Problems solved by technology

When the actual demand is a stainless steel plate with holes, it is necessary to ensure that the roundness and precision of the holes after blanking meet the corresponding technical requirements. There are two main production methods: first, the stainless steel plate is first punched or machined. Processing and drilling, and then fillet welding of multiple stainless steel plates to achieve the purpose of pressing / bending. This method increases the amount of welding and deformation, and increases the production cost; second, after pressing the stainless steel plates first, Then it is punched or machined and drilled. In this method, machining increases the difficulty of hole positioning, the hole accuracy is not high, and the production efficiency is low.

Embodiment Construction

[0028] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] A bending method for a stainless steel perforated plate, the initial state is as figure 1 , including the following steps:

[0030] Step 1: Punch or drill the stainless steel plate 1 in a flat state, such as figure 2 ;

[0031] Step 2: Mark the profiling line 2 where the stainless steel plate needs to be bent, such as image 3 ;

[0032] Step 3: Under the premise of ensuring that the stainless steel plate 1 is not cut off, a straight line gap 4 is intermittently cut along the profiling line 2 corresponding to each hole directly below the hole 3, as shown in Figure 4 ;

[0033] Step 4: Put the stainless steel plate into the profiling equipment for bending along the profiling line, such as Figure 5 ;

[0034] Step 5: Perform single-sided welding and double-sided forming on the gap of the formed stainless steel plate; that is,...

Abstract

The invention discloses a bending method of a stainless steel band pore plate. The bending method is applied to the field of stainless steel part discharging and pressing. The bending method comprisesthe steps that pores are punched or drilled in the stainless steel plate in a flat plate state; a pressing line, needing to be bent, of the stainless steel plate is marked; on the premise of guaranteeing that the stainless steel plate is not cut off, a straight line gap is cut under each pore along the pressing line; the stainless steel plate is put in pressing equipment to be subjected to bending treatment along the pressing line; and the gaps of the formed stainless steel plate are subjected to single-face welding and double-face forming. The problems that in an existing production method,the welding quantity and the deformation quantity are increased, the manufacturing cost is increased, or the pore locating difficulty is increased, the pore precision is not high, and meanwhile the production efficiency is low are mainly solved. By means of the method, under the conditions that material deformation is reduced and the production efficiency is improved, the bending and forming precision of the pores can be guaranteed.

Description

technical field [0001] The invention belongs to the field of blanking and pressing of stainless steel parts, and in particular relates to a bending method of a stainless steel plate with holes. Background technique [0002] In industrial production, it is more and more widely used to press the stainless steel plate after blanking. When the actual demand is a stainless steel plate with holes, it is necessary to ensure that the roundness and precision of the holes after blanking meet the corresponding technical requirements. There are two main production methods: first, the stainless steel plate is first punched or machined. Processing and drilling, and then fillet welding of multiple stainless steel plates to achieve the purpose of pressing / bending. This method increases the amount of welding and deformation, and increases the production cost; second, after pressing the stainless steel plates first, Then it is punched or machined and drilled. In this method, machining increa...
