Description

Technical Field

[0001] The present invention relates to the technical field of rim processing, and particularly relates to a hub plate cutting and bending machine set. Background Art

[0002] A hub is a cylindrical metal component with an inner profile that supports a tire and is centered on an axle. The hub is one of the important moving parts of an automobile, and has high requirements for its performance, weight, and service life. The structure of the hub includes a rim and a spoke surface. When processing an automobile rim, a cutting and bending device is required. First, the sheet material is cut to the required size, and then the sheet material is bent and formed into the required rim. Among them, the cutting part of the cutting and bending device usually uses a blanking press, and the bending part usually uses a plate rolling machine.

[0003] After the sheet material is processed and formed by the cutting and bending device, the sheet material (subsequently referred to as "rim semi-finished product") that has completed the bending operation is pushed out by a pushing mechanism. After the worker takes the rim semi-finished product, it is placed in a collection box for collection. However, due to the heavy weight of the rim semi-finished product, it is laborious for workers to carry it, and the burrs on the edge of the rim semi-finished product may cause accidental hand scratches during the handling by workers. Summary of the Invention

[0004] The purpose of the present invention is to provide a hub plate cutting and bending machine set, which can automatically collect rim semi-finished products and facilitate the transfer to subsequent workstations.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: A hub plate cutting and bending machine set includes a blanking press, a plate rolling machine, a conveying device arranged between the blanking press and the plate rolling machine and used for conveying the sheet material, a collection device for collecting rim semi-finished products, and a discharging device for conveying the rim semi-finished products processed on the plate rolling machine into the collection device. There are three plate rolling shafts on the front side of the plate rolling machine for receiving the sheet material from the conveying device and realizing bending. A push plate is telescopically arranged on the front side of the plate rolling machine, on both sides and above the uppermost plate rolling shaft, and used for pushing the rim semi-finished product out of the three plate rolling shafts. The push plate is driven by a cylinder. The discharging device includes a frame, an inclined discharging channel arranged on the frame, and a deceleration mechanism arranged in the inclined discharging channel and used for reducing the rolling speed of the rim semi-finished product in the inclined discharging channel. An opening for the rim semi-finished product pushed out from the plate rolling machine to enter is arranged on one side of the upper end of the inclined discharging channel. The collection device includes a base arranged on the ground and having tracks on both sides, a plurality of collection boxes arranged side by side and slidably connected to the tracks and used for receiving the rim semi-finished products from the inclined discharging channel, and a positioning mechanism arranged between the base and any one of the collection boxes and used for aligning the collection box with the inclined discharging channel. Universal wheels are respectively arranged on both sides at both ends of the collection box and used for supporting on the ground when the collection box is slidably connected to the tracks.

[0006] By adopting the above technical solution, after the sheet material is processed by a blanking punching machine and a plate rolling machine, the semifinished wheel rim is pushed into the inclined discharge channel by the push plate of the plate rolling machine, and the semifinished wheel rim rolls into the collection box along the inclined discharge channel for collection. When the semifinished wheel rim rolls in the inclined discharge channel, its rolling speed is reduced by a speed reduction mechanism. At the same time, after a batch of semifinished wheel rims are collected in the collection box, the collection box can be directly detached from the base and the slide rail through the universal wheels at the bottom and move. The next collection box moves along the slide rail and is positioned by a positioning mechanism to align with the inclined discharge channel, so as to continue collecting the semifinished wheel rims; finally, it has the function of automatically collecting the semifinished wheel rims and facilitating the transfer to the subsequent workstations.

