Abstract
The invention discloses a cold-heading die for a sealing bolt, comprising a fixed die and a movable die, wherein a die cavity for installing the sealing bolt is disposed in the fixed die; the movable die comprises a movable die body and a die cover; a machining block is disposed at one end matching with the fixed die of the movable die body; the die cover is disposed at one end away form the matched place with the fixed die of the movable die body; an ejector rod channel is disposed in the movable die body; an ejector rod is disposed in the ejector rod channel; one end close to the fixed die of the ejector rod penetrates the machining block to eject the sealing bolt while the other end stretches out of the die cover; the ejector rod is sleeved with an ejector block and a pressure spring outside the ejector rod channel part; and one end of the pressure spring resists the ejector block while the other end resists and matches with the die cover. The ejector rod of the cold-heading die for a sealing bolt disclosed by the invention always resists the machined sealing bolt when the movable die retreats, which prevents the end close to the movable die of the sealing bolt from falling off due to the losing of support, so that a manipulator has enough time to take off the sealing bolt to enter into the next production phase conveniently.
Description
Technical field
The present invention relates to mould applications, be specifically related to a kind of sealing bolt cold-heading mould.
Background technology
Sealing bolt generally is used for two parts are connected and the assurance sealing, the processing method of this sealing bolt generally adopts the mould of cooperation to carry out cold-heading processing and makes, general this cold-heading method for processing adopts and at normal temperatures the metal bar material upsetting formation is processed into needed bolt, generally metal bar material is carried out local material and upsets.After sealing bolt processes, need enter next production and processing link with from mould, taking off in the manipulator sealing bolt that cold-heading is good.The mould of sealing bolt generally comprises fixed die and mobile mould, after finishing cold heading technique, mobile mould is removed, manipulator carries out pickup, because when mobile mould is backed out, one end of sealing bolt loses support, be easy in the die cavity of fixed die, drop, therefore people often need the time that mobile mould is pushed open is controlled in actual mechanical process, if mobile mould is pushed open too early, then sealing bolt drops easily, if mobile mould is backed out too early, then manipulator will be run into mould when getting sealing bolt, and is very inconvenient.
Summary of the invention
The objective of the invention is to: in order to overcome the deficiencies in the prior art, the invention provides a kind of sealing bolt cold-heading mould, avoid when sealing bolt is taken in process and after the processing, dropping, process more convenient.
To achieve these goals, the present invention has adopted following technical scheme: a kind of sealing bolt cold-heading mould, comprise fixed die and mobile mould, be provided with the die cavity of laying for sealing bolt in the described fixed die, mobile mould comprises mobile mould body and die cap, the end that mobile mould body cooperates with fixed die is provided with processing block, die cap is arranged on the end of mobile mould body away from itself and fixed die cooperation place, be provided with the push rod passage in the mobile mould body, be provided with push rod in the push rod passage, one end of the close fixed die of push rod passes processing block and withstands sealing bolt, the other end stretches out die cap, push rod is positioned at the push rod channel part and is arranged with jacking block and stage clip outward, and stage clip one end props up jacking block, and the other end offsets with die cap and cooperates.
As preferably, described push rod is provided with step, and described jacking block offsets near a side and the step of fixed die, and the formation push rod cooperates with the spacing of jacking block.After adopting above-mentioned preferred version, because jacking block is subjected to the effect of offseting of stage clip, jacking block can travel forward, on the push rod step is set after, can carry out spacingly to jacking block, avoid the jacking block transition to travel forward, destroy mobile mould internal structure.
As preferably, the processing block in the described mobile mould is provided with projection away from an end of fixed die, and projection and the jacking block formation top that offsets can be equipped with the spacing of mobile mould body.After adopting above-mentioned preferred version, mobile mould withdraws from the back push rod and continues to withstand sealing bolt, until manipulator sealing bolt is taken away, and push rod can move forward, and at this moment, jacking block forms spacing the cooperation with projection, avoids the jacking block transition to travel forward, and destroys mobile mould internal structure.
As preferably, described jacking block comprises the jacking block boss, and described compression spring sleeve is located at outside the jacking block, and the jacking block boss of stage clip one end and jacking block offsets, and the other end and die cap offset.After adopting above-mentioned preferred version, compression spring sleeve is located at jacking block, avoids stage clip directly to be set on the push rod, and push rod is caused wearing and tearing.
As preferably, be provided with bolt jacking block and bolt stage clip in the die cavity of described fixed die, bolt stage clip and bolt jacking block want to, the counterpart of the other end and fixed die offsets.After adopting above-mentioned preferred version, can stretch into the position of mobile mould according to the work piece that actual conditions are regulated sealing bolt, more convenient.
The push rod of sealing bolt cold-heading mould of the present invention props up processed sealing bolt all the time when mobile mould is backed out, avoid sealing bolt to lean on an end of mobile mould to lose supporting and drop, thereby make manipulator have the enough time that sealing bolt is taken away and enter next production link, very convenient.
