Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a hole positioning device for punching, and more specifically, it is used to create a full-size paper pattern when punching multiple punching points in series on plates such as medium and thin steel plates. The present invention relates to a punching hole positioning device that can easily and accurately match each punching point in a predetermined series with the mouth portion of a plate without centering or the like.

(Prior art) Conventionally, holes in plates such as copper plates have been drilled using drilling machines, etc., which mainly perform drilling operations, in the case of thick steel plates or processing that requires precision. Since this is inefficient, most of the so-called medium-thin steel plates with a thickness of 6 m/m or more are punched using a puncher.

In this case, in order to perform accurate punching at the predetermined perforation positions on the plate, a full-size paper mold made by measuring each position from the original drawing is stretched out on the plate, or This is done by directly marking the measurements on the top surface of the plate with a chiyoke, etc., and then each worker manually moves the plate in various ways, bringing the punch of the puncher and the slotted die into matching contact with each marked position. .

(Problem that the invention attempts to solve) However, in the conventional work procedure as described above,
First, in the method of spreading out a full-size paper pattern on a plate, not only is the production of the full-size paper model itself a laborious task of measuring and marking the exact punching position on the paper pattern according to the original drawing, but also There is a problem in that it requires work to accurately spread the prepared paper pattern on the plate, and care must be taken during punching to ensure that the spread paper pattern does not shift or tear on the plate surface. .

In addition, in the method of directly writing measurement marks on the plate, the surface of the plate that will become the product will be soiled by the chalk, etc., and especially in the case of plates that will be transferred to the plating or painting process, wiping is required as an intermediate process. There is also the problem that this requires additional man-hours.

Moreover, in both of the above methods, when punching, the operator directly moves the plate in various ways.
Punching requires complicated positioning work, such as dry punching and centering at each position, including center punching, so that the punch and mouth part of the puncher come into precise contact with each marked position. Both have inefficiency problems in the previous process.

This invention was made in view of the actual situation described above, and its purpose is to solve the above problems,
It is an object of the present invention to provide a punching hole positioning device that can easily and quickly bring a punch and a slotted portion into precise contact with each predetermined series of punching points on a plate.

(Means for Solving the Problems) The features of the configuration of the present invention for achieving the above object will be explained using FIGS. 1 to 3 corresponding to the embodiments. A board 1 is mounted horizontally on a punching table surrounding the board 2 in a U shape, rack gauges 3 and 4 are laid parallel to the left and right on the board 1, and rack gauges 3 and 4 are installed perpendicularly to the gauges 3 and 4. Plate guides 5 and 6 are provided with plate guides 5 and 6 extending with the gauge reference planes A and A' facing each other in parallel with the section 2 in between, and the guides 5 and 6 are connected to the gauges 3 and 3 through pinions 7, respectively. 4, and the tip can be moved perpendicularly to the mouth part 2.
It has a piece slide base 8 which is placed close to the side and extends parallel to the guides 5 and 6 between the guides 5 and 6, and whose attachment position can be adjusted in both the front and rear and left and right directions, and the slide On the stand 8, there are a plurality of pieces 9 fixed in series at required intervals, and on the side of each piece 9, a lock is attached to the side of the piece 9 so that the locking surface B is always upright and can be retracted. The point is that a tool 10 is provided.

(Function) When using the device of the present invention having the above configuration, first fix the device so that the mouth part 2 is located directly below the punch on a ready-made punching table (not shown), and then fix the device to the dimensions of the original drawing. Therefore, in order to measure the perforation center position in the length direction of the plate P to be machined, the pieces 9 of the piece slide table 8 are slid to adjust the positions of the pieces 9. That is, first, the length from the upright locking surface B of the locking tool 10 of the first piece 9 adjacent to the mouth part 2 to the center of the mouth part 2 is determined from the center of the mouth part 2 in the length direction of the plate P. The pieces 9 are positioned and fixed so as to match the predetermined edge clearance dimensions of the frame, and each piece 9 of the series is then fixed.
Each piece 9 is fixed at a position where the locking surface B of the locking tool 10 is sequentially aligned with each perforation center of the plate P at predetermined intervals.

