Description

Technical Field

[0001] The invention relates to the technical field of building HVAC engineering, in particular to a HVAC pipe cutting device for building HVAC engineering. Background Art

[0002] In building HVAC engineering, HVAC pipe cutting device is a device used to cut pipes, which is widely used in pipe installation, maintenance and modification in HVAC systems. It can effectively improve the efficiency and accuracy of pipe cutting and ensure the good operation of the system.

[0003] The patent with patent announcement number CN222176783U relates to a HVAC pipe cutting device for building HVAC engineering, including: an operating panel and a cylinder, legs are fixedly installed on the four sides of the lower end of the operating panel, a discharge port is opened at one end of the operating panel, a collecting trough is fixedly installed at the lower end of the discharge port, and the cylinder is rotatably connected to the upper end of the operating panel. The HVAC pipe to be cut is passed through the clamping plate and the limit block, and then the threaded rod is rotated to drive the clamping plate to move downward, so that the clamping plate and the upper end of the HVAC pipe are in contact, thereby fixing the HVAC pipe. At this time, the pipe can be cut by the cutting equipment. When multiple pipes need to be rotated, the pipe can be rotated by starting the motor to drive the cylinder to rotate, and then the pipe can be cut again, thereby realizing circular cutting. Compared with the existing manual adjustment cutting method, it has a higher degree of automation and is more time-saving and labor-saving.

[0004] In the above patent, by starting the motor to drive the cylinder to rotate, the pipe can be rotated, and then the pipe can be cut again to achieve circular cutting. Compared with the existing manual adjustment cutting method, it has a higher degree of automation and is more time-saving and labor-saving. However, in the process of multiple segmented cutting of the same pipe, it is relatively cumbersome when manual adjustment of the position of the pipe is required and repeated operations are performed. Therefore, a HVAC pipe cutting device for building HVAC engineering with a better feeding device is designed. Summary of the invention

The ratchet wheel rotates counterclockwise to drive the rotating rod to rotate counterclockwise, and the rotating rod rotates counterclockwise to drive the feeding plate to move toward the driven platform under the action of the spiral groove. The movement of the feeding plate will push the pipe to be cut to move and contact the baffle, so that the reciprocating movement can effectively realize multiple feeding and cutting of the pipe, and the pipe can be cut into multiple parts at one time without the need for staff to continuously push the material.

[0007] According to the above technical solution, the feeding table is slidably connected to the top of the workbench, and a spring No. 1 is arranged between the arc block and the inner wall of the slide groove 1. The arc block moves downward to squeeze the spring No. 1 and then returns to its original position after contraction.

[0008] According to the above technical solution, two electric push rods are provided, and the electric push rod on the left side is fixedly connected to the driven table, and the driven table and the feeding table move synchronously to facilitate the cutting of the pipeline.

[0009] According to the above technical scheme, a stabilizing device for preventing the pipeline from shaking is provided on the surface of the feeding table, and the stabilizing device includes a lifting plate, a slide groove 2 is opened on the surface of the feeding table, and the lifting plate is slidably installed in the inside of the slide groove 2, a fixed block is fixedly installed above the workbench, and a connecting rod is rotatably installed on the surface of the fixed block, a slide groove 3 is opened on the surface of the lifting plate, and a lifting block is slidably installed in the inside of the slide groove 3, and a lifting rod is slidably penetrated on the surface of the lifting plate, and a connecting block is rotatably installed below the lifting rod, and a pressing plate is fixedly installed below the connecting block, and the connecting block moves downward to drive the pressing plate to move downward, and the pressing plate moves downward to contact and press the pipeline, which can effectively avoid shaking when cutting the pipeline and improve the flatness of the cutting surface.

[0010] According to the above technical solution, one end of the connecting rod away from the fixed block is rotatably connected to the lifting block, and a No. 2 spring is arranged between the lifting rod and the lifting plate. After the pressure plate contacts the pipeline, it will drive the connecting block and the lifting rod to move upward under its action, and the lifting rod moves upward to stretch the No. 2 spring.

[0011] According to the above technical solution, a lifting plate is also provided on the surface of the driven platform, and the pressure plate is elastic.

