Description

Technical Field

[0001] This utility model relates to the field of steel lining processing technology, and in particular to a steel lining roll forming machine. Background Technology

[0002] Steel lining is a composite material, usually made of steel and other materials. It is used to improve the performance of equipment by attaching or coating steel or other materials inside pipes, containers, etc. The processing of steel lining is to gradually press the metal plate through a series of orderly arranged rollers on a roll forming machine. The metal plate passes through each roller in turn, and each roller applies a certain pressure to the plate, causing it to gradually undergo plastic deformation and finally form the required cross-sectional shape.

[0003] The rolls in a steel liner roll forming machine are the main components in the steel liner processing and forming. However, impurities (such as metal shavings) adhering to the rolls can leave indentations, scratches, or bumps on the steel liner surface, damaging the surface flatness. Rolls that have been running for a long time will deform, resulting in dimensional accuracy deviations. Roll deformation (such as bending or local dents) will lead to uneven contact pressure between the rolls and the sheet metal, causing deviations in the cross-sectional dimensions of the steel liner, such as inconsistent thickness or edge warping, reducing the yield of steel liners and wasting raw materials.

[0004] Therefore, it is necessary to provide a new steel-lined roll forming machine to solve the above-mentioned technical problems. Utility Model Content

Inside the housing, from top to bottom, are a trigger cavity and a sliding cavity. A trigger plate and a detection plate are slidably connected in the trigger cavity and the sliding cavity, respectively.

A vertical sliding rod is fixedly installed between the trigger plate and the detection plate, passing through the cavity wall between the trigger cavity and the sliding cavity and slidably connected thereto. Stationary contacts are fixedly installed on the upper and lower inner walls of the trigger cavity, and moving contacts corresponding to and adapted to the stationary contacts are fixedly installed on the top and bottom surfaces of the trigger plate.

[0024] 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 the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 6This utility model provides a steel liner roll forming machine, which includes two mounting frames 5 symmetrically distributed on the frame of the roll forming machine. Each mounting frame 5 is equipped with a mounting base 1, and a connecting rod 2 is fixedly installed between the two mounting bases 1. A row of detection structures 3 for detecting the state of the roll is installed on the connecting rod 2 along its length. Each detection structure 3 includes a housing 31, and the housing 31 has a through hole 311 for the connecting rod 2 to pass through. The housing 31 has a trigger cavity 312 and a sliding cavity 313 from top to bottom. A trigger plate is slidably connected in the trigger cavity 312 and the sliding cavity 313 respectively. Trigger plate 32 and detection plate 33, with detection plate 33 penetrating through slide cavity 313 and extending to the outside of housing 31 to fit against the outer circumferential surface of roll forming machine. A vertical slide rod 34 is fixedly installed between trigger plate 32 and detection plate 33, and slide rod 34 penetrates the cavity wall between trigger cavity 312 and slide cavity 313 and slides therewith. Stationary contacts 36 are fixedly installed on the upper and lower inner walls of trigger cavity 312, and moving contacts 37 corresponding to and adapted to stationary contacts 36 are fixedly installed on the top and bottom surfaces of trigger plate 32. A spring 35 in a compressed state is sleeved on slide rod 34, and the upper and lower ends of spring 35 abut against the inner top wall of slide cavity 313 and detection plate 33, respectively.

