Description

A punching template

technical field

The utility model relates to the field of punching and forming, in particular to a punching template with convenient maintenance.

Background technique

Existing stamping dies are generally divided into two parts, the upper die and the lower die, in which the upper die is basically fixedly connected by the die handle in the center of the die base and the slider of the punching machine to realize the stamping process; however, in actual stamping production, for large Due to its own weight, the mold cannot rely on the local clamping force of the mold handle to ensure the installation accuracy of the mold. At the same time, for multi-station continuous molds, due to the large number of stamping punches, especially for small punches with complex shapes and weak parts , often needs to be repaired and replaced. For this reason, we have developed a stamping template with simple structure and convenient maintenance, which shortens the mold development cycle and improves production efficiency. Die assembly accuracy.

Utility model content

The purpose of the utility model is to provide a stamping template with simple structure and convenient maintenance in order to overcome the deficiencies of the prior art, thereby shortening the mold development cycle and improving production efficiency, and the reliable connection between the upper mold part and the punching machine ensures The assembly accuracy of the punch.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a stamping template, including an upper mold base with grooves on both sides; Die; the punch is provided with a slot; the slot is provided with a washer fixed to the bottom of the upper mold base by screws.

Preferably, the upper end of the upper die base is respectively provided with a plurality of stepped holes; each of the large holes of the stepped holes is provided with a pad made of steel and flush with the upper end surface of the upper die base, and in the small hole A punch with clearance fit is provided.

Due to the application of the above-mentioned technical solution, the utility model has the following advantages compared with the prior art:

The stamping formwork described in the utility model has simple structure and convenient maintenance, thereby shortening the mold development cycle and improving production efficiency, and the upper mold part is reliably connected with the punch through the groove to ensure the assembly accuracy of the punch.

Description of drawings

Below in conjunction with accompanying drawing, technical scheme of the utility model is further described:

Accompanying drawing 1 is the sectional view of stamping template described in the utility model;

Among them: 1. Upper mold base; 11. Groove; 2. Block; 3. Punch; 4. Washer; 5. Screw; 6. Die.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

Accompanying drawing 1 is the stamping template described in the utility model, comprises the upper die base 1 that groove 11 is respectively arranged on both sides; The upper end both sides of described upper die base 1 is respectively provided with stepped holes; The big hole is provided with a pad 2 made of 45 steel and flush with the upper surface of the upper mold base 1. Since the mold base is generally made of gray cast iron, the strength of the mold base is improved through the pad 2, and the small hole is provided with a The punch 3 that fits through the clearance is easy to take out; the punch 3 is provided with a draw-in groove; the washer 4 fixed on the bottom of the upper mold base 1 by a screw 5 is arranged in the draw-in groove, which is convenient for disassembly; during work, the upper The die base 1 is fixed on the punch press by the briquetting block or the pressing plate on the punch press through the grooves 11 on both sides, and the punch 3 cooperates with the corresponding die 6 cutting edges in the lower die base to complete the stamping.

When the punch 3 needs to be disassembled, the screw 5 is unscrewed and the gasket 4 is taken out, and the punch 3 is pulled out from the upper die base 1, and then maintenance, replacement, etc. can be carried out.

Due to the application of the above-mentioned technical solution, the utility model has the following advantages compared with the prior art:

The stamping formwork described in the utility model has simple structure and convenient maintenance, thereby shortening the mold development cycle and improving production efficiency, and the upper mold part is reliably connected with the punch through the groove to ensure the assembly accuracy of the punch.

The above are only specific application examples of the utility model, and do not constitute any limitation to the protection scope of the utility model. All technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the utility model.
