Description

Technical Field

[0001] The utility model relates to the technical field of bolt processing, in particular to a buffer-type high-efficiency bolt thread rolling machine. Background Art

[0002] During the production of bolts, the workpiece is first die-casted by a die-casting machine and then threaded. However, during the die-casting process, the workpiece is easily bent. If the bent workpiece is directly lost, the production cost will increase. Therefore, before threading the formed workpiece, the workpiece needs to be straightened before subsequent operations can be carried out.

[0003] The Chinese patent publication number CN213379055U states: A thread rolling machine for bolt processing, comprising a base, the top of which is provided with a feeding structure, a thread rolling structure and two material collection boxes in sequence from top to bottom. The feeding structure and the thread rolling structure are both arranged tilted from top to bottom. The height of the feeding structure is higher than that of the thread rolling structure and corresponds to the thread rolling structure. A driving structure is provided at the bottom of the feeding structure. The thread rolling structure includes a feeding trough, a dividing plate and a reciprocating screw rod. The thread rolling structure includes two fixed troughs, two dynamic thread rolling plates and a static thread rolling plate.

[0004] Although the above-mentioned comparative document relies on an inverted T-shaped feed trough and a dividing plate to sort the blanks, ensuring that only one blank enters the wire rolling structure at a time, thereby improving the wire rolling effect, the wire rolling machine in the above-mentioned comparative document cannot straighten the workpiece and does not have a buffer. If wire rolling is performed directly, the workpiece will not be fully rolled, resulting in product scrapping.

[0005] Therefore, improvements are made to address the above problems. Utility Model Content
