Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a deburring device that is attached to a press or cylinder unit, etc. for deburring cast products, press-formed products, forged products, die-cast products, etc. It is.

(Prior art) As shown in Fig. 6, when a core to be extracted in the vertical direction and a core to be extracted in the horizontal direction are used in the inner deep part of the die-cast product A, vertical Bariro,
b occurs.

Such vertical burrs were removed by attaching a burr removal mechanism to the press machine.

That is, the deburring mechanism is lowered, and the vertical deburring mechanism is removed.
A cutting blade (D) was pushed between the vertical bars and (R) from above (R), and the vertical bars and (B) were bent to cut from the base, and the cut surface was hand-finished to make it smooth.

(Problem that the invention aims to solve) Manual work is required after the multiple vertical burrs that are located deep inside the product and protrude toward the press slide direction are bent and removed from the base, which is extremely inefficient. There was a problem.

(Means for solving the problem) The present invention is designed to remove vertical burrs that occur deep inside the product by moving the cutting blade along the surface near the vertical burr and cutting it from the base plate. A slide plate is provided that is slidable along the slide plate and elastically supported at one end, and a mounting member that is slidably attached to the slide plate and a mounting member that is fixed to the slide plate are provided, and these mounting members are slidable in the vertical direction. a cutting blade is attached to the slide plate, a horizontal cylinder is fixed to the slide plate, the horizontal cylinder is actuated to move one mounting member, and the other mounting member is moved by abutting against the abutment member; To provide a deburring device that removes a plurality of vertical burrs from the lateral direction.

(Function) Activate the horizontal cylinder, move one mounting member to remove the vertical burr, and move another mounting member integrally with the return movement of the slide plate whose contact surface hit the striking member to remove another vertical burr. It can be resected from the root in the lateral direction.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1, 2, 3, and 4.
is fixed to the upper plate 2 of the press mold,
A slide plate 4 that can be slid laterally is provided in a guide groove 3a of a guide member 3 fixed at the lower part of the base plate 1, and a horizontal cylinder 6 is fixed to a support member 5 vertically provided at the end of the slide plate 4. It has been done.

A guide member 7 whose upper end is fixed is provided at the intermediate portion of the slide plate 4, and a mounting portion 8a is slidably mounted in the guide groove 7a of the guide member 7.The support piece 9 of the mounting member 8 and the rod of the horizontal cylinder 6 are provided. 6a end is attached via a support shaft 10.

The other end of the slide plate 4 is connected to the guide groove 1 of a guide member 11 whose upper end is fixed to the base plate 1.
1a, and a mounting member 12 having an upper end 12a fixed to the other end of the slide plate 4 is vertically provided.

Attachments 15 and 16 having cutting blades 13 and 14 at their tips are removably attached to the attachment members 8 and 12, respectively, and rods of vertical cylinders 17 and 18 are mounted on the projecting pieces of the attachment members 7 and 12. The ends are attached to corresponding fixtures 15, 16, and the fixtures 15, 16 are slidable along the vertical guide grooves 8a, 12a.

One end of the spring 19 is fixed to the end surface of the slide plate 4, and the other end of the spring 19 is fixed to the base plate 1. An abutment member 20 whose upper end is fixed to the base plate 1 and hangs vertically is connected to the guide member 3 and the guide member 11. The abutment surface 8b of the attachment member 8 can freely abut against the side surface 20a of the abutment member 20.

In the figure, 21 and 22 are stoppers.

Since the present invention is constructed as described above, when the press slide descends to the bottom dead center, the horizontal cylinder 6 is activated to move the mounting member 8 to the right, and the mounting member 15 is Move the installed cutting blade 13 in a direction perpendicular to the press slide direction and elastically cut the left vertical burr along the burr generation surface. The slide plate 4 was moved by the reaction force when the abutment surface 8b of the attachment member 8 hit the side surface 20a of the abutment member 20 and the elastic force of the spring 19, and was attached to the fixture 16 of the attachment member 12. The cutting blade 14 moves to the left to cut off the vertical burr on the right side.

That is, the cutting blade 14 moves in the opposite direction to the advancing direction of the cutting blade 13, cutting off the right vertical burr from the root in the lateral direction.

Since the cutting blades 13 and 14 have downward elasticity due to the vertical cylinders 17 and 18, respectively, the vertical burr can be removed from the root in the lateral direction along the vertical burr generation surface.

FIG. 5 shows another embodiment of the present invention, in which there are three mounting members, namely mounting members 23, 24, 25, for fixing the mounting tool for mounting the cutting blade, and an impact member 2.
6 and 27 are provided, and the vertical burrs, holes, and rims are removed from the horizontal direction, and their functions and effects are the same as in the previous embodiment.

(Effects of the invention) The present invention attaches cutting blades to a plurality of mounting members via mounting tools, moves one mounting member, and moves other mounting members by the reaction force that hits the impact member.
First, the cutting blade attached to the moving mounting member cuts off the vertical burr at the innermost part of the product from the horizontal direction, and the cutting blade of the moving mounting member cuts off another vertical burr from the root from the horizontal direction. Increases the efficiency of vertical burr removal, making it possible to efficiently remove vertical burrs even if there is a difference in height on the vertical burr surface that occurs deep inside the complex interior, eliminating the need for manual work and significantly improving productivity. .
