Abstract
The utility model relates to a spring bending device which is characterized by comprising a die block with a groove and a punch matched with the groove. The end, which is matched with the groove, of the punch is arc-shaped. Two ends of a top opening of the groove are arc-shaped. By the spring bending device, scratches of the spring during bending can be avoided, and good quality of the spring can be guaranteed.
Description
Technical field
The utility model relates to a kind of spring apparatus for bending, is widely used in the spring of high-accuracy requirement.
Background technology
Spring is a kind of machine components of accumulation of energy.It impacts or shakes, stores up the size of energy, ergometry etc. in order to motion, the mitigation of controlling parts, is widely used in automobile, locomotive, dynamic power machine, instrument, the instrument.
Have now in making extension spring, the junction of two ends hook need to be carried out bending and be processed, existing technology is for using two opposite cutters of the direction of motion to finish, this technology can cause the scratch after the cutter shearing appears in bending part, most importantly can have influence on spring and the stressing conditions of linking up with the junction, cause spring in drawing process, to produce fracture.
Summary of the invention
The purpose of this utility model is to provide a kind of spring apparatus for bending, and this device can protect spring not produce scratch in bending is processed, and guarantees that spring has the characteristics of Functionality, quality and appealing design.
The technical solution of the utility model is: a kind of spring apparatus for bending is characterized in that: comprise the reeded module of a tool and with the drift of groove fit, described drift and groove fit end are circular-arc, the opening two ends of described groove top are circular-arc.
Further, described bottom portion of groove two ends are circular-arc.
Further, described module and the first slide block one end bolt, described the first slide block cooperates connection with the first slide rail, and the described first slide block other end and a cam mechanism link, and are used for driving the first slide block and slide to drive block motion at the first slide rail.
Further, described drift and the second slide block one end bolt, described the second slide block cooperates connection with the second slide rail, and the described second slide block other end and a cam mechanism link, and are used for driving the second slide block and slide to drive the drift motion at the second slide rail.
The utility model has the advantage of:
1, can protect spring in bending is processed, not produce scratch, guarantee that spring has the characteristics of Functionality, quality and appealing design, improve the service life of spring;
2, structural design is simple, novel, makes and draws materials conveniently, makes simply, and cost is low.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the schematic diagram that module and drift bending are processed.
The specific embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, embodiment cited below particularly, and cooperation accompanying drawing be described in detail below, but the utility model are not limited to this.
With reference to legend, a kind of spring apparatus for bending is characterized in that: comprise one have groove 1 module 2 and with the drift 3 of groove fit, described drift and groove fit end are circular-arc, the opening two ends of described groove top are circular-arc.
Described bottom portion of groove two ends are circular-arc.
Described module and the first slide block 4 one end bolts, described the first slide block cooperates connection with the first slide rail 5, and the described first slide block other end and a cam mechanism 6 link, and are used for driving the first slide block and slide to drive block motion at the first slide rail.
Described drift and the second slide block 7 one end bolts, described the second slide block cooperates connection with the second slide rail 8, and the described second slide block other end and a cam mechanism link, and are used for driving the second slide block and slide to drive the drift motion at the second slide rail.
In the utility model, circular-arc being carried out the result that rounding skids and processes, and can guarantee like this when bending is processed, can not cause " scar " to the iron wire 9 for the manufacture of spring, guarantee the quality of spring, in legend, 1. expression has locates the place of skidding and processing for carrying out rounding.
In the utility model, the cam mechanism that be used for to drive the first slide block and the second slide block can be for the same, also can different mechanism, only draw out the identical situation of two cam mechanisms in the utility model, certainly, also can realize between the two motion with different driving mechanisms.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
