Width-changeable steel bar stamping die

Abstract

The invention discloses a width-changeable steel bar stamping die which structurally comprises an upper stamping plate, a first limiting steel block, a lower stamping plate, a supporting transverse column, a steel diameter adjusting plate, a second limiting steel block, a lower abutting plate, telescopic columns and upper abutting rings. The four abutting rings are connected to four corners belowthe stamping plate through nails. The four telescopic columns are arranged and slidably connected to the lower portions of the upper abutting rings. A swing device is arranged on the structure, an upper hinge wheel at the top of the swing device can pull diameter adjusting frames at the two ends to move towards the middle, the ruler distance between the first limiting steel block and the second limiting steel block is decreased, then the diameter of a formed steel bar is controlled, and multiple functions are achieved by one machine. An anti-moving frame is arranged on the structure, after thedistance is adjusted by an adjusting arm, the adjusting arm can be supported and fixed through ejection pieces at the two ends, the phenomenon that a diameter adjusting frame slides away due to impact force in the punching process is avoided, and the diameter of the steel bar is more stable.

Description

technical field [0001] The invention relates to a stamping die for steel bars with variable width, which belongs to the field of dies. Background technique [0002] Steel rod is a material often used in building construction. It is a square block. Most of it is fired during production, but some can be stamped from waste materials. Stamping materials of different shapes In the shape of steel bars, it is more resource-saving, but when stamping steel bars, some difficult problems will be encountered. [0003] In the prior art, steel bars of one diameter can only be stamped out when stamping steel bars, and a set of equipment needs to be replaced when stamping steel bars of other widths, and it is relatively wasteful to set up multiple sets of stamping equipment for stamping steel bars resources, increasing costs. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a stamping die for steel strips w...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a stamping die for steel strips with variable width, so as to solve the problem that the prior art can only stamp out steel strips with one diameter when stamping steel strips, and stamp out other diameters when stamping steel strips. A set of equipment needs to be replaced when the width of the steel bar is large, and setting up multiple sets of stamping equipment for stamping the steel bar is a waste of resources and increases the cost.
