Description

A roll biting and notching device under TMCP process conditions

Technical Field

The utility model belongs to the technical field of steel rolling collars in the steel industry, and in particular relates to a roller biting notching device under TMCP process conditions.

Background technique

At present, the holeless rolling mills used in the steel industry and bar production lines have difficulty in biting the rolled pieces because the side length of the continuous casting billet reaches 165mm. Generally, the method of increasing the friction angle is used to improve the biting state. The methods to improve the biting state include: surfacing welding on the roll surface and grinding with a grinding wheel on the roll surface. However, surfacing welding on the roll surface will affect the product quality, and grinding with a grinding wheel will increase the labor and the effect is not good. According to literature records, the method of using a reasonably designed roll notch can improve the biting state without affecting the product quality.

The Chinese patent with the publication number CN 205996208 U discloses a scoring device for roller bite under TMCP process conditions, including a chuck, a gear, a connecting rod, a universal shaft, a cam, a tool holder, and a tool; a gear is installed on the lathe chuck so that the center line of the gear coincides with the rotation center of the lathe, the gear includes gear I and gear II, a connecting rod is arranged at the central through hole of gear II, the connecting rod slides freely along the axial direction in gear II, a universal shaft is arranged at one end of the connecting rod, and a cam is arranged adjacent to the universal shaft, the rotation of the lathe spindle is transmitted to the connecting rod through gear II, and then transmitted to the cam through the universal shaft, the tool is always close to the cam through a spring, the tool is installed on the lathe tool holder, and the cam and the tool holder are fixed on the lathe large pallet. The device is to make the tool cut the roller intermittently through the groove on the cam, form intermittent scoring in the circumferential direction, then slide the connecting rod to move the tool, and then cut again to form another new scoring until the intermittent scoring fills the entire roller surface. This scoring method is inefficient and requires multiple tool movements and continuous shut-down and start-up for scoring. In addition, the intermittent scoring causes uneven friction when the roll bites into the rolled steel during operation, resulting in unstable bite and poor bite effect. When a turning tool is used for scoring, the tool head is easily worn, which is a consumable part and increases production costs. Burrs are easily generated on the cutting edge, affecting product quality.

Therefore, a roll biting notching device under TMCP process conditions is proposed.

Preferably, the clamping mechanism includes a three-jaw chuck and a center, and the three-jaw chuck and the center are respectively fixed to two side walls of the frame.

Compared with the prior art, the utility model has the following advantages and technical effects:

When in use, the roller is first fixed to the clamping mechanism, and the clamping mechanism can make the roller rotate along the axis. The motor is started by the control center, and the motor can rotate forward and backward. The forward or reverse rotation of the motor can drive the screw to rotate. Since the slider is threadedly connected to the screw, and there is a guide rod to limit the rotation of the slider, when the screw rotates, it drives the slider forward or backward along the screw. First, the slider is translated to the top of the end of the roller, so that the laser transmitter fixed under the slider corresponds to the end of the roller, and then the motor, laser transmitter and clamping mechanism are controlled to start at the same time by the control center. The motor rotates forward to make the slider move from the roller to the roller. One end of the roller moves to the other end, while the clamping mechanism clamps the roller to rotate, and the laser emitter continuously emits laser to score the surface of the roller. The various structural parts cooperate with each other, so that the laser emitter forms a spiral score on the surface of the roller; then the slider, i.e., the initial position of the laser emitter, is adjusted through the control center, and the above operation is repeated to form multiple spiral scores; after repeating several times, the initial position is set to the other end of the roller, and the motor is rotated in the opposite direction, correspondingly forming symmetrical reverse spiral scores, which intersect with the above forward spiral scores to form a continuous mesh pattern. The roller biting scoring equipment under the TMCP process conditions of the present application forms continuous spiral scores from one end of the roller to the other end, and the score scored at one time is longer and has a larger area, so the number of repeated starts and stops of the equipment for scoring is less, and the forward and reverse spiral scores intersect with each other to form a mesh score, and the structure is symmetrical. Therefore, when the roller produced by the present application bites into the steel rolling, the friction force is uniform, which makes the biting smooth and causes less wear on the roller. The present application adopts a laser transmitter to score the surface of the roller, and the laser engraving has high precision, good depth control, less burrs and high scoring quality.

Detailed ways

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

1-4, the present embodiment provides a roller biting notching device under TMCP process conditions, including: a frame 1, with clamping mechanisms for fixing the roller 2 fixedly connected to both sides of the middle part of the frame 1, a guide rod 3 fixedly connected to the top of the frame 1, and a screw rod 4 correspondingly arranged below the guide rod 3, the screw rod 4 is rotatably connected to the two side walls of the frame 1, and one end of the screw rod 4 passes through the side wall of the frame 1 and is transmission-connected to a motor 5; a slider 6 is threadedly connected to the screw rod 4, and the end of the slider 6 away from the screw rod 4 is slidably connected to the guide rod 3; a laser emitter 7 is fixedly connected to the bottom of the slider 6, and a control center 8 is fixedly connected to one side of the frame 1, and the control center 8 is electrically connected to the clamping mechanism and the motor 5.

