Description

Technical Field

[0001] The utility model belongs to the technical field of tractor seat leather processing, and particularly relates to a punching device for tractor seat leather processing. Background Art

[0002] Tractor seat leather usually refers to special leather or artificial leather used for manufacturing the surface material of tractor cab seats. When processing tractor seat leather, punching is required to endow the leather with specific breathability, weight reduction effect, and precise assembly with the seat frame, thereby improving the riding comfort and overall structural stability.

[0003] The existing punching devices for tractor seat leather processing usually use a vertical stamping method to perform punching operations on tractor seat leather. Although the punching operations on tractor seat leather can be achieved, there are still some problems in daily use. During the working process of traditional vertical stamping equipment, after the punching die executes a downward punching action, it needs to retract and reset, and then the leather workpiece is translated horizontally to make the next punching section enter the stamping area. This results in obvious intermittency in the leather punching operation and cannot achieve continuous and efficient punching operations, significantly reducing the overall production rhythm and production capacity. Secondly, when the traditional device responds to diverse punching patterns, hole diameter size adjustments, and different-density punching layouts, the die replacement is cumbersome and the parameter adjustment ability is limited, and it is often difficult to quickly respond to various complex punching requirements. Finally, during continuous punching operations on tractor seat leather, due to the lack of effective support for the leather, especially during large-area and high-density punching, the leather is prone to phenomena such as distortion and slippage due to uneven local stress, resulting in a decrease in the accuracy of the hole positions. Summary of the Utility Model

[0004] In view of this, the utility model provides a punching device for tractor seat leather processing, which can realize the rapid and continuous punching of multiple hole positions on tractor seat leather through a punching mechanism, improve the overall production rhythm and production capacity, meet the requirements of different-density punching of tractor seat leather, not only improve the flexibility of the punching device for tractor seat leather processing during use, but also ensure the accurate realization of various complex punching patterns, comprehensively meet the changing processing requirements of tractor seat leather, avoid the displacement of tractor seat leather caused by the pulling during punching by the punching knife, and ensure the quality of tractor seat leather during large-area and high-density punching operations.

[0005] To solve the above technical problems, the present utility model provides a punching device for processing tractor seat leather, which includes a workbench and a punching mechanism arranged at the upper end of the workbench. The punching mechanism includes a mounting plate arranged at the upper end of the left surface of the workbench. A sliding block is vertically slidably connected in a chute arranged in the middle of the upper end of the mounting plate. A rotating cylinder is rotatably connected in a rotating hole arranged in the middle of the sliding block. The outer arc surface of the rotating cylinder is provided with evenly distributed annular sockets. An activity plate is movably inserted into the socket at the uppermost end of the rotating cylinder. The upper surface of the activity plate is provided with evenly distributed transverse punching knives. An arc-shaped plate is movably inserted into a slot arranged in the middle of the upper surface of the workbench. The upper end of the outer arc surface of the arc-shaped plate is provided with avoidance holes corresponding to the punching knives one by one. A waste ejecting mechanism is arranged in each punching knife. The right end of the rotating cylinder is also provided with a locking component for limiting the activity plate. The upper right end of the workbench is also provided with a limiting component for fixing the arc-shaped plate. The upper surface of the workbench is provided with longitudinally symmetrically arranged downward pressing components.

[0006] The punching mechanism further includes a motor arranged on the left surface of the sliding block. The right end of the output shaft of the motor is fixedly connected to the left end of the rotating cylinder. The motor is electrically connected to an external single-chip microcomputer; the punching mechanism further includes an adjusting screw rod rotatably connected to the upper surface of the sliding block. A threaded hole adapted to the adjusting screw rod is arranged at the upper end of the mounting plate.

[0007] The waste ejecting mechanism includes ejecting heads respectively slidably connected in the punching knives. Springs are arranged between the lower end surfaces of the ejecting heads and the bottom wall surfaces of the punching knives where they are located.

[0008] The locking component includes a fixing plate arranged on the right side of the lower surface of the activity plate. A locking bolt is movably inserted into a circular hole arranged at the lower end of the fixing plate. Threaded holes are evenly distributed annularly at the edge of the right end surface of the rotating cylinder. The left end of the locking bolt is threadedly connected to the longitudinally adjacent threaded hole.

