Description

Technical Field

[0001] This disclosure relates to the field of feeding equipment technology, and in particular to a feeding device for a multi-station cold heading machine. Background Technology

[0002] The feeding mechanism of a cold heading machine is an auxiliary device used in the bolt processing process to feed raw materials such as bars to facilitate their processing.

[0003] Currently, the mainstream feeding mechanism in the market is the feed wheel clamping drive, such as... Figure 1 As shown. This method is prone to slippage and poor precision when the equipment is running at high speed. Furthermore, it typically uses a servo motor to control the feeding length, which has poor reliability, is easily damaged, and has high maintenance costs. Additionally, when dealing with steel wire materials of different diameters, the entire feeding wheel needs to be replaced, making the operation complex and impacting production efficiency.

Detailed Implementation

[0050] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0051] According to one embodiment of this disclosure, this application provides a feeding device for a multi-station cold heading machine, such as... Figure 2-3As shown, the feeding device of the multi-station cold heading machine includes: a first drive mechanism with a rotatable first output end; a clamping mechanism connected to the first output end, configured to be driven by the first drive mechanism to clamp or release material; and a linear drive assembly with a reciprocating linearly movable second output end connected to the clamping mechanism for synchronously driving the clamping mechanism to reciprocate linearly. In this embodiment, the first output end of the first drive mechanism rotates to drive the clamping mechanism to clamp or release material, and the second output end of the linear drive assembly synchronously drives the clamping mechanism to reciprocate linearly. When the clamping mechanism is clamping material, the linear drive assembly moves the material in the feeding direction. This material clamping and moving method has a simple structure and prevents slippage during transport. The linear drive assembly can precisely control the moving distance, resulting in high material feeding accuracy and improved production efficiency.

[0052] like Figure 4-9 As shown, the first driving mechanism is a clamp motor 5, which has a rotatable clamp shaft 4 (i.e., the first output end). The caliper mechanism 6 includes a clamp 12, a clamp lever 13, a jaw 14, and an elastic element. The clamp 12 consists of two clamping parts, designated as a first clamping part 121 and a second clamping part 122, respectively. Both clamping parts are rotatably connected to the second output end of the linear drive assembly and are synchronously driven by the second output end to perform reciprocating linear movement. The clamp lever 13 is located between the first clamp 121 and the second clamping part 122. The clamp lever 13 is connected to the first output end of the clamp motor 5. When the first output end rotates, it synchronously drives the clamp lever to swing clockwise or counterclockwise, thereby driving the clamp to open / close. When the clamp motor 5 is working, the first output end rotates counterclockwise or clockwise, so the clamp lever 13 connected to the first output end is synchronously driven by the first output end to swing clockwise or counterclockwise, thereby driving the clamp 12 to open / close. At least two clamping mouths 14 are provided, and the clamping mouths 14 are detachably connected to the first clamping part 121 and the second clamping part 122 respectively. The clamping mouths 14 are synchronously driven to clamp or release the material when the clamping part 12 opens or closes. That is, when the clamping lever 13 rotates clockwise or counterclockwise, it synchronously drives the clamping part 12 to open (i.e., open) or close (i.e. close), and the clamping mouths 14 on the clamping part 12 open / close synchronously. The clamping mouths 14 are used to clamp the material, so the clamping mouths 14 clamp or release the material during the opening / closing process. The elastic element is a spring 15, which is located between the first clamping part 121 and the second clamping part 122. The spring is configured to generate elastic force on the first clamping part and the second clamping part to cooperate with the clamping lever to drive the clamp to open when it swings counterclockwise or clockwise.

[0053] Specifically, such as Figure 6-7As shown, the first clamping part 121 includes a first side 1211 and a second side 1212 that are perpendicularly connected, and a third connecting part 1213 that extends outward from the middle of the second side.

[0054] The second clamping portion 122 includes a third side 1221 and a fourth side 1222 that are perpendicularly connected, and a fourth connecting portion 1223 that extends outward from the middle of the fourth side 1222. The first clamping portion 121 and the second clamping portion 122 are generally L-shaped.

[0055] The third connecting part 1213 and the fourth connecting part 1223 are rotatably connected side by side to the second output end of the linear drive assembly, such that the first side 1211 and the third side 1221 are arranged in an up-down position, and the second side 1212 and the fourth side 1222 are arranged in an up-down position.

[0056] The clamp lever 13 is located between the first side and the third side, and its two ends are used to contact the first side and the third side, respectively. Figure 4-5 As shown, the clamp lever 13 is placed horizontally. The clamp lever 13 consists of three spaced-apart first connecting parts 131 with circular cross-sectional shapes and two connecting parts 132 with rectangular cross-sectional shapes connecting these three first connecting parts 131. The middle first connecting part 131 is longer and is fixedly connected to the end of the clamp shaft 4 of the clamp motor 5 (i.e., the first output end) via a coupling. Bearings 16 are fixed on the first connecting parts 131 at both ends.

