Description

Technical Field

[0001] This utility model relates to the field of pipe fitting processing equipment, and in particular to a tail material cutting, chamfering and shaping equipment. Background Technology

[0002] Connecting pipes for automobiles or air conditioning systems typically require double-ended forming and further bending to ensure proper pipe connections between different components within the vehicle or air conditioning system. Current processing techniques generally involve first processing one end of the pipe, then bending it, and finally removing excess material, chamfering, shaping, or upsetting the other end.

[0003] However, the cutting, chamfering, and shaping processes in the existing manufacturing process require different equipment, which makes it impossible to guarantee the tolerance of multiple clamping operations between different equipment, and the efficiency is very low. Utility Model Content

[0004] The purpose of this invention is to provide a tail material cutting, chamfering and shaping device that improves the efficiency of double-head forming of pipelines and effectively avoids errors caused by transfer between multiple devices.

[0005] To solve the above-mentioned technical problems, this utility model provides a tail material cutting, chamfering and shaping device, including a worktable, a clamping mold disposed on the side of the worktable, and a shifting plate movably disposed on the worktable. The shifting plate is sequentially disposed of a cutting component, a chamfering component and a shaping component, so that the shifting plate drives the cutting component, the chamfering component and the shaping component to move sequentially to the corresponding positions of the clamping mold. The chamfering component includes a chamfering seat movably disposed on the shifting plate and a chamfering assembly rotatably disposed on the chamfering seat. At least three chamfering cutters are arranged circumferentially on the side of the chamfering assembly near the clamping mold, and the at least three chamfering cutters correspond to the outer wall, inner wall and end face of the pipe end respectively, so that a chamfering processing position is formed between the at least three chamfering cutters.

[0006] Furthermore, the chamfering component also includes a positioning plate disposed on the side of the chamfering seat, the positioning plate being positioned toward the clamping mold.

[0007] Furthermore, the chamfering component also includes a protective cover covering the outside of the chamfering assembly, wherein the surface of the protective cover near the clamping mold is flush with the surface of the positioning plate near the clamping mold.

[0008] Furthermore, several elastic elements are connected between the protective cover and the chamfered seat.

[0009] Furthermore, the cutting component includes a cutting seat movably mounted on the shift plate and a cutting blade rotatably mounted on one side of the cutting seat. The cutting blade is covered with a cover, and a through groove is provided on the side of the cover so that the pipe can contact the cutting blade through the through groove.

[0010] Furthermore, the shaping component includes a plurality of stamping seats movably disposed on the shift plate, wherein the stamping seats have a punch at the end near the clamping die.

[0011] Furthermore, a chip hopper is provided at the workbench. The chip hopper is located between the shifting plate and the clamping mold and is located on the lower side of the clamping mold. The chip hopper has a guide slope inside. An opening matching the guide slope is opened at the bottom of the chip hopper. A chip guide hopper is inclinedly arranged at the opening, and a material receiving groove is connected to the lower part of the chip guide hopper.

[0012] Furthermore, the chip guide hopper is provided with several through holes, and an oil receiving hopper corresponding to the through holes is provided on the lower side of the chip guide hopper.

[0013] Furthermore, a baffle is installed inside the receiving trough, and the baffle has a porous structure.

[0014] The beneficial effects of this utility model are as follows: the pipe to be processed is placed in the clamping mold for clamping and fixing, and then the shifting plate drives each component to move, so that the processing components corresponding to each process can be directly moved to the corresponding position of the clamping mold without the need for the pipe to be moved and re-clamped. This can effectively avoid the error problem caused by multiple clamping of the pipe. Moreover, since the pipe does not need to be transferred between multiple devices, the processing efficiency of the pipe is improved.

