Description

A kind of continuous hot-press stove

Technical field

The present invention relates to powder metallurgy forming apparatus field, more particularly to a kind of push boat type continuous high-efficient hot pressing furnace.

Background technology

Traditional heat pressing process equipment has two kinds：The first is first to be put into single workpiece in special hot-press equipment, Pressurizeed after the temperature of workpiece is increased into setting value, open fire door after furnace temperature cooling and manually take out workpiece；It is for second Increase thermatron on press, single workpiece is heated rapidly to require the after-applied pressure of temperature.Wherein, the first heat The shortcomings that pressing technique is that the time of heating and cooling is very long, and efficiency is very low；The shortcomings that second of heat pressing process is workpiece heat When there is no an atmosphere protection, exposure easily oxidation, and inefficient in atmosphere.

The content of the invention

Present invention aims at provide a kind of to realize streamlined powder metallurgy continuous hot-press and tunnel with atmosphere protection Road stove, so as to solve the above problems.

To achieve the above object, the invention discloses a kind of continuous hot-press stove, including body of heater and press, set in the body of heater Be equipped with for loading boat by and be provided at both ends with the transfer passage of gate valve, positioned at the transfer passage in the body of heater Outside is provided with heating element heater, and the pressure head of the press is stretched into the body of heater, and passes through the pressure head in the loading boat Lower section when, the pressure head moves downward, and the material in the loading boat after heating is pressed.

Further, the both ends of the transfer passage include loading boat can be by, the interior heat abstractor for setting interlayer, institute Heat abstractor is stated between the gate valve and body of heater, and is provided with water inlet pipe and outlet pipe.

Further, in addition to charging pipeline and discharging transmission line, the charging pipeline are provided with for by described in The charging push cylinder that boat is pushed into the transfer passage is fed, the discharging transmission line is provided with for will lead to from the conveying The discharging push cylinder that road is pushed open.

Further, the gate valve includes valve body and the insertion plate door along the slide in the valve body, on the valve body Offer and chute rake be formed slopely by hole to described by hole, one end of the chute for what loading boat passed through, The insertion plate door is plugged in the chute, and the insertion plate door is driven and to described by being fixed in drive cylinder above valve body During chute rake end movement, the insertion plate door progressively compresses passes through hole described in closing.

Further, the valve body includes being provided with the door-plate by hole, and the door-plate both sides pass through affixed side For plate shape into slot structure, the side plate, which is located at, removable in slot structure is provided with a plate, the through hole opened up on the plate and institute The inwall for stating side plate forms the chute, and the both sides of the insertion plate door are connected with lead, and the lead is plugged in described In chute and along the slide.

Further, the both sides of the insertion plate door are also connected with wearing plate, and the wearing plate is arranged on insertion plate door and plate Between, and positioned at the top of the lead.

Further, the top of the insertion plate door is relative is connected with two supporting plates, is relatively set with the supporting plate Waist-shaped hole, the end of the drive cylinder are connected with rotating shaft, and the rotating shaft runs through two waist-shaped holes, and the waist-shaped hole tilts Set, and pass through hole further from described relative to the other end close to one end of the slot structure bottom surface.

Compared with prior art, the advantage of the invention is that：

1st, first, the present invention uses tunnel-type hearth structure, passes through burner hearth into queue equipped with the loading boat for treating die pressing product（It is i.e. defeated Send passage）Heating, has reached requirement temperature when reaching press position pressurization, and then realizing quickly to suppress, and transfer passage Be provided at both ends with gate valve, so as to ensure product whole process non-oxidation under atmosphere protection, meanwhile, by full-automatic feeding-discharging side Formula, time and artificial is saved, while reduce energy consumption, drastically increase product quality and production efficiency.

2nd, secondly, door valve structure of the invention is compact, the space very little taken when opening and closing, wherein, Under the driving of cylinder, during insertion plate door moves downward, when insertion plate door is to chute rake end movement, it can close and pass through Hole, while be gradually pressed on door-plate, due to the inclined plane of chute rake, the power that cylinder pushes can produce a bigger power Insertion plate door is acted on door-plate, that is, the effect of the transfer and amplification of a power is played, so as to preferably prevent tunnel stove Leakage, ensure the atmosphere protection environment in transfer passage, while also reduce thermal loss.

Below with reference to accompanying drawings, the present invention is further detailed explanation.
