Description

Technical Field

[0001] This utility model relates to the technical field of machining equipment, and in particular to a steel pipe feeding device. Background Technology

[0002] Steel pipes are a widely used basic raw material in modern hardware processing and furniture parts manufacturing. In the steel pipe production process, a whole steel pipe several meters long is first cut into steel pipe sections of specific lengths using cutting equipment. Then, these steel pipe sections undergo further processing such as bending, punching, and welding to finally produce the required parts or products.

[0003] In the aforementioned cutting process, most small and medium-sized processing plants currently use manual feeding. Specifically, one end of the steel pipe is manually lifted, painstakingly aligned, and inserted into the feed chute or support frame of the cutting machine. During the cutting process, the operator must continuously push the steel pipe forward to bring its end to the preset cutting position. After one section is cut, the operator continues pushing for the next cut, repeating this cycle until the entire steel pipe is cut.

[0004] However, operators need to stand at the loading station and transport the steel pipes to the cutting position at all times. The automation level is low, the labor intensity of operators is high, and the labor cost is high. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a steel pipe feeding device that can improve the automation level of the equipment, as well as reduce labor costs and labor intensity.

[0006] A steel pipe feeding device according to an embodiment of the present invention includes: a hopper having an inclined chute, the inclined chute having a storage area and a feeding area distributed along its inclined direction, the storage area and the feeding area being communicative, the storage area being used to accommodate multiple horizontally placed steel pipes, and the feeding area being used to accommodate one horizontally placed steel pipe; a blocking mechanism disposed between the storage area and the feeding area, the blocking mechanism being able to intermittently block the steel pipes in the storage area while allowing one steel pipe in the storage area to pass through; a positioning mechanism including a positioning member, a clamping member, and a first cylinder for driving the clamping member to move horizontally, the positioning member being fixedly disposed on the side of the feeding area away from the storage area, the clamping member being able to move closer to the positioning member to clamp the radial outer surface of the positioned steel pipe; and a pushing mechanism for pushing the steel pipe to a cutting position.

[0007] A steel pipe feeding device according to an embodiment of the present utility model has at least the following beneficial effects: 1. This utility model sets up a hopper with an inclined chute, which can store multiple steel pipes at once. The steel pipes automatically slide to the loading area by gravity, so that a large number of steel pipes can be put into the storage area of ​​the inclined chute within a certain period of time, which facilitates the continuous supply of steel pipes to the cutting mechanism of the subsequent process.

[0008] 2. This utility model, by setting up a blocking mechanism, achieves the separation of densely stacked steel pipes through the intermittent action of the blocking mechanism, and releases the steel pipes from the storage area to the loading area in an orderly manner, one at a time, providing a basis for subsequent accurate positioning and pushing actions, and eliminating the need for manual handling of the steel pipes to the loading area.

[0009] 3. This utility model, by setting up a positioning component, a clamping component, and a first cylinder, enables the clamping component to move horizontally. The positioning component and the clamping component can clamp and correct the position of the steel pipe from the radial outer surface, effectively preventing the steel pipe from rolling or shifting during the pushing process. Furthermore, by setting up a pushing mechanism, the pushing mechanism can push the steel pipe to the cutting position without the need for manual pushing of the steel pipe to the cutting position, ensuring the fixed length accuracy and cross-sectional quality of each cut, solving the problem of unstable manual pushing, reducing labor costs and labor intensity.

The two second blocking components clamp the two ends of the steel pipe at the bottom of the vertical plate. Each second blocking component includes an abutting rod and a third cylinder that drives the abutting rod to move horizontally. When the baffle blocks the steel pipe in the storage area, the abutting rod is used to abut the end of the steel pipe to prevent the steel pipe from sliding down into the feeding area.

[0013] According to an embodiment of the present utility model, a steel pipe feeding device is provided at the end of the abutment rod, and the positioning pin can match and position with the inside of the steel pipe.

[0027] A steel pipe feeding device according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0028] Reference Figure 1 The present invention aims to provide an embodiment of a steel pipe feeding device.

