Description

[Detailed explanation of the invention] [Industrial application field] This invention moves the piston using pressurized oil and uses a processing jig installed at the tip of the piston.
The present invention relates to a stand for a portable hydraulic processing machine that performs predetermined machining such as drilling, bending, and cutting.

[Conventional technology]

For example, at construction work sites, civil engineering work sites, etc., large numbers of reinforcing bars and steel plates are used, and mechanical processing such as bending the reinforcing bars at predetermined angles, cutting them to predetermined lengths, and drilling holes in the steel plates is performed on-site. In,
is necessary. Therefore, various portable hydraulic processing machines called benders, cutters, strainers, punchers, etc. are used.

In this type of portable hydraulic processing machine, a piston is reciprocatably disposed within a cylinder that constitutes a part of the main body. The piston head defines a pair of chambers within the cylinder on either side of the piston head. for example,
In the puncher, one chamber is in constant communication with and forms part of a reservoir, and a return spring consisting of a compression coil spring is disposed in this chamber. At the tip of the piston, there is a processing jig that corresponds to the type of processing machine, such as a punch (also called punch) for a puncher.
is attached, and a corresponding die is attached to the housing of the main body opposite the punch.

In a puncher having such a configuration, a start switch is operated after a workpiece such as an iron plate is placed between the punch at the tip of the piston and the die in the housing. Then, the built-in motor operates, and hydraulic oil (pressurized oil) pressurized by the pump is supplied from the reservoir to another chamber.
The piston moves forward against the biasing force of the return spring. Then, the punch passes through the iron plate and is fitted into the hole of the die, and a hole having approximately the same diameter as the punch is bored in the iron plate. . The chamber to which pressurized oil is supplied communicates with the reservoir via an outflow path, but the opening of the outflow path is closed by a return valve during the forward movement of the piston, that is, during the forward movement of the piston, and the chamber, Communication of the outflow path is cut off. However, when the piston moves forward by a predetermined stroke, the return valve separates from the opening of the outflow passage.
The outflow path is opened, and the chamber and the outflow path are communicated with each other.

Here, while the piston is moving forward, the return spring is compressed and sufficient biasing force is stored in the return spring. Therefore, when the outflow path is opened, the piston moves along the return path and returns to its initial position due to the biasing force of the return spring, and as the piston moves, the pressurized oil in the chamber is
It flows through the outflow channel and drains into the reservoir.

In the puncher, a manual needle valve that adjusts the amount of pressurized oil supplied is disposed between a chamber and a reservoir to which pressurized oil is supplied. Then, when this needle valve is operated to open and the pressurized oil supplied to the chamber is returned directly to the reservoir, a small hole for positioning is punched in the workpiece by the protrusion at the tip of the punch. Ru.

A known portable hydraulic processing machine is equipped with a trigger-type operating switch at the rear end of the main body and a gripping handle at the middle or end of the main body. The operator carries the hydraulic processing machine by grasping the gripping handle with one hand, and operates the operating switch with the other hand to perform predetermined machining.

Even with portable hydraulic machining machines, if the same machining process is to be repeated, the machine is fixed to a stand. In particular, portable hydraulic processing machines such as punchers and cutters are often fixed to stands.

The known stand is constructed with a stand base having a vertical support wall, and a portable hydraulic processing machine is rotatably mounted on the support wall of the stand base. Portable hydraulic processing machines are usually not vertical;
It can be attached to the support wall of the stand base while tilted backwards. Then, after positioning the workpiece in the front-rear direction by bringing the tip of the workpiece into contact with the approximately U-shaped abutment bracket attached to the main body of the portable hydraulic processing machine from behind, the operation switch is turned on. is operated to perform predetermined machining. Positioning in the front-back direction is sometimes done by eye without using an abutment bracket.

[The problem that the idea aims to solve]

On top of the die, cutter, etc. located opposite the punch, cutter, etc. processing jig at the tip of the piston,
Predetermined drilling, cutting, etc. are performed with a part of the workpiece loaded and the workpiece perpendicular to the punch and cutter at the tip of the piston.
If the workpiece is not positioned perpendicular to the processing jig such as a punch or cutter at the tip of the piston, the workpiece will easily bounce during drilling or cutting, and it will also prevent accurate processing. I can't do it.

