Description

Technical Field

[0001] This utility model generally relates to the technical field of machining, and more specifically to a punch unloading device and a punch. Background Technology

[0002] Currently, waste removal from existing punch presses is generally achieved manually, by cylinder, or by other power assistance, which results in high processing costs, a tendency to malfunction, and insufficient production efficiency. Utility Model Content

[0003] The utility model description section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description section is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0004] To at least partially solve the above problems, the first aspect of this utility model provides a discharge device for a punch press, the discharge device comprising:

[0007] The material feeding assembly is disposed below the working surface of the lower mold. The material feeding assembly includes an elastic element that is deformed by the pressure of the upper mold located at the mold closing position. The elastic element is used to rotate the material residue between the upper mold and the lower mold that has disengaged from the mold closing position toward the outside of the lower mold using the deformation restoring force.

[0008] According to the unloading device of the punch press according to the first aspect of the present invention, when the upper die moves to the die-closing position, the upper die moves at least partially below the working surface of the lower die, thereby realizing the processing of the material. At this time, the material residue separated by the processing is located between the upper die and the unloading assembly. The upper die in the die-closing position squeezes the elastic element, causing the elastic element to deform. When the upper die moves to the demolding position, the elastic element drives the material to rotate, causing the material residue to be thrown outward toward the lower die. This realizes the automatic unloading of the material residue, eliminating the need for manual unloading or the use of an additional drive source to unload the material residue, reducing the processing cost of the punch press, increasing production efficiency, and reducing the failure rate.

[0009] Optionally, the feeding assembly further includes a fixing plate and a throwing plate. The fixing plate is disposed on the lower mold. The first end of the elastic element is connected to the throwing plate, and the second end of the elastic element is connected to the fixing plate. The throwing plate is used to abut against the material.

[0010] Optionally, the lower mold is provided with an inclined surface, which is located below the working surface. The inclined surface is inclined toward the side of the lower mold from which the material is discharged, so that the inclined surface has a first angle with the horizontal plane perpendicular to the height direction.

[0011] Optionally, the lower mold is provided with a receiving groove, the receiving groove is in communication with the inclined surface, and the feeding assembly is at least partially located in the receiving groove.

[0012] Optionally, the receiving groove includes a first groove and a second groove, the second groove being arranged above the first groove along the height direction and communicating with the inclined surface; the fixing plate is disposed in the first groove, and the elastic element is at least partially located in the second groove.

[0013] Optionally, when the upper mold is in the mold closing position, the ejector plate enters the second groove under the abutment of the remaining material.

[0014] Optionally, the ejector plate is movably disposed relative to the lower mold between a retracted position and an ejected position via the elastic element; the ejector plate in the ejected position is closer to the side of the lower mold from which the material is discharged, relative to the ejector plate in the retracted position.

[0015] Optionally, a second included angle is formed between the ejector plate located at the retracted position and the ejected position, the second included angle being no less than the first included angle.

[0016] Optionally, the end of the ejector plate away from the lower mold on the side where the material is discharged is configured to form a guide arc surface.

[0017] A second aspect of this utility model provides a punch press, including a material unloading device according to the above-described punch press.

[0018] According to the punch press of the second aspect of this utility model, automatic unloading of material scrap is realized, eliminating the need for manual unloading or the use of an additional drive source to unload material scrap, resulting in low processing cost, high production efficiency, and low failure rate.

However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the present invention.

[0034] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0035] Unless otherwise stated, the numerical ranges in this document include not only the entire range within its two endpoints, but also the subranges contained therein.

[0036] This utility model provides a punch press, which includes a material unloading device 100 and a drive mechanism, as shown in the reference. Figure 1 and Figure 2 The unloading device 100 includes an upper mold 120 and a lower mold 110. The top surface of the lower mold 110 is configured as a working surface 115. During processing, the material is clamped and fixed on the working surface 115. Then, a drive mechanism (e.g., a hydraulic cylinder) drives the upper mold 120 from the demolding position to the mold closing position, causing the bottom surface of the upper mold 120 to move below the working surface 115 (along the height direction D1 of the unloading device 100), thereby realizing the processing of the material. For example... Figure 1 As shown, before the upper mold 120 moves to the demolding position, the residual material generated after processing is located between the upper mold 120 and the lower mold 110. This residual material 140 needs to be unloaded so as not to affect the subsequent processing of materials.

[0037] In existing technologies, manual or additional drive sources are generally used to unload the remaining material 140, resulting in low processing efficiency and high processing costs for the punch press. Furthermore, using additional drive sources increases the failure rate of the punch press and makes it difficult to control.

[0038] Therefore, this utility model provides a punch press unloading device 100, referring to... Figure 1 and Figure 2 The unloading device 100 includes a lower mold 110, an upper mold 120, and an unloading assembly 130. The lower mold 110 is provided with a working surface 115. The upper mold 120 is movably disposed relative to the lower mold 110 along the height direction D1 of the unloading device 100 between a mold-closing position and a mold-demolding position. When in the mold-closing position, the upper mold 120 is at least partially moved below the working surface 115 to process the material.

