Description

Slidable automatic guiding device for blank making by using punch press

Technical Field

The utility model relates to a field of integral key shaft base, concretely relates to utilize slidable automatic guiding device of punch press base.

Background

The prior art uses a 250T punch press to perform vertical forging blank making, and the structure is shown in FIG. 1. And after the round steel is placed into a cavity of the lower die for blank making, the upper die is pressed downwards, and the round steel is partially upset to be made into a desired shape. The prior art mainly has the following defects: the effective height of the punch slide to the work table is limited by the device, for example, the effective height H of a 250T punch used by people is 570mm, and because of the limitation, the length of round steel which can be put into a cavity is limited to be below 250mm (slightly different according to the thicknesses of an upper die and a lower die). That is to say, we can only make blanks for some shorter materials, and the longer materials cannot be put in, but actually, many steel blanking specifications exceed 300mm, for example, the blanking length of the NBCK4W-4870-BC spline shaft which needs to be forged frequently is 330mm, so that the blanks cannot be made on a punch press, and the production is greatly limited.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of prior art existence, and provide a slidable automatic guiding device who utilizes punch press system base.

The purpose of the utility model is accomplished through following technical scheme: this kind of utilize slidable automatic guiding device of punch press base, mainly include the punch press top shoe, the punch press workstation, ejector pin under the punch press, adjustable last mould, the lower mould, a pedestal, the ejector pin, the cylinder, adjustable last mould is connected to punch press top shoe lower extreme, punch press workstation top installation base, installation lower mould in the base, lower mould outside cover is equipped with the snap ring, the snap ring is connected to cylinder on one side, the cylinder drives the lower mould and slides on the base, the axis of lower mould and the punch press in the punch press workstation ejector pin under coaxial, the ejector pin top sets up the ejector pin under the punch press, the ejector pin top is located the counter bore of base.

The adjustable upper die, the lower die, the ejector rod and the punch lower ejector rod are coaxially arranged.

The adjustable upper die is designed into an upper part and a lower part which are in threaded fit.

The utility model has the advantages that: the utility model changes the former blank making mode, so that the lower blank making die can slide, steel is put into the die outside the equipment, the limitation of the equipment height is ingeniously solved, the limitation of the existing equipment height is broken through, and the product with longer blanking length can be vertically forged on a 250T punch press; the method is used for manufacturing the NBCK4W-4870-BC spline shaft blank in actual production, all elements are matched smoothly, the problem that long steel cannot be manufactured by a punch in the prior art is perfectly solved, the length of forged steel is increased from 250mm to 400mm, the requirement of the existing product for manufacturing the blank can be met, a large production problem is solved, the possibility that the long shaft type forge piece cannot be forged into the blank in a vertical mode is achieved, and meanwhile the quality of the forge piece is improved.

Description of reference numerals: the device comprises a punch upper slide block 1, a blank making upper die 2, steel 3, a blank making lower die 4, a punch workbench 5, a punch lower ejector rod 6, an adjustable upper die 7, a lower die 8, a clamping ring 9, a base 10, an ejector rod 11, a cylinder 12 and a counter bore 101.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

example 1: as shown in the attached drawings, the slidable automatic guiding device for making blanks by using the punch mainly comprises a punch upper sliding block 1, a punch workbench 5, a punch lower ejector rod 6, an adjustable upper die 7, a lower die 8, a clamping ring 9, a base 10, an ejector rod 11, a cylinder 12 and a counter bore 101, wherein the lower end of the punch upper sliding block 1 is connected with the adjustable upper die 7, the base 10 is installed above the punch workbench 5, the lower die 8 is installed in the base 10, the clamping ring 9 is sleeved outside the lower die 8, the clamping ring 9 is connected to the cylinder 12 beside, and the cylinder 12 drives the lower die 8 to slide on the base 10, so that steel 3 is placed into a cavity of the lower die 8 outside the punch, the lower die 8 and the steel 3 are pulled back together, then the blanks are made, and semi-automatic operation is realized, and. The axis of the lower die 8 is coaxial with a lower punch ejector rod 6 in the punch workbench 5, an ejector rod 11 is arranged above the lower punch rod 6, and the top end of the ejector rod 11 is located in a counter bore 101 of the base 10.
