The sizing mechanism contains a seamless steel pipe. A support frame is fixedly installed on one side of the sizing mechanism. An mounting frame is fixedly installed on the top of the support frame. A support block is slidably installed on the top of the mounting frame. A driving assembly is installed on the top of the mounting frame. A clamping assembly is installed on the top of the support block. A control assembly is installed between the mounting frame and the driving assembly. A storage box is fixedly installed on the top of the support frame.

[0007] The drive assembly includes a lead screw, a screw hole, and a drive motor. The lead screw is movably installed inside the mounting bracket. The screw hole is opened inside the support block and corresponds to the lead screw. The drive motor is fixedly installed on one side of the mounting bracket, and the lead screw is fixedly installed at the output end of the drive motor.

[0008] Furthermore, the clamping assembly includes a housing, a slide groove, a first spring, a slider, a connecting rod, a movable shaft, and a clamping block. The housing is fixedly connected to the top of the support block. The slide groove has three ring-shaped openings inside the housing. The first spring is movably installed inside the slide groove. The slider is slidably installed inside the slide groove and connected to the first spring. The connecting rod is movably installed at the end of the slider away from the first spring. The movable shaft is fixedly connected to the inside of the housing. The connecting rod is movably sleeved on the movable shaft. The clamping block is fixedly connected to the end of the connecting rod away from the slider.

[0009] Furthermore, the control component includes an air passage, an air chamber, a second spring, a first sphere, an air outlet pipe, a third spring, and a second sphere. The air passage is located inside the outer casing, the air chamber is located inside the outer casing, the three first springs communicate with the air chamber, the air passage communicates with the air chamber, the second spring is fixedly installed inside the air passage, the first sphere is fixedly connected to the front end of the second spring, the front end of the first sphere is located outside the outer casing, the air outlet pipe is fixedly connected to the rear end of the outer casing and communicates with the air chamber, the third spring is fixedly installed inside the air outlet pipe, and the second sphere is fixedly connected to the front end of the third spring.

[0010] Furthermore, the control assembly also includes a first support rod, a mounting tube, a crossbar, a second support rod, and a push rod. The first support rod is fixedly connected to the top of the mounting frame near the sizing mechanism. The mounting tube is fixedly installed on the top of the first support rod. A crossbar is fixedly connected inside the first support rod. The second support rod is fixedly connected to the top of the mounting frame away from the first support rod. The push rod is fixedly connected to the top of the second support rod.

[0011] Furthermore, a door is movably installed on the outer wall of the storage box, a hinge is installed between the storage box and the door, a latch is movably installed on the outer wall of the storage box, and a locking block is fixedly connected to the outer wall of the door, with the latch and the locking block corresponding to each other.

[0012] Furthermore, an inclined plate is fixedly installed on the top of the support frame, and the inclined plate is located between the mounting frame and the storage box.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model includes a sizing mechanism, a mounting frame, a support block, a drive assembly, a clamping assembly, a housing, a slide groove, a first spring, a slider, a connecting rod, a movable shaft, a clamping block, a control assembly, an air passage, an air chamber, a second spring, a first ball, and a second support rod. During operation, the seamless steel pipe is drawn in the sizing mechanism and extends from the discharge end. The drive assembly then moves the support block on the mounting frame. When the support block moves the clamping assembly to the front end of the mounting frame, the first ball aligns with the crossbar. Gas enters the air chamber through the mounting pipe and air passage. The gas pressure pushes the first ball to compress the second spring, keeping the air passage unobstructed. After the gas enters the air chamber, the pressure inside increases, pushing the slider to slide within the slide groove, compressing the first spring. Then, the connecting rod rotates around the movable shaft, causing the three clamping blocks to squeeze and clamp the seamless steel pipe. This utility model can automatically clamp steel pipes at designated positions, improving the continuity and stability of the production process. Furthermore, it can accommodate seamless steel pipes of different sizes.

