[0033] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clearly, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0034] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0036] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0037] In the prior art, the feeding assembly on the stamping equipment is usually designed in the form of a plunger and a slider, the plunger is fixedly installed on the upper die, the slider is slidably arranged on the lower die, and the corresponding abutting parts of the plunger and the slider are both provided with inclined surfaces. When the upper die moves downward relative to the lower die, the inclined surface of the plunger abuts against the inclined surface of the slider, thereby pushing the slider to slide in the horizontal direction. When the upper die moves upward relative to the lower die to reset, the slider slides and resets in the horizontal direction relative to the lower die, and the slider pushes the workpiece to the processing station during the sliding reset process. However, the slider is pushed only by the abutment of the inclined surface of the plunger and the inclined surface of the slider, which greatly reduces the sliding stroke of the slider. When the stroke of the upper die relative to the lower die is small, the slider cannot meet the demand for a large stroke of pushing the workpiece, which greatly reduces the scope of application of the stamping equipment.

[0038] In order to solve the above problems, Figure 1 and Figure 2As shown, the stamping equipment provided in this embodiment includes an upper die 1, a lower die 2 and a feeding assembly 3, wherein the lower die 2 is located below the upper die 1, the lower die 2 is used to carry the workpiece 20, and the upper die 1 can be lifted and lowered relative to the lower die 2, the feeding assembly 3 includes a driving member 31 and a feeding member 32, the feeding member 32 is slidably arranged on the lower die 2, the feeding member 32 is used to push the workpiece 20 on the lower die 2 to a processing station, the first end of the driving member 31 is rotatably connected to the upper die 1, and the second end of the driving member 31 is in contact with the feeding member 32, when the upper die 1 descends relative to the lower die 2, the second end of the driving member 31 pushes the feeding member 32 to slide in a direction away from the workpiece 20 (the right direction in the figure). In the stamping equipment provided in this embodiment, when the upper mold 1 descends relative to the lower mold 2, the driving member 31 can rotate relative to the upper mold 1 under the action of the common extrusion force of the upper mold 1 and the feeding member 32, so that the second end of the driving member 31 pushes the feeding member 32 to slide in the direction away from the workpiece 20, so that the feeding member 32 is pushed by the rotation of the driving member 31, and the sliding stroke of the feeding member 32 is effectively increased. Even if the lifting stroke of the upper mold 1 relative to the lower mold 2 is small, the feeding member 32 can also meet the demand for a large pushing stroke of the workpiece 20, which effectively increases the scope of application of the stamping equipment.

[0039] It should be noted that if Figure 2 As shown, when the upper mold 1 rises relative to the lower mold 2, the driving member 31 can rotate in the opposite direction relative to the upper mold 1. At this time, the driving member 31 no longer generates a pushing force on the feeding member 32 away from the workpiece 20. At this time, the feeding member 32 can slide in the direction close to the workpiece 20 (the left side direction in the figure), thereby pushing the workpiece 20 to the processing station.

[0040] It should be noted that in this embodiment, the upper mold 1 can be driven to rise and fall relative to the lower mold 2 by a motor drive assembly, or by a driving cylinder. The specific form of driving the upper mold 1 to rise and fall relative to the lower mold 2 is not limited in this embodiment.

[0041] Optionally, in this embodiment, if Figure 1 and Figure 2 As shown, the feeding assembly 3 further includes a first reset member 33, which is connected between the lower die 2 and the feeding member 32, and is used to drive the feeding member 32 to slide and reset in a direction close to the workpiece 20. When the upper die 1 rises relative to the lower die 2, and the driving member 31 no longer generates a driving force on the feeding member 32 in a direction away from the workpiece 20, the feeding member 32 can slide and reset in a direction close to the workpiece 20 under the action of the first reset member 33.

[0042] Specifically, in this embodiment, the first reset member 33 can be a first reset spring, and the first reset spring is connected between the lower mold 2 and the feed member 32. When the upper mold 1 descends relative to the lower mold 2, the second end of the driving member 31 pushes the feed member 32 to slide toward the right, and the first reset spring is subjected to a tensile force. When the upper mold 1 rises relative to the lower mold 2, the driving member 31 no longer generates a rightward push force on the feed member 32, and the feed member 32 slides toward the left and resets under the action of the elastic restoring force of the first reset spring. Optionally, the first reset spring can be a wire spring, which has the advantages of good elasticity and easy installation.

[0043] Optionally, in this embodiment, a guide post 21 extending in the left-right direction may be fixedly connected to the lower mold 2, the feed piece 32 is slidably sleeved on the guide post 21, and the first return spring is sleeved on the guide post 21. By providing the guide post 21, not only a guide is provided for the sliding of the feed piece 32, but also the positioning installation of the first return spring is realized.