[0007] The further setting of the present invention is as follows: The speed reduction mechanism includes two support plates symmetrically arranged on both sides below the inclined discharge channel and having limit chutes on the end faces close to each other, two rotating sleeves slidably connected in the two limit chutes, a blocking shaft rotatably connected between the two rotating sleeves, two guide shafts with one end hinged to the bottom of both sides of the inclined discharge channel and the other end passing through the rotating sleeves, and compression springs sleeved on the guide shafts and driving the rotating sleeves to move upward towards the upper part of the inclined discharge channel; The limit chute includes a first chute portion extending along the length direction of the inclined discharge channel, a second chute portion with one end communicating with the lower end of the first chute portion and extending vertically upward from the first chute portion, and a third chute portion with one end connected to the upper end of the second chute portion and the other end connected to the middle of the first chute portion; The third chute portion is arc-shaped. During the process of the rotating sleeve moving towards the first chute portion along the third chute portion, the compression spring gradually restores its elastic deformation; During the process of the semifinished wheel rim rolling along the inclined discharge channel, the acting force of the semifinished wheel rim on the blocking shaft can overcome the elastic force of the compression spring, so that the rotating sleeve moves along the first chute portion and the second chute portion to the upper end of the second chute portion; When the blocking shaft is located in the first chute portion, the distance from the center line of the blocking shaft to the bottom of the inclined discharge channel is greater than the distance from the center line of the semifinished wheel rim to the bottom of the inclined discharge channel; When the rotating sleeve is located at the upper end of the second chute portion, the semifinished wheel rim passes under the blocking shaft.

[0008] By adopting the above technical solution, when the semifinished wheel rim rolls along the inclined discharge channel, first, the semifinished wheel rim hits the blocking shaft in the first chute portion. The acting force of the semifinished wheel rim on the blocking shaft can overcome the elastic force of the compression spring, so that the blocking shaft moves along the first chute portion and the second chute portion to the upper end of the second chute portion. During this process, the semifinished wheel rim can be decelerated and it is ensured that the semifinished wheel rim passes through the blocking shaft. At the same time, when the blocking shaft moves to the upper end of the second chute portion, under the reset action of the compression spring, the blocking shaft moves along the third chute portion to the first chute portion and resets, realizing the function of automatically decelerating the semifinished wheel rim when it passes through.

[0009] A further setting of the present invention is as follows: a feed inlet is provided on one side of the collection box close to the inclined discharge channel, a discharge outlet with a height lower than that of the feed inlet is provided on the side of the collection box away from the inclined discharge channel, an inclined plate communicating the feed inlet and the discharge outlet is arranged inside the collection box, a material taking hopper communicating with the discharge outlet and for placing a single semi-finished rim is arranged on one side of the collection box, the upper surface of the material taking hopper is flat, and half of the semi-finished rim protrudes from the material taking hopper.

[0010] By adopting the above technical solution, when it is necessary to take out the semi-finished rims in the collection box for processing at subsequent workstations, the provided material taking hopper facilitates taking out the semi-finished rims one by one, and the setting of the inclined plate enables the semi-finished rims entering from the feed inlet to automatically roll to the position of the material taking hopper.

[0011] A further setting of the present invention is as follows: the material taking hopper is arranged to be liftable on the side of the collection box, a first elastic connection component for driving the collection box to move upward is arranged between the bottom of the material taking hopper and the collection box, a limiting block seat matched with one side of the bottom of the semi-finished rim is arranged at the end of the inclined plate close to the discharge outlet to be liftable, a second elastic connection component for driving the limiting block seat to move upward is arranged between the limiting block seat and the collection box, and a linkage component is arranged between the first elastic connection component and the second elastic connection component; when no semi-finished rim is placed in the material taking hopper, the bottom of the material taking hopper and the bottom of the inclined plate are on the same plane, and the limiting block seat does not protrude from the inclined plate; in the process that the previous semi-finished rim falls into the material taking hopper and overcomes the elastic force of the first elastic connection component to cause the material taking hopper to move downward, the linkage component gradually cancels the downward acting force on the second elastic component, and the second elastic connection component drives the limiting block seat to move upward to prevent the subsequent semi-finished rim from passing through the discharge outlet; when the semi-finished rim in the material taking hopper is taken out, the first elastic connection component drives the material taking hopper to reset upward, and the linkage component overcomes the elastic force of the second elastic component to reset the limiting block seat.

