Description

Technical Field

[0001] This application relates to the field of thread rolling machine technology, and in particular to a thread rolling machine for straightening metal rods. Background Technology

[0002] Thread rolling machine is a multi-functional cold extrusion forming machine tool that can perform threading, straightening, and other processing on workpieces in a cold state within its rolling pressure range.

[0003] Currently, existing thread rolling machines include a base, a worktable, two thread rolling wheels rotatably mounted on the worktable, a spindle and spindle box for mounting and driving the thread rolling wheels, and a radial feed mechanism. One thread rolling wheel's spindle box is fixed, while the other is movable. The radial feed mechanism drives the movable spindle box to move, thereby causing the corresponding thread rolling wheel to move radially and compress the metal rod. During processing, the operator holds one end of the metal rod directly by hand and inserts the other end between the two thread rolling rollers for positioning and feeding.

[0004] However, after the thread rolling machine is started, the thread rolling wheel will generate a certain amount of vibration when it applies rolling pressure to the metal rod. When the operator holds a long metal rod, it is difficult to maintain absolute stability, which can easily cause the feeding end of the metal rod to deflect and jump. In addition, when the metal rod being processed is short, the worker's hand is more likely to come into contact with the thread rolling wheel, which can lead to safety accidents. Utility Model Content

[0005] In order to improve the problems of unstable processing and poor operation safety of existing thread rolling machines that use manual hand-feeding, this application provides a thread rolling machine for straightening metal rods.

[0006] This application provides a thread rolling machine for straightening metal rods, which adopts the following technical solution:

[0007] A wire rolling machine for straightening metal rods includes a base, a worktable mounted on the base, two wire rolling wheels rotatably mounted on the worktable, a spindle and spindle box for driving the wire rolling wheels, and a radial feed mechanism. The worktable is provided with a feeding guide device on the feeding side of the wire rolling wheels. The feeding guide device includes a mounting base mounted on the worktable, a guide plate mounted on the mounting base, and a V-shaped guide groove formed on the top of the guide plate. The axis of the V-shaped guide groove is aligned with the extrusion center line between the two wire rolling wheels.

[0008] A positioning component for limiting the feeding depth of the metal rod is provided between the mounting base and the worktable.

[0009] Preferably, the positioning component includes a positioning block disposed at the bottom of the mounting base and a positioning screw rotatably disposed on the worktable. The positioning block is slidably disposed on the worktable, and the positioning block is threadedly connected to the positioning screw.

[0010] Preferably, the bottom end of the guide plate is provided with a connecting plate, and the mounting base is provided with a mounting plate for assembling the connecting plate. The connecting plate is detachably connected to the mounting plate by bolts and nuts.

[0011] Preferably, a vibration damping spring is provided between the connecting plate and the mounting plate. The vibration damping spring is located between the connecting plate and the mounting plate, and its two ends abut against the connecting plate and the mounting plate respectively. The vibration damping spring is sleeved on the bolt.

[0012] Preferably, the bottom of the connecting plate is provided with a rack that slides up and down and is connected to the mounting base, a gear that meshes with the rack is rotatably connected inside the mounting base, and a control motor that controls the rotation of the gear is provided outside the mounting base.

[0013] Preferably, the connecting plate is provided with a roller brush cylinder at the front end of the guide plate, and the inner arm of the roller brush cylinder is provided with an elastic brush strip.

[0014] In summary, the beneficial effects of this application are as follows:

[0015] 1. By setting up a feeding guide device and positioning components, this application allows the operator to simply place the metal rod to be processed in the V-shaped guide groove along the feeding direction during processing. The V-shaped groove supports and guides the metal rod, effectively suppressing the deflection and jumping of the metal rod's feed end caused by vibrations generated during the rolling process. This ensures that the axis of the metal rod is always aligned with the center line of the thread rolling wheel. In addition, the operator can stay away from the working area of ​​the thread rolling wheel, avoiding the risk of hand contact with the thread rolling wheel. This is especially suitable for processing short metal rods, greatly improving safety.

