Problems solved by technology

[0004] When the existing tubular workpiece is processed, it is fixed by the positioning mechanism and then punched directly through the punching machine. In the existing stamping method, the same tube needs to be processed twice in order to be better welded to another tubular workpiece. , resulting in low processing efficiency

Embodiment 1

[0028] Embodiment one: a kind of punch die for processing tubular workpiece, such as figure 1 As shown, it includes a base 1 , a positioning mechanism 2 installed on the base 1 , and a stamping mechanism 5 installed on the base 1 .

[0029] Such as figure 1 As shown, a slide groove 3 is provided on the base 1 along the length direction of the base 1 , and a slide groove 4 communicating with the slide groove 3 is provided on the upper end of the base 1 .

[0030] Such as figure 1 As shown, the stamping mechanism 5 includes two groups of stamping blocks 6 slidably connected in the chute 3, a return spring 8 arranged between the stamping blocks 6 and one end side wall of the chute 3, and a convenient set is provided at the upper ends of the two groups of stamping blocks 6. The V-shaped opening 7 stamped by the punch press is provided with an adjustment mechanism 9 for adjusting the compression amount of the return spring 8 between the return spring 8 and the side wall at one en...

Embodiment 2

[0041] Embodiment two: the difference between embodiment two and embodiment one is: as figure 2 As shown, the positioning member 18 includes a rotating rod 23 rotatably connected to the base 1, a mounting rod 24 fixedly connected to the surface of the rotating rod 23, and a positioning ring with different diameters installed on the end of the mounting rod 24 away from the rotating rod 23. 22, the distance from the center of each positioning ring 22 to the axis of the mounting rod 24 is the same.

[0042] Working principle: Step 1: Select positioning rings 22 with different diameters according to the size of the pipeline to be processed;

[0043] Step 2: Fix the positioning ring 22 through the fixing block 21 by adjusting the fixing bolt 20;

[0044] The third step: according to different pipes to be processed, replace punches 10 of different sizes;

[0045] Step 4: Turn the driving handle 15, adjust the position of the baffle plate 13, and adjust the position of the return ...

Abstract

The invention discloses a punching machine die used for machining pipe-shaped workpieces. The punching machine die comprises a base and a positioning mechanism installed on the base. A sliding grooveis formed in the base in the length direction of the base, a slide groove is formed in the upper end of the base, and the sliding groove communicates with the slide groove; a punching mechanism is installed on the base and comprises two punching blocks connected into the sliding groove in a sliding manner, the upper ends of the punching blocks are provided with openings facilitating punching by apunching machine, and reset springs are arranged between the punching blocks and the side wall of one end of the sliding groove; and adjusting mechanisms used for adjusting the amount of compression of the reset springs are arranged between the reset springs and the side wall of one end of the sliding groove; and the two punching blocks are driven by the openings by means of the punching machine to move to the two edges, meanwhile, the pipe-shaped workpieces are punched, the reset springs are compressed through the punching blocks, according to the punching manner, the two edges of the pipe-shaped workpieces are punched, the punching efficiency is improved, the time interval between two times of punching is shortened, and the punching efficiency is further improved.

Description

technical field [0001] The invention relates to a punch die, in particular to a punch die for processing tubular workpieces. Background technique [0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Known as the "Mother of Industry". [0003] A mold is a tool that makes a blank into a workpiece with a specific shape and size under the action of external force. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plasti...
