[0036] In a specific embodiment of the present invention, Figure 1 , 2 As shown in Figure 5, the swing assembly includes a swing plate 400 and a power mechanism for driving the swing plate 400 to swing, the power mechanism includes a first motor 500, a driving gear 600 and a driven gear 700, the driven gear 700 is fixedly connected to one end of the swing plate 400, the driven gear 700 is rotatably connected to the workbench 100 (a vertical rod is fixed on the workbench 100, a first elastic retaining ring is installed on the vertical rod, the driven gear 700 is rotatably sleeved on the vertical rod and is located between the first elastic retaining ring and the workbench 100), the swing range of the swing plate 400 is greater than and covers the positioning groove 110, ensuring that the swing plate 400 can push the bracket 300 on the positioning groove 110 out of the positioning groove 110; the first motor 500 is fixedly connected to the workbench 100, the output shaft of the first motor 500 is fixedly connected to the driving gear 600, the driving gear 600 is meshed with the driven gear 700, and the driving gear 600 is located on the side of the driven gear 700 away from the positioning groove 110. The power mechanism may also be other mechanisms in the prior art, such as driving the swing plate 400 to swing through a cylinder or driving the swing plate 400 to swing through a connecting rod mechanism, and the swing plate 400 is equivalent to a rocker rod.

[0037] In a specific embodiment of the present invention, Figure 3 , 4 As shown in Figure 6, the limit assembly includes two symmetrically arranged limit brackets 800, and the opposite sides of the two limit brackets 800 are provided with limit grooves matching the two ends of the bracket plate 200; the limit bracket 800 is fixedly connected to the workbench 100, and the distance from the bottom end surface of the limit bracket 800 to the bottom wall of the slide groove 120 matches the thickness of the bracket plate 200.

[0038] In a specific embodiment of the present invention, Figures 1 to 7 As shown, the pusher assembly includes a push plate 900 and a transmission mechanism. The push plate 900 is arranged between the slide groove 120 and the limit assembly. The push plate 900 is slidably connected to the bottom wall of the slide groove 120. The transmission mechanism is installed on the bottom surface of the workbench 100, and the transmission mechanism is transmission-connected to the push plate 900.

[0039] In a specific embodiment of the present invention, Figure 1 and 4 As shown in Figures 1 to 7, two slide rails 910 are fixed symmetrically on the bottom surface of the push plate 900, and a slideway corresponding to the slide rails 910 is opened on the bottom wall of the slide groove 120. The slideway is slidably connected with the slide rails 910 to ensure the stability and linearity of the push plate 900 during movement. The cross-sections of the slide rails 910 and the slide groove 120 are dovetail-shaped or T-shaped.

[0040] In a specific embodiment of the present invention, the vertical distance between the top surface of the push plate 900 and the bottom end of the limit assembly is greater than zero. When the push plate 900 pushes the bracket plate 200 at the bottom, it can prevent the push plate 900 from rubbing against the bracket plate 200 above, reduce the probability of the push plate 900 being worn, extend the service life of the push plate 900, and reduce the resistance of the transmission mechanism driving the push plate 900. The distance between the bottom surface of the push plate 900 and the bottom wall of the slide groove 120 is greater than or equal to zero, avoids or reduces the friction between the push plate 900 and the slide groove 120, extends the service life of the push plate 900, and reduces the resistance of the transmission mechanism driving the push plate 900. The depth of the slide groove 120 matches the thickness of the bracket plate 200, ensuring that the push plate 900 can only push the bracket plate 200 in contact with the slide groove 120, and the other bracket plates 200 are still limited by the limit groove of the limit bracket 800 and cannot be displaced, ensuring that one bracket plate 200 is pushed at a time.

When the bracket plate 200 in contact with the slide groove 120 is pushed out (not located under other bracket plates 200), other bracket plates 200 are supported on the rotating shaft 920 to avoid friction between other bracket plates 200 and the push plate 900.

[0042] In a specific embodiment of the present invention, Figures 4 to 7 As shown, the transmission mechanism includes a second motor 1000 and a driving gear 1100, a pair of vertical plates are fixed to the bottom surface of the workbench 100, a support shaft is rotatably mounted between the two vertical plates, and the driving gear 1100 is fixedly connected to the support shaft (a second elastic retaining ring corresponding to the vertical plates is installed on the support shaft, and the second elastic retaining ring is located between the two vertical plates and is rotatably contacted with the vertical plates; the support shaft is connected to the driving gear 1100 through a key, and a third elastic retaining ring is installed on the support shaft and is contacted with both sides of the driving gear 1100), the second motor 1000 is fixedly connected to any vertical plate, and the output shaft of the second motor 1000 is fixedly connected to one end of the support shaft; a rack 930 is fixed under the push plate 900 (two connecting plates are fixed to the bottom surface of the push plate 900, a rack 930 is fixed between the two connecting plates, and the rack 930 is located under the rotating shaft 920), and the rack 930 is meshed with the driving gear 1100. The transmission mechanism can also be in other forms, such as driving the push plate 900 to move through a cylinder or driving the push plate 900 to move through a connecting rod slider mechanism, and the push plate 900 is equivalent to a slider.

