Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically to a continuous stamping device for intelligent machining of precision parts to prevent deformation. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, pipe, and profiles, causing plastic deformation or separation to obtain workpieces of the desired shape and size. Reducers, also known as pipe fittings, are a type of chemical pipe fitting used to connect two pipes of different diameters. They are further divided into concentric reducers and eccentric reducers. Reducers are used in industries such as petroleum, chemical, power, and metallurgy to connect pipes of different diameters, ensuring smooth fluid transmission. Their excellent mechanical properties and corrosion resistance make them outstanding in these fields.

[0003] The main production methods for reducers include two types: diameter reduction forming and diameter expansion forming. Diameter expansion forming involves using a tube blank with a diameter smaller than the large end diameter of the reducer and expanding the diameter along the inner diameter of the tube blank using an internal punch. This method is mainly used to solve the problem of reducers with large diameter changes being difficult to form by diameter reduction forming.

[0004] A search revealed a utility model patent with publication number CN216298607U, which discloses a positioning device for preventing deformation of tubular parts. The device includes a base plate, an upper plate, a mounting plate, a vertical plate, and a clamping component. The base plate has a positioning groove and a sliding groove. The upper plate is connected to the base plate via a connecting column. A power component is mounted on the upper plate. The mounting plate is movably connected to the upper plate via a push rod of the power component. A support component and a driving component are mounted on the mounting plate, both corresponding to the clamping component. The support component corresponds to the positioning groove. The clamping component is movably connected to the vertical plate via a reset component. The clamping component is symmetrical about the positioning groove. This utility model provides a positioning device for preventing deformation of tubular parts after processing, thus improving the quality of the processed tubular parts.

[0005] Although the aforementioned patent uses a clamping member that is movably connected to the vertical plate via a reset member, and the clamping member is symmetrical about the positioning groove to avoid deformation of the tubular parts after processing, thus improving the quality of the tubular parts after processing, the top expansion portion of the reducing tube will deform during the expansion forming process. The aforementioned device only uses a spring to push the clamping member to move and complete the clamping and fixing of the tubular parts. This causes the clamping member to move when it is shaken or squeezed, which makes the top expansion portion of the tubular parts prone to irregular deformation during stamping.

[0006] Therefore, it is necessary to propose a continuous stamping device for intelligent machining of precision parts to prevent deformation in order to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a precision parts intelligent continuous stamping device that prevents deformation. Through the cooperation between the internal parts of the stamping mechanism, the continuous stamping operation of the tubular parts placed on the main body of the stamping device can be completed. At the same time, through the cooperation between the internal parts of the anti-deformation mechanism, the tubular parts can be clamped and limited. During the expansion stamping, the top of the tubular parts is completely in the limiting cylinder, thus preventing deviation and deformation. This solves the problem in the prior art where the clamping and fixing of the tubular parts is completed by moving the top clamping member with a spring, which causes the top clamping member to move when shaken or squeezed, resulting in irregular deformation of the top of the tubular parts during the expansion of the diameter during stamping.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a continuous stamping device for intelligent processing of precision parts to prevent deformation, comprising a stamping device body, a stamping mechanism fixed at the top of the stamping device body, and an anti-deformation mechanism installed inside the stamping device body and located below the stamping mechanism;

[0009] The stamping mechanism includes a hydraulic telescopic rod, which is fixed to the top of the main body of the stamping device by bolts and extends to the bottom of the main body of the stamping device. A protective cover is slidably sleeved on the bottom end of the hydraulic telescopic rod, and a telescopic spring is mechanically connected between the top end of the protective cover and the bottom end of the hydraulic telescopic rod, and is sleeved with the outer wall of the hydraulic telescopic rod. A stamping head is fixed to the bottom end of the hydraulic telescopic rod by bolts and is located in the inner cavity of the protective cover. Limiting sliders are slidably connected to both sides of the outer wall of the protective cover and are located at the bottom ends of both sides of the stamping head. A connecting spring is mechanically connected between one side of the limiting slider and the inner wall of the protective cover.