[0016] 2. The connecting plate in this application adopts a detachable connection method, which facilitates quick replacement of guide plates of different specifications, enabling the equipment to flexibly adapt to the processing of metal rods of different diameters and has strong versatility;

[0017] 3. The damping spring in this application can effectively absorb some of the vibration and prevent the vibration from being transmitted to the metal rod to be processed through the feeding guide device, thereby further improving the stability of the processing. Attached Figure Description

[0028] This application discloses a wire rolling machine for straightening metal rods, comprising a base 1, a worktable 2 disposed on the base 1, two wire rolling wheels 3 rotatably disposed on the worktable 2, a spindle and spindle box for driving the wire rolling wheels 3, and a radial feed mechanism. One of the spindle boxes of the wire rolling wheel 3 is fixed, while the other spindle box is movable. The radial feed mechanism drives the movable spindle box to move, thereby causing the corresponding wire rolling wheel 3 to move radially and compress the metal rod.

[0029] Furthermore, the worktable 2 is equipped with a feeding guide device 4 on the feeding side of the thread rolling wheels 3. The feeding guide device 4 includes a mounting base 41 on the worktable 2, a guide plate 42 above the mounting base 41, and a V-shaped guide groove 43 on the top of the guide plate 42. The axis of the V-shaped guide groove 43 is aligned with the extrusion center line between the two thread rolling wheels 3. During feeding, the V-shaped groove provides reliable radial support and guidance for the metal rod, effectively suppressing the deflection and jump of the metal rod's feeding end caused by vibration generated during the rolling process, ensuring that the axis of the metal rod is always aligned with the center line of the thread rolling wheels 3.

[0030] Furthermore, a connecting plate 421 is fixed to the bottom end of the guide plate 42, and the mounting base 41 is provided with a mounting plate 411 for assembling the connecting plate 421. The connecting plate 421 is detachably connected to the mounting plate 411 by four sets of bolts and nuts. In practical applications, guide plates 42 of different specifications can be quickly replaced, allowing the equipment to flexibly adapt to the processing of metal rods of different diameters and improving the versatility of the equipment.

[0031] Furthermore, a vibration damping spring 5 is provided between the connecting plate 421 and the mounting plate 411. The vibration damping spring 5 is located between the connecting plate 421 and the mounting plate 411. The vibration damping spring 5 is sleeved on the bolt, and its two ends abut against the bottom of the connecting plate 421 and the top of the mounting plate 411, respectively. During processing, the vibration damping spring 5 can effectively absorb some vibration and prevent vibration from being transmitted to the metal rod to be processed through the feeding guide device 4, thereby further improving the stability of processing.

[0032] Furthermore, the bottom of the connecting plate 421 is provided with a rack 6 that is slidably connected to the mounting base 41. A gear that meshes with the rack 6 is rotatably connected inside the mounting base 41. A control motor 61 that controls the rotation of the gear is mounted on the outside of the mounting base 41. The gear is coaxially fixed on the output shaft of the control motor 61. In application, the height of the guide plate 42 can be adjusted according to the different diameters of the metal rod being processed, so that the axis of the V-shaped guide groove 43 is aligned with the extrusion center line between the two thread rolling wheels 3. Thus, when the metal rod is located in the V-shaped guide groove 43, the axis of the metal rod is always aligned with the center line of the thread rolling wheel 3.

[0033] In addition, the connecting plate 421 is provided with a roller brush cylinder 7 at the front end of the guide plate 42, and the inner arm of the roller brush cylinder 7 is provided with elastic brush strips 71. During the feeding process, the dust and oxide scale on the surface of the metal rod are cleaned, and impurities are prevented from being carried into the thread rolling wheel 3, which protects the thread rolling wheel 3 and ensures the surface quality of the metal rod.

[0034] A positioning assembly 8 is provided between the mounting base 41 and the worktable 2 to limit the feeding depth of the metal rod. The positioning assembly 8 includes a positioning block fixed to the bottom of the mounting base 41 and a positioning screw 81 rotatably connected to the worktable 2. The positioning block has a square structure and is slidably connected to the worktable 2, and the positioning block is threadedly connected to the positioning screw 81. To facilitate the selection of the positioning screw 81, a handle 82 is provided at the operating end of the screw. By rotating the positioning screw 81, the positioning block is driven to move along the feeding direction, thereby adjusting the limiting position of the feeding and achieving safe positioning when processing metal rods of different lengths.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