However, the loading surface (top surface) of processing jigs such as dies and cutters on which the workpiece is placed is extremely small relative to the workpiece, and the workpiece is supported perpendicular to the processing jig at the tip of the piston. That is not easy. In particular, long workpieces are unstable and prone to tilting, and are extremely difficult to maintain accurately in an orthogonal state.

Known stands do not have any means for supporting the workpiece. Therefore, it is difficult to support the workpiece in a state perpendicular to the machining jig at the tip of the piston without tilting the workpiece, and it takes time to position the workpiece, and accurate machining cannot be performed.

The purpose of this invention is to provide a stand for a portable hydraulic processing machine that can easily support a workpiece in a state perpendicular to a processing jig at the tip of a piston.

[Summary of the idea]

In order to achieve this object, according to this invention, the stand includes an auxiliary plate in addition to the stand base.

In other words, the stand base has a vertical mounting wall and a support wall that rotatably supports the portable hydraulic processing machine, arranged in parallel. The auxiliary plate has a horizontal support surface for loading and stabilizing the workpiece of the portable hydraulic processing machine, and rotates on the mounting wall of the stand base coaxially with the rotation center of the portable hydraulic processing machine. installed as possible.

[Effect]

According to such a configuration, the workpiece is placed not only on the processing jig such as the die or the cutter, but also on the support surface of the auxiliary plate. In other words, since the workpiece is supported at two locations, the workpiece can be stably supported. Further, the support surface can be accurately moved to follow the position of the portable hydraulic processing machine, and can be accurately set to a position flush with the loading surface of processing jigs such as dies and cutters.

〔Example〕

Hereinafter, embodiments of this invention will be described in detail with reference to the drawings.

As shown in FIG. 1, a stand 10 for a portable hydraulic processing machine according to this invention includes a stand base 1
2 and an auxiliary plate 14, the auxiliary plate is composed of a main body (auxiliary plate main body) 16 and an auxiliary stabilizing plate 18.

A mounting wall 20 and a support wall 24 that rotatably supports a portable hydraulic processing machine, for example, a puncher 22, are arranged side by side on the stand base 12. In the embodiment, a pair of mounting walls 20-1 and 20-2 having the same shape as the support wall 24 are provided to be separated from each other in the front-rear direction, and the mounting wall 2 at the front (left side in the figure)
0-1 are aligned with the support wall 24. However, the mounting wall 20 may be formed from one mounting wall that is long in the front-rear direction. Further, the support wall 24 is
Usually, as shown in the figure, a pair of insertion holes 25 are provided facing each other and provided in the support wall, and are provided coaxially with the insertion hole 21-1 of the mounting wall 20-1 (see Fig. 2). reference).

As can be seen from FIGS. 2 and 3, the puncher 22 is disposed between a pair of support walls 24, and a pair of bolts 28 are inserted into the hydraulic processing machine from both left and right sides through insertion holes 25. Screwed onto the main body 23,
It is rotatably supported on the support wall. However, instead of screwing a pair of bolts from both sides, one bolt may be inserted into the puncher 22 and supported using washers and nuts, or a hydraulic processing machine may be attached to one support wall 24. May be installed. Note that a vertical elongated hole 21-2 is bored in the mounting wall 20-2.

The puncher 22, as described above,
2, it is difficult to securely fix it, and there is a risk that it may unexpectedly fall back and forth.
In particular, as shown in FIG. 3, the puncher 22 is normally tilted backward and supported by the stand 12 for ease of machining, so it is likely to fall backward unexpectedly. Therefore, the bottom 23a of the puncher body
It is preferable to interpose a height-adjustable pedestal member 30 between the stand base 12 and the stand base 12 to stably support the bottom of the main body on the stand base. The base member 30 is, for example, the bottom part 23 of the main body.
It can be formed from a bolt screwed into the screw hole 31 of a. In such a configuration, when the puncher 22 is tilted backward at a predetermined angle, the upper surface 30a of the bolt
(located at the bottom in FIG. 3), screw in the bolt so that it is pressed against the stand base 12,
Alternatively, the puncher can be attached to the stand base 12 by screwing it back. According to such a pedestal member 30 using bolts, the main body 23 of the puncher is stably supported on the stand base 12 despite the extremely simple structure, and the accidental fall of the main body can be sufficiently prevented. .

