Description

Technical Field

[0001] This utility model relates to the field of thread rolling machine technology, specifically to a bolt thread rolling machine. Background Technology

[0002] Thread rolling machine is a multi-functional cold extrusion forming machine tool. It can perform thread rolling, straight knitting, and oblique knitting on workpieces in a cold state within its rolling pressure range. The thread rolling machine has a pair of rolling wheels with the same parameters, which are respectively installed on the two main shafts of the thread rolling machine, and can roll threads on the surface of the workpiece.

[0003] Existing thread rolling machines often use a single vibratory feeder for feeding, which can easily lead to bolt blockage and uneven bolt arrangement, causing feeding interruptions and affecting production continuity. Other feeding mechanisms are complex in structure, have high maintenance costs, and lack precise control over feeding speed and accuracy, thus limiting the overall production quality and efficiency of bolt thread rolling. Therefore, there is an urgent need to improve the feeding mechanism of bolt thread rolling machines to increase production efficiency and ensure feeding stability and accuracy. Utility Model Content

[0004] This utility model proposes a bolt thread rolling machine, which solves the problems of bolt clogging and uneven material discharge during feeding in some related thread rolling machines, as well as the complex structure and high maintenance cost of some feeding mechanisms.

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

[0006] A bolt thread rolling machine, comprising:

[0007] The device body has a thread rolling mechanism at one end of its upper part and a feeding mechanism at the other end of its upper part.

[0008] The feeding mechanism includes a feeding box, which is fixedly installed on the front side of the main body of the device;

[0009] The top of the feeding box is fixedly connected to a feeding hopper, and the inside of the feeding hopper is movably connected to a grading feeding plate.

[0010] Preferably, a second electric push rod is fixedly connected to the bottom end of the grading feeding plate, the second electric push rod is fixedly installed inside the feeding box, a stopping platform is fixedly connected to a part of the grading feeding plate installed inside the feeding hopper, and the internal slope of the feeding hopper gradually decreases from right to left.

[0011] Preferably, a feeding guide rail is fixedly connected to the left end of the feeding hopper, and a third electric push rod is fixedly connected to the upper end of the feeding hopper away from the feeding guide rail.

[0012] Preferably, the output end of the third electric push rod is fixedly connected to a pusher block, which is disposed inside the feeding guide rail, and the outer diameter of the pusher block matches the inner diameter of the feeding guide rail.

[0013] Preferably, a slide is provided on the top surface of the main body of the device, and a feeding plate is fixedly connected to the middle of the top of the main body of the device.

[0014] Preferably, the thread rolling mechanism includes a movable seat, a first motor, and a fixed seat. The first motor is fixedly installed at the right end of the main body of the device, and a lead screw is fixedly connected to the output shaft of the first motor. The lead screw is rotatably installed inside the main body of the device.

[0015] Preferably, the lead screw passes through the bottom end of the movable seat and is threadedly connected to the movable seat. The movable seat is movably connected to the main body of the device. A mounting bracket is fixedly connected to one end of the movable seat. A first electric push rod is fixedly connected to the end of the mounting bracket away from the movable seat. A limit block is fixedly connected to the output end of the first electric push rod. A first rolling wheel is rotatably connected to another part of the movable seat. A second motor is fixedly connected to the end of the movable seat where the first rolling wheel is mounted. The output shaft of the second motor is fixedly connected to the first rolling wheel.

[0016] Preferably, the fixing base is fixedly installed on the top left side of the main body of the device, the right end of the fixing base is rotatably connected to a second rolling wheel, and the other end of the right end of the fixing base is fixedly connected to a third motor, the output shaft of the third motor being fixedly connected to the second rolling wheel.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] 1. In this utility model, the second electric push rod drives the lifting and lowering of the graded feeding plate to complete the stepped feeding of bolts. In conjunction with the third electric push rod, the pusher block moves forward in the track of the feeding guide rail, pushing the bolts between the two sets of rolling rollers for thread rolling. Through the stepped feeding structure and the precise pushing of the third electric push rod, the bolts are accurately placed between the two sets of rolling rollers, and the bolt jamming phenomenon is avoided during the feeding process, which greatly improves the feeding speed.

[0019] 2. In this utility model, two sets of opposing rolling rollers are used to perform thread rolling on bolts. A first motor drives a lead screw to rotate, which in turn moves a movable seat. By adjusting the distance between the first and second rolling rollers, the bolts are easily unloaded after thread rolling and loaded before thread rolling. The device can also perform thread rolling on bolts of different diameters. A first electric push rod drives a limiting block to move between the two sets of rolling rollers, limiting the bolt's top plate and thus limiting the thread rolling length. This allows the device to control the thread rolling length of the bolts, increasing its applicability. Attached Figure Description

[0026] 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.

[0027] Example 1

[0028] like Figures 1-3 As shown, this embodiment proposes...

