Description

Technical Field

[0001] This utility model relates to the technical field of metal cutting machines, specifically a split-type rotary shaft cutting machine. Background Technology

[0002] Centrifugal pumps work by using the rotation of an impeller to cause water to move in a centrifugal motion. Before starting the pump, the pump casing and suction pipe must be filled with water. Then, the motor is started, and the pump shaft drives the impeller and water to rotate at high speed. The water undergoes centrifugal motion and is thrown towards the outer edge of the impeller, flowing into the pump's discharge pipe through the flow channel of the volute casing.

[0003] Existing pump shaft raw materials are generally solid steel columns, which are cut to the appropriate length using a cutting machine. However, the cutting table of existing cutting machines is generally short. When cutting longer steel columns, the center of gravity of the steel column is not properly positioned. Even with clamps for fixation, the column is very prone to tilting due to the unstable center of gravity under cutting vibration, which greatly affects the cutting effect of the pump shaft. Utility Model Content

[0004] The purpose of this invention is to provide a split-type rotary cutting machine.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The machine includes a cutting machine body with a cutting working area extending through its center. A reciprocating saw blade is fixedly installed in the cutting working area. A clamp for clamping workpieces is fixedly installed on the table of the cutting machine body. A connecting block is fixedly installed at one end of the table of the cutting machine body. A conveying trough is detachably connected to the connecting block. The conveying trough is flush with the table of the cutting machine body. Telescopic support frames are fixedly installed at both ends of the conveying trough along its length.

[0007] By adopting the above technical solution, the shape of the conveying trough matches the shape of the steel column workpiece. During use, it can effectively support the center of gravity of the long strip workpiece. At the same time, the use of a telescopic support frame allows for independent adjustment of the height difference between the two ends of the conveying trough. In actual use, in conjunction with a level, the drop difference between the two ends of the workpiece can be effectively adjusted to ensure that the workpiece is horizontal for the fixture to fix. On the one hand, during cutting, it can effectively prevent the workpiece from tilting due to instability of the center of gravity, which would affect the cutting quality. On the other hand, the levelness of the long strip workpiece can be effectively adjusted by adjusting the height of the support frames at both ends, so as to achieve the effect of selecting the cutting angle according to actual needs.

[0008] Furthermore, the connecting blocks are clamped in pairs at both ends of the conveying trough, and the connecting blocks are provided with height grooves arranged along the direction of gravity. The conveying trough is provided with a pin bolt that passes through the height groove, and the end of the pin bolt is threaded with a locking nut.

[0009] By adopting the above technical solution, the connecting block is the connecting part between the conveying trough and the cutting machine body. When the conveying trough needs to be used separately, the locking nut is unscrewed and the pin bolt is pulled out of the height groove and the conveying trough to unlock it from the connecting block. At this time, the conveying trough can be separated for separate use. This is suitable for workpieces that are too long and whose center of gravity exceeds the continuous conveying trough.

[0010] Furthermore, the top wall of the conveying trough is provided with a transport trough, and the inner wall of the transport trough is provided with a number of sets of transport rollers along the length direction. The top of the transport rollers is flush with the table surface of the cutting machine body, and the top wall of the conveying trough is higher than the transport rollers.

[0011] By adopting the above technical solution, the conveyor roller uses rolling friction instead of sliding friction, which not only facilitates the loading of the workpiece before cutting, but also facilitates the continuous cutting of the workpiece by moving it continuously during the cutting process. At the same time, the top wall of the conveyor trough is higher than the conveyor roller, which can clamp and limit the workpiece on both sides to prevent the workpiece from slipping.

[0012] Furthermore, the support frame includes longitudinal frames sandwiched on both sides of the conveying trough. A transverse middle frame and a bottom frame are connected between the longitudinal frames. A lifting screw is rotatably positioned and installed through the bottom of the conveying trough. A turning bolt is fixedly connected to the side of the lifting screw that protrudes from the bottom of the conveying trough. A limiting plate that fits against the outer wall of the conveying trough is fixedly installed on the outer edge of the lifting screw. The lifting screw passes through and is threadedly connected to the middle frame. The middle frame is located in the middle of the longitudinal frames. The bottom frame is located at the bottom of the longitudinal frames. The longitudinal frames have a fitting groove along their length. A limiting block that matches the fitting groove is fixedly installed on the outer wall of the conveying trough. The bottom wall of the bottom frame has rounded corners. A ground-contacting roller is rotatably installed on the bottom wall of the bottom frame.

[0013] By adopting the above technical solution, the fitting groove and the limiting block can ensure that the two ends of the conveying trough slide strictly along the length of the longitudinal frame. At the same time, the bolt is turned by controlling the rotation of the lifting screw by the wrench. When the lifting screw rotates, the threaded engagement can control the rise or fall of one end of the conveying trough. The limiting plate can play a good limiting role without affecting the rotation of the lifting screw, ensuring a stable connection between the conveying trough and the rotating lifting screw. The rounded base frame and the ground contact roller can adaptively tilt the longitudinal frame when the conveying trough needs to be at different heights and the lengths of the two ends of the longitudinal frame are different. At the same time, the contact angle with the bottom surface is adaptively adjusted. At this time, the conveying trough is tilted, which can be used for angle cutting of workpieces or horizontal cutting of workpieces on inclined bottom surface conditions, making the application range wider.

[0014] In summary, the beneficial technical effects of this utility model are as follows:

[0015] 1. It adopts connecting blocks, conveying troughs and telescopic support frames to effectively support the center of gravity of long strip workpieces. At the same time, the telescopic support frame can independently adjust the height difference between the two ends of the conveying trough. On the one hand, it can effectively prevent the workpiece from tilting due to instability during cutting, thus affecting the cutting quality. On the other hand, the level of the long strip workpiece can be effectively adjusted by adjusting the height of the support frames at both ends, so as to achieve the effect of selecting the cutting angle according to actual needs.

