Description

Technical Field

[0001] The utility model relates to the field of stamping, in particular to a deviation correcting device for stamping equipment. Background Art

[0002] Stamping usually uses a die to process materials into required parts in batches, and then transports the parts to be stamped to the stamping die for stamping through a feeding device such as a conveyor belt. After feeding, a correction device is needed to align the parts to be stamped to ensure the stamping effect. A stamping die feeding correction device is disclosed in the Chinese utility model patent with announcement number CN220295711U. It mainly measures the distance of the die to be stamped by an infrared rangefinder, and the measurement results are transmitted to the control console. After analysis by the control console, the servo motor drives the slider to slide through the screw rod, and then the push rod and the push block can be pushed to push the sheet to be stamped to the correct position. This method can correct the deviation of the parts to be stamped according to their actual conditions.

[0003] Regarding the above-mentioned related technologies, the inventor believes that the following defects exist: multiple springs and guide pillars are arranged inside the push block, and the position of the spring on the push block contacts the workpiece and pushes the workpiece to the correct position. After the springs on the multiple push blocks on the front and rear sides frequently contact the workpiece, the positions may be different each time, which also causes the force pushed by each push block and spring to be different, and the strain caused by these springs is also different. The unequal strength of the springs on both sides may cause the workpiece to deviate downward to the side with less force. For this reason, we designed a correction device for stamping equipment. Utility Model Content

[0004] In order to solve the technical problem that one side is offset when correcting the front and rear sides, the utility model provides a correction device for a stamping equipment.

[0005] The utility model is implemented by the following technical scheme: a correction device for a stamping equipment, comprising two groups of fixed plates arranged on the left and right sides of a stamping equipment machine, a movable screw is rotatably installed between each group of two fixed plates, two movable screw seats are symmetrical on the left and right and movably installed on the left and right ends of the movable screw, and mounting frames are arranged inwardly above the movable screw seats, and correction rollers are rotatably installed at the front and rear ends of the mounting frames through mounting shaft pins, and a lower pressure roller and a support roller are slidably installed in sequence from top to bottom between the two correction rollers.

[0006] As a further improvement of the above scheme, a guide rod is horizontally arranged below the two fixed plates on the same side, and the lower end of the movable screw seat is slidably sleeved on the guide rod. The setting of the guide rod can limit the movable screw seat, so that it can move back and forth left and right as needed.

[0007] As a further improvement of the above scheme, the movable screw is composed of two screws welded together, and the spiral lines on the two screws rotate in opposite directions. When the movable screw rotates, the two movable screw seats on the left and right sides can move inward or outward at the same time, thereby making the deviation correction roller move synchronously, so as to facilitate the plate to be placed in the middle position of the mold on the machine table of the stamping equipment;

[0008] The right end of the movable screw rod extends outward to form an extended handle, which is convenient for rotating the movable screw rod.

[0009] As a further improvement of the above scheme, the support roller is rotatably arranged on the lower bracket through an axle pin, and the upper surface of the outer ring of the support roller is flush with the upper surface of the mold on the punching equipment machine, thereby being able to support the left and right ends of the plate on the mold and prevent the lower pressure roller from bending downward due to excessive downward pressure;

[0010] Adjustment slide holes are formed through the left and right ends of the outward-facing surface of the mounting frame, and a fixing screw is integrally provided at the outward-facing end of the lower bracket. The fixing screw passes through the adjustment slide hole and is placed outside the mounting frame, and a fixing nut is threadedly connected to the fixing screw. A flat plate is placed on the upper surface of the mold, and then the support roller is moved upward, and the outer ring surface of the support roller is moved to contact the lower surface of the flat plate. At this time, the fixing nut can be tightly screwed on the fixing screw.

[0011] As a further improvement of the above scheme, a threaded hole is installed on the top of the mounting frame, the adjusting screw is threadedly connected in the threaded hole, and the lower end of the adjusting screw is rotatably connected to the upper bracket, the lower pressure roller is rotatably installed on the upper bracket through an axle pin, the inner surface of the upper bracket is in sliding contact with the inner surface of the mounting frame, and the height of the lower pressure roller can be changed as needed under the action of the adjusting screw, so that it can be pressed on the upper surface of the plate, which can prevent it from warping and is suitable for plates of various thicknesses.

[0012] As a further improvement of the above scheme, a circular hole is formed downwardly through the upper surface of the mounting frame, and the circular hole extends downward to the bottom of the mounting frame. The mounting shaft pin is vertically arranged on the mounting frame through the circular hole, and the deviation correction roller is rotatably sleeved on the mounting shaft pin. The mounting shaft pin includes a straight rod and a disc. The straight rod is fixed under the disc, and the disc is fixed to the top of the mounting frame by screws. This facilitates the installation and disassembly of the mounting shaft pin, and further facilitates the installation and disassembly of the deviation correction roller.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model arranges symmetrical deviation-correcting rollers on the left and right sides of the stamping die. The multiple deviation-correcting rollers can ensure that the stamping sheet moves along the specified direction without positional deviation. The deviation-correcting rollers will not be offset due to long-term use, thereby improving accuracy.