Next, the gauge reference plane A of the plate guide 5 is positioned at a predetermined edge clearance dimension in the width direction of the plate P from the center of the mouth part 2, and the guide 5 is fixed.
Next, the gauge reference surface of the opposing plate guide 6
A' is made to match the width of the plate P and the guide 6 is fixed.

Then, as described above, the plate guide 5 is fixed with a predetermined perforation positional relationship according to the original drawing,
6, and a locking tool that is pivoted so that the locking surface B of the top 9 is always upright and retractable when the upper plate P is placed on top of the top slide table 8 and the top 9... 10 is pressed by the plate P, and the locking tools 10 below are all in the recessed state (the plate P shown in Figures 1 and 2 is after the addition, and the plate P is shown from left to right in the figure). sent to and punched). Therefore, when starting punching, the worker grasps the starting end of plate P near the slotted part 2 and slides it on the guides 5 and 6 until the end exceeds the top surface of the slotted part 2, and the end of the plate P is below the end. The locking tool 10 of the piece 9 is the plate P
is released from the pressure of , and stands upright with its locking surface B facing upward. Here, when the plate P is pushed back a little in the direction opposite to the mouth part 2 again, the end of the plate P abuts like a latch against the locking surface B of the locking tool 10 which has been restored to the above-mentioned upright state. As a result, the plate P is automatically stopped, but at this time, the first perforation center position of the plate P is brought into exact contact with the center of the mouth part 2, and the plate P has already been stopped. It is set in a state where it can be punched.

Next, repeat the above operations one after another until the screw part 2
The locking surface B of the locking tool 10 is sequentially erected one by one by sliding the plate P over the top surface.
By simply bringing the ends of the plate P into contact with each other, the two centers of the slotted portions can be accurately brought into contact with the predetermined serial perforation centers of the plate P, and the two centers will immediately be perforated by the punch. It is.

(Example) Hereinafter, an example suitable for the apparatus of the present invention will be further described based on the drawings.

FIG. 1 is a schematic top view showing an example of a punching hole positioning device according to the present invention, FIG. 2 is a perspective view thereof, and FIG. 3 is a perspective view of a configuration related to serial hole positioning.

In these figures, P is the so-called 6m/m thick or less,
A plate such as a medium-thin steel plate, 11 is a substrate of the device of the present invention that can be horizontally mounted on the punching table of a puncher (punching machine) via a fixture, etc.
The base plate 1 has a shape that closely matches the punching table by having a U-shaped space that can enclose the center part 2 which is formed as a protuberance or fixed in the center of the punching table of the puncher, and has a frame slide table 8 fixed on the left side. It is formed with an extension part for.

Then, on the substrate 1, L-shaped cross-sections are arranged in parallel with the width interval of the punching base on both the left and right sides of the central mouse part 2, and have a length that can correspond to the width of the plate P. Rack gauges 3 and 4 are laid and fixed by screwing their feet onto the base plate 1. In addition, a rack is formed by carving a rack groove over the entire length on the upper surface of the wall portion of the rack gauges 3, 4, and a slot 2 is formed on the wall surface of the wall portion.
0 starting from the position on the horizontal extension line of the center
A gauge is formed by displaying the distance from the starting point in m/m on the left and right sides.
Further, on the rack gauges 3 and 4, there are provided a length 2 of the plate P which intersects the rack gauges 3 and 4 at right angles in front and behind the mouth part 2.
A plate guide 5 with an L-shaped cross section and double the length;
The rack gauge 3 is connected to the rack gauge 3 through a pinion 7 attached to each foot, with the plate P holding surface consisting of the wall portion and the upper surface of the foot portion facing each other, which will become the gauge reference surface. , 4 so as to be movable at right angles on the racks. In this case, the regulation of the outward movement of the plate guides 5 and 6, which are arranged in parallel to a predetermined edge clearance dimension in the width direction of the plate P and the plate width P, is restricted to the plate guides 5 and 6 in each dimension. This is done by abutting and fixing stoppers C and C' attached to the base plate 1 to correspond to the width P, respectively, on the outside of the plate guides 5 and 6.

