Description

Technical Field

[0001] The present invention belongs to the technical field of automobile parts, and in particular relates to a cut-to-length device and method for producing a distribution pipe of a new energy automobile engine. Background Art

[0002] The extended-range engine (also called hybrid or electric extended-range engine) is one of the future trends in automobile development. It combines the traditional internal combustion engine and the electric power system to significantly improve fuel economy and reduce emissions. In this context, the engine distribution pipe, as one of the key engine components, is also facing new development prospects and challenges.

[0003] The preparation of the engine distribution pipe mainly includes the following steps: raw material inspection → cold rolling and degreasing → endoscope and ultrasonic testing → cutting to length → flat head, chamfering, boring → ultrasonic cleaning → full straightness inspection → full inner and outer wall inspection → finished product inspection → packaging and boxing → storage.

[0004] In the cut-to-length step of preparing the engine distribution pipe, the distance between the cutting device and the fixed point is often set so that the distribution pipe can be cut to a fixed length during the cutting process to meet the needs of automobile use.

[0005] Patent CN220372332U discloses a stainless steel pipe cut-to-length device, which effectively maintains the product length specification and size stability through the split design of the cutting part and the measuring part, avoids the phenomenon of long and short, and can realize the fixed length cutting of a steel pipe. In the technical solution of this patent, although the pipe can be cut to a fixed length, the cutting of the pipe needs to be completed step by step, which is inefficient.

[0006] Patent CN118455614A discloses a precision seamless steel pipe cut-to-length device and process, which can simultaneously cut multiple steel pipes in multiple sections by setting multiple support plates and cutting mechanisms on the support plates. In the technical solution of this patent, multiple pipes are cut simultaneously by multiple cutting machines, which improves the cutting efficiency of pipes to a certain extent.

[0007] In the technical solutions of the above patents, the pipes are cut to a fixed length. However, in actual application, the pipes are usually packed in steel strips (such as Figure 8 and Fig. 9 As shown in the figure, the pipe is transported to the cutting workshop and disassembled before cutting, which is rather cumbersome. Therefore, although the current technical solution has improved the efficiency of fixed-length cutting of pipes to a certain extent, it still has certain shortcomings. Summary of the invention

[0008] The purpose of the present invention is to provide a cut-to-length device and method for the production of new energy vehicle engine distribution pipes to solve the technical problem in the prior art that the distribution pipes packaged with steel strips need to be disassembled for cut-to-length cutting, resulting in reduced distribution pipe cutting efficiency.

[0009] The purpose of the present invention can be achieved through the following technical solutions:

[0010] A cut-to-length device for producing engine distribution pipes of new energy vehicles comprises a workbench and a distribution pipe body, wherein the distribution pipe body is packed into a pipe bundle by steel belts; a plurality of first incisions are evenly distributed on the workbench, and the first incisions are opened along the width direction of the workbench; a rotatable first hinge block and a movable second hinge block are respectively arranged at both ends of the first incision; a roller is connected to the upper parts of the first hinge block and the second hinge block corresponding to the same first incision for common rotation; the distribution pipe body is arranged on the roller, and the distribution pipe body is mounted along the length direction of the workbench; a transmission component is fixedly connected to one end of the roller, and the transmission component is used to drive the roller to rotate.

[0011] Preferably, the transmission assembly includes a transmission gear fixedly arranged at the end of the rotating roller; a second incision is opened at a position of the workbench close to the transmission gear, and the second incision is opened along the length direction of the workbench; the two ends of the second incision are rotatably connected to the first driving gear via an axle rod; a first chain is rotatably connected between the first driving gears, and the upper outer side of the first chain is meshed with the transmission gear; a first motor is fixedly arranged on the workbench.

[0012] Preferably, the transmission assembly includes a second chain rotatably connected to each transmission gear, the transmission gear meshes with the inner side of the second chain; the second chain is rotatably connected to a second driving gear corresponding to the position of the outermost transmission gear; and a second motor is fixedly arranged on the workbench.

[0013] Preferably, a transversely arranged fixed shaft is penetrated through the lower end of the first hinge block, and the fixed shaft is arranged in the length direction of the workbench, and both ends are fixedly connected to the workbench; a corresponding telescopic cylinder is arranged below the second hinge block, and the output end of the telescopic cylinder is rotatably connected to the corresponding lower end of the second hinge block; a fixed rod is fixedly connected to the position corresponding to the telescopic cylinder below the workbench; the fixed rod is rotatably connected to the lower part of the telescopic cylinder.

