Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing and manufacturing technology, specifically relating to a material floating structure for a rear transverse reinforcing plate. Background Technology

[0002] With economic development, the popularity of automobiles has become increasingly high, and automobiles have become the most important means of transportation for people. However, the requirements for cost control in the development and production of automobile parts are becoming increasingly stringent. We can reduce the number of machine tool strokes and operators by changing the mold from a single-process manual feeding and picking mold to a mechanical automatic feeding machine.

[0003] When the parts are fed into the integrated processing template, after one stamping, the stamped parts need to float to a certain position when the machine is opened again so that they can be transferred to the next process for further processing. However, the current process of floating the parts in the integrated processing template has a low degree of automation. When the machine is opened, manual assistance is required to float the parts. Utility Model Content

[0004] This invention provides a material floating structure for a rear transverse reinforcing plate. This floating structure enables mechanized and automatic material floating when the machine is opened, and can control the position of the floating material to remain consistent each time, ensuring that the material transfer structure can smoothly transfer the material to the subsequent processing steps. This invention solves the problem of needing manual assistance for material floating on integrated templates in automotive parts processing.

[0009] The upper mold frame, the embedded base, and the bottom block are provided with cylindrical slots; the upper opening of the cylindrical slots is provided on the upper surface of the bottom block.

[0010] A nitrogen expansion column is installed inside the cylindrical slot;

[0011] A floating block is provided at the upper end of the nitrogen gas telescopic column; the floating block is located above the bottom block and does not contact the bottom block; under the drive of the nitrogen gas telescopic column, the floating block can move up and down; when the floating block moves up, the material sheet can be floated.

[0012] Preferably, the upper end of the nitrogen telescopic column is connected to the lower end of the floating material top rod; the upper end of the floating material top rod is connected to the lower bottom surface of the floating material block.

[0013] Preferably, the floating block and the floating top rod are connected by a detachable structure;

[0014] A threaded stud is provided in the center of the bottom surface of the floating material block. The stud head is fixed inside the floating material block, and the threaded body of the stud is located outside the floating material block.

[0015] A threaded slot is formed in the center of the upper surface of the float rod;

[0016] By screwing the threaded stud into the threaded slot, the floating block and the floating top rod can be detachably connected.

[0017] Preferably, a limiting protrusion is provided at the upper opening of the cylindrical slot and on the inner wall of the cylindrical slot;

[0018] A limiting retaining ring is provided at the bottom of the floating material top rod and on the side wall of the floating material top rod;

[0019] After the nitrogen gas telescopic column drives the float top rod to rise until the limit stop ring abuts against the limit protrusion, the nitrogen gas telescopic column will no longer be able to raise the float top rod.

[0020] Preferably, a patch pressure sensor is provided on the lower bottom surface of the limiting protrusion;

[0021] The patch pressure sensor is communicatively connected to the PLC processor; the control component of the nitrogen telescopic column is communicatively connected to the PLC processor.

[0022] Preferably, two symmetrical guide rails are formed on the inner wall of the cylindrical slot;

[0023] Two sets of slotted blocks are symmetrically arranged on the outer wall of the limiting ring;

[0024] The two sets of slot embedding blocks are respectively movably embedded in the guide slot rail.

[0025] Preferably, a set of floating material structures is provided on each side of the middle beam of the upper mold frame; the two sets of floating material structures are mirror-symmetrical.

[0026] Preferably, the bottom blocks and the opposite sides of the floating blocks in both sets of the floating material structures are provided with internal opening grooves according to the structure of the processed parts; this utility model is used for the transverse reinforcing plate after processing;

[0027] Preferably, a first end of a negative pressure pipe is provided below the opening on the floating block, and the second end of the negative pressure pipe is connected to a negative pressure air pump.

[0028] The beneficial effects of this utility model are:

[0029] This utility model provides a material floating structure for a rear transverse reinforcing plate, which uses a nitrogen telescopic column to automatically lift the floating material block, thus realizing a mechanical automatic floating operation.

[0030] A float rod is installed at the upper end of the nitrogen expansion column, and a limiting ring is installed on the bottom side wall of the float rod. A limiting protrusion is installed on the inner wall of the upper opening of the cylindrical slot hole for placing the nitrogen expansion column. The nitrogen expansion column drives the float rod to rise, and the float rod drives the float block to rise, thereby floating the material sheet. When the limiting ring abuts against the limiting protrusion, the float rod will stop rising, and the highest point of the float is reached. This ensures that the material sheet is floated to the same position each time.

[0031] A patch pressure sensor is installed on the bottom surface of the limiting protrusion. When the limiting ring abuts against the limiting protrusion, it acts on the patch pressure sensor. At this time, the PLC processor receives the pressure sensing signal and sends a control command to the control component of the nitrogen telescopic column to stop the lifting drive of the nitrogen telescopic column. In this way, when the floating material reaches the highest position, there is no need to manually control the nitrogen telescopic column to stop the lifting drive.

