Description

Technical Field

[0001] This utility model relates to the field of metal forming equipment technology, specifically to an inlet protection device suitable for cold rolling of stainless steel pipes. Background Technology

[0002] In the field of stainless steel pipe cold rolling, before entering the rolling die or roller system, the pipe needs to undergo a guiding and position calibration process to ensure the correct posture and center alignment of the pipe, thereby guaranteeing the stability of the subsequent rolling process and the quality of the finished product. Therefore, the guiding device, as the front-end auxiliary structure of the cold rolling equipment, plays an important role in the entire processing flow.

[0003] In existing technologies, common pipe guiding devices mostly use fixed limiting blocks, movable guide arms, or V-groove mechanisms for initial alignment. Their structures are relatively simple, and the guiding method mainly relies on manual or passive structural adjustments. For example, some traditional guiding devices include a pair of movable baffles or rollers, with the spacing adjusted manually to accommodate pipes of different diameters, or a single-sided mechanical pushing component for positioning. While these devices can achieve basic guiding functions, they still have the following significant shortcomings in use:

[0004] The structural response is lagging and it cannot actively adjust the guide angle according to the change of pipe position: Traditional devices mostly rely on fixed structures or manual adjustment to adapt to the posture of the pipe. When the pipe enters at an incorrect angle or in an off-center position, there is a lack of effective guidance and correction mechanism, which can easily cause problems such as pipe jamming, collision, and failure to guide. Especially under high-speed continuous feeding conditions, the stability is insufficient.

[0005] Poor adaptability and inability to automatically adjust clamping distance according to different pipe diameters: Existing devices are mostly mechanical rigid structures. When facing stainless steel pipes of different diameters or wall thicknesses, the guiding accuracy is difficult to guarantee. Frequent replacement of clamps or manual fine-tuning is required, which is not only inefficient, but also poses a risk of accumulating processing errors.

[0006] Lacking intelligent sensing mechanisms, automatic identification and adjustment are impossible: Existing guiding mechanisms generally do not integrate sensors or feedback systems, making it impossible to detect and respond to changes in the end position and diameter of the tube in real time, which makes it difficult to meet the current cold rolling production line's demand for intelligent, automated, and high-efficiency operation.

[0007] Therefore, there is an urgent need to provide a stainless steel pipe guide and protection device that is compact, responsive, adaptable, and has automatic adjustment and intelligent detection capabilities, so as to achieve high-precision guidance and dynamic adjustment in the pipe guide process and improve the stability and automation level of the overall processing line. Utility Model Content

[0008] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0009] Therefore, the technical solution adopted by this utility model is as follows: a guide and protection device suitable for cold rolling of stainless steel pipes, comprising: a guide seat, a guiding component, and a detection component. The guide seat is the main load-bearing structure, the guiding component is used to position and guide the stainless steel pipe, and the detection component is used to identify the pipe's condition and drive adjustment actions. The entire device can perform position detection, guidance correction, and clamping guidance on the incoming stainless steel pipe, achieving fully automated and coordinated control throughout the process.

[0010] In a preferred embodiment, a drive cylinder is fixedly mounted on the bottom surface of the guide seat, a rotary guide sleeve is rotatably mounted inside the guide seat, and a guide rod is fixedly connected to the output end of the drive cylinder. A sliding groove is provided on the top surface of the guide seat to guide the two guide components to slide along their axial direction.

[0011] Specifically, this structure can provide linear input through a drive cylinder, and use the mechanism between the guide rod and the rotating guide sleeve to convert linear motion into rotational deflection, thereby driving the guide components to adjust in linkage and realize dynamic changes in the clamping distance.

[0012] In a preferred embodiment, the outer surface of the insertion guide rod is provided with a plurality of spiral protrusions, and the inner side of the rotary guide sleeve is provided with a spiral guide groove adapted to the protrusions, which is used to drive the rotary guide sleeve to deflect during the insertion guide rod movement.

[0013] Specifically, during the movement of the guide rod, the protrusion engages with the guide groove to form a relative rotational relationship, thereby driving the rotary guide sleeve to deflect and forming a controllable rotational output, which in turn links the clamping mechanism below to respond and adjust.

[0014] In a preferred example, two guide components are symmetrically arranged about the axis of the rotating guide sleeve. Each guide component includes a slide, a vertical plate frame, and a guide wheel rotatably mounted on the surface of the vertical plate frame. An outwardly flared guide plate is provided on one side of the vertical plate frame.

[0015] Specifically, the symmetrical arrangement ensures that the guiding components move synchronously during the adjustment process. The combination structure of the inlet plate and the guide wheel can effectively contain the pipe and guide it to center smoothly, thus improving the guiding stability.

[0016] In a preferred example, the slide rods of the two slides are arranged alternately, and the slide rod of one slide slides against the surface of the body of the other slide.

