Description

Technical Field

[0001] This utility model relates to the technical field of thermal protector component processing equipment, and in particular to a thermal protector bimetallic strip processing machine. Background Technology

[0002] The production process of thermal protectors requires the processing of bimetallic strips of specific specifications, which are usually formed by stamping equipment.

[0003] Currently, the stamping equipment used to process this type of sheet often leaves the formed bimetallic sheet in the stamping hole of the bottom die after the stamping process is completed. Operators need to manually remove the sheet one by one. This material removal method consumes a lot of time. Although some equipment has tried to add an automatic feeding mechanism, there are problems such as structural redundancy and large space occupation.

[0004] To address the aforementioned problems, this utility model document proposes a bimetallic strip processing machine for thermal protectors. Utility Model Content

[0005] This utility model provides a bimetallic sheet processing machine for thermal protectors, which solves the problem in the prior art that after the stamping process is completed, the formed bimetallic sheet often remains in the stamping hole of the bottom die, requiring the operator to manually remove the sheet one by one. This material removal method consumes a lot of time. Although some equipment has tried to add an automatic feeding mechanism, it has disadvantages such as structural redundancy and large space occupation.

[0006] This utility model provides the following technical solution: A bimetallic strip processing machine for thermal protectors, comprising: The machine frame has a top frame fixedly installed on its top. A pressure plate is vertically slidably installed inside the top frame. A top mold with a top block is fixed to the bottom of the pressure plate by bolts. A bottom mold with a punching hole is installed below the top mold. Two support blocks are symmetrically fixedly installed on the bottom of the bottom mold. The bottom of the two support blocks is fixedly connected to the top of the machine frame. A push plate for ejecting the formed material is installed between the two support blocks. The bottom of the push plate is slidably connected to the top of the machine frame. A material collection box is detachably installed at the front end of the machine frame.

[0007] In one possible design, a hydraulic cylinder is fixedly installed at the center of the top of the top frame. The output end of the hydraulic cylinder slides through the top of the inner wall of the top frame and is fixedly connected to the center of the top of the pressure plate. Two guide rods I are symmetrically fixedly arranged on the top of the pressure plate. The top of the top frame is provided with sliding holes for sliding connection of the corresponding guide rods I.

[0008] In one possible design, guide rods II are provided at the four corners of the top of the bottom mold, sliding holes for sliding connection of the corresponding guide rods II are provided at the four corners of the pressure plate, internal thread grooves are provided at the four corners of the top of the bottom mold, and external threads that are adapted to the internal thread grooves are provided on the lower edge of the outer wall of the guide rods II.

[0009] In one possible design, a hydraulic station is installed inside the frame, and both delivery pipes of the hydraulic cylinder are connected to ports on the hydraulic station.

[0010] In one possible design, a mounting plate is fixedly installed at the rear end of the frame, and an electric push rod is fixedly installed on the outer wall of the mounting plate. The output end of the electric push rod slides through the inner wall of the mounting plate and is fixedly connected to the center of the outer wall of the push plate.

[0011] In one possible design, downward-facing L-shaped locking blocks are fixedly installed on both sides of the outer wall of the collection box, and a rectangular hollow locking seat for locking the bottom end of the corresponding L-shaped locking block is fixedly installed at the front end of the frame.

