Unreeling and shearing device for bolt machining

Abstract

The invention discloses an unreeling and shearing device for bolt machining. The unreeling and shearing device for bolt machining comprises a base, a feed rack, an unreeling mechanism, a shearing mechanism, a collection barrel and a control mechanism. The unreeling mechanism comprises a feeding roller couple, a conveying block and straightening roller couples. The shearing mechanism comprises a shearing workbench, a fixed platform, a cutter, a connecting sliding block and a driving cylinder. The connecting sliding block can be driven by the driving cylinder to vertically slidably mounted on the sidewall of the fixed platform. The cutter is arranged below the connecting sliding block. Through mutual cooperation of the feeding roller couple, the conveying block and the straightening roller couples, a wire rod is ensured not to deflect through a locating through hole in the conveying process. The wire rod is straightened through the straightening roller couples. The surface smoothness andthe size uniformity of the wire rod are improved. Convenience is provided for subsequent machining. The machining quality of bolts is improved. The rejection rate is reduced. The working efficiency is improved. Through mutual cooperation of a meter counter and the cutter, the unreeling and shearing device for bolt machining meets the requirement for machining of bolts with different lengths, is accurate in shearing and increases the material utilization rate.

Description

【Technical field】 [0001] The invention relates to the technical field of bolt processing, in particular to an unwinding and shearing device for bolt processing. 【Background technique】 [0002] When processing bolts, it is necessary to unwind the coiled steel first, and then cut it into an appropriate length for subsequent processing. These metal coils are not only heavy in tonnage, but also large, and manual operation is neither convenient nor efficient. Safety. After the coiled steel is purchased, there are problems such as uneven diameter and uneven surface. The existing unwinding device often does not have the function of straightening. If it is directly uncoiled and cut, it will affect the processing quality of subsequent bolts, and in severe cases, the product will be scrapped. , waste resources, reduce production efficiency, and the existing unwinding device, because the diameter of the inner circumference of the coil itself is different, it will often slip when it is...
