Abstract
A quenching device for forming a band spring belongs to a heat-treating quenching facility. The quenching device comprises a lower crest tooth model, an upper crest tooth model and a clamping oil cylinder associated with the upper crest tooth model. The utility model is characterized in that the lower crest tooth model and the upper crest tooth model are disposed inside a moveable framework, and the moveable framework is connected with a plug rod of a tilting cylinder which is installed on a fixed framework. Employment of a framework-typed structure enables the structure of the utility model to be simple. The utility model is mainly used in manufacturing heavy-typed band spring, the band spring with flat and straight section in the middle portion or other special-shaped band springs and is capable of guaranteeing the quality of band spring after quenching.
Description
Technical field
The utility model belongs to heat-treatment quenching equipment, relates generally to be used for the device that leaf spring is shaped and quenches.
Background technology
Quenching device is the specific equipment of automobile leaf spring manufacturing, and it is that the leaf of spring through heating is pressed into needed shape in advance, and plate spring sheet bending forming and quenching process are finished in cooling rapidly under restrained condition then.In the prior art, the patent No. is ZL94208427.6, denomination of invention is " the vertical quenching device of computer control leaf spring ", a kind of leaf of spring quenching device that can vertically quench is disclosed, this device adopts cantilever design, for the leaf of spring shaping difficulty of the thicker asymmetric complicated shape of the heavy leaf of spring or the left and right sides, and the shape after being shaped is inaccurate; Though it has solved the leaf spring problem of vertically quenching, avoided leaf spring because of cooling off the asynchronous thermal stresses inequality that causes, the Lateral Bending of Leaf Springs phenomenon of bringing, it is still complicated owing to adopt rake formula structure, causes and safeguards inconvenience.
Summary of the invention
The purpose of this utility model provides a kind ofly processes heavy and the complicated shape leaf spring, and leaf spring shaping quenching device simple in structure.
Leaf spring shaping quenching device of the present utility model, comprise following apical tooth mould, the clamping cylinder of going up the apical tooth mould and connecting with last apical tooth mould, it is characterized in that down the apical tooth mould, go up the apical tooth mould and be arranged in the mobile framework that mobile framework is connected with the piston rod of hoist cylinder on being installed in fixed frame.
Apical tooth mould down of the present utility model is fixed on mobile base of frame, and last apical tooth mould is connected with mobile framework by the liner of being made up of orienting sleeve and guidepost.Following apical tooth mould is the arc of projection, the shape of last apical tooth mould and its coupling.Fixed frame is arranged on the outside or the rear side of mobile framework, and mobile framework can move up and down along the guide path on the fixed frame.The piston rod of the compressed oil cylinder on the straight briquetting at last apical tooth mould middle part passes the apical tooth mould and is fixed on mobile framework is connected.
Because the utility model adopts tower structure, easy to make simple, maintaining is convenient; Adopt gantry upright post formula structure, in both sides, last apical tooth mould upper end clamping cylinder is set, be particularly suitable for processing heavy type, the centre has flat segments or other complex-shaped leaf spring, and can guarantee that the leaf spring level falls into quenchant, thereby the thermal stress distribution that the leaf spring cooling is produced is even, avoid Lateral Bending of Leaf Springs, guarantee the quenching quality of leaf spring.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A place section partial enlarged drawing of Fig. 1.
Embodiment
Among Fig. 1, plate spring after the heating is put on the last apical tooth mould 5 and the following apical tooth mould 3 between the following apical tooth mould 3 of quenching device, and be located, compressed oil cylinder 7 drives upward, and the straight briquetting 10 of apical tooth mould 5 intermediary moves down, the neutral straight section of plate spring is compressed, clamping cylinder 6 drives are gone up apical tooth mould 5 and are moved down along guidepost 4, and plate spring is pressed into predetermined shape; At this moment, the piston rod of hoist cylinder 8 drives mobile framework 2 and vertically drops in the quenchant along fixed frame 1, and makes between medium and leaf spring and form relative movement, and leaf spring is cooled off fast, finishes quenching process.According to the technology cooling time that is provided with, compressed oil cylinder 7 drives on the straight briquetting 10 and moves after the leaf spring through hardening, and simultaneously, clamping cylinder 6 drives goes up apical tooth mould 5 along moving on the guidepost 4, on following apical tooth mould was delivered to conveyor chain in the quenching bath, leaf spring changed next procedure over to discharging device 9 with the leaf spring holder.
Among Fig. 2, when mobile framework 2 descended, the guide deflection sheave 11 that is fixed on mobile framework 2 both sides limited its upper and lower vertical movement of guide pillar groove along fixed frame 1, thereby guaranteed that leaf spring level under restrained condition falls into quenchant.
Claims (5)
