snap connection. The lower side of the cylindrical pressure head is closely connected with the upper die of the product in a mode of being independently disassembled and assembled; and the cylindrical pressure head with still be equipped with stop device between the mould on the product to prevent that mould from loosening because of the vibration on the product.

Preferably, the lower side of the cylindrical pressure head is in threaded connection with the upper die of the product; the downside of cylindrical pressure head the external screw thread section and smooth section A have, mould on the product and form a mounting chamber, the inner wall top-down of mounting chamber divide into internal thread section and smooth section B, cylindrical pressure head inserts in this mounting chamber, and internal thread section and external screw thread section threaded connection.

Preferably, the product upper die is provided with a twisting piece for twisting the product upper die.

Preferably, a groove is formed on the outer side of the upper die of the product, and a torsion rod is inserted into the groove in a pluggable manner.

Preferably, when the cylindrical pressure head is connected with the upper die of the product, an anti-back nut is arranged above the upper die of the product in a manner of being tightly attached to the upper die of the product, and an anti-back gasket with a buffering effect is arranged between the anti-back nut and the upper die of the product; the anti-back nut and the anti-back gasket are screwed on the cylindrical pressure head thread section.

Preferably, a position marking line is arranged on the cylindrical pressure head, and installation completion is prompted when the die on the product is screwed to the line.

The utility model discloses a main objective is to solve the inconvenient problem of mould dismouting on the circular refractory brick mould product, and a big requirement that the brick subassembly was pressed to circular refractory brick mould is exactly whole steadiness, moreover because the part material is mostly the steel, has very big requirement to the connection reliability and the atress of subassembly, can not open whole split easily. The utility model discloses an to the analysis of part atress, adopt a scientific and reliable split type brick pressing assembly, make the product go up the mould and can regard as independent subassembly to load and unload to adopt a series of auxiliary design, make this split function effectively used.

In the optimal connection mode of the upper die and the cylindrical pressure head of the product and the design of threaded connection, the most critical point of using the screw for connection on a large-scale press is that the thread part of the screw cannot bear the force in the impact process of the press. The screw thread is processed with the well lower part of steel pressure head in this preferred design, processes out the screw thread above will going up the mould, is equivalent to make a blind nut with last mould, and the cylindrical pressure head that takes the screw thread can not the atress for large-scale screw here, screw thread side in impact process. Therefore, the bottom of the cylindrical pressure head is required to be tightly connected with the bolt surface of the upper die of the product in the design, so that stress is concentrated on the upper bottom surface of the upper die, and the threads only play a role of fixing positions; the lower part bottom segment of pressure head does not have the screw thread, revolves to twist the installation in-process like this, does not have the screw thread part can the disect insertion product and goes up the mould, has reduced the number of turns that installer need twist, and easy the accuse during the operation ensures that pressure head bottom and last mould recess internal planes are tight contact, can not have unsettledly. In order to prevent the screw from loosening caused by vibration during production, an anti-back gasket and an anti-back nut are added.

The side of the product upper die is provided with at least 1 groove, and the effect of 2 grooves is good. The purpose of forming the groove in the side face of the upper die is to insert a steel rod when the upper die of a product is rotatably mounted, so that the torsion is increased.

When the mould carries out the buckle and connects on the product, because the pressure head can cause the deformation of mould on the product when pushing down, so the buckle can face the possibility that upwards pine takes off. Therefore, the elastic material is arranged between the buckle and the buckle seat, so that the situation can be prevented.

The connecting piece and the cylindrical pressure head are mechanically connected or integrally formed. The connecting piece is preferably a connecting steel plate. Preferably, the connecting steel plate and the cylindrical pressure head can be mechanically connected by adopting a connecting bolt, and the length of the connecting bolt does not exceed the length of the cylindrical pressure head.

Compared with the prior mold assembly, the invention has the difference that originally two long bolts are used to fix the connecting steel plate, the pressure head and the upper mold (3) into a whole, and the connecting steel plate, the pressure head and the upper mold cannot be assembled and disassembled separately, so that the complexity of operation is increased. This patent adopts last mould and pressure head to use detachable type connection alone, and when the assembly, quick, effective, the production that is fit for most circular resistant firebricks can greatly improve production efficiency.
