Description

Technical Field

[0001] This application relates to the field of bolt processing equipment technology, and more specifically, to a round bar feeding device for bolt making. Background Technology

[0002] Bolts are commonly used fasteners in mechanical manufacturing. Bolts are usually made of materials such as carbon steel, stainless steel or copper, among which carbon steel round bars (such as medium carbon steel No. 35 and No. 45) are a common choice.

[0003] In related technologies, round bars need to be cut into multiple fixed-length segments by a cutting machine, and then these fixed-length segments of round bars are fed into a furnace for high-temperature treatment. Finally, the round bars after high-temperature treatment are subjected to heat-forging to form hexagonal nuts.

[0004] Because there is a time interval between the feeding of round bars and the high-temperature treatment, the round bars need to be fed periodically. Traditionally, operators need to replenish the round bars into the furnace feed at regular intervals. This method is labor-intensive for operators, and operators are prone to fatigue, leading to fluctuations in the feeding interval. Therefore, how to solve the above-mentioned drawbacks is one of the urgent problems to be solved. Utility Model Content

[0005] In view of this, embodiments of this application provide a round bar feeding device for bolt making.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A bolt-making round bar feeding device, comprising:

[0008] Base;

[0009] A shelf, which is fixedly mounted on the top of the base;

[0010] Multiple feeding frames are arranged at an angle from top to bottom inside the shelf, with the ends of adjacent feeding frames connected to each other, and multiple round bars arranged inside each feeding frame.

[0011] A fan-shaped lever is rotatably disposed at the discharge end of the bottommost feeding frame, and has an arc-shaped groove along the radial direction that matches the outer diameter of the round bar.

[0012] A drive motor is provided, located beside the feeding frame and fixed coaxially with the center of the sector-shaped lever via a drive shaft; wherein...

[0013] The fan-shaped lever abuts against the round bar through its arc-shaped outer wall. When the arc-shaped groove contacts the round bar, the fan-shaped lever flips the round bar to the side through the arc-shaped groove.

[0014] In some possible implementations, the tip of the arcuate slot is provided with a rounded corner.

[0015] In some possible implementations, the fan-shaped lever is provided with two sets of arc-shaped slots symmetrically along the radial direction, and the two sets of arc-shaped slots are symmetrical to each other.

[0016] In some possible implementations, the surface of the fan-shaped paddle has reinforcing ribs distributed radially.

[0017] In some possible implementations, the fan-shaped lever consists of a first lever and a second lever, which are fixed together by fastening bolts on the reinforcing rib.

[0018] In some possible implementations, the inner wall of the feeding frame is coated with a polishing layer, and the two ends of the round bar are in contact with the feeding frame through the polishing layer.

[0019] The bolt-making round bar feeding device provided in this application embodiment has at least the following beneficial effects:

[0020] In the bolt-making round bar feeding device provided in this application embodiment, multiple layers of feeding frames are arranged at a certain inclination angle inside the storage rack. Adjacent feeding frames are connected end-to-end to form a stepped storage channel. Each feeding frame can store multiple round bars of a fixed length. A fan-shaped lever is rotatably installed at the discharge end of the bottom feeding frame. The arc-shaped slot of the fan-shaped lever precisely matches the outer diameter of the round bar. When the fan-shaped lever rotates, it flips the round bar in the feeding frame to the side through the arc-shaped slot, thereby achieving automatic feeding. Using the above structural design, automatic feeding can be achieved through the fan-shaped lever, and the feeding frequency of the round bars can be controlled by adjusting the speed of the drive motor, thus matching the processing rhythm of furnaces of different specifications.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] like Figures 1-4 As shown in the embodiment of this application, the bolt-making round bar 400 feeding device includes a base 100, a shelf 200, multiple unloading frames 300, a fan-shaped lever 500, and a drive motor 600. The base 100 is the supporting structure of the feeding device and is welded from multiple 304 stainless steel square bars. Rubber leveling pads are installed at each of the four corners of the base 100's bottom. These leveling pads ensure that the base 100 remains level on uneven workshop floors, preventing the round bar 400 from shifting due to tilting during the feeding process.

