Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing mold technology, specifically relating to an automated processing mold for a rear transverse reinforcing plate. Background Technology

[0002] Stamping is a crucial step in automobile production, relying on presses and dies to apply pressure to various sheet metals, causing them to deform or separate, thus obtaining workpieces of the required shape and size. Stamping is the first process in automobile parts manufacturing. The sheet metal to be processed needs to undergo initial stamping to form trimmed edges. After trimming, the sheet metal is shaped to initially form the structural shape of the part. Then, it undergoes trimming and punching to remove excess edges and corners. After trimming, punching is performed to create through holes at fixed positions on the part, ultimately obtaining the part that meets the standard requirements.

[0003] The stamping processes described above need to be completed on different dies. After each process is completed, the semi-finished product needs to be transferred to the die for the next process to continue stamping until the final part product that meets the standard is obtained. The above processes are currently single-process operations, that is, the dies for each process are not connected. Therefore, it is necessary to manually feed the material for each process. In other words, after completing one process, the semi-finished product needs to be manually transferred to the next process. The whole process requires a lot of manual operation and has very low processing efficiency. Utility Model Content

[0004] This utility model provides an automated processing mold for a rear transverse reinforcing plate. The mold is an integrated mold, which integrates the molds for the floating material, forming, trimming and punching processes of the part stamping process onto a single template. On the same template, the transfer of the material sheet between the molds on the template is completed by using sensor monitoring and equal-interval feeding of the feeding mechanism until the final product is output from the template outlet. The whole process saves most of the manual transfer operation, saves labor costs and improves processing efficiency.

[0005] To achieve the above-mentioned technical objectives, this utility model is implemented through the following technical solution:

[0008] A material floating mechanism is provided on the upper surface of the upper mold frame and near the material feeding side. The material floating mechanism is used to lift the material sheet after stamping.

[0009] The next step of the floating material mechanism is to set a drilling mold, which is used to drill holes in the material sheet under the stamping of the machine.

[0010] The next step after the drilling mold is to set a forming mold, which is used to form the material sheet into the structural shape of the part under the stamping of the machine, so as to obtain a semi-finished part.

[0019] The embedded base and the upper mold frame have a telescopic column insertion groove; the upper opening of the telescopic column insertion groove is opened on the upper surface of the embedded base.

[0020] The telescopic column is placed in the groove and a nitrogen telescopic column is provided. A floating material top rod is provided at the upper end of the nitrogen telescopic column.

[0021] The upper end of the floating material top rod is located at the center of the bottom surface of the floating material block;

[0022] Driven by a nitrogen-filled telescopic column, the floating block can be raised to float the material pieces on it.

[0023] Preferably, the shape of one side of the floating block is formed according to the arc-shaped edge shape and direction of the rear transverse reinforcing plate;

[0024] In addition to lifting floating materials, the floating material block can also be used to directly stamp one side of the material sheet to form an arc edge shape that matches the arc edge of the floating material block.

[0025] Preferably, the drilling molds are arranged in two sets in a mirror-symmetrical manner;

[0026] The drilling mold has through holes of the same shape and size as the holes on the rear transverse reinforcing plate.

[0027] After the sheet material is stamped on the punching die, holes are formed on the sheet material.

[0028] Preferably, the forming mold includes a primary forming mold and a secondary forming mold; the sheet material needs to be stamped on the primary forming mold and the secondary forming mold in sequence to form a semi-finished part;

[0029] Both the primary molding die and the secondary molding die are arranged in two sets in a mirror-symmetrical manner.

[0030] The structural changes of the upper surface of the two sets of primary forming molds from the opposite side to the non-opposite side are as follows: from the opposite side, it first passes through a short horizontal transition, then slopes downward, and finally becomes a horizontal transition section;

[0038] The outlet end of the waste collection slide leads to the waste conveyor belt.

[0039] The beneficial effects of this utility model are:

[0040] This utility model provides an automated processing mold for a rear transverse reinforcing plate. According to the stamping process of the part, a floating material mechanism, a drilling mold, a forming mold, a trimming mold, and a punching mold are sequentially set on the template. All the molds for each process are integrated on the same template, which improves the manual transfer of the material sheet required for a single process to the automatic sequential transfer of the material sheet between the molds of each process, thus saving labor costs.

[0041] In addition to lifting the floating block, the floating mechanism can also float the material. The side of the floating block is set according to the arc edge specifications of the part. The material sheet can be directly trimmed by stamping on the floating block to form the arc-shaped undulating edge of the part.

