Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a sliding door type gate for successive victories.

The popularity of cast aluminum gates is remarkable. This is because it is possible to manufacture products that are durable, long-lasting, and have sophisticated designs without rusting or corroding.

On the other hand, the housing situation in Japan has shifted from the era of owning one's own home to single-family houses, but there is too much land available.
Because they are expensive, it is often not possible to have enough space around the house. For example, when opening and closing a gate, a space is required inside the gate to allow for a radius of rotation within the gate, but in many cases this space is not available.

In addition, in the case of land developed in a hilly area, even if there is enough space to move around the house, there are often stairs or steep slopes as soon as you enter the gate.
However, if we consider the possibility of a collision with a passerby using a gate with a radius around the inside of the gate, it is dangerous and undesirable. In fact, in some regions it is prohibited to install gates that protrude into the road.

In cases such as the above, it is natural that something like an accordion gate that can move from side to side would be convenient, and this accordion gate became an explosive seller for the entrances and exits of home garages.

However, its appearance is not enough to withstand use as an entrance gate, and it is only used as a single KV yatsuta.

This is why the development of a gate that can move from side to side and is suitable for use as an entrance gate is awaited.

As shown in Fig. 7.8, the gate of the sliding door Niun door R1, which is known from literature, is provided with a dovetail groove 0 spanning the y gold mine on the front side of the upper end part (■) of the gate body O, and on the back side of the upper end part (2). A protrusion (■) that can be secured to the dovetail groove O on the side and one end is provided. Prepare several pieces of this gate and insert the end groove of the gate (■).
Engage the protrusion O of the gate ■ with the dovetail groove of the gate 0 [Co., Ltd.]
When the protrusion ■ of the gate ■ is engaged, the gate ■
, ■, and ■ are connected one after another, and the protrusion 0 is configured to slide in the dovetail groove O in the left-right direction when opening and closing the gate.

However, it is impossible to manufacture the above-mentioned sliding door type gate using a casting method because of the dovetail grooves.

Therefore, the inventor first manufactured a C-shaped cross-section bearing shown in Fig. 6 out of stainless steel, and fixed it with screws on the top and bottom of one side of the cast gate. I looked at the method of installing a dovetail groove separately in device 1-. However, this stainless steel abutment holder did not harmonize with the cast gate, giving it a cheap feel and diminishing the solidity and luxury of the cast gate.

From the above-mentioned attempt, namely, an attempt to manufacture a protrusion holder separately and attach it to the cast gate as a dovetail groove,
One option is to directly machine a dovetail groove into the cast gate, but
This method is also not a good idea as the processing costs are too high.

Considering the various situations mentioned above, there is great significance in completing the sliding door type gate for successive victories as a cast gate. The present inventor further promoted research and finally completed the present invention.

That is, the present invention consists of the following two inventions.

(1) Extrusion of aluminum by providing on the upper surface of the frame material a groove (■) into which the molten aluminum is cast, which has a squeeze opening (■) for pouring the molten aluminum 't1'', and (2) providing a bearing fitting groove (■) on the side surface in which the bearing can run. 2 pieces of frame material for consecutive gates of desired length manufactured by pultrusion molding

While simultaneously heating the front and rear ends of the gate intermediate member O,
A method for manufacturing a gate for consecutive victories, characterized in that (1) is integrated within the frame material (■) of the gate for consecutive victories, and (2) a groove in which molten aluminum is cast.

(2) A groove (■) into which molten aluminum is cast is provided on the upper surface of the frame material, and has a squeeze opening (■) into which molten aluminum is poured.
-Bear link l11 with bearing running on the side. 2 pieces of frame material ■ for a gate for continuous use of the desired length manufactured by extrusion or pultrusion of aluminum with a large groove ■.
Prepare this, make the bearing insertion grooves ■ and ■ of the frame materials ■ and ■ of these two successive gates on the same plane, and make the grooves ■ and ■ in which molten aluminum is cast face each other, and make the front successive successive gates. Inflow grooves ■ and ■ for molten aluminum that are in contact with the consecutive gate frame materials ■ and ■ are provided at the front of the gate frame material ■ and at the rear of the consecutive victory gate frame material ■, and An inflow groove ■ for molten aluminum that forms the intermediate member ■ of the gate is provided between the frame materials ■ and 0 of the consecutive victory gate, and molten aluminum is injected from the sprue of the mold to form the front and back of the consecutive victory gate frame materials ■ and ■. While simultaneously heating the front and rear ends of the intermediate member of the gate ■ and ■
When integrating the molten aluminum in the frame materials ■ and ■ of the consecutive victory gate frame materials ■ and ■ into the grooves into which the molten aluminum is cast, the bearing insertion groove ■ of the frame materials ■ and ■ of the consecutive victory gate frame materials ■, and the open openings ■ and ■ of ■ A method for manufacturing a gate for successive victories, characterized by inserting metal rods (■, ■) along the entire length to close the openings (■, ■).