[0012] By adopting the above technical solution, when the semi-finished rim located in the material taking hopper is taken out one by one, the circumferences of adjacent semi-finished rims are in contact with the circumference of the semi-finished rim located in the material taking hopper, and the semi-finished rim located on the inclined plate has a downward acting force on the semi-finished rim located in the material taking hopper, resulting in relatively difficult removal of the semi-finished rim in the material taking hopper; at this time, through the lifting setting of the material taking hopper and the settings of the first elastic connection assembly, the second elastic connection assembly, and the linkage assembly, the following motion states are achieved: (1) When there is no semi-finished rim placed in the material taking hopper, the bottom of the material taking hopper and the bottom of the inclined plate are on the same plane, and the limit retaining seat does not protrude from the inclined plate; (2) During the process that the previous semi-finished rim falls into the material taking hopper and overcomes the elastic force of the first elastic connection assembly and causes the material taking hopper to move downward, the linkage assembly gradually cancels the downward acting force on the second elastic assembly, and the second elastic connection assembly drives the limit retaining seat to move upward to prevent the subsequent semi-finished rim from passing through the discharge port; (3) When the semi-finished rim located in the material taking hopper is taken out, the first elastic connection assembly drives the material taking hopper to reset upward, and the linkage assembly overcomes the elastic force of the second elastic assembly to reset the limit retaining seat; ultimately, it has the effect of facilitating the removal of the semi-finished rim located in the material taking hopper.

[0013] The further setting of the present invention is: The first elastic connection assembly includes a first connection seat arranged on the collection box and below the material taking hopper, two first telescopic shafts arranged at the bottom of the material taking hopper and passing through the first connection seat, and two first return springs sleeved on the first telescopic shafts and with both ends abutted between the first connection seat and the lower surface of the material taking hopper; The second elastic connection assembly includes a second connection seat arranged on the collection box and below the limit retaining seat, two second telescopic shafts arranged at the bottom of the limit retaining seat and passing through the second connection seat, and two second return springs sleeved on the second telescopic shafts and with both ends abutted between the second connection seat and the lower surface of the limit retaining seat; The linkage assembly includes a fixed pulley rotatably connected to the collection box and a cable with both ends connected between the lower ends of the first telescopic shafts and bypassing the fixed pulley.

[0014] By adopting the above technical solution, when the semi-finished rim enters the material taking hopper, the overall weight of the material taking hopper increases, thereby overcoming the elastic force of the first return spring, causing the material taking hopper and the first telescopic shaft to move downward. At this time, the cable connecting the lower ends of the first telescopic shafts gradually becomes loose, the pulling force of the cable on the lower end of the second telescopic shaft decreases and provides the stroke distance for the upward movement of the second telescopic shaft. At this time, when the second return spring resets and drives the limit retaining seat to protrude from the inclined plate, it blocks the subsequent semi-finished rims from moving towards the material taking hopper.

[0015] A further arrangement of the present invention is that the material taking hopper is arranged to be lifted and lowered on the side of the collection box. An elastic intermittent connection assembly is provided between the bottom of the material taking hopper and the collection box, which drives the collection box to move downward after receiving the rim semi-finished product, and first remains fixed and then resets upward when taking out the rim semi-finished product. A limiting piece is arranged on one side of the material taking hopper close to the collection box. When the material taking hopper moves downward to the limit state after receiving the rim semi-finished product, the limiting piece blocks the discharge port to prevent the next rim semi-finished product from passing through the discharge port.

[0016] A further arrangement of the present invention is that the elastic intermittent connection assembly includes a third connection seat arranged below the collection box, two third telescopic shafts arranged at the bottom of the material taking hopper and passing through the third connection seat, two third return springs sleeved on the third telescopic shafts and with both ends abutted between the third connection seat and the lower surface of the material taking hopper, a first suction cup arranged below the third telescopic shaft, and a second suction cup arranged on the collection box and aligned with the first suction cup. When the material taking hopper moves to the limit state after receiving the rim semi-finished product, the first suction cup and the second suction cup are adsorbed to each other.

[0017] By adopting the above technical solution, when the rim semi-finished product enters the material taking hopper, the overall weight of the material taking hopper increases, thereby overcoming the elastic force of the third return spring, causing the material taking hopper and the third telescopic shaft to move downward. At this time, the limiting piece on the material taking hopper blocks the discharge port to prevent the next rim semi-finished product from passing through the discharge port, and the first suction cup and the second suction cup are adsorbed to each other. When the rim semi-finished product in the material taking hopper is taken out, the third return spring has a tendency to reset. After gradually overcoming the suction force of the first suction cup and the second suction cup, the material taking hopper resets, enabling the next rim semi-finished product to move into the material taking hopper.

