Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a slot forming device. Background Technology

[0002] Telescopic ladders are a new type of movable staircase. Because they can be flexibly extended and retracted, they offer advantages over traditional fixed-length ladders, such as taking up less space and being easier to store and carry. Telescopic ladders can be used as stairs in various scenarios, including homes, boats, and construction projects, and have huge market potential. The steel pipes of telescopic ladders need to be machined with slots for extending the ladder; these slots are typically formed using specific processes.

[0003] For example, patent document No. 202122736008.2, entitled "Automatic Gap Forming Machine," describes a device for processing grooves on steel pipes. During operation, the telescopic ladder pipe is first placed between the first and second rotating shafts and limited by a pipe limiting block. Then, a first motor drives the first and second rotating shafts to rotate synchronously, thereby rotating the pipe. Simultaneously, a lifting cylinder drives the cutting mechanism to press down, and a second motor drives the blade disc to rotate, causing the blade disc to roll out a groove on the rotating pipe. The depth of the groove can be controlled by adjusting the lifting cylinder, achieving automated processing.

[0004] However, this forming machine has certain limitations in practical applications. It can only place one steel pipe for processing at a time, and it can only be removed after forming is completed before the next steel pipe is placed in for roll forming, resulting in low continuity of steel pipe processing. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a slot forming device that can improve the continuity of steel pipe processing.

[0006] To solve the above-mentioned technical problems, the present invention provides a slot forming device, comprising:

[0007] frame;

[0008] A conveyor belt, mounted on a frame, is used to horizontally transport steel pipes from front to back.

[0009] A limiting belt is installed on the frame and positioned above the conveyor belt and runs in the opposite direction to the drive belt. The limiting belt is provided with a limiting groove for limiting the swing of the steel pipe.

[0010] The limiting guide rail includes two limiting plates spaced apart on the left and right sides to limit the left or right end of the steel pipe;

[0011] And the cutter head, mounted on the frame and used to roll out the locking grooves on the steel pipe.

[0012] As an improvement to the above solution, the limiting belt is provided with multiple limiting seats that are equidistantly spaced along the running direction of the limiting belt, and the limiting groove is provided on the limiting seat and extends to the left and right.

[0013] As an improvement to the above solution, the limiting groove includes an arc groove and a guide groove that communicates with the arc groove and whose width increases sequentially in the direction away from the conveying surface of the limiting belt.

[0014] As an improvement to the above solution, the positioning groove forming device of this utility model also includes a flow guide rail disposed on the front side of the limiting guide rail. The flow guide rail includes two flow guide plates disposed on the front end of the two limiting plates respectively, with the distance between them gradually decreasing from front to back.

[0015] As an improvement to the above solution, the lower front side of the cutter head is inclined downward from front to back, and the lower rear side of the cutter head extends horizontally from front to back.

[0016] As an improvement to the above solution, the length of the front part of the cutter head is greater than the outer diameter of the steel pipe.

[0017] As an improvement to the above solution, the length of the rear part of the cutter head is greater than three times the outer diameter circumference of the steel pipe.

[0018] As an improvement to the above solution, the slot forming device of this utility model also includes a pressure plate installed on the frame and used to abut against the upper end of the steel pipe, and the cutter head and the pressure plate are respectively provided with limiting bands on the left and right sides.

[0019] As an improvement to the above solution, the slot forming device of this utility model further includes a first height adjustment mechanism and a second height adjustment mechanism installed on the frame. The cutter head is installed at the output end of the first height adjustment mechanism, and the pressure plate is installed at the output end of the second height adjustment mechanism.

[0020] Implementing this utility model has the following beneficial effects:

[0021] The slot forming device of this utility model, through the cooperation of a frame, conveyor belt, limiting belt, limiting guide rail and cutter head, can move multiple steel pipes placed between the limiting belt and the conveyor belt from front to back and automatically roll out slots when they come into contact with the cutter head. There is no need to wait for the previous steel pipe to be processed to form a slot before the steel pipe to be processed can be put between the conveyor belt and the limiting belt. Moreover, during the process of the conveyor belt and the limiting belt cooperating to transport the steel pipes, the processed steel pipes are output one by one, which improves the continuity of steel pipe processing.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings.

[0040] like Figures 1 to 6 As shown in the figure, a slot forming device in an embodiment of the present invention includes a frame 100, a conveyor belt 200, a limiting belt 300, a limiting guide rail 400, and a cutting head 500.