The base member 30 is attached to the bottom 23a of the main body of the puncher regardless of the change in the mounting angle of the puncher 22.
It is sufficient to stably support it on the stand base.
It is not limited to the illustrated configuration. For example, a bolt may be screwed onto the stand base 12. Alternatively, the pedestal member 30 may be constructed from a swingable support plate, and the support plate may be swung to change the support height depending on the mounting angle of the puncher 22 to support the bottom portion 23a of the main body.

The workpiece 38 itself, punched pieces produced by the puncher 22, cut pieces produced by the cutter, etc. are removed from the stand base 12.
There is a risk that the object will roll forward, scatter, and injure the operator. Therefore, the front end of the stand base 12 is bent upward, and the bent piece 1
3, and this bent piece prevents the workpiece 38, punched piece, cut piece, etc. from rolling forward.

As can be seen from Figures 1 and 3, the long hole 17-
1 is the long hole 17-2 in the insertion hole 21-1 of the mounting wall.
A pair of elongated holes 17 extend in the front-back direction so that they partially overlap the elongated holes 21-2 in the up-down direction.
-1 and 17-2 are bored in the auxiliary plate main body 16. Then, the bolt 34-1 is inserted into the insertion hole 21-
1. Another bolt 34-2 is inserted into the elongated hole 17-1 and into the elongated hole 17-2, 21-2, and fixed using a washer and a nut.

In such a configuration, the auxiliary plate main body 16 extends in the front-rear direction by an amount equivalent to the length of the long holes 17-1 and 17-2 in the front-rear direction, and extends through the long holes 21-2 in the vertical direction of the mounting wall.
It can be moved up and down by the length of . Therefore, by appropriately moving the auxiliary plate body back and forth, up and down, or by rotating the auxiliary plate body 16 around the insertion hole 21-1 of the mounting wall 20-1, the front and rear positions and inclination angle of the auxiliary plate body can be adjusted. Can be set freely. In particular, as described above, the insertion hole 25 of the support wall, which is the center of rotation of the puncher 22, and the mounting wall 2
The insertion hole 21-1 of 0-1 is coaxially formed. Therefore, the auxiliary plate main body 16, the puncher 22
The centers of rotation of the puncher are completely coincident with each other, and the auxiliary plate main body 16 can be freely rotated to various positions by accurately following the rotation of the puncher (see FIGS. 4A and 4B).

Further, as can be clearly seen from FIG. 4, a longitudinally elongated hole 17-3 is formed in the shape of a notch at the front end (left end in the figure) of the auxiliary plate main body 16.

The auxiliary stabilizing plate 18 of the auxiliary plate is constructed by welding a steel plate 36 bent into an L shape to the upper end of another steel plate 37, so that the upper surface of the horizontally positioned steel plate 36 is flat for the workpiece 38. The support surface 39 has a strong support surface. A long hole 17 in the vertical direction is formed in the vertical surface of the steel plate 36.
-4 is formed, and the bolt 34-3 is inserted into this long hole 17-4 and the long hole 17-3 of the auxiliary plate main body.
The auxiliary stabilizer plate 18 is rotatably attached to the auxiliary plate main body 16 by fixing with washers and nuts. With such a configuration, the inclination angle of the auxiliary stabilizer plate 18 with respect to the auxiliary plate main body 16 can be freely set. In addition, the elongated hole 17-4 in the up-down direction is placed in the front and rear by the length equivalent to the elongated hole 17-3 in the anteroposterior direction.
The auxiliary stabilizers 18 are moved up and down by a length equivalent to . Therefore, the degree of freedom of the auxiliary stabilizer 18 is high, the position of the support surface 39 can be selected over a wide range, and the support surface can be accurately set at the optimal position for loading the workpiece 38.

A substantially U-shaped abutment bracket 40 is attached to the main body 23 of the puncher from behind, and the workpiece 38 abuts its tip against the abutment bracket so that the loading surface of the die 44 and the two of the support surfaces 39 The punch 42 is disposed between the die and the punch 42 so as to be supported at a point.

