Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a guide structure for a bending machine for processing smoke exhaust ducts. Background Technology

[0002] During the processing of the exhaust duct, the thin plate needs to be bent several times by a bending machine to form a square duct. Specifically, the extrusion pressure generated by the closing of the upper and lower dies in the bending machine causes the metal plate to undergo plastic deformation outside the yield point, forming a permanent bend. In order to improve the stability of the upper die during the up-and-down reciprocating movement, a guide mechanism is also set to prevent the upper die from shifting its position during the movement.

[0003] The existing guiding mechanism consists of a slide rail and a slider. The slider is connected to the upper die, while the slide rail is installed outside the housing of the bending machine. When the upper die drives the slider to slide in the groove of the slide rail, the groove needs to be filled with lubricating oil to reduce friction between the two and extend their service life. In the existing technology, the lubricating oil is usually applied manually. The disadvantage of this method is that the bending machine needs to be stopped before the lubricating oil can be applied to the surface of the slider and the groove manually in a safe state. However, there is more than one guiding mechanism in the bending machine, which requires at least two sets. Therefore, the manual application method will occupy the working time of the bending machine, thereby reducing the processing efficiency of the bending machine. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a guide structure for a smoke exhaust duct processing bending machine.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a guide structure for a smoke exhaust duct bending machine, comprising a slider and a slide rail. The slider is placed in the slide groove of the slide rail. Oiling blocks are installed at the top and bottom of the slider. The oiling blocks have cavities inside, and support plates are provided in the cavities. Oil outlet holes are provided on the surface of the support plates. Three oil outlets are provided at the bottom of the oiling blocks, and the three oil outlets correspond to the three surfaces of the slide groove. An oil supply pipe is installed through the top of the oiling blocks, and one end of the oil supply pipe is connected to an oil supply mechanism.

[0006] Preferably, the oil supply mechanism includes a lubricating oil tank, a micro gear pump is installed on the top of the lubricating oil tank, the oil inlet of the micro gear pump passes through the top of the lubricating oil tank through an oil pipe and extends into the interior therein, and the oil outlet of the micro gear pump is connected to the oil delivery pipe through a multi-port pipe.

[0007] Preferably, an annular inclined block is installed on the top of the support plate, and the annular inclined block is arranged coaxially with the oil outlet.

[0008] Preferably, a fixing pipe is installed on the inner top surface of the cavity, and an installation rod is elastically connected to the bottom end of the fixing pipe. One end of the installation rod passes through the oil outlet and extends to the bottom of the support plate. A blocking plate is installed on one end of the installation rod, and a sealing rubber ring is installed on the top of the blocking plate. The top of the sealing rubber ring is connected to the bottom of the support plate.

[0009] Preferably, an annular stop is installed at the bottom end of the fixed pipe fitting, the mounting rod is inserted into the inner hole of the annular stop, one end of the mounting rod extends into the interior of the fixed pipe fitting, a limit block is installed at the top end of the mounting rod, and a compression spring is movably sleeved on the surface of the mounting rod, with both ends of the compression spring connected to the limit block and the annular stop respectively.

[0010] Preferably, an oil guide block is installed on the inner bottom surface of the cavity, and the inclined surface of the oil guide block corresponds to the position of the three oil outlets.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This solution involves installing two oiling blocks at the top and bottom of the slider. The two oiling blocks are supplied with lubricating oil through an oil supply mechanism and delivered to the cavity above the support plate. The lubricating oil falls through the oil outlet into the cavity below the support and finally flows out from the three oil outlets to the three surfaces of the slide rail for lubrication.

[0017] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0018] like Figure 1-3 The diagram shows a guide structure for a smoke exhaust duct bending machine, comprising a slider 1 and a slide rail 2. The slider 1 is placed in a groove in the slide rail 2. Oiling blocks 5 are installed at both the top and bottom of the slider 1. Each oiling block 5 has an internal cavity containing a support plate 7, which divides the cavity in two. The cavity on the support plate 7 temporarily stores some lubricating oil. When lubrication is needed, a micro gear pump 3 can continue to supply lubricating oil, facilitating the flow of lubricating oil from the oil outlet 10 into the cavity below the support plate 7. This, in turn, facilitates the flow of lubricating oil from the three oil outlets 8 to the three surfaces of the slide rail.

[0019] The surface of the support plate 7 is provided with an oil outlet hole 10, which allows the lubricating oil in the cavity above the support plate 7 to be transported to the cavity below the support plate 7, thereby facilitating the flow of lubricating oil from the three oil outlets 8.

[0020] The bottom of the oiling block 5 has three oil outlets 8, which correspond to the three surfaces of the slide groove. The three oil outlets 8 can deliver lubricating oil to the three surfaces of the slide groove, which can lubricate the inside of the slide rail 2.

[0021] An oil supply pipe is installed through the top of the oiling block 5. One end of the oil supply pipe is connected to an oil supply mechanism, which includes a lubricating oil tank 4. A micro gear pump 3 is installed on the top of the lubricating oil tank 4. The oil inlet of the micro gear pump 3 passes through the top of the lubricating oil tank 4 through an oil pipe and extends into its interior. The oil outlet of the micro gear pump 3 is connected to the oil supply pipe through a multi-port pipe. The micro gear pump 3 delivers the lubricating oil in the lubricating oil tank 4 to the two oil supply pipes through the oil pipe, thereby delivering the lubricating oil to the cavities of the two oiling blocks 5.

