The utility model may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present utility model. It should be understood that the preferred embodiments are presented by way of illustration only and not by way of limitation.

It should be noted that the illustrations provided in the following embodiments merely illustrate the basic concept of the present utility model by way of illustration, and only the components related to the present utility model are shown in the drawings and are not drawn according to the number, shape and size of the components in actual implementation, and the form, number and proportion of the components in actual implementation may be arbitrarily changed, and the layout of the components may be more complicated.

In the related art, when the fender performs peripheral trimming, the waste material knife process at the hub generally adopts a knife back to knife back mode to cut off the waste material, and then the waste material is ejected out by adopting an air cylinder. As shown in fig. 1, fig. 1 is a schematic diagram of a structure of a related art when trimming a fender 010, and in the process of manufacturing the fender 010, it is necessary to cut off a scrap 011 of the fender 010 by a scrap cutter, and finally, a process product 012 is obtained.

After the scrap 011 is cut off using a scrap cutter, the scrap 011 needs to be ejected by a cylinder or the like. However, as shown in fig. 2, fig. 2 is a partially enlarged view of fig. 1, since the cutting line 013 of the scrap 011 is abutted against the process product 012, the process product 012 is easily displaced during ejection of the scrap 011, and thus the positioning and accuracy of the process product 012 are affected.

Based on this, the embodiment of the present application provides a fender processing apparatus, as shown in fig. 3, fig. 3 is a schematic partial structure diagram of a fender processing apparatus 100 provided in the embodiment of the present application, where the fender processing apparatus 100 may include an upper die holder (not shown in the figure), a lower die holder (not shown in the figure), and a fender die 10. The upper die holder and the lower die holder can be used for fixing related components of the fender processing device 100 and processing and manufacturing the fender.

Next, a fender mold 10 provided in the embodiment of the present application will be described. As shown in fig. 3, fender mold 10 may include a punch 20 and a first trim 30. Wherein, the male die 20 is mounted on the lower die holder, and a concave portion 201 is formed at one side. The male mold 20 can be used to make the forming process product to complete the fender manufacturing.

First edger 30 is mounted to the lower die base within recess 201. First edger 30 is formed with a first cut portion 301 and a first shrink portion 302. The first constriction 302 forms a first constriction line opening towards the side remote from the recess 201. The first cutting portion 301 is located on a side of the first constriction portion 302 close to the outline of the first recess portion 201, and is disposed around the first constriction portion 302, forming a first cutting line with an opening facing away from the recess portion 201. That is, as shown in fig. 3, the first cut portion 301 and the first constricted portion 302 enclose a non-closed shape having an opening, and trimming can be performed on the side of the fender.

Accordingly, as shown in fig. 4, fig. 4 is a schematic structural view of a second trimming member 40 according to an embodiment of the present application, and the fender mold further includes the second trimming member 40. The second trimming member 40 is mounted on the upper die base, and a second cutting portion 421 and a second shrinking portion 422 are formed. The second constriction 422 forms a second constriction line with an opening. The second cutting portion 421 forms a second cutting line having an opening. The second cut portion 421 is disposed around the periphery of the second contracted portion 422, and the opening of the second cut line is oriented the same as the opening of the second contracted line. That is, as shown in fig. 4, the second cut portion 421 and the second constricted portion 422 also enclose a non-closed shape having an opening.

During trimming of the fender, first and second trimmers 30 and 40 may be located on either side of the fender. In this way, the second cut portion 421 may be located on both sides of the fender panel 50 with the first cut portion 301, and abut against the opposite positions of both sides of the fender panel. Thus, as shown in fig. 5, fig. 5 is a schematic structural diagram of trimming a fender 50 according to an embodiment of the present application, and a scrap 51 of the fender 50 may be separated from a process product 52 along a cutting line 501.

Meanwhile, since the first trimming member 30 is formed with the first shrinkage portion 302 and the second trimming member 40 is formed with the second shrinkage portion 422, the first shrinkage portion 302 and the second shrinkage portion 422 may be located at opposite sides of the fender 50 to exert force on the fender 50 during trimming of the fender 50, and at this time, as shown in fig. 6, fig. 6 is a partially enlarged view of fig. 5, shrinkage lines 502 are formed on the scrap 51 by the action of the first shrinkage portion 302 (fig. 3) and the second shrinkage portion 422 (fig. 4). It will be appreciated that the contraction wire 502 is the position corresponding to the cut position of the scrap 51 after the scrap 51 has been subjected to the first contraction 302 (fig. 3) and the second contraction 422 (fig. 4).

