Description

Technical Field

[0001] This invention belongs to the field of metal processing technology, and in particular relates to a flattening and forming machine for electric furnace bars. Background Technology

[0002] In the electric furnace bar flattening process, the uniformity of thickness is a core factor determining product quality. Currently, Traditional production relies mainly on manual sampling or stop-work inspection. This method is not only inefficient and prone to missed inspections due to visual fatigue, but also cannot capture instantaneous thickness deviations caused by roll jumps or tension fluctuations in real time. Although electronic inspection equipment such as laser thickness gauges exist on the market, they are expensive, have poor stability in the high-temperature rolling environment with a lot of metal dust, and are difficult to maintain, thus affecting the production efficiency of furnace bars. Summary of the Invention

[0003] To address the problems existing in the prior art, this invention provides a special flattening and forming machine for electric furnace bars, which solves the problem that existing equipment cannot detect the different thicknesses of the flattened furnace bars in a timely manner during production.

[0004] This invention is implemented as follows: a flattening and forming machine for electric furnace bars, comprising a flattening machine, a fixing frame and two support frames used on the flattening machine, and further comprising: A detection assembly for detecting the thickness of flattened furnace bars, mounted on a support frame, the detection assembly including a detection wheel movably mounted on one of the support frames; Another support frame is provided with a marking assembly for marking the thickness of the furnace bars. The marking assembly includes a marking cylinder fixedly mounted on the support frame and a connecting pipe slidably mounted inside the marking cylinder. The marking cylinder and the connecting pipe are movably connected. When the detection wheel moves, the marking cylinder and the connecting pipe communicate with each other and spray liquid to mark the furnace bars.

[0005] As a preferred embodiment of the present invention, a lifting component for moving the connecting pipe is provided between the connecting pipe and the detection wheel.

[0006] As a preferred embodiment of the present invention, the lifting assembly includes a lifting rod slidably disposed on one of the support frames, a pull rod hinged to one end of the lifting rod, the other end of the pull rod hinged to a connecting pipe, a bracket disposed on one of the support frames, and the middle part of the pull rod hinged to the bracket.

[0007] As a preferred embodiment of the present invention, a spring is fitted onto the lifting rod.

[0008] In a preferred embodiment of the present invention, a fixing ring is provided at both ends of the spring, and the lifting rod passes through the two fixing rings. One fixing ring is fixedly mounted on the support frame, and the other fixing ring is fixedly mounted on the lifting rod. An alarm component for detecting thickness alarm is provided between the two fixing rings.

[0009] As a preferred embodiment of the present invention, the alarm component includes electrode posts respectively disposed on two fixed rings, the electrode posts being divided into positive electrode posts and negative electrode posts, and a buzzer alarm electrically connected to the electrode posts is disposed on the support frame.

[0010] As a preferred embodiment of the present invention, the marking assembly further includes a first through hole formed on the connecting pipe and a pair of second through holes formed on the marking cylinder. The marking cylinder has a hollow interlayer inside, and the second through holes are interconnected with the interlayer. The second through holes are movably connected with the first through holes, and a storage box that is interconnected with the connecting pipe is provided on one of the support frames.

[0011] As a preferred embodiment of the present invention, a nozzle is provided at the bottom of the marking cylinder.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention directly senses changes in the thickness of the furnace bars through a detection wheel and uses a lever mechanism to convert the vertical displacement of the detection wheel into control of the connection and disconnection between the connecting pipe and the marking cylinder. This achieves the purpose of automatically spraying liquid for marking when the thickness is abnormal and stopping marking when the thickness is normal, realizing fully automatic online thickness detection and abnormal point marking for flattened furnace bars without the need for manual visual inspection or machine stop measurement. At the same time, the two second through holes at the top and bottom cooperate with the first through hole on the connecting pipe, so that marking liquid is triggered to spray regardless of whether the furnace bar is too thick (connecting pipe moves down) or too thin (connecting pipe moves up), achieving the purpose of effectively marking both positive and negative thickness deviations, realizing full coverage of detection marking, and avoiding missed detection of unidirectional deviations. In addition, the movement of the lifting rod is linked with the electrode posts on the fixing rings on both sides of the spring, automatically triggering a buzzer alarm when the thickness deviation exceeds the allowable range, achieving the purpose of timely warning to the operator while marking abnormal positions, realizing a dual reminder mechanism, facilitating timely adjustment of flattening machine parameters, and reducing waste generation.