A fixed groove is opened on the surface of the baffle, and a roller is rotatably installed inside the fixed groove. The end of the connecting rod away from the receiving rod is rotatably connected to the moving rod. When the cutting is completed, the pipe after cutting will be ejected during the process of continuing to feed the pipe, and the ejected pipe will move with the assistance of the roller above the baffle.

[0013] According to the above technical solution, a No. 3 spring is arranged between the baffle and the bottom of the inner wall of the limiting groove.

The end of the moving rod away from the connecting rod is set as a bevel surface, and the lifting plate moves downward to squeeze the moving rod through the bevel surface to move toward the direction close to the baffle.

[0014] The present invention provides a HVAC pipe cutting device for building HVAC engineering. It has the following beneficial effects: (1) The HVAC pipe cutting device for building HVAC engineering uses an electric push rod to drive the feeding table to move back and forth, so that the feeding table can complete the feeding of the pipe during the moving cutting process. The pipe can be cut into multiple pieces at one time without the need for workers to continuously push the material. At the same time, the reciprocating movement distance of the electric push rod can be controlled to achieve the cutting of pipes of different required lengths, thereby improving the applicability of the equipment.

[0015] (2) In the HVAC pipe cutting device for building HVAC engineering, when the pipe needs to be relocated, the output end of the electric push rod moves further away from the cutting mechanism, so that the ratchet is out of the range of action of the arc block. The feed plate can then be moved and reset to complete the subsequent placement of the pipe, greatly improving the efficiency of pipe cutting.

[0016] (3) The HVAC pipe cutting device used in the building HVAC project, when the feed table moves toward the cutting mechanism, drives the lifting plate to move toward the cutting mechanism, drives the lifting block and the lifting plate downward through the fixed block and the connecting rod, and drives the connecting block and the pressing plate downward through the lifting plate and the lifting rod to contact and press the pipe, which can effectively avoid shaking when cutting the pipe and improve the flatness of the cutting surface.

[0017] (4) The HVAC pipe cutting device used in the HVAC project of this building, after the pressure plate contacts the pipe, it will drive the connecting block and the lifting rod to move upward under its action. The upward movement of the lifting rod causes the No. 2 spring to stretch, which can avoid excessive squeezing of the pipe and achieve effective clamping of pipes with different outer diameters. In this process, the pressure plate will be deformed under the action of the pipe. The deformed pressure plate will increase the contact area with the pipe, further improving the clamping and stabilizing effect of the pipe and improving the cutting effect of the pipe.

[0018] (5) The HVAC pipe cutting device used in the HVAC engineering of this building, when the lifting plate moves downward, drives the baffle plate to move downward through the moving rod and the connecting rod. The baffle plate moves downward to squeeze the No. 3 spring to contract. When the cutting is completed, the contracted No. 3 spring will lift the baffle plate again and re-limit the subsequent pipes, which can effectively limit the pipes and assist in their discharge. During this process, the pipes are clamped stably by the pressure plate. When the cutting is completed, the pipes will be pushed out during the continuous feeding process. The pushed out pipes will move with the assistance of the rollers above the baffle plate, thereby improving the cutting efficiency of the pipes. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-Figure 7 One embodiment of the present invention is: a HVAC pipe cutting device for building HVAC engineering, comprising a workbench 1, a cutting mechanism 2 is arranged above the workbench 1, a feeding device for feeding the pipe is arranged above the workbench 1, the feeding device comprises an electric push rod 3, the electric push rod 3 is fixedly installed above the workbench 1, a feeding table 4 is fixedly installed on the output end of the electric push rod 3, a feeding plate 5 is slidably installed on the surface of the feeding table 4, a rotating rod 6 is rotatably penetrated on the surface of the feeding table 4, a ratchet 7 is fixedly installed on the circumferential surface of the rotating rod 6, a slide groove 8 is opened on the surface of the workbench 1, an arc block 9 is slidably installed inside the slide groove 8, and the surface of the rotating rod 6 A spiral groove is provided on the surface, and the feeding plate 5 and the rotating rod 6 are threadedly connected through the spiral groove. A driven table 10 is slidably installed above the workbench 1, and a limiting groove 11 is provided on the surface of the driven table 10. A baffle 12 is slidably installed inside the limiting groove 11. The ratchet 7 rotates counterclockwise to drive the rotating rod 6 to rotate counterclockwise. The rotating rod 6 rotates counterclockwise and drives the feeding plate 5 to move toward the driven table 10 under the action of the spiral groove. The movement of the feeding plate 5 will push the pipe to be cut to move and contact the baffle 12. The reciprocating movement can effectively realize multiple feeding and cutting of the pipe, and the pipe can be cut into multiple parts at one time without the need for the staff to continuously push the material.

