This relates to an inner surface finishing device for finishing the inner surface of a molded member in equipment that molds and manufactures a molded member (hereinafter referred to as a molded member) into a cylindrical shape along the inner surface of a mold,
More specifically, the present invention relates to a finishing head body attached to an internal finishing device.

搬出する作用効果等が望めない。(Conventional technology) Conventionally, the internal finishing of concrete pipes, clay pipes, etc. during forming is mainly done manually (by skilled workers) using a single tool such as a brush, spatula, or trowel attached to the tip of a rod. I was finishing it. In addition, a mechanized device for finishing the inner surface of molded parts has already been published in Publication of Publication 1987-19209, but the finishing head of this device has a length that is equal to or longer than the length of the formwork in the axial direction of the tube. Since the cylindrical shape is used to hold the inner surface of the molded member in a straight line in the axial direction, it is only necessary to finish the inner surface of the molded member, and it is possible to remove surplus clay, ready-mixed concrete, etc. during molding. The separated water generated from the molded parts is scraped off from the inner surface,
It is not possible to expect the effect of exporting the product.

特徴とする。(Means for Solving the Problems) The present invention rotates the mold into which the molding material is introduced using a rotating device, so that the finishing head body A is brought into contact with the inner surface of the molding material to be centrifugally molded with a required pressure. The semicircular brush A1, semicircular round bars A2, A4, and semicircular plate A3 provided on the finished head body A when moving in the axial direction from the front opening F to the rear opening G using the slide rod 4 are molded members. The angle can be adjusted to match the radius of inner curvature of each size. Further, since the formwork 1 is rotated, the alignment angle can be adjusted by using this rotational force in a direction that allows the surplus material and separated water to be constantly carried out. Furthermore, if the formwork 1 and the formwork rotating device 2 are tilted, eccentric, misaligned, or wobbling, the finished inner surface is likely to become uneven, and when the formwork wobbles, it may separate from the inner surface or the press may be insufficient, leaving excess material and separated water. Therefore, by attaching a resilient material such as an air cylinder A6 spring or rubber to the upper part of the support shaft (inside the finishing head) and pressing it with a constant pressure, excess material and separated water can be conveyed in the axial direction and unevenness on the inner surface can be smoothed out. It is characterized by the ability to produce a smooth surface finish.

After inserting the molded member into the formwork 1, each semicircular brush A1 and semicircular round bar A are attached to the inner radius of curvature on the front side of the molded member in the formwork 1.
2. After adjusting the angle so that the outer surface of the A4 semicircular plate A3 is in contact with the entire surface, by moving the finishing head in the direction of the posterior mouth axis of the molded member, the inner surface of the molded member is automatically made redundant. A smooth surface finish is achieved while removing the material and separated water.

りも大にしておく。(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1 to 3. The finished head body A of this embodiment is produced by rotating a cylindrical mold 1 using a mold rotating device 2. When the molding material put into the mold 1 is molded into a cylindrical shape along the mold 1, surplus material on the inner surface of the molding material,
It is used for transporting separated water and for surface finishing. The finishing head body A is attached to the tip of the slide rod 4 of the internal finishing device, and is positioned by the drive motor 11 for moving the main body for horizontal movement to the formwork, the front and rear slide drive motor 6 for longitudinal movement, and the vertical slide cylinder 12 for height direction. can do. The finishing head body A is equipped with a semicircular brush A1 and a semicircular round bar A to carry out excess material and separated water and to achieve a smooth surface finish.
2.A4 and semicircular plate A3 are attached to the outside. In order to achieve a finished state suitable for other purposes (for example, a rough surface, a brushed surface, a glossy surface), the number of attached semicircular brushes A1, semicircular round bars A2 and A4, and semicircular plate A3 is changed. Alternatively, other semicircular shapes (semicircular square, hexagonal, octagonal polygonal bars, semicircular half pipes, etc.) can be attached. Inside the finishing head A, these semicircular brush A1, semicircular round bars A2 and A4, and semicircular plate A3 are attached to the outside. The inside of the finished head body A is semicircular brush A.
1. The semicircular rods A2 and A4 and the semicircular plate A3 expand and contract in the diametrical direction, so that, for example, the semicircular rod A4
An air cylinder is provided so as to operate as shown in 4' and come into contact with the inner surface of the molded member. (For the method of contacting the inner surface, an elastic body such as rubber or spring can be used in addition to an air cylinder.) Also, in order to correspond to the inner curvature radius of the square-sized molded part, it can be attached to the outside of the finishing head mentioned above. As shown in FIG. 2, a lever 10' is provided so that the angle can be adjusted in the axial direction so that the semicircular outer peripheral surface of the lever 10' is along the axis, and is connected to the angle adjustment device 10. Note that the radius of curvature of the outer periphery of the semicircular shape described above is set larger than the maximum inner diameter of each size to be molded.

After setting the contact angle of the semicircular plate A3, semicircular round bars A4, A2, and semicircular brush A1 attached to the finishing head body A with the angle adjustment device 10, contact the inner surface of the molded member with the air cylinder A6. While moving the finished head body A to the rear opening G of the inner surface of the molded member, scrape off excess material on the inner surface of the molded member and separated water generated during molding with the semicircular plate A3 and semicircular round rods A4 and A2. Transport the surplus molded parts to the inner rear port G
released to the outside. At the same time, semicircular round bars A2 and A4
gives a smooth surface finish. In addition, semicircular brush A1
Further smooth the surface and add brush marks at the same time. From the above, the above-mentioned semicircular attachment to the finished head body A of the present invention does not cause warping on the curvature inner surface of the molded member 3 by making an angle with respect to the axial direction of the molded member even if the size of the molded member is changed. can be done. Since the formwork 1 is rotating during molding, the excess material and separated water can be transported to the side using rotational force, for example.
With respect to the movement direction X of the finishing head body in the formwork rotation direction Y,
By setting an angle Q, it can be emitted. Due to the synergistic effect of the method of carrying out the scraped excess material and separated water and bringing them into contact with the curved inner surface at an angle to finish at once, the unevenness of the inner surface of the molding material is almost eliminated and a uniform and smooth finish is obtained. This is a practically effective idea.
