Description

Technical Field

[0001] The utility model relates to the technical field of stamping workbenches, in particular to a stamping table which is convenient for loading materials. Background Art

[0002] A stamping die is a special technical facility that processes materials into parts during cold stamping. It is called a cold stamping die. The die can realize rapid batch production of workpieces and is an indispensable equipment in industrial production. However, in the actual application of a continuous stamping workbench, when the punch head contacts the material, a controller is required to stop the transport mechanism and then start it after the stamping is completed. This not only requires an additional controller for control, but also requires the drive to work and stop repeatedly, which seriously affects the working life of the drive and is not conducive to practical application. Utility Model Content

[0003] The purpose of the utility model is to provide a punching table which is convenient for loading materials, so as to overcome the above-mentioned defects in the prior art.

[0004] According to the utility model, a stamping table for convenient loading includes a lower mold, two guide slides distributed inside and outside are fixedly provided at the left and right ends of the lower mold, and fixed frames and fixed plates distributed inside and outside are fixedly provided at the ends of the left and right guide slides far away from each other, the fixed frames and the fixed plates are fixedly connected by fixed rods, a transport chain is provided on the outer periphery of the fixed plate, a rotating wheel controlled by a power source is provided at the fixed plate, and abuts against the fixed plate to drive the transport chain to move, a stamping rod is connected to the upper end of the lower mold, and the stamping rod is controlled by a gas rod, and the lower end of the stamping rod is fixedly connected to an upper mold head and an extension plate, and the two guide slides distributed inside and outside are slidably connected with guide slides, which are mutually The two adjacent guide sliding rods are provided with a clamping mechanism at the ends close to each other, and the ends away from each other are splined with a spline rod. The clamping mechanism includes a fixed plate connected to the guide sliding rod, an electromagnetic plate connected to the fixed plate, and a clamping plate connected to the electromagnetic plate. The two spline rods at the ends away from each other are fixed with a chuck. A spring is connected between the guide sliding rod and the spline rod. The chuck can engage with the transport chain. The lower end of the extension plate is fixed with two left and right symmetrical push plates. The lower ends of the two push plates are inclined and can abut against the ends away from each other of the two adjacent chucks on the left and right. The ends away from each other of the left and right groups of guide sliding frames are fixed with contact sensors that can abut against the chuck.

[0005] The beneficial effects of the utility model are:

[0006] The push plate abuts against the chuck, so that the chuck picks up and engages with the transport chain, thereby preventing the plate from moving during transportation. The push plate abuts against the chuck to support the clamping mechanism, increasing the stability of the clamping mechanism when clamping the plate, facilitating the stamping work. There is no need to use an additional controller to control the start and stop of the transport chain and the movement of the clamping mechanism, which is convenient and practical.

[0015] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there can be an intermediate element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element at the same time: Example

[0017] Reference Figure 1-Figure 6 According to an embodiment of the utility model, a punching table for convenient loading includes a lower mold 10, two guide slides 19 distributed inside and outside are fixedly provided at the left and right ends of the lower mold 10, and the ends away from each other on the left and right guide slides 19 are fixedly provided with fixed frames 17 and fixed plates 22 distributed inside and outside, and the fixed frames 17 and the fixed plates 22 are fixedly connected by fixed rods, and a transport chain 18 is provided on the outer periphery of the fixed plate 22, and a rotating wheel controlled by a power source is provided at the fixed plate 22 to abut against the fixed plate 22 to drive the transport chain 18 to move, and a punching rod 13 is connected to the upper end of the lower mold 10, and the punching rod 13 is controlled by a gas rod, and the lower end of the punching rod 13 is fixedly connected to the upper die head 12 and the extension plate 20, and the two guide slides 19 distributed inside and outside are slidably connected with guides Slide bar 15, two adjacent guide slide bars 15 are provided with clamping mechanism 14 at their mutually close ends, and spline rod 16 is splined to each other at their mutually distant ends, the clamping mechanism 14 comprises a fixed plate connected to the guide slide bar 15, an electromagnetic plate connected to the fixed plate, a clamping plate connected to the electromagnetic plate, chucks 24 are fixedly provided at mutually distant ends of the two spline rods 16, a spring is connected between the guide slide bar 15 and the spline rod 16, the chuck 24 can mesh with the transport chain 18, two left-right symmetrical push plates 21 are fixedly provided at the lower end of the extension plate 20, the lower ends of the two push plates 21 are tilted to abut against the mutually distant ends of the two adjacent left-right chucks 24, and contact sensors 23 are fixedly provided at mutually distant ends of the left and right two groups of guide slide frames 19 to abut against the chuck 24;

[0018] During operation, the left and right ends of the sheet 11 are clamped by the two adjacent clamping mechanisms 14 on the left and right to transport the sheet 11 to the bottom of the punching rod 13. The movement of the sheet 11 is achieved by the engagement between the chuck 24 and the transport chain 18. The movement of the transport chain 18 drives the meshing clamping mechanism 14 to move synchronously. The cylinder at the punching rod 13 works intermittently. The cylinder controls the punching rod 13 to perform a downward and then upward reciprocating motion at regular intervals. The upper die head 12 fixed at the lower end of the punching rod 13 abuts against the sheet 11 for punching work. In the meantime, during the downward movement of the punching rod 13, the push plates 21 at the left and right ends move downward synchronously through the extension plate 20 fixedly connected to the punching rod 13. Through the inclined surface at the lower end of the push plate 21, the push plate 21 pushes the left and right chucks 24 to overcome the spring force and approach each other. The chuck 24 shrinks into the guide slide rod 15, and the chuck 24 loses engagement with the transport chain 18, thereby stopping the movement process of the clamping mechanism 14 transporting the sheet 11. Figure 5 As shown, the chuck 24 abuts against the contact sensor 23 on the guide slide 19, and the contact sensor 23 is used to record the number of times and time the chuck 24 is bonded, so as to compare with the number of stamping times and time of the stamping rod 13, and then it can be judged whether the stamping work is carried out normally. A material transport path is provided at the lower end of the lower mold 10, and a plate 11 is provided on the material transport path. When the clamping mechanism 14 follows the movement of the transport chain 18 and slides downward to the lower end of the lower mold 10, the clamping mechanisms 14 at the left and right ends abut against the left and right ends of the plate 11, and the plate 11 is transported from the lower end of the lower mold 10 to the upper end of the lower mold 10. The clamping mechanism 14 is energized to make the electromagnetic plate generate magnetic force, which pushes the magnetic clamping plate to fit the plate 11, and clamps the left and right ends of the plate 11.
