Description

TECHNICAL FIELD

[0001] The present application relates to the field of metal stamping, in particular to a die structure for processing an automobile lamp shell. BACKGROUND

[0002] The lamp shell is a device for installing the lamp cover and the internal lamp body. The lamp shell, like the automobile shell, needs to be stamped from a metal sheet. Stamping is a cold deformation process for metal. With the power of a special stamping device, the metal sheet is directly subjected to deformation force in the die and deformed to obtain a product part with a certain shape, size and performance. The specific work flow is to place the metal sheet on the unified die according to the pre-set program, and to determine that the metal sheet and the die are completely fixed. Then, according to the pre-set program, the stamping part is operated to stamp and punch the metal sheet, thereby obtaining the required metal lamp shell.

[0003] The existing Chinese patent with publication number CN112517754B discloses an automatic precision stamping die, which comprises a base mechanism, a material pouring mechanism, a die mechanism, a stabilizing mechanism and a driving mechanism. The base mechanism comprises a stamping base, a connecting sleeve, a first screw groove, a first support column and a second support column. The top corners of the stamping base are fixed with connecting sleeves. The beneficial effects of the present application are as follows: through the work of two electric telescopic rods, the telescopic end of the electric telescopic rod extends, the movable type inverted rod is moved away from the end of the side plate through the pin shaft seat and the movable pin shaft, and the movable type inverted rod is rotated around the first movable shaft as the axis point. In order to achieve better overturning effect, the V-shaped inverted rod is inserted into the slot inside the slot on the two U-shaped clamping seats, so as to increase the inclination angle of the material pouring plate. The inclination of the material pouring plate drives the concave die to incline, so that the debris generated in the concave die is poured out, avoiding the problem of affecting the subsequent processing caused by the debris remaining in the concave die.

[0004] However, the automatic precision stamping die still has the following defects:

[0005] 1. The automatic precision stamping die has insufficient automation effect. The metal raw material needs to go through multiple steps when being stamped in the die. The lamp shell workpiece has a complex shape. The stamping can be divided into the following stages: blanking stage, stamping stage, shaping stage, flanging stage and lateral punching stage. Therefore, the angle between the metal sheet and the stamping part needs to be adjusted constantly during processing. The metal sheet needs to be moved back and forth on the operation table to be stamped by different stamping parts, so as to achieve the effect of automatic stamping.

[0006] 2. The automatic precision stamping die falls waste, cannot adjust back the angle of the die in time, and the pressure applied to the metal plate and the die during stamping is huge, the main part inside the electric telescopic rod is the telescopic part, which is easy to damage after stamping, in addition, the force applied in the opposite direction of the electric telescopic rod will affect the stamping effect of the metal plate, in addition, the die of the device has no strengthening and fixing effect, after the stamping part repeatedly applies force to the device from different directions, the die and the plate in the die will be misaligned, thereby affecting the accuracy of the car lamp shell.

[0026] The present invention provides a mold structure for processing automobile lamp housings through improvements. Compared with the prior art, it has the following improvements and advantages:

[0027] The headlight shell processing mechanism includes a headlight shell deburring processing component and a headlight shell moving processing component. The cooperation of the internal guide pillars and the rotating bracket of the headlight shell deburring processing component and the headlight shell moving processing component facilitates multiple stamping at different angles. The cooperation of the auxiliary working component, the headlight shell processing mechanism and the headlight shell mold component can improve the automation effect of automobile headlight shell processing. Through the pre-set program, it is convenient to perform stamping and shaping, burr repair and shaping, and side punching after flanging on the headlight shell workpiece in sequence. During processing, the above structures cooperate with each other to continuously adjust the angle between the metal sheet and the stamping part according to the required stamping and punching effect.

[0028] Firstly, the vehicle lamp shell mold assembly can enhance the fixing effect of the mold set, because the angle of the metal plate on the mold set needs to be adjusted constantly during the automatic stamping process, in addition to the normal downward stamping and shaping, the metal plate also needs to be side-punched, which will cause errors between the relative positions of the metal plate and the preset relative positions, thereby increasing the number of defective products. In addition, the bottom of the supporting bottom plate is hollow to facilitate the falling of waste after punching, and the auxiliary working assembly can also assist in the falling of waste when moving the vehicle lamp shell mold assembly, because the inner groove is embedded in the middle position of the working plane. The vehicle lamp shell mold assembly and the auxiliary working assembly can drive the metal plate fixed at the top of the vehicle lamp shell mold assembly to move linearly on the working plane.

[0029] Secondly, the vehicle lamp shell processing mechanism can adjust the distance and angle between the stamping part and the metal plate on the mold set in all directions, and remove the internal burrs of the punched hole, thereby achieving the effect of automatic stamping mold. In addition, the guide pillar can improve the accuracy of stamping when pushing the mold stamping plate. The vehicle lamp shell processing mechanism specifically achieves the above effects through the cooperation of the vehicle lamp shell moving processing assembly and the vehicle lamp shell deburring processing assembly.

