Description

Technical Field

[0002] In the field of bolt manufacturing, U-bolts are a common fastener widely used in various mechanical equipment and structures. Traditional U-bolt production methods are usually carried out manually or with simple mechanical equipment, which usually have problems such as low production efficiency, unstable product quality and complex operation. Especially in the key steps such as positioning, forming and blanking of steel wire, due to the intervention of human factors, it is difficult to ensure the consistency of product quality, which affects the overall performance of U-bolts.

[0003] Specifically, the production of U-bolts in the prior art usually includes multiple steps such as the preparation, forming and subsequent processing of steel wire. In the preparation stage of steel wire, the material needs to be straightened, cut and threaded, and these steps often require manual intervention, which is not only inefficient but also difficult to control in terms of precision. In the forming stage, traditional production equipment often cannot achieve precise positioning and forming, resulting in deviations in the shape and size of the U-bolt.

[0004] In order to solve the above problems, a variety of U-bolt production equipment with a high degree of automation have emerged in recent years. However, these equipment still have certain deficiencies in terms of precise positioning of steel wire, control of forming depth, and adjustment of the vertical state of both ends after forming. Specifically, inaccurate placement of steel wire may lead to large deviations in the size of the U-bolt after forming; improper control of the forming depth may affect the structural strength of the U-bolt; inaccurate adjustment of the vertical state of both ends after forming may not meet the process requirements.

[0034] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the invented product is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0036] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0037] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In the first aspect of this application, Figure 1 and Figure 2 As shown, a U-bolt production and forming mechanism is provided, including: a tool, including a first support block 1 and a second support block 2, a forming groove is provided between the two, the first support block 1 is provided with a first straight groove 101, the second support block 2 is provided with a second straight groove 201 coaxially aligned with the first straight groove 101, the first straight groove 101 and the second straight groove 201 are used to accurately position the steel wire material; a press 3, which can be raised and lowered in the forming groove, and when the press 3 is pressed down, it cooperates with the side walls of the two support blocks to press the steel wire material into a U-shaped structure; a pusher 4, which can be horizontally displaced on the side of the forming groove, and is used to push out the formed U-bolt and drop the material; a power unit, including a first drive device and a first transmission device, the first drive device provides driving force, and the first transmission device distributes power to the press and the pusher, so that the two can move in sequence according to the process flow.

[0039] Specifically, first, the steel wire is precisely placed in the first linear groove 101 and the second linear groove 201. The two linear grooves are coaxially aligned, providing a stable support and positioning for the steel wire, ensuring that it is in the correct processing position. Subsequently, the press 3 starts to press down under the drive of the power unit. During the pressing process of the press 3, it squeezes the steel wire within the range of the molding groove downward. Since the two ends of the steel wire are firmly supported by the first linear groove 101 and the second linear groove 201, the steel wire is bent under the action of the press, forming a U-shaped structure with a concave middle and upright at both ends. After the compression molding is completed, the pusher 4 moves horizontally under the drive of the power unit to push the formed U-shaped bolt out of the molding groove to achieve blanking.

[0040] In this embodiment, by using the coaxial alignment design of the first straight groove 101 and the second straight groove 201, accurate placement and positioning of the steel wire material is achieved, providing an accurate basis for subsequent forming processing; by utilizing the cooperation between the press 3 and the tooling, the steel wire material can be pressed into a U-shaped structure through a single downward pressing action, thereby improving production efficiency; the entire production process, from positioning, forming to blanking of the steel wire material, can be completed through automatic control of the power unit, reducing manual intervention and improving the degree of automation of production.

[0041] Optionally, a lower limit pad is provided in the forming groove. When the press 3 is pressed down, it will contact with the lower limit pad, playing a limiting role, ensuring that the press 3 stops after being pressed down to a certain position, thereby controlling the forming depth of the U-bolt; on the other hand, the lower limit pad can be used to ensure that the depth of each compression molding is consistent, thereby improving the accuracy and stability of the U-bolt forming structure; finally, the shape and material of the lower limit pad can also affect the shape of the bottom of the steel wire material, which helps to shape the bottom shape of the U-bolt that better meets the design requirements.

