The method of forging cutting teeth, comprises the following steps,
Step 1, sorting：Metal stock is selected, and carries out blank, every part of small powder uniform quality after shearing；
Step 2, heat：The small powder cut is inserted 1000-1100 DEG C is heated in heating furnace；
Step 3, roll segment：The small powder heated is passed through into blank of the forging roll roll forging in flat；
Step 4, die forging：Blank is put into the forging mold with three pieces of concave templates, passes through friction press controlled forge process mould
The punch-pin fuse of tool, by blank die forging into bucket tooth finished product；
Step 5, overlap, punching：The bucket tooth finished product for temperature of still having a surplus is subjected to overlap processing by punch press, then rushed with punch press
Hole；
Step 6, it is heat-treated：It will carry out being heated to after 825-840 DEG C in the bucket tooth finished product feeding stove after overlap, punching processing, protect
Warm 1.5-3h, carries out oil cooling afterwards, quenching.
Preferably, in step 4, punch-pin fuse is moved down with friction press sliding block, blank is compressed, is full of to blank
Three pieces of concave templates are from top to bottom in the cavity of arrangement form, and punch-pin fuse is again with friction press sliding block backhaul, and drive mechanism is pushed away
Dynamic ejector beam ejection bucket tooth finished product.
The present invention is as a result of above technical scheme, with significant technique effect：
Overall structure is relatively simple, part and plug-in unit（Only upper locked mode screw and lower locked mode screw）It is less, it is easy for installation, only
Need to lock locked mode screw and lower locked mode screw, it is easy to operate, the set-up time is saved, being installed without professional can be complete
The assembling of full mould.Each part is firmly installed, and loss is relatively low, and service life is longer.
Concave template is divided into three pieces（Number plate of cavity plate, No. two plates of cavity plate, No. three plates of cavity plate）, the level between three pieces of concave templates
Direction is not in horizontal direction showing of occurring offseting by locating slot and the cooperation firm position of projection, in die forging process
As reducing the phenomenon of concave template abrasion, improving its service life；And three's fixation, the bucket tooth that die forging comes out is adjacent two
Block concave template junction is not easy the phenomenon for overlap occur, it is possible to decrease the expense of second polishing；Other concave template is divided into three parts, side
Continue the maintenance and cleaning to concave template inwall after an action of the bowels, and be easy to produce concave template, reduce the processing stage of concave template.Set and be oriented to
Component, it is to avoid punch-pin fuse sideslip, reduces the phenomenon of each component wear in production process.
The case hardness for the bucket tooth that this technique is made is used for 52hrc-58hrc, depth of hardening zone >=15mm.Carrying out mould
Forging roll is first passed through before forging by small powder roll segment into the blank of flat, the cavity shape of the concave template formation of itself and forging mold
It is more similar, it is easy to be put into inner chamber, it is not error-prone during die forging；It is after a die forging is carried out using the forging mold of the application
It is plastic, without carrying out secondary die forging again, production stage, production equipment and production time are reduced, production effect, reduction life is improved
Produce cost.

Embodiment 2
The method of forging cutting teeth, comprises the following steps：
Step 1, sorting：Metal stock is selected, and carries out blank, every part of small powder uniform quality after shearing；
Concrete mode is as follows：First weigh the quality of blank and measure the length of blank, calculate the quality of blank per unit length
And volume, the quality of bucket tooth as needed carries out blank.
Requirement to sorting：It is wear-resisting, be not easy take exercise.
Step 2, heat：The small powder cut is inserted 1000-1100 DEG C is heated in heating furnace；Small powder surface is set to add rapidly
Heat, reduces oxide skin and is formed.In the present embodiment, the small powder cut is heated to 1050 DEG C.
Step 3, roll segment：The small powder heated is passed through into blank of the forging roll roll forging in flat；Forging roll can directly by
Small powder roll segment is easy to be subsequently inputted into progress die forging in forging mold into semi-finished product, without carry out secondary die forging again after die forging,
Production efficiency is improved, and can save artificial.And forging roll has that equipment investment is small, productivity ratio is high, low to factory building and fundamental importance
The advantages of, and it is easily achieved mechanization and automation.
Step 4, die forging：Blank is put into the forging mold with three pieces of concave templates, passes through 1600T friction press controls
The punch-pin fuse of forging mold processed, by blank die forging into bucket tooth finished product；
Step 5, overlap, punching：The bucket tooth finished product for temperature of still having a surplus is subjected to overlap processing by 250T punch presses, then uses 160T punch presses
It is punched out, it is rear to be carried out playing trade mark with 80T punch presses；
Step 6, it is heat-treated：It will carry out being heated to after 825-840 DEG C in the bucket tooth finished product feeding stove after overlap, punching processing, protect
Warm 1.5-3h, carries out oil cooling afterwards, quenching.After oil cooling and Quenching Treatment, hardness, impact toughness, the wearability of bucket tooth show
Write and improve, and obtain more martensitic structures.
In step 4, punch-pin fuse is moved down with 1600T friction press sliding blocks, compresses blank, and three pieces are full of to blank
Concave template is from top to bottom in the cavity of arrangement form, and punch-pin fuse is again with friction press sliding block backhaul, and drive mechanism promotes top
Expect bar ejection bucket tooth finished product.
The case hardness for the bucket tooth that existing method is made is about in 45hrc, and depth of hardening zone is less than or equal to 12mm.And use
The case hardness for the bucket tooth that this technique is made is 52hrc-58hrc, depth of hardening zone >=15mm.
Above-mentioned steps are simple, using special forging mold die-forging forming, without secondary die forging, second polishing, can save
Process, improves production efficiency, hand labor intensity can be reduced in addition.
In a word, presently preferred embodiments of the present invention, all equalizations made according to scope of the present invention patent be the foregoing is only
Change and modification, should all belong to the covering scope of patent of the present invention.
