Abstract
The invention discloses a machining method of an injection molding machine frame. The machining method comprises the first step of selecting boards, the second step of bending the boards, the third step of welding the boards into the frame and the fourth step of carrying out flatness machining on the frame, wherein the second step comprises the step of opening a seam at each bent position through laser. The injection molding machine frame produced through the machining method is high in flatness and position precision, and therefore the movement precision of moving components of an injection molding machine is improved.
Description
Technical field
A kind of processing method, particularly a kind of processing method of injection molding machine frame.
Background technology
Current domestic injection machine mainly contains vertical and horizontal two kinds; Wherein plain edition horizontal injection press accounts for dominant direction at injection molding machine of plastic.Frame, as composition injection machine profile vitals, is equally also have very large development space.The ubiquitous problem of current large size plastic jetting-moulding device frame: because frame body is larger, the situation of the ubiquity bulk deformation when assembly welding, the more difficult control of flatness on surface.Thus greatly have impact on speed of production and the quality of frame.In order to promote injection machine total quality, solve distortion and the difficult control problem of flatness, so be necessary to research and develop super smooth type frame.
Medium-and-large-sized common horizontal injection machine outer appearance part, it is primarily of 1, injection portion cover plate, and 2, moulding section cover plate, 3, frame composition.Its mid frame is an important building block, and it is that the moving component of injection machine provides a good support, keeps the kinematic accuracy of moving component above frame.Because the kinematic accuracy of frame to injection machine moving component serves very important effect, therefore frame itself is also higher to the requirement of dimensional accuracy, positional precision and flatness, but because frame body is larger, the control of the flatness on the bulk deformation when assembly welding and surface is more difficult.Thus greatly have impact on speed of production and the quality of frame.For this kind of situation, I sets about carrying out improveing and researching and developing from the processing technology of frame entirety at department, to solving the out-of-flatness that frame exists, the problem that positional precision is inadequate; Prior art is unresolved such problem also.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of processing method being applicable to injection molding machine frame, the frame flatness utilizing this to produce and positional precision high, thus improve the kinematic accuracy of injection machine moving component.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
The processing method of injection molding machine frame, comprising: step one: choose sheet material; Step 2: by sheet metal bending; Step 3: each sheet material is welded into frame; Step 4: the flatness of above-mentioned frame is processed; Step 2 comprises: a, in bending part laser open gap.
The processing method of aforesaid injection molding machine frame, the wide of gap is 0.25cm.
The processing method of aforesaid injection molding machine frame, the length in gap equals the length of installing hole.
The processing method of aforesaid injection molding machine frame, step 3 comprises: use turnbuckle to position, then based on automatic welding car, manual welding is that auxiliary welding manner welds.
The processing method of aforesaid injection molding machine frame, while carrying out step 3 welding, removes gap by the mode of Puttying, joint filling or polishing.
The processing method of aforesaid injection molding machine frame, step 4 comprises: use planer-type milling machine to carry out surperficial fine grinding to the frame after welding.
The processing method of aforesaid injection molding machine frame, frame is 1.6 through surperficial fine grinding rear surface roughness Ra, and surface planarity is less than or equal to 0.5.
Usefulness of the present invention is: the invention provides a kind of processing method being applicable to injection molding machine frame, the frame flatness utilizing this to produce and positional precision high, thus improve the kinematic accuracy of injection machine moving component.
Detailed description of the invention
Below in conjunction with specific embodiment, concrete introduction is done to the present invention.
The processing method of injection molding machine frame, comprising: step one: choose sheet material; The Q235 sheet material that the performances such as selection intensity, plasticity and welding can better coordinate; Step 2: by sheet metal bending; Step 3: each sheet material is welded into frame; Step 4: the flatness of above-mentioned frame is processed; Step 2 comprises: a, in bending part laser open gap; Preferred as one, the wide of gap is 0.25cm, and the length in gap equals the length of installing hole; Thus ensure that on the angle of bending and plate, installing hole is indeformable when bending, guarantee product complete after intensity and profile attractive in appearance.
Step 3 comprises: use turnbuckle to position, then based on automatic welding car, manual welding is that auxiliary welding manner welds.While carrying out step 3 welding, remove gap by the mode of Puttying, joint filling or polishing.This kind of welding manner, first in the process of welding, effectively can control the distortion of frame, improve the production efficiency of frame greatly, secondly only use manual welding than simple or only use robot welding more reasonably can arrange the direction of welding sequence and weld seam, ensure that the flatness and good looking appearance of having welded afer bay entirety, thus indirectly improve the total quality of frame and saved cost.
Step 4 comprises: use planer-type milling machine to carry out surperficial fine grinding to the frame after welding; Frame is 1.6 through surperficial fine grinding rear surface roughness Ra, and surface planarity is less than or equal to 0.5.The distortion that the friction produce in running the injection moulding apparatus be arranged on above frame and vibrations cause can play certain abirritation.Thus indirectly can increase the service life of product, improve the competitiveness of product.
The invention provides a kind of processing method being applicable to injection molding machine frame, the frame flatness utilizing this to produce and positional precision high, thus improve the kinematic accuracy of injection machine moving component.
More than show and describe general principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
