Description

Technical Field

[0001] The utility model belongs to the technical field of corner plate stamping, in particular to a corner plate continuous stamping blanking device. Background Art

[0002] In the prior art, after searching, it was found that a Chinese patent disclosed "a continuous stamping and blanking sorting device for angle plates for drawers", and its application number is "CN202220061607.0". This patent mainly sets a stamping material introduction structure and a protective pad introduction structure, which work alternately during use to introduce stamping parts and protective pads into the storage box, ensuring that a protective pad is introduced immediately after each stamping part is input, so that two adjacent stamping parts are separated by the protective pad, which can effectively reduce the damage caused by mutual expansion between the stamping parts during the blanking and sorting process.

[0003] However, in the process of corner plate stamping, a punch head is usually used to directly stamp the corner plate. When the impact force of the punch head is too large, it may cause the corner plate to be displaced or unevenly stressed, and the thickness of the corner plate part is uneven, thus affecting the appearance quality and precision of the product. Utility Model Content

[0004] The purpose of the utility model is to provide a continuous stamping and blanking device for corner plates. By providing a stamping mechanism, the pressure exerted by the pressure plate on the corner plate can be relieved, so as to avoid damage to the corner plate due to excessive force during the stamping process. The problem that excessive impact force of the punching head may cause displacement of the corner plate or uneven force on the corner plate, and uneven thickness of the corner plate part, thereby affecting the appearance quality and precision of the product is solved.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a continuous punching and unloading device for angle plates, comprising a fixed frame, a connecting disc and an angle plate, wherein the fixed frame comprises a punching mechanism, a driving mechanism, a limiting mechanism, a connecting mechanism and a discharging mechanism;

[0007] The stamping mechanism includes a plurality of sliding rods passing through the connecting disc, the sliding rods are slidably connected to the connecting disc, a pressure plate is fixedly installed at the bottom ends of the plurality of sliding rods, a spring is sleeved on the plurality of sliding rods, the top ends of the plurality of springs are fixedly connected to the bottom surface of the connecting disc, if the bottom ends of the springs are fixedly connected to the top surface of the pressure plate, a stamping head is fixedly installed on the bottom surface of the connecting disc, the stamping head passes through the pressure plate, and the bottom end of the stamping head extends to the bottom surface of the pressure plate.

[0008] Furthermore, the driving mechanism comprises a hydraulic cylinder fixedly mounted on the top surface of the fixed frame, the output end of the hydraulic cylinder is fixedly connected to a hydraulic rod, and the bottom end of the hydraulic rod is fixedly connected to the top surface of the connecting disc.

[0009] Furthermore, the limiting mechanism includes a fixed seat fixedly mounted on the inner bottom wall of the fixed frame, the top surface of the fixed seat is provided with a T-shaped groove, the inner wall of the T-shaped groove is slidably connected with a T-shaped slider, the back of the T-shaped slider is fixedly mounted with a push rod, and the end of the push rod is fixedly mounted with a push block.

[0010] Furthermore, the connection mechanism comprises a connection rod hinged on the top surface of the T-shaped slider, a connection block is fixedly mounted on the connection disc, and one end of the connection rod away from the T-shaped slider is hinged to the connection block.

[0011] Furthermore, the discharging mechanism includes a corner plate assembly and a discharging assembly, the corner plate assembly includes a support seat fixedly mounted on the inner bottom wall of the fixed frame, the support seat is provided with a groove, the inner wall of the groove is slidably connected with a corner plate, and the back side of the top block is in contact with the corner plate.

[0012] Furthermore, the discharge assembly includes a slope fixedly installed inside the support seat, and a stamping hole is opened on the top surface of the support seat.

[0013] The utility model has the following beneficial effects:

[0014] 1. By setting up a stamping mechanism, the spring and the sliding rod cooperate with each other. When the connecting disc moves downward, the bottom surface of the pressure plate contacts the top surface of the angle plate, and the spring is compressed, which can relieve the pressure applied by the pressure plate to the angle plate, avoiding damage to the angle plate due to excessive force during the stamping process. After the pressure plate contacts the angle plate, the connecting disc continues to move downward, so that the stamping head can stamp the angle plate, thereby achieving the purpose of the stamping head stamping the angle plate to form a product.

[0015] 2. By setting up a connecting mechanism, the connecting rod and the connecting block cooperate with each other. When the hydraulic cylinder drives the connecting disc to move downward to punch the diagonal plate, it can drive the top block to move forward, and the top block is away from the pressure plate. After the diagonal plate is stamped, the hydraulic cylinder drives the connecting disc to move upward. At this time, the connecting rod drives the top block to move backward, so that the top block can push the corner plate out, realizing the automatic unloading function after the stamping is completed, reducing the operation of manual unloading, and greatly improving the efficiency of stamping. At this time, the diagonal plate can also be continuously stamped by adjusting the output rate of the hydraulic cylinder, thereby improving the flexibility of the device.
