[0002] A bridge generally refers to a structure built across rivers, lakes, and seas to enable vehicles and pedestrians to pass smoothly. During the construction of a steel tube concrete tied arch bridge, it is usually processed into several steel structure segments in a steel structure prefabrication plant, and then the steel structures are connected and fixed by metal components.

[0003] In the process of processing bridge metal components, in order to facilitate the splicing and installation of bridge metal components, it is necessary to bend the bridge metal components into a specific shape through a bending device according to actual needs for subsequent use.

The workpieces are arranged in sequence through the material guide groove and slide down, and the bending mold is driven to move by the extension of the hydraulic rod. When the bending mold contacts the lowermost workpiece, automatic feeding is realized. When the bending mold pushes the workpiece to contact the limit block, the clamping and limiting of the workpiece is realized through the action of the limit block, the bending mold and the spring until the workpiece contacts the fixed mold, and then the bending plasticity of the workpiece is realized by cooperating with the action of the bending mold, the limit block and the fixed mold.

[0006] Preferably, the lower end surface of the fixing frame is also fixed with supporting feet, and a bracket is installed between the supporting feet, and a collection box is placed on the bracket.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 7The present invention provides a technical solution: a bending device for processing bridge metal components, including a fixed frame 1, a bending die 4 and a fixed die 5. A hydraulic rod 3 is fixed to the left side of the upper end surface of the fixed frame 1, and a bending die 4 is fixed to the output end of the hydraulic rod 3. A fixed die 5 fixed to the fixed frame 1 is arranged on the right side of the bending die 4. A hopper 2 is fixed to the fixed frame 1, and a guide trough 201 is arranged at the lower side of the hopper 2. A workpiece 202 is placed in the hopper 2, and the workpiece 202 is slidably connected to the guide trough 201, and a lower end of the guide trough 201 is slidably connected to the bending die 4. A groove matching the workpiece 202 is provided on the fixed die 5 and the bending die 4. A limiting mechanism 6 is connected to the fixed die 5, and the limiting mechanism 6 includes a limiting block 601, a sliding rod 602, a fixed plate 603 and a spring 604. The limiting block 601 is arranged on the fixed die On the left side of 5, a slide bar 602 is fixed on the right end face of the limit block 601, and the slide bar 602 is slidably connected to the fixed mold 5. A fixed plate 603 is fixed to the right end of the slide bar 602, and one end of a spring 604 is fixed on the fixed plate 603, and the other end of the spring 604 is fixed on the fixed frame 1. The workpieces 202 slide downward in sequence through the guide groove 201, and the bending mold 4 is driven to move by the extension of the hydraulic rod 3. When the bending mold 4 contacts the lowermost workpiece 202, automatic feeding is realized. When the bending mold 4 pushes the workpiece 202 to contact the limit block 601, the clamping and limiting of the workpiece 202 is realized through the action of the limit block 601, the bending mold 4 and the spring 604, until the workpiece 202 contacts the fixed mold 5, and then the bending plasticity of the workpiece 202 is realized by cooperating with the action of the bending mold 4, the limit block 601 and the fixed mold 5.

[0028] A support leg 101 is also fixed to the lower end surface of the fixing frame 1, and a bracket 102 is installed between the support legs 101, and a collection box 104 is placed on the bracket 102; a guide plate 103 is also fixed to the lower end surface of the fixing frame 1, and the guide plate 103 is installed obliquely, and the left end of the guide plate 103 is located above the collection box 104;

