Description

Technical Field

[0001] The present invention relates to the technical field of cold heading machines, and specifically to a fully automatic feeding mechanism for a cold heading machine. Background Art

[0002] A bolt is a cylindrical threaded fastener used with a nut. It is a type of fastener consisting of two parts: a head and a screw rod (a cylinder with external threads). It needs to cooperate with a nut and is used to tightly connect two parts with through holes. A cold heading machine is a device that cuts and cold-extrudes various processed metal wire rods, enabling the wire rods to be cold headed and formed within a mold. It is used to process various standard and non-standard fasteners and auto parts and motorcycle parts.

[0003] In the prior art, a Chinese document with the patent number CN219211462U proposed an intermittent feeding device for a cold heading machine with linear feeding, including a feeding box, a feeding clamp, an anti-reverse clamp, a transmission mechanism, a feeding swing arm, a feeding clamp limiting mechanism, and an anti-reverse clamp limiting mechanism installed on the feeding box; the transmission mechanism includes a feeding cam, a front pressure control cam, a rear pressure control cam, and a sprocket that are sequentially sleeved on a transmission shaft. This intermittent feeding device for a cold heading machine with linear feeding can ensure the opening and closing of the feeding clamp for clamping and feeding the wire rod, and control the anti-reverse clamp to close when the feeding clamp returns, effectively preventing the feeding clamp from bringing back the material during the return journey, ensuring the feeding accuracy; through the feeding clamp limiting mechanism, the feeding clamp can be selectively limited or the limit can be cancelled, and through the anti-reverse clamp limiting mechanism, the anti-reverse clamp can be selectively limited or the limit can be cancelled to meet the requirements of intermittent feeding, thereby effectively improving the feeding accuracy and stability. However, in actual use, it still cannot be automatically adjusted according to the bar specifications to adapt to the feeding process of bars of different specifications. In the prior art, a Chinese patent document with the patent number CN208195560U proposed a feeding component for a cold heading machine, including a feeding frame and front and rear feeding wheel groups installed on the front of the feeding frame. The front feeding wheel group consists of a first and a second feeding wheel arranged up and down, and the rear feeding wheel group consists of a third and a fourth feeding wheel arranged up and down; several locally convex material blocking planes are provided on the front of the feeding frame, which are respectively arranged at the feeding end of the front feeding wheel group, in the middle of the front and rear feeding wheel groups, and at the discharging end of the rear feeding wheel group. This is convenient for adjusting the feeding length and achieving a high degree of uniformity in the feeding length each time. However, in actual use, when there are attached impurities on the surface of the raw material, it still passes through the cold heading machine for processing, which will cause the impurities to adhere to the surface of the raw material, and then cause the raw material to deform during processing due to the presence of impurities, resulting in poor processing effects. Therefore, the present application discloses a fully automatic feeding mechanism for a cold heading machine to reduce the influence of impurities on the cold heading process, improve the accuracy of the cold heading process, and ensure the stability and safety of the processing process.

[0015] (III) Beneficial effects Compared with the prior art, the present invention provides a fully automatic feeding mechanism for a cold heading machine, which has the following beneficial effects:

[0016] 1. For this fully automatic feeding mechanism of the cold heading machine, the driving rod is driven to rotate by an external driving source. When the driving rod rotates, the sliding block is driven to rotate synchronously. When the sliding block rotates, it can realize the up and down movement of the sliding block in the sliding rod while driving the sliding rod to rotate synchronously around the axis of the driving rod. When the sliding rod rotates, the rotating plate can be driven to rotate synchronously, thereby realizing the sliding of the driving sleeve on the lifting rod, and further driving the pushing plate to move synchronously with the driving sleeve while being able to slide on the lifting rod. Therefore, the cold heading raw material can be properly pushed and positioned during the processing, ensuring the stability and reliability during the operation. At the same time, the lifting movement of the pushing plate is realized through the cooperation of the lifting rod and the driving sleeve, ensuring the proper position of the raw material in the processing area, and further improving the production efficiency and processing quality of the cold heading machine.

