Description

Technical Field

[0001] The utility model belongs to the technical field of construction machinery cutting equipment, in particular to a single-cylinder balanced cutting machine for construction engineering. Background Art

[0002] For the traditional cutting and processing of sheet non-metallic building materials such as foam materials, plastic materials, floor materials, glass fiber, cork, etc., most of them are cut by manual shearing. This manual cutting processing method is labor-intensive, low-efficiency, and high-cost. For this reason, the existing sheet non-metallic building material cutting and processing is also carried out by cutting machine equipment. The principle is to use the force of the movement of the equipment to pressurize the knife die to punch and cut the sheet non-metallic building materials.

[0003] Since sheet non-metallic building materials are relatively wide, the cutting machine model usually used for cutting is a balanced cutting machine. The existing low-cost balanced cutting machines generally use a single hydraulic cylinder to drive the die to punch under the limit of the guide structure to cut sheet non-metallic building materials. However, since the die of the balanced cutting machine is relatively wide, the shear force of the single cylinder acting on the middle position of the die is relatively large, and the shear force decreases as it moves away from the middle position of the die, resulting in inconsistent shear force, poor cutting stability and poor cutting quality. In addition, the position where the output end of the single cylinder is installed on the die is also difficult to reach the ideal middle position. As the single-cylinder balanced cutting machine works for a long time, the die is prone to poor parallelism, which causes the die to interfere with the guide structure used for its guidance, affecting processing efficiency.

[0004] Therefore, how to improve the disadvantages of inconsistent cutting force and poor parallelism of the knife die when the single-cylinder balanced cutting machine is working is a problem that needs to be solved urgently by technical personnel in this field. Utility Model Content

[0039] Example 1

[0040] like Figure 1 As shown, this embodiment provides a single-cylinder balanced cutting machine for construction engineering, which includes a base 10, a gantry 20, a power system 30, a cutting die 40 and a balancing system 50. Specifically, the gantry 20 is installed across the base 10; the power system 30 is installed at the top of the gantry 20, and its output end is arranged toward the base 10; the middle position of the cutting die 40 is installed at the output end of the power system 30.

[0041] like Figure 2As shown, the base 10 is provided with a cutting edge member corresponding to the cutting die 40, and the cutting edge member includes two cutting plates 11 arranged in parallel on the base, and the two cutting plates 11 are fixed to the base 10 through a knife seat. Furthermore, in order to form a cutting edge between the cutting die 40 and the cutting plate 11, the gap between the two cutting plates 11 is greater than the thickness of the cutting die 40, and the cutting of the material can be achieved by inserting the cutting die 40 between the two cutting plates 11. Preferably, the base 10 is provided with a leakage hole, and the leakage hole is arranged corresponding to the gap between the two cutting plates 11, and the waste after the material is cut falls into the waste bucket through the leakage hole.

[0042] like Figure 3 As shown, the single-cylinder balanced cutting machine also includes a balancing system 50, and the balancing system 50 includes two groups of connecting rod mechanisms 51, wherein the two connecting rod mechanisms 51 are symmetrically distributed with the output end of the power system 30 as the center. Each of the connecting rod mechanisms 51 includes a pair of mutually hinged first connecting rods 511 and second connecting rods 512, wherein the other end of the first connecting rod 511 is rotatably connected to the gantry, and the other end of the second connecting rod 512 is rotatably connected to the cutting die 40. Of course, the number of connecting rod mechanisms in other embodiments is not limited to two groups, and preferably an even number of connecting rod mechanisms are symmetrically distributed. In this embodiment, when the power system 30 drives the cutting die 40 downward, it drives the connecting rod mechanism 51 to move. At this time, the angle between the second pull rod 512 and the first pull rod 511 gradually increases, so that the connecting rod mechanism 51 generates a pre-tension on the entire cutting die 40, so that the entire cutting die 40 is in a relatively balanced state when it is downward; similarly, when the power system 30 drives the cutting die 40 upward, it drives the connecting rod mechanism 51 to move. At this time, the angle between the second pull rod 512 and the first pull rod 511 gradually decreases, so that the connecting rod mechanism 51 generates a pre-pressure on the entire cutting die 40, so that the entire cutting die 40 is in a relatively balanced state when it is upward, which can ensure that the cutting die 40 is in a relatively stable stress state during the upward and downward processes, thereby effectively improving the disadvantages of inconsistent cutting force and poor parallelism of the cutting die, and achieving the purpose of improving cutting stability, cutting quality and processing efficiency.

[0043] Furthermore, the cutting die 40 includes a cutting die seat 41 connected to the connecting rod mechanism 51 and a blade 42 provided on the cutting die seat 41. The second connecting rod 512 is rotatably mounted on the cutting die seat 41, and the edge end of the blade 42 is in a sawtooth structure. Since the material processed by the balanced cutting machine is a sheet of non-metallic building materials, the intermittent cracks are pre-pressed during cutting to prevent the occurrence of sticking of the knife, pulling of the mouth, etc., thereby improving the surface quality of the material cutting mouth.

