TECHNICAL FIELD

[0001] The utility model relates to steel bucket production technical field more specifically, relate to a kind of expansion cone mechanism of steel bucket automatic production line. BACKGROUND

[0002] Steel bucket is one of traditional containers, and occupies a very important position in traditional containers. Steel bucket evolves from the function of temporarily storing the contents to today's industrial packaging, sales packaging, transportation packaging, etc. During the production of steel bucket, the end of the tank body needs to be expanded. When expanding, the barrel body is sleeved on an expansion cone mold, positioned and constrained, and then another expansion cone mold is inserted and expanded by a hydraulic cylinder. Generally, a fixed specification is used that matches the tank body. If other specifications of tank body need to be processed, the expansion cone mold needs to be disassembled, adjusted and replaced as a whole, which is time-consuming and labor-intensive. In view of this, we propose an expansion cone mechanism of steel bucket automatic production line. SUMMARY

[0003] The utility model aims to overcome the shortcomings of the prior art, meet the needs of reality, and provide an expansion cone mechanism of steel bucket automatic production line to solve the technical problem of time-consuming and labor-intensive adjustment and replacement when processing different tank bodies.

[0004] To solve the above technical problems, the utility model provides the following technical scheme: an expansion cone mechanism of steel bucket automatic production line, comprising a connecting frame, a restraint ring is installed at the bottom of the connecting frame, a plurality of expansion cone arc plates are arranged on the outer periphery of the restraint ring, the lower half of each expansion cone arc plate is an inwardly inclined inclined surface and forms a lower expansion cone, a plurality of restraint blocks are connected to the expansion cone arc plates, the restraint blocks pass through the restraint ring and are connected to slope blocks at one end, a plurality of stamping seats are provided on one side of the slope blocks, and an adjustment unit is provided between the stamping seats.

[0005] Preferably, an inner cavity is formed in the restraint ring for the restraint blocks to pass through, and the restraint blocks are attached to the inner cavity.

[0006] Preferably, the expansion cone arc plates are arc-fan-shaped structures, springs are provided on one side of the expansion cone arc plates, and the springs are arranged inside the restraint ring.

[0007] Preferably, a sliding plate is connected to the outer periphery of the stamping seat, and the sliding plate is limitingly slid along the inner wall of the restraint ring at one end.

[0008] Preferably, the adjustment unit comprises a threaded sleeve, the outer periphery of the threaded sleeve is connected to the center of the stamping seat, and an adjustment screw is screw-mounted in the center of the threaded sleeve.

[0009] Preferably, a fixing plate is rotatably connected to the top of the adjusting screw, the bottom of the fixing plate is fixed to the top of the connecting frame, and fastening nuts that constrain the adjusting screw are threadedly connected to both the top and bottom of the fixing plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model uses a fan-shaped structure design of multiple expanding cone arc plates and multiple expanding cone arc plates to form a lower expanding cone. The design of the inner inclined slope of the lower half of the expanding cone arc plate makes it easy to insert multiple expanding cone arc plates into the can opening. Combined with the contact between the ramp block and the stamping seat and the threaded connection between the threaded sleeve and the adjusting screw, only the rotation of the adjusting screw needs to be adjusted to make the stamping seat support the ramp block and open the expanding cone arc plate. It can be steplessly adjusted for different can bodies, solving the problem of time-consuming and labor-intensive adjustment and replacement when processing different can bodies.

[0012] 2. This utility model also improves the stability of the expansion cone plate by fitting the constraint block and the inner cavity of the constraint ring. The tension of the spring can make the expansion cone plate have a force that moves towards the center. In addition, the cooperation of the two fastening nuts can ensure the stability of the adjusting screw, further solving the problem of poor stability. Attached Figure Description

[0019] like Figs. 1 to 4As shown, the present invention relates to an expansion cone mechanism for an automatic steel bucket production line, comprising a connecting frame 1, a constraint ring 2 installed at the bottom of the connecting frame 1, multiple expansion cone arc plates 3 arranged around the outer periphery of the constraint ring 2, the lower half of the multiple expansion cone arc plates 3 being inwardly inclined slopes forming a lower expansion cone, several constraint blocks 4 connected to the expansion cone arc plates 3, the expansion cone arc plates 3 having an arc fan-shaped structure, a spring 8 provided on one side of the expansion cone arc plate 3, the spring 8 being located inside the constraint ring 2, an inner cavity for the constraint blocks 4 to pass through on the constraint ring 2, the constraint blocks 4 fitting into the inner cavity, the constraint blocks 4 penetrating the constraint ring 2 and being connected at one end to a ramp block 5, a stamping seat 6 provided on one side of the multiple ramp blocks 5, the stamping seat 6 fitting into the ramp block 5, a sliding plate 9 connected to the outer periphery of the stamping seat 6, one end of the sliding plate 9 being connected to the inner periphery of the constraint ring 2. The wall-limiting sliding mechanism allows the stamping seat 6 to move up and down without rotating. An adjustment unit 7 is provided between multiple stamping seats 6. The adjustment unit 7 includes a threaded sleeve 701, whose outer periphery is connected to the center of the stamping seat 6. An adjusting screw 702 is threaded onto the center of the threaded sleeve 701. To ensure the stability of the adjusting screw 702, a fixing plate 10 is rotatably connected to the top of the adjusting screw 702. The bottom of the fixing plate 10 is fixed to the top of the connecting frame 1. Both the top and bottom of the fixing plate 10 are threaded with fastening nuts 11 to constrain the adjusting screw 702. When the fastening nuts 11 are tightened, their sides are in contact with the fixing plate 10. Fixing is achieved through the constraint of the opposite-direction threaded connections on both sides.

[0020] Working principle: When adjustment is required, use a tool to constrain the adjusting screw 702, and then tighten the two fastening nuts 11 to separate it from the fixed plate 10, providing space for adjustment. At this time, rotate the adjusting screw 702 to move the threaded sleeve 701 up, causing the stamping seat 6 to descend and further press the ramp 5, which will cause multiple expansion cone arc plates 3 to move outward synchronously, thus completing the adjustment of the expansion cone diameter. With the help of the external drive structure, the entire mechanism will descend, and the can opening can be processed.

[0021] To improve automation, the fastening nut 11 is removed, and a motor is used to rotate and prevent the adjusting screw 702 from rolling back.

[0022] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
