Description

Technical Field

[0001] This utility model relates to the field of roller processing technology, and in particular to a multi-station chain roller cold heading forming mechanism. Background Technology

[0002] Chain rollers are key components in transmission chains. Their structure includes inner chain plates, outer chain plates, pins, bushings, and rollers. The main feature of roller chains is that the inner chain plates are fixed to the bushings, outer chain plates, and pins with interference fits to form inner and outer chain links. The rollers are fitted with the bushings, and the bushings are fitted with the pins with clearance fits. During operation, the rollers roll along the sprocket tooth profile, reducing tooth wear. The main wear of the chain occurs on the contact surface between the pins and bushings. A cold heading machine is a device that applies pressure to metal blanks at room temperature, causing them to undergo plastic deformation in a mold cavity and be formed into a specified shape and size. A multi-station cold heading machine can cold head multiple rollers simultaneously.

[0003] When the blank is stamped in the cold heading machine, the inhomogeneity of the material may cause differences in the metal flow resistance, resulting in incomplete forming of the roller and the generation of waste. This waste not only reduces the product yield, but may also adhere to the roller surface, causing inconvenience to subsequent cleaning work and affecting production efficiency and product quality.

[0004] To address the aforementioned issues, this application proposes a multi-station chain roller cold heading mechanism. Utility Model Content

[0005] Based on the technical problems existing in the background art, this utility model proposes a multi-station chain roller cold heading forming mechanism.

[0006] This utility model proposes a multi-station chain roller cold heading forming mechanism, including a machine base and a mold base mounted on the machine base;

[0007] The mold base has several spaced molds mounted on its side, and the machine base is equipped with a stamping assembly for stamping the blanks inside the molds.

[0008] The machine base has a material guiding chamber located below the mold, and the material guiding chamber extends through the top and side of the machine base. A material guiding filter is installed in the material guiding chamber for filtering the workpiece.

[0009] The material guide filter element is connected to a chip discharge pipe on its side. An air blowing device is installed on the material guide filter element for blowing air into it, and the air blowing device is used to discharge waste chips through the chip discharge pipe.

[0010] Preferably, the material guiding filter includes a material guiding seat, filter holes and a cavity. The material guiding seat is installed in the material guiding cavity. An inclined first material guiding surface is formed on the material guiding seat. A cavity is opened in the material guiding seat. Filter holes are densely arranged and communicate with the cavity on the first material guiding surface of the material guiding seat.

[0011] Preferably, an electromagnetic base is installed inside the cavity, and an inclined second guide slope is formed on the electromagnetic base.

[0012] Preferably, the air blowing component includes a split pipe, a first air blowing pipe, a second air blowing pipe, and an air inlet pipe. The split pipe is installed on the outer side of the guide seat. The two ends of the split pipe are respectively connected to the first air blowing pipe and the second air blowing pipe. The end of the first air blowing pipe away from the split pipe passes through the top of the guide seat and faces the electromagnetic base. The end of the second air blowing pipe away from the split pipe passes through the outer side of the machine base and faces the chip removal pipe. The middle part of the split pipe is connected to the air inlet pipe. The end of the air inlet pipe away from the split pipe is connected to the air pump.

[0013] Preferably, the stamping assembly includes a fixed base, cylinders, and stamping heads. A fixed base located on one side of the mold is mounted on the machine base. A plurality of cylinders are spaced apart and mounted on the side of the fixed base. The driving ends of the plurality of cylinders are all connected to stamping heads located between the fixed base and the mold base. The plurality of stamping heads are respectively facing the plurality of molds.

[0014] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0015] By incorporating a material guide filter, chip removal pipe, and air blowing device, the blank material can be placed in several molds. The stamping assembly then simultaneously stamps the blank material in each mold. The stamped rollers fall into the material guide chamber. As they roll down the material guide filter, the waste material carried on them is filtered and falls into it. High-pressure gas is then blown into the material guide filter by the air blowing device, expelling the waste material through the chip removal pipe. This structure effectively removes waste material adhering to the roller surface by using the material guide filter, reducing the impact of waste material on subsequent cleaning and improving production efficiency. Simultaneously, the air blowing device ensures the continuous and effective operation of the material guide filter, preventing blockage caused by waste material accumulation and further improving product yield and quality.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] like Figure 1-3 As shown, the present invention proposes a multi-station chain roller cold heading forming mechanism, which includes a machine base 1 and a mold base 2 mounted on the machine base 1.

