Abstract

A pipe clamp post forming die comprises an upper die plate, a screw I, a die shank, a male die fixing plate, a guide sleeve, a guide column, a lower die plate, a screw II, a female die and a male die; the male die fixing plate is fixed below the upper die plate through the screw I; the male die is a cylinder, the upper end of the male die is provided with a square opening, and the male die fixing plate is arranged on the outer side of the male die in a sleeved mode; the guide sleeve is fixed below the upper die plate, and the guide column is fixed above the lower die plate and is in relatively sliding fit with the guide sleeve; the lower die plate is connected with the female die above the lower die plate through the screw II, and the female die is arranged below the male die fixing plate. When the pipe clamp post forming die is applied, location is accurate in a machining process, and bending deviation is small. In addition, the pipe clamp post forming die is simple in structure, and easy to assemble and operate.

Description

A kind of pipe clamp post forming mould

Technical field

The present invention relates to a kind of mechanical workpieces production, relate in particular to a kind of pipe clamp post forming mould.

Background technology

Pipe clamp is at formative stage, rely on the shape and size of the mobility change workpiece of material, through one-time formed pipe clamp, its bending degree needs the post forming retrofit, pipe clamp is done to bending for the second time and 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 post forming mould, comprise cope match-plate pattern, screw I, die shank, punch retainer, guide pin bushing, guide pillar, lower bolster, screw II, die, punch;

Cope match-plate pattern is fixing thereunder by punch retainer by the screw I;

Punch is circular cylinder, and there is a square aperture its upper end, and described punch retainer is sleeved on the outside of described punch;

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 is arranged on the below of described punch retainer.

The die steel material of described a kind of pipe clamp post forming 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 post forming 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: 4011, cope match-plate pattern, 4021, the screw I, 4031, die shank, 4041, punch retainer, 4051, guide pin bushing, 4061, guide pillar, 4071, lower bolster, 4022, the screw II, 4081, die, 4091, punch.

The specific embodiment:

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

A kind of pipe clamp post forming mould, comprise cope match-plate pattern 4011, screw I 4021, die shank 4031, punch retainer 4041, guide pin bushing 4051, guide pillar 4061, lower bolster 4071, screw II 4022, die 4081, punch 4091;

Cope match-plate pattern 4011 is fixing thereunder by punch retainer 4041 by screw I 4021;

Punch 4091 is circular cylinder, and there is a square aperture its upper end, and described punch retainer 4041 is sleeved on the outside of described punch 4091;

The below of described cope match-plate pattern 4011 is fixed with guide pin bushing 4051, and guide pillar 4061 is fixed on the top of lower bolster 4071, and described guide pillar 4061 coordinates with guide pin bushing 4051 relative slidings;

Described lower bolster 4071 is connected with the die 4081 of its top by screw II 4022, and described die 4081 is arranged on the below of described punch retainer 4041.

Pipe clamp post-forming process process is as follows:

1, the pipe clamp post forming mould is fixed on forcing press;

2, the pipe clamp plate is sleeved on to the upper surface of punch 4091;

3, start forcing press, punch 4091 is descending with cope match-plate pattern 4011, in the descending process of punch 4091, with die 4081, presses, and die 4081 is fixing, and the middle semicircle to the waveform pipe clamp in the descending process of punch 4091 pressurizes;

4,, after Workpiece shaping, punch 4091 resets with forcing press.
