Description

Technical Field

[0001] This utility model belongs to the field of self-adhesive iron core sections, and in particular relates to a horizontal pressurization structure. Background Technology

[0002] Self-adhesive laminations typically refer to a self-adhesive lamination technology or product widely used in the manufacture of motors, generators, and other equipment. This technology primarily uses a specific bonding process to achieve strong self-bonding between laminations (usually thin sheets of silicon steel or other materials), thus forming a unified structure. After stacking, the self-adhesive laminations require pressure holding and heating, with two support plates controlling the position of the lamination segments.

[0003] Comparing with Chinese Patent CN209859796U, an electromagnet core stacking device is disclosed, comprising: two clamping plates arranged opposite each other to clamp the two ends of the stacked electromagnet core; a clamping device acting on the two clamping plates to clamp the stacked electromagnet core; and an elastic member connected to at least one clamping plate to drive the clamping plate to always press the stacked electromagnet core when the thickness of the stacked electromagnet core shrinks during the baking process. This device can press the stacked electromagnet core, apply a clamping force to the stacked electromagnet core, and simultaneously compensate for the thickness reduction of the electromagnet core during the baking process, ensuring that the clamping plate always presses the stacked electromagnet core, ultimately forming a stacked electromagnet core. In other words, this electromagnet core stacking device can produce electromagnet cores stacked using laminations.

[0004] However, the aforementioned patent uses threaded tensioning and compression for fixation, and employs elastic compensation to reduce the thickness, resulting in limited clamping force. It is difficult to guarantee stable and long-lasting pressure retention and fixation, so a new device needs to be designed. Utility Model Content

[0025] In this embodiment: the frame device includes a left end plate 101 and a right end plate 102 arranged in parallel. A fixed support plate 104 is installed in the middle between the left end plate 101 and the right end plate 102. Four tie rods 103 are evenly distributed at the four corners between the left end plate 101 and the right end plate 102. A through hole 106 is provided in the middle of the left end plate 101 for the self-adhesive section core to enter and exit. Four connecting seats 105 are evenly distributed at the four corners of the side of the left end plate 101 away from the tie rods 103. The tie rods 103 tighten and fix the left end plate 101 and the right end plate 102 together, and form a positioning frame with the fixed support plate 104 between the left end plate 101 and the right end plate 102. The self-adhesive section core is placed between the left end plate 101 and the right end plate 102 through the through hole 106 along the fixed support plate 104.

[0026] In this embodiment: the end device includes a force-applying component for hydraulic pressure application and maintenance, and a force-transmitting component for transmitting pressure and preventing strain is installed at one end of the force-applying component; the force-applying component includes a hydraulic connecting plate 201, a balance support plate 202 is provided on one side of the hydraulic connecting plate 201, six hydraulic cylinders 205 are evenly installed in the middle position between the hydraulic connecting plate 201 and the balance support plate 202, arranged in three rows and two columns, and four fixing screws 204 are evenly distributed at the four corners between the hydraulic connecting plate 201 and the balance support plate 202, with locking nuts 203 installed on the fixing screws 204; the force-transmitting component includes a pressure-pressurizing intermediate plate 207, a plurality of sliding bearings 208 are evenly distributed on the pressure-pressurizing intermediate plate 207, four guide posts and guide sleeves 206 are evenly installed around the circumference of the balance support plate 202, the balance support plate 202 and the fixing screws 204 are slidably connected, and the pressure-pressurizing intermediate plate 207 is fixedly connected to the balance support plate 202; the fixing screws 204 are respectively connected to the hydraulic cylinders 205.

Then, the pressure intermediate plate 207 is passed through the through hole 106 and the fixing screw 204 is screwed together with the corresponding connecting seat 105. At the same time, the locking nut 203 is tightened and then loosened. Then, the hydraulic cylinder 205 extends under the support of the hydraulic connecting plate 201, pushing the balance support plate 202 to move along the fixing screw 204, so that the pressure intermediate plate 207 slowly passes through the through hole 106 on the left end plate 101, contacts the self-adhesive section iron core and applies pressure.
