Description

Technical Field

[0001] The present invention belongs to the technical field of the processing of e-type spring clips, and particularly relates to a material discharging device for an e-type spring clip winding machine with the invention name. Background Art

[0002] The e-type spring clip is a locking fastener, mainly used as a locking connection piece on tracks. Specifically, on urban rail transit tracks, the e-type spring clip is used to connect the track and the subrail foundation into one body. Because the e-type spring clip has elastic force, it can also play a buffering role.

[0003] Due to the wide range of applications of the e-type spring clip, many technical improvements in the processing of e-type spring clips have been publicly reported. For example, the Chinese patent application number is: CN201911398826.7, which discloses an e-type spring clip pre-press and discloses the following technical solution:

[0004] The pre-press includes a main machine and a feeding mechanism; the main machine includes a frame, a spring clip pre-press mounting plate, an oil cylinder, and a pressing head. The spring clip pre-press mounting plate is installed on the frame. The space between the spring clip pre-press mounting plate and the working surface of the frame is the pre-press station. The oil cylinder is installed on the top of the frame, and the pressing head is installed on the oil cylinder and is driven by the oil cylinder to press down. It passes through the spring clip pre-press mounting plate and presses on the surface of the e-type spring clip; the feeding mechanism includes a movable frame, a spring clip bracket, a spring clip bracket guide rail, and a bracket cylinder. The movable frame can move horizontally. The spring clip bracket guide rail is vertically arranged and installed on the movable frame. The spring clip bracket is slidably assembled on the spring clip bracket guide rail. The bracket cylinder is installed on the movable frame and drives the spring clip bracket. The spring clip bracket is used to place the e-type spring clip and send it to the pre-press station. Through the above technical solution, the production efficiency and the quality level of the process are improved, and the safety risk is reduced.

[0029] The present invention discloses a blanking device for an E-type elastic strip winding machine. In the device structure disclosed by the present invention, the following beneficial effects are achieved:

[0030] 1. In the device structure disclosed by the present invention, a blanking mechanism is adopted. Specifically, a blanking disc slidably connected to a forming die, a pushing disc corresponding to the blanking disc is slidably connected to the right side of the main shaft, a pushing rod passes through the main shaft to connect the blanking disc and the pushing disc, a blanking oil cylinder, a piston rod of the blanking oil cylinder is assembled and connected with a fork plate, the fork plate is arranged on the right side of the pushing disc, the fork plate includes a fork opening part for pushing the pushing disc, the fork opening part is integrally formed with a fork arm part, and the piston rod of the blanking oil cylinder is fixedly connected to the fork arm part. When the blanking oil cylinder pushes the fork plate, the fork opening part on the fork plate pushes the pushing disc. Due to the fork opening part design, the contact surface with the pushing disc can be large. Therefore, during the pushing process, the stress surface is uniform, resulting in the pushing disc being able to stably push the pushing disc. The pushing disc drives the pushing rod to push the blanking disc to slide relative to the forming die.

[0045] As Figure 1-8 shown, a material discharging device for an E-type elastic strip winding machine includes a material discharging frame 1, and the material discharging frame 1 includes a vertical frame and a base portion assembled and connected to the bottom of the vertical frame.

[0046] A bearing seat 22 is assembled and connected to the material discharging frame 1 (specifically at the vertical frame part), a slewing bearing 221 is assembled and connected to the bearing seat 22, a main shaft 2 is rotatably connected to the slewing bearing 211 (therefore, the main shaft 2 can rotate relative to the slewing bearing), and a forming die 7 is fixedly assembled and connected to the left side of the main shaft 2. During the working process, a bar stock (the bar stock is the processing material for the E-type elastic strip) is inserted on the forming die 7, and the main shaft 2 rotates. During the rotation process, the main shaft 2 drives the forming die 7 to rotate, thereby forming the bar stock into a semi-finished E-type elastic strip 6.

[0047] A swing oil cylinder 3 is assembled and connected to the main shaft 2, and the main shaft 2 rotates through the swing oil cylinder 3.

