Description

Description of the invention

The invention relates to the equipment for processing metals by pressure, in particular to the equipment for the production of 2 bent profiles and can be used in the production of bent profiles of various configurations from strip or strip material.

There is a well-known profiling machine, mostly of the medium type, which contains a frame on which a number of profiling cages with upper and lower shafts with profiling rolls are fixed. The upper and lower shafts of each profilezginal cage are driven in opposite rotation from a single drive for the profilezginal state 70. In order to expand the technological capabilities and simplify the change of profiling rolls, one of the support racks of each profiling cage is made movable in the horizontal plane, and the shafts of the profiling cages are made of folded and detachable ones (see the description of the invention to the patent of Ukraine Mo19872, IPC 82105/06, 25.12.97, Byul. Mob).

The claimed object and the analogue have the following essential features: the profiling stands contain 12 rows of profiling cages with upper and lower profiling rolls.

Obtaining the expected technical result when using an analogue is prevented by the following reasons.

When forming a profiled state of a known structure, a profiled cage of a complex design is used as a module. As a result, the entire state formed by a relatively large number of these cages, designed for the production of a bent profile of the most complex configuration, turns out to be difficult to operate. Due to this, in the known profiled state, transshipment of profiled rolls and readjustment of profiled cages and the entire profiled state as a whole is complicated with frequent changes in the shape or size of the bent profile, the production of which requires a new number of profiled cages. This leads to a decrease in productivity during the production of bent profiles of a diverse range on one stand, especially profiles of small sizes, which are manufactured in small batches. In addition, the presence of a single state of the drive for the entire profiling, which is connected to the profiling rolls of numerous profiling cages through spindles and gear cages, leads to high costs of electricity in the production of bent profiles of a simple configuration, for the production of which several profiling cages are enough.

The closest in terms of features to the claimed invention is the profile forming unit chosen as a prototype, which contains a coil unwinder, a correcting device, a cutting device, a butt-welding machine, a profile forming machine, a correcting machine and a device for dividing profiles into measuring "Z length The profiled bed is formed by profiled cages with upper and lower profiling rolls installed in series on a common bed. Each profiling cage has cast support posts and upper and lower shafts with profiling (with rollers) are installed in them on bearing supports. The profiling rolls are made of disk forming elements and are driven from a single 39 for the profiling state of the drive connected to the rollers of profile cages Through spindles and ee, gear cages. Depending on the shape and standard size of the bent profiles being produced, the profile cage can contain 20-30 profile cages. Each such profile cage can be considered as a module of the profile cage. In the prototype, the roll blank unwinder, correct the device, the cutting " device and the butt-welding machine are fixed on a common frame, which is installed with the possibility of transverse C 50 movement relative to the axis of the profiled state. Removal, if necessary, from the composition of the profiled unit of part of the equipment of its entrance part to ensure free access to the first

"Iz" of the profile cage allows to expand the range of manufactured profiles due to individual production of closed profiles from pre-made welded pipes. Due to the complexity of reconfiguration, such profile units are usually designed for the production of bent profiles in large batches (see the description of the invention to the patent of the Russian Federation Mo2088357, IPC B2105/06, 1997). b The object being claimed and the prototype have the following essential features: the profiling units sl contain an unwinder of the rolled billet, a profiling stand formed by successively installed profiling cages with upper and lower profiling rolls, and a device for dividing profiles into equal lengths.

Ge) 20 Obtaining the expected technical result when using the prototype is hindered by the following reasons.

Due to the complex design of the profiled machine as a whole, formed according to the principles known from the state of the art with a relatively large number (20-30) of profiled cages designed for the production of a profile of a complex configuration, due to the presence of a single drive for the entire profiled machine, which is connected to the rolls of numerous profilezginal cages through spindles and gear cages, complicated readjustment of 29 profilezginal cages and the entire profilezginal state as a whole with frequent changes in shape or size. of the manufactured bent profile. In the process of continuous long-term transshipment of all the profilezginal cages, the profilezginal unit is idle. This leads to a decrease in productivity when ensuring the production of bent profiles of a diverse assortment on one profiling unit, for the production of which it is necessary to build a different number of profiling cages each time. These shortcomings of the 60 prototype are especially evident when small batches of profiles are produced in relation to small sizes.

