Described spring is disk spring, and the spring force of described disk spring is greater than the weight summation of travelling table and mould.
For the moving method of middle-size and small-size table hydraulic machine, its step is as follows:
First, the action of push cylinder piston rod, draw hook promotes travelling table makes it roll in the elongate slots of sill, and shift out on main frame to guide rail and carry out material loading, its position is controlled by the mechanical limit switch on guide rail;
Secondly, the complete push cylinder backhaul of material loading, under the driving of piston rod, draw hook promotion travelling table moves on sill, under the spring-force driven dual of spring, the lower plane of travelling table keeps certain gap with the upper plane of sill all the time, only have roller to be contact with bottom sill elongate slots, controlled by the mechanical limit switch on sill in the position of sill;
Finally, after moving to appropriate location, main frame slide block works, at the further pressurized of its pressure lower spring, Compress Spring will make the upper plane contact of the lower plane of travelling table and sill, so that larger pressure is delivered to sill, slide block backhaul after hours, travelling table returns to again the position leaving sill under the spring-force driven dual of spring.
beneficial effect
Elasticity lifting device for middle-size and small-size table hydraulic machine of the present invention, spring force is compared with prior art utilized to make travelling table rise in the process moved in and out and disengage face, to reduce frictional force, reaching travelling table conveniently can frequently move in and out the effect of loading and unloading part up and down He carrying out die change.Structure is simple, equipment cost is low, aims at middle-size and small-size table hydraulic machine and designs, reducing equipment cost and the production cost of middle-size and small-size table hydraulic machine.

Detailed description of the invention
For making to have a better understanding and awareness architectural feature of the present invention and effect of reaching, coordinating detailed description in order to preferred embodiment and accompanying drawing, being described as follows:
As shown in figures 1 and 3, a kind of elasticity lifting device for middle-size and small-size table hydraulic machine of the present invention, the guide rail 6 comprising sill 5 and be connected with sill 5, sill 5 is arranged in table hydraulic machine, and be installed on the below of table hydraulic machine main frame slide block 1, also comprise travelling table 7, assembly pulley 2 is equipped with in described travelling table 7 bottom, described assembly pulley 2 matches with guide rail 6, assembly pulley 2 plays slip effect, described assembly pulley 2 can have four or six, quantity is determined to coordinate different weight requirements according to the weight of travelling table and mould.Described travelling table 7 sidepiece is installed with push cylinder 4 by draw hook 3, and push cylinder 4 controls travelling table 7 and moves along the direction of guide rail 6.
As shown in Figure 2, the rolling wheel support 24 that described assembly pulley 2 comprises cushion block 21 and is installed in cushion block 21, the mode of installation is the installing hole being designed to step shape in cushion block 21, installs rolling wheel support 24 in installing hole.Described cushion block 21 is installed on gland 26, and described rolling wheel support 24 top is provided with spring 22, and rolling wheel support 24 is built with bearing 23, and bearing 23 bottom is provided with bearing pin 25, bearing pin 25 is set with roller 27.The elongate slots corresponding with roller 13 can also be provided with in rolling wheel support 24, better can reduce frictional force so in use.Described spring 22 is disk spring, and the spring force of disk spring 22 is the weight being greater than travelling table and mould when press does not work.
For a moving method for middle-size and small-size table hydraulic machine, its step is as follows:
First, the action of push cylinder 4 piston rod, draw hook 3 promotes travelling table 7 makes it roll in the elongate slots of sill 5, shift out on main frame to guide rail 6 and carry out material loading, its position is controlled by the mechanical limit switch on guide rail, now can carry out the operations such as the replacing of mould on travelling table 7.
Secondly, the backhaul of material loading complete push cylinder 4, under the driving of piston rod, draw hook 3 promotes travelling table 7 and moves on sill 5, under the spring-force driven dual of spring 22, the lower plane of travelling table 7 keeps certain gap with the upper plane of sill 5 all the time, roller 27 is only had to be contact with bottom sill 5 elongate slots, controlled by the mechanical limit switch on sill 5 in the position of sill 5, because arranging of spring 22 can make the lower plane of travelling table 7 keep certain gap with the upper plane of sill 5 all the time, therefore also this elasticity lifting device can not be damaged in the replacing carrying out mould of medium and small hydraulic press upper frequency.
Finally, after moving to appropriate location, main frame slide block 1 works, at its pressure lower spring 22 pressurized further, Compress Spring 22 will make the upper plane contact of the lower plane of travelling table 7 and sill 5, so that larger pressure is delivered to sill 5, and slide block backhaul after hours.Spring force due to disk spring is greater than the weight summation of travelling table 7 and mould, but under the pressure of work, by spring 22 by the lower plane of travelling table 7 and sill 5 firm contact, pressure concentrates on sill 5, thus ensure that the stability requirement of mould in hydraulic process.After having worked, travelling table 7 returns to again the position leaving sill 5 under the spring-force driven dual of spring 22, can be user-friendly for again the demand of more mold exchange.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; the just principle of the present invention described in above-described embodiment and description; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in claimed scope of the present invention.The protection domain of application claims is defined by appending claims and equivalent thereof.
