[0032] like Figures 1 to 3 As shown, this embodiment proposes:

[0033] A bolt heading machine, comprising:

[0034] The base 1 has a mounting shell 2 fixed on its top wall, a housing 3 fixed on the top of the mounting shell 2, a feed port 9 provided on one side of the housing 3, a discharge port 10 provided on the other side of the housing 3, and a blanking assembly 11 provided on the bottom wall of the housing 3 at a position corresponding to the discharge port 10;

[0035] The feeding tray 4 is rotatably mounted in the mounting shell 2, and a grooved wheel mechanism is installed between the feeding tray 4 and the mounting shell 2;

[0036] A mounting frame 12, a hydraulic cylinder 13 is fixed to the top wall of the mounting frame 12, and a heading mold 14 is fixed to the movable end of the bottom of the hydraulic cylinder 13;

[0037] The bolt vibrating plate 16 has a discharge end connected to the feed port 9 on the housing 3 through a feed pipe 15 .

[0038] In this embodiment, the provided bolt vibration plate 16 is used to introduce the round head bolts to be processed in a uniform state onto the feed plate 4 through the feed pipe 15, and the provided groove wheel mechanism drives the feed plate 4 to move intermittently, so that the round head bolts to be processed are moved at intervals to the heading mold 14 position for the heading operation. At the same time, when the processed round head bolts pass through the discharge port 10 position, the feed plate 4 cooperates with the unloading assembly 11 to push the processed round head bolts from the discharge port 10 position to complete automatic unloading. The overall device has a high degree of automation, simple and convenient operation, and high work efficiency.

[0039] Example 2

[0040] like Figures 3 to 5 As shown, based on the same concept as the above embodiment 1, this embodiment further proposes:

[0041] The feeding tray 4 includes a tray body 41 which is rotatably mounted in the housing 3 . The side walls of the tray body 41 are provided with limiting grooves 42 for placing bolts. A disc 43 is fixed to the bottom wall of the tray body 41 . The side walls of the disc 43 are provided with bumps 44 .

[0042] The sheave mechanism includes an active dial 6, which is rotatably mounted on the top wall of the mounting shell 2. A driven sheave 7 that cooperates with the active dial 6 is fixed to the bottom wall of the disc 43. A round pin 8 is fixed to the active dial 6. A motor 5 is fixed to the top wall of the inner cavity of the mounting shell 2. The power shaft of the motor 5 passes through the top wall of the mounting shell 2 through a bearing and is fixedly connected to the center of the bottom wall of the active dial 6.

[0043] The number of grooves of the driven sheave 7 is the same as the number of the limiting grooves 42 and the protrusions 44 .

[0044] The motor 5 is a stepper motor or a servo motor.

[0045] A mounting shaft is fixed at the bottom axis position of the driven sheave 7 , and the mounting shaft is rotatably mounted on the top wall of the mounting shell 2 .

[0046] In this embodiment, the grooved wheel mechanism is provided to drive the feed tray 4 to move intermittently, so that the round head bolts to be processed are moved to the position of the heading die 14 at intervals for the heading operation. The round head bolts enter the limiting groove 42 through the feed port 9. The disc body 41 cooperates with the housing 3 to limit the round head bolts in the limiting groove 42. At the same time, the motor 5 is controlled to work, and the motor 5 drives the active dial 6 to rotate. The active dial 6 drives the driven grooved wheel 7 to rotate intermittently through the round pin 8. The driven grooved wheel 7 drives the feed tray 4 to rotate intermittently. Every time the feed tray 4 stops moving, there is a limiting groove 42 located below the heading die 14. By controlling the extension of the hydraulic cylinder 13, the heading die 14 is controlled to move downward to perform the heading operation on the round head bolts.

[0047] A chute 113 is defined on the bottom wall of the housing 3 , and the blanking assembly 11 is mounted in the chute 113 .

[0048] The blanking assembly 11 includes an arc-shaped push plate 111 , and a slider 112 is fixed to the middle of the bottom wall of the arc-shaped push plate 111 ;

[0049] The slider 112 is slidably mounted in the slide groove 113 , and a slide shaft 114 is fixed in the slide groove 113 ;

[0050] The sliding shaft 114 slides through the slider 112, and a spring 115 is sleeved on the outer side of the sliding shaft 114;

[0051] The spring 115 is fixed between the slider 112 and the inner wall of the sliding groove 113 .

[0052] In this embodiment, the provided blanking assembly 11 can cooperate with the protrusion 44 on the feed tray 4 to realize automatic blanking of the processed round head bolts. When the protrusion 44 on the feed tray 4 rotates the position of the blanking assembly 11, the protrusion 44 will push the arc-shaped push plate 111 toward the position of the discharge port 10. The arc-shaped push plate 111 will thereby push the processed round head bolts out of the limiting groove 42. The processed round head bolts are collected by the provided collection box. The provided spring 115 can realize the reset of the arc-shaped push plate 111, thereby realizing repeated blanking operations.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
