Description

Technical Field

[0001] This utility model relates to the technical field of profile products, and in particular to a hydraulic locking device for saw blades. Background Technology

[0002] Profiles are objects with specific geometric shapes made from iron or steel, or materials with certain strength and toughness (such as plastics, aluminum, and fiberglass), through processes such as rolling, extrusion, and casting. Classification of steel profiles: According to the different smelting quality of the steel, steel profiles are divided into ordinary steel profiles and high-quality steel profiles. Ordinary steel profiles are further divided into large steel profiles, medium steel profiles, and small steel profiles according to the current metal product catalog. Ordinary steel profiles can also be classified according to their cross-sectional shape into I-beams, channel steel, angle steel, H-beams, round steel, etc.

[0003] After hot rolling, profile products are mainly processed and collected using hot and cold sawing. The saw blades need to be replaced frequently, so the traditional physical locking method of the saw blades slows down the overall production efficiency when the saw blades are frequently replaced.

A bearing seat 3 is installed at the center of a section of the bottom outer wall of the working plate 1 located at the installation hole 2. A transmission shaft 4 is provided in the bearing seat 3. A positioning plate 5 is fixedly installed on the outer wall of one end of the transmission shaft 4. A saw blade 7 is slidably connected to the outer wall of the transmission shaft 4. A clamping structure 9 is provided at the center of the other end of the bottom outer wall of the working plate 1 located at the installation hole 2. A protective shell 10 is provided on the bottom outer wall of the working plate 1 located at the installation hole 2. The protective shell 10 protects the saw blade 7 at the bottom of the working plate 1.

[0024] The outer wall of the positioning disk 5 is provided with positioning protrusions 6 distributed at equal intervals, and the saw blade 7 is provided with positioning holes 8 at the positioning protrusions 6. The saw blade 7 is slidably connected to the outer wall of the positioning protrusions 6. The positioning protrusions 6 on the positioning disk 5 cooperate with the transmission shaft 4 to restrict and position the saw blade 7. At the same time, the positioning groove 15 on the contact disk 14 facilitates connection and clamping.

[0025] The bottom outer wall of the working plate 1 is equipped with mounting bases 11 at both ends, and the hydraulic cylinder 12 is installed in the mounting base 11. The other mounting base 11 is equipped with a drive motor 21, and the output end of the drive motor 21 is equipped with a coupling 22. The bearing seat 3, mounting base 11, stabilizing seat 18 and support rod 16 support the operation of the saw blade 7 at multiple positions to ensure the stable operation of the saw blade 7.

[0026] The drive motor 21 and the hydraulic cylinder 12 are connected to a switch via wires, and the switch is connected to a power source via wires.

[0027] Example 2:

[0028] Reference Figure 1-3 The clamping structure 9 includes a hydraulic cylinder 12, a drive cylinder 13 connected to the output end of the hydraulic cylinder 12, a contact plate 14 rotatably connected to one end of the drive cylinder 13, and a support rod 16 installed at the center of the inner wall of the drive cylinder 13. The transmission shaft 4 drives the saw blade 7 and the contact plate 14 to rotate through the positioning plate 5 and the positioning protrusion 6. The saw blade 7 rotates to work, which facilitates the replacement of the saw blade 7 and improves the replacement efficiency of the saw blade 7.

[0029] A stabilizing groove 17 is provided at the center of the outer wall of one end of the support rod 16, and the outer wall of one end of the drive shaft 4 is rotatably connected to the inner wall of the stabilizing groove 17. After the hydraulic cylinder 12 pushes the drive cylinder 13 to clamp the saw blade 7, one end of the drive shaft 4 is located in the stabilizing groove 17 of the support rod 16, ensuring the stable operation of the drive shaft 4, the saw blade 7 and the contact plate 14.

[0030] One side of the outer wall of the contact plate 14 is in contact with the outer wall of the saw blade 7, and a positioning groove 15 is provided on the outer wall of the contact plate 14 at the positioning protrusion 6, and one end of the outer wall of the positioning protrusion 6 is inserted into the positioning groove 15.

[0031] A stabilizing seat 18 is installed at one end of the outer wall of the drive cylinder 13, and a sliding protrusion 19 is welded to the top outer wall of the stabilizing seat 18. A sliding groove 20 is opened on the bottom outer wall of the working plate 1 at the stabilizing seat 18, and the sliding protrusion 19 is slidably connected to the inner wall of the sliding groove 20. During the start-up of the hydraulic cylinder 12, the stabilizing seat 18 on the drive cylinder 13 is slidably connected to the sliding groove 20 of the working plate 1 through the sliding protrusion 19, which improves the overall stability and facilitates clamping.

[0032] Working principle: When replacing the saw blade 7, the hydraulic cylinder 12 is activated to retract the drive cylinder 13. The contact plate 14 at one end of the drive cylinder 13 separates from the saw blade 7. At this time, the saw blade 7 is moved along the direction of the drive shaft 4. The saw blade 7 leaves the outer wall of the drive shaft 4 and is removed from the mounting hole 2. The new saw blade is inserted through the mounting hole 2 and passes through the outer wall of the drive shaft 4. The sliding saw blade 7 is moved to one side of the outer wall of the positioning plate 5 through the positioning hole 8. The hydraulic cylinder 12 is activated to drive the drive cylinder 13 to move in the direction of the saw blade 7. The drive cylinder 13 is rotated in advance. The contact plate 14 is brought into contact so that the positioning groove 15 on the contact plate 14 coincides with the positioning protrusion 6. Then, the drive cylinder 13 presses the saw blade 7 between the positioning plate 5 and the contact plate 14 through the contact plate 14. The drive motor 21 in the mounting base 11 starts and drives the transmission shaft 4 to rotate through the coupling 22. The transmission shaft 4 drives the saw blade 7 and the contact plate 14 to rotate through the positioning plate 5 and the positioning protrusion 6. The saw blade 7 rotates to work, which facilitates the replacement of the saw blade 7 and improves the replacement efficiency of the saw blade 7. The protective shell 10 protects the saw blade 7 at the bottom of the working plate 1.
