Description

Porous position mold side punching device

technical field

The invention relates to a stamping die, in particular to a side punching device for a multi-hole die.

Background technique

Automobile stamping parts have the remarkable characteristics of complex structure and different shapes. Many parts need to be opened on the side. At present, for parts with side openings that are not too demanding in size, the method of first plane punching, and then bending or deep drawing is generally adopted. However, for some side holes with relatively high size requirements, it can only be realized by side punching. At present, the standard oblique device for side punching on the market is mainly for the popular parts to be punched, and is not suitable for several side punches. The stamping parts to be punched with ten holes, therefore, it is necessary to invent a new multi-hole die side punching device for this type of parts to be punched.

detailed description

The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

As shown in Figure 1, the side punching device of the multi-hole mold includes an upper mold and a lower mold. The side punch head 33 in the lower plate of the upper die, the side punch die 5 installed on the lower die, the spring 1-7 connected between the upper plate of the upper die and the lower plate of the upper die, the side punch The head 3 includes a mounting box 3-5 fixed in the lower plate of the upper mold and having intersecting first chute and second chute inside, slidably connected in the first chute and can face the piece to be punched 4, the slider 3-2 to be punched is inserted into the slider 3-2 and inserted into the second chute and moves with the upper plate of the upper die to drive the slider 3 -2 moving oblique block 3-1, the lower end of the slider 3-2 is connected with the punch fixing block 3-3, the punch 3-4 connected to the punch fixing block 3-3 is installed on On the installation box 3-5 and after the upper die goes down, it cooperates with the side punching die to clamp the part 4 to be punched so as to prevent the part 4 to be punched from being deformed during the punching process. 6. The upper and lower ends of the punch fixing block 3-3 are respectively provided with a chute with a large belly and a small mouth, and the lower end of the slider 3-2 and the upper end of the pressing block 3-6 are provided with T-shaped bumps, so The protrusion is inserted in the sliding slot, the punch is inserted in the punch fixing block 3-3 and its upper end is pressed against the sliding block 3-2. A plurality of paired side punch die heads 3 and side punch dies are installed on the patrix.

The upper plate of the upper mold includes an upper mold base 1-1, the first upper mold 1-2, and the second upper mold 1-3 from top to bottom, and the lower plate of the upper mold includes a third upper mold from top to bottom. Template 1-4, fourth upper template 1-5, fifth upper template 1-6, the oblique insertion block 3-1 is fixed on the first upper template 1-2, and the spring 1-7 is connected to Between the second upper template 1-3 and the third upper template 1-4. The lower mold includes a first lower template 2-1, a second lower template 2-2, a third lower template 2-3, and a lower mold base 2-4 from top to bottom.

The overall action is to press the material first and then punch the hole, and then the punch exits the die and the workpiece to be punched under the state of pressing the material, that is, the stripping is realized, and the side punching process ends. During the side punching process, the upper mold of the side punching is driven downward by the slider of the punch press as a whole. When the fifth upper mold plate 1-6 and the pressing block 3-6 press the piece to be punched, as the upper mold upper plate continues to Descending, the spring 1-7 is compressed, the third upper template 1-4, the fourth upper template 1-5, the fifth upper template 1-6 and the installation box 3-5 fixed in this board remain motionless, obliquely inserted Block 3-1 slides in the slot hole of slide block 3-2, drives slide block 3-2, punch fixing block 3-3 and punch 3-4 to slide in installation box 3-5, and punch 3-4 Start to enter the workpiece 4 to be punched and the side punching die 5. When the spring 1-7 is compressed, that is, when the second upper template 1-3 and the third upper template 1-4 are closed, the effective part of the punch 3-4 Completely enter the part to be punched 4 and the side punching die 5, and the side punching is completed, as shown in Figure 2, Figure 6 and Figure 7; then the upper die of the side punching is driven upward by the slide block of the punching machine, and the compressed The spring 1-7 slowly releases the elastic force, and the third upper template 1-4, the fourth upper template 1-5 and the fifth upper template 1-6 maintain the pressing state (that is, remain still) under the action of the elastic force, as shown in Figure 9 As shown, the oblique insertion block 3-1 moves upward along with the upper die of the side punch, and drives the slider 3-2, the punch fixing block 3-3 and the punch 3-4 to slide in the installation box 3-5, and the punch 3- 4 Leave the side punching die 5 and the part 4 to be punched, and when the compression stroke of the spring 1-7 is released, the punch 3-4 completely leaves the side punching die 5 and the part 4 to be punched to complete the stripping process, Then the entire side punching upper die is driven upward by the slide block of the punching machine, and the side punching process ends. It should be pointed out that the oblique insertion block 3-1 and the slider 3-2 are mechanically linked, as shown in Figure 8, which can effectively ensure that the effective part of the punch 3-4 completely enters the workpiece 4 to be punched when the mold is closed. And side punching die 5, can guarantee again that when side punching upper die goes up, punch 3-4 withdraws from waiting for punching part 4 and side punching die 5 completely.

The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present invention, and the purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and not to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention, such as the punch allows to be processed into corresponding shapes according to different punching shapes; by adjusting the installation angle of the punch and the corresponding slider, side punches with different angles can be punched. Changes such as holes should be covered within the protection scope of the present invention.
