Description

Technical Field

[0001] This utility model relates to the field of steel bending technology, specifically to a steel bending processing equipment with quick mold changing capability. Background Technology

[0002] Steel refers to the final steel product produced by an enterprise using qualified steel materials (including steel ingots, steel billets, and steel products) and having completed the entire steel production process, after passing inspection. Steel often requires bending equipment for bending operations during processing. In the prior art, patent CN 117046933 A discloses a steel bending device for processing vehicle parts, including a machine body. Two work boxes are located on the top of the machine body, positioned on either side. A pressing block is mounted on the front of the machine body, and an upper die is mounted on the bottom of the pressing block. This invention addresses the problem of common methods for limiting impact force, including reducing the speed of movement by applying resistance during descent and extending the impact time using a buffer structure. These solutions either generate a large amount of heat during operation that is difficult to dissipate and may fail, or they cannot directly and quickly stop the device from working immediately. Therefore, this invention addresses the problem of a steel bending device for processing vehicle parts. In this invention, by rotating... The use of replacement part one and conversion part two converts the torque of the vertical movement of the pressing block and the upper die into torque. The working state of the pressing block and the upper die can then be controlled by controlling the torque. The upper dies in this device are all installed and fixed by locking bolts on the corresponding mounting bases. The number of upper dies in the bending equipment usually depends on the processing requirements and specifications of the steel. Therefore, a single bending equipment usually has multiple upper dies. Since different types of bending operations of steel require different upper dies, the upper dies in this device are all fixed by bolts, which leads to a lot of time spent on bolt disassembly and assembly during the upper die replacement process. There is room for improvement. Therefore, we propose a steel bending processing equipment with quick die replacement. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a steel bending processing equipment with quick mold change. The device, through transmission elements, utilizes inclined dovetail groove extrusion guidance and thread transmission to simultaneously perform limit release or lock limit operations on the installation limit components of each upper die. This eliminates the need for workers to disassemble and assemble the corresponding mounting bolts on each upper die, thereby shortening the mold change time required for the steel bending processing equipment and effectively solving the problems in the background art.

An adjusting base is provided between the guide rods. A locking assembly is provided between the adjusting base, the lower pressure seat, and the upper die. An adjusting assembly is provided between the fixed base and the adjusting base. This device, through a transmission element, utilizes oblique dovetail groove extrusion guidance and threaded transmission to simultaneously perform limit release or locking limit operations on the installation limit components of each upper die.

The laser sensor is bidirectionally electrically connected to the microcontroller to control the vertical movement distance of the upper die in the steel bending processing equipment with quick die change.

[0008] Furthermore, the locking assembly includes a fixed base II, a longitudinal sliding base, an extrusion base, a limiting groove, an oblique dovetail groove, a slide block, a corner bracket, and a connecting rod. The fixed base II is horizontally and evenly arranged at the lower front end of the lower pressure base. Each fixed base II has a horizontally symmetrically distributed dovetail groove II inside. A longitudinal sliding base is slidably connected between two horizontally adjacent dovetail groove IIs. An extrusion base is provided on the rear side of each longitudinal sliding base.

An oblique dovetail groove is provided in the middle of the front side of each longitudinal sliding base. A slide block is slidably connected inside each oblique dovetail groove. A connecting rod is provided on the upper side of each slide block through a corner bracket. The upper end of each connecting rod is fixedly connected to the lower side of the adjusting base, thereby performing extrusion locking and limiting on the corresponding upper die in the steel bending processing equipment with quick die change.

[0009] Furthermore, the locking assembly also includes rubber pads, which are respectively disposed on the rear side of the extrusion seat to improve the extrusion contact friction between the extrusion seat and the corresponding limiting groove in the steel bending processing equipment with quick mold change.

[0010] Furthermore, the adjustment assembly includes a threaded cylinder, a stud, and a handwheel. The threaded cylinder is located in the upper middle part of the adjustment seat. The stud is rotatably connected to the middle part of the fixed seat through a bearing. The lower end of the stud is threadedly connected to the threaded cylinder. The upper end of the stud is provided with a handwheel to provide power for adjusting the installation limit of multiple upper dies in the steel bending processing equipment with quick die change.

