Problems solved by technology

[0004] However, if the oil pump automatic lubrication system is adopted, due to the different lengths of the oil pipelines from the oil pump to each lubrication point, the oil supply pressure varies greatly, and the packing is not well lubricated, which increases the friction of the hammer rod and causes the hammer body to be strained during movement. Phenomena such as roughening of the guide surface and the trapezoidal guide surface of the hammer body guide groove will eventually shorten the life of components such as packing, hammer rod, cylinder and guide rail
Secondly, from the oil pump to each lubricating point, there are many connection points, which are prone to leakage, resulting in insufficient oil supply and low oil pressure, which further deteriorates the lubrication situation; the oil pump is difficult to fix on the hammer body, the firmness is poor, and it often falls off

[0048] like image 3 and Figure 4 As shown, the oil pool 207 is surrounded by the groove on the top of the steam-air hammer body 209 and the oil pool side plates 210 welded to both ends of the groove; the bottom of the oil pool 207 is provided with a through hole 206, and the through hole 206 communicates with the oil pool 207 The position of the through hole 206 corresponds to the positio...

Embodiment 2

[0055] In order to increase the reliability of the system, on the basis of the first embodiment, the lubricating device of the steam-air hammer further includes an oil storage chamber and a second valve 205 .

[0056] like Figure 5 As shown, the oil storage chamber and the second valve 205 are arranged sequentially between the first valve 203 and the filling port 201 , and the oil storage chamber is located between the first valve 203 and the second valve 205 .

[0057] Embodiment 2 In order to increase the reliability of the system, an oil storage chamber and a second valve are added on the basis of Embodiment 1, and the structure of other parts is the same as that of Embodiment 1.

[0058] A method for using a steam-air hammer lubricating device, applied to the lubricating device described in Embodiment 2, comprising the following steps:

[0059] 21) Close the intake valve on the steam-air hammer intake pipeline;

[0060] 22) Close the second valve, open the first valve, ...

Embodiment 3

[0064] The oil sump can also be a separate part.

[0065] like Image 6 and Figure 7 As shown, the upper part of the oil pool 207' is an oil collecting pan 2072 with a guide groove 2071 that can match the guide rail at the edge. The center of the oil collecting pan 2072 is provided with a hammer rod through hole 2073. There are through holes 2075 corresponding to the guide grooves 2071 one by one; the lower half of the oil pool 207 is a positioning protrusion 2074 matching the groove on the top surface of the hammer body 209 .

[0066] The oil pool 207 is installed in the groove on the top surface of the hammer body 209 through the positioning protrusion 2074, the guide groove 2074 fits with the guide rail, and the hammer shaft passes through the hammer shaft through hole in the center of the oil pool 207′.

[0067] Due to the large volume of the hammer body, it does not depend on processing, and the oil pool is designed as a separate part, which is easy to manufacture.

Abstract

The invention discloses a lubricating device of a steam-air hammer and a use method of the device. The lubricating device comprises an oil pool, a second valve, an oil storage chamber, a first valve and an oil filling bucket, wherein the oil pool is connected with a guide groove through a through hole; and the second valve, the oil storage chamber, the first valve and the oil filling bucket are sequentially connected with an air inlet pipeline of the steam-air hammer through an oil filling port. The use method of the lubricating device of the steam-air hammer comprises the following steps of: storing lubricating oil in the oil filling bucket; opening the first valve for feeding the lubricating oil into the oil storage chamber; and closing the first valve and opening the second valve for feeding the lubricating oil into the air inlet pipeline of the steam-air hammer through the oil filling port. Under the action of compressed air or steam, the lubricating oil is atomized and uniformly attached to the surface of parts in a cylinder, is converged into lubricating oil in the form of large liquid drops, enters the oil pool, and is conveyed to the guide groove through the through hole for lubricating a guide rail. Due to the adoption of the device and the use method provided by the invention, the parts in the steam-air hammer can be lubricated uniformly, and the service life of each part is prolonged.

Description

technical field [0001] The invention relates to the technical field of forging equipment, in particular to a lubricating device for a steam-air hammer and a method for using the device. Background technique [0002] Steam-air hammer is a kind of free forging machine, which uses steam or compressed air to push the piston, and drives the hammer body to move up and down through the piston rod. The steam-air hammer is flexible in operation and widely used in the production of small and medium-sized forgings. Good lubrication can ensure the normal operation of the steam-air hammer and prolong its service life. Poor lubrication will cause serious wear on the cylinder wall, valve sleeve, packing sleeve, hammer rod, guide rail and other parts. The steam-air open die forging hammer is generally lubricated by an oil pump automatic lubrication system. [0003] See attached figure 1 , The oil pump automatic lubrication system mainly includes: rocker 101, oil pump 102, connecting rod ...