[0009] The limiting component includes a limiting plate arranged on the right surface of the arc-shaped plate. Limiting bolts are movably inserted into the longitudinally symmetrically arranged front and rear openings of the limiting plate. Limiting threaded holes corresponding to the limiting bolts one by one are arranged at the front and rear ends of the middle part of the right surface of the workbench.

[0010] The downward pressing components include fixing frames longitudinally symmetrically arranged on the upper surface of the workbench. Electric telescopic rods are arranged in the assembly openings arranged in the middle of the fixing frames. The lower ends of the telescopic ends of the electric telescopic rods are respectively provided with U-shaped plates. Pressing rollers are rotatably connected to the lower ends of the inner cavities of the U-shaped plates. The electric telescopic rods are all electrically connected to an external single-chip microcomputer.

[0011] The beneficial effects of the above technical solutions of the present utility model are as follows:

[0012] 1. First, the relevant staff place the tractor seat leather to be punched in the processing area formed between the rotating cylinder and the arc plate. Then, connect the end of the tractor seat leather to an external rewinder. After that, the relevant staff use an external single-chip microcomputer to control the coordinated operation of the motor and the external rewinder. The external rewinder evenly and synchronously pulls the tractor seat leather to move. At the same time, the output shaft of the motor rotates to drive the rotation of the rotating cylinder and its attached mechanisms. When the rotating cylinder rotates to a suitable position, the punching knife will align with the avoidance holes on the arc plate, thus realizing the rapid and continuous punching of multiple holes on the tractor seat leather, improving the overall production rhythm and production capacity.

[0013] 2. When switching different punching patterns or hole diameters, the relevant staff loosen the locking bolts and limit bolts accordingly, then take out the movable plate and the arc plate, and then select the movable plate and the arc plate that match the new punching requirements for replacement and installation to ensure that the equipment quickly adapts to the new processing requirements. At the same time, according to the punching density of the tractor seat leather, an appropriate number of movable plates can be selectively installed to meet the requirements of different density punching of the tractor seat leather, which not only improves the flexibility of the punching device for processing tractor seat leather during use, but also ensures the accurate realization of various complex punching modes and fully meets the changing processing requirements of the tractor seat leather.

[0014] 3. The relevant staff use an external single-chip microcomputer to control the operation of the electric telescopic rod. The telescopic end of the electric telescopic rod moves downward to drive the inverted U-shaped plate and the lower pressure roller to move downward synchronously, thereby limiting the tractor seat leather and preventing the tractor seat leather from shifting due to the pulling force generated during punching by the punching knife, ensuring the quality of the tractor seat leather during large-area and high-density punching operations.

[0015] 4. During the punching process, the top head is stressed and retracts into the punching knife against the elastic force of the spring. After punching is completed, the spring immediately pushes the top head under the action of its resilience force to push the waste material out of the punching knife, thus achieving the purpose of automatic unloading.

[0016] 5. When encountering tractor seat leather of different thicknesses, the relevant staff rotate the adjusting screw rod. The adjusting screw rod is screwed into the threaded hole, thereby adjusting the height of the sliding block and the entire punching mechanism to adapt to tractor seat leather of different thicknesses and ensuring accurate punching of leather of various thicknesses.

An active plate 204 is movably inserted into the socket 203 at the uppermost end of the rotating cylinder 202. The upper surface of the active plate 204 is provided with uniformly distributed punching knives 205 in a horizontal direction. An arc-shaped plate 206 is movably inserted into a slot arranged in the middle of the upper surface of the workbench 100. The upper end of the outer arc surface of the arc-shaped plate 206 is provided with avoidance holes 207 corresponding to the punching knives 205 one by one. A waste ejecting mechanism is arranged in each punching knife 205. The right end of the rotating cylinder 202 is further provided with a locking component for limiting the active plate 204. The upper right end of the workbench 100 is further provided with a limiting component for fixing the arc-shaped plate 206. The upper surface of the workbench 100 is provided with a pressing component symmetrically arranged longitudinally; The punching mechanism further includes a motor 208 arranged on the left surface of the sliding block 201. The right end of the output shaft of the motor 208 is fixedly connected to the left end of the rotating cylinder 202. The motor 208 is electrically connected to an external single-chip microcomputer; The punching mechanism further includes an adjusting screw rod 209 rotatably connected to the upper surface of the sliding block 201. The upper end of the mounting plate 200 is provided with a threaded hole adapted to the adjusting screw rod 209.