[0011] Furthermore, the adjustment component also includes a bellows, which is disposed between the fixed base and the threaded cylinder. The bellows is movably sleeved on the outer end of the stud to wrap and seal the stud in the steel bending processing equipment with quick mold change.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This embodiment provides a technical solution: a steel bending processing equipment with quick mold changing capability, including a processing table 1, a connecting seat 3 on the upper side of the processing table 1, a lower pressure seat 4 slidably connected in a dovetail groove on the front side of the connecting seat 3, an upper mold 9 slidably connected in an installation groove 8 on the lower front side of the lower pressure seat 4, a lower mold 10 on the upper front end of the processing table 1, and a single-chip microcomputer 2 located outside the processing table 1. The input end of the single-chip microcomputer 2 is electrically connected to an external power supply. An electro-hydraulic push rod 5 is provided on the upper side of the connecting seat 3. The telescopic end of the electro-hydraulic push rod 5 is fixedly connected to the upper rear end of the lower pressure seat 4. The input end of the electro-hydraulic push rod 5 is electrically connected to the output end of the single-chip microcomputer 2. A laser sensor 6 is provided on the left side of the lower pressure seat 4. The laser sensor 6 is bidirectionally electrically connected to the single-chip microcomputer 2. When using the device to bend steel, the worker holds the steel and places it into the lower die 10. Then, the microcontroller 2 activates the electro-hydraulic push rod 5, causing its telescopic end to drive the lower pressure seat 4 to move vertically downward along the dovetail groove on the connecting seat 3. The connecting seat 3 drives the upper die 9 to move vertically downward through the die-changing mechanism 7. At the same time, the microcontroller 2 activates the laser sensor 6, which emits a light signal to illuminate the upper side of the lower die 10 and reflects it back to the initial position. The downward movement distance of the upper die 9 is obtained based on the propagation time and speed of the light signal, and the detection result is transmitted to the microcontroller 2 in the form of an electrical signal. The microcontroller 2 adjusts the telescopic end of the electro-hydraulic push rod 5 according to this result, so that the upper die 9 is pressed down a specified distance and cooperates with the lower die 10 to perform the bending operation of the steel into the corresponding shape. The device also includes the die-changing mechanism 7.

[0022] The mold changing mechanism 7 includes a fixed base 71, guide rods 72, adjusting base 73, locking assembly 74, and adjusting assembly 75. The fixed base 71 is located at the lower front end of the lower pressure seat 4. Guide rods 72 are slidably connected to a circular hole inside the fixed base 71. Adjusting bases 73 are provided between the guide rods 72. Locking assembly 74 is provided between adjusting base 73, lower pressure seat 4, and upper mold 9. Adjusting assembly 75 is provided between fixed base 71 and adjusting base 73. The locking assembly 74 includes a fixed base 741, a longitudinal sliding base 742, an extrusion base 743, a limiting groove 745, an inclined dovetail groove 746, a sliding base 747, a corner bracket 748, and a connecting rod 749. The fixed bases 741 are horizontally and evenly arranged at the lower front end of the lower pressure seat 4. At the end, each of the fixed seats 741 has symmetrically distributed dovetail grooves 2. A longitudinal moving seat 742 is slidably connected between each pair of adjacent dovetail grooves 2. Each longitudinal moving seat 742 has an extrusion seat 743 on its rear side. Each of the upper front sides of the upper die 9 has a limit groove 745, which is installed in conjunction with the adjacent extrusion seat 743. Each of the longitudinal moving seats 742 has an oblique dovetail groove 746 in the middle of its front side. Each oblique dovetail groove 746 has a sliding seat 747 slidably connected inside its oblique dovetail groove 747. Each sliding seat 747 has a connecting rod 749 on its upper side via a bracket 748. The upper end of each connecting rod 749 is fixedly connected to the lower side of the adjusting seat 73. The locking assembly 74 also includes rubber pads 744, which are respectively disposed on the extrusion seats 743. The rear adjustment assembly 75 includes a threaded cylinder 751, a stud 752, and a handwheel 753. The threaded cylinder 751 is located in the upper middle part of the adjustment seat 73. The stud 752 is rotatably connected to the middle part of the fixed seat 71 via a bearing. The lower end of the stud 752 is threadedly connected to the threaded cylinder 751, and the upper end of the stud 752 is equipped with a handwheel 753. The adjustment assembly 75 also includes a bellows 754, which is located between the fixed seat 71 and the threaded cylinder 751. The bellows 754 is movably sleeved on the outer end of the stud 752. When changing the upper mold, the operator rotates the handwheel 753 clockwise to make the stud 752 rotate clockwise. During the clockwise rotation of the stud 752, it is threadedly connected to the threaded cylinder 751, thereby causing the threaded cylinder 751 to rotate. The adjusting seat 73 moves vertically downwards, and the adjusting seat 73 drives the sliding seat 747 to move vertically downwards synchronously via the connecting rod 749 and the corner bracket 748 (during the vertical movement of the adjusting seat 73, the guide rod 72 slides adaptively along the corresponding circular hole one, and the vertical stability of the adjusting seat 73 is improved by the sliding engagement between the guide rod 72 and the circular hole one). During the vertical downward movement of the sliding seat 747, through its sliding connection with the oblique dovetail groove 746 on the corresponding longitudinal moving seat 742, the longitudinal moving seat 742 moves forward longitudinally along the dovetail groove two on the corresponding fixed seat two 741. The longitudinal moving seat 742 drives the corresponding extrusion seat 743 to move forward longitudinally synchronously. The extrusion seat 743 releases the insertion extrusion limit on the inner limiting groove 745 of the upper die 9 by moving forward longitudinally.The device only requires a forward rotation of handwheel 753 to release the longitudinal forward movement limit of all extrusion seats 743. Then, the operator slides the upper die 9 horizontally along the mounting groove 8, separating it from the lower pressure seat 4. Next, the operator arranges the replaced upper dies 9 according to the corresponding steel bending sequence and slides them horizontally along the mounting groove 8 into the corresponding bending positions at the lower end of the lower pressure seat 4. Then, the operator rotates handwheel 753 in reverse, causing the longitudinal moving seat 742 to move longitudinally backward along the dovetail groove 2 on the corresponding fixed seat 741. The longitudinal moving seat 742 drives the corresponding extrusion seat 743 to engage with the limiting groove 745 in the corresponding upper die 9 through longitudinal backward movement, thus limiting the extrusion along the mounting groove 8. The sliding mechanism simultaneously limits the movement. The adhesiveness and elasticity of the rubber pad 744 increase the contact friction between the extrusion seat 743 and the limiting groove 745, further improving the fixing effect on the upper die 9. The bellows 754, a corrugated structure made of multiple layers of laminated metal sheets, encapsulates and lubricates the stud 752. Its working principle is to achieve self-adaptive sealing through elastic deformation to maintain good sealing performance. Through a transmission element, utilizing the oblique dovetail groove 746 for extrusion guidance and threaded transmission, the device can simultaneously release or lock the limiting components of each upper die 9, eliminating the need for workers to individually disassemble and assemble the corresponding mounting bolts on each upper die 9, thus shortening the die-changing time required for steel bending equipment.

