Description

Technical Field

[0001] The invention relates to the technical field of pipe fitting processing, and in particular to an automatic feeding mechanism for processing stainless steel pipe fittings. Background Art

[0002] In modern industrial production, the processing efficiency and precision of stainless steel pipe fittings play a decisive role in the smoothness of the entire production process. With the continuous development of the manufacturing industry, the requirements for the processing quality and production efficiency of stainless steel pipe fittings are also increasing. The traditional manual feeding method is not only labor-intensive, but also prone to fatigue and errors during long-term continuous operation, which directly affects production efficiency and product quality.

[0003] In response to the above technical problems, the applicant has retrieved some existing technologies to realize the self-feeding of pipe fittings. For example, the patent publication number is CN116588639A, and its main technical means is that the steel pipe fittings slide to the discharge port through the bottom inclined surface of the aggregate frame and discharge downward. The first steel pipe fittings discharged fall on the upper end of the receiving plate and align with the discharge port, and then the steel pipe fittings discharged are stacked in sequence. The two groups of steel pipe fittings at the bottom are respectively limited by push blocks and plug rods. As the abutment piece 1 and the placement plate continue to push, the steel pipe fittings at the bottom are pushed out of the lower end of the aggregate frame and move to the positioning piece. As the steel pipe fittings at the bottom are pushed out, the steel pipe fittings on the upper layer are automatically positioned to the bottom, thereby realizing intermittent discharge and reducing collision damage between steel pipe fittings and blockage of the discharge port.

[0004] However, after analysis by the applicant, the disadvantage of this technical solution is that since the steel pipes are stacked at the lower end of the aggregate frame, the steel pipe fittings on the bottom layer will move under the continuous push of the abutment plate and the storage plate, which will cause the moving steel pipe fittings to produce friction with the steel pipe fittings stacked above them, and the moving direction is along the length direction of the pipe fittings, which will cause greater friction, which will not only cause friction damage to the surface of the steel pipe fittings, but also produce a large abnormal noise, and the upper steel pipe fittings will automatically move to the bottom, then it is necessary to wait for the abutment plate and the storage plate to return to their original positions, at which time the upper steel pipe fittings will fall, and the first pipe fitting that hits the lower end of the aggregate frame will stop immediately, and the second pipe fitting will hit the first pipe fitting, and so on. The problem of mutual collision between the two adjacent pipe fittings will still occur, and there is still the problem of collision damage. Based on this, the present invention purposely provides an automatic feeding mechanism for stainless steel pipe fittings processing that can completely avoid damage caused by mutual collision of materials during the feeding process.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 8 As shown, the present invention is an automatic feeding mechanism for stainless steel pipe processing, comprising:

[0033] A feeding frame 1 is provided with a driving component and a linkage component, and a plurality of storage slots 12 arranged at equal intervals are symmetrically provided on both sides thereof, each of the storage slots 12 is rotatably connected to a rotating plate 5, and the driving component drives the rotating plate 5 to perform reciprocating rotational motion through the linkage component, a telescopic block 6 is provided between two adjacent storage slots 12, and a plurality of telescopic blocks 6 are arranged at equal intervals, the telescopic block 6 is slidably connected to the feeding frame 1, and is driven by the driving component to perform reciprocating translational motion, a feed port 101 is provided at the top of the feeding frame 1, and a discharge port 102 is provided at the bottom, the feed port 101 is connected to the feeding component, a plurality of stainless steel tubes 3 are provided in the feeding frame 1, and there is a gap between two adjacent stainless steel tubes 3, and the number of the stainless steel tubes 3 in the feeding frame 1 is constant;

