Description
Technical field
The utility model relates to spring technical field, particularly relates to a kind of spring wire rod shearing device of improvement.
Background technology
At present, the spring wire shearing device of traditional helical spring forming machine, generally comprise cutter mechanism, semicircle mandrel and semicircle mandrel seat, this device is when producing the spring of various outer diameter, need the position constantly regulating cutting knife, the adjustment cutting knife slide block of this device and the spacing mode of idler roller block, must go the length adjusting screw rod, such inefficiency manually.
In order to overcome the above problems, in prior art, there is a kind of wire cutting device of spring forming machine, although improve your operating efficiency that must be, but its cutting knife cam and cutting knife idle pulley are eccentric wheel drive mechanism, because eccentric wheel is single cam, cutting knife cam rotates a circle, cutting knife idle pulley moves up and down once, formed and once cut off, such cut-off velocity is slow, and single cam is easy to wear, and the distance of cutting knife cam and idle pulley is non-adjustable, when after wearing and tearing certain distance, then need a whole set of replacing, therefore cost is high.
Utility model content
The purpose of this utility model is for weak point of the prior art and provides a kind of cutting knife cam to rotate a circle, and make the alternative breaks of cutting knife, efficiency is high, and the adjustable spring wire rod shearing device of the distance of cutting knife cam and idle pulley.
The purpose of this utility model is realized by following technical measures:
A kind of spring wire rod shearing device of improvement is provided, comprise board header board, chute is offered in board header board, Cutter apron is provided with in chute, Cutter apron is provided with cam from top to bottom successively, the idle pulley be connected with cam engagement is provided with below cam, idle pulley lower end is connected with cutting knife, the corresponding semicircle mandrel being provided with linking springs wire rod below cutting knife, described cam is provided with at least three projections, comprising two small embossments and a large projection, the angle of two small embossments is 60 °, the angle of large projection and two small embossments is 150 °, described cam and idle pulley side are equipped with adjustable plate, adjustable plate offers " ten " groove of font.
Wherein, described idle pulley is also connected with slide block, and upper end of slide block is connected with Cutter apron by spring, and slide block both sides are by between guide plate and Cutter apron.
The beneficial effects of the utility model:
The spring wire rod shearing device of a kind of improvement of the present utility model, comprise board header board, chute is offered in board header board, Cutter apron is provided with in chute, Cutter apron is once provided with cam from top to bottom, the idle pulley be connected with cam engagement is provided with below cam, idle pulley lower end is connected with cutting knife, the corresponding semicircle mandrel being provided with linking springs wire rod below cutting knife, described cam is provided with at least three projections, comprising two small embossments and a large projection, the angle of two small embossments is 60 °, the angle of large projection and two small embossments is 150 °, described cam and idle pulley side are equipped with adjustable plate, adjustable plate offers " ten " groove of font, the utility model by being provided with at least three projections distributed at an angle on cam, such cutting knife cam rotates a circle, cutting knife alternative is cut off spring wire, efficiency is high, in addition, described cam and idle pulley side are equipped with adjustable plate, adjustable plate offers " ten " groove of font, the distance of such cutting knife cam and idle pulley can flexible modulation.
