Abstract
The invention relates to the technical field of centralizer manufacturing, in particular to a centralizer hoop forming device. The centralizer hoop forming device is characterized in that the centralizer hoop forming device comprises an upper die and a lower die matched with the upper die, wherein the middle of the lower die is U-shaped, the upper die is fixed on an upper die base, the lower die is fixed on a lower die base, and limiting grooves matched with the two sides of a steel plate are formed in the two sides of the lower die. The centralizer hoop forming device is simple in structure. According to the centralizer hoop forming device, the limiting grooves matched with the steel plate are formed in the lower die, the steel plate exactly fits the lower die when placed on the lower die, then the upper die is started to achieve bend-forming of the steel plate, and therefore forming quality of products is greatly improved; due to the fact that an air ejector rod used for ejecting the steel plate is arranged in the lower die, the steel plate is ejected automatically instead of adhering to the lower die after the upper die is withdrawn.
Description
Technical field
The present invention relates to the manufacturing technology field of centralizer, relate in particular to a kind of centralizer hoop shaped device.
Background technology
At present, need to pass through punching, bending, volume circle, the several steps of moulding when making the hoop of centralizer, in prior art, shaping work mainly carries out on stamping machine, the steel plate of well cutting is delivered between the upper die and lower die of stamping machine, restarted stamping machine, first bending and molding is being carried out on a limit, mould of the prior art location is inaccurate, causes the bending and molding effect poor.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned technology, and a kind of centralizer hoop shaped device is provided, improve forming quality of products.
The present invention for achieving the above object, by the following technical solutions:
A kind of centralizer hoop shaped device, it is characterized in that: comprise patrix, with the counterdie that described patrix coordinates, described counterdie middle part takes the shape of the letter U, described patrix is fixed on upper bolster, described counterdie is fixed on die shoe, and the both sides of described counterdie are provided with the stopper slot that is complementary with the steel plate both sides.
Preferably, be provided with the pneumatic jack bar that ejects for the steel plate with after moulding bottom described counterdie.
The invention has the beneficial effects as follows: the present invention is simple in structure, to the stopper slot that be complementary with steel plate be set on counterdie, when being placed on counterdie, steel plate just with counterdie, coincide, with starting patrix, and then, with the steel plate bending moulding, greatly improved the Forming Quality of product, be used for owing to being provided with one in counterdie the pneumatic jack bar that steel plate is ejected, make after patrix is regained, steel plate meeting automatic spring, and can not be attached on counterdie.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the hoop structure schematic diagram after moulding in the present invention;
In figure: 1, patrix; 2, counterdie; 3, upper bolster; 4, die shoe; 5, stopper slot; 6, pneumatic jack bar; 7, steel plate.
The specific embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing and preferred embodiment.as shown in Figure 1, a kind of centralizer hoop shaped device, comprise patrix 1, the counterdie 2 that coordinates with described patrix, described counterdie middle part takes the shape of the letter U, the shape of patrix is just opposite with the shape of counterdie, patrix can be pressed in counterdie in use, described patrix is fixed on upper bolster 3, described counterdie is fixed on die shoe 4, the both sides of described counterdie are provided with the stopper slot 5 that is complementary with the steel plate both sides, stopper slot be shaped as half arc, when steel plate is placed on counterdie, the steel plate both sides just can be put in this stopper slot, for the hoop with after moulding takes out, described counterdie bottom is provided with the pneumatic jack bar 6 that ejects for the steel plate with after moulding.
The present invention is simple in structure, to the stopper slot that be complementary with steel plate be set on counterdie, when being placed on counterdie, steel plate just with counterdie, coincide, with starting patrix, and then, with the steel plate bending moulding, greatly improved the Forming Quality of product, be used for owing to being provided with one in counterdie the pneumatic jack bar that steel plate is ejected, make after patrix is regained, steel plate meeting automatic spring, and can not be attached on counterdie.
The above is only the preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