[0014] Preferably, guide plates are fixedly connected to the positions on both sides of the upper surface of the workbench corresponding to the first incision, the guide plate is higher at one end close to the first driving gear and lower at the other end, and the angle between the upper inclined surface and the workbench surface is set to 3°-8°.

[0015] Preferably, a limit plate is provided on one end of the workbench; a fixed block is fixedly connected to the position of the workbench corresponding to the limit plate; a sliding groove is opened in the middle of the fixed block; a sliding rod is slidably connected in the sliding groove, and the sliding rod has a bent structure; a screw rod is rotatably connected in the sliding groove; a handwheel is fixedly connected to the screw rod at a position corresponding to the outer side of the fixed block.

[0016] Preferably, a method for cutting to length for producing a distribution pipe for a new energy vehicle engine comprises the following steps:

[0017] S1: hoist or roll the distribution pipe body packed into a pipe bundle by steel belt to the workbench so that one of its edges contacts the rubber layer on the rotating roller;

[0018] S2: using the first motor to drive all the rollers to rotate synchronously, and using the forward and reverse rotation of the rollers to adjust the tube bundle formed by the multiple distribution tube bodies to the vicinity of the cutting line on the workbench;

[0019] S3: The position of the limit plate is adjusted by a hand wheel, and then the position of the tube bundle formed by the distribution tube body is finely adjusted by a roller, so that the end thereof abuts against the limit plate, and each roller contacts the corresponding steel belt;

[0020] S4: adjusting the position of each cutting machine so that the position of the cutting machine is aligned with the cutting line position between the guide plates;

[0021] S5: using each cutting machine to simultaneously cut the tube bundle formed by the distribution pipe body, thereby completing the rapid length-setting cutting of the distribution pipe body without disassembling the steel belt;

[0022] S6: Remove the distribution pipe body after the cut to length from the workbench.

[0023] Preferably, in the step S3, after the tube bundle formed by the distribution pipe body is fixed, the position of the cutting machine is adjusted to be located at the position of the cutting line, and then the distribution pipe bodies of different fixed lengths are cut therefrom.

[0024] Preferably, in the step S3, the second hinge block at the corresponding cutting line is driven downward by the telescopic cylinder, so that the roller located at the cutting line rotates at an angle of 4°-9°. After one end of the roller is deflected, the roller loses contact with the distribution tube body, so that the roller loses its support for the distribution tube body, and at this time there is a gap between the roller and the distribution tube body.

[0025] Preferably, in the step S6, the distribution pipe body is divided into multiple sections of tube bundles after cutting, and the telescopic cylinders at the corresponding tube bundle positions are adjusted so that the output ends of all the telescopic cylinders located there are moved downward, thereby driving the corresponding rollers to rotate. When the rotation angle of the rollers is greater than the inclination angle of the guide plate, the tube bundle of this section loses the support of all rollers and falls onto the guide plate. At this time, the tube bundle slides on the guide plate by its own gravity, and automatically falls onto the collection device on the side.

[0026] Beneficial effects of the present invention:

[0027] 1) When the distribution pipe body packed with steel belts is cut, the present invention directly uses a cutting machine in conjunction with a rotatable roller for cutting, without disassembling the distribution pipe body and cutting the distribution pipe body one by one. The present invention has the efficiency of large-scale cutting of the distribution pipe body, and is convenient and fast.

[0028] 2) The present invention can drive the second hinge block at the cutting line to move downward through the telescopic cylinder, so that the roller located there is rotated at an angle. After one end of the roller is deflected, the roller loses contact with the distribution tube body, and the roller can no longer support the distribution tube body. At this time, there is a gap between the roller and the distribution tube body. When the cutting machine cuts it, it will not accidentally touch it, thereby causing damage to the roller, which makes it easier for the cutting machine to cut the distribution tube body.

[0029] 3) The present invention utilizes a cutting machine to simultaneously cut the tube bundle formed by packaging multiple distribution pipe bodies, without the need to remove the steel belts thereon, which not only improves the cutting efficiency, but also saves the steps of repeatedly adjusting the positions of the distribution pipe bodies, further improving the cutting efficiency. In addition, after cutting, the steel belts can continue to tighten the cut distribution pipe bodies without the need for re-fixing, which not only saves resources but also improves the speed of the subsequent packaging and boxing process.