[0032] Symmetrical guide rails are opened on the inner wall of the cylindrical slot, and two sets of slot embedding blocks are symmetrically arranged on the side wall of the limiting retaining ring. The slot embedding blocks are movably set in the guide rails. When the float rod is raised or lowered under the action of the nitrogen gas telescopic column, the cooperation between the slot embedding blocks and the guide rails makes the rise and fall of the float rod and the float block more stable.

[0033] A negative pressure pipe is connected below the opening in the floating block, and the negative pressure pipe is connected to a negative pressure air pump. The material sheet is located on the floating block, and the suction action of the negative pressure air pump can prevent the material sheet from easily shifting on the floating block. When one flush is completed and the floating material reaches the highest point, when it is necessary to transport the material sheet to the next process, the negative pressure air pump stops suction, and at this time the material sheet can be moved relative to the floating block.

[0034] The float rod and the float block are detachably connected by threaded bolts, which facilitates the disassembly and replacement of the float block. Attached Figure Description

Detailed Implementation

[0047] 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.

[0048] Example 1

[0049] A material floating structure for a rear transverse reinforcing plate includes an embedded base 101, a bottom block 102, a floating block 103, and a nitrogen telescopic column 4.

[0050] like Figure 1 As shown, the entire floating material structure 1 is set on the side near the feed end of the processing template. When processing parts, the stamping machine and the transmission structure on the template are existing technologies. They are also set on the existing stamping template. In this utility model, the structure is not improved. Therefore, the transmission structure and the stamping machine structure will not be described in detail. The transmission structure and the connection and installation between the machine and the template are existing technologies mastered by those skilled in the art.

[0051] like Figure 2 As shown, a set of floating material structures 1 is set on each side of the central beam 6 of the template, and the two sets of floating material structures 1 are mirror symmetrical; a piece of material can be floated on each set of floating material structures 1.

[0052] like Figure 3 The figure shows a side cross-sectional view of a set of floating material structures 1. An embedding groove is opened on the upper surface of the upper mold frame 3 of the template. The lower half of the embedding base 101 of the floating material structure 1 is embedded in the embedding groove. The upper half of the embedding base 101 protrudes from the upper surface of the upper mold frame 3. A bottom block 102 is set in the center of the upper surface of the embedding base 101. The upper surface of the bottom block 102 is an arc-shaped surface, and there is a height difference on both sides of the arc-shaped surface.

[0053] A circular slot 301 is formed inside the upper mold frame 3, the embedded base 101, and the bottom block 102. The bottom of the circular slot 301 sinks into the upper mold frame 3, and the upper opening of the circular slot 301 is formed on the upper surface of the bottom block 102. A nitrogen gas telescopic column 4 is set inside the circular slot 301. The lower end of the nitrogen gas telescopic column 4 is located on the lower bottom surface of the circular slot 301. A floating material ejector rod 5 is set at the upper end of the nitrogen gas telescopic column 4. The upper end of the nitrogen gas telescopic column 4 is connected to the lower bottom surface of the floating material ejector rod 5, and the upper end surface of the floating material ejector rod 5 is connected to... The bottom surface of the floating block 103; the floating block 103 is located above the bottom block 102, and there is no connecting structure between the floating block 103 and the bottom block 102; the nitrogen telescopic column 4 extends or retracts under the control of its control component. When the nitrogen telescopic column 4 extends, it controls the floating top rod 5 to rise, and the floating top rod 5 drives the floating block 103 to rise, thereby realizing the mechanical automatic floating of the material pieces on the floating block 103; the above-mentioned nitrogen telescopic column 4 and its control component are existing technologies, and their structure will not be described in detail.

[0054] In a preferred embodiment, when the nitrogen telescopic column 4 drives the floating material operation, the extension or retraction of the nitrogen telescopic column 4 requires manual operation of the control component. However, manual control cannot guarantee that the height position of the floating material remains consistent each time.

[0055] As a preferred embodiment, such as Figure 1 as well as Figure 8 As shown, in this embodiment, a limiting protrusion 7 is provided at the upper opening of the cylindrical slot 301 and on the inner wall of the cylindrical slot 301; while a limiting retaining ring 501 is provided at the bottom of the floating material top rod 5 and on the side wall of the floating material top rod 5; the floating material top rod 5 can just pass between the limiting protrusions 7; when the nitrogen telescopic column 4 drives the floating material top rod 5 to rise, and the floating material top rod 5 drives the floating material block 103 to rise to float the material sheet, when the limiting retaining ring 501 near the bottom of the floating material top rod 5 abuts against the limiting protrusion 7, the floating material top rod 5 will no longer be able to rise, indicating that the floating material has reached the highest position; when the floating material height remains unchanged, the material sheet is conveyed to the next process; at the same time, the operator controls the nitrogen telescopic column 4 to retract; with the cooperation of the limiting retaining ring 501 and the limiting protrusion 7, it can be ensured that the floating material position is consistent each time, which helps the conveying structure to accurately capture the material sheet and bring it into the next process.

