DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. 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.

[0029] 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.

[0030] 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 components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figures 1 to 5 As shown, a material unloading and unloading mechanism for bolt production equipment includes a material unloading mechanism, a material unloading mechanism, a driving device and a transmission assembly; the material unloading mechanism is used to place the bolt blank on the clamping station, and the material unloading mechanism is used to unload the processed bolt blank; the material unloading mechanism includes: a fixed plate 1, which is vertically fixed to the main frame of the hot heading machine; a slider 2, which is slidably arranged on the fixed plate 1; a clamping jaw assembly, including a clamping rod 3 connected to the slider 2 and an elastic clip 4 affixed to the side wall of the clamping rod 3, the lower end of the side wall of the clamping rod 3 affixed to the elastic clip 4 is provided with a limiting groove 301, the lower end of the elastic clip 4 can be elastically tilted relative to the clamping rod 3, and the lower end of the clamping rod 3 and / or the elastic clip 4 is provided with a groove for feeding; the driving device provides power, and the transmission assembly transmits the power to the material unloading and unloading mechanism and the material unloading mechanism respectively to realize the material unloading and unloading action.

[0032] Among them, the clamping mechanism is used to clamp the bolts of the hot forging machine feeding mechanism, and then place them in the positioning mold to facilitate the bolt heading process. Specifically, the feeding mechanism is provided with a push plate. When the push plate carrying the bolt moves to the bottom of the clamping jaw assembly, the transmission assembly drives the slider 2 to descend. During this process, the clamp rod 3 contacts the bolt, and the bolt squeezes the elastic clip 4, causing it to elastically deform outward, so that the bolt can smoothly enter the limit groove 301. As the clamping jaw assembly continues to descend until the clamp rod 3 is supported by the push plate, the bolt is completely accommodated in the limit groove 301, and the bolt is clamped; then, the push plate retreats to the initial position, the clamping jaw assembly continues to descend to the positioning mold with the bolt, the positioning mold clamps the bolt, the transmission assembly drives the slider 2 to rise, the bolt comes out of the limit groove 301, squeezes the elastic clip 4 out of the clamping jaw assembly, and the elastic clip 4 returns to its original state under the action of its own elasticity, completing the discharge action.

[0033] In this embodiment, the automatic clamping and automatic placement of the bolts are achieved only by controlling the lifting and lowering of the slider 2 and the clamping jaw assembly. The control logic is simple and has high reliability and stability, which not only simplifies the operation process but also improves production efficiency and automation level.

[0034] The clamping jaw assembly includes a clamping rod 3 and an elastic clamping piece 4. The clamping rod 3 is provided with a limiting groove 301. This design does not require an additional driving device to drive the clamping jaw to clamp and release, making the structure simpler, the operation more convenient, reducing energy consumption and maintenance costs, and having high practicality and economy.

[0035] By integrating the unloading and unloading mechanisms and using the same transmission mechanism to drive the unloading and unloading mechanisms, the driving part of the entire system can be significantly simplified, which not only reduces the number of required driving devices, but also reduces the complexity and maintenance costs of the system, helps to optimize the spatial layout of the equipment, reduce the floor space, make the production line more compact, and improve space utilization efficiency.

[0036] Since the unloading mechanism and the unloading mechanism are driven by the same transmission mechanism, their actions can be coordinated and synchronized more accurately. This coordination ensures the smooth progress of the production process, reduces unnecessary waiting time, thereby improving overall production efficiency and avoiding conflicts or delays.

[0037] In some embodiments, a baffle 5 is provided at the upper end of the fixed plate 1, a compression spring is provided between the baffle 5 and the slider 2, a guide rod 6 passing through the compression spring and the baffle 5 is connected to the upper end of the slider 2, and a limit cap 7 is provided at the upper end of the guide rod 6. By providing a compression spring, a downward force is always exerted on the slider 2, so the transmission component only needs to accurately control the upward displacement of the slider 2, which further simplifies the control logic and improves the stability and reliability of the system.

[0038] In some embodiments, the transmission assembly includes: a first rotating shaft 8, which is rotatably connected to the main frame and is used to connect to the driving device to transmit power; a first cam 9, which is connected to the first rotating shaft 8 and rotates synchronously; a first connecting rod 10, one end of which is rotatably connected to the main frame through a first hinge seat, and the other end is rotatably connected to the second connecting rod 11, and the first cam 9 abuts against the upper side of the rod body of the first connecting rod 10; a third connecting rod 12, one end of which is hingedly connected to the second connecting rod 11, and the other end is rotatably connected to the slider 2, and the rod body of the third connecting rod 12 is rotatably connected to the main frame through a second hinge seat.

