Description

Technical Field

[0001] This utility model relates to the field of calibration device technology, specifically to a calibration device for injection-molded steel pipe production. Background Technology

[0002] Injection-molded steel pipe is a new type of composite material pipe that combines steel pipe and plastic through injection molding. It usually uses steel pipe such as carbon steel or stainless steel as the base material. Through injection molding, special anti-corrosion plastic material is melted and injected into the inner cavity of the steel pipe, forming a tightly adhered plastic anti-corrosion layer on the inner wall of the steel pipe. Then, after curing treatment, the plastic layer is stable and firm.

[0003] The performance of injection-molded steel pipes depends on the stability of the steel pipe substrate. If the steel pipe itself has problems such as bending, excessive ovality, or uneven end face, it will directly lead to uneven plastic layer thickness and poor adhesion during subsequent injection molding, and even bubbles and cracks. Therefore, the steel pipe substrate correction must be completed before injection molding. During correction, the bending position and degree of the steel pipe are first detected by a laser straightening instrument to locate the bending protrusion. Then, a hydraulic jack or mechanical roller is used to apply reverse pressure to the bending protrusion to cause plastic deformation of the steel pipe and gradually restore it to a straight line. However, the current correction device requires repeated application of reverse pressure when correcting large positioning bending protrusions on the steel pipe. It is not convenient to adjust the correction range according to the range of the positioning bending protrusion, resulting in low correction efficiency. Utility Model Content

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] Please see Figures 1 to 4A straightening device for injection-molded steel pipe production includes a laser straightening instrument 1 and a straightening pressure roller 2, as well as a straightening platform 3, a placement platform 4, an anti-deviation component, a lifting cylinder 5, an adjusting pressure roller 6, and an adjusting component. The placement platform 4 is fixedly connected to the top of the straightening platform 3, and a placement groove for placing the injection-molded steel pipe is opened on the placement platform 4. The anti-deviation component is installed on one side of the placement platform 4. The lifting cylinder 5 is raised and lowered on the upper side of the placement platform 4 through the lifting component, and both the laser straightening instrument 1 and the straightening pressure roller 2 are installed on the lifting cylinder 5. The laser straightening instrument 1 can detect the bending position and curvature of the injection-molded steel pipe. Two adjusting pressure rollers 6 are provided, and the two adjusting pressure rollers 6 are moved towards each other on both sides of the straightening pressure roller 2. The adjusting component is installed between the two adjusting pressure rollers 6.

[0047] refer to Figure 1 as well as Figure 4 The anti-deviation assembly includes a support frame 7, a double-headed electric cylinder 8, an anti-deviation strip 9, an anti-deviation plate 10, and an anti-deviation pad 11. The support frame 7 is fixedly connected to the top of the calibration table 3. The double-headed electric cylinder 8 is installed on one side of the support frame 7. There are two anti-deviation strips 9. The anti-deviation strips 9 are fixedly connected to the output end of the double-headed electric cylinder 8 and are slidably connected to the support frame 7. The anti-deviation plate 10 is fixedly connected to each anti-deviation strip 9. The anti-deviation pad 11 is fixedly connected to each anti-deviation plate 10. An anti-deviation block 29 is fixedly connected to one side of the anti-deviation plate 10. The support frame 7 is provided with an anti-deviation groove for the anti-deviation block 29 to slide, which increases the stability of the anti-deviation strip 9 sliding on the support frame 7, so that the anti-deviation strip 9 can drive the anti-deviation plate 10 and the anti-deviation pad 11 to move stably.

[0048] When the double-headed electric cylinder 8 is started, the two anti-deviation strips 9 drive the two anti-deviation plates 10 to move towards each other. This allows the two anti-deviation plates 10 and the two anti-deviation pads 11 to clamp and fix injection-molded steel pipes of different specifications, preventing the injection-molded steel pipes from shifting and thus improving the stability of the correction of the injection-molded steel pipes.

[0049] refer to Figure 1 The lifting assembly includes an electric push rod 12, a lifting frame 13, a lifting push rod 14, a stabilizing plate 15, and a stabilizing rod 16. The electric push rod 12 is mounted on the support frame 7. The lifting frame 13 is fixedly connected between the output end of the electric push rod 12 and the lifting cylinder 5. Multiple lifting push rods 14 are arranged in an array on the lifting cylinder 5, which can stably apply pressure to correct the correction roller 2 and the two adjusting rollers 6. Two stabilizing plates 15 are arranged, and the two stabilizing plates 15 are symmetrically connected on both sides of the support frame 7. Two stabilizing rods 16 are arranged, and the two stabilizing rods 16 are symmetrically connected on the lifting frame 13. The stabilizing plate 15 is provided with a stabilizing opening that matches the stabilizing rod 16.

[0050] When the electric push rod 12 is activated, the lifting frame 13 moves the lifting cylinder 5. This allows the lifting cylinder 5 to move the motor 17, threaded rod 18, connecting rod 19, correction pressure block 20, adjusting pressure block 21, correction pressure roller 2, and adjusting pressure roller 6, thereby adjusting the correction height. Simultaneously, during the lifting process of the lifting cylinder 5, the two stabilizer rods 16 move within the two stabilizer openings on the two stabilizer plates 15, increasing the stability of the movement of the lifting cylinder 5 and thus improving the stability of the pressure applied during the descent of the injection-molded steel pipe.

