Technical Field
[0001] This utility model relates to the field of cable trays passing through walls, specifically a bending device for manufacturing swing arms. Background Technology
[0002] The manufacturing process of automotive control arms requires a bending step. The typical process involves manually placing the workpiece on top of a bottom mold, then using a drive device to move a pressure block downwards, bending the workpiece. Afterwards, workers use a clamp to remove the bent workpiece from the bottom mold and place it in a storage basket. Each bent workpiece requires manual removal, which is cumbersome, labor-intensive, and inefficient. Therefore, a new technical solution is needed to address this issue. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a bending device for manufacturing swing arms, so as to solve the technical problem that the workpieces after each bending need to be manually removed and manually put into the swing arm to be bent, which is troublesome, labor-intensive and has low production efficiency.
[0004] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a bending device for manufacturing a swing arm, including a belt conveyor, a support plate installed at one end of the belt conveyor, a hydraulic cylinder installed at the top of the support plate, and a bending head provided at the drive end of the hydraulic cylinder;
[0005] An mounting plate is installed at the end of the belt conveyor away from the support plate. Two connecting plates are provided on the surface of the conveyor belt of the belt conveyor. The connecting plates are connected to the mounting plate. A bending die is provided on the bracket of the two connecting plates. A groove is opened on the inner side of the bending die. A T-shaped push rod slides through the groove. A push plate is installed at the end of the T-shaped push rod near the bending head. A return spring is sleeved on the outer side of the T-shaped push rod at the outer end of the bending die. The two ends of the return spring are connected to the bending die and the head of the T-shaped push rod, respectively.
[0006] Preferably, a cylinder is mounted on a support plate on one side of the hydraulic cylinder, and a baffle is mounted on the drive end of the cylinder, with the bottom of the baffle in contact with the conveyor belt of the belt conveyor.
[0007] Preferably, the head of the T-shaped push rod is fixedly connected to two limit rods on both sides of the end near the bending die, and the two limit rods are symmetrically distributed.
[0008] Preferably, a first bolt passes through the connecting plate and the bending die, the first bolt is threaded to the surface of the bending die, a fixing plate is installed on the drive end of the hydraulic cylinder, and a second bolt passes through both sides of one end of the fixing plate, and the second bolt is threaded to the surface of the bending head.
[0009] Preferably, the surface of the mounting plate is on the same horizontal plane as the surface of the conveyor belt of the belt conveyor, and the bending head and the bending die are on the same horizontal line.
[0010] Preferably, the external dimensions of the push plate are adapted to the internal dimensions of the groove, and the central axes of the T-shaped push rod, the groove, and the push plate are on the same horizontal line.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model combines a belt conveyor, hydraulic cylinder, bending head, bending die, T-shaped push rod, and return spring. The belt conveyor transports the swing arm to be bent between the bending head and the bending die. Then, the hydraulic cylinder is activated to push the bending head to compress the swing arm in conjunction with the bending die to bend the swing arm. When bending the swing arm, the bent swing arm pushes the push plate, which moves the T-shaped push rod and stretches the return spring. When the bending head disengages from the swing arm, the elastic force of the return spring pulls the push plate to move, causing the bent swing arm to disengage from the bending die and be placed outside the bending die. Then, the belt conveyor automatically unloads the bent swing arm, thus eliminating the need for manual loading and unloading and further improving the efficiency of swing arm bending.
[0013] 2. This utility model combines a cylinder and a baffle. When the swing arm is automatically fed and bent, the cylinder is activated to push the baffle to contact the connecting plate, thereby limiting the feeding position of the swing arm and quickly placing the swing arm between the bending head and the bending die.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0019] Example 1: A bending device for manufacturing a swing arm, see [link / reference] Figures 1 to 3 The system includes a belt conveyor 1, with a support plate 11 mounted at one end. A hydraulic cylinder 2 is mounted on the top of the support plate 11, and a bending head 23 is provided at the drive end of the hydraulic cylinder 2. An mounting plate 12 is mounted at the end of the belt conveyor 1 away from the support plate 11. Two connecting plates 13 are provided on the surface of the conveyor belt of the belt conveyor 1, and the connecting plates 13 are connected to the mounting plate 12. Bending molds 4 are mounted on the supports of the two connecting plates 13. The surface of the mounting plate 12 is on the same horizontal plane as the surface of the conveyor belt of the belt conveyor 1. The bending head 23 and the bending mold 4 are on the same horizontal line. A groove 41 is provided on the inner side of the bending mold 4, and a T-shaped push rod 42 slides through the groove 41. A push plate 43 is mounted on the end of the T-shaped push rod 42 near the bending head 23. A return spring 44 is sleeved on the outer side of the T-shaped push rod 42 at the outer end of the bending mold 4. The two ends of the return spring 44 are respectively connected to the bending mold 4 and the T-shaped push rod 42. The head is connected, and the external dimensions of the push plate 43 are adapted to the internal dimensions of the groove 41. The central axes of the T-shaped push rod 42, the groove 41, and the push plate 43 are on the same horizontal line. During operation, the swing arm to be bent is transported to the bending head 23 and the bending die 4 via the belt conveyor 1. Then, the hydraulic cylinder 2 is activated to push the bending head 23 to compress the swing arm in conjunction with the bending die 4 to bend the swing arm. When bending the swing arm, the bent swing arm pushes the push plate 43, causing the T-shaped push rod 42 to move simultaneously. The return spring 44 is stretched, and the push plate 43 is placed in the groove 41 to match the inner wall of the bending die 4, so as to avoid the push plate 43 affecting the bending quality of the swing arm. When the bending head 23 is separated from the swing arm, the elastic force of the return spring 44 pulls the push plate 43 to move and drive the bent swing arm to be separated from the bending die 4 and placed on the outside of the bending die 4. Then the belt conveyor 1 drives the bent swing arm to be unloaded automatically, so that there is no need for manual loading and unloading, further improving the bending efficiency of the swing arm.
[0020] For details, see Figure 1 A cylinder 3 is installed on the support plate 11 on one side of the hydraulic cylinder 2. A baffle 31 is installed on the drive end of the cylinder 3. The bottom of the baffle 31 is in contact with the conveyor belt of the belt conveyor 1. When the swing arm is automatically fed and bent, the cylinder 3 is activated to push the baffle 31 to contact the connecting plate 13, thereby limiting the position of the swing arm feeding, and thus quickly placing the swing arm between the bending head 23 and the bending die 4.
[0021] Further, see Figure 3The head of the T-shaped push rod 42 is fixedly connected to two limit rods 45 on both sides near the bending die 4, and the two limit rods 45 are symmetrically distributed. By contacting the outer side of the bending die 4 with the limit rods 45, the position of the push plate 43 can be restricted, thereby preventing the push plate 43 from being placed on the outer side of the bending die 4 and affecting the feeding of the next swing arm.
[0022] It is worth noting that, see Figure 2 A first bolt 5 passes through the connecting plate 13 and the bending die 4. The first bolt 5 is threadedly connected to the surface of the bending die 4. A fixing plate 21 is installed on the drive end of the hydraulic cylinder 2. A second bolt 22 passes through both sides of one end of the fixing plate 21. The second bolt 22 is threadedly connected to the surface of the bending head 23. The bending die 4 can be replaced by turning the first bolt 5. At the same time, the bending head 23 can be replaced by turning the second bolt 22. This makes it easy to replace the bending head 23 and bending die 4 of different sizes according to the size of the swing arm, thereby improving the applicability of the device.
