Description

Technical Field

[0001] This utility model relates to the field of spiral corrugated pipe production technology, and in particular to a spiral corrugated pipe extrusion screw machine. Background Technology

[0002] With the continuous development of society and the continuous progress of science and technology, the technology related to the production of spiral corrugated pipes is also constantly improving. Metal corrugated pipes, as sensitive elements, shock-absorbing elements, compensation elements, sealing elements, valve elements and pipeline connectors, are widely used in automatic control and measuring instruments, vacuum technology, machinery industry, power industry, transportation and nuclear energy industry and other fields.

[0003] The patent document with publication number "CN214516969U" discloses a spiral bellows extrusion screw machine, which includes a bellows body, an inner rod, a fixed claw, a spring, a sleeve, a double-headed motor, a lead screw, a ball nut, a first connecting rod, a pressure roller, and a pressure bar.

[0004] Although the aforementioned patent documents have solved the problems of low efficiency caused by the traditional use of molds in the production of corrugated pipes, the following drawbacks still exist: after processing the spiral corrugated pipe, it is inconvenient to quickly remove the processed spiral corrugated pipe. The manual removal operation is cumbersome, time-consuming and labor-intensive, resulting in low processing efficiency of spiral corrugated pipe. Utility Model Content

[0005] The purpose of this utility model is to solve the following shortcomings in the existing technology: after processing the spiral corrugated pipe, it is inconvenient to quickly remove the processed spiral corrugated pipe. The manual removal operation is cumbersome, time-consuming and labor-intensive, resulting in low processing efficiency of the spiral corrugated pipe. Therefore, a spiral corrugated pipe extrusion screw machine is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A spiral corrugated pipe extrusion screw machine includes a support frame, on which two symmetrically arranged L-shaped blocks are fixedly connected. Each L-shaped block is slidably connected to a slider. A rectangular block is connected inside the slider by a first spring. A clamping component is provided on one side surface of the rectangular block. Each L-shaped block has a groove for the slider to slide back and forth. A reciprocating screw is rotatably connected in the groove. The slider and the reciprocating screw are threaded together. Each L-shaped block is fixedly connected to a limit strip, a hollow housing, and a servo motor. Each hollow housing is provided with a sliding component. Each groove is fixedly connected to a hollow block. The hollow block and the corresponding hollow housing are in communication. A T-shaped plate is connected to one inner wall of the hollow block through a return spring. A guide component is provided on the bracket.

[0007] Preferably, each clamping assembly includes an electric push rod fixedly mounted on one side surface of the rectangular block, and the drive end of the electric push rod is fixedly connected to a fixing block with an isosceles trapezoidal cross-section.

[0008] Preferably, each of the sliding components includes a sealing block slidably installed inside the corresponding hollow housing, a bent rod fixedly connected to one side surface of the sealing block, and a clamping plate fixedly connected to one end of the bent rod.

[0009] Preferably, each of the bent rods is fitted with a second spring, one end of the second spring is fixedly connected to the bent rod, and the other end of the second spring is fixedly connected to the inner wall of the hollow shell.

[0010] Preferably, the guide assembly includes a vertical rod fixedly mounted on the bracket, and a guide sloping plate is fixedly connected to the upper end of the vertical rod.

[0011] Preferably, the two servo motors are arranged symmetrically, and the drive ends of the two servo motors are respectively fixedly connected to the two reciprocating lead screws.

[0012] Compared with the prior art, the beneficial effects of this utility model are: After the bellows is processed, two servo motors drive the reciprocating lead screw to rotate, and two sliders move simultaneously along the groove. When the surface of the rectangular block and the surface of the limiting strip are in contact, the bellows is located directly above the guide plate. As the sliders continue to move in the same direction, they gradually squeeze the T-shaped plate into the hollow block, thereby squeezing the gas inside and delivering it to the corresponding hollow shell. The sealing block then slides inside the hollow shell. After the two clamping plates move, they will be in close contact with the lower end faces of both ends of the processed bellows, thus clamping the bellows. The process involves two electric push rods driving two fixed blocks to reset, a servo motor driving a reciprocating screw to rotate, two sliders resetting and moving, and two clamping plates disengaging from the corrugated pipe. Under gravity, the corrugated pipe falls onto the guide inclined plate, which assists in unloading the corrugated pipe. The processed corrugated pipe slides out along the inclined plate, replacing manual material handling, simplifying the operation process, and improving unloading efficiency. This spiral corrugated pipe extrusion screw machine can quickly remove the processed spiral corrugated pipe, improving processing efficiency and stably and efficiently completing the spiral extrusion screw processing process of spiral corrugated pipe.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-4 A spiral corrugated pipe extrusion screw machine includes a support 1. Two symmetrically arranged L-shaped blocks 2 are fixedly connected to the support 1. A slider 13 is slidably connected to each L-shaped block 2. A rectangular block 14 is connected to the slider 13 through a first spring 15. A clamping component is provided on one side surface of the rectangular block 14. A groove for the slider 13 to slide back and forth is opened in each L-shaped block 2. A reciprocating screw 10 is rotatably connected in the groove. The slider 13 and the reciprocating screw 10 are threadedly connected. A limit strip 11, a hollow shell 8 and a servo motor are fixedly connected to each L-shaped block 2. A sliding component is provided in each hollow shell 8. A hollow block 9 is fixedly connected in each groove. The hollow block 9 and the corresponding hollow shell 8 are connected. A T-shaped plate 12 is connected to one side inner wall of the hollow block 9 through a return spring 18. A guide component is provided on the support 1.