[0056] Example 2

[0057] Based on Embodiment 1, the limiting ring 501 and the limiting protrusion 7 are set in Embodiment 1 to achieve the purpose of controlling the position of the floating material to be consistent each time; however, when the floating material reaches the highest position and remains unchanged, it is necessary to manually control the control component of the nitrogen telescopic column 4 to make the nitrogen telescopic column 4 retract to its original position.

[0058] like Figure 7 As shown, this embodiment optimizes the above-mentioned workflow. A patch pressure sensor 10 is installed on the lower surface of the limiting protrusion 7. The patch pressure sensor 10 is communicatively connected to the PLC processor, and the control component of the nitrogen telescopic column 4 is also communicatively connected to the PLC processor. When the nitrogen telescopic column 4 drives the floating material top rod 5 to rise until the limiting ring 501 abuts against the limiting protrusion 7, the limiting ring 501 exerts pressure on the patch pressure sensor 10. After receiving the pressure signal, the PLC processor sends a control command to the control component of the nitrogen telescopic column 4, and the control component drives the nitrogen telescopic column 4 to retract to its original position. This embodiment introduces the patch pressure sensor 10 to monitor the pressure signal when the limiting ring 501 contacts the limiting protrusion 7, thereby automatically determining that the floating material has reached its highest position, and the PLC processor automatically controls the retraction of the nitrogen telescopic column 4. There is no need to manually check that the floating material height remains unchanged before manually controlling the retraction of the nitrogen telescopic column 4.

[0059] Example 3

[0060] Based on Example 1, in order to make the nitrogen gas telescopic column 4 drive the float rod 5 to rise more smoothly, and the float rod 5 drives the float block 103 to rise more smoothly, such as... Figure 8As shown, in this embodiment, two symmetrical guide rails 11 are opened on the inner wall of the cylindrical slot 301. Two sets of slot embedding blocks 1101 are symmetrically arranged on the outer wall of the limiting retaining ring 501 at the bottom of the float rod 5. The two sets of slot embedding blocks 1101 are respectively movably embedded in the two symmetrical guide rails 11. When the float rod 5 drives the float block 103 to rise, due to the cooperation between the guide rails 11 and the slot embedding blocks 1101, the rising and falling process of the float rod 5 and the float block 103 is more stable.

[0061] Example 4

[0062] Based on Example 1, the sheet is located on the floating block 103. After one stamping is completed, the sheet needs to be floated up and transported to the next process by the conveying structure. In order for the conveying structure to accurately capture the floating sheet, the sheet needs to be kept in a fixed position. If the sheet is displaced, it may cause the conveying structure to capture the sheet off-center.

[0063] like Figure 6 As shown, several openings 1031 are formed inside the floating block 103, penetrating the upper and lower surfaces of the floating block 103. Two of the openings 1031 are selected, and a negative pressure pipe 9 is installed below the openings 1031. The first end of the negative pressure pipe 9 is connected to the opening below the opening 1031, and the second end of the negative pressure pipe 9 is connected to a negative pressure air pump. When the material sheet is on the floating block 103, the suction action of the negative pressure air pump keeps the material sheet tightly attached to the floating block 103. This ensures that the material sheet will not shift. When the material sheet reaches its floating position and is ready to be conveyed to the next process, the negative pressure suction action is eliminated, and the material sheet can move normally from the floating block 103. Before conveying, the material sheet is kept from shifting, ensuring that the conveying structure can accurately capture the material sheet.

[0064] Example 5

[0065] Based on Embodiment 1, in Embodiment 1, the floating block 103 is directly connected to the floating top rod 5; when the structural shape of the floating block 103 does not meet the structural shape of the processed part sheet, it may be necessary to replace the floating block 103.

[0066] like Figure 9 As shown, in this embodiment, the connection between the floating block 103 and the floating top rod 5 is set to be detachable and replaceable; a threaded stud 1032 is set in the center of the bottom surface of the floating block 103, the stud head of the threaded stud 1032 is fixedly set inside the floating block 103, and the threaded stud body of the threaded stud 1032 is located outside the floating block 103.

[0067] A threaded slot is centrally located on the upper surface of the float rod 5; by screwing the threaded bolt 1032 into the threaded slot, the float block 103 and the float rod 5 can be detachably connected. Whether the float block 103 needs to be installed or removed, the threaded bolt 1032 can be screwed together with the float block 103.