Since the first cutting portion 301 is located at a side of the first shrinkage portion 302 near the contour of the first recess portion 201, the cutting position of the scrap 51 is displaced in a direction away from the process product 52 during the process of cutting the fender 50, and is separated from the process product 52. In this way, when the waste 51 is ejected, the waste 51 and the process product 52 are separated from each other, so that the waste 51 does not drive the process product 52 to displace during the ejection process, thereby ensuring the positioning and the precision of the process product 52.

It will be appreciated that the first constriction 302 and the second constriction 422, when acting on the scrap 51, deform the scrap 51 so that the cutting position of the scrap 51 is displaced away from the process product 52 and separated from the process product 52.

Based on this, the fender mold 10 provided in the embodiments of the present application, the male mold 20 may be used to assist in making the process product 52 of the fender 50. Since first and second edgers 30 and 40 are formed with first and second cut portions 301 and 421 having openings, respectively. When trimming the fender 50, the first and second cutting portions 301 and 421 may be located at opposite sides of the fender 50, and the fender 50 may be cut such that the scrap 51 of the fender 50 may be cut from one side edge of the fender 50.

Meanwhile, since first and second edgers 30 and 40 are further formed with first and second constricted portions 302 and 422, respectively, having openings, and first cut portion 301 is located at a side of first constricted portion 302 near the outline of concave portion 201. Thus, when trimming the fender 50, the first shrinkage portion 302 and the second shrinkage portion 422 can exert force on the waste material 51 of the fender 50, so that the fender 50 is deformed, the cutting position of the waste material 51 is displaced in a direction away from the process product 52, the waste material 51 and the process product 52 are separated from each other, and finally the waste material 51 can not drive the process product 52 to displace in the ejection process, so that the positioning and the precision of the process product 52 are ensured.

As shown in fig. 3, in order to eject the scrap 51, the fender processing apparatus 100 further includes an ejector 60, and the ejector 60 is mounted on the lower die holder. The ejector 60 may be used to eject the scrap 51 (fig. 5). The specific type of the ejector 60 may be selected according to actual circumstances, and the ejector 60 may be an air cylinder as an example.

To enable the first and second constrictions 302, 422 to deform the waste 51, in some embodiments, one of the first and second constrictions 302, 422 may be a groove and the other may be a bead. Based on this, when trimming the fender 50, the first constricted portion 302 and the second constricted portion 422 may approach from both sides of the fender 50 and contact the relative positions of both sides of the fender 50, respectively. In this way, under the action of the first contraction portion 302 and the second contraction portion 422, as shown in fig. 6, the surface of the waste material 51 is formed with the concave area 503, so that the cutting position of the waste material 51 is displaced in the direction away from the process product 52, the cutting position is contracted to the contraction line 502, and finally the waste material 51 and the process product 52 are separated from each other, thereby avoiding displacement of the process product 52.

Of course, in other embodiments, the first constriction 302 and the second constriction 422 can each be ribs. At this time, when trimming the fender 50, the first and second constricted portions 302 and 422 come close to and contact both sides of the fender 50 from both sides of the fender 50, respectively, and the first and second constricted portions 302 and 422 may be located at positions offset from each other on both sides of the fender 50. In this way, the waste material 51 of the fender 50 can also deform under the action of the first contraction part 302 and the second contraction part 422, so that the cutting position of the waste material 51 is displaced towards the direction away from the process product 52, the cutting position is contracted, and finally the waste material 51 and the process product 52 are separated from each other, and the displacement of the process product 52 is avoided.

In some embodiments, the first constriction 302 can be a groove and the second constriction 422 can be a bead. In this way, when trimming the fender 50, the second shrinkage portion 422 can exert a force on the waste material 51 of the fender 50, so that the waste material 51 of the fender 50 is recessed toward the side where the first trimming member 30 is located, and the cutting position of the waste material 51 is displaced in a direction away from the process product 52, so as to separate the waste material 51 from the process product 52.

