Abstract

The invention belongs to the technical field of caterpillar links used on engineering machinery tracks, and particularly relates to a method for using a caterpillar link trimming die for automatic forging, wherein a lower die holder fixed with a male die is fixed on a processing platform of a press machine, cutters are arranged in cutter mounting holes, after all the cutters are mounted, the caterpillar links subjected to final forging are placed on the male die, and a female die is arranged on an upper die holder; the female die moves downwards along with the press slide block to cut off the flash, and the whole circle of flash falls onto the cutting edge of the cutter; after finishing, taking down the chain track section after trimming, and then putting in a new chain track section with trimming; when the edge of the second caterpillar track section is cut, the whole circle of flash is pressed on the first circle of flash, and when the sliding block moves to a bottom dead center, the whole circle of flash cut off for the first time is cut off by the cutter and is divided into a plurality of small flashes to fall along the inclined plane of the male die; therefore, the automatic production is realized by the circulation. According to the method, the whole ring of flash is cut into a plurality of parts and automatically falls off through the caterpillar link trimming die, so that the automation of trimming procedures is realized.

Description

Using method of caterpillar link trimming die for automatic forging

Technical Field

The invention belongs to the technical field of caterpillar links used on engineering machinery tracks, and particularly relates to a use method of a caterpillar link trimming die for automatic forging.

Background

The caterpillar track section used on the engineering machinery caterpillar track is complex in shape, multiple in forging procedures, generally comprises flattening, pre-forging, finish forging, punching, trimming and correcting, redundant flashes are cut off by the trimming procedure of the caterpillar track section after finish forging forming, the flashes are irregular in shape and complete in circle, manual trimming is adopted in the cutting process, the whole circle of flashes are taken down, automation of the whole forging process is restricted, forging efficiency is low, and labor cost is high.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention provides a using method of a caterpillar link trimming die for automatic forging.

The invention is realized by the following technical scheme: a method for using a caterpillar link trimming die for automatic forging comprises a male die and a female die, wherein the middle of the male die is provided with a protrusion with a matched caterpillar link shape, the middle of the female die is provided with a groove with a matched caterpillar link shape, and four corners of the protrusion of the male die and two sides of the middle of the protrusion are provided with cutter mounting holes; the specific trimming of the caterpillar link is as follows:

step one, fixing a lower die holder fixed with a male die on a processing platform of a press machine, installing cutters in cutter installation holes, placing a finally forged caterpillar track section on the male die after all the cutters are installed, and installing a female die on an upper die holder;

secondly, the female die moves downwards along with the press slide block to cut off the flash, and the whole circle of flash falls onto the cutting edge of the cutter;

step three, after finishing, taking down the chain track section after trimming, and then putting in a new chain track section with trimming;

step four, when the edge of the second caterpillar track section is cut, the whole circle of flash is pressed on the first circle of flash, and when the sliding block moves to a bottom dead center, the whole circle of flash cut off for the first time is cut off by a cutter and is divided into a plurality of small flashes to fall along the inclined plane of the male die; and repeating the third step and the fourth step to realize the automatic production in a circulating way.

Further, in the second step, when the press slide block moves downwards to the bottom dead center, the distance between the cutter and the female die in the vertical direction is 1-2 mm.

The invention has the beneficial effects that: according to the method, the whole ring of flash is cut into a plurality of parts and automatically falls off through the caterpillar link trimming die, so that the automation of trimming procedures is realized, and the forging efficiency is greatly improved.

FIG. 2 is a schematic view of a cutter according to the present invention;

FIG. 3 is a schematic view of the structure of the female mold of the present invention;

FIG. 4 is a schematic view of the mold assembly of the present invention;

in the figure, the device comprises a male die 1, a male die 2, a cutter 3, a female die 4 and a caterpillar track section.

Detailed Description

The invention is further illustrated below with reference to the figures and examples.

As shown in fig. 1 to 4, a method for using a caterpillar link trimming die for automatic forging comprises a male die 1 and a female die 3, wherein a protrusion with a matched caterpillar link shape is arranged in the middle of the male die 1, a groove with a matched caterpillar link shape is arranged in the middle of the female die 3, and cutter mounting holes are formed in four corners of the protrusion of the male die 1 and two sides of the middle of the protrusion; the specific trimming of the caterpillar link is as follows:

fixing a lower die holder fixed with a male die 1 on a processing platform of a press machine, installing cutters 2 in cutter installation holes, placing a finally forged caterpillar track section 4 on the male die 1 after all the cutters 2 are installed, and fixing a female die 3 in an upper die holder by adopting bolts;

secondly, the female die 3 moves downwards along with the press slide block to cut off the flash, and the whole circle of flash falls on the cutting edge of the cutter 2; when the press sliding block moves downwards to a bottom dead center (namely the lower limit position of the press sliding block), the vertical distance between the cutter 2 and the female die 3 is 1-2 mm.

Step three, after finishing, taking down the chain track section 4 after trimming, and then putting in a new chain track section 4 with trimming;

step four, when the edge of the second caterpillar track section 4 is cut, the whole circle of flash is pressed on the first circle of flash, and when the sliding block moves to a bottom dead center, the whole circle of flash cut off for the first time is cut off by a cutter and is divided into a plurality of small flashes to fall along the inclined plane of the male die 1; and the caterpillar track section 4 to be trimmed can be transmitted among the working procedures through a walking beam clamping jaw or a mechanical arm clamping jaw, and the third step and the fourth step are repeated so as to realize circulation and automatic production.

Through this caterpillar link side cut mould, cut into a plurality of parts and drop automatically with whole circle overlap, realize that the side cut process is automatic, forge efficiency and improve greatly.