[0044] Optionally, in this embodiment, the driving member 31 is a driving swing rod, the first end (i.e., the upper end) of the driving swing rod is rotatably connected to the upper die 1 through a connecting shaft, and the second end (i.e., the lower end) of the driving swing rod is in contact with the feeding member 32. When the upper die 1 rises to an initial height relative to the lower die 2, the driving swing rod rotates to the left side relative to the upper die 1 around the axis of the connecting shaft to an initial position, and the driving swing rod in the initial position is tilted from top to bottom in a direction away from the workpiece 20. The above arrangement ensures that when the upper die 1 descends relative to the lower die 2, the driving swing rod rotates to the right side around the axis of the connecting shaft under the action of the extrusion force of the upper die 1 and the feeding member 32, thereby ensuring the driving swing rod's pushing effect on the feeding member 32 toward the right side.

[0045] Optionally, in this embodiment, the feeding assembly 3 further includes a stopper 34, which is disposed on the upper mold 1 and can abut against the driving swing arm to limit the driving swing arm to an initial position. By providing the stopper 34, the driving swing arm is prevented from excessively rotating toward the left side during the process of the driving swing arm rotating toward the left side around the axis of the connecting shaft to reset, and the driving swing arm is always in a state of tilting from top to bottom toward the right side, thereby ensuring the driving swing arm's pushing effect on the feeding member 32 toward the right side. Specifically, the stopper 34 can be in the form of a stopper block.

[0046] Optionally, in this embodiment, the feeding assembly 3 further includes a second reset member 35, which is connected between the upper die 1 and the driving swing arm, and is used to drive the driving swing arm to reset to an initial position. By providing the second reset member 35, when the upper die 1 rises relative to the lower die 2, the upper die 1 and the feeding member 32 no longer generate a squeezing force on the driving swing arm, and the driving swing arm can more reliably rotate toward the left side around the axis of the connecting shaft and reset to an initial position under the action of the second reset member 35.

[0047] Specifically, in this embodiment, the second reset member 35 can be a second reset spring, which is connected between the upper die 1 and the driving swing arm. When the upper die 1 descends relative to the lower die 2, the second end of the driving member 31 pushes the feeding member 32 to slide toward the right, and the second reset spring is subjected to a tensile force. When the upper die 1 rises relative to the lower die 2, the upper die 1 and the feeding member 32 no longer exert a squeezing force on the driving swing arm. At this time, the driving swing arm rotates toward the left side around the axis of the connecting shaft more reliably and resets to the initial position under the action of the elastic restoring force of the second reset spring. Optionally, the second reset spring can be a tension spring, which has the advantages of good elasticity and easy installation.

[0048] It should be noted that in other embodiments, the second reset member 35 may not be provided. When the upper mold 1 rises relative to the lower mold 2, the driving rocker arm can also rotate toward the left side around the axis of the connecting shaft under the action of its own gravity and reset to the initial position.

[0049] Optionally, in this embodiment, the second end of the driving swing arm is arc-shaped. By designing the second end of the driving swing arm to be arc-shaped, when the second end of the driving swing arm drives the feeding member 32 to slide, the damage caused by the driving swing arm and the feeding member 32 pressing against each other is reduced, thereby improving the protection of the feeding member 32 and the driving swing arm.

[0050] Optionally, in this embodiment, the feeding member 32 is a feeding slider, which includes a sliding portion 321 and an abutting portion 322 connected at an angle, wherein the sliding portion 321 is slidably arranged on the lower die 2 and can abut against the workpiece 20, and the second end of the driving rocker can abut against the sliding portion 321 and the abutting portion 322 at the same time. The above arrangement effectively increases the abutment area of ​​the driving rocker and the feeding slider, and improves the stability and reliability of the driving rocker pushing the feeding slider.

[0051] Specifically, in this embodiment, the sliding portion 321 includes an abutting bottom wall 3211, and the abutting portion 322 includes an abutting side wall 3221. The abutting bottom wall 3211 and the abutting side wall 3221 are connected at an angle, and the second end of the driving swing rod can abut against the abutting bottom wall 3211 and the abutting side wall 3221 at the same time, further improving the stability and reliability of the driving swing rod pushing the feeding slide block. Optionally, the abutting bottom wall 3211 and the abutting side wall 3221 are connected in a smooth transition, so that the structure is more beautiful.

[0052] Optionally, in this embodiment, if Figure 2 As shown, when the upper mold 1 rises to the initial height relative to the lower mold 2, the second end of the driving rocker only abuts against the upper end of the abutting side wall 3221. As the upper mold 1 descends, the second end of the driving rocker moves downward along the abutting side wall 3221 until it abuts against the abutting bottom wall 3211. At this time, when the upper mold 1 continues to descend, the second end of the driving rocker can push the feeding slide block to slide to the right. The above arrangement effectively ensures the reliability of the abutment between the driving rocker and the feeding slide block.

[0053] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