[0029] When using the bending device for processing bridge metal components, Figure 1-Figure 6As shown, first, the cut workpiece 202 is placed in the hopper 2, and the workpieces 202 are arranged in sequence in the guide trough 201 due to their own gravity, and the lowermost workpiece 202 contacts the fixed frame 1. At this time, the bending die 4 is located on the left side of the lowermost workpiece 202. During processing, the bending die 4 is driven to move to the right by controlling the extension of the hydraulic rod 3. When the bending die 4 contacts the lowermost workpiece 202, the lowermost workpiece 202 is forced to move to the right. At this time, the bending die 4 blocks the lower end opening of the guide trough 201 to prevent the next workpiece 202 from moving downward. When the workpiece 202 moves to the right until it contacts the limit block 601, the clamping and limiting effect of the workpiece 202 can be achieved through the action of the limit block 601 and the bending die 4. At this time, the workpiece 202 and the bending die 4 are The groove on the bending die 4 cooperates to achieve the limit of the workpiece 202. The workpiece 202 continues to move right, so that the limit block 601 is forced to move to the right. The sliding guide effect between the slide bar 602 and the fixed die 5 can ensure the stability of the movement of the limit block 601. At this time, the spring 604 is forced to shrink. When the workpiece 202 contacts the fixed die 5, the hydraulic rod 3 applies pressure to the bending die 4. With the action of the bending die 4 and the fixed die 5, the bending plasticity of the workpiece 202 can be achieved. After the processing is completed, the bending die 4 is driven to move to the left and reset through the contraction of the hydraulic rod 3. At this time, under the elastic action of the spring 604, the limit block 601 is reset synchronously. When the limit block 601 is reset, the bending die 4 is separated from the workpiece 202. Figure 4 As shown, at this time, the workpiece 202 falls onto the guide plate 103 through the opening on the fixing frame 1 under the action of its own gravity, and the workpiece 202 slides into the collection box 104 for collection under the guidance of the guide plate 103. When the bending die 4 is reset, the bending die 4 no longer blocks the lower end opening of the guide groove 201, so that the next workpiece 202 automatically falls to contact with the fixing frame 1. According to the above principle, the automatic loading and unloading of the workpiece 202 can be realized without manual operation, which greatly improves the processing efficiency.

[0030] A transmission mechanism 7 is also installed on the right side of the upper end surface of the fixed frame 1. The transmission mechanism 7 includes a fixed rod 701, a slider 702, a first connecting rod 703 and a second connecting rod 704. The fixed rod 701 is symmetrically fixed to the fixed frame 1 front and back, and the slider 702 is slidably connected to the fixed rod 701; one end of the first connecting rod 703 is rotatably connected to the slider 702, and the other end of the first connecting rod 703 is rotatably connected to the fixed plate 603; one end of the second connecting rod 704 is rotatably connected to the slider 702, and the other end of the second connecting rod 704 is rotatably connected to the punching mechanism 8; the punching mechanism 8 includes a movable frame 801, an ear plate 802, a guide rod 803, a motor 804, a drill chuck 80 5 and a drill bit 806, the movable frame 801 is symmetrically distributed front and back about the center line of the fixed frame 1, and the movable frame 801 and the second connecting rod 704 are rotatably connected; the lower end surface of the movable frame 801 is symmetrically fixed with an ear plate 802, and the ear plate 802 and the guide rod 803 are slidably connected, and the guide rod 803 is symmetrically fixed on the fixed frame 1 front and back; the movable frame 801 is also fixed with a motor 804, and a drill chuck 805 is fixed at the output end of the motor 804, and a drill bit 806 is clamped on the drill chuck 805; the length of the drill bit 806 is greater than the sum of the side width of the fixed mold 5 and the diameter of the workpiece 202, and the drill bit 806 corresponds to the position of the circular hole opened on the fixed mold 5 and the bending mold 4;

[0031] During the processing of the workpiece 202, if Figure 1-Figure 6 As shown, when the limit block 601 is forced to move, the fixed plate 603 is synchronously driven to move, and the slider 702 is forced to move through the transmission effect of the first connecting rod 703. The sliding guide effect between the slider 702 and the fixed rod 701 can ensure the stability of the movement of the slider 702. When the slider 702 moves, the transmission effect of the second connecting rod 704 can make the movable frame 801 forced to move, and the sliding guide effect between the ear plate 802 and the guide rod 803 can ensure the stability of the movable frame 801. The motor 804, the drill chuck 805 and the drill bit 806 are driven to move in a stable linear motion. At this time, the motor 804 is started synchronously, and the drill chuck 805 and the drill bit 806 are driven to rotate by the motor 804. When the drill bit 806 penetrates the side of the fixed mold 5 and contacts the workpiece 202, the drilling processing of the workpiece 202 can be achieved. At this time, due to the clamping and limiting effect of the bending mold 4 and the limit block 601 on the workpiece 202, the stability of the workpiece 202 can be guaranteed. After the processing is completed, the finished product of the workpiece 202 is as follows Figure 7 As shown, the opening on the workpiece 202 can facilitate the later installation and fixation of the workpiece 202;

[0032] To sum up, the automatic loading and unloading structure of the workpiece 202 can greatly improve the processing efficiency of the workpiece 202. In conjunction with the linked punching mechanism 8, drilling operations can be performed simultaneously during the bending process of the workpiece 202, thereby reducing the processing steps of the workpiece 202 and further improving the processing efficiency of the workpiece 202. This is the working principle of the bending device for processing bridge metal components.
