A pipe chamfering machine

Abstract

The present invention discloses a pipe chamfering machine, belonging to the field of pipe fitting processing. By using a chain-mounted drill bit, which serves as a locator to clamp the material and, when the drill bit contacts the driving device, the driving device pushes the drill bit to rotate. At the same time, the clamping device contacts the material, and at this time, the material is pressed tightly and cannot rotate. The rotation of the drill bit enables the chamfering tool on the drill bit to cut the material, thereby achieving the chamfering effect. After chamfering is completed, by using the guiding groove of the chamfering device, the drill bit contracts, and then the drill bit no longer clamps the material, enabling the material to be thrown out along the discharge port, realizing the chamfering of the material. Since the drill bits distributed in a chain can perform a flow operation one by one, the efficiency is greatly improved.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 shown, a pipe chamfering machine includes:

[0031] The fuselage 1, which is the base of the chamfering machine, and the fuselage 1 is placed on the ground;

[0032] The feed inlet 4, which is installed on the fuselage 1, and the feed inlet 4 is used to place the material to be processed;

[0033] The chamfering device 2, which is installed on the fuselage 1, and the chamfering device 2 includes a plurality of drill bits 22 and is distributed in a chain-like manner. The chamfering device 2 is used to position the material in the feed inlet 4 and drive the material into the processing area for chamfering work;

[0034] The clamping device 5 is installed on the fuselage 1. The clamping device 5 is used to perform a pressing action on the material entering the processing area to prevent the material from rotating;

[0035] The driving device 3 is installed on the chamfering device 2. The driving device 3 is a motor for driving the drill bit 22 to rotate;

[0036] The discharge port is located at the lowermost end in the vertical direction of the chamfering device 2. The discharge port is used to pour out the processed material.

[0037] Among them, the chamfering device 2 includes a driving chain 23, a sliding sleeve 24 and a guiding groove 21. The driving chain 23 is distributed along the feed port 4, the processing area, the discharge port and the feed port 4. There are two driving chains 23. The sliding sleeve 24 includes two semi-circles that can be combined with each other to form a ring structure. The drill bit 22 slides within the sliding sleeve 24. One end of the drill bit 22 slides within the guiding groove 21, and the other end abuts against the material. The guiding groove 21 includes a processing section 212, a reset section 213, a transmission section 214 and a clamping section 211 that are connected in sequence. The depth of the clamping section 211 decreases from the transmission section 214 to the processing section 212. The depth of the reset section 213 increases from the processing section 212 to the transmission section 214. The depth of the processing section 212 decreases from the clamping section 211 to the reset section 213. The end of the drill bit 22 that penetrates into the guiding groove 21 slides within the guiding groove 21 through a bearing 223. Protrusions 215 for pushing the drill bit 22 in the depth direction are provided at the reset section 213 and the transmission section 214. The protrusions 215 can abut against the bearing 223.

[0038] When this product is in use, materials are stacked along the feed inlet 4. The materials fall to the bottom under the influence of gravity. When the driving chain 23 drives the drill bit 22 to move to the bottom of the feed inlet 4, the drill bit 22 receives the thrust of the guide groove 21 and is pushed towards the materials, so that one end of the drill bit 22 penetrates into the interior of the materials. And because the drill bit 22 is driven by the driving chain 23, the drill bit 22 pulls the materials out of the feed inlet 4. When the materials are pulled to the processing area, at this time, the clamping device 5 contacts the materials. Through the frictional force generated between the clamping device 5 and the materials, the materials are clamped. At the same time, the drill bit 22 contacts the driving device 3, causing the drill bit 22 to rotate. At the same time, the drill bit 22 receives the thrust of the guide groove 21, making the drill bit 22 move closer to the materials, so as to chamfer the materials with the drill bit 22. When the drill bit 22 drives the materials through the processing area, the chamfering of the materials is completed. At this time, the bearing 223 on the drill bit 22 is guided by the protrusion 215 on the reset section 213, so as to move in the depth direction of the guide groove 21, and then the drill bit 22 is separated from the materials. After the drill bit 22 is separated from the materials, the materials fall along the discharge port under the influence of gravity, realizing the feeding, processing and discharging process of one material. After the drill bit 22 completes the above operation once, it is pulled back to the bottom of the feed inlet 4 along the transmission groove by the driving chain 23 for processing the next material. Since several drill bits 22 are distributed along the driving chain 23, the materials are continuously pulled out of the feed inlet 4 and processed and discharged. The whole process involves manual participation, achieving the purpose of efficient production.

