Description

Technical Field

[0001] The invention relates to a general field, in particular to a thin-wall metal groove special-shaped pipe processing production line and a special rolling roller mold thereof. Background Art

[0002] Metal grooved special-shaped tubes are used in many fields of furniture and home decoration, but metal grooved special-shaped tubes are currently limited to aluminum profiles or thick-walled metal tubes. Their processing technology is relatively complicated and the raw material consumption is relatively large. There is no effective processing method for thin-walled metal grooved special-shaped tubes, especially thin-walled stainless steel grooved special-shaped tubes. At present, the steel strip is first made into a round tube, and then the round tube is pressed into a grooved round tube or square tube through later shaping, resulting in low quality of the finished product, irregular shape of the special-shaped tube, smooth transition of the groove corners of the metal tube, or the bending position cannot be consistent with the design drawing. This is probably because its processing technology adopts the post-forming process, that is, the formed round tube is deformed by extrusion to obtain the finished product. Obviously, its quality control is difficult to guarantee, which brings many inconveniences to the later use and assembly. Most importantly, the theoretical strength of the product may be seriously inconsistent with the actual product strength, and it may cause safety accidents when put into use. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a thin-walled metal grooved special-shaped pipe processing production line and a special rolling roller mold which are simple in structure, safe, reliable and easy to use.

[0004] The equipment comprises a feeding device, which is used to set up thin-walled metal steel strip raw materials to facilitate the extraction of materials in subsequent processes.

[0007] The groove pressing device adopts a double-roll groove pressing device, and two upper and lower roller molds are arranged on the rollers of the device in a relative manner. The roller molds are respectively provided with groove pressing protrusions and depressions matching the protrusions. That is to say, before the thin-walled plate is rolled up and closed, the plate is bent into a customized groove body according to the demand; in the groove pressing device, the outer diameter of the roller mold of the tail unit is larger than the outer diameter of the roller mold of the front unit;

The front-end groove pressing device unit is a single-power form, that is, a single roller actively rotates, and the rear-end groove pressing device unit is a dual-power form, that is, two rollers actively rotate.

[0009] That is, through the above-mentioned arrangement, the thin-walled plate can be pulled forward;

[0010] A guide wheel is arranged between the groove pressing devices. The front guide wheel unit is a directional guide wheel, which plays a role in positioning the plate, and the rear guide wheel unit is a constraint guide wheel. That is to say, when the thin-walled metal is pressing the groove, it is constrained by the constraint guide wheel to press the gradually formed steel plate structure, thereby assisting the gradual formation of the steel pipe.

[0011] A butt welding device is provided at the rear of the groove pressing device, and a cutting device is provided at the rear of the butt welding device.

[0017] Furthermore, the rolling roller mold comprises two rollers, a negative wheel and a positive wheel, and is characterized in that the positive wheel is provided with a groove pressing protrusion, and the negative wheel is provided with a depression matching with the positive wheel protrusion. The rolling roller mold is sequentially installed in the groove pressing device of the thin-walled metal grooved special-shaped tube processing production line and its special rolling roller mold, and the width gradually decreases from front to back, the groove pressing protrusion on the rolling roller mold gradually rises from front to back, and the depression matching with the protrusion gradually deepens from front to back; from front to back, the middle part of the wheel surface at both ends of the negative wheel gradually concave, and the wheel surface gradually wraps the end faces at both ends of the positive wheel, and the wheel surface at both ends of the negative wheel gradually transitions from a smooth curved surface to a vertical vertical surface.

[0025] Reference Figure 1 , Figure 2 and Figure 3 The thin-walled metal grooved special-shaped tube processing production line and its special rolling roller mold described in the present invention include a feeding device, which is used to set up the thin-walled metal 3 steel plate raw material to facilitate the extraction of materials in subsequent processes.

[0026] A steel strip positioning device 4 is provided at the rear of the feeding device, and a groove pressing device 1 is provided at the rear of the steel strip positioning device 4; that is, the thin-walled metal 3 is precisely positioned by the steel strip positioning device 4 so that it enters the groove pressing device 1 for groove pressing.

[0027] The groove pressing devices 1 are arranged in multiple groups in sequence, and the groove pressing devices 1 are connected to a power system, and the power system cooperates with the groove pressing devices 1 to pull the material forward.

