Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of cold heading machine technology, and more specifically, to a cold heading machine for bolt production. Background Technology

[0002] In the history of bolt production, traditional processing methods such as cutting have dominated. This method obtains the final shape of the bolt by removing the blank material. The bar stock is turned using equipment such as a lathe to cut off the excess material to form the shank and head shape of the bolt. However, this processing method has many drawbacks.

[0003] According to a public disclosure (publication number: CN216027882U), a cold heading machine for bolt production includes a left fixed plate. A sleeve block is fixedly connected to the right side of the left fixed plate, and a sleeve ring is fixedly connected to the side of the sleeve block. A mold plate is fixedly connected to the right side of the sleeve block, and a push rod is fixedly connected to the middle of the right side of the mold plate. In this cold heading machine, a connecting plate is fixedly connected to the side of the sleeve ring, and sliding blocks at corresponding positions on the top and bottom of the sliding plate are slidably connected to the inner side of the sliding groove. The left side of the sliding block resists the tail end of the thrust spring. Therefore, during processing, the inner side of the spiral head is engaged with the side of the push rod, while the outer side of the spiral head is movably connected to the inner side of the sleeve hole. During removal, the thrust spring unfolds and pushes the sliding plate, causing the sliding plate to move the spiral head away from the push rod.

[0004] In the aforementioned application, when the bolt processing is completed, the workers need to manually remove it, and then it needs to be removed according to the specifications, which is time-consuming and labor-intensive and needs to be improved. Therefore, we propose a cold heading machine for bolt production. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a cold heading machine for bolt production, which solves the problem in the related art that when the bolt processing is completed, workers need to manually remove it and then stack it according to specifications, which is time-consuming and labor-intensive.

[0006] According to one aspect, at least one embodiment of this disclosure provides a cold heading machine for bolt production, including a base, a body fixedly connected to the top of the base, a conveying assembly disposed inside the body, a processing assembly disposed on the top of the inner wall of the body, a feeding plate fixedly connected to the inner side wall of the body, and a quantitative discharge mechanism disposed on the side of the body.

[0007] The quantitative discharge mechanism includes a collection box, which is located on the side of the machine body. A motor is fixedly installed on the rear side of the collection box. A reciprocating lead screw is fixedly connected to the end of the output shaft of the motor. A reciprocating threaded sleeve is threaded to the circumferential surface of the reciprocating lead screw. A connecting block is fixedly connected to the bottom of the reciprocating threaded sleeve. A push plate is fixedly connected to the bottom of the connecting block. A limit rod is fixedly connected to the inner side wall of the collection box. A discharge trough is opened on the front side of the collection box.

[0008] For example, in a cold heading machine for bolt production provided in at least one embodiment of this disclosure, the following is also included: a sliding groove is provided on the side of the feeding plate, a fixing plate is fixedly connected to the top of the reciprocating threaded sleeve, and a limiting plate is fixedly connected to the side of the fixing plate. The design of the limiting plate is advantageous because when the limiting plate slides, the bolt enters the interior of the collection box through the feeding plate.

[0009] The side section of the reciprocating threaded sleeve is set to a rectangle, and the reciprocating threaded sleeve is slidably connected to the circumferential surface of the limiting rod. The above design is conducive to making the reciprocating threaded sleeve perform linear reciprocating motion.

[0010] The side section of the fixed plate is L-shaped, and the limiting plate is slidably connected to the inner wall of the slide groove. This design is beneficial to the sliding of the limiting plate when the fixed plate moves.

[0011] The collection box is located below the feeding plate, and the push plate is in contact with the bottom of the inner wall of the collection box. When the push plate moves, it drives the bolts accumulated inside the collection box to move.

[0012] According to another aspect, at least one embodiment of this disclosure also provides a cold heading machine for bolt production, including a damage prevention mechanism provided at the bottom of the blanking plate. The damage prevention mechanism includes a rectangular plate, which is fixedly connected to the bottom of the blanking plate. A torsion spring rod is rotatably connected to the rear side of the rectangular plate. A sleeve is fixedly connected to the circumferential surface of the torsion spring rod, and a receiving plate is fixedly connected to the circumferential surface of the sleeve. The above design is beneficial to avoid bolt damage during the bolt falling process.

