Description

Oscillating Molding Equipment {ORBITAL FORMING MACHINE}

The present invention relates to a rocking-molding apparatus, and more particularly, to improve the quality and durability while extending the life while preventing damage to the tool mounted on the rocking-molding apparatus to perform plastic deformation.

In general, the rock-molding apparatus is a rivet such as a rivet to prevent the detachment of the combined parts by plastically deforming the shaft end of the tubular method by inserting or combining related parts such as plastic processing (deformation) and bearings of the product by orbital motion. It is a device to make a shape.

Such rock-molding apparatus is a situation that has been developed and used in the past, a representative example of them are as follows.

An elevating means, such as a hydraulic / pneumatic cylinder or ball screw combination, a servo motor and a bevel gear combination, is provided in front of the base, and a firing means for elevating and elevating by elevating means is provided in front of the elevating means.

The firing means is composed of a motor for imparting rotational force, a main shaft rotated by the motor and a firing tool coupled to the main shaft to plastically deform an object, and the firing tool is configured to have a predetermined inclination with respect to the main shaft. The firing tool is to perform rocking molding through the orbital motion.

In the prior art configured as described above, in order to rock the molded object, the molded object is placed on the base plate provided on the base, and then, while the firing means equipped with the firing tool is rotated, the descending part is connected to the molded object by the lowering of the firing means. Afterwards, when the firing means rotates, the firing tool having a predetermined inclination with respect to the main axis performs an orbital motion to make the head portion of the shaped object into a rivet-like shape.

The firing tool is rotated by a driving force of a motor that rotates the main shaft while descending in the state mounted on the main shaft, the firing tool is mounted on the main shaft at a predetermined inclination while the bearing is intermittently rotated along the main shaft, although not at high speed. Form.

For this reason, as the bottom surface of the firing tool and the molding are connected, scratches are generated on the bottom surface of the firing tool at the moment when the molding tool is connected with the molding by the rotational force of the firing tool, and the number of times that the scratch is connected to the molding is increased. As the number increases, the surface of the molding may not be smooth due to scratching.

In addition, when a large number of scratches are generated on the lower surface of the firing tool, rocking molding is performed after replacement with a new firing tool. As a result, scratches occur at each contact with the molding, resulting in a markedly shortened life of the firing tool. It is the situation that becomes the cause.

Then, in order to prevent the occurrence of a stretch when the firing tool is in contact with the molding object, a lubricant (grease or oil) is applied to the lower surface of the firing tool. In the process of descending, it is scattered by the centrifugal force, so that only a very small amount remains in the firing tool, thereby failing to achieve the purpose of reducing scratching of the firing tool.

In particular, since the lubricant applied to the lower surface of the firing tool is scattered by the rotation of the firing tool, unnecessary waste of the lubricant is another factor, as well as the apparatus for forming the rocking apparatus as well as the peripheral device or There is a problem of polluting the equipment and the like.

When the lubricant is scattered by the rotation of the firing tool to contaminate the floor, there is a high risk of a safety accident that the pedestrian falls down due to slippage, and since a large amount of lubricant is applied from the beginning to supplement the scattered lubricant, There are many problems, such as the need to use a lot of lubricant unnecessary.

Therefore, in the present invention to solve the above problems, the frame provided with a front rest 101 for placing the molded object in front, and the upper and lower frames by the lifting means to the upper frame of the rear end frame Firing means installed to move in the direction, and the firing means is a motor for providing a rotational force, a shaft receiving the shaft drawn from the motor is coupled to the front of the elevating means, the plastic body to move up and down, and below the plastic body A main shaft connected to the shaft and having a cylindrical main shaft body, a tool body mounted to have a predetermined inclination through a bearing in the main shaft body, and a firing tool detachably connected to the tool body. In the rocking molding apparatus;

The tool is further provided with a tool clamper to prevent the firing tool from rotating with the main shaft when the firing tool is raised or lowered, and does not interfere with the operation of the firing tool when rocking.

It is possible to achieve the purpose of preventing the scattering of the lubricating material, reducing the consumption and maintaining the molding state while preventing the damage of the firing tool by prolonging the life of the firing tool in the descending process for molding.

The present invention can prevent the firing tool installed in the contraction to be rotated along the main axis to prevent the occurrence of scratches on the lower surface of the firing tool to keep the shaken molded object in a clean state while prolonging its life In addition, the invention has various effects such as greatly reducing the amount of lubricant while preventing contamination by excluding scattering of the lubricant applied to the bottom surface of the firing tool.

The general oscillation molding apparatus 100 has a frame 102 having a front support 101 for placing a molded object to be molded on the front side, and the rear frame 102 of the rear support 101 By the ordinary lifting means 103, the firing means 105 which moves in the vertical direction is provided.

