Description

Technical Field

[0001] This invention relates to the field of double-ended stud processing technology, specifically to a discharge device for thread rolling of double-ended studs. Background Technology

[0002] Double-ended studs are cylindrical fasteners with threads at both ends. They are widely used in power, chemical, oil refining, valve, railway, bridge, steel structure, automotive parts, machinery, boiler steel structures, cranes, large-span steel structures, and large buildings. Double-ended studs are generally used to connect large parts; one end is screwed into the main body, and the other end is installed in an accessory that needs to be frequently disassembled. The manufacturing process of double-ended studs can be roughly divided into steps such as drawing, cutting, heating, forging, turning, and thread rolling.

[0003] Currently, in the machining of double-ended studs, thread rolling machines or thread lathes are commonly used to form the surface threads. The processing principle of a thread rolling machine is to form the thread groove by cold pressing. Compared with a thread lathe, it not only has higher processing efficiency, but also produces higher quality threads on the finished studs through extrusion forming. In some small processing workshops, it is necessary to manually add the machined double-ended studs into the thread rolling channel of the thread rolling machine. The thread rolling channel moves by reciprocating cold pressing. When adding double-ended studs, the hands are too close to the thread rolling channel, posing a certain safety hazard. In addition, to ensure that the thread formed by the double-ended studs after passing through the thread rolling channel is sufficiently standard, the double-ended studs must be kept vertical when entering the thread rolling channel. However, manual addition is difficult and poses a significant safety risk, making it difficult to maintain a vertical position throughout the process of the double-ended studs entering the thread rolling channel. The accuracy needs to be improved. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a discharge device for double-ended stud thread rolling, which solves the current problems.

A rotatably mounted movable baffle is mounted on the side of the fixed seat near the fixed baffle. An arc-shaped groove one is opened on the side of the fixed seat near the movable baffle, and an arc-shaped groove two is opened on the side of the movable baffle near the fixed baffle. The double-ended studs are clamped between the arc-shaped groove one and the arc-shaped groove two. A push plate is slidably mounted between the fixed baffle and the movable baffle. The push plate is connected to a pushing mechanism mounted on the top of the mounting base plate. The opposite sides of the fixed baffle and the movable baffle are both designed with an inclination.

[0006] As a preferred embodiment of the present invention, the sliding mounting plate is embedded with a sliding thread rolling plate on the side near the fixed thread rolling plate, and the side of the fixed thread rolling plate near the sliding thread rolling plate and the side of the fixed seat near the sliding thread rolling plate are located on the same vertical plane.

[0007] As a preferred embodiment of the present invention, a bearing plate is fixedly installed on the side of the fixed base near the fixed thread rolling plate, and an L-shaped groove is opened on the side of the bearing plate near the fixed thread rolling plate. The movable baffle is rotatably connected in the L-shaped groove, and the side of the movable baffle near the L-shaped groove is arc-shaped. Reset springs symmetrically distributed vertically are fixedly installed between the movable baffle and the side of the L-shaped groove.

[0008] As a preferred embodiment of the present invention, the inner side of the movable baffle is provided with a through groove designed to run from top to bottom, and a support column is rotatably inserted into the inner side of the through groove, the bottom end of the support column being fixedly connected to the bottom surface of the L-shaped groove.

[0009] As a preferred embodiment of the present invention, the side of the fixed baffle is provided with a fastening groove, and a U-shaped plate is fixedly installed on the top of the fixed baffle. A guide tube is welded to the top edge of the U-shaped plate. The guide tube is a cylindrical steel pipe with a through-hole design. The guide tube is located directly above the double-ended stud and matches the size of the double-ended stud.

[0010] As a preferred embodiment of the present invention, the top of the fixed baffle is provided with a top groove, the inner side of the top groove is threaded with a top screw, the top of the top screw extends through the inner side of the U-shaped plate to the top of the U-shaped plate, and the outer side of the top screw is threaded with a fastening nut that fits tightly with the top of the U-shaped plate.

[0011] As a preferred embodiment of the present invention, the pushing mechanism includes a drive seat, a limiting groove is formed on the inner side of the drive seat, a limiting plate is slidably connected to the inner side of the limiting groove, a guide groove communicating with the limiting groove is formed on the side of the drive seat near the push plate, the push plate is slidably connected to the inner side of the guide groove and fixedly connected to the limiting plate, a rotating wheel is rotatably installed on the inner side of the limiting groove and on the side of the limiting plate away from the push plate, an eccentric column is fixedly installed at the eccentric part of the rotating wheel, one end of a connecting rod is rotatably connected to the outer side of the eccentric column, and the other end of the connecting rod is rotatably connected to the side of the limiting plate.