[0039] The chamfering device 2 includes a driving chain 23, a sliding sleeve 24 and a guide groove 21. The driving chain 23 is distributed along the feed inlet 4, the processing area, the discharge port and the feed inlet 4. There are two driving chains 23. The sliding sleeve 24 includes two semi - circles that can be combined with each other to form a ring structure. The drill bit 22 slides within the sliding sleeve 24. One end of the drill bit 22 slides within the guide groove 21, and the other end abuts against the materials. By setting like this, the drill bit 22 can continuously move driven by the driving chain 23. And the pushing of the drill bit 22 by the guide groove 21 is the key point of this product. Its setting enables the drill bit 22 to automatically complete the operations of material positioning, clamping, cutting and discharging. The setting of the sliding sleeve 24 enables the drill bit 22 to be replaced in time after wear. Just open the two semi - circles, and the drill bit 22 can be taken out and replaced.

[0040] The guiding groove 21 includes a processing section 212, a reset section 213, a transmission section 214, and a clamping section 211 that are connected in sequence. The depth of the clamping section 211 decreases from the transmission section 214 to the processing section 212. This setting enables the drill bit 22 to receive the thrust generated when the depth of the clamping section 211 decreases, thereby pushing the drill bit 22 out, and then enabling the drill bit 22 to penetrate into the material to achieve clamping and positioning of the material. The depth of the reset section 213 increases from the processing section 212 to the transmission section 214. This setting is used to release the processed material, enabling the material to achieve the effect of automatic unloading after processing. The depth of the processing section 212 decreases from the clamping section 211 to the reset section 213. This setting is used to push the cutting amount of the drill bit 22 according to the material of the material when cutting the material, thereby making the chamfer cutting of the material smoother.

[0041] One end of the drill bit 22 that penetrates into the guiding groove 21 slides in the guiding groove 21 through a bearing 223. Protrusions 215 for pushing the drill bit 22 to move in the depth direction are provided at the reset section 213 and the transmission section 214. The protrusions 215 can abut against the bearing 223. The setting of the bearing 223 enables the drill bit 22 not to generate excessive friction with the guiding groove 21 when rotating, thereby protecting the guiding groove 21. The setting of the protrusions 215 enables the drill bit 22 to quickly retract into the guiding groove 21 under the guidance of the protrusions 215 after cutting, thereby realizing the unloading operation of the material.

[0042] The drill bit 22 includes a positioning area 221 for positioning the middle part of the material and a chamfering tool 222 protruding from the surface of the drill bit 22 for cutting. The inclined surface on the positioning area 221 enables the drill bit 22 to accurately insert into the middle part of the material when contacting the material and push the material to slide along the inclined surface until it coincides with the axis of the drill bit 22, achieving more accurate positioning. The setting of the chamfering tool 222 enables the chamfering tool 222 to cut the required processing position after the positioning area 221 completes positioning.

[0043] The driving device 3 includes two power motors 31. The two power motors 31 move synchronously through a toothed chain 32. Teeth 224 that can mesh with the toothed chain 32 are provided in the middle of the drill bit 22. The transmission of the toothed chain 32 is more stable, enabling the drill bit 22 to have stronger cutting force, and the transmission and separation of the toothed chain 32 are easier to control.

[0044] A magnet 1 is provided at the top of the teeth 224. Magnets 2 are provided on both sides of the groove of the toothed chain 32, and a magnet 3 is provided in the groove. The magnet 1 and the magnet 2 repel each other, and the magnet 3 attracts the magnet 1. Due to the influence of magnetism, the state where the top of the teeth 224 abuts against both sides of the groove of the toothed chain 32 and causes the equipment to jam will not occur.

[0045] The driving device 3 and the chamfering device 2 are symmetrically arranged in two groups along the machine body 1, so that double-head processing can be performed simultaneously. The machine body 1 is provided with a cylinder 6 for pushing one group of the driving devices 3 to move, so that materials of different lengths can be processed.

[0046] The clamping device 5 includes an abutment belt located below the material movement path and a moving belt located above the material movement path. The moving belt is connected to the rotating motor through a transmission, and the rotating motor is connected to the machine body through a telescopic cylinder. The moving belt can be moved to abut against the material. An anti-slip rubber pad is provided on the moving belt for abutting and positioning with the material.

[0047] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0048] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