The firing means 105 is provided with a motor 106 in the upper portion as a means for imparting a rotational force, and is coupled to the front of the elevating means 103 by receiving the shaft 107 drawn out from the motor 106. A rising and falling plastic body 108 is provided.

The main body 110 is connected to the shaft 107 to rotate under the plastic body 108 while pressing the object to be rotated (Orbital) and plastically deformed, and the main shaft 110 has a cylindrical shape. ), And a tool body 112 mounted to have a predetermined inclination through a bearing in the main shaft body 110 and a firing tool 113 detachably connected to the tool body 112. .

In the present invention, the firing tool 113 is prevented from rotating together with the main shaft 110 before being contacted with the molded object damage to the lower surface of the firing tool 113 and the lubricant applied to the lower surface is scattered excessively consumed It is characterized in that it further comprises a tool clamper 115 to prevent it.

The tool clamper 115 is fixed to the outer surface of the firing body 108 to project the clamper rod 116 to the lower firing tool 113 position, the lower end of the clamper rod 116 firing tool 113 Protruding in the direction to hold the firing tool 113 does not rotate during the rising or falling, while the rocking molding is connected to the preload 117 to prevent the movement of the firing tool 113.

The clumper rod 116 and the preload 117 may be formed of various materials such as plate-type, angular type, bar-type, or a variety of materials, such as metal, plastic, non-ferrous metal, and do not receive a large load Whenever possible, lightweight materials should be used.

The lower end of the clamper rod 116 has a built-in spherical motion 118 having an arbitrary direction, such as a spherical ball or spherical bearing, and a straight bearing 119 is built in the axial center of the spherical motion 118 The rear end of the preload 117 is coupled to the linear bearing 119 to allow the preload 117 to move freely regardless of the direction.

A clamp 120 for holding the firing tool 113 is obtained on the side of the preload 117, and the clamp 120 accommodates the outer diameter of the firing tool 113 to maintain a stable state in a bearing or bushing. The clamp body 122 is provided with the tool hole 121 through the structure.

Of course, on the outer surface of the clamp body 122 to arrange the interruption means such as bolts or screws to maintain a firm coupling state to prevent the plastic tool 113 and the clamp 120 is separated during the operation process. You will be fine.

Looking at the operation relationship of the tool clamper 115 of the rock-forming apparatus 100 to which the technique of the present invention is applied as described above are as follows.

The oscillation molding apparatus 100 operates by operating the motor 106 of the baking means 105 to rotate the main shaft 110, and simultaneously lifting and lowering means 103 to operate the baking means 105 in a raised state. It descends to the to-be-molded object settled by the settable 101.

As the main shaft 110 rotates as described above, the firing tool 113 is brought into contact with the shaped object, thereby plastically deforming the object through orbital movement, and the pressing force according to the descending of the firing tool 113. By rotating the baking tool 113 in an inclined state, the plastic deformation is gradually performed in a form in which only a portion joined by the inclined angle is fired without firing the molded object at once.

In this operation process, the firing tool 113 coupled to the main shaft 110 is prevented from rotating along the main shaft 110 while being lowered or raised by the tool clamper 115, thus preventing the molding of the molded object. You will not receive.

Looking at this, it is fixed to the outer surface of the plastic body 108 is coupled to the lower end of the clamper rod 116 protruding downward to the clamp 120 provided on the side of the preload 117 protruding toward the firing tool 113 direction By the firing tool 113 is in a coupled state.

Therefore, even if the main shaft 110 is lowered while rotating, the firing tool 113 is prevented from rotating along the main shaft 110, which is connected to the tool body 112 coupled to the tool body 112 through a bearing in the main shaft 110. Since the tool body 112 rotates according to the rotational force of the main shaft 110 in the coupled state 113, the main shaft 110 is rotated only by the bearing when the plastic tool 113 is held.

When the lowering is completed and the firing tool 113 is in contact with the molding object, the firing tool 113 can be naturally connected without scratching due to rotation, and the lubricant applied to the lower surface of the firing tool 113 is scattered or contaminated and wasted. You can eliminate the phenomenon.

In addition, the tool clamper 115 does not interfere with the movement of the firing tool 113 during the rocking process of the firing tool 113.

Since the preload 117 coupled with the firing tool 113 is free to move in any direction (any direction) by the spherical mover 118 coupled to the clamper rod 116, the spherical mover Since the linear bearing 119 interposed at the center of the shaft 119 freely moves in and out of the axial direction, the linear motion corresponds to the rotational diameter generated in the rotational motion.

As described above, the present invention catches the rotation of the firing tool of the rock-molding apparatus in the process of descending to prevent the damage of the firing tool, thereby prolonging its life, preventing the scattering of lubricant, reducing the consumption and improving the molding state. As well as being able to maintain, the tool does not rotate along the main axis has the advantage of being able to freely shape through the circumferential position control even in the case of a release product other than a circular.