[0037] A shelf 200 is bolted to the top of the base 100. The shelf 200 has a frame structure. The shelf 200 is also welded from 304 stainless steel square tubing. Multiple feed frames 300 are distributed from top to bottom within the shelf 200. Each feed frame 300 is made of 304 stainless steel of a certain thickness and is bent into shape. Each feed frame 300 is arranged in an inclined direction. Furthermore, adjacent feed frames 300 are interconnected end-to-end. The distribution of the multiple feed frames 300 within the shelf 200 is similar to that of a staircase.

[0038] A fan-shaped lever 500 is rotatably mounted on the discharge end of the bottom-level feed frame 300 of the shelf 200. Specifically, the fan-shaped lever 500 has an arc-shaped slot 510 along its radial direction. The outer diameter of the arc-shaped slot 510 is equal to the outer diameter of the round bar 400 placed inside the feed frame 300, so the round bar 400 can enter the arc-shaped slot 510 of the fan-shaped lever 500. Preferably, the tip of the arc-shaped slot 510 is provided with a rounded corner surface. The rounded corner surface of the tip of the arc-shaped slot 510 can replace the original sharp edge, forming a surface contact when it comes into contact with the round bar 400, thereby preventing the tip of the arc-shaped slot 510 from scratching the surface of the round bar 400.

[0039] In this embodiment, a drive motor 600 is fixed to the side of the feeding frame 300 by motor mount bolts. The drive shaft of the drive motor 600 passes through the side wall of the feeding frame 300 and is coaxially fixed with the fan-shaped lever 500. Therefore, when the drive motor 600 rotates, it can drive the fan-shaped lever 500 to rotate synchronously, and transport the round bar 400 to the other side through the arc-shaped slot 510. During the rotation and transportation process, the fan-shaped lever 500 can abut against the round bar 400 located in the feeding frame 300 through its arc-shaped surface, thereby realizing the feeding function of the round bar 400. Since the round bars 400 are arranged along their length in each feeding frame 300, the round bars 400 in the upper feeding frame 300 can be automatically replenished to the lower layer by gravity.

[0040] Preferably, the inner wall of the feeding frame 300 is coated with a polishing layer, the length of the round bar 400 is adapted to the inner width of the feeding frame 300, and the two sides of the round bar 400 are in contact with the feeding frame 300 through the polishing layer.

[0041] In the bolt-making round bar 400 feeding device provided in this application embodiment, multiple layers of feeding frames 300 are arranged at a certain inclination angle inside the shelf 200. The upper and lower adjacent feeding frames 300 are connected end to end to form a stepped storage channel. Each feeding frame 300 can store multiple fixed-length round bars 400. A fan-shaped lever 500 is rotatably arranged at the discharge end of the bottom feeding frame 300. The arc-shaped slot 510 of the fan-shaped lever 500 is precisely matched with the outer diameter of the round bar 400. When the fan-shaped lever 500 rotates, it flips the round bars 400 in the feeding frame 300 to the side through the arc-shaped slot 510, thereby realizing the automatic feeding function. With the above structural design, the automatic feeding function can be realized by the fan-shaped lever 500, and the feeding frequency of the round bars 400 can be controlled by adjusting the speed of the drive motor 600, thereby matching the processing rhythm of furnaces of different specifications.

[0042] In some embodiments, the fan-shaped lever 500 is provided with two sets of arc-shaped slots 510 symmetrically in the radial direction, and the two sets of arc-shaped slots 510 are symmetrical to each other. By setting two sets of symmetrical arc-shaped slots 510, the function of feeding two rods in one rotation can be realized, that is, the feeding function of two round rods 400 can be realized by rotating once, which can meet the needs of working environments with high feeding frequency.

[0043] In some embodiments, such as Figure 5 and Figure 6 As shown, the fan-shaped lever 500 has reinforcing ribs 540 distributed radially on its surface. The fan-shaped lever 500 consists of a first lever 520 and a second lever 530, which are fixed together by fastening bolts 550 on the reinforcing ribs 540. By designing the fan-shaped lever 500 as a modular structure, it can be detachably connected to the rotating shaft. In practical use, different sizes of arc-shaped slots 510 can be replaced using this structure to meet the rapid changeover requirements of mass production of multi-specification bolts.