[0039] The feeding assembly 130 is located below the working surface 115 of the lower mold 110. The feeding assembly 130 includes an elastic element 131. The elastic element 131 is deformed by the pressure of the upper mold 120 located in the mold closing position, and the deformation recovery force is used to drive the material residue 140 between the upper mold 120 and the lower mold 110, which is out of the mold closing position, to rotate towards the outside of the lower mold 110.

[0040] According to the unloading device 100 of the punch press of this utility model, when the upper die 120 moves to the die-closing position, the upper die 120 moves at least partially below the working surface 115 of the lower die 110, thereby realizing the processing of the material. At this time, the processed and separated material residue 140 is located between the upper die 120 and the unloading assembly 130. The upper die 120 in the die-closing position squeezes the elastic element 131, causing the elastic element 131 to deform. When the upper die 120 moves to the demolding position, the elastic element 131 drives the material to rotate, causing the material residue 140 to be thrown outward toward the lower die 110. This realizes the automatic unloading of the material residue 140, eliminating the need for manual unloading or the use of an additional drive source to unload the material residue 140, reducing the processing cost of the punch press, increasing production efficiency, and reducing the failure rate.

[0041] Reference Figure 2 The unloading assembly 130 also includes a fixed plate 132 and a ejector plate 133. The fixed plate 132 is disposed on the lower mold 110. The first end of the elastic element 131 is connected to the ejector plate 133, and the second end of the elastic element 131 is connected to the fixed plate 132. The ejector plate 133 is used to abut against the material. During the process of the upper mold 120 moving from the demolding position to the mold closing position, the bottom surface of the upper mold 120 drives the remaining material 140 to gradually abut against the ejector plate 133, and brings the ejector plate 133 closer to the fixed plate 132. At this time, the elastic element 131 deforms. When the upper mold 120 moves to the demolding position, the elastic element 131 restores its deformation, thereby driving the ejector plate 133 to rotate towards the outside of the lower mold 110, so that the remaining material 140 is driven by the ejector plate 133 to the outside of the lower mold 110, realizing automatic unloading.

[0042] Optionally, refer to Figure 1 and Figure 2 The lower mold 110 is provided with an inclined surface 111. The inclined surface 111 is arranged along the horizontal direction D2 on the side of the working surface 115 near the unloading component 130, and the inclined surface 111 is arranged below the working surface 115, thereby providing space for the upper mold 120 to move to the mold closing position and realize the processing of materials.

[0043] The inclined surface 111 is inclined toward the side of the lower mold 110 where the material is discharged, so that the inclined surface 111 has a first angle a1 with the horizontal plane perpendicular to the height direction D1, so that when the material residue 140 falls on the inclined surface 111, it can slide off the lower mold 110 along the inclined surface 111, thus realizing the smooth unloading of the material residue 140.

[0044] Optionally, refer to Figure 1 and Figure 2The ejector plate 133 is movably disposed relative to the lower mold 110 between a retracted position and an ejected position via the elastic element 131. Specifically, the ejector plate 133 is rotatably connected to the lower mold 110 via the elastic element 131. The ejector plate 133 in the ejected position is closer to the side of the lower mold 110 where the material is discharged, relative to the ejector plate 133 in the retracted position, thereby allowing the ejector plate 133 to drive the remaining material 140 to the outside of the lower mold 110.

[0045] Optionally, combined Figure 2 As shown, there is a second included angle a2 between the throwing plate 133 located in the retracted position and the ejected position. The second included angle a2 is not less than the first included angle a1, so that the throwing plate 133 has a sufficient tilt angle when it is in the ejected position, which improves the success rate of unloading and thus achieves unloading smoothly.

[0046] Optionally, the end of the ejector plate 133 away from the material discharge side of the lower die 110 is configured to form a guide arc surface 134, thereby reducing wear when the ejector plate 133 contacts the material residue 140, and also reducing the noise generated by the ejector plate 133 contacting the material residue 140 during the punching process.

[0047] Optionally, refer to Figure 1 and Figure 2 The lower die 110 is provided with a receiving groove 112, which is connected to the inclined surface 111. The blanking component 130 is at least partially located in the receiving groove 112. The height of the blanking component 130 protruding from the inclined surface 111 can be shortened along the height direction D1, so as not to limit the height dimension of the punch press. This also makes the installation between the blanking component 130 and the lower die 110 more compact and safer for manual operation.

[0048] Optionally, the receiving groove 112 includes a first groove 113 and a second groove 114. The second groove 114 is arranged above the first groove 113 along the height direction D1 and communicates with the inclined surface 111. The fixing plate 132 is disposed in the first groove 113, and the elastic element 131 is at least partially located in the second groove 114, thereby realizing the reception and installation of the fixing plate 132 and the elastic element 131.

[0049] Optionally, when the upper mold 120 is in the mold-closed position, the ejector plate 133 enters the second groove 114 under the action of the material, so that the unloading assembly 130 can be completely entered into the receiving groove 112.

[0050] Optionally, the elastic element 131 can be a torsion spring, which has a simple structure, stable transmission, and can rotate to drive the throwing plate 133.

[0051] This utility model also provides a punch press, including a material unloading device 100 according to the above-described punch press. The punch press according to this utility model achieves automatic unloading of the material scrap 140, eliminating the need for manual unloading or the use of an additional drive source to unload the material scrap 140, resulting in low processing costs, high production efficiency, and low failure rate.
