Description

Technical Field

[0001] The invention relates to the technical field of punching machine, in particular to a punching machine with multi-station progressive die linkage. Background Art

[0002] The multi-station progressive die linkage punch press machine is a kind of equipment used in stamping production. It combines the functions of multi-station progressive die and punch press to achieve efficient and continuous stamping processing.

[0003] When the existing multi-station progressive die linkage punching machine is in use, it is usually stamped synchronously with the same pressure, which makes it difficult to apply different pressures according to the thickness difference of different materials, increasing the risk of deformation and cracks or rebound phenomena, resulting in a high frequency of downtime for maintenance; when the existing technology is in use, it is difficult to change the shape of the punch head to achieve different stamping effects, resulting in poor product quality, and at the same time causing high wear of the material, short service life, and increased material waste; In addition: the existing technology is difficult to spray material layers on the punch head according to the number of stamping times, resulting in poor coating utilization efficiency, increased coating waste, shortened punch head life, and prone to punch head size deviation due to wear, and the new punch head surface may have micro-unevenness or burrs. The existing technology is difficult to preheat the new punch head, and it is easy for metal debris or lubricant residue to stick together due to temperature difference when in contact with the material, resulting in dimensional deviation or scratches on the first few pieces of material due to uneven contact, and repeated impacts of the cold new punch head under high pressure are prone to fatigue failure, resulting in higher peak stress in the initial stage of stamping; when the existing technology is in use, it is difficult to predict the remaining life of the punch head and automatically trigger shutdown, and it is difficult for some equipment to stabilize the clock signal, reduce jitter and enhance heat dissipation efficiency during use, and the practicality is relatively simple; Finally: It is difficult to feed materials synchronously with the existing technology. After feeding, it is difficult to detect whether the center is aligned, which can easily lead to deviations in the stamping process and affect the yield of the material. Summary of the invention

A mounting mechanism 38 is provided at the bottom of the first fixed plate 37, and three groups of cylinders 39 are fixedly connected to the top of the first mounting box 31, and the cylinders 39 are convenient for driving the first connecting seat 310 to move.

[0026] The push rod at the bottom of the cylinder 39 passes through the top of the first installation box 31 and is fixedly connected to the top of the first connecting seat 310. The first connecting seat 310 is rotatably connected to the outer wall of the friction block 311. The right end of the top of the first connecting seat 310 is fixedly connected to an electric spring 312, and the electric spring 312 is electrically connected to an external power supply.

[0027] A resistance strain gauge 313 is glued and connected to the spring wire axis in the ±45° direction of the electric spring 312, a spray mechanism 314 is fixedly connected to the bottom rear end of the first installation box 31, and a control mechanism 315 is fixedly connected to the left side of the front end of the first installation box 31.

[0029] The working principle of a multi-station progressive die linkage punching machine based on the first embodiment is: First, when using this device, first place the device in the working area, and then connect the device to an external power source to provide the device with the power required for operation; Second, the staff draws washable center lines on multiple groups of materials in advance, places three groups of materials to be stamped on the feeding mechanism 4 through an external manipulator, and synchronously conveys the three groups of materials through the feeding mechanism 4, so that the three groups of materials are conveyed to the bottom of the punching head 381, and then starts the first motor 32, the first motor 32 drives the conveyor belt 33 to drive, so that the three groups of pulleys in the conveyor belt 33 drive the three groups of first turntables 34 to rotate through the wheel rod, the three groups of first turntables 34 drive the three groups of first convex rods 35 to make circular motions, the three groups of first convex rods 35 drive the three groups of first slide plates 36 to move downward, the three groups of first slide plates 36 drive the three groups of first fixed plates 37 to move downward, and the three groups of first fixed plates 37 drive the three groups of mounting mechanisms 38 to move downward, so that the three groups of materials of the punching head 381 are stamped in the three groups of mounting mechanisms 38; Third, during the stamping process, the staff places corresponding gram weights at the empty slots on the left and right ends of the top of the first fixed plate 37. According to the calculation formula of the stamping force F=ma (where F is the stamping force, m is the mass of the stamping head 381, and a is the acceleration of the stamping head 381), when the mass of the stamping head 381 increases due to the increase of the weights, under the same acceleration, the stamping force of the stamping head 381 increases, and then the cylinder 39 is started, and the cylinder 39 drives the first connecting seat 310 to move downward, and the first connecting seat 310 drives the friction block 311 to move downward, so that the friction block 311 contacts the first turntable 34, and the electric spring 312 is powered by an external power supply. The electric spring 312 stretches with the movement of the first connecting seat 310 and generates a stress field around it. This stress field will affect the resistance strain gauge 313. Resistance value, and then the resistance strain element inside the resistance strain gauge 313 is deformed by the stress, so that the user can calculate the length change of the electric spring 312 through the resistance value of the resistance strain gauge 313, and indirectly calculate the moving distance of the first connecting seat 310 through the length change of the electric spring 312, thereby calculating the moving distance of the friction block 311. When the moving distance of the friction block 311 increases, the positive pressure increases, the friction force increases accordingly, and the descending speed of the punch head 381 decreases. Conversely, when the moving distance of the friction block 311 decreases, the positive pressure decreases, the friction force decreases accordingly, and the descending speed of the punch head 381 increases, thereby re-adjusting the punching force of the punch head 381, and then applying different pressures according to the thickness differences in different materials, reducing the risk of deformation and cracks or rebound phenomena, and preventing a high frequency of downtime for maintenance.
