Description

Technical Field

[0001] The utility model belongs to the technical field of steel plate mold processing, in particular to a steel plate mold trimming device. Background Art

[0002] Steel plates are components needed in many fields, such as construction, machinery, etc., and steel plates are mostly made by mold injection during the production process. The edges of the steel plate parts obtained by injection molding are not smooth enough, so they need to be trimmed by a trimming device.

[0003] The Chinese utility model patent with publication number CN210280811U discloses a trimming device for automobile steel plate molds, including a workbench, a fixed plate is provided on the upper left of the workbench, a first cylinder is provided on the bottom outer wall of the fixed plate near both sides, a guide groove is provided on the top outer wall of the fixed plate, an adjustment component is provided on the fixed plate, the adjustment component includes two support plates parallel to each other, a second motor is fixed to one of the support plates by bolts, a screw rod is connected to the end of the output shaft of the second motor, a fixed block is provided on the screw rod, a guide block is provided at the bottom of the fixed block, and a second cylinder is fixed to the right outer wall of the fixed block by bolts; a trimming component is provided at one end of the second cylinder, and the trimming component includes a connecting plate. The automobile steel plate mold trimming device can adjust the position of the trimming blade to facilitate the trimming work.

[0004] However, the above utility model still has some shortcomings:

[0005] During the use of the above utility model patent, the dust generated during the trimming process is collected through the dust collecting trough. The dust generated during the trimming of the trimming device is extremely light and will be dispersed in the air with the flow of air, and will not fall accurately into the dust collecting trough. This causes some dust to float in the working environment, which not only increases the workload of the staff, but also pollutes the working environment.

[0006] In addition, the steel plate formwork is fixed by suction cups in order to trim the steel plate formwork. When the suction cups are adsorbing and fixing the steel plate formwork, the air between the suction cups and the steel plate formwork needs to be exhausted to ensure the stability of the suction cups' adsorption. Manual adsorption and fixation by suction cups is difficult, and it cannot be guaranteed that the air will be exhausted, resulting in the possibility that the suction cups will detach from the steel plate formwork. Utility Model Content

[0007] The utility model provides a steel plate mold trimming device, aiming to solve the problems mentioned in the above background technology.

[0008] The present utility model is realized as follows. A trimming device for a steel plate mold includes a general base. A bidirectional lead screw is rotatably installed inside the general base. One end of the bidirectional lead screw penetrates the inner wall of the general base and is connected to the output shaft end of a moving motor. On two portions of the side wall of the bidirectional lead screw with opposite threads, nuts are screwed. The side walls of the nuts are connected to mounting plates through connecting bars. An adsorption assembly is installed on the top of one mounting plate, and a reciprocating assembly is installed on the top of the other mounting plate. A trimming assembly is installed on the reciprocating assembly, and a protective assembly is sleeved on the trimming assembly. The protective assembly includes a protective frame with a "C" shape on the front. Through holes are formed at the bottom of the protective frame, and a funnel is fixedly connected to the bottom of the protective frame. The through holes are对接ed to the inlet end of the funnel. A collection box is placed on the top of the general base and directly below the outlet end of the funnel. In this solution, the escape of dust is restricted by the protective frame, and the collection of dust is completed through the funnel and the collection box.

[0009] Preferably, brush rows are fixedly connected to both the inner top and inner bottom of the protective frame. A passage for the steel plate mold to pass through is left between the brush rows. Elastic cloths are bonded to both the front wall and the rear wall of the protective frame. In this solution, the gaps between the protective frame and the steel plate mold are filled by the brush rows and the elastic cloths, further reducing the escape of dust.

[0010] Preferably, the reciprocating assembly includes a fixed plate. The fixed plates are fixedly connected to the top of the left mounting plate in a front-back facing manner. A threaded rod is rotatably installed between the fixed plates. One end of the threaded rod penetrates the fixed plate and is connected to the output shaft end of a reciprocating motor. A threaded block is screwed on the side wall of the threaded rod. The bottom of the side wall of the threaded block is fixedly connected to a connecting plate. The connecting plate is fixedly connected to the side wall of the protective frame. The trimming assembly is installed on the top of the connecting plate. In this solution, the reciprocating motor controls the rotation of the threaded rod, causing the threaded block to drive the connecting plate to move back and forth.

