Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically to a high-efficiency fixed-length cutting device for bearing steel pipes. Background Technology

[0002] During the bearing manufacturing process, bearing steel tubes need to be cut to specific lengths to meet production requirements. Precise cutting to length ensures that each section of steel tube meets the dimensional standards of bearing components, greatly reducing subsequent processing allowances, reducing material waste, and improving material utilization.

[0003] When existing bearing steel pipe fixed-length cutting equipment needs to change the fixed-length specifications, it mainly relies on manual operation. Operators need to rely on experience to adjust the positioning components of the cutting device by rotating the screw and adjusting the scale to determine the new cutting length. This process is not only cumbersome, but each adjustment also requires a lot of time for measurement and calibration, which cannot efficiently perform fixed-length cutting. In addition, during long-term continuous cutting of bearing steel pipes, the friction between the cutting tool and the steel pipe generates a lot of heat. As the cutting time increases, the heat accumulates in the cutting area, causing the cutting tool temperature to rise continuously. When the tool temperature exceeds its normal operating temperature range, the hardness and wear resistance of the tool will decrease significantly, thus affecting the cutting efficiency.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a high-efficiency fixed-length cutting device for bearing steel pipes.

[0026] This utility model provides, for example Figure 1-3 The device shown is a high-efficiency fixed-length cutting device for bearing steel pipes, including a base 1, with U-shaped support seats 2 fixedly connected to both ends of the top of the base 1, a U-shaped cutting chamber 3 fixedly connected to the top of the base 1, and V-shaped placement seats 4 fixedly connected to both ends of the bottom of the base 1. Cylinders 5 are fixedly connected to the top of both ends of the U-shaped support seats 2, and the other end of the cylinder 5 passes through the side wall of the U-shaped support seat 2 and is fixedly connected to a transmission wheel device 6.

[0027] A support rod 7 is fixedly connected to the cavity of the U-shaped cutting chamber 3 via a moving mechanism. From top to bottom, a cooling spray plate device 8, an L-shaped support plate 9, and a cutting saw assembly 10 are fixedly connected to the wall of the support rod 7. A laser rangefinder 11 is fixedly connected to the side wall of the L-shaped support plate 9, and the laser rangefinder 11 corresponds to the cutting saw assembly 10. A shielding seat 12 is fixedly connected between the side walls of the U-shaped support base 2 and the base 1. A blocking baffle 13 is slidably connected inside the cavity of the shielding seat 12. A drive mechanism is fixedly connected to the blocking baffle 13 at the top of the U-shaped cutting chamber 3. The side wall of the blocking baffle 13 is fixed by an opening. A reflective rangefinder plate 14 is fixedly connected to the base 1, and an outlet 15 is opened on the top of the base 1. Using a laser rangefinder device 11 installed on the side wall of the L-shaped support plate 9, which corresponds to the position of the cutting saw assembly 10, the position of the steel pipe to be cut can be measured accurately in real time. When the fixed length specification needs to be changed, the laser rangefinder device 11 feeds the measurement data back to the control system. The control system automatically controls the moving mechanism to adjust the position of the support rod 7 according to the preset fixed length specification, thereby moving the cutting saw assembly 10 to the accurate cutting position. This process does not require manual adjustment, greatly shortening the fixed length specification adjustment time. When using, the steel pipe is placed... On the V-shaped mounting base 4, the cylinder 5 drives the transmission wheel device 6 to move the steel pipe forward. It then moves forward by contacting the blocking baffle 13 at one end. The reflective rangefinder 14 on the side wall of the blocking baffle 13, in conjunction with the laser rangefinder 11 corresponding to the position of the cutting saw assembly 10, performs measurements. The moving mechanism adjusts the position of the cutting saw assembly 10, and then the cutting saw assembly 10 performs cutting. Finally, by moving the blocking baffle 13 open, the steel pipe is again driven to the transmission wheel device 6 at the other end for unloading. Repeating these steps achieves efficient fixed-length cutting. The support rod 7 has a wall... The cooling spray plate device 8, which is fixedly connected to the upper part, continuously sprays cooling air onto the cutting part of the cutting saw assembly 10 and the steel pipe during the cutting process. This can quickly remove the heat generated by cutting, effectively reduce the temperature of the cutting tool, and keep it within the normal operating temperature range. The exhaust port 15 is used to discharge the cutting debris, which falls into the collection box or other collection tools. This solves the problems of existing bearing steel pipe fixed-length cutting devices, which are not convenient for automatically changing the fixed length specifications for efficient fixed-length cutting, and the fact that the hardness and wear resistance of the cutting tool will decrease significantly due to heat during long-term operation, thus affecting the cutting efficiency.

