Problems solved by technology

[0006] Aiming at the problems that the existing punching device for sheet metal parts does not have a wide application range, the force of the punched parts is uneven, the edge to be cut is easily damaged, and high-quality and high-efficiency punching cannot be realized, the present invention provides a lifting type sheet metal punching device. Piece punching device, which adds a telescopic piston to realize the lifting of the whole punching tool, adopts the guide sleeve with balls to cooperate with the guide column, so that the sliding of the guide sleeve is more continuous, smooth and stable, and the tapered cutout can be used. achieve high quality

Embodiment 1

[0027] Such as figure 1 , figure 2 as well as image 3 As shown, a lift-type sheet metal punching device includes a base plate 1, a punch 8 and a die 9, and also includes a telescopic looper 2, a cylinder 3, a guide rod 5, a guide sleeve 6, and a punch seat 7, and the cylinder 3 is located on the top plate 4, the piston of the cylinder 3 is connected to the middle part of the punch seat 7; the telescopic looper 2 and the guide rod 5 are fixed on the side of the bottom plate 1 away from the feed port; the top of the telescopic looper 2 is fixed on the top plate 4 the lower surface; the guide rod 5 passes through the top plate 4 and is fixed with a nut; the guide sleeve 6 is set on the guide rod 5 and is connected with the two ends of the punch seat 7; the guide sleeve 6 is also provided with a ball 601; the punch 8 is fixed on Below the punch seat 7, and the shape of the lower end surface is conical.

[0028] In addition, there are two telescopic loopers 2, which are distri...

Embodiment 2

[0031] Same as embodiment 1, the difference is that the taper angle of the tapered portion of the lower end surface of the punch 8 is 40°, which reduces the contact area and better realizes punching under the premise of ensuring that the die is not damaged.

Embodiment 3

[0033] Same as embodiment 1, the difference is that there are 4 guide rods to ensure more stable and reliable work of the punching tool and to obtain better quality sheet metal parts.

Abstract

The invention belongs to the technical field of sheet metal parts processing equipment, and in particular relates to a lifting type sheet metal part punching device. It includes a telescopic looper, a cylinder, a guide rod, a guide sleeve and a punch seat. The cylinder is located on the top plate, and the piston of the cylinder is connected to the middle part of the punch seat; the telescopic looper and the guide rod are all fixed on the bottom plate on the side away from the feed inlet; the top of the telescopic looper is fixed on the lower surface of the top plate; the guide rod passes through the top plate and is fixed with nuts; The two ends are connected; the guide sleeve is also provided with balls; the punch is fixed under the punch seat, and the shape of the lower end surface is tapered. The invention adds telescoping pistons to realize the lifting of the whole punching tool, adopts the guide sleeve with balls to cooperate with the guide column, makes the sliding of the guide sleeve more continuous, smooth and stable, and adopts tapered cutouts to achieve high quality. High efficiency cutting.

Description

technical field [0001] The invention belongs to the technical field of sheet metal parts processing equipment, and in particular relates to a lifting type sheet metal part punching device. Background technique [0002] Sheet metal parts are products processed by sheet metal technology. They have the characteristics of light weight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, and good mass production performance. Instruments and other fields have been widely used. For example, in computer cases, mobile phones, and MP3 players, sheet metal parts are an indispensable part. Sheet metal parts are fabricated by filament power winding, laser cutting, heavy machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending, die forging, water jet cutting, precision welding . Among them, the cutting of sheet metal parts is especially common. [0003] In the prior art, a cylinder is often u...