[0022] An annular inclined block 6 is installed on the top of the support plate 7. The annular inclined block 6 is arranged coaxially with the oil outlet 8. After the lubricating oil is delivered to the cavity above the support plate 1, the lubricating oil is delivered to the surrounding area of ​​the oil outlet 8 through the inclined surface of the annular inclined block 6. This reduces the amount of lubricating oil residue on the support plate 7, increases the volume of lubricating oil flowing out of the oil outlet 8, and thus improves the delivery efficiency of the lubricating oil.

[0023] A fixed pipe fitting 13 is installed on the top surface of the cavity. The bottom end of the fixed pipe fitting 13 is elastically connected to an installation rod 12. One end of the installation rod 12 passes through the oil outlet 10 and extends to the bottom of the support plate 7. A blocking plate 11 is installed on one end of the installation rod 12. A sealing rubber ring 14 is installed on the top of the blocking plate 11. The top of the sealing rubber ring 14 is connected to the bottom of the support plate 7. An annular stop block 15 is installed at the bottom end of the fixed pipe fitting 13. The installation rod 12 is inserted into the inner hole of the annular stop block 15. One end of the installation rod 12 extends into the interior of the fixed pipe fitting 13. A limit block 17 is installed at the top end of the installation rod 12. A compression spring 16 is movably sleeved on the surface of the installation rod 12. The two ends of the compression spring 16 are connected to the limit block 17 and the annular stop block 15, respectively. Lubricating oil is delivered to the cavity above the support plate 7 by the micro gear pump 3. As more and more lubricating oil accumulates, when the pressure is sufficient to push the blocking plate 11, the blocking plate 11 pulls the mounting rod 12. The mounting rod 12 moves the limiting block 17, which applies a force to the compression spring 16. The compression spring 16 contracts under this force, and simultaneously, the blocking plate 11 causes the sealing rubber ring 14 to separate from the bottom of the support plate 7. The lubricating oil then flows out from the gap between the sealing rubber ring 14 and the support plate 7 into the cavity below the support plate 7, and finally flows out from the three oil outlets 8 to the three surface positions in the slide groove, thus lubricating the slide groove of the slide rail. Function: When lubrication needs to be stopped, simply stop the operation of the micro gear pump 3 and stop supplying lubricating oil. As the amount of lubricating oil in the cavity decreases, the pressure of the lubricating oil in the cavity above the support plate 7 gradually decreases, thus reducing the pressure on the blocking plate 11. When the external pressure is less than the elastic potential energy of the compression spring 16, the compression spring 16 pushes the limiting block 17 in the opposite direction. The limiting block 17 pulls the mounting rod 12 upward, and the mounting rod 12 pulls the blocking plate 11 upward. The blocking plate 11 drives the sealing rubber ring 14 to press against the bottom of the support plate 7, sealing the oil outlet 10, thereby stopping the lubricating oil from continuing to flow into the cavity below the support plate 7, thus stopping the application of lubricating oil.

[0024] An oil guide block 9 is installed on the bottom surface of the cavity. The inclined surface of the oil guide block 9 corresponds to the position of the three oil outlets 8. After the lubricating oil flows to the surface of the oil guide block 9, it will flow along the inclined surface of the oil guide block 9 to the position of the three oil outlets 8, thus facilitating the guidance of the lubricating oil.

[0025] In this solution, the micro gear pump 3 is connected to a power switch or PLC via a wire, and the power switch or PLC is connected to an external power source via a wire, which facilitates the control of the micro gear pump 3 as needed.

[0026] In this design, the lubricating oil tank 4 can be mounted on the outer surface of the bending machine via a bracket.

[0027] Working principle: When lubricating oil is applied to the inside of the slide groove of slide rail 2, the bending machine works synchronously. At this time, the upper mold drives the slider 1 to slide in the slide groove of slide rail 2.

[0028] The micro gear pump 3 drives the lubricating oil to be delivered to the cavities of the two oiling blocks 5. As more and more lubricating oil accumulates in the cavity above the support plate 7, when the pressure of the accumulated lubricating oil is sufficient to push the blocking plate 11, the blocking plate 11 pulls the mounting rod 12 after being subjected to force. The mounting rod 12 drives the limiting block 17 to move. The limiting block 17 applies force to the compression spring 16. The compression spring 16 contracts after being subjected to force. At the same time, the blocking plate 11 drives the sealing rubber ring 14 to separate from the bottom of the support plate 7. The lubricating oil flows out from the gap between the sealing rubber ring 14 and the support plate 7 into the cavity below the support plate 7, and finally flows out from the three oil outlets 8 to the three surface positions in the slide groove, thereby lubricating the slide groove of the slide rail 2.

[0029] As the slider 1 moves up and down, it not only drives the oiling block 5 to move synchronously during the movement, but also allows the lubricating oil flowing out of the oiling block 5 to coat the surface of the slide groove of the slide rail 2 with lubricating oil. Furthermore, the length of the coated lubricating oil is greater than the moving stroke of the slider 1. During the movement, the slider 1 also comes into contact with the lubricating oil, thus providing lubrication for both the slide rail 2 and the slider 1.