[0028] The groove pressing device 1 adopts a double-roll groove pressing device, and roller molds are arranged on the rollers thereof. The roller molds are provided with protrusions for pressing grooves and depressions matching with the protrusions. That is to say, before the thin-walled plate is rolled up and closed, the plate is bent into a customized groove body according to demand; in the groove pressing device, the outer diameter of the roller mold of the tail unit is larger than the outer diameter of the roller mold of the front unit;

[0029] The power system includes a power assembly, which distributes power to each power unit through a reducer. The front-end groove pressing device 1 unit is a single-power form, that is, a single roller actively rotates, and the rear-end groove pressing device 1 unit is a dual-power form, that is, two rollers actively rotate;

[0030] That is, through the above-mentioned arrangement, the thin-walled plate can be pulled forward;

[0031] A guide wheel 2 is arranged between the groove pressing devices 1. The front guide wheel assembly is a directional guide wheel, which plays a role in positioning the plate, and the rear guide wheel assembly is a constraint guide wheel. That is to say, when the thin-walled metal 3 is pressing the groove, it is constrained by the constraint guide wheel to press the gradually formed steel plate structure, thereby assisting the gradual formation of the steel pipe;

[0032] A butt welding device is provided at the rear of the groove pressing device 1, and a cutting device is provided at the rear of the butt welding device.

[0033] Furthermore, a weld grinding device is provided at the rear of the butt-seam welding device.

[0034] Furthermore, an optimization shaping device is also provided at the rear of the weld grinding device. The optimization shaping device adopts a model channel form, that is, the special-shaped pipe is passed through a customized mold channel for optimization shaping.

[0035] Furthermore, an integral polishing device is also provided at the rear of the optimization and shaping device.

[0036] Furthermore, the cutting device may be a saw blade or a hydraulic shear in the prior art.

[0037] Furthermore, the steel strip positioning device 4 is arranged in the following form: the positioning device includes a support plate, a positioning plate is movably arranged on the support plate, the positioning plates are relatively arranged so as to be flexibly adjusted according to the width of the steel strip, and the channel between the two positioning plates is the thin-walled metal 3 channel; a cover plate is movably arranged on the positioning plate to fully limit and constrain the thin-walled metal 3 plate.

[0038] Preferably, both the positioning plate and the cover plate can be arranged in a movable manner with slide grooves cooperating with fasteners for positioning.

[0039] Preferably, the feeding device can be in the form of a bracket and a rotating shaft, that is, the thin-walled metal 3 material in the form of a coil is placed on the rotating shaft, which can cooperate with the rotating and drawing coil material.

[0040] Preferably, a material placement rack is also provided at the rear of the cutting device.

[0041] Furthermore, the rolling roller mold comprises two rollers, a negative wheel and a positive wheel, and is characterized in that the positive wheel is provided with a groove pressing protrusion, and the negative wheel is provided with a depression matching with the positive wheel protrusion. The rolling roller mold is sequentially installed in the groove pressing device of the thin-walled metal grooved special-shaped tube processing production line and its special rolling roller mold, and the width gradually decreases from front to back, the groove pressing protrusion on the rolling roller mold gradually rises from front to back, and the depression matching with the protrusion gradually deepens from front to back; from front to back, the middle part of the wheel surface at both ends of the negative wheel gradually concave, and the wheel surface gradually wraps the end faces at both ends of the positive wheel, and the wheel surface at both ends of the negative wheel gradually transitions from a smooth curved surface to a vertical vertical surface.

[0042] When the present invention is used, a feeding device is used to set up the thin-walled metal 3 steel strip raw material roll to facilitate the extraction of materials in the subsequent process;

[0043] The steel strip positioning device 4 accurately positions the thin-walled metal 3 so that it enters the groove pressing device 1 for pressing the groove;

[0044] The front section of the double-roller slotting machine is a single-roller power transmission, and the rear section, specifically the last two sets of double-roller slotting machines, are double-roller power transmission. The outer diameter of the roller mold of the rear section is larger than that of the front section, that is, the material is pulled forward by the change of the speed difference and the power intensity. This avoids the situation in which the thin-walled profile is fed in and the end is folded or curled, which leads to poor feeding and waste of raw materials.

[0045] While the groove is being pressed, the front guide wheel assembly is a directional guide wheel, which plays a role in positioning the plate, and the rear guide wheel assembly is a constraint guide wheel, that is, while the thin-walled metal 3 is pressing the groove, it is constrained by the constraint guide wheel to press the gradually formed steel plate structure, and assist the steel pipe to gradually form;

[0046] After the pressed steel pipe is butt welded, the weld is polished and then passed through a roller die. Specifically, the roller die mentioned here is a channel-type die customized according to the finished product form. The channel-type die is four roller-type dies arranged opposite to each other. The specific form can be an integrated or split form, so that the pipe with the weld polished is subjected to secondary optimization and shaping through the die channel;

[0047] After grinding and polishing, the material is cut and discharged.

[0048] It can be clearly seen from the above method that the thin-walled metal 3-groove special-shaped tube and its processing and production process provided by the present invention is that before the raw material, that is, the thin-walled metal 3 is welded together, or before the tube is formed, the tube grooves are pre-pressed and folded to form the edges, and then the finished product is obtained through welding, grinding, secondary shaping and overall polishing. It perfectly solves the various drawbacks brought about by the prior art of extrusion shaping of the formed tube body. Its pulling forward method can effectively avoid the situation in which the thin-walled profiles are folded and curled at the end during the feeding process, resulting in poor feeding or even waste, and is of great promotion value.

[0049] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