[0012] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0013] The working principle and usage process of this technical solution are as follows: In use, first fix the top die (with top block) of the bimetallic strip compatible with the thermal protector to the bottom of the pressure plate with bolts. Then fix the bottom die (with punching holes) to the top of the frame with the support block. The outer wall of the support block is fixed to the top of the frame with bolts to ensure that the punching positions of the top die and the bottom die are aligned. Install the four guide rods II by matching the external thread of the guide rod II with the internal thread groove of the bottom die. Then place the bimetallic strip (or sheet) to be processed above the punching hole of the bottom die, ensuring that the material covers the punching hole and is centered (external feeding can be used). The mechanism assists in positioning (the feeding structure is not limited and can be adapted to manual or automated feeding). The hydraulic cylinder receives power from the hydraulic station and pushes the pressure plate downward at the output end. At this time, the guide rod I at the top of the pressure plate slides vertically along the sliding hole of the top frame, and the sliding holes at the four corners of the pressure plate slide along the guide rod II at the top of the bottom mold. The double guidance ensures that the pressure plate descends vertically and avoids the top mold from shifting. The pressure plate drives the bottom top mold to move downward. The top block of the top mold presses the bimetallic raw material into the punching hole of the bottom mold. The bimetallic sheet is formed by the shape of the punching hole, and the stamping process is completed. After stamping is completed, the hydraulic cylinder drives the pressure plate and the top die to return to their original positions. At this time, the electric push rod on the mounting plate at the rear end of the frame is activated, and the output end pushes the push plate forward. The push plate slides along the top of the frame, passes between the two support blocks, and pushes the bimetallic sheet formed in the bottom die stamping hole forward. The pushed-out sheet slides forward along the top of the frame and falls directly into the collection box at the front of the frame, realizing the centralized collection of the sheet. When the collection box is full, the collection box can be lifted up, so that its L-shaped locking block disengages from the rectangular hollow locking seat of the frame, completing the disassembly of the collection box and the transfer of the sheet. After emptying, it can be re-locked and used again without stopping the machine to disassemble the complex structure.

[0014] This utility model has the following beneficial effects: This utility model achieves material collection through a push plate and a detachable collection box. The push plate feeds the material into the collection box, which can be quickly disassembled or installed without tools through an L-shaped locking block and a locking seat.

[0015] This utility model adopts a dual guiding structure, with guide rod I between the pressure plate and the top frame and guide rod II between the pressure plate and the bottom mold, ensuring that the pressure plate drives the top mold to rise and fall vertically, avoiding deviation during the stamping process; the support blocks symmetrically fix the bottom mold, which not only ensures the stability of the bottom mold, but also reserves sliding space for the push plate, and the overall structure is relatively compact.

The top frame 2 is a U-shaped frame structure made of 6061 aluminum alloy. Vertical guide grooves are provided on both sides of its inner wall. The pressure plate 4 is vertically slidably connected by sliding blocks on both sides embedded in the guide grooves. The top center of the top frame 2 is fixedly connected to the hydraulic cylinder 3 via a flange. The hydraulic cylinder 3 is a CD250 series single-rod double-acting hydraulic cylinder. Its output end passes through a through hole at the top of the top frame 2 and is welded to the top center of the pressure plate 4 via a bushing. The pressure plate 4 is a rectangular plate made of 45# steel. Two guide rods I5 are symmetrically welded to its top. The guide rods I5 are 45# steel round rods. Two sliding holes are provided at the top of the top frame 2. The guide rods I5 pass through the sliding holes and are clearance-fitted with them.

[0022] The top mold 6 is fixed to the bottom of the pressure plate 4 by four internal hex bolts. The top mold 6 is made of Cr12MoV mold steel. The shape of the top block at the bottom is designed according to the specifications of the target bimetallic sheet. In this embodiment, the top block is a cylindrical structure. The bottom mold 7 set below the top mold 6 is also made of Cr12MoV mold steel. Its top has a stamping hole that matches the top block. Two support blocks 8 are symmetrically welded to the bottom of the bottom mold 7. The support blocks 8 are 45# steel square blocks. The bottom of the two support blocks 8 are fixed to the top of the frame 1 by expansion bolts.

[0023] The bottom mold 7 has internal threaded grooves 10 at each of the four corners. The guide rod II 9 is a No. 45 steel round rod with external threads 11 that are compatible with the internal threaded grooves 10 on its lower outer wall. During installation, the guide rod II 9 is screwed into the internal threaded grooves 10 until the bottom fits against the top of the bottom mold 7, forming a vertical support structure. The pressure plate 4 has sliding holes at the four corners. The guide rod II 9 passes through the sliding holes and is fitted with the sliding holes with a clearance, forming a double guide structure together with the guide rod I 5.

