Abstract

PROBLEM TO BE SOLVED: To provide an apparatus for processing such as piercing or die stamping having simple structure which prevents an erroneous rotational movement in a plan view angle θ direction and supports stably a plunger so as to be capable of moving up and down. SOLUTION: A pair of ball bearings 8, 8 which is able to be adjusted in the eccentric direction, clamps a slide guide 34 projected forward from a moving lock 4 which connects loosely a hammer portion 121 with the plunger 3 having a punch 5 with a cross-sectional shape except perfect circle at low portion, and appropriate clamping force needed for sliding is acquired by adjusting the eccentricity of the pair of ball bearings 8, 8. Furthermore a guide plate 6 is allowed to move a little in the right and left linear direction and the plunger 3 is caused to rotate a little around the slide guide 34 clamped with a pair of the ball bearings 8, 8, thereby finely adjusting the plan view angle θdirection of the punch 5.

As shown in FIG. 7, a single-shaft punching device and a single-shaft type pressing device are provided with a driving force source provided on the upper half portion 11 of the processing unit 1 having a U-shape in a side view. The hammer portion 121 at the lower end of the plunger 3 having a processed portion (not shown) at the lower end and the upper end of the plunger 3 having the machined portion (not shown) at the lower end are moved together with the movable block 4 in a state where the hammer portion 121 and the plunger 3 abut. They are connected by a so-called connecting tool. The mu-lock 4 has a bifurcated portion 14 for sandwiching a small-diameter root portion of the hammer portion 121 having a large-diameter portion at a lower end portion.
A horizontal portion 24 having an insertion hole 241 into which the upper end of the plunger 3 is inserted, and a slidable portion 44 extending further from the horizontal portion 24 toward the upper half portion 11 of the processing unit. is there. The connection between the hammer portion 121 and the plunger 3 is made by a small screw 60 screwed into the horizontal portion 24 at the upper end of the plunger 3 fitted into the insertion hole 241.
0 The front end is pressed from the side to be fixed, and the sliding portion 44
The sliding portion 44 is guided by a pair of ball bearings 8 ', 8' provided on the front surface of the upper end of the upper half portion 11 of the processing unit. Then, the driving force of the driving source is transmitted to the plunger 3 via the hammer 121, and the slidable portion 44 is guided up and down by the pair of ball bearings 8 ', 8' so that the processing portion is formed. It is designed to pierce and emboss. However, if the pair of ball bearings 8 ′, 8 ′ loosely sandwiches the slidable portion 44, the processed portion having a cross-sectional shape other than a perfect circle is formed in the θ direction in plan view. If it is finely rotated, it leads to a processing error, and if it is tight, the sliding resistance of the slidable portion 44 increases, and the ball bearings 8 ′, 8 ′ and the slidable portion 44 It is necessary to generate rattling due to abrasion, and the assembling work for mounting the pair of ball bearings 8 ', 8' with high precision so as to clamp the sliding portion 44 with an appropriate clamping force is also very difficult. It was troublesome. In addition, the forming of a processed portion (punch, press die, etc.) from a round bar is difficult to center out, requires a special jig, and is difficult to process.

According to the above technical means, when the driving source for driving the hammer is driven, the driving power of the hammer is transmitted to the processing part via the plunger, and the work is processed. At this time, the slidable portion provided on the mook lock slides up and down while being sandwiched between a pair of ball bearings using the vertically long hole of the guide plate provided on the front surface of the processing unit as a guide. And, a sliding part protruding forward from a mook block connecting the hammer part and a plunger having a processing part in a lower part so as to be able to be inserted and removed is sandwiched by a pair of ball bearings,
Since the holding surfaces (left and right side surfaces) of the sliding portion are convexly curved, an appropriate clamping force required for sliding the sliding portion can be provided by adjusting the eccentric direction of the pair of ball bearings. . A guide plate having a vertically long hole for mounting the pair of ball bearings and guiding the slidable portion so as to be able to move up and down is provided on the front surface of the machining unit so as to be linearly movable in the left-right direction. Since the left and right sides of the convex curved surface of the moving part are pinched by a pair of ball bearings in a line contact manner, when the guide plate is moved slightly linearly in the left-right direction, the guide plate is pinched by a pair of ball bearings in a line contact state. The plunger is finely rotated together with the move lock with the slidable portion as a fulcrum, and the orientation of the processed portion in the θ direction in plan view is finely adjusted.

As described above, the present invention is constructed as described above, and is directed forward from a mook block for removably connecting a hammer portion and a plunger having a punch having a cross section other than a perfect circle below. The slidable portion protruded from the slidable portion is sandwiched between a pair of ball bearings, which can be adjusted in eccentric direction, provided in a guide plate having a vertically long hole for guiding the slidable portion, and is slid up and down. In addition, the slidable portion of the mu-lock that descends during the driving of the striking can be slid by adjusting the eccentric direction of the pair of ball bearings with an appropriate clamping force without rattling. Therefore, as described in the disclosure of the conventional example, if the gripping of the sliding portion is not loosened and the processed portion is naturally finely rotated in the θ direction in a plan view and erroneous drilling is performed, the sliding portion is pressed with an appropriate gripping force. High-precision assembling work of the pair of ball bearings that sandwiches the moving part is not required, and it is possible to avoid a machining error and a complicated assembling work of the ball bearings. Moreover,
A guide plate having a vertically elongated hole for mounting the pair of ball bearings and guiding the slidable portion so as to be able to move up and down is provided on the front surface of the processing unit so as to be linearly finely movable in the left-right direction. Since the curved left and right side surfaces are held in a line contact manner by a pair of ball bearings, the linear movement of the guide plate in the left-right direction makes a plan with the slidable portion held by the pair of ball bearings as a fulcrum. The jar rotates slightly. Therefore, X
There is also provided a fine adjustment mechanism capable of correcting a mounting error of a processing portion set in the axial direction or the Y-axis direction and directing the processing portion in a normal direction. In addition, the above-mentioned pair of ball bearings also has a function of finely rotating the plunger by adjusting the eccentric direction thereof. Fine adjustment of the direction can be made with high accuracy.
If the guide plate cannot be moved linearly in the left-right direction with respect to the processing unit, simply adjusting the eccentric direction of the pair of ball bearings will improve the slidability of the mu-block with an appropriate clamping force without rattling. It can also have a function of finely adjusting the processing section in the θ direction in plan view. Moreover, the processing part
When a functional part with a cross-sectional shape other than a perfect circle is formed integrally with a main body made of a flat plate or square bar, use a special jig from the round bar stage for the processed part. There is no trouble of machining, and machining of the machining part is easy.