[0013] For example, in a cold heading machine for bolt production provided in at least one embodiment of this disclosure, a contact plate is fixedly connected to the bottom of the receiving plate, and a limit block is fixedly connected to the side of the base. The above design is beneficial to prevent the arc of the receiving plate from being too large when the receiving plate moves downward in an arc.

[0014] The number of rectangular plates is set to two, and they are symmetrical to each other along the vertical central axis of the bottom of the blanking plate. This design helps to enhance the stability of the torsion spring rod during rotation.

[0015] The limiting block is located on the movement trajectory of the contact plate, and the side cross-section of the limiting block is L-shaped. The above design is beneficial to blocking the movement of the contact plate.

[0016] The receiving plate is located at the bottom of the blanking plate, and the above design helps to protect the bolts.

[0017] The beneficial effects of the embodiments disclosed herein are as follows:

[0018] 1. In this utility model, the driving force of the motor drives the reciprocating screw, reciprocating sleeve, limit rod, connecting block, push plate, fixing plate, slide groove, limit plate, slide groove and other components to cooperate with each other, realize the start of the motor fixedly installed on the rear side of the collection box, thereby driving the reciprocating screw fixed at the end of the output shaft to rotate. The rotation of the reciprocating screw drives the reciprocating sleeve threaded to the circumferential surface to make linear reciprocating motion on the circumferential surface of the limit rod. When the reciprocating sleeve makes linear reciprocating motion, it drives the fixing plate fixed at the top to move. When the bolt processing is completed and the workers take it out, there is no need for the workers to take it out according to the specifications, which saves time and effort and is simple to operate.

[0019] 2. In this utility model, the rotational force of the torsion spring rod drives the rectangular plate, sleeve, receiving plate, contact plate, limiting block and other components to cooperate with each other. When the limiting plate moves, it no longer blocks the bolt from continuing to move, so that the bolt falls into the inside of the receiving plate through the feeding plate. When multiple bolts fall into the receiving plate, the torsion spring rod on the rear side of the rectangular plate rotates. The rotation of the torsion spring rod drives the sleeve fixed on the circumferential surface to rotate. The rotation of the sleeve drives the receiving plate fixed on the circumferential surface to move downward in an arc. When discharging bolts in a quantitative manner, damage to the bolts when they fall is avoided. Attached Figure Description

[0027] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0028] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0030] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-5 As shown, a cold heading machine for bolt production according to an embodiment of the present disclosure is shown, including a base 1, a body 2 fixedly connected to the top of the base 1, a conveying assembly 3 disposed inside the body 2, a processing assembly 4 disposed on the top of the inner wall of the body 2, a feeding plate 7 fixedly connected to the inner side wall of the body 2, and a quantitative discharge mechanism 5 disposed on the side of the body 2.

[0034] The quantitative discharge mechanism 5 includes a collection box 51, which is located on the side of the machine body 2. A motor 52 is fixedly installed on the rear side of the collection box 51. A reciprocating screw 53 is fixedly connected to the end of the output shaft of the motor 52. A reciprocating sleeve 54 is threadedly connected to the circumferential surface of the reciprocating screw 53. A connecting block 56 is fixedly connected to the bottom of the reciprocating sleeve 54. A push plate 57 is fixedly connected to the bottom of the connecting block 56. A limit rod 55 is fixedly connected to the inner side wall of the collection box 51. A discharge chute 511 is opened on the front side of the collection box 51.

[0035] In some examples, the following are also included: a groove 59 is provided on the side of the feed plate 7, a fixing plate 58 is fixedly connected to the top of the reciprocating thread sleeve 54, and a limiting plate 510 is fixedly connected to the side of the fixing plate 58. The design of the limiting plate 510 is advantageous so that when the limiting plate 510 slides, the bolt enters the interior of the collection box 51 through the feed plate 7.

[0036] The side section of the reciprocating threaded sleeve 54 is set to a rectangle. The reciprocating threaded sleeve 54 is slidably connected to the circumferential surface of the limiting rod 55. The above design is conducive to enabling the reciprocating threaded sleeve 54 to perform linear reciprocating motion.

[0037] The side section of the fixed plate 58 is set to L-shape, and the limiting plate 510 is slidably connected to the inner side wall of the slide groove 59. The above design is beneficial to drive the limiting plate 510 to slide when the fixed plate 58 moves.

