There three types of 630tons friction press  J53-630A, J53-630B, J53-630D

  I. Operation mode of J53-630A is inserting type, simple platform, and gantry brake.
II. J53-630B makes improvement basing on J53-630A. Its operation mode is cylinder operation installed at the two ends of transmission axis. Features steel structure platform, push-type brake, flexible and reliable operation. Steel structure platform reduces working voice greatly. Small damage to friction belt for its large brake moment since even contact between brake board area and flywheel. It prolongs friction belt lifetime. So push-type brake is convenient for adjustment.
III. J53-630D makes further improvement basing on J53-630B, maintains advantages of J53-630B, cylinder operation, steel structure platform, push-type brake, whole pre-stress rack. It is new product that our company promotes first. All parts are almost same as J53-630B. Install tension rod basing on J53-630B rack and adopt hydraulic tighten, a new technology to ensure even tightening force. Increase rack intension and rigidity solve rupture problems that exist in J53-630A and J53-630B. So J53-630D press rack enhances its reliability greatly. Intensify overload capability during application. Presently, it becomes the first choice for customers.

There are two specs for 1000 tons friction press J53-1000B, J53-1000C

    J53-1000B is whole machine while J53-1000C is fission which structure is three pre-stress four tension rods, safer than J53-1000B, the whole machine, and solves rupture problem that exists in J53-1000B machine rack.Rack security and reliability of J53-1000C improved much more. Adopt auxiliary board structure which reduces particular stress greatly during flywheel operation so the flywheel runs stable. Change screw and nut from tooth shape into trapezia (J53-1000B screw and nut are square tooth). J53-1000C screw diameter φ400, J53-1000B, screw diameter φ380. Increase lifetime of J53-1000C screw, nut, back-up screw and improve screw rigidity. Brake device changed from J53-1000B gantry brake to J53-1000C push brake which improves reliability effectively and convenient for adjusting. Platform designed rigidity reduces vibration noise during the press working efficiently. J53-1000C slider, supporting back material casting iron (J53-1000B is ductile iron) Besides, slider weight of J53-1000C is more heavier than J53-1000B for 1,000kg, J53-1000C rack column width of front-rear,1000mm, is wider than J53-1000B’s width, 750mm, for 250mm. J53-1000C machine weight is 46.8tons, while, J53-1000B is 38.5tons. Beating force of J53-1000C is stable. Increase stability and reliability effectively. Meanwhile, J53-1000C utilizes cylinder operation at the both ends (J53-1000B using inserting operation), so it’s flexible and reliable. In addition, designed automatic lubricating system makes sufficient and reliable for lubricating.Adopt advanced rack technology of similar product of Germany Harson Company in J53-1000C. It’s the most advanced and reliable structure for present friction press.J53-1000C design focuses on appearance design. Its appearance structure is more reasonable than J53-1000B and more beautiful.

Adopt international advanced structure form in the rack of J53-1000C with 16,000kN double friction screw press which is separated parts four tension rod pre-stress structure. Its design absorbs Germany advanced technology. Main features are strong rack intensity and rigidity. Solve rack rupture problem existed in J53-1000A and lifetime of J53-1000C. Its reliability superior to J53-1000A. J53-1000C is an updated type basing on J53-1000A. It adopts the part of J53-1000A except peculiar parts. Besides, all of its standard parts are universal. In addition, improved design for platform, brake and balancing bar makes simple maintenance. Adopt wearable plate in rack guideway of J53-1000C, which settles bad wearable performance and precision problem that existed in J53-1000A Meanwhile, the push brake of J53-1000C makes flexible and convenient adjustment. Platform design which improves rigidity enhances more stability for the press and reduces noise. Designed automatic lubricating system makes sufficient and reliable for press’s lubricating
   Basic parameters of J53-1000C with 16,000 tons double disc friction screw press are completely same as J53-1000A, electric control, and same operation.J53-1000C fission rack mainly consists of back seat, beam, column (two), tension rod (four), tension rod nut (eight) totally 58 tons. Weight of J53-1000A is 42 tons. Other parts’ weight are same. Total weight of J53-1000C press is 106 tons.

Two Specs of 1000tons friction Brick Molding Press J93-1000B, J93-1000C

  J93-1000B is whole machine while J93-1000C is fission which structure is three pre-stress four tension rods, safer than J93-1000B, the whole machine, and solves rupture problem that exists in J93-1000B machine rack.Rack security and reliability of J93-1000C improved much more.
