Problems solved by technology

The advantages of this method are simple structure, high precision, easy control, and low manufacturing and use costs. The disadvantages are: the driving torque of the servo motor is small, and the demoulding force generated is small. To obtain greater demoulding force, a large mold must be used. Powerful servo motor, so that the equipment structure is too large, increasing the cost
If the above two methods are not used, the ordinary oil cylinder can be used directly, and the workpiece can be ejected directly to demould, but the cavity of the mold cannot be automatically controlled, and it cannot be applied to the automatic cold press.

Embodiment 1

[0013] Embodiment one: see figure 1 , in the figure, 1-servo motor; 2-coupling; 3-servo motor bracket; 4-electromagnetic clutch; 5-ball screw; 6-screw nut; 7-hydraulic cylinder mounting bracket; 8-ring hydraulic cylinder ;9-piston rod of annular hydraulic cylinder; 10-upper fixed beam; 11-movable platen of female mold; 12-upper guiding column; 13-negative mold; 14-lower die; ; 17-lower fixed beam, 18-frame.

[0014] The automatic loading and demoulding device of the constant volume automatic cold press is a kind of loading and demoulding device for pressing workpieces composed of ordinary annular hydraulic cylinders and servo motors. It includes: an upper fixed beam 10, a lower fixed beam 17, an upper guide column 12 and a lower guide column 16 connecting the upper fixed beam 10 and the lower fixed beam 17, a hydraulic cylinder mounting bracket equipped with a demoulding pull rod 15 and an annular hydraulic cylinder 8 7. The servo motor 1 connected to the lower fixed beam 17...

Embodiment 2

[0016] Embodiment 2: This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the hydraulic cylinder is an ordinary hydraulic cylinder, and its quantity is more than two, and it is evenly distributed along the circumference to form a ring cloth. The upper end of the ball screw can extend into the center of the ring surrounded by all the ring hydraulic cylinders; all the hydraulic cylinders are connected in series or in parallel to realize linkage.

Abstract

The invention discloses an automatic charging and demoulding device of a volumetric automatic cold press. A frame is provided with an upper fixed crossbeam and a lower fixed crossbeam. The upper fixed crossbeam and the lower fixed crossbeam are provided with a lower guide pole and an upper guide pole. A hydraulic cylinder installation bracket is sleeved and fixed on the lower guide pole. A femaledie movement bedplate is sleeved and fixed on the upper guide pole. The female die movement bedplate and the hydraulic cylinder installation bracket are connected by a demoulding pull rod. The lower fixed crossbeam is equipped with a servo motor. The hydraulic cylinder installation bracket is equipped with a hydraulic cylinder. The servo motor is connected with a lower end of a ball screw by a shaft coupling and an electromagnetic clutch. An upper end of the ball screw and a feed screw nut which is installed on the hydraulic cylinder installation bracket form a screw pair. The automatic charging and demoulding device of the volumetric automatic cold press has novel design and reasonable structure, can provide high knockout press and ensure charging precision, is in particular fit for the automatic cold press with high precision and high knockout press and has good economic benefit after popularization.

Description

1. Technical field: [0001] The invention relates to a loading and demoulding device for a diamond product segment, in particular to an automatic loading and demoulding device for a fixed-volume automatic cold press. 2. Background technology: [0002] At present, there are two forms of loading and demoulding of diamond product segments after being pressed on a fixed-volume automatic cold press. One is to use hydraulic servo control to control the volume of the cavity. Eject the workpiece out of the mold. The advantages of this method are: high loading accuracy and large demoulding force. The disadvantage is that the hydraulic servo structure is complicated, the control is complicated, and the manufacturing and use costs are high. The other is to use servo motor control to drive the movable platen equipped with the female mold to adjust the cavity of the material. After pressing, the servo motor drives the movable platen equipped with the female mold to go down, and the lower ...
