Abstract

The invention discloses a pipe clamp one-time forming die which comprises an upper template, a screw I, a die handle, a male die, a guide sleeve, a guide column, a lower template, a screw II and a female die. The die handle is arranged above the upper template, one end of the screw I is embedded in the upper template, one end of the screw I is connected with the terrace die to fasten the terrace die to the lower portion of the upper template, and the lower surface of the terrace die is in the shape of waves. The guide sleeve is fixed to the lower portion of the upper template, the guide sleeve is fixed to the upper portion of the lower template, and the guide column is matched with the guide sleeve in a relatively-sliding mode. The lower template is connected with the hollowing die above the lower template through the screw II, and the upper surface of the hollowing die is in the shape of waves. According to the pipe clamp one-time forming die, positioning is accurate in the machining process, bending error is small, and the pipe clamp one-time forming die is simple in structure, and easy to assemble and operate.

Description

A kind of pipe clamp one-time-shaped mould

Technical field

The present invention relates to a kind of mechanical workpieces production, relate in particular to a kind of pipe clamp one-time-shaped mould.

Background technology

Pipe clamp is at formative stage, rely on the shape and size of the mobility change workpiece of material, one-shot forming is pipe clamp to be done to bending for the first time process, in prior art, defect due on general forming die structure, make location accurate not, and the bending error is larger, complicated mould is installed, operation is comparatively difficult, and cost is large.

Summary of the invention

The problems referred to above that exist for solving prior art, the present invention adopts following technical scheme:

A kind of pipe clamp one-time-shaped mould, comprise cope match-plate pattern, screw I, die shank, punch, guide pin bushing, guide pillar, lower bolster, screw II, die;

Die shank is equipped with in the top of cope match-plate pattern, and screw I one end embeds cope match-plate pattern, and an end is connected with punch, punch is fastened on to the below of cope match-plate pattern, and the lower surface of described punch is wavy;

The below of described cope match-plate pattern is fixed with guide pin bushing, and guide pillar is fixed on the top of lower bolster, and described guide pillar coordinates with the guide pin bushing relative sliding;

Described lower bolster is connected with the die of its top by the screw II, and described die upper surface is wavy.

The die steel material of described a kind of pipe clamp one-time-shaped mould is selected microalloy Cr12MoV mould steel, the Technology for Heating Processing of mould steel is: after hot rolling, be heated to 1050 ?1150 ℃ carry out solution treatment, be as cold as soon 600 ℃ proceed to 400 ?make it isothermal transformation in 700 ℃ of stoves, after machined, be heated to 900 ?950 ℃ of oil quenchings, finally 150 ?200 ℃ of tempering.

Each individual components that forms described a kind of pipe clamp one-time-shaped mould adopts Digit Control Machine Tool processing.

The invention has the beneficial effects as follows: the material selection microalloy Cr12MoV mould steel of punch and die, guaranteed die hardness, mould steel adopts above-mentioned Technology for Heating Processing, has reduced carbon emission, and quenching degree can be enhanced about more than once; The independent workpiece of Digit Control Machine Tool processing mold, improved the precision of independent workpiece; Independent workpiece high accuracy processing and overall construction design optimization, reasonability and the stability in the monolateral gap of the present invention have been improved, the gap of punch and die is remained between 0.01-0.02mm, adopt above technical scheme, accurate positioning in process, the bending error is little, and the present invention is simple in structure, is easy to assembling and operation.

The accompanying drawing explanation

Fig. 1 is front view of the present invention;

Fig. 2 is the top view of lower bolster.

In figure: 3011, cope match-plate pattern, 3021, the screw I, 3031, die shank, 3041, punch, 3051, guide pin bushing, 3061, guide pillar, 3071, lower bolster, 3022, the screw II, 3081, die.

The specific embodiment:

Below in conjunction with specific embodiment, the present invention is further described:

A kind of pipe clamp one-time-shaped mould, comprise cope match-plate pattern 3011, screw I 3021, die shank 3031, punch 3041, guide pin bushing 3051, guide pillar 3061, lower bolster 3071, screw II 3022, die 3081;

Die shank 3031 is equipped with in the top of cope match-plate pattern 3011, and screw I 3,021 one ends embed cope match-plate pattern 3011, one ends and are connected with punch 3041, and the lower surface that punch 3041 is fastened on to the described punch 3041 in below of cope match-plate pattern 3011 is wavy;

The below of described cope match-plate pattern 3011 is fixed with guide pin bushing 3051, and guide pillar 3061 is fixed on the top of lower bolster 3071, and described guide pillar 3061 coordinates with guide pin bushing 3051 relative slidings;

Described lower bolster 3071 is connected with the die 3081 of its top by screw II 3022, and described die 3081 upper surfaces are wavy.

Pipe clamp one-shot forming process is as follows:

1, the pipe clamp one-time-shaped mould is fixed on forcing press;

2, pipe clamp plate level is placed in to the upper surface of die 3081;

3, start forcing press, punch 3041 is descending with cope match-plate pattern 3011, in the descending process of punch 3041, with die 3081, presses, and the pipe clamp flitch is under the punching press of punch 3041, and middle rectangle long-bar metal plate is bent into wavy;

4,, after Workpiece shaping, punch 3041 resets with forcing press.
