Abstract
The utility model relates to locomotive deformed spring hook die, in particular to a die for manufacturing a spring hook. The die mainly solves the problems that the existing method of coiling a spring hook by using a deformed core shaft lathe requires designing a deformed core shaft in advance, the processing and the manufacture are difficult, and the method that the spring hook is manufactured by cold coiling firstly and then pressing through a die is simple, but a pressing die is required to be designed and manufactured, so that the workload is large, and the production period is long. The die adopts the technical scheme that an interference positioning pin and a grinding positioning pin are vertically fixed on a bottom plate in positions where the excircle of the interference positioning pin is in contact with that of a spring and the excircle of the grinding positioning pin is in contact with the inner circle of the spring. In the utility model, the positioning pins are adopt to position the spring, so as to ensure the external dimension of the spring, and reduce the manufacture difficulty of the die, so that the die is simple to manufacture and practical; and the die is applicable to deformed springs with diameters being lower than 4 mm, and has the advantages that the amount of work is small, the production period is short, and the cost is reduced.
Description
Technical field
The utility model relates to a kind of mould of making cold coiling spring, relates to the mould of making the deformed spring crotch specifically.
Background technology
It is that (one) utilizes special-shaped mandrel lathe to roll that the cold coiling deformed spring is made conventional method; (2) pass through mould punching with punch press again behind the first cold coiling; These two kinds of equal more complicated of method, (one) plants the need special-shaped mandrel of design earlier, and processing and manufacturing is difficulty; (2) plants and to roll easily, and it is higher but need design and produce diel to make precision, and workload is bigger, and the production cycle is longer.
Summary of the invention
The purpose of this utility model is the bigger drawback of difficulty of processing that exists at above-mentioned two kinds of methods, and a kind of processing that proposes simply is suitable for, and the workload of making mould is little, with short production cycle, the deformed spring crotch mould that can reduce cost.
Technical solution of the present utility model is: the interference alignment pin of deformed spring crotch mould and mill are repaiied alignment pin and are vertically fixed on the base plate, the fixed position that interference alignment pin and mill are repaiied alignment pin is, the cylindrical of interference alignment pin and the cylindrical of spring are tangent, and it is tangent that mill is repaiied the interior circle of the cylindrical of alignment pin and spring.
Technical solution of the present utility model is the semicircle pin that is shaped as that described mill is repaiied alignment pin, and its diameter limit is on the diameter line of spring.
Technical solution of the present utility model is that described mill is repaiied and is set with a lever spanner that has sleeve on the alignment pin.
Deformed spring crotch mould of the present utility model adopts alignment pin to make the spring location, guaranteed spring appearance and size, reduced the manufacture difficulty of mould, adopt lever principle to make and roll spanner, panel beating worker principle is implemented the spring crotch, and mould is made simple and practical, and applicability is strong, mould adjustment reparation is easy, does not influence production; The utility model is suitable for the following deformed spring of material footpath 4mm, and the workload of making mould is little, with short production cycle, has therefore reduced production cost widely.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, vertical fixing has interference alignment pin 3 and mill to repair alignment pin 4 on base 1, and it is to determine a center of circle O on base 1 that interference alignment pin 3 and mill are repaiied the position that alignment pin 4 is fixed on the base 1, draw a circle with this center of circle O, this diameter of a circle promptly is the diameter of spring 5 to be processed; The position of interference alignment pin 3 on base 1 is that its cylindrical and spring 5 cylindricals are tangent, it is that circle is tangent in its cylindrical and the spring 5 that mill is repaiied the position of alignment pin 4 on base 1, as shown in Figure 2, the shape that mill is repaiied alignment pin 4 is a semicircle pin, the diameter limit of semicircle pin promptly is that the mill of spring 5 is had a shave, and this mill is had a shave on the diameter line of spring 5; The utility model is furnished with a lever spanner 2, and lever spanner 2 is one and is fixed with a sleeve on lever, as shown in Figure 1; When processing profiled spring crotch, with the material embryo of spare spring 5 according to location, position shown in Figure 2 after, sleeve set on the lever spanner 2 is repaiied on the alignment pin 4 at mill, with the material embryo termination that lever spanner 2 plates change spring 5, after the termination that makes spring 5 and the mill of alignment pin 4 were had a shave and be close to, crotch successfully, spring 5 behind the taking-up crotch, by drawing crotch termination length dimension is pruned, last reconditioning termination burr completes.
Claims (3)
1. locomotive deformed spring crotch mould, it is characterized in that interference alignment pin (3) and mill repair alignment pin (4) and be vertically fixed on the base plate (1), the fixed position that interference alignment pin (3) and mill are repaiied alignment pin (4) is, the cylindrical of the cylindrical of interference alignment pin (3) and spring (5) is tangent, and it is tangent that mill is repaiied the interior circle of the cylindrical of alignment pin (4) and spring (5).
2. locomotive deformed spring crotch mould according to claim 1 is characterized in that described mill repaiies the semicircle pin that is shaped as of alignment pin (4), and its diameter limit is on the diameter line of spring (5).