[0023] The feeding table 4 is slidably connected to the top of the workbench 1, and a spring 13 is arranged between the arc block 9 and the inner wall of the slide groove 8. The arc block 9 moves downward to squeeze the spring 13 and then shrinks and resets, which can effectively prevent the ratchet 7 from rotating clockwise during the cutting process, causing the feeding plate 5 to loosen and thus affecting the pipe cutting effect.

[0024] Two electric push rods 3 are provided, and the left electric push rod 3 is fixedly connected to the driven table 10. The driven table 10 and the feeding table 4 move synchronously to facilitate the cutting of the pipeline.

[0025] When this embodiment is working: the pipe to be cut is placed above the feeding table 4, and then the electric push rod 3 is started. When the output end of the electric push rod 3 moves in the direction away from the cutting mechanism 2, it will drive the feeding table 4 to move. The movement of the feeding table 4 drives the rotating rod 6 to move. The movement of the rotating rod 6 drives the ratchet 7 to move. When the ratchet 7 moves, it contacts the arc block 9 and rotates counterclockwise under the action of the arc block 9. The counterclockwise rotation of the ratchet 7 drives the rotating rod 6 to rotate counterclockwise. The counterclockwise rotation of the rotating rod 6 drives the feeding plate 5 to move in the direction close to the driven table 10 under the action of the spiral groove. The movement of the feeding plate 5 will push the pipe to be cut to move and contact the baffle 12, and realize the lateral restriction of the pipe to be cut. Then the output end of the electric push rod 3 moves in the direction close to the cutting mechanism 2 and drives the feeding table 4 to move. The movement of the feeding table 4 drives the pipe to be cut to move and cuts the pipe under the action of the cutting mechanism 2. During cutting, the ratchet 7 moves to contact and squeeze the arc block 9 to move downward, and the arc block 9 moves downward to squeeze the No. 1 spring 13 to shrink and then reset, which can effectively prevent the ratchet 7 from rotating clockwise during the cutting process, causing the feeding plate 5 to loosen and thus affecting the pipe cutting effect. Subsequently, this reciprocating movement can effectively realize multiple feeding and cutting of the pipe, and can cut the pipe into multiple parts at one time without the need for staff to continuously push the material. At the same time, the reciprocating movement distance of the electric push rod 3 can be controlled to achieve the cutting of pipes of different required lengths, thereby improving the applicability of the equipment. When the pipe needs to be replaced, the output end of the electric push rod 3 moves further in the direction away from the cutting mechanism 2, so that the ratchet 7 is out of the action range of the arc block 9, and the subsequent pipe placement can be completed by moving the feeding plate 5 and resetting it, thereby greatly improving the cutting efficiency of the pipe.

[0026] See also Figure 1-Figure 7On the basis of the above embodiment, in another embodiment of the present invention, a stabilizing device for preventing the pipeline from shaking is provided on the surface of the feeding table 4, and the stabilizing device includes a lifting plate 141, a second slide groove 142 is provided on the surface of the feeding table 4, and the lifting plate 141 is slidably installed inside the second slide groove 142, a fixed block 143 is fixedly installed above the workbench 1, and a connecting rod 144 is rotatably installed on the surface of the fixed block 143, a slide groove 3 145 is provided on the surface of the lifting plate 141, and a lifting block 146 is slidably installed inside the slide groove 3 145, and a lifting rod 147 is slidably penetrated on the surface of the lifting plate 141, and a connecting block 148 is rotatably installed below the lifting rod 147, and a pressing plate 149 is fixedly installed below the connecting block 148, and the connecting block 148 moves downward to drive the pressing plate 149 to move downward, and the pressing plate 149 moves downward to contact and press the pipeline, which can effectively avoid shaking when cutting the pipeline and improve the flatness of the cutting surface.

