Problems solved by technology

[0002] The tripod workpiece is a component that is often used in the furniture production process, and the elbow of the tripod workpiece needs to be punched on the upper and lower arc-shaped side walls on both sides of the elbow during the processing process. The traditional punching process is Before the elbow is welded for the connectors, the elbow is punched. After punching the arc surface on one side of the elbow with a punching tool, turn the elbow over and punch the arc surface on the other side. Punching, but because the shape of the elbow is U-shaped, this processing method is not easy to locate the elbow, the work efficiency is low, and the punching of the upper and lower arc surfaces is inconsistent, which is prone to errors
[0003] In the Chinese patent with the patent number CN106181267A, a production process of an automobile exhaust pipe that is formed first and then punched is disclosed. Positioning punching, but the shape of the exhaust pipe is regular, easy to position punching, so this production process cannot be adapted to the punching process of irregular pipes

Embodiment 1

[0039] Such as figure 2 and image 3 As shown, a tripod workpiece includes:

[0040] An elbow 11, the two sides of the elbow 11 are bent symmetrically;

[0041] The connecting piece 12 is symmetrically arranged on the upper arc surface of the elbow 11 and is fixedly connected with the elbow 11 by welding.

[0042] It should be noted that the number of connectors 12 is not limited to the two mentioned in this embodiment, and can be changed according to actual production conditions.

[0043] It is further explained that, because the elbow 11 is U-shaped, its shape is not easy to locate. Therefore, by adjusting the order of the processing steps of the tripod workpiece 1, the welding process steps of the elbow 11 and the connecting piece 12 are advanced to the time when the elbow 11 punches. Before the hole processing step, use the elbow 11 and the connecting piece 12 to weld the tripod workpiece 1, and then use the connecting piece 12 as the positioning coordinates to punch t...

Embodiment 2

[0066] Figure 4 It is a structural representation of a tripod workpiece punching die of the present invention; as Figure 4 As shown, the parts that are the same as or corresponding to those in Embodiment 1 use the reference numerals corresponding to Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below. This embodiment two and figure 1 The difference of the shown embodiment one is:

[0067] Such as Figure 4 , Figure 5 and Figure 6 Shown, a kind of tripod workpiece punching die comprises:

[0068] The upper mold assembly 2, the upper mold assembly 2 includes an upper mold base 21, the front end of the upper mold base 21 is symmetrically provided with a first positioning groove 211, and the lower end of the upper mold base 21 is connected with an upper splint 22; The two sides of the upper splint 22 are provided with second positioning grooves 221 corresponding to the positions of the first positioning grooves 211, an...

Embodiment approach

[0089] Such as Figure 10 and Figure 11 As shown, as a preferred embodiment, the lower mold assembly 3 also includes:

[0090] Lower mold base 33, described lower mold base 33 is positioned at the below of described lower mold bottom plate 31, and it is fixedly connected with this lower mold bottom plate 31;

[0091] A shaft sleeve 34, the shaft sleeve 34 is symmetrically arranged on both sides of the rear end of the bottom mold bottom plate 31, which is arranged corresponding to the guide shaft 24;

[0092] A plurality of lower optical axes 35, the lower optical axes 35 are arranged at the four corners of the bottom plate 31 of the lower mold;

[0093] The lower floating block 36, the lower floating block 36 is symmetrically arranged on both sides above the bottom plate 31 of the lower mold, and the lower floating block 36 slides vertically along the lower optical axis 35, and the middle part of the lower end is provided with a lower clip The holding bayonet 361, the lowe...

Abstract

The invention discloses a punching machining technology of a bent pipe foot stand workpiece. The punching machining technology comprises the first step of a primary locating procedure, the second step of a secondary locating procedure, the third step of an upper punching procedure and the fourth step of a lower punching procedure. The machining technology of the foot stand workpiece is changed, the machining manner of previously directly carrying out punching on a bent pipe is changed, the bent pipe and connecting parts are welded to form the foot stand workpiece, and then the foot stand workpiece is applied to cooperation of a punching mold and the connecting parts on a foot stand; the technical problem about punching precise locating of the foot stand workpiece is solved; and then by means of mold compounding between an upper mold assembly and a lower mold assembly, the two arc side faces of the foot stand workpiece are perforated synchronously, the punching precision of the foot stand workpiece is guaranteed, and the work efficiency is improved.
