Description

Technical Field

[0001] The utility model relates to the technical field of bearing flanging processing, in particular to a safe and efficient automatic bearing flanging machine. Background Technique

[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy. During the production process of bearings, sometimes it is necessary to perform a flanging operation on the bearings. In the existing flanging processing technology for bearings, generally, the bearings are placed in a flanging die and flanged by stamping.

[0003] In order to achieve the purpose of safe and automated production, the prior art uses a manipulator to grab raw materials, and then grabs them away again after stamping and flanging. However, since the bearings are clamped by the manipulator both during the process of placing the raw materials and taking away the bearings, the time between two stamping and flanging operations is relatively long, which affects the efficiency of stamping and flanging. Therefore, we propose a safe and efficient automatic bearing flanging machine. Content of the Utility Model

[0004] The purpose of the utility model is to provide a safe and efficient automatic bearing flanging machine. By enabling the die to be driven to rotate intermittently, it is convenient and fast to put bearings into different dies under the guiding action of the guide cylinder and the hopper, and then be driven by the rotation to be under the die head for stamping and flanging. Then, the flanged bearings can be adsorbed by magnetic attraction, and then collected under the guiding action of the guide plate. The die head can continuously perform stamping and flanging without waiting, and the stamping and flanging efficiency is higher, solving the problems proposed in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A safe and efficient automatic bearing flanging machine, including a base and a turntable. The turntable is rotatably installed at the middle position on the surface of the base through a rotating shaft. A plurality of dies are evenly embedded and fixed on the surface of the turntable. An upper plate is supported and fixed on the base. A vertical rod is vertically fixed below the upper plate on the side of the turntable. A guide cylinder is fixed on the lower side of the vertical rod. The bottom of the guide cylinder is close to the upper side of the die, and a hopper communicating with it is connected above the guide cylinder. A hydraulic cylinder is vertically installed above the upper plate on the other side of the turntable.

[0006] By adopting the above technical solution, the conveyor belt continuously transfers the bearing to the position above the hopper, and the bearing can be guided to the die groove of the mold through the hopper and the guide tube. The die groove is driven by the turntable to rotate continuously, so that the bearing raw materials can be quickly put into different die grooves, and then they are rotated one by one to the bottom of the die head, and are punched and flanged by it. After that, the bearing can be adsorbed and lifted by magnetic attraction and finally collected through the guide plate.

[0007] Optionally, a stepper motor is installed below the base in the middle of the turntable, and the rotating shaft of the turntable is transmission-connected to the stepper motor.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Please refer to Figure 1-2 , the present utility model provides a technical solution: a safe and efficient bearing automatic flanging machine, including a base 1 and a turntable 2. Four corners at the bottom of the base 1 are supported and fixed with support feet. There are at least four support feet, and the heights of the support feet are the same, so as to realize the horizontal support of the base 1.

[0023] A groove is arranged at the middle position on the surface of the base 1, so that the turntable 2 is rotatably installed in the groove at the middle position on the surface of the base 1 through a rotating shaft. And the upper surface height of the turntable 2 is at the same height as the surface height of the base 1. A plurality of fixing grooves 21 are evenly arranged on the outer ring of the surface of the turntable 2. The mold 211 is evenly embedded and fixed inside the surface of the turntable 2 through the fixing grooves 21 on the surface of the turntable 2, and the upper surface of the mold 211 is flush with the surface of the turntable 2.

[0024] The upper plate 3 is supported and fixed on the base 1. A vertical rod 6 is vertically fixed below the upper plate 3 on the side of the turntable 2. A guide cylinder 61 is fixed on the lower side of the vertical rod 6. The bottom of the guide cylinder 61 is close to the upper part of the mold 211. A hopper 611 connected and communicated with the guide cylinder 61 is arranged above the guide cylinder 61. The conveyor belt for the transmission bearing can be arranged above the right side of the guide cylinder 61. Thus, the bearing can be gradually inserted into the left side and fall into the hopper 611, and then fall from the guide cylinder 61 and fall into the mold cavity of the mold 211 directly below. A stepping motor 22 is installed below the base 1 at the middle position of the turntable 2. The rotating shaft of the turntable 2 is in transmission connection with the stepping motor 22. Then, the stepping motor 22 can drive the turntable 2 to rotate, so that all the molds 211 can be rotated to the lower part of the guide cylinder 61, and thus bearings can be put into the molds 211.