[0039] Specifically, the first rotating shaft 8 drives the first cam 9 to rotate. Since the first cam 9 is in contact with the first connecting rod 10, the first cam can drive the first connecting rod 10 to swing up and down. The first connecting rod 10 drives the second connecting rod 11 to move up and down. The second connecting rod 11 drives the third connecting rod 12 to rotate at the fulcrum. The third connecting rod 12 drives the slider 2 to rise and fall.

[0040] When the convex part of the first cam 9 contacts the first connecting rod 10, the slider 2 is at a high position; when the flat part of the first cam 9 contacts the first connecting rod 10, the slider 2 is at a high position; when the clamping jaw assembly descends until the clamping rod 3 is supported by the push plate, the first cam 9 and the first connecting rod 10 are in a disengaged state. By limiting the end, the design of the first cam is simplified, and there is no need to consider the contour design during the entire rotation cycle, nor the wear of the first cam.

[0041] In some embodiments, two clamping jaw assemblies are provided on one side of the slider 2, which are used to clamp the two ends of the bolt respectively, and the spacing between the two clamping jaw assemblies on the slider 2 is adjustable. For example, the clamping jaw assembly can be installed in the slide groove of the slider 2, and the spacing between the two clamping jaw assemblies can be adjusted through the sliding and locking mechanism. By clamping both ends of the bolt at the same time, it can ensure that the bolt is more stable during the clamping and transportation process, reducing the risk of falling off or offset. The clamping jaw assembly with adjustable spacing allows the clamping mechanism to adapt to bolts of different lengths, thereby improving the versatility and flexibility of the device.

[0042] In some embodiments, the upper end of the clamping rod 3 is rotatably connected to the slider 2 via a third hinge seat, so that the clamping rod 3 can swing. The swingable design of the clamping rod 3 enables the clamping jaw assembly to more flexibly adapt to bolts of different sizes and shapes, and appropriately adjust its own position, thereby improving the accuracy and success rate of clamping.

[0043] In some embodiments, the third hinge seat is connected to an insertion rod 13, and the clamping rod 3 is provided with a through slot, and the insertion rod 13 passes through the slot, and there is a gap between the insertion rod 13 and the slot to limit the swing angle of the clamping rod. When the clamping rod 3 swings to the extreme position, the insertion rod 13 will contact the edge of the slot, preventing the clamping rod 3 from continuing to swing, thereby achieving precise control of the swing angle of the clamping rod. Limiting the swing angle of the clamping rod 3 can avoid problems such as instability of the clamping jaw assembly or bolt falling off due to excessive swinging, thereby improving the stability and reliability of the clamping process.

[0044] In some embodiments, Figure 5 As shown, the material stripping mechanism includes: a material stripping plate 14, which is arranged on one side of the clamping module and can move horizontally and radially relative to the bolt blank; a movable push rod 15, one end of which is connected to the material stripping plate 14, and the other end is connected to the swing assembly; a reset spring 16 is provided on the movable push rod 15, one end of the reset spring 16 is connected to the end baffle of the movable push rod 15, and the other end is connected to the main frame; a second cam 17 is connected to the first rotating shaft 8 and rotates synchronously, and the second cam 17 drives the swing assembly to swing back and forth.

[0045] When it is necessary to withdraw the material, the second cam 17 starts to rotate, driving the swing assembly to swing back and forth. The movement of the swing assembly is transmitted to the stripping plate 14 through the movable push rod 15, causing it to move horizontally and radially. The movement of the stripping plate 14 pushes the bolt blank to realize the stripping action. When the stripping action is completed, the reset spring 16 helps the movable push rod 15 and the stripping plate 14 to reset and prepare for the next material stripping.

[0046] In some embodiments, Figure 5 As shown, the swing assembly includes a fourth connecting rod 18, a second rotating shaft 19 and a swing plate 20, the second rotating shaft 19 is rotatably connected to the main frame, one end of the second rotating shaft 19 is fixedly connected to the fourth connecting rod 18, and the other end is fixedly connected to the swing plate 20; the fourth connecting rod 18 abuts against the second cam 17, and the swing plate 20 abuts against the movable push rod 15.

[0047] When the second cam 17 rotates, its contour shape causes the fourth connecting rod 18 to produce a corresponding swinging motion. The fourth connecting rod 18 drives the swinging plate 20 to swing through the second rotating shaft 19. The swinging of the swinging plate 20 pushes the movable push rod 15 to move linearly, thereby driving the stripping plate 14 to perform the stripping action.

[0048] Although the 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.
