Description

Technical Field

[0001] The present invention relates to the technical field of sawing machines, and mainly relates to a sawing machine for producing crystallizer copper tubes. Background Art

[0002] A sawing machine is a machine tool for cutting metal materials, generally used for cutting various alloy steels. The applicable range of the sawing machine is very wide, and the sawing machine is required in any industry with cutting needs. A sawing machine generally includes a base, a bed, a feeding rack, a discharging rack, a large column tube, a square column lead frame, a lifting cylinder, a saw frame, a saw band guiding device, a speed reducer, and a driving and driven pulley, etc. Its feeding rack and discharging rack are usually assembled by channel steel, bearings, rollers, etc., and materials are placed thereon for conveying; its base is usually a box-type structure welded by steel plates, used for fixing the bed and the column tube, playing a supporting role; its large column tube is usually a guide rail for the movement of the saw frame, used for supporting the saw frame to perform lifting movement; its bed is usually a casting, cast by a mold, with a clamp thereon, used for fixing the saw band and materials; its clamp cylinder can use hydraulic pressure to make the movable clamp move, so as to achieve the purpose of fixing materials; its square column lead frame can be used to assist the saw frame to perform lifting movement, ensuring normal cutting of the saw band; its lifting cylinder can use hydraulic pressure to support the saw frame to perform lifting movement to achieve the cutting purpose; its saw frame is usually formed by cutting and welding a rear steel plate, with strong rigidity, and performs cutting work through its lifting movement; its saw band guiding device can be used to change the installation angle of the saw band, ensure that the saw band is perpendicular to the workbench, ensure cutting accuracy, and reduce vibration; its speed reducer usually provides power for the driving pulley to drive the saw band to perform cutting work; its driving and driven pulley cover can prevent the driving and driven pulleys from being exposed outside, causing harm to the staff, playing a protective role.

[0003] When the existing sawing machine cuts the crystallizer copper tube, there are usually some problems. Since the crystallizer copper tube is a square or rectangular copper tube that is slightly bent to one side, when cutting it, it is usually placed with its arc convex surface facing downwards. Therefore, there will be a certain arc gap between the bottom of the crystallizer copper tube and the bed. In this way, under the action of force during cutting, the crystallizer copper tube will tend to collapse downward at the front side and tilt upward at the rear side, thus affecting its cutting accuracy and making it inconvenient for cutting; and because the crystallizer copper tube is heavy, when cutting it, usually after one material is cut, another uncut crystallizer copper tube needs to be moved to the feeding rack by a gantry crane, and then re-clamped for cutting. In this way, it takes a long time and has low efficiency, and cannot better meet its cutting requirements. Summary of the Invention

[0004] The present invention provides a sawing machine for producing crystallizer copper tubes to solve the technical problem that the existing sawing machine cannot cut the crystallizer copper tube well as mentioned in the above background art.

[0005] To achieve the above object, the present invention adopts the following technical solutions: A sawing machine for producing crystallizer copper tubes, comprising a base and a bed. The bed is located on the base. In the middle of the upper surface of the bed, a transverse chute is correspondingly provided. On both sides of the top of the chute, fixed clamps are correspondingly provided. In the chute, a movable clamp capable of moving horizontally is correspondingly provided. On both sides of the movable clamp, clamping surfaces are provided. On the front and rear sides of the chute on the bed, liftable support plates are symmetrically provided. The support plates can be retracted into the bed, and proximity switches are correspondingly embedded in the tops of the support plates.

[0006] Preferably, on the front and rear sides of the chute on the bed, two groups of support plate receiving grooves are symmetrically provided. The two groups of support plate receiving grooves are symmetrically arranged left and right. The support plates are correspondingly located in the support plate receiving grooves. At the bottom of the support plate receiving groove, a telescopic cylinder mounting groove is correspondingly provided. In the telescopic cylinder mounting groove, a telescopic cylinder is correspondingly mounted. The telescopic end of the telescopic cylinder is connected to the support plate, and the support plate is controlled to extend by the telescopic cylinder.

[0007] Preferably, on one side of the bed, a clamp cylinder is correspondingly provided. The telescopic end of the clamp cylinder is correspondingly connected to the bottom of the movable clamp, and the movable clamp is driven to move horizontally by the clamp cylinder.

[0008] Preferably, on both sides of the bed, side support plates are correspondingly provided. The clamp cylinder is correspondingly mounted on one side support plate, and the telescopic end of the clamp cylinder passes through the side support plate and is correspondingly connected to the bottom of the movable clamp.

