Description

An gig apparatus of forming for manufacture of shaftless spiral screw}

The present invention relates to a molding jig device used in the apparatus for producing a spindleless spiral screw used in various transfer means.

Spindleless spiral screws are screw elements used in powder, kneading, meat processing screw conveyors, screw presses, sand separators, dehydrators and environmental waste feeders, and sewage sludge feeders.

The spindleless spiral screw forms a feeder without a spindle, and thus 90 degrees The transfer angle can be formed up to inside and outside angles, and the cover can be provided to the transfer device, which can remove odors when applied to the transfer device for chemicals or various wastes. In addition, it is possible to lower the water content of the conveyed material, thereby improving or improving the performance of the conveying device, and having the advantages of increasing the price competitiveness.

The configuration of the spindleless spiral screw has various forms depending on the intended use, but has a strip shape having a predetermined height (Sh) and thickness (St), as in the example spindleless spiral screw (S) of FIGS. 12 and 13. The thread Sp is wound in a spiral shape with a constant pitch while forming a cylindrical hole Sr having a predetermined diameter without an axis on the central axis.

Various methods and apparatuses for manufacturing the spindleless spiral screw S having the above-described configuration are provided.

One method is a method for integrally manufacturing the entire form of a spindle-free spiral screw of a predetermined size by the casting molding method, another method is two or more forming rollers are inclined at a predetermined angle with each other having a predetermined gap therebetween. The forward-molding rollers are press-fitted, and are formed to rotate in opposite directions to each other, and use a molding jig device having a configuration that rotates at a constant speed. It is a method by the material supply type | mold type | mold apparatus which manufactures by the non-spindle spiral screw which has a predetermined diameter and pitch, and press-feeds between opposing forming rollers.

Manufacturing by casting molding method among the manufacturing methods of the above spindleless spiral screw The method is useful in that the cross-sectional shape of the thread can be formed in various ways and the overall shape can be formed integrally.However, since the overall shape is formed by a fixed shape mold due to the characteristics of the casting molding, Therefore, when various shapes and specifications of threads and pitches are required, molds should be prepared for each type and specification. Therefore, when versatility is low and corrosion resistance, chemical resistance, and hygiene are required due to the characteristics of the spindleless spiral screw, In the case of gray cast iron, which is a cast molding material, the surface treatment of the screw thread should be carried out by inputting a separate process and material, and the casting process is difficult when the special molding material having corrosion resistance, chemical resistance, and hygiene is used. There is a disadvantage that the material cost is significantly higher.

On the other hand, the manufacturing method by the material supply type molding apparatus is a method of forming a spindle-free spiral screw while supplying a plate material that is calcinable to the fixed-installed molding jig apparatus by press-type, so that the length of the spindle-free spiral screw The molding jig device has a merit that the length can be arbitrarily formed, and the molding jig device can arbitrarily change the size of the molding roller and the installation interval. Therefore, the diameter, thread height, and pitch of the spindleless spiral screw can be arbitrarily specified. It has the advantage of being able to be molded into a plate, and it is possible to use a plate of special material having corrosion resistance, chemical resistance, and hygiene, which is provided with various materials of the spindleless spiral screw. There is an advantage that can be produced.

However, the manufacturing method according to the material supply molding apparatus, by pressing the sheet material that can be fired by a plurality of molding rollers by pressing the molding rollers of different phases Since it is a method of plastic molding in a predetermined non-spindle spiral thread form while going through it sequentially, the screw height and thickness of the screwless spiral screw that can be formed due to the limitation of the plastic forming force of these several forming rollers are small. It was limited to the manufacturing of a large spindle free spiral screw had a disadvantage.

The present invention is disclosed in conjunction with the present invention in order to solve the above problems, by using a belt-shaped plate material capable of plastic working as a processing material, by holding the one side end of the processing material is formed by rotation control at a constant angular speed by the drive means The molding jig device connects the shaft and the workpiece material held by the molding shaft with a constant twist angle and lead angle to rotate the molding shaft at a constant angular speed while moving the molding jig device outward along the molding shaft. Provided is a molding jig device that enables a method and apparatus for manufacturing a plastic winding-type spindleless spiral screw by a rotating molding shaft, characterized in that the screw is plastically formed by forcing a spiral into a spiral shape at an outer circumferential surface of the molding shaft. There is a purpose.
