Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a stamping fixture. Background Technology

[0002] To ensure the normal operation of the paper machine, it is essential to maintain its integrity, thereby effectively improving the overall efficiency of the production line. When the paper machine is running, we must ensure that the roller surfaces are clean, as this facilitates paper separation and reduces the likelihood of breakage and holes. Adhesive residue and paper shavings can easily cause paper breaks and jams, resulting in significant losses for the company.

[0003] The current common solution is to install an airbag clamp, which pressurizes the cleaning roller surface. Although this airbag clamp can ensure stable airbag pressure, it is heavy and expensive due to the use of stainless steel finger clamps, which causes inconvenience to customers during installation and results in a long installation time. Utility Model Content

[0004] This utility model provides a stamping fixture to solve the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, this utility model provides a stamping fixture, including a fixture body and a blade. The fixture body includes a lower pressure plate. A plurality of small brackets distributed on the left and right are fixedly connected to the front side of the lower pressure plate by bolts. The plurality of small brackets are movably connected to a round bar. A plurality of finger-shaped clamping block assemblies distributed on the left and right are movably connected to the front side of the lower pressure plate by the round bar. A top pressure plate is riveted to the front side of the plurality of finger-shaped clamping block assemblies. The blade is clamped and fixed at the top between the finger-shaped clamping block assemblies and the top pressure plate. An adjustment mechanism is installed inside the fixture body.

[0006] Preferably, the adjustment mechanism includes two left-right distributed airbag clamps, and an open airbag and a pressurized airbag are fixedly connected between the two airbag clamps. The open airbag and the pressurized airbag are both located between the lower pressure plate and the finger clamping block assembly, and the small bracket and the round bar are both located between the open airbag and the pressurized airbag.

[0007] Preferably, one of the airbag clips has two ventilation ports fixedly connected to its outer side, and the two ventilation ports are respectively connected to the interior of the open airbag and the pressurized airbag.

[0008] Preferably, the lower pressure plate, small bracket, round bar, finger clamping block assembly, upper pressure plate, airbag clamping plate and ventilation interface are all made of stainless steel.

[0009] Compared with related technologies, the stamping fixture provided by this utility model has the following beneficial effects:

[0010] By clamping and fixing the blade with the main body of the clamp, and with the cooperation of the pressurizing airbag and the opening airbag in the adjustment mechanism, the blade can be changed while in operation. The stainless steel finger-shaped clamping block assembly is lighter and more corrosion-resistant. At the same time, due to the overall weight reduction of the clamp, the number of operators can be reduced. The clamp is highly adaptable and can be used in multiple positions. It is also cheaper and easier to promote. Attached Figure Description

[0016] Implementation examples, by Figure 1-4 The present invention includes a clamp body and a blade 5. The clamp body includes a lower pressure plate 1. A plurality of small brackets 2 distributed on the left and right are fixedly connected to the front side of the lower pressure plate 1 by bolts. The plurality of small brackets 2 are movably connected to a round rod 3. A plurality of finger-shaped clamping block assemblies 4 distributed on the left and right are movably connected to the front side of the lower pressure plate 1 by the round rod 3. The front sides of the plurality of finger-shaped clamping block assemblies 4 are riveted to an upper pressure plate 6. The blade 5 is clamped and fixed at the top between the finger-shaped clamping block assemblies 4 and the upper pressure plate 6. An adjustment mechanism is installed inside the clamp body.
