Description

Technical Field

[0001] This application relates to the field of bolt processing technology, and more specifically, to a thread rolling plate for a thread rolling machine for bolt processing. Background Technology

[0002] A thread rolling machine is a device that uses two thread rolling plates to roll threads on a bolt blank. The main working principle of a thread rolling machine is that the screw to be processed is placed in the thread rolling station. Under the driving force of the drive device, the thread plates squeeze the screw to form threads or wire mesh patterns on the screw. After processing, the screw falls from the discharge port into the collection box for collection.

[0003] A thread rolling die is a tool used on a thread rolling machine to roll threads using the plastic deformation of metal. It is suitable for processing ordinary bolts and high-strength bolts. For example, Chinese Patent 201921337036.3 discloses a thread rolling die, including a stationary die and a moving die. A gap is formed between the stationary die and the moving die for the passage of a screw blank. The moving die is equivalent to the movement of the stationary die. The end of the stationary die facing the moving die has a first thread, and the end of the moving die facing the stationary die has a second thread. The end of the stationary die facing the moving die has a first fixed groove, and the end of the moving die facing the stationary die has a second fixed groove. The end of the first fixed groove away from the moving die has a first knurled thread, and the end of the second fixed groove away from the stationary die has a second knurled thread. When the stationary die and the moving die process the screw blank, the two ends of the screw blank head are respectively embedded in the first fixed groove and the second fixed groove.

[0004] However, when a thread rolling board is used for thread rolling, the debris it produces can easily get stuck in the gaps between the threads, requiring regular cleaning, which is time-consuming and laborious. Utility Model Content

[0005] To address the aforementioned problems, this application provides a thread rolling plate for a thread rolling machine used in bolt processing.

[0006] The thread rolling plate of the thread rolling machine for bolt processing provided in this application adopts the following technical solution:

[0007] A thread rolling plate for a thread rolling machine for bolt processing includes a stationary thread plate and a movable thread plate. A thread rolling gap is formed between the stationary and movable thread plates to allow screw blanks to pass through. The movable thread plate reciprocates relative to the stationary thread plate. Thread rolling threads are provided on the opposing surfaces of the stationary and movable thread plates. A first cleaning brush is fixedly connected to one end of the stationary thread plate, and a second cleaning brush is fixedly connected to the opposite end of the movable thread plate. The bristles of the first and second cleaning brushes are arranged opposite each other and contact the thread rolling threads of the stationary and movable thread plates, respectively. When the movable and stationary thread plates perform thread rolling actions, the first and second cleaning brushes clean the thread rolling threads they face.

[0008] Furthermore, a brush plate connecting frame is provided between the first cleaning brush and the stationary tooth plate, and a feeding channel is provided between the brush plate connecting frame and the stationary tooth plate.

[0009] Furthermore, the brush plate connecting frame is inverted L-shaped, and the first cleaning brush is detachably fixed to the side of the vertical end of the brush plate connecting frame by screws, and the horizontal end of the brush plate connecting frame is detachably fixed to the top surface of the stationary tooth plate by screws.

[0010] Furthermore, a T-shaped strip is provided on the inner side of the second cleaning brush, and a slot matching the T-shaped strip is provided at one end of the movable tooth plate. The second cleaning brush is detachably mounted on the movable tooth plate through the insertion structure of the T-shaped strip and the slot.

[0011] Furthermore, the stationary tooth plate has a first chip removal groove vertically formed at the end where the first cleaning brush is located.

[0012] Furthermore, the movable tooth plate has a second chip removal groove vertically formed at the end where the second cleaning brush is located.

[0013] Furthermore, both the first and second cleaning brushes have stiff bristles.

[0014] Furthermore, the bristle length of the first and second cleaning brushes is 1-5 mm longer than the filament gap.

[0015] Furthermore, the vertical length of the first and second cleaning brushes is the same as that of the filament thread.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] This application achieves self-cleaning during the filament rolling process by having the bristles of the first and second cleaning brushes arranged opposite each other and in contact with the thread rolling patterns of the stationary and moving tooth plates, respectively. When the moving and stationary tooth plates are performing the filament rolling action, the first and second cleaning brushes clean the thread rolling patterns they face, thereby eliminating the need to stop the machine for cleaning and further improving production quality and efficiency.