[0017] 2. The fully automatic feeding mechanism of this cold heading machine moves synchronously under the movement of the sliding plate driven by the pushing plate. Under the guidance of the buffer spring by the elastic force of the sliding plate, the sliding plate always moves synchronously along the slope of the sliding slope. When the sliding plate moves to the lowest end of the sliding slope, that is, when the trigger rod contacts the limiting plate, due to the arc of the limiting plate being inclined to one side, the trigger rod moves along the axis of the third guiding rod to one side. When the trigger rod is at the highest point of the limiting plate, that is, when the distance between the first clamping block and the second clamping block is the largest, and at the same time when the trigger rod contacts the protruding plate on the limiting plate, the second clamping block approaches the first clamping block driven by the elastic force of the extrusion spring, that is, the distance between the first clamping block and the second clamping block decreases. At the same time, through the cooperation between the first deflector plate and the second deflector plate, the contact cylinder can adapt to cold heading raw materials with different angles and different shapes, further improving the applicable range of this feeding mechanism.

[0018] 3. For the fully automatic feeding mechanism of this cold heading machine, when the sliding plate slides towards the bottom of the sliding slope, it contacts the trigger groove opened on one side of the folding plate through the first clamping block, thereby causing the folding plate to move along the axis of the second guiding rod, and then enabling the cold heading raw material on the bearing plate to enter the clamping assembly for clamping. When the sliding plate slides towards the top of the sliding slope, the contact with the folding plate is limited. Under the guidance of the second guiding rod by the elastic force of the limiting spring, the folding plate is reset, thereby realizing the limitation of the cold heading raw material on the bearing plate, further improving the accuracy during the processing of the cold heading raw material and avoiding the low processing efficiency caused by the accumulation of a large amount of raw materials.

[0019] 4. For the fully automatic feeding mechanism of this cold heading machine, when the cold heading raw material enters the cleaning box, it first contacts a plurality of cleaning teeth. Due to the arc of the teeth of the cleaning teeth being inclined to one side, the impurities attached to the surface of the cold heading raw material are further removed and separated, further ensuring the cleanliness of the cold heading raw material before processing. At the same time, through a plurality of cleaning rollers rotatably connected to the connecting plate, the cold heading raw material removed by the cleaning teeth can be cleaned. At the same time, due to the inclined setting of the guiding groove, the impurities cleaned by the cleaning rollers can be centrally collected through the guiding groove. At the same time, due to the surface of the conveying roller having a plurality of protrusions, the cold heading raw material can vibrate before processing, so that the remaining impurities after cleaning are separated by vibration, further improving the cleaning effect on the surface of the cold heading raw material, thereby reducing the influence of the impurities on the surface of the cold heading raw material during cold heading processing and improving the processing effect.

[0020] 5. For the fully automatic feeding mechanism of this cold heading machine, when the cold heading raw material enters the conveying plate, under the guidance of the "V"-shaped guiding block, the cold heading raw material can be split when it enters the feeding box. By contacting the contact plate, the contact plate drives the lifting plate to rise in the guiding plate, avoiding the accumulation of a large amount of cold heading raw materials at the same position, thus affecting the efficiency of cold heading processing. At the same time, when the cold heading raw material enters the feeding box, the lifting plate falls to the bottom of the clamping plate under the action of gravity, and at the same time, it can limit the cold heading raw materials in the feeding box, reducing the risk of the cold heading raw materials breaking away during the processing, and further improving the safety of the cold heading machine during use.

The sliding plate 23 is slidably connected to the sliding slope 24. The sliding slope 24 is fixedly connected to the bottom of the inner wall of the feeding box 7, and the sliding slope 24 is inclined to one side; the clamping assembly further includes a clamping plate fixedly connected to the top of the sliding plate 23. One side of the clamping plate is fixedly connected to a first clamping block 36. One side of the first clamping block 36 is fixedly connected to a guide plate. One side of the first clamping block 36 is rotatably connected to a first deflecting plate 37. One side of the first deflecting plate 37 is rotatably connected to a group of second deflecting plates 38. One side of the second deflecting plate 38 is rotatably connected to multiple groups of contact cylinders 39. Multiple groups of contact grooves are formed on the surface of the contact cylinder 39. A second clamping block 40 is slidably connected to the other side of the clamping plate. The second clamping block 40 has the same structure as the first clamping block 36. A group of bearing plates 29 are fixedly connected to the inner wall of the feeding box 7. The bearing plates 29 are arranged at the same angle as the sliding slopes 24. A placing plate 32 is fixedly connected to the top of the bearing plate 29. A sliding groove is formed on one side of the placing plate 32. A folding plate 35 is slidably connected in the sliding groove. One end of the folding plate 35 is fixedly connected to a second guide rod 33. The other end of the second guide rod 33 is fixedly connected in the sliding groove on one side of the placing plate 32. The second guide rod 33 is a telescopic structure. A limiting spring 34 is fixedly sleeved on the second guide rod 33. One end of the limiting spring 34 is fixedly connected to one side of the placing plate 32, and the other end of the limiting spring 34 is fixedly connected to one side of the folding plate 35. A trigger groove adapted to the first clamping block 36 is formed on one side of the folding plate 35. One end of the bottom of the second clamping block 40 is fixedly connected to a third guide rod 41.