When in use, first fix the roller 2 to the clamping mechanism, the clamping mechanism can make the roller 2 rotate along the axis, start the motor 5 through the control center 8, the motor 5 can rotate forward and reverse, the forward or reverse rotation of the motor 5 can drive the screw 4 to rotate, because the slider 6 is threadedly connected to the screw 4, and the guide rod 3 is used to limit the rotation of the slider 6, so when the screw 4 rotates, it drives the slider 6 to move forward or backward along the screw 4, first translate the slider 6 to the top of the end of the roller 2, so that the laser transmitter 7 fixed to the bottom of the slider 6 corresponds to the end of the roller 2, and then the control center 8 controls the motor 5, the laser transmitter 7 and the clamping mechanism to start at the same time, and the motor 5 rotates forward. The slider 6 is moved from one end of the roller 2 to the other end, and the clamping mechanism clamps the roller 2 to rotate, while the laser emitter 7 continuously emits laser to score the surface of the roller 2. The various structural parts cooperate with each other, so that the laser emitter 7 forms a spiral score on the surface of the roller 2; then the initial position of the slider 6, i.e., the laser emitter 7, is adjusted by the control center 8, and the above operation is repeated to form a plurality of spiral scores; after repeating several times, the initial position is set to the other end of the roller 2, and the motor 5 is rotated in the reverse direction to form a symmetrical reverse spiral score, which intersects with the above forward spiral score to form a continuous mesh pattern. The roller biting scoring equipment under the TMCP process conditions of the present application forms a continuous spiral scoring from one end of the roller 2 to the other end. The scoring is longer and has a larger area. Therefore, the number of times the equipment needs to be repeatedly started and stopped for scoring is less, and the positive and negative spiral scorings intersect each other to form a mesh scoring with a symmetrical structure. Therefore, when the roller 2 produced by the present application bites into the rolled steel, the friction force is uniform, the biting is smooth, and the wear on the roller 2 is small. The present application uses a laser transmitter 7 to score the surface of the roller 2. The laser engraving has high precision, good depth control, fewer burrs, and high scoring quality.

According to a further optimized solution, the slider 6 and the laser transmitter 7 are fixedly connected via a telescopic rod 9 , and the telescopic rod 9 is electrically connected to the control center 8 .

The distance between the laser emitter 7 and the roller 2 can be adjusted by the telescopic rod 9, which can adapt to rollers 2 of different diameters on the one hand, and adjust the accuracy of the notch by adjusting the height at which the laser is generated on the other hand.

A further optimized solution is that the front of the frame 1 is open, a roller shutter roller 10 is fixedly connected to the top front end of the frame 1, a roller shutter 11 is wound inside the roller shutter roller 10, and the roller shutter 11 is made of a transparent flexible material. After the roller shutter 11 is stretched, the length and width dimensions are the dimensions of the front of the frame 1.

The front of the frame 1 is open for operators to observe the internal working conditions in real time. The setting of the roller shutter 11 can prevent the dust generated during the notching from floating out of the frame 1 and causing harm to the human body; at the same time, opening the roller shutter 11 does not affect the installation and removal of the roller 2.

The roller shutter 11 is preferably made of fireproof PVC material.

The internal structure of the roller shutter drum 10 is the same as the structure of the roller shutter door 11, which is prior art and will not be described in detail here.

According to a further optimized solution, flexible magnetic strips 13 are fixedly connected to both sides of the rolling curtain 11 ; and magnetic attraction strips 12 are fixedly connected to both sides of the front of the frame 1 corresponding to the flexible magnetic strips 13 .

The flexible magnetic strip 13 is preferably a rubber magnetic strip, and the magnetic strip 12 is preferably an iron sheet or a magnet; when the roller blind 11 is pulled down, the flexible magnetic strip 13 is adsorbed on the magnetic strip 12, sealing the two sides of the roller blind 11 and the frame 1 to prevent dust leakage, thereby protecting the health of the staff and the sanitation of the working environment.

According to a further optimized solution, a support bar 14 is provided at the bottom of the rolling curtain 11 , and a handle 15 is fixedly connected below the support bar 14 .

The support bar 14 supports the shape of the soft rolling curtain 11 , and the handle 15 facilitates the staff to pull up or pull down the rolling curtain 11 .

As a further optimization scheme, hanging rings 16 are fixedly connected to the bottom of both sides of the rolling curtain 11, and hooks 17 are provided below the magnetic strip 12 corresponding to the hanging rings 16. The hooks 17 are bent downward, and the side ends are fixedly connected to the frame 1.

To prevent the rolling curtain 11 from automatically rolling up, the operator holds the handle 15 and pulls down the rolling curtain 11, and then hangs the hanging loops 16 at both ends of the rolling curtain 11 on the hooks 17 at the bottom of the frame 1. The rolling curtain 11 has a force to roll up by itself, so that the hanging loops 16 are hung on the hooks 17 and do not get loose. When removing the hanging loops 16 from the hooks 17, the operator only needs to hold the handle 15 and pull the rolling curtain 11 downward to make the hanging loops 16 fall off the hooks 17, and then release the handle 15 or slowly move it up to roll up the rolling curtain 11.

According to a further optimized solution, a receiving box 18 is slidably connected to the bottom of the frame 1 .

The receiving box 18 can receive the falling dust and can be drawn out for cleaning.

According to a further optimized solution, the clamping mechanism includes a three-jaw chuck 19 and a center 20 , and the three-jaw chuck 19 and the center 20 are respectively fixed to the two side walls of the frame 1 .

The three-jaw chuck 19 grabs one end of the roller 2, and the top 20 presses the other end of the roller 2 tightly to fix the roller 2. The three-jaw chuck 19 rotates to drive the roller 2 to rotate.

Furthermore, the three-jaw chuck is preferably a pneumatic rotary chuck, which rotates and clamps the chuck by air pressure and is controlled by the control center 8. Compared with a manual chuck, it has a high degree of automation, high precision and high efficiency.