[0018] A further arrangement of the present invention is that the positioning mechanism includes a positioning block arranged to be lifted and lowered on the base, a lifting cylinder arranged between the base and the positioning block, and a plurality of positioning sleeves arranged in the middle below the collection box for the positioning block to be inserted into. The opening of the positioning sleeve is flared.

[0019] By adopting the above technical solution, when the collection box moves into place, the lifting cylinder drives the positioning block to move upward and insert into the positioning sleeve at the bottom of the collection box. Combined with the fact that the collection box is slidably connected to the slide rail, the collection box can be positioned to align with the inclined discharge channel.

[0020] A further arrangement of the present invention is that one side of the collection box has two plug sockets with openings upward. A notch is arranged on the side of the plug socket away from the collection box. On the other side of the collection box, there are two plug-in parts that are used to be inserted into the adjacent plug sockets of the collection box after being lifted upward. The plug-in part includes a plug shaft arranged on the collection box and inserted into the notch, and a circular plug-in piece arranged at the end of the plug shaft and inserted into the plug socket.

[0021] By adopting the above technical solution, when the collection box for collecting the semi-finished rim moves to the next process, one collection box can be lifted upward so that the plug-in part is installed in the plug-in sleeve of another collection box, thereby facilitating the simultaneous transportation after multiple collection boxes are spliced together.

[0022] A further setting of the present invention is that: a channel is formed among the blanking punching press, the plate rolling machine, and the conveying device, the base passes through the channel, and the collection box does not interfere with the blanking punching press, the plate rolling machine, and the conveying device during the movement from the rear end to the front end of the base.

[0023] By adopting the above technical solution, when the semi-finished rim disengages from the plate rolling machine, at this time, the corresponding collection box needs to be located in front of the blanking punching press, the plate rolling machine, and the conveying device. After the collection of this collection box is completed, it can move quickly from the front side. At this time, the formation of the channel provides space for the arrangement of multiple collection boxes at the rear side. Description of the Drawings

Detailed implementation mode

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Embodiment 1: A hub plate blanking and bending rolling unit, as Figure 1 shown, includes a blanking punching press 1, a plate rolling machine 2, a conveying device 3 arranged between the blanking punching press 1 and the plate rolling machine 2 and realizing the conveying of sheet materials, a collecting device 4 for collecting rim semi-finished products, and an unloading device 5 for conveying the rim semi-finished products processed on the plate rolling machine 2 into the collecting device 4. There are three plate rolling shafts 21 on the front side of the plate rolling machine 2 for receiving the sheet materials from the conveying device 3 and realizing bending and rolling. A push plate 22 is telescopically arranged on the front side of the plate rolling machine 2 on both sides and above the uppermost plate rolling shaft 21 and pushing the rim semi-finished products out of the three plate rolling shafts 21. The push plate 22 is driven by a cylinder.

[0028] As Figures 1 to 3 shown, the unloading device 5 includes a frame 51, an inclined unloading channel 52 arranged on the frame 51, and a deceleration mechanism 53 arranged in the inclined unloading channel 52 and reducing the rolling speed of the rim semi-finished products in the inclined unloading channel 52. An opening for the rim semi-finished products pushed out from the plate rolling machine 2 to enter is arranged on one side of the upper end of the inclined unloading channel 52.

