It is easy to shake or slide during the bending process, which affects the bending effect of angle steel. Utility Model Content

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1, such as Figure 1-4 As shown, this utility model provides a double-sided bending mold for angle steel, including: a box body 1, an adjustment component, and a positioning component; The adjustment assembly includes: two lower molds 102 are movably embedded in the upper end of the inner surface of the housing 1; round shafts 117 are fixedly installed on both sides of the opposite face of the lower molds 102; multiple grooves 103 are opened on the outer surface of the lower molds 102; support plates 104 are movably embedded in the inside of the grooves 103; and support plates 104 are fixedly installed on the opposite face of the lower molds 102. The cylindrical shaft 117 is divided into two groups, both of which pass through the housing 1. A gear 118 is fixedly installed at one end of the cylindrical shaft 117. The two gears 118 mesh with each other. A servo motor 101 is fixedly installed on the side of the housing 1 away from the gear 118. The output end of the servo motor 101 is connected to one of the cylindrical shafts 117. The servo motor 101 drives one of the lower molds 102 to rotate through the cylindrical shaft 117. The other lower mold 102 is driven by the meshing gear 118. The two gears 118 can drive the two lower molds 102 to rotate relative to each other or away from each other, thereby adjusting the angle at the intersection of the two lower molds 102, so as to better perform double-sided bending processing on the angle steel. The protective cover 116 can protect the gear 118. It should be noted that when the support plates 104 intersect inside the groove 103, the other side of the support plates 104 is always in contact with the arc plate 115. The arc plate 115 can improve the load-bearing capacity and stability of the two lower molds 102 after adjustment. A U-shaped plate 108 is fixedly installed at the center of the top outer surface of the box 1. A hydraulic cylinder 109 is fixedly installed at the top center of the U-shaped plate 108. A connecting plate 112 is fixedly installed through the U-shaped plate 108 at the output end of the hydraulic cylinder 109. An upper mold 113 is fixedly installed at the bottom of the connecting plate 112. In addition, the hydraulic cylinder 109 drives the upper mold 113 to move down through the connecting plate 112, so that the upper mold 113 presses down on the central axis of the angle steel, and the two legs of the angle steel bend inward under the action of the mold, thereby achieving the double-sided bending effect of the angle steel.

[0027] In this embodiment, a positioning rod 110 is fixedly installed on the top of the connecting plate 112. The positioning rod 110 passes through the U-shaped plate 108. A limiting block 111 is fixedly installed on the top of the positioning rod 110. The positioning rod 110 moves up and down on the outer surface of the U-shaped plate 108 along with the connecting plate 112. The positioning rod 110 can improve the stability when the upper mold 113 moves down, and the limiting block 111 can prevent the positioning rod 110 from falling off the U-shaped plate 108.

[0028] Example 2, as Figure 1-4 As shown, the positioning component includes: semi-circular grooves 114 are provided on opposite inner surfaces of the housing 1, and the semi-circular grooves 114 are concentric with the circular shaft 117; Both sides of the lower mold 102 are fixedly installed with semi-circular ring plates 105. The semi-circular ring plates 105 are movably embedded in the interior of the semi-circular ring groove 114. The outer surface of the semi-circular ring plates 105 is engraved with circumferential scale lines 106. When the lower mold 102 rotates and is adjusted, it drives the semi-circular ring plate 105 to slide circumferentially inside the semi-circular ring groove 114. The semi-circular ring plate 105 can improve the stability of the lower mold 102 during adjustment, making it easier to adjust. The circumferential scale line 106 on the outer surface of the semi-circular ring plate 105 can be used to adjust the bending angle more accurately, thereby improving the processing effect of the angle steel.

[0029] In this embodiment, multiple arc-shaped electromagnets 107 are fixedly installed on the top of the housing 1 near the outer surface of the semi-circular ring plate 105. The arc-shaped electromagnets 107 are in contact with the outer surface of the semi-circular ring plate 105. The semi-circular ring plate 105 is made of iron. When the semi-circular ring plate 105 is adjusted inside the semi-circular ring groove 114, the arc-shaped electromagnets 107 are energized to generate a strong magnetic field, causing the arc-shaped electromagnets 107 to be attracted to the outer surface of the semi-circular ring plate 105. This can prevent the semi-circular ring plate 105 from sliding and improve the stability of the two lower molds 102.

[0030] Working principle: When the servo motor 101 is turned on, it drives the lower mold 102 to rotate through the round shaft 117. The two gears 118 mesh, so the other lower mold 102 rotates with the rotation of the gear 118. The two gears 118 can drive the two lower molds 102 to rotate relative to each other or in opposite directions, thereby adjusting the angle at the intersection of the two lower molds 102. The angle steel is placed on the adjusted lower mold 102. The hydraulic cylinder 109 is turned on to drive the upper mold 113 to press down. The two legs of the angle steel bend inward under the action of the upper mold 113. The lower mold 102 provides support and reaction force. Its cavity matches the upper mold and guides the angle steel to form. When the two lower molds 102 are adjusted relative to each other, the semicircular ring plate 105 is driven to slide circumferentially inside the semicircular ring groove 114. According to the circumferential scale line 106 engraved on the outer surface of the semicircular ring plate 105, the angle of the angle steel bending can be adjusted more accurately. The semicircular ring plate 105 can also improve the stability of both sides of the lower mold 102 and prevent the upper mold 113 from shaking when it is pressed down. When the arc electromagnet 107 is energized, a strong magnetic field is generated to attract and lock the semicircular ring plate 105, so that the semicircular ring plate 105 will not slide inside the semicircular ring groove 114, thereby improving the stability of the lower mold 102.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
