Description

Pin puller

Technical Field

The utility model relates to a mould trade technical field, in particular to pin puller.

Background

The pin puller is used for pulling out a tool of a cotter in a fitting or a die, however, the existing pin puller still has some unreasonable factors in the use process, the existing authorization number is CN 206536414U, and the patent name is a convenient and fast pin puller, which solves the problem that a screw hole part in the die can be quickly disassembled from tools, and can quickly change the size of the screw on the part to take out the screw, so that the parts tightly matched in the die and the workpieces such as standard screw pieces can be conveniently and fast taken out, the cost can be saved, the labor is reduced, but the convenient and fast pin puller also has the following defects that the pin parts and the standard screw pieces on the surface of the die cannot be conveniently and fast taken out, the application range is narrow and the use is inconvenient.

Disclosure of Invention

To the present situation of the above prior art, the utility model aims to solve the technical problem of providing a pin puller that application range is wide, convenient to use, can take out the inside and outside pin part of mould and standard screw spare fast.

The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a pin puller, includes the body, the body includes pin puller and pin puller head, the pin puller head welds in pin puller rear end, pin puller front end is provided with broach cover and meson, the meson is fixed in the broach cover, the meson with broach cover threaded connection, because the pin puller head welds in pin puller rear end, pin puller front end is provided with broach cover and meson, the meson is fixed in the broach cover, when the specification of the screw of the pin top inside and outside the mould is M6-M16, only need twist the broach cover from the pin puller off, then change corresponding needs meson and be used for collocation mould the inside and the pin spare of outside to a convenient and fast's pin puller still has following not enough among the prior art, can't take out convenient and fast to the pin part and the standard screw spare that the mould exposes the surface, therefore, the pin puller has the advantages of being wide in application range and convenient to use, pin parts and standard screw parts inside and outside a die can be quickly taken out, the meson is in threaded connection with the pull pin sleeve, and the structure of threaded connection between the outer part of the meson and the pull pin sleeve can prevent the meson from shaking in the pulling process after the meson is connected to the pin parts needing the inside and the outside of the external die, so that the stability in the pulling process is effectively improved.

Preferably, the shift out the round pin mobile jib middle-end and be provided with and hold the hammer, it cup joints to hold the hammer on the shift out the round pin mobile jib, owing to hold the hammer cup joint on the shift out the round pin mobile jib, can let the user hold and hold hammer rebound to the shift out the round pin pole head to realize the slow purpose of pulling out the pin part and the standard screw spare of mould the inside and outside of pin puller, consequently have convenient to use's characteristics.

Preferably, a threaded hole is formed in the rear end of the pull pin sleeve, the pull pin sleeve is connected with the front end of the pull pin main rod through the threaded hole, and the pull pin sleeve is connected with the front end of the pull pin main rod through the threaded hole, so that when the meson needs to be replaced, a user only needs to screw the pull pin sleeve off from the threaded hole of the pull pin main rod and then replace a pin piece which correspondingly needs the meson to be used for matching the inside and the outside of a mold, the purpose that the specification of the screw is M6-M16 is rapidly taken out is achieved, and the pull pin sleeve has the characteristic of wide application range.

Preferably, a through hole is formed in the front end of the pull pin sleeve and is located at the front end of the meson, and the through hole is located at the front end of the meson and can prevent the meson from falling outside from the inside of the pull pin sleeve, so that the pull pin sleeve has the characteristic of positioning.

Compared with the prior art, the utility model has the advantages of: the utility model discloses a welding of pin pulling rod head is in pin pulling mobile jib rear end, pin pulling mobile jib front end is provided with cotter bush and meson, the meson is fixed in the cotter bush, when the specification of the screw at the round pin top of mould the inside and outside is M6-M16, only need to twist the cotter bush from the pin pulling mobile jib and twist off, then trade the corresponding round pin spare that needs the meson and be used for arranging mould the inside and outside, thereby solved a convenient and fast's pin puller among the prior art and still had following not enough, can't expose pin part and the standard screw spare on surface to the mould and carry out convenient and fast and take out, consequently, application range is narrow and use inconvenient problem, consequently, this pin puller has application range extensively, convenient to use, can take out the inside and outside pin part and the standard screw spare of mould fast, simultaneously the meson with pin pulling sleeve threaded connection, this meson outside and pulling sleeve threaded connection's structure can prevent that meson internal connection from needing outside mould the inside and outside mould the outside After the pin piece is pulled out, the pin piece is shaken in the pulling-out process, so that the stability in the pulling-out process is effectively improved, the hand-held hammer is sleeved on the pin pulling main rod, a user can hold the hand-held hammer to move upwards to the pin pulling rod head, so that the purpose of slowly pulling out pin parts and standard screw pieces inside and outside a mold by the pin pulling device is realized, the pin pulling device has the characteristic of convenient use, meanwhile, the pin pulling sleeve is connected with the front end of the pin pulling main rod through a threaded hole, when the meson needs to be replaced, the user only needs to screw the pin pulling sleeve off from the threaded hole of the pin pulling main rod and then replaces the pin piece which needs the meson correspondingly to be used for matching the inside and the outside of the mold, so that the purpose of quickly taking out the specification of the screw from M6 to M16 is realized, the device has the characteristic of wide use range, and the through hole is positioned at the front end of the meson, thereby having the characteristic of positioning.
