Description

Technical Field

[0001] The utility model relates to a steel material bending and forming device. Background Art

[0002] Steel is widely used in power, construction, and mechanical processing industries due to its excellent mechanical properties and electrical conductivity. During use, steel often needs to be bent into specific shapes depending on the purpose. There are two main ways to bend steel: manual bending and mechanical bending. However, manual bending requires high strength and is somewhat dangerous.

[0003] For example, the steel bending device disclosed in Chinese patent CN202111178929.X has the following shortcomings in actual use:

[0004] The above patent sets two bending limit plates and a pushing device with non-adjustable spacing. In actual use, there are steel pipes with different diameters. If the steel pipe with a smaller diameter is not clamped on the surface during bending, it may bounce up during bending, causing safety accidents. At the same time, the distance of the bending device is fixed, which is not convenient for bending different steel pipes. Therefore, a design is provided. Utility Model Content

[0005] The utility model provides a steel material bending and forming device, which can effectively solve the above problems.

[0006] The utility model is achieved in this way:

[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0034] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] like Figures 1 to 4As shown, the utility model provides a steel bending and forming device, including a workbench 1; a turntable 3 is arranged on the workbench 1; a pin 5 is arranged at the center of the turntable 3; and a first block 4 can be rotatably plugged on the pin 5. The turntable 3 is fixed to the output shaft of the motor arranged inside the workbench 1, a circular pin 5 is fixed at the center of the upper end of the turntable 3, a circular through hole is opened at the upper end of the first block 4 away from the center, and the pin 5 is inserted into the through hole, so that the first block 4 is eccentric, and the inner wall of the through hole is in contact with the outer surface of the pin 5 and can be rotated, which effectively reduces the gap.

[0036] Furthermore, the height of the pin 5 is much greater than the height of the first block 4 , thereby improving the connection stability between the pin 5 and the first block 4 .

[0037] The first block 4 and the pin 5 can rotate, so the friction between the first block 4 and the surface of the steel material can be reduced during bending, thereby reducing damage to the surface of the steel material.

[0038] like Figure 2 , 4 As shown, the spline column 8 is arranged on the turntable 3 and is spaced from the pin 5. The second block 6 can be rotatably inserted on the spline column 8, and a bending space for placing steel is reserved between the second block 6 and the first block 4; a spline groove 12 is provided at the upper end of the second block 6 away from the center of the circle, and the spline column 8 is inserted into the spline groove 12 to achieve limiting to prevent the second block 6 from rotating under force, so that the second block 6 is eccentric. Therefore, the spline groove 12 of the second block 6 is eccentrically set, so it rotates before the second block 6 is inserted, thereby changing the gap between the first block 4 and the second block 6, and then the device can bend steel of different sizes.

[0039] It should be noted that the height of the first block 4 is lower than the setting height of the second block 6, and the two are staggered. The advantages of such a setting are: (1) when the staggered first block 4 and the second block 6 roll, the contact point will constantly change, thereby reducing the friction caused by continuous contact; (2) the gap between the first block 4 and the second block 6 can serve as a heat dissipation channel to help dissipate the heat generated by friction; (3) when the staggered first block 4 and the second block 6 are in rolling contact, they can absorb and disperse the impact force and play a certain shock-absorbing role; (4) this design can provide a certain degree of flexibility, allowing relative movement between the first block 4 and the second block 6; (5) the staggered setting helps to more evenly distribute the stress generated by the load and reduce local stress concentration; (6) the staggered first block 4 and the second block 6 can provide additional stability, especially when subjected to eccentric loads.

[0040] The limiting mechanism 2 cooperates with the first block 4 and the second block 6 to limit the steel material. The limiting mechanism 2 includes a mounting seat 24, a T-shaped slider 25 slidably arranged on the mounting seat 24, and a threaded rod 26 arranged in a groove in the mounting seat 24; wherein the threaded rod 26 passes through the T-shaped slider 25 and fixes the T-shaped slider 25 on the mounting seat 24 through a fastening nut 27.

[0041] Furthermore, a groove is provided in the middle of the upper end of the mounting seat 24, and the shape of the groove is set to be an inverted "T" shape and matches the T-shaped slider 25. One end of the T-shaped slider 25 is fixedly connected to the fixing seat 23, and a long strip-shaped through groove is provided in the middle of the T-shaped slider 25.

