Abstract
The invention discloses a distortion controlling bend forming die comprising an upper template (01), an upper die (02), a lower template (05), a form cavity lower die (03), a screw rod assembly (04), and a clamp plate lower die (08); the upper template (01) and the upper die (02) are fixedly connected; the form cavity lower die (03) and the lower template (05) are fixedly connected; the clamp plate lower die (08) is connected in parallel with the form cavity lower die (03) through the screw rod assembly (04); the screw rod assembly (04) can be adjusted to enable the clamp plate lower die (08) to get close to or get away from the form cavity lower die (03); in the prior art, a bend end face normally recesses after the rectangular cross section tubing part is bended and formed; the distortion controlling bend forming die can solve said problems, is good in forming quality, can relatively save mass manual shape corrections, thus thoroughly solving the part forming quality problems.
Description
Technical field
The invention belongs to tubular object extruding frock field, relate to a kind of bending and forming mould controlling distortion.
Background technology
Square-section tubing bending forming is when using the general stretch bending method of tubing, method of going for a stroll to shape, generally use mould o ing i.e. press shaping die method, the method mould structure is simple, easily operate, production efficiency is high, save raw material, is relatively suitable for aviation panel beating scientific research and small serial production.Tubing press shaping die is to utilize the upper and lower mold pressing conjunction of the fixture for forming being arranged on pressing equipment to realize tube bending to shape.Tubing press shaping die frock is generally made up of upper and lower mould, and upper and lower mould is respectively provided with the shape angles of formation of parts, and upper mold is fixed on the upper table surface of pressing equipment, lower mold is fixed on the following table of pressing equipment.During shaping, preparing to shape placing part in lower mold, pressing equipment starts, and drives pressing equipment upper table surface descending, is bent the tubing that is placed in lower mold until fitting with lower mold, it is achieved part forming.Press shaping die tubing section easily produces distortion, for avoiding this phenomenon to produce, inside tubing, generally fill press shaping die after fine sand or low-melting alloy, but when shaping cross section still produce heave, the distortion such as depression, affecting part quality and service life, the aluminium alloy pipe big particularly with tubing height-to-breadth ratio is more easily generated distortion when to narrow section flexure..
Summary of the invention
The technical problem to be solved in the present invention is, invents a kind of bending and forming mould controlling distortion, improves the bending forming quality of square-section tubing part.
A kind of bending and forming mould controlling distortion is provided for solving the problems referred to above technical solution of the present invention, including cope match-plate pattern 01, upper mold 02, lower bolster 05, also include shape chamber lower mold 03, lead screw assembly 04, clamping plate lower mold 08, described cope match-plate pattern 01 is fixing with upper mold 02 to be connected, described shape chamber lower mold 03 is fixing with lower bolster 05 to be connected, described clamping plate lower mold 08 is connected with described shape chamber lower mold 03 side by side by lead screw assembly 04, reconciles described lead screw assembly 04 and described clamping plate lower mold 08 can be made close to or away from described shape chamber lower mold 03.
Preferably, described upper mold 02 is step-like structure with described shape chamber lower mold 03, when upper mold 02 is depressed into a certain degree, the terrace of appearing on the stage of shape chamber lower mold 03 contacts the leave from office terrace of described upper mold 02, limit the downward motion of described upper mold 02, between the leave from office terrace of appear on the stage terrace and the described shape chamber lower mold 03 of told upper mold 02, keep the space accommodating press-bending workpiece.
Bending sunken end face problem after the square-section tubing spares bend shaping that the mould that the present invention provides generally exists in efficiently solving industry, forming quality is good, saves substantial amounts of manual school shape accordingly, thoroughly solves part forming quality problems.
Accompanying drawing explanation
Specific embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings, wherein:
Fig. 1 is the bending forming schematic diagram of the present invention；
Fig. 2 is the version A-A view of inventive die.
Wherein: 01 is cope match-plate pattern, 02 is upper mold, and 03 is shape chamber lower mold, and 04 is lead screw assembly, and 05 is lower bolster, and 06 is signal before spares bend, and 07 is signal after spares bend, and 08 is clamping plate lower mold.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail:
Technological preparation:
Manufacturing bending die by product design, upper and lower mode structure, lower mold is with the shape chamber of square-section tubing width, and shape chamber is fabricated to the laterally-clamped Split type structure of clamping plate so that putting part, pickup, upper and lower mould matched moulds limited location device；
Manufacture:
Blanking；
Oil removing, removes square tube surface smut, impurity etc.；
Hair down is stung, and makes edge of materials smooth, it is to avoid injury operator, and scratches other products and mould；
The internal fine sand of filling of tubing supports；
Part is fixed; narrow for rectangle pipe material part cross section is placed in 03. shape chamber lower mold; 08. clamping plate lower mold is slided to 03. shape chamber lower mold under 04. lead screw assembly drives and is drawn close, and 03. shape chamber lower mold constitutes, with 08. clamping plate lower mold, the shape chamber that cross section narrow with rectangle pipe material is wide, makes to keep sliding with part and closes；
Bending forming, forcing press continues to come downwards to 02. upper mold shoulder after driving the 02. slow descending contact tubing part of upper mold being fixed on 01. cope match-plate pattern and 03. shape chamber lower mold shoulder contacts stops descending, and tubing is bent, and press shaping die terminates；
Inloading part; forcing press drives 02. upper mold being fixed on 01. cope match-plate pattern up, and 02. upper mold leaves the shape chamber that 03. shape chamber lower mold is constituted with 08. clamping plate lower mold, and clamping plate lower mold is slided with 03. shape chamber lower mold under 04. lead screw assembly drives and separated; guarantee that part nothing from mould pulls mould unloading, take out part；
Remove the internal filling of tubing；
Inspection, checks the quality of the products by drawing and associated specifications；
Oil removing, removes the greasy dirt etc. produced in the course of processing；
Labelling, marked product figure number, date of manufacture etc..
