Metal plate bending device

Abstract

The invention relates to the technical field of bending accessory devices, and in particular relates to a metal plate bending device. The metal plate bending device is simple in structure, adjustable in metal plate bending angle and capable of reducing manufacturing cost. The metal plate bending device comprises a base; a supporting block is arranged at the top of the base; a mounting groove which is communicated in the front-back direction is formed in the top of the supporting block; multiple sets of protrusions are arranged on the inner side wall of the mounting groove; the section of each set of protrusions is in an isosceles trapezoid shape; the metal plate bending device further comprises a cylinder; a V-shaped groove which is communicated in the front-back direction is formed in the top of the cylinder; the bottom of the V-shaped groove coincides with the axis of the cylinder; multiple sets of grooves in sliding fit with the multiple sets of protrusions are formed in the outer side wall of the cylinder; the metal plate bending device further comprises a front moving mechanism and a rear moving mechanism; the front moving mechanism comprises a front supporting rod, a front stabilizing rod, a front threaded rod, a front moving block and a front transverse rod; and the rear moving mechanism comprises a rear supporting rod, a rear stabilizing rod, a rear threaded rod, a rear moving block and a rear transverse rod.

Description

technical field [0001] The invention relates to the technical field of bending attachments, in particular to a sheet metal bending device. Background technique [0002] As we all know, bending tools are commonly used tool equipment in the processing of sheet metal products. With the rapid upgrading of products and the arrival of the era of multi-variety and small batch production, the frequency of tool replacement is high. For the production cycle of tools, the standardization requirements are becoming more and more At the same time, it is very important to reduce the weight of the tool and reduce the labor intensity of the mold change. The existing bending tool mainly places the workpiece on the lower tool, and stamps the workpiece through the stamping head of the upper tool to complete the bending of the workpiece.

[0002] As we all know, bending tools are commonly used tool equipment in the processing of sheet metal products. With the rapid upgrading of products and the arrival of the era of multi-variety and small batch production, the frequency of tool replacement is high. For the production cycle of tools, the standardization requirements are becoming more and more At the same time, it is very important to reduce the weight of the tool and reduce the labor intensity of the mold change. The existing bending tool mainly places the workpiece on the lower tool, and stamps the workpiece through the stamping head of the upper tool to complete the bending of the workpiece. The bending angle of the workpiece is mainly determined by the groove of the lower tool, and the bending degree of the bending part of the different workpiece is different in the groove. In the actual production process, because the length of the groove is fixed, each A lower cutting tool can only meet the requirements of one bending process. However, the bending process requirements in actual production are varied, so that the manufacturer must configure a large number of supporting tools, and the cost investment is large.
