Abstract

The utility model relates to a vibration shaper belonging to the technical field of forming mechanisms. The utility model solves the technical problems of degassing function lack, poor quality of products and low energy efficiency existing in the present vibration shaper. The vibration shaper of the utility model is provided with a pressure adjustable upper pressurization device to transfer pressure to pug through a linear spring and a dual spindle inertia exciting device to transfer vibration force to pug through a vibration transferring rod. The vibration shaper of the utility model can be especially applied to the refractory material industry and also the semifinished blank shaping in building materials industry and the ceramic industry.

Description

Vibration shaper

The utility model vibrating forming machine belongs to the forming machine technical field.

Present domestic refractory material, building materials and ceramic industry are all used the pneumatic hammer tamping tool when producing large-scale or the part with complicated structure, in the blank forming process, be easy to generate slabbing, layer density unevenness is even, and efficiency is low, noise is high, energy efficiency is low, labour intensity is big.In recent years, Anshan Iron and Steel Company's refractory factory has been developed a kind of vibrating forming machine, but exist pass the mode of shaking unreasonable, lack problem such as degassing function; Cause goods to tighten down and dredge, occur easily slabbing; Noise height, energy efficiency are low.

The purpose of this invention is to provide a kind of degassing function that has, thereby can two-sided pressurization obtain the novel vibrating make-up machine of high-quality semi-finished product base substrate.

The major technique feature of the utility model vibrating forming machine: the master cylinder (2) of an adjustable pressure is installed on four-column type frame (1), and the piston rod of master cylinder (2) is connected with spring bearer plate (3); By spring bearer plate (3) pressure of master cylinder (2) is affacted on the interior nonlinear spring (6) of spring box (7), spring box (7) is fixed on the moved cross beam (5), moved cross beam (5) can move up and down along vertically arranged guide pillar (4), cope match-plate pattern (8) be connected spring box (7) below; Under the pressure effect of master cylinder (2), cope match-plate pattern (8) can vertically enter in the model (10) and contact with pug.The motor (20) that is installed in two same sizes on the base of four-column type frame (1) passes to energy two turning cylinders (13) that symmetry and adjustable eccentric block (14) are installed on it through flexible coupling (21), turning cylinder (13) is installed in and is fixed on the following bearing block (17) of vibration table (16), and vibration table (16) is supported by the spring (18) that is installed in four rigidity unanimities on the spring base (19); The vibration-sensing rod (15) that is installed on the vibration table (16) is done the motion of vertical direction and is hit lower bolster (12), and vibrational energy is passed to the interior pug of model (10).Two model oil cylinders (9) are connected with model table (11) and finish demoulding action.Master cylinder of the present utility model (2) and two model oil cylinders (9) adopt the metallurgical equipment standard hydraulic cylinder, motor (20) adopts 7.5 kilowatts of alternating current generators, spring (18) can be steel spring, rubber spring or air spring, and other part all adopts domestic raw materials to utilize machine tool to process.

The utility model vibrating forming machine is simple and reasonable, easy and simple to handle, realized the automatic deaerating function; The production efficiency height, quality of item is good, neat appearance, go up lower density evenly, stop the slabbing phenomenon; The adaptation of product is strong, can produce all kinds of fire resistive material products, but manufacture order is great in the maximum 300kg of 40kg(), big, the complex-shaped goods of thickness; Reduce energy resource consumption, reduce labor intensity greatly, noise is low, has reached the requirement of national environmental protection.

Description of drawings: Fig. 1 is the front view of the utility model vibrating forming machine, and Fig. 2 is the side view of vibrating forming machine.

Use vibrating forming machine of the present invention and produce the embodiment of refractory material adobe: inject in the model (10) on being installed in the model table (11) that can move up and down along guide pillar (4) after the pug of constant weight, master cylinder (2) makes piston rod drive spring box (7), moved cross beam (5) and cope match-plate pattern (8) under predefined pressure and moves down; When cope match-plate pattern (8) reaches predetermined altitude H ₂When (seeing accompanying drawing 1), two motors (20) reverse rotation, vibration table (16) produces the vibration of vertical direction.At this moment cope match-plate pattern (8) does not contact with pug, and pug has increased flowability under vibrational state; Therefore pug obtains comparatively reasonably piling up, and has produced closely knit effect, and then the air in the pug is squeezed away, and this is called degasification process in the blank forming process.When cope match-plate pattern (8) continuation decline touches pug, finished degasification process.After cope match-plate pattern (8) touches pug, enter pressurization and vibration compound action process.According to by the concrete condition of the base substrate of moulding, rationally adjust the pressure F of master cylinder (2) by the fluid valve and the balancing weight of plus-minus eccentric block (14) of regulating master cylinder (2) ₁Exciting power F with vibration table (16) ₂Respectively by nonlinear spring (6) and cope match-plate pattern (8) and vibration-sensing rod (15) and lower bolster (12) pug up and down both direction apply the masterpiece that a pair of size equates substantially, phase place is opposite substantially and be used for pug, make pug obtain the effect of two-sided pressurization, be able to better closely knit.When cope match-plate pattern (8) continues to drop to H ₃The position time, base substrate has reached predetermined thickness, at this moment motor (20) shuts down; The piston rod backhaul of master cylinder (2) makes cope match-plate pattern (8) be parked in H ₁The position.Under the effect of model oil cylinder (9), connected model table (11) moves downward, and model (10) also moves down thereupon finishes demoulding action, then base substrate is taken away.

The utility model vibrating forming machine is applied to refractories industry especially, also can be applicable to the semi-finished product blank forming of building materials and ceramic industry.
