Description

Technical Field

[0001] This utility model relates to the field of spring bending machine technology, and in particular to a spring pressing and bending device. Background Technology

[0002] Springs are widely used in various contact devices, and spring bending machines are an indispensable part of the metal processing industry. Their development is closely linked to technological progress, with continuously growing market demand and ongoing technological innovation driving industry development. (Reference) Figures 1 to 5 A contact device includes a base 1 and a spring 2. The base 1 has multiple mounting positions 3 for mounting the spring 2. The spring 2 has an L-shaped structure, and the mounting positions 3 have mounting holes 4. The connection between the spring 2 and the base 1 is as follows: the spring 2 is mounted on the mounting position 3, and one end of the spring 2 is installed in the mounting hole 4 and bent at a certain angle, thereby fixing the spring 2 to the base 1. Currently, the processing of contact devices is mostly done manually: first, the spring 2 is placed on the mounting position 3, then one end of the spring 2 is inserted into the mounting hole 4 on the base 1, and the operator presses the spring 2 by hand to make one end of the spring 2 fully inserted into the mounting hole 4. Then, a manual bending machine is used to bend the spring 2 mounted on the base 1 at a certain angle, thereby completing the processing of the contact device.

[0003] However, the method of manually riveting and bending the springs is inefficient, lacks precision, and is limited by the skill level of the workforce, making it impossible to meet the needs of large-scale production. Utility Model Content

[0004] The purpose of this utility model is to provide a spring clip riveting and bending device, which has the advantages of improving the automation level of the equipment, enabling it to complete the processing work quickly and accurately, and greatly improving production efficiency.

[0005] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0006] A spring clip pressing and bending device includes a frame;

[0007] The upper template is fixedly provided with an upper mold ejector pin, and the frame is provided with a first driving component for driving the upper template to slide vertically and reciprocally so that the upper mold ejector pin presses and rivets the spring piece into the mounting hole;

[0008] A transfer plate, which is located directly below the upper template and slidably connected to the frame, is provided with a fixing groove for a fixing base;

[0009] The lower template is located directly below the transfer plate and is fixedly installed on the frame. The lower template is fixedly provided with a lower mold ejector pin for bending the spring piece riveted into the mounting hole.

[0010] In one embodiment of this utility model, an elastic element is fixedly provided on the lower template, and the rebound force generated by the elastic element pushes the carrier plate upward to disengage the base from the lower mold ejector pin.

[0011] In one embodiment of the present invention, an auxiliary unloading assembly is provided on the transfer plate. The auxiliary unloading assembly includes a clamp fixing plate slidably connected to the transfer plate, a fixing clamp fixedly installed on the clamp fixing plate, and a second driving member disposed on the transfer plate and used to drive the clamp fixing plate to slide horizontally back and forth.

[0012] The fixing groove is provided on the fixing fixture.

[0013] In one embodiment of the present invention, a guide support frame is fixedly provided on the transfer plate, and a guide groove is provided on the guide support frame, and the clamp fixing plate is slidably connected in the guide groove.

[0014] In one embodiment of the present invention, a first limiting post is fixedly provided on the upper part of the transfer plate, and a second limiting post is fixedly provided on the bottom of the transfer plate.

[0015] In one embodiment of the present invention, the lower template is provided with a limiting hole that engages with the second limiting post.

[0016] In one embodiment of this utility model, a guide shaft is fixedly provided on the lower template, and linear bearings that are slidably connected to the guide shaft are provided on both the upper template and the transfer plate.

[0017] In one embodiment of this utility model, the upper end of the lower mold ejector pin is provided with an inclined surface.

[0018] As described above, the spring clip riveting and bending device of this utility model has the following beneficial effects:

[0019] 1. The first driving component drives the upper template to press down, which in turn drives the transfer plate to press down. The upper and lower templates then cooperate, causing the upper die ejector pin to press and rivet the spring sheet into the mounting hole. Simultaneously, the lower die ejector pin bends the spring sheet pressed into the mounting hole, thus achieving automated processing. Automated production ensures that the spring sheet is accurately pressed and riveted onto the base, precisely controlling parameters such as riveting depth and bending angle, ensuring that the processed product meets design requirements and satisfies customer precision needs. It enables fast and accurate completion of processing work, greatly improving production efficiency.

[0020] 2. The elastic force generated by the elastic element pushes the carrier plate upward to disengage the base from the lower mold ejector pin; after the base disengages from the lower mold ejector pin, the auxiliary feeding component is used to assist in feeding; the second driving component is used to push the fixture fixing plate out of the processing area, so that there is enough space to facilitate the subsequent removal of the contact device from the fixing groove.

[0034] Please see Figure 6 , Figure 9 and Figure 10 This utility model provides a spring sheet riveting and bending device, including a frame 5, an upper template 6, a transfer plate 9, and a lower template 11. An upper mold ejector pin 7 is fixedly mounted on the upper template 6. A first driving member 8 is provided on the frame 5 to drive the upper template 6 to slide vertically back and forth so that the upper mold ejector pin 7 rivets the spring sheet 2 into the mounting hole 4. The transfer plate 9 is located directly below the upper template 6 and is slidably connected to the frame 5. The transfer plate 9 is provided with a fixing groove 10 for fixing the base 1. The lower template 11 is located directly below the transfer plate 9 and is fixedly mounted on the frame 5. A lower mold ejector pin 12 is fixedly mounted on the lower template 11 to bend the spring sheet 2 riveted into the mounting hole 4. Multiple sets of corresponding upper mold ejector pins 7 and lower mold ejector pins 12 are provided on the upper template 6 and the lower template 11, and multiple sets of fixing grooves 10 corresponding to the upper mold ejector pins 7 and lower mold ejector pins are provided on the transfer plate 9. This allows the device to process multiple products at once, improving work efficiency.