The present invention will be explained in detail below.

The frame material of the consecutive victory gate shown in Figure 3 ■ is the protruding part of the frame material with a convex end surface ■ The squeeze port into which molten aluminum is poured into the top surface ■
This is a book manufactured by extrusion 1 or pultrusion of aluminum, which has a groove ■ into which molten aluminum is cast, and a bearing fitting groove ■ in which the bearing can run on one side of the skirt [phase]. . When viewed from the end, the groove (2) into which the molten aluminum is cast has a teretabōzu shape, and its neck corresponds to the opening (2) into which the molten aluminum is cast. This molten aluminum squeeze mouth■
In this case, the cast part of the intermediate member of the gate is fitted and integrated so that there is no separation. Further, the bearing fitting groove (2) provided on one side of the skirt part (phase) has a so-called C-shaped end face, and the bearing is housed in the cavity. The four small protrusions shown in the figure are to form an intermediate part ■ in the bearing fitting groove ■, and serve as an escape route for dust that enters the bearing fitting groove ■, and prevent the bearing from running. It has been devised to make it run smoothly. Note that the groove indicated by [phase] in the figure is for receiving the flange (see Fig. 5) of the flanged bearing [phase], but it is not an essential component of the present invention, so details thereof will be omitted. The assembly of the consecutive victory gate will be explained later.

The intermediate member (■) of the cast metal gate and the frame materials (2) and (2) of the successive gate placed above and below the intermediate member are joined and integrated at the same time when the intermediate member (2) of the gate is cast. In other words, in front and behind the mold for producing the intermediate member of the gate, the bearing insertion grooves ■ and ■ of the continuous gate frame material ■ and ■ are on the same plane, and the grooves ■ and ■ into which molten aluminum is cast are placed facing each other. . At this time, the front and rear ends of the mold for producing the intermediate member (2) of the gate are continuous with the groove (2) into which the molten aluminum of the frame material of the continuous gate is cast. Therefore, the molten aluminum injected from the sprue forms the intermediate member ■ of the gate, and a portion of it also flows into the groove ■ into which the molten aluminum is cast in the frame material ■ of the connection gate, forming the intermediate member ■ of the gate. The frame materials ■ and ■ of the upper and lower interconnection gates are integrated. That is, at the same time as forming the intermediate member (2) of the gate, the intermediate member (2) of the gate and the frames (2) and (2) of the connecting gate are integrated, thereby promoting low manufacturing costs.

The intermediate member O of the above gate and the frame material of the upper and lower interconnection gate ■,
When integrating ■, an inflow groove for molten aluminum that contacts the frame material of the connection gate provided at the front side ■ of the frame material of the front connection gate and at the rear 0 of the frame material of the rear connection gate ■ ,■ plays a great role.

If there was no inflow groove for molten aluminum in contact with the frame material of the linkage gate, the frame material of the linkage gate would have been made of molten aluminum to constitute the intermediate member of the gate.
Because it is heated only from the inside, distortion occurs in the frame material of the joint gate, and as the frame material of the joint gate moves, a part of the mold breaks and deforms. Unable to make gates. Frame material for interlocking gates■,■
There are inflow grooves ■ and ■ for molten aluminum that are in contact with the
Since the frame materials (2) and (2) of the interlocking gate are simultaneously heated from both the inside and outside by the molten aluminum, no distortion occurs in the frame materials (2) and (2) of the interlocking gate.

Therefore, since the frame materials (1) and (2) of the linked gate do not move, the mold is not deformed, and a linked gate with the desired shape and dimensions can be manufactured.

In the above, even if the frame material of the joint gate is heated simultaneously from both the inside and outside of ■, the heated joint gate frame material ■,
There may be some temperature difference between the inside and outside of the door, and in such cases, some distortion may occur in the frame material of the connection gate.