[0027] It should be noted that: the device in this utility model is fixed to the frame of the roll forming machine by the mounting bracket 5. The connecting rod 2 between the two mounting seats 1 is used for the installation of a row of detection structures 3. The detection plate 33 on the detection structure 3 is in close contact with the rolls on the roll forming machine. The trigger plate 32 is connected and fixed to the detection plate 33 by the sliding rod 34. The trigger plate 32 and the detection plate 33 can slide in the trigger cavity 312 and the sliding cavity 313 respectively. In the initial state, the spring 35 of the detection structure 3 is in a compressed state, and its elastic force presses against the detection... The measuring plate 33 is kept in constant contact with the outer circumference of the roll. At this time, the trigger plate 32 remains in the middle of the trigger cavity 312, and the moving contacts 37 on both the upper and lower sides are not in contact with the stationary contact 36. The circuit is open, and there is no abnormal signal. When a protrusion, deformation, or steel lining residue adheres to the roll surface, the protrusion will press against the measuring plate 33, causing the measuring plate 33 to slide upwards along the sliding cavity 313. This, in turn, drives the trigger plate 32 to move upwards synchronously via the sliding rod 34. Finally, the moving contact 37 on the top surface of the trigger plate 32 contacts the inner wall of the trigger cavity 312. When the stationary contact 36 contacts, the circuit is connected and an abnormal signal of "roll surface protrusion" is sent. When the roll surface is dented, worn, or partially missing, the detection plate 33 loses the support of the roll and slides downward under the restoring force of the spring 35. The detection plate 33 drives the slide rod 34 and the trigger plate 32 to move downward synchronously. The moving contact 37 on the bottom surface of the trigger plate 32 contacts the stationary contact 36 on the lower inner wall of the trigger cavity 312, connecting the circuit and sending an abnormal signal of "roll surface dent". This utility model can detect the roll surface protrusion in real time through the detection structure 3. Precise monitoring of roll anomalies can identify various abnormalities such as bulges, dents, and wear in real time, preventing defects such as steel liner forming size deviations and surface scratches caused by roll problems. It can also detect problems such as roll adhesion residue and local missing parts in advance, preventing the roll from continuing to operate under abnormal conditions, reducing excessive friction and damage between the roll and other parts of the equipment. Abnormal signals are triggered immediately, enabling rapid shutdown and adjustment, preventing the generation of batches of unqualified products, reducing raw material waste, and setting up multiple detection structures 3 to perform comprehensive inspection of the rolls.

[0028] In addition, the stationary contact 36 and the moving contact 37 are connected to the external circuit system and are used in conjunction with the corresponding alarm to alarm abnormal signals. This is a technical method commonly used by those in this field, so it will not be elaborated on further. At the same time, a unique ID identification module can be installed on the outer shell 31 of each detection structure 3 to link with the external control unit. When a certain detection structure 3 triggers an abnormal signal, the control unit can display the ID of the detection structure 3 and the corresponding roll position in real time, without the need for manual inspection one by one.

[0029] The end of the connecting rod 2 abuts against the mounting base 1. The end of the mounting base 1 away from the connecting rod 2 has a groove 11. A screw 21 that penetrates the mounting base 1 is installed in the groove 11. The screw 21 is threadedly connected to the end of the connecting rod 2 and abuts against the inner wall of the groove 11. The screw 21 is used for the detachable connection between the connecting rod 2 and the mounting base 1. The groove 11 provides space for the screw 21 and also abuts against the screw 21 through its inner wall, thus limiting the radial movement of the screw 21.

[0030] It is worth noting that: the top of the mounting frame 5 has a mounting hole 51 for connecting to the roll forming machine, and the bottom of the mounting frame 5 has an adjusting groove 52, in which a vertical threaded rod 53 is fixedly installed. A sliding sleeve 12 is fitted onto the threaded rod 53 and is slidably connected to it. The sliding sleeve 12 is fixedly installed on the mounting base 1. Two adjusting bolts 54 are threaded onto the threaded rod 53 and are threadedly connected to it. The two adjusting bolts 54 abut against the upper and lower ends of the sliding sleeve 12, respectively. The mounting hole 51 on the mounting frame 5 is used to bolt the mounting frame 5 to the frame of the roll forming machine. Through the cooperation of the threaded rod 53, the sliding sleeve 12, and the adjusting bolts 54, the roll forming machine can be connected to the machine frame. Tightening the upper and lower adjusting bolts 54 causes the sliding sleeve 12 (and mounting base 1, connecting rod 2, and detection structure 3) to slide up and down along the threaded rod 53, precisely adjusting the contact height between the detection plate 33 and the roll. This adapts to the diameter differences of rolls of different specifications or compensates for the wear of rolls after long-term use, ensuring that the detection plate 33 is always in close contact with the roll surface, guaranteeing detection accuracy. The adjustment operation is simple and quick, facilitating rapid adaptation to production needs (such as replacing rolls or adjusting steel liner forming parameters), reducing downtime for adjustment, and improving maintenance efficiency. At the same time, the sliding sleeve 12 can be fixed to the mounting base 1 with bolts, allowing for disassembly and facilitating assembly and maintenance.

