Description

Roller Support Forming Equipment {An upholding part making apparatus for the roller}

The present invention relates to a molding apparatus for manufacturing a roller having a light weight, which is hollow inside, and in particular, a roller mold is installed in a work block provided to be capable of rotating and linear movement, thereby frictionally rotating at an end of the roller body fixedly rotatable. When the end of the roller main body is formed by a step of forming a relatively small diameter step by the frictional heat is related to a roller support forming apparatus for forming a support.

A general roller is formed in various shapes and sizes and installed in various devices. For example, a roller is used as one of a heating device and a conveying device installed in an output device such as a copying machine or a printer. When the heat wire is disposed inside the hollow to form a heat roller, and when disposed to correspond to the heat roller, a pressure roller is formed.

As a result, pressure and heat are supplied while the workpiece passes between the heat roller and the pressure roller, thereby compressing the printed contents applied to the outer surface of the workpiece.

Looking at the example of applying the roller as described above to the copier as follows. First, the copier scans the light of the light source into the photosensitive drum as a shaped image, and the toner, which acts as an ink only, is applied to the photosensitive drum portion where the light is injected. When passing through the lower part, the toner on the photosensitive drum is attached to the paper to form an image and discharged.

At this time, the paper on which the toner is soaked is discharged in a completely fixed state while passing between the heat roller and the pressure roller which are pressurized with high temperature heat to completely fix the toner on the paper. In this way, the copy is made.

Here, the roller is a step is formed in both ends of the diameter of the pipe becomes smaller, the bearing is installed in each step, the size of the bearing can be reduced by this step to reduce the unit cost of the printer and copier in which the roller is installed Can be lowered, and the bearings thus installed allow the roller to be rotatably supported inside the copier or the printing press.

However, the roller according to the prior art is stepped because a step is formed by a spinning or swaging operation such that the diameter of the pipe end is reduced while the roller die in contact with the circumferential surface of the pipe being reciprocated from the end of the pipe toward the center. Since the support is formed to form a step that is gently bent, the bearing is installed on the support to be rotatably mounted in the copier or printer, there is a problem that the bearing can not be seated in the correct position.

In addition, the roller according to the prior art processes the support part separately so that the step forming the support part is bent at a right angle, and the support parts are fused to the both ends of the pipe by argon welding or the like, which is a large number of rollers. It is made by a sequence of processes, and because the equipment and adhesive required for the adhesion is required, there is a problem that the unit cost of the product on which the roller is installed can not be lowered below a certain value.

The present invention is devised to solve the above problems of the prior art, by contacting from the end of the roller body that is rotated at a high speed is moved by the roller mold to be horizontally moved to the inside of the roller is formed by bending, It is an object of the present invention to provide a roller support part molding apparatus capable of molding a step having an angle at right angles by one step.

In this case, the spindle 44 is arranged such that the rotation axis thereof is parallel to the rotation axis of the roller body 52, so that a step is formed in a portion where the upper end of the spindle 44 contacts the peripheral surface of the roller body 52. After the working block 20 is moved downward along the first rail 32 so that the roller die is positioned on an extension line of the rotation axis of the roller body 52, the second rail 34 is moved. Accordingly, when the working block and the first rail are slid toward the roller body side, the upper end of the spindle 44 of the roller mold starts to contact the end of the rotating roller body, and the step is gradually stepped on the roller body while being moved to the inside of the roller body. The final step is formed so that its bending angle is 90 °.

Of course, when the working block 20 slides a predetermined amount upward along the first rail 32 when the working block 20 is moved along the second rail 34 to the roller body side, the bent portion is 90 ° or less. It is also possible to shape the step forming the inclined surface of the.

In addition, at least two spindles 44 may be installed, and the number of the spindles 44 may be variously determined according to the size of the roller body 52. When the rollers are made of steel, the spindles 44 are driven by the spindles 44. Since the means is installed so that its own rotational force can be generated to improve the processing efficiency, if the material of the roller is a non-ferrous metal of relatively low strength, such as aluminum alloy, the roller body 52 is rotated, and installed idling The spindle 44 is contacted so that the roller body 52 is bent by the heat and pressure generated by the friction to form the support 54.

In addition, two roller molds 40 are provided as the first roller mold 40a and the second roller mold 40b in the present invention, which are used to process the support part 54 on the roller body 52. By forming the support part 54 of the diameter desired by a user finally after the 1st operation | movement which forms a predetermined amount step | step, it is for preventing the excessive shear stress generate | occur | produced in the roller main body 52.