[0017] Specifically, this structure can maintain the limiting fit between components during linkage, avoid problems such as tooth skipping and instability when the rack meshes, and improve the consistency of structural response and smoothness of sliding.

[0018] In a preferred example, the straight racks of the two guide components are symmetrically arranged about the axis of the rotary guide sleeve, and are respectively engaged with the drive teeth provided on the top surface of the rotary guide sleeve.

[0019] Specifically, by converting the rotation of the rotary guide sleeve into linear sliding motion through a gear-rack structure, the two guide components can be precisely controlled to slide in opposite directions along the slide groove, achieving precise distance adjustment and stable clamping.

[0020] In a preferred example, the detection component is equipped with a material sensor or a laser rangefinder for real-time detection of the pipe end position and diameter information.

[0021] Specifically, the detection device can dynamically identify whether the pipe is misaligned or has an abnormal diameter, providing a basis for adjusting the drive cylinder and clamping distance, and realizing closed-loop control and automatic correction functions.

[0022] In a preferred example, the output of the detection component is electrically connected to the control module, and the output of the control module is electrically connected to the drive cylinder.

[0023] Specifically, when the detection module detects pipe deviation or entry, the control module can control the drive cylinder to drive the guide rod to move, and then the two guide components are linked by the rotating guide sleeve to open or clamp, ensuring stable pipe insertion and avoiding impact or interference caused by improper clamping position.

[0024] In summary, this invention achieves synchronously adjustable clamping control of the guiding component by introducing a drive-rotation-rack linkage structure, and constructs a closed-loop structure of perception-response-control in conjunction with a detection system. This solution is widely applicable to the front-end introduction scenarios of cold rolling processes for stainless steel round tubes, thin-walled tubes, etc., effectively solving the problems of lagging adjustment, unstable clamping, and poor adaptability of existing introduction structures, and has good engineering practicality and promotion prospects.

[0025] The beneficial effects achieved by this utility model are as follows:

[0026] 1. In this utility model, the linear motion of the drive cylinder is transformed into the rotational deflection of the guide sleeve through the helical engagement structure between the guide rod and the guide sleeve. Then, the meshing gear and rack mechanism drives the two symmetrically arranged guide components to achieve synchronous sliding adjustment, so that the tube can automatically correct the clamping angle according to the end position during the introduction process, ensuring that it is in an ideal centered state before entering the cold rolling equipment, which significantly improves the introduction accuracy and automation level.

[0027] 2. In this utility model, the guiding component is provided with an outwardly expanding guide plate and a guide wheel structure, and works with a sensor detection structure to identify the position and diameter of the pipe end. It can be dynamically adjusted according to different pipe diameters and entry status, effectively avoiding problems such as jamming and pipe scratches caused by guiding deviation, loose clamping or excessive interference, thus improving the stability, versatility and production line operating efficiency of the equipment.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0038] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0039] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an inlet protection device suitable for cold rolling of stainless steel pipes.

[0040] Combination Figures 1-5 As shown, the present invention provides an inlet protection device suitable for cold rolling of stainless steel pipes, including a guide seat 100, a guide component 200 and a detection component 300.

[0041] A drive cylinder 110 is fixedly mounted on the bottom surface of the guide seat 100 to provide the power source for the insertion action. A rotating guide sleeve 130 is provided in the center of the guide seat 100, and the rotating guide sleeve 130 can rotate relative to the guide seat 100. An insertion guide rod 120 is fixedly connected to the output end of the drive cylinder 110, and the insertion guide rod 120 can reciprocate up and down along the axial direction under the action of the drive cylinder 110.

[0042] The top surface of the guide seat 100 is provided with a sliding groove 101 for guiding the two guide components 200 to slide relative to each other. The two guide components 200 are symmetrically arranged on both sides of the guide seat 100, and the sliding direction is consistent with the meshing direction of the rotary guide sleeve 130.

[0043] like Figure 3 and Figure 4 As shown, the guiding assembly 200 includes a slide block 210, a vertical plate frame 220, and guide wheels 230 rotatably mounted on the outer surface of the vertical plate frame 220. The guide wheels 230 are used to contact the outer surface of the stainless steel pipe to achieve flexible support and guidance. The slide block 210 is disposed in the slide groove 101 and can be adjusted relative to the guide sleeve 130 by sliding.

[0044] The slide block 210 has a slide rod 211 on its surface, and a rack 212 is fixedly connected to the bottom surface of the slide rod 211 for meshing with the drive teeth 131 provided on the top of the rotary guide sleeve 130. The drive teeth 131 drive the rack 212 to slide through the deflection motion of the rotary guide sleeve 130, thereby pushing the slide block 210 to move and realize the relative approach or distance between the two guide components 200.