[0042] In some embodiments, the tooling includes a first support seat 5 and a second support seat 6, the first support seat 5 is rotatably connected to the first support block 1, and the second support seat 6 is rotatably connected to the second support block 2; when the press 3 is not pressed down, the first linear groove 101 and the second linear groove 201 remain in a horizontal coaxial state; when the press is pressed down, the first support block 1 and the second support block 2 are synchronously rotated toward each other by a predetermined angle through a linkage structure, so that the bending angle of the two sides of the steel wire material is less than 90 degrees, and then the press is retracted, and the two sides of the steel wire material naturally rebound to a vertical state. .

[0043] Specifically, before the press 3 is pressed down, the first support block 1 and the second support block 2 are rotationally connected through the first support seat 5 and the second support seat 6 respectively. At this time, the first straight groove 101 and the second straight groove 201 remain in a horizontal coaxial state, ready for the placement of the steel wire material; when the press 3 is pressed down, it begins to press the steel wire material into a U-shaped structure; then, the first support block 1 and the second support block 2 will rotate synchronously towards each other at a predetermined angle under the action of the linkage mechanism; due to the rotation of the support blocks, the two ends of the originally horizontal steel wire material will be bent into a vertical state, thereby completing the final shape of the U-shaped bolt.

[0044] When the press 3 is pressed down to a predetermined depth, the side edges of the steel wire material may not have reached the vertical state required by the process. At this time, the first support block 1 and the second support block 2 will rotate in conjunction, and they will squeeze the side edges of the steel wire material, causing it to gradually become vertical, thereby meeting the process requirements.

[0045] For example, when the press 3 is pressed down to a predetermined depth, the angle between the two ends of the steel wire is 20 degrees. By setting the rotation angle of each support block to 10 degrees, precise adjustment of the vertical state of the two ends of the steel wire can be achieved.

[0046] In this embodiment, by designing an ingenious linkage rotation mechanism, the rotation angle and speed of the support blocks can be accurately controlled, thereby achieving synchronous rotation of the support blocks and ensuring that both ends of the steel wire material can be evenly squeezed to a vertical state.

[0047] In some embodiments, the first support block 1 is provided with a first pressure block 102, and the first support seat 5 is provided with a first rebound pad 501, and the first rebound pad 501 supports and rebounds the first pressure block 102, thereby controlling the rotation angle of the first support block 1; the second support block 2 is provided with a second pressure block 202, and the second support seat 6 is provided with a second rebound pad 601, and the second rebound pad 601 supports and rebounds the second pressure block 202, thereby controlling the rotation angle of the second support block 2.

[0048] Specifically, when the first support block 1 or the second support block 2 rotates, the pressure block thereon will move accordingly. When the pressure block contacts the corresponding rebound pad, the rebound pad will elastically deform to the maximum extent. Due to the obstruction of the rebound pad, the rotation of the support block will stop. When the pressing is completed, the rebound pad restores its shape, thereby driving the first support block 1 or the second support block 2 to return to its position.

[0049] By adjusting the position and shape of the spacer block, the rotation angle of the support block can be accurately controlled to ensure that both ends of the steel wire material are squeezed to a proper vertical state.

[0050] In some embodiments, the first pressure block 102 and the second pressure block 202 are both located in the forming groove; when the press 3 presses down the steel wire material, the bottom of the steel wire material contacts and presses down the first pressure block 102 and the second pressure block 202, so that the first support block 1 and the second support block 2 rotate synchronously towards each other until the first pressure block 102 abuts against the first rebound pad 501, and the second pressure block 202 abuts against the second rebound pad 601.

[0051] Specifically, before starting, the first pressing block 102 and the second pressing block 202 are located in the molding groove and are in a standby state; when the press 3 starts to press the steel wire material, the bottom of the steel wire material will first contact the first pressing block 102 and the second pressing block 202 and press them downward; due to the connection between the pressing block and the support block, when the pressing block is pressed down, it will drive the first support block 1 and the second support block 2 to start synchronously rotating in opposite directions, and this rotation will continue until the first pressing block 102 abuts against the first rebound pad 501, and the second pressing block 202 abuts against the second rebound pad 601, ensuring that the support blocks do not rotate excessively. After reaching the travel limit, the compression molding process is completed, and the steel wire material is precisely molded into the shape of a U-bolt, and the sides at both ends reach the vertical state required by the process.

