Description

Technical Field

[0001] The invention relates to the technical field of round steel production, in particular to the technical field of a round steel cutting machine. Background Art

[0002] Round steel is a widely used type of steel in the market. It is suitable for various fields of design and mechanical processing, including industrial production, aerospace, construction materials and marine engineering. Round steel plays a counterweight and support role in marine engineering. It is welded with wire rod to form a protective net. It is an important building material for marine engineering. At the same time, round steel needs to be cut by a cutting machine during use to meet the needs of different engineering projects and improve work efficiency.

[0003] When cutting, the existing round steel cutting machine requires the staff to measure the length of the round steel to be cut with a ruler in advance, and then adjust the push rod used to abut the end of the round steel so that the distance from the push rod to the cutting knife is the length to be cut. Every time the round steel of different lengths needs to be cut, the staff is required to measure manually, which increases the labor intensity of the staff.

[0004] In order to solve the problems raised in the above-mentioned technology, for example, application number CN201922112349.5 discloses a round steel cutting machine, including a frame, a feeding channel for round steel to enter is opened on one side of the frame, a cutting knife for cutting the round steel is arranged in the frame, and a feeding mechanism is arranged at one end of the frame away from the feeding channel, and the feeding mechanism includes a positioning frame arranged on the frame, and a push rod for limiting the end of the round steel is arranged at the bottom of the positioning frame. Through the scale at the top of the positioning frame, the position of the push rod is sleeved with two indicator needles extending to the top of the positioning frame and capable of indicating the scale, the push rod is driven to move, and the indicator needle is driven to slide on the scale at the same time, and the distance value from the indicator needle to the cutting knife can be clearly read from the indicator needle, that is, the distance from the push rod to the cutting knife can be accurately adjusted, instead of the traditional manual use of a ruler to measure and adjust the distance from the push rod to the cutting knife, reducing the labor intensity of the staff, but the device still has the following defects: During the cutting process of the device, the cutting stress of the round steel causes the round steel to jump along the cutting direction, resulting in the round steel being unable to fit tightly with the inner cavity of the locking clamp, thereby making the cut surface of the produced round steel uneven.

[0005] In order to solve the problems raised in the above-mentioned technology, for example, application number CN202021771228.8 discloses a round steel cutting machine, including a machine base, a cutting mechanism and a feeding mechanism are arranged on the machine base, a fixed seat is arranged between the cutting mechanism and the feeding mechanism, a discharge port is opened on the side wall of the fixed seat facing the cutting mechanism, the cutting mechanism includes a cutting bracket, a first hydraulic cylinder is horizontally arranged on the cutting bracket, a telescopic rod is connected in the first hydraulic cylinder, and a cutting table is fixedly connected to the end of the telescopic rod away from the first hydraulic cylinder. In the process of cutting the round steel, the top column limits the degree of freedom of the round steel in the axial direction, and the clamping rod and the cutting groove limit the degree of freedom of the round steel along the moving direction of the cutting table, so that the round steel will not jump slightly when being cut, thereby ensuring the flatness of the cut surface of the round steel, but the device still has the following defects: This device may have certain limitations when it is necessary to accurately clamp round steel bars of different diameters or materials, so different clamping tools need to be replaced, resulting in complicated operations and low processing efficiency.

DETAILED DESCRIPTION

[0017] See also Figures 1 to 5The present invention provides a round steel cutting machine, comprising a concave support 1, a clamping mechanism 2, a transverse slide rail 21, a transverse slider 22, a support plate 23, a clamping plate 24, a rack 25, a rotating mechanism 3, a cutting table 4, a cutting mechanism 5 and an auxiliary roller mechanism 6.

There are two transverse slide rails 21 and they are symmetrically arranged in parallel. Two transverse sliders 22 are slidably arranged on the two transverse slide rails 21. A support plate 23 is commonly connected between each two transverse sliders 22. A clamping plate 24 is arranged at the middle part above the two support plates 23. The clamping plates 24 are symmetrically arranged. The side walls of the support plate 23 are provided with racks 25, and the racks 25 are symmetrically arranged. A rotating mechanism 3 is rotatably arranged above the concave support 1 and between the two racks 25. A cutting table 4 is arranged in the middle above the concave support 1, and a cutting mechanism 5 is arranged above the cutting table 4. An auxiliary roller mechanism 6 is arranged above the concave support 1 and between the clamping mechanism 2 and the cutting mechanism 5. The two racks 25 are driven to move relative to each other through the rotation of the gear 33, and then the transverse slider 22 under the support plate 23 is driven to slide on the transverse slide rail 21, thereby driving the two clamping plates 24 to move closer to or away from each other, and the spacing between the clamping plates 24 can be adjusted, so as to clamp and fix round steels of different diameters, making the processing and cutting process more flexible and diverse.

[0018] See also Figure 5 The clamping plates 24 are all V-shaped structures. By setting the clamping plates 24 to be V-shaped structures, the clamping plates 24 can fit more closely to the outer wall of the round steel, thereby increasing the clamping and fixing effect.

[0019] See also Figure 2 The rotating mechanism 3 includes a motor 31, an output shaft 32 and a gear 33. The motor 31 is installed below the concave support 1 by bolts. The output shaft 32 is rotatably set on the concave support 1. The output end of the motor 31 passes through the concave support 1 and is connected to the output shaft 32. The top of the output shaft 32 is rotatably set with a gear 33. The gear 33 is meshed and connected with the two racks 25. The motor 31 is started through the control panel 7, and the motor 31 drives the output shaft 32 to rotate forward and reverse, thereby driving the gear 33 to rotate forward and reverse, thereby driving the two racks 25 to move relative to each other.

[0020] See also Figure 1 A control panel 7 is installed on the side wall of the concave support 1, and the output end of the control panel 7 is connected to the input end of the motor 31, and the input end of the control panel 7 is electrically connected to an external power supply.

[0021] See also Figure 3 The cutting mechanism 5 includes a concave bracket 51, a cylinder 52, a hydraulic rod 53, a cutting knife 54, a vertical slide rail 55, a vertical slider 56 and an L-shaped support rod 57. The cylinder 52 is installed in the upper middle part of the concave bracket 51 by bolts. The output end of the cylinder 52 passes through the bottom of the concave bracket 51 and is connected to the hydraulic rod 53. The lower end of the hydraulic rod 53 is connected to the cutting knife 54. The cutting knife 54 corresponds to the upper and lower positions of the cutting table 4. The inner side wall of the concave bracket 51 is symmetrically provided with vertical slide rails 55. Vertical sliders 56 are slidably provided on the two vertical slide rails 55, and the side walls of the vertical sliders 56 are provided with L-shaped support rods 57. The lower ends of the L-shaped support rods 57 are connected to the top of the cutting knife 54, and the input end of the cylinder 52 is electrically connected to the output end of the control panel 7. The hydraulic rod 53 is driven to descend by the cylinder 52, thereby driving the cutting knife 54 to descend. During the descent of the cutting knife 54, the vertical sliders 56 on both sides are driven to slide on the vertical slide rails 55, thereby cutting the round steel, thereby ensuring the processing quality.

[0022] See also Figure 4 The auxiliary roller mechanism 6 includes a groove 61, a fixing frame 62, a rotating groove 63 and a roller 64. The groove 61 is opened on the concave support 1, and a fixing frame 62 is arranged inside the groove 61. The fixing frame 62 is provided with a rotating groove 63. The inside of the rotating groove 63 is rotatably connected with a roller 64 through a pin shaft. The roller 64 is parallel to the top of the cutting table 4. After the round steel is cut for a section, the staff continues to push the round steel forward, so that the roller 64 on the concave support 1 rolls, thereby driving the round steel to move forward, so that the staff can save time and effort in the process of pushing, and the operation is more convenient.

[0023] See also Figure 1 A feeding chute 8 is provided on one side above the concave support 1, and the feeding chute 8 is tilted downward so that the cut round steel can fall into the feeding chute 8 and slide through the feeding chute 8 to be collected in the receiving box 9.

By setting the material receiving box 9, the cut round steel can be collected uniformly, which is convenient for subsequent processing.

[0025] Working process of the present invention: During the operation of the round steel cutting machine of the present invention, the staff first puts the round steel between the upper surface of the roller 64 and the two clamping plates 24, and then starts the motor 31 through the control panel 7. The motor 31 drives the output shaft 32 to rotate, thereby driving the gear 33 to rotate, thereby driving the two racks 25 to move relative to each other. At the same time, the transverse slider 22 under the support plate 23 slides on the transverse slide rail 21, thereby driving the two clamping plates 24 to approach the outer wall of the round steel until they contact the outer surface of the round steel, ensuring the stable clamping and fixing of the round steel. After the round steel is clamped and fixed, the hydraulic rod 53 is driven to descend by the cylinder 52, thereby driving the cutting knife 54 to descend, and the cutting knife 54 descends. During the lowering process, the vertical sliders 56 on both sides are driven to slide on the vertical slide rails 55, thereby cutting the round steel, so that the cut round steel can fall into the discharge chute 8 and slide through the discharge chute 8 to the receiving box 9 for collection. At the same time, after the round steel is cut for a section, the staff continues to push the round steel forward, so that the roller 64 on the concave support 1 rolls, thereby driving the round steel to move forward, so that the staff can save time and effort in the pushing process, and provide more flexibility and precision for the processing operation, so that the clamping force can be adjusted according to round steels of different diameters, making the processing and cutting process more flexible and diverse, and there is no need to replace the fixture or adjust the equipment, and the adaptability is stronger.

[0026] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and wiring layout in detail.
