Description

Technical Field

[0001] The utility model belongs to the technical field of machining auxiliary tools, and in particular relates to a mobile limiting device. Background Art

[0002] At present, steel plate embossing machines generally use a pair of steel rollers with "yin and yang" patterns on the surface. The squeezing between the steel rollers causes the soft steel plate to deform and form patterns. However, during the embossing process, the steel rollers must maintain strict phase synchronization and alignment to ensure the embossing quality. Although phase-synchronized gears are designed to achieve this technical requirement, inaccurate gear meshing or slippage between the steel rollers will still cause phase differences and lead to quality problems in embossing.

[0003] In the prior art, the patent document with the announcement number CN 104589882 B discloses a phase fine-tuning device for an embossing roller of a steel plate embossing machine, wherein the fixing pin is threadedly connected to the non-transmission embossing roller phase synchronization gear, the fine-tuning flange is fixedly connected to the end face of the non-transmission embossing roller phase synchronization gear by the third bolt, the first bolt is installed in the threaded hole on the fine-tuning flange, the outer ring of the sliding bearing is connected to the non-transmission embossing roller phase synchronization gear by interference fit, and the inner ring of the sliding bearing is connected to the embossing roller shaft head by clearance fit. The above scheme eliminates the phase difference of the pattern by adjusting before processing, and the embossing roller undertakes the feeding and embossing work at the same time, but the embossing roller is prone to wear and slippage, so its processing efficiency and quality are poor. If a modified press is used for one-time pressing and forming, there is almost no phase difference affecting the embossing quality, but when the steel plate is embossed, the stability of the steel plate placement position will affect the embossing quality, and the steel plate can only be fed manually, which seriously affects the embossing work efficiency and has certain safety hazards. Utility Model Content

[0029] Example:

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown: a movable limiting device includes a pressing base 1, a pressing top seat 2 and a lifting mechanism 3, the lifting mechanism 3 is installed between the pressing base 1 and the pressing top seat 2, the pressing base 1 and the pressing top seat 2 are arranged opposite to each other, and the lifting mechanism 3 drives the pressing top seat 2 to move up and down relative to the pressing base 1, a working boss 4, i.e., a processing platform is arranged on the pressing base 1, an upper die structure 5 is installed on the upper surface of the working boss 4, a lower die structure 6 is installed on the lower surface of the pressing top seat 2, the upper die structure 5 and the lower die structure 6 are arranged opposite to each other, and a movable limiting device 7 is arranged on the side of the working boss 4.

[0031] The above-mentioned movable limiting device 7 includes a first supporting foot seat structure 71 and a first limiting slide rail platform 72. The first limiting slide rail platform 72 is arranged on the top of the first supporting foot seat structure 71. The first limiting slide rail platform 72 is arranged on the side of the working boss 4, and the upper surface of the first limiting slide rail platform 72 is flush with the upper die structure 5. A limiting clamping seat 73 is slidably installed on the first limiting slide rail platform 72. A driving mechanism 74 is also installed on the top of the first supporting foot seat structure 71. The output end of the driving mechanism 74 is connected to a screw structure 75. The driving mechanism 74 is composed of a motor and a reduction transmission mechanism. The motor, the reduction transmission mechanism and one end of the screw structure 75 are sequentially connected in transmission. The screw structure 75 is arranged in parallel with the first limiting slide rail platform 72. A screw hole structure is provided in the limiting clamping seat 73, and the screw structure 75 cooperates with the screw hole structure.

[0032] The above-mentioned movable limiting device 7 also includes a second supporting foot seat structure 76 and a second limiting slide rail platform 77. The second limiting slide rail platform 77 is arranged on the top of the second supporting foot seat structure 76. The second limiting slide rail platform 77 is arranged on the other side of the working boss 4. A driven limiting clamping seat 78 is slidably installed on the second limiting slide rail platform 77. The driven limiting clamping seat 78 can also be driven by a driving mechanism like the above-mentioned limiting clamping seat, but it needs to be regulated by a control unit. Therefore, a sliding rod 79 is also arranged on the top of the first supporting foot seat structure 71. The sliding rod 79 is arranged parallel to the second limiting slide rail platform 77. A sliding hole structure is provided in the driven limiting clamping seat 78. The sliding rod 79 cooperates with the sliding hole structure, and a spring structure 710 is sleeved on the sliding rod 79. The two ends of the spring structure 710 are respectively connected to the driven limiting clamping seat 78 and the second supporting foot. The seat structure 76 is connected at the top, and a linkage lever structure 711 is connected to the limit seat 73. The linkage lever structure 711 can be in contact with the driven limit seat 78 by being pushed, or it can be fixedly connected, but it is generally not applicable. The linkage lever structure 711 can also be omitted, and the driven limit seat 78 can be clamped on the side of the steel plate by the elastic force of the spring structure 710. However, the shell steel plate of the lamp is generally thinner, and the elastic force acting on the side of the thinner steel plate is too large, which makes the steel plate arched and inconvenient to process, or it can bounce out of the driven limit seat 78 and injure people. Therefore, the linkage lever structure 711 is used to move the driven limit seat 78 and compress the spring structure 710. The first support foot structure 71 and the second support foot structure 76 are both provided with a threaded lifting structure for adjusting the height of the slide rail platform to suit different molds and steel plate thicknesses.