In addition, the presence of a single drive state for the entire profiler, which is connected through spindles and gear cages to the upper and lower rolls of numerous profiler cages, which form a profiler state for the production of a bent profile of the most complex configuration, leads to high costs of electricity in the production of bent profiles of a simple configuration, for the production of which a few professional cages are enough.

The invention is based on the task of creating such a modular profile engineering unit, in which improvement by changing the location of elements, introducing new elements and changing the form of execution of elements would allow, when using the invention, to ensure the achievement of a technical result, which consists in simplifying readjustment and increasing productivity in the production of bent profiles of a diverse assortment, especially profiles for small sizes, which are produced in small batches.

The claimed modular preventive unit is characterized by such essential features that are expressed by defined concepts sufficient for their identification, aimed at solving the task and sufficient for achieving the expected technical result in all cases covered by the scope of Article 7 of legal protection.

The claimed modular profiling unit includes a roll blank unwinder, a profiling stand formed by serially installed profiling cages with upper and lower profiling rolls, and a device for dividing profiles into measured lengths. The profilezginal bed is composed of modules, each of which contains a bed and from two to five 7/5 profilezginal cages are fixed on it. Moreover, each module is supplied with an individual drive and a transfer gear box for connection with the lower profiling rolls of each profiling cage included in this module. At the same time, the modules and the device for dividing the profiles into measured lengths are supplied with flanges, which are intended for the mutual connection of these equipment elements when forming a profile unit.

It is preferable that each module contains four profiled cages fixed on the frame of the module. In some cases, in each module, it is advisable to connect the transfer gear box, intended for connection with the drive of the lower profiling rolls of each profiling cage, to the drive through a chain transmission.

If it is necessary to correct bent profiles, it is advisable to supply the profile unit with the correct machine, which is supplied with flanges for connection with the adjacent module and with a device for dividing the profiles into measured LENGTHS.

Depending on the thickness of the rolled blank, the shape of the cross-section of the finished profile and the design of the device for dividing profiles into measured lengths, this device can be located: - at the beginning of the profile-rolling unit in front of the first module in the course of moving the blank for cutting the flat blank into measured lengths; у зо - before the last module in the process of moving the workpiece to cut the profile into measured lengths before the final bending of its elements; and, - according to the last module during the movement of the workpiece for cutting the profile into measured lengths after the final bending of its elements; - according to the correct machine in the process of moving the workpiece for cutting into measured lengths of the profile after about 5 minutes of its correction. co

In a separate case, each profile cage contains support racks and the upper and lower shafts with profiling rollers are installed in them on bearing supports. The frame of each module is made of welded channel profiles, the walls of which face each other. I-beam or channel profiles can be used as such profiles. Each support rack of the profile cage is made in the form of separate vertical racks, which are fixed on the corresponding walls of rolled profiles in a place specified with coordinate pins to form grooves for bearing supports. The support racks are connected to each other by rotating traverses, on which the pressure screws for the bearing supports of the upper shafts are installed. ;" When using the invention, it is expected to achieve a technical result, which consists in simplifying readjustment and increasing productivity in the production of bent profiles of various assortments, especially profiles of relatively small sizes, which are manufactured in small batches. b In addition, when using the invention, it is also expected to achieve an additional technical result, which consists in reducing the cost of electricity in the production of bent profiles of a simple configuration, for the production of which a small number of profile cages is required. ko Between the set of distinctive features of the invention and the technical result achieved, there is the following cause-and-effect relationship. The execution of the profiled frame module from not one, but preferably from four profiled cages fixed on the module frame, the supply of the module with an individual drive and the presence of flanges for connecting the modules to each other and to other devices of the profiled unit ensure the versatility of the profiled unit composed of such modules. One such module can be used as, for example, a 4-cell bending machine for the production of bent ov profiles of a non-complex shape, for example, with one bending point, such as corner bent profiles with identical or non-identical shelves.

P» The profile bending machine formed by two connected modules can be used to produce bent profiles with two bending points, for example, channel and zeta-shaped bent profiles.

