Sliding block type plate feeding device

Abstract

The invention provides a sliding block type plate feeding device and belongs to the technical field of machining. The sliding block type plating feeding device comprises an upper feeding roller, a lower feeding roller, a swing bracket, a reset spring, a sliding block, a connecting rod and a crankshaft. The lower feeding roller is rotationally arranged on a base. The right end of the swing bracket is hinged to a fixed hinge support. The reset spring is arranged between the swing bracket and the base. The upper feeding roller is rotationally arranged on the swing bracket. A hinge ball head at the right end of a connecting bracket is hinged to the left end of the swing bracket. The left end of the connecting bracket is hinged to a bracket base. The sliding block is arranged on a guide rail of a sliding frame in a vertically slidable mode. The lower end of the sliding block is provided with an inclined face. The inclined face at the lower end of the sliding block is attached to the hinge ball head at the right end of the connecting bracket. A driving motor is fixed to a motor support and connected to one end of the crankshaft. The upper end of the connecting rod is hinged to the other end of the crankshaft. The lower end of the connecting rod is hinged to the sliding block. The sliding block type plate feeding device feeds plates continuously and intermittently, and is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a slider-type sheet material feeding device. Background technique [0002] Plates mostly refer to metal plates made of forging, rolling or casting. Divided into thin plate, medium plate, thick plate, extra thick plate, usually made into flat rectangular building material plates of standard size. The shape of the plate product is flat, the ratio of width to thickness is large, and the surface area per unit volume is also large. This shape feature brings its characteristics in use: (1) The surface area is large, so the ability to contain and cover is strong. It is used in chemical industry, containers, construction, and metal products. (2) Can be arbitrarily cut, bent, stamped, welded, and made into various product components. It is flexible and convenient to use, and occupies an extremely important position in the departments of automobile, aviation, shipbuilding an...

Problems solved by technology

(3) Due to the large width-to-thickness ratio and surface area, the rolling pressure in production is very high, which can reach millions to tens of millions of Newtons. Therefore, the rolling mill equipment is complex and huge, and the product width, thickness, dimensional accuracy and plate shape and The control of surface quality has also become very difficult and complicated

At present, the stamping production of sheet metal adopts automatic feeding device. The common feeding device is a set of feeding rollers to realize the feeding of the sheet material. Generally, the ratchet mechanism and the overrunning clutch are used as the intermittent transmission mechanism to realize the intermittent feeding of the sheet material. However, this The structure is more complicated and the cost is higher
