Description

Technical Field

[0001] This utility model relates to the field of punch press technology, and in particular to a punch press fixing mechanism for processing air conditioner radiators. Background Technology

[0002] Air conditioning radiators are an indispensable part of air conditioning systems. They are mainly responsible for effectively dissipating the heat generated by the air conditioning unit or compressor, ensuring the normal operation of the air conditioning system. During the operation of the air conditioning, the radiator can absorb and dissipate the heat generated by components such as the compressor and condenser, preventing the air conditioning system from overheating, thereby protecting the normal operation of the electronic components and refrigerant inside the system. The punch press fixing mechanism is an important part of the punch press equipment used to fix the workpiece and ensure that it remains stable during the punching process. The structural design of this fixing mechanism is designed to provide sufficient clamping force and stability to adapt to the characteristics of the workpiece material and the requirements of the punching process.

[0003] To address this, Chinese patent application CN216575209U discloses a punch press clamping mechanism, including a mounting plate. An adjusting screw is rotatably connected to one side of the mounting plate. A first movable plate and a second movable plate are threadedly connected to the outer surface of the adjusting screw. A support plate is fixedly connected to the top of both the first and second movable plates. A positioning plate is movably connected to one side of each support plate. Buffer mechanisms are provided at the four corners of the bottom of the mounting plate. The advantages of this invention are: by setting the positioning plate, the mold can be clamped and positioned, effectively increasing the stability of the device during processing. It is also suitable for molds of various sizes, effectively increasing ease of use. The buffer mechanisms provide a certain buffering capacity to the mounting plate during processing, thus preventing wear on the worktable caused by prolonged punching.

[0004] While the current punch press fixing mechanism can basically meet people's needs, some problems still exist, as detailed below:

[0005] 1. The problem of the punch press fixing mechanism being unable to fix the workpiece to be processed: During the stamping process, the workpiece is subjected to the joint extrusion of the upper and lower dies, which makes it easy for it to shift and deviate during the processing. The fixing and clamping mechanism cannot fix the workpiece to be processed, making it difficult to ensure the stability of the workpiece during the processing, which will affect the processing accuracy.

[0006] 2. The problem of the punch press fixing mechanism failing to protect workers: When stamping a workpiece, the upper die will move down and work together with the lower die to process the workpiece. If the worker's hand is not removed in time during the stamping process, it will be injured. The fixing and clamping mechanism cannot remind or protect workers during the processing, which can easily lead to safety hazards. Utility Model Content

[0007] The purpose of this utility model is to provide a punch press fixing mechanism for processing air conditioner radiators, so as to solve the defects of existing punch press fixing mechanisms that are difficult to fix the workpiece to be processed and difficult to protect the workers.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a punch press fixing mechanism for processing air conditioner radiators, including a worktable;

[0009] A back plate is integrally formed at one end of the top of the workbench, and a top plate is integrally formed at the top of the back plate. A cylinder is installed inside the top plate.

[0010] A lifting plate is fixed to the bottom of the cylinder, an upper mold is installed at the bottom of the lifting plate, side plates are installed on both sides of the bottom of the top plate, and a lower mold is installed at the top of the worktable.

[0011] The top of the workbench is equipped with fixing structures on both sides, the top of the top plate is equipped with a guide structure, and one end of the lifting plate is equipped with a protective structure.

[0012] In use, the workpiece to be processed is first placed on the lower mold. The cylinder is then activated to make the lifting plate and the upper mold descend synchronously. The upper and lower molds are used to press the workpiece. During the descent of the lifting plate, the push block follows and pushes the clamping plate to clamp and fix the workpiece. At the same time, the first mounting seat installed on the lifting plate also descends, driving the first connecting rod and the second connecting rod to rotate. When it descends to the lowest point, the baffle will rotate to one end of the lower mold to block the workpiece and prevent the worker's hand from being injured if it is not removed in time.

[0013] Furthermore, the fixing structure includes a support member, a clamping plate, a moving rod, a fixed plate, a spring, and a push block. The support member is fixed to both sides of the top of the worktable, and a clamping plate is installed on the top of the support member. A moving rod is fixed to one side of the clamping plate. The fixed plate is fixed to both sides of the top of the worktable, and a spring is installed on the outside of one side of the moving rod to clamp and fix the workpiece and prevent the workpiece from shifting during processing.