[0044] Furthermore, the single-cylinder balanced cutting machine further includes a linkage rod 52, and the two ends of the linkage rod 52 are respectively connected to the hinge points of the two groups of the link mechanisms 51. Preferably, the connecting line of the hinge points of each of the link mechanisms 51 is arranged parallel to the cutting die 40, that is, during the upward and downward movement of the cutting die 40, the linkage rod 52 is always in a state parallel to the cutting die 40, further ensuring that the cutting die 40 is in a relatively stable stress state during the upward and downward movement.

[0045] Furthermore, each group of the connecting rod mechanism 51 is connected to the gantry through an adjusting member 22, wherein the first connecting rod 511 is rotatably connected to the gantry 20 through the adjusting member 22. Specifically, the adjusting member 22 has the function of linearly moving relative to the gantry along the direction perpendicular to the cutting die 40, so that each group of the connecting rod mechanism 51 can be adjusted along the direction perpendicular to the cutting die 40 through the adjusting member 22. In specific practice, due to installation errors or errors of the equipment itself, the initial cutting die 40 may be in a skewed state, so it can be adjusted through the adjusting member 22 to make it parallel to the horizontal direction.

[0046] like Figure 4 As shown, the die cutter seat 41 is connected to the output end of the power system 30 via a connecting plate 33. Preferably, the connecting plate 33 is in a triangular structure, one of which is connected to the output end of the power system 30, and the other two are connected to the T-block 32. By using the connecting plate 33 with a triangular structure to connect the T-block 32 and the die cutter seat 41, respectively, according to the principle of three points determining a plane, the stability of the die cutter 40 in the process of going up and down can be improved, and the cutting stability and cutting quality can be further improved.

[0047] Furthermore, the power system 30 includes a hydraulic cylinder 31 provided on the gantry and a T-block 32 provided at the output end of the hydraulic cylinder 31, and one end of the connecting plate 33 abuts against the T-block 32. Specifically, during the process of the blade 42 cutting the material, the top end of the connecting plate 33 abuts against the notch of the T-block 31, which can decompose the force of the fastener between the two and improve the service life of the connection between the two.

[0048] Combination Figures 1 to 4 As shown, the two columns of the gantry 20 are provided with a guide groove 21 arranged parallel to the cutting die 40, and the side ends of the cutting die 40 are placed in the corresponding guide groove 21, so that the cutting die 40 can move up and down along the guide groove 21. Because the connecting plate 33 is in a triangular structure, the stability of the cutting die 40 in the up and down movement can be ensured, and combined with the guiding function of the guide groove 21, the stability of the cutting die 40 in the up and down movement process can be effectively ensured, so as to achieve the purpose of cutting stability and cutting quality.

[0049] In summary, when the cutting die moves downward, the angle between the second pull rod and the first pull rod gradually increases, so that the connecting rod mechanism generates pre-tension on the entire cutting die, so that the entire cutting die is in a relatively balanced state when it moves downward; similarly, when the cutting die moves upward, the angle between the second pull rod and the first pull rod gradually decreases, so that the connecting rod mechanism generates pre-pressure on the entire cutting die, so that the entire cutting die is in a relatively balanced state when it moves upward, thereby ensuring that the cutting die is in a relatively stable stress state during the upward and downward processes, effectively improving the disadvantages of inconsistent cutting force and poor parallelism of the cutting die.

[0050] Example 2

[0051] like Figure 5 As shown, the difference between this embodiment and embodiment 1 is that each of the connecting rod mechanisms 51 includes two pairs of mutually hinged first connecting rods 511 and second connecting rods 512, and each pair of mutually hinged first connecting rods 511 and second connecting rods 512 are respectively located on both sides of the die holder 41 and are symmetrically distributed. In addition, the single-cylinder balanced cutting machine of this embodiment includes two connecting plates 33 and two linkage rods 52, which are respectively located on both sides of the die holder 40. This embodiment can further ensure that the die holder is in a relatively stable stress state during the upward and downward movement, and further improve the cutting stability and cutting quality.

[0052] Example 3

[0053] like Figure 6 As shown, the difference between this embodiment and embodiment 2 is that: the hinge points of the first connecting rod 511 and the second connecting rod 512 are equipped with torsion springs 513. When the cutting die moves up to the highest position, the torsion springs 513 are in a natural state, and when the cutting die moves down to the lowest position, the torsion springs 513 are in a state of maximum elasticity. Specifically, during the downward movement of the cutting die, the torsion springs 513 are in a stretched state, generating a pre-tension force on the cutting die; during the upward movement of the cutting die, the torsion springs 513 are in a pre-pressure state, thereby effectively ensuring that the cutting die is in a relatively stable stress state during the upward and downward movement.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
