Abstract
The invention relates to a manufacturing method for frame products, which is characterized in that: a cold rolled sheet is made into a flattened shape of frame; the length of the flattened shape of frame is the perimeter of the frame; a dovetail groove with broken error is arranged on each node of the frame through a punching die; a convex dovetail groove and a concave dovetail groove the shape of both are coincided with each other are respectively arranged on the interface; the flattened shape of frame is made to bend in the horizontal direction and into L shape along the bending line of the frame; the nodes of the frame are made to bend for a quad frame formed; then the dovetail groove with broken error is pressed into the concave dovetail groove which is coincided with the dovetail groove, thereby the structure is made stable and the frame is manufactured. The invention has the advantages that the lower of the waste of raw materials can be maximized and the utilization rate of raw materials can be increased.
Description
Technical field
The present invention relates to a kind of manufacture method of shell frame products, relate in particular to the manufacture method that the framework manufacture method that has drawing and forming of a complexity is converted into frame-generic, belong to the manufacture method technical field of shell frame products.
Background technology
At present, the complicated framework manufacture method that has drawing and forming is to make a rectangle sealing part earlier, then central big square hole is washed out, words in this way, raw-material utilization rate probably has only 1/3, waste to material is very serious, and need do special-purpose Drawing Die and make this product.
Summary of the invention
The purpose of this invention is to provide a kind of manufacture method of saving the shell frame products of material.
For realizing above purpose, technical scheme of the present invention provides a kind of manufacture method of shell frame products, it is characterized in that, directly makes the leg of frame, folding then forming, and its method is:
The first step. adopt cold-reduced sheet to make framework and flatten profile, the length of its profile is the girth of framework, be manufactured with the dovetail groove of offset with diel on each node of framework, make protruding dovetail groove and recessed dovetail groove in the port respectively, protruding dovetail groove matches with the shape of recessed dovetail groove;
Second step. framework is flattened profile carry out horizontal bending, be converted into the L type along the bending line of framework;
The 3rd step. the node place at framework carries out bending, and protruding dovetail groove is compressed into recessed dovetail groove, makes it into a quadrilateral frame;
The 4th step. the dovetail groove of accomplishing fluently offset is compressed into the recessed dovetail groove that cooperates with it, make it Stability Analysis of Structures, framework is made.
Distance between described per two nodes is the length of framework and wide.
The present invention directly makes the leg of frame, and four angle one sides of the leg of frame are separated, and its raw material area is 0.105m
2The area that it launches has only about 1/3 of original material, improved the utilization rate of material widely, as long as just can reach this effect by simple bending several times, in order to make this framework more firm, with instrument the offset of being up to is originally returned again, the stability of framework just can not be affected like this.
Advantage of the present invention is to reduce raw-material waste substantially, increases raw-material utilization rate.
Description of drawings
Fig. 1 is the framework expanded view;
Fig. 2 is the oat tail groove structure figure that offset is arranged;
Fig. 3 is the framework schematic diagram;
Fig. 4 is the structural representation at four angles of framework.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, be the framework expanded view, a kind of manufacture method of shell frame products is:
The first step. adopt cold-reduced sheet to make framework and flatten profile 1, the length of its profile is the girth of framework, as shown in Figure 1, on each node 2 of framework, be manufactured with the dovetail groove 3 of offset with diel, as shown in Figure 2, distance between per two nodes 2 is the length of framework and wide, makes protruding dovetail groove 4 and recessed dovetail groove 5 respectively in the port, and protruding dovetail groove 4 matches with the shape of recessed dovetail groove 5;
Second step. framework is flattened profile 1 carry out horizontal bending, be converted into the L type along the bending line 6 of framework;
The 3rd step. node 2 places at framework carry out bending, and protruding dovetail groove 4 is compressed into recessed dovetail groove 5, make it into a quadrilateral frame, as shown in Figure 3;
The 4th step. the dovetail groove 3 of accomplishing fluently offset is compressed into the recessed dovetail groove that cooperates with it, as shown in Figure 4, make it Stability Analysis of Structures, framework is made.
The present invention saves raw material especially, saves cost of manufacture, is a kind of very economical, very efficient a kind of method to like product, is worth recommending.