A piece slide stand 8, which extends in parallel between the plate guides 5 and 6 with its tip in contact with the side of the mouse part 2, is mounted on the left extension part of the board 1 in both front and rear and left and right directions. It is attached so that it can be adjusted and moved. A plurality of pieces 9 are attached in series in a piece slide groove extending in the longitudinal direction parallel to the plate guides 5 and 6 provided on the piece slide table 8 so that they can be fixed at arbitrary positions with bolts or the like.

As shown in FIG. 3, the pieces 9 have a locking tool 10 formed in a ladder shape on one side parallel to the plate guides 5 and 6, which is unbalanced and pivoted on its side. , is normally suspended upright with its locking surface B facing the mouth part 2, about 10 m/m higher than the top surface of the top 9, and rotates only when pressed by the plate P from above. 9...It has a so-called retractable configuration that can be lined up at the height of the upper surface.

In this case, the upright lifting structure in which the locking device 10...the locking surface B...can be retracted is not particularly limited to the above-mentioned shape and the unbalanced pivoting structure on the side thereof, and for example, a spring or the like is used. Accordingly, a configuration may be considered in which the locking tools 10 for locking the plate P of each piece 9 are made retractable.

Here, a locking tool 10 is pivotally attached to the upper surface of the leg portion of the opposing L-shaped cross-section member serving as the plate holding surface of the plate guides 5 and 6, the upper surface of the piece 9, and the side thereof. The respective heights of the upper surfaces of the ... in the retracted state are all the same height so as to be suitable for horizontal placement, sliding, and punching of the plate P, and are all 1 to 1 higher than the height of the upper surface of the mouth part.
It is formed 2m/m lower.

In connection with the above, in advance, the plate guides 5 and 6
The lower part of the foot part and wall-like part facing the mouth part 2 is the same width as the mouth part 2, and is 1~
If you remove the height by 2m/m and form a high groove surface that can be fitted onto the groove part 2, the high groove surface can be fitted onto the top surface of the groove part 2 and the substrate on the punching table can be removed. The height positioning can be done simply by adjusting and fixing the height of 1, which is preferable.

Plate guides 5 and 6 are movably extended over the rack gauges 3 and 4 via pinions 7...
The structure may be arbitrary as long as it is capable of stably holding and sliding the plate P of each dimension width between the gauge reference planes A and A'.

(Effects of the invention) The present invention has the above-mentioned configuration, and includes left and right rack gauges placed on a board that surrounds the box part of the puncher in a U shape and is attached to the punching table;
A plate guide is orthogonal to the rack gauge and extends in parallel so as to be movable relative to each other at the front and back of the mouth part, and a piece is extended parallel to the guide with its tip touching the side of the mouth part. A slide base, and a locking device on the side surface of the slide base, which is pivoted so that the locking surface is normally upright and can be retracted and retracted, and a top that is fixed so as to be able to face each other at a required interval. Since it is a device, it can be easily assembled as a one-touch set, and it can also be easily attached to and detached from the punching table, and the height position can be easily adjusted after attachment.

When punching, in advance, based on the original drawing, the center of the slotted part is set as the zero starting point, and the gauge reference plane of the plate guide and the series locking of each piece are set in a predetermined positional relationship for each hole to be punched in series with respect to the plate. All the pre-processing is completed just by measuring and fixing each surface, so it is possible to create a full-size paper mold based on the original drawing and attach it to each plate surface, or directly write measurement marks on the top surface of the plate. All of the complicated and redundant pre-processes and intermediate processes such as wiping can be omitted.

Next, in punching in this process, the plate placed on the frame slide stand and plate guide near one side of the mouth part of the device is slid over the top surface of the mouth part, and one piece at a time is lifted upright and stopped. Since the punch can be activated simply by abutting the end of the pushed-back plate against the locking surface of the stopper, a skilled worker can directly move the plate to the puncher section for each marking position, blank punch, etc., as in the past.
The extremely inefficient and complicated positioning work of centering at each position, including center punching, is completely unnecessary, and the work time can be significantly shortened.

Moreover, since the above-mentioned complicated locating work requires no skill at all, the device can be easily imitated by inexperienced workers and enables accurate and efficient punching.
