Embodiment 1

[0059] 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

[0078] 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

[0093] 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:

[0094] (1) Raw material preparation for rough

[0095] 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;

[0096] (2) Annealing treatment of forging blank

[0097] Anneal the forged blank obtained in step (1) through an annealing furnace, the annealing temperature is 810°C, the annealing time is 3.5 h, cool to 250°C in the annealing furnace, hold for 0.8h, and then air cool to room temperature;

[0098] (3) Initial processing of forging blanks

[0099] Process the forged blank in step (2) into the primary shape of the mold on the machine tool, leaving a margin of 1.5mm on each side;

[0100] (4) Heat treatment of the mold

[0101] The mold obtained by machining in step (3) wa...

Abstract

The invention discloses a one-time forming mould for a safe case sideboard and using and machining methods thereof and belongs to the field of mould design. The one-time forming mould comprises an upper mould assembly provided with upper moulds and a lower mould assembly provided with lower moulds; the number of the upper moulds is two and the two upper moulds are arranged symmetrically in the upper mould assembly; the lower ends of the upper moulds are stamping ends; and the lower moulds are provided with stamping grooves matched with the stamping ends of the upper moulds. The one-time forming mould for the safe case sideboard has the advantages that the safe case sideboard can be machined at a time; precision is high; secondary manual treatment is not needed; the surface of a workpiece is not damaged; operation is convenient; and cost is low. According to the using method of the one-time forming mould for the safe case sideboard, the safe case sideboard can be machined quickly and efficiently, bending efficiency is high and finished product quality is good. The machining method of the one-time forming mould for the safe case sideboard is used for machining the upper moulds and the lower moulds; forging is conducted first; then the shape of every part is machined; next, accurate grinding is conducted; and finally assembling is conducted. A special heat treatment process is adopted, so that hardness, toughness and abrasion resistance of the mould meet the process requirements. After machining and using exceed ten thousand times, the mould is still normal, and service life is long.

Description

technical field [0001] 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 side plate of a safe, and more specifically relates to a one-time forming mold for a side plate of a safe and its use and processing method. Background technique [0002] 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 through the mutual guidance of the upper mold and the lower mold of the bending machine. In the actual production process, the enterprise will configure the lower mold with different groove angles according to the shape or size of the formed...