[0015] When chamfering the pipe end of the fitting using the chamfering component, the chamfering seat is first moved to the pipe end position with the shift plate. Then, the chamfering seat moves closer to the pipe end, so that the chamfering assembly is close to the position to be processed on the pipe end. At this time, the chamfering assembly drives the three chamfering cutters to rotate and cut, and the outer wall, inner wall and end face of the pipe end are chamfered by the three chamfering cutters respectively, which can effectively increase the chamfering processing efficiency of each side of the pipe end.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0030] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0031] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0032] like Figures 1-12 The present invention provides a tail material cutting, chamfering and shaping device, including a worktable 1, a clamping mold 2 disposed on the side of the worktable 1, and a shifting plate 3 movably disposed on the worktable 1. The shifting plate 3 is sequentially provided with a cutting component, a chamfering component and a shaping component, so that the shifting plate 3 drives the cutting component, the chamfering component and the shaping component to move sequentially to the corresponding positions of the clamping mold 2. The chamfering component includes a chamfering seat 4 movably disposed on the shifting plate 3 and a chamfering assembly 5 rotatably disposed on the chamfering seat 4. The chamfering assembly 5 is provided with at least three chamfering cutters 6 circumferentially arranged on the side of the clamping mold 2, and the at least three chamfering cutters 6 correspond to the outer wall, the inner wall and the end face of the pipe end respectively, so that a chamfering processing position is formed between the at least three chamfering cutters 6.

[0033] The pipe fitting to be processed is placed in the clamping mold and clamped and fixed. Then, the shifting plate drives each component to move, so that the processing component corresponding to each process can be directly moved to the corresponding position of the clamping mold without moving or re-clamping the pipe fitting. This can effectively avoid the error problem caused by multiple clamping of the pipe fitting. Moreover, since the pipe fitting does not need to be transferred between multiple devices, the processing efficiency of the pipe fitting is improved.

[0034] When chamfering the pipe end of the fitting using the chamfering component, the chamfering seat is first moved to the pipe end position with the shift plate. Then, the chamfering seat moves closer to the pipe end, so that the chamfering assembly is close to the position to be processed on the pipe end. At this time, the chamfering assembly drives the three chamfering cutters to rotate and cut, and the outer wall, inner wall and end face of the pipe end are chamfered by the three chamfering cutters respectively, which can effectively increase the chamfering processing efficiency of each side of the pipe end.

[0035] In one embodiment of this solution, the clamping mold includes at least two clamping blocks that are arranged to move relative to each other, and different conforming clamping molds can be selected according to the structure of different pipes after bending, so as to ensure that the clamping mold holds the pipes stably.

[0036] In another embodiment of this solution, a guide rail matching the shifting plate is provided on the worktable. The shifting plate is controlled to move and shift along the guide rail by a servo motor and a lead screw drive. A guide rail matching the chamfering seat is provided on the shifting plate. The chamfering seat is controlled to move along the guide rail by a servo motor and a lead screw drive, thereby moving the chamfering seat closer to or away from the clamping mold position. A motor is installed inside the chamfering seat. The motor controls the rotation of the chamfering assembly, thereby driving each chamfering blade to rotate and cut. The chamfering blade and the chamfering assembly can be detachably connected by bolts, so that the chamfering blade can be disassembled, replaced, and its installation position adjusted.

[0037] It is worth mentioning that this solution is mainly for pipe fittings that have undergone bending, and further processing of both ends of the pipe. It can be used in the following steps: clamping and fixing, cutting off the excess material with the cutting component, chamfering with the chamfering component, shaping the end of the shaping component, and unloading the material.

[0038] Preferably, the chamfering component further includes a positioning plate 7 disposed on the side of the chamfering seat 4, the positioning plate 7 being positioned toward the clamping mold 2.

[0039] Specifically, when chamfering the pipe end, the positioning plate is first moved to the corresponding position on the pipe end, and then the chamfering seat moves closer to the pipe end, so that the pipe end is positioned against the positioning plate. Then the chamfering seat is translated so that the pipe end moves to the chamfering assembly, and the stroke of the chamfering amount can be accurately positioned.

[0040] A pressure sensor can be installed at the positioning plate so that when the pipe end touches the positioning plate, the position of the pipe end can be sensed by the pressure sensor.

[0041] Preferably, the chamfering component further includes a protective cover 8 covering the outside of the chamfering assembly 5, wherein the surface of the protective cover 8 near the clamping mold 2 is flush with the surface of the positioning plate 7 near the clamping mold 2.