Detailed Implementation

[0015] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0016] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0017] like Figures 1 to 6 As shown in the figure, an embodiment of the present invention provides a flattening and forming machine for electric furnace bars, including a flattening machine 1, a fixing frame 2 and two support frames 3 applied on the flattening machine 1, and further including: A detection component 4 for detecting the flattening thickness of furnace bars is installed on the support frame 3. The detection component 4 includes a detection wheel 41 that is movably installed on one of the support frames 3. Another support frame 3 is equipped with a marking component 6 for marking the thickness of the grate bars. The marking component 6 includes a marking cylinder 61 fixedly mounted on the support frame 3 and a connecting pipe 62 slidably mounted inside the marking cylinder 61. The marking cylinder 61 and the connecting pipe 62 are movably connected. When the detection wheel 41 moves, the marking cylinder 61 and the connecting pipe 62 communicate with each other and spray liquid to mark the grate bars. When the flattening machine 1 flattens the grate bars, the grate bars pass through the detection wheel 41. At this time, the detection wheel 41 contacts the grate bars. When the thickness of the grate bars changes, the detection wheel 41 moves up and down. When the detection wheel 41 moves up and down, it pushes the connecting pipe 62 to move up and down. When the connecting pipe 62 moves up and down, it communicates with the marking cylinder 61. When the marking cylinder 61 and the connecting pipe 62 are connected, liquid will be sprayed out from the marking cylinder 61 and sprinkled on the grate bars to mark the positions where the grate bars have different thicknesses.

[0018] As a preferred embodiment of the present invention, a lifting component 5 for moving the connecting pipe 62 is provided between the connecting pipe 62 and the detection wheel 41. When the detection wheel 41 moves up and down, the connecting pipe 62 can be moved up and down by the lifting component 5, so that the liquid can be fully sprayed out.

[0019] As a preferred embodiment of the present invention, the lifting assembly 5 includes a lifting rod 51 slidably disposed on one of the support frames 3. A pull rod 53 is hinged to one end of the lifting rod 51, and the other end of the pull rod 53 is hinged to the connecting pipe 62. A bracket is provided on one of the support frames 3, and the middle part of the pull rod 53 is hinged to the bracket. When the thickness of the furnace bar increases or decreases, the lifting rod 51 rises or falls. When the lifting rod 51 rises or falls, it will pull the end of the pull rod 53 to move, thereby pulling the connecting pipe 62 to move. Through the movement of the connecting pipe 62, the connecting pipe 62 can be connected to the marking cylinder 61, thereby spraying out liquid to mark the furnace bar.

[0020] As a preferred embodiment of the present invention, a spring 52 is fitted on the lifting rod 51. When the lifting rod 51 slides, the spring 52 deforms. When the thickness of the furnace bar is normal, the spring 52 can push the lifting rod 51 to reset, thereby disconnecting the connecting pipe and the marking cylinder 61 again.

[0021] As a preferred embodiment of the present invention, a fixing ring is provided at both ends of the spring 52, and the lifting rod 51 passes through the two fixing rings. One fixing ring is fixedly mounted on the support frame 3, and the other fixing ring is fixedly mounted on the lifting rod 51. An alarm component 7 for detecting thickness alarm is provided between the two fixing rings, which effectively detects the pressing of the furnace bars to remind the staff.

[0022] As a preferred embodiment of the present invention, the alarm component 7 includes electrode posts 71 respectively disposed on two fixed rings. The electrode posts 71 are divided into positive posts and negative posts. A buzzer alarm 72 electrically connected to the electrode posts 71 is disposed on the support frame 3. When the spring 52 deforms, it means that the thickness of the furnace bar changes. At this time, the electrode posts 71 can be electrically connected, so that the buzzer alarm 72 will sound an alarm to remind the staff. The electrode posts 71 are figure-eight shaped (not shown in the figure), which can ensure that the buzzer alarm 72 can be controlled to sound an alarm regardless of whether the lifting rod 51 moves up or down.

[0023] As a preferred embodiment of the present invention, the marking component 6 further includes a first through hole 63 formed on the connecting pipe 62 and a pair of second through holes 64 formed on the marking cylinder 61. The marking cylinder 61 has a hollow interlayer inside, and the second through holes 64 are interconnected with the interlayer. The second through holes 64 are movably connected with the first through holes 63. A storage box 66 that is interconnected with the connecting pipe 62 is provided on one of the support frames 3. The initial position of the first through hole 63 is located between the two second through holes 64. When the connecting pipe 62 moves up or down, the first through hole 63 and the second through holes 64 are connected. At this time, the liquid in the storage box is discharged through the first through hole 63 and the second through hole 64, so that it is sprayed on the surface of the furnace grate.