[0010] The anti-deformation mechanism includes a limiting cylinder, which is rotatably connected to the upper part of the stamping device body and located directly below the protective cover and the stamping head. A support column is slidably connected to the upper part of the stamping device body, and the limiting cylinder is sleeved with the outer wall of the support column. A support spring is mechanically connected between the bottom end of the support column and the inside of the stamping device body.

[0011] Preferably, the anti-deformation mechanism further includes a transmission gear, which is fixed to the bottom of the outer wall of the limiting cylinder by bolts. A servo motor is fixed inside the main body of the stamping device by bolts. The output end of the servo motor is rotatably connected to a connecting gear through a coupling and is located on the left side of the limiting cylinder and the transmission gear.

[0012] Preferably, the main body of the stamping device has a support groove inside that matches the support column, the inner wall of the limiting cylinder is set as a conical structure, a stamping groove matching the pipe is left between the limiting cylinder and the support column, and a positioning column is mechanically fixed at the top of the support column, and the diameter of the positioning column is smaller than that of the support column.

[0013] Preferably, the main body of the stamping device has a transmission groove inside that matches the connecting gear and the transmission gear. The connecting gear and the transmission gear mesh with each other through the tooth groove. An internal battery that drives the servo motor is installed inside the main body of the stamping device.

[0014] Preferably, a hydraulic cylinder for driving the hydraulic telescopic rod is fixedly installed at the top of the main body of the stamping device, the inner cavity of the protective cover is provided with a telescopic groove that matches the stamping head, and the elastic coefficient of the telescopic spring is greater than that of the support spring.

[0015] Preferably, the bottom end of the protective cover is provided with a sliding groove that matches the limiting slider, and the contact surfaces of the limiting slider and the bottom end of the stamping head are both set as conical surfaces, and the bottom diameter of the stamping head is smaller than the inner diameter of the pipe.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. The worker places the tubular part into the limiting cylinder, and the tubular part contacts the top of the support column and is connected to the outer wall of the positioning column at the top of the support column. The hydraulic telescopic rod is activated, and the movement of the hydraulic telescopic rod drives the protective cover and the stamping head to move. The protective cover moves to contact the top of the tubular part first, and pushes the tubular part to squeeze the support column through the limiting sliders on both sides of the bottom end. The support column is forced to compress the support spring and move. The movement of the support column drives the tubular part with the top end completely into the limiting cylinder, so that the outer wall of the bottom end of the tubular part is completely in contact with the inner wall of the limiting cylinder. At the same time, the conical structure between the top end of the tubular part and the inner wall of the limiting cylinder still maintains a gap. This completes the clamping and limiting of the tubular part before stamping and prevents the tubular part from shaking and causing displacement and deformation during stamping.

[0018] 2. The hydraulic telescopic rod continues to move, driving the stamping head out from inside the protective cover and into the limiting cylinder. The protective cover, under pressure, compresses the telescopic spring, causing it to slide against the outer wall of the hydraulic telescopic rod. This keeps the bottom of the protective cover and the top of the limiting cylinder in contact. The stamping head moves, compressing the limiting slider, which in turn compresses the connecting spring, causing it to retract and release the barrier between the stamping head and the tubular part. This allows the stamping head to continue moving, penetrating through the conical surface at its bottom into the tubular part, completing the diameter expansion operation at the top of the tubular part. This causes the diameter expansion deformation at the top of the tubular part to fit against the conical structure on the inner wall of the limiting cylinder. The servo motor is then activated, driving the connecting gear to rotate. This rotation drives the transmission gear, which in turn rotates the limiting cylinder. The rotating limiting cylinder then grinds the outer wall of the tubular part through its inner cavity and shapes the subtle deformation caused by the diameter expansion at the top of the tubular part, thus improving the quality of the tubular part's stamping and diameter expansion.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-4 The precision parts intelligent continuous stamping device shown includes a stamping device body 1, a stamping mechanism 2 fixed at the top of the stamping device body 1, and an anti-deformation mechanism 3 installed inside the stamping device body 1 and located below the stamping mechanism 2.