[0034] When the driving component drives the telescopic block 6 to extend, the driving component drives the rotating plate 5 to rotate into the receiving groove 12 through the linkage component, and the inner walls at both ends of each stainless steel tube 3 slide down along the plate surfaces of the two rotating plates 5 respectively until the telescopic block 6 is fully extended, and the rotating plate 5 rotates into the receiving groove 12, and the inner walls at both ends of each stainless steel tube 3 slide down from the plate surfaces of the two rotating plates 5 to the telescopic block 6 respectively, and the lowest stainless steel tube 3 falls onto the discharge port 102; when the driving component drives the telescopic block 6 to contract, the driving component drives the rotating plate 5 to gradually rotate away from the receiving groove 12 through the linkage component until the telescopic block 6 is fully contracted, and the inner walls at both ends of each stainless steel tube 3 slide down from the telescopic block 6 to the rotating plate 5 respectively, and the maximum height difference of the movement trajectory of the rotating plate 5 and the telescopic block 6 is less than the diameter of the stainless steel tube 3.

[0035] In practical application, this embodiment is based on Figure 4 As shown, this is the initial state of all the stainless steel tubes 3 in the feeding frame 1. In this state, the telescopic block 6 is completely retracted, and the rotating plate 5 is completely rotated away from the receiving groove 12. Both ends of each stainless steel tube 3 include a rotating plate 5 and a telescopic block 6, except that both ends of the lowest stainless steel tube 3 include only one rotating plate 5, and one end of the rotating plate 5 abuts against the inner wall of the stainless steel tube 3, and there is a gap between two adjacent stainless steel tubes 3; when feeding is required, the telescopic block 6 is controlled to extend by the driving component. At this time, the driving component drives the rotating plate 5 to rotate into the receiving groove 12 through the linkage component. As the rotating plate 5 rotates, the inner walls of the two ends of the stainless steel tube 3 will gradually slide down along the plate surface of the rotating plate 5. In this process, the falling of each stainless steel tube 3 is carried out synchronously, so the gap between two adjacent stainless steel tubes 3 always exists; Figure 6 As shown, until the driving group drives the telescopic block 6 to fully extend, the rotating plate 5 is completely rotated into the storage groove 12, and the stainless steel tube 3 without the support of the rotating plate 5 will fall down, and each fully extended telescopic block 6 will block the stainless steel tube 3 above it from continuing to fall, directly avoiding the phenomenon that the stainless steel tubes 3 collide with each other when falling, but there is no telescopic block 6 blocking the bottom, so the stainless steel tube 3 at the bottom will directly fall onto the discharge port 102 to complete the automatic discharge effect, that is, the feeding step of one stainless steel tube 3 is completed;

[0036] Since each stainless steel tube 3 will fall from the rotating plate 5 to the telescopic block 6 below it, there will be a vacant position for a stainless steel tube 3 at the top. At this time, a stainless steel tube 3 can be added to the feeding frame 1 from the feed port 101 through the feeding assembly. At this time, both ends of the newly added stainless steel tube 3 cover the two rotating plates 5 retracted in the storage groove 12, and then the driving assembly controls the telescopic block 6 to retract. At this time, the driving assembly will drive the rotating plate 5 to gradually turn away from the storage groove 12 through the linkage assembly. During this process, the position of the stainless steel tube 3 supported by the telescopic block 6 does not move until the telescopic block 6 is completely retracted. At this time, the rotating plate 5 is completely turned away from the storage groove 12, and the stainless steel tube 3 that loses the support of the telescopic block 6 will fall onto the telescopic block 6 and be supported by the telescopic block 6 again, and a new feeding cycle is entered at this time.

[0037] By alternately arranging the rotating plate 5 and the telescopic block 6 in the feeding frame 1, and through the action of the driving component and the linkage component, the rotating plate 5 and the telescopic block 6 alternately support the stainless steel tube 3, and each switching of the alternate support will cause the stainless steel tube 3 to fall, and this cycle is carried out to achieve continuous feeding of the stainless steel tube 3, and each stainless steel tube 3 will be supported by the rotating plate 5 or the telescopic block 6 during its falling process, so that there is always a gap between two adjacent stainless steel tubes 3, so that the stainless steel tubes 3 can be prevented from being stacked together and from hitting each other up and down multiple times when falling;