[0045] like Figure 2 and Figure 5 As shown, in a preferred embodiment, the outer surface of the insertion guide rod 120 is provided with several helical protrusions, and the inner side of the rotary guide sleeve 130 is provided with a helical guide groove adapted to the protrusions, which is used to drive the rotary guide sleeve to deflect during the movement of the insertion guide rod 120. When the insertion guide rod 120 moves axially under the drive cylinder 110, its helical protrusions cooperate with the helical guide groove of the rotary guide sleeve 130, thereby driving the rotary guide sleeve 130 to rotate and deflect. The rotation of the rotary guide sleeve 130 drives the top drive tooth 131 to rotate synchronously, realizing the synchronous adjustment of the position of the two guide components 200.

[0046] like Figure 1 and Figure 3 As shown, there are two guide components 200, which are arranged symmetrically about the axis of the rotary guide sleeve 130 to facilitate equidistant adjustment. Each of the two guide components 200 has an outwardly expanding guide plate 221 on one side of its upright frame 220. The guide plate 221 adopts an arc-shaped structure design, which can flexibly guide the stainless steel tube when it is close, avoiding jamming or scratching.

[0047] like Figure 3 As shown, the slide rods 211 of the two slide blocks 210 are arranged in an alternating manner. The slide rod 211 of one slide block 210 forms a sliding contact relationship with the body surface of the other slide block 210, ensuring that the guiding process is synchronous and stable and improving the overall clamping rigidity.

[0048] The straight racks 212 on the surfaces of the two guide components 200 respectively mesh with the drive teeth 131 on the top of the rotary guide sleeve 130, and are symmetrically arranged about their central axis, so that when the rotary guide sleeve 130 deflects, it can simultaneously drive the two racks to make linear movements synchronously, ensuring that the overall movement of the guide components 200 is consistent.

[0049] like Figure 1 As shown, the detection component 300 is located at the front end of the guide seat 100, near the stainless steel pipe entry area. The surface of the detection component 300 is equipped with a material sensor or a laser rangefinder sensor to detect the end position and diameter of the stainless steel pipe. This detection data is used to determine whether the stainless steel pipe is centered and provides a reference for subsequent guiding actions.

[0050] like Figure 1 and Figure 2 As shown, the output of the detection component 300 is electrically connected to a control module, and the output of the control module is electrically connected to the input of the drive cylinder 110. Specifically, when the detection component 300 detects that the pipe end is offset or the guide posture is incorrect, the control module controls the drive cylinder 110 to move, driving the guide rod 120 to move axially, and then adjusting the position of the two guide components 200 by rotating the guide sleeve 130, so that they open outward, increasing the distance between the upright frame 220 and preventing the pipe from getting stuck.

[0051] Once the pipe enters the guide channel, the detection component 300 further determines the pipe diameter and feeds it back to the control module. The control module then controls the drive cylinder 110 to continue adjusting, causing the two upright frames 220 to slowly move closer to each other. Finally, the guide plate 221 and guide wheel 230 complete the guidance and clamping of the pipe, improving the accuracy of the guide and the versatility of the device.

[0052] This invention achieves intelligent guidance, automatic distance adjustment, and centering clamping control of stainless steel pipes before they enter the cold rolling process through the coordinated operation of the drive cylinder, insertion guide rod, rotating guide sleeve, slide block, and linkage rack structure, combined with the front-end intelligent detection mechanism. It has the advantages of compact structure, precise linkage, and sensitive response, and is suitable for continuous and efficient cold rolling production lines.

[0053] Working principle and usage process of this utility model:

[0054] This utility model provides an inlet protection device suitable for cold rolling of stainless steel pipes. It mainly achieves automatic adjustment and clamping stability of the pipe inlet direction and position through the coordinated cooperation of the guide component and the rotating guide sleeve.

[0055] The specific work process is as follows:

[0056] When the stainless steel pipe approaches the front end of the inlet device, the detection component 300 acquires the position and diameter information of the pipe end in real time through the sensor, and transmits the data to the control module for calculation and analysis.

[0057] If pipe misalignment or incorrect guide position is detected, the control module controls the drive cylinder 110 to move, causing the insertion guide rod 120 to move axially. The spiral protrusions on the surface of the insertion guide rod 120 engage with the spiral grooves on the inner wall of the rotary guide sleeve 130, causing the rotary guide sleeve 130 to deflect and rotate, thereby driving the drive tooth 131 at its top to rotate.

[0058] The drive gear 131 meshes with the rack 212 below the two symmetrically arranged slide blocks 210. Through the gear-rack transmission, the two guide components 200 are driven to slide relative to each other along the slide groove 101, thereby increasing or decreasing the distance between the upright frame 220 and the guide plate 221.

[0059] Once the end of the pipe enters the guide zone and its position is corrected, the control system further adjusts the two guide components 200 to move closer together based on the detected pipe diameter. The guide plate 221 clamps and guides the pipe on both sides, ensuring that it smoothly enters the next rolling process.

[0060] This invention achieves intelligent positioning and guidance control of incoming pipes through a composite structure of mechanical transmission, intelligent detection, and dynamic adjustment, significantly improving the automation level and operational stability of the cold rolling line.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