[0025] A hydraulic cylinder 4 is vertically installed above the upper plate 3 on the other side of the turntable 2. The hydraulic cylinder 4 is driven by a hydraulic workstation. The extending end of the hydraulic cylinder 4 is fixed with a die head 41 positioned directly above the mold 211. A plurality of electromagnets 411 are evenly fixed on the surface of the die head 41. When the mold 211 containing the bearing rotates to directly below the die head 41, the hydraulic cylinder 4 can be started to drive the die head 41 to lower its height, so as to realize the stamping and flanging of the bearing. Subsequently, when the die head 41 is driven to rise in height, the electromagnets 411 are energized to be magnetic, and can suck up the stamped and flanged bearing and take it out.

[0026] Circular grooves 71 are respectively formed in a surrounding manner on the outer circumference below the turntable 2 and on the surface of the base 1 below it. A plurality of balls 7 are evenly and rollably supported between the circular grooves 71 of the turntable 2 and the base 1. When the die head 41 drives the bearing in the mold 211 to be stamped and flanged, the balls 7 realize the stable support for the outer ring of the turntable 2, avoiding the turntable 2 being subjected to a large acting force and transmitted to the rotating shaft of the stepping motor 22 to cause its damage.

[0027] A push rod 52 is horizontally installed above the base 1 on the side of the hydraulic cylinder 4. The upper part of the push rod 52 is fixed with an inclined guide plate 5 through a lower plate 51. The guide plate 5 is inclined to the left. When the die head 41 drives the bearing to a height higher than the right side of the guide plate 5, the push rod 52 is controlled to drive the guide plate 5 to move to the right, so that the electromagnets 411 are powered off and lose magnetism, and the bearing falls and is then guided to roll to the left and finally collected. Then, the push rod 52 drives the guide plate 5 to reset, and then the continuous stamping and flanging operation is continued.

[0028] During use, the control terminals of the stepping motor 22, the electromagnet 411, the electric push rod 52, and the hydraulic cylinder 4 are all connected to the control device, so that the conveyor belt of the conveying bearing is horizontally placed above the right side of the hopper 611, and the bearing raw materials can be conveyed from the right side to the left side to the position above the hopper 611. After the bearing raw materials are conveyed and fall to the left, they fall into the mold cavity of the lower mold 211 through the guidance of the hopper 611 and the guide cylinder 61. Then, the stepping motor 22 drives the turntable 2 to rotate instantaneously, rotates the next mold 211 to the directly below the guide cylinder 61, and then continues to drop bearings into the mold cavities of the subsequent molds 211. When the mold 211 containing the bearing rotates to the directly below the die head 41, the hydraulic cylinder 4 is activated to drive the die head 41 to lower its height, so as to perform stamping and flanging on the bearing. Subsequently, the electromagnet 411 is energized, and the bearing after stamping and flanging can be adsorbed and tightly attached to the lower part of the die head 41. Then, as the die head 41 is driven by the hydraulic cylinder 4 to rise in height, during the rising process, the stepping motor 22 continues to drive the turntable 2 to rotate to transfer the new mold 211 containing the bearing to the below of the die head 41, and at the same time, continues to introduce bearings into the mold 211 through the hopper 611 and the guide cylinder 61. When the die head 41 rises to a height greater than the height of the right side of the guide plate 5, the electric push rod 52 drives the guide plate 5 to displace to the right so that the upper right side is placed below the die head 41. Then, the electromagnet 411 is powered off and loses magnetism, no longer adsorbing the bearing and causing it to fall onto the surface of the guide plate 5, and then being guided and conveyed to the left, and finally falling into the collection device arranged below the left guide plate 5. Then, the electric push rod 52 drives the guide plate 5 to displace to the left to reset, and then the automatic stamping and flanging processing of the bearing can be continued.
