Abstract
The utility model provides a chasing bar in a mould, and relates to the technical field of machining. An upper mould is internally provided with a stripper plate, a punch head, a hole flanging punch head and a bending concave mould; a lower mould is internally provided with a buoyancy lift plate, a spring, a buoyancy lift pin, a punching concave mould, a hole flanging concave mould and a bending convex mould. The chasing bar is characterized in that a worm wheel is internally provided with a tapping module in the mould and a worm, the worm is meshed with the worm wheel which is meshed with a gear 1, the gear 1 is meshed with a gear 2, and a screw tap is arranged on a shaft of the gear 2. According to the chasing bar, the tapping module is integrated with a punching mould, the up-and-down motion of a slide block of a punching machine is converted into the spiral motion of the screw tap, and the screw tap synchronously enters a material belt when the mould downwards moves, so that the tapping can be achieved; and the screw tap synchronously withdraws out of the material belt when the mould upwards moves, so that the aim of synchronous tapping during punching can be achieved. A threaded hole can be directly and synchronously formed when the mould is punched, so that the secondary operation can be effectively avoided, the work efficiency can be improved, the machining technology of metal stamping parts can be thoroughly changed, and the chasing bar is simple in structure, convenient to operate, and high in work efficiency, thereby being applicable to various metal plate tapping parts.
Description
Technical field
The utility model relates to the Machining Technology field, and is specifically a kind of for sheet metal parts such as automobile, five metals electronic products, carries out fast the integrated mould internal tapping device of hole processing in to part punching processing.
Background technology
At present, the die industry of China is in the stage of a develop rapidly, uses formed in mould nearly 60%-90% in the modern industry articles for use, especially in fields such as automobile, electronics, electrical equipment.And have advantages of that because of mould molding other processing modes such as high accuracy, high complexity, high uniformity and high efficiency are incomparable, so the development level of Die Industry has become the important symbol of weighing manufacture level gradually.But for the hole processing of part, mostly adopt in the industry first by the Dies ' Blanking forming hole, then on tapping machine the processing method of moulding screw thread, efficient is low, production cost and percent defective are high.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of mould internal tapping device, traditional mould punching and Tapping Technology is combined, with the purpose that realizes reducing production costs, increasing work efficiency.
For achieving the above object, in patrix of the present utility model, stripper plate, drift, hole flanging punch, bending female die are housed; Buoyance lift plate, spring, floating pin, punching concave die, hole flanging die, bending punch are housed in counterdie; It is characterized in that: mould internal tapping module and worm screw are housed in turbine, and worm screw is meshed with turbine, turbine and gear one engagement, and gear one and gear two engagements, screw tap is contained on the axle of gear two.
Operation principle of the present utility model is keep tapping process and punching course synchronous consistent, and when namely punch press (mould) is descending, the screw tap forward is shot the strip bottom outlet, and when up, screw tap reverses and withdraws from strip tooth hole.Therefore, the rectilinear motion of the upper and lower stroke of punch press synchronously need to be converted into the positive and negative rotation motion of screw tap, and the conversion of motion must realize by the turbine and worm transmission.Therefore, to select suitable turbine and worm movement conversion mechanism be the basis of realizing mould internal tapping principle in design.
The utility model is combined as a whole tapping module and diel, be converted to the screw of screw tap by moving up and down of slider of punch, screw tap synchronously enters strip when mould is descending, realizes tapping, synchronously withdraw from strip when up, reach the purpose of synchronous threading when punching press.
The utility model compared with prior art, traditional punching press and Tapping Technology are combined, screwed hole can be in mould punching direct synchronous forming, effectively avoid secondary operation, improved operating efficiency, thoroughly changed the processing technology of hardware stamping spare, simple in structure, easy to operate, high efficiency can be applicable to various panel beating tapping parts.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, stripper plate 1, drift 8, hole flanging punch 9, bending female die 11 are housed in patrix 18; Buoyance lift plate 2, spring 14, floating pin 16, punching concave die 12, hole flanging die 13, bending punch 15 are housed in counterdie 19; Mould internal tapping module 10 and worm screw 4 are housed in turbine 17, and worm screw 4 is meshed with turbine 17, turbine 17 and gear one 6 engagements, and gear 1 and gear 27 engagements, screw tap 5 is contained on the axle of gear 27.
The course of work of the present utility model.
The first step, punching: patrix 18 is descending, and stripper plate 1 is pushed down strip 3, completes the punching action under drift 8 and punching concave die 12 effects, and mould 18 is up, and strip 3 is fed forward.
Second step, hole flanging: patrix 18 is descending, and stripper plate 1 is pushed down strip 3, completes the hole flanging action under hole flanging punch 9 and 13 effects of hole flanging die, and patrix 18 is up, and strip 3 is fed forward.
The 3rd step, tapping: patrix 18 is descending, drives worm screw 4 and moves downward, and by the engagement of worm screw 4 with turbine 17, converts the vertical motion of worm screw 4 to turbine 17 rotatablely move, and turbine 17 is through gear one 6 driven gears 27 rotations, and then drives screw tap 5 rotations.Whole tapping process is divided into six stages: one, punch press moves downward from top dead-centre, stripper plate 1 moves downward, and during strip 3 was carried, worm screw 4 moved downward, in screw tap 5 dry runs of mould internal tapping module 10, buoyance lift plate 2 floats at the effect lower support strip 3 of spring 14; Two, punch press moves downward from top dead-centre, and stripper plate 1 moves downward, and strip 3 stops carrying, the tapping machine screw tap 5 beginning tapping of mould internal tapping module 10, and buoyance lift plate 2 floats at the effect lower support strip 3 of spring 14; Three, punch press moves downward from top dead-centre, and stripper plate 1 presses buoyance lift plate 2 to move downward, and screw tap 5 continues tapping; Four, punch press is to bottom dead centre, and screw tap 5 stops tapping, and stripper plate 1 presses buoyance lift plate 2 to move downward end; Five, punch press moves upward from bottom dead centre, and strip 3 is carried and stopped, and screw tap 5 tapping are moved back in tooth, and stripper plate 1 presses buoyance lift plate 2 to move upward with floating pin 16; Six, punch press moves upward from bottom dead centre, and strip 3 is carried and stopped, and screw tap 5 tapping are moved back in tooth, and stripper plate 1 leaves buoyance lift plate 2.
The 4th step, bending: patrix 18 is descending, completes the bending operation under the effect of bending female die 11 and bending punch 15.
