Description

Technical Field

[0001] This utility model relates to the field of extrusion device technology, and in particular to an extrusion device for machining mechanical parts. Background Technology

[0002] Extrusion is a processing method for mechanical parts. Extrusion processing involves placing the blank into a mold and applying pressure to the blank through the mold, thereby extruding the blank into the desired shape.

[0003] Existing machining processes for tubular mechanical parts include necking, bending, and drilling. After the tubular mechanical parts are cut and shaped, the cross-section needs to be ground, and the necking process is also required to reduce the diameter of the ends of the tubular mechanical parts.

[0004] Existing machines typically use extrusion or spinning to reduce the diameter of tubular mechanical parts, followed by grinding and deburring. Multiple dies used to extrude tubular mechanical parts can be assembled into a frustum shape, with a through hole in the middle corresponding to the size of the reduced diameter of the tubular mechanical parts.

[0005] Because the shape of the mold is fixed, a set of molds can only shrink the end of the tubular mechanical part to one specification. If you want to shrink it to other specifications, you need to change the mold, which makes the operation cumbersome and requires storing multiple molds, which is very inconvenient.

Even though the mold group can correspond to multiple processing diameters, the end face grinding process is completed while the tubular mechanical part is compressed and reduced. Compared with the prior art, it is more convenient and efficient. Attached Figure Description

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0033] Example 1:

[0034] Reference Figures 1-7 The first embodiment of this utility model provides an extrusion device for machining mechanical parts, including...

[0035] Base 1;

[0036] Mold assembly 2; Mold assembly 2 is mounted on base 1 and is used to clamp tubular mechanical parts and to deburr the tubular mechanical parts.

[0037] Mounting ring 3; Mounting ring 3 is fixed to base 1 and used to mount mold assembly 2;

[0038] Clamping block 4; Clamping block 4 is fitted on the outside of mold assembly 2 and is slidably connected to base 1. Clamping block 4 is used to compress mold assembly 2.

[0039] Drive component 5; Drive component 5 is fixedly connected to base 1 and its output end is fixedly connected to clamping block 4;

[0040] Mold group 2 consists of mold 1 21 and mold 22; a first groove 31 is evenly opened on the mounting ring 3; a sliding block 32 is slidably connected in the first groove 31; the sliding blocks 32 are arranged in a radiating manner and each sliding block 32 is fixedly connected to the groove wall of the corresponding first groove 31 by a tension spring 33; the end of the second mold 22 is fixedly connected to the sliding block 32; the mold group 2 consisting of mold 1 21 and mold 22 is arranged in a concentric circle; mold 1 21 and the adjacent second mold 22 are slidably connected by a connecting mechanism 6; a grinding mechanism 7 is provided on the mold group 2 for grinding the end face of the tubular mechanical parts;

[0041] Reference Figures 3-4The connecting mechanism 6 includes a sliding rod 61 and a fixing block 62; the fixing block 62 is fixedly connected to the end face of the first mold 21 away from the clamping block 4; a sliding groove 63 is provided on the end face of the second mold 22 away from the clamping block 4; the sliding rod 61 is slidably connected in the sliding groove 63; the sliding rod 61 on the second mold 22 is fixedly connected to the fixing block 62 on the adjacent first mold 21.

[0042] When processing tubular mechanical parts, the worker first inserts the cut tubular part into mold assembly 2. Then, the worker activates drive component 5 via controller, which pushes clamping block 4 forward, causing its inner wall to contact the outer wall of mold 22. All molds 22 move towards the center of the ring under the push of clamping block 4. Sliding block 32 moves towards the center of mounting ring 3 under the influence of mold 22, pulling tension spring 33. Simultaneously, mold 22 moves along with mold 21 connected to it. The first mold 21 then contacts the tubular mechanical part, compressing it. Eventually, all the first molds 21 come into contact with each other, forming a ring. The part of the tubular mechanical part that is in contact with the first mold 21 is compressed to a size corresponding to the inner wall of the ring formed by the first mold 21. Then, the drive component 5 moves backward with the clamping block 4 back to its original position, thereby pulling the corresponding second mold 22 with the corresponding first mold 21 back to its original position. This completes the extrusion processing of the tubular mechanical part, reducing the diameter of one end.

[0043] When the operator adjusts the size of the tubular mechanical parts after they are extruded and compressed, all the No. 1 molds 21 are pulled away from the clamping block 4, so that the No. 1 molds 21 and the corresponding No. 2 molds 22 slide relative to each other. The sliding rod 61, which is slidably connected in the sliding groove 63 of the No. 2 mold 22, slides outward until the sliding rod 61 is pulled to the top and stuck. At this time, the inner wall of the No. 2 mold 22 is exposed. Thus, when all the No. 2 molds 22 are put together to form a ring, the No. 2 molds 22 can compress the tubular mechanical parts with the corresponding size.

[0044] This invention changes the diameter of the tubular mechanical part after processing by repeatedly pulling the first mold 21 back and forth. When the tubular mechanical part is processed by the second mold 22, the first grinding block 71 fixed on the first mold 21 rubs against the end face of the tubular mechanical part to remove the burrs. Thus, the end face is ground and deburred while the diameter of the tubular mechanical part is reduced, completing the combined processing. The mold group 2 can handle multiple processing diameters and completes the end face grinding process while compressing and reducing the diameter of the tubular mechanical part. Compared with the prior art, this is more convenient and efficient.

[0045] Reference Figure 3 The grinding mechanism 7 includes a first grinding block 71 and a second grinding block 72; the first grinding block 71 is fixedly connected to the end face of the first mold 21 away from the sliding rod 61 and the fixed block 62; the second grinding block 72 is fixedly connected to the end of the inner wall of the first mold 21 near the fixed block 62.