[0030] 4) The distribution pipe body in the present invention is divided into multiple sections of pipe bundles after cutting. At this time, the telescopic cylinders at the corresponding tube bundle positions are adjusted to move the output ends of all the telescopic cylinders at that location downward, thereby driving the corresponding rollers to rotate. When the rotation angle of the rollers is greater than the inclination angle of the guide plate, the tube bundle of this section loses the support of all rollers and falls onto the guide plate. At this time, the tube bundle slides on the guide plate by its own gravity and automatically falls onto the collection device on the side. This is fast and convenient, and improves the cutting efficiency of the distribution pipe body. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation mode of the present invention in the actual process is described in detail below:

[0051] When cutting the pipe bundle formed by tying the distribution pipe body 10 into a regular hexagon by using the steel band 11, the following steps are included:

[0052] S1: First, hoist or roll it onto the workbench 1 so that one of its edges contacts the rubber layer on the roller 5;

[0053] S2: The first driving gear 612 is driven to rotate by the first motor 614. The first driving gear 612 drives each transmission gear 6 to rotate through the first chain 613. The transmission gear 6 then drives all the rollers 5 to rotate synchronously. The tube bundle formed by the multiple distribution tube bodies 10 is adjusted to the approximate position on the workbench 1 by the forward and reverse rotation of the rollers 5.

[0054] S3: The screw rod 16 is rotated by the hand wheel 17, and the position of the limit plate 13 is adjusted by the cooperation of the screw rod 16, the slide groove 15 and the slide rod 14. Then, the position of the tube bundle formed by the distribution pipe body 10 is finely adjusted by the roller 5 again, so that the end of the tube bundle abuts against the limit plate 13, and each roller 5 is in contact with the corresponding steel belt 11, thereby completing the position adjustment of the distribution pipe body 10;

[0055] S4: adjusting the position of each cutting machine so that the position of the cutting machine is aligned with the position between the guide plates 9;

[0056] S5: using each cutting machine to simultaneously cut the tube bundle formed by the distribution pipe body 10, thereby completing the rapid length-setting cutting of the distribution pipe body 10 without disassembling the steel strip 11;

[0057] S6: removing the dispensing pipe body 10 from the workbench 1 after the cut-to-length process.

[0058] In step S1, it can be transferred to the workbench 1 using a gantry or transmission rollers and other equipment, and the position adjustment and loading and unloading of the tube bundle formed by the distribution pipe body 10 can be completed using the rollers 5 on the workbench 1. The rubber layer on the rollers 5 can be used to protect the distribution pipe body 10 and the steel belt 11 in contact to avoid local damage.

[0059] In step S2, after the tube bundle formed by the distribution pipe body 10 is placed on the roller 5, the roller 5 is rotated to drive it to shift, and the position of the steel belt 11 thereon is brought close to the corresponding roller 5, thereby completing the preliminary position adjustment of the tube bundle formed by the distribution pipe body 10, which is convenient for subsequent fixed-length cutting.

[0060] In step S3, since different vehicle models require different lengths of the distribution pipe body 10 (e.g. Figure 5 and Figure 8 As shown in the figure, the distribution pipe body 10 often needs to be cut into different lengths. In the scheme of the present invention, after the tube bundle formed by the distribution pipe body 10 is fixed, the position of the cutting machine (such as a reciprocating saw, a grinding wheel machine, a laser cutting machine) can be adjusted to the position of the cutting line, and then it can be cut. This is simple and convenient, and is easy to process distribution pipe bodies 10 of different specifications.

[0061] Among them, since the position of the roller 5 is a fixed interval and cannot be adjusted, if the required cutting line position is exactly at the position of the roller 5, it may cause the cutting machine to damage it. In the solution of the present invention, the second hinge block 4 at this location can be driven downward by the telescopic cylinder 7, so that the roller 5 located there is rotated at an angle, and the deflection angle can be set to about 4°-9°. After one end of the roller 5 is deflected, the roller 5 loses contact with the distribution pipe body 10, and the roller 5 can no longer support the distribution pipe body 10. At this time, there is a gap between the roller 5 and the distribution pipe body 10. When the cutting machine cuts it, it will not be accidentally touched, thereby causing damage to the roller 5, which is convenient for the cutting machine to cut the distribution pipe body 10.

