本考案はダイ交換を迅速に行なわせることのできる回転
ホイール式連続金属押出装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotating wheel type continuous metal extrusion device that allows quick die changes.

ト３に設けたダイ穴から製品６を押出すようになってい
る。As shown in FIG. 1, a conventionally known rotating wheel type continuous metal extrusion device has a circumferential groove 2 of a rotating wheel 1;
For example, a rod-shaped metal material 5 is continuously fed into an extrusion chamber composed of a die segment 3 and an abutment 4 that cover a part of the metal material using the frictional force of the circumferential groove of the foil, and is then fed through a die hole provided in the die segment 3. The product 6 is extruded.

ト３及びアバツトメント４を保持するシュー７を開放し
ようとしても材料の押し残りがダイ近傍に残存しており
、シュー７とホイール１とに強力な離反力をもっている
ため、シュー７の開放は極めて困難である。In such an extrusion device, after extruding a certain product, for example, even if an attempt is made to open the shoe 7 that holds the die segment 3 and the abutment 4 in order to replace the die, unpressed material may remain in the vicinity of the die. Since the shoe 7 and the wheel 1 have a strong repelling force, it is extremely difficult to open the shoe 7.

の如く回転させて開放するのであるが、ピン１０を抜く
のが難かしく、これまではシュー７をハンマーリングし
ながら徐々に抜いているのが現状である。As shown in FIG. 2, the shoe release means of the conventional device is to pull out the pin 10 connecting the shoe 7 and the link 9 whose one end is supported by the pin 8 using a screw jack or hydraulic jack, and to release the support pin 11 of the shoe 7. It is opened by rotating the shaft center as shown by the chain line in the figure, but it is difficult to remove the pin 10, and the current situation is to gradually remove the shoe 7 while hammering it.

迅速に行なわせることにある。The purpose of this invention is to improve upon the current state of the art and to allow the shoe holding the die to be opened easily and quickly when exchanging the die.
以下、その実施例を第３図及び第４図にもとづいて説明
する。The embodiment will be described below based on FIGS. 3 and 4.

シュー７に作用する反力を受持たせるようにしたもので
ある。Reference numeral 12 denotes a member provided at the joint between the shoe 7 and the link 9 so as to be held by the shoe 7 and to hold the pin 10. A member 12 is held by the bolt 16 so as to fit into the hole 15 formed in the shoe 7. It has a two-sided structure that can be inserted and removed freely, and the upper part in the figure has an inclined sliding surface 12a formed near the friction angle,
A wedge mechanism consisting of a wedge 13 having a sliding surface mating therewith is provided, and the reaction force acting on the shoe 7 is borne by this wedge mechanism.

ても同効である。In this invention, the mechanism for releasing the reaction force between the wheel and the shoe is provided at the connecting part between the shoe 7 and the link 9. The same effect can be achieved even if the wedge mechanism according to the present invention is provided in the support section.
この考案は、以上詳述したような構造と作用をもってい
るので、考案所期の目的を確実に達成することができ、
省力化、生産性の向上等に極めて有効である。Since this invention has the structure and function described in detail above, it is possible to reliably achieve the purpose for which it was invented.
It is extremely effective in saving labor and improving productivity.
