Numerical control upsetting forging press for ejection wires and working method

Abstract

The invention provides a numerical control upsetting forging press for ejection wires and a working method. An ejection mechanism of the numerical control upsetting forging press for ejection wires is driven by an ejection servo motor and arranged on a press body. An integral main die assembly comprises a main die holder, in which a cutting die installation hole and upsetting concave die installation holes are arranged. The working method comprises following steps: feeding, utilizing translation of the integral main die assembly to achieve displacement full-circle cutting; performing upsetting operation and utilizing the ejection mechanism to eject blank or shaped parts. The working method has following beneficial effects: a cutting mechanism is not needed; replacement and adjustment are carried out for parts in the integral main die assembly outside the press body such that upsetting efficiency is increased; and stroke and position adjustments of the ejection mechanism are made conveniently and flexibly.

Description

technical field [0001] The invention relates to a heading machine and a working method of the heading machine. Background technique [0002] The upsetting machine is a device that uses the back and forth movement of the large slider to upset the blank in the main die through the punch. [0003] Upsetting machine is mainly composed of machine body, punch assembly, punch assembly driving mechanism, main mold, ejector mechanism, feeding mechanism and shearing mechanism. [0004] In the traditional upsetting machine, the punch assembly and the die included in the main die are all fixed on the corresponding machine body. The upsetting machine with this structure has many mechanical mechanisms, complex structure, many faults, difficult operation and low upsetting efficiency. , Feeding and discharging are more troublesome. [0005] At present, the one-die two-blow upsetting machine and the multi-die multi-punch upsetting machine are used more frequently to realize the displacemen...

AI Technical Summary

Problems solved by technology

However, the forging machine belongs to the die rotating equipment, therefore, the same blank needs to be forged multiple times in the same die, and even the final completion does not leave a die

However, the upsetting deformation of the same die is limited, so the quality of upsetting is not good, and the ejection is also difficult.

In addition, the upsetting space of the high-speed forging molding machine with this structure is small, which is not convenient for feeding, upsetting and discharging operations.

[0007] In addition, when upsetting the billet, due to the different size requirements of the formed parts, the ejection mechanism needs to adjust its movement stroke according to the requirements of the formed parts. However, the adjustment of the ejection mechanism in the existing upset forging machine is set On the machine body, that is, the adjustment mechanism of the ejector mechanism is located outside the main mold, and the ejection stroke must be adjusted under the premise that the upset forging machine stops working. Therefore, not only the ejection stroke cannot be adjusted flexibly, but also the upsetting forging will be affected. At the same time, it is very inconvenient to adjust the stroke of the ejector

In addition, most of the ejection mechanisms are now mechanical structures. As mentioned above, the length requirements of the formed parts for the upsetting blank are different, so the stroke of the ejection mechanism needs to be adjusted frequently; at the same time, when the upsetting forging After the machine has been working for a period of time, due to the wear of the ejector mechanism, in order to ensure the quality of the formed parts, it is also necessary to adjust the stroke of the ejector mechanism; but no matter what the above situation is, the adjustment of the mechanical ejector mechanism is very troublesome ,not flexible

[0008] For the existing upsetting machines, the dies are all fixed on the machine body. When it is necessary to replace or adjust the dies, the upsetting machine must be stopped before it can be carried out, which also affects the working efficiency of the upsetting machine. , it is also inconvenient to replace and adjust the die
