Hydraulic Press

JH21 Series C-Frame Fixed Bolster Press

With a dignified and dignified shape structure, delicate and sophisticated paint technology, the ingenious manufacturing technology, the industry's top configuration, the inherent quality of the test for a long time, and the open mentality of excellence, showing the style of TMA Machine's JH21 series pressure machine.

Introduction to Configuration

FEA & Stress Analysis

Stress Analysis & Finite Element Analysis

The CAE software SOLIDWORKS used as the method to analyze the linear static construction, stress and deformation for press break and laser cutting machine frames. So for complicated structures, highly complex loading’s, transient modelling and combination of the above, FEA makes sense.

STRUCTURE AND TABLES

JH21-series C-frame presses consist of an electro welded structure made solely of S355JR steel. They are stabilised and machined at the end of the structural welding process to ensure perfect parallelism and precision. Calculated and designed by finite. With all this, we always guarantee our high precision and quality standards. These models are equipped with a mechanized lower and upper C45E steel table with DIN-650 grooves. The upper table ensures perfect alignment by means of two cylindrical lateral guides of 50 mm diameter with maintenance free anti-friction bimetallic caps.

CYLINDER AND HYDRAULIC UNIT

The cylinder is double acting with a chrome plunger and maintenance-free anti wear guides. Anti-turning of the cylinder with a squared front ant stroke endings come as standard which enable us to conveniently regulate the cylinder stroke.

A two-speed motorized hydraulic unit with automatic high speed deactivation. It’s equipped with a cylinder decompression valve. A pressure switch placed at the lateral part comes as standard which allows the regulation of the most appropriate pressure signal for each kind of pressing.

They are supplied with a glycerin gauge with reading in tonnes.

ELECTRIC INSTALLATION AND SAFETY

The control panel features a switch enabling the user to select the desired type of work in a manual, semi-automatic or automatic position and a switch to select either the fast speed or slow speed. Electrical and hydraulic manoeuvres are redundant and self-controlled. They incorporate an additional safety block and self-control devices for manoeuvre and safety. It includes the verification and certification of the correct operation and the safety distance for the photocells.

Operation is carried out by low voltage electric pedals.

Safety is guaranteed by the use of two lateral protections and with level IV safety light curtains situated at the front.

They allow the installation of a hydraulic cushion or a hydraulic ejector. They are supplied with an instructions manual.

It meets and satisfies all the essential health and safety requirements in accordance with the EC standard.