As mentioned above, according to this invention, stand 1
0 is configured with a support surface 39 that supports a workpiece 38. Therefore, the workpiece 38 is supported not only by a processing jig such as a die cutter, but also by the support surface 39 of the auxiliary plate, so that the workpiece is supported at two locations. Therefore, the workpiece 38 can be stably and easily supported in a state perpendicular to the punch (processing jig) 42 at the tip of the piston. Therefore, predetermined machining can be performed accurately, quickly, and easily.

In particular, in the embodiment, the auxiliary plate 14 is separated into an auxiliary plate main body 16 and an auxiliary stabilizer plate 18. Since the rotational centers of the auxiliary plate main body 16 and the puncher 22 are completely aligned, the auxiliary plate main body 16 can move to various positions by accurately following the rotation of the puncher, and the loading surface of the dice 44 can be moved. The support surface 39 can be accurately set at a position flush with the surface. In this way, if the support surface 39 can be accurately set flush with the loading surface of the die 44, the workpiece 38 can be accurately supported in a state perpendicular to the processing jig at the tip of the piston.

Further, the auxiliary plate main body 16 and the auxiliary stabilizing plate 18 are not only rotatable, but also movable back and forth and up and down, giving an extremely high degree of freedom. Therefore, the supporting surface 39
is quickly and easily moved to a position flush with the loading surface of the dice 44.

Note that the auxiliary plate main body 16 and the auxiliary stabilizer plate 18 are not limited to the configurations of the embodiments, as long as they can freely move over a wide range. For example, long holes 17-2, 21-
Instead of the combination of 2, the fan-shaped hole centered on the insertion hole 21-1 is connected to the mounting wall 20-2 of the stand base,
Alternatively, it may be provided in any of the auxiliary plate main bodies 16, and the elongated hole 17-1 may be simply an insertion hole. Also,
Contrary to the embodiment, the elongated hole in the front and back direction is inserted into the auxiliary stabilizer plate 1.
8, an elongated hole in the vertical direction may be provided in the auxiliary plate main body 16. Furthermore, holes other than long holes, such as inclined long holes, may be combined. In the embodiment, a portable hydraulic processing machine is used as a puncher, but it goes without saying that the stand 10 of this invention can also be used as a stand for other portable hydraulic processing machines such as a cutter.

The above-mentioned embodiments are for illustrating this invention, and are not intended to limit this invention in any way, and any modifications, modifications, etc. made within the technical scope of this invention are also included in this invention. Needless to say.

It is set in. Further, the stand includes, in addition to the stand base, an auxiliary plate having a horizontal support surface for loading and stabilizing the workpiece. And the auxiliary board is
It is rotatably attached to the stand base coaxially with the rotation center of the portable hydraulic processing machine.

In this way, since the stand is configured with a support surface that supports the workpiece, the workpiece is supported not only by processing jigs such as dies and cutters, but also by the support surface of the auxiliary plate. , the workpiece is supported at two locations. Therefore, the workpiece can be stably and easily supported in a state perpendicular to the machining jig at the tip of the piston, and predetermined machining can be performed accurately, quickly, and easily.

With such a configuration, the positions of the auxiliary plate main body and the auxiliary stabilizer plate can be set freely, and the supporting surface can be quickly and easily set flush with the loading surface of dies and the like. The auxiliary plate body is larger than the auxiliary stabilizer plate, so it must be attached at multiple locations, usually two locations.
It is preferable to position it reliably.

In addition, if the auxiliary stabilizer is attached so that it can be rotated and moved in the front-back direction and up-down direction,
The degree of freedom of the auxiliary plate main body is increased, and the support surface can be more accurately set at a predetermined position.

The auxiliary plate can be attached to the stand base using a combination of insertion holes, vertical and longitudinal long holes, fan-shaped long holes, etc. With such a combination, the auxiliary plate can be attached to the stand base with a simple configuration. , it is possible to easily ensure a high degree of freedom of movement of the auxiliary plate.

In addition, if a height-adjustable pedestal member is interposed between the bottom of the main body of the portable hydraulic processing machine and the stand base, and the bottom of the main body is stably supported on the stand base, the main body Unexpected collapse of the roof is reliably prevented.
