Spring end circumferential full-round-corner machining device and machining method

Abstract

The invention relates to a spring end circumferential full-round-corner machining device and a machining method, wherein the device comprises a housing; the housing is movably provided with a motor Aand a motor B in a spaced manner; the motor A is in driving connection with an upper rotating shaft; the motor B is in driving connection with a guide shaft; the housing is provided with a guide groove A and a guiding groove B; the upper rotating shaft penetrates through the guide groove A and can move along the track of the guide groove A; the guide shaft penetrates through the guide groove B andcan move along the track of the guide groove B; the housing is fixedly provided with a gear plate; the gear plate is provided with a gear section; the guide shaft is fixedly provided with a gear B; the upper rotating shaft is rotationally provided with a gear A; the gear A is correspondingly engaged with the gear section and the gear B; the upper rotating shaft is axially connected with a grinding wheel; the periphery of the grinding wheel is concavely provided with a circle or arc-shaped notch; and the end part of a plate wire material can be subjected to circumferential full-round-corner grinding via the arc-shaped notch. The device and the method provided by the invention realize full-automatic production and can also improve the product precision, lower the cost and improve the efficiency.

Description

technical field [0001] The invention relates to the field of rounded corner processing, in particular to a device and method for processing rounded corners in the circumferential direction of spring ends. Background technique [0002] In the actual product production, there are edges and corners at the end of the plate wire (the end face of the plate wire is square, with edges and corners), which will cause hidden dangers that affect the quality and safety of the product (such as a spring made of plate wire). Therefore, in order to solve For the above technical problem, it is necessary to process the ends of the plate and wire with full rounded corners in the circumferential direction, so that the ends of the plate and wire have full rounded corners in the circumferential direction, such as figure 1 and figure 2 shown. However, due to the shape of the end of the plate wire, it cannot be directly ground into shape by the existing grinder (the existing grinder can only grin...

Problems solved by technology

[0002] In actual product production, there are edges and corners at the end of the plate wire (the end face of the plate wire is square and has edges and corners), which will cause hidden dangers that affect the quality and safety of the product (such as a spring made of plate wire). Therefore, in order to solve For the above technical problem, it is necessary to process the ends of the plate and wire with full rounded corners in the circumferential direction, so that the ends of the plate and wire have full rounded corners in the circumferential direction, such as figure 1 and figure 2 shown

However, due to the shape of the end of the plate wire, it cannot be directly ground into shape by the existing grinder (the existing grinder can only grind circular wire with a circular cross section), so it is urgent to design a A device for rounding the ends of wire rods in the circumferential direction