[0029] As Figures 2 to 4As shown in the figure, the speed reduction mechanism 53 includes two support plates 531 symmetrically arranged on both sides below the inclined discharge channel 52 and having limit sliding grooves 5311 on the end faces close to each other, two rotating sleeves 532 slidably connected in the two limit sliding grooves 5311, a blocking shaft 533 rotatably connected between the two rotating sleeves 532, two guiding shafts 534 with one end hinged to the bottoms on both sides of the inclined discharge channel 52 and the other end passing through the rotating sleeves 532, and compression springs 535 sleeved on the guiding shafts 534 and driving the rotating sleeves 532 to move upward towards the inclined discharge channel 52. The limit sliding groove 5311 includes a first sliding groove portion 53111 extending along the length direction of the inclined discharge channel 52, a second sliding groove portion 53112 with one end communicating with the lower end of the first sliding groove portion 53111 and extending vertically upward perpendicular to the first sliding groove portion 53111, and a third sliding groove portion 53112 with one end connected to the upper end of the second sliding groove portion 53112 and the other end connected to the middle of the first sliding groove portion 53111; the third sliding groove portion 53112 is arc-shaped, and during the process of the rotating sleeve 532 moving along the third sliding groove portion 53112 towards the first sliding groove portion 53111, the compression spring 535 gradually restores its elastic deformation. During the process of the rim semi-finished product rolling down along the inclined discharge channel 52, the acting force of the rim semi-finished product on the blocking shaft 533 can overcome the elastic force of the compression spring 535, so that the rotating sleeve 532 moves along the first sliding groove portion 53111 and the second sliding groove portion 53112 to the upper end of the second sliding groove portion 53112. When the blocking shaft 533 is located in the first sliding groove portion 53111, the distance from the center line of the blocking shaft 533 to the bottom of the inclined discharge channel 52 is greater than the distance from the center line of the rim semi-finished product to the bottom of the inclined discharge channel 52; when the rotating sleeve 532 is located at the upper end of the second sliding groove portion 53112, the rim semi-finished product passes under the blocking shaft 533.

[0030] As Figure 1 and Figure 2 shown in the figure, the collection device 4 includes a base 41 arranged on the ground and having tracks on both sides, a plurality of collection boxes 42 arranged side by side and slidably connected to the tracks to receive the material from the inclined discharge channel 52, and a positioning mechanism 43 arranged between the base 41 and any one of the collection boxes 42 to align the collection box 42 with the inclined discharge channel 52. Universal wheels 421 are respectively arranged on both sides at both ends of the collection box 42 to support on the ground when the collection box 42 is slidably connected to the tracks. A channel is formed among the blanking punching machine 1, the plate rolling machine 2, and the conveying device 3, the base 41 passes through the channel, and the collection box 42 does not interfere with the blanking punching machine 1, the plate rolling machine 2, and the conveying device 3 during the process of moving from the rear end to the front end of the base 41.

[0031] As Figure 2 and Figure 5As shown, on one side of the collection box 42 close to the inclined discharge channel 52, there is a feed inlet 422. On the side of the collection box 42 away from the inclined discharge channel 52, there is a discharge outlet 423 with a height lower than that of the feed inlet 422. An inclined plate 424 communicating the feed inlet 422 and the discharge outlet 423 is arranged inside the collection box 42, and one end of the inclined plate 424 passes through the feed inlet 422. On one side of the collection box 42, there is a material taking hopper 44 communicating with the discharge outlet 423 and for placing a single semi-finished rim. The upper surface of the material taking hopper 44 is flat, and half of the semi-finished rim protrudes from the material taking hopper 44.

[0032] As Figure 5 and Figure 7 As shown, the material taking hopper 44 is arranged on the side of the collection box 42 in a lifting manner. A first elastic connection component 46 for driving the collection box 42 to move upward is arranged between the bottom of the material taking hopper 44 and the collection box 42. A limit retaining seat 45 matching one side of the bottom of the semi-finished rim is arranged at one end of the inclined plate 424 close to the discharge outlet 423 in a lifting manner. A second elastic connection component 47 for driving the limit retaining seat 45 to move upward is arranged between the limit retaining seat 45 and the collection box 42. A linkage component 48 is arranged between the first elastic connection component 46 and the second elastic connection component 47. When there is no semi-finished rim placed in the material taking hopper 44, the bottom of the material taking hopper 44 and the bottom of the inclined plate 424 are on the same plane, and the limit retaining seat 45 does not protrude from the inclined plate 424. In the process that the previous semi-finished rim falls into the material taking hopper 44 and overcomes the elastic force of the first elastic connection component 46 to make the material taking hopper 44 move downward, the linkage component 48 gradually cancels the downward acting force on the second elastic component, and the second elastic connection component 47 drives the limit retaining seat 45 to move upward to prevent the next semi-finished rim from passing through the discharge outlet 423. When the semi-finished rim in the material taking hopper 44 is taken out, the first elastic connection component 46 drives the material taking hopper 44 to reset upward, and the linkage component 48 overcomes the elastic force of the second elastic component to reset the limit retaining seat 45.

