Description

Rolling Machine

The present invention relates to a rolling apparatus for rolling a sheet metal material, in particular, in the interval adjusting means between the rolling rollers to determine the extrusion thickness of the rolled material, the tapered block horizontal movement adjusting means is more precise, the adjustment process is quick and The present invention relates to an extremely economical rolling device that can be easily and quickly and accurately performs a plurality of steps in a single rolling device.

In general, the rolling apparatus is a processing means for rolling a sheet material by passing the material 1 between two rollers, and the thickness of the material is gradually thinned and hardened while passing through the rollers.

Looking at the rolling process according to the prior art, for example, the manufacturing of the spoon which is one of the farming machines among the products processed using the rolling device,

In the stainless sheet-bar, which is the basic material, blanks are obtained by blanking the calculated shape to which rolling is to be rolled. Only the in bowl portion is passed between the rollers to be rolled.

In the rolling process, at least eight upper and lower roller intervals are adjusted sequentially one or more times in a single manufacturing process. The higher the thickness of the base material, the higher the thickness of the base material is required, and a multi-step process is required. Subsequent polishing processes will follow.

In this rolling and polishing process, even if the dust enters and fine scratches are processed as a defective product, in order to minimize the occurrence of defective products, it is required to prevent the occurrence of dust during the manufacturing process and to thoroughly reduce the dust collection and transfer process to a minimum.

1 is a partially omitted cross-sectional view showing the configuration of a general rolling apparatus, FIG. 2 is a side configuration diagram of FIG. 1, and FIG. 3 is a detailed view of portion A of FIG. 1.

As shown in Figures 1-3. In general, the rolling device 200 has a configuration in which a pulley 201-pinion 202-pinion driven gear 203-upper roller shaft drive gear 204-lower roller shaft drive gear 205 by the driving means 220. As a system that works with

The drive gears 204 and 205 for driving the respective shafts 206a and 207a of the upper roller 206 and the lower roller 207 are engaged with each other and rotated in opposite directions, usually vertical to the upper roller 206. It is adjusted by the roller gap adjusting means 210 for adjusting the height of the direction, wherein the upper and lower roller shafts (206a, 207a) is a power transmission in which the drive gear shafts (204a) and (205a) are moved in parallel with each other. It is coupled to the Ouldhams coupling 208 which is a coupling.

The prior art roller spacing means 210 suspends the shaft 206a of the upper roller 206 and, in particular, as shown in detail in FIG. 3, receives the elastic support 212 of the spring 214. And two tapered blocks 213 staggeredly inserted between the fixed frame 211, and the vertical distance between the variable support 212 and the fixed frame 211 is adjusted by horizontal movement of the tapered block 213. , And eventually raises or lowers the shaft 206a of the upper roller.

Reference numeral 215 denotes a half split metal bushing bearing.

The horizontal movement adjusting means of the tapered block 213 is composed of a screw 216 applied to one side of each tapered block 213, the lower tapered block 213b is determined to adjust the large range, the direct adjustment is mainly the upper As the tapered block 213a is moved horizontally, the lower variable support 212 is moved downward or upward by the elasticity of the spring 214.

The screw 216 operation of the upper tapered block 213a was set by the robot or the operator to adjust the rotation of the roller according to the process dimension of the roller gap.

Due to the setting operation of the roller gap adjusting means 210 for adjusting the roller position, in the above-described manufacturing process of the spoon, at least eight rolling apparatuses 200 are disposed, and the upper and lower rollers 206 of each rolling apparatus. (207) After setting the intervals by narrowing them in sequence according to the process, the operator is placed in each rolling device to pass the bowl surface of the roll of rolling material (1) between the rollers. The transfer process to the furnace will follow.

Even in the example of the manufacture of the spoon, the specifications are various, so the roller position must be adjusted and set according to the order from time to time, and it takes a great amount of time for skilled workers to precisely set a large number of rolling machines in accordance with the machining process. In addition, at least eight rolling devices having a scale of about 5 tons per unit should be provided, thus requiring a large work space and a large number of manpower, and a huge cost wasted in maintaining facility management. .

In addition, in the situation where the minute scratches on the surface of the material caused by the dust of the air during the rolling process require careful attention, the product is lifted and released several times as the transfer process of the product is carried out several times. In the process of changing hands, dust and product colliding are generated, and eventually it is a main cause of defective products, and there is a problem of wasting time following transportation.

The present invention has been devised to solve the above problems,

An object of the present invention is to configure the horizontal movement adjusting means of the tapered block for adjusting the position of the upper roller in the roller gap adjusting means of the rolling device, the hydraulic cylinder is a separate program and sensor according to the process Automatically controlled,

When the sequential process process consisting of at least eight times is completed, the operation of returning to the initial position by the limit switch is automatically repeated.

With only one rolling device and only one manpower, it is possible to complete a multi-stage rolling process in one place without intermediate transfer of products.

Reduces the time and manpower required to adjust the gap between the upper and lower rollers, significantly reduces the maintenance and maintenance of the work space and machine facilities of the factory and facilitates the operation of the factory. As a result of this disappearance, it is possible to provide an extremely economical rolling device that eliminates the biggest part of the factors of saving transportation time and generating defective products.
