Description

Technical Field

[0001] This utility model relates to the technical field of cold-formed steel bending equipment, specifically a cold-formed steel bending device. Background Technology

[0002] Cold-formed steel bending equipment is a key piece of equipment in the metal forming field, widely used in industries such as construction, automobiles, and furniture. For example, it is used to bend solid bars or hollow tubes. Since the outer diameter of solid bars or hollow tubes is not unique during bending, different bending clamping dies need to be changed to meet the bending requirements. Fixed clamping dies can only be used for bending solid bars or hollow tubes of a single size. Especially when bending hollow tubes, a mandrel is needed for internal support to prevent the hollow tube from wrinkling during bending. Hollow tubes with different inner diameters have different requirements for the size of the mandrel, and a single-size mandrel cannot meet the bending needs of hollow tubes with different inner diameters.

A first support plate 9 is fixedly connected to the upper end of the first fixed frame 8 near the rear side.

A movable first mold clamp 16 is fixedly connected to the front side of the second mold support plate 15.

[0036] According to the outer diameter of the solid rod or hollow tube, the first fixing bolt 12 is removed, thereby removing and replacing the fixed first mold clamp 11 and the movable first mold clamp 16. The dimensions of the fixed first mold clamp 11 and the movable first mold clamp 16 change according to the outer diameter of the solid rod or hollow hole. The first mold support plate 10 and the second mold support plate 15 remain unchanged. The movable first mold clamp 16 is pushed by the first hydraulic telescopic rod 13 to cooperate with the fixed first mold clamp 11 to stably clamp the solid rod or hollow tube for stable fixation during bending.

[0037] The equipment body 1 includes a receiving groove 101. The receiving groove 101 is opened inside the equipment body 1. A second lead screw 102 is rotatably connected to the inner wall of the equipment body 1. The second lead screw 102 is connected to the output shaft of a third motor 104 via a first belt 103 under the action of a first pulley. The third motor 104 is set in the receiving groove 101. A second movable frame 105 is provided through the second lead screw 102. A third lead screw 106 is rotatably connected to the inner wall of the second movable frame 105. The rear end of the third lead screw 106 is connected to the output shaft of a fifth motor 107. A fourth movable frame 108 is provided through the third lead screw 106. A rotating cylinder 109 is rotatably connected through the inner wall of the fourth movable frame 108. A first through slot 110 is opened through the rotating cylinder 109.

[0038] The fifth motor 107 drives the third lead screw 106 to rotate, causing the fourth moving frame 108 to move and adjust on the third lead screw 106, thereby adjusting the position of the clamped solid rod or hollow tube for subsequent clamping and bending. The third motor 104 drives the second lead screw 102 to rotate through the first belt 103, causing the second moving frame 105 to move and feed on the second lead screw 102 for adjusting the position of the solid rod or hollow tube. The outer ring of the rotating drum 109 is connected to the output shaft of the sixth motor through a meshing gear set. Under the action of the sixth motor, the rotating drum 109 is driven to rotate through the meshing gear set, thereby driving the clamped and fixed solid rod or hollow tube to rotate and adjust.

[0039] The right end of the rotating drum 109 is fixedly connected to a first fixed support plate 111 in a ring array. A second hydraulic telescopic rod 112 is fixedly installed through the upper and lower first fixed support plates 111. A third hydraulic telescopic rod 113 is fixedly installed through the front and rear first fixed support plates 111. A first clamp 114 is fixedly connected to the inner end of the third hydraulic telescopic rod 113 and the inner end of the second hydraulic telescopic rod 112.

[0040] Based on the outer diameter of the hollow tube or solid rod, the first clamp 114 is adjusted under the action of the second hydraulic telescopic rod 112 and the third hydraulic telescopic rod 113, thereby clamping and fixing the hollow tube or solid rod.

[0041] A fourth lead screw 115 is rotatably connected to the inner wall of the equipment body 1. The fourth lead screw 115 is located to the left of the third lead screw 106. Under the action of the second pulley, the fourth lead screw 115 is connected to the output shaft of the fourth motor 117 via the second belt 116. The fourth motor 117 is located in the receiving groove 101. A third movable frame 118 is provided through the fourth lead screw 115. A sliding groove 119 is provided at the upper end of the third movable frame 118. A slide frame 120 is slidably connected to the third movable frame 118 via the sliding groove 119. A second through groove 121 is provided through the slide frame 120. A core rod 126 is provided through the second through groove 121 and the first through groove 110.

