Description

Technical Field

[0001] The utility model relates to the technical field of child stroller processing, in particular to a bending device for producing child strollers. Background Art

[0002] A baby stroller is a "vehicle" for babies, and requires someone to help push or pull it. A baby stroller is generally composed of a sunshade, a seat cushion, a sleeping basket, and a haze cover, and its service life is generally three to five years. The age of the baby should be taken into consideration when purchasing, and now the functions of baby strollers have been upgraded to sleeping, eating, playing, etc. The rod of a child stroller needs to be bent during production.

[0003] For example, a bending device with the authorization announcement number "CN205289338U" can easily complete the folding operation of the copper bar or aluminum bar by placing the bending component in the clamping part formed between the first connecting member and the second connecting member, and then flipping the flip rod with a small force. This not only saves time and effort, but also has a simple structure, safe operation, and low cost. However, the bending device requires the operator to manually bend the rod body, which increases the workload of the operator. At the same time, when the bending device bends the rod body, since the rod body is not fixed, the rod body will move during bending, which will result in a large error in the bending angle, which reduces the working quality of the bending device. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that an operator needs to manually bend a rod body, which increases the workload of the operator and when the rod body is bent, since the rod body is not fixed, the rod body will move during bending, which leads to a large error in the bending angle, thus reducing the working quality of the bending device, and a bending device for producing a child stroller is proposed.

[0007] Preferably, the rod bending mechanism includes a first motor, the outer wall of the first motor is fixedly connected to the workbench through a bracket, the output shaft of the first motor is fixedly connected to the worm, the worm is meshingly connected to the worm wheel, the outer wall of the worm is rotatably connected to the fixed plate through a bearing, the outer wall of the worm wheel is fixedly connected to the roller, and the outer wall of the roller is slidably connected to the bottom block through a surface-processed groove.

[0008] Preferably, the outer wall of the bottom block is slidably connected to the workbench via a slide groove, and the outer wall of the bottom block passes through the workbench via the slide groove.

[0009] Preferably, the rod body fixing mechanism includes a second motor, the outer wall of the second motor is fixedly connected to the rotating block through a bracket, the output shaft of the second motor is fixedly connected to a gear, the gear is meshed with two racks, the outer walls of the two racks are respectively fixedly connected to the two moving blocks, the outer walls of the two racks are fixedly connected to one end of the buffer spring, the other ends of the two buffer springs are fixedly connected to the pad, and the outer walls of the two moving blocks are slidably connected to the two limit rods through through holes.

[0010] Preferably, the outer walls of the two racks are slidably connected to the rotating block via a bracket and a sliding groove, and both ends of the two limit rods are fixedly connected to the inner wall of the rotating block.

[0027] Working principle:

[0028] When you need to bend the rod on the stroller:

[0029] Rod fixing stage:

[0030] First, the operator places the rod body 7 to be bent on the two rotating blocks 3, and then the operator places the rod body 7 to be bent close to the push block 6, and then connects the external power supply of the second motor 401, starts the second motor 401, and the second motor 401 drives the gear 402 to rotate, and the gear 402 drives the two racks 403 to move, and the two racks 403 drive the moving block 404 to move.

[0031] Rod bending stage:

[0032] Then, the external power supply of the first motor 201 is connected, and the first motor 201 is started. The first motor 201 drives the worm 202 to rotate, the worm 202 drives the worm wheel 203 to rotate, and the worm wheel 203 drives the roller 205 to rotate.

The push block 6 pushes the middle part of the rod body 7. Since both ends of the rod body 7 are fixed, the middle part of the rod body 7 will bend. At the same time, the upper and lower ends of the rod body 7 will also drive the rotating block 3 to rotate. After the rod body 7 is bent to a suitable angle, the first motor 201 stops working, and then the two second motors 401 reverse. In the above manner, the multiple vertical plates 5 are all away from the rod body 7. Then the second motor 401 stops working, and the operator removes the bent rod body 7 to complete the bending work of the child stroller production.