[0041] The conveyor belt 200 is mounted on the frame 100 and is used to horizontally transport steel pipes from front to back. In practice, the conveyor belt 200 can be a belt conveyor belt with a conveying surface arranged parallel to the horizontal plane. When the steel pipe to be processed is placed on the conveying surface of the conveyor belt 200 in a left-right orientation, the conveyor belt 200 can drive the steel pipe to move backward.

[0042] The limiting belt 300 is mounted on the frame 100 and positioned above the conveyor belt 200, running in the opposite direction to the drive belt. The limiting belt 300 is provided with a limiting groove 310 for restricting the swaying of the steel pipe. In fact, as... Figure 2 As shown, the conveyor belt 200 runs counterclockwise, while the limiting belt 300 runs clockwise. The steel pipe to be processed is placed at the front of the conveyor belt 200 and is inserted into the limiting groove 310 of the limiting belt 300 during the conveying process, or it is directly inserted into the limiting groove 310 during loading. Through the synergistic effect of the conveyor belt 200 and the limiting belt 300 in the limiting groove 310, the steel pipe is conveyed from front to back, and the steel pipe is prevented from swinging during the conveying process, ensuring that the angle of the clamping groove processed on the steel pipe is consistent.

[0043] The limiting guide rail 400 includes two limiting plates 410 spaced apart on the left and right sides to limit the left or right end of the steel pipe. Specifically, the right side of the left limiting plate 410 abuts against the left end of the steel pipe, and the left side of the right limiting plate 410 abuts against the right end of the steel pipe. The distance between the two limiting plates 410 matches the length of the steel pipe, ensuring that the steel pipe's axis remains horizontally extended when it passes between the limiting guide rails 400, thus preventing left and right movement of the steel pipe.

[0044] The cutter head 500 is mounted on the frame 100 and is used to roll out a locking groove on the steel pipe. In fact, the cross-section of the cutter head 500 is as follows: Figure 4 As shown, Figure 2 As shown, during the process of the steel pipe moving from front to back, the outer side of the steel pipe contacts the lower part of the cutter head 500, and the steel pipe rotates during the contact with the lower part of the cutter head 500. During the rotation of the steel pipe, the lower part of the cutter head 500 squeezes the outer side of the steel pipe and processes a complete and circular locking groove.

[0045] It should be noted that the conveyor speed of the conveyor belt 200 can be the same as that of the limiting belt 300, and the friction force drives the steel pipe to rotate passively during the contact between the cutter head 500 and the outer side of the steel pipe; alternatively, the conveyor speed of the conveyor belt 200 can be different from that of the limiting belt 300, and the steel pipe rotates actively under the effect of the difference between the conveyor speed of the conveyor belt 200 and the limiting belt 300. Both methods can ensure that the steel pipe rotates during the contact between the outer side of the steel pipe and the cutter head 500. This utility model preferably adopts the method that the conveyor speed of the conveyor belt 200 can also be different from that of the limiting belt 300, so that the steel pipe rotates actively, ensuring that the spinning of the steel pipe to form the positioning groove is more controllable.

[0046] The slot forming device of this utility model, through the cooperation of the frame 100, conveyor belt 200, limiting belt 300, limiting guide rail 400 and cutter head 500, can move multiple steel pipes placed between the limiting slot 310 of the limiting belt 300 and the conveyor belt 200 from front to back and automatically roll out slots by contacting the cutter head 500. There is no need to wait for the previous steel pipe to be processed to form a slot before the steel pipe to be processed can be put between the conveyor belt 200 and the limiting belt 300. During the process of the conveyor belt 200 and the limiting belt 300 cooperating to transport the steel pipes, the processed steel pipes are output one by one, which improves the continuity of steel pipe processing.

[0047] Specifically, such as Figure 1 and Figure 2 As shown, the limiting belt 300 preferably has a plurality of limiting seats 320 equidistantly spaced along the running direction of the limiting belt 300. The limiting groove 310 is disposed on the limiting seat 320 and extends to the left and right. By placing the limiting groove 310 on the limiting seat 320, compared to placing the limiting groove 310 directly on the conveyor belt of the limiting belt 300, the limiting seat 320 provides stable support for the limiting groove 310, making the positioning of the steel pipe more accurate during transportation and effectively improving the processing accuracy. The limiting seat 320 can distribute the weight and inertial force of the steel pipe, reduce the shaking of the limiting belt 300, and enhance the stability of the limiting belt 300. In addition, the limiting seat 320 can be designed as a detachable or adjustable structure, which is convenient for adjustment or replacement according to different steel pipe specifications and facilitates maintenance.

