Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] The preferred embodiment of the precision cold drawing device for roller tubes for agricultural machinery provided by the utility model is as follows Figures 1 to 5As shown: a precision cold drawing device for roller tubes for agricultural machinery, comprising a base 1, a cold drawing die 2 is fixedly connected to the top of the base 1, a conveyor belt 3 fixedly connected to the base 1 at the bottom is arranged on one side of the cold drawing die 2, side plates 4 fixedly connected to the base 1 are rotatably connected on both sides of the conveyor belt 3, mounting plates 5 are fixedly connected to the tops of the two groups of side plates 4, sliders 6 fixedly connected to the tops of the two groups of mounting plates 5 are slidably connected to one side of the slider 6, an electric clamp 7 is fixedly connected to one side of the slider 6, a connecting plate 8 is slidably connected to one side of the base 1, a top plate 9 is fixedly connected to the top of the connecting plate 8, two groups of clamping plates 10 are slidably connected to the top of the top plate 9, an electric push rod 11 fixedly connected to the connecting plate 8 is arranged below the top plate 9, a transmission plate 12 is fixedly connected to the output end of the electric push rod 11, an embedded rod 13 is fixedly connected to the inner side wall of the transmission plate 12, a force-bearing block 14 fixedly connected to the clamping plate 10 is slidably connected to the surface of the embedded rod 13, and a threaded rod 15 rotatably connected to the base 1 is internally threadedly connected to the connecting plate 8.

[0030] In this embodiment, a horizontal straight slide groove is opened on the top of the mounting plate 5, and the slider 6 drives the electric clamp 7 to form a horizontal sliding structure. Under the action of the conveyor belt 3, the slider 6 will slide to the right along the mounting plate 5, and pull the roller through the electric clamp 7 to make it pass through the inside of the cold drawing mold 2.

[0031] In this embodiment, the two sets of clamps 10 are parallel to each other, and the midpoints of the two sets of clamps 10 coincide with the center point of the cold drawing die 2. The clamps 10 slide on the top of the top plate 9 and fit with the rollers to limit their position, making them more stable during transportation.

[0032] In this embodiment, the embedded rod 13 and the transmission plate 12 are arranged perpendicular to each other, and the embedded rod 13 forms a lifting structure through the electric push rod 11. When the electric push rod 11 is opened, it pulls the transmission plate 12 down, and the transmission plate 12 then drives the embedded rod 13 to fall.

[0033] In this embodiment, the embedded rod 13 is connected to the internal inclined groove of the force block 14, and the clamping plate 10 forms a sliding structure along the top of the top plate 9 through the force block 14. When the embedded rod 13 descends, it slides along the internal inclined groove of the force block 14 and applies a thrust to the force block 14. At this time, the force block 14 transmits the thrust to the clamping plate 10.

[0034] In this embodiment, the threaded rod 15 drives the top plate 9 to form a lifting structure along one side of the base 1 by rotating. The threaded rod 15 can be turned to control the lifting of the connecting plate 8, so as to adjust the height of the top plate 9 and achieve the purpose of aligning the roller on the top of the top plate 9 with the cold drawing mold 2.

[0035] In this embodiment, the electric clamp 7 and the discharge port of the cold drawing die 2 are located at the same height. The electric clamp 7 is fixedly connected to the slider 6 through a telescopic cylinder.

[0036] Example 2

[0037] On the basis of Example 1, a preferred embodiment of the precision cold drawing device for roller tubes for agricultural machinery provided by the utility model is as follows: Figures 1 to 5 As shown: two sets of baffles 16 are fixedly connected to both sides of the cold drawing die 2, and a shock absorbing damper 17 is fixedly connected to the inner wall of the base 1.

[0038] In this embodiment, the baffle 16 blocks both ends of the outlet of the cold drawing die 2. By setting the baffle 16, the baffle 16 can prevent debris from being generated when the roller is pulled out from the inside of the cold drawing die 2. The baffle 16 can block the debris to prevent it from splashing.

[0039] In this embodiment, the shock-absorbing damper 17 is arranged horizontally on the inner wall of the base 1. The shock-absorbing damper 17 is in a telescopic state through the base 1. Under the action of the shock-absorbing damper 17, the stability of the overall operation of the device can be improved.

[0040] The working principle and use process of the utility model are as follows: first, the roller to be cold-drawn is placed on the top of the top plate 9. Then, in order to make the clamping plate 10 better limit the roller, the electric push rod 11 can be opened at this time to pull the transmission plate 12 down, and the transmission plate 12 then drives the embedded rod 13 to descend. When the embedded rod 13 descends, it will slide along the internal inclined groove of the force-bearing block 14 and apply a thrust to the force-bearing block 14. At this time, the force-bearing block 14 will transmit the thrust to the clamping plate 10, so that the clamping plate 10 slides on the top of the top plate 9 and fits the roller together, so as to limit it and make it more stable during transportation. Due to the different thicknesses of different rollers, in order to better align them with the cold-drawing die 2, the threaded rod 15 can be twisted to control the lifting and lowering of the connecting plate 8, so as to adjust the height of the top plate 9, so as to achieve the purpose of aligning the roller on the top of the top plate 9 with the cold-drawing die 2;

[0041] Subsequently, the electric clamp 7 is controlled by a cylinder connected to the electric clamp 7 to clamp one end of the roller. Under the action of the conveyor belt 3, the slider 6 slides to the right along the mounting plate 5, and the roller is pulled by the electric clamp 7 to pass through the inside of the cold drawing die 2 to achieve the cold drawing operation. By setting the baffle 16, the baffle 16 can prevent the roller from being pulled out from the inside of the cold drawing die 2. The baffle 16 can block the debris to prevent it from splashing, and under the action of the shock-absorbing damper 17, the overall stability of the equipment during operation can be improved.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