[0035] Please see Figure 7 and Figure 8 The lower template 11 is fixedly mounted on the base plate of the frame 5 by bolts. Four guide shafts 23 are fixedly installed near the four corners of the lower template 11, and the four guide shafts 23 are vertically arranged. Two lower mold bases 25 are fixedly installed on the lower template 11, and a lower mold ejector pin 12 is fixedly installed on each of the lower mold bases 25. The inclined surface at the upper end of the lower mold ejector pin 12 is used to guide the bending of the spring piece 2. Two rebound bases 26 are fixedly installed on the lower template 11 located on one side of the lower mold ejector pin 12. An elastic element 13 is fixedly installed on the rebound base 26. In this embodiment, the elastic element 13 can be a spring. The top of the spring contacts the bottom of the transfer plate 9. When the upper template 6 is riveted and rises, the rebound force of the spring pushes the transfer plate 9 to rise to the initial position, so that the base 1 is separated from the lower mold ejector pin 12, avoiding the bending spring piece 2 from sticking to the ejector pin.

[0036] Please see Figure 6 , Figure 7 and Figure 8 The transfer plate 9 is provided with four linear bearings 24 that are slidably connected to four guide shafts 23 near its four corners. An auxiliary unloading assembly 14 is provided on the transfer plate 9. The auxiliary unloading assembly 14 includes a clamp fixing plate 141, a fixing clamp 142 and a second driving component 143. A guide slide support frame 18 is bolted to the transfer plate 9. Guide slide grooves 19 extending horizontally are provided on both sides of the guide slide support frame 18. The two ends of the clamp fixing plate 141 are slidably connected to the two guide slide grooves 19. Two fixing clamps 142 located directly above the lower mold ejector pin 12 are bolted to the clamp fixing plate 141. The fixing clamps 142 have fixing grooves 10 that match the shape of the base 1. The fixing grooves 10 are used to position and clamp the base 1. An opening is provided on the transfer plate 9 located directly below the fixing clamps 142, so that the lower mold ejector pin 12 can bend the spring piece 2 on the fixing clamp 142 through the opening.

[0037] A mounting plate 28 is bolted to the transfer plate 9 located on one side of the fixture fixing plate 141. In this embodiment, the second driving component 143 is a cylinder, and the cylinder body is bolted to the mounting plate 28. The cylinder piston rod is fixedly connected to one end of the fixture fixing plate 141. The second driving component 143 is used to drive the fixture fixing plate 141 to slide horizontally back and forth. This facilitates the removal of the processed base 1 from the processing area, making it convenient for operators to pick up the parts.

[0038] Please see Figure 6 and Figure 7 A first limiting post 20 is fixedly installed on the upper part of the transfer plate 9. The first limiting post 20 is vertically fixed to the upper surface of the transfer plate 9 to limit the downward stroke of the upper template 6 and prevent overload.

[0039] A second limiting post 21 is fixedly installed at the bottom of the transfer plate 9, which is vertically fixed to the bottom of the transfer plate 9 and cooperates with the limiting hole 22 to ensure accurate positioning when the transfer plate 9 is pressed down and to limit the downward stroke of the transfer plate 9 to prevent overload.

[0040] Please see Figure 6 and Figure 7 The upper template 6 is also provided with four linear bearings 24 that are slidably connected to four guide shafts 23; two upper mold bases 27 are fixedly provided on the lower surface of the upper template 6, and upper mold ejector pins 7 are fixedly provided on each upper mold base 27. The upper mold ejector pins 7 are located directly above the fixing groove 10 and correspond to the mounting holes 4 on the base 1; the ends of the upper mold ejector pins 7 are flat.

[0041] In this embodiment, the first driving component 8 is also a cylinder. The cylinder body is bolted to the frame 5, and one end of the piston rod of the cylinder is bolted to the upper middle part of the upper template 6. The first driving component 8 drives the upper template 6 to perform vertical reciprocating motion along the guide shaft 23 to realize the riveting action.

[0042] Brief description of the usage process: In the initial state, the auxiliary unloading component 14 pushes the fixture fixing plate 141 out of the processing area; the base 1 is placed into the fixing groove 10, and the spring piece 2 is pre-positioned on the mounting position 3 of the base 1; the auxiliary unloading component 14 then pulls the fixture fixing plate 141 back into the processing area; the first driving component 8 drives the upper template 6 to press down and drives the transfer plate 9 to press down, and then the upper template 6 and the lower template 11 cooperate to make the upper mold ejector pin 7 press and rivet the spring piece 2 into the mounting hole 4, while the inclined surface of the lower mold ejector pin 12 contacts and inserts the spring piece 2 into the mounting hole 4, so that it bends along the set angle; the first driving component 8 drives the upper template 6 to rise, while the spring pushes the transfer plate 9 to reset, and the base 1 is separated from the lower mold ejector pin 12; thus, it is convenient for the auxiliary unloading component 14 to push the fixture fixing plate 141 out of the processing area again, which is convenient for subsequent unloading work.

[0043] In summary, this invention, through automated production, ensures that the spring piece 2 is accurately riveted onto the base, and precisely controls parameters such as riveting depth and bending angle, ensuring that the processed product meets design requirements and satisfies customer precision needs; it can complete the processing work quickly and accurately, greatly improving production efficiency. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.
