Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of mesh forming machines (mesh punching machines, steel plate mesh machines, expanded mesh machines), specifically a high-efficiency CNC mesh forming machine with a transverse slider displacement device during punching. Background Technology
[0002] Mesh forming machines, also known as mesh punching machines, steel plate mesh machines, or expanded mesh machines, produce a wide range of products with diverse applications, including automotive air filters, car horn mesh, oil filters, sterile workshop air filters, port and dock platforms, highway sound barrier mesh panels, and the main material mesh panels in flat-plate catalysts for desulfurization and denitrification in national air pollution control projects.
[0003] During the stamping process of a screen printing machine, the left and right movement of the horizontal slider is used to misalign the mold, thereby forming a complete eyelet. The precise positioning of the horizontal slider after it moves to its position determines whether the product quality is up to standard. Originally, a planar cam was used to rotate and push a lever, which in turn pushed the horizontal slider to move left and right. This method was slow and inefficient. Especially in today's economic environment that requires high efficiency and zero inventory, the precise positioning under high-speed production has become a research topic. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-efficiency CNC screen forming machine for lateral slider displacement during stamping, so as to solve the problems of slow lateral slider speed and low efficiency in the existing screen forming machine during stamping, and the inability to accurately position the lateral slider after it moves to the position.
[0005] To achieve the above objectives, this utility model proposes a high-efficiency CNC mesh forming machine for lateral slider displacement during stamping, comprising a main body, a motor, a camshaft, a bearing cam, a displacement cam fork, a rod, and a lateral slider;
[0006] The motor is mounted on the main body and connected to the camshaft. The bearing cam is mounted on the camshaft, and the displacement cam fork is sleeved on the bearing cam. At least one inner wall of the displacement cam fork contacts the contour of the bearing cam. The displacement cam fork is connected to one end of the rod, and the other end of the rod is connected to the transverse slider.
[0007] Among them, the bearing cam has an irregular shape profile, or the bearing cam is an eccentric wheel;
[0008] The motor drives the bearing cam mounted on the camshaft to rotate. The profile of the bearing cam causes the displacement cam fork to move left and right, which in turn causes the rod to move left and right, thus causing the transverse slider to slide left and right. When the transverse slider slides to the left or right, it simultaneously causes the stamping die of the screen forming machine to shift one position. This cycle is repeated to form complete eyelets. In this process, the motor is used as the starter and connected to the high-precision and high-strength bearing cam, allowing it to transition and cooperate with the transverse slider to achieve precise positioning. This solves the problems of slow and inefficient transverse slider speed and inability to accurately position the transverse slider after it moves to the correct position in the existing screen forming machine.
[0009] Cam bearings, also known as camshaft bearings, are a type of bearing commonly used in camshafts. They are key components in mechanical transmission systems, consisting of an outer ring, inner ring, rolling elements, and a cage. In various mechanical equipment, they play a crucial role in supporting and transmitting the motion of the cam. Their structural features include the ability to withstand large radial and axial loads, internal lubrication channels, and sealing structures to reduce friction, prevent contaminant intrusion, and improve service life and reliability. Cam bearings are widely used in equipment such as internal combustion engines, automotive transmissions, and machine tools, where they must withstand cyclic loads and impacts to ensure precise fit and motion transmission.

The first piece is used to reduce the noise and vibration generated when the profile of the bearing cam contacts the inner wall of the displacement cam fork, and also has the functions of lubrication and promoting the return of lubricating oil.
[0013] Preferably, the first component is made of one of the following: high-hardness quenched steel, rubber, silicone, leather, high-density sponge, polyester fiber, or nano-cotton.
[0014] Preferably, the first component includes, but is not limited to, high-hardness quenched steel, rubber, silicone, leather, high-density sponge, polyester fiber, and nano-cotton.
[0015] Preferably, it also includes a housing, which is mounted on the main body, and the camshaft, bearing cam, and displacement cam fork are all mounted inside the housing.

[0023] Compared with the prior art, this utility model has the following advantages:
[0024] 1. A motor is connected to a camshaft, a bearing cam is mounted on the camshaft, and a displacement cam fork is sleeved on the bearing cam. At least one inner wall of the displacement cam fork contacts the contour of the bearing cam. The displacement cam fork is connected to one end of a rod, and the other end of the rod is connected to a transverse slider. In this structure, the motor drives the bearing cam mounted on the camshaft to rotate. The contour of the bearing cam drives the displacement cam fork to move left and right, thereby driving the rod to move left and right, which in turn causes the transverse slider to slide left and right. When the transverse slider slides left or right, it synchronously causes the stamping die of the screen forming machine to shift by one position. This cycle is repeated to form complete eyelets. The motor is used as the starter, connected to a high-precision and high-force bearing cam, allowing it to transition with the transverse slider to achieve precise positioning. This solves the problems of slow and inefficient transverse slider speed and inability to accurately position the transverse slider after it moves to the correct position in the existing screen forming machine stamping process.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0033] Among them, the bearing cam 4 has an irregular shape outline, or the bearing cam 4 is an eccentric wheel;
[0034] Motor 2 drives bearing cam 4 mounted on camshaft 3 to rotate. The contour of bearing cam 4 causes displacement cam fork 5 to move left and right, thereby causing rod 6 to move left and right, which in turn causes transverse slider 7 to slide left and right. When transverse slider 7 slides left or right, it synchronously causes the stamping die of the screen forming machine to shift one position. This cycle is repeated to form complete eyelets. In this way, the motor is used as the starter and connected to the high-precision and high-strength bearing cam 4, allowing it to transition and cooperate with the transverse slider to achieve precise positioning. This solves the problems of slow speed and low efficiency of transverse slider during stamping in existing screen forming machines in the background technology, and the inability to accurately position the transverse slider after it moves to the position.