[0038] And when the rotating plate 5 rotates into the receiving groove 12, one end of the rotating plate 5 will be closer and closer to the telescopic block 6, which can shorten the distance that the stainless steel tube 3 falls from the telescopic block 6 to the rotating plate 5. At this time, the stainless steel tube 3 slides along the plate surface of the rotating plate 5, and finally falls on the telescopic block 6. Due to the extremely short height difference between the rotating plate 5 and the telescopic block 6, the impact force generated when the stainless steel tube 3 falls can be greatly reduced. Similarly, when the rotating plate 5 rotates away from the receiving groove 12, the distance that the stainless steel tube 3 falls from the rotating plate 5 to the telescopic block 6 can also be shortened, and the impact force generated when falling can also be reduced.

[0039] like Figure 4-Figure 7As shown, as a preferred embodiment of the present invention, the driving assembly includes a linkage block 601, a waist-shaped groove 10, a lifting plate 9, an inclined groove 901 and an electric cylinder 11, the waist-shaped groove 10 is opened in the feeding frame 1, each waist-shaped groove 10 corresponds to a telescopic block 6, the lifting plate 9 is slidably installed in the feeding frame 1, the inclined groove 901 is opened on the lifting plate 9, which is inclined, and the horizontal height of the end close to the stainless steel pipe 3 is lower than the horizontal height of the end away from the stainless steel pipe 3, each inclined groove 901 corresponds to a waist-shaped groove 10, the linkage block 601 is fixedly installed at the end of the telescopic block 6 away from the stainless steel pipe 3, it is slidably connected to the inclined groove 901, and it is slidably connected to the waist-shaped groove 10, the electric cylinder 11 is fixedly installed in the feeding frame 1, and its movable end is fixedly connected to the lifting plate 9, and the electric cylinder 11 is connected to an external controller.

[0040] In one case of this embodiment, it should be noted that the electric cylinder 11 and the external controller described in the present invention are both prior arts, and the present invention does not improve them. Therefore, it is not necessary to disclose their specific mechanical structures and circuit structures, and it does not affect the integrity of the present invention.

[0041] In actual application of this embodiment, when the external controller controls the electric cylinder 11 to extend, it will push the lifting plate 9 down, and the position of the linkage block 601 in the lifting plate 9 will change, thereby driving the position of the linkage block 601 in the waist-shaped groove 10 to change, and the change in the position of the linkage block 601 will drive the corresponding change of the telescopic block 6. Further, according to the inclination direction of the inclined groove 901, it can be judged that when the lifting plate 9 descends, it will drive the telescopic block 6 to move away from the stainless steel pipe 3, that is, the telescopic block 6 is retracted at this time; conversely, when the external controller controls the electric cylinder 11 to contract, it will drive the telescopic block 6 to extend. Through this structure, the synchronous control of the movement of each telescopic block 6 can be achieved.

[0042] like Figure 1-Figure 8 As shown, as a preferred embodiment of the present invention, the linkage assembly includes a gear 7 and a tooth plate 8, the gear 7 is rotatably mounted on the feeding frame 1, each gear 7 corresponds to a rotating plate 5, the gear 7 is fixedly connected to the rotating plate 5, the tooth plate 8 is slidably mounted on the feeding frame 1, it is meshed with the gear 7, and it is fixedly connected to the lifting plate 9.

[0043] In practical application, this embodiment is based on Figure 8Taking the direction shown as an example, the rise of the lifting plate 9 can drive the tooth plate 8 to rise synchronously, and the tooth plate 8 meshes with the gear 7, so that the gear 7 can rotate counterclockwise, thereby driving the rotating plate 5 to rotate counterclockwise, that is, the rotating plate 5 rotates into the storage groove 12, and the rise of the lifting plate 9 will drive the telescopic block 6 to extend; conversely, the descent of the lifting plate 9 can drive the telescopic block 6 to retract, and the rotating plate 5 will rotate away from the storage groove 12, thereby achieving the effect of synchronously controlling the telescopic block 6 and the rotating plate 5, thereby controlling the stainless steel pipes 3 to descend one by one, and realizing the purpose of automatic feeding.

