[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A static cam type front outlet device for a multi-station cold heading machine includes a base, a fixed platform is fixedly connected to the top of the base, a support frame is fixedly connected to the top of the base, a plurality of push holes are opened in the fixed platform, a fixed block is fixedly connected to the inside of the base, a fixed rod 1 is fixedly connected to the inside of the base, a push rocker arm is rotatably connected to the fixed rod 1, a reset assembly is installed on the top of the fixed block, an adjustment assembly is installed on the top of the base, a fixed rod 2 is fixedly connected to the inside of the support frame, and a cam pendulum is rotatably connected to the fixed rod 2.

[0008] By adopting the above technical solution, the adjusting component is first started to push the cam pendulum to swing on the fixed rod two, thereby driving the cam pendulum to fit with the pusher rocker arm. As the cam pendulum gradually swings, the pusher rocker arm is squeezed to rotate on the fixed rod one, so that one end of the pusher rocker arm gradually descends as the roller pushes it. As one end of the pusher rocker arm descends, the other end will gradually tilt up, thereby passing the workpiece inside the pusher hole forward. Subsequently, the adjusting component is controlled to move in the reverse direction, driving the cam pendulum to gradually move away from the pusher rocker arm. Through the rebound reset of the reset component, the pusher rocker arm is driven to swing in the reverse direction, so that one end of the pusher rocker arm is away from the pusher hole and resets, thereby performing a reciprocating push and ejection motion.

[0009] Furthermore, one end of the pusher rocker arm is fixedly connected to the front swing arm, and one end of the pusher rocker arm away from the front swing arm is fixedly connected to the rear swing arm.

[0010] By adopting the above technical solution, the front swing arm can be pushed to swing more conveniently through the rolling contact between the front swing arm and the roller.

A support plate is fixedly connected to the top of the telescopic rod, and the top of the support plate is located at the bottom of one end of the pusher rocker arm.

[0012] By adopting the above technical solution, as the pushing rocker arm gradually swings, one end of the pushing rocker arm fits against the top of the support plate, thereby pushing the telescopic rod to retract.

[0013] Furthermore, a spring is fixedly connected inside the reset groove, the top end of the spring is fixedly connected to the bottom end of the support plate, and the telescopic rod is located inside the spring.

[0014] By adopting the above technical solution, according to the elasticity of the spring, the support plate will be driven to push upward and push the push rocker arm to swing in the opposite direction, so that the push rocker arm can automatically return to its original position after completing the forward movement and wait for the next passage.

[0015] Furthermore, the adjustment component includes grooves symmetrically opened on the top of the base, wherein a threaded rod is rotatably connected inside one of the grooves, a motor is fixedly connected to one side of the base, the output end of the motor is fixedly connected to one end of the threaded rod, and a moving block is threadedly connected to the threaded rod.

[0016] By adopting the above technical solution, the starting motor drives the threaded rod to rotate, and the rotation of the threaded rod drives the moving block to move.

[0017] Furthermore, a guide rod is fixedly connected inside the other groove, a moving block is also slidably connected to the guide rod, and corresponding surfaces of the two moving blocks are fixedly connected to fixed rods three.

[0018] By adopting the above technical solution, when the two moving blocks drive the fixed rod three to move, it will drive the multiple cam pendulums on the fixed rod three to swing with the fixed rod two as the center, thereby pushing the cam pendulums to contact with the push rocker arm to complete the passage.

[0019] Furthermore, one end of the cam rocker is rotatably connected to the fixed rod three, and a connecting groove is provided at one end of the cam rocker away from the fixed rod three. A connecting rod is fixedly connected inside the connecting groove, and a roller is rotatably connected to the connecting rod.

[0020] By adopting the above technical solution, the reciprocating movement of the adjustment component will drive the cam pendulum to swing back and forth, thereby pushing the push rocker arm to pass out.

[0021] Furthermore, there are multiple pusher rocker arms which are equidistantly arranged on the first fixed rod, there are multiple cam rocker members which are equidistantly arranged on the second fixed rod, and the number of the pusher rocker arms is the same as the number of the cam rocker members.