[0033] As Figure 5 and Figure 7As shown in the figure, the first elastic connection component 46 includes a first connection seat 461 provided on the collection box 42 and located below the material taking hopper 44, two first telescopic shafts 462 provided at the bottom of the material taking hopper 44 and passing through the first connection seat 461, and two first return springs 463 sleeved on the first telescopic shafts 462 and with both ends abutted between the first connection seat 461 and the lower surface of the material taking hopper 44. The second elastic connection component includes a second connection seat 471 provided on the collection box 42 and located below the limit retaining seat 45, two second telescopic shafts 472 provided at the bottom of the limit retaining seat 45 and passing through the second connection seat 471, and two second return springs 473 sleeved on the second telescopic shafts 472 and with both ends abutted between the second connection seat 471 and the lower surface of the limit retaining seat 45. The linkage component 48 includes a fixed pulley 481 rotatably connected to the collection box 42, and a cable 482 with both ends connected between the lower ends of the first telescopic shafts 462 and bypassing the fixed pulley 481.

[0034] As shown in 1, Figure 2 , Figure 6 and Figure 7 As shown in the figure, the positioning mechanism 43 includes a positioning block 431 arranged to be lifted and lowered on the base 41, a lifting cylinder 432 arranged between the base 41 and the positioning block 431, and a plurality of positioning sleeves 433 provided in the middle below the collection box 42 for the positioning block 431 to be inserted into, and the opening of the positioning sleeve 433 is arranged to be flared. One side of the collection box 42 has two plug-in sleeves 425 with openings upward, a notch 4251 is arranged on the side of the plug-in sleeve 425 away from the collection box 42, and on the other side of the collection box 42, there are two plug-in parts 426 which are used to be inserted into the adjacent plug-in sleeves 425 of the collection box 42 after being lifted upward. The plug-in part 426 includes a plug-in shaft 4261 arranged on the collection box 42 and inserted into the notch 4251, and a circular plug-in piece 4262 arranged at the end of the plug-in shaft 4261 and inserted into the plug-in sleeve 425.

[0035] Implementation effect: After the sheet material is processed by the blanking punching machine 1 and the rolling machine 2, the rim semi-finished product is pushed into the inclined discharge channel 52 by the push plate 22 of the rolling machine 2. The rim semi-finished product rolls along the inclined discharge channel 52 and falls into the collection box 42 for collection. When the rim semi-finished product rolls in the inclined discharge channel 52, its falling speed is reduced by the speed reduction mechanism 53. At the same time, after a batch of rim semi-finished products are collected in the collection box 42, the collection box 42 can directly move away from the base 41 and the slide rail 411 through the universal wheels 421 at the bottom. The next collection box 42 moves along the slide rail 411 and is positioned by the positioning mechanism 43 to align with the inclined discharge channel 52, so as to continue collecting the rim semi-finished products; finally, it has the function of automatically collecting the rim semi-finished products and facilitating the transfer to the subsequent workstations.

[0036] When the semi-finished rim rolls down along the inclined discharge channel 52, first, the semi-finished rim hits the stop shaft 533 within the first chute portion 53111. The force exerted by the semi-finished rim on the stop shaft 533 can overcome the elastic force of the compression spring 535, causing the stop shaft 533 to move along the first chute portion 53111 and the second chute portion 53112 to the upper end of the second chute portion 53112. During this process, the semi-finished rim can be decelerated and ensured to pass through the stop shaft 533. At the same time, when the stop shaft 533 moves to the upper end of the second chute portion 53112, under the reset action of the compression spring 535, the stop shaft 533 moves along the third chute portion 53112 back into the first chute portion 53111 and resets, realizing the function of automatically decelerating the semi-finished rim when it passes through.