[0027] One end of the connecting rod 144 away from the fixed block 143 is rotatably connected to the lifting block 146, and a No. 2 spring 1410 is arranged between the lifting rod 147 and the lifting plate 141. After the pressure plate 149 contacts the pipeline, it will drive the connecting block 148 and the lifting rod 147 to move upward under its action. The upward movement of the lifting rod 147 causes the No. 2 spring 1410 to stretch, which can avoid excessive extrusion of the pipeline and realize effective clamping of pipelines with different outer diameters.

[0028] The surface of the driven table 10 is also provided with a lifting plate 141, and the pressure plate 149 is elastic. The pressure plate 149 will be deformed under the action of the pipeline. The deformed pressure plate 149 will increase the contact area with the pipeline, further improve the clamping and stabilizing effect of the pipeline, and improve the cutting effect of the pipeline.

[0029] The surface of the baffle 12 is provided with a discharge device for discharging the cut pipe, and the discharge device includes a receiving rod 151, which is fixedly installed on the surface of the baffle 12, and a connecting rod 152 is rotatably installed on the circumferential surface of the receiving rod 151, and a moving rod 153 is slidably installed on the top of the inner wall of the limiting groove 11. A fixed groove 154 is opened on the surface of the baffle 12, and a roller 155 is rotatably installed inside the fixed groove 154. The end of the connecting rod 152 away from the receiving rod 151 is rotatably connected to the moving rod 153. When the cutting is completed, the pipe after cutting will be ejected during the continuous feeding of the pipe, and the ejected pipe will move above the baffle 12 with the assistance of the roller 155.

[0030] A No. 3 spring 156 is arranged between the baffle 12 and the bottom of the inner wall of the limiting groove 11. The contracted No. 3 spring 156 will lift the baffle 12 again and re-limit the subsequent pipeline, which can effectively limit the pipeline and assist its material discharge, thereby improving the cutting efficiency of the pipeline. The end of the moving rod 153 away from the connecting rod 152 is set as a bevel surface, and the lifting plate 141 moves downward to squeeze the moving rod 153 through the bevel surface to move towards the direction close to the baffle 12.

[0031] When the present embodiment is working, the feeding table 4 drives the lifting plate 141 to move in the direction close to the cutting mechanism 2 when it moves in the direction close to the cutting mechanism 2. The lifting plate 141 moves horizontally and moves downward under the action of the fixing block 143 and the connecting rod 144. The lifting plate 141 moves downward and drives the lifting rod 147 to move downward. The lifting rod 147 moves downward and drives the connecting block 148 to move downward. The connecting block 148 moves downward and drives the pressing plate 149 to move downward. The pressing plate 149 moves downward and contacts the pipe and presses it, which can effectively avoid the pipe from being pressed. The pipeline will shake during cutting, which improves the flatness of the cutting surface. At the same time, after the pressure plate 149 contacts the pipeline, it will drive the connecting block 148 and the lifting rod 147 to move upward. The lifting rod 147 moves upward to stretch the second spring 1410, which can avoid excessive squeezing of the pipeline and achieve effective clamping of pipelines with different outer diameters. In this process, the pressure plate 149 will be deformed under the action of the pipeline. The deformed pressure plate 149 will increase the contact area with the pipeline, further improving the clamping and stabilizing effect of the pipeline and improving the cutting effect of the pipeline.

[0032] When this embodiment is working: when the lifting plate 141 moves downward, it contacts and squeezes the moving rod 153 to move in the direction close to the baffle 12. The movement of the moving rod 153 drives one end of the connecting rod 152 to move in the direction close to the baffle 12. One end of the connecting rod 152 moves through the other end to drive the baffle 12 to move downward. The baffle 12 moves downward to release the obstruction to the pipeline. During this process, the pipeline is clamped and stabilized by the pressing plate 149. After the cutting is completed, the pipeline will continue to feed the material and the pipeline after cutting will be ejected. The ejected pipeline will move with the assistance of the roller 155 above the baffle 12. When the baffle 12 moves downward, it will squeeze the No. 3 spring 156 to contract. When the subsequent pipeline moves in the direction close to the driven table 10, the contracted No. 3 spring 156 will re-lift the baffle 12 and re-limit the subsequent pipeline, which can effectively limit the pipeline and assist its discharge, thereby improving the cutting efficiency of the pipeline.
