Description

TECHNICAL FIELD

[0001] The utility model relates to bolt thread rolling machine automatic feeding technical field, specifically to a kind of bolt thread rolling machine automatic feeding device. BACKGROUND

[0002] Bolt is a very common metal connecting piece, which is made of metal bar as raw material, and is sequentially subjected to length cutting, end upsetting forming, surface shot blasting and thread rolling processing steps. During the thread rolling processing, the feeding device is needed for conveying and arranging to facilitate one-time thread rolling processing.

[0003] For example, the utility model disclosed in Chinese patent CN214651347U belongs to the technical field of industrial equipment, and is a conical vibration blanking disc, which comprises a fixed base, a fixed bottom plate is welded to the outer surface of the fixed base, a hole slot is formed in the inner side surface of the fixed bottom plate, a vibration cylinder is fixedly installed on the upper end surface of the fixed base, a feeding channel is welded to the inner side surface of the blanking outer baffle, an inner baffle is welded to the upper end surface of the feeding channel, and a limiting piece is welded to the outer surface of the inner baffle. The utility model can fix the position of the fixed base by setting the fixed bottom plate and the hole slot, thereby avoiding the position deviation of the blanking disc after use, ensuring accurate feeding of the discharge channel, and ensuring smooth progress of the work process. By setting the limiting piece, the excess material accumulated on the feeding channel is removed when the material passes through, so that the material can pass through the feeding port in an orderly manner, the material is prevented from accumulating at the feeding port, and the material can pass through the discharge channel normally. However, in order to ensure the stable conveying of the bolt, the limiting mechanism on both sides of the guide frame corresponds to the specification of the bolt in the traditional bolt feeding device, but the limiting structure is mostly integrally connected with the guide frame. When the conveying screw specification changes, the limiting structure cannot be adjusted according to the bolt specification, and only the entire device can be replaced, which has certain limitations during use and greatly increases the working time. Therefore, a bolt thread rolling machine automatic feeding device is proposed to solve the above problems. UTILITY MODEL CONTENTS