[0017] refer to Figure 1 Each clamping assembly includes an electric push rod 5 fixedly installed on one side surface of a rectangular block 14. The drive end of the electric push rod 5 is fixedly connected to a fixing block 3 with an isosceles trapezoidal cross-section. During production, the fixing block 3 can also be rotated and installed on the drive end of the electric push rod 5 according to actual needs. The spiral corrugated pipe to be processed is placed between two fixing blocks 3. When it is necessary to clamp the spiral corrugated pipe, each electric push rod 5 extends and pushes the fixing block 3 close to the spiral corrugated pipe. The isosceles trapezoidal structure adapts to the corrugated pipe and makes contact. With the help of the clamping assembly on the other side, the corrugated pipe is clamped and fixed. The rubber pads on the outer surface of each fixing block 3 are in close contact with the inner wall of the corrugated pipe, which can achieve a firm clamping of the corrugated pipe.

[0018] refer to Figure 3Each sliding component includes a sealing block 16 slidably installed inside the corresponding hollow shell 8. A bent rod 7 is fixedly connected to one side surface of the sealing block 16, and a clamping plate 6 is fixedly connected to one end of the bent rod 7. A second spring 17 is sleeved on each bent rod 7. One end of the second spring 17 is fixedly connected to the bent rod 7, and the other end of the second spring 17 is fixedly connected to the inner wall of the hollow shell 8. After the gas inside the hollow block 9 is transported to the corresponding hollow shell 8, the sealing block 16 will slide inside the hollow shell 8, thereby driving the bent rod 7 and the clamping plate 6 to move synchronously, and the second spring 17 will deform.

[0019] refer to Figure 2 The guide assembly includes a vertical rod fixedly installed on the bracket 1. The upper end of the vertical rod is fixedly connected to a guide plate 4. After the corrugated pipe is processed, it falls onto the guide plate 4, which can assist in the unloading of the corrugated pipe. The processed corrugated pipe slides out along the guide plate 4, replacing manual material handling, simplifying the operation process and improving unloading efficiency.

[0020] refer to Figure 2 The two servo motors are arranged symmetrically, and the drive ends of the two servo motors are fixedly connected to the two reciprocating lead screws 10 respectively. When the servo motors are working, they drive the reciprocating lead screws 10 to rotate, which in turn drives the slider 13 to move along the slide groove.

[0021] In this invention, during use, the spiral corrugated pipe to be processed is first placed between two fixed blocks 3. Two electric push rods 5 drive the two fixed blocks 3 to move closer to the spiral corrugated pipe. The rubber pads on the outer surface of each fixed block 3 are tightly attached to the inner wall of the corrugated pipe, thus clamping and fixing the corrugated pipe. After processing, the corrugated pipe can be processed. After processing, two servo motors drive the reciprocating lead screw 10 to rotate, and the two sliders 13 move simultaneously along the slide groove. When the surface of the rectangular block 14 is in contact with the surface of the limiting strip 11, the limiting strip 11 can prevent the rectangular block 14 from moving. Continuing to move in the same direction, the bellows is now directly above the guide plate 4. As the slider 13 continues to move in the same direction, the rectangular block 14 will move relative to the slider 13. Since the two ends of the first spring 15 are fixedly connected to the slider 13 and the rectangular block 14 respectively, the first spring 15 deforms. As the slider 13 continues to move, it will gradually squeeze the T-shaped plate 12, causing it to slide relative to the hollow block 9. The sealing between the T-shaped plate 12 and the inner wall of the hollow block 9 is good, and the two ends of the return spring 18 are fixedly connected to the T-shaped plate 12 and the hollow block 9 respectively. As the material moves into the hollow block 9, it compresses the gas inside, sending it into the corresponding hollow shell 8. The return spring 18 deforms, ensuring a good seal between the sealing block 16 and the inner wall of the hollow shell 8. The sealing block 16 then slides inside the hollow shell 8, causing the bending rod 7 and clamping plates 6 to move synchronously. After the two clamping plates 6 move, they come into close contact with the lower ends of the processed bellows, clamping the bellows. Then, the two electric push rods 5 drive the two fixing blocks 3 to reset, disengaging the fixing blocks 3 from the bellows. Afterward, the servo motor drives... When the reciprocating screw 10 rotates, the two sliders 13 move to reset, and the two T-shaped plates 12 reset under the elastic force of the reset spring 18. The two clamping plates 6 also reset and disengage from the bellows. Under the action of gravity, the bellows falls onto the guide plate 4 below, which can assist in the unloading of the bellows. The processed bellows slides out along the plate, replacing manual material handling, simplifying the operation process, and improving unloading efficiency. This spiral bellows extrusion screw machine can quickly remove the processed spiral bellows, improve processing efficiency, and can stably and efficiently complete the spiral bellows extrusion screw processing process.
