Hydraulic clamping device for batch plates

Abstract

The invention relates to a hydraulic clamping device for batch plates, and belongs to the processing machinery of plate samples. The hydraulic clamping device is characterized in that: a rolling-over shaft and a rolling-over oil cylinder are arranged on a clamping base; the rolling-over shaft is connected with the rolling-over oil cylinder; two fixed jaws which are arranged oppositely are arranged on the rolling-over shaft and can realize the rolling-over of 90 degrees; a movable jaw is arranged on the fixed jaw on one side; a clamping oil cylinder is arranged on the fixed jaws, is positioned below the movable jaw and is connected with the movable jaw; the fixed jaws and the movable jaw are provided with gaps matched with a band saw; and a floating pressure head is arranged on the movable jaw. The device realizes the full clamping, steering and positioning of the batch plates, completes the continuous cutting and forming of the plate samples by matching with a band saw cutting device, and has the characteristics of reasonable structure, high operational efficiency and machining accuracy, little material loss and low cost of the samples.

Description

technical field [0001] The invention belongs to a plate sample processing machine, and mainly relates to a batch plate clamping device on the plate sample processing equipment. Background technique [0002] In order to ensure the production quality of steel plates, iron and steel production enterprises need to test the physical properties of each batch of steel plates produced and processed. The test samples include tensile samples, cold-bending samples, impact samples and other plate samples. Production, for a steel company with an annual output of 1 million tons, its annual inspection batches reach as many as 130,000 times. Obviously, the workload of producing plate samples is very huge. At present, it is more common to use ordinary band sawing machines or circular sawing machines to directly process plates to obtain plate samples. However, due to the structural defects of the processing equipment, it is not only impossible to process sheet metal samples in batches, but th...

Problems solved by technology

At present, it is more common to use ordinary band sawing machines or circular sawing machines to directly process plates to obtain plate samples. However, due to the structural defects of the processing equipment, it is not only impossible to process sheet metal samples in batches, but the work efficiency is low. The production cost is increased, and the precision of the processed sample is poor, which does not meet the requirements of physical performance testing, resulting in huge loss and waste