The profile bending machine, composed of three connected modules, can be used for the production of trough-shaped, C-shaped and closed non-welded bent profiles. The use of a profile forming machine, composed of four, five or six modules, is advisable in the production of bent profiles of a complex configuration, for example, multi-grade bent profiles with corrugations and double-thickness elements, corrugated sheet bent profiles. Thus, having only six modules with the total number of profile cages the same as in the profile condition known from the state of the art, it is possible 65 to ensure the production of bent profiles of a diverse assortment, using at the same time not all the profile cages of the condition, but only the necessary modules of the profile state When changing the standard size or shape of the manufactured bent profile, only the involved modules of the profile state can be adjusted. Such modules can be completed in advance with the necessary profile elements, and when switching to the production of a new profile, it is necessary to simply replace the old modules with new ones, by assembling a new profile assembly from them. At the same time, the free modules can be used to compose a profiled state for individual production of a bent profile of a different shape, for example, a closed profile from a pre-made welded pipe, as in the prototype. The profiling unit and the profiling stage, composed of interchangeable modules, can be located next to each other to simplify the mutual movement of modules during reconfiguration. All this significantly increases productivity, 70 especially, in the production of profiles of relatively small sizes and produced in small batches. In addition, during the production of bent profiles of a simple configuration, electricity consumption is significantly reduced, because not a single very powerful electric drive is used for the entire profile machine, designed for the production of bent profiles of a complex configuration, but only individual relatively low-power electric drives of those modules involved in the production of this bent simple configuration profile. 15 In some cases, the connection of the distribution gear box with the drive through a chain transmission makes it possible to make the module of the profiled state more compact due to a more appropriate choice of the location of the drive in relation to the profiled cages. Such a layout of the module is especially appropriate when, for example, it is necessary to use a planetary gear motor as a drive.

In specific examples of implementation, the claimed modular profile unit is composed of three modules 1, 2 and 3 (Fig. 1-3). Module 1 contains four profilezginal cells 4-7, module 2 contains four profilezginal cells 8-11 and module C also contains four profilezginal cells 12-15. Each group of cages 4-7, 8-11, and 12-15 is fixed on a separate frame of the corresponding module 1, 2, and 3. The frame of each module, on which the profiled cages are fixed, is made of welded channel profiles, for example, 16 17 (fig. 4 and 5), the walls of which face each other. Channel rolling profiles 16 and 17 are connected to each other by two beams, one of which is marked by position 18 (Fig. 5).

The support racks of all profile cages are made in the form of separate vertical racks, some of which for the first two profile cages 4 and 5 of module 1 are marked in Fig. 4 and 5 by positions 19-23. The vertical joists are fixed in pairs on the corresponding walls of the channel rolling profiles 16 and 17 using base pads and bolts in the place specified by the diagonal pins. at

Vertical racks of each profile cage installed in pairs are connected to each other by turning traverses. Thrust screws for the bearing supports of the upper shafts are installed on these traverses. So, for example, the vertical racks 19 and 20 of the profile cage 4 of module 1 are connected to each other by a rotating traverse 24, which is installed on the vertical rack 20 with the ability to rotate around a finger 25 and is fixed in the vertical rack 21 with a quick-removable pin 26 (fig. 4 and 5). A pressure screw 27 is installed on the rotary traverse 24 for the bearing support 28 of the upper shaft 29 of the profile cage 4 (Figs. 4 and 5). Upper and lower shafts with profiling rollers are installed in the bearing supports fixed in each profiling cage between the vertical posts. In each profiling cage, the upper and lower profiling rolls are formed by replaceable forming elements, which are fixed on the corresponding shafts with the help of distance elements and a nut. So, for example, the upper profiling roll of the profile cage 4 is formed by variable forming elements 30, which are fixed on the upper shaft 29;" profile cage 4 with the help of distance elements 31 and nut 32. The lower profiling roll of this cage is formed by variable forming elements 33, which are fixed on the lower shaft 34 with the help of distance elements 35 and nut C6 (Fig. 5).

Each of the modules 1-3 is supplied with an individual planetary motor-reducer 37 and a kinematic transmission gear box 38 connected to it, which is connected only to the lower shafts of each profiled cage of this module (fig. 5). So, for example, the transfer gear box 38 of module 1 is connected to the lower shaft 34 of the profiled cage 4 by means of half-couplings 39 and 40.

