Description

Technical Field

[0001] The utility model relates to the technical field of threaded steel welding, in particular to a threaded steel welding pressurizing device. Background Art

[0002] Rebar welding is a process of heating and melting the contact parts of two or more rebars, and then cooling and solidifying them into a whole. When welding rebars, preliminary preparation is usually required, including cleaning the oil, oxides and other impurities on the surface of the welding part, and selecting suitable welding rods and welding processes.

[0003] Most of the existing threaded steel welding pressurization devices include a base, and a first fixing plate is symmetrically arranged on the front and back sides of the middle of the top of the base to fix the threaded steel to be welded. A first support frame is symmetrically arranged on the left and right sides of the top of the base, and a slot is opened on the upper part of these support frames, and a cylinder is arranged in the slot. The function of the cylinder is to provide the pressure and stability required for welding through air pressure to ensure the welding quality. For example, the Chinese patent with the publication number CN217316373U and the name is: A simple welding pressurization device, the test piece to be welded is confined in the cavity inside the sleeve by a sleeve, and the upper half sleeve and the lower half sleeve are fixed by a clamp. Under high temperature conditions, the test piece to be welded is heated and expanded. Since the high temperature linear expansion coefficient of the test piece to be welded is greater than the high temperature linear expansion coefficient of the sleeve, the expansion degree of the test piece to be welded will be greater than the expansion degree of the sleeve, and the distance between the test piece to be welded and the sleeve will gradually decrease until they fit together. The sleeve produces an extrusion force on the test piece to be welded, and the top surface of the inner cavity of the sleeve is a flat structure, so that the test piece to be welded is expanded. During the welding process, after contacting the sheath, it can adjust and balance the surface pressure by itself to achieve pressure balance. However, during its actual use, due to the different sizes and specifications of different rebars, the air flow channel in the cavity of the same size cannot meet the use of rebars of different specifications. When rebars with larger size, diameter and stiffness are used, a single air flow channel will not be able to perform fast, accurate and stable pressurization operations, thereby reducing the accuracy of the overall welding, thereby limiting the overall scope of use. Therefore, the present application provides a rebar welding pressurization device to meet the needs. Utility Model Content

[0004] The purpose of the present application is to provide a threaded steel welding pressurizing device, which solves the problem in the prior art that threaded steels of different specifications cannot be quickly adapted, thereby achieving the purpose of improving overall flexibility of use and adaptability.

By providing a plurality of sealing plates for sealing the sealing tube body, the utility model can control the electric push rod autonomously through an external controller according to the specific size specifications of different accommodating cavities during its use, so that the electric push rod pushes the driving member to move downward along the airflow tube body. When the driving member slides to the top of the sealing member, the external controller will also drive the ejection structure to fall by driving the electric slide rail, and apply the thrust of the ejection structure to the sealing plate body, so that the sealing plate body rotates along the mounting shaft under the action of its force, and then changes its own disposal position, so that the sealing tube body is in an open state, and then keeps the sealing tube body unobstructed. At this time, the external cylinder can be directly opened to allow the cylinder to effectively convey air pressure through the sealing tube body, and then adjust the setting position and fixing force of the threaded steel inside the accommodating cavity, so as to ensure the stability and accuracy of the welding operation.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0028] Combine the following Figure 1-5 The embodiment shown describes the technical solution of the utility model:

[0029] It includes an upper fixing plate 1 and a lower fixing plate 2, and an accommodating cavity 3 is opened on the opposite side of the upper fixing plate 1 and the lower fixing plate 2, and the threaded steel can be placed inside the accommodating cavity 3 for fixing, the upper fixing plate 1 and the lower fixing plate 2 are connected with a sealing member 5 through an airflow tube body 4, and the airflow tube body 4 and the sealing member 5 are used to connect the accommodating cavity 3 with the external cylinder, and a plurality of penetrating sealing tube bodies 6 are fixedly inserted at the top of the sealing member 5, and the interior of the sealing tube body 6 is rotatably connected to two sealing plate bodies 8 through two mounting shaft bodies 7, and the two sealing plate bodies 8 are used to seal the sealing tube body 6, and a plurality of electric push rods 10 are fixedly connected to the interior of the airflow tube body 4 through a plurality of adjusting ports 9, and the free ends of the plurality of electric push rods 10 are fixedly connected to the same driving member 12 through an adjusting plate 11, and a plurality of driving ports 13 are opened on the driving member 12, and an ejection structure is arranged inside the driving port 13 through an electric slide rail, and the ejection structure is used to switch the use state of the sealing plate body 8.