[0042] Among them, the threaded rod 26 is inserted into the through groove of the T-shaped slider 25, and one end of the threaded rod 26 is threadedly connected with a fastening nut 27, and a gasket is arranged between the fastening nut 27 and the upper end of the T-shaped slider 25. The fastening nut 27 is screwed downward on the threaded rod 26 to fix the T-shaped slider 25 on the mounting seat 24. At the same time, the user can loosen the fastening nut 27 and then pull the T-shaped slider 25 out of the mounting seat 24 to make the threaded rod 26 slide in the through groove, thereby adjusting the protruding length of the fixing seat 23 to facilitate the bending of the steel.

[0043] At least two arc grooves are formed on the side of the fixing seat 23 away from the turntable 3, and two blocking columns 21 are detachably inserted in the two arc grooves. The head of the blocking column 21 is larger than the rod to prevent it from falling. A block 22 is fixed by bolts in the rectangular notch on the other side of the fixing seat 23. The material hardness of the block 22 is greater than that of the fixing seat 23. The block 22 will directly contact the steel. The end faces of the block 22 are flush with the surface of the fixing seat 23. The flushing effect prevents damage to the steel surface.

[0044] Furthermore, when the device bends steel, the column-shaped stopper 21 has a better effect than the flat stopper. This is because (1) the cylinder as a stopper can prevent the steel from exceeding the required angle during the bending process, thereby avoiding material damage; (2) by controlling the bending point, the cylinder can reduce the stress concentration of the steel in the bending area, reducing the risk of cracks and fractures; (3) using a cylindrical stopper can speed up the bending process, because the same bending operation can be repeated quickly, improving production efficiency.

[0045] like Figure 2 As shown, an internal thread column 9 is welded to the middle part of the upper end of the spline column 8, and a threaded bent rod 10 is threadedly connected to the middle part of the internal thread column 9. The end of the threaded bent rod 10 away from the internal thread column 9 is fixed to the fixed end of the limiting wheel 7, and the roller of the limiting wheel 7 is located at the upper end of the gap between the first block 4 and the second block 6, so that the roller of the limiting wheel 7 is in contact with the upper surface of the steel or a gap is left to prevent the steel from warping when bending.

[0046] like Figure 2 As shown, the fixing seat 23 is located on one side of the turntable 3 and is fixed with a limiting strip 11 on the side wall of the turntable 3. When the two limiting strips 11 are in contact, the gap between the first block 4 and the second block 6 is on the same axis as the end face of the fixing seat 23 and is set to an initial state to facilitate the insertion of steel. The two limiting strips 11 are set at 90 degrees when in contact.

[0047] Principle and process of this utility model:

[0048] Before using the device, the user needs to adjust the gap between the first block 4 and the second block 6 according to the diameter of the steel.

[0049] The gap adjustment method is: rotate the second block 6 to different positions and insert it into the spline column 8. Due to the eccentric structure, the orientation of the raised part of the second block 6 can be changed, and then the gap between the first block 4 and the second block 6 can be changed. This adjustment method is simple and the structure is also simple.

[0050] Then, the user inserts the T-shaped slider 25 into the middle of the mounting seat 24, and then welds two threaded rods 26 to the mounting seat 24, and pulls the T-shaped slider 25 by hand to move the stopper 22 to a suitable position, and then inserts a gasket into the threaded rod 26, and then threadably connects the fastening nut 27 to the threaded rod 26 to fix the T-shaped slider 25.

[0051] Place the steel in the gap between the first block 4 and the second block 6, and make the surface of the steel abut against the stopper 22. The user rotates the threaded bent rod 10 to make it rotate in the internal threaded column 9, thereby driving the limiting wheel 7 to move downward, so that the roller of the limiting wheel 7 is close to the steel, achieving the limiting effect and preventing the steel from bouncing up and causing personal injury.

[0052] Subsequently, the switch is turned on to complete the circuit connection, and the controller controls the motor to be powered on. The output shaft of the motor drives the turntable 3 to rotate, and then through the limiting of the first block 4, the second block 6 and the fixed seat 23, the steel can be bent around the first block 4. During the bending process of the steel, the first block 4 will rotate around the pin 5 to achieve the effect of force release.

[0053] The material of the stopper 22 is harder and has higher pressure resistance. At the same time, the stopper column 21 is subjected to force and rotates in the arc groove of the fixing seat 23, so that the steel moves more smoothly and reduces friction.

[0054] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