[0048] More specifically, the limiting groove 310 preferably includes an arcuate groove 311 and a guide groove 312 that communicates with the arcuate groove 311 and whose width increases sequentially along the direction away from the conveying surface of the limiting band 300. For example... Figure 2As shown, when the steel pipe is placed at the front of the upper side of the conveyor belt 200, the conveyor belt 200 will move the steel pipe from front to back. During the movement, under the guidance of the guide groove 312, the steel pipe will gradually and accurately enter the arc groove 311. Through the cooperation between the arc groove 311 and the guide groove 312, the steel pipe undergoes an effective guiding process before officially entering the limiting groove 310. This guiding process enables the steel pipe to enter the limiting groove 310 more smoothly and accurately, thereby significantly improving the success rate of material feeding in the production process and ensuring the smooth operation of the production process.

[0049] It is worth mentioning that the slot forming device of this utility model preferably includes a guide rail 600 disposed on the front side of the limiting guide rail 400. The guide rail 600 includes two guide plates 610 correspondingly disposed at the front ends of the two limiting plates 410, with the distance between them gradually decreasing from front to back. Figure 1 As shown, during the process of placing the steel pipe onto the conveyor belt 200 and conveying it backward, the steel pipe may shift left or right. At this time, under the guidance of the two guide plates 610, the steel pipe can automatically adjust its position, move left and right and align with the opening of the limit guide rail 400, and smoothly enter the limit guide rail 400. This eliminates the need for operators to manually and precisely adjust the position of the steel pipe. They only need to roughly place the steel pipe on the conveyor belt 200, which simplifies the operation process and improves production efficiency.

[0050] Specifically, the lower front side of the cutter head 500 is inclined downwards from front to back, and the lower rear side of the cutter head 500 extends horizontally from front to back. In practice, during the operation of the automatic slot forming machine, the distance between the lower front side of the cutter head 500 and the conveyor belt 200 is designed to gradually decrease from front to back; this allows the cutter head 500 to achieve a smooth transition from initial contact to gradually reaching the predetermined processing depth when it contacts the steel pipe. The cutter head 500 initially separates from the outside of the steel pipe, then gradually contacts and finally penetrates to the required processing depth, thereby processing a slot on the outside of the steel pipe. This progressive processing method effectively reduces rigid collisions between the cutter head 500 and the steel pipe, reducing potential damage to the steel pipe due to sudden impacts, thus ensuring the stability of the processing and the quality of the final product.

[0051] Furthermore, the front length of the cutter head 500 is preferably greater than the outer diameter of the steel pipe, ensuring a sufficiently large contact area between the cutter head 500 and the steel pipe, thereby providing a smooth transition process for the steel pipe. Even further, the rear length of the cutter head 500 is preferably greater than three times the circumference of the outer diameter of the steel pipe, allowing the steel pipe sufficient distance to rotate during contact with the rear of the cutter head 500, thereby ensuring that the positioning groove can be completely machined.

[0052] It should be noted that the slot forming device of this utility model preferably also includes a pressure plate 700 mounted on the frame 100 and used to abut against the upper end of the steel pipe, and the cutter head 500 and the pressure plate 700 are respectively provided with limiting bands 300 on the left and right sides. In fact, as Figure 1 As shown, the cutter head 500 is positioned to the left of the limiting band 300, and the pressure plate 700 is positioned to the right of the limiting band 300. During the contact between the cutter head 500 and the upper part of the steel pipe, the pressure plate 700 also contacts the upper end of the steel pipe to ensure more even force distribution during processing. In practical applications, the positions of the cutter head 500 and the pressure plate 700 can be interchanged as needed.

[0053] Furthermore, the slot forming device of this utility model preferably includes a first height adjustment mechanism 800 and a second height adjustment mechanism 900 mounted on the frame 100. The cutter head 500 is mounted at the output end of the first height adjustment mechanism 800, and the pressure plate 700 is mounted at the output end of the second height adjustment mechanism 900. In practice, the first height adjustment mechanism 800 and the second height adjustment mechanism 900 can be in the form of a single-axis translation stage, a servo telescopic rod, a cylinder or hydraulic cylinder with an adjustable output end position, etc., capable of driving the cutter head 500 or the pressure plate 700 to move up and down to adjust their position. By adjusting the up and down position of the cutter head 500, it can accommodate steel pipes of different outer diameters, or adjust the processing depth of the slot on the outer side of the steel pipe. Adjusting the up and down position of the pressure plate 700 is mainly used to accommodate steel pipes of different outer diameters.
