Abstract

PURPOSE:To make is possible to improve productivity and processing accuracy, by a method wherein a bladder guide covered with a bag like bladder is raised toward a drill and a desired piercing aperture is provided by drilling to the nose part of the bladde held under a fixed state by a bladder presser. CONSTITUTION:When a bladder guide 3 at a stand-by position is covered with a bag like AF bladder 4 so as to inlay the nose part thereof with a recessed part 6, it is raised by a cylinder 9 and contacted with a bladder presser 17 while the nose part 5 is fixed in a state held between the guide upper surface part 16 and a press plate 19. Subsequently, the guide 3 is further raised against a spring 22 and contacted with a drill 13 under rotation to provide a piercing aperture 26 by drilling while trashes generated during piercing are sucked from a discharge opening 12 under vacuum. In this case, the guide 3 is fallen when contacted with a stopper 23 and the bladder 4 is also fallen to be separated from the drill 13. By this method, processing productivity and processing accuracy are improved and mechanization of processing is enabled.

Description

Detailed Description of the Invention: This Genmei W air tire vulcanization and curing bladder 1 Special rolling-in-bladder tights The part corresponding to the conventional bagwell is used as a guide cylinder and is drawn into the bladder T guide cylinder together with the bladder clamp. method) middle/I) 4
This article relates to a processing device a for a bladder loaded with a vulcanizing stone for tires that can withstand 4'1ll.

Conventionally, a rolling-in-bladder-type bladder (hereinafter referred to as a tRIB bladder) for truck and bus tires equipped with 14 centers and loaded into a vulcanizer has a nose as shown in Figure 1. When penetrating into part 1, there is a problem that it is difficult to release the mold after vulcanization is completed, and molds of various sizes are required. As a measure, in factories that use a so-called autohome vulcanizer equipped with a furanyl type central mechanism, a bag-shaped bladder (hereinafter referred to as an AF bladder) loaded into the autohome vulcanizer is used. ), a vertical hole is manually made in the nose part of the R1B bladder, and the R1B bladder is machined and used. In addition, there were problems such as insufficient processing strength.

This invention was developed in order to solve the problems described above, and its main features are that it has an opening in the middle and the center, and a sho-shaped body is attached to the nuclear opening. A bladder guide supported by a bladder, a bladder presser that is biased by a spring and guides a bladder, and a bladder guide supported by a bladder.
, a stopper for applying the stopper at the n limit, and a drill supported at the center and b line of the bladder guide in close proximity to the opening of the bladder guide, and −
The bladder guide covered with the above-mentioned bladder guide is raised upwards, and a desired hole is drilled in the nose portion of the bladder which is held in place by the bladder presser. , which led to the mechanization of RIB Prada processing.
Automation has come to a standstill in the city.

This invention will be explained in detail below with reference to the drawings.

At No. 27t, the bladder guide 5 has a generally cylindrical shape as a whole, and has a recess 6 in the center thereof into which a bag-shaped bladder 40 nozzle 5 to be described later is fitted, and the inner opening 7 is It is perforated. This opening 7 is fitted with a convex body 8, and the opposite end of the concave body 8 is operated by air pressure or hydraulic pressure.
The bladder is connected to the piston rod 10 of
Guide 3 has a height of 14qJ Ng. The cylinder 9 is fixed to a machine base 11. A discharge hole 1 is provided at the other end of the hollow body 8.
2 is provided to discharge debris from the bladder nose portion 5 by a tray 13, which will be described later. By connecting this sacred ceremony &12 to the vacuum cleaner 14, it is possible to discharge one batch of waste even more efficiently. A bladder presser 17 is supported in a position corresponding to the upper surface portion 16 of the bladder guide 6 so as to be movable upward on the pool 15 erected on the base 11 . The bladder presser 17 has a presser plate 19 attached to one end of the LLI41118, and the other end is always attached in the direction of the bladder guide 3 using the locking part 2u.

The apparatus of the present invention constructed as described above operates as follows. The bag-shaped AF bladder is placed on the bladder guide 3 at the waiting position (indicated by the dotted line in Fig. 2), and the bladder guide 6 rises and comes into contact with the bladder presser (shown in the right half of Fig. 2). 1, the bladder 4 is held between the bladder guide upper surface 16 and the presser plate 19, and the nose portion 5 is fixed. (It continues to rise and comes into contact with the rotating drill 13, and a through hole 26 is drilled in the bladder nose 5, and the drill bits fall into the cylindrical body 8 and are discharged from the drain hole 12. and is collected by the vacuum cleaning mechanism 14.

As shown in the left half of FIG. 2, when the rising bladder guide 5 is stopped by the stopper 23t at its rising limit 1+1, the cylinder 9 switches to the backward operation, and the bladder guide 6 moves to the F 4 +r operation. Start. Bladder 4
Since the vnibladder 1 is firmly pressed against the bladder guide 1 and 6 by the shell 17, it descends together with the bladder guide 5, and is smoothly removed from the bird/L71'5, so that only the bladder 3 is retracted. There is no chance of being left behind. When the bladder guide 6 descends to the first position and stops, the bladder 4 is taken out from the bladder guide 3.

One cycle of f-suke ends north of this point.

As stated in the first summary, this invention is such that a bag-shaped /kF bladder is attached to a bladder guide that is supported so that it can be raised and lowered, and that it is raised and lowered relative to the drill in a fixed state to drill a through hole in the nose part. , machining productivity and machining capacity have been significantly improved,
Mechanization and automation of processing reduced the number of man hours to zero, and the technological and economic problems that were encountered in the conventional one-person molding process were eliminated, which had the great effect of solving the problem.