[0012] As a preferred embodiment of the present invention, a rear baffle is fixedly installed on the top of the mounting base plate, the side of the drive seat is fixedly connected to the rear baffle, a drive motor is fixedly installed on the inner side of the drive seat, and the output end of the drive motor extends into the limiting groove and is fixedly connected to the center of the rotating wheel.

[0013] As a preferred embodiment of the present invention, the side of the bearing plate is provided with a threaded groove, and an adjusting screw is threadedly connected to the inner side of the threaded groove. One end of the adjusting screw passes through the threaded groove and is rotatably connected to the side of the movable baffle, and the other end of the adjusting screw passes through the fixed seat and extends to the outside of the fixed seat.

[0014] Compared with the prior art, the present invention provides a discharge device for double-ended stud thread rolling, which has the following beneficial effects:

[0015] 1. This discharge device for double-ended stud thread rolling uses a push plate to contact and push the double-ended stud, which in turn causes the movable baffle to rotate. This increases the space between arc groove one and arc groove two, allowing the double-ended stud to detach from arc groove one and arc groove two and vertically enter the thread rolling channel under the push of the push plate. The operator can place the double-ended stud into the guide tube in advance. After the previous double-ended stud located between arc groove one and arc groove two is pushed into the thread rolling channel by the push plate, the push plate and movable baffle reset, and the next double-ended stud will automatically fall into the space between arc groove one and arc groove two. This improves the safety of the thread rolling operation and further enhances the continuity of double-ended stud discharge.

[0016] 2. The discharge device for double-ended stud thread rolling uses the rotation of the rotating wheel to drive the eccentric column to make eccentric motion, which in turn pushes the push plate to make reciprocating motion in the guide groove through the connecting rod. At the same time, the limiting plate also makes reciprocating motion in the limiting groove, so as to realize the continuous pushing of the double-ended stud by the push plate and ensure the continuity of the thread rolling operation. At the same time, the limiting groove restricts the movement distance of the limiting plate, thereby limiting the movement distance of the push plate and preventing the movement distance of the push plate from being too long and affecting the smooth entry of the double-ended stud into the thread rolling channel.

[0017] 3. The discharge device for double-ended stud thread rolling can rotate the adjusting screw within the thread groove and push the movable baffle to rotate, thereby adjusting the initial position of the movable baffle and fine-tuning the space between arc groove one and arc groove two. This allows the device to clamp and push double-ended studs of different sizes, improving its applicability in double-ended stud thread rolling. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] Example 1

[0029] Please see Figure 1-8In this embodiment: the discharge device for double-ended stud thread rolling includes a mounting base plate 1 and a double-ended stud 14 mounted on the mounting base plate 1. A sliding mounting plate 2 is provided on the side of the mounting base plate 1, and a fixed thread rolling support plate 5 is mounted on the top of the mounting base plate 1. A thread rolling channel is formed between the fixed thread rolling support plate 5 and the sliding mounting plate 2. A fixed baffle 9 of the same size is fixedly mounted on the side of the fixed thread rolling support plate 5. A fixed seat 6 is fixedly mounted on the top of the mounting base plate 1. The fixed seat 6 is close to the fixed baffle 9. A movable baffle 11 with a rotating configuration is installed on the side. An arc-shaped groove 93 is opened on the side of the fixed base 6 near the movable baffle 11. An arc-shaped groove 113 is opened on the side of the movable baffle 11 near the fixed baffle 9. A double-headed stud 14 is clamped between the arc-shaped groove 93 and the arc-shaped groove 113. A push plate 12 is slidably installed between the fixed baffle 9 and the movable baffle 11. The push plate 12 is connected to a push mechanism installed on the top of the mounting base plate 1. The opposite sides of the fixed baffle 9 and the movable baffle 11 are both designed to be inclined.

[0030] The sliding mounting plate 2 is installed on the external thread rolling machine. The double-ended stud 14 is placed from top to bottom between the first arc groove 93 and the second arc groove 113. The double-ended stud 14 is clamped and enclosed by the first arc groove 93 and the second arc groove 113. A pushing mechanism drives the push plate 12 to move. The push plate 12 slides between the fixed baffle 9 and the movable baffle 11 and gradually approaches the double-ended stud 14. Then, the push plate 12 contacts and pushes the double-ended stud 14 to move, simultaneously causing the movable baffle 11 to rotate, thus causing the first arc groove 93 and the second arc groove 113 to... With the increased space between 13, the double-ended stud 14 can disengage from the arc groove 1 93 and the arc groove 2 113 and enter the thread rolling channel vertically under the push of the push plate 12. Under the coordinated movement of the sliding mounting plate 2 and the fixed thread rolling support plate 5 (this is the prior art), the thread rolling action of the double-ended stud 14 is realized. The inclined design of the fixed baffle 9 and the movable baffle 11 allows the double-ended stud 14 to enter the thread rolling channel at an angle relative to the fixed thread rolling support plate 5 in a vertical state, improving the smoothness of the double-ended stud 14 during feeding.

