Summary of the invention
At above-mentioned defective, the object of the invention provides a kind of hull and pulp removing machine structure that takes off the material action of just finishing synchronously in punching press bending process.
For achieving the above object, the technical solution used in the present invention is:
A kind of back-pressure hull and pulp removing machine structure of the present invention, comprise forming blocks, the compacted under piece takes off material piece floating life, guide fixed block, vertical push rod and back-moving spring, there is a moulded head the described material piece floating life upper end of taking off, cooperates with described upward forming blocks, compacted under piece material is carried out inverse bending, and its lower end includes an inclined-plane and contacts with the guiding surface of described guide fixed block, the planar section of its lower end contacts with the upper end of vertical push rod, and there is a back-moving spring lower end of described vertical push rod.
In a preferred embodiment of the present invention, described guide fixed block has a gathering sill, and the described lower end of taking off material piece floating life has a slide block to be installed in the described gathering sill.
In a preferred embodiment of the present invention, the described inclined-plane that takes off piece material floating life is stepped.
In a preferred embodiment of the present invention, the gathering sill of described guide fixed block and guiding surface and to take off the angle of inclination, inclined-plane of material piece floating life consistent.
In a preferred embodiment of the present invention, described back-pressure hull and pulp removing machine constitutes using, and mirror image is installed.
The present invention compared with prior art has the following advantages: cooperate by simple frame for movement, material piece floating life that takes off of band moulded head is travelled forward downwards when punching press, upwards move backward when dividing mould and reset, thereby make the material success of bending forming take off material synchronously, improved production efficiency, the present invention is rational in infrastructure, and stability is high.

The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby protection scope of the present invention is made more explicit defining so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that.
As Fig. 1 in conjunction with Fig. 5, shown in Figure 6, present embodiment comprises forming blocks 1, material 2, compacted under piece 3 from top to bottom, takes off material piece 4 floating life, guide fixed block 5, vertical push rod 6, back-moving spring 7, described taking off expects that front end has a moulded head 41 on the piece 4 floating life, there are one section inclined-plane 42, one section plane 43 and slide block 44 in the lower end, there is a guiding surface 51 described guide fixed block 5 upper ends, also have a gathering sill 52, described gathering sill 52 is consistent with the angle of inclination of guiding surface 51.
Position that each member is concrete and annexation are: the moulded head 41 of going up forming blocks 1, compacted under piece 2 and taking off front end on the material piece 4 floating life cooperates material 2 back-pressure bending formings, described 42 sections guiding surfaces 51 with guiding piece 5 floating life in inclined-plane that take off material piece 4 lower ends floating life contact, both angles of inclination are consistent, described 43 sections upper ends with vertical push rod 6, plane of taking off material piece 4 lower ends floating life contact, and the lower end of vertical push rod 6 is equipped with back-moving spring 7.
In conjunction with Fig. 2, shown in Figure 3, describe the course of work of the present invention down in detail:
A, punch forming, to position shown in Figure 2: the punching press effect is gone up forming blocks 1 down and is pressed down material piece floating life 4 that takes off that is subjected to the spring force come-up that coexists and form pressure-plate-forces, take off material floating life piece 4 under the pressure of last forming blocks 1 along guide fixed block 5 according to the angle slippage of being scheduled to forward downwards, the described moulded head 41 that takes off material piece 4 floating life arrives the operating position, with compacted under piece 2, upward forming blocks 1 formation bending action, promptly negative shape is finished;
B, take off the material reset, to position shown in Figure 3: forming blocks 1 retreats under the driving of punching press backhaul, take off the driving float downward of material piece 4 floating life at back-moving spring 7 spring forces of vertical push rod 6, driving material has taken off, taking off material piece 4 floating life upwards resets under the guiding of the guiding surface 51 of guide fixed block 5 backward, and material just upwards resets, thereby completes successfully and take off material, promptly finishes a circulation.
As shown in Figure 4, when the material require both sides all bend, but mirror image is installed two structures of the present invention, so only needs a circulation just can finish two Edge Bends simultaneously and takes off material process.
As Fig. 5, shown in Figure 6, in the preferred embodiments of the present invention, take off inclined-plane 42 structures of piece 4 material floating life, and the guiding surface 51 of the guide fixed block 5 that matches is all made stepped, such respective outer side edges and is got up rationally stable more.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