[0024] The frame 1 has a pre-reserved installation cavity, and the hydraulic station 12 is fixedly installed by the angle steel bracket. The hydraulic station 12 is a YCY series small hydraulic station. Its oil outlet and oil return port are respectively connected to the two delivery pipes of the hydraulic cylinder 3 through high pressure hoses. The high pressure hose is a DN10 steel wire braided hose to ensure that the hose can move synchronously with the output end when the hydraulic cylinder 3 is activated.

[0025] The mounting plate 14 is fixedly installed at the rear end of the frame 1 by bolts. The mounting plate 14 is made of Q235 steel plate. An electric push rod 15 is fixedly installed at the center of its outer wall by bolts. The electric push rod 15 is a DT series electric push rod. Its output end passes through the through hole on the mounting plate 14 and is fixedly connected to the center of the outer wall of the push plate 13 by a coupling. The push plate 13 is a rectangular plate of No. 45 steel. A polytetrafluoroethylene wear-resistant layer is pasted on the bottom to reduce the sliding friction coefficient with the top of the frame 1. The initial position of the push plate 13 is located behind the two support blocks 8.

[0026] Rectangular hollow card seats 18 are welded to both sides of the front end of the frame 1. The rectangular hollow card seats 18 are made of stainless steel plate by bending. The collection box 16 is a rectangular box made of PP material. The outer walls of the box have downward-facing L-shaped card blocks 17 integrally injection molded on both sides. During installation, the horizontal section of the L-shaped card block 17 is inserted into the cavity of the rectangular hollow card seat 18 to achieve detachable fixing of the collection box 16. The top opening of the collection box 16 is aligned with the push path of the push plate 13 to ensure that the material can fall in smoothly.

[0027] In actual operation, first adjust the equipment level using the support feet at the bottom of the frame 1, and check whether the connections of each component are secure. Then, install the mold. Fix the top mold 6 to the bottom of the pressure plate 4 with M8 hex bolts, ensuring that the top block of the top mold 6 is centered. Place the bottom mold 7 at the corresponding position on the top of the frame 1, so that the bottom mold 7 is directly below the top mold 6. Fix the bottom mold 7 with the M10 expansion bolts at the bottom of the support block 8. Then, screw the guide rod II 9 into the internal thread groove 10 at the top of the bottom mold 7 until the guide rod II 9 is vertically fixed. Connect the high-pressure hose of the hydraulic station 12 and the hydraulic cylinder 3, and check whether the coupling between the electric push rod 15 and the push plate 13 is tight. Finally, insert the L-shaped clamping block 17 of the collection box 16 into the rectangular hollow clamping seat 18 to complete the equipment debugging. During processing, the bimetallic strip to be processed is cut into sheets and manually placed above the punching holes of the bottom die 7, ensuring that the sheets completely cover the punching holes and that the edges are aligned with the positioning lines of the bottom die 7. The hydraulic station 12 is then started, supplying oil to the hydraulic cylinder 3 through a high-pressure hose. The output end of the hydraulic cylinder 3 pushes the pressure plate 4 downward. At this time, the guide rod I5 slides downward along the sliding hole of the top frame 2, and the sliding holes at the four corners of the pressure plate 4 slide synchronously along the guide rod II9, causing the top die 6 to move vertically downward. The top block of the top die 6 presses the bimetallic strip downward. The sheet material is pressed into the punching hole of the bottom mold 7, and the forming is completed after maintaining the pressure for 3 seconds. Then, the hydraulic station 12 switches the oil circuit, and the output end of the hydraulic cylinder 3 drives the pressure plate 4 and the top mold 6 to reset upward. After resetting to the initial position, the electric push rod 15 starts, and the output end pushes the push plate 13 forward. The push plate 13 slides along the top of the frame 1, passes through the gap between the two support blocks 8, and pushes the formed bimetallic sheet in the punching hole of the bottom mold 7 forward. The sheet material slides along the top of the frame 1 and falls into the collection box 16, which is convenient to use.

[0028] This application can be used for the processing of bimetallic strips for thermal protectors, and can also be used in other fields applicable to this application.