[0028] The stamping mechanism 2 includes a hydraulic telescopic rod 201, which is fixed to the top of the stamping device body 1 by bolts and extends to the bottom of the stamping device body 1. A protective cover 203 is slidably sleeved on the bottom end of the hydraulic telescopic rod 201, and a telescopic spring 202 is mechanically connected between the top end of the protective cover 203 and the bottom end of the hydraulic telescopic rod 201 and sleeved with the outer wall of the hydraulic telescopic rod 201. A stamping head 204 is fixed to the bottom end of the hydraulic telescopic rod 201 by bolts and is located in the inner cavity of the protective cover 203. Limiting sliders 205 are slidably connected on both sides of the outer wall of the protective cover 203 and are located at the bottom ends of both sides of the stamping head 204. A connecting spring 206 is mechanically connected between one side of the limiting slider 205 and the inner wall of the protective cover 203.

[0029] The anti-deformation mechanism 3 includes a limiting cylinder 301, which is rotatably connected to the upper part of the stamping device body 1 and located directly below the protective cover 203 and the stamping head 204. A support column 302 is slidably connected to the upper part of the stamping device body 1, and the limiting cylinder 301 is sleeved with the outer wall of the support column 302. A support spring 303 is mechanically connected between the bottom end of the support column 302 and the interior of the stamping device body 1.

[0030] Through the cooperation between the internal parts of the stamping mechanism 2, the tubular parts placed on the main body 1 of the stamping device can be continuously stamped. At the same time, through the cooperation between the internal parts of the anti-deformation mechanism 3, the tubular parts can be clamped and limited. The top of the tubular parts is completely in the limiting cylinder 301 during the expansion stamping, thus preventing deviation and deformation.

[0031] Refer to the instruction manual appendix Figure 1-4 The anti-deformation mechanism 3 also includes a transmission gear 304, which is fixed to the bottom of the outer wall of the limiting cylinder 301 by bolts. The servo motor 305 is fixed inside the main body 1 of the stamping device by bolts. The output end of the servo motor 305 is rotatably connected to the connecting gear 306 through a coupling and is located on the left side of the limiting cylinder 301 and the transmission gear 304. Through the mutual cooperation between the internal parts of the anti-deformation mechanism 3, it is convenient to polish the outer wall of the tubular part after the tubular part is stamped, thereby reducing the burrs on the outer wall of the tubular part.

[0032] Refer to the instruction manual appendix Figure 1-4The main body 1 of the stamping device has a support groove inside that matches the support column 302. The inner wall of the limiting cylinder 301 is set as a conical structure. There is a stamping groove between the limiting cylinder 301 and the support column 302 that matches the pipe fitting. The top of the support column 302 is mechanically fixed with a positioning column, and the diameter of the positioning column is smaller than that of the support column 302. The inner wall of the limiting cylinder 301 is set as a conical structure. There is a stamping groove between the limiting cylinder 301 and the support column 302 that matches the pipe fitting. The top of the support column 302 is mechanically fixed with a positioning column, and the diameter of the positioning column is smaller than that of the support column 302. This makes it easy for the support column 302 to complete the fitting of the tubular part through the positioning column at the top and drive the tubular part to move into the inner cavity of the limiting cylinder 301 to complete the diameter expansion operation.

[0033] Refer to the instruction manual appendix Figure 1-4 The stamping device body 1 has a transmission groove inside that matches the connecting gear 306 and the transmission gear 304. The connecting gear 306 and the transmission gear 304 mesh with each other through the tooth groove. The stamping device body 1 has an internal battery installed inside that drives the servo motor 305. The transmission groove inside the stamping device body 1 that matches the connecting gear 306 and the transmission gear 304 meshes with each other through the tooth groove, which facilitates the servo motor 305 to drive the connecting gear 306 to rotate, thereby driving the transmission gear 304 to rotate.