[0015] Compared with existing technologies, this invention, by setting up a mounting frame, support block, drive assembly, clamping assembly, first spring, slider, clamping block, air chamber, air outlet pipe, second ball, push rod, storage box, and inclined plate, achieves automatic unloading, greatly improving production efficiency and reducing labor intensity; it also avoids damage to the steel pipe that may be caused by manual unloading. When the steel pipe is moved to the designated position for unloading, the support block moves the clamping assembly to the rear end of the mounting frame. At this time, the push rod pushes the second ball to expel air from the air outlet pipe, reducing the pressure in the air chamber. The first spring pushes the slider to reset, the clamping block releases the steel pipe, and the steel pipe falls onto the inclined plate. Because the inclined plate is tilted, the steel pipe slides down the inclined plate under the action of gravity and enters the storage box. This invention can achieve automatic unloading, greatly improving production efficiency and reducing labor intensity; at the same time, it can avoid the damage to the steel pipe that may be caused by manual unloading.

[0030] Reference Figure 1-8 The present invention provides an automatic feeding seamless steel pipe drawing machine according to an embodiment of the present invention. The automatic feeding seamless steel pipe drawing machine includes a sizing mechanism 1, inside which is a seamless steel pipe 2. A support frame 3 is fixedly installed on one side of the sizing mechanism 1, and a mounting frame 4 is fixedly installed on the top of the support frame 3. A support block 5 is slidably installed on the top of the mounting frame 4, a drive assembly 6 is installed on the top of the mounting frame 4, a clamping assembly 7 is installed on the top of the support block 5, a control assembly 8 is installed between the mounting frame 4 and the drive assembly 6, and a storage box 9 is fixedly installed on the top of the support frame 3. The drive assembly 6 includes a lead screw 601, a screw hole 602, and a drive motor 603. The lead screw 601 is movably installed inside the mounting frame 4, the screw hole 602 is opened inside the support block 5 and corresponds to the lead screw 601, the drive motor 603 is fixedly installed on one side of the mounting frame 4, and the lead screw 601 is fixedly installed at the output end of the drive motor 603.

[0031] After the drive motor 603 starts, the output end of the drive motor 603 drives the lead screw 601 to rotate. Since the screw hole 602 on the support block 5 cooperates with the lead screw 601, and the support block 5 is slidably installed on the top of the mounting frame 4, the rotation of the lead screw 601 will drive the support block 5 to move on the mounting frame 4. After the seamless steel pipe 2 is pulled in the sizing mechanism 1, the drive assembly 6 drives the support block 5 to move, thereby driving the clamping assembly 7 and the clamped seamless steel pipe 2 to move.

[0032] The clamping assembly 7 includes a housing 701, a slide groove 702, a first spring 703, a slider 704, a connecting rod 705, a movable shaft 706, and a clamping block 707. The housing 701 is fixedly connected to the top of the support block 5. The slide groove 702 has three ring-shaped openings inside the housing 701. The first spring 703 is movably installed inside the slide groove 702. The slider 704 is slidably installed inside the slide groove 702 and connected to the first spring 703. The connecting rod 705 is movably installed at the end of the slider 704 away from the first spring 703. The movable shaft 706 is fixedly connected to the inside of the housing 701. The connecting rod 705 is movably sleeved on the movable shaft 706. The clamping block 707 is fixedly connected to the end of the connecting rod 705 away from the slider 704.

[0033] In use, in the initial state, the first spring 703 is in a natural state, and the slider 704 is located at one end of the groove 702. When the seamless steel pipe 2 extends from the discharge end of the sizing mechanism 1, the slider 704 slides in the groove 702, compressing the first spring 703. Then, the connecting rod 705 rotates around the movable shaft 706 by rotating the angle. Then, the three clamping blocks 707 squeeze the steel pipe and clamp the seamless steel pipe 2.

[0034] The control component 8 includes an air passage 801, an air chamber 802, a second spring 803, a first sphere 804, an air outlet pipe 805, a third spring 806, and a second sphere 807. The air passage 801 is located inside the outer casing 701, and the air chamber 802 is located inside the outer casing 701. The three first springs 703 are connected to the air chamber 802, and the air passage 801 is connected to the air chamber 802. The second spring 803 is fixedly installed inside the air passage 801. The first sphere 804 is fixedly connected to the front end of the second spring 803, and the front end of the first sphere 804 is located outside the outer casing 701. The air outlet pipe 805 is fixedly connected to the rear end of the outer casing 701 and is connected to the air chamber 802. The third spring 806 is fixedly installed inside the air outlet pipe 805, and the second sphere 807 is fixedly connected to the front end of the third spring 806.

