Embodiment 1

[0060] Such as figure 2 , image 3 As shown, a one-time forming mold for a side plate of a safe in this embodiment includes an upper mold assembly and a lower mold assembly; wherein, the upper mold assembly includes an upper mold base 1 and an upper mold 3, and the upper mold base 1 is The upper mold fixed block 2 is installed, and the upper mold 3 has two, and the two upper molds 3 are symmetrically arranged on the left and right ends of the upper mold fixed block 2 respectively; and the upper mold 3 is fixed on the upper mold fixed block 2 groove, and is detachably connected to the upper mold fixing block 2 by bolts, and the design of the upper mold fixing groove makes the installation of the upper mold 3 convenient and accurate in positioning. The lower end of the upper die 3 is a stamping end, which is composed of a first vertical surface 301, a first horizontal surface 302, a second vertical surface 303, a second horizontal surface 304 and an inclined surface 305 from o...

Embodiment 2

[0079] Although the mold and method in Example 1 can be used to complete the bending process of the side plate of the safe, there is a problem, that is, the number of times of use is too large, and the working parts of the upper mold 3 and the lower mold 6 are due to greater force. , easily damaged, resulting in the need to replace the mold after a period of use. It has been proved by practice that the upper mold processed by ordinary materials and heat treatment processes will easily appear between the second vertical surface 303 of the upper mold 3 and the second vertical surface 303 when it is used for about 2300 times. The junction of the two horizontal planes 304 and the junction of the second horizontal plane 304 and the inclined surface 305 appear cracks and abrasions. Similarly, the junctions of the first transverse groove surface 602 and the second vertical groove surface 603 also appear cracks and abrasions. Although the above factors have been considered in the struc...

Embodiment 3

[0094] A kind of processing method of special bending mold for safe door frame plate of the present embodiment, lower mold 6 is processed, and its steps are:

[0095] (1) Raw material preparation for rough

[0096] It is made by forging blank. The composition and mass percentage of the forging blank are: C 0.4%, Si 0.3%, Mn0.65%, S≤0.023%, P≤0.021%, Cr 1.4%, Mo 0.42%, ZrO 2 0.1%, the balance is Fe;

[0097] (2) Annealing treatment of forging blank

[0098] Annealing the forged blank obtained in step (1) through an annealing furnace, the annealing temperature is 810°C, the annealing time is 3.5h, cooled to 250°C in the annealing furnace, kept for 0.8h, then air-cooled to normal temperature;

[0099] (3) Initial processing of forging blanks

[0100] The forging blank in step (2) is processed into the primary shape of the mold on the lathe, and each side retains a margin of 1.5mm;

[0101] (4) Heat treatment of the mold

[0102] The mold obtained by machining in step (3) wa...

Abstract

The invention discloses methods for using and machining a one-time forming die for a safety box side plate and belongs to the field of die design. The method for using the die comprises the steps thatan upper die assembly and a lower die assembly are assembled firstly; then the lower die assembly is fixed to a working table of a hydraulic machine; then the upper die assembly is hoisted to the lower die assembly, and the stamping groove faces of the upper die assembly and the lower die assembly are tightly matched; then the upper die assembly is fixed to a sliding block of the hydraulic machine; and finally, a workpiece on a lower die is subjected to bending forming through the upper die assembly. According to the method for using the die, the safety box side plate can be quickly and efficiently machined, the bending efficiency is high, and the quality of a finished product is good. The method for machining the die is used for machining an upper die and the lower die and comprises thesteps that forging is conducted firstly; the shapes of all parts are machined; then fine grinding is conducted; and finally assembling is conducted. A special heat treatment process is adopted, thus the hardness, toughness and abrasion resistance of the die meet the process requirements, the die is still normal after being machined and used for more than ten thousand times, and the life is long.

Description

[0001] This application is a divisional application of a patent application titled: A one-time forming mold for safe side panels and its use and processing method, the application number is: 2016110811331, and the application date is: November 30, 2016. technical field [0002] The invention belongs to the field of mold design, and in particular relates to a mold capable of one-time bending and forming of a safe side plate, and more specifically relates to a use and processing method of a one-time forming mold for a safe side plate. Background technique [0003] The bending machine mold is a tool used by the bending machine to process and form the sheet. This tool is composed of various parts, and different molds have different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Under the action of the pressure of the bending machine, the blank becomes a workpiece with a specific shape and size...