[0048] According to the existing method, the cylinder block of the swing oil cylinder 3 is assembled and connected with a cylinder block seat, and the cylinder block seat is fixedly assembled on the material discharging frame 1; a support frame for supporting the main shaft 2 is fixedly connected to the top of the cylinder block seat, and the main shaft 2 is slidably connected to the support frame.

[0049] After the above processing, an e-shaped spring bar semi-finished product 6 is formed. In order to realize accurate material removal, a material removal mechanism 21 is assembled and connected to the main shaft 2.

[0050] The specific structure of the material-returning mechanism 21 is as follows:

[0051] The material return mechanism 21 includes a material return plate 215 slidably connected to the forming mold 7 , and a material pusher plate 211 corresponding to the material return plate 215 is slidably connected to the right side of the spindle 2 ; a plurality of material pusher rods 212 are assembled and connected between the material pusher plate 211 and the material return plate 215 .

[0052] Three linear bearings 23 are fixedly assembled and connected on the main shaft 2 (specifically, the longitudinal cross-section of the main shaft 2 is T-shaped, and an assembly hole for assembling and installing the linear bearings 23 is provided at the end position, and the linear bearings 23 are installed in the assembly holes on the main shaft 2), and the above-mentioned push rod 212 passes through the linear bearings 23 (and is connected to the linear bearings 23 by a sliding connection). This design method realizes that the push rod 212 is driven to rotate during the rotation of the main shaft 2, and the push rod 212 can perform linear motion relative to the linear bearings 23.

[0053] The material return mechanism 21 also includes a material return cylinder 214 assembled and connected to the top right side of the material return frame 1 (the bottom of the material return cylinder 214 is fixedly connected to a cylinder seat 2141, and the cylinder seat 2141 is fixedly assembled on the material return frame 1), and the piston rod of the material return cylinder 214 is assembled and connected to a fork plate 213, and the fork plate 213 is arranged on the right side of the pushing plate 211.

[0054] Specifically, the fork plate 213 includes a fork mouth portion that pushes the push plate 211, and the fork mouth portion is integrally formed with a fork arm portion, and the piston rod of the material-removing oil cylinder 214 is fixedly connected to the fork arm portion. When the material-removing oil cylinder 214 pushes the fork plate 213, the fork mouth portion on the fork plate 213 pushes the material-removing oil cylinder 214. Due to the fork mouth design, the surface that can contact the material-removing oil cylinder 214 is large, so during the pushing process, the force-bearing surface is uniform, so that the fork plate 213 can steadily push the material-removing oil cylinder 211, and the material-removing oil cylinder 214 drives the push rod 212 to push the material-removing oil cylinder 214 to slide relative to the forming mold 7. At this time, under the action of the material-removing oil cylinder 214, the e-shaped spring bar semi-finished product 6 slides off the forming mold 7.

[0055] In actual working process, several adjustable push rods are installed on the side wall of the unloading tray 215 facing the e-shaped spring bar semi-finished product 6, which are specifically connected to the unloading tray through threads and the height is adjusted by the threads. Several thrust points can be adjusted to the same plane to make the force on the rod more uniform.

[0056] In order to stably receive the semi-finished E-shaped elastic rail clips 6 that slide down from the forming die 7 and facilitate the pushing to the next process, the above-mentioned unloading device for the semi-finished E-shaped elastic rail clips 6 winding machine further includes a receiving mechanism 4 arranged on the right side at the top of the unloading rack 1, and the semi-finished E-shaped elastic rail clips 6 unloaded from the forming die 7 are received by the receiving mechanism 4.

[0057] Specifically, the receiving mechanism 4 includes a clamping cylinder 44 arranged on the right side of the main shaft 2, and a parallel gripper 42 for gripping the semi-finished E-shaped elastic rail clips 6 is assembled and connected to the clamping cylinder 44; when the clamping cylinder 44 is opened, the parallel gripper 42 grips the semi-finished E-shaped elastic rail clips 6.