[0030] The specific process is that the auxiliary working assembly and the vehicle lamp shell mold assembly cooperate to send the metal plate to the bottom end of the vehicle lamp shell moving processing assembly, align and insert the positioning insert and the positioning slot, so that the vehicle lamp shell moving processing assembly can stamp the metal plate on the mold set, and then the metal plate after the first punching is moved to the bottom end of the vehicle lamp shell deburring processing assembly by the auxiliary working assembly. The vehicle lamp shell deburring processing assembly can rotate to adjust the angle of the stamping part, so as to deburr and polish the punched hole on the metal plate. The rotating table can control the stamping head to move along the inner wall of the punched hole, thereby achieving the effect of grinding burrs. After the metal plate is vertically punched for the first time, the edge bending can begin to be side-punched. At this time, the vehicle lamp shell mold lower die plate is turned over, the insert is inserted into the positioning slot and the side positioning hole, so that the vehicle lamp shell mold lower die plate can be erected to facilitate side punching of the metal plate. Finally, the processed automobile lamp shell forming body is obtained. BRIEF DESCRIPTION OF DRAWINGS

[0043] The following will be combined with the Figures 1 to 10 The present invention is described in detail, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0044] The present invention provides a mold structure for processing automobile lamp housing by improving the structure. Figure 1-10 As shown in the figure, the mold structure for processing automobile lamp housings includes a metal angle iron frame 2, a lamp housing processing mechanism 6 is installed on the top of the metal angle iron frame 2, and the lamp housing processing mechanism 6 performs stamping and deburring on the metal sheet in the lamp housing mold, and an auxiliary working component 1 is installed on one side of the metal angle iron frame 2, through which the metal sheet on the mold group can be pushed to move back and forth on the operating table, and the top of the auxiliary working component 1 is installed with a lamp housing mold assembly 4, which can enhance the fixing effect of the mold group. Because the angle of the metal sheet on the mold group needs to be continuously adjusted during the automated stamping process, in addition to the normal downward stamping and shaping, flanging and side punching are also required, which will cause the relative position between the metal sheet and the stamping part to have an error with the preset relative position, thereby leading to an increase in defective products. The auxiliary working component 1 can reciprocate the lamp housing mold assembly 4, and the lamp housing mold assembly 4 fixes the lamp housing mold and the metal sheet;

[0045] The auxiliary working assembly 1 includes a first motor 110, which is started by an external power supply. A limit screw 108 is installed at the output end of the first motor 110, which drives the limit screw 108 to rotate. The limit screw 108 drives the lamp housing mold assembly 4 to move by moving the second movable slider 109.

[0046] The auxiliary working assembly 1 also includes a working plane 101, which is placed on one side of the metal angle iron frame 2. An embedded groove 103 is embedded in the middle of the working plane 101.

Because the headlight housing mold assembly 4 itself is a set of movable structures, it needs to move back and forth on the workbench and needs to withstand the pressure applied by the stamping parts. Each stamping will cause wear to the parts in the headlight housing mold assembly 4, so it is easy to damage the metal sheet when moving it;

[0048] The headlight housing mold assembly 4 includes a clamping screw 404, and the clamping screw 404 is installed on the top of the auxiliary working assembly 1;

The output end of the clamping screw 404 is connected to a clamp. The side plate 405 is held, and the clamping screw 404 at the bottom is started, and the clamping side plate 405 is retracted and tightened to clamp and fix the lower template 407 of the lamp housing mold, so as to increase the stability of the metal sheet and the lower template 407 of the lamp housing mold. The clamping side plate 405 is set to be trapezoidal and the grooves on both sides of the interior are further convenient for dropping waste.

[0063] In addition, the cooperation of the auxiliary working component 1, the headlight shell processing mechanism 6 and the headlight shell mold component 4 can improve the automation effect of automobile headlight shell processing. Through the pre-set program, it is convenient to perform stamping and shaping, burr repair and shaping, and side punching processing after flanging on the headlight shell workpiece in sequence; during processing, the above structures cooperate with each other to continuously adjust the angle between the metal sheet and the stamping part according to the required stamping and punching effect.

[0064] Working principle: First, the auxiliary working component 1 and the headlight housing mold component 4 cooperate to send the metal sheet to the bottom end of the headlight housing mobile processing component 5, align the positioning plug-in 511 and the positioning slot 408, and insert it to facilitate the headlight housing mobile processing component 5 to punch the metal sheet on the mold group, and then the first punching can be performed. Then, the auxiliary working component 1 moves the metal sheet after the first punching to the bottom end of the headlight housing deburring processing component 3. The headlight housing deburring processing component 3 can rotate to adjust the angle of the stamping part, which is convenient for metal deburring. The holes punched on the sheet are deburred and ground. The rotary table can control the punch head to move along the inner periphery of the punched hole, thereby achieving the effect of grinding the burrs. Then, after the metal sheet undergoes the first vertical punching process, the edge is bent and the flanging and lateral punching process can begin. At this time, the lower template 407 of the headlight housing mold is flipped over, and the positioning slot 408 and the side positioning hole 410 are inserted through the plug-in. The lower template 407 of the headlight housing mold can be erected to facilitate the lateral punching process on the metal sheet, and finally the processed automobile headlight housing molded body 409 is obtained;

