Technical field

The utility model discloses a kind of hull and pulp removing machine structure, the hull and pulp removing machine structure when being specifically related to a kind of stamping machine back-pressure bending.

Background technology

After with stamping machine material being carried out reverse punching press, the material after the punching press forms crimping or elbow, and material is hung on the mould molding piece, influences the blanking of material, thereby has reduced the production efficiency of stamping machine and limited its automaticity.Thereby, need a kind of mechanism of taking off the material action that in punching press bending process, just can finish synchronously of exploitation badly, enhance productivity.

The patent No. is " CN200620056491.2 ", patent name is " a kind of diel stripper ", disclose that " the expensive low diel bending and molding stripper of a kind of precision, it mainly comprises mould, centering block, Bending punch, fixed block and ejector member.But wherein said mould comprises on the folding, lower bolster, and its cope match-plate pattern comprises stripper plate and baffle plate again, and described fixed block promptly is arranged on the stripper plate, another centering block then nationality is articulated on the fixed block by steady pin, this fixed block also is provided with the pendulum angle that a protruding layer is used to limit centering block, described Bending punch then be provided with lower bolster on, carry out bending and molding in order to match with centering block, included patrix knock pin and the counterdie knock pin of its ejector member is arranged at baffle plate and lower bolster respectively in addition, in order to auxiliary centering block swing and location." this patent its to adopt be the mode bending of malleation, mainly adopt centering block swing certain angle to realize taking off material, this structural stability poor synchronization.

The utility model content

At above-mentioned defective, the utility model purpose 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 adopted in the utility model is:

A kind of back-pressure hull and pulp removing machine structure of the present utility model, 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 kind of preferred embodiment of the present utility model, 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 kind of preferred embodiment of the present utility model, the described inclined-plane that takes off piece material floating life is stepped.

In a kind of preferred embodiment of the present utility model, 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 kind of preferred embodiment of the present utility model, described back-pressure hull and pulp removing machine constitutes using, and mirror image is installed.

The utility model 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 utility model is rational in infrastructure, and stability is high.

The specific embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby protection domain of the present utility model is made more explicit defining so that advantage of the present utility model and feature 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 utility model 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 utility model, 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 embodiment of the present utility model, 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 utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