[0043] In a specific embodiment of the present invention, Figures 1 to 4As shown in FIG. 6 , arc plates 1200 for guiding the bracket 300 are respectively arranged on both sides of the positioning groove 110. The arc plates 1200 are fixedly connected to the workbench 100. The center of the arc plates 1200 coincides with the driven gear 700. The radius of the arc plates 1200 is greater than or equal to the length of the swing plate 400. When the swing plate 400 pushes the bracket 300 out of the positioning groove 110, the arc plates 1200 guide and limit the bracket 300 so that it is pushed to the end of the workbench 100 away from the material pushing assembly, and the material unloading is completed. Then the staff can collect the bracket 300.

[0044] The working process of a caster bracket production device of the present invention is as follows:

[0045] In general, the caster bracket production device uses the workbench 100 as the basic bearing structure, and each component works together to realize the automated production process of the caster bracket. First, multiple bracket plates 200 are stacked up, and the stacked bracket plates 200 are placed on the top of two limit brackets 800. The bracket plates 200 fall onto the slide 120 under the action of gravity, and the limit grooves of the limit bracket 800 limit the two ends of the bracket plate 200 located between the two limit brackets 800. The pushing component pushes the bracket plate 200 in contact with the slide 120 to the positioning groove 110 to complete the loading. The stamping component performs a stamping and bending operation on the bracket plate 200 in the positioning groove 110. The swinging component pushes the stamped and bent bracket 300 out of the positioning groove 110, and completes the unloading under the guidance of the arc plate 1200, which is convenient for the staff to collect.

[0046] The push plate 900 is located on the side of the bracket plate 200 away from the positioning groove 110. The second motor 1000 drives the driving gear 1100 to rotate through the support shaft. The driving gear 1100 drives the push plate 900 to slide on the slide groove 120 through the rack 930. The push plate 900 pushes the bracket plate 200 in contact with the slide groove 120. The upper bracket plate 200 cannot be displaced due to the limiting groove of the limiting bracket 800, thereby ensuring a single push of one bracket plate 200. When the bracket plate 200 is pushed into the positioning groove 110, one loading is completed, and the second motor 1000 reverses to reset the push plate 900 and prepare for the next loading. During the resetting process, the bracket plate 200 in the limit bracket 800 rolls in contact with the rotating shaft 920. When the rotating shaft 920 moves away from the bracket plate 200, the bracket plate 200 falls on the push plate 900. When the push plate 900 completes the resetting, the bracket plate 200 falls on the slide groove 120 under the action of gravity, and the bracket plate 200 at the bottom becomes the new bracket plate 200 in contact with the slide groove 120.

[0047] After the stamping and the push plate 900 is reset, the telescopic rod of the telescopic cylinder 1500 is extended and drives the mounting plate and the upper die 1300 to move downward. The upper die 1300 cooperates with the lower die 1400 to stamp and bend the bracket plate 200 in the positioning groove 110. At the same time, the movable top block 1600 is pressed onto the bottom wall of the mold cavity of the lower die 1400, and the tension spring 1700 is stretched. Then the telescopic rod contracts, the upper die 1300 rises, and the tension spring 1700 pulls the fixed plate 1800 upward. The fixed plate 1800 drives the movable top block 1600 to move upward through the slide bar 1900, and the movable top block 1600 ejects the bent bracket 300 from the mold cavity of the lower die 1400.

[0048] The swing assembly starts the first motor 500, the first motor 500 drives the driving gear 600 to rotate, the driving gear 600 drives the driven gear 700 to rotate, the driven gear 700 drives the swing plate 400 to swing, and the bracket 300 moves to the end of the workbench 100 away from the push assembly under the push of the swing plate 400. In this process, the arc plate 1200 guides and limits the bracket 300, so that the bracket 300 moves along the arc direction of the arc plate 1200 to prevent the bracket 300 from being scattered randomly during the unloading process, and finally being pushed out of the positioning groove 110, completing the unloading, which is convenient for the staff to collect. When unloading the next bracket 300, the first motor 500 is reversed.

[0049] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other, and the embodiments can be combined with each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.

[0050] The above embodiments are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
