Technical Field

[0001] This utility model relates to the field of prefabricated buildings, and in particular to a cutting device for prefabricated house frame components. Background Technology

[0002] The keel components of prefabricated houses are usually made of light steel C-shaped, U-shaped or Ω-shaped cold-formed thin-walled steel, which are continuously formed by a special roll forming production line and then cut to a fixed length according to the design length.

[0003] Existing cutting devices are mostly fixed structures, and the positions of their base and cutting mechanism are not adjustable, making it impossible to flexibly and accurately correspond to the discharge position of the upstream keel production device and the changes in the width and height of different specifications of keels.

[0004] During the production of keel, manual repeated measurement, padding, or temporary fixation are required. The adjustment process is cumbersome and has low precision, resulting in uneven stress on the keel components during the cutting process. This can easily lead to problems such as side bending, twisting, burrs on the cut, or deformation of the end face, which seriously affects the assembly accuracy and structural safety of the components.

[0005] Meanwhile, the existing equipment's cutting seat and blades are mostly designed as a single unit. When changing different keel cavity lower molds, the entire equipment needs to be disassembled, resulting in long downtime and making it difficult to meet the production needs of rapid switching between multiple keel specifications.

[0006] Therefore, it is necessary to further improve the cutting device for prefabricated house keel components. Utility Model Content

[0027] Please see Figure 1-4 This utility model provides a technical solution: a cutting device for prefabricated house keel components, including a base plate 1. A dovetail slide rail 16 is fixedly provided on the upper surface of the base plate 1 along the longitudinal direction of the base 8. The base 8 is slidably installed on the dovetail slide rail 16. The bottom of the base 8 is provided with a dovetail groove that matches the dovetail slide rail 16. The base 8 is fixedly connected to the base plate 1 by a fixing bolt group 3. The fixing bolt group 3 passes through a strip groove 2 opened in the middle of the base 8. The strip groove 2 is a through groove extending along the adjustable direction of the base 8, allowing the fixing bolt group 3 to be locked after the position of the base 8 is adjusted along the length of the groove.

[0028] Vertical plates 9 are fixedly installed on the left and right sides of the base plate 1. Horizontal mounting holes are symmetrically opened on the vertical plates 9. Adjustment components 11 are fixedly installed in the holes. The adjustment components 11 contact the two sides of the base 8 through the rotating components 10.

[0029] A rectangular mounting groove is provided in the middle of the rear side of the base 8. An angular positioning strip 12 is fixedly installed in the mounting groove. The angular positioning strip 12 is an angular cross-section steel strip that extends along the depth direction of the mounting groove. A cutting seat 15 is detachably installed in the mounting groove through a fixing component 14. An angular positioning groove is provided on the outer side of the cutting seat 15 to cooperate with the angular positioning strip 12. The angular positioning strip 12 fits snugly with the angular positioning groove to achieve precise positioning of the cutting seat 15 in the vertical direction.

[0030] The front side of the base 8 is symmetrically fixed with L-shaped fixing strips 7. The L-shaped fixing strips 7 are inverted and form a tool guide groove with the gap between them and the base 8. The middle part of the die-cutting blade 6 has a tool groove with the same shape as the cutting seat 15. The keel is discharged through the cutting seat 15 and the die-cutting blade 6. When the die-cutting blade 6 moves obliquely, it can be obliquely die-cut.

[0031] The base 8 is movably assembled with the die-cutting blade 6 via the limiting component 4. The limiting component 4 includes limiting grooves 401 formed on both sides of the die-cutting blade 6 and limiting posts 402 fixed on the base 8. The limiting posts 402 extend into the limiting grooves 401. The limiting grooves 401 are oblique elongated grooves that are consistent with the moving direction of the die-cutting blade 6. The width of the limiting grooves 401 is slightly larger than the diameter of the limiting posts 402, forming a clearance fit, which only allows the die-cutting blade 6 to reciprocate along the direction of the limiting grooves 401.

[0032] A connecting frame 13 is fixedly installed in the middle of the upper surface of the base 8. A telescopic component 5 is fixedly connected to the top of the connecting frame 13. The telescopic end of the telescopic component 5 is connected to the upper end of the die-cutting blade 6.

[0033] The fixing component 14 includes an mounting strip 1402 and connecting bolts 1401. The base 8 and the cutting seat 15 are symmetrically provided with connecting grooves. The mounting strip 1402 is a rectangular steel strip that spans across the two connecting grooves. The mounting strip 1402 is threadedly connected to the base 8 and the cutting seat 15 by two sets of connecting bolts 1401, respectively, so as to realize the quick assembly and disassembly of the cutting seat 15.

[0034] In the limiting component 4, the limiting groove 401 is a rectangular groove symmetrically machined on both sides of the die-cutting blade 6, and the limiting post 402 is a cylindrical steel pin, one end of which is pressed into or threaded to the side wall of the base 8, and the other end extends into the limiting groove 401. The clearance fit is 0.1-0.2mm to ensure that the die-cutting blade 6 does not produce horizontal wobble during high-frequency reciprocating motion.