[0042] An image vision sensor is installed on the feeding side of the template. The image vision sensor can be used to detect whether the material sheet has been completely transferred to the floating block of the floating mechanism. When the material sheet is detected to be in place, the PLC processor can automatically start the machine to realize the first stamping. After the stamping is completed, the floating mechanism floats the material sheet and then transfers it to the next punching mold.

[0043] A reflective photoelectric sensor is installed at the tail end of the trimming and punching die. When the semi-finished part after pressing is completely transferred to the trimming and punching die, and the tail of the semi-finished part just blocks the reflective photoelectric sensor, it means that the semi-finished part has been completely transferred to the trimming and punching die. At this time, the PLC processor controls the machine to start automatically to perform trimming and punching.

[0044] After the floating material block, the punching die, the trimming die, and the punching die press the sheet, waste material will be generated that detaches from the sheet. In order to collect this waste material in a unified manner, a waste material collection slide is set under the floating material mechanism, the punching die, the trimming die, and the punching die. The waste material that detaches from the sheet will fall onto the waste material collection slide and be collected in a unified manner. Attached Figure Description

Detailed Implementation

[0060] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0061] Example 1

[0062] An automated processing mold for a rear transverse reinforcing plate includes: an upper mold base 10, a lower mold base 11, a material floating mechanism 2, a drilling mold 3, a forming mold, a trimming and punching mold 6, and a sensor.

[0063] like Figure 1 As shown, the template consists of two layers, from top to bottom: an upper mold frame 10 and a lower mold frame 11; there is a gap between the upper mold frame 10 and the lower mold frame 11.

[0064] A material lifting mechanism 2 is provided on the upper surface of the upper die holder 10, near the material inlet side, to lift the stamped sheet material. Two sets of the material lifting mechanism 2 are arranged symmetrically in mirror image on the upper die holder 10, allowing simultaneous processing of the left and right rear transverse reinforcing plates. Figure 9 As shown, the floating material mechanism 2 includes: an embedded base 201, a floating material block 202, and a nitrogen telescopic column 203; the lower half of the embedded base 201 is embedded in an embedded groove on the upper surface of the upper mold frame 10; the embedded base 201 and the upper mold frame 10 have telescopic column insertion grooves; the upper opening of the telescopic column insertion groove is opened on the upper surface of the embedded base 201; a nitrogen telescopic column 203 is installed in the telescopic column insertion groove, and a floating material ejector rod 204 is installed at the upper end of the nitrogen telescopic column 203; the upper end of the floating material ejector rod 204 is located at the center of the bottom surface of the floating material block 202; driven by the nitrogen telescopic column 203, the floating material block 202 can be lifted to float the material sheet on the floating material block 202. The nitrogen telescopic column 203 is driven by a control component. The nitrogen telescopic column 203 and the control component are both prior art, and their structures will not be described in detail.

[0065] As a preferred embodiment, such as Figure 3 As shown, the shape of one side of the floating block 202 is formed according to the arc edge shape and direction of the rear transverse reinforcing plate; the aforementioned side is the opposite side of the two sets of mirror-symmetrical floating blocks 202.

[0066] In addition to lifting the floating material on the floating block 202, the material sheet can also be stamped directly on the floating block 202 to form an arc edge shape that matches the arc edge of the floating block 202.

[0067] like Figure 1 As shown, the next step of the floating material mechanism 2 is set as a drilling die 3, which is used to drill holes in the sheet material during stamping; as Figure 4 As shown, two sets of drilling dies 3 are arranged in a mirror symmetrical manner, which can process the left and right rear transverse reinforcing plates at the same time; through holes of the same shape and size as the hole structure on the rear transverse reinforcing plates are opened on the drilling dies 3; after the sheet is stamped on the drilling dies 3, the hole structure is formed on the sheet.

[0068] The next step after drilling mold 3 is to set up a forming mold. The sheet material, after trimming and having holes drilled, is stamped on the forming mold to form the structural shape of the transverse reinforcing plate, resulting in a semi-finished part; for example... Figure 5 As shown, the forming mold includes a primary forming mold 4 and a secondary forming mold 5; the sheet material needs to be stamped on the primary forming mold 4 and the secondary forming mold 5 in sequence to form a semi-finished part; the primary forming mold 4 and the secondary forming mold 5 are arranged in two sets in a mirror symmetrical manner;

[0069] like Figure 10 As shown, the structural changes of the upper surface of the two sets of primary forming molds 4 from the opposite side to the non-opposite side are as follows: from the opposite side, it first goes through a short horizontal transition, then slopes downward, and finally becomes a horizontal transition section; the undulating structure of the upper surface of the primary forming mold 4, the length of the horizontal transition section, the angle and size between the horizontal transition section and the inclined section, etc. are all consistent with the design structure shape and size of the rear transverse reinforcing plate.

