Abstract
The utility model relates to dismounting of pins of a combination die, and specifically relates to a pin puller used for dismounting positioning pins. The pin puller mainly comprises a bracing frame, a nut, a pin pulling shaft, a screw and the like. The pin pulling shaft is a threaded screw rod, and one end of the pin pulling shaft is equipped with a clamping port. The bracing frame is formed by a supporting plate and two pillars fixedly perpendicular to the supporting plate. The bracing frame is provided with a through hole that allows the screw rod of the pin pulling shaft to pass through and is positioned between the two pillars. The pin pulling shaft passes through the through hole and is equipped with the nut that can abut against the bracing frame. The cap of the screw is placed in an open groove of the clamping port 7 of the pin pulling shaft 2. The pin puller of the utility model helps to solve problems that a conventional pin puller for dismounting positioning pins of a combination die is time-consuming and labor-consuming, is not easy in pin dismounting, causes quite large impact force, has insufficient space, etc. The pin puller which is simple and reasonable in structure, exhibits good usage effects and is labor-saving and time-saving is suitable for dismounting positioning pins in various combination dies.
Description
Technical field
The utility model relates to the dismounting of assembling die shop bolt, specifically a kind of plain type pin removal of implementing shop bolt dismounting.
Background technology
Field of compound material mould therefor is metal die substantially now, and many large scale structures or complex-shaped structure are all to adopt assembling die, and assembling die generally all couples together by trip bolt and shop bolt.Composite product can not contact oily substance in process of production, so can not scribble lubricated class material in using assembling die process; And composite resin in solidifying temperature-rise period can flow in the screw and pin hole of assembling die, will cause like this knockout course very difficult.
The dismounting of shop bolt generally adopts servicing unit to dismantle, and is generally impacting type pin removal, is fixed with the rod member that impact block and end can be threaded with the screw of pulling pin in axial end on it.During use, Rod end is threaded with screw on shop bolt end face fixing, outwards knocks impact block, utilize the outside impact of impact block that shop bolt is extracted, and need certain shock space.The needed impact of this dismounting mode is larger, is firmly that people's work is directly given power, and has certain shock space, needs multiple impact, shop bolt could be extracted, and very wastes time and energy.This dismounting mode is totally unfavorable for composite, clash into and can produce to composite product the defects such as hole, layering, and the space in assembling die seldom, there is no enough shock spaces, and causing cannot the demoulding.Present fluid pressure type pin removal support body is larger, and pin diameter all exists
above, weight is generally 80 kilograms of left and right, and this mode can not meet the dismounting of shop bolt in composite assembling die.
Summary of the invention
The purpose of this utility model is to solve wasting time and energy of existing while implementing dismounting for assembling die at present, and dismounting is difficult for, with problems such as very large impulsive force, insufficient spaces, and a kind of pin removal is provided.Technical solution of the present utility model is, pin removal comprises bracing frame 1, nut 3, the axle 2 of pulling pin, screw 4, the axle 2 of pulling pin is a screwed screw mandrel, a bayonet socket 7 is installed in pull pin one end of axle 2, bracing frame 1 is by gripper shoe, fixing two piece pillars vertical with gripper shoe form, on bracing frame 1, offer and can pass for the screw mandrel of the axle 2 of pulling pin, and the through hole between two pillars, pull pin axle 2 through through hole and be equipped with the nut 3 that can offset with bracing frame 1, the nut of screw 4 packs in the fluting of bayonet socket 7 of the axle 2 of pulling pin.
The bayonet socket of the described axle 2 of pulling pin is three-back-shaped, one side the fluting that makes screw 4 screw mandrels pass that offers being connected with screw 4.
Spacing between the bayonet socket of described bracing frame 1 and the axle 2 of pulling pin is less than the width of bayonet socket.
The advantage the utlity model has and beneficial effect: the utility model has solved the problem that existing impacting type pin removal needs larger shock space, by lever principle, realize, effectively reduced the ARTIFICIAL FORCE in shop bolt demolishing process, time saving and energy saving, simple in structure, volume is little, reasonable, result of use good, is applicable to the dismounting of shop bolt in various assembling dies; When the utility model is dismantled for field of compound material mould therefor tool shop bolt, can not produce very large impact to multiple material product, avoid clashing into the generation that composite product is produced to the defects such as hole, layering.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that and reading after this reality has the content of novel instruction, those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally.
Pin removal comprises bracing frame 1, nut 3, the axle 2 of pulling pin, screw 4, the axle 2 of pulling pin is a screwed screw mandrel, a bayonet socket 7 is installed in pull pin one end of axle 2, bracing frame 1 is by gripper shoe, fixing two piece pillars vertical with gripper shoe form, on bracing frame 1, offer and can pass for the screw mandrel of the axle 2 of pulling pin, and the through hole between two pillars, pull pin axle 2 through through hole and be equipped with the nut 3 that can offset with bracing frame 1, the nut of screw 4 packs in the fluting of bayonet socket 7 of the axle 2 of pulling pin, spacing between the bayonet socket of bracing frame 1 and the axle 2 of pulling pin is less than the width of bayonet socket, the revolving force producing when preventing rotating nut 3 is by bayonet socket driven rotary.
During use, the screw mandrel of screw 4 is threaded fixing with the screw on shop bolt 5 end faces; The nut of screw 4 is packed in the fluting of axle 2 bayonet sockets 7 of pulling pin, adjusting nut 3 makes bracing frame 1 vertically stand on the surface of assembling die 6 again; Relend and help spanner, 3 pairs of bracing frames of turn nut 1 produce pressure, and be transmitted on assembling die by bracing frame, meanwhile, the screw mandrel of the axle 2 of pulling pin outwards moves, and outwards draws shop bolt 5 to be torn open, like this, assembling die 6 and shop bolt 5 to be removed are subject to respectively the active force of opposite direction, make to produce relative motion between shop bolt 5 and assembling die 6, and then realize the dismounting of shop bolt 5 from assembling die 6.In whole process, by lever principle, realize, effectively reduced the ARTIFICIAL FORCE in shop bolt demolishing process.
