The self adaptation spinning machine of thin plate spinning machine
[technical field]
The present invention relates to the thin plate spinning machine that thin metal blank in a kind of mechanical molding field is shaped by the deformation of exerting pressure, furtherly be the self adaptation spinning machine of thin plate spinning machine.
[background technology]
Existing spinning machine generally adopts the ironed plate of roll wheel assembly immediate roof on the spinning machine, so that thin plate can be according to pre-designed mold profile generation deformation.Because the driver of driving rolls assembly moves by the programme-control of extraneous controller and has error, the roller cutter track route is not unique, roller cutter when exerting pressure with thin plate be rigid contact and each thin plate between variable thickness, the thin plate that has is thicker, the thin plate relative thin that has is a little, like this so that roller cutter when pressing thicker thin plate on the top roll wheel assembly stressed large, vibrations occur easily and cause and pressed the surface of the work out-of-flatness, simultaneously roller cutter easy damaged distortion.For this reason, need to improve the spinning machine on the existing thin plate spinning machine, need with fast and easy, High-efficient Production.
[summary of the invention]
The present invention has overcome above-mentioned technical deficiency, but the spinning machine of the thin plate spinning machine that a kind of simple in structure and self adaptation adjusts is provided.
For achieving the above object, the present invention has adopted following technical proposal:
The self adaptation spinning machine of thin plate spinning machine, it is characterized in that including pedestal and be installed on the pedestal can before and after the slide plate that slides, described pedestal is provided with for the preloading spring of pushing tow slide plate outward, is equipped with on the slide plate be used to the roll wheel assembly of exerting pressure;
Described pedestal is provided with the groove of strip, and described slide plate active card is enclosed within the above-mentioned groove, and the nose is stretched out outside the groove and linked to each other with described roll wheel assembly;
Described slide plate the inner is provided with the spring top board, and described preloading spring one end top is pressed on the spring top board, and the preloading spring other end is sleeved on the inner set spring mandrel outer of described groove;
The slot opening place of described slip is installed with a pressing plate, pressing plate is provided with along the stopper slot of slide plate slides trend, be provided with on the described slide plate be used to the backstay that limits its moving range, the backstay front portion be inserted in the above-mentioned stopper slot and can be in the stopper slot scope parallel;
Be installed with plate in the described groove, plate is provided with along the chute of slide plate slides trend, and described slide plate is provided with slide rail, and slide rail is fastened in the above-mentioned chute;
Described roll wheel assembly includes fixed axis, is installed in roller housing free to rotate on the fixed axis, and the tight cover of roller housing excircle has cushion rubber, and described fixed axis is fixedly mounted on described nose.
The invention has the beneficial effects as follows:
1, roll wheel assembly is installed on the slide plate, slide plate forms a pretightning force by preloading spring, when thicker metallic plate was pressed on the top, the excessive then preloading spring of the reaction force that the cushion rubber on the roll wheel assembly is subject to suitably shrank with cushion idler assembly and metal sheet active force each other; When a little metallic plate of relative thin is pressed on the top, preloading spring then suitably launches so that roll wheel assembly has enough exerting pressure to carry out mould pressing processing, make that active force remains in the preloading spring elastic force scope between roll wheel assembly and the metal sheet, realize the self adaptation adjustment function of spinning machine, avoid extention effect power and rigid contact to the infringement of roll wheel assembly and metal sheet;
2, be tightly placed in outside the rotating roller housing owing to cushion rubber, exerted pressure in metal edges of boards rotation limit, exert pressure the time thereby greatly save, and the counterrotating metal sheet of cushion rubber does not slide when exerting pressure, and has avoided the Fast Wearing of cushion rubber.

[specific embodiment]
As shown in the figure, the self adaptation spinning machine of thin plate spinning machine, include pedestal 1 and be installed on the pedestal 1 can before and after the slide plate 2 that slides, pedestal 1 is provided with for the preloading spring 12 of pushing tow slide plate 2 outward, is equipped with on the slide plate 2 be used to the roll wheel assembly 3 of exerting pressure.
Among the present invention, pedestal 1 is provided with the groove 11 of strip, slide plate 2 active card are enclosed within the above-mentioned groove 11, be provided with in the groove 11 for the preloading spring 12 of pushing tow slide plate 2 outward, slide plate 2 the inners are provided with spring top board 23, groove 11 the inners are threaded with the screw rod of spring plug 15, and preloading spring 12 1 ends top is pressed on the spring top board 23, and preloading spring 12 other ends are sleeved on outside the spring plug 15.Slide plate 2 front ends stretch out pedestal 1 and are externally connected be used to the roll wheel assembly 3 of exerting pressure.Roll wheel assembly 3 includes fixed axis 31, is installed in roller housing free to rotate on the fixed axis 31 32, and the tight cover of roller housing 32 excircles has cushion rubber 33, fixed axis 31 to be fixedly mounted on slide plate 2 front ends.In order to ensure the rotating effect of roller housing 32, also be provided with rolling bearing 34 between roller housing 32 and the fixed axis 31 among the present invention.
Stability when sliding in order to improve slide plate 2 is installed with plate 13 in groove 11, plate 13 is provided with the chute 131 that slides and move towards along slide plate 2, and slide plate 2 is provided with slide rail 21, and slide rail 21 is fastened in the above-mentioned chute 131.Groove 11 opening parts are installed with a pressing plate 14, pressing plate 14 is provided with the stopper slot 142 that slides and move towards along slide plate 2, screw thread is connected be used to the backstay 22 that limits its moving range on the described slide plate 2, backstay 22 front portions be inserted in the above-mentioned stopper slot 142 and can be in stopper slot 142 scopes parallel.
As shown in Figure 1, the present invention is installed on the driven unit during use, thereby driven unit is used for driving pedestal 1 moves drive roll wheel assembly 3 top pressures metal sheet to be processed as all around, the slide plate 2 that roll wheel assembly 3 links to each other forms a pretightning force by preloading spring 12, when thicker metallic plate was pressed on the top, the excessive then preloading spring 12 of the reaction force that the cushion rubber 33 on the roll wheel assembly 3 is subject to suitably shrank with cushion idler assembly 3 and metal sheet active force each other; When a little metallic plate of relative thin is pressed on the top, 12 of preloading springs suitably launch so that roll wheel assembly 3 has enough exerting pressure to carry out mould pressing processing, make that active force remains in the preloading spring 12 elastic force scopes between roll wheel assembly 3 and the metal sheet, realize that self adaptation of the present invention adjusts function.