[0030] Before using it, the upper fixing plate 1 and the lower fixing plate 2 can be directly set at appropriate positions, and the threaded steel to be processed can be placed inside the accommodating cavity 3, and then the electric push rod 10 can be autonomously controlled by an external controller according to the specific size specifications of different accommodating cavities 3, so that the electric push rod 10 can drive the driving member 12 to move up and down along the airflow tube body 4. When the driving member 12 slides to the top of the sealing member 5, the electric slide rail can be directly driven by the external controller to drive the ejection structure to fall, and then the ejection structure applies its thrust to the sealing plate body 8, so that the sealing plate body 8 rotates along the mounting shaft body 7 under the action of its force, and then changes its own disposal position, so that the sealing tube body 6 is in an open state, and then the sealing tube body 6 is kept unobstructed. At this time, the external cylinder can be directly opened to allow the cylinder to effectively convey air pressure through the sealing tube body 6, and then adjust the setting position and fixing force of the threaded steel inside the accommodating cavity 3, and then ensure the stability and accuracy of the welding operation.

[0031] The ejection structure includes an electric slide rail fixedly connected to the inside of the driving port 13 , and the electric slide rail is fixedly connected to a connecting vertical shaft 15 through a supporting plate 14 , and the bottom of the connecting vertical shaft 15 is rotatably connected to two control members 16 .

[0032] Two adjacent driving ports 13 and the sealing tube body 6 are located on the same longitudinal axis, and the driving member 12 is slidably connected above the sealing member 5 .

[0033] During its use, the electric slide rail can effectively drive the connecting vertical shaft 15 and the control member 16 to move downward synchronously, so that the bottom of the control member 16 can be inserted into the interior of the sealing tube body 6. At this time, the two control members 16 distributed at an acute angle can synchronously convert their own downward movement force into thrust acting on the sealing plate body 8, so that the sealing plate body 8 is forced to rotate along the installation shaft body 7. After the rotation, a certain channel will be generated between the opposite sides of the two sealing plate bodies 8, so that the sealing tube body 6 is in an open state.

[0034] An elastic member 17 is fixedly connected to one side opposite to two adjacent control members 16 , and a protective sleeve 23 is fixedly connected to the bottom of the driving port 13 . The two control members 16 and the protective sleeve 23 are distributed in a triangle.

[0035] During its use, the triangularly distributed control member 16 can better directly apply its own moving force to the center of the sealing plate body 8, thereby pushing the sealing plate body 8 to rotate rapidly. At the same time, after the control operation is completed, when the electric slide rail drives the connecting vertical shaft 15 to rise, due to the limitation of the size of the driving port 13 itself, it will cause a certain restraining force on the control member 16, so that the control member 16 rotates under the action of its restraining force, and squeezes the elastic member 17, so that the elastic member 17 is deformed and shortened due to the force, so that the angle between the two control members 16 is reduced, so as to better store them. At this time, the setting of the protective cover 23 will quickly protect the bottom of the driving port 13, so that the bottom of the driving port 13 remains stable.

[0036] Two limit blocks 18 are fixedly connected inside the sealing tube body 6, and a magnetic plate 19 is fixedly connected inside the limit block 18. A magnetic block 21 is fixedly connected to the top of the sealing plate body 8 through an installation port 20, and the magnetic block 21 is adapted to the magnetic plate 19.

[0037] During the period when the sealing plate 8 seals the sealing tube body 6, the magnetic attraction force between the magnetic plate 19 and the magnetic block 21 will effectively increase the fixing effect of the sealing plate 8 and the sealing tube body 6 during the sealing period, thereby ensuring the stability of the sealing plate 8 and the stability of the overall sealing effect, making its overall use more stable and convenient, and avoiding the possibility of it falling off.

[0038] A rubber pad 22 is fixedly connected to the top of the sealing plate body 8 , and an anti-slip protrusion is provided on the rubber pad 22 .

[0039] The setting of the rubber pad 22 can effectively protect the driving point of the control member 16, so that when the control member 16 pushes the sealing plate body 8 to rotate, it will directly contact the rubber pad 22. After the rubber pad 22 buffers its thrust, its thrust is evenly applied to the sealing plate body 8, so that the sealing plate body 8 can rotate stably, thereby avoiding the possibility of bumping or damaging the sealing plate body 8.

[0040] Two connection ports 24 are formed at the bottom of the upper fixing plate 1 , and two connection members 25 are fixedly connected to the top of the lower fixing plate 2 . The connection members 25 can be slidably inserted into the connection ports 24 .

[0041] The sliding plug-in structure of the connecting port 24 and the connecting piece 25 will effectively enable the upper fixing plate 1 and the lower fixing plate 2 to be quickly positioned and installed, thereby ensuring the stability of the installation of the upper fixing plate 1 and the lower fixing plate 2 during their use, while also making the accommodating cavity 3 more stable during use, thereby improving the clamping effect of the cylinder on the internal air pressure of the accommodating cavity 3.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