[0029] A steel pipe 140 feeding device according to an embodiment of the present invention includes a hopper 100, a blocking mechanism, a positioning mechanism, and a pushing mechanism. The hopper 100 is provided with an inclined chute 110, which has a storage area 120 and a feeding area 130 distributed along its inclined direction. The storage area 120 and the feeding area 130 are communicative. The storage area 120 is used to accommodate multiple horizontally placed steel pipes 140, and the feeding area 130 is used to accommodate one horizontally placed steel pipe 140. The blocking mechanism is provided in the storage area 120 and the feeding area 130. Between, the blocking mechanism can intermittently block the steel pipe 140 in the storage area 120 and allow one steel pipe 140 in the storage area 120 to pass through; the positioning mechanism includes a positioning member 150, a clamping member 160, and a first cylinder 170 that drives the clamping member 160 to move horizontally. The positioning member 150 is fixedly set on the side of the feeding area 130 away from the storage area 120, and the clamping member 160 can move close to the positioning member 150 to clamp the radial outer surface of the positioning steel pipe 140; the pushing mechanism is used to push the steel pipe 140 to the cutting position.

[0030] This utility model sets up a hopper 100 with an inclined chute 110. The inclined chute 110 can store multiple steel pipes 140 at one time. The steel pipes 140 automatically slide to the loading area 130 by gravity. Thus, a large number of steel pipes 140 can be put into the storage area 120 of the inclined chute 110 within a certain period of time, which facilitates the continuous supply of steel pipes 140 to the cutting mechanism of the subsequent process.

[0031] Furthermore, by setting up a blocking mechanism, the present invention achieves the separation of densely stacked steel pipes 140 through the intermittent action of the blocking mechanism, and releases the steel pipes 140 from the storage area 120 to the loading area 130 in an orderly manner and one at a time, providing a basis for subsequent accurate positioning and pushing actions, and eliminating the need for manual handling of the steel pipes 140 to the loading area 130.

[0032] Furthermore, by setting up a positioning component 150, a clamping component 160, and a first cylinder 170, this utility model can drive the clamping component 160 to move horizontally. The positioning component 150 and the clamping component 160 can clamp and correct the position of the steel pipe 140 from the radial outer surface, effectively preventing the steel pipe 140 from rolling or shifting during the pushing process. In addition, by setting up a pushing mechanism, the pushing mechanism can push the steel pipe 140 to the cutting position without the need for manual pushing of the steel pipe 140 to the cutting position, ensuring the fixed length accuracy and cross-sectional quality of each cut, solving the problem of unstable manual pushing, reducing labor costs and labor intensity.

[0033] In some embodiments of this utility model, reference is made to Figure 2 and Figure 3The blocking mechanism includes a first blocking component, which includes a baffle 180 and a second cylinder 190 that drives the baffle 180 to rise and fall. When the baffle 180 falls, it can prevent the steel pipe 140 from sliding from the storage area 120 to the loading area 130. When the baffle 180 rises, it allows a steel pipe 140 to slide from the storage area 120 to the loading area 130.

[0034] The second cylinder 190 drives the baffle 180 to perform simple lifting and lowering movements. The mechanical structure is simple, the manufacturing cost is low, the failure rate is low, and it is easy to maintain.

[0035] The lifting and lowering action of the baffle 180 can be precisely controlled by the control system to ensure that only one steel pipe 140 is released at a time. The action is clear and reliable, avoiding jamming or chaos caused by multiple steel pipes 140 entering the feeding area 130 at the same time.

[0036] In some embodiments of this utility model, reference is made to Figure 2 and Figure 3 The storage area 120 is provided with a vertical plate 220 on the side near the first blocking component. A steel pipe 140 is allowed to pass through the bottom of the vertical plate 220, and a steel pipe 140 is accommodated between the vertical plate 220 and the baffle 180.

[0037] One side of the upright plate 220 forms a precise accommodating space with the baffle 180, ensuring that only one steel pipe 140 is accommodated at a time. The other side of the upright plate 220 can isolate stacked steel pipes 140, and the bottom of the upright plate 220 allows one steel pipe 140 to pass through.

