Abstract
The invention discloses a heat gain forming device for high-strength steel plates and belongs to the field of mechanical engineering. The heat gain forming device for the high-strength steel plates is used for achieving plastic machining on high-strength plates. The high-strength steel plates are difficult to form and machine at normal temperatures because the high-strength steel plates are high in strength and good in toughness; therefore, the high-strength steel plates can be heated in advance in the process of forming. The heat gain forming device for the high-strength steel plates can be applied to forming of the high-strength steel plates. Based on various characteristics of the high-strength steel plates, medium-high frequency induction heating devices are arranged around a tool. The heat gain forming device for the high-strength steel plates can heat the preformed high-strength steel plates to a certain temperature, and therefore the high-strength steel plates can be formed more easily.
Description
Technical field
Plate increment building mortion is sheet material to be carried out to the equipment of plastic working, belongs to field of machining.
Background technology
Stamping is the important method of plastic working, in modern industry, is used widely.But stampingly often need diel, its process-cycle and manufacturing cost are all higher, for single batch of small lot and trial production of new products, can realize that the flexible die of partial plastic forming just seems particularly important.
It is to adopt simple mould plate to be carried out to a kind of technique of successively plastic working that the plate increment is shaped, and does not need the special-purpose mould comparatively part of complexity that just can be shaped, and is a kind of flexible plastic processing method.Normally on Digit Control Machine Tool, carry out, requirement according to sheet forming process, work out out the control program of Digit Control Machine Tool, utilize the feed system of Digit Control Machine Tool to control the column instrument with bulb, plate progressively is shaped according to given track, finally reach the desired shape of blank, therefore be also referred to as the pointwise increment and be shaped.Plate single-point increment is shaped and has been applied to comprise the production and processing of the parts such as automobile panel, handicraft, soldier-worker product, and development prospect is wide.
But, along with the development of modern industry, the high-strength steel plates such as TRIP steel and dual phase steel are widely applied in national economy is produced.Increment is shaped because deformation load is little, be difficult at room temperature realize the shaping of high-strength steel sheet, and resilience is serious, therefore is badly in need of high temperature increment Forming Equipments.
The present invention proposes just under this background.
Summary of the invention
The present invention proposes a kind of to high strength steel plate high temperature increment building mortion, be called high strength steel plate heat gain building mortion, main by the transformation to bulb column forming tool, around cutter, add the medium-high frequency induction heating apparatus, realize that the heat gain of high-strength steel sheet is shaped.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is punch-head assembly structural representation of the present invention.
In figure: 1. blank holder 2. metal blank 3. medium-high frequency induction heater 4. bulb column forming tool 5. fixture 6. backing plate 7. frames
The above-mentioned purpose of specific embodiment patent of the present invention is achieved in that accompanying drawings is as follows.
Consult Fig. 1: high strength steel plate heat gain building mortion mainly contains upper and lower matrix and forms.Upper matrix mainly is comprised of the bulb column forming tool 4 with medium-high frequency induction heater 3, and lower substrate mainly is comprised of blank holder 1, fixture 5, backing plate 6 and frame 7.
Forming step is: at first that high strength steel plate (Trip steel) 2 use fixtures 5 are fixing, in order to prevent that sheet material from occurring that in forming process the defect such as wrinkling applies pressure-pad-force by blank holder 1, then be coated with one deck graphite at surface of steel plate and play lubrication, to reduce the wearing and tearing of bulb column forming tool 4 in forming process.Adjust the distance of bulb column forming tool 4 and preform high strength steel plate 2, opening 3 pairs of bulb column forming tools 4 of medium-high frequency induction heater is preheated, feedback by 3 pairs of temperature of medium-high frequency induction heater, reach the setting forming temperature and stop heating, and press designed machining locus by the load maintainer loading and shaping according to the geometry of formation of parts.
Claims (1)
1. high strength steel plate heat gain building mortion, it is characterized in that: added the medium-high frequency induction heating apparatus around bulb column forming tool, this device can heat to cutter fast, when being warmed up to predetermined temperature, automatically stop heating, when cutter heats up, the high strength steel plate in the partial plastic forming zone contacted with cutter also heats up thereupon, when the shaped region of high strength steel plate reaches applicable plastic working, by the load maintainer loading and shaping.