[0023] The working principle of the quick-change steel bending processing equipment provided by this utility model is as follows: When using the device to bend steel, the operator holds the steel and places it into the lower die 10. Then, the microcontroller 2 activates the electro-hydraulic push rod 5, causing its telescopic end to drive the lower pressure seat 4 to move vertically downward along the dovetail groove on the connecting seat 3. The connecting seat 3 drives the upper die 9 to move vertically downward through the die-changing mechanism 7. At the same time, the microcontroller 2 activates the laser sensor 6, which emits a light signal that irradiates the upper side of the lower die 10 and reflects back to the initial position. The downward movement distance of the upper die 9 is obtained based on the propagation time and speed of the light signal, and the detection result is transmitted to the microcontroller 2 in the form of an electrical signal. The microcontroller 2 adjusts the telescopic end of the electro-hydraulic push rod 5 according to this result, so that the upper die 9 is pressed down to the specified position. The upper die is positioned at a distance and engages with the lower die 10 to perform bending operations on the steel to the corresponding shape. When changing the upper die, the operator rotates the handwheel 753 clockwise to drive the stud 752 to rotate clockwise. During the clockwise rotation of the stud 752, it connects with the threaded cylinder 751, causing the threaded cylinder 751 to drive the adjusting seat 73 to move vertically downward. The adjusting seat 73, through the connecting rod 749 and the angle bracket 748, drives the slide 747 to move vertically downward synchronously (during the vertical movement of the adjusting seat 73, the guide rod 72 slides adaptively along the corresponding circular hole 1, and the sliding engagement between the guide rod 72 and the circular hole 1 improves the vertical stability of the adjusting seat 73). During the vertical downward movement of the slide 747, it slides through the oblique dovetail groove 746 on the corresponding longitudinal moving seat 742. This causes the longitudinal shift seat 742 to move forward longitudinally along the dovetail groove 2 on the corresponding fixed seat 741. The longitudinal shift seat 742 drives the corresponding extrusion seat 743 to move forward longitudinally simultaneously. The extrusion seat 743 releases the insertion extrusion limit on the inner limiting groove 745 of the upper die 9 by moving forward longitudinally. The device only needs to turn the handwheel 753 forward to realize the longitudinal forward movement limit release operation of all extrusion seats 743. Then, the operator slides the upper die 9 horizontally along the mounting groove 8 to separate it from the lower pressure seat 4. Then, the operator arranges the multiple upper dies 9 installed with the corresponding steel bending sequence and slides them horizontally along the mounting groove 8 into the corresponding bending position at the lower end of the lower pressure seat 4 in the corresponding bending sequence. Then, the operator turns the handwheel 753 in reverse to release the insertion extrusion limit on the upper die 9. Using the same principle, the longitudinal shift seat 742 moves longitudinally backward along the dovetail groove 2 on the corresponding fixed seat 741. The longitudinal shift seat 742 drives the corresponding extrusion seat 743 to move longitudinally backward and thus insert into the limiting groove 745 in the corresponding upper die 9 for extrusion and limiting. This limits the sliding of multiple upper dies 9 along the mounting groove 8. Through the adhesiveness and elasticity of the rubber pad 744, the contact friction between the extrusion seat 743 and the limiting groove 745 is increased, further improving the fixing effect of the upper die 9. The stud 752 is wrapped, sealed and lubricated by the bellows 754. The bellows 754 is a corrugated structure made of multiple layers of metal sheets. Its working principle is to achieve self-adaptive sealing through elastic deformation to maintain good sealing performance.

[0024] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an MCS-51, the electro-hydraulic actuator 5 can be a DYTZB1000-500, and the laser sensor 6 can be a WH-LRF laser rangefinder. The microcontroller 2 controls the operation of the electro-hydraulic actuator 5 and the laser sensor 6 using methods commonly used in the prior art.