[0031] In a preferred embodiment, a sliding thread rolling plate 4 is embedded in the side of the sliding mounting plate 2 near the fixed thread rolling plate 5. The side of the fixed thread rolling plate 5 near the sliding thread rolling plate 4 and the side of the fixed base 6 near the sliding thread rolling plate 4 are on the same vertical plane, ensuring the smooth movement of the thread rolling channel and ensuring that the double-headed stud 14 remains vertical after entering the thread rolling channel. The sliding thread rolling plate 4 and the fixed thread rolling plate 5 are both provided with slots on opposite sides, and the two work together to realize the thread rolling action of the double-headed stud 14.

[0032] In a preferred embodiment, a support plate 10 is fixedly installed on the side of the fixed base 6 near the fixed thread rolling plate 5. An L-shaped groove 101 is formed on the side of the support plate 10 near the fixed thread rolling plate 5. A movable baffle 11 is rotatably connected within the L-shaped groove 101. The side of the movable baffle 11 near the L-shaped groove 101 has an arc-shaped design. Symmetrically distributed return springs 13 are fixedly installed between the movable baffle 11 and the side of the L-shaped groove 101. The push plate 12 pushes the double-headed stud 14 to move and disengage. During the process of leaving the arc groove 113 and the arc groove 213, the movable baffle 11 rotates in the L-shaped groove 101 and simultaneously compresses the return spring 13. When the double-ended stud 14 completely leaves the arc groove 113 and the arc groove 213 and enters the thread rolling channel, the movable baffle 11 will return to its original position under the action of the return spring 13, thereby limiting the next double-ended stud 14 placed in the arc groove 113 and the arc groove 213, and improving the continuity and smoothness of the thread rolling operation of the double-ended stud 14.

[0033] In a preferred embodiment, the inner side of the movable baffle 11 is provided with a through groove 111 designed to run from top to bottom. A support column 112 is rotatably inserted into the inner side of the through groove 111. The bottom end of the support column 112 is fixedly connected to the bottom surface of the L-shaped groove 101. The movable baffle 11 rotates around the support column 112 as the rotation axis, thereby improving the stability of the rotation of the movable baffle 11.

[0034] In a preferred embodiment, the side of the fixed baffle 9 is provided with a fastening groove 92. The fixed baffle 9 is installed on the side of the fixed thread rolling support plate 5 through the fastening groove 92, which facilitates installation and maintenance. A U-shaped plate 17 is fixedly installed on the top of the fixed baffle 9. A guide tube 16 is welded to the top edge of the U-shaped plate 17. The guide tube 16 is a cylindrical steel pipe with a through-hole design. The guide tube 16 is located directly above the double-ended stud 14 and matches the size of the double-ended stud 14. The operator puts the double-ended stud 14 into the guide tube 16 from top to bottom. The double-ended stud 14 will slide down the guide tube 16 into the arc groove 93. Between the arc-shaped groove 113 and the bottom of the double-ended stud 14, the bottom of the stud 14 contacts the bottom surface of the L-shaped groove 101. This allows the feeding position of the double-ended stud 14 to be far away from the thread rolling channel. The operator can place the double-ended stud 14 into the guide tube 16 in advance. After the previous double-ended stud 14, located between the arc-shaped groove 93 and the arc-shaped groove 113, is pushed into the thread rolling channel by the push plate 12, the push plate 12 and the movable baffle 11 reset, and the next double-ended stud 14 automatically falls into the space between the arc-shaped groove 93 and the arc-shaped groove 113. This improves the safety of the thread rolling operation and further enhances the continuity of the double-ended stud 14's output. Alternatively, a conveying device (existing technology) can be installed above the guide tube 16 to vertically convey the double-ended stud 14. When the double-ended stud 14 moves vertically to directly above the guide tube 16, the conveying device releases the double-ended stud 14 downwards, simplifying operation.

[0035] Example 2

[0036] Please see Figure 1-8 In this embodiment: As a preferred embodiment, the top of the fixed baffle 9 is provided with a top groove 91, and the inner side of the top groove 91 is threaded with a top screw 171. The top of the top screw 171 extends through the inner side of the U-shaped plate 17 to the top of the U-shaped plate 17. The outer side of the top screw 171 is threaded with a fastening nut 172 that fits tightly with the top of the U-shaped plate 17. Through the cooperation of the top screw 171 and the fastening nut 172, the U-shaped plate 17 is fixed on the top of the fixed baffle 9, thereby fixing the position of the guide tube 16 and ensuring the stability of the feeding of the double-headed stud 14.