[0062] Among them, after the roller 5 is deflected, the transmission gear 6 located there is also deflected accordingly. However, since the transmission gear 6 in this embodiment is meshed with the upper outer side of the first chain 613, the meshing effect can be directly lost after the deflection, and will not affect the rotation of other rollers 5, thereby avoiding affecting the cutting of the distribution tube body 10.

[0063] In step S3, if it is necessary to cut distribution pipe bodies 10 of different specifications, it is inconvenient to fix the position of the distribution pipe body 10. In the solution of the present invention, the screw rod 16 is rotated by using the hand wheel 17, and the screw rod 16 and the slide rod 14 cooperate with each other to adjust the initial position of the limit plate 13. By using the limit plate 13, the operator can easily limit the position of the tube bundle formed by the distribution pipe body 10, which is convenient for the later fixed-length cutting.

[0064] In step S5, since a cutting machine is used to simultaneously cut the tube bundle formed by packaging multiple distribution pipe bodies 10, there is no need to remove the steel belt 11 thereon, which not only improves the cutting efficiency, but also saves the repeated steps of adjusting the position of the distribution pipe body 10, further improving the cutting efficiency. In addition, after cutting, the steel belt 11 can continue to tighten the cut distribution pipe body 10 without the need for re-fixing, which not only saves resources but also improves the speed of the subsequent packaging and boxing process.

[0065] In step S6, the distribution pipe body 10 is divided into multiple sections of pipe bundles after cutting. At this time, the telescopic cylinders 7 at the corresponding tube bundle positions are adjusted to move the output ends of all the telescopic cylinders 7 located there downward, thereby driving the corresponding rollers 5 to rotate. When the rotation angle of the rollers 5 is greater than the inclination angle of the guide plate 9 (i.e., ∠A is greater than ∠B), the tube bundle of this section loses the support of all rollers 5 and falls onto the guide plate 9. At this time, the tube bundle slides on the guide plate 9 by its own gravity, and automatically falls onto the collection device on the side (such as: forklift and clamp, etc.), which is fast and convenient, thereby improving the cutting efficiency of the distribution pipe body 10.

[0066] Embodiment 2:

[0067] Please refer again Figure 7 As shown, the present invention is a fixed-length cutting device and method for producing engine distribution pipes of new energy vehicles. The structure of this embodiment is basically the same as that of the first embodiment, except that, in this embodiment, the transmission assembly includes a second chain 621 rotatably connected to each transmission gear 6, and the transmission gear 6 is meshed with the inner side of the second chain 621; the second chain 621 is rotatably connected to a second driving gear 622 corresponding to the position of the outermost transmission gear 6, and the second driving gear 622 is meshed with the second chain 621; a second motor 623 is fixedly arranged on the workbench 1, and the output end of the second motor 623 is connected to the second driving gear 622.

[0068] After the roller 5 is deflected, the transmission gear 6 located there is also deflected accordingly. However, since the transmission gear 6 in this embodiment is meshed with the inner side of the second chain 621, and the rotation angle of the roller 5 is relatively small, only 4°-9°, even if the angle of any one or more of the transmission gears 6 changes slightly, these transmission gears 6 can still mesh with the second chain 621, and will not affect the rotation of other transmission gears 6, thereby avoiding affecting the cutting of the distribution tube body 10.

[0069] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0070] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

A method for cutting to length for producing a distribution pipe for a new energy vehicle engine according to claim 7, characterized in that: In the step S3, the second hinge block (4) at the corresponding cutting line is driven downward by the telescopic cylinder (7), so that the roller (5) located at the cutting line is rotated at an angle of 4°-9°. After one end of the roller (5) is deflected, the roller (5) loses contact with the distribution pipe body (10), so that the roller (5) loses its bearing capacity on the distribution pipe body (10), and at this time, there is a gap between the roller (5) and the distribution pipe body (10).

10. A method for cutting to length for producing a distribution pipe for a new energy vehicle engine according to claim 7, characterized in that: In the step S6, the distribution pipe body (10) is divided into a plurality of pipe bundles after cutting. By adjusting the telescopic cylinders (7) at the positions corresponding to the pipe bundles, the output ends of all the telescopic cylinders (7) located at the positions are moved downward, thereby driving the corresponding rollers (5) to rotate. When the rotation angle of the rollers (5) is greater than the inclination angle of the guide plate (9), the pipe bundle of this section loses the support of all the rollers (5) and falls onto the guide plate (9). At this time, the pipe bundle slides on the guide plate (9) by its own gravity, thereby automatically falling onto the collection device on the side.
