Technical Field

[0001] The utility model relates to the technical field of steel ball production, in particular to a steel ball blank cutting machine. Background Art

[0002] When cutting steel ball blanks, traditional cutting machines are unable to fix the front and rear ends of the cutting part of the blank. Most steel ball blanks are round steel forgings, which have no fixed front and rear ends. Round steel forgings will move under the action of cutting force, resulting in uneven cutting surfaces, which will cause great trouble to the subsequent grinding process and reduce the final quality of the steel ball.

[0003] Therefore, in order to solve the defect of the cutting machine lacking a corresponding fixing mechanism before and after the cutting end, it is necessary to propose a steel ball blank cutting machine. Utility Model Content

[0019] See also Figure 1-Figure 3 A steel ball blank cutting machine includes a body 1, which is composed of a feeding end 101 and a cutting end 102. The cutting end 102 is provided with a stand 11, a stand 2 12 and a material guide table 13.

[0020] It should be noted that the material guide platform 13 is located at the end of the cutting end 102 and guides the cut steel ball blank so that it can be discharged smoothly in a predetermined direction.

[0021] In order to solve the technical problem of how to feed the steel ball blank to the cutting machine, please refer to Figure 1-Figure 2 , this embodiment provides the following technical solutions:

[0022] The feeding end 101 includes a plurality of rotatably arranged feeding rollers 1011 , and adjacent feeding rollers 1011 are connected via sprockets and chains. One end of one of the feeding rollers 1011 is fixedly connected to a motor.

[0023] Specifically, when the motor is started, the feed roller 1011 connected to it starts to rotate. Since the adjacent feed rollers 1011 are connected through sprockets and chains, the power is transmitted to the adjacent feed rollers 1011 through the transmission action of the sprockets and chains, so that the adjacent feed rollers 1011 rotate at the same speed and direction. In this way, multiple feed rollers 1011 work together, relying on the friction between the surface of the feed roller 1011 and the steel ball blank, to drive the steel ball blank to move forward on the feed roller 1011, thereby achieving the purpose of stably and continuously conveying the steel ball blank to the cutting end 102.

[0024] In order to solve the technical problem of how the cutting machine cuts the steel ball blank, please refer to Figure 1-Figure 3 , this embodiment provides the following technical solutions:

[0025] The second stand 12 is slidably arranged at the upper end of the cutting end 102 through a slide groove 1021. A screw 1022 is rotatably provided in the slide groove 1021. The second stand 12 is threadedly connected to the screw 1022. The screw 1022 is engaged with a driving shaft 1023 through a bevel gear. One end of the driving shaft 1023 is fixedly connected to a motor.

[0026] A hydraulic cylinder 121 is fixedly installed on the top of the vertical frame 12, and the output end of the hydraulic cylinder 121 is fixedly connected to the tool holder 122. The left and right ends of the tool holder 122 form a sliding connection with the vertical frame 12. A cutting knife 123 is movably installed in the tool holder 122, and one end of the knife shaft of the cutting knife 123 is fixedly connected to the motor.

[0027] The vertical frame 11 is welded to the cutting end 102 , and a hydraulic cylinder 111 is fixedly installed on its top. The output end of the hydraulic cylinder 111 is fixedly connected to a baffle plate 112 , and the left and right ends of the baffle plate 112 form a sliding connection with the vertical frame 11 .

[0028] Specifically, start the hydraulic cylinder 111 to drive the baffle plate 112 to move downward, which has a preliminary blocking and positioning effect on the steel ball blank, and then place the steel ball blank on the feed roller 1011 for transportation until the front end of the blank is against the baffle plate 112, and then adjust the position of the stand 12 according to the size to be cut, start the motor, and drive the active shaft 1023 to rotate. Under the engagement of the bevel gear, the active shaft 1023 drives the screw 1022 to rotate. Since the stand 12 is threadedly connected to the screw 1022, and the stand 12 is slidingly connected to the slide 1021, the stand 12 can drive the cutting knife 123 to move. After moving to the appropriate position, start the motor to drive the cutting knife 123 to rotate, and finally start the hydraulic cylinder 2 121, and its output end pushes the knife holder 122 to move downward, so that the rotating cutting knife 123 gradually approaches and contacts the fixed steel ball blank until the cutting is completed.

[0029] In order to solve the technical problem of how the cutting machine fixes the front and rear ends of the steel ball blank, please refer to Figure 3 , this embodiment provides the following technical solutions:

[0030] The second stand 12 is equipped with an electric push rod 125 through a mounting plate 124. The output end of the electric push rod 125 is fixedly connected to a fixed block 126 for clamping the steel ball blank. The fixed block 126 is arranged in the front, back, left and right directions of the second stand 12, and a ball 127 is movably installed at the bottom.

[0031] Specifically, the electric push rod 125 is started, and the electric push rod 125 drives the fixed block 126 to move until the clamping end of the fixed block 126 is tightly fitted with the surface of the blank. In this way, the steel ball blank is tightly clamped from the front and rear ends of the cutting part, thereby fixing the steel ball blank. This fixing method can effectively prevent the steel ball blank from being displaced due to the cutting force during the cutting process, thereby ensuring the stability of the cutting operation and the flatness of the cutting surface.

[0032] It should be noted that the provision of the balls 127 helps to reduce the friction between the lower surface of the fixing block 126 and the surface of the cutting end 102 , thereby facilitating the movement of the fixing block 126 .

[0033] Working principle: Before cutting, the steel ball blank cutting machine can start the electric push rod 125, and the electric push rod 125 drives the fixed block 126 to move until the clamping end of the fixed block 126 is tightly fitted with the blank surface. In this way, the steel ball blank is tightly clamped from the front and rear ends of the cutting part, thereby fixing the steel ball blank. This fixing method can effectively prevent the steel ball blank from being displaced due to the cutting force during the cutting process, thereby ensuring the stability of the cutting operation and the flatness of the cutting surface.