[0035] The telescopic assembly 5 includes a connecting plate 501, an electric telescopic rod 502, and a connector 503. The connecting plate 501 is horizontally fixed to the top of the connecting frame 13, and the electric telescopic rod 502 is vertically installed on the connecting plate 501. Its telescopic end is connected to the upper end of the die-cutting blade 6 through the connector 503. The connector 503 adopts a pin shaft and T-shaped structure, allowing a slight angular deflection to compensate for installation errors.

[0036] The adjustment assembly 11 includes a handle 1101, an adjustment bolt 1102, and a nut seat 1103. The nut seat 1103 is a trapezoidal threaded copper sleeve with a flange, which is fixedly installed in the horizontal mounting hole of the vertical plate 9. The adjustment bolt 1102 is threadedly engaged with the nut seat 1103. The handle 1101 is fixed to the outer end of the adjustment bolt 1102 by a flat key. The rotating assembly 10 is fixedly installed to the inner end of the adjustment bolt 1102.

[0037] The rotating assembly 10 includes a rotating seat 1001 and ball bearings 1002. The rotating seat 1001 is threaded to the end of the adjusting bolt 1102. An annular mounting groove is opened on its end face. Multiple ball bearings 1002 are distributed in the mounting groove by a cage array. The ball bearings 1002 can be made of GCr15 bearing steel with a diameter of 5mm. The outer tangent of the ball bearings 1002 makes rolling contact with the side wall of the base 8.

[0038] The base plate 1 and the upright plate 9 are welded from Q235B steel plates with a thickness of not less than 10mm and hot-dip galvanized. The dovetail slide rail 16 is made of 45# steel and quenched to a hardness of HRC45-50. The cutting seat 15 and the L-shaped fixing strip 7 are made of 40Cr alloy steel with heat treatment. The die-cutting blade 6 has YG8 hard alloy inlaid on the cutting edge with a hardness of HRA89 or higher. The mounting strip 1402 and the connecting bolt 1401 are made of 8.8 grade high-strength steel.

[0039] The working principle and usage method of this utility model are as follows: First, push the cutting seat 15 into the mounting groove of the base 8 so that the angle positioning strip 12 is completely attached to the angle positioning groove, put in the mounting strip 1402 and tighten the connecting bolts 1401 on both sides to complete the fixing of the cutting seat 15.

[0040] According to the shape requirements of the keel component to be processed, slide the base 8 along the dovetail slide rail 16 to the appropriate position, rotate the handles 1101 on both sides, drive the adjusting bolt 1102 to move forward through the nut seat 1103, and the ball 1002 of the rotating component 10 rolls to contact the side wall of the base 8. When the adjusting bolt 1102 on one side is tightened, the adjusting bolt 1102 on the other side needs to be rotated in the opposite direction to adjust the position of the base 8, ensuring that the cutting seat 15 is aligned with the discharge position of the keel extrusion forming machine. After the position is aligned, tighten all the adjusting bolts 1102 on both sides to clamp the base 8, and tighten the fixing bolt group 3 to lock the base 8.

[0041] The prefabricated house keel component (C-shaped, U-shaped, or Ω-shaped light steel keel) to be cut is placed in the cavity of the cutting seat 15, with its front end protruding from the cavity of the die-cutting knife 6. The electric telescopic rod 502 is activated, and its telescopic end pushes the die-cutting knife 6 downward. The die-cutting knife 6 moves downward under the constraint of the tool guide groove of the L-shaped fixing strip 7 and the limiting component 4. The die-cutting knife 6 and the cutting seat 15 form a shearing engagement to complete the precise cutting of the keel component.

[0042] After cutting is completed, the electric telescopic rod 502 retracts, and the die-cutting blade 6 moves upward to reset. The cut workpiece can then be removed to start the next cycle.

[0043] This utility model achieves position adjustment of the base 8 by cooperating with the dovetail slide rail 16 and the strip groove 2, and achieves high-precision adjustment and clamping fixation by combining the adjustment component 11 and the rotation component 10; the cutting seat 15 adopts a detachable connection between the angled positioning strip 12 and the fixing component 14, which facilitates quick replacement of the lower mold of different cavities and is suitable for various specifications of keel; the die-cutting blade 6 is constrained by the limiting component 4 to avoid skeletal cutting; the electric telescopic rod 502 provides stable thrust; the ball bearing 1002 converts the adjustment friction into rolling friction, which is labor-saving and reliable in clamping. The whole machine has a compact structure, high positioning accuracy, high cutting efficiency, modular design and convenient maintenance. The key stress-bearing components are made of high-strength materials and heat-treated, which is suitable for batch and standardized cutting processing of keel components of prefabricated buildings.

[0044] It is worth noting that: the input end of the electric telescopic rod 502 is electrically connected to the output end of the external controller to ensure that the external controller controls the extension and retraction of the electric telescopic rod 502. The electric telescopic rod 502 can use a DC 24V push rod motor with a rated thrust of not less than 3000N, a stroke of 100mm, and a running speed of 30mm / s. It has a built-in upper limit switch to prevent overtravel. The electric telescopic rod 502 can be replaced with a pneumatic telescopic rod or a hydraulic telescopic rod. The six cutting edges of the die-cutting knife should be coated with a small amount of grease every 5000 processing cycles to prevent chip adhesion. The equipment should be reliably grounded before use to ensure safe operation.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