[0034] Refer to the instruction manual appendix Figure 1-4 The top of the main body 1 of the stamping device is fixed with a hydraulic cylinder that drives the hydraulic telescopic rod 201. The inner cavity of the protective cover 203 is provided with a telescopic groove that matches the stamping head 204. The elastic coefficient of the telescopic spring 202 is greater than that of the support spring 303. The telescopic groove provided in the inner cavity of the protective cover 203 matches the stamping head 204. The elastic coefficient of the telescopic spring 202 is greater than that of the support spring 303, which facilitates the movement of the protective cover 203 to contact the top of the tubular part. The bottom of the protective cover 203 is in contact with the top of the limiting cylinder 301.

[0035] Refer to the instruction manual appendix Figure 1-4 The bottom end of the protective cover 203 is provided with a sliding groove that matches the limiting slider 205. The contact surfaces of the limiting slider 205 and the bottom end of the punch head 204 are both set as conical surfaces. The bottom diameter of the punch head 204 is smaller than the inner diameter of the tube. The sliding groove at the bottom end of the protective cover 203 that matches the limiting slider 205 and the contact surfaces of the limiting slider 205 and the bottom end of the punch head 204 are both set as conical surfaces make it easier for the limiting slider 205 to move and release the obstruction between the punch head 204 and the tubular part when the punch head 204 moves out of the protective cover 203.

[0036] The working principle of this practical application is as follows:

[0037] Refer to the instruction manual appendix Figure 1-4 The tubular part is placed in the limiting cylinder 301 by the staff. The tubular part contacts the top of the support column 302 and is sleeved with the outer wall of the positioning column at the top of the support column 302. The hydraulic telescopic rod 201 is activated. The movement of the hydraulic telescopic rod 201 drives the protective cover 203 and the stamping head 204 to move. The protective cover 203 moves to contact the top of the tubular part first. The limiting sliders 205 on both sides of the bottom end push the tubular part to squeeze the support column 302. The support column 302 is forced to compress the support spring 303 and move. The movement of the support column 302 drives the tubular part sleeved at the top to move completely into the limiting cylinder 301. The outer wall of the bottom end of the tubular part is completely in contact with the inner wall of the limiting cylinder 301. At the same time, the conical structure between the top of the tubular part and the inner wall of the limiting cylinder 301 still maintains a gap. This completes the clamping and limiting of the tubular part before stamping and prevents the tubular part from shaking and deforming during stamping.

[0038] Refer to the instruction manual appendix Figure 1-4 The hydraulic telescopic rod 201 continues to move, driving the punch head 204 to move out of the protective cover 203 and into the limiting cylinder 301. Meanwhile, the protective cover 203, under pressure, compresses the telescopic spring 202, causing it to slide against the outer wall of the hydraulic telescopic rod 201, keeping the bottom of the protective cover 203 and the top of the limiting cylinder 301 in contact. The punch head 204 moves, compressing the limiting slider 205, which in turn compresses the connecting spring 206, causing the limiting slider 205 to release the barrier between the punch head 204 and the tubular part. This allows the punch head 204 to continue moving, penetrating through the conical surface at its bottom into the tubular part, completing the diameter expansion operation at the top of the tubular part. This causes the top of the tubular part to deform and engage with the limiting cylinder 301. 1. The conical structure on the inner wall of the top edge fits in place. The servo motor 305 is started, and the servo motor 305 drives the connecting gear 306 to rotate. The rotation of the connecting gear 306 drives the transmission gear 304 to rotate, and the rotation of the transmission gear 304 drives the limiting cylinder 301 to rotate. The rotation of the limiting cylinder 301 passes through the inner cavity to grind the outer wall of the tubular part and to shape the slight deformation caused by the expansion of the diameter at the top of the tubular part. This improves the quality of the tubular part's stamping and expansion. After the hydraulic telescopic rod 201 retracts and moves to release the pressure on the tubular part, the support column 302 moves upward under the push of the support spring 303. The support column 302 pushes the stamped tubular part out of the limiting cylinder 301, making it easier for the staff to replace the tubular part.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