[0065] Further, the more specific working principle process is as follows:

[0066] First, the metal sheet is placed on the top of the lower template 407 of the lamp housing mold through the lamp housing mold assembly 4, so that the metal sheet is completely embedded in the lower template 407 of the lamp housing mold. Then, the clamping screw 404 at the bottom is started, and the clamping side plate 405 is retracted and tightened to clamp and fix the lower template 407 of the lamp housing mold, so as to increase the stability of the metal sheet and the lower template 407 of the lamp housing mold. The narrow size of the supporting bottom plate 403 is convenient for dropping waste, and the clamping side plate 40 5 is set in a trapezoidal shape and has through grooves on both sides to further facilitate the falling of waste materials. In addition, a reinforced buffer pad is provided at the bottom of the clamping side plate 405 to further strengthen the effect of fixing the lower template 407 of the lamp housing mold. In addition, the positioning slots 408 on both sides of the lower template 407 of the lamp housing mold are used to facilitate the positioning of the lamp housing moving processing assembly 5 during stamping. The side positioning socket 410 at the top of the clamping side plate 405 is used to fix the lower template 407 of the lamp housing mold during the next step of side punching after flanging.

[0067] Then, the auxiliary working component 1 can push the metal sheet on the mold group to move back and forth on the operating table. Specifically, the first motor 110 is started by an external power supply to drive the limiting screw 108 to rotate. The limiting screw 108 drives the second movable slider 109 to move linearly inside the supporting slide rail 107 through thread transmission. The top of the second movable slider 109 is installed through the movable support plate 105 and the headlight housing mold assembly 4, which is convenient for dragging the headlight housing mold assembly 4 to move. The first motor 110 is installed at the bottom end of the working plane 101. The middle position of the working plane 101 is inlaid with an embedded groove 103, and the movable support plate 105 slides inside the embedded groove 103. In addition, the two ends of the bottom of the clamping screw rod 404 are respectively connected to the two groups of first movable sliders 104, and the first movable slider 104 slides on the first limiting slide rail 102, which is convenient for stabilizing the chassis of the headlight housing mold assembly 4, and the multiple groups of limiting and sliding structures inside the auxiliary working component 1 cooperate to improve the stability of the movement of the headlight housing mold assembly 4. Because the headlight housing mold assembly 4 itself is a group of movable structures, it needs to move back and forth on the workbench, and it needs to withstand the pressure applied by the stamping parts. Each stamping will cause wear on the parts in the headlight housing mold assembly 4, so it is easy to be damaged, resulting in damage to the metal sheet when the metal sheet is moved.

[0068] Finally, the working principle of the headlight housing moving processing assembly 5 is to start the telescopic motor 502 to drive the first support back plate 504 to move along the direction of the first guide pillar 503 through telescopic movement, so as to adjust the horizontal position of the upper pressure plate 510 of the mold relative to the metal sheet, and then start the second guide pillar 505 to further extend the distance that the upper pressure plate 510 of the mold moves on the horizontal line to adapt to longer metal sheets and increase the inclusiveness of the device. In addition, the upper pressure plate 510 of the mold is pushed down by the third guide pillar 507 to stamp the mold and the metal sheet to make the headlight housing. It should be noted that the positioning plug-in 511 and the positioning slot 408 need to be aligned and inserted at this time to facilitate positioning and avoid the hidden dangers of uneven force and deviation. In addition, the third support back plate 508 is installed on the slide on the side of the third guide pillar 507 through the second mounting block 509, and the front and side of the slide are provided with second mounting blocks 509 to facilitate adjustment of the position of the upper pressure plate 510 of the mold.

[0069] The working principle of the deburring processing assembly 3 of the car lamp shell is that firstly, the first slide rail 304 is started, and the deburring polishing head 310 at one end is pushed to move to the direction of the one side metal plate material through the cooperation of the first slide rail 304 and the first screw rod 305, then the first moving slide table 307 is started to move the deburring polishing head 310 at one side of the second triangular supporting frame 309 to the direction of the bottom end metal plate material, until the deburring polishing head 310 is placed at the burr around the hole of the metal plate material, at this time, the position of the metal plate material can be adjusted through the auxiliary working assembly 1, so as to adjust the relative position between the deburring polishing head 310 and the hole, then the second motor 302 is started through the external power supply, the second motor 302 drives the rotating supporting plate 303 to rotate, the rotating supporting plate 303 drives the deburring polishing head 310 to move along the inner wall of the hole of the metal plate material, and the burr around the hole due to the stamping of the moving processing assembly 5 of the car lamp shell is polished.
