Description

Technical Field

[0001] The utility model relates to the technical field of industrial production equipment, in particular to a horizontal feeding mechanism. Background Art

[0002] In the process of continuous stamping to produce small parts, the raw materials are metal coils. The metal coil is placed on a rotatable feed tray, and the end of the metal coil enters the feed mechanism of the stamping machine. The feed is pulled through the feed mechanism on the stamping machine. It was found in production that the pulling mechanism pulled the metal coil intermittently, and each pulling of the metal coil would drive the feed tray to rotate. During this process, when the pulling mechanism temporarily stopped pulling the metal coil, due to inertia, the feed tray would continue to rotate a certain angle, so that part of the metal coil between the feed tray and the feed mechanism was in a relaxed state, and the metal coil on the feed tray would also become loose.

[0057] See also Figures 1 to 4 This embodiment provides a horizontal feeding mechanism, including a base 10, a feeding tray 20, a support frame 30, a first rod 40 and a second rod 60.

[0058] The feeding tray 20 is rotatably disposed on the base 10 for carrying the metal coil, and the end surface of the feeding tray 20 carrying the metal coil faces upward. The lower end of the support frame 30 is connected to the base 10.

[0059] One end of the first rod 40 ( Figure 1 The upper end of the first rod 40 is rotatably connected to the upper end of the support frame 30, and the other end of the first rod 40 is connected to the counterweight assembly 50, and the counterweight assembly 50 can adjust the weight. Figure 1 The upper end of the first rod 40) and one end of the first rod 40 ( Figure 1 The first rod 40 and the second rod 60 are connected to each other (the upper end of the second rod 60), and the other end of the second rod 60 is provided with a limiting mechanism 70. The limiting mechanism 70 can limit the metal coil that is circling to prevent the metal coil from slipping. Specifically, the connection between the first rod 40 and the second rod 60 serves as the rotation center. The rotation axis of the first rod 40 is parallel to the horizontal plane. Specifically, during the rotation of the first rod 40 and the second rod 60, the plane formed by the axes of the two rods is perpendicular to the horizontal plane.

[0060] In this embodiment, Figure 1After the metal coil is released from the feed tray 20, it goes around the limiting mechanism 70 and finally enters the feeding mechanism of the punching machine. The counterweight assembly 50 is used to balance the weight, so that the height of the lower end of the second rod 60 changes, and the metal coil between the feed tray 20 and the feeding mechanism of the punching machine is tensioned to prevent the metal coil on the feed tray 20 from loosening due to the inertial rotation of the metal coil released.

[0061] In one embodiment, the limiting mechanism 70 includes a mounting member 71 , a C-shaped limiting member 72 and a cylindrical guide member 73 .

[0062] The mounting member 71 is connected to the end of the second rod 60 away from the first rod 40. The C-shaped stopper 72 is connected to the mounting member 71. The cylindrical guide member 73 is rotatably arranged at the mouth of the C-shaped stopper 72, and is surrounded by the C-shaped stopper 72 to form a coil passage for the metal coil to pass through. The cylindrical guide member 73 is used to guide the metal coil.

[0063] In this embodiment, the metal coil fed from the feeding tray 20 passes through the existing coil channel and bypasses the cylindrical guide 73 before entering the punching machine. The metal coil contacts the outer wall of the cylindrical guide 73. The metal coil is usually in a strip shape. The rotating cylindrical guide 73 can guide the metal coil so that the metal coil bypassing the cylindrical guide 73 maintains the maximum area contact with the cylindrical guide 73, so that the metal coil is in surface contact when passing through the cylindrical guide 73, which can protect the outer wall of the metal coil and avoid local contact scratches. The rotating cylindrical guide 73 can also make the metal coil conveying smoother.

[0064] In one embodiment, the C-shaped limiting member 72 includes a first connecting portion 721 , a second connecting portion 722 and a third connecting portion 723 .

[0065] The first connection part 721 is connected to the mounting member 71. The second connection part 722 is connected to the first connection part 721. The third connection part 723 is connected to one end of the second connection part 722 away from the first connection part 721, and the third connection part 723 is arranged opposite to the first connection part 721. A strip-shaped through hole 724 extending along the length direction thereof is provided on the third connection part 723. The cylindrical guide member 73 is a sleeve, and a third rod 74 is hingedly connected to one surface of the first connection part 721 facing the third connection part 723, and a locking nut 75 is sleeved after one end of the third rod 74 away from the first connection part 721 passes through the strip-shaped through hole 724, and the locking nut 75 can be abutted against one surface of the third connection part 723 away from the first connection part 721. The cylindrical guide member 73 is coaxially rotatably sleeved on the third rod 74. Specifically, the cylindrical guide member 73 can be connected to the third rod 74 through a coaxial bearing, so that the cylindrical guide member 73 can rotate on the third rod 74.

[0066] In this embodiment, the feed tray 20 is usually placed at a lower position, and the feeding mechanism of the punching machine is arranged on the punching machine with a certain height. In order to ensure smooth feeding of the punching machine, on the one hand, it is necessary to ensure that the part of the metal coil between the feed tray 20 and the punching machine is in a relatively tight state (needs to be tensioned), and on the other hand, it is also necessary to gradually increase the height of this part of the metal coil. Therefore, the limiting mechanism 70 not only supports the metal coil but also plays a role in adjusting the height.