[0070] like Figure 12 As shown, the two sets of secondary molding dies 5 are connected by a connecting bridge 501 set above.

[0071] The structural change of the upper surface of the secondary forming mold 5 from the opposite side to the non-opposite side is as follows: it is lowered obliquely downward from the opposite side to the horizontal transition section; the same horizontal transition section and the same inclined section have the same length and angle as the design structure shape and size of the rear transverse reinforcing plate.

[0072] like Figure 1 As shown, a trimming and punching die 6 is set in the next process after the forming die, which is used to trim the burrs or excess parts on the edge of the semi-finished part and to drill holes at the fixed position of the semi-finished part.

[0073] like Figure 6 As shown, the trimming and punching dies 6 are also arranged in two sets in a mirror symmetrical manner, which can process the left and right rear transverse reinforcing plates at the same time; the two sets of trimming and punching dies 6 are embedded in the upper die frame 10; trimming holes and slots are opened on the two sets of trimming and punching dies 6 according to the standard dimensions and edge shapes of the two rear transverse reinforcing plates.

[0074] In this embodiment, the single-process operations of the floating material mechanism 2, the drilling mold 3, the forming mold, the trimming and punching mold 6 for the stamping of the rear transverse reinforcing plate are all integrated into one template. By cooperating with the conveying structure to control the fixed step distance, the material is conveyed on each process mold, thereby completing the whole process. This avoids single-process operation and the need for manual feeding and picking between each process mold, saving labor costs and improving processing efficiency.

[0075] The conveying structure for fixedly conveying raw materials on automotive processing templates is existing technology and has been widely used in automotive automated processing lines. This utility model does not make any technical improvements to the conveying structure, so its structure will not be described in detail.

[0076] Example 2

[0077] Based on Example 1, this example adds a sensor to the template to sense the material feeding and the finishing process, thereby improving the degree of mechanical automation in the operation process.

[0078] like Figure 1 As shown, a first set of sensors 1 is provided on the feeding side of the template. The first set of sensors 1 is used to sense whether the feeding sheet is in place. A second set of sensors 7 is provided at the tail end of the trimming and punching die 6. The second set of sensors 7 is used to determine whether the sheet is properly conveyed to the trimming and punching die 6. The first set of sensors 1 and the second set of sensors 7 are communicatively connected to the PLC processor, and the PLC processor is communicatively connected to the stamping machine control component.

[0079] The first group of sensors 1 mentioned above is configured as an image vision sensor, and the second group of sensors 7 is configured as a reflective photoelectric sensor;

[0080] The image vision sensor can be used to detect whether the material sheet has been completely transferred to the floating block 202 of the floating mechanism 2; when the material sheet is detected to be in place, the PLC processor can send a control command to the machine control component to automatically control the machine to start the first stamping; after the stamping is completed, the floating mechanism 2 floats the material sheet and then transfers it to the next punching mold 3.

[0081] When the sheet material is stamped into shape on the forming mold, a semi-finished part is obtained and conveyed to the next process for trimming and punching. A reflective photoelectric sensor is set at the tail end of the trimming and punching mold 6. When the semi-finished part after pressing is completely conveyed to the trimming and punching mold 6, if the tail of the semi-finished part happens to block the reflective photoelectric sensor, it means that the semi-finished part has been completely conveyed to the trimming and punching mold 6. At this time, the PLC processor sends a control command to the machine control component to control the machine to start automatically and perform trimming and punching.

[0082] Example 3

[0083] Based on Example 1, during the entire processing procedure, the trimming and punching on the floating material block 202, the drilling die 3 for punching holes, and the trimming and punching die 6 will all produce waste material that detaches from the part sheet; this waste material will fall directly onto the lower die holder 11 and accumulate, making it difficult to clean.

[0084] like Figure 2As shown, in this embodiment, waste collection slide plates 8 are provided below the floating material mechanism 2, the drilling mold 3, and the trimming and punching mold 6.

[0085] The inlet end of the waste collection slide plate 8 is located below the upper mold frame 10, within the gap between the upper mold frame 10 and the lower mold frame 11; the inlet end of the waste collection slide plate 8 is directly below the through-hole groove drop channel of the floating material mechanism 2, the drilling mold 3, and the trimming and punching mold 6; the outlet end of the waste collection slide plate 8 leads to the waste conveyor belt.

[0086] After the stamping process described above is completed, the waste material that detaches from the part sheet will fall directly onto its corresponding waste collection slide plate 8, and then travel along the waste collection slide plate 8 to the waste conveyor belt, where it will be collected in a unified manner.
