Description

TECHNICAL FIELD

[0001] The utility model relates to laser pipe cutting machine equipment technical field more specifically, it is a kind of side-hung laser pipe cutting machine with semi-automatic feeding frame. BACKGROUND

[0002] Laser pipe cutting machine has been widely applied in industrial production, mainly for cutting pipe material of different shapes. In order to improve production efficiency, the supporting feeding frame has also been continuously optimized. The semi-automatic feeding frame on the market usually transports pipe material to pipe cutting machine for processing through conveying chain and block. However, due to the design limitation of traditional feeding frame, the following problems exist:

[0003] Limited capacity of the rack: the block spacing of the traditional feeding frame is large, which can only place a small number of pipe materials on the rack of the same length, usually 4-5. To increase the capacity, the length of the rack needs to be increased, which will occupy more equipment space and affect the factory layout.

[0004] Insufficient feeding accuracy: when the block cooperates with the lifting assembly, due to the low density of pipe material placement, the lifting assembly needs a certain length to adapt to pipe materials of different specifications, which may cause two pipe materials to be lifted at the same time, affecting the feeding stability and processing accuracy. INVENTION CONTENTS

[0005] Therefore, the utility model provides a side-hung laser pipe cutting machine with semi-automatic feeding frame.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A side-hung laser pipe cutting machine with semi-automatic feeding frame, comprising a pipe cutting machine for cutting pipe material and a feeding frame fixedly connected to the pipe cutting machine, the feeding frame is provided with a support connectable to the pipe cutting machine, the support is provided with a plurality of conveying assemblies, the side of the support close to the pipe cutting machine is provided with a plurality of chute assemblies, the pipe cutting machine is provided with a plurality of lifting assemblies corresponding in position to the chute assemblies, and the conveying assemblies can support and convey pipe material to the chute assemblies.

[0008] In the preferred technical scheme, the chute assembly comprises a feeding chute and at least one guide plate, the guide plate is provided with a downward inclined structure facing the feeding chute, and the feeding chute is provided with a blocking plate close to the pipe cutting machine.

[0009] In the preferred technical scheme, the feeding frame is provided with a driving motor capable of simultaneously driving a plurality of conveying assemblies, the plurality of conveying assemblies are connected with a driving rod, and the driving motor is connected with the driving rod and drives the conveying assemblies to move through the driving rod.

[0010] Preferably, the conveying assembly comprises at least two rotatable driving gears, one of which is connected with the driving rod; and a conveying chain, which is sleeved on the driving gears, and the pipe is placed on the conveying chain and moves to the direction of the pipe cutting machine under the driving of the driving gears.

[0011] Preferably, a plurality of stop blocks are arranged on the conveying chain at intervals, and the stop blocks protrude from the side of the conveying chain away from the driving gears.

[0012] Preferably, the support is provided with a plurality of supporting legs and a plurality of connecting legs for connecting the pipe cutting machine.

[0013] By arranging the chute assembly, the pipe can slide into the feeding groove under the action of the guide plate without relying on the precise positioning of the stop blocks. This design allows the distance between the stop blocks to be greatly reduced, allowing more stop blocks to be arranged on the conveying chain of the same length, significantly increasing the single feeding capacity. The length of the support can be reduced, saving space, while maintaining the efficiency and stability of the feeding rack. The chute assembly cooperates with the guide plate and the feeding groove to enable the pipe to slide into position, ensuring that the lifting assembly lifts one pipe at a time, avoiding the problem of multiple pipes being lifted at the same time in traditional structures, improving the stability and precision of the processing process. The width of the feeding rack is shortened, reducing the equipment footprint, and the cooperation of the chute assembly and the conveying assembly simplifies the feeding process, reduces the number of manual interventions, and improves the convenience of feeding operations. The pipe slides into the feeding groove by itself without the need for additional positioning procedures, the feeding time is shorter, and the feeding efficiency is improved.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] Please refer to a side-mounted laser tube cutting machine with a semi-automatic feeding rack. Figures 1-4 The system includes a pipe cutting machine 100 for cutting pipes and a loading rack 200 fixedly connected to the pipe cutting machine 100. The pipe cutting machine 100 is a cutting processing machine tool, specifically a side-mounted laser pipe cutting machine, the model and size of which are not limited, and it is usually used to cut pipes of different shapes. The loading rack 200 is connected to the machine bed of the pipe cutting machine 100 to ensure the stability of both during operation. The loading rack 200 is provided with a bracket 210 that can be connected to the pipe cutting machine 100. The bracket 210 serves as a support structure for the loading rack 200. The loading rack 200 is connected to the machine bed of the pipe cutting machine 100 through the bracket 210. Under normal circumstances, the loading rack 200 is connected to the side close to the pipe cutting machine 100, and the loading rack 200 transports the pipes to the pipe cutting machine 100 for cutting processing.

[0024] Furthermore, the support 210 is equipped with two conveying assemblies 220, such as... Figure 3 As shown, the support frame 210 has three structurally identical support frames, which are independent of each other. In other embodiments, the three support frames can be interconnected to form a single support frame 210. Two conveying components 220 are respectively provided on the left and right support frames, and a support beam is provided at a corresponding position on the middle support frame. In other embodiments, conveying components 220 can be provided on all three support frames. In this embodiment, two conveying components 220 are provided to convey the pipe, so one is omitted to reduce costs. During loading, the pipe is placed horizontally on the support frame 210. The two conveying components 220 and the support beam on the central support frame provide support for the pipe. The conveying components 220 provide power to convey the pipe towards the pipe cutting machine 100. The support frame 210 is provided with multiple chute assemblies 230 on the side near the pipe cutting machine 100, that is, each support frame is provided with a chute assembly 230; the pipe cutting machine 100 is provided with multiple lifting assemblies 110 corresponding to the positions of the chute assemblies 230; the conveying assembly 220 can support the pipe and convey the pipe to the chute assembly 230; the pipe will slide a certain distance after reaching the chute assembly 230 and then be in place; at this time, the lifting assembly 110 can lift the pipe to complete the feeding and processing.