[0022] By adopting the above technical solution, through adjusting the movement of the components separately, multiple cam pendulums are controlled to eject multiple push rocker arms, so that multiple push rocker arms can eject workpieces synchronously and uninterruptedly, thereby improving the synchronization performance of the device and greatly enhancing the practicability of the device.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. The present application is provided with an adjusting component and a cam rocker. First, the adjusting component is started to move back and forth on the base to drive the multiple cam rockers to swing back and forth on the fixed rod 2. The multiple pushing rocker arms are ejected by controlling the multiple cam rockers, so that the multiple pushing rocker arms can eject the workpiece synchronously and uninterruptedly, thereby improving the synchronization performance of the device and greatly enhancing the practicability of the device.

[0025] 2. The present application is provided with a reset component. When one end of the pushing rocker arm gradually descends as pushed by the roller, the reset component will be squeezed to shrink. When the rear swing arm loses the pressure of the roller, the reset component will rebound and reset, driving the pushing rocker arm to swing in the opposite direction. After completing the front-out movement, the pushing rocker arm can automatically reset to its original position and wait for the next outward movement. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a static cam type front-through device for a multi-station cold heading machine.

[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A static cam front-through device for a multi-station cold heading machine includes a base 1, a fixed platform 2 is fixedly connected to the top of the base 1, a support frame 3 is fixedly connected to the top of the base 1, a plurality of push holes 4 are opened in the fixed platform 2, a fixed block 5 is fixedly connected inside the base 1, a fixed rod 1 6 is fixedly connected inside the base 1, a push rocker arm 7 is rotatably connected to the fixed rod 1 6, a reset component 8 is installed on the top of the fixed block 5, an adjustment component 9 is installed on the top of the base 1, a fixed rod 2 10 is fixedly connected inside the support frame 3, a cam pendulum 11 is rotatably connected to the fixed rod 2 10, and a push rocker arm 7 is installed on the top of the fixed block 5. One end is fixedly connected to the front swing arm 71, the end of the pusher rocker arm 7 away from the front swing arm 71 is fixedly connected to the rear swing arm 72, one end of the cam pendulum 11 is rotatably connected to the fixed rod three 96, the end of the cam pendulum 11 away from the fixed rod three 96 is provided with a connecting groove 111, a connecting rod 112 is fixedly connected inside the connecting groove 111, and a roller 113 is rotatably connected to the connecting rod 112, there are multiple pusher rocker arms 7 and they are equidistantly arranged on the fixed rod one 6, there are multiple cam pendulums 11 and they are equidistantly arranged on the fixed rod two 10, and the number of the pusher rocker arms 7 is the same as that of the cam pendulums 11.

[0035] When the device is used, first start the adjustment component 9 to push the cam swing 11 to swing on the fixed rod 10, thereby driving the roller 113 at one end of the cam swing 11 to fit with the front swing arm 71 at one end of the pusher rocker arm 7. Through the rolling contact between the front swing arm 71 and the roller 113, the front swing arm 71 can be pushed to swing more conveniently. As the cam swing 11 gradually swings, the pusher rocker arm 7 is squeezed and rotated on the fixed rod 6, so that the front swing arm 71 gradually descends with the push of the roller 113, and squeezes the reset component 8 to shrink, and the pusher rocker arm 7 is away from the rear swing arm 72 at one end of the front swing arm 71, and tilts as the front swing arm 71 descends. The push assembly 9 is controlled to move in the reverse direction, thereby passing the workpiece in the push hole 4 forward, and then the adjusting component 9 is controlled to move in the reverse direction, driving the roller 113 to gradually move away from the front swing arm 71. When the front swing arm 71 loses the pressure of the roller 113, the rebound reset of the reset component 8 drives the push rocker arm 7 to swing in the reverse direction, so that the rear swing arm 72 is away from the push hole 4 and resets, thereby performing a reciprocating push and ejection motion. By moving the adjusting component 9 alone, the multiple cam pendulums 11 are controlled to eject the multiple push rocker arms 7, so that the multiple push rocker arms 7 can eject the workpiece synchronously and uninterruptedly, thereby improving the synchronization performance of the device and greatly enhancing the practicability of the device.