Each of the modules 1-3 of the profile bed is supplied with flanges fixed at the ends of each channel of the rolled profile of the bed. These flanges are intended for connecting modules to each other or to other devices of the profiled unit. The flanges have openings that are coordinated with respect to the base surfaces of the respective base platforms on which the vertical struts of each profile cage are located. So, for example, a flange 41 with holes 42 and 43 (Fig. 5) is attached to the front end of the channel rolled profile 16 of the bed of the module 1. A flange 44 with holes 45 and 46 is attached to the front end of the channel rolling profile 17 of the bed of module 1. Similar flanges are attached to the rear ends of the channel rolling profiles 16

P" and 17, one of which, designated by position 47, is shown in fig. 4.

Each module of the profile state has an individual control unit. So, for example, module 1 is supplied with a control unit 48, which is located inside the channel rolled profile 17 (Fig. 4). The modular profiling unit is supplied with an unwinder 49 of a roll blank for profiling, a device 50 for introducing the blank and a device 51 for dividing profiles into measured lengths. At the end of the modular profiling unit, the correct machine 52 and device 53 for receiving ready-made profiles are installed. The devices of the modular profile unit are supplied with flanges for mutual connection with the modules and with each other. All the elements of the modular profile unit are arranged on a common bed V5 94.

In specific implementation examples, depending on the thickness of the roll blank for profiling and its elastic properties, the shape of the cross-section of the finished profile and the design of the device for dividing profiles into measured lengths, this device can be located in different places of the modular profiling unit. So, in case of individual production of graded profiles, for cutting flat

Blanks into measured lengths device 51 for dividing profiles into measured lengths, made in the form of flying scissors, can be installed at the beginning of the profiling unit behind the device 50 for inserting the blank in front of the first module 1 in the course of moving the blank and is connected to them by means of flanges ( Fig. 1). When profiling from a continuous workpiece of open profiles, it is advisable to cut the profile into measured lengths with flying scissors before the final bending of its elements in order to prevent distortion of the shape of the profile at the point of cut. In this case, the device 51 for dividing profiles into measured lengths, made in the form of flying shaped scissors, can be installed in front of the last module

In the course of movement of the workpiece and connected to it and to module 2 with the help of flanges (Fig. 2). In this case, the module 1 with the help of flanges is connected to the device 50 for . introduction of the workpiece. In the examples illustrated in Fig. 1 and 2, the module 3, installed at the end of the profiling stage, is connected to the /5 device 53 for receiving ready-made profiles. When profiling semi-closed and closed profiles from a continuous blank, it is advisable to cut the profile into measured lengths with a flying saw after the final bending of its elements to the given shape. In this case, the device 51 for dividing profiles into measured lengths, made in the form of a flying saw, should be installed behind the last module Z in the course of moving the workpiece, and if there is a correct machine 52 - behind it and connected to this correct 2o machine using flanges (Fig. 3).

The modular profile unit in one of the examples of a specific implementation, shown in Fig. 3, works as follows. The blank 55 for profiling from the strip material is wound from the unwinder 49 of the roll blank, passed through the device 50 for inserting the blank and successively fed into each profiling cage 4-15 modules 1-3 profile state. During the rotation of the lower shafts of the profiling cages, connected to the individual drives of each module, for example, the motor-reducer 37 (Fig. 4), the workpiece for profiling is successively moved in the gauges formed by the "forming elements of the lower and upper profiling rolls of all the profiling cages of the three modules 1-3 of the preventive state. In each such caliber, for example, formed by forming elements 30 and

C3 of the profile cage 4 (Fig. 5) bends the profile elements to the specified angles. After the sequential bending of the elements of the bent profile in the profile cages 4-15 of the modules 1-3 of the profile state, a bent profile 56 is obtained, which is made on the correct machine 51. Next, the bent profile 56 of the given configuration is cut with the device 51 for dividing the profiles into measured lengths and c is received by the device 53 for receiving ready-made profiles.

If it is necessary to produce a bent profile of a different standard size or a new configuration, reconfiguration of the 5 Modular profile unit is very simple. First, those modules with profiled condition are dismantled, the profiling rolls of which will not be used in the production of a new profile.

The new profiled frame is composed using profiled frame modules with pre-assembled forming elements necessary for the production of the bent profile of the new configuration.

Due to the quick connection of profile modules with the help of flanges, which are already ready for work, the duration of the idle state is significantly reduced with frequent changes in the shape of the new profile, which is manufactured in 7-3).

Yes, when using the invention, it is ensured that the technical result is achieved, which consists in simplifying the readjustment and productivity improvement in the production of bent profiles of various assortments, especially profiles of relatively small sizes, manufactured in small batches.
