Description

Technical Field

[0001] This utility model relates to the technical field of cold heading machine accessories, specifically to a material blocking component for a cold heading machine used for processing fasteners. Background Technology

[0002] In modern fastener manufacturing, cold heading machines, as highly efficient forming equipment, are widely used in fastener production. Cold heading machines primarily use molds to cold-process metal to produce fasteners of various specifications. However, due to the characteristics of metal materials, precise control of material feeding and positioning is often required during cold heading to ensure product accuracy and production efficiency.

[0003] Most current cold heading machine baffle systems cannot achieve flexible and precise adjustment. Furthermore, when multiple stations are operating, all baffles need to move simultaneously. When only some stations are working, this setup results in a high load on the drive motor and increased energy consumption. Therefore, designing a baffle structure that can flexibly control the movement of the baffles in a multi-station cold heading machine has become a pressing problem in the industry. Utility Model Content

[0004] This utility model proposes a material blocking component for a cold heading machine used for processing fasteners, which solves the problems of the fact that most cold heading machine material blocking systems in related technologies cannot achieve flexible and precise adjustment, and that when multiple workstations are working, all baffles need to operate simultaneously. When only some workstations are working, this setting method will result in a large load on the drive motor and a corresponding increase in energy consumption.

[0005] The technical solution of this utility model is as follows:

[0006] A material stop assembly for a cold heading machine used for machining fasteners includes:

[0007] Mounting plate, there are two mounting plates, and a connecting shaft is fixed between the corners of the two mounting plates. Several sets of mounting shells are slidably mounted on the connecting shaft. A baffle is rotatably mounted on the front wall of each mounting shell. Adjacent mounting shells are connected by a connecting mechanism. The leftmost mounting shell is fixedly connected to the left mounting plate.

[0008] A rotating mechanism is installed inside the mounting housing and is used to control the deflection of the baffle.

[0009] A drive motor is fixed to the outer wall of the left mounting plate, and the drive motor is used to drive the rotating mechanism.

[0010] Preferably, the outer wall of the mounting shell is symmetrically fixed with sliders, and the sliders are slidably mounted on the corresponding connecting shafts.

[0011] Preferably, the rotating mechanism includes a worm gear, a mounting shaft is fixed at the center of the worm gear, and a worm is meshed with the worm gear;

[0012] The mounting shaft is rotatably mounted between the inner walls of the mounting housing, and one end of the mounting shaft passes through the front wall of the mounting housing via a bearing and is fixedly connected to the top of the baffle.

[0013] The worm gear is rotatably mounted on the top wall of the inner cavity of the mounting housing via a mounting base. One end of the worm gear has a limit hole, and the other end of the worm gear is fixed with a locking block that cooperates with the limit hole.

[0014] Preferably, the worm gear has an arc-shaped through groove, and a limit rod is fixed to the rear wall of the inner cavity of the mounting housing. The limit rod is slidably connected to the inner wall of the arc-shaped through groove.

[0015] Preferably, the output end of the drive motor passes through the left mounting plate via a bearing and is fixedly connected to the leftmost end of the worm gear.

[0016] Preferably, the connecting mechanism includes a connecting plate, one end of which is rotatably mounted on one side of the top wall of the mounting shell, and the other end of which has a mounting hole;

[0017] A bolt is installed in the mounting hole, and a threaded hole that mates with the bolt is opened on the other side of the top wall of the mounting shell.

[0018] Preferably, each of the outer bottom sides of the mounting plate is fixed with a mounting block, and the mounting block has through holes for mating screws.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. The material blocking component in this utility model achieves efficient material blocking and unblocking operations through the cooperation of the rotating mechanism and the drive motor. Especially in multi-station cold heading machines, it can drive the baffle to rotate only at the working station, avoiding the movement of baffles at other non-working stations, thereby reducing the overall load of the system and reducing unnecessary energy consumption.

[0022] 2.

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0031] Example 1

[0032] like Figures 1-4 As shown, this embodiment proposes:

[0033] A material stop assembly for a cold heading machine used for machining fasteners includes:

[0034] Mounting plate 1, there are two mounting plates 1, and a connecting shaft 2 is fixed between the corners of the two mounting plates 1. Several sets of mounting shells 3 are slidably mounted on the connecting shaft 2. A baffle 4 is rotatably mounted on the front wall of each mounting shell 3. Adjacent mounting shells 3 are connected by a connecting mechanism 7. The leftmost mounting shell 3 is fixedly connected to the left mounting plate 1.