[0014] Furthermore, the spring is elastic, and the spring and the moving rod are elastically connected. The spring returns to its original shape, thereby driving the moving rod and the clamping plate back to their original positions, thus ending the clamping of the workpiece.

[0015] Furthermore, the push blocks are fixed on both sides of the bottom end of the lifting plate, and the push blocks are symmetrically distributed on both sides of the bottom end of the lifting plate, so that the clamping plates on both sides can be pushed simultaneously for clamping.

[0016] Furthermore, the guiding structure includes a guide roller, a positioning rod, a guide groove, and a positioning block. The guide roller is fixed on both sides of the top of the top plate, the positioning rod is fixed on both sides of the top of the lifting plate, the guide groove is fixed on one side of the side plate, and the positioning block is fixed on one side of the push block, which can improve the stamping stability between the upper and lower dies.

[0017] Furthermore, a slide rail is provided on one side of the guide groove, and a slider is provided on one side of the positioning block. The guide groove and the positioning block are slidably connected, which can guide the descent of the lifting plate and the upper mold.

[0018] Furthermore, the protective structure includes a first mounting base, a second mounting base, a first connecting rod, a second connecting rod, and a baffle. The first mounting base is fixed to both sides of one end of the lifting plate, and the second mounting base is fixed to one end of the side plate. A first connecting rod is hinged to one side of the first mounting base, and a second connecting rod is hinged to one side of the second mounting base. A baffle is fixed to the bottom end of the second connecting rod, which can block the upper and lower dies that are working during the stamping process, preventing the worker's hands from being left unattended in time.

[0019] The present invention provides a punch press fixing mechanism for processing air conditioner radiators, which has the following advantages: This punch press fixing mechanism for processing air conditioner radiators, through its fixing structure, can clamp and fix the workpiece to be processed while the cylinder drives the lifting plate and upper die to descend for punching, preventing the workpiece from shifting. Since the fixing structure is synchronized with the punching operation, no additional operation is required, saving time and effort. The guide structure at the top of the top plate can guide the descent of the upper die, improving the processing accuracy. The protective structure installed on one end of the lifting plate and side plate also proceeds synchronously with the punching, protecting the worker during the punching process.

[0020] By symmetrically installing two sets of push blocks at the bottom of the lifting plate, during stamping, the push blocks will descend together with the lifting plate under the drive of the cylinder to push the clamping plate, so that the clamping plates on both sides can simultaneously clamp and fix the workpiece. When the processing is completed, the push blocks will move up and return to their original position, and the spring will return to its original state, thereby driving the moving rod and the clamping plate back to their original position, thus ending the clamping of the workpiece. This achieves the purpose of the punch press fixing mechanism to fix the workpiece to be processed.

[0021] By installing a first mounting seat at one end of the lifting plate, the first mounting seat will descend with the lifting plate when the workpiece is being stamped. The first connecting rod will rotate through the hinge, pushing the second connecting rod outward towards the worker, thereby moving the baffle towards the worker and blocking the upper and lower dies that are being stamped. After the stamping is completed, the first mounting seat will rise with the lifting plate, pulling the second connecting rod upward to prevent the baffle from blocking the lower die. This achieves the purpose of protecting the worker through the fixed mechanism of the punch press. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5 One embodiment of this utility model is a punching machine fixing mechanism for processing air conditioner radiators, which includes a worktable 1.

[0030] The top of the workbench 1 has a back plate 2 integrally formed at one end, and the top of the back plate 2 has a top plate 3 integrally formed at the top. The top plate 3 has a cylinder 4 installed inside.

[0031] A lifting plate 5 is fixed to the bottom of the cylinder 4, and an upper mold 6 is installed at the bottom of the lifting plate 5. Side plates 7 are installed on both sides of the bottom of the top plate 3, and a lower mold 8 is installed at the top of the worktable 1.