[0057] The clamp lever 13 is positioned laterally between the first side 1211 of the first clamping part 121 and the third side 1221 of the second clamping part 122. The first side 1211 of the upper first clamping part 121 contacts the bearing 16 at one end of the clamp lever 13. Figure 4 As can be seen, the first side 1211 of the upper first clamping part 121 contacts the bearing 16 at the left end of the clamping lever 13, and the third side 1221 of the lower second clamping part 122 contacts the bearing 16 at the other end of the clamping lever 13. Figure 5 As can be seen, the third side 1221 of the lower second clamping part 122 contacts the bearing 16 at the right end of the clamping lever 13. The middle position of the second side 1212 of the first clamping part 121 and the middle position of the fourth side 1222 of the second clamping part 122 are rotatably connected to the second output end of the linear drive assembly. Specifically, as shown... Figure 6-7As shown, a third connecting portion 1213 extends outward from the middle of the second side 1212 of the first clamping portion 121. The third connecting portion 1213 has a mounting hole, allowing the first clamping portion 121 to be rotatably mounted on the second output end of the linear drive assembly through the mounting hole in the third connecting portion 1213. Correspondingly, a fourth connecting portion 1223 extends outward from the middle of the fourth side 1222 of the second clamping portion 122. The fourth connecting portion 1223 also has a mounting hole, allowing the second clamping portion 122 to be rotatably mounted on the second output end of the linear drive assembly through the mounting hole in the fourth connecting portion 1223. The third connecting portion 1213 and the fourth connecting portion 1223 are rotatably mounted side-by-side on the second output end, such that the first side 1211 and the third side 1221 of the two clamping portions are positioned vertically, and the second side 1212 and the fourth side 1222 are also positioned vertically. Figure 4-5 As shown, the first side 1211 of the first clamping part and the third side 1221 of the second clamping part are arranged vertically opposite each other, and the second side 1212 of the first clamping part and the fourth side 1222 of the second clamping part are arranged vertically opposite each other.

[0058] Spring 15 is disposed between two L-shaped clamping parts. Specifically, spring 15 is disposed near the edge of the second side 1212 of the first clamping part 121. Spring 15 is disposed away from the clamping lever, such that one end of spring 15 is fixedly connected to the second side 1212 of the first clamping part 121, and the other end of spring 15 is fixedly connected to the fourth side 1222 of the second clamping part 122.

[0059] When the clamp lever 13 rotates clockwise, the bearing at one end of the clamp lever 13 pushes upward the first side 1211 of the upper first clamping part 121, while the bearing at the other end of the clamp lever 13 pushes downward the third side 1221 of the lower second clamping part 122, causing the two clamping parts to close, i.e., the clamps 12 are in the closed state. At this time, the spring 15 between the two clamping parts is in a compressed state. Figure 8 As shown, the clamp lever 13 is in a slightly tilted state, the spring 15 on the clamp 12 is in a compressed state, the clamp 12 is closed, the jaw 14 on the clamp is closed, and the material is clamped.

[0060] When the clamp lever 13 is driven by the clamp motor 5 to rotate counterclockwise to its initial position (horizontal state), the bearings 16 at both ends of the clamp lever 13 release the pressure on the first and third sides of the upper and lower clamping parts. Under the action of its rebound force, the spring 15 between the two clamping parts drives the two clamping parts to open. At this time, the clamp 12 is in the open state. Figure 9As shown, the clamp lever 13 is in a horizontal state at this time. The bearings at both ends of the clamp lever 13 do not exert pressure on the first / third sides of the upper and lower clamping parts. Under the action of the spring, the two clamping parts are driven to open and release the material. This is the complete opening and closing process of the clamp 12. It should be noted that the contact surface between the L-shaped clamping part and the clamp lever 13 is always the bearing 16. When the second output end of the linear drive assembly synchronously drives the clamp 12 of the caliper mechanism 6 to reciprocate linearly, the clamp lever 13 is in a stationary state. Due to the sufficiently long structure of its L-shaped plate, the L-shaped clamping part always keeps the clamp lever in contact with it. The first and third sides of the upper and lower clamping parts reciprocate linearly along the bearing 16 of the clamp lever 13.

[0061] Combination Figure 4-5 As we can see, the clamp 12 is constructed in a manner similar to a scissor structure, with the fulcrum of the clamp's rotation being the point of rotational connection between it and the second output end.

[0062] Furthermore, the clamping jaws 14 are provided in two, respectively detachably connected to the edges of the second side 1212 and the fourth side 1222 of the first clamp 121 and the second clamping part 122, as shown below. Figure 6 As shown, the lower jaw 14 has a clamping opening 141, and the upper jaw 14 has a protrusion 142 at a corresponding position. The protrusion 142 cooperates with the clamping opening 141 to clamp materials. The clamping opening 141 is trapezoidal in shape. The jaw 14 and the clamp 12 are detachably connected. For example, the jaw 14 is detachably connected to the two clamping parts of the clamp by screws. When the material to be conveyed is larger than the clamping range of the jaw 14, the material can be conveyed by replacing the corresponding jaw 12. The entire replacement process only requires the removal of two screws and is quick and easy.

