Problems solved by technology

[0002] Casting coils for dry transformation is a necessary process for the production of dry transformations. Similarly, drafting after casting the coils is also a necessary process. For this process, there are many implementation schemes, and the most primitive one is to use impact hammering for drafting. There are also cases where the casting coil is fixed and the mold is pulled out by driving and hoisting. These operations are laborious and time-consuming and cannot guarantee the smooth completion of the pulling process.
There are also oil cylinders arranged on the upper part of the casting coil, and the mold is pressed out from the upper part to realize the drafting, but such a hydraulic drafting device not only occupies the operating space, but also affects the lifting and placement of the casting coil

Embodiment Construction

[0010] Such as figure 1 A hydraulic drawing device for dry variable casting coils is shown, including a support 7, a coil mold 5 and an oil cylinder 6, the oil cylinder 6 is located underground; the support 7 is provided with a pressing block 3, and the pressing block 3 is movable; the pressing block 3 is movable through the screw rod 2; the bottom of the bracket 7 is also provided with a slide groove 1.

[0011] According to the diameter of the compressible coil 4, the lateral position of the support 7 is adjusted through the T-shaped chute 1 of the lower base plate, and then the axial position of the briquetting block 3 is adjusted through the screw 2 according to the height of the compressible coil 4, and then the poured The compressible coil 4 is placed therein, and the pressing block 3 is firmly pressed on the upper end of the compressible coil, and finally the oil pressure control system is started to lift the piston of the oil cylinder 6 to realize the drafting.

Abstract

The invention relates to an oil pressure drafting device of a dry-variable casting coil, comprising a bracket, a coil mould, an oil cylinder and an oil pressure control system. The oil cylinder is located under the ground; the bracket is provided with a movable press block which is moved through a screw; and a chute is further arranged at the bottom of the bracket. The invention overcomes the defect that the oil cylinder arranged above the ground occupies the operation space by setting the oil cylinder underground, ensures that the piston stroke of the oil cylinder can be controlled by operating a button of the oil pressure control system so as to draft the casting coil, overcomes the defects that more labour and time are consumed by using a crane dry drafting mould and the drafting operation can not be implemented smoothly, simplifies the drafting process and improves the drafting efficiency.

technical field [0001] The invention relates to a coil hydraulic drafting device, in particular to a dry-variable casting coil hydraulic drafting device. Background technique [0002] Casting coils for dry transformation is a necessary process for the production of dry transformations. Similarly, drafting after casting the coils is also a necessary process. For this process, there are many implementation schemes, and the most primitive one is to use impact hammering for drafting. There are also cases where the casting coil is fixed and the mold is pulled out by driving and hoisting. These operations are laborious and time-consuming and cannot guarantee the smooth completion of the pulling process. There is also an oil cylinder arranged on the upper part of the casting coil, and the mold is pressed out from the upper part to realize the drafting. However, such a hydraulic drawing device not only occupies the operating space, but also affects the lifting and placement of the c...
