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.
[0033] like Figures 1 to 8 As shown, the utility model provides a tube shrinking machine with a claw mechanism for furniture production, comprising:
[0034] A base 1, a bracket 2 is fixedly installed on the top of the middle of the left end of the base 1, a horizontal plate 3 is fixedly installed on the top of the bracket 2, and a claw feeder 22 located behind the horizontal plate 3 is fixedly installed on the left side of the top of the base 1;
[0035] An adjusting mechanism 4, wherein the adjusting mechanism 4 is arranged at the top of the horizontal plate 3;
[0036] A pushing mechanism 5, which is arranged at the bottom end of the horizontal plate 3;
[0037] Among them, the adjustment mechanism 4 includes a slide groove 401, which is opened at the bottom end of the cross plate 3, and sliders 402 are movably sleeved on the left and right sides of the middle end of the slide groove 401. There are two sliders 402. Connecting rods 403 are fixedly installed on the bottom ends of the two sliders 402. There are two connecting rods 403. The tops of the two connecting rods 403 are movably connected to the bottom end of the cross plate 3. L-shaped rods 404 are fixedly installed on the opposite backs of the two connecting rods 403. There are two L-shaped rods 404. The outer surfaces of the two L-shaped rods 404 are movably connected to the outer surface of the cross plate 3. Guide plates 405 are fixedly installed on the opposite surfaces of the two L-shaped rods 404. There are two guide plates 405. The bottom ends of the two guide plates 405 are movably connected to the top of the cross plate 3, and the connecting rods 403 will move the guide plates 405.
[0038] When the two connecting rods 403 are pushed, they will carry the L-shaped rod 404 to move in opposite directions along the outer surface of the horizontal plate 3. At this time, the guide plate 405 fixedly connected to the L-shaped rod 404 will move together, so that the distance between the two guide plates 405 can be automatically adjusted. The existence of the slide groove 401 and the slider 402 will limit the movement of the connecting rod 403.

[0043] When the pneumatic cylinder 501 is activated, the rectangular block 502 will move along the outer surface of the horizontal plate 3 with the connecting rod 503, so that the connecting rod 503 generates a thrust on the connecting rod 403, pushing the two connecting rods 403 to move away from each other.
[0044] Among them, a fixed block 6 is fixedly installed on the left side of the top of the base 1, a static clamp 7 is fixedly installed on the right end of the fixed block 6, a stopper 8 is fixedly installed on the left end of the fixed block 6, and the left side of the bottom end of the stopper 8 and the right side of the top of the cross plate 3 are movably connected.
[0045] The existence of the stopper 8 will block the steel pipe, thereby preventing the steel pipe from detaching from the transverse plate 3 .
[0046] Among them, a limit plate 9 located on the right side of the static clamp 7 is fixedly installed on the right side of the top of the base 1, and a dynamic clamp 10 is movably sleeved on the right end of the limit plate 9. A first support block 11 is movably installed on the right end of the limit plate 9. The bottom end of the first support block 11 is fixedly connected to the top of the base 1, and a clamping cylinder 12 is fixedly installed on the right end of the first support block 11. The left end of the clamping cylinder 12 passes through the first support block 11 and extends to the outside of the first support block 11 and is fixedly connected to the right end of the dynamic clamp 10.
[0047] When the clamping oil cylinder 12 is started, the dynamic clamp 10 will move to the left along the inner surface of the limit plate 9, thereby cooperating with the static clamp 7 to clamp the steel pipe.
[0048] Among them, the left and right sides of the top of the base 1 are respectively movably connected with mounting blocks 13, the right end of the mounting block 13 is fixedly installed with a mold 14, the left end of the mounting block 13 is movably connected with a second support block 15, the bottom end of the second support block 15 is fixedly connected to the top of the base 1, the left end of the second support block 15 is fixedly installed with a main cylinder 16, the right end of the main cylinder 16 penetrates the second support block 15 and extends to the outside of the second support block 15 and is fixedly connected to the left end of the mounting block 13.
[0049] When the main oil cylinder 16 is started, the mounting block 13 will move with the mold 14, thereby performing a tube shrinking operation on the steel tube.
[0050] Among them, a round rod 17 is fixedly sleeved at the bottom end of the base 1, and a buffer plate 18 is movably sleeved on the outer surface of the round rod 17. The outer surface of the buffer plate 18 is movably sleeved with the inner surface of the base 1, and springs 19 are fixedly installed on the upper and lower ends of the left side of the front end of the buffer plate 18. The other end of the spring 19 is fixedly connected to the left inner wall of the base 1, and the spring 19 will reset the buffer plate 18.
[0051] Due to the presence of the buffer plate 18 and the spring 19, when the processed steel pipe falls to the top of the buffer plate 18, the buffer plate 18 will rotate around the round rod 17 and compress the spring 19. Under the restoring action of the spring 19, the buffer plate 18 will be forced to return to its original position, thereby buffering the steel pipe.
[0052] An arc groove 20 is provided on the right side of the inner wall at the bottom of the base 1 , and a long rod 21 is movably sleeved at the rear end of the arc groove 20 , and the outer surface of the long rod 21 is fixedly sleeved with the inner surface of the right end of the buffer plate 18 .
[0053] The inner surface of the arc groove 20 and the outer surface of the long rod 21 are both smooth, ensuring that the long rod 21 will not get stuck when moving along the inside of the arc groove 20.
[0054] The working principle and use process of this utility model:
[0055] First, the operator activates the pneumatic cylinder 501 according to the length of the steel pipe, so that the rectangular block 502 moves, so that the connecting rod 503 hinged to the rectangular block 502 moves together, and then the other end of the connecting rod 503 generates a thrust on the connecting rod 403, pushing the two connecting rods 403 through the L-shaped rod 404 and carrying the guide plate 405 along the outer surface of the cross plate 3 to move in opposite directions until the spacing between the two guide plates 405 is equal to the length of the steel pipe. Then the operator places the steel pipe between the two guide plates 405, and then Start the claw feeder 22 so that it clamps the steel pipe and transports it between the static clamp 7 and the dynamic clamp 10. Then start the clamping cylinder 12 so that it pushes the dynamic clamp 10 to move along the inner surface of the limit plate 9 to cooperate with the static clamp 7 to clamp the steel pipe. Then start the claw feeder 22 again to reset it. Then start the main cylinder 16 to shrink the steel pipe through the mold 14. The cooperation of various mechanisms realizes the automatic adjustment of the spacing of the guide plates 405, thereby improving the convenience of the shrinking machine.
[0056] After the processing of the steel pipe is completed, the operator starts the clamping cylinder 12 to loosen the clamp on the steel pipe. At this time, the steel pipe will naturally fall to the top of the buffer plate 18, thereby generating a downward force on the buffer plate 18, so that the buffer plate 18 rotates with the long rod 21 along the inner surface of the arc groove 20 with the round rod 17 as the axis and compresses the spring 19 until the steel pipe slides out of the buffer plate 18. Under the restoring action of the spring 19, the buffer plate 18 will return to its original position, thereby achieving buffering when the steel pipe falls, thereby preventing the steel pipe from falling too fast and generating a large impact force to cause damage to the steel pipe.
[0057] 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.
