Specific embodiments

[0020] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model. On the contrary, the embodiments of the present utility model include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0021] The column processing sawing machine according to the embodiment of the present utility model will be described below with reference to the drawings.

[0022] As Figures 1 to 4 shown, the column processing sawing machine according to the embodiment of the present utility model may include a conveyor table 1, a support frame 2, a support table 3, a sawing mechanism 4, two limiting components 5 and a blank discharging component 6.

[0023] Among them, a first groove 10 is provided on the upper surface of the conveyor table 1, and a plurality of conveyor rollers 11 are rotatably connected inside the first groove 10. The support frame 2 is arranged between the conveyor table 1 and the support table 3; a hydraulic cylinder 12 is provided on the support frame 2, and the sawing mechanism 4 is arranged at the output end of the hydraulic cylinder 12.

[0024] It should be noted that the sawing mechanism 4 described in this embodiment includes a saw band, saw band wheels, guide wheels and a feeding device. Among them, the function of the saw band wheels is to control the movement of the saw band, the function of the guide wheels is to control the running direction of the saw band, and the feeding device is to control the feeding speed of the saw band. It can be understood that the specific structure of the sawing mechanism 4 is common knowledge in the art, and will not be elaborated in detail in the present utility model.

[0025] Further, the conveying roller 11 is flush with the upper surface of the conveying table 1. The support frame 2 is a U-shaped bracket. The sawing mechanism 4 is slidably connected to the support frame 2, and the hydraulic cylinder 12 can drive the sawing mechanism 4 to move up and down, so as to cut the column.

[0026] A second groove 7 is provided on the upper surface of the conveying table 1. A ball screw 8 is rotatably connected in the second groove 7. Two nut sliders 9 are provided on the ball screw 8, and the nut sliders 9 are slidably connected to the second groove 7. An installation plate 13 is provided on one side of the support frame 2. Two limiting components 5 are respectively arranged on the corresponding nut sliders 9, and the limiting components 5 are connected to the installation plate 13. The blanking component 6 is arranged on the support table 3, and the blanking component 6 is connected to the ball screw 8 through a transmission component 14.

[0027] It should be noted that two types of threads with opposite directions are provided on the ball screw 8 in this embodiment. The two nut sliders 9 are respectively arranged on different threads, and the ball screw 8 is connected to a motor. The motor can drive the ball screw 8 to rotate, so as to drive the two nut sliders 9 to move towards or away from each other.

[0028] Further, the limiting component 5 can stably limit the movement of the column in four directions on both sides and up and down at the same time, effectively preventing any deviation phenomenon during the cutting process, and ensuring that the operation is both safe and convenient.

[0029] In an embodiment of the present invention, as Figure 2 shown, the limiting component 5 includes a vertical plate 50, a horizontal plate 51, a sliding rod 52, a spring 53 and a pressing plate 54. Among them, the vertical plate 50 is installed on the upper surface of the nut slider 9. First sliding grooves 500 are respectively provided on the opposite surfaces of the two vertical plates 50, and the horizontal plate 51 is slidably connected to the first sliding grooves 500. Two second sliding grooves 130 are symmetrically provided on the installation plate 13. One end of the sliding rod 52 is connected to the horizontal plate 51, and the other end of the sliding rod 52 is slidably connected to the second sliding grooves 130. The spring 53 is arranged on the lower surface of the horizontal plate 51. The pressing plate 54 is arranged at the end of the spring 53.

[0030] It should be noted that the second sliding grooves 130 are inclined downward towards the middle of the installation plate 13. When the ball screw 8 rotates, with the cooperation of the nut slider 9, the two vertical plates 50 are driven to approach each other, so as to limit the left and right sides of the column. At the same time, with the cooperation of the first sliding grooves 500 and the sliding rod 52, the horizontal plate 51 moves downward, so as to drive the pressing plate 54 to move downward. When the pressing plate 54 contacts the column, the column can be pressed to achieve the up and down limit of the column.

[0031] Further, in order to reduce the friction between the pressing plate 54 and the column, a plurality of freely rolling balls can be arranged at the bottom of the pressing plate 54. The rolling friction between the balls and the column is small, which is more convenient to move the pressing plate 54.

[0032] In one embodiment of the present invention, Figure 3 As shown, the blanking assembly 6 includes a rotating shaft 60 and a blanking plate 61, wherein the upper surface of the support platform 3 is provided with a receiving groove 30, the rotating shaft 60 is rotatably connected to the receiving groove 30, and one end of the rotating shaft 60 extends to the outside of the receiving groove 30; the blanking plate 61 is arranged on the rotating shaft 60.

[0033] It should be noted that the rotating shaft 60 is arranged near the sawing mechanism 4. By driving the rotating shaft 60 to rotate, the blanking plate 61 can be driven to tilt, thereby facilitating blanking.

[0034] Furthermore, if Figure 3 As shown, a discharge port 31 is provided on the receiving groove 30 , and a guide plate 15 is obliquely provided on the discharge port 31 .

[0035] It should be noted that the guide plate 15 extends to the outside of the receiving groove 30 , and the sawed column can be guided to the outside of the receiving groove 30 through the guide plate 15 .

[0036] In one embodiment of the present invention, the transmission assembly 14 includes two gears 140 and a toothed chain 141 , wherein the two gears 140 are respectively disposed on the ball screw 8 and the rotating shaft 60 , and the two gears 140 are connected to each other through the toothed chain 141 .

[0037] In the embodiment of the present utility model, when the ball screw 8 rotates, the gear 140 and the toothed chain 141 cooperate to drive the rotating shaft 60 to rotate and drive the blanking plate 61 to tilt.

[0038] Specifically, during the sawing process of the column, the column is transported to the bottom of the sawing mechanism 4 by the conveying roller 11, and then the relevant personnel control the ball screw 8 to rotate in the first direction. The ball screw 8 drives the two nut sliders 9 to move closer to each other. At the same time, with the cooperation of the slide rod 52 and the first slide groove 500, the two horizontal plates 51 move downward. When the two vertical plates 50 contact the two sides of the column respectively, the pressing plate 54 contacts the upper part of the column, and the spring 53 is compressed, thereby realizing the simultaneous limitation of the up and down and left and right directions of the column. The operation is convenient and can effectively prevent the column from shifting.

[0039] Then the relevant personnel can control the sawing mechanism 4 to start, so as to drive the saw belt to move horizontally, and drive the sawing mechanism 4 to move slowly downward through the hydraulic cylinder 12, thereby realizing the sawing process of the column.

[0040] After the sawing is completed, the relevant personnel control the sawing mechanism 4 to move upward above the column, and control the ball screw 8 to rotate in the second direction to drive the two limiting components 5 to move in the reverse direction, thereby releasing the limiting force on the column. At the same time, under the cooperation of the gear 140 and the tooth chain 141, the rotating shaft 60 can be driven to rotate, and the rotating shaft 60 drives the blanking plate 61 to rotate downward by a certain angle. At this time, the sawn column will slide down along the inclined blanking plate 61 to the guide plate 15, realizing the blanking process of the column.

[0041] In summary, the column processing sawing machine of the embodiment of the present utility model can simultaneously realize the limiting of the column in the left, right, up, and down four directions, greatly simplifies the limiting operation steps, and integrates the functions of support and blanking, effectively avoiding the instability of the column in the later stage of cutting, and significantly improving the sawing efficiency and processing quality of the column.