[0028] In order to move the support rod 7 at one end, such as Figure 1 and 2As shown, the moving mechanism includes a first electric push rod 16, a first sliding opening 17, and a support slider 18.

The side wall of the support slider 18 is fixedly connected to one end of the first electric push rod 16, and the bottom of the support slider 18 is fixedly connected to one end of the support rod 7. By using the moving mechanism composed of the first electric push rod 16, the first sliding opening 17, and the support slider 18, the support slider 18 is pushed to move in the first sliding opening 17 by the first electric push rod 16, thereby driving the support rod 7 at one end to move accordingly.

[0029] In order to move the blocking baffle 13 at one end, such as Figure 2 As shown, the driving mechanism includes a second electric push rod 19, a second sliding opening 20, and a second L-shaped support plate 21.

One end of the second L-shaped support plate 21 is fixedly connected to one end of the second electric push rod 19, and the other end of the second L-shaped support plate 21 is fixedly connected to one end of the blocking baffle 13. By using the driving mechanism composed of the second electric push rod 19, the second sliding opening 20, and the second L-shaped support plate 21, the second electric push rod 19 pushes the second L-shaped support plate 21 to move in the second sliding opening 20, thereby causing the blocking baffle 13 at one end to move accordingly.

[0030] In order to power the cooling spray plate device 8 and to move along with it when the cutting assembly moves, such as Figure 2 As shown, a cooling fan 22 is fixedly connected to one end cavity of the base 1, and an air supply hose 23 is fixedly connected to the output end of the cooling fan 22. A wiring slot 24 is opened on the side wall of the U-shaped cutting chamber 3. One end of the air supply hose 23 passes through the wiring slot 24 and is fixedly connected to the input end of the cooling spray plate device 8. The cooling fan 22 is used to supply power to the cooling spray plate device 8 through the air supply hose 23. The wiring slot 24 is used to move along with the cutting components when they move, so as not to affect the use effect.

[0031] To achieve cooling, such as Figure 2 and 3 As shown, the cooling spray plate device 8 includes a supporting hollow ring 25, and an inclined multi-hole spray plate 26 is fixedly connected to the output end of the supporting hollow ring 25. By using the cooling spray plate device 8, which consists of the supporting hollow ring 25 and the inclined multi-hole spray plate 26, and by connecting the air supply hose 23, cold air is allowed to pass through the supporting hollow ring 25 into the inclined multi-hole spray plate 26, and is sprayed onto the cutting assembly and steel pipe through the spray holes on the side wall of the inclined multi-hole spray plate 26 for cooling.

[0032] In order to simultaneously control the lifting and lowering of the cylinders 5 at both ends and to control and observe the cutting length of the device, such as Figure 1 and 2 As shown, a pneumatic control component 27 is fixedly connected to the top of the U-shaped cutting chamber 3. The output ends of the pneumatic control component 27 are fixedly connected to the cylinders 5 at both ends. A display controller 28 is fixedly connected to the side wall of the U-shaped cutting chamber 3. By using the pneumatic control component 27 and its fixed connection to the cylinders 5 at both ends, the cylinders 5 at both ends can be controlled to lift and lower simultaneously to keep them parallel to the steel pipe. By using the display controller 28, the device can be controlled and the cutting length can be observed.