[0038] The collection box 51 is located below the feeding plate 7. The push plate 57 is in contact with the bottom of the inner wall of the collection box 51. When the push plate 57 moves, it drives the bolts accumulated inside the collection box 51 to move.

[0039] For example, such as Figures 1-5As shown, when the worker removes the bolts from the processing assembly 4 and places them on top of the conveying assembly 3, the conveying assembly 3 conveys the bolts to the top of the unloading plate 7. After the bolts accumulate on the top of the unloading plate 7, the worker starts the motor 52 fixedly installed on the rear side of the collection box 51, thereby driving the reciprocating screw 53 fixed at the end of the output shaft to rotate. The rotation of the reciprocating screw 53 drives the reciprocating sleeve 54 threaded on the circumferential surface to perform linear reciprocating motion on the circumferential surface of the limit rod 55. When the reciprocating sleeve 54 performs linear reciprocating motion, it drives the fixed on the top... The fixed plate 58 moves, which in turn drives the limiting plate 510, which slides on the inner wall of the chute 59, to move. When the limiting plate 510 moves, it no longer blocks the movement of the bolt, allowing the bolt to enter the interior of the collection box 51. At this time, the reciprocating threaded sleeve 54 moves, which drives the connecting block 56, which is fixed at the bottom, to move. The connecting block 56 drives the push plate 57, which is fixed at the bottom, to slide against the inner wall of the collection box 51, thereby pushing the bolts accumulated inside the collection box 51 to move. As the push plate 57 moves, the bolts are released from the interior of the collection box 51 through the discharge chute 511 opened on the side of the collection box 51.

[0040] like Figures 1-5 As shown, it illustrates a cold heading machine for bolt production in another embodiment of this disclosure. The technical solution is largely the same as that of Embodiment 1, so only the differences are described. The anti-damage mechanism 6 is provided at the bottom of the feeding plate 7. The anti-damage mechanism 6 includes a rectangular plate 61, which is fixedly connected to the bottom of the feeding plate 7. A torsion spring rod 62 is rotatably connected to the rear side of the rectangular plate 61. A sleeve 63 is fixedly connected to the circumferential surface of the torsion spring rod 62. A receiving plate 64 is fixedly connected to the circumferential surface of the sleeve 63. The above design is beneficial to avoid bolt damage during the bolt falling process.

[0041] In some examples, the bottom of the receiving plate 64 is fixedly connected to a contact plate 65, and the side of the base 1 is fixedly connected to a limit block 66. The above design helps to prevent the receiving plate 64 from moving too far in an arc when it moves downward in an arc.

[0042] The number of rectangular plates 61 is set to two, and they are symmetrical to each other along the vertical central axis of the bottom of the blanking plate 7. The above design helps to enhance the stability of the torsion spring rod 62 during rotation.

[0043] The limiting block 66 is located on the movement trajectory of the contact plate 65. The side cross section of the limiting block 66 is L-shaped. The above design is beneficial to blocking the movement of the contact plate 65.

[0044] The receiving plate 64 is located at the bottom of the blanking plate 7, and the above design helps to protect the bolts.

[0045] For example, such as Figures 1-5As shown, when the limiting plate 510 moves, it no longer blocks the bolt from continuing to move, allowing the bolt to fall through the feeding plate 7 into the interior of the receiving plate 64. When multiple bolts fall onto the receiving plate 64, the torsion spring rod 62 on the rear side of the rectangular plate 61 rotates. The rotation of the torsion spring rod 62 drives the sleeve 63 fixed on the circumferential surface to rotate. The rotation of the sleeve 63 drives the receiving plate 64 fixed on the circumferential surface to move downward in an arc, thereby reducing the impact force of the bolts falling downward. When the receiving plate 64 moves downward in an arc, it drives the contact plate 65 fixed at the bottom to move downward in an arc. During the movement of the contact plate 65, it contacts the limiting block 66, thereby blocking the torsion spring rod 62 from continuing to move. At this time, the receiving plate 64 no longer moves. When the receiving plate 64 no longer moves, the spiral moves downward through the receiving plate 64 via the inclined plane and enters the interior of the collection box 51.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
