Description

[Detailed description of the invention] a. Industrial application field This invention relates to a plate butting device, and more specifically, it is used to determine the processing position of a plate in a plate processing machine such as a shear or punching machine. This invention relates to a plate abutting device used.

b. Prior Art Conventionally, in the work of a shearing machine, a punching machine, etc., when the front side of a plate is set as a reference position, a plate abutting device has been used as a positioning device. This plate abutting device is generally slidably provided in a T-groove or the like, and is fixed in a predetermined position by pressing the bottom surface of the T-groove with a push bolt or the like.

c Problems to be solved by the invention As mentioned above, the conventional plate abutment device is fixed by pressing the bottom of the T-groove with a push bolt, etc., and does not leave an impression on the bottom of the T-groove by the push bolt. As a result, fine adjustment became difficult and positioning accuracy tended to deteriorate. The object of this invention is to provide a highly accurate positioning plate abutment device that improves upon these conventional drawbacks.

d Means for solving the problem This invention was made in view of the conventional problems as mentioned above. A plate material butting device is formed by engaging a sliding member having a flexible plate material abutting member so as to be able to adjust and fix the position, and the sliding member is pressed down by presser bolts screwed onto both ends of the sliding member. An intermediate member is provided to be movable up and down in recesses formed on the lower surface of both ends of the sliding member, and the area of the contact surface where the intermediate member contacts the bottom of the groove is larger than the lower end face of the holding bolt. The intermediate body is urged upward by an elastic member attached to a moving member and held within the recess.

e Effect With the above configuration, when the intermediate body is pushed down by the presser bolt, the sliding member is pushed up as a reaction, and the sliding member can be fixed in the T-groove. Since the abutting surface of the intermediate body is wide, no indentations or the like will be formed on the bottom of the T-groove, and the above-mentioned conventional problems can be solved. Further, due to the action of the elastic member, the intermediate body is always held within the recess of the sliding member and does not fall off.

f Example Next, an example of this invention will be described based on the drawings. Figure 1 shows the main body of a shearing machine to which this invention is applied, in which an upper blade 5 is attached to a ram 3 that reciprocates up and down by an appropriate means such as a crank mechanism, and a lower blade 9 is attached to a lower blade stand 7. ing. The plate material W is
The plate material pressing device 1 is positioned by the plate material abutting device 13 attached to the lower blade stand 7 and the table 11.
5 and cut by the upper blade 5 and lower blade 9.

An embodiment of the plate abutting device of this invention is shown in FIGS. 2 and 3. That is, this plate material abutting device 13 consists of the main parts of a sliding body 17, a plate material abutting member 19, a holding bolt 21 which is a fixing member, and an intermediate body 23. A plate abutting member 19 is provided on the sliding body 17 so as to be rotatable around a pin 25 . As shown in FIG. 2, the plate abutting member 19 is normally stopped at the position shown in the figure because the right side of the pin 25 is heavier than the left side. Holder bolt 21
is screwed into threaded grooves provided at both left and right ends of the sliding member 17 in FIG. The intermediate member 23 is in contact with the intermediate member 23.

Insert this plate material butting device 3 into the T-slot provided in the lower blade stand 7 or table 11, and press the push bolt 21.
When screwed in, the intermediate body 23 presses the bottom of the T groove,
The sliding body 17 is pushed upward and fixed in the T-slot. In this case, since the area where the intermediate body contacts the bottom surface of the T-groove is much larger than the area of the tip of the push bolt, no indentation is produced on the contact surface. In this state, the plate can freely move on the plate abutting device 13 from the right to the left, but is stopped at the left end position of the plate abutting member 19 when moving from the left to the right. Therefore, if the distance between this position and the lower blade 9 of the shearing machine is set to a predetermined dimension, the plate material fed from the right side can be handled by this plate material abutting device 13.
By abutting it from the left side, it can be positioned and cut to a predetermined size.

This invention can be implemented in aspects other than the embodiments without departing from the technical idea described above.

g. Effects of the invention As can be understood from the above description of the embodiment, the present invention has a plate material abutment that can freely appear and retract from the top surface of the table 11 in a T-groove formed in the table 11 of a plate processing machine. The sliding member 17 having the member 19 is engaged with the sliding member 17 in a position adjustable and fixed manner to form a plate material butting device, and is pressed down by presser bolts 21 screwed onto both ends of the sliding member 17. The intermediate body 23 is provided to be movable up and down in the recesses formed on the lower surface of both ends of the sliding member 17, and the area of the contact surface where the intermediate body 23 contacts the bottom of the groove is larger than the lower end surface of the presser bolt 21. , the intermediate body 23 is urged upward by an elastic member 27 attached to the sliding member 17 and held within the recess.

As is clear from the above configuration, in the present invention, the intermediate body 23 is urged upward by the elastic member 27 attached to the sliding member 17, and
It is always held within the recess. Therefore, even if, for example, an oil film exists at the bottom of the T-groove and the intermediate body 23 tends to stick to the bottom, the intermediate body 23 will not be detached by the action of the elastic member 27. This prevents the intermediate body 23 from coming into close contact with the bottom of the groove even after the presser bolt 21 is loosened.

Furthermore, since the intermediate body 23 is held within the recess of the sliding member 17 by the elastic member 27,
For example, when the sliding member 17 is removed from the groove, the intermediate body 23 will not fall off, and the sliding member 17 can be easily attached to and removed from the groove.