[0025] As Figures 1-4 shown, the locking component includes a fixing plate 400 arranged on the right side of the lower surface of the active plate 204. A locking bolt 401 is movably inserted into a circular hole arranged at the lower end of the fixing plate 400. The edge of the right end surface of the rotating cylinder 202 is provided with uniformly distributed threaded holes 402 in a ring shape. The left end of the locking bolt 401 is threadedly connected to the longitudinally adjacent threaded hole 402.

[0026] As Figures 1-4 shown, the limiting component includes a limiting plate 500 arranged on the right surface of the arc-shaped plate 206. Limiting bolts 501 are movably inserted into the openings symmetrically arranged longitudinally in the front and back of the limiting plate 500. The front and back ends of the middle part of the right surface of the workbench 100 are both provided with limiting threaded holes corresponding to the limiting bolts 501 one by one.

[0027] As Figures 1-3 shown, the waste ejecting mechanism includes ejecting heads 300 respectively slidably connected in the punching knives 205. Springs 301 are arranged between the lower end surfaces of the ejecting heads 300 and the bottom wall surfaces of the punching knives 205 where they are located.

[0028] The working principle of a punching device for processing tractor seat leather provided by the utility model is as follows: First, relevant staff place the tractor seat leather to be punched in the processing area formed between the rotating cylinder 202 and the arc-shaped plate 206. Then, connect the end of the tractor seat leather to an external winding machine. After that, relevant staff regulate the coordinated operation of the motor 208 and the external winding machine through an external single-chip microcomputer. The external winding machine uniformly and steadily pulls the tractor seat leather to move, and at the same time, the output shaft of the motor 208 rotates to drive the rotating cylinder 202 and its affiliated mechanisms to rotate. When the rotating cylinder 202 rotates to a suitable position, the punching knife 205 will align with the avoidance hole 207 on the arc-shaped plate 206, thereby realizing the rapid and continuous punching of multiple holes on the tractor seat leather, improving the overall production rhythm and production capacity. During the punching process, the top head 300 will be stressed and retract into the punching knife 205 against the elastic force of the spring 301. After punching is completed, the spring 301 immediately pushes the top head 300 under the action of its resilience force to push the waste material out of the punching knife 205, thereby realizing the purpose of automatic unloading. When encountering tractor seat leather with different thicknesses, relevant staff rotate the adjusting screw rod 209, and the adjusting screw rod 209 is screwed with the threaded hole, thereby adjusting the height of the sliding block 201 and the entire punching mechanism, so as to adapt to tractor seat leather with different thicknesses and ensure accurate punching of leather with various thicknesses. When switching different punching patterns or hole diameters, relevant staff loosen the locking bolt 401 and the limit bolt 501 in turn, then take out the movable plate 204 and the arc-shaped plate 206, and then select the movable plate 204 and the arc-shaped plate 206 that match the new punching requirements for replacement and installation, ensuring that the equipment quickly adapts to the new processing requirements. At the same time, the appropriate number of movable plates 204 can be selectively installed according to the punching density of the tractor seat leather, meeting the requirements of different density punching of the tractor seat leather, not only improving the flexibility of the punching device for processing tractor seat leather during use, but also ensuring the accurate realization of various complex punching modes and comprehensively meeting the changing processing requirements of the tractor seat leather.

[0029] As Figures 1-4 shown, the pressing component includes fixed frames 600 symmetrically arranged longitudinally on the upper surface of the workbench 100. Electric telescopic rods 601 are arranged in the assembly ports in the middle of the fixed frames 600. The lower ends of the telescopic ends of the electric telescopic rods 601 are both provided with U-shaped plates 602. The lower ends of the inner cavities of the U-shaped plates 602 are both rotatably connected with pressing rollers 603. The electric telescopic rods 601 are all electrically connected to an external single-chip microcomputer. During this process, relevant staff regulate the operation of the electric telescopic rods 601 through an external single-chip microcomputer. The telescopic ends of the electric telescopic rods 601 move downward to drive the U-shaped plates 602 and the pressing rollers 603 at the lower ends to move downward synchronously, thereby limiting the tractor seat leather and preventing the tractor seat leather from shifting due to the pulling force generated during punching by the punching knife 205, ensuring the quality of the tractor seat leather during large-area and high-density punching operations.

For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