[0025] Furthermore, the chute assembly 230 includes a feeding chute 231 and guide plates 232 on both sides. The guide plates 232 are provided with a downward inclined structure towards the feeding chute 231. The feeding chute 231 is provided with a baffle plate 233 on the side near the pipe cutter 100. The pipe is conveyed to the guide plate 232 by the conveying assembly 220. The downward inclined structure of the guide plate will cause the pipe to slide onto the feeding chute 231. The sliding distance of the pipe can be controlled by changing the length of the guide plate. The baffle plate 233 can block the pipe that slides into the feeding chute 231 and prevent the pipe from falling.

[0026] Furthermore, the loading rack 200 is equipped with a drive motor 240 capable of simultaneously driving multiple conveying components 220. Two conveying components are connected to drive rods 221. The drive motor 240 is connected to the drive rods 221 and drives the conveying components to move through the drive rods 221. The drive motor 240 is mounted on a support frame in the middle of the bracket 210. Since no conveying components 220 are mounted on the central support frame, the support frame is equipped with a rotating shaft structure connecting the drive rods 221 on both sides, so that the drive motor 240 can drive the conveying components 220 on both sides through the drive rods 221. The drive motor 240 is connected to the drive rods 221 through a gear structure to provide power to the drive rods 221. The conveying component 220 includes at least two rotatable drive gears 222, one of which is connected to the drive rod 221; a conveying chain 224 is sleeved on the two drive gears 222. The pipe is placed on the conveying chain 224 and moves towards the pipe cutter 100 by the drive of the drive gears 222. Drive gears 222 are located at the front and rear ends and connected by a rotating shaft structure on the bracket 210. After being connected to the drive rod 221, the drive gears 222 can be driven to rotate by the drive motor 240. The two drive gears 222 mounted on the conveyor chain 224 achieve cyclic sliding. The sliding direction and speed of the conveyor chain 224 are determined by the rotation direction of the drive motor 240. The pipe is placed on the conveyor chain 224 and moves as the conveyor chain 224 slides.

[0027] Furthermore, multiple stops 223 are spaced apart on the conveyor chain 224. The stops 223 protrude from the side of the conveyor chain 224 away from the drive gear 222, that is, the stops 223 protrude from the outer surface of the conveyor chain 224. When the conveyor chain 224 moves, it can be pushed by the stops 223 to ensure stable feeding. A tube is placed between every two stops 223, so that the bracket 210 can place multiple tubes at one time for processing. The tubes are conveyed to the chute assembly 230 at the same interval.

[0028] Furthermore, it should be noted that regarding the positional relationship between the chute assembly 230 and the lifting assembly 110, if the moving direction of the conveyor chain 224 is the X-axis, then the chute assembly 230 and the lifting assembly 110 are simultaneously located on the Y-axis. The pipes are also placed in the Y-axis direction during loading to ensure that when the pipes reach the chute assembly 230, the lifting assembly 110 can lift them. More specifically, the lifting assembly 110 is generally located on the left and right sides of the corresponding loading chute 231. The lifting assembly 110 typically includes a roller structure horizontally arranged along the X-axis. Some pipe cutting machines also have variable diameter wheels to adjust the position of the pipes. The lifting assembly 110 is driven to move up and down by a cylinder, lifting the pipes through this roller structure. Additionally, the pipe cutting machine 100 typically has a front clamping assembly and a rear clamping assembly for clamping and processing the lifted pipes after loading. Traditional semi-automatic feeding racks typically only have chains and stops for conveying pipes. Once the pipes are in place, the feeding rack stops and is lifted by the roller structure of the lifting assembly 110. Since the roller structure is set along the X-axis, corresponding to the moving direction of the conveyor chain 224, and the roller structure must be set to a certain length to ensure that it can lift pipes of various specifications, the spacing between the stops in traditional feeding racks needs to be relatively large to ensure that the distance between two pipes is sufficient during feeding. Otherwise, if the distance is too close, the lifting assembly may lift two pipes at the same time, resulting in feeding program errors. This invention uses a chute assembly 230 to allow the positioned pipe to slide forward onto the feeding trough 231 on its own, ensuring that the lifting assembly 110 supports one pipe and guaranteeing stable feeding. Because of the chute assembly 230, the distance between the stops 223 can be set to be smaller. The pipe does not need to be driven to the lifting position by the stops 223, but can slide to the lifting position on its own after it reaches the guide plate 232. The advantage of a closer distance between the stops 223 is that more stops 223 can be set on the same length of the conveyor chain 224. Therefore, the same length of the conveyor assembly 220 on the X-axis can simultaneously hold more pipes to be fed, reducing the number of operations required by the operator. Alternatively, when placing the same number of pipes, the length of the support 210 on the X-axis can be smaller, saving space occupied by the equipment.

[0029] Furthermore, the bracket 210 is provided with multiple support feet 211 and multiple connecting feet 212 for connecting the pipe cutter 100. The support feet 211 are used to connect the bracket 210 to the ground to support the loading rack 200, while the shorter connecting feet 212 can be connected to the bed of the pipe cutter 100, which can support the loading rack 200 and connect the pipe cutter 100 at the same time, ensuring the stability when feeding materials to the pipe cutter 100.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
