Description

Technical Field

[0001] The present invention relates to the technical field of cylinder liner forging, and more particularly to a cylinder liner forging device. Background Art

[0002] There are many types of cylinder liner forging equipment, depending on the size, material, precision requirements and production scale of the cylinder liner.

[0003] Among them, in the forging process of the cylinder liner, it is necessary to heat the workpiece to be processed, and then impact the middle of the heated workpiece to form a hollow part inside the cylinder liner. During this process, the hammer head needs to be placed on the cylinder liner and hammered continuously to move the hammer head inside the cylinder liner and leave a hollow channel in the middle of the cylinder liner. After one end of the material to be processed is hammered, the workpiece to be processed needs to be flipped 180 degrees, and then impacted again from the other end, so that the channels hammered twice before and after are connected together, thereby forming a preliminary model of the cylinder liner.

[0004] When the workers turn over the workpiece to be processed, since the workpiece used to be processed into the cylinder liner is made of metal, when the larger cylinder liner is turned over by the workers, it is not only difficult to turn over, but also easy to cause the cylinder liner to fall off the anvil. The cylinder liner after rolling down is still in a high temperature state, which is easy to cause safety hazards to surrounding workers. Traditional cylinder liner forging equipment cannot automatically turn over the material to be processed into the cylinder liner after the forging of one end channel of the cylinder liner is completed. Therefore, the present invention discloses a cylinder liner forging equipment. Summary of the Invention

When the movable seat 301 and the rotating seat 302 are collided, the hammer head 303 can be lowered to impact the heated cylinder liner. When the rotating seat 302 rotates, the extension rod 306 can be driven to revolve through the sleeve rod 307. After the rotating seat 302 revolves, the hammer heads 303 of different sizes can be located at the bottom, so that the cylinder liner can be hammered using the hammer heads 303 of different sizes.

[0041] A flip assembly 4 is installed inside the lower side of the fixing frame 101. The flip assembly 4 is used to flip the cylinder liner. The flip assembly 4 includes a rotating plate 401. A sliding groove 402 is formed at the end of the rotating plate 401 away from the fixing frame 101. A clamping assembly 5 for clamping the cylinder liner is installed inside the sliding groove 402.

[0045] By adopting the above technical solution, when the cylinder sleeve rotates, the lower end of the cylinder sleeve can squeeze the load-bearing plate 103, causing it to drop a certain distance and deform the support spring 104. When the cylinder sleeve is separated from the load-bearing plate 103, the load-bearing plate 103 will rise to the highest point. When the load-bearing plate 103 rotates a certain angle, the side wall of the cylinder sleeve can squeeze the load-bearing plate 103, thereby causing the load-bearing plate 103 to drop again until the cylinder sleeve flips one hundred and eighty degrees and then controls the first drive motor 503 to make the clamping rod 501 loosen the cylinder sleeve. When the cylinder sleeve is placed on the load-bearing plate 103, the upper end of the load-bearing plate 103 is aligned with the upper end of the anvil 1.

[0047] By adopting the above technical solution, when the movable seat 301 descends, the driving rod 304 can be driven to descend, and the descending driving rod 304 can drive the elastic pawl 305 to descend. During the descending process of the elastic pawl 305, it will be blocked by the first gear 403 and will rotate, so that it will not engage with the first gear 403. When the movable seat 301 rises, the driving rod 304 can rise synchronously, and when the driving rod 304 rises, it can drive the elastic pawl 305 to rise. When the elastic pawl 305 rises, it can drive the first gear 403 to rotate, thereby causing the rotating plate 401 to rotate.

[0048] A second gear 312 is rotatably installed inside the movable base 301, and a transmission belt 313 is provided on the outside of the first gear 403 and the second gear 312.

The transmission belt 313 meshes with the second gear 312 through the second meshing teeth 315. The first gear 403 and the second gear 312 have the same size. When the first gear 403 rotates one circle, the second gear 312 is driven to rotate ninety degrees through the transmission belt 313 and the second meshing teeth 315.

[0049] By adopting the above technical solution, when the first gear 403 rotates, it can engage with the first meshing teeth 314, thereby causing the transmission belt 313 to rotate. When the transmission belt 313 rotates for the first time, the second meshing teeth 315 do not engage with the second gear 312. When the transmission belt 313 rotates for the second time, the teeth on the second gear 312 can be squeezed by the second meshing teeth 315, thereby causing the second gear 312 to rotate. When the second gear 312 rotates, it can drive the rotating base 302 to rotate, and the rotating angle of the rotating base 302 is ninety degrees each time.

[0050] A plurality of elastic clamps 316 are slidably installed on one end of the movable seat 301 close to the rotating seat 302.

[0051] By adopting the above technical solution, when the rotating seat 302 rotates ninety degrees, the elastic clamp 316 is aligned with the slot 318. At this time, the elastic clamp 316 can be squeezed into contact with the inner wall of the slot 318 under the action of the connecting spring 317, thereby increasing the friction between the end of the elastic clamp 316 and the slot 318, so that the rotating seat 302 is fixed.

[0052] Two guide grooves 105 are provided on the inner wall of the lower side of the fixed frame 101, and a guide block 106 is slidably installed inside the guide groove 105.

The upper side of the third gear 107 is rotatably connected to the support rod 108, and the upper end of the support rod 108 is rotatably connected to the lower end of the movable base 301.

[0053] By adopting the above technical solution, when the distance between the movable seat 301 and the first gear 403 changes, the movable seat 301 can squeeze the third gear 107 through the support rod 108, so that the third gear 107 moves along the direction of the guide groove 105 under the action of the guide block 106. After the third gear 107 moves, it can squeeze the transmission belt 313, causing the transmission belt 313 to deform, so that the transmission belt 313 can always remain in a taut state.

[0054] The movable base 301 is slidably connected to the fixed frame 101 through a connecting block 319. A mounting base 320 is fixedly mounted on the fixed frame 101.

The output end of the second driving motor 109 is fixedly connected to the winding wheel 321. The second driving motor 109 is used to drive the winding wheel 321 to rotate.

[0055] A cavity 308 is provided inside the rotating seat 302, and the interior of the sleeve rod 307 is connected to the interior of the cavity 308.

The ball 311 moves along the direction of the threaded groove 310.

[0056] By adopting the above technical solution, the second drive motor 109 can drive the winding wheel 321 to rotate, and the winding wheel 321 can wind the pull rope 322 after rotating, so that the connecting block 319 and the movable seat 301 can rise, and the movable seat 301 can drive the rotating seat 302 to rise after rising, thereby rising through the rotating seat 302, the sleeve rod 307, and the extension rod 306. In the process of the rotating seat 302 rising, the sleeve rod 307 can rise. When the sleeve rod 307 rises, due to the friction between the hammer head 303 and the cylinder sleeve, the sleeve rod 307 can When the extension rod 306 moves relative to the sleeve rod 307, the ball 311 can move along the direction of the threaded groove 310, thereby causing the extension rod 306 to rotate. When the extension rod 306 rotates, it can drive the hammer head 303 to rotate. The rotation of the hammer head 303 can break the stuck state between the hammer head 303 and the cylinder sleeve, so that the hammer head 303 can be taken out more easily.