[0009] Preferably, the proximity switch and the telescopic cylinder are correspondingly connected to the control system. When the crystallizer copper tube moves to the corresponding position for cutting, the telescopic cylinder controls the support plate to extend until the proximity switch on it senses the crystallizer copper tube and transmits its signal to the control system, and the control system will control the corresponding telescopic cylinder to stop working.

[0010] Preferably, the sawing machine further includes a discharge rack and a feeding rack. The discharge rack and the feeding rack are respectively located on the front and rear sides of the base. On the discharge rack, a horizontally movable roller rack capable of lifting is correspondingly provided.

[0011] Preferably, the horizontally movable roller rack includes a fixed rack and a lifting rack. The fixed rack is correspondingly mounted on the rack body of the discharge rack. The lifting rack is liftably mounted on the fixed rack. On the lifting rack, multiple rows of rotatable rollers are provided at intervals. Each row of rollers is correspondingly located between two adjacent discharge rollers on the discharge rack.

[0012] Preferably, multiple lifting cylinders are correspondingly mounted in the fixed rack. The telescopic ends of the lifting cylinders are correspondingly connected to the lifting rack, and the lifting of the lifting rack is controlled by the lifting cylinders.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The present invention symmetrically provides liftable support plates on the front and rear sides of the slideway on the bed, uses a telescopic cylinder to control the lifting of the support plates, and has a proximity switch embedded in the top of the support plates. By providing the support plates, telescopic cylinders and proximity switches, and correspondingly connecting the proximity switches and telescopic cylinders to the control system, when the crystallizer copper tube moves to the corresponding position to prepare for cutting, the telescopic cylinder controls the support plate to extend until the proximity switch on it senses the crystallizer copper tube and transmits its signal to the control system, and the control system controls the corresponding telescopic cylinder to stop working, so that the support plates on both sides of the slideway can fit the bottom arc convex surface of the crystallizer copper tube and play a supporting role. In this way, if the crystallizer copper tube is clamped for cutting, it can better avoid the front side of the crystallizer copper tube collapsing downward and the rear side tilting upward, which is convenient for cutting and better ensures its cutting accuracy. In addition, the support plate can be correspondingly retracted into the bed, so as not to affect the sawing machine to cut other workpieces, and its application range is relatively wide.

[0015] In addition, the present invention provides fixed clamps on the top of the left and right sides of the chute, and clamping surfaces on the left and right sides of the movable clamp. The movable clamp is driven to move by the clamp cylinder, and the left and right sides of the movable clamp cooperate with the fixed clamp to clamp the crystallizer copper tube. In this way, two crystallizer copper tubes to be cut can be placed on both sides of the feeding rack when in use. After the crystallizer copper tube clamped on one side of the movable clamp is cut, the other side of the movable clamp can be immediately switched to clamp the other uncut crystallizer copper tube and cut. Compared with the traditional cutting method, the cutting efficiency is effectively improved so as to better meet the cutting needs. The discharging rack is provided with a lifting horizontal roller rack. By providing the horizontal roller rack, the cut crystallizer copper tube can be automatically moved to both sides of the discharging rack, which not only vacates the position for the subsequent material cutting, but also facilitates the staff to unload the material.

The bed 2 is correspondingly located on the base 1. The discharge rack 4 and the feeding rack 3 are respectively located on the front and rear sides of the base 1. The saw frame can perform cutting work through its lifting movement. The lifting cylinder can use hydraulic pressure to support the saw frame for lifting movement. The large column tube is used to support the saw frame for lifting movement. The square column lead frame is used to assist the saw frame for lifting movement. The saw band guiding device can be used to change the installation angle of the saw band to ensure that the saw band is perpendicular to the workbench and ensure the cutting accuracy. The speed reducer can provide power to the driving pulley to drive the saw band to perform cutting work. The main and driven pulley cover can prevent the main and driven pulleys from being exposed outside and causing harm to the staff, playing a protective role (the general structure of the sawing machine of the present invention is generally the same as that of the existing sawing machine, that is, the specific installation and its implementation principle of components such as its large column tube, square column lead frame, lifting cylinder, saw frame, saw band guiding device, speed reducer, and main and driven pulley are all prior arts, so they will not be specifically described here).