[0035] When the steel pipe needs to be clamped, external gas enters the air chamber 802 through the air passage 801. The pressure of the gas pushes the first ball 804 to compress the second spring 803, keeping the air passage 801 unobstructed. After the gas enters the air chamber 802, the pressure inside the air chamber 802 increases, pushing the slider 704 to slide in the groove 702, thereby clamping the steel pipe with the clamping block 707. When the steel pipe needs to be released, the second ball 807 is pushed to exhaust the air through the air outlet 805, reducing the pressure inside the air chamber 802. The first spring 703 then pushes the slider 704 to reset.

[0036] The control assembly 8 also includes a first support rod 808, a mounting tube 809, a crossbar 810, a second support rod 811, and a push rod 812. The first support rod 808 is fixedly connected to the top of the mounting frame 4 near the end of the sizing mechanism 1. The mounting tube 809 is fixedly installed on the top of the first support rod 808. The crossbar 810 is fixedly connected inside the first support rod 808. The second support rod 811 is fixedly connected to the top of the mounting frame 4 away from the first support rod 808. The push rod 812 is fixedly connected to the top of the second support rod 811.

[0037] The mounting tube 809 is used to connect to an external air pipe. When the support block 5 moves the clamping assembly 7 to the front end of the mounting frame 4, the first ball 804 corresponds to the position of the crossbar 810, and the gas in the mounting tube 809 can enter the air passage 801. When the clamping assembly 7 reaches the rear end of the mounting frame 4, the push rod 812 will push the second ball 807 to exhaust the air from the air outlet 805, thereby achieving precise control of the gas, ensuring the accuracy and timeliness of the clamping and releasing operations, and enhancing the stability of this utility model.

[0038] A door stop 901 is movably installed on the outer wall of the storage box 9. A hinge 902 is installed between the storage box 9 and the door stop 901. A latch 903 is movably installed on the outer wall of the storage box 9. A locking block 904 is fixedly connected to the outer wall of the door stop 901. The latch 903 and the locking block 904 correspond to each other.

[0039] The door 901 can be connected to the storage box 9 via the hinge 902, and the door 901 can be fixed or opened via the latch 903 and the locking block 904, which facilitates the storage and retrieval of the drawn seamless steel pipe 2 and ensures the safe and neat storage of the steel pipe.

[0040] An inclined plate 10 is fixedly installed on the top of the support frame 3, and the inclined plate 10 is located between the mounting frame 4 and the storage box 9.

[0041] When the clamping component 7 releases the steel pipe, the steel pipe will fall onto the inclined plate 10. Since the inclined plate 10 is tilted, the steel pipe will slide down the inclined plate 10 under the action of gravity and enter the storage box 9.

[0042] Working principle: During operation, the seamless steel pipe 2 is drawn out from the discharge end after being drawn in the sizing mechanism 1.

[0043] Then, the drive motor 603 starts, driving the lead screw 601 to rotate. Since the screw hole 602 on the support block 5 cooperates with the lead screw 601, and the support block 5 is slidably mounted on the top of the mounting bracket 4, the rotation of the lead screw 601 will drive the support block 5 to move on the mounting bracket 4.

[0044] When the support block 5 moves the clamping assembly 7 to the front end of the mounting frame 4, the first ball 804 corresponds to the position of the crossbar 810. Gas enters the air chamber 802 through the mounting pipe 809 and the air passage 801. The pressure of the gas pushes the first ball 804 to compress the second spring 803, keeping the air passage 801 unobstructed. After the gas enters the air chamber 802, the pressure inside the air chamber 802 increases, pushing the slider 704 to slide in the slide groove 702, compressing the first spring 703. Then, the connecting rod 705 rotates around the movable shaft 706 by rotating the angle. Then, the three clamping blocks 707 squeeze the steel pipe and clamp the seamless steel pipe 2.

[0045] Then, the drive component 6 moves the steel pipe to the designated position. When the material needs to be unloaded, the support block 5 moves the clamping component 7 to the rear end of the mounting frame 4. At this time, the push rod 812 pushes the second ball 807 to exhaust the air pipe 805. The pressure in the air chamber 802 decreases, the first spring 703 pushes the slider 704 to reset, the clamping block 707 releases the steel pipe, and the steel pipe falls on the inclined plate 10. Since the inclined plate 10 is inclined, the steel pipe slides down the inclined plate 10 under the action of gravity and enters the storage box 9.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