[0042] The fourth motor 117 drives the fourth lead screw 115 to rotate via the second belt 116, thereby causing the third moving frame 118 to move on the fourth lead screw 115 for the propulsion adjustment of the mandrel 126.

[0043] The left side of the slide 120 is fixedly connected to a second fixed support plate 122 in a circular array. A fourth hydraulic telescopic rod 123 is fixedly installed through the upper and lower second fixed support plates 122. A fifth hydraulic telescopic rod 124 is fixedly installed through the front and rear second fixed support plates 122. The inner ends of the fifth hydraulic telescopic rod 124 and the fourth hydraulic telescopic rod 123 are both fixedly connected to a second clamp 125.

[0044] Based on the inner diameter of the hollow tube, the second clamp 125 is adjusted under the action of the fourth hydraulic telescopic rod 123 and the fifth hydraulic telescopic rod 124. This is used for clamping and adjusting the mandrel 126 during its forward and backward movement. The mandrel 126 is only clamped and fixed during its feed adjustment. When the mandrel 126 moves and adjusts under the action of the fourth moving frame 108, it drives the slide 120 to slide and adjust within the slide groove 119. Further, 1. Positioning and support: Before the bending action begins, the mandrel is sent to... 1. **Predetermined position (tangent point slightly behind)** provides internal support for bending; 2. **Bending and "yielding":** As the tube begins to bend by rotating and dragging, it gradually wraps around the cavity of the bending mold; during this process, the straight mandrel itself does not follow the bending, it remains straight; 3. **Naturally formed gap:** Because the mandrel is straight and the tube is bending, in the latter half of the bending arc, the inner wall of the tube naturally disengages from the straight mandrel, forming an increasingly larger gap. This naturally formed gap is the mandrel's "escape channel," and this part represents the bending process in existing technology.

[0045] Combination Figures 1-5The specific operation of the cold-formed steel bending equipment of this embodiment is as follows: Based on the outer diameter of the hollow tube or solid bar, the first clamp 114 is adjusted under the action of the second hydraulic telescopic rod 112 and the third hydraulic telescopic rod 113 to clamp and limit the hollow tube or solid bar. Based on the inner diameter of the hollow tube, the second clamp 125 is adjusted under the action of the fourth hydraulic telescopic rod 123 and the fifth hydraulic telescopic rod 124 for clamping and adjusting during the mandrel's advance and retreat. Based on the outer diameter of the solid bar or hollow tube, the first clamp 125 is disassembled... Fixing bolts 12 allow the fixed first mold clamp 11 and the movable first mold clamp 16 to be removed and replaced. The dimensions of the fixed first mold clamp 11 and the movable first mold clamp 16 vary depending on the outer diameter of the solid rod or hollow hole. The first mold support plate 10 and the second mold support plate 15 remain unchanged. The movable first mold clamp 16 is pushed by the first hydraulic telescopic rod 13 to cooperate with the fixed first mold clamp 11 to stably clamp the solid rod or hollow tube for stable fixation during bending. The fifth motor 107 drives the third lead screw 106 to rotate. The fourth moving frame 108 moves and adjusts on the third lead screw 106, thereby adjusting the position of the clamped solid bar or hollow tube for subsequent clamping and bending. The third motor 104 drives the second lead screw 102 to rotate via the first belt 103, causing the second moving frame 105 to move and feed on the second lead screw 102 for position adjustment of the solid bar or hollow tube. The first motor 6 drives the worm gear 4 to rotate via the worm 5, thereby driving the bending frame 7 to rotate via the transmission shaft 3 to bend the solid bar or hollow tube. The outer ring of the rotating drum 109 is connected to the output shaft of the sixth motor through a meshing gear set. Under the action of the sixth motor, the rotating drum 109 is driven to rotate through the meshing gear set, thereby driving the solid rod or hollow tube clamped and fixed to rotate and adjust. The fourth motor 117 drives the fourth lead screw 115 to rotate through the second belt 116, thereby causing the third moving frame 118 to move on the fourth lead screw 115 for the advance adjustment of the core rod 126. A central processing unit is provided for control, and the central processing unit model is S7-1500.