[0067] After the metal coil is replaced during stamping production, the weight of the metal coil between the feed tray 20 and the stamping machine changes. Therefore, it is necessary to adjust the weight of the counterweight assembly 50 so that the weight of the counterweight assembly 50 is balanced with the weight of the metal coil, thereby keeping the metal coil taut to a certain extent. It is also necessary to ensure that the height of the metal coil gradually rises.

[0068] In the process of changing the weight of the counterweight assembly 50, the height of the entire limiting mechanism 70 relative to the feed tray 20 changes, and the swing amplitude of the second rod 60 changes. In order to enable the cylindrical guide 73 to better guide the metal coil, the position of the third rod 74 in the strip through hole 724 can be adjusted so that the cylindrical guide 73 can have a certain degree of deflection relative to the second rod 60, which better fits the moving trajectory of the metal coil.

[0069] In one embodiment, both the inner surface and the outer surface of the third connecting portion 723 are arc surfaces with the rotation axis of the third rod 74 as the axis.

[0070] In this embodiment, the third rod 74 is hinged to the first connection part 721, so that the third rod 74 can swing in the C-shaped limiter 72 to adapt to the moving track of the metal coil. The inner and outer surfaces of the third connection part 723 are arc surfaces, so that the cylindrical guide 73 rotatably arranged on the third rod 74 is more in line with the third connection part 723 when swinging, and the gap between the two is small, which is not easy to cause obstruction to the metal coil. In addition, when the locking nut 75 is tightened, it can also be relatively fully against the outer surface of the third connection part 723 to achieve a stable locking effect. A rubber gasket can also be arranged between the locking nut 75 and the third connection part 723 to enhance the locking effect and avoid slipping.

[0071] In one embodiment, the mounting member 71 is a sleeve, one end of the mounting member 71 is sleeved on the second rod 60 and threadedly connected to the second rod 60 , and the other end of the mounting member 71 is connected to the first connecting portion 721 .

[0072] In this embodiment, the height of the limiting mechanism 70 can be directly adjusted by rotating the mounting member 71 to lift the metal coil, and at the same time, the tension of the metal coil can be changed.

[0073] In one embodiment, the weight assembly 50 includes one or more weight blocks 51 and weight nuts 52.

[0074] The counterweight block 51 can be slidably mounted on the first rod 40 through the opening. The counterweight nut 52 is mounted on the first rod 40 , and the counterweight nut 52 is threadedly connected to the first rod 40 , and the counterweight nut 52 can be abutted against the counterweight block 51 .

[0075] In this embodiment, the height of the limiting mechanism 70 at the lower end of the second rod 60 is adjusted by increasing the number of the counterweight blocks 51 slidably sleeved on the first rod 40 .

[0076] In one embodiment, a stopper 80 is further connected to the support frame 30, and the lower side of one end of the stopper 80 away from the support frame 30 abuts against the metal coil fed out of the feeding tray 20. Specifically, the metal coil fed out of the feeding tray 20 passes under the stopper 80 and then enters the limiting mechanism 70.

[0077] In this embodiment, since the limiting mechanism 70 has a certain height, the metal coil on the feeding tray 20 is fed out by pulling. When the radius of the metal coil becomes smaller and the height of the limiting mechanism 70 is higher, there is a situation where the metal coil no longer drives the feeding tray 20 to rotate and the metal coil is directly pulled out, which easily causes the metal coil to bend and deform. The blocking rod 80 can prevent this from happening.

[0078] In one embodiment, the support frame 30 includes a support column 31 , a mounting seat 32 , a mounting column 33 and a rotating sleeve 34 .

[0079] The lower end of the support column 31 is connected to the base 10. The lower end of the mounting seat 32 is connected to the upper end of the support column 31. One end of the mounting column 33 is connected to the mounting seat 32, and the other end of the mounting column 33 extends horizontally. The rotating sleeve 34 is rotatably sleeved on the mounting column 33. The ends of the first rod 40 and the second rod 60 are both connected to the outer wall of the rotating sleeve 34.

[0080] In one embodiment, the support column 31 is externally threaded with an adjusting sleeve 81; a radial locking hole 811 is opened on the adjusting sleeve 81; a support sleeve 82 is connected to the outer wall of the adjusting sleeve 81; the support sleeve 82 is communicated with the locking hole 811; a locking column 83 is coaxially connected to the end of the blocking rod 80, and the locking column 83 is threadedly connected to the inner wall of the support sleeve 82, and a rubber block 84 is connected to the end of the locking column 83 away from the blocking rod 80, and the rubber block 84 can pass through the locking hole 811 and then abut against the outer wall of the support column 31.

[0081] In this embodiment, after the metal coil is replaced, the height of the baffle rod 80 needs to be adjusted. The locking column 83 can be rotated to drive the rubber block 84 to retreat, and then the baffle rod 80 is rotated around the support column 31 to adjust the height of the baffle rod 80. Then the baffle rod 80 is rotated so that the rubber block 84 abuts against the outer wall of the support column 31 to achieve locking. In addition, after the height of the limit mechanism 70 is adjusted, in addition to adjusting the height, the baffle rod 80 can also be rotated around the support column 31 as needed to adapt, so that the height of the metal coil between the discharge tray and the limit mechanism 70 gradually and steadily increases. Thereby, the entire metal coil is transported more smoothly and smoothly.

[0082] In the specification of the present utility model, a lot of specific details are described. However, it is understood that the embodiments of the present utility model can be practiced without these specific details. In some examples, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
