Description

Technical Field

[0001] This utility model relates to the field of cold heading machine technology, and in particular to a feeding device for a cold heading machine with adjustable feeding length. Background Technology

[0002] Cold heading machines are specialized equipment used for the mass production of fasteners such as nuts and bolts, primarily based on the heading process. They typically take a cylindrical blank and shape it into a nut or other part through the action of opening and closing the mold.

[0003] Existing cold heading machines use pulleys and ratchet mechanisms for feeding. Different pulley structures are required when feeding raw materials of different sizes to different lengths, and changing the pulley structure will affect production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding device for a cold heading machine with adjustable feeding length, so as to solve the problem mentioned in the background art that the existing cold heading machine uses a pulley and ratchet structure for feeding during the feeding process. When feeding raw materials of different sizes to different lengths, different pulley structures are required, and changing the pulley structure will affect the production efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a feeding device for a cold heading machine with adjustable feeding length, comprising:

[0007] Support assembly, the support assembly including a base plate;

[0008] The feeding assembly includes a slide rail, a support frame, a hydraulic cylinder, a movable plate, a guide groove, a connecting rod, a support plate, and a pneumatic clamp. The slide rail is fixedly connected to one side of the upper end of the base plate, the support frame is fixedly connected to one side of the upper end of the slide rail, the hydraulic cylinder is fixedly connected to the top of the support frame, the movable plate is fixedly connected to the bottom of the hydraulic cylinder, the guide groove is opened on the inner side of the support frame, the connecting rod is rotatably connected to the bottom of the movable plate, the support plate is rotatably connected to the lower end of the connecting rod, and the pneumatic clamp is fixedly connected to the bottom of the support plate.

[0009] Furthermore, the support assembly also includes a straightening wheel, which is rotatably connected to the other side of the upper end of the base plate.

[0010] Furthermore, the lower end of the hydraulic cylinder extends upward through the support frame, and the movable plate is slidably connected to the inside of the guide groove.

[0011] Furthermore, the support plate is slidably connected to the upper end of the slide rail, and the connecting rod is in an inclined state.

[0012] Furthermore, it also includes a positioning component, which includes a baffle, a slider, a fixing screw, a pressure sensor, a telescopic spring, and a top plate. The baffle is placed at the upper end of the slide rail, the slider is fixedly connected to both sides of the bottom end of the baffle, the fixing screw is threadedly connected to both sides of the baffle, the pressure sensor is fixedly connected to the inside of the baffle, the telescopic spring is fixedly connected to the outer end of the pressure sensor, and the top plate is fixedly connected to the outer end of the telescopic spring.

[0013] Furthermore, the slider is slidably connected to the upper end of the slide rail, and the pressure sensor is electrically connected to the hydraulic cylinder via a circuit.

[0014] This application uses a feeding assembly. A hydraulic cylinder drives a movable plate to move downwards, which in turn drives a connecting rod to rotate. The connecting rod then drives a support plate to slide along a slide rail, causing the support plate to move a pneumatic clamp. The feeding length can be adjusted by changing the stroke of the hydraulic cylinder. The pneumatic clamp can feed raw materials of different sizes. The operation is simple and convenient.

[0015] This application uses a positioning component to move the baffle on the slide rail, causing the baffle to block the support plate. When the support plate moves towards the baffle, it drives the top plate to move inward. The movement of the top plate compresses the telescopic spring. A pressure sensor measures the spring force. When the top plate moves and compresses the telescopic spring to a set value, the pressure sensor controls the hydraulic cylinder to stop. This allows the movement of the movable plate and the support plate to be positioned, preventing excessive movement of the hydraulic cylinder and excessive feeding. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] Please see Figure 1-3 As shown, this embodiment is a feeding device for a cold heading machine with adjustable feed length, comprising:

[0024] Support components, including base plate 11;

[0025] The feeding assembly includes a slide rail 21, a support frame 22, a hydraulic cylinder 23, a movable plate 24, a guide groove 25, a connecting rod 26, a support plate 27, and a pneumatic clamp 28. The slide rail 21 is fixedly connected to one side of the upper end of the base plate 11, the support frame 22 is fixedly connected to one side of the upper end of the slide rail 21, the hydraulic cylinder 23 is fixedly connected to the top of the support frame 22, the movable plate 24 is fixedly connected to the bottom of the hydraulic cylinder 23, the guide groove 25 is opened inside the support frame 22, the connecting rod 26 is rotatably connected to the bottom of the movable plate 24, the support plate 27 is rotatably connected to the lower end of the connecting rod 26, and the pneumatic clamp 28 is fixedly connected to the bottom of the support plate 27.

