Continuous machining punching device for large-batch nut production

Abstract

The invention discloses a continuous machining punching device for large-batch nut production. The continuous machining punching device comprises a base. The two sides of the upper end of the base areconnected with supporting frames. The upper ends of the supporting frames are connected with a sliding sleeve. A sliding block is arranged in the sliding sleeve. The middle portion of the sliding block is provided with a rotation screw. A drive motor is fixed to the left side of the upper end of the base. The right end of the drive motor is connected with a drive shaft. The right end of the driveshaft is connected with a roller. An inclined sliding way is arranged at the middle portion of the outer side of the roller. A running pulley is arranged at the middle portion of the inclined slidingway and the middle portions of straight sliding ways, the upper end of the running pulley is connected with a pull rod, the right end of the pull rod is connected with a clamping block, and the rightend of the roller is connected with a drive gear. The upper end of the drive gear is connected with a transmission gear. A rotation shaft is connected to the middle portion of the transmission gear.The upper end of the rotation shaft penetrates the workbench and is connected with a machining die. Through the continuous machining punching device, rotary punching of a nut block in the machining die is achieved, the situation that one punching hydraulic cylinder can only punch one station is avoided, the continuous punching requirement is met, the large-batch nut machining requirement is met, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of nut production, in particular to a continuous processing and drilling device for mass production of nuts. Background technique [0002] A nut is a nut, a part that is screwed together with a bolt or a screw for fastening. A screw block that must be used in all manufacturing machinery is divided into carbon steel, stainless steel, and non-ferrous metals (such as copper) according to different materials. Nuts are parts that tightly connect mechanical equipment. Nuts and bolts of the same specification can be connected together through internal threads. For example, M4-P0.7 nuts can only be connected with M4-P0.7 series bolts. (In the nut, M4 means that the inner diameter of the nut is about 4mm, and 0.7 means that the distance between two thread teeth is 0.7mm); the same is true for American products, for example, a 1 / 4-20 nut can only be used with a 1 / 4- 20 screw matching (1 / 4 finger nut inner diameter is...

Problems solved by technology

[0004] In the current processing of common nuts, it is usually divided into two processing procedures. First, holes are drilled on the pre-processed screw blocks, and the screw blocks after drilling are then tapped to form nuts. During the nut drilling process, the efficiency is relatively low. Generally, one hydraulic punching is only carried out for one station. The continuity is poor, which cannot meet the needs of large-scale nut processing, and the practicability is not strong.