[0029] A bolt thread rolling machine includes: a main body 1, a thread rolling mechanism 2 is provided at one end of the upper part of the main body 1, and a feeding mechanism 3 is provided at another end of the upper part of the main body 1; the feeding mechanism 3 includes a feeding box 31, which is fixedly installed on the front side of the main body 1; a feeding hopper 32 is fixedly connected to the top of the feeding box 31, and a graded feeding plate 33 is movably connected inside the feeding hopper 32.

[0030] The bottom end of the grading feeding plate 33 is fixedly connected to a second electric push rod 34, which is fixedly installed inside the feeding box 31. The feeding hopper 32 is installed inside the grading feeding plate 33 and a stopping platform 35 is fixedly connected to one of its parts. The internal slope of the feeding hopper 32 gradually decreases from right to left.

[0031] The left end of the feeding hopper 32 is fixedly connected to the feeding guide rail 36, and the upper end of the feeding hopper 32 away from the feeding guide rail 36 is fixedly connected to the third electric push rod 37.

[0032] The output end of the third electric push rod 37 is fixedly connected to a pusher block 38, which is located inside the feeding guide rail 36. The outer diameter of the pusher block 38 matches the inner diameter of the feeding guide rail 36.

[0033] In this embodiment, after the user places the bolts inside the feeding hopper 32 and arranges them in sequence, the second electric push rod 34 drives the grading feeding plate 33 to reciprocate up and down. When the grading feeding plate 33 descends, the bolts roll into the top of the push plate of the grading feeding plate 33. When the grading feeding plate 33 rises, it pushes the bolt into the next level stop plate 35. When the grading feeding plate 33 descends again, the bolts on the next level stop plate 35 roll into the next level push plate of the grading feeding plate 33. This action is repeated until the bolts finally enter the feeding guide rail 36. After the bolts enter the feeding guide rail 36, the third electric push rod 37 pushes the push block 38 to move forward in the track of the feeding guide rail 36. The push block 38 pushes the bolts between the two sets of rolling rollers for thread rolling, completing the bolt feeding work. The stepped feeding structure combined with the precise push of the third electric push rod 37 greatly improves the feeding speed.

[0034] Example 2

[0035] like Figures 3-4 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes:

[0036] A slide 11 is provided on the top surface of the main body 1 of the device, and a feeding plate 12 is fixedly connected to the middle of the top of the main body 1 of the device.

[0037] The thread rolling mechanism 2 includes a movable seat 21, a first motor 22 and a fixed seat 29. The first motor 22 is fixedly installed at the right end of the main body 1 of the device. The output shaft of the first motor 22 is fixedly connected to a lead screw 23, which is rotatably installed inside the main body 1 of the device.

[0038] The lead screw 23 passes through the bottom end of the movable seat 21 and is threadedly connected to the movable seat 21. The movable seat 21 is movably connected to the main body 1 of the device. One end of the movable seat 21 is fixedly connected to the mounting bracket 24. The end of the mounting bracket 24 away from the movable seat 21 is fixedly connected to the first electric push rod 25. The output end of the first electric push rod 25 is fixedly connected to the limit block 26. The other part of the movable seat 21 is rotatably connected to the first rolling wheel 27. The end of the movable seat 21 on which the first rolling wheel 27 is mounted is fixedly connected to the second motor 28. The output shaft of the second motor 28 is fixedly connected to the first rolling wheel 27.

[0039] The fixed base 29 is fixedly installed on the top left side of the main body 1 of the device. The right end of the fixed base 29 is rotatably connected to the second rolling wheel 210. The other end of the right end of the fixed base 29 is fixedly connected to the third motor 211. The output shaft of the third motor 211 is fixedly connected to the second rolling wheel 210.

[0040] In this embodiment, the second rolling wheel 210 is driven to rotate by the third motor 211, the first rolling wheel 27 is driven to rotate by the second motor 28, and the lead screw 23 is driven to rotate by the first motor 22. This causes the moving seat 21 to move left and right within the range of the main body 1 of the device. When the bolt enters between the two sets of rolling wheels, the moving seat 21 moves forward to roll the bolt. The limiting block 26 is driven by the first electric push rod 25 to move between the two sets of rolling wheels, limiting the top of the bolt, thereby restricting the length of the bolt's rolling. The setting of the first electric push rod 25 can adjust the limiting distance of the limiting block 26, thereby changing the thread rolling length of the bolt. After the bolt is threaded, the moving seat 21 moves backward, and the pusher block 38 pushes the bolt in the feeding guide rail 36 forward, so that the threaded bolt falls into the unloading plate 12. The next bolt is pushed between the two sets of rolling rollers, and the moving seat 21 moves forward again to perform thread rolling on the bolt, completing the continuous thread rolling process of the bolt. The user can place a collection box at the discharge port of the unloading plate 12 to collect the threaded bolt.

[0041] 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.
