Problems solved by technology

The steam die forging hammer needs a huge high-pressure steam supply system, and its control is relatively difficult, and the noise generated is relatively large
The electro-hydraulic hammer requires a complex hydraulic system and high manufacturing costs
Whether it is a steam die forging hammer or an electro-hydraulic die forging hammer, its structure is relatively complicated, it occupies a large area, consumes a lot of energy and produces strong noise pollution.

Embodiment approach 1

[0017] Embodiment 1: The composition of the gear die forging hammer includes an anvil, and the anvil is composed of a lower anvil 10, an upper anvil 8, and a shock absorber 9 arranged between the upper and lower anvils. Install the base 23 on the anvil. Body 21 is installed on the base, and connecting plate 18 is arranged on the top of the body. Hammer head 22 links to each other with hammer rod. A driving mechanism is installed on the hammer rod. The drive mechanism includes a casing 17 installed on the top of the body, in which a support 15, a support 13, a motor 14, a reduction box 11, a clutch 16, a gear 12 and a rack 2 are arranged. The hammer rod extends into the box body, and the connection relationship of each part in the box body is as follows: the rack is connected with the hammer rod, the support is installed on the lower part of the box body and the bracket is hinged on the support, the motor and the reduction box are installed on the bracket, and the gear Insta...

Embodiment approach 2

[0018] Embodiment 2: On the basis of Embodiment 1, a cylinder type accelerator 24 is arranged on the top of the box. When the hammer rod is lifted, the air in the cylinder is compressed, and when the hammer head is lowered, the compressed air in the accelerator expands rapidly to achieve the effect of acceleration and boosting and increase the impact force.

Embodiment approach 3

[0019] Embodiment 3: On the basis of Embodiment 1 or 2, a dust-proof pad 3 is provided between the hammer rod and the connecting plate on the body, and a bearing bush or bearing is arranged at the contact part between the hammer rod, the connecting plate and the box body, That is to ensure the flexible movement of the hammer rod, and prevent the dust generated by the blow from entering the bearing bush and other moving parts in the box, so as to reduce wear and improve the service life.

Abstract

A gear-type die forging hammer system is composed of stock, base, machine body, hammer with rod, and drive mechanism consisting of a box on machine body and such units in said box as stand, supporting frame, motor, speed reducer, clutch, gear and rack bar connected with hammer rod. It has low noise.

Description

(1) Technical field [0001] The invention relates to a forging machine, in particular to a die forging hammer. (2) Background technology [0002] Die forging hammer is an important machine for forging. The die forging hammers currently used mainly include steam die forging hammers and electro-hydraulic die forging hammers. The steam die forging hammer needs a huge high-pressure steam supply system, and its control is relatively difficult, and the noise generated is relatively large. The electro-hydraulic hammer requires a complicated hydraulic system, and the manufacturing cost is high. Whether it is a steam die forging hammer or an electro-hydraulic die forging hammer, its structure is relatively complicated, it occupies a large area, consumes a lot of energy and produces strong noise pollution. (3) Contents of the invention [0003] The object of the present invention is to provide a gear die forging hammer with compact structure, low energy consumption and less noise ...