[0011] Preferably, the trimming assembly includes a trimming motor. The trimming motor is installed on the top of the connecting plate. The output shaft end of the trimming motor is connected to a trimming head through a connecting rod. The connecting rod penetrates the side wall of the protective frame. The trimming head is arranged within the space enclosed by the protective frame. In this solution, the trimming motor controls the connecting rod to drive the trimming head to rotate for trimming the steel plate mold.

[0012] Preferably, the adsorption assembly includes a connecting pipe. The connecting pipe is installed on the top of the right mounting plate through a support rod. Both ends of the connecting pipe are connected to suction cups through connecting cylinders. Negative pressure air pumps are installed on the side walls of the connecting cylinders. In this solution, the air between the suction cups and the steel plate mold is exhausted by the negative pressure air pumps to create a vacuum environment, ensuring that the suction cups can firmly adsorb and fix the steel plate mold.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The steel plate mold to be trimmed extends into the protective frame and contacts the trimming head. The side of the steel plate mold is polished through the control cooperation of the reciprocating motor and the trimming motor. The dust generated during the polishing process is confined in the protective frame and guided into the collection box through the funnel, which not only avoids the escape of dust but also realizes the collection of dust.

[0015] When the steel plate mold is placed on the suction cup, the negative pressure vacuum pump is started to exhaust the air in the connecting tube and between the steel plate mold and the suction cup, so that a vacuum is created between the suction cup and the steel plate mold, so that the steel plate mold can be adsorbed and fixed by the suction cup, ensuring the stability of the steel plate mold during the trimming process.

[0031] See also Figure 1-4 The utility model provides a technical solution: a steel plate mold trimming device, including a main base 1, a bidirectional screw rod 2 is rotatably installed in the main base 1, one end of the bidirectional screw rod 2 passes through the inner wall of the main base 1 and is connected to the output shaft end of the mobile motor 5, the mobile motor 5 is installed on the side wall of the main base 1, and the other end is rotatably connected to the inner wall of the main base 1, and the two opposite parts of the thread on the side wall of the bidirectional screw rod 2 are screwed with a nut 3, and the side walls of the nut 3 are connected to a mounting plate 7 through a connecting strip 4, one of the mounting plates 7 is installed with an adsorption component 11 on the top, and the other mounting plate 7 is installed with a reciprocating component 8 on the top, and the reciprocating component 8 is installed with a trimming component 9, and the trimming component 9 is sleeved with a protective component 10;

[0032] The protection component 10 includes a protection frame 101 with a "C" - shaped front. A through - hole 103 is formed at the bottom of the protection frame 101, and a funnel 102 is fixedly connected to the bottom of the protection frame 101. The through - hole 103 is对接 with the inlet end of the funnel 102. A collection box 12 is placed on the top of the total base 1 and directly below the outlet end of the funnel 102.

[0033] Specifically, the upper and lower ends of the connecting bar 4 are respectively fixedly connected to the side wall of the lead screw nut 3 and the bottom of the mounting plate 7. The mounting plate 7 is supported on the top of the total base 1 by moving wheels; Guide grooves 6 are oppositely formed on the top of the total base 1, and the connecting bar 4 is arranged in the guide grooves 6; The moving motor 5 controls the rotation of the bidirectional lead screw 2, so that the two lead screw nuts 3 drive the mounting plate 7 and the corresponding components to move towards each other or move in the opposite direction through the connecting bar 4;

[0034] The steel plate mold to be trimmed is polished inside the protection frame 101. Due to the restriction of the protection frame 101, the dust generated during the polishing process is confined inside the protection frame 101 and enters the collection box 12 under the guidance of the funnel 102;

[0035] The steel plate mold to be trimmed is placed on the top of the adsorption component 11. The steel plate mold is adsorbed and fixed by the adsorption component 11. The moving motor 5 controls the two mounting plates 7 to move towards each other, so that the steel plate mold extends into the protection frame 101 and contacts the trimming component 9. The side of the steel plate mold is polished through the mutual cooperation of the reciprocating component 8 and the trimming component 9. The dust generated during the polishing process is confined inside the protection frame 101 and enters the collection box 12 through the funnel 102, which not only avoids the escape of dust but also realizes the collection of dust;

[0036] Furthermore, brush strips 104 are fixedly connected to both the inner top and inner bottom of the protection frame 101. A channel for the steel plate mold to pass through is left between the brush strips 104. Elastic cloths 105 are bonded to both the front wall and the rear wall of the protection frame 101.