[0052] This embodiment designs an ingenious linkage structure, placing the first pressing block 102 and the second pressing block 202 in the molding groove, making the entire molding process more compact and efficient; using the pad as a stroke limiter ensures the consistency and accuracy of each molding, thereby improving product quality; integrating multiple steps in one molding groove simplifies the production process and improves production efficiency.

[0053] In some embodiments, a first roller 103 is provided on the side wall of the first support block 1 close to the forming groove, and a second roller 203 is provided on the side wall of the second support block 2 close to the forming groove; when the press 3 presses down the steel wire material, the first roller 103 and the second roller 203 act on the left and right sides of the steel wire material respectively, causing it to gradually bend into shape.

[0054] Specifically, when the press 3 presses down the steel wire, the steel wire begins to deform. At this time, the first roller 103 and the second roller 203 act on the left and right sides of the steel wire respectively. The design of the rollers reduces the friction between the steel wire and the steel wire, making the steel wire smoother during the bending process. At the same time, the rollers can roll along the sides of the steel wire, thereby guiding the steel wire to gradually bend into a predetermined shape. Under the joint action of the rollers and the press, the steel wire is finally bent into the shape of a U-bolt, and the sides at both ends reach the vertical state required by the process.

[0055] In some embodiments, the pusher includes a guide rail, a slider, and two push plates. The slider slides horizontally on the guide rail, and the two push plates are vertically symmetrically arranged on both sides of the slider. The two push plates are respectively used to push the two vertical sides of the U-bolt.

[0056] Specifically, during the production process, when the initial forming of the U-bolt is completed, the pusher starts working. The slider slides on the guide rail, driving the push plates on both sides to move toward the two vertical sides of the U-bolt at the same time. The push plates gently push the vertical sides of the U-bolt to make it straighter and meet the process requirements. After the pushing is completed, the pusher will reset and prepare for the adjustment of the next U-bolt.

[0057] The second aspect of this application is as follows Figures 3 to 10 As shown, a U-bolt production and forming device is provided, comprising the above-mentioned forming mechanism 100; and further comprising:

[0058] The material preparation mechanism 200 is used for straightening, cutting and thread rolling of the steel wire material;

[0060] In some embodiments, the material preparation mechanism includes: a frame 7, the frame 7 is provided with a workbench 8;

[0061] The straightening and feeding mechanism 9 is used to straighten the steel wire material and convey it backward; the cutting mechanism 10 includes a support plate 11, a shearing plate 12 and a guide cylinder 13, the guide cylinder 13 is fixed to the frame 7, the shearing plate 12 moves through the guide cylinder 13, and is arranged in close contact with the support plate 11, the support plate 11 is provided with a guide hole, the guide hole is used to guide the steel wire material to the horizontal suspension above the workbench 8, the shearing plate 12 and the support plate 11 perform a shearing action to cut the steel wire material into a predetermined length; the pushing mechanism 14 includes a horizontal guide plate 15 and a movable push plate 16, the horizontal guide plate 15 is fixed to the frame 7, and the movable push plate 16 is provided with a guide hole. 16 slides left and right on the horizontal guide plate 15 and fits with the workbench 8; the movable push plate 16 pushes the cut steel wire material along the workbench 8 to the thread rolling mechanism 17; the thread rolling mechanism 17 includes a fixed thread plate 18 and a movable thread plate 19, the fixed thread plate 18 is vertically fixed to the left hanging wall of the workbench 8, the movable thread plate 19 is arranged parallel to the fixed thread plate 18 and is driven by the second transmission mechanism to move up and down relative to the fixed thread plate 18 to complete the thread rolling operation; the second driving device and the second transmission mechanism, wherein the second transmission mechanism is used to transmit the power of the second driving device to each material preparation actuator.

