Description

Technical Field

[0001] This utility model relates to the field of disc spring processing technology, specifically a disc spring processing structure. Background Technology

[0002] A disc spring is a mechanical component that resembles a circular washer. Disc springs are mainly used by stacking a considerable number of disc springs to provide elastic extension. The variable stiffness characteristics and compact installation of disc springs make them widely used in technical fields such as machinery, petroleum, automotive and aerospace industries.

[0003] Currently, most disc spring processing relies on stamping machines. During processing, the operator moves the steel strip under the stamping head of the stamping machine. The stamping head moves down to punch the disc spring out of the steel strip on the mold seat. Then the stamping head moves up to carry the disc spring out. Traditionally, the steel strip is moved manually for stamping, which has low production efficiency and makes it difficult to automatically feed another steel strip to stamp disc springs after one steel strip is finished. It is not convenient to process disc springs in a cyclical and efficient manner. Utility Model Content

[0004] The purpose of this utility model is to provide a disc spring processing structure to solve the problems mentioned in the background art.

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

[0006] A disc spring processing structure includes:

[0007] A base plate, on the top surface of which two U-shaped frames are fixed, and on the top surface of which two columns are fixed;

[0008] The main body of the stamping machine is fixed on the top of two C-shaped frames. A hydraulic cylinder is fixed inside the main body of the stamping machine. A stamping head is fixed at the output end of the hydraulic cylinder. A mold seat is fixed on the inner bottom surface of the main body of the stamping machine. The stamping head and the mold seat cooperate to stamp and cut out disc springs.

[0009] Multiple support components are installed between two U-shaped frames to support the steel strip;

[0010] Two shifting components are arranged at both ends of the press body. Each shifting component includes a guide frame one fixed to the column, a guide frame two screwed to the bottom of the guide frame one, a connecting rod screwed to the bottom of the guide frame two, a guide frame three fixed to the bottom of the connecting rod, and two clamping blocks screwed to the inside of the guide frame three.

[0011] Furthermore, multiple crossbeams are fixed between the two C-shaped frames, and a limit block is fixed to the outer side of one of the C-shaped frames.

[0012] Furthermore, the support assembly includes a support base one and a support base two, the support base one and the support base two are respectively fixedly connected to the corresponding C-shaped frame, and a roller is rotatably connected between the support base one and the support base two.

[0013] Furthermore, a lead screw is rotatably connected inside the first guide frame, a transmission seat that is screwed to the top of the second guide frame is fixed, and a motor that can drive the lead screw to rotate is fixed inside the main body of the press near one end of the first guide frame.

[0014] Furthermore, a lead screw is rotatably connected inside the guide frame 2, the lead screw 2 is screwed into the connecting rod, and a motor 1 capable of driving the lead screw 2 to rotate is fixed at one end of the guide frame 2.

[0015] Furthermore, a bidirectional lead screw is rotatably connected inside the guide frame three, and the bidirectional lead screw is screwed into the clamping block. A motor two capable of driving the bidirectional lead screw to rotate is fixed at the bottom of the guide frame three.

[0016] Furthermore, a limiting block 2 is fixed on one side of the press body, and a hopper is detachably fixed between the bottoms of the two C-shaped frames.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Motor 2 drives the bidirectional lead screw to rotate, causing two clamping blocks to hold and fix the steel strip. Motor 1 drives the lead screw 2 to rotate, allowing the connecting rod to move the steel strip back and forth below the guide frame 2 through the two clamping blocks. Motor 3 drives the lead screw 1 to rotate, causing the guide frame 2 to move left and right along the guide frame 1. The guide frame 2 then moves the steel strip clamped and fixed below the connecting rod left and right, thus enabling the moving component to move the steel strip to the stamping position instead of manually. By moving the position of the steel strip back and forth and left and right, the stamping head can cut disc springs in different areas of the steel strip surface, which helps to improve the efficiency of disc spring stamping.