[0016] 2. It adopts a height groove, pin bolt and locking nut. Unscrew the locking nut and then pull out the pin bolt from the height groove and the conveying trough to unlock it from the connecting block. At this time, the conveying trough can be separated for use in a split manner. It is suitable for workpieces that are too long and whose center of gravity exceeds the continuous conveying trough.

[0017] 3. It adopts longitudinal frames, middle frames, bottom frames and lifting screws. When the conveying trough needs different heights, the lengths of the longitudinal frames at both ends are different. The longitudinal frames will tilt adaptively and adjust the contact angle with the bottom surface. At this time, the conveying trough is tilted, which can be used for angle cutting of workpieces or horizontal cutting of workpieces on inclined bottom surfaces, making its application range wider.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-3 The present invention provides the following technical solution:

[0026] The system includes a cutting machine body 1, with a cutting work area 11 extending through its center. A reciprocating saw blade 12 is fixedly installed in the cutting work area 11. A clamping fixture 13 for holding the workpiece is fixedly installed on the table of the cutting machine body 1. A connecting block 2 is fixedly installed at one end of the table of the cutting machine body 1. A conveying trough 3 is detachably connected to the connecting block 2. The conveying trough 3 is flush with the table of the cutting machine body 1. Telescopic support frames 4 are fixedly installed at both ends of the conveying trough 3 along its length. The shape of the conveying trough 3 matches the shape of the steel column workpiece. During use, it can effectively support the center of gravity of the long strip workpiece. At the same time, the telescopic support frame 4 can independently adjust the height difference between the two ends of the conveying trough 3. In actual use, in conjunction with a level, it can effectively adjust the drop difference between the two ends of the workpiece to ensure that the workpiece is horizontal for the clamping fixture 13 to fix. On the one hand, it can effectively prevent the workpiece from tilting due to instability during cutting, thus affecting the cutting quality. On the other hand, the horizontality of the long strip workpiece can be effectively adjusted by adjusting the height of the support frames 4 at both ends, so as to achieve the effect of selecting the cutting angle according to actual needs.

[0027] Connecting blocks 2 are clamped in pairs at both ends of the conveying trough 3. The connecting blocks 2 have a height groove 21 arranged along the direction of gravity. The conveying trough 3 is movably connected with a pin bolt 22, which passes through the height groove 21. The end of the pin bolt 22 is threaded with a locking nut 23. The connecting blocks 2 are the connecting parts between the conveying trough 3 and the cutting machine body 1. When the conveying trough 3 needs to be used separately, the locking nut 23 is unscrewed and the pin bolt 22 is pulled out of the height groove 21 and the conveying trough 3 to unlock it from the connecting blocks 2. At this time, the conveying trough 3 can be separated for separate use. This is suitable for workpieces that are too long and whose center of gravity exceeds the continuous conveying trough 3.

[0028] The top wall of the conveying trough 3 is provided with a transport trough 31. Several sets of transport rollers 32 are arranged along the length of the inner wall of the transport trough 31. The top of the transport rollers 32 is flush with the table surface of the cutting machine body 1. The top wall of the conveying trough 3 is higher than the transport rollers 32. The transport rollers 32 use rolling friction instead of sliding friction, which not only facilitates the loading of the workpiece before cutting, but also facilitates the continuous movement of the workpiece for continuous cutting during the cutting process. At the same time, the top wall of the conveying trough 3 is higher than the transport rollers 32, which can clamp and limit the workpiece on both sides to prevent the workpiece from slipping.

[0029] The support frame 4 includes longitudinal frames 41 clamped on both sides of the conveying trough 3. A transverse middle frame 42 and a base frame 43 are connected between the longitudinal frames 41. A lifting screw 44 is rotatably mounted through the bottom of the conveying trough 31. A tightening bolt 45 is fixedly connected to one side of the lifting screw 44 extending out of the bottom of the conveying trough 31. A limiting plate 46, conforming to the outer wall of the conveying trough 3, is fixedly mounted on the outer edge of the lifting screw 44. The lifting screw 44 passes through and is threadedly connected to the middle frame 42, which is located in the middle of the longitudinal frames 41. The base frame 43 is located at the bottom of the longitudinal frames 41. A fitting groove 47 is formed along the length of the longitudinal frames 41. A limiting block 48, matching the fitting groove 47, is fixedly mounted on the outer wall of the conveying trough 3. The bottom wall of the base frame 43 has rounded corners. A ground-contacting roller 49 is rotatably mounted on the bottom wall of the base frame 43. The fitting groove 47, in conjunction with the limiting block 48, allows for... To ensure that the two ends of the conveyor trough 3 slide strictly along the length of the longitudinal frame 41, the bolt 45 is turned by a wrench during use, thereby controlling the rotation of the lifting screw 44. When the lifting screw 44 rotates, the threaded connection can control one end of the conveyor trough 3 to rise or fall. The limiting plate 46 can not only affect the rotation of the lifting screw 44, but also play a good limiting role, ensuring a stable connection between the conveyor trough 3 and the rotating lifting screw 44. The rounded base frame 43, together with the ground roller 49, will adaptively tilt when the conveyor trough 3 needs different heights and the lengths of the two longitudinal frames 41 are different. At the same time, it will adaptively adjust the contact angle with the bottom surface. At this time, the conveyor trough 3 is tilted, which can be used for angle cutting of workpieces or horizontal cutting of workpieces on inclined bottom surface conditions, making its application range wider.