[0037] When taking out the semi-finished rims in the material taking hopper 44 one by one, the circumferences of adjacent semi-finished rims are in contact with the circumference of the semi-finished rim in the material taking hopper 44, and the semi-finished rim on the inclined plate 424 exerts a downward-sloping force on the semi-finished rim in the material taking hopper 44, making it more difficult to take out the semi-finished rims in the material taking hopper 44. At this time, through the lifting setting of the material taking hopper 44 and the settings of the first elastic connection component 46, the second elastic connection component 47, and the linkage component 48, the following motion states are achieved: (1) When there is no semi-finished rim in the material taking hopper 44, the bottom of the material taking hopper 44 and the bottom of the inclined plate 424 are on the same plane, and the limit stop seat 45 does not protrude from the inclined plate 424; (2) During the process that the previous semi-finished rim falls into the material taking hopper 44 and overcomes the elastic force of the first elastic connection component 46, causing the material taking hopper 44 to move downward, the linkage component 48 gradually cancels the downward force on the second elastic component, and the second elastic connection component 47 drives the limit stop seat 45 to move upward to prevent the latter semi-finished rim from passing through the discharge port 423; (3) When the semi-finished rim in the material taking hopper 44 is taken out, the first elastic connection component 46 drives the material taking hopper 44 to reset upward, and the linkage component 48 overcomes the elastic force of the second elastic component to reset the limit stop seat 45; ultimately, it is convenient to take out the semi-finished rims in the material taking hopper 44.

[0038] When the collection box 42 moves into place, the lifting cylinder 432 drives the positioning block 431 to move upward and then embed into the positioning sleeve 433 at the bottom of the collection box 42. Combined with the fact that the collection box 42 is slidably connected to the slide rail 411, the collection box 42 is positioned to align with the inclined discharge channel 52. When the collection box 42 filled with semi-finished rims moves to the next process, one collection box 42 can be lifted upward so that the plug-in part 426 is installed in the plug-in sleeve 425 of another collection box 42, thus facilitating the simultaneous transportation after multiple collection boxes 42 are spliced together. Embodiment 2: A hub plate cutting and bending machine set, such asFigure 8 and Figure 9 As shown in Figure 9 , the difference from Embodiment 1 is that the feeding hopper 44 is arranged to be lifted and lowered on the side of the collection box 42. An elastic intermittent connection assembly 49 is arranged between the bottom of the feeding hopper 44 and the collection box 42, which drives the collection box 42 to move downward after receiving the rim semi-finished product, and first remains fixed and then resets upward when the rim semi-finished product is taken out. A limiting piece 441 is arranged on one side of the feeding hopper 44 close to the collection box 42. When the feeding hopper 44 moves downward to the limit state after receiving the rim semi-finished product, the limiting piece 441 blocks the discharge port 423 to prevent the next rim semi-finished product from passing through the discharge port 423. The elastic intermittent connection assembly 49 includes a third connection seat 491 arranged below the collection box 42, two third telescopic shafts 492 arranged at the bottom of the feeding hopper 44 and passing through the third connection seat 491, two third return springs 493 sleeved on the third telescopic shafts 492 and with both ends abutted between the third connection seat 491 and the lower surface of the feeding hopper 44, a first suction cup 494 arranged below the third telescopic shaft 492, and a second suction cup 495 arranged on the collection box 42 and aligned with the first suction cup 494. When the feeding hopper 44 moves to the limit state after receiving the rim semi-finished product, the first suction cup 494 and the second suction cup 495 are adsorbed to each other. The acting force when the third compression spring 535 resets can overcome the suction force of the first suction cup 494 and the second suction cup 495, so that the first suction cup 494 and the second suction cup 495 can first remain adsorbed and then separate during the reset process of the third compression spring 535.

[0039] Implementation effect: When the rim semi-finished product enters the feeding hopper 44, the overall weight of the feeding hopper 44 increases, thus overcoming the elastic force of the third return spring 493, causing the feeding hopper 44 and the third telescopic shaft 492 to move downward. At this time, the limiting piece 441 on the feeding hopper 44 blocks the discharge port 423 to prevent the next rim semi-finished product from passing through the discharge port 423, and the first suction cup 494 and the second suction cup 495 are adsorbed to each other. When the rim semi-finished product in the feeding hopper 44 is taken out, the third return spring 493 has a tendency to reset. After gradually overcoming the suction force of the first suction cup 494 and the second suction cup 495, the feeding hopper 44 resets, enabling the next rim semi-finished product to move into the feeding hopper 44.