[0019] 2. By setting a shifting component at both ends of the stamping machine body, the shifting component at the left end pushes the steel strip scrap after stamping to the right end of the stamping machine body. During the upward movement of the stamping head, the shifting component at the right end of the stamping machine body can clamp and fix one end of the steel strip scrap. At the same time, the shifting component at the left end of the stamping machine body releases the steel strip, making it easy to switch and fix the steel strip to the shifting component at the right end. The shifting component at the right end continues to move with the steel strip so that the left end of the steel strip can be stamped on the stamping machine body. When the steel strip is completely converted into scrap after processing and leaves the mold seat, the shifting component at the left end can clamp another steel strip and move it above the mold seat for processing and standby. This realizes that after one steel strip is processed, another steel strip is automatically connected to be fed to stamp the disc spring, which improves the efficiency of steel strip stamping and processing disc springs.

Detailed Implementation

[0026] 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.

[0027] Example 1, please refer to Figure 1 - Figure 5 In this embodiment of the utility model, a disc spring processing structure includes a base plate 100. Two U-shaped frames 110 are fixed to the top surface of the base plate 100. A stamping machine body 200 is fixed between the tops of the two U-shaped frames 110. A hydraulic cylinder 210 is fixed inside the stamping machine body 200. A stamping head 211 is fixed to the output end of the hydraulic cylinder 210. A mold base 220 is fixed to the inner bottom surface of the stamping machine body 200. The stamping head 211 cooperates with the mold base 220 to stamp and cut out disc springs. Multiple supports for steel strips are installed and fixed between the two U-shaped frames 110. The support assembly 300 has two columns 120 fixed on the top surface of the base plate 100. A shifting assembly 400 is provided between the columns 120 and the press body 200. The shifting assembly 400 includes a guide frame 410 fixed to the columns 120. One end of the guide frame 410 is fixed to the press body 200. A guide frame 420 is screwed into the bottom of the guide frame 410. A connecting rod 430 is screwed into the bottom of the guide frame 420. A guide frame 440 is fixed to the bottom of the connecting rod 430. Two clamping blocks 450 are screwed into the interior of the guide frame 440.

[0028] Specifically, by arranging shifting components 400 at both ends of the stamping machine body 200, two clamping blocks 450 on the shifting components 400 can clamp and fix the steel strip. Then, the shifting components 400 drive the steel strip to move back and forth and left and right, so that the steel strip can automatically move to the stamping station to process disc springs, eliminating the need for manual movement of the steel strip to process disc springs, which helps to improve the efficiency of disc spring processing. After the steel strip moves to the right end of the stamping machine body 200 after the multi-hole scrap end is formed by stamping, the shifting component 400 at the right end... During the upward movement of the pressure head 211, the scrap end of the steel strip is clamped and fixed. At the same time, the shifting component 400 on the left releases the steel strip, so that the steel strip is driven by the shifting component 400 on the right. When the steel strip is completely stamped and leaves the mold base 220, the shifting component 400 on the left will transport the pre-clamped spare steel strip back to the mold base 220 for stamping. Thus, the two shifting components 400 work together to make the steel strip continuously stamp the disc spring onto the stamping machine body 200, further improving the processing efficiency of the disc spring.

[0029] like Figure 1 and Figure 5 As shown, in this embodiment, multiple crossbeams are fixed between the two C-shaped frames 110, which helps to improve the firmness of the two C-shaped frames 110 being fixed to each other. A limiting block 111 is fixed to the outside of one C-shaped frame 110, and an L-shaped rod is fixed between the limiting block 111 and the corresponding C-shaped frame 110.

[0030] In this embodiment, when placing the steel strip onto the multiple support components 300 on the left end of the press body 200, one edge of the steel strip can be abutted against the inner side of the limiting block 111. In this way, when the two clamping blocks 450 on the shifting component 400 move toward the steel strip, the steel strip can be fully engaged between the two clamping blocks 450 on the shifting component 400 with the blocking effect of the limiting block 111.

[0031] In this embodiment, when placing the steel strip onto the multiple support components 300 on the left side of the press body 200, the connecting rod 430 can be moved in advance along the guide frame 420 in a direction away from the support components 300 to leave a larger placement space for the steel strip. The steel strip can be placed using an industrial robot in the prior art, which improves the efficiency of steel strip placement.

[0032] like Figure 5 As shown, in this embodiment, the support assembly 300 includes a first support base 310 and a second support base 320. The first support base 310 and the second support base 320 are respectively fixedly connected to the corresponding C-shaped frame 110. A roller 330 is rotatably connected between the first support base 310 and the second support base 320.