[0037] In a preferred embodiment, the driving mechanism includes a drive seat 7. A limiting groove 71 is formed on the inner side of the drive seat 7. A limiting plate 8 is slidably connected to the inner side of the limiting groove 71. A guide groove 72 communicating with the limiting groove 71 is formed on the side of the drive seat 7 near the push plate 12. The push plate 12 is slidably connected to the inner side of the guide groove 72 and fixedly connected to the limiting plate 8. A rotating wheel 73 is rotatably mounted on the inner side of the limiting groove 71 and on the side of the limiting plate 8 away from the push plate 12. An eccentric column 74 is fixedly mounted at the eccentric part of the rotating wheel 73. One end of a connecting rod 75 is rotatably connected to the outer side of the eccentric column 74. The other end of the connecting rod 75 is rotatably connected to the side of the limiting plate 8. The rotation of the rotating wheel 73 drives the eccentric column 74 to make eccentric movements, which in turn pushes the push plate 12 to reciprocate in the guide groove 72 through the connecting rod 75. At the same time, the limiting plate 8 also makes reciprocating movements in the limiting groove 71, so as to realize the continuous pushing of the double-headed stud 14 by the push plate 12, ensuring the continuity of the thread rolling operation. At the same time, the limiting groove 71 restricts the movement distance of the limiting plate 8, thereby limiting the movement distance of the push plate 12, preventing the movement distance of the push plate 12 from being too long and affecting the smooth entry of the double-headed stud 14 into the thread rolling channel.

[0038] In a preferred embodiment, a rear baffle 3 is fixedly installed on the top of the mounting base plate 1, the side of the drive seat 7 is fixedly connected to the rear baffle 3, a drive motor is fixedly installed on the inner side of the drive seat 7, and the output end of the drive motor extends into the limiting groove 71 and is fixedly connected to the center of the rotating wheel 73. By starting the drive motor, the rotating wheel 73 is driven to rotate, thereby ensuring that the push plate 12 performs a continuous reciprocating pushing action.

[0039] Example 3

[0040] Please see Figure 1-8In this embodiment: a threaded groove 102 is provided on the side of the bearing plate 10, and an adjusting screw 15 is threadedly connected to the inner side of the threaded groove 102. One end of the adjusting screw 15 passes through the threaded groove 102 and is rotatably connected to the side of the movable baffle 11. The other end of the adjusting screw 15 passes through the fixed seat 6 and extends to the outside of the fixed seat 6. By rotating the adjusting screw 15, the adjusting screw 15 can rotate in the threaded groove 102 and push the movable baffle 11 to rotate, thereby adjusting the initial position of the movable baffle 11, and then fine-tuning the space between the arc groove 113 and the arc groove 113. This allows the equipment to clamp and push double-headed studs 14 of different sizes, improving the applicability of the equipment in the thread rolling operation of double-headed studs 14.

[0041] The working principle and usage process of this invention are as follows: The operator places the double-ended stud 14 into the guide tube 16 from top to bottom. The double-ended stud 14 slides down the guide tube 16 into the space between the first arc groove 93 and the second arc groove 113. The drive motor is started, causing the rotating wheel 73 to rotate. The rotation of the rotating wheel 73 causes the eccentric column 74 to move eccentrically, which in turn pushes the push plate 12 to reciprocate within the guide groove 72 via the connecting rod 75. Simultaneously, the limiting plate 8 also reciprocates within the limiting groove 71, achieving continuous pushing of the double-ended stud 14 by the push plate 12. The push plate 12 slides between the fixed baffle 9 and the movable baffle 11, gradually approaching the double-ended stud 14. Then, the push plate 12 contacts and pushes the double-ended stud 14 to move, simultaneously driving... The movable baffle 11 rotates, increasing the space between arc groove 1 (93) and arc groove 2 (113). The double-headed stud 14 is then disengaged from arc groove 1 (93) and arc groove 2 (113) and vertically enters the thread rolling channel under the push of the push plate 12. With the coordinated movement of the sliding mounting plate 2 and the fixed thread rolling support plate 5, the thread rolling action of the double-headed stud 14 is realized. After the previous double-headed stud 14 located between arc groove 1 (93) and arc groove 2 (113) is pushed into the thread rolling channel by the push plate 12, the push plate 12 and the movable baffle 11 reset. The next double-headed stud 14 will automatically fall into the space between arc groove 1 (93) and arc groove 2 (113). This improves the safety of the thread rolling operation and further enhances the continuity of the double-headed stud 14's output.