[0024] As a preferred embodiment of the present invention, a nozzle 65 is provided at the bottom of the marking cylinder 61, which can fully spray out the marking liquid to achieve the marking purpose, so as to facilitate subsequent operations by the operator.

[0025] Working principle of the invention: After the flattening machine 1 presses the furnace bars into shape, the furnace bars continuously pass through the inspection station. The upper surface of the furnace bars contacts the inspection wheel 41. When the thickness of the furnace bars is uniform, the inspection wheel 41 maintains a stable height. When the thickness of the furnace bars deviates (too thick or too thin), the inspection wheel 41 moves up and down with the undulation of the furnace bar surface.

[0026] The up-and-down movement of the detection wheel 41 causes the lifting rod 51 in contact with it to move synchronously. The lifting rod 51 slides on the support frame 3, compressing or stretching the spring 52 on it. The movement of the lifting rod 51 is transmitted through the pull rod 53 hinged to it. The middle part of the pull rod 53 is hinged to the bracket to form a lever, which converts the up-and-down movement of the lifting rod 51 into the reverse up-and-down movement of the connecting tube 62.

[0027] The connecting pipe 62 is slidably disposed inside the marking cylinder 61, and has a first through hole 63. The marking cylinder 61 has a hollow interlayer inside, and a pair of second through holes 64 are formed in the interlayer, communicating with the interlayer and the external liquid storage tank. In the initial state, the first through hole 63 on the connecting pipe 62 is located between the two second through holes 64, not aligned with any of the second through holes 64, and the liquid passage is closed.

[0028] As the connecting pipe 62 moves up or down with the movement of the detection wheel 41, the first through hole 63 aligns and connects with one of the second through holes 64. The marking liquid in the storage tank enters the interlayer of the marking cylinder 61 through the interior of the connecting pipe 62, the first through hole 63, and the second through hole 64, and is finally sprayed out from the nozzle 65 at the bottom of the marking cylinder 61, sprinkling onto the surface of the furnace grate directly below, marking the location of the abnormal thickness.

[0029] Simultaneously, as the lifting rod 51 moves, one fixed ring fixed to it and another fixed ring fixed to the support frame 3 undergo relative displacement. When the spring 52 is compressed or stretched to a set threshold (i.e., the thickness deviation exceeds the allowable range), the electrode posts 71 on the two fixed rings come into contact with each other, the circuit is turned on, and the buzzer alarm 72 is triggered to emit an audible and visual alarm, reminding the operator to pay attention to the thickness abnormality.

[0030] When the grate thickness returns to normal, spring 52 pushes lifting rod 51 and detection wheel 41 to reset, connecting pipe 62 moves in the opposite direction to misalign the first through hole 63 and the second through hole 64, marking liquid stops spraying, electrode column 71 separates, and alarm is deactivated.

[0031] This invention directly senses changes in the thickness of the furnace bars through the detection wheel 41 and uses a lever mechanism to convert the vertical displacement of the detection wheel 41 into the connection and disconnection control of the connecting pipe 62 and the marking cylinder 61. This achieves the purpose of automatically spraying liquid for marking when the thickness is abnormal and stopping marking when the thickness is normal, realizing fully automatic online thickness detection and abnormal point marking for flattened furnace bars without the need for manual visual inspection or machine stop measurement. At the same time, the two upper and lower second through holes 64 are set to cooperate with the first through hole 63 on the connecting pipe 62, so that the marking liquid can be triggered to spray out regardless of whether the furnace bar is too thick (connecting pipe 62 moves down) or too thin (connecting pipe 62 moves up), so as to effectively mark both positive and negative thickness deviations, achieving full coverage of detection marking and avoiding missed detection of unidirectional deviations. At the same time, the movement of the lifting rod 51 is linked with the electrode posts 71 on the fixing rings on both sides of the spring 52. When the thickness deviation exceeds the allowable range, a buzzer alarm is automatically triggered, so as to issue a timely warning to the operator while marking the abnormal position, realizing a dual reminder mechanism, which facilitates timely adjustment of the flattening machine 1 parameters and reduces the generation of waste.