[0063] Furthermore, to ensure smooth rotation of the clamping part on the second output end of the linear drive assembly, first bushings 123 are respectively provided on the mounting holes of the third connecting part 1213 and the fourth connecting part 1223. A shallow groove 111 for mounting the first bushings 123 is provided on the second output end. The two first bushings 123 are sleeved and fixed on the second output end and located in the shallow groove 111. The shallow groove 111 serves to limit the movement of the first bushings 123. The third connecting part 1213 and the fourth connecting part 1223 are rotatably connected to the first bushings 123 through the mounting holes. When the second output end performs linear reciprocating movement, the clamp 12 located in the shallow groove 111 can move synchronously with the second output end.

[0064] In one embodiment, such as Figure 2-3As shown, the linear drive assembly includes a feeding motor 7, a gear 9, a rack and pinion feeding slider 10, and a feeding rod 11. The feeding motor 7 has a rotatable output shaft (i.e., a feeding shaft 8), and the gear is fixedly connected to the end of the output shaft (feeding shaft 8), and is synchronously driven to rotate by the output shaft of the feeding motor. The upper surface of the rack and pinion feeding slider 10 is provided with a rack 101 that meshes with the gear 9, and the side of the rack and pinion feeding slider 10 is slidably connected to a slide rail, as shown. Figure 3 As shown, slide rails 102 are slidably connected to the front and rear sides of the rack feeding slider 10, respectively. These slide rails 102 are fixed to the support plate 3, which is fixed to the chassis base 1. When the gear 9 rotates counterclockwise or clockwise, it drives the meshing rack 101 to reciprocate linearly. The feeding rod 11 serves as the second output end of the linear drive assembly; one end is fixedly connected to the rack feeding slider 10, and the other end is connected to the clamping mechanism, specifically, the clamp 12 of the clamping mechanism 6. Specifically, as... Figure 4-5 As shown, the other end of the feeding rod 11 is connected to the mounting holes of the third connecting part 1213 and the fourth connecting part 1223 of the clamp 12, so that the clamp 12 can rotate around the feeding rod 11 while being synchronously driven by the feeding rod 11 to perform reciprocating linear movement. This application can realize the reciprocating linear movement of the feeding rod 11 through the feeding motor 7, gear 9 and rack and pinion feeding slider 10. The feeding motor 7 can precisely control the rotation speed and number of revolutions, thereby controlling the linear movement distance of the feeding rod 11, and thus controlling the material transmission position of the clamp mechanism 6 with high precision.

[0065] When the feeding device of the multi-station cold heading machine of this application is feeding material, the clamp motor 5 rotates clockwise at a certain angle to make the clamp mechanism 6 clamp the material. At this time, the feeding motor 7 rotates clockwise to drive the gear 9 to drive the rack feeding slider 10 to slide a specified distance in the feeding direction, so that the feeding rod 11, which is fixedly connected to the rack feeding slider 10, also moves linearly and moves a specified distance, driving the clamp mechanism to move in the feeding direction while clamping the material, thereby realizing feeding.

[0066] In one embodiment, the rotation of gear 9 driven by the feeding motor 7 is converted into the reciprocating linear movement of the rack and pinion feeding slider 10. This conversion from rotation to reciprocating linear movement can also be replaced by the following method: Specifically, the linear drive assembly includes a linear drive mechanism and a feeding rod. The linear drive mechanism has a third output end capable of reciprocating linear movement, and the two ends of the feeding rod are respectively connected to the third output end and the caliper mechanism. The linear drive mechanism includes, but is not limited to, a slide module, a cylinder, a linear guide mechanism, and a lead screw guide mechanism.

[0067] In one embodiment, to centrally house the first drive mechanism, caliper mechanism, and linear drive assembly, the spatial structure of the device is described, such as... Figure 2-3As shown, the feeding device of the multi-station cold heading machine of this application also includes a chassis base 1, baffles 2, and support plates 3. The first drive mechanism and linear drive assembly are mounted on the chassis base 1; the baffles 2 and support plates 3 are fixedly mounted on the surface of the chassis base 1. Several baffles 2 are provided, arranged at intervals along the material feeding direction, such as... Figure 2 As shown, several baffles 2 are provided, and each baffle has a first opening 21 at a corresponding position. The center line of the first opening 21 is on the same straight line as the center line of the clamp 14. The first opening 21 is used to support the material. When the material is placed in the first opening 21, the clamp 14 should be able to just hold the material. Figure 10 As shown. Two support plates 3 are provided, which are mounted on the chassis base 1. These two support plates 3 are respectively located at the positions of the first drive mechanism (clamp motor 5) and the feed motor 7 of the linear drive assembly. The support plate 3 located at the first drive mechanism position has a second opening, and a second bushing 17 is fixed in the second opening. The first connecting part 131 of the clamp swing arm 13 located in the middle passes through the second bushing 17 and is connected to the end of the clamp shaft 4 of the clamp motor 5 through a coupling. The support plate 3 located at the feed motor 7 also has an opening, and a bearing is installed in the opening. The output shaft of the feed motor 7 passes through the bearing and is connected to the gear 9.