[0033] Among them, the limit clamp 73 and the driven limit clamp 78 are both in the shape of an "I" character, the first limit slide rail platform 72 and the second limit slide rail platform 77 are both composed of two parallel slide rails, and the two sides of the limit clamp 73 and the driven limit clamp 78 are respectively clamped on the two parallel slide rails of the first limit slide rail platform 72 and the second limit slide rail platform 77.

[0034] The screw rod structure 75 and the sliding rod 79 are respectively arranged between the two parallel slide rails of the first limiting slide rail platform 72 and the second limiting slide rail platform 77. The first support foot seat structure 71 and the second support foot seat structure 76 are both composed of a support foot seat. One end of the two parallel slide rails of the first limiting slide rail platform 72 and the second limiting slide rail platform 77 are connected to the support foot seat, and the other end is placed on the side of the working boss 4, and a connecting plate is arranged between the other ends of the two parallel slide rails. The screw rod structure 75 and the sliding rod 79 are rotatably installed in the middle of the connecting plate.

[0035] The lifting mechanism 3 includes a lifting support column structure 31 and a lifting drive cylinder structure 32. The lifting drive cylinder structure 32 is installed in the pressing top seat 2. One end of the lifting support column structure 31 is slidably installed in the lifting drive cylinder structure 32. The other end of the lifting support column structure 31 is installed on the pressing base 1. The lifting support column structure 31 is composed of four lifting support columns. The four lifting support column structures 31 are respectively arranged at the four corners of the pressing base 1 and the pressing top seat 2. The lifting drive cylinder structure 32 is composed of four lifting drive cylinders. The upper and lower cylinder cavities of the four lifting drive cylinders are respectively connected.

[0036] A mounting slot platform 11 is also provided on the pressing base 1. The mounting slot platform 11 is provided on both sides of the working boss 4, and an inverted T-shaped slot 12 is evenly opened on the upper surface of the mounting slot platform 11; similarly, a bearing press platform 21 is provided at the bottom of the pressing top seat 2, and T-shaped slots 22 are evenly opened on the lower surface of the bearing press platform 21.

[0037] The upper die structure 5 comprises an upper support plate 51 and an upper die plate 52. The upper die plate 52 is fixedly arranged in the middle of the upper support plate 51, and the pattern surface of the upper die plate 52 is arranged upward. One or two mounting plates 53 are installed on both sides of the upper support plate 51 through a bolt structure. An inverted T-shaped clamp 54 is provided at the bottom of the mounting plate 53. The inverted T-shaped clamp 54 is installed in the inverted T-shaped slot 12 and is tightened and fixed in position by bolts. Figure 5 As shown, the inverted T-shaped clamping head 54 is tightened with bolts, so that a great positive pressure is generated between the inverted T-shaped clamping head 54 and the inner wall of the inverted T-shaped clamping groove 12, thereby preventing it from moving.

[0038] The above-mentioned lower die structure 6 includes a lower support plate 61 and a lower die plate 62. The lower die plate 62 is fixedly arranged in the middle of the lower support plate 61, and the pattern surface of the lower die plate 62 is arranged downward. One or two mounting pressure plates 63 are installed on both sides of the lower support plate 61 through a bolt structure. The outer end of the mounting pressure plate 63 is provided with a T-shaped clamp 64, which is installed in the T-shaped clamp groove 22 and fixed in position by a nut. The mounting pressure plate 63 is staggered with the mounting pull plate 53 to avoid interference. The above structure is convenient for stably installing the upper die structure 5 and the lower die structure 6 with different patterns. It not only has a wide range of applications, but also only requires easy adjustment and alignment.

[0039] Its working principle is as follows: the pressing top seat 2 is controlled to move up and down by the lifting mechanism 3, so that the lower die structure 6 and the upper die structure 5 can complete the embossing work on the lamp housing steel plate at one time, and the embossing efficiency is high. Because the upper die plate 52 and the lower die plate 61 will not produce sliding friction with the steel plate, there will be no pattern alignment error during the embossing process, and the embossing mold will wear less, and even if wear occurs, it will not affect the embossing quality; a movable limit device 7 is provided, which can stably place and limit the side of the steel plate to be processed through a limit clamping seat 73 to ensure that the steel plate will not move during embossing, so that the embossing quality is more stable, and it can adapt to embossing steel plates of different lengths, and after the local embossing of the steel plate is completed, the steel plate is moved to emboss other parts; a driven limit clamping seat 78 is provided to clamp the side of the steel plate that has completed the embossing work, so that the steel plate as a whole is more stable, which is convenient for subsequent processing and safe and stable material unloading, avoiding safety hazards caused by manual operation.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention shall be defined by the appended claims.