Some distortions that occur in the frame materials ■ and ■ of the above-mentioned linked gates,
Pre-install the bearing insertion grooves of the frame material of the connecting gate ■ and ■.
This can be prevented by inserting metal rods (2) and (2) along the entire length of the openings (2) and (2) to close the openings. That is, if the opening (2) of the bearing insertion groove (2) of the frame material (2) of the interlocking gate is closed with a metal rod (2), the frame material of the interlocking gate will not be deformed due to thermal distortion.

In addition, FIG. 2 is an end view of a frame material for a coupling gate having a shape different from that of the frame material for a coupling gate shown in FIG. 3, and FIG. 4 is a plan view of a coupling gate obtained by implementing the present invention. It is a diagram.

Next, examples of the present invention will be described.

Example 1゜The frame material ■, ■ of the connecting gate is inserted into the bearing groove ■, ■ above and below the inflow groove ■ for molten aluminum forming the intermediate member ■ of the gate (molten aluminum is filled with molding sand to prevent the inflow of molten aluminum). ) facing upward, and facing the grooves ■ and ■ into which the molten aluminum is cast, and facing forward of the front linkage gate frame material ■ and behind the rear linkage gate frame material ■. The lower mold of the mold has the inflow grooves ■ and ■ for molten aluminum that contact the frame material ■ of the processing gate.
(not shown) to fix both molds.

Molten aluminum at 750°C is poured simultaneously through four sprues in the mold, and when molten aluminum spews out from two air vents, the pouring of molten aluminum is stopped.

Wait for the molten aluminum to cool down, separate the upper and lower molds, and take out the processing gate.

Removal 1- Unnecessary aluminum material (clumps of molten aluminum used to heat the outside of the frame ladle of the connection gate) is attached to the outside of the frame material of the connection gate. However, this is because the frame materials (2) and (2) of the connection gate are designed for a long time, so when the frame material of the connection gate is cut at a predetermined position, they separate from the frame material of the connection gate. In addition, the desired connection gate was obtained by cutting unnecessary aluminum material that had hardened in the mold runners and air vents.

Example 2 Bearing frame members ■, ■ of the connecting gate are placed above and below the inflow groove ■ for molten aluminum forming the intermediate member 0 of the gate. Fill with molding sand to prevent molten aluminum from flowing in, and then insert steel metal rods with square ends into the bearing fitting grooves ■, the open openings ■, and the entire length of ■, and fit the bearings. With the openings ■ and ■ of the grooves ■ and ■ closed, and the molten aluminum in contact with the front ■ of the frame material ■ of the front connecting section gate and the rear 0 of the frame material ■ of the rear connecting section gate. An upper mold (not shown) is placed on the lower mold (2) of the mold provided with the inflow grooves (2) and (2), and both molds are fixed.

Example 1 below. Perform the same operation as above to obtain the Renbu gate.

In addition, for molding the mold, either a green mold molding method or a molding method using vacuum force (back molding process) can be used.

Fig. 5 also shows three gates for the connected section that can be obtained by implementing the present invention.
It is a longitudinal side view of the continuous part assembled using two pieces. In the figure, [phase] indicates a bearing, and [phase] indicates a bearing with a flange. The bearing [phase] is the frame material of the gate for the upper and lower parts■
One is provided on the side of the bearing fitting groove ■ of the protruding part ■, and one is provided above the open opening ■ of the bearing fitting groove ■ on the side without the protruding part ■ of the frame material ■ of the lower connecting gate frame ■. The flange ■ is inserted into the groove @ of the frame material ■ of the gate for the connecting section of adjacent gates, and it plays the role of keeping the overlapping interval between each gate of the connecting section constant, and it is used for a long time. Prevents misalignment of overlap distance between each gate.

The method for manufacturing a connecting gate according to the present invention has the configuration as explained above, and the frame material of the connecting gate, which is the part that connects the gates, is manufactured by extrusion or pultrusion of aluminum. The processing cost of aluminum is very low when extrusion or pultrusion is used.
The overall cost can be reduced because it is about half the cost of casting. Although the frame material of the continuous gate and the intermediate member of the gate are constructed separately, their connection can be performed at the same time when manufacturing the intermediate member of the gate, so that the manufacturing cost does not increase. Frame materials for the connecting gates are placed only on the top and bottom, and no frame materials are used on the left and right sides, so there are no problems caused by metal sink marks during the casting of intermediate members, resulting in a satisfactory finish in terms of size and shape. It is an invention with high industrial applicability that exhibits excellent effects such as being able to obtain the following effects.