[0046] Reference Figure 1 The base 1 has a drive groove 8; the drive groove 8 has a sliding connection to the mounting tube 81; the mounting tube 81 has a second groove 82 with a shape corresponding to the distribution of the fixing blocks 62; the fixing blocks 62 are slidably connected to the second groove 82; the base 1 has a first electric push rod 83 fixedly connected to it; the output end of the first electric push rod 83 is fixedly connected to the mounting tube 81.

[0047] When mold number 22 moves along with mold number 1, the fixing block 62 slides within the corresponding slot 82. The operator can control the first electric push rod 83 via the controller, causing its output end to retract and move the mounting tube 81 away from the clamping block 4. Simultaneously, the mounting tube 81 moves, carrying all the fixing blocks 62 and the corresponding mold number 21 together. Thus, controlling the movement of the mounting tube 81 controls the movement of all mold number 21, eliminating the need for manual movement of the mold number 21. 1. This eliminates the cumbersome steps and shortens the time required to move the first mold 21. Workers can insert the tubular mechanical part into the first mold 21, allowing the first mold 21 to squeeze and reduce its diameter. Then, the first electric push rod 83 is controlled to pull the first mold 21, exposing the inner wall of the second mold 22. The other end of the tubular mechanical part is then inserted into the second mold 22, allowing the second mold 22 to squeeze and reduce its diameter. This allows both ends of the tubular mechanical part to be squeezed and reduced to different diameters simultaneously, thus enriching the variety of finished tubular mechanical parts.

[0048] When the first mold 21 extrudes the tubular mechanical part, the operator pushes the tubular mechanical part forward, so that the end face of the tubular mechanical part comes into contact with the second grinding block 72. As the first mold 21 moves, the second grinding block 72 rubs against the end face of the tubular mechanical part, thereby grinding away the burrs on the end face of the tubular mechanical part, thus completing the grinding of the tubular mechanical part. Similarly, when the second mold 22 extrudes the tubular mechanical part, the tubular mechanical part comes into contact with the first grinding block 71, and the first grinding block 71 grinds away the burrs on the end face of the tubular mechanical part.

[0049] Example 2:

[0050] This embodiment is based on the previous embodiment, but differs from the previous embodiment in that, specifically, please refer to... Figure 3A cleaning pipe 84 is installed inside the installation pipe 81; a connecting rod 85 is fixedly connected to the cleaning pipe 84; the other end of the connecting rod 85 is fixedly connected to the installation pipe 81; the cleaning pipe 84 is connected to high-pressure gas, and an air outlet 86 is fixedly connected to and connected to the cleaning pipe 84; the air outlet 86 is divided into two groups; the two groups of air outlets 86 are evenly distributed around the axis of the cleaning pipe 84 and correspond to the first grinding block 71 and the second grinding block 72 respectively.

[0051] The high-pressure gas pipe is connected to the cleaning pipe 84, so that the high-pressure gas in the cleaning pipe 84 is sprayed out from the air outlet 86, blowing away the burrs or metal debris that are stuck to the end face of the corresponding No. 1 grinding block 71 or No. 2 grinding block 72, thereby preventing them from affecting the grinding effect. At the same time, it blows away the burrs that fall onto the No. 1 mold 21 and No. 2 mold 22 below, preventing the burrs from getting stuck between the tubular mechanical parts and the No. 1 mold 21 or No. 2 mold 22 when the No. 1 mold 21 or No. 2 mold 22 is extruded, causing the surface of the tubular mechanical parts to have pits and affecting the appearance of the tubular mechanical parts.

[0052] Example 3:

[0053] This embodiment is based on the previous embodiment, but differs from the previous embodiment in that, specifically, please refer to... Figures 5-6 The air outlet 86 is tilted away from the clamping block 4.

[0054] The air outlet 86 is tilted away from the clamping block 4, so that the blown burrs or metal fragments will not fly towards the clamping block 4, thus preventing burrs or metal fragments from falling onto the workers' bodies.

[0055] Example 4:

[0056] This embodiment is based on the previous embodiment, but differs from the previous embodiment in that, specifically, please refer to... Figures 5-6 The air outlet is surrounded by a spiral cleaning pipe with a diameter of 86 and a diameter of 84.

[0057] The air outlet 86 is spirally arranged around the cleaning pipe 84. The high-pressure air blown out through the air outlet 86 will not blow vertically onto the first grinding block 71 or the second grinding block 72, but will blow out at an angle, maintaining a certain angle with the first grinding block 71 or the second grinding block 72 on the horizontal plane. Thus, the inclined gas will blow away the burrs or metal debris in the angle between the first grinding block 71 or the second grinding block 72 and the corresponding second mold 22 or the first mold 21, thereby preventing the high-pressure gas from being unable to blow away the burrs or metal debris in the angle.

[0058] Example 5:

[0059] This embodiment is based on the previous embodiment, but differs from the previous embodiment in that, specifically, please refer to... Figure 5 The end of mold 21 away from the fixed block 62 is stepped; the two end faces of the stepped shape of polishing block 71 are fixedly connected to the two end faces of mold 21; the materials of polishing block 71 and polishing block 72 are the same as those of mold 21.

[0060] The first grinding block 71 and the second grinding block 72 are made of the same material as the first mold 21, so that the first grinding block 71 and the second grinding block 72 have the same hardness as the first mold 21. At the same time, the first grinding block 71 is fixedly connected to one end of the stepped shape of the first mold 21. At this time, the first grinding block 71 is between the first mold 21 and the second mold 22. When the first mold 21 extrudes the tubular mechanical part, the first grinding block 71 will not come into contact with the tubular mechanical part, and there will be no situation where the first grinding block 71 comes into contact with the tubular mechanical part and also extrudes the tubular mechanical part, thus ensuring the effectiveness of this utility model.
