Features of machines for openwork forging by cold stamping. Machines for cold forging azhurstal Features of various models of machines

To write an article about novelties in forging equipment I was moved by chance. Recently, I ordered a lattice for a window in one workshop. Word by word, I got into a conversation with the blacksmith, a young man of about thirty, Alexei Baryshnikov. First, the conversation turned to small business, and then quietly moved on to technical topics.

“For the time being, in our workshop, we specialized mainly in welding and cutting metal - a circle, a corner, a square,” the blacksmith said, “but there were not enough forged elements. So clients left for neighbors who have a hammer. Recently, we also took an old 75-ku hammer. Completely put in order, removed backlashes, put up cranes according to the passport. But you still have to work extremely carefully with the pedal, constantly focus on the firing pin. You make a mistake from fatigue, you don’t keep track, and instead of lightly hitting the workpiece, you strike such a blow that the almost finished part is flattened. The guys say - all because I'm not an experienced blacksmith. Is there really no normal hammer that would regulate the amplitude of the striker itself?”

Frankly, this problem surprised me. Indeed, does our industry really not produce such equipment that, on the one hand, would be affordable for small businesses, and on the other hand, would be so convenient and reliable in operation that even a beginner could easily work on it?

Yandex search led me to the factory website "Azhurstal", and then I had a conversation with the commercial director of the Azhurstal group of companies, Oleg Pavlov, who answered all my questions.

Yes, we have begun production of such a machine as "Azhur-7". It can also be used to manufacture many elements that are usually made with a hammer,” said the commercial director. - But in working with a hammer you need to have a lot of experience. Whereas a person who has never previously been engaged in artistic forging, no special permits or ranks are required for operation. A person can learn how to work on a machine in 2-3 days. Also, do not forget that this equipment designed to produce the same items in large quantities. Elements can be used both in the production of our own forging, and sold by the piece.

Apparently, this was exactly what I was looking for for Alexei Baryshnikov.

- Tell me, Oleg, what kind of parts can be made on "Azhur-7"?

What about artistic forging manually by 90%, depending on the use of molds standard or custom-made by the equipment buyer, the execution of the element is limited only by the maximum stroke of the slider 210mm and the size of the mold, approximately 200*50mm.

In other words, "Azhur-7" covers almost all the needs of blacksmiths from private workshops. And how reliable is Azhur-7? What components and mechanisms make the machine original and durable?

Our company has been specializing in the production of high-speed hydraulic presses for a long time, now there are three hydraulic press these are: Azhur-3M, PV-100 and the new Azhur-7, in the production of which only high-quality Italian components for the hydraulic system and convenient controls are used - all presses are equipped with foot pedals.

Is there a guarantee? What forms of service (ease of repair and affordable spare parts) does your company offer? After all, it happens that the machine breaks down, and spare parts need to wait for months.

Warranty 12 months. Our company has a department technical support operation, commissioning, warranty and post-warranty service. The engineers of this department will not only give qualified advice at any time of the day, but will also be able to leave at any time convenient for the client to carry out work. Since all original parts and accessories are made in our factory and always in stock, you won't have to wait for months for them, which is not the case with other manufacturers.

- What is its technical "zest" and competitive advantage before other similar (imported) machines?

The press was created from scratch, taking into account the requirements of professional blacksmiths, who make many elements manually or with a hammer, but this takes a lot of time. This is the first press designed specifically to perform such art forging elements and at the same time very affordable for small and medium businesses - RUB 410,000, including has a force of 100 Tf. There are no analogues as such, or we could not find information about them, no one produces in Russia. There are presses that differ greatly in size or cost at times, of course, you can make the same elements on them, but very few people can pay about 50,000 Euro for it.

Yes, the difference is significant. 410,000 rubles is not such a large amount for a small business, in any case, it is lifting, which cannot be said about two million rubles. And how does it work? What makes it convenient for forging?

Well, firstly, the press works much quieter than when forging with a hammer, and secondly, it has great accuracy and speed of manufacturing identical elements. I repeat, a person who has never been involved in artistic forging, no special permits or ranks are required for operation. A person can learn how to work on a machine in 2-3 days.

Small businesses don't stand idle. Is it possible to say about "Azhur-7": "I bought it, delivered it, installed it, turned it on and I'm working"? That is, this machine without a "headache"?

The machine leaves the gates of the enterprise absolutely ready for work, you just need to connect it to the mains and pour hydraulic oil into the hydraulic tank.

Everything I learned from commercial director group of enterprises "Azhurstal", told Alexei Baryshnikov. The blacksmith had already "worked hard" with the old hammer, so he accepted my information with a bang. And just recently, I met Alexei again, who nevertheless bought Azhur-7. The master shook my hand for a long time in gratitude, repeating: “Excellent machine!”.

“We, blacksmiths, do everything with our own hands and we know how important it is to be in demand among our citizens,” said Alexei. - Therefore, buying Russian equipment we vote for our country. And that's very important."

In order to effectively forge metal in a cold way, the latest machines from the Openwork series station wagon are used. Cold metal processing can be used to make many products with decorative pattern. Machines of this type are safe in operation, high efficiency, and there is no need to involve qualified personnel.

Advantages of cold forging machine Openwork

In this way, you can easily twist and bend the bars of the required section. This makes it possible to make parts of a certain type and, on their basis, assemble the finished product.

Opportunities of lathes openwork station wagon today:

Bend elements by rotating strictly according to the specified parameters. Most often combined with a spindle. Modern blacksmith and universal machine openwork is able to control the angular inclination with high accuracy.
To twist the twig, use the same machine with additional attachments.
To wind the rings, add an additional nozzle.
All forged parts are cut on a scissor unit. All side faces of the mechanism are made offset with respect to the rubbing surfaces. Thus, the cut is smooth and thoughtful.

Currently, forging machines "Azhur" are produced with a different model range.

For metal bending

As a rule, brand Azhur M-1. It carries out the production of such elements as:
