Description

Technical Field

[0001] The present application relates to the field of steel section processing devices, and in particular to a cutting machine. Background Art

[0002] When processing steel sections, a cutting machine is usually used to cut the processed steel sections into required lengths. A common cutting machine includes a conveyor roller and a cutting machine body arranged above the conveyor roller. The steel sections are placed on the conveyor roller, and the conveyor roller conveys the steel sections to the cutting machine body for cutting. After cutting a section, the conveyor roller continues to convey the steel sections, so that the cutting machine body cuts the steel sections again.

[0003] Since a steel section needs to be cut continuously when cutting the steel section, a common fixing device needs to be disassembled and re-fixed each time cutting is performed, which makes the steps of cutting the steel section cumbersome. Summary of the invention

[0004] In order to reduce the steps of cutting steel sections, the present application provides a cutting machine.

[0005] The present application provides a cutting machine adopting the following technical solution: A cutting machine comprises a conveying roller and a cutting machine body arranged on the conveying roller, wherein two side plates are fixedly connected to the frame of the conveying roller, the roller body of the conveying roller is located between the two side plates, and the side plate is located at one side of the feed inlet of the cutting machine body, and two clamping plates are arranged between the two side plates; At least two connecting rods are connected to the side walls of the two clamping plates that are away from each other. The connecting rods penetrate the corresponding side plates and are slidably plugged into the side plates. A connecting spring is provided between the clamping plate and the corresponding side plate. One end of the connecting spring is fixed to the clamping plate, and the other end of the connecting spring is fixed to the side plate. The conveying roller is also provided with a control component for controlling the two clamping plates to move along the width direction of the conveying roller.

[0006] By adopting the above technical scheme, in the initial state, the connecting spring limits the clamping plate so that the distance between the two clamping plates is smaller than the width of the steel section. When the steel section needs to be fixed, the operator uses the control component to move the two clamping plates away from each other, and the clamping plates drive the connecting rod to move. At the same time, the clamping plates and the side plates cooperate to compress the connecting spring until the distance between the two clamping plates can allow the crossbeam to pass; then the two clamping plates are kept in the position at this time, and the steel section is moved between the two clamping plates, and then the two clamping plates are moved towards each other through the control component until the clamping plates contact the steel section. In the process of cutting the steel section, the two clamping plates cooperate to limit the steel section, thereby reducing the occurrence of tilting of the steel section cut. When the cutting is completed, the steel section is moved so that the steel section and the clamping plates move relative to each other. At the same time, the clamping plates can also limit the steel section, thereby reducing the need for repeated disassembly and re-fixing of the steel section during continuous cutting, thereby reducing the steps of cutting the steel section.

[0007] Optionally, the control component includes a cross beam, which is arranged above the two side plates, and the length direction of the cross beam is arranged along the width direction of the conveyor roller. Support rods are connected to both sides of the lower surface of the cross beam, and the support rods are slidably connected to the corresponding side plates, and the support rods slide in the vertical direction. The cross beam is hinged with hinged rods corresponding to the clamping plates one by one, and the end of the hinged rod away from the cross beam is hinged to the corresponding clamping plate, and the ends of the two hinged rods close to the cross beam are inclined in a direction approaching each other. The control component also includes a driving component for supporting the cross beam and driving the cross beam to move.

[0008] By adopting the above technical solution, in the initial state, the driving member supports the crossbeam. When it is necessary to fix the steel section, the driving member is controlled to work to move the crossbeam downward. The movement of the crossbeam drives the hinged rod to rotate, so that the lower ends of the two hinged rods rotate in the direction away from each other. The hinged rod pushes the corresponding clamping plate to move, thereby moving the two clamping plates away from each other. When the distance between the two clamping plates is large enough for the steel section to pass through, the driving member is controlled to keep the crossbeam, the hinged rod and the clamping plate in the current state.

[0009] When the steel section enters the two clamps, the driving part is controlled to work, causing the crossbeam to move upward. The movement of the crossbeam drives the hinge rod to rotate. At the same time, the connecting spring recovers its deformation and pushes the clamps to move, causing the two clamps to move toward each other until the clamps contact the steel section.

[0010] Optionally, a slider is connected to the support rod, and a slide groove adapted to the slider is provided on the side panel, the length direction of the slide groove is arranged along the height direction of the conveyor roller, and the slider is slidably inserted in the slide groove.

[0011] By adopting the above technical solution, the sliding block cooperates with the sliding groove so that the support rod is slidably connected with the side plate.

[0012] Optionally, the driving member includes a handle fixedly connected to both side walls of the beam, a connecting spring is connected to the slider, and an end of the connecting spring away from the slider is fixedly connected to the slot wall at the corresponding end of the sliding slot.

[0013] By adopting the above technical solution, the connecting spring supports the slider, the support rod and the cross beam. When the two splints need to be moved away from each other, the handle is pulled downward, and the handle drives the cross beam, the support rod and the slider to move downward, and the slider compresses the supporting spring; when the two splints need to be moved toward each other, the handle is released, the supporting spring restores its deformation and pushes the slider, the support rod and the cross beam to move upward, so that the cross beam releases the limitation on the hinge rod, and at the same time the connecting spring can also restore its deformation, and the connecting spring restores its deformation and pushes the splint to move, so that the two splints can move toward each other.

[0014] Optionally, convex plates are fixedly connected to two opposite side walls of the crossbeam, a motor is provided under one of the convex plates, the motor is mounted on the frame of the conveyor roller, the output shaft of the motor is arranged upward, a lead screw is fixedly connected to the output shaft of the motor, a convex plate is fixedly connected to the crossbeam, the lead screw passes through the convex plate and cooperates with the thread of the convex plate; A guide rod is penetrated and slidably inserted on the other convex plate, and the lower end of the guide rod is fixed to the frame body of the conveying roller.

[0015] By adopting the above technical scheme, when it is necessary to move the two splints in the direction away from each other, the motor is controlled to work, so that the motor drives the lead screw to rotate, and the lead screw cooperates with the guide rod to drive the crossbeam to move downward. The movement of the crossbeam causes the hinged rod to rotate, and the lower ends of the two hinged rods move in the direction away from each other. The hinged rod rotates and pushes the corresponding splints to move, thereby causing the two splints to move in the direction away from each other; when it is necessary to move the two splints in the direction close to each other, the output shaft of the control motor is rotated in the opposite direction, and the crossbeam moves upward, so that the crossbeam releases the limit on the hinged rod, and at the same time the connecting spring can also restore the deformation. The connecting spring restores the deformation and pushes the splint to move, thereby causing the two splints to move in the direction close to each other.

[0016] Optionally, one end of the connecting rod away from the clamping plate is fixedly connected to an anti-slip plate.

[0017] By adopting the above technical solution, the situation of the connecting rod being separated from the side plate is reduced, so that both the connecting rod and the clamping plate can better cooperate with the side plate.

[0018] Optionally, the surfaces of the two clamping plates close to each other are rotatably connected with a plurality of balls.

[0019] By adopting the above technical solution, the balls and the steel sections are rolled together, making the steel sections move more smoothly.

[0020] Optionally, the connecting spring is sleeved on the connecting rod.

[0021] By adopting the above technical solution, the connecting rod supports the connecting spring, thereby reducing the occurrence of bending of the connecting spring.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: By providing the clamping plate, connecting rod, connecting spring, side plate and control assembly, the need to repeatedly dismantle and re-fix the steel section during continuous cutting is reduced, thereby reducing the steps of cutting the steel section; By arranging the crossbeam, the hinge rod, the support rod and the driving member, the movement of the two clamping plates can be controlled; By arranging a handle and a supporting spring, the crossbeam can be driven to move in a vertical direction.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-5 This application is described in further detail.

[0030] The embodiment of the present application discloses a cutting machine. Example

[0032] Reference Figure 2 and Figure 3 Two clamping plates 4 are arranged between the two side plates 3, the clamping plates 4 and the side plates 3 are parallel to each other, and at least two connecting rods 5 are fixedly connected to the side walls of the two clamping plates 4 that are away from each other, and the connecting rods 5 are arranged horizontally; in this embodiment, the number of connecting rods 5 on each clamping plate 4 is two, and the two connecting rods 5 are arranged along the length direction of the conveyor roller 1, and the connecting rods 5 pass through the corresponding side plates 3 and are slidably plugged with the side plates 3.

[0033] The end of the connecting rod 5 away from the splint 4 is fixedly connected with an anti-slip plate 6, which reduces the possibility of the connecting rod 5 moving away from the side plate 3, making the cooperation between the connecting rod 5 and the splint 4 and the side plate 3 more stable; a plurality of balls 41 are rotatably connected on the side walls of the two splints 4 that are close to each other, and the balls 41 reduce the contact area between the splint 4 and the steel section, thereby making the steel section move more smoothly.

[0034] Reference Figure 2 and Figure 3 The conveyor roller 1 is also provided with a control component 8 for controlling the clamping plate 4 to move along the width direction of the conveyor roller 1. The control component 8 includes a crossbeam 81. The length direction of the crossbeam 81 is arranged along the width direction of the conveyor roller 1. The crossbeam 81 is located above the two clamping plates 4; both ends of the lower surface of the crossbeam 81 are fixedly connected with vertically arranged support rods 82, and the two side plates 3 are located between the two support rods 82. The support rods 82 are fixedly connected with sliders 83 on the side walls close to the side plates 3. The side plates 3 are provided with slide grooves 31 corresponding to the sliders 83 one by one. The length direction of the slide grooves 31 is arranged along the height direction of the conveyor roller 1. The slider 83 is slidably inserted in the slide grooves 31. The slider 83 cooperates with the slide grooves 31 to enable the support rods 82 and the crossbeam 81 to slide in the vertical direction.

[0035] The lower surface of the cross beam 81 is hinged with a hinged rod 84 corresponding to the clamp plate 4 one by one, and the end of the hinged rod 84 away from the cross beam 81 is hinged with the corresponding clamp plate 4, and the ends of the two hinged rods 84 close to the cross beam 81 are inclined in a direction approaching each other; the control component 8 also includes a driving member 85 for driving the support rod 82 and the cross beam 81 to move in the vertical direction, and the driving member 85 includes a handle 851 fixedly connected to the two ends of the cross beam 81, and the lower surface of the slider 83 is fixedly connected with a support spring 852, and the lower end of the support spring 852 is fixed to the lower end groove wall of the slide groove 31, and the limit spring supports the slider 83, the support rod 82 and the cross beam 81.

[0036] In the initial state, the support spring 852 supports the support rod 82 and the cross beam 81, and the connecting spring 7 cooperates with the side plate 3 to limit the clamping plate 4, so that the distance between the two clamping plates 4 is smaller than the width of the steel section; when the steel section needs to be limited, the operator pulls the handle 851 downward, and the handle 851 drives the cross beam 81, the support rod 82 and the slider 83 to move downward, and the slider 83 moves to compress the support spring 852; the downward movement of the cross beam 81 drives the upper end of the hinged rod 84 to move downward, so that the lower ends of the two hinged rods 84 rotate in a direction away from each other, thereby causing the hinged rod 84 to drive the corresponding clamping plate 4 to move, that is, the two clamping plates 4 move in a direction away from each other.

[0037] The splint 4 drives the connecting rod 5 and the anti-slip plate 6 to move, and as the distance between the splint 4 and the side plate 3 gradually decreases, the connecting spring 7 is compressed; when the gap between the two splints 4 is greater than the width of the steel section, the steel section is moved between the two splints 4, and then the handle 851 is released, the supporting spring 852 and the connecting spring 7 both restore their deformation, and the supporting spring 852 pushes the slider 83, the support rod 82 and the cross beam 81 to move upward, and the movement of the cross beam 81 drives the corresponding end of the hinge rod 84 to rotate; the connecting spring 7 pushes the splint 4 to move until the ball 41 is pressed against the steel section, and the two splints 4 and the connecting spring 7 cooperate to limit the steel section. After the cutting is completed, the steel section can be pushed to continue moving, which reduces the need to disassemble and re-fix the steel section each time cutting is performed, thereby reducing the steps of cutting the steel section.

[0038] The implementation principle of Example 1 of the present application is as follows: the operator presses the handle 851 downward, and the handle 851 drives the crossbeam 81 and the support rod 82 to move downward, and compresses the support spring 852; the movement of the crossbeam 81 drives the hinged rod 84 to rotate, and the hinged rod 84 pushes the clamping plate 4 to move, so that the two clamping plates 4 move away from each other until the distance between the two clamping plates 4 is large enough for the steel section to pass; the operator moves the steel section between the two clamping plates 4, and then releases the handle 851, and the support spring 852 and the connecting spring 7 both restore their deformation, so that the crossbeam 81 moves upward, and the movement of the crossbeam 81 drives the hinged rod 84 to rotate, and the connecting spring 7 moves the clamping plate 4 until the ball 41 contacts the steel section. Example

[0039] Reference Figure 4 and Figure 5The difference between this embodiment and embodiment 1 lies in the driving member 85.

A support plate 857 is fixedly connected to the frame of the conveyor roller 1, and the lower end of the guide rod 856 is fixedly connected to the support plate 857.

[0040] The implementation principle of Example 2 of the present application is as follows: when it is necessary to fix the steel section, the operator controls the motor 854 to work, the output shaft of the motor 854 rotates to drive the screw 855 to rotate, the screw 855 cooperates with the guide rod 856 to move the beam 81 downward, and the beam 81 drives the two clamps 4 to move through the two hinged rods 84, so that the two clamps 4 move away from each other, and the movement of the clamps 4 compresses the connecting spring 7 until the steel section can pass between the two clamps 4; insert the steel section between the two clamps 4, control the motor 854 to work, so that the output shaft of the motor 854 rotates in the opposite direction, the beam 81 moves upward, and at the same time the connecting spring 7 recovers its deformation and drives the clamps 4 to move until the balls 41 on the two clamps 4 are in contact with the steel section, and then turn off the motor 854.