[0035] Rotating mechanism 5 is installed inside the mounting housing 3 and is used to control the deflection of baffle 4.

[0036] The drive motor 6 is fixed on the outer wall of the left mounting plate 1 and is used to drive the rotating mechanism 5.

[0037] Slider 9s are symmetrically fixed on the outer wall of the mounting shell 3, and slider 9s are slidably mounted on the corresponding connecting shaft 2.

[0038] Mounting blocks 8 are fixed to the bottom outer side of mounting plate 1, and through holes for mating screws are provided on mounting blocks 8.

[0039] The drive motor 6 is either a stepper motor or a servo motor.

[0040] In this embodiment, the mounting plate 1 and the connecting shaft 2 form an external frame. The mounting block 8 and screws are used to install the device on a multi-station cold heading machine. The mounting shell 3 is used to install the baffle 4 and the rotating mechanism 5. The rotating mechanism 5 is used to adjust the rotation angle of the baffle 4, which can realize the operation of blocking and releasing materials. Adjacent mounting shells 3 are connected by the connecting mechanism 7. When only some stations of the multi-station cold heading machine are working, the baffle 4 that is not working at the rear can be moved to the right side of the frame, so that the drive motor 6 only drives the baffle 4 at the current working station to rotate, thereby reducing the load on the drive motor 6 and avoiding unnecessary energy consumption.

[0041] Example 2

[0042] like Figures 3-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes:

[0043] The rotating mechanism 5 includes a worm gear 51, a mounting shaft 52 fixed at the center of the worm gear 51, and a worm 53 meshing with the worm gear 51;

[0044] The mounting shaft 52 is rotatably mounted between the inner walls of the mounting housing 3. One end of the mounting shaft 52 passes through the front wall of the mounting housing 3 via a bearing and is fixedly connected to the top of the baffle 4.

[0045] The worm gear 53 is rotatably mounted on the top wall of the inner cavity of the mounting shell 3 via the mounting base 54. One end of the worm gear 53 has a limit hole 55, and the other end of the worm gear 53 is fixed with a locking block 56 that cooperates with the limit hole 55.

[0046] The worm gear 51 has an arc-shaped through groove 57, and a limit rod 58 is fixed to the rear wall of the inner cavity of the mounting shell 3. The limit rod 58 is slidably connected to the inner wall of the arc-shaped through groove 57.

[0047] The output end of the drive motor 6 passes through the left mounting plate 1 via a bearing and is fixedly connected to one end of the leftmost worm gear 53.

[0048] The connecting mechanism 7 includes a connecting plate 71, one end of which is rotatably mounted on one side of the top wall of the mounting shell 3, and the other end of which is provided with a mounting hole 72;

[0049] A bolt 73 is installed in the mounting hole 72, and a threaded hole 74 that mates with the bolt 73 is opened on the other side of the top wall of the mounting shell 3.

[0050] In this embodiment, the rotating mechanism 5 is used in conjunction with the drive motor 6 to rotate the baffle 4, realizing the material blocking and unloading operations of the cold heading machine. The connecting mechanism 7 controls the connection between adjacent mounting shells 3. When it is necessary to rotate the baffle 4, the starter motor 6 is turned on, and the drive motor 6 drives the corresponding worm 53 to rotate. The worm 53 drives the baffle 4 to deflect through the worm wheel 51 and the mounting shaft 52. At the same time, limit holes 55 and locking blocks 56 are respectively provided at both ends of the worm 53, so that the two worms 53 can rotate synchronously after the two mounting shells 3 are installed. The limit rod 58, in conjunction with the arc-shaped through groove 57, makes the worm wheel 51 unable to rotate after rotating to a certain angle. The connection and separation of adjacent worms 53 are based on this state, thus ensuring that the deflection angle of the baffle is always the same after the worms 53 are connected. When the mounting shells 3 are abutting together, the connecting plate 71 is rotated so that the mounting hole 72 on the connecting plate 71 corresponds to the threaded hole 74 on the adjacent mounting shell 3, and they are connected by the provided screw 73.

[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
