Abstract
The utility model relates to a trestle for reaming a mandrel in free forging, comprising a pair of supporting members for supporting the mandrel and a base, wherein arc grooves for placing the mandrel are arranged at the upper ends of the supporting members; grooves capable of being mounted and matched with the supporting members are arranged at two ends of the base; and two supporting members are respectively arranged in the grooves at two ends of the base, are connected with the base through two pin rolls and can freely rotate around the pin rolls. The trestle for reaming the mandrel can be detached, has favorable fixity and convenient replacement, reduces the labor intensity and improves the production efficiency. In addition, the utility model not only can be used as the trestle, but also the t base after the two supporting members are detached can be used as an anvil block, so that the cost is saved.
Description
Technical field
The utility model relates to the instrument that uses in a kind of flat-die forging technology, specifically is mandrel reaming saddle support in a kind of flat-die forging.
Background technology
In FMT, reduce the hollow blank wall thickness and the forging process that increases external diameter in it is called reaming, the method for reaming has two kinds of punching press reaming and mandrel reamings.The mandrel reaming is that mandrel is inserted in the disk blank with holes, and the mandrel two ends are placed on the saddle support, and by disk outer radius with holes being exerted pressure and the continuous running of mandrel realizes reaming, therefore uses very extensive.In use, general saddle support is whole, and own wt is heavy, replacing bothers, the workman operates, and labour intensity is big, and the not stationarity of saddle support on the anvil piece brought a lot of inconvenience and produced potential safety hazard to operation.
The utility model content
The technical problems to be solved in the utility model is: in order to solve problems such as general saddle support own wt is heavy, replacing bothers, operation labour intensity is big, provide a kind of mandrel reaming saddle support.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of mandrel reaming saddle support, support member and a base of comprising a pair of support mandrel, the support member upper end has the arc groove of placing mandrel, the base two ends have and can the groove that cooperate be installed with support member, two support members are installed in respectively in the groove at base two ends, two support members are connected by two bearing pins with base, and support member can freely rotate around bearing pin.
The beneficial effects of the utility model are: this mandrel reaming is detachable with saddle support, and stationarity is good, and it is convenient to change, and has reduced labour intensity, has improved production efficiency; Not only can work as saddle support and use, pull down two support members after, remaining base can also work as the use of anvil piece, provides cost savings.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
The explosive view of Fig. 2 Fig. 1;
Fig. 3 is to use state diagram.
1. support members among the figure, 11. arc grooves, 2. base, 21. grooves, 3. bearing pin, 4. mandrel, 5. disk blank.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, 2, a kind of mandrel reaming saddle support, support member 1 and a base 2 of comprising a pair of support mandrel, support member 1 upper end has the arc groove 11 of placing mandrel, base 2 two ends have and can the groove 21 that cooperate be installed with support member 1, two support members 1 are installed in respectively in the groove 21 at base 2 two ends, and two support members 1 are connected by two bearing pins 3 with base 2, and support member 1 can freely rotate around bearing pin 3.
As shown in Figure 3, during use, mandrel 4 is inserted in the disk blank 5 with holes, then mandrel 4 is placed on the mandrel reaming with on the saddle support, by disk blank 5 external diameters being exerted pressure and the continuous rotation of mandrel 4 realizes reaming; When not using this mandrel reaming to use saddle support, two support members 1 can be removed, remaining base 2 can be used as the anvil piece and uses.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
