[0002] Hardware products are auxiliary and accessory products used in daily life and industrial production. In the early days, they were mostly made of metal materials such as gold, silver, copper, iron, and tin, hence the name. When processing hardware products, a bending machine is needed. A bending machine is a machine that can process metal materials to form a V-shaped bend.

[0003] The prior art patent document with the publication number CN219632294U provides a bending device for hardware products, which can bend both ends of the pipe synchronously by setting a bending mechanism, and can control the bending angle to improve the bending efficiency. However, the pipe to be bent is directly put into the machine, and there is no positioning mechanism, so the bending position lacks precision, which cannot meet the processing with high requirements on the bending position, and can only process one pipe at a time, so the efficiency is low. Utility Model Content

[0010] As a further description of the above technical solution:

[0011] The driving mechanism is a motor 1, which is installed on the inner bottom side of the fixed column. The bottom driving end of the motor 1 passes through the operating table and is fixedly connected to the top of one of the gears.

[0012] As a further description of the above technical solution:

[0013] The height difference between adjacent placement platforms is greater than the diameter of the processed pipe.

[0014] As a further description of the above technical solution:

[0015] The inner cavity width of the bending plate is equal to the diameter of the pipe.

[0016] As a further description of the above technical solution:

[0017] Supports are installed at the four corners of the bottom of the operating table.

[0018] As a further description of the above technical solution:

[0019] A hidden bin is arranged on the top rear side of the operating table, a second motor is installed in the hidden bin, and a discharging rack is fixedly connected to the top driving end of the second motor.

[0020] The utility model has the following beneficial effects:

[0021] 1. In the utility model, firstly, the hardware pipe is placed at a suitable position on the placement table according to its length. The motor drives the bending plates on both sides to slide along the paths of their respective arc-shaped slide grooves through gears.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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 creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-4 The utility model provides an embodiment: a bending machine for the production of hardware products, including an operating table 1, the top of the operating table 1 is symmetrically provided with an arc-shaped slide 2, the arc-shaped slide 2 is slidably connected with a slide rod 3, the top of the slide rod 3 is fixedly connected with a bending plate 4, a positioning block 5 is provided in the bending plate 4, and the side of the positioning block 5 is stepped with a plurality of placement tables 6, a transmission mechanism is provided at the bottom of the operating table 1, the transmission mechanism is connected to the slide rod 3, the top of the operating table 1 is located between the two bending plates 4 and is provided with a driving mechanism for driving the transmission mechanism to operate, the transmission mechanism includes two gears 10, the top ends of the two gears 10 are rotatably connected to the bottom of the operating table 1, the two gears 10 are meshed and connected, the two gears 10 are respectively fixedly connected to the bottom ends of the slide rods 3 on both sides through a connecting rod 9, and a fixed column 7 is fixedly connected to the top middle end of the operating table 1 for supporting the pipe bending process. It plays an auxiliary role. The driving mechanism is a motor 8, which is installed on the inner bottom side of the fixed column 7. The bottom driving end of the motor 8 passes through the operating table 1 and is fixedly connected to the top of one of the gears 10; the pipe to be processed is placed on the placement table 6 at the corresponding position according to its length, and the motor 8 is started to drive one of the gears 10 to rotate, thereby driving the other meshing gear 10 to rotate, and then through the connecting rod 9, the slide bar 3 slides along the internal path of the arc-shaped slide groove 2, and the angle of the bending plates 4 on both sides gradually becomes smaller, thereby achieving the effect of bending the pipe. Since the pipe is placed on the placement table 6 of the same length, the positioning block 5 is used to position the pipe to achieve accurate bending of the corresponding position. In addition, multiple layers of pipes can be stacked on the same placement table 6 at the same time, and placement tables 6 of different heights can place pipes of different lengths, so that multiple pipes can be bent at the same time, thereby improving processing efficiency.

[0031] The height difference between adjacent placement tables 6 is greater than the diameter of the processed pipe, so that multiple pipes of the same length can be placed on the placement table 6 at one time. The inner cavity width of the bending plate 4 is equal to the diameter of the pipe, which is beneficial to the stability of the pipe and avoids shaking during the bending process; supports are installed at the four corners of the bottom of the operating table 1. A hidden bin 11 is provided on the top rear side of the operating table 1, and a motor 2 is installed in the hidden bin 11, and a discharge rack 12 is fixedly connected to the top driving end of the motor 2. When the processing is completed, the motor 2 drives the discharge rack 12 to be ejected upward from the inside of the hidden bin 11. Since the discharge rack 12 is a U-shaped design, the bent pipe is hung on the top of the discharge rack 12 and is ejected from the inside of the bending plate 4. The worker can then take it out, making it more convenient and quick to retrieve the material.

[0032] Working principle: the pipe to be processed is placed on the placement table 6 at the corresponding position according to its length, the motor 8 is started, driving one of the gears 10 to rotate, thereby driving the other meshing gear 10 to rotate, and then through the connecting rod 9, the slide bar 3 slides along the internal path of the arc slide 2, and the angle of the bending plates 4 on both sides gradually becomes smaller, thereby achieving the effect of bending the pipe. Since the pipe is placed on the placement table 6 that meets the length, the positioning block 5 is used to position the positioning block 5 to achieve accurate bending of the corresponding position of the pipe. In addition, multiple layers of pipes can be stacked on the same placement table 6 at the same time, and placement tables 6 at different heights can place pipes of different lengths, so that multiple pipes can be bent at the same time at one time, thereby improving the processing efficiency. When the processing is completed, the motor 2 drives the discharging rack 12 to push upward from the inside of the hidden bin 11. Since the discharging rack 12 is a U-shaped design, the bent pipe is hung on the top of the discharging rack 12 and is pushed out from the inside of the bending plate 4. The worker can take it out, making it more convenient and quick to take materials.