[0051] refer to Figure 1 as well as Figure 2 The adjustment assembly includes a motor 17, threaded rods 18, connecting rods 19, a correcting pressure block 20, an adjusting pressure block 21, and a limiting block 22. The motor 17 is mounted on one side of the lifting cylinder 5. Two threaded rods 18 are symmetrically arranged within the lifting cylinder 5. The output end of the motor 17 is fixedly connected to the adjacent threaded rod 18, and both threaded rods 18 have threads in opposite directions. The connecting rod 19 is fixedly connected to the two threaded rods 18. The correcting pressure block 20 is fixedly connected to the lifting cylinder 5, and the correcting pressure block 20 has a through-hole matching the connecting rod 19. When the two threaded rods 18 rotate, the connecting rod 19 also rotates within the through-hole. The correcting pressure roller 2 is detachably connected to the lifting cylinder 5. Two adjusting pressure blocks 21 are connected to the bottom end of the correction pressure block 20. The two adjusting pressure blocks 21 are threadedly connected to the two threaded rods 18 respectively. The initial positions of the two adjusting pressure blocks 21 on the two threaded rods 18 are the same. At the same time, the motor 17 is set to drive the two threaded rods 18 to perform forward and reverse rotation. The two adjusting pressure rollers 6 are detachably connected to the bottom end of the two adjusting pressure blocks 21 respectively. Multiple limiting blocks 22 are set. The multiple limiting blocks 22 are connected to the two adjusting pressure blocks 21 respectively. The lifting cylinder 5 is provided with a limiting groove for the sliding of the limiting blocks 22, which can limit the sliding of the adjusting pressure blocks 21 in the lifting cylinder 5 and increase the stability of the adjusting pressure blocks 21 driving the adjusting pressure rollers 6 to move.

[0052] Start the motor 17, which drives the two threaded rods 18 to rotate simultaneously through the connecting rod 19. This allows the two adjusting pressure blocks 21 to move towards each other inside the lifting cylinder 5, thereby adjusting the position of the two adjusting pressure rollers 6 according to the range of the positioning bending protrusion of the injection-molded steel pipe.

[0053] refer to Figure 2 Two adjusting pressure plates 26 are fixedly connected to splicing plates 23 on the side near the correcting pressure plate 25. Two splicing slots matching the splicing plates 23 are symmetrically opened on the correcting pressure plate 25. Multiple locking rods 24 are fixedly connected on the adjusting pressure roller 6. Multiple locking slots matching the locking rods 24 are symmetrically opened on the correcting pressure roller 2.

[0054] When the two adjusting pressure plates 26 move toward each other and approach the correcting pressure plate 25, the two splicing plates 23 will enter the two splicing slots, and at the same time, multiple clamping rods 24 will be inserted into multiple clamping slots respectively, which increases the stability of the splicing of the correcting pressure plate 25 and the two adjusting pressure plates 26, so that the correcting pressure roller 2 and the two adjusting pressure rollers 6 can apply stable pressure to correct the protrusion of the injection-molded steel pipe.

[0055] refer to Figure 2 as well as Figure 3 The bottom ends of the correction pressure block 20 and the adjustment pressure block 21 are respectively fixedly connected to the correction pressure plate 25 and the adjustment pressure plate 26. Multiple mounting plates 27 are respectively fixedly connected to the correction pressure roller 2 and the adjustment pressure roller 6. Multiple mounting screws 28 are threadedly connected between the multiple mounting plates 27 and the correction pressure plate 25 and the adjustment pressure plate 26.

[0056] Multiple mounting screws 28 are tightened between the correction plate 25, the two adjusting plates 26 and the multiple mounting plates 27 to facilitate the quick installation and removal of the multiple mounting plates 27 on the correction plate 25 and the adjusting plate 26, thereby enabling the quick installation and removal of the correction roller 2 and the adjusting roller 6 on the correction block 20 and the adjusting block 21.

[0057] In summary, the alignment device for injection-molded steel pipe production first places the injection-molded steel pipe on the placement platform 4, and uses a laser straightening instrument 1 to detect the bending position and degree of curvature of the injection-molded steel pipe, locating the "high point" (the bending protrusion). Simultaneously, the double-headed electric cylinder 8 is activated, causing the two anti-deviation strips 9 to move the two anti-deviation plates 10 and two anti-deviation pads 11 towards each other, clamping and fixing the injection-molded steel pipe. When the bending protrusion range of the injection-molded steel pipe is large, the motor 17 is activated, causing the two adjusting pressure blocks 21 to rotate through the two threaded rods 18. The rollers move towards each other, causing the two adjusting pressure plates 26 to gradually approach the correcting pressure plate 25, and the two splicing plates 23 and multiple clamping rods 24 to be inserted into the two splicing slots and multiple clamping slots respectively. After the correcting pressure roller 2 and the two adjusting pressure rollers 6 are spliced, the electric push rod 12 is started, causing the lifting frame 13 to drive the lifting cylinder 5, the correcting pressure roller 2 and the two adjusting pressure rollers 6 to move. This allows the correcting pressure roller 2 and the two adjusting pressure rollers 6 to apply reverse pressure to correct the bent protrusions of the injection-molded steel pipe, thereby improving the correction efficiency of the injection-molded steel pipe.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
