Pitch shaper for hot coiled spring

Abstract

The invention discloses a pitch shaper for a hot coiled spring. The pitch shaper comprises a fixing frame (1), a handle (2), five shaping knives (3) which are horizontally uniformly arranged, a support rod (4) and a screw shaft (5), wherein a knife head (31) is arranged at the lower end of each shaping knife (3), five sections of threads, left-handed threads and right-handed threads, are sequentially arranged on the screw shaft (5) from the left part to the right part at intervals, a bolt head (51) is arranged between every two adjacent thread sections on the screw shaft (5), the support rod (4) is made from square steel, the support rod (4) is connected with the fixing frame (1) through welding, a square hole is formed in the upper part of each shaping knife (3), the shaping knife (3) can slide along the support rod (4), and the each shaping knife (3) is connected with the screw shaft (5) by threads; the knife head (31) is in a shape of an inverted cone. The pitch shaper has the advantages of simple structure, convenience in regulation, high spring shaping efficiency, freedom from damaging the surface of the spring and long service life.

Description

technical field [0001] The present invention relates to a spring appliance, in particular to a hot coil spring pitch shaper. Background technique [0002] After the spring is processed by hot coiling, there is often a problem of uneven pitch, and the pitch needs to be trimmed. The existing trimming method mostly uses a shaper with a wedge-shaped cutter head for trimming. This method, on the one hand, due to Only one pitch can be trimmed at a time. The more spring pitches, the longer the trimming time, and the trimming efficiency is low. On the other hand, because the cutter head of the shaper is in the shape of a wedge, it is easy to damage the spring surface and affect the spring quality. Contents of the invention [0003] The purpose of the present invention is to provide a hot coil spring pitch shaper with simple structure, convenient adjustment, high spring-setting efficiency, no damage to the spring surface, and long service life. [0004] In order to achieve the abo...
