Abstract
The utility model discloses a punching die for forgings of railway clamping boards, comprising an upper die plate and a female die, wherein a die shank is fixedly arranged at the upper end of the upper die plate; a punch head fixing plate is fixedly arranged at the lower end of the upper die plate; a punch head is fixedly arranged at the lower end of the punch head fixing plate; a branch pipe is fixedly arranged at the upper end of the female die; a stripper plate is fixedly matched with the upper end of the branch pipe; a mold cavity corresponding to the punch head is arranged at the upper end of the female die; and material leaking holes are formed below the mold cavity. According to the utility model, the railway clamping boards are formed via punching after the forgings of the railway clamping boards are subjected to hot forging, so that the punching accuracy of the railway clamping boards is high and the forming efficiency is increased.
Description
Technical field
The utility model relates to a kind of for railway clamp punching forgings mould.
Background technology
Blanking die is the mould that material production is separated along the outline line that seals or open wide.Such as blanking die, perforating die, knife edge die, notch die, edger, parting die etc.After the present cantilever base body process forge hot, the shape basic forming of cantilever base body, but dimensional accuracy does not still reach the dimensional requirement of design, need to carry out next step Blanking Shaping and process.For the railway clamp, normally adopt hot-forging forming, pass through again punching die stamping-out type hole.
The utility model content
The purpose of this utility model provides a kind of for railway clamp punching forgings mould, after the forge hot of railway clamp forging process, and railway clamp punching moulding, railway clamp punching precision is high, and shaping efficiency improves.
The technical solution of the utility model is as follows:
A kind of for railway clamp punching forgings mould, comprise cope match-plate pattern, former, the upper end of cope match-plate pattern is installed with die shank, the lower end of cope match-plate pattern is installed with punch fixing plate, the lower end of punch fixing plate is installed with drift, and the upper end of former is fixed with arm, and the upper end secure fit of arm has stripper, the upper end of former has the die cavity corresponding with drift, and the below of die cavity has Lou material mouth.
Described leakage material mouth has two, and a leakage material mouthful bottom is round table-like.
Railway clamp forging of the present utility model is put into the railway clamp in the die cavity of former through after the forge hot, the downward punching press of drift, thereby railway clamp punching moulding, and railway clamp punching precision is high, and shaping efficiency improves.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, a kind of for railway clamp punching forgings mould, comprise cope match-plate pattern 1, former 2, the upper end of cope match-plate pattern 1 is installed with die shank 3, the lower end of cope match-plate pattern 1 is installed with punch fixing plate 4, the lower end of punch fixing plate 4 is installed with drift 5, the upper end of former 2 is fixed with arm 6, the upper end secure fit of arm 6 has stripper 7, the upper end of former 2 has the die cavity corresponding with drift 8, the below of die cavity 8 has Lou expects mouth 9, and leaking material mouth 9 has two, and leakage expects that mouthful 9 bottoms are round table-like.