Of course, in other embodiments, the first constriction 302 may be a bead and the second constriction 422 may be a groove. In this way, when trimming the fender 50, the first shrinkage portion 302 can exert a force on the waste material 51 of the fender 50, so that the waste material 51 of the fender 50 is recessed toward the side where the second trimming member 40 is located, and the cutting position of the waste material 51 is displaced in a direction away from the process product 52, so as to separate the waste material 51 from the process product 52.

In some embodiments, the profile of the cross-sectional shape of the grooves and ribs may be arcuate. Thus, the profile of the cross section of the groove and the convex rib is arc-shaped, so that the groove and the convex rib can be matched more easily, the waste 51 can be extruded more easily, the cutting position of the waste 51 is contracted, and the waste 51 and the process product 52 are separated from each other. Of course, the profile of the cross section shape of the groove and the rib may be other shapes, and may be specifically set according to practical situations, so long as the surface of the waste material 51 is deformed, and the cutting position is ensured to be able to contract.

In some embodiments, as shown in fig. 3, first edger 30 may include a lower edging insert 31 and two scrap knives 32. The lower trimming insert 31 may be mounted to a lower die holder, and is formed with a first sub-cutting portion 311 and a first sub-shrinking portion 312. The two scrap cutters 32 are mounted on the lower die holder on the side of the lower trimming insert 31 away from the contour of the recess 201 and are disposed in spaced relation. The two scrap blades 32 are respectively formed with a second sub-cutting portion 321 and a second sub-contracting portion 322.

The two ends of the first sub-cutting portion 311 are respectively connected with two second sub-cutting portions 321 to form a first cutting portion 301. The two ends of the first sub-constriction 312 are respectively connected with two second sub-constriction 322 to form the first constriction 302. In this way, the first constricted portion 302 and the first cut portion 301 can be formed more conveniently by the cooperation of the two scrap blades 32 and the lower trimming insert 31. Illustratively, as shown in FIG. 3, the recess 201 may be arcuate in shape. Meanwhile, the lower trimming insert 31 may be curved in shape correspondingly and disposed at the contour position of the recess 201.

In some embodiments, as shown in fig. 3, the spacing between the ends of the two scrap blades 32 distal from the lower trimming insert 31 is less than the spacing between the ends of the two scrap blades 32 proximal to the lower trimming insert 31. Thus, based on the scheme shown in fig. 3, as shown in fig. 6, the scrap 51 cut out from the fender 50 is substantially fan-shaped. It will be appreciated that the shape of the cut scrap 51 on the fender 50 may be adjusted according to the actual requirements, i.e. the relative positions of the two scrap cutters 32 may be adjusted according to the actual conditions.

In some embodiments, as shown in fig. 4, second edger 40 may include a body portion 41 and an edging portion 42. The trimming portion 42 is located on one side of the main body 41 and is connected to the main body 41. The trimming portion 42 is formed with a second constricted portion 422 and a second cut portion 421 at an end thereof remote from the main body portion 41. Therefore, the second shrinking portion 422 and the second cutting portion 421 can be formed on the second trimming member 40 more conveniently by the trimming portion 42, and the manufacturing is more convenient.

Next, an exemplary trimming process of the fender 50 will be described. In trimming the fender 50, the second trimming member 40 on the upper die holder gradually approaches the first trimming member 30 of the lower die holder, and the first cutting portion 301 of the first trimming member 30 and the second cutting portion 421 of the second trimming member 40 may contact the two sides of the fender 50 first, so as to cut the fender 50. Second trimming member 40 on the upper die base then continues to be adjacent first trimming member 30 on the lower die base. The first shrinkage part 302 on the first trimming member 30 and the second shrinkage part 422 on the second trimming member 40 respectively abut against two sides of the waste material 51, so that the cutting position of the waste material 51 is shrunk in a direction away from the process product 52, and the waste material 51 and the process product 52 are separated from each other, so that the waste material 51 does not influence the process product 52 in the subsequent ejection process, and the positioning and the precision of the process product 52 are ensured.

The above embodiments are merely preferred embodiments for fully explaining the present utility model, and the scope of the present utility model is not limited thereto. Equivalent substitutions and modifications will occur to those skilled in the art based on the present utility model, and are intended to be within the scope of the present utility model.
