CN202062448U - Tension clamp for producing ultrathin plastic filter screen used on blue-printing machine - Google Patents

Abstract

The utility model improves a tensioning fixture used for producing ultra-thin plastic filter screens for printing machines, and is characterized in that it includes a fixing frame and pressing blocks located at both ends of the fixing frame, and the fixing frame and the pressing blocks are connected by screws . The tensioning fixture of the utility model compresses and fixes the ultra-thin plastic plate on the fixing frame, reduces the possibility of damaging the plate during punching, and improves the success rate of punching. At the same time, a spacer is provided between the pressing block and the fixing frame to prevent damage to the board due to over-tightening, thereby protecting the ultra-thin plastic board. In addition, because the sliding screw can slide along the chute, it can clamp plates of different widths, and it can meet more needs with different molds. The opening provided by the fixing frame can facilitate the free sliding of the ultra-thin plastic sheet during the punching process. The tensioning fixture of the utility model has low cost, can greatly improve the yield of the filter screen used in the printing machine, and has strong practicability.

Description

Tensioning fixture for the production of ultra-thin plastic filters for printing machines

technical field

The utility model belongs to the field of processing parts of a printing machine, in particular to a tensioning fixture used for producing an ultra-thin plastic filter screen for a printing machine.

Background technique

When producing filter screens for printing machines, it is necessary to move the raw material sheet to carry out the punching process on the sheet. However, in the prior art, the impact force of punching often causes the ultra-thin plastic sheet to slide, resulting in chaotic distribution of small holes on the ultra-thin plastic sheet, and the subsequent punching cannot meet the needs of the filter screen for the printing machine, wasting materials. Increased costs.

Contents of the invention

The purpose of this utility model is to provide a tension fixture for producing ultra-thin plastic filter screens for printing machines according to the above-mentioned deficiencies in the prior art, which can prevent the ultra-thin plastic sheet from sliding due to the impact force of punching, thereby saving cost.

The utility model is realized through the following technical scheme: it comprises a fixing frame and pressing blocks located at both ends of the fixing frame, and the fixing frame and the pressing blocks are connected by screws.

One end of the fixed frame is provided with a chute, and a slidable sliding screw is provided in the chute, and the other end of the fixed frame is provided with a through hole and a fixed screw that cooperates with it; the sliding screw and the fixed screw will press The block is pressed tightly with the fixing frame.

A gasket is also provided between the pressing block and the fixing frame.

One end of the fixing bracket is open.

The tensioning fixture of the utility model compresses and fixes the ultra-thin plastic plate on the fixing frame, reduces the possibility of damaging the plate during punching, and improves the success rate of punching. Simultaneously, a spacer is arranged between the pressing block and the fixing frame, which can prevent the board from being damaged by too tight fixing, thereby protecting the board. In addition, because the sliding screw can slide along the chute, it can clamp plates of different widths, and it can meet more needs with different molds. The opening provided by the fixing frame can facilitate the free sliding of the ultra-thin plastic sheet during the punching process. The tensioning fixture of the utility model has low cost, can greatly improve the yield of the filter screen used in the printing machine, and has strong practicability.

Detailed ways

Further illustrate the utility model below in conjunction with accompanying drawing:

As shown in Figures 1-4, the tensioning fixture of the present utility model includes two opposite fixing frames 2 and four pressure blocks 4 located at the four corners of the fixing frames 2, and one end of each fixing frame 2 is provided with a chute 3. A slidable sliding screw 9 and a nut 10 are provided in the chute 3, and the other end of each fixing frame 2 is provided with a through hole 8 and a fixed screw 12 and a nut 10 matched therewith; The sliding screw 9 and the fixing screw 12 compress the briquetting block 4 and the fixed frame 2 tightly. A gasket 11 is also provided between the pressing block 4 and the fixing frame 2 . When in use, first fix the fixed frame 2 on the CNC feeding frame through the fixture fixing hole 1, then use the pressing block 4 to fix and clamp the plate 7 on the fixed frame 2, and then fix the punching die 6 on the punching machine through the punch connecting hole 5 , that is, the plate 7 can be continuously punched.

The utility model reduces the possibility of damage to the plate during punching by tensioning and fixing the plate 7, improves the success rate of punching, and has strong practicability.
