Description

Technical Field

[0001] The invention relates to the technical field of clamp production, and in particular to a plate for clamp production and a processing technology of the plate. Background Art

[0002] Most of the existing plates for clamps are flat sheet structures. When the sheet plates are subsequently bent and assembled into clamps, the bending force points are not uniform, resulting in the entire clamp having an insufficient bending arc or local tearing after forming, and the rivet is not firm and is easy to fall off. In addition, the existing production process of plates for clamps has the problems of low processing efficiency and poor processing accuracy. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a plate material for clamp production and a processing technology for the plate material. The design scheme has the advantages of uniform force during bending, avoiding tearing of the plate material, simultaneous forming of the rivet sheet and the strip material, and high processing efficiency and processing accuracy.

[0004] The plate material for producing a clamp of the present invention comprises a plate material body, wherein the plate material body comprises a rivet sheet portion, a strip portion and a bending surface.

[0005] As a further improvement of the present invention, the strip portion is stamped and formed in the middle of the plate body.

[0006] The above technical solution, through stamping and in order to ensure the stamping accuracy, changes the stamping method from one-time stamping in the existing technology to multiple stampings, and gradually increases the stamping pressure each time. On the one hand, it can improve the stamping accuracy, and on the other hand, it can facilitate timely adjustments when stamping errors occur, thereby reducing losses.

[0007] As a further improvement of the present invention, there are two rivet pieces and they are integrally formed on the left and right sides of the plate body respectively.

[0008] In the above technical solution, the two rivet pieces have the same size and height, which makes it convenient to perform punching operations at the same position on the rivet pieces, thereby facilitating subsequent bolt assembly and reducing the error caused by punching.

[0009] Improve product quality.

[0010] As a further improvement of the present invention, the bending surface has two surfaces and is respectively formed at the connection positions between the strip portion and the two rivet sheet portions, and the bending surface is an arc surface protruding outward.

[0011] In the above technical solution, the bending surface can effectively improve the ductility of the plate body when bending, so that when the plate body is bent at the thinner strip portion, on the one hand, the bending curvature at the strip portion is guaranteed to be uniform, thereby reducing the degree of distortion of the finished product; on the other hand, the tearing at the strip portion is reduced, thereby reducing the damage rate and improving the production efficiency of the product.

[0012] As a further improvement of the present invention, the plate body is a sheet made of either spring steel or stainless steel.

[0013] In the above technical solution, the whole body of the plate is made of spring steel material with good elasticity, which can facilitate the subsequent clamp forming of the plate body and ensure good toughness in subsequent use.

[0014] In order to achieve the above-mentioned purpose, a processing technology of a plate for clamp production is provided, and the specific processing steps are as follows:

[0015] Step 1: The cutting mechanism cuts out plate bodies of equal size and conveys the plate bodies to the decontamination mechanism for decontamination treatment through the conveying mechanism.

[0016] Step 2: The decontamination mechanism removes dust and oil stains adhering to the surface of the plate body.

[0017] Step 3: Apply lubricating oil on the cleaned sheet body, and use a stamping machine to stamp out the cleaned sheet body, punching out rivet pieces on both sides that are parallel and equidistant, and a strip piece that is concave in the middle, and a bending surface is formed at the connection between the strip piece and the rivet piece after stamping.

[0018] Step 3-1, in order to ensure the stamping accuracy of the sheet body, a punching machine can be used to punch the sheet body multiple times, and the stamping pressure of the punching machine can be gradually increased.

[0019] Step 4: The stamped sheet body is conveyed to the coating mechanism via the conveying device, and the coating mechanism evenly sprays the anti-rust coating on the sheet body.

[0020] Step 5: After the stamping and coating, the plate body is inspected, and the qualified plate body is sent to the storage device or directly enters the assembly equipment.

[0021] In step 2, the decontamination methods include air blowing to remove dust and ultrasonic degreasing.

[0022] In step 3, the depth of the strip portion in the middle of the plate body is 0.5-1.5 mm, the thickness of the rivet portions on both sides of the plate body is 2.5-3.5 mm, and the distance between the two sides of the plate body and the strip portion is 18-38 mm.

[0023] In step 3-1, the punching times are three times, and the pressures of the three punchings are 60T pressure, 80T pressure, and 120T pressure respectively, and the punching time of each time is 2-8 seconds.

[0024] In step 4, the anti-rust coating is one or more combinations of red lead anti-rust coating, iron red phenolic anti-rust coating and iron red alkyd anti-rust coating.

[0025] In step 5, the detection method is to use the naked eye or laser for sampling detection or batch detection, and the detection categories are deformation detection, flatness detection and smoothness detection.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The present invention designs two rivet parts on the plate body and a strip part between the two rivet parts, so that the entire plate body can be effectively bent by first passing through the end face of the strip part which is thinner than the rivet parts on both sides when bending. When bending, the plate body can also bend along the curvature of the bending surface, thereby further improving the stability of the plate body when bending, avoiding the situation that the curvature of the plate body is insufficient or torn during the subsequent bending forming, thereby making the plate body more advantageous for the production of clamps.

[0028] 2. In order to ensure the accuracy of the sheet body during stamping, the present invention uses multiple and gradually pressurized methods to stamp the sheet body, so that the state of the sheet body can be observed in time after a single stamping is completed, which can facilitate the staff to adjust the state of the sheet body or the punching machine in time, thereby achieving the effect of timely stopping losses. Compared with the irreversible phenomenon that occurs in a single stamping in the prior art, it has better stamping accuracy.

[0029] 3. The processing technology of the present invention has strong continuity and the degree of coordination of various components is high, which can effectively improve the processing efficiency. During processing, the dust or oil stains adhering to the plate body can be removed, which can improve the aesthetics of the plate body after forming and facilitate the subsequent clamp forming. In the processing process, anti-rust paint is applied to the plate body, which can effectively provide anti-rust protection for the plate body.

[0030] It is convenient for the storage or subsequent use of the plate body, thereby further improving the quality of the plate body after being assembled into a clamp, making it convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