[0032] Fixed structures 9 are installed on both sides of the top of the workbench 1. The fixed structures 9 include support members 901, clamping plates 902, moving rods 903, fixing plates 904, springs 905, and push blocks 906. Support members 901 are fixed on both sides of the top of the workbench 1. Clamping plates 902 are installed on the top of the support members 901. Moving rods 903 are fixed on one side of clamping plates 902. Fixing plates 904 are fixed on both sides of the top of the workbench 1. Springs 905 are installed on the outside of one side of moving rods 903. Springs 905 are elastic and are elastically connected to moving rods 903. Push blocks 906 are fixed on both sides of the bottom of the lifting plate 5. Push blocks 906 are symmetrically distributed on both sides of the bottom of the lifting plate 5.

[0033] See attached document Figure 1-4 As shown, two sets of push blocks 906 are symmetrically installed at the bottom of the lifting plate 5. During stamping, the push blocks 906 will descend together with the lifting plate 5 under the drive of the cylinder 4. During the descent, they will push the clamping plate 902, so that the clamping plates 902 on both sides move towards the middle at the same time and clamp and fix the workpiece, so as to prevent the workpiece from shifting during the processing. During the movement of the clamping plate 902, it will drive the moving rod 903 to move synchronously. Since one side of the spring 905 is installed on the fixed plate 904 and the other side is fixed to one side of the moving rod 903, when the moving rod 903 moves, it will squeeze the spring 905. When the processing is completed, the push block 906 moves up and returns to its original position, the spring 905 will return to its original state, thereby driving the moving rod 903 and the clamping plate 902 back to their original positions, thus ending the clamping of the workpiece and making it easy to pick up the workpiece.

[0034] A guide structure 10 is installed at the top of the top plate 3. The guide structure 10 includes a guide roller 1001, a positioning rod 1002, a guide groove 1003, and a positioning block 1004. The guide roller 1001 is fixed on both sides of the top of the top plate 3, the positioning rod 1002 is fixed on both sides of the top of the lifting plate 5, the guide groove 1003 is fixed on one side of the side plate 7, and the positioning block 1004 is fixed on one side of the push block 906. A slide rail is provided on one side of the guide groove 1003, and a slider is provided on one side of the positioning block 1004. The guide groove 1003 and the positioning block 1004 are slidably connected.

[0035] See attached document Figure 1-4As shown, first mounting bases 1101 are fixed on both sides of the top of the top plate 3. When the lifting plate 5 rises and falls, the positioning rod 1002 moves accordingly. The sliding of the positioning rod 1002 in the guide roller 1001 can guide the descent of the lifting plate 5 and the upper mold 6. At the same time, the positioning block 1004 fixed on one side of the push block 906 will also slide along the slide groove set on the guide groove 1003 to avoid deviation during descent. This can improve the stability of stamping between the upper mold 6 and the lower mold 8 and help improve the processing accuracy.

[0036] A protective structure 11 is installed at one end of the lifting plate 5. The protective structure 11 includes a first mounting base 1101, a second mounting base 1102, a first connecting rod 1103, a second connecting rod 1104, and a baffle 1105. The first mounting base 1101 is fixed to both sides of one end of the lifting plate 5, and the second mounting base 1102 is fixed to one end of the side plate 7. The first connecting rod 1103 is hinged to one side of the first mounting base 1101, and the second connecting rod 1104 is hinged to one side of the second mounting base 1102. The baffle 1105 is fixed to the bottom end of the second connecting rod 1104.

[0037] See attached document Figure 1-2 and attached Figure 4-5 As shown, a first mounting base 1101 is installed at one end of the lifting plate 5. When the workpiece is being stamped, the first mounting base 1101 will descend with the lifting plate 5. The first connecting rod 1103 will rotate through the hinge, and the first connecting rod 1103 will become horizontal, pushing the second connecting rod 1104 outward towards the worker, thereby moving the baffle 1105 towards the worker and blocking the upper mold 6 and lower mold 8 that are being stamped. This prevents the worker's hands from being squeezed and injured by the upper mold 6 and lower mold 8 if they are not removed in time, thus protecting the worker's safety. After the stamping is completed, the first mounting base 1101 will rise with the lifting plate 5, and the first connecting rod 1103 will rotate to become vertical, pulling the second connecting rod 1104 upward, so that the second connecting rod 1104 and the baffle 1105 become approximately horizontal, preventing the baffle 1105 from obstructing the lower mold 8, making it easier for the worker to pick up the workpiece and place a new workpiece to be processed.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
