Description

Vibration guide device using round leaf springs {OSCILLATOR GUIDING EQUIPMENT BY USING ROUND TYPE PLATE SPRING}

The present invention is stable vibration control and by reducing the weight burden of the mold vibrator by restraining the movement of the front and rear and left and right with the spring elasticity when the one of the playing equipment vibrating up and down by the elasticity of the spring and the vertical elastic force of the spring It relates to a vibration guide device using a round plate spring to ensure the quality of the cast.

In general, the mold vibrator used in the continuous casting equipment vibrates the mold which solidifies the molten steel up and down to prevent the break-out phenomenon of the molten steel flowing out due to sticking between the mold wall and the solidification film. It is a device for controlling the inflow of lubricant.

The breakout phenomenon can be classified into two main factors, for example, the control side causing abnormal lubrication and the abnormal vibration of the mold due to abnormality of the mechanical or hydraulic equipment for guiding the up and down vibration. It is a mechanical aspect that distorts vibration waveforms (positions and speeds) by hitting the surface or by interfering vertical movement.

However, even if the performance of the mold vibrator is superior to the performance of the controller, if there is a mechanical problem, it is essentially impossible to exhibit the original performance, and above all, a stable vibration guide device is required.

Conventionally, by installing a vibration element of the rolling element (ROLLING ELEMENT) type as shown in Figures 1 and 2A to solve the distortion of the vibration waveform caused by the irregular vertical movement, but restrained from the left and right movement during driving There was no function and the detachable structure was inconvenient to solve the above problem completely.

Further improvement of this, the flat plate spring (2) type vibration guide means shown in Figure 2b is adopted, but since the vertical displacement due to the up and down vibration assumes that the length of the leaf spring (2) is increased, the limitation on the vertical movement displacement is limited. In addition, the phenomenon of phase difference and abnormal vibration caused by forced restoring force frequently occurred, which caused the problem of not maintaining the up and down vibration stably.

In FIG. 1, reference numeral “O” denotes a mold vibrator, “3” denotes a vibration frame, “4” denotes a fixed frame, and “5” denotes a hydraulic cylinder.

The present invention has been made to solve the above-described problems, and the vertical movement range is increased by compensating the bent length that is elongated with respect to the vertical displacement by using a round leaf spring when the mold vibrates up and down. It is possible to prevent the front, rear, left and right movements, and the flexibility of the round leaf spring to solve the vertical load fluctuations and the limit of the vertical motion range, thereby eliminating the mechanical problems that can occur. The purpose of the present invention is to provide a vibration guide device using a round leaf spring to help improve productivity.

The above object of the present invention in the mold vibrator to perform a continuous casting operation by vibrating the vibration frame in the vertical direction by the hydraulic cylinder installed on both lower sides; A pair of support blocks fixed to the surfaces of the vibration frame and the fixed frame supporting the vibration frame and spaced apart from each other; A fixing pin connecting the support block; One end is fixed to the fixing pin for connecting the vibration frame side support block, the other end is fixed to the fixing pin for connecting the fixed frame side support block, a pair of first having a curved shape in a direction opposite to each other It is achieved by providing a vibration guide device using a round leaf spring, characterized in that comprising a two leaf spring.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is a side view of the round plate spring vibration guide device of the mold vibrator according to the invention, Figure 4 is a perspective view of a round leaf spring constituting the device according to the invention, Figure 5 is a front view of the device according to the invention to be.

3 to 5, a pair of "에" type support blocks 10a and b are respectively fixed to a surface where the vibration frame 3 and the fixed frame 4 face each other.

The support blocks 10a and b are connected and fixed by the fixing pin 12, and both ends of the first and second leaf springs 14 and 16 are fixed to the fixing pin 12.

The first and second leaf springs 14 and 16 form an upward or downward curved arc shape (rounded).

In particular, the first and second leaf springs 14 and 16 are preferably formed to be bent in a direction opposite to each other. For example, as shown, the first leaf spring 14 is disposed to be curved upward, and the second leaf spring is disposed. 16 are spaced downward by being spaced apart by the width of the first leaf spring 14 and staggered with each other.

In addition, only one of the first and second leaf springs 14 and 16 may be formed as a laminate, and both of the first and second leaf springs 14 and 16 may be formed as a laminate. .

As described above, forming at least one of the first and second leaf springs 14 and 16 as a stack is to increase the modulus of elasticity so as to prevent excessive vibration and to easily control fine vibration.

The operation relationship of the present invention made of such a configuration is as follows.

First, referring to the schematic diagram shown in FIG. 7, the first and second leaf springs 14 and 16 of the present invention are mounted between the fixed frame 4 and the vibration frame 3 that moves up and down. When vibration in the direction is induced, as shown in (C) of FIG. 7, the CD is moved from the initial neutral state to the CE and CF state, and as shown in (A, B) of FIG. The lengths of the first and second leaf springs 14 and 16 supported according to this change as R1 and R2.

At this time, the tensile force (P) for fixing the support blocks (10a, b) is determined by a known moment calculation formula according to the weight and dynamic state of the vibration portion.

In addition, both ends of the first and second leaf springs 14 and 16 are provided with circular clamps (not shown), and both ends of the first and second leaf springs 14 and 16 are tightened or released. The fixing pin 12 is pulled in a direction opposite to each other or pulled in a direction facing each other to adjust the upper and lower widths of the initial installation state, that is, the tension (very fine value, may be referred to as elastic modulus) do.

As described above, the first and second leaf springs 14 and 16 whose tensions are appropriately adjusted according to the type and characteristics of the steel plate are the first and second leaf springs when the vibration part of the mold moves from the neutral position to cause vertical vibration. As the bending degree of (14, 16) decreases and the length increases, the left and right fluctuations are suppressed by the elasticity and flexibility of the first and second leaf springs (14, 16) by responding to the horizontal length change with respect to the vertical movement displacement. Will be.

The above is only one preferred embodiment for describing the technical idea of the present invention, and there may be various modifications based thereon.

As described above, the present invention prevents the assembly error to prevent back and forth left and right movement when the mold vibrates up and down, thereby preventing the phenomenon of which one side is restrained in advance, and stable vibration control as well as the quality of the cast. It provides a great effect to improve and increase productivity.