[0033] In this embodiment, every two rollers 330 constitute a set of support rollers. The two support roller sets at the left end of the press body 200 can support the steel strip from both ends, satisfying the initial feeding of the steel strip. The support roller set at the right end of the press body 200 can support the steel strip scrap, making it convenient for the right-end shifting component 400 to clamp the steel strip scrap. The rollers 330 on the support roller set are in a rolling contact relationship with the steel strip, which helps to reduce the resistance during the movement of the steel strip. There is a large gap between the two support roller sets at the left end of the press body 200, which makes it easier to leave space for the left-end shifting component 400 to move with the steel strip.

[0034] like Figure 1 and Figure 4As shown, in this embodiment, a lead screw 411 is rotatably connected inside the first guide frame 410, a transmission seat 422 that is screwed into the lead screw 411 is fixed at the top of the second guide frame 420, a motor 3 that can drive the lead screw 411 to rotate is fixed inside the press body 200 near one end of the first guide frame 410, a lead screw 421 is rotatably connected inside the second guide frame 420, the lead screw 421 is screwed into the connecting rod 430, a motor 423 that can drive the lead screw 421 to rotate is fixed at one end of the second guide frame 420, a bidirectional lead screw 441 is rotatably connected inside the third guide frame 440, the bidirectional lead screw 441 is screwed into the clamping block 450, and a motor 442 that can drive the bidirectional lead screw 441 to rotate is fixed at the bottom of the third guide frame 440.

[0035] In this embodiment, motor 2 442 drives the bidirectional lead screw 441 to rotate, causing the two clamping blocks 450 to move closer to each other along the guide frame 3 440, which facilitates clamping and fixing one edge of the steel strip on the support assembly 300. Then, motor 3 drives the lead screw 1 411 to rotate, causing the transmission seat 422 to move along the bottom of the guide frame 1 410 towards the stamping station with the guide frame 2 420, so that the steel strip can be moved under the stamping head 211 for stamping. After one stamping, motor 1 423 drives the lead screw 2 421 to rotate, causing the connecting rod 430 to move the steel strip backward along the guide frame 2 420, so that different positions of the steel strip in the width direction are moved to the stamping head 211 for stamping. After the steel strip is fully processed in the width direction, the steel strip is moved to the right again, so that the steel strip changes the stamping position in the length direction, thereby realizing the processing of disc springs by stamping the steel strip in all directions.

[0036] like Figure 2 and Figure 3 As shown, in this embodiment, a limiting block 250 is fixed on one side of the press body 200. When the scrap material on the right end needs to be automatically released, the shifting component 400 on the right end moves the steel strip towards the limiting block 250, so that one edge of the steel strip abuts against the inside of the limiting block 250. Then, the two clamping blocks 450 on the shifting component 400 move away from each other and no longer clamp the steel strip. After the clamping block 450 releases the steel strip, it continues to move away from the steel strip. When the clamping block 450 disengages from the steel strip, one end of the steel strip loses the clamping support of the clamping block 450 and will automatically flip and fall to the ground, realizing the automatic delivery of scrap steel plates.

[0037] like Figure 1 and Figure 3As shown, in this embodiment, a hopper 500 is detachably fixed between the bottoms of the two C-shaped frames 110. The hopper 500 is arranged below the stamping station and can hold the disc spring. In addition, a material-pushing structure can be installed below the stamping head 211 in the art, which can throw the disc spring carried by the stamping head 211 towards the hopper 500 from one direction when the stamping head 211 moves upward. The material-pushing structure is prior art and will not be described in detail here.

[0038] In this embodiment, a fixed cloth bag can be attached to the bottom of the hopper 500 to facilitate the direct holding of the processed disc springs. Specifically, the stamping process involves the extension of the output end of the hydraulic cylinder 210 to allow the steel strip on the stamping die seat 220 of the stamping head 211 to complete the processing of the disc springs. This part is prior art, and the specific stamping principle will not be elaborated.

[0039] like Figure 3 As shown, in this embodiment, the bottom of the mold base 220 can be designed as a slope, so that the disc spring that accidentally falls onto the mold base 220 can automatically fall into the hopper 500 along the slope, and the guide shaft 230 on the press body 200 facilitates the stable up and down movement of the press head 211.

[0040] like Figure 2 As shown, in this embodiment, a protective cover 240 is also installed on the outside of the press body 200 to protect the internal structure of the press body 200.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
