Description

Equipment for making a rack with towel rail

The invention relates to sanitary ware and can be used in apartment construction and pipe bending in a factory, in particular for cold-rolled multi-layer composite pipes.

Constructively closest to the one being offered is a pipe bending device which contains a bending template fixed on a roller (in the form of a disc segment with a mold), a clamping device and a starter roller mounted on a moving bogie (USSR 573224, ΚΙ B21 D 9/00, I977 .g). The disadvantage of this device is that when bending a large diameter tube, its ovality may change, since each roller cavity covers about a quarter of the circumference of the tube to be bent and the bending mold cavity about 1/5 to 6/6.

The purpose of the present invention is to increase the bending quality of longitudinal tubes and to simplify the manufacture of a towel rail with a composite riser made of multilayer composite pipes with minimal labor.

This object is achieved by the fact that the apparatus for making a towel rail riser comprises a pipe bending device consisting of a bending and rolling roller mounted relative to the axis of the bending roller in a movable fork with a lever and a filling device. According to the invention, the machine is made as a marked table, but the pressing device comprises a collapsible template mounted on the table surface, formed by two sections - the end section corresponding to the inside profile of the towel rail curvature and - a rectangular section with a a locking plate corresponding to the external profile of the curve of the towel dryer and a pressure plate with a 'r' section, the rectangular section being provided with longitudinal grooves on the outer surface, the end section having guide rails which in cooperation with the grooves make it possible to extend the template inserts of various lengths, but the pipe bending device is mounted on a table tube in the bending area on the table and a swiveling platform. The table has markings for bending pipes of different lengths to obtain S-shaped and T-shaped towel rails with different lengths of branches and different distances between them.

The main advantage of the machine is that it is possible to obtain a uniform bending radius of the pipe without any additional controls. Thanks to the swiveling platform, the tube can be bent in different planes and at different angles, but the removable compression device of the design described allows the manufacture of towel dryers of any size. The use of a folding template is determined by the fact that bending the longitudinal tubes can disrupt the parallelism of the towel rail in the rectangular sections. In addition, the combined use of a template and bending equipment to make a riser with a towel rail allows you to reduce the bending radius of the longitudinal tube and ensure the accuracy of the geometric characteristics of the product.

Tests have shown that curved multilayer composite tubes with diameters of 32 mm and 40 mm fully meet the operating conditions and allow a bending radius of at least 5 to 3 external diameters of the tubes, without the need for a core or any other filler.

The clamping device is unique, it can be used repeatedly and in various variations, it is easy to operate. In addition, it does not need a large storage space because it is collapsible and compact.

The apparatus (Figs. 2-4) for making a riser with a towel rail comprises a pipe bending device consisting of a bending roller 4 and a starter spindle 5 mounted on a moving trolley 6 with the possibility of changing the distance between them.

The trolley is rotated by a lever 7 around the axis of the bending roller 8. The tube bending device is mounted on a pivoting platform 9, which is hinged (not shown) mounted in the corner of the table 10.

The clamping device comprises a composite template 11 consisting of two sections of the end 12 corresponding to the inside profile of the curve of the towel dryer 2 and a rectangle 13 the width of which corresponds to the distance between the towel ridge branches. which in cooperation with the grooves make it possible to extend the template by using rectangular inserts of different lengths (not shown) The guide rails are fastened with screws

16. On the support surface of the rectangular section, there are studs 17, which are disposed on the table, cooperating with the corresponding cavities on the table 10. In addition, there are two studs 18 which fix the position of the template. The clamping device also has a clamping plate 19 (fig. 5) with longitudinal legs 20 having a height equal to the diameter of the tube to be pressed into the table and the rectangular section 13. The section 13 and the flange 19 are provided with a central opening under screw 21 clamps and secures the clamping device to the table 10. In addition, the clamping device is provided with a clamping plate 22 having a recess 23 and secured by screws 25 to the end section 12 of the template 11, thereby holding the external curvature of the towel dryer. The additional cuff 26 prevents the free end of the tube from shifting (in the first bending position).

Thus, the tube is rigidly fixed to the clamping device, while the proposed roller co-operation system minimizes contact stress on the bending tube and, as a result, eliminates tube cross-sectional deformation.

The tube bending device works as follows:

The machine is mounted on a table 10 in the starting position, secured to the respective markings on the folding template 11. The engagement rollers 5 are in the starting position in the bending zone of the inlet. The tube 3 is introduced in the axial direction into the mold cavity between the roller 4 and 5 so that it is pressed against the rectangular section 13 by means of a press plate 19 and a free end clamp 26 of the tube. With the starter roller, the tube is pressed into the mold cavity and the lever 7 turns to bend the tube around the bending roller within a radius of 4 which corresponds to the radius of the bending roller. In addition, the outer barrier is the starter roller itself. The length of the tube does not affect the bending process. When the bending is complete, the support roller is moved to the starting position. It is easy to remove the bent tube from the bending template. Loosen the end of the tube, remove the pressure plate and place the bent tube in the second position (fig.3) - bend the next towel rail curvature by 180 (or 90 in straight sections of the riser first, then the other) securing the towel dryer 2 with template 11 , the pressing plate 19 and the fixing plate 22. Then the whole cycle is repeated and a riser with a p - and P - towel dryer is obtained

The technology and operation of the machine is simple, it provides a bending angle of 90 to 180, can bend pipes of almost any diameter, such as 32mm and 40mm, with different bending radii and in different planes.

This ensures the production of a high-quality towel rail made of one-piece multi-layer composite pipe with simple technology and low labor intensity. The proposed template together with the bending device ensures accurate product profile without defects in geometric parameters, without changes in ovality. Attaching a pipe bending device to a swiveling platform expands the technological capabilities of the machine, since the pipe bending operation can be performed both horizontally and vertically.

The proposed towel rail, made of one-piece multi-layered composite pipe with a bend, allows the use of a cheap and simple riser construction, as it has no threaded projections, and facilitates the installation of sanitary equipment due to its flexible design. Built with simplified technology and simple designs, the machine allows you to produce different profile risers with different configuration of towel rail at low labor cost. In addition, the fabricated and assembled towel rail is of high quality, aesthetically pleasing and ensures safe operation of the building's hot water supply system.
