Description

Technical Field

[0001] This utility model relates to the field of mechanical processing technology, and in particular to a stamping and blanking structure for a refrigerator bottom steel plate. Background Technology

[0002] As the core load-bearing and protective component of a refrigerator, the bottom steel plate requires multiple processes such as stamping and bending to be manufactured. The precision of stamping directly affects the assembly compatibility and structural stability of the bottom steel plate. With the increasing demands for lightweight and high-precision products in the home appliance industry, the stamping process of the refrigerator bottom steel plate faces even greater technical challenges.

[0003] Currently, most mainstream refrigerator bottom steel plate stamping and blanking equipment on the market adopts the traditional stamping machine structure, which still has the following two shortcomings in practical applications:

[0004] First, the guiding and limiting effect of the lifting mechanism is not good during the stamping process. The lifting plate is prone to left and right swaying, which leads to a decrease in the contact accuracy between the stamping cutting edge and the steel plate. This not only affects the dimensional tolerance of the bottom steel plate, but may also cause accelerated wear of the cutting edge and reduce the service life of the equipment.

[0005] Secondly, stamping operations generate a large amount of metal shavings. These shavings fly at high speeds, which can easily cause safety hazards such as scratches and crushing injuries to operators. Although some protective measures are set up, in actual operation, some workers ignore these protective measures in order to save time, which poses a risk of work-related injuries. Utility Model Content

[0006] This utility model relates to a stamping and blanking structure for the bottom steel plate of a refrigerator, which solves the problems of poor guiding and limiting effect of the lifting mechanism during the stamping process, easy left and right swaying of the lifting plate, and the generation of a large amount of metal shavings during the stamping operation, which can easily cause scratches to the operator by high-speed flying of these shavings.

[0007] This utility model provides a refrigerator bottom steel plate stamping and blanking structure, specifically including: an operating table;

[0008] Four support rods are fixedly installed on the upper surface of the operating table. Two sets of threaded holes are opened on the upper surface of the operating table. A module is provided on the upper surface of the operating table. The module is connected to the operating table by bolts. Two connecting blocks are installed on the front surface of the operating table. A control switch is installed on the upper surface of the connecting blocks.

[0009] The cover plate is a rectangular plate structure. The cover plate is fixedly installed on the upper end face of four support rods. An electric cylinder is installed on the upper end face of the cover plate.

[0010] The lifting plate has two sets of threaded holes on its lower end surface. An impact block is installed in the middle of the lower end surface of the lifting plate. The impact block is connected to the lifting plate by bolts. The upper end surface of the lifting plate is fixedly connected to the end surface of the telescopic part of the electric cylinder.

[0011] The lower connecting plate is fixedly connected to the connecting block at its upper end, and a fixing block is welded to the inner end face of the lower connecting plate.

[0012] The protective net has an external frame structure and an internal cross-shaped structure. Two limiting rods are installed on the lower end face of the protective net, and baffles are fixedly installed on the end face of the limiting rods.

[0013] Furthermore, two ear plates are symmetrically installed on the outer end face of the lifting plate, and through-holes are opened on the surface of the ear plates. The support rod is engaged in the limiting holes on the surface of the ear plates.

[0014] Furthermore, a limiting cylinder is installed inside the fixing block, and a magnetic ring is installed inside the limiting cylinder.

[0015] Furthermore, the limiting rod is slidably fitted inside the limiting cylinder, and the outer end face of the limiting rod is in contact with the inner end face of the magnet ring.

[0016] Furthermore, a protective cover is installed on the left and right ends of the upper surface of the protective net, and a groove is provided on the lower surface of the protective cover.

[0017] Furthermore, when the lower end face of the protective cover is in contact with the upper end face of the connecting block, the control switch at the upper end of the connecting block is engaged in the groove on the lower end surface of the protective cover.

[0018] This utility model provides a stamping and blanking structure for the bottom steel plate of a refrigerator, which has the following beneficial effects:

[0019] 1. Four support rods are installed on the upper surface of the operating table. The four support rods are vertically fixed to the upper surface of the operating table. Two ear plates are installed on the left and right ends of the lifting plate. The four support rods are engaged in the limiting holes on the surface of the ear plates, so that the support rods can play a limiting role when the lifting plate moves up and down, so as to prevent the lifting plate from swaying left and right when moving up and down, and to avoid the deviation affecting the stamping effect.

[0020] 2. The protective net is slidably mounted in the limiting cylinder of the fixed block by the limiting rod at the lower end. The outer end face of the limiting rod is in contact with the magnetic ring inside the limiting cylinder. The magnetic force is used to position the protective net. During the stamping operation, the protective net can be lifted up so that the protective net is in front of the operating table, which serves to protect the workers.

[0021] 3. Two protective covers are installed on the upper surface of the safety net. The lower surface of the protective covers has a groove. When the safety net is moved to the bottom, the lower surface of the protective cover fits against the upper surface of the connecting block. At this time, the control switch on the upper end of the connecting block will be engaged in the groove at the lower end of the protective cover, making it easy for workers to remove the stamped parts and replace the parts to be stamped. When the worker needs to press the control switch again to start the electric cylinder, the worker must lift the safety net upwards to expose the two control switches. In other words, the worker cannot start the electric cylinder when the safety net is not lifted. This plays a role in forced protection, preventing some workers from ignoring the protective measures in order to save time and minimizing the possibility of workplace injuries.

Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Example 1: Please refer to Figures 1 to 6 :

[0035] This utility model proposes a stamping and blanking structure for the bottom steel plate of a refrigerator, including: an operating table 1;

[0036] Four support rods 101 are fixedly installed on the upper end face of the control panel 1. Two sets of threaded holes are opened on the upper end face of the control panel 1. A module is provided on the upper end face of the control panel 1. The module is connected to the control panel 1 by bolts. Two connecting blocks 102 are installed on the front end face of the control panel 1. A control switch 1021 is installed on the upper end face of the connecting block 102.

[0037] Cover plate 2, the main body of cover plate 2 is a rectangular plate structure, cover plate 2 is fixedly installed on the upper end face of four support rods 101, and electric cylinder 3 is installed on the upper end face of cover plate 2;

[0038] The lifting plate 4 has two sets of threaded holes on its lower surface. An impact block is installed in the middle of the lower surface of the lifting plate 4. The impact block is connected to the lifting plate 4 by bolts. The upper surface of the lifting plate 4 is fixedly connected to the end surface of the telescopic part of the electric cylinder 3.

[0039] The lower connecting plate 5 is fixedly connected to the connecting block 102 at its upper end, and a fixing block 6 is welded to the inner end face of the lower connecting plate 5.

[0040] The protective net 7 has an external frame structure and an internal cross-shaped structure. Two limiting rods 701 are installed on the lower end face of the protective net 7. A baffle 7011 is fixedly installed on the end face of the limiting rod 701, and the baffle 7011 plays a limiting role.

[0041] Two ear plates 401 are symmetrically installed on the outer end face of the lifting plate 4. The surface of the ear plate 401 is provided with a through-hole limiting hole 4011. The support rod 101 is engaged in the limiting hole 4011 on the surface of the ear plate 401. In use, two ear plates 401 are installed on the left and right ends of the lifting plate 4 respectively, and four support rods 101 are engaged in the limiting hole 4011 on the surface of the ear plate 401. This allows the support rods 101 to play a limiting role when the lifting plate 4 moves up and down, so as to prevent the lifting plate 4 from swaying left and right when moving up and down, and to avoid the deviation affecting the stamping effect.

[0042] The fixed block 6 has a limiting cylinder 601 installed inside, and a magnetic ring 6011 is installed inside the limiting cylinder 601. The limiting rod 701 is slidably locked inside the limiting cylinder 601, and the outer end face of the limiting rod 701 is in contact with the inner end face of the magnetic ring 6011. In use, the protective net 7 is slidably locked inside the limiting cylinder 601 of the fixed block 6 by the lower limiting rod 701. The outer end face of the limiting rod 701 is in contact with the magnetic ring 6011 inside the limiting cylinder 601. The positioning of the protective net 7 can be achieved by using magnetic force.

[0043] The protective net 7 has a protective cover 8 installed on each of its upper left and right ends. The lower end of the protective cover 8 has a groove 801. When the lower end of the protective cover 8 is in contact with the upper end of the connecting block 102, the control switch 1021 on the upper end of the connecting block 102 is engaged in the groove 801 on the lower end of the protective cover 8. In use, when the worker needs to press the control switch 1021 again to start the electric cylinder 3, the worker must lift the protective net 7 upwards to expose the two control switches 1021. In other words, the worker cannot start the electric cylinder 3 when the protective net 7 is not lifted. This provides forced protection and prevents some workers from ignoring protective measures in order to save time, thus minimizing the possibility of workplace injuries.

[0044] The working principle of this embodiment:

[0045] In this invention, four support rods 101 are installed on the upper surface of the operating table 1. The four support rods 101 are vertically fixed to the upper surface of the operating table 1. Two ear plates 401 are installed on the left and right ends of the lifting plate 4 respectively. The four support rods 101 are engaged in the limiting holes 4011 on the surface of the ear plates 401, so that the support rods 101 can play a limiting role when the lifting plate 4 moves up and down, so as to prevent the lifting plate 4 from swaying left and right when moving up and down, and to avoid the deviation affecting the stamping effect when stamping the bottom steel plate of the refrigerator. The steel plate can be placed on the upper surface of the operating table 1, and then the electric cylinder 3 is activated. The telescopic part of the electric cylinder 3 extends downward, driving the lifting plate 4 to move vertically downward along the support rod 101 to complete one stamping operation. When stamping the steel plate, some debris will fly outward. This flying debris can cause injury to the worker if it hits him. The protective net 7 is slidably locked into the limiting cylinder 601 of the fixed block 6 by the lower limiting rod 701. The outer end face of the limiting rod 701 is in contact with the magnetic ring 6011 inside the limiting cylinder 601. The protective net 7 is positioned using magnetic force. During the stamping operation, the protective net 7 can be lifted upwards, positioning it directly in front of the operating table 1 to protect the worker. After the impact is complete, the worker presses the protective net 7 downwards, causing it to move downwards. Two protective covers 8 are installed on the upper surface of the protective net 7, and the lower surface of the protective covers 8 has a groove 801. When the protective net 7 moves to its lowest point, the lower surface of the protective cover 8 fits against the upper surface of the connecting block 102. At this time, the control switch 10 on the upper end of the connecting block 102 is activated. 21 will be snapped into the groove 801 at the lower end of the protective cover 8, making it easy for workers to remove the stamped parts and replace the parts to be stamped. When the worker needs to press the control switch 1021 again to start the electric cylinder 3, the worker must lift the protective net 7 to expose the two control switches 1021. In other words, the worker cannot start the electric cylinder 3 when the protective net 7 is not lifted. This plays a role in forced protection, preventing some workers from ignoring protective measures in order to save time and minimizing the possibility of workplace injuries.