[0015] 2. By arranging support rollers on the mounting frame, the support rollers can support the stamping sheet together with the mold, and can ensure that the extrusion of the lower pressure roller will not cause bending at both ends of the thinner sheet. In combination with the lower pressure roller, the two sides of the sheet will not warp up, which is convenient for subsequent stamping. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0024] Example:

[0025] Please combine Figure 1-Figure 5A correction device for a stamping equipment in this embodiment includes two groups of fixed plates 1 arranged on the left and right sides of the stamping equipment machine, a moving screw 3 is rotatably installed between each group of two fixed plates 1, two moving screw seats 5 are symmetrical and movably installed on the left and right ends of the moving screw 3, and mounting frames 2 are arranged inward above the moving screw seats 5, and correction rollers 6 are rotatably installed at the front and rear ends of the mounting frames 2 through mounting shaft pins 61, and a lower pressure roller 8 and a support roller 7 are slidably installed in sequence from top to bottom between the two correction rollers 6.

[0026] A guide rod 4 is disposed transversely below the two fixed plates 1 on the same side, and the lower end of the movable screw seat 5 is slidably sleeved on the guide rod 4. The setting of the guide rod 4 can limit the movable screw seat 5 so that it can move back and forth left and right as needed.

[0027] The movable screw rod 3 is composed of two screw rods welded together, and the spiral lines on the two screw rods rotate in opposite directions. When the movable screw rod 3 rotates, the two movable screw seats 5 on the left and right sides can move inward or outward at the same time, thereby making the deviation correction roller 6 move synchronously, so that the plate is placed in the middle position of the mold on the machine platform of the stamping equipment;

[0028] The right end of the movable screw rod 3 extends outward to form an extended handle 31 for facilitating the rotation of the movable screw rod 3 .

[0029] The support roller 7 is rotatably arranged on the lower bracket 71 through an axle pin, and the upper surface of the outer ring of the support roller 7 is flush with the upper surface of the mold on the punching equipment platform, thereby being able to support the left and right ends of the plate on the mold and prevent the lower pressure roller 8 from bending downward due to excessive downward pressure;

[0030] Adjustment slide holes 21 are formed on the left and right ends of the outward surface of the mounting frame 2, and a fixing screw 72 is integrally provided on the outward end of the lower bracket 71. The fixing screw 72 passes through the adjustment slide hole 21 and is placed outside the mounting frame 2, and a fixing nut 73 is threadedly connected to the fixing screw 72. After the fixing plate 1 is installed, it is difficult to ensure that the upper surface of the support roller 7 is flush with the upper surface of the mold. We place a flat plate on the upper surface of the mold, then move the support roller 7 upward, and move the outer ring surface of the support roller 7 to contact the lower surface of the flat plate. At this time, the fixing nut 73 can be tightly screwed on the fixing screw 72.

[0031] A threaded hole is installed at the top of the mounting frame 2, and the adjusting screw 82 is threadedly connected in the threaded hole, and the lower end of the adjusting screw 82 is rotatably connected to the upper bracket 81. The lower pressure roller 8 is rotatably installed on the upper bracket 81 through an axle pin, and the inner surface of the upper bracket 81 is in sliding contact with the inner surface of the mounting frame 2. The height of the lower pressure roller 8 can be changed as needed under the action of the adjusting screw 82, so that it can be pressed on the upper surface of the plate to prevent it from warping, and is suitable for plates of various thicknesses.

[0032] A circular hole is formed downwardly through the upper surface of the mounting frame 2, and the circular hole extends downward to the bottom of the mounting frame 2. The mounting shaft pin 61 is vertically arranged on the mounting frame 2 through the circular hole, and the correcting roller 6 is rotatably sleeved on the mounting shaft pin 61. The mounting shaft pin 61 includes a straight rod and a disc. The straight rod is fixed under the disc, and the disc is fixed to the top of the mounting frame 2 by screws, which facilitates the installation and disassembly of the mounting shaft pin 61, and further facilitates the installation and disassembly of the correcting roller 6.

[0033] The implementation principle of a deviation correction device for a stamping equipment in the embodiment of the present application is as follows: in actual use, the device is installed on a workbench of the stamping equipment (such as Figure 5 As shown), then adjust the height of the support roller 7 so that the upper surface of the outer ring of the support roller 7 is in the same plane as the upper end surface of the mold on the workbench of the stamping equipment. Specifically, place a flat plate on the upper surface of the mold, then move the support roller 7 upward, and move the outer ring surface of the support roller 7 to contact the lower surface of the flat plate. At this time, tighten the fixing nut 73 on the fixing screw 72, and then move the lead screw 3 to move the left and right correcting rollers 6 inward so that the left and right correcting rollers 6 can roll and contact with the two side surfaces of the plate. In this way, it can be ensured that the plate moves along the direction set by the multiple correcting rollers 6 without positional deviation, and the lower pressure roller 8 is moved downward by adjusting the screw 82, so that the lower pressure roller 8 is in rolling contact with the upper surface of the plate.

[0034] By arranging symmetrical deflection correction rollers 6 on the left and right sides of the stamping die, multiple deflection correction rollers 6 can ensure that the stamping sheet moves along the specified direction without positional deviation, and the deflection correction rollers 6 will not be deflected due to long-term use, thereby improving accuracy;

[0035] By arranging a support roller 7 on the mounting frame 2, the support roller 7 can support the stamping plate together with the mold, and can ensure that the extrusion of the lower pressure roller 8 will not cause bending at both ends of the thinner plate. In combination with the lower pressure roller 8, the two sides of the plate will not warp up, which is convenient for subsequent stamping.

[0036] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