[0038] In some embodiments of this utility model, reference is made to Figure 1 The blocking mechanism includes two second blocking components. The two second blocking components clamp the two ends of the steel pipe 140 at the bottom of the upright plate 220. The second blocking component includes an abutment rod 200 and a third cylinder 210 that drives the abutment rod 200 to move horizontally. When the baffle 180 blocks the steel pipe 140 in the storage area 120, the abutment rod 200 is used to abut the end of the steel pipe 140 to prevent the steel pipe 140 from sliding down into the feeding area 130.

[0039] For the steel pipe 140 that is already at the bottom of the vertical plate 220 and is about to be released, it is abutted from both ends by two second blocking components. The abutment rod 200 can completely lock its position. After the baffle 180 is raised, only one steel pipe 140 is allowed to slide into the feeding area 130, ensuring the controllability of the number of steel pipes fed.

[0040] In some embodiments of this utility model, the end of the abutment rod 200 is provided with a positioning pin 230, which can be matched and positioned with the inside of the steel pipe 140.

[0041] The positioning pin 230 is inserted into the steel pipe 140 for positioning. Positioning from the inside completely eliminates the possibility of the steel pipe 140 rolling, making the clamping more stable.

[0042] In some embodiments of this utility model, the positioning element 150 and the clamping element are both rollers, and multiple rollers are provided, which are distributed along the length direction of the steel pipe 140.

[0043] By using rollers as positioning elements 150 and clamping elements 160, sliding friction is transformed into rolling friction, which greatly reduces the scratches and wear on the surface of the steel pipe 140 during clamping and pushing. Furthermore, it facilitates smooth subsequent pushing actions and reduces the load on the drive mechanism.

[0044] In some embodiments of this utility model, the pushing mechanism includes a push rod 240 and a fourth cylinder 250 that drives the push rod 240 to move horizontally. The push rod 240 is used to push the end of the steel pipe 140 on the positioning mechanism.

[0045] The fourth cylinder 250 is used as the power source to push the push rod 240. Its movement is smooth and can realize the smooth, linear and controllable pushing of the steel pipe 140, ensuring that the steel pipe 140 accurately reaches the preset cutting position.

[0046] In addition, the cylinder push rod 240 mechanism has a simple structure, fast response speed, and convenient maintenance, making it very suitable for this kind of short-stroke, repetitive pushing operation.

[0047] In some embodiments of this utility model, a conveying mechanism is provided on the side of the feeding area 130 away from the pushing mechanism. The conveying mechanism includes a first conveying wheel 260, a second conveying wheel 270, and a motor 280 that drives the first conveying wheel 260 to rotate. The first conveying wheel 260 and the second conveying wheel 270 can clamp the conveying steel pipe 140.

[0048] After the feeding mechanism completes the feeding, the first conveyor wheel 260 and the second conveyor wheel 270 actively convey the steel pipe 140 into the cutting machine, providing a more continuous and powerful conveying force, and eliminating the need for manual pushing of the steel pipe 140 to the cutting position.

[0049] In some embodiments of this utility model, the conveying mechanism further includes a translation frame 290, a fifth cylinder 300 that drives the translation frame 290 to move horizontally, and a second conveying wheel 270 mounted on the translation frame 290. The second conveying wheel 270 can move closer to or further away from the first conveying wheel 260.

[0050] The translation frame 290 is driven by the fifth cylinder 300, which allows the second conveying wheel 270 to actively move closer to or further away from the first conveying wheel 260. The controllable cylinder can provide a stable and sufficient clamping force to prevent the steel pipe 140 from slipping during the conveying process and ensure the accuracy of the feeding length.

[0051] In some embodiments of this utility model, a photoelectric sensor 310 is provided on the side of the conveying mechanism near the feeding area 130. The photoelectric sensor 310 is used to detect the steel pipe 140.

[0052] The photoelectric sensor 310 is used to detect whether the steel pipe 140 is in place in the feeding area 130. It feeds back the detection signal to the control system, and the conveying mechanism can clamp and convey the steel pipe 140.

[0053] In the description of this specification, references to terms such as "an embodiment," "some embodiments," "illustrative embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention.