[0042] Specifically, with the above settings, since the surface of the protective cover near the clamping mold is flush with the surface of the positioning plate near the clamping mold, the positioning plate moves the chamfering seat after it comes into contact with the tube end, thereby determining the distance between the tube end and the chamfering assembly. The tube end will not interfere with the protective cover, and the protective cover can protect and collect the flying chips generated during the chamfering process.

[0043] Preferably, a plurality of elastic elements 9 are connected between the protective cover 8 and the chamfer seat 4, so that when the tube end and the protective cover move closer to each other, even if the tube end collides with the protective cover, the protective cover can shake to a certain extent under the elastic force of the elastic elements, thereby avoiding damage to the tube end caused by hard contact; wherein, the elastic elements can be spring structures.

[0044] Preferably, the cutting component includes a cutting seat 10 movably disposed on the switching plate 3 and a cutting blade 11 rotatably disposed on one side of the cutting seat 10. The cutting blade 11 is covered by a cover body 12, and a through groove 13 is provided on the side of the cover body 12 so that the pipe can contact the cutting blade 11 through the through groove 13.

[0045] Specifically, when it is necessary to cut off the excess material at the pipe end, the shift plate moves the cutting seat to the side of the pipe end, and then the cutting blade rotates relative to the cutting seat to cut. At the same time, the shift plate continues to move the cutting seat closer to the pipe end, so that the cutting blade cuts off the excess material at the pipe end during the rotation process. The shrapnel generated during the cutting process can be protected and collected by the cover.

[0046] The shift plate is equipped with a guide rail that matches the cutting seat. The cutting seat is moved along the guide rail by a cylinder, which in turn controls the cutting blade to move closer to or further away from the pipe end to adjust the cutting position. The cutting seat has a motor inside, which, together with a reducer, controls the rotation of the cutting blade for cutting.

[0047] It is worth mentioning that the cutting blade is a saw blade. The advantage of setting up the sawing method in this solution to cut the pipe from one side is that for some irregular pipes, after the pipe is bent, the rear end of the pipe faces the inside of the equipment. If a conventional cutting method (such as axial feed cutting) is used, it is easy to cause interference between the cutting mechanism and the end of the pipe facing the inside of the equipment. The sawing method of cutting from the side of the pipe can avoid the above interference.

[0048] Preferably, the shaping component includes a plurality of stamping seats 14 movably disposed on the shift plate 3, and the stamping seat 14 has a punch 15 at one end near the clamping die 2.

[0049] Specifically, during the stamping and shaping process of the pipe end, the shift plate moves the corresponding stamping seat to the pipe end position, and then the stamping seat drives the punch to perform stamping and shaping on the pipe end to increase the stability of the pipe end processing.

[0050] The shift plate is equipped with a guide rail that matches the stamping seat. The stamping seat is moved along the guide rail by the hydraulic cylinder to stamp, so that the punch can be controlled by the hydraulic cylinder to stamp. The specific punch style can be selected and changed according to the specific processing requirements.

[0051] Preferably, a chip hopper 16 is provided at the workbench 1. The chip hopper 16 is located between the shift plate 3 and the clamping mold 2 and is located on the lower side of the clamping mold 2. The chip hopper 16 has a guide slope 17 inside. The bottom of the chip hopper 16 has an opening that matches the guide slope 17. A chip guide hopper 18 is inclinedly provided at the opening, and a material receiving groove 19 is connected to the lower part of the chip guide hopper 18.

[0052] Specifically, the flying debris generated during cutting and chamfering can be collected in a chip hopper. The debris slides down the guide ramp to the opening and then into the chip hopper. It continues to slide down the chip hopper into the material collection trough for unified collection and subsequent centralized processing.

[0053] Preferably, the chip guide hopper 18 is provided with a plurality of through holes 20, and an oil receiving hopper 21 corresponding to the through holes 20 is provided on the lower side of the chip guide hopper 18.

[0054] Specifically, as the waste chips slide down the chip guide hopper, several through holes are used to collect the cooling oil and other oils carried in the waste chips, allowing the oil to drip down into the oil receiving hopper for separation and collection.

[0055] Preferably, a baffle 22 is installed inside the receiving trough 19, and the baffle 22 has a porous structure.

[0056] Specifically, after the waste debris finally falls to the baffle, the oil remaining in the waste debris is further separated and collected through the porous structure.

[0057] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