[0031] The specific shape of the mounting frame 5 can be processed and adjusted according to the position and tilt angle of the roll in the roll forming machine, so as to adapt to the roll in different states to install and fix the detection mechanism 3.

[0032] Furthermore, a limiting groove 55 is provided at the lower end of the mounting bracket 5, and a limiting rod 13 fixedly connected to the side wall of the mounting base 1 is slidably connected in the limiting groove 55. The limiting rod 13 can slide along the limiting groove 55. The limiting rod 13 is fixed to the side wall of the mounting base 1 and embedded in the limiting groove 55, which can forcibly constrain the movement direction of the mounting base 1, so that it can only slide up and down along the threaded rod 53 (vertical direction), avoiding radial displacement of the mounting base 1 in the left and right or front and back due to machine vibration or adjustment operation, and improving the stability of the device.

[0033] To reduce assembly difficulty, both ends of the connecting rod 2 are chamfered to facilitate the end of the connecting rod 2 passing through the through hole 311 on the outer casing 31.

[0034] A top block 38 is fixedly installed on the outer wall of the outer shell 31 for clearance fit between two adjacent outer shells 31; the top block 38 can force adjacent outer shells 31 to maintain a fixed gap, avoiding the situation of "too sparse to miss detection" or "too dense to waste" due to uneven spacing during installation. A row of detection structures 3 is evenly distributed through the top block 38, which can completely cover the entire length of the roll. Each detection plate corresponds to a fixed area, eliminating the detection blind spot on the surface of the roll.

[0035] It is also worth noting that the lower end of the detection plate 33 has a concave arc-shaped structure, and the curvature of this concave arc is consistent with the curvature of the outer circumference of the roll of the roll forming machine. The lower corner of the detection plate 33 is chamfered. The concave arc curvature is completely consistent with the outer circumference of the roll, which allows the detection plate 33 to form a surface contact with the roll surface, rather than a local point contact, greatly increasing the contact area. The arc-shaped contact surface makes the force between the detection plate 33 and the roll more uniform, avoiding excessive local force that could cause the detection plate 33 to jam. This ensures that it can slide smoothly up and down when abnormally triggered. The chamfered lower corner of the detection plate 33 eliminates sharp edges, which can prevent scratching the outer circumference of the roll when it rotates with the roll, and prevent damage to the roll surface from affecting the forming quality of the steel lining. At the same time, the chamfered lower end allows impurities and debris adhering to the roll to slide smoothly over the detection plate 33, preventing impurities and debris from laterally squeezing the detection plate 33 and causing damage.

[0036] In the embodiments of this utility model, please refer to Figure 1 and Figure 6 The connecting rod 2 is equipped with two limiting structures 4 for limiting the detection structure 3. The two limiting structures 4 are located at both ends of a row of detection structures 3 and are set against them. Each limiting structure 4 includes a limiting plate 41, and the limiting plate 41 is provided with a sliding hole 42 for the connecting rod 2 to pass through. The limiting plate 41 is threaded with a locking bolt 43 whose end abuts against the connecting rod 2.

[0037] It should be noted that: the limiting plate 41 is fitted onto the connecting rod 2 through the sliding hole 42, moves to both ends of the row of detection structures 3 and abuts against the edge detection structures 3, determines the axial range of the row of detection structures 3, tightens the locking bolt 43 on the limiting plate 41 so that the bolt end abuts tightly against the connecting rod 2, fixes the position of the limiting plate 41 by friction, and thus restricts the detection structure 3 from sliding along the axial direction of the connecting rod 2. If it is necessary to change the detection range or add or remove detection structures 3, simply loosen the locking bolt 43, slide the limiting plate 41 to the new position and then tighten it again, without affecting the up and down sliding function of the detection structure 3.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