[0058] The clamping method is as follows:

[0059] When the semi-finished E-shaped elastic rail clips 6 fall onto the parallel gripper 42, under the action of the clamping cylinder 44, the parallel gripper 42 moves outwards, and the inner side of the semi-finished E-shaped elastic rail clips 6 is turned outwards to clamp the semi-finished E-shaped elastic rail clips 6 in an "expanding" manner.

[0060] The above-mentioned receiving mechanism 4 further includes a telescopic cylinder 41. The piston rod of the telescopic cylinder 41 is fixedly connected with a bearing seat plate 411. A U-shaped seat 4111 is assembled and connected to the bearing seat plate 411. A mounting plate is fixedly assembled and connected to the U-shaped seat 4111, and the right side wall of the cylinder body of the clamping cylinder 44 is fixedly assembled on the mounting plate.

[0061] The mounting plate is fixedly connected with a plurality of assembly rods 4311 towards the left. A receiving claw mounting disc 431 is fixedly connected between the assembly rods 4311. A plurality of profiling receiving claws 43 are fixedly connected to the left side wall of the receiving claw mounting disc 431. The profiling receiving claws 43 are designed according to the geometric shape of the semi-finished E-shaped elastic rail clips 6. The semi-finished E-shaped elastic rail clips 6 unloaded and dropped first enter the profiling receiving claws 43 and can be stably placed on the profiling receiving claws 43, and finally are clamped by the above-mentioned clamping cylinder 44. The profiling receiving claws 43 are composed of several cylinders, and the curve formed by the outer contour line of the cylinders coincides with the inner curve of the formed semi-finished E-shaped elastic rail clips.

[0062] The stable clamping of the semi-finished E-shaped elastic rail clips 6 is achieved through the above method.

[0063] A rotary blanking component 5 is assembled and connected to the right side at the top of the above-mentioned unloading rack 1; the cylinder body of the telescopic cylinder 41 is rotated by the rotary blanking component 5. After the clamped semi-finished E-shaped elastic rail clips 6 need to enter the next process, at this time, the telescopic cylinder 41 carries the semi-finished E-shaped elastic rail clips 6 and moves to the right, and then uses the rotary blanking component 5 for rotary blanking.

[0064] Specifically, the rotary blanking component 5 includes a rotary cylinder 51 (the rotary blanking component 5 further includes a cylinder body frame 511, and the cylinder body of the rotary cylinder 51 is fixedly assembled on the cylinder body frame 511); the rotary cylinder 51 is fixedly assembled with a rotary flange, and the rotary flange is assembled and connected with a rotary shaft (the rotary shaft is assembled and connected with a shaft seat 52, and the shaft seat 52 is assembled on the cylinder body frame 511), the rotary shaft is assembled and connected with a telescopic cylinder bottom plate 521, and the cylinder body of the telescopic cylinder 41 is fixedly assembled on the telescopic cylinder bottom plate 521).

[0065] Specifically, the above-mentioned telescopic cylinder bottom plate 521 is fixedly assembled at the installation end of the end position of the rotary shaft.

[0066] Under the rotation of the rotary cylinder 51, the semi-finished E-type elastic strip 6 (the semi-finished E-type elastic strip 6 rotates and blanks together with the telescopic cylinder 41 at this time, moves to the designated section, and is further processed).

[0067] Specifically, under the rotation of the rotary cylinder 51, the semi-finished E-type elastic strip 6 is blanked onto the receiving rack. Specifically, in the actual working process, a receiving rack is designed on the blanking rack 1 to facilitate the receiving of the processed semi-finished E-type elastic strip 6.

[0068] The top of the above-mentioned blanking rack 1 is assembled and connected with a motor 11 and an oil pump 12. High-pressure oil is formed by the motor 11 and the oil pump 12. According to the existing working connection method, the oil pump 12 pumps the high-pressure oil into the swing oil cylinder 3 and the blanking oil cylinder 214 to provide power for the swing oil cylinder 3 and the blanking oil cylinder 214.

[0069] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present invention should also fall within the protection scope of the present invention.