The limiting plate 30 and the folding plate 35 are at the same height position;The sliding plate 23 moves synchronously under the movement of the pushing plate 16. Under the guidance of the buffer spring 22 by the elastic force of the sliding plate 23, the sliding plate 23 always moves synchronously along the slope of the sliding slope 24. When the sliding plate 23 moves to the lowest end of the sliding slope 24, that is, when the trigger rod 43 contacts the limiting plate 30. Since the limiting plate 30 is an arc inclined to one side, the trigger rod 43 moves to one side along the axis of the third guiding rod 41. When the trigger rod 43 is at the highest point of the limiting plate 30, that is, when the distance between the first clamping block 36 and the second clamping block 40 is the largest. At the same time, when the trigger rod 43 contacts the raised plate 31 on the limiting plate 30, the second clamping block 40 separates from the first clamping block 36 under the driving of the elastic force of the compression spring 42, that is, the distance between the first clamping block 36 and the second clamping block 40 increases. At the same time, through the cooperation between the first deflecting plate 37 and the second deflecting plate 38, the contact cylinder 39 can adapt to cold heading raw materials of different angles and different shapes, further improving the applicable range of the feeding mechanism; by setting the bearing plate 29 at the same angle as the sliding slope 24, when the guide plate contacts the folding plate 35 and pushes the folding plate 35 to move, the cold heading raw materials can roll along the guide plate into the clamping assembly. When the trigger rod 43 separates from the limiting plate 30, the first clamping block 36 and the second clamping block 40 approach each other to complete the clamping of the cold heading raw materials. When the sliding plate 23 slides towards the top of the sliding slope 24, the sliding plate 23 can be separated from the folding plate 35. Thus, under the guidance of the second guiding rod 33 by the elastic force of the limiting spring 34, the folding plate 35 is reset, further realizing the limitation of the cold heading raw materials on the bearing plate 29, further improving the accuracy during the processing of the cold heading raw materials and avoiding the low processing efficiency caused by the accumulation of a large amount of raw materials.;

At the same time, through the plurality of cleaning rollers 48 rotatably connected to the connecting plate 47, the cold heading raw material removed by the cleaning teeth 46 can be cleaned. At the same time, due to the inclined arrangement of the guide grooves 49, the impurities cleaned by the cleaning roller 48 can be centrally collected through the guide grooves 49.

A guide plate 25 is fixedly connected to one side of the feeding box 7. The guide plate 25 is provided at one end of the conveying plate 6. A chute is provided on one side of the guide plate 25, and a lifting plate 27 is slidably connected in the chute. A clamping plate 26 is fixedly connected to one side of the lifting plate 27. The clamping plate 26 is adapted to the chute. A contact plate 28 is fixedly connected to one side of the lifting plate 27. The contact plate 28 is a semi-circular structure bent to one side, and the bottom of the contact plate 28 contacts the cold heading raw material; when the cold heading raw material enters the conveying plate 6, under the guidance of the "V" shape of the guide block 20, the cold heading raw material can be split when entering the feeding box 7. By contacting the contact plate 28, the contact plate 28 drives the lifting plate 27 to rise in the guide plate 25, avoiding a large amount of cold heading raw materials from accumulating at the same position, thus affecting the efficiency of cold heading processing. At the same time, when the cold heading raw material enters the feeding box 7, the lifting plate 27 falls under the action of gravity to the bottom of the clamping plate 26, and at the same time, the cold heading raw material in the feeding box 7 can be limited, reducing the risk of the cold heading raw material breaking away during the processing, and further improving the safety of the cold heading machine during use.
