The specific embodiment
The structural representation of a kind of embodiment of the utility model as shown in Figure 1; A kind of extruder fast demoulding device; Comprise being located at and be used on the frame 1 mould bases 2 of extruding assembly being installed and being located at the demoulding assembly on the frame; Said extruding assembly is positioned on the extrusion position a of corresponding blank to be extruded; Said extruding assembly comprises extrusion die 3 and the die sleeve 4 that extrusion die is installed, and is provided with between said mould bases and the frame to make the mould bases action will push assembly to move to the movement structure that the demoulding position b of corresponding demoulding assembly carries out the demoulding from extrusion position.Said demoulding assembly comprises the driver that is fixed on the frame and by driver drives is reciprocating extrusion die ejected the backform bar of die sleeve, and with the spacing position limiting structure in mould bases of die sleeve.Said driver is a double-head cylinder 5; Said backform bar is the preceding plunger 51 of double-head cylinder; Said position limiting structure comprises the back-plunger 52 of double-head cylinder and is slidingly connected at the position-limited rack 6 on the frame; The rear end of position-limited rack is fixedly connected with back-plunger, and the front end of position-limited rack is provided with and props up die sleeve prevents that die sleeve from coming off from mould bases when preceding plunger ejects extrusion die button pawl 61.
In the present embodiment; Said position-limited rack comprises at least two extension rods 62; The rear end of said extension rod is provided with connecting rod 63 and links to each other, and connecting rod is fixed on the back-plunger, and extension rod is installed in the frame and frame front and back slippage relatively; The front end of extension rod stretches out mould bases, and said button pawl is located at the front end of extension rod.
In addition; Said movement structure comprises power set and the slide rail 11 that is located on the frame; Mould bases drives the slippage between extrusion position and demoulding position of lower edge slide rail at power set; Said slide rail is horizontally disposed with and the throughput direction of vertical blank to be extruded, also is provided with the positioner of when the extruding assembly is in extrusion position, mould bases being had good positioning on the frame.In order to make structure compact more; Said power set and positioner are the single head hydraulic cylinder 12 that level is installed; The plunger of single head hydraulic cylinder is fixedly connected and promotes mould bases along the slide rail slippage with mould bases, the stroke of single head hydraulic cylinder is not less than the horizontal range between extrusion position and the demoulding position.Certainly consider the stability of mould bases, positioner can also be set separately, the device of handled easilies such as similar lathe self-locking frame.
Shown in Fig. 2 to 5, the operation principle of the utility model is following, when extrusion die need be changed, stops extruder; The release mould bases starts the single head hydraulic cylinder, pressurization; Mould bases is pushed to demoulding position from extrusion position, and the single head hydraulic cylinder keep-ups pressure then, and mould bases is positioned at demoulding position; Then start double-head cylinder, pressurization, the preceding plunger of double-head cylinder and back-plunger move forward and backward relative to double-head cylinder respectively under the effect of hydraulic coupling; Back-plunger drives position-limited rack and moves backward, makes the button pawl prop up die sleeve, and preceding plunger continues to move forward; Be against at last on the extrusion die to be changed extrusion die to be changed is released die sleeve; Double-head cylinder moves back oil decompression then, and back-plunger and preceding plunger are all withdrawn in the double-head cylinder, and the extrusion die that the workman will newly change is packed in the die sleeve; Last single head hydraulic cylinder moves back the oil decompression, drags mould bases and gets back to extrusion position from demoulding position, accomplishes whole demoulding die change process, and after mould bases was locked again, extruder can be proceeded extruding work.
Following table is compared the present invention with traditional stripping means, further specify the superiority of the utility model.
Table 1: with 2000T extruder extrusion brass C2700 φ 49x2.5 is example, whenever at a distance from one hour die change once
From above table, can find out, mode of the present invention not only the time save tens times, and improved 50% service life.
The utility model one can guarantee fast demoulding die change in extruding, and whole process was accomplished in 30 seconds, can effectively promote production capacity and make rationalization of production, can reduce mould replacing time, meets a small amount of various production order, reduces stock and reduces labor cost etc.; Two can improve the service life of extrusion die greatly, and when the extrusion brass red copper, the ingot casting temperature range is at 700 ℃～880 ℃, and when the extruding copper-nickel alloy; The ingot casting temperature range is at 900 ℃～1100 ℃, and in extrusion process, extrusion die directly contacts with ingot casting; Cause extrusion die operation at high temperature for a long time, produce heat fatigue, cause extrusion die easy abrasion even cracking; This cover fast demoulding device, extrusion die can in time be rotated operation, can avoid the heat fatigue that produces under the long-time high-temperature operation of extrusion die; Thereby is provided the service life of extrusion die greatly, improves the extrusion die service property (quality), also improved the lumber recovery of tubing.Three also improve processing safety greatly, compare with the stripping means that manual work in the existing extruding is beaten, and this device stripping operation safety, convenient and reliable, improved the production management modernization, improve the environment of plant, the enterprises comprehensive competitiveness is provided.
Except that above-mentioned preferred embodiment; The utility model also has other embodiment; Those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from the spirit of the utility model, all should belong to the defined scope of the utility model accompanying claims.
