Detailed Description

The following describes a heat-preservation hot press according to an embodiment of the present invention in detail with reference to the accompanying drawings.

Examples

Referring to fig. 1-3, the heat preservation hot press of this embodiment includes a frame, a control box 15, a lower die, an upper die, a telescopic cylinder 8 and a hydraulic cylinder 10, the upper die and the lower die are installed on the frame vertically and oppositely, the upper die includes a lifting plate 16, an upper die heating plate 5 and an upper die plate 13 which are connected in sequence, the top end of the lifting plate 16 is connected with the hydraulic cylinder 10, a guide pillar 11 is arranged on the bottom surface of the upper die plate 13, the lower die includes a lower die heating plate 6, a workbench 9 and a bottom plate 7, the lower die heating plate 6 is fixed on the lower side of the workbench 9, the bottom plate 7 is arranged on the upper side of the workbench 9, a mounting hole matched with the guide pillar 11 is arranged on the bottom plate 7, and the rear side of the bottom plate 7 is connected with the telescopic cylinder 8.

The inner diameter of the mounting hole is larger than the diameter of the guide post 11.

Frame bottom is equipped with frame box 17, frame box front portion is equipped with operation panel 18, workstation 9 sets up on frame box 17, operation panel 18 and two mesa parallel and level of workstation 9, under telescopic cylinder 8's effect, bottom plate 7 can be switched on operation panel 18 and workstation 9 by the back-and-forth movement, frame upper portion is equipped with baffle 19, it is equipped with guide support post 20 to lie in baffle 19 inboard on the frame box 17, guide support post 20 top is fixed with roof 21, hydraulic cylinder 10 installs on roof 21.

Guide support post 20 is equipped with 4, installs respectively in the four corners department of frame box 17, lifter plate 16 is the rectangular plate, and lifter plate 16's four corners department is equipped with the sleeve, the sleeve suit is outside guide support post 20, and under hydraulic cylinder 10's effect, lifter plate 16 can drive and go up mould hot plate 5 and cope match-plate pattern 13 and reciprocate perpendicularly along guide support post 20.

The control box 15 is arranged on one side of the rack, and an upper die temperature controller 2, a lower die temperature controller 3 and a parameter display screen 4 are arranged on the control box 15.

The electronic ruler 12 is mounted on the baffle plate 19.

When the spring forming machine is used for forming, firstly, the upper die temperature controller 2 and the lower die temperature controller 3 are adjusted to the temperature required by the spring, so that the upper die heating plate 5 and the lower die heating plate 6 are heated;

the time for the spring to keep warm is set through the parameter display screen 4;

the spring is placed in the bottom plate 7, and the telescopic cylinder 8 moves the bottom plate 7 loaded with the spring 1 to the workbench 9 after receiving a signal;

after receiving the signal, the lifting hydraulic cylinder 10 drives the upper die heating plate 5 and the upper die plate 13 to move downwards, and the guide pillar 11 penetrates through the inner diameter of the spring 1 to complete the pressing action;

the temperatures of the upper and lower die heating plates 5 and 6 are transferred to the upper die plate 13 and the base plate 7, and then to the springs, using a heat transfer principle.

When the springs are placed, the springs are placed on the operating table in the front of the rack box body, and potential safety hazards caused by descending of the upper die are avoided.

The heating principle is as follows: the heating pipe is embedded into the heating plates of the upper die and the lower die, the heating pipe is a heating pipe in the prior art, the heating pipe generates heat to transfer the temperature to the bottom plate and the guide pillar, the upper die plate and the bottom plate are closed after the spring is forced to press, the temperature is transferred to the spring steel wire, the heating temperature of the spring is adjusted by controlling the heat preservation time, the spring steel wire can be completely heated after 20S heat preservation, when the temperature reaches 120 ℃, the elastic modulus of the steel wire is reduced by about 8%, the spring generates permanent deformation, the upper die and the lower die are separated, the lower bottom plate returns, the spring automatically drops, and the size of the spring is small when the spring is used in a high-temperature environment.