[0025] A transverse chute 201 is correspondingly provided in the middle of the upper surface of the bed 2. Fixed clamps 6 are correspondingly provided at the tops of the left and right sides of the chute 201. A movable clamp 7 that can move horizontally is correspondingly provided in the chute 201. Clamping surfaces are provided on both the left and right sides of the movable clamp 7. A clamp cylinder 8 is correspondingly provided on one side of the bed 2. Side support plates 9 are correspondingly provided on both sides of the bed 2. The clamp cylinder 8 is correspondingly installed on the side support plate 9 on one side. The telescopic end 801 of the clamp cylinder 8 passes through the side support plate 9 and is correspondingly connected to the bottom of the movable clamp 7, and the movable clamp 7 is driven to move horizontally by the clamp cylinder 8. Through grooves are correspondingly provided in the middles of the fixed clamp 6, the movable clamp 7, and the side support plate 9 so that the saw band 5 can fall to cut the mold copper tube 14. In the present invention, clamping surfaces are provided on both the left and right sides of the movable clamp 7. The movable clamp 7 is driven to move by the clamp cylinder 8. The mold copper tube 14 can be clamped by the cooperation of the left and right sides of the movable clamp 7 and the fixed clamp 6. In this way, when in use, two mold copper tubes 14 to be cut can be correspondingly placed on both sides of the feeding rack 3. After one mold copper tube 14 clamped on one side of the movable clamp 7 is cut, it can be immediately switched to the other side of the movable clamp 7 to clamp the other uncut mold copper tube 14 and perform cutting. In this way, compared with the traditional cutting method, the cutting efficiency is effectively improved, so as to better meet its cutting requirements.

[0026] On the front and rear sides of the chute 201 on the bed 2, symmetrically arranged are liftable support plates 11 which can be retracted into the bed 2, and proximity switches 12 are correspondingly embedded in the tops of the support plates 11. Specifically, on the front and rear sides of the chute 201 on the bed 2, symmetrically arranged are two groups of support plate receiving grooves 202, and the two groups of support plate receiving grooves 202 are symmetrically arranged left and right. The support plates 11 are correspondingly located in the support plate receiving grooves 202. At the bottom of the support plate receiving groove 202, correspondingly arranged are two telescopic cylinder mounting grooves 203, and telescopic cylinders 10 are correspondingly installed in the telescopic cylinder mounting grooves 203. The telescopic ends of the telescopic cylinders 10 are connected to the support plates 11, and the support plates 11 are controlled to extend by the telescopic cylinders 10. A protective pad can be correspondingly arranged on the upper surface of the support plates 11. Both the proximity switches 12 and the telescopic cylinders 10 are correspondingly connected to the control system. When the crystallizer copper tube 14 moves to the corresponding position for cutting, the telescopic cylinders 10 control the support plates 11 to extend until the proximity switches 12 thereon sense the crystallizer copper tube 14 and transmit their signals to the control system. Then the control system will control the corresponding telescopic cylinders 10 to stop working, so that the support plates 11 on both sides of the chute 201 can fit the bottom convex surface of the crystallizer copper tube 14 and play a supporting role. In this way, when the crystallizer copper tube 14 is clamped for cutting, it can better avoid the front side of the crystallizer copper tube 14 from sagging downward and the rear side from tilting upward, which is convenient for its cutting and can better ensure its cutting accuracy. Moreover, the support plates 11 can be correspondingly retracted into the bed 2, thus not affecting the cutting of other workpieces by this sawing machine, and its application range is relatively wide.

[0027] On the discharge rack 4, correspondingly arranged is a liftable transverse roller rack 13. Specifically, the transverse roller rack 13 includes a fixed rack 1301 and a lifting rack 1302. The fixed rack 1301 is correspondingly installed on the rack body of the discharge rack 4, and the lifting rack 1302 is liftably installed on the fixed rack 1301. Inside the fixed rack 1301, correspondingly installed are a plurality of lifting cylinders, and the telescopic ends of the lifting cylinders are correspondingly connected to the lifting rack 1302. The lifting of the lifting rack 1302 is controlled by the lifting cylinders. On the lifting rack 1302, multiple rows of rotatable rollers 1303 are arranged at intervals, and each row of rollers 1303 is correspondingly located between two adjacent discharge rollers on the discharge rack 4. During use, the lifting rack 1302 can be lifted so that the tops of the rollers 1303 thereon are higher than the tops of the discharge rollers on the discharge rack 4. At this time, after the crystallizer copper tube 14 is cut, it will automatically move to both sides of the discharge rack 4 under the rotation of the rollers 1303, which not only vacates the position for the cutting of subsequent materials but also facilitates the staff to unload the materials.
