Description
Technical field
Relate to fork truck mould applications when the utility model relates to, be specifically related to a kind of semi-surrounding pallet fork mould.
Background technology
Pallet fork is the important component part on fork truck or lifting engineering truck, has a wide range of applications in the carrying transport of material.According to the difference of pallet fork bearing capacity; the part shape of pallet fork 10 is also different; the structure of usual pallet fork needs the bearing capacity ensureing pallet fork; alleviate the weight of pallet fork as much as possible simultaneously; the crosssection shape design of pallet fork is become top bending for this reason and there is the openning type of opening; the pallet fork structure of this shape, often by plate in advance by two ends bending, last moulded section.Due to the particularity of the pallet fork structure of this openning type, need to adopt mould to complete last moulded section.
The part directly playing shaping effect in mould is generally wedge structure, as shown in Figure 1, the wedge structure of this mould comprises wedge punch 1, this wedge punch 1 has wedge portion 2, wedge portion 2 has the through hole 3 that some horizontal directions are arranged, be provided with bearing pin 4 in through hole 3, the diameter of this bearing pin 4 is less than the aperture of through hole 3; The both sides in this wedge portion 2 are provided with the forming convax mould 5 slided of fitting with this wedge portion 2, forming convax mould 5 and bearing pin 4 are slidably connected, forming convax mould 5 is provided with accepting hole 6 away from the one end in wedge portion 2, spring 7 is provided with in this accepting hole 6, the two ends of bearing pin 4 are provided with limiting section 41, one end of spring 7 and limiting section 41 against, the other end of spring 7 and forming convax mould 5 against.The principle of this wedge structure is: during pressing mold, and wedge punch 1 moves upward, and then makes forming convax mould 5 to two lateral movements, thus completes forming action; During the demoulding, this wedge punch 1 moves downward, and then forming convax mould 5 is resetted to intermediary movements under the effect of spring 7, thus completes the demoulding easily.As shown in Figure 2, in prior art, because this wedge punch 1 is generally all-in-one-piece elongate configuration, and forming convax mould 5 to be fitted this wedge punch 1 along the length bearing of trend of this wedge punch 1 comprehensively, the volume and weight of this monoblock type wedge structure is all larger, be unfavorable for processing and manufacture, and in batch production process, the pressing mold action of continuous repetition is not easy accurately to control dynamics, thus the impulsive force transmitted when causing pressing mold is comparatively large, easily exceeds the carrying scope of mould, causes bearing pin to ftracture, thus causing the damage of mould, production efficiency is lower.
Utility model content
The purpose of this utility model is to provide a kind of semi-surrounding pallet fork mould, and this mould can reduce the impulsive force of forming convax mould to bearing pin, improves the mold use life-span, enhances productivity.
For achieving the above object, the utility model have employed following technical scheme: comprise wedge punch, the bottom of this wedge punch is provided with wedge portion, described wedge portion is provided with the through hole that multiple horizontal direction is arranged, bearing pin is provided with in described through hole, the diameter of this bearing pin is less than the aperture of through hole, the both sides in described wedge portion are respectively equipped with the forming convax mould slided of fitting with this wedge portion, described forming convax mould is connected with pin slide, forming convax mould is provided with accepting hole away from the one end in wedge portion, spring is provided with in accepting hole, the two ends of bearing pin are provided with limiting section, one end and the limiting section support of spring are leaned on, the other end of spring and forming convax mould against, described wedge punch is provided with the damper that vertical direction is arranged.
The upper surface of described wedge punch is provided with the groove for installing damper.
Described interval, wedge portion is arranged in the bottom of wedge punch, is provided with spacing insert between adjacent two wedge portions.
The inner side of described forming convax mould is provided with the groove matched with spacing insert, and described spacing insert is arranged in groove.
As shown from the above technical solution, the utility model by arranging damper on wedge punch, when the pressure of hydraulic press is delivered to bearing pin by wedge punch, damper absorbs sections transverse and acts on impulsive force on bearing pin, but wedge partial solution to forming terrace die promotes the plastic force of workpiece does not reduce, the setting of damper reduces the impulsive force to bearing pin, thus improves force structure and the service life of bearing pin.

Fig. 2 is the structural representation of wedge punch in the utility model background technology;
Fig. 3 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
A kind of semi-surrounding pallet fork mould as shown in Figure 3, comprise wedge punch 100, the bottom of this wedge punch 100 is provided with wedge portion 101, wedge portion 101 is provided with the through hole 102 that multiple horizontal direction is arranged, bearing pin 103 is provided with in through hole 102, the diameter of this bearing pin 103 is less than the aperture of through hole 102, the both sides in wedge portion 101 are respectively equipped with the forming convax mould 200 slided of fitting with this wedge portion 101, forming convax mould 200 and bearing pin 103 are slidably connected, forming convax mould 200 is provided with accepting hole 104 away from the one end in wedge portion 101, spring 105 is provided with in accepting hole 104, the two ends of bearing pin 103 are provided with limiting section 106, one end of spring 105 and limiting section 106 against, the other end of spring 105 and forming convax mould 200 against, wedge punch 100 is provided with the damper 300 that vertical direction is arranged.In Die & Mould Forming Process, forming pressure is delivered to bearing pin by wedge punch, adjoint wedge punch is to the impulsive force of bearing pin mid portion simultaneously, damper the impulsive force that can absorb wedge convex portions is set, thus the impact reduced bearing pin, reach and extend working time, the effect of increasing work efficiency.
Further, the upper surface of wedge punch 100 is provided with the groove 107 for installing damper 300.Namely the screw thread of damper 300 side is utilized, on wedge punch, fluting is installed, when hydraulic press pressure is delivered to bearing pin by wedge punch, damper absorbs sections transverse and acts on impulsive force on bearing pin, but wedge partial solution to forming terrace die 200 promotes the plastic force of workpiece does not reduce, thus improve the force structure of bearing pin, improve the service life of bearing pin.
Further, interval, wedge portion 101 is arranged in the bottom of wedge punch 100, is provided with spacing insert between adjacent two wedge portions 101.Further, the inner side of forming convax mould 200 is provided with the groove matched with spacing insert, and spacing insert is arranged in groove.The wedge portion of wedge punch adopts section gap to arrange and is provided with the structure of spacing insert between two between wedge portion, the weight of wedge punch can be subtracted, thus be lowered into the impulsive force that mould produces when pressing mold, avoid the generation of bearing pin cracking phenomena, improve production efficiency.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
