[0002] Punch press refers to a stamping press. In my country's industrial production, the stamping process is more and more widely used because it saves materials and energy, is highly efficient, has low technical requirements for operators, and can produce products that cannot be achieved by mechanical processing through various mold applications.

[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in the technology: one of the most important structures on the punch press is the guide rail. When the guide rail works for a long time, heat will accumulate on it, so it needs to be cooled. However, the cooling structure of the current punch press guide rail is usually fixed to the guide rail body as one, which makes it inconvenient to disassemble and assemble, and thus inconvenient for subsequent maintenance or replacement.

[0004] To this end, we propose a cooling structure for a punch press to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a cooling structure for a punching machine. By contracting a plurality of electric telescopic rods on two positioning seats and moving a plurality of clamping seats away from a slideway, the plurality of clamping seats on both sides of a coolant pipe can be released from fixing the coolant pipe, so that the coolant pipe can be conveniently removed for maintenance or replacement, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A cooling structure for a punch press comprises a punch press guide rail, a slideway is arranged on the punch press guide rail, a coolant pipe is arranged on the side of the punch press guide rail facing away from the slideway and is fitted with the punch press guide rail, two protruding seats are symmetrically welded on the side of the punch press guide rail facing away from the slideway, servo motors are mounted on the two protruding seats, movable grooves are formed on the two protruding seats facing each other, the output shafts of the two servo motors are coaxially connected with screw rods, the servo motors need to be powered by external power facilities, inner movable blocks are respectively threadedly sleeved on the two screw rods, and the two inner movable blocks are respectively fitted with the inner walls of the two movable grooves;

[0008] Positioning seats are welded on the opposite sides of the two inner movable blocks, and multiple connecting blocks are welded on both sides of each positioning seat. Electric telescopic rods are installed on the multiple connecting blocks. A clamping seat is connected to the telescopic end of each electric telescopic rod. There are multiple clamping seats and they are symmetrically distributed on both sides of the punch guide rail. The clamping seat is U-shaped and the coolant pipe is crimped and fixed, so that the coolant pipe fits on the punch guide rail to absorb heat.

[0009] As a preferred embodiment, side grooves are formed on the opposite sides of the two protruding seats, and the two servo motors are respectively installed on the inner walls of the two side grooves, so that the structures of the two servo motors remain stable.

[0010] As a preferred embodiment, the two screws are rotatably connected to the inner walls of the two movable grooves respectively, and the two screws are coaxially designed, so that the two screws can operate stably.

[0011] As a preferred implementation scheme, the opposite sides of the two inner movable blocks extend into the two movable grooves respectively, so that the two inner movable blocks can only be extended and retracted in one direction without shaking.

[0012] As a preferred embodiment, a bottom groove is formed on one side of each connecting block facing the punch guide rail, and the electric telescopic rod on the connecting block is installed on the inner wall of the bottom groove, so that the electric telescopic rod structure remains stable.

[0013] In summary, the technical effects and advantages of the utility model are as follows:

[0014] The cooling structure for a punch press can release the fixing of the multiple clamping seats on both sides of the coolant pipe by retracting the multiple electric telescopic rods on the two positioning seats to move the multiple clamping seats away from the slideway, so that the coolant pipe can be easily removed for maintenance or replacement.

[0015] The cooling structure for the punch press can also drive two servo motors to drive two screws to operate if the position of the clamping seat is inaccurate, so that the two inner movable blocks can translate in the two movable grooves, thereby driving the two positioning seats and the clamping seats thereon to translate, thereby fine-tuning the position of the clamping seat to make its position accurate.

[0026] Active grooves 6 are formed on the opposite sides of the two protruding seats 3, and the output shafts of the two servo motors 5 are coaxially connected with screw rods 7, which are rotatably connected to the inner walls of the two active grooves 6, and the two screw rods 7 are coaxially designed so that the two screw rods 7 can operate stably. The servo motor 5 needs to be powered by external power facilities. Internal active blocks 8 are respectively threadedly sleeved on the two screw rods 7, and the two internal active blocks 8 are respectively fitted with the inner walls of the two active grooves 6, and the opposite sides of the two internal active blocks 8 are respectively extended into the two active grooves 6, so that the two internal active blocks 8 can only be extended and retracted in one direction without shaking.

[0027] Positioning seats 9 are welded on the opposite sides of the two inner movable blocks 8, and multiple connecting blocks 10 are welded on both sides of each positioning seat 9, and electric telescopic rods 12 are installed on the multiple connecting blocks 10. A bottom groove 11 is formed on the side of each connecting block 10 facing the punch guide rail 1. The electric telescopic rod 12 on the connecting block 10 is installed on the inner wall of the bottom groove 11, so that the structure of the electric telescopic rod 12 remains stable.