[0062] Specifically, after the equipment is started, the straightening and feeding mechanism 9 straightens the steel wire from the front end and conveys it backward along the direction set by the equipment; the steel wire is guided by the guide hole on the support plate 11 so that it is in a horizontal suspension state, and the shear plate 12 performs a shearing action with the support plate 11 under power drive to cut the steel wire according to a predetermined length; the cut steel wire falls on the workbench, and the movable push plate 16 slides on the horizontal guide plate 15 to push the steel wire from the workbench to the thread rolling mechanism; the steel wire is pushed between the fixed tooth plate 18 and the movable tooth plate 19, and the movable tooth plate 19 moves up and down relative to the fixed tooth plate 18 under the drive of the second transmission mechanism to complete the thread rolling operation, so that the required threads are formed at both ends of the steel wire, and the preparation for the manufacture of U-bolts is completed.

[0063] The second driving device provides power, and the second transmission mechanism transmits the power to the straightening and feeding mechanism 9, the cutting mechanism 10, the pushing mechanism 14 and the thread rolling mechanism 17, and coordinates them to work in sequence and in an orderly manner according to the process requirements. The second transmission mechanism includes multiple transmission shafts, gear sets, connecting rods, and cams, and those skilled in the art can easily combine and apply them according to the process requirements to achieve corresponding functional actions.

[0064] The equipment of this embodiment realizes fully automated operation from feeding, cutting, pushing to thread rolling, improves production efficiency, is simple and convenient to operate, reduces manual intervention, and reduces labor intensity; through precise cutting mechanism and transmission mechanism, the accuracy of the cut length of the steel wire and the thread rolling position is ensured.

[0065] In some embodiments, the movable push plate 16 pushes the steel wire material to contact the movable tooth plate 19. The movable tooth plate 19 moves downward under the drive of the second transmission mechanism, and cooperates with the fixed tooth plate 18 to rub the steel wire material until the steel wire material moves to the lower end of the fixed tooth plate 18 and falls, completing the material preparation.

[0066] Specifically, as the movable tooth plate 19 continues to move downward, the steel wire material gradually moves to the lower end of the fixed tooth plate 18 during the tooth rolling process. When the steel wire material completes the tooth rolling, due to the effect of gravity, the steel wire material falls from the lower end of the fixed tooth plate 18, indicating the completion of the material preparation process; through the precise cooperation of the movable push plate 16 and the movable tooth plate 19, the position accuracy of the steel wire material during the tooth rolling process can be ensured, thereby improving the processing accuracy of the product.

[0069] The conveying component 20 realizes continuous conveying, and the dividing component 21 and the pushing component 22 cooperate to convert the continuously conveyed steel wire materials into ones that are pushed to the forming station one by one, that is, the first straight line groove and the second straight line groove, so as to facilitate the setting of the pushing interval in accordance with the rhythm of the forming process; the narrow mouth 26 design of the receiving groove 23 ensures that only a single steel wire material passes through each time, and the dividing device 27 and the positioning groove 25 further ensure the accurate positioning of the steel wire material before processing, thereby improving the processing accuracy.

[0070] In some embodiments, the push assembly 22 includes a second guide rail 28, a slider 29, a push rod 30, and a push drive device. The push rod 30 is movably disposed in the positioning groove 25 and is coaxially aligned with the steel wire in the positioning groove 25. The push rod 30 is connected to the slider 29. The slider 29 slides along the second guide rail 28 under the drive of the push drive device to drive the push rod 30 to axially push the steel wire to the forming station. The automated pushing operation of the push assembly 22 enables the steel wire to be pushed to the forming station continuously and quickly, thereby improving production efficiency.

[0071] Optionally, instead of using a separate push drive device, a first transmission device is used to distribute the power of the first drive device to the slider 29 so that the slider 29 slides along the second guide rail 28 .

[0072] That is to say, only one power source is used, and the first transmission device is used to distribute the power to the press 3, the pusher 4 and the slider 29 respectively, so that the three can move in the order of the process flow. Specifically, the press first bends the steel wire into shape, and the pusher pushes out the formed U-bolt. At the same time, the slider 29 pushes the push rod 30 to axially move the steel wire to the forming station, that is, the first linear groove and the second linear groove. In this way, the movement process of the press 3, the pusher 4 and the slider 29 can be conveniently controlled by adjusting the position, structure and number of the accessories of the first transmission device. The adjustment is flexible and convenient, and the degree of automation is high.

[0073] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