[0036] Reference Figure 1 and Figure 2 The reset assembly 8 includes a plurality of reset grooves 81 opened on the top of the fixed block 5, and a telescopic rod 82 is fixedly connected inside the plurality of reset grooves 81, and a support plate 83 is fixedly connected to the top of the telescopic rod 82. The top of the support plate 83 is located at the bottom of one end of the pusher rocker arm 7, and a spring 84 is fixedly connected inside the reset groove 81. The top of the spring 84 is fixedly connected to the bottom of the support plate 83, and the telescopic rod 82 is located inside the spring 84.

[0037] When the pushing rocker arm 7 swings, one end of the pushing rocker arm 7 will fit with the top of the support plate 83. As the pushing rocker arm 7 gradually swings, the telescopic rod 82 will be pushed to shrink and the spring 84 will be squeezed to shrink together. When one end of the pushing rocker arm 7 loses pressure, according to the elasticity of the spring 84, the support plate 83 will be driven upward and the pushing rocker arm 7 will be pushed to swing in the opposite direction, so that the pushing rocker arm 7 can automatically return to its original position after completing the forward passage movement and wait for the next passage.

[0038] Reference Figure 1 and Figure 2The adjustment component 9 includes grooves 91 symmetrically opened on the top of the base 1, wherein a threaded rod 92 is rotatably connected inside one of the grooves 91, a motor 93 is fixedly connected to one side of the base 1, an output end of the motor 93 is fixedly connected to one end of the threaded rod 92, a moving block 94 is threadedly connected to the threaded rod 92, a guide rod 95 is fixedly connected inside the other groove 91, and the moving block 94 is also slidably connected to the guide rod 95, and a fixed rod three 96 is fixedly connected to the corresponding surfaces of the two moving blocks 94.

[0039] When the device is used, first start the motor 93 to drive the threaded rod 92 to rotate. The rotation of the threaded rod 92 will drive the moving block 94 to move. Through the support of the fixed rod three 96, the two moving blocks 94 will move together. When the two moving blocks 94 drive the fixed rod three 96 to move, the multiple cam pendulums 11 on the fixed rod three 96 will be driven to swing with the fixed rod two 10 as the center of the circle, thereby pushing the cam pendulum 11 to contact the push rocker arm 7 to complete the passage.

[0040] The implementation principle of the static cam front-through device for a multi-station cold heading machine in this embodiment is as follows: when the device is used, the motor 93 is first started to drive the threaded rod 92 to rotate, and the rotation of the threaded rod 92 drives the moving block 94 to move. Through the support of the fixed rod 3 96, the two moving blocks 94 move together. When the two moving blocks 94 drive the fixed rod 3 96 to move, the multiple cam swing members 11 on the fixed rod 3 96 are driven to swing with the fixed rod 2 10 as the center of the circle. The front swing arm 71 is pushed to move, thereby driving the roller 113 at one end of the cam swing member 11 to fit with the front swing arm 71 at one end of the pusher rocker arm 7. The rolling contact between the front swing arm 71 and the roller 113 can more conveniently push the front swing arm 71 to swing. As the cam swing member 11 gradually swings, the pusher rocker arm 7 is squeezed to rotate on the fixed rod 6, so that the front swing arm 71 gradually descends and fits with the top of the support plate 83 as the roller 113 pushes. As the pusher rocker arm 7 gradually swings, it pushes the telescopic rod 82 to retract. The rear swing arm 72 of the pusher rocker arm 7 is away from the front swing arm 71, and tilts up as the front swing arm 71 descends, so that the workpiece inside the pusher hole 4 is passed forward, and then the motor 93 is controlled to rotate in the opposite direction, so that the fixed rod 3 96 with the two moving blocks 94 moves in the opposite direction, so that the cam swing member 11 swings in the opposite direction on the fixed rod 2 10, and the roller 113 is gradually away from the front swing arm 71. When the front swing arm 71 loses the pressure of the roller 113, according to The elasticity of the spring 84 will drive the support plate 83 to push upward and push the push rocker arm 7 to swing in the opposite direction, so that the rear swing arm 72 can automatically return to its original position after completing the front passing movement, waiting for the next passing, thereby performing a reciprocating push and ejection movement. By independently moving the moving block 94, multiple cam swing members 11 are controlled to eject multiple push rocker arms 7, so that multiple push rocker arms 7 can eject workpieces synchronously and uninterruptedly, thereby improving the synchronization performance of the device and greatly enhancing the practicability of the device.
