DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 6As shown, a side cutting device for a concrete self-insulating block comprises a main frame 1, columns 2 are arranged on both sides of the main frame 1, a pre-cutting device 3 and a side cutting device 4 are sequentially arranged in the main frame 1 along the feeding direction of the pieces to be cut, the pre-cutting device 3 comprises a milling cutter frame 5 arranged on the two sides of the main frame 1 in the longitudinal direction perpendicular to the feeding direction, the milling cutter frame 5 is longitudinally connected with a plurality of milling cutter clamps 6, the milling cutter clamps 6 are installed with a milling cutter head 7, the milling cutter head 7 can be an angle milling cutter and / or a saw blade milling cutter for opening pointed grooves; the side cutting device 4 comprises a wire mounting frame, the wire mounting frame comprises a longitudinal connecting column 8, at least the upper end and the lower end of the longitudinal connecting column 8 are connected to the column 2 through a sliding module 9, and a group of driving cylinders 10 are respectively arranged at both ends of each group of wire mounting frames, and the driving cylinder 10 connects the longitudinal connecting column 8 and the column 2. The longitudinal connecting column 8 is connected to the transverse connecting column 11, and the transverse connecting column 11 is connected to the longitudinal mounting plate 12. Cutting wires 13 are longitudinally mounted at both ends of the wire mounting frame, and wire clamps 14 are longitudinally arranged and connected on the longitudinal mounting plate 12. A wire clamping hole 15 is longitudinally arranged at the head of the wire clamp 14, and the cutting wire 13 is passed through the wire clamping hole 15 for clamping the cutting wire 13 in sections. The longitudinal position height of the wire clamp 14 is consistent with that of the milling cutter head 7, so that the wire clamp 14 passes along the groove milled by the milling cutter head 7. First, use a milling cutter to wash out the groove, and then use the segmented clamped steel wire to perform side cutting. The steel wire is clamped in segments to reduce the unstable guidance when cutting long steel wires, which has a greater impact on ductility, easy deviation of the guidance, and uneven force in the length direction, which has inconsistent effects on the ductility of the steel wire. Therefore, the side cutting of the blank is prone to unevenness, and the uncertain pores and obstructive particles have a greater impact. The steel wire is easy to break and the blank section accuracy is low.

[0024] The beneficial effects of this embodiment are as follows: by setting up a pre-cutting device in advance, the billet is pre-divided into multiple sections from top to bottom on the side, the whole side of the billet is divided into sections, and then the corresponding number of side cutting wire segments are set in the sections to perform zoned wire cutting on the above sections, the side cutting billets of each section are evenly stressed, the wire cutting of a smaller area avoids knife clamping, the scum in the gap is discharged in time, the semi-finished billet is evenly stressed, the deformation is reduced, and the billet cutting effect is better

[0025] In other specific embodiments, Figure 5 and 6As shown, the wire clamp 14 includes a first clamp half 1401 and a second clamp half 1402, and the heads of the first clamp half 1401 and the second clamp half 1402 are each provided with a half hole. The longitudinal mounting plate 12 includes two mounting plates correspondingly mounted and connected to the first clamp half and the second clamp half, respectively. When the two mounting plates are positioned and installed, the first clamp half 1401 and the second clamp half 1402 are fixed together perpendicular to the direction of cutting the wire, and the two half holes are surrounded to form the wire clamping hole 15. The first clamp half 1401 and the second clamp half 1402 are each provided with a connecting ear 1403, and the connecting ear 1403 is provided with a connecting bolt to cooperate with the longitudinal mounting plate 12 to open and close the first clamp half 1401 and the second clamp half 1402. The wire clamping hole 15 is arranged in two halves, which is convenient for opening and closing clamping and replacing the wire. The opening and closing structure is perpendicular to the direction of the cutting wire. The design point is that it is a closed surface in the force direction of the wire cutting advancement, without an opening and closing seam, which is more conducive to segmenting the force on the cutting wire and more conducive to efficient cutting of the blank.

[0026] In other specific embodiments, the projection of the head of the wire clamp 14 in the XY plane is a flat shape 1404, and the projection in the XZ plane includes a tip 1405. The flat shape in the XY plane has higher strength, and has a higher tolerance to the force of the wire cut perpendicularly thereto, which is conducive to efficient cutting of the blank; the tip enables the wire clamp to move and cut along the milling cutter groove of the pre-cutting device, and the cutting depth of the wire is segmented and positioned, so that the depth consistency is more accurate, the side cutting accuracy is improved, the deformation caused by the ductility of the long wire is reduced, and the deformation coefficient is reduced.

[0027] In other specific embodiments, Figure 6 As shown, a hollow sleeve 17 is arranged in the steel wire clamping hole 15, the cutting steel wire 13 is passed through the hollow sleeve 17, lubricating oil 18 is injected between the hollow sleeve 17 and the steel wire clamping hole 15, and end caps 18 are arranged at the upper and lower ends of the hollow sleeve 17, and the diameter of the end cap 18 is larger than the diameter of the steel wire clamping hole 15. The hollow sleeve 17 is arranged in the steel wire clamping hole 15, so that the hollow sleeve 17 can slide relative to the steel wire clamping hole 15, which protects the steel wire, reduces the relative friction of the steel wire, and improves the service life of the steel wire; the lubricating oil also plays a role in heat conduction.

[0028] In other specific embodiments, Figure 6As shown, the hollow sleeve 17 is filled with a heat-conducting adhesive 16. The hollow sleeve 17 can slide relative to the steel wire clamping hole 15, and the steel wire is fixed relative to the sleeve by bonding, and does not move frictionally relative to the clamping hole. Then, the sleeve lubricates and adjusts the relative clamping hole by a small amount of movement, absorbs the elastic variation during steel wire cutting, reduces the relative friction damage of the steel wire, and reduces the breakage of the steel wire due to the absorption of the elastic variation, thereby improving the life of the cutting steel wire and the cutting efficiency of the overall equipment; in addition to the function of bonding and fixing the steel wire, the heat-conducting adhesive also has the function of heat conduction, that is, timely conduction of the heat generated by the cutting steel wire, thereby improving the life of the cutting steel wire.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
