How To Choose a Trusted Channel Letter Bender Machine Supplier?

Channel Letter Bender Machine

How to select reliable channel letter bender machine suppliers has always been an issue that has plagued corporate users. Choosing the right letter bender machine and the right bender machine mould products need to consider the application of the machine, the bending radius of the part. Thus, it is necessary to choose from the actual situation of the buyers, and based on the above parameters, the channel letter bender machine producers can recommand the most suitable machine. If you choose improperly, it will increase the production cost. It should be noted that the material grade of the bender machine processing plate is also a key factor. Compared with the processing of low carbon steel, higher hardness stainless steel requires more pressure to function normally. If the soft aluminum is bent, the actual bending pressure can be reduced. When using the current bender machine and bender mold, you should carefully look at the machine's tonnage table, and you can get the estimation of the bender machine pressure required under different thickness and different materials.

Channel letter bender machines differ in the nature of their processing and process, so the manufacturers should make a comprehensive consideration in the purchase of bender machines.

It is necessary to carefully consider what to buy from the end use of the machine, the possible deflections of the known machine, and the bend radius of the part. Of course, as a decision maker, you have the responsibility to learn more about the performance, processing range, machining functions, machining accuracy, etc. of the equipment. If you choose it improperly, your production cost will increase, and the channel letter bender machine can not expect to recover the cost. The following is the factors that must be measured at the time of purchase:

1. The first important thing to consider is the part you are going to produce. The point is to buy a machine that can perform the machining task with the shortest workbench and the smallest tonnage.

Carefully consider the material brand and the maximum processing thickness and length. If the most of the products produced are low carbon steel with a thickness of 3 mm and a maximum length of 2500 mm, the free bending force does not have to be greater than 80. However, if you are engaged in a large number of bottomed die forming, you should consider a channel letter bender machine with a capacity of about 150 tons. If the material to be bent in production is 6mm thick and the low carbon steel within 2500mm is free to bend, it is necessary to consider a channel letter bender machine that requires more than 100 tons.

If bent with a bottom punch (corrected bend), then a larger tonnage channel letter bender machine is required. If most of the work pieces bent are 1250mm or shorter, then the tonnage of the bender machine is almost halved, which greatly reduces the cost of acquisition. The length of the machined part is quite important for determining the specifications of the new model.

2. When the channel letter bender machine is working, especially when bending long workpieces, the deformation of the workpiece will be longer. Under the same load, the 2500mm model and slider show four times the 1250mm model deviation. This means that shorter machines require less gasket adjustment to produce qualified parts, reduce gasket adjustment and preparation time. However, the current CNC hydraulic bender machine adds hydraulic deflection compensation function in the production design, which reduces the adjustment of the equipment by the production operators, and improves the bending precision and production efficiency.

The hydraulic deflection compensation function is controlled by the numerical control system, and the hydraulic oil enters the compensation cylinder through the magnetic servo valve and transports the work table upward. At the same time, the deflection compensating force increases as the bending force increases, which serves as a deflection compensation function. The material of the processed material is also a key factor. The load required for stainless steel is typically increased by about 50% compared to mild steel, while most materials are reduced by about 50% on the soft aluminum side. The relevant standard bending pressure parameters are available from the channel letter bender manufacturer, which shows the required bending force per 1000 mm length at different thicknesses and materials.

3. The bending radius of the workpiece during bending of the product is also a factor to be considered. When free bending is used, the bending radius is 0.156 times the opening size of the V-shaped groove. In the free bending process, the V-groove opening size should be 8 times the thickness of the metal material.

The embossing is the same as the bending of the bottom mold except that the front end of the upper mold is machined to the desired bending radius, and the upper and lower punches at the bottom end of the stroke are smaller than the material thickness. The rebound is substantially avoided by applying sufficient pressure (about 10 times the free bend) to force the front end of the upper mold into contact with the material. In order to select the lowest tonnage specification, it is preferred to specify that the bending radius is greater than the thickness of the material and to use the free bending method as much as possible. When the bending radius is large, the quality of the part and its future use are usually not affected.

Bending accuracy requirements are factors that need to be carefully considered. It is this factor that determines whether you need to consider a CNC channel letter bender machine or a general bender machine. If the bending accuracy is within ±0.5° and cannot be changed, the CNC channel letter bender machine must be viewed. The repeatability of the CNC channel letter bender machine slider is generally guaranteed to be ±0.01mm, the precise forming angle must be accurate, and the mold is good. The numerical control channel letter bender machine has a repeatability of ±0.5 mm, which generally produces a deviation of ±2~3° under suitable mold conditions. In addition, the CNC channel letter bender machine is equipped with a quick-loading CNC system and fixtures. This is an undisputed reason when you need to bend many small parts.