[0044] like Figure 1-Figure 4 As shown, as a preferred embodiment of the present invention, the contact surfaces of the rotating plate 5 and the telescopic block 6 with the inner wall of the stainless steel tube 3 are both provided with flexible pads.

[0045] In one case of this embodiment, the flexible pad may be made of rubber, silicone and other components, which is not specifically limited in this embodiment.

[0046] In actual application of this embodiment, no matter the stainless steel tube 3 slides from the rotating plate 5 to the telescopic block 6 or the stainless steel tube 3 slides from the telescopic block 6 to the rotating plate 5, the stainless steel tube 3 will collide with the components that block its falling. By providing a flexible pad on the contact surface between the rotating plate 5 and the telescopic block 6 and the inner wall of the stainless steel tube 3, the impact force caused by the collision can be reduced, thereby further preventing the inner wall of the stainless steel tube 3 from being damaged.

[0047] like Figure 1-Figure 4 As shown, as a preferred embodiment of the present invention, the bottom plate of the discharge port 102 is arranged at an angle, and when the rotating plate 5 rotates into the receiving groove 12, the stainless steel tube 3 at the bottom of the feeding frame 1 fits with the bottom plate of the discharge port 102.

[0048] In actual application of this embodiment, the bottom plate of the discharge port 102 is arranged to be inclined. When the stainless steel tube 3 falls onto the discharge port 102, it will automatically roll down to achieve the effect of automatic discharge. In addition, the horizontal height of one side of the discharge port 102 is higher in the inclined arrangement state. When the rotating plate 5 rotates into the storage groove 12, the bottom stainless steel tube 3 slides along the plate surface of the rotating plate 5 and directly adheres to the discharge port 102, thereby avoiding the problem that the stainless steel tube 3 hits the discharge port 102 when being discharged, thereby causing unnecessary risks.

[0049] like Figure 2-Figure 3As shown, as a preferred embodiment of the present invention, the feeding assembly includes a feeding table 2, a first feeding trough 201, a second feeding trough 202 and a lifting platform 4, the feeding table 2 is fixedly installed on the feeding frame 1, and it is on the same side as the feeding port 101, the second feeding trough 202 is opened on the feeding table 2, it is inclined, and its discharge end faces the feeding port 101, the horizontal height of the feeding end of the second feeding trough 202 is higher than the horizontal height of the discharge end, the first feeding trough 201 is opened on the feeding table 2, it is inclined, and its trough bottom is parallel to the top surface of the second feeding trough 202, and the first feeding trough 201 is provided with There are multiple stainless steel pipes 3, and the lifting platform 4 is slidably installed in the feeding platform 2, and its top is parallel to the top surface of the second feeding trough 202, and it is located between the first feeding trough 201 and the second feeding trough 202. An output source for driving the lifting platform 4 to rise and fall is provided in the feeding platform 2, and the output source is connected to an external controller. The lifting platform 4 intermittently cooperates with the stainless steel pipes 3. When the output source drives the lifting platform 4 to descend to the lowest point, the discharge end of the first feeding trough 201 is connected to the feed end of the lifting platform 4; when the output source drives the lifting platform 4 to rise to the highest point, the discharge end of the lifting platform 4 is connected to the feed end of the second feeding trough 202.

[0050] In one case of this embodiment, the output source may be a cylinder, an electric telescopic rod or other components, or other mechanisms capable of achieving lifting motion, which is not specifically limited in this embodiment.

