Manufacturing knives for guillotine shears with 445. Knives for cutting reinforcement
A very important and main activity of the company Mekhzavod GPO is production of knives for guillotines and knives for shear presses Russian and imported production according to customer drawings or according to GOST 25306-82.
Knives for guillotine shears
Guillotine knives, depending on the metal being cut, are made from various grades of domestic or foreign steel: 6ХВ2С; X12MF; 45NiCrMo16.
Tolerances on geometric dimensions in accordance with GOST 25306-82 ensure complete interchangeability of knives for guillotine shears and do not require any adjustment or additional grinding during installation.
Production time range from three weeks and depending on the complexity and size of the knives for guillotines and press shears. Knives for standard scissors are constantly in stock and you can purchase them in reserve.
Sharpening guillotine knives
We offer a service - sharpening flat knives for guillotine. The price is from 2 rubles. per linear mm, for a complex profile a correction factor is introduced. You can find out the exact cost from our managers.
Guillotine knives have four cutting edges. During operation, one of them becomes dull; to continue use, the knives are turned over. After all the cutting edges have become dull, the knives need to be sharpened. Knives made to dimensions in accordance with GOST 25306-82 allow up to three to four sharpenings. Technologically, the sharpening process is grinding. Knives can be ground on any surface grinding machines with a table length from 600 to 1300 mm.
When sharpening is carried out, it is necessary to ensure that in one “installation” the entire set of knives removed from one knife beam is turned over.
Specifications
Equipment knives
Cutting metal workpieces is one of the most common mechanical operations in manufacturing. For this purpose, a huge variety of equipment is used, including guillotine shears, press shears, grade shears and others. At the same time, their main working body is knives.
Advantages of use
Their distinctive feature The following characteristics can be mentioned:
- Smooth quality cut
- High performance
- Possibility of use with manual force or using a variety of drives
They are fed both along a straight path and with a given angle of inclination. There are versions placed on a special rotating frame.
The nuances of using a cutting tool
Regardless of the design features, but keeping in mind the specifics of the work process, special requirements are imposed on the tool used as a cutting tool:
- High resistance to chipping of blade material
- Maintaining cutting edge sharpness for a long time
In addition, you should carefully monitor the environment in which the equipment operates, since, as a rule, knives are made of metal containing a large number of carbon, so the blades may rust in humid environments.
Product range
Kuvandyk plant "Dolina" designs and manufactures cutting tools for guillotine shears and other types of press-forging equipment. The length of these products reaches and often exceeds 1 m. This allows you to get a long and even cut.
Moreover, their design and mounting method allow the use of different edges during the cutting process. This feature helps to increase the service life of the tool.

The cutting of reinforcement at enterprises and construction sites is carried out on specialized machines for cutting reinforcement. This equipment is especially widely used in factories for the production of reinforced concrete structures, as well as in construction. The machines allow you to successfully cut almost any steel reinforcement various shapes and sizes - strip, square and round. The quality of cutting metal fittings of different sizes and materials depends primarily on the degree of sharpening of the knife, the quality of its correct hardening and the material from which it is made.
High quality knives for cutting reinforcement carry out cutting of material up to 32 mm thick, the cutting force is 1000 N/m and above. They are used on a variety of machines that cut reinforcing steel; this equipment is used in reinforced concrete factories on the territory of procurement sites, in house-building plants, construction sites, and is used for square, round and strip steel, which has a tensile strength of 470 MPa. The equipment allows you to cut reinforcement of any size and diameter, bend and weld the ends. Each machine has its own working element - a knife for chopping or cutting reinforcement. The quality of the knife is of great importance; the productivity of the entire process depends on it.

Knives for cutting reinforcement must meet special requirements: have high durability of cutting edges, since open areas There is no way to fine-tune the equipment every time. The tool should not crumble or break even under significant loads, since it has more than one cutting edge and, in the event of a breakdown, will not be able to work out its entire service life. Knives for cutting metal reinforcement are made of alloyed tool steel 6ХВ2С for cold cutting. They are processed thermally, which allows them to achieve optimal hardness, toughness and strength, and this also increases their service life.
Knives for cutting reinforcement come in three types:
- having a smooth hole Ф12 and a chamfer for fastening a bolt with a countersunk head;
- having a threaded hole M12;
- having a threaded hole M10.
The standard overall size of knives for cutting reinforcement is 110x40 mm with a thickness of 18 mm, but if for some cases a non-standard size is required, the knife is made to order.

Guillotines , i.e. guillotine or sheet shears, are used for fast and high-quality cutting of metal. The main selection criteria guillotines is the type of production: mass, serial or piece, as well as the length of the cut, the thickness of the sheet being cut, its dimensions and mechanical strength. The technical needs of metalworking enterprises, depending on their level and capabilities, can be satisfied as simple as manual guillotines , and more complex electromechanical or hydraulic models of guillotines. Guillotine shears with electric drive are equipped with a control pedal. All guillotine models , except manual ones, can be equipped with varying degrees industrial electronics and additional options that increase their productivity. Despite the variety of drive types, the operating principle of all guillotine models is the same and consists of the following basic operations: - placing the sheet to be cut on the guillotine work table along the set stops between the upper and lower knives; - preliminary pressing of the sheet to the guillotine table using a pressure beam; - moving the upper guillotine knife, cutting; - transportation of finished parts from the cutting zone. Flat knives for metal have a dominant role in this process.
