Abstract
The present invention relates to a kind of Pneumatic knocking hammer, comprise end cap (1), pressing plate (2), permanent magnet (3), hammer body (4), jump bit (5), spring (6), also comprise dividing plate (7), described end cap (1) is bolted on hammer body (4), pressing plate (2) and dividing plate (7) are fixed on hammer body (4) simultaneously, described permanent magnet (3) embeds pressing plate (2) bottom, and is fixed by dividing plate (7).Compared with prior art, the present invention has to be made permanent magnet depart to embed fixing position, and increases the radiating effect of permanent magnet, avoids magnetic force Yin Wendu raise and decay, and the advantage such as increase the service life.
Description
Technical field
The present invention relates to one and knock hammer, particularly a kind of Pneumatic knocking hammer.
Background technology
Pneumatic knocking hammer utilizes compressed air that jump bit is knocked at pipeline or feed bin position, and the powder making attachment, bond or be blocked in this position receives and impacts and loosen.
The Pneumatic knocking hammer of custom as shown in Figure 1, be made up of end cap 1, pressing plate 2, permanent magnet 3, jump bit 5, spring 6 and hammer body 4, wherein end cap 1 is bolted on hammer body 4, jump bit 5 is arranged in hammer body 4, and spring 6 is enclosed within jump bit 5, and permanent magnet 3 is embedded in jump bit 5, and be placed in pressing plate 2 times, because jump bit 5 knocks work by certain frequency, the permanent magnet 3 be embedded in jump bit is very easy to detach jump bit, causes Pneumatic knocking hammer to lose efficacy.Again because permanent magnet magnetic force after temperature is more than 80 DEG C can weaken, thus affect beating effect.
Summary of the invention
Object of the present invention is exactly provide a kind of permanent magnet can not to be departed from embed fixing position to overcome defect that above-mentioned prior art exists, and increase the radiating effect of permanent magnet, magnetic force Yin Wendu is avoided to raise and decay, the Pneumatic knocking hammer increased the service life.
Object of the present invention can be achieved through the following technical solutions: a kind of Pneumatic knocking hammer, comprise end cap, pressing plate, permanent magnet, hammer body, jump bit, spring, it is characterized in that, also comprise dividing plate, described end cap is bolted on hammer body, be fixed on hammer body by pressing plate and dividing plate, described permanent magnet embeds pressing plate bottom, and is fixed by dividing plate simultaneously.
Described permanent magnet has through hole.
Described through hole is provided with one or more, and each through hole connects source of the gas, and compressed air is by through hole injecting gas, and pinch shock hammer departs from the absorption of permanent magnet, and Compress Spring carries out hammer action.
Described dividing plate is placed in below pressing plate, forms with pressing plate the cavity that can be held permanent magnet.
Be provided with the projection extended inward bottom described dividing plate, form diameter and be less than the hole of permanent magnet, projection in described cavity, and separates permanent magnet and the jump bit below it by spacing for permanent magnet.
Compared with prior art, the present invention is formed by pressing plate and dividing plate and makes permanent magnet can not depart from the position embedding and fix, simultaneously, permanent magnet has through hole, compressed air is made to arrive below dividing plate by the through hole on permanent magnet, play good effect by air-flow by the heat radiation of permanent magnet like this, avoid magnetic force Yin Wendu raise and decay, increase the service life.
Accompanying drawing explanation
Fig. 1 is the existing structural representation knocking hammer;
Fig. 2 is the structural representation that the present invention knocks hammer.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