[0051] In actual application of this embodiment, the stainless steel tube 3 in the first feed trough 201 can be placed manually, and the external controller drives the lifting platform 4 to descend to the lowest point. At this time, the first feed trough 201 and the top surface of the lifting platform 4 form an inclined slope, and the stainless steel tube 3 will slide along the plate surface of the first feed trough 201 to the lifting platform 4; then the external controller drives the lifting platform 4 to rise to the highest point, and the lifting platform 4 will drive the stainless steel tube 3 above it to rise together. At this time, the top surface of the lifting platform 4 and the second feed trough 202 form an inclined slope, and the stainless steel tube 3 on the lifting platform 4 will roll along the inclined slope into the feed port 101, completing the replenishment of the number of stainless steel tubes 3 in the feeding frame 1, ensuring the continuity of filling and feeding, and ensuring that the number of stainless steel tubes 3 in the feeding frame 1 is constant.

[0052] like Figure 3 As shown, as a preferred embodiment of the present invention, when the electric cylinder 11 is fully extended, the output source controls the lifting platform 4 to rise to the highest point; when the electric cylinder 11 is fully retracted, the output source controls the lifting platform 4 to descend to the lowest point.

[0053] In actual application of this embodiment, when the external controller controls the electric cylinder 11 to fully extend, the stainless steel tube 3 has just been unloaded, that is, the rotating plate 5 is completely received in the receiving groove 12, and the telescopic blocks 6 are all fully extended, and each telescopic block 6 supports a stainless steel tube 3, and a vacancy of a stainless steel tube 3 appears at the top. When the external controller controls the electric cylinder 11 to fully extend, the output source is synchronously controlled to control the lifting platform 4 to rise to the highest point. At this time, a stainless steel tube 3 in the first feeding trough 201 will be output to the lifting platform 4. It is sent to the feed port 101 to fill the vacant position. At this time, the two ends of the uppermost stainless steel tube 3 will completely cover the receiving groove 12, and it abuts against the stainless steel tube 3 below it; and when the electric cylinder 11 is fully contracted, that is, the telescopic block 6 is completely retracted, and the rotating plate 5 turns away from the receiving groove 12, and the stainless steel tube 3 will fall from the telescopic block 6 to the rotating plate 5, and the uppermost stainless steel tube 3 will be supported by the rotating plate 5 and will not fall, thereby forming a gap between the two adjacent stainless steel tubes 3 to avoid collision during the subsequent feeding process.

[0054] like Figure 2-Figure 5 As shown, as a preferred embodiment of the present invention, the horizontal height of the discharge end of the second feed trough 202 is slightly higher than the horizontal height of the uppermost telescopic block 6.

[0055] In actual application of this embodiment, when the stainless steel pipe 3 in the first feed trough 201 is transported by the lifting platform 4, it will roll from the second feed trough 202 to the feed port 101. There is a height difference when rolling. At this time, the rolling stainless steel pipe 3 will hit the stainless steel pipe 3 supported by the uppermost telescopic block 6. Therefore, the horizontal height of the discharge end of the second feed trough 202 is designed to be slightly higher than the horizontal height of the uppermost telescopic block 6, which can minimize the impact force of the stainless steel pipe 3.

[0056] The working principle of the present invention: the above embodiment of the present invention provides an automatic feeding mechanism for stainless steel pipe processing. When feeding is needed, the telescopic block 6 is controlled to extend by the driving component. At this time, the driving component drives the rotating plate 5 to rotate into the receiving groove 12 through the linkage component. As the rotating plate 5 rotates, the inner walls of the two ends of the stainless steel pipe 3 will gradually slide down along the plate surface of the rotating plate 5. In this process, the falling of each stainless steel pipe 3 is carried out synchronously, so the gap between two adjacent stainless steel pipes 3 exists all the time until the driving group drives the telescopic block 6 to fully extend, and the rotating plate 5 is fully transferred to the receiving groove 12. At this time, the stainless steel pipe 3 that has lost the support of the rotating plate 5 will fall, and each fully extended telescopic block 6 will block the stainless steel pipe 3 above it from continuing to fall, directly avoiding the phenomenon that the stainless steel pipes 3 collide with each other when falling, but there is no telescopic block 6 to block the bottom, so the stainless steel pipe 3 at the bottom will directly fall onto the discharge port 102 to complete the automatic discharge effect, that is, the feeding step of one stainless steel pipe 3 is completed.

[0057] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