[0037] Specifically, when the steel plate mold extends into the protection frame 101, the brush strips 104 fill the gaps at the top and bottom of the protection frame 101 to prevent the leakage of dust generated during the polishing process. At the same time, when the steel plate mold leaves the protection frame 101, the brush strips 104 can also sweep the dust falling on the steel plate mold; The setting of the elastic cloth 105 shields the front and rear parts of the protection frame 101, reduces the escape of dust, and at the same time gives the steel plate mold a certain space for movement.

[0038] Furthermore, the reciprocating assembly 8 includes a fixed plate 81, which is fixedly connected to the top of the left mounting plate 7 in a front-to-back manner. A threaded rod 82 is rotatably installed between the fixed plates 81. One end of the threaded rod 82 passes through the corresponding fixed plate 81 and is connected to the output shaft end of the reciprocating motor 84.

The connecting plate 85 is supported on the top of the mounting plate 7 through a moving wheel.

[0039] Specifically, the reciprocating motor 84 controls the threaded rod 82 to rotate, so that the threaded block 83 drives the connecting plate 85, the trimming assembly 9 and the protective assembly 10 to move synchronously, so as to trim the steel plate mold under the protection of the protective frame 101.

[0040] Furthermore, the trimming assembly 9 includes a trimming motor 91, which is installed on the top of the connecting plate 85. The output shaft end of the trimming motor 91 is connected to a trimming head 93 through a connecting rod 92. The connecting rod 92 passes through the side wall of the protective frame 101, and the trimming head 93 is arranged in the space enclosed by the protective frame 101.

[0041] Specifically, the two ends of the connecting rod 92 are connected to the output shaft end of the trimming motor 91 and the trimming head 93 respectively; the connecting rod 92 is installed on the side wall of the protection frame 101 through a bearing;

[0042] The trimming motor 91 controls the connecting rod 92 to drive the trimming head 93 to rotate so as to grind the side wall of the steel plate mold.

[0043] Furthermore, the adsorption assembly 11 includes a connecting tube 111, which is installed on the top of the mounting plate 7 on the right side through a support rod. Both ends of the connecting tube 111 are connected to suction cups 113 through connecting tubes 112, and negative pressure vacuum pumps 114 are installed on the side walls of the connecting tubes 112.

[0044] Specifically, the adsorption components 11 are arranged on the top of the right mounting plate 7 in a front-to-back manner, and the two ends of the connecting tube 112 are respectively connected to the suction cup 113 and the connecting tube 111; the bottom of the suction cup 113 is provided with a hole, which is connected to the internal space of the connecting tube 112;

[0045] When the steel plate mold is placed on the suction cup 113, the negative pressure vacuum pump 114 discharges the air in the connecting tube 112 and between the steel plate mold and the suction cup 113 to the outside, so that a vacuum is formed between the suction cup 113 and the steel plate mold, so that the steel plate mold can be adsorbed and fixed by the suction cup 113; the air between the suction cup 113 and the steel plate mold can be completely removed by the negative pressure vacuum pump 114, thereby ensuring the stability of the adsorption of the steel plate mold.

[0046] The working principle and use process of the utility model: After the utility model is installed, the steel plate mold is placed on the suction cup 113, and the negative pressure suction pump 114 is started so that the suction cup 113 can firmly absorb and fix the steel plate mold;

[0047] The moving motor 5 controls the rotation of the bidirectional screw rod 2, and the screw nut 3 drives the mounting plate 7 to move toward each other through the connecting strip 4, so that the steel plate mold extends into the protection frame 101 and is attached to the trimming head 93, and the collecting box 12 is placed below the outlet end of the funnel 102;

[0048] Start the trimming motor 91 and the reciprocating motor 84. The trimming motor 91 controls the connecting rod 92 to drive the trimming head 93 to rotate and grind the side of the steel plate mold. The reciprocating motor 84 controls the threaded rod 82 to rotate, so that the threaded block 83 drives the connecting plate 85, the trimming assembly 9 and the protective assembly 10 to move back and forth, so that the rotating trimming head 93 grinds the side of the steel plate mold back and forth;

[0049] The dust generated during the grinding process falls into the protective frame 101 under the restriction of the protective frame 101 and enters the collection box 12 under the guidance of the funnel 102, thereby completing the collection of the dust.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