[0022] In this embodiment, a plurality of spaced molds 3 are mounted on the side of the mold base 2, and a stamping assembly 4 for stamping the blanks inside the molds 3 is mounted on the machine base 1. The stamping assembly 4 includes a fixed seat 41, a cylinder 42 and a stamping head 43. A fixed seat 41 located on one side of the mold 3 is mounted on the machine base 1, and a plurality of spaced cylinders 42 are mounted on the side of the fixed seat 41. The driving ends of the plurality of cylinders 42 are all connected to the stamping head 43 located between the fixed seat 41 and the mold base 2, and the plurality of stamping heads 43 are respectively facing the plurality of molds 3.

[0023] In this embodiment, a material guiding chamber 5 is provided in the base 1, located below the mold 3, and the material guiding chamber 5 extends through the top and side of the base 1. A material guiding filter element 6 for filtering the workpiece is installed in the material guiding chamber 5. The material guiding filter element 6 includes a material guiding seat 61, filter holes 62 and a cavity 63. The material guiding seat 61 is installed in the material guiding chamber 5. An inclined first material guiding slope is formed on the material guiding seat 61. A cavity 63 is provided in the material guiding seat 61. Filter holes 62, which are densely arranged and communicate with the cavity 63, are provided on the first material guiding slope of the material guiding seat 61.

[0024] In this embodiment, a chip removal pipe 7 is connected to the side of the material guide filter 6. An air blowing component 8 is installed on the material guide filter 6 for blowing air into its interior. The air blowing component 8 is used to discharge waste chips through the chip removal pipe 7. The air blowing component 8 includes a diversion pipe 81, a first air blowing pipe 82, a second air blowing pipe 83, and an air inlet pipe 84. A diversion pipe 81 is installed on the outside of the material guide seat 61. The two ends of the diversion pipe 81 are respectively connected to the first air blowing pipe 82 and the second air blowing pipe 83. The end of the first air blowing pipe 82 away from the diversion pipe 81 passes through the top of the material guide seat 61 and is set towards the electromagnetic seat 9. The end of the second air blowing pipe 83 away from the diversion pipe 81 passes through the outside of the machine base 1 and is directly opposite to the chip removal pipe 7. The middle part of the diversion pipe 81 is connected to the air inlet pipe 84. The end of the air inlet pipe 84 away from the diversion pipe 81 is connected to the air pump.

[0025] In a specific embodiment, an electromagnetic base 9 is installed inside the cavity 63, and an inclined second guide slope is formed on the electromagnetic base 9.

[0026] It should be noted that: the blanks can be placed in several molds 3, and then several cylinders 42 drive several stamping heads 43 to simultaneously stamp the blanks in the molds 3. The stamped rollers fall into the guide chamber 5 and roll down the first guide slope on the guide seat 61. The waste carried on the rollers can be filtered through the filter holes 62 and fall into the cavity 63. During this process, the electromagnetic seat 9 can be energized to generate magnetism. When the rollers roll down the guide seat 61, the waste carried on the rollers can quickly enter the cavity 63 and be attracted to the surface of the electromagnetic seat 9 by the magnetic attraction of the electromagnetic seat 9. After the rollers have finished dropping, the electromagnetic seat 9 can be de-energized, allowing the waste to slide down the second guide slope on the electromagnetic seat 9. Then the blanks can be removed from the guide chamber 5. Air pipe 84 connects to the air pump, and high-pressure gas enters the diversion pipe 81. Then, it is blown along the first air blowing pipe 82 onto the second guide slope of the electromagnetic base 9, blowing the waste to the bottom of the electromagnetic base 9. Then, high-pressure gas is blown into the chip discharge pipe 7 through the second air blowing pipe 83. The waste at the bottom of the electromagnetic base 9 can be discharged through the chip discharge pipe 7 under the carry of the high-pressure gas. This structure uses the guide filter 6 to filter the stamped roller, which can effectively remove the waste attached to the roller surface, thereby reducing the impact of waste on subsequent cleaning work and improving production efficiency. At the same time, the waste is discharged through the air blowing device 8, ensuring the continuous and effective operation of the guide filter 6, avoiding the blockage problem caused by the accumulation of waste, and further improving the product yield and quality.