[0026] The slide rail 21 is used to support the support frame 22 and guide the support plate 27. The support frame 22 is used to support the hydraulic cylinder 23. The hydraulic cylinder 23 is used to drive the movable plate 24 to slide inside the guide groove 25. The guide groove 25 is used to guide the movement of the movable plate 24. The connecting rod 26 is used to rotate under the drive of the movable plate 24 and drive the support plate 27 to move. The support plate 27 is used to support the pneumatic clamp 28. The pneumatic clamp 28 is used to clamp the raw material.

[0027] The support assembly also includes a straightening wheel 12, which is rotatably connected to the other side of the upper end of the base plate 11;

[0028] The straightening wheel 12 is used to straighten the raw materials.

[0029] The lower end of the hydraulic cylinder 23 extends upward through the support frame 22, and the movable plate 24 is slidably connected to the inside of the guide groove 25;

[0030] When the hydraulic cylinder 23 extends downward, it can drive the movable plate 24 to move downward along the inside of the guide groove 25.

[0031] The support plate 27 is slidably connected to the upper end of the slide rail 21, and the connecting rod 26 is in an inclined state;

[0032] The upward movement of the movable plate 24 causes the connecting rod 26 to rotate, which in turn causes the supporting plate 27 to move horizontally.

[0033] When feeding material into the cold heading machine, the material is fed through the straightening wheel 12 and the pneumatic clamp 28 and into the cold heading machine. At this time, the pneumatic clamp 28 is controlled to clamp the material, and the hydraulic cylinder 23 is activated to extend downward. The extension of the hydraulic cylinder 23 drives the movable plate 24 to move downward along the guide groove 25. The downward movement of the movable plate 24 drives the connecting rod 26 to rotate. The rotation of the connecting rod 26 drives the support plate 27 to move horizontally along the upper end of the slide rail 21. The movement of the support plate 27 drives the pneumatic clamp 28 and the material to move forward, so that the material can be sent into the cold heading machine.

[0034] Please see Figure 4 As shown, this embodiment, based on the above embodiment, further includes:

[0035] The positioning assembly includes a baffle 31, a slider 32, a fixing screw 33, a pressure sensor 34, a telescopic spring 35, and a top plate 36. The baffle 31 is placed at the upper end of the slide rail 21. The slider 32 is fixedly connected to both sides of the bottom end of the baffle 31. The fixing screw 33 is threadedly connected to both sides of the baffle 31. The pressure sensor 34 is fixedly connected to the inside of the baffle 31. The telescopic spring 35 is fixedly connected to the outer end of the pressure sensor 34. The top plate 36 is fixedly connected to the outer end of the telescopic spring 35.

[0036] The baffle 31 is used to support the pressure sensor 34, the slider 32 is used to support and guide the baffle 31, the fixing screw 33 is used to limit the baffle 31, the pressure sensor 34 is used to measure the elastic force of the telescopic spring 35, the telescopic spring 35 is used to support the top plate 36, and the top plate 36 is used to drive the telescopic spring 35 to compress.

[0037] The slider 32 is slidably connected to the upper end of the slide rail 21, and the pressure sensor 34 is electrically connected to the hydraulic cylinder 23 through a circuit;

[0038] When the pressure sensor 34 measures that the elastic force of the extension spring 35 is at the set value, the pressure sensor 34 controls the hydraulic cylinder 23 to stop extending downward.

[0039] When the raw material is fed into the cold heading machine, the baffle 31 moves along the upper end of the slide rail 21 by moving the slider 32. When the baffle 31 moves to the desired position, the baffle 31 is fixed on the slide rail 21 by the fixing screw 33. At this time, when the support plate 27 moves the raw material by the pneumatic clamp 28, the support plate 27 moves outward and contacts the top plate 36, which in turn moves the top plate 36 into the baffle 31. The movement of the top plate 36 causes the telescopic spring 35 to be compressed. The pressure sensor 34 measures the elastic force of the telescopic spring 35. Since the elastic force of the telescopic spring 35 is proportional to its deformation, when the top plate 36 moves to the desired position, the deformation and elastic force of the telescopic spring 35 are corresponding values. When the elastic force of the telescopic spring 35 is at the set value, it means that the top plate 36 has moved a fixed distance under the action of the support plate 27. At this time, the pressure sensor 34 controls the hydraulic cylinder 23 to stop extending downward, which can prevent the feeding from being too long or too short.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
