Abstract
An electromagnetic heating drawbench relates to equipment for drawing molding of a rough pipe casting and is designed to mainly solve low service life of a mold of existing equipment for drawing molding of rough pipe castings. The electromagnetic heating drawbench comprises a soleplate. A rear framework is fixed on the soleplate. A front framework is fixed on the soleplate in front of the rear framework. An external mold is installed on the front framework. An internal mold is arranged inside the external mold. A mandrel of the internal mold is fixed to the rear framework through a nut. Rod ends of two oil cylinders are both fixed to the front framework. Body ends of the two oil cylinders are both connected and fixed with stay tube seat-boards, the middle parts of which are provided with holes. A medium frequency heating device is arranged on the soleplate behind the rear framework. A heating ring support is arranged on the soleplate between the front framework and the rear framework. A heating ring is arranged on the heating ring support. The other end of a wire of the medium frequency heating device is connected with the heating ring. The invention has the following advantage: service life of a mold is prolonged.
Description
Technical field:
The present invention relates to a kind of by equipment shaping for shell draw.
Background technology:
Existing is all that shell carries out draw in the cold state when being worked by equipment shaping for shell draw, owing to needing very large cold-drawn power during cold-drawn, so very violent to die wear, has a strong impact on the mold use life-span.
Summary of the invention:
Technical problem to be solved by this invention is to provide one can reduce cold-drawn power, thus extends the Electromagnetic Heating drawbench of die life.
Above-mentioned purpose is achieved in that it comprises soleplate, soleplate is fixed with afterframe, the soleplate in afterframe front is fixed with front baffle, front baffle is equipped with external mold, have internal mold in external mold, the core bar of internal mold is fixed on afterframe by nut, and the cylinder boom end of two oil cylinders is all fixed on front baffle, the cylinder ends of two oil cylinders is all connected and fixed with trombone slide seat board, has the hole passed through for steel pipe in the middle part of trombone slide seat board; It is characterized in that: on the soleplate at afterframe rear, establish frequency heating device, the basis between former frame frame and afterframe is established heating collar support, heating collar is placed on heating collar support, and the cable other end of frequency heating device is connected with heating collar.
Advantage of the present invention is: owing to having set up heating collar, and shell carries out draw in a heated state, so can reduce cold-drawn power, thus extends the mold use life-span.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is working state schematic representation of the present invention, and in figure, 14 is shells.
Detailed description of the invention:
With reference to Fig. 1, it comprises soleplate 9, soleplate is fixed with afterframe 10, the soleplate in afterframe front is fixed with front baffle 13, front baffle is equipped with external mold 4, in external mold, has internal mold, the core bar 12 of internal mold is fixed on afterframe by nut 7, cylinder bar 3 end of two oil cylinders 2 is all fixed on front baffle, and the cylinder ends of two oil cylinders is all connected and fixed with trombone slide seat board 1, has the hole passed through for steel pipe in the middle part of trombone slide seat board 1; It is characterized in that: on the soleplate at afterframe rear, establish frequency heating device 8, the basis between former frame frame and afterframe is established heating collar support 11, heating collar 5 is placed on heating collar support, and cable 6 other end of frequency heating device is connected with heating collar.
